- BACKGROUND: Improving survival and extending the longevity of life for all populations requires timely, robust evidence on local mortality levels and trends. The Global Burden of Disease 2015 Study (GBD 2015) provides a comprehensive assessment of all-cause and cause-specific mortality for 249 causes in 195 countries and territories from 1980 to 2015. These results informed an in-depth investigation of observed and expected mortality patterns based on sociodemographic measures.METHODS: We estimated all-cause mortality by age, sex, geography, and year using an improved analytical approach originally developed for GBD 2013 and GBD 2010. Improvements included refinements to the estimation of child and adult mortality and corresponding uncertainty, parameter selection for under-5 mortality synthesis by spatiotemporal Gaussian process regression, and sibling history data processing. We also expanded the database of vital registration, survey, and census data to 14 294 geography-year datapoints. For GBD 2015, eight causes, including Ebola virus disease, were added to the previous GBD cause list for mortality. We used six modelling approaches to assess cause-specific mortality, with the Cause of Death Ensemble Model (CODEm) generating estimates for most causes. We used a series of novel analyses to systematically quantify the drivers of trends in mortality across geographies. First, we assessed observed and expected levels and trends of cause-specific mortality as they relate to the Socio-demographic Index (SDI), a summary indicator derived from measures of income per capita, educational attainment, and fertility. Second, we examined factors affecting total mortality patterns through a series of counterfactual scenarios, testing the magnitude by which population growth, population age structures, and epidemiological changes contributed to shifts in mortality. Finally, we attributed changes in life expectancy to changes in cause of death. We documented each step of the GBD 2015 estimation processes, as well as data sources, in accordance with Guidelines for Accurate and Transparent Health Estimates Reporting (GATHER).FINDINGS: Globally, life expectancy from birth increased from 61·7 years (95% uncertainty interval 61·4-61·9) in 1980 to 71·8 years (71·5-72·2) in 2015. Several countries in sub-Saharan Africa had very large gains in life expectancy from 2005 to 2015, rebounding from an era of exceedingly high loss of life due to HIV/AIDS. At the same time, many geographies saw life expectancy stagnate or decline, particularly for men and in countries with rising mortality from war or interpersonal violence. From 2005 to 2015, male life expectancy in Syria dropped by 11·3 years (3·7-17·4), to 62·6 years (56·5-70·2). Total deaths increased by 4·1% (2·6-5·6) from 2005 to 2015, rising to 55·8 million (54·9 million to 56·6 million) in 2015, but age-standardised death rates fell by 17·0% (15·8-18·1) during this time, underscoring changes in population growth and shifts in global age structures. The result was similar for non-communicable diseases (NCDs), with total deaths from these causes increasing by 14·1% (12·6-16·0) to 39·8 million (39·2 million to 40·5 million) in 2015, whereas age-standardised rates decreased by 13·1% (11·9-14·3). Globally, this mortality pattern emerged for several NCDs, including several types of cancer, ischaemic heart disease, cirrhosis, and Alzheimer's disease and other dementias. By contrast, both total deaths and age-standardised death rates due to communicable, maternal, neonatal, and nutritional conditions significantly declined from 2005 to 2015, gains largely attributable to decreases in mortality rates due to HIV/AIDS (42·1%, 39·1-44·6), malaria (43·1%, 34·7-51·8), neonatal preterm birth complications (29·8%, 24·8-34·9), and maternal disorders (29·1%, 19·3-37·1). Progress was slower for several causes, such as lower respiratory infections and nutritional deficiencies, whereas deaths increased for others, including dengue and drug use disorders. Age-standardised death rates due to injuries significantly declined from 2005 to 2015, yet interpersonal violence and war claimed increasingly more lives in some regions, particularly in the Middle East. In 2015, rotaviral enteritis (rotavirus) was the leading cause of under-5 deaths due to diarrhoea (146 000 deaths, 118 000-183 000) and pneumococcal pneumonia was the leading cause of under-5 deaths due to lower respiratory infections (393 000 deaths, 228 000-532 000), although pathogen-specific mortality varied by region. Globally, the effects of population growth, ageing, and changes in age-standardised death rates substantially differed by cause. Our analyses on the expected associations between cause-specific mortality and SDI show the regular shifts in cause of death composition and population age structure with rising SDI. Country patterns of premature mortality (measured as years of life lost [YLLs]) and how they differ from the level expected on the basis of SDI alone revealed distinct but highly heterogeneous patterns by region and country or territory. Ischaemic heart disease, stroke, and diabetes were among the leading causes of YLLs in most regions, but in many cases, intraregional results sharply diverged for ratios of observed and expected YLLs based on SDI. Communicable, maternal, neonatal, and nutritional diseases caused the most YLLs throughout sub-Saharan Africa, with observed YLLs far exceeding expected YLLs for countries in which malaria or HIV/AIDS remained the leading causes of early death.INTERPRETATION: At the global scale, age-specific mortality has steadily improved over the past 35 years; this pattern of general progress continued in the past decade. Progress has been faster in most countries than expected on the basis of development measured by the SDI. Against this background of progress, some countries have seen falls in life expectancy, and age-standardised death rates for some causes are increasing. Despite progress in reducing age-standardised death rates, population growth and ageing mean that the number of deaths from most non-communicable causes are increasing in most countries, putting increased demands on health systems.

- Our objective was to test whether p53 expression status is associated with survival for women diagnosed with the most common ovarian carcinoma histotypes (high-grade serous carcinoma [HGSC], endometrioid carcinoma [EC], and clear cell carcinoma [CCC]) using a large multi-institutional cohort from the Ovarian Tumor Tissue Analysis (OTTA) consortium. p53 expression was assessed on 6,678 cases represented on tissue microarrays from 25 participating OTTA study sites using a previously validated immunohistochemical (IHC) assay as a surrogate for the presence and functional effect of TP53 mutations. Three abnormal expression patterns (overexpression, complete absence, and cytoplasmic) and the normal (wild type) pattern were recorded. Survival analyses were performed by histotype. The frequency of abnormal p53 expression was 93.4% (4,630/4,957) in HGSC compared to 11.9% (116/973) in EC and 11.5% (86/748) in CCC. In HGSC, there were no differences in overall survival across the abnormal p53 expression patterns. However, in EC and CCC, abnormal p53 expression was associated with an increased risk of death for women diagnosed with EC in multivariate analysis compared to normal p53 as the reference (hazard ratio [HR] = 2.18, 95% confidence interval [CI] 1.36-3.47, p = 0.0011) and with CCC (HR = 1.57, 95% CI 1.11-2.22, p = 0.012). Abnormal p53 was also associated with shorter overall survival in The International Federation of Gynecology and Obstetrics stage I/II EC and CCC. Our study provides further evidence that functional groups of TP53 mutations assessed by abnormal surrogate p53 IHC patterns are not associated with survival in HGSC. In contrast, we validate that abnormal p53 IHC is a strong independent prognostic marker for EC and demonstrate for the first time an independent prognostic association of abnormal p53 IHC with overall survival in patients with CCC.

- Tubo-ovarian high-grade serous carcinomas (HGSC) are highly proliferative neoplasms that generally respond well to platinum/taxane chemotherapy. We recently identified minichromosome maintenance complex component 3 (MCM3), which is involved in the initiation of DNA replication and proliferation, as a favorable prognostic marker in HGSC. Our objective was to further validate whether MCM3 mRNA expression and possibly MCM3 protein levels are associated with survival in patients with HGSC. MCM3 mRNA expression was measured using NanoString expression profiling on formalin-fixed and paraffin-embedded tissue (N = 2355 HGSC) and MCM3 protein expression was assessed by immunohistochemistry (N = 522 HGSC) and compared with Ki-67. Kaplan-Meier curves and the Cox proportional hazards model were used to estimate associations with survival. Among chemotherapy-naive HGSC, higher MCM3 mRNA expression (one standard deviation increase in the score) was associated with longer overall survival (HR = 0.87, 95% CI 0.81-0.92, p < 0.0001, N = 1840) in multivariable analysis. MCM3 mRNA expression was highest in the HGSC C5.PRO molecular subtype, although no interaction was observed between MCM3, survival and molecular subtypes. MCM3 and Ki-67 protein levels were significantly lower after exposure to neoadjuvant chemotherapy compared to chemotherapy-naive tumors: 37.0% versus 46.4% and 22.9% versus 34.2%, respectively. Among chemotherapy-naive HGSC, high MCM3 protein levels were also associated with significantly longer disease-specific survival (HR = 0.52, 95% CI 0.36-0.74, p = 0.0003, N = 392) compared to cases with low MCM3 protein levels in multivariable analysis. MCM3 immunohistochemistry is a promising surrogate marker of proliferation in HGSC.

- Background and objective: We explored which clinical and biochemical variables predict conversion from clinically isolated syndrome (CIS) to clinically definite multiple sclerosis (CDMS) in a large international cohort. Methods: Thirty-three centres provided serum samples from 1047 CIS cases with at least two years' follow-up. Age, sex, clinical presentation, T2-hyperintense lesions, cerebrospinal fluid (CSF) oligoclonal bands (OCBs), CSF IgG index, CSF cell count, serum 25-hydroxyvitamin D3 (25-OH-D), cotinine and IgG titres against Epstein-Barr nuclear antigen 1 (EBNA-1) and cytomegalovirus were tested for association with risk of CDMS. Results: At median follow-up of 4.31 years, 623 CIS cases converted to CDMS. Predictors of conversion in multivariable analyses were OCB (HR = 2.18, 95% CI = 1.71-2.77, p < 0.001), number of T2 lesions (two to nine lesions vs 0/1 lesions: HR = 1.97, 95% CI = 1.52-2.55, p < 0.001; >9 lesions vs 0/1 lesions: HR = 2.74, 95% CI = 2.04-3.68, p < 0.001) and age at CIS (HR per year inversely increase = 0.98, 95% CI = 0.98-0.99, p < 0.001). Lower 25-OH-D levels were associated with CDMS in univariable analysis, but this was attenuated in the multivariable model. OCB positivity was associated with higher EBNA-1 IgG titres. Conclusions: We validated MRI lesion load, OCB and age at CIS as the strongest independent predictors of conversion to CDMS in this multicentre setting. A role for vitamin D is suggested but requires further investigation.

- We report the detection of endometrial and ovarian cancers based on genetic analyses of DNA recovered from the fluids obtained during a routine Papanicolaou (Pap) test. The new test, called PapSEEK, incorporates assays for mutations in 18 genes as well as an assay for aneuploidy. In Pap brush samples from 382 endometrial cancer patients, 81% [95% confidence interval (CI), 77 to 85%] were positive, including 78% of patients with early-stage disease. The sensitivity in 245 ovarian cancer patients was 33% (95% CI, 27 to 39%), including 34% of patients with early-stage disease. In contrast, only 1.4% of 714 women without cancer had positive Pap brush samples (specificity, ~99%). Next, we showed that intrauterine sampling with a Tao brush increased the detection of malignancy over endocervical sampling with a Pap brush: 93% of 123 (95% CI, 87 to 97%) patients with endometrial cancer and 45% of 51 (95% CI, 31 to 60%) patients with ovarian cancer were positive, whereas none of the samples from 125 women without cancer were positive (specificity, 100%). Finally, in 83 ovarian cancer patients in whom plasma was available, circulating tumor DNA was found in 43% of patients (95% CI, 33 to 55%). When plasma and Pap brush samples were both tested, the sensitivity for ovarian cancer increased to 63% (95% CI, 51 to 73%). These results demonstrate the potential of mutation-based diagnostics to detect gynecologic cancers at a stage when they are more likely to be curable.

Tidskriftsartikel (refereegranskat)abstract
- Background: In relapsing-remitting multiple sclerosis (RRMS) the most common treatment strategy has been to start with low-moderate efficacy disease modifying therapy (LE-DMT) and to escalate to more efficacious treatments in cases of breakthrough disease activity. However, recent evidence suggests a better outcome in patients commencing with moderate-high efficacy DMT (HE-DMT) immediately after clinical onset.Objective: The aim of this study is to compare disease activity and disability outcomes in patients treated with the two alternative strategies using the Swedish and Czech national multiple sclerosis registries, taking advantage of the fact that the relative frequency of each strategy differs markedly between these two countries. Methods: Adult RRMS patients who initiated their first-ever DMT between 2013 and 2016 and were included in the Swedish MS register were compared with a similar cohort from the MS register of the Czech Republic using propensity score overlap weighting as a balancing method. The main outcomes of interest were time to confirmed disability worsening (CDW), time to achieve an expanded disability status scale (EDSS) value of 4, time to relapse, and time to confirmed disability improvement (CDI). To support the results, a sensitivity analysis focusing solely on patients from Sweden starting with HE-DMT and patients from the Czech Republic starting with LE-DMT was performed.Results: In the Swedish cohort, 42% of patients received HE-DMT as initial therapy compared to 3.8% of patients in the Czech cohort. The time to CDW was not significantly different between the Swedish and Czech cohorts (p-value 0.2764), with hazard ratio (HR) of 0.89 and a 95% confidence interval (CI) of 0.77-1.03. Patients from the Swedish cohort exhibited better outcomes for all remaining variables. The risk of reaching EDSS 4 was reduced by 26% (HR 0.74, 95%CI 0.6-0.91, p-value 0.0327), the risk of relapse was reduced by 66% (HR 0.34, 95%CI 0.3-0.39, p-value <0.001), and the probability of CDI was three times higher (HR 3.04, 95%CI 2.37-3.9, p-value <0.001).Conclusion: The analysis of the Czech and the Swedish RRMS cohorts confirmed a better prognosis for patients in Sweden, where a significant proportion of patients received HE-DMT as initial treatment.

- Introduction: Some multiple sclerosis (MS) disease-modifying therapies (DMTs) are associated with blunted humoral vaccination responses, but relevance for SARS-CoV-2 infection is unclear.Objectives: To determine SARS-CoV-2 exposure rates and formation of antibody memory among participants of the COMparison Between All immunoTherapies for MS (COMBAT-MS; NCT03193866) and the Immunomodulation and MS Epidemiology (IMSE) studies.Aim: To determine SARS-CoV2 serological response of people living with MS (pwMS).Methods: Using a multiplex bead-based assay we determined SARS-CoV-2 spike and nucleocapsid antibody levels in 3,723 pwMS in paired serum samples (n=7,157) donated prior (Results: Specificity and sensitivity of the assay for SARS-CoV-2 was 100% and 99.7%, respectively. The proportion of positive samples for SARS-CoV-2 differed moderately across DMTs with the highest values among cladribine-treated (7.4%) and the lowest number among rituximab-treated pwMS (3.9%). Similarly, the proportion of positive cases not reported in the Swedish MS registry varied from 100% for cladribine to 33.3% among untreated pwMS. Comparing levels of antibodies titers showed that levels were lower among those treated with rituximab or fingolimod vs interferon treated pwMS. Point estimates indicated a similar trend comparing rituximab or fingolimod vs untreated pwMS.Conclusions: Overall rates of SARS-CoV-2 antibody positivity after the first COVID-19 wave differed only moderately across DMTs, while antibody levels were lower with rituximab or fingolimod compared to interferon-treated pwMS. This indicates quantitative rather than qualitative differences in the humoral response to infection.

Tidskriftsartikel (refereegranskat)abstract
- Background B-cell depleting therapies are highly efficacious in relapsing-remitting multiple sclerosis but one such therapy, rituximab, is not approved for multiple sclerosis and no phase 3 trial data are available. We therefore examined the safety and efficacy of rituximab compared with dimethyl fumarate in patients with relapsing-remitting multiple sclerosis to obtain data that might allow inclusion of rituximab in treatment guidelines. Methods RIFUND-MS was a multicentre, rater-blinded, active-comparator, phase 3, randomised controlled trial done at 17 Swedish university and community hospitals. Key inclusion criteria for participants were: age 18-50 years; relapsing-remitting multiple sclerosis or clinically isolated syndrome according to prevailing McDonald criteria; 10 years or less since diagnosis; untreated or only exposed to interferons or glatiramer acetate; and with clinical or neuroradiological disease activity in the past year. Patients were automatically randomly assigned (1:1) by the treating physician using a randomisation module in the Swedish multiple sclerosis registry, without stratification, to oral dimethyl fumarate 240 mg twice daily or to intravenous rituximab 1000 mg followed by 500 mg every 6 months. Relapse evaluation, Expanded Disability Status Scale rating, and assessment of MRI scans were done by examining physicians and radiologists masked to treatment allocation. The primary outcome was the proportion of patients with at least one relapse (defined as subacute onset of new or worsening neurological symptoms compatible with multiple sclerosis with a duration of more than 24 h and preceded by at least 30 days of clinical stability), assessed in an intention-to-treat analysis using log-binomial regression with robust standard errors. This trial is registered at ClinicalTrials.gov, NCT02746744. Findings Between July 1, 2016, and Dec 18, 2018, 322 patients were screened for eligibility, 200 of whom were randomly assigned to a treatment group (100 assigned to rituximab and 100 assigned to dimethyl fumarate). The last patient completed 24-month follow-up on April 21, 2021. 98 patients in the rituximab group and 97 patients in the dimethyl fumarate group were eligible for the primary outcome analysis. Three (3%) patients in the rituximab group and 16 (16%) patients in the dimethyl fumarate group had a protocol-defined relapse during the trial, corresponding to a risk ratio of 0.19 (95% CI 0.06-0.62; p=0.0060). Infusion reactions (105 events [40.9 per 100 patient-years]) in the rituximab group and gastrointestinal reactions (65 events [47.4 per 100 patient-years]) and flush (65 events [47.4 per 100 patient-years]) in the dimethyl fumarate group were the most prevalent adverse events. There were no safety concerns. Interpretation RIFUND-MS provides evidence that rituximab given as 1000 mg followed by 500 mg every 6 months is superior to dimethyl fumarate in preventing relapses over 24 months in patients with early relapsing-remitting multiple sclerosis. Health economic and long-term safety studies of rituximab in patients with multiple sclerosis are needed.

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Introduction: Direct comparisons across multiple disease-modifying therapies (DMTs) for relapsing-remitting multiple sclerosis (RRMS) are valuable in clinical decision making. COMBAT-MS (NCT03193866) is an observational drug trial capturing data on clinical relapses, lesions on magnetic resonance imaging (MRI), Expanded Disability Status Scale (EDSS), and drug survival, at all Swedish university clinics.Objective: Compare the effectiveness of the most common initial MS therapies in Sweden.Methods: All first-ever MS treatments with injectables (INJ, interferon-β/glatiramer acetate), dimethyl fumarate (DMF), natalizumab (NTZ), and rituximab (RTX), started 2011-01-01 to 2020-12-14, were identified with prospectively recorded outcome data in the Swedish MS Register. Follow-up continued even if the therapy ended. Missing data were imputed using multiple imputation and potential confounding was adjusted for using stabilized inverse probability of treatment weighting with baseline variables: age, sex, MS duration, geographical region, EDSS, and relapses. All comparisons are made against RTX.Results: We included 1936 first-ever therapy episodes: 856 INJ, 341 DMF, 270 NTZ, and 469 RTX. Baseline characteristics differed by DMT, with natalizumab having the youngest patients, shortest MS duration, and the most previous relapses.After adjustment, the hazard ratio (HR) for first relapse vs RTX was for INJ 5.9 (95% confidence interval 3.7; 9.5), DMF 2.8 (1.7; 4.8), and NTZ 1.8 (1.0; 3.3). Similarly, the relative three-year lesion rate was for INJ 6.06 (3.75; 9.80), DMF 3.52 (2.01; 6.17), and NTZ 2.03 (1.14; 3.64). EDSS differences at three years were only marginally different: INJ 0.25 (0.06; 0.44), DMF 0.05 (-0.16; 0.26), and NTZ 0.00 (-0.23; 0.24). In contrast, HR for treatment discontinuation was marked: INJ 32.5 (19.0; 55.7), DMF 20.2 (11.5; 35.4), and NTZ 16.2 (8.9; 29.5).Conclusions: In treatment-naïve patients, RTX was associated with the lowest risk of relapses and MRI lesions, and by far the lowest probability of switching to a second therapy. In contrast, EDSS at 3 years was similar for RTX, DMF, and NTZ, and only slightly higher for INJ. The apparent difference in effectiveness between NTZ and RTX could possibly be explained by the vulnerable period after switching from NTZ, mainly due to JC virus positivity. These findings underscore the importance of tracking long-term outcomes from first DMT start, while considering subsequent therapy switches.

Tidskriftsartikel (refereegranskat)abstract
- BackgroundWe aimed to investigate the potential of serum biomarker levels to predict disability progression in a multicentric real-world cohort of patients with primary progressive multiple sclerosis (PPMS).MethodsA total of 141 patients with PPMS from 18 European MS centres were included. Disability progression was investigated using change in Expanded Disability Status Scale (EDSS) score over three time intervals: baseline to 2 years, 6 years and to the last follow-up. Serum levels of neurofilament light chain (sNfL), glial fibrillar acidic protein (sGFAP) and chitinase 3-like 1 (sCHI3L1) were measured using single-molecule array assays at baseline. Correlations between biomarker levels, and between biomarkers and age were quantified using Spearman's r. Univariable and multivariable linear models were performed to assess associations between biomarker levels and EDSS change over the different time periods.ResultsMedian (IQR) age of patients was 52.9 (46.4-58.5) years, and 58 (41.1%) were men. Median follow-up time was 9.1 (7.0-12.6) years. Only 8 (5.7%) patients received treatment during follow-up. sNfL and sGFAP levels were moderately correlated (r=0.43) and both weakly correlated with sCHI3L1 levels (r=0.19 and r=0.17, respectively). In multivariable analyses, levels of the three biomarkers were associated with EDSS changes across all time periods. However, when analysis was restricted to non-inflammatory patients according to clinical and radiological parameters (n=64), only sCHI3L1 levels remained associated with future EDSS change.ConclusionsLevels of sNfL, sGFAP and sCHI3L1 are prognostic biomarkers associated with disability progression in patients with PPMS, being CHI3L1 findings less dependent on the inflammatory component associated with disease progression.

- Introduction: Data on how processing speed of relapsing-remitting multiple sclerosis patients (RRMS) evolve over time and its association with disability progression is scarce. We analysed the COMparison Between All immunoTherapies for Multiple Sclerosis (CombatMS; NCT03193866), a nationwide observational drug trial in RRMS.Objectives: Identify trajectories of processing speed and disability and their connections after disease modulatory treatment (DMT) start within the RRMS population.Describe patient characteristics associated with trajectory groups.Aim: Model trajectories of processing speed and disability.Methods: We assessed trajectories of oral Symbol Digit Modalities Test (SDMT) and expanded disability status scale (EDSS) from first DMT start using a group-based modeling approach among 1,800 RRMS patients followed 2010-2021. We investigated predictors of trajectories using group membership assignments as a multinomial outcome and calculated conditional probabilities linking membership across the trajectories.Results: We identified four trajectories of processing speed: low SDMT score (mean starting values; MSV=36.7, standard deviation; SD=8.4)-stable (13%), medium score (MSV =50.8, SD=6.7)-minor decrease (52%), medium/high score (MSV=62.9, SD=8.6)-minor decrease (32%), and high score (MSV= 75.2, SD=9.7)-moderate decrease (3%), and four trajectories of disability: no disability-stable (23%), minimal signs-minor increase (45%), minimal disability-moderate increase (27%), and relatively severe disability-moderate increase (5%). Patients with natalizumab as first DMT were less likely to belong to the medium and high processing speed trajectories, relative to the low SDMT score-stable one. Sex, age at DMT start, and geographical region of treatment were associated with medium and high processing speed and with minimal signs and minimal dis-ability trajectories.There was 0% probability of belonging to the relatively severe disability-moderate increase EDSS trajectory if belonging to the high score-moderate decrease SDMT trajectory, and 8% probability of belonging to the no disability-stable EDSS trajectory if belonging to the low score-stable SDMT trajectory.Conclusions: Patients with lower SDMT scores at DMT start did not decline over the years, whereas those with minimal or relatively severe disability moderately lost function. Our results also suggest an inverse link between processing speed and disability trajectories after DMT start.

- Background: Patients with asthma often suffer from frequent respiratory viral infections and reduced virus clearance. Lung resident memory T cells provide rapid protection against viral reinfections. Objective: Because the development of resident memory T cells relies on the lung microenvironment, we investigated the impact of allergen sensitization on the development of virus-specific lung resident memory T cells and viral clearance. Methods: Mice were sensitized with house dust mite extract followed by priming with X47 and a subsequent secondary influenza infection. Antiviral memory T-cell response and protection to viral infection was assessed before and after secondary influenza infection, respectively. Gene set variation analysis was performed on data sets from the U-BIOPRED asthma cohort using an IFN-γ–induced epithelial cell signature and a tissue resident memory T-cell signature. Results: Viral loads were higher in lungs of sensitized compared with nonsensitized mice after secondary infection, indicating reduced virus clearance. X47 priming induced fewer antiviral lung resident memory CD8 T cells and resulted in lower pulmonary IFN-γ levels in the lungs of sensitized as compared with nonsensitized mice. Using data from the U-BIOPRED cohort, we found that patients with enrichment of epithelial IFN-γ–induced genes in nasal brushings and bronchial biopsies were also enriched in resident memory T-cell–associated genes, had more epithelial CD8 T cells, and reported significantly fewer exacerbations. Conclusions: The allergen-sensitized lung microenvironment interferes with the formation of antiviral resident memory CD8 T cells in lungs and virus clearance. Defective antiviral memory response might contribute to increased susceptibility of patients with asthma to viral exacerbations.

- Increased cerebrospinal fluid neurofilament light (NfL) is a recognized biomarker for neurodegeneration that can also be assessed in blood. Here, we investigate plasma NfL as a marker of neurodegeneration in 13 neurodegenerative disorders, Down syndrome, depression and cognitively unimpaired controls from two multicenter cohorts: King's College London (n = 805) and the Swedish BioFINDER study (n = 1,464). Plasma NfL was significantly increased in all cortical neurodegenerative disorders, amyotrophic lateral sclerosis and atypical parkinsonian disorders. We demonstrate that plasma NfL is clinically useful in identifying atypical parkinsonian disorders in patients with parkinsonism, dementia in individuals with Down syndrome, dementia among psychiatric disorders, and frontotemporal dementia in patients with cognitive impairment. Data-driven cut-offs highlighted the fundamental importance of age-related clinical cut-offs for disorders with a younger age of onset. Finally, plasma NfL performs best when applied to indicate no underlying neurodegeneration, with low false positives, in all age-related cut-offs.

- Using the ImmunoChip custom genotyping array, we analyzed 14,498 subjects with multiple sclerosis and 24,091 healthy controls for 161,311 autosomal variants and identified 135 potentially associated regions (P < 1.0 × 10(-4)). In a replication phase, we combined these data with previous genome-wide association study (GWAS) data from an independent 14,802 subjects with multiple sclerosis and 26,703 healthy controls. In these 80,094 individuals of European ancestry, we identified 48 new susceptibility variants (P < 5.0 × 10(-8)), 3 of which we found after conditioning on previously identified variants. Thus, there are now 110 established multiple sclerosis risk variants at 103 discrete loci outside of the major histocompatibility complex. With high-resolution Bayesian fine mapping, we identified five regions where one variant accounted for more than 50% of the posterior probability of association. This study enhances the catalog of multiple sclerosis risk variants and illustrates the value of fine mapping in the resolution of GWAS signals.

Tidskriftsartikel (refereegranskat)abstract
- Simple Summary Ovarian cancer is the deadliest among gynecological cancers, and there is a huge demand for new treatments for these patients. Immunotherapy holds great potential in cancer treatment, but has not yet proven successful for the majority of ovarian cancer patients. To better understand the immunological landscape of the disease, we have characterized lymphocytes in patients with high-grade serous ovarian cancer. Natural killer cells and T cells are present in both primary tumors and in the metastasizing environment of ascites, a fluid in the abdominal cavity that is developed in many patients with ovarian cancer. Our data reveal that a large fraction of these natural killer cells and T cells express tissue-resident markers and the inhibitory receptor, NKG2A, and are able to kill ovarian cancer cells. In summary, we report a functional subset of lymphocytes that may be targeted in future immunotherapeutic approaches. Women with ovarian cancer have limited therapy options, with immunotherapy being unsatisfactory for a large group of patients. Tumor cells spread from the ovary or the fallopian tube into the abdominal cavity, which is commonly accompanied with massive ascites production. The ascites represents a unique peritoneal liquid tumor microenvironment with the presence of both tumor and immune cells, including cytotoxic lymphocytes. We characterized lymphocytes in ascites from patients with high-grade serous ovarian cancer. Our data reveal the presence of NK and CD8(+) T lymphocytes expressing CD103 and CD49a, which are markers of tissue residency. Moreover, these cells express high levels of the inhibitory NKG2A receptor, with the highest expression level detected on tissue-resident NK cells. Lymphocytes with these features were also present at the primary tumor site. Functional assays showed that tissue-resident NK cells in ascites are highly responsive towards ovarian tumor cells. Similar results were observed in an in vivo mouse model, in which tissue-resident NK and CD8(+) T cells were detected in the peritoneal fluid upon tumor growth. Together, our data reveal the presence of highly functional lymphocyte populations that may be targeted to improve immunotherapy for patients with ovarian cancer.

- Background: Dimethyl fumarate (DMF) is an oral therapy for relapsing-remitting multiple sclerosis (RRMS), which has been included in the Swedish post-market surveillance study “Immunomodulation and Multiple Sclerosis Epidemiology 5” (IMSE 5) in order to monitor and determine the long-term safety and effectiveness in a real-world setting.Objectives: To follow-up the long-term safety and effectiveness of DMF in a real-world setting.Methods: MS patients are registered into the nationwide Swedish Neuro Registry (NeuroReg) in Sweden. The IMSE 5 study obtains descriptive data of adverse events (AEs), Extended Disability Status Scale (EDSS), Multiple Sclerosis Severity Scale (MSSS), Symbol Digit Modalities Test (SDMT), Multiple Sclerosis Impact Scale (MSIS-29), European Quality of Life - Five Dimensions Test (EQ-5D) and Visual Analog Scale (VAS) from NeuroReg. Drug survival was measured using the Kaplan-Meier curve and effectiveness measures were assessed using the Wilcoxon Signed Rank Test.Results: 2010 DMF-treated patients have been included in the IMSE 5 study between March 2014 and April 2018. 73 % were female and the mean age at treatment start was 40.6 years. The mean treatment duration was 22.3 months. 92 % of the patients had RRMS with 2 % missing data on MS phenotype. Most patients switched from interferon and glaimer acetat (41 %) and 24 % of the patients were treatment naïve (13 % were missing data on prior treatment). The overall one year drug survival was 74 % and 889 patients terminated their treatment at some point. Most patients (39 %) switched to rituximab (15 % have no new treatment registered). The most common reason for discontinuation was AEs (53 %) and lack of effect (29 %). 227 (11 %) patients have continued treatment for ≥36 months. In patients treated with DMF continuously for ≥24 months (n=918), significant improvements in mean values at 24 months of treatment compared to mean baseline values have been noted for EDSS (1.9 ± 1.6 to 1.6 ± 1.6, n=196); MSSS (2.5 ± 2.4 to 2.0 ± 2.0, n=145); SDMT (52.6 ± 11.0 to 53.8 ± 11.7, n=315); MSIS-29 Psychological Subscale (26.3 ± 22.8 to 21.8 ± 20.6, n=337); and EQ-5D (0.76 ± 0.23 to 0.81 ± 0.20, n=284).Conclusions: NeuroReg proves to function well as a post-marketing drug surveillance platform, providing data regarding drug effectiveness and AEs. A longer follow-up period is needed to assess the real-world effectiveness and safety of DMF.

The IMSE 4 study obtains descriptive data of adverse events (AEs), Extended Disability Status Scale (EDSS), Multiple Sclerosis Severity Scale (MSSS), Symbol Digit Modalities Test (SDMT), Multiple Sclerosis Impact Scale (MSIS-29), European Quality of Life - Five Dimensions Test (EQ-5D) and Visual Analog Scale (VAS) from NeuroReg. Drug survival was measured using the Kaplan-Meier curve.Results: 481 TFM-treated patients have been included in the IMSE 4 study between March 2014 and April 2018. 70 % were female and the mean age at treatment start was 45.8 years. The mean treatment duration was 20.5 months. 89 % of the patients had RRMS with 3 % missing data on MS phenotype. Most patients switched from interferon and glatimer acetat (37 %) and 14 % of the patients were treatment naïve before starting TFM. The overall one year drug survival rate was 81 % and the overall two year drug survival rate was 41 %. 168 (35 %) patients terminated their treatment at some point, of which 33 % started rituximab treatment and 22 % have no new treatment registered. The most common reasons for discontinuation were AEs (49 %) and lack of effect (40 %). 318 patients have been continuously treated with TFM for ≥12 months and mean baseline values compared to val-ues at 12 months have been noted for EDSS (2.0 ± 1.5 to 2.2 ± 1.5, n=141); MSSS (2.6 ± 2.2 to 2.9 ± 2.3, n=126); SDMT (50.8 ± 10.5 to 50.8 ± 10.7, n=165); MSIS-29 Physiological subscale (20.2 ± 19.3 to 19.7 ± 20.0, n=181); MSIS-29 Psychological subscale (28.1 ± 22.2 to 23.7 ± 21.7, n=181); EQ-5D (0.74 ± 0.24 to 0.73 ± 0.26, n=154); and VAS (70.0 ± 20.8 to 70.8 ± 19.6, n=150).Conclusions: NeuroReg proves to function well as a post-marketing drug surveillance platform, providing data regarding drug effectiveness and AEs. However, a longer follow-up period is needed to assess the real-world effectiveness and safety of TMF.

- Background: Alemtuzumab (ALZ) is a modulatory drug for patients with relapsing-remitting multiple sclerosis (RRMS). Post-marketing surveillance is important to assess the long-term safety and effectiveness in a real-world setting where ALZ was included into the Swedish post-market surveillance study “Immunomodulation and Multiple Sclerosis Epidemiology Study 3” (IMSE 3) upon launch in Sweden (March 2014).Objective: To follow up the effectiveness and long-term safety of ALZ in a real-world setting.Methods: Swedish MS patients are registered in the nationwide Swedish Neuro Registry (NeuroReg).IMSE 3 includes patients starting ALZ treatment with annual clinical measures obtained from NeuroReg; Extended Disability Status Scale (EDSS), Multiple Sclerosis Severity Scale (MSSS), Symbol Digit Modalities Test (SDMT), Multiple Sclerosis Impact Scale (MSIS-29), European Quality of Life – 5 Dimension Test (EQ-5D) and Visual Analogue Scale (VAS). The Wilcoxon signed-rank test was used to assess changes in effectiveness.Results: 118 patients (59% female; 95% RRMS) have been included in IMSE 3 between March 2014 and April 2021. Mean age at treatment start was 34 years. At cut-off date 85 patients had been treated with ALZ with at least 48 months of follow-up. Mean values at baseline compared to 48 months showed significant improvements for MSSS and SDMT while EQ-5D, EDSS, MSIS-29 and VAS scores showed tendencies of improvement.The largest proportion of the entire cohort switched from natalizumab (39%) or were treatment naïve (14%) prior ALZ. The number of relapses per 1,000 patient years decreased from 441 before ALZ initiation to 84 during ALZ treatment (16% missing data). 36 adverse events (AEs) were reported to the Swedish Medical Products Agency. 23 were classified as serious and the most common AEs categories were infections and infestations and blood and lymphatic system disorders (23% respectively). For non-serious events endocrine disorders (43%) was the most common category. Two patients died during ALZ treatment, one of which was associated to ALZ treatment, and died in association with the first ALZ treatment cycle due to fulminant viral hepatitis.Conclusions: Patients treated with ALZ for at least 48 months improved or remained stable across all effectiveness measures. Continued follow-up is needed to evaluate the real-world effectiveness and safety of ALZ.

- Background: Subcutaneous peginterferon beta-1a (PegIFN) was approved for relapsing-remitting multiple sclerosis (RRMS) in Europe 2014. Phase II and III studies have shown that PegIFN reduces relapse rate and disability progression. PegIFN were included in the Swedish “Immunomodulation and Multiple Sclerosis Epidemiology Study” (IMSE 6) due to the importance of studying the long-term safety and effectiveness.Objectives: To follow-up the long-term safety and effectiveness of PegIFN in a real-world setting.Methods: Data was obtained from the Swedish Neuro Registry (NeuroReg). All clinical measures; Extended Disability Status Scale (EDSS), Multiple Sclerosis Severity Scale (MSSS), Symbol Digit Modalities Test (SDMT), Multiple Sclerosis Impact Scale (MSIS-29), European Quality of Life - 5 Dimensions Test (EQ-5D), Visual Analog Scale (VAS) were assessed using the Wilcoxon Signed Rank Test and drug survival using the Kaplan-Meier curve.Results: 393 patients (78% female; 86% RRMS) were included in IMSE 6 between June 2015 and April 2021. Mean age at treatment start was 42 years, mean treatment duration was 23 months. 25% were treatment naïve and 47% switched from other injectables prior PegIFN. The one- and two-year drug survival rate was 58% and 41% respectively, and 31% overall. In total, 271 patients discontinued their PegIFN treatment at some time point, mainly due to adverse events (51%) and lack of effect (26%). Most patients switched to rituximab (37%). During the entire treatment period 54% were relapse-free and 8% had only one relapse (36% missing data). In patients treated at least 24 months tendencies of improve-ments were seen for SDMT and EQ-5D. MSIS-PSYCH showed significantly worsened results (21.2 ± 18.6 to 24.3 ± 19.3, n=46). EDSS, MSSS, MSIS-PHYS and VAS scores remained stable. 25 adverse events (AEs) have been reported to Swedish Medical Product Agency (MPA). 6 of these were classified as serious where general disorders and administration site, and skin (33% respectively) were the most common categories. General disorders and administration site were also the most common for non-serious AEs (68%).Conclusions: NeuroReg proves to function well as a post-marketing drug surveillance platform. All clinical effectiveness measures, except MSIS-PHYS, remained stable in patients treated for at least 24 months in this nationwide population-based real-world study. Longer follow up is needed to address the long-term effectiveness.

- Background: Natalizumab (NTZ) is a highly effective disease modulatory treatment for relapsing-remitting multiple sclerosis (RRMS). Post-marketing surveillance is important for evaluation of long-term safety and effectiveness in a real-world setting. The “Immunomodulation and Multiple Sclerosis Epidemiology Study” (IMSE 1) was initiated upon NTZ launch in Sweden (August 2006).Objective: To follow-up the long-term effectiveness and safety of NTZ in a real-world setting.Methods: IMSE 1 includes patients starting NTZ treatment. Data is collected from the nationwide Swedish Neuroregistry. Adverse events (AEs), JC-virus status (JCV) and clinical effectiveness measures Extended Disability Status Scale (EDSS), Multiple Sclerosis Severity Scale (MSSS), Multiple Sclerosis Impact Scale (MSIS-29) and Symbol Digit Modalities Test (SDMT) are registered prospectively.Results: 3476 patients (75% female; 81% RRMS) were included from August 2006 until April 2021. Mean age at treatment start was 36 years and mean treatment duration was 51.3 months. 1190 patients were currently treated with NTZ at cut-off and 13% of these were JCV positive (JCV+) with a mean JCV index at 1.07 ± 0.97. 2470 patients (71%) discontinued their NTZ treatment at some time point where the main reason was JCV+ (40%). Most of these patients switched to rituximab (39%). The number of relapses per 1,000 patient years were reduced from 380 before treatment start to 73 during treatment (25% missing data). 61% were relapse-free and 12% had only one relapse during the entire treatment period. All clinical measures showed improvement in mean between baseline and 132 months. Improvements on MSSS, MSIS-29 and SDMT were statistically significant. 117 Serious AEs had been reported to the Swedish Medical Product Agency and included nine cases (2 fatal) of progressive multifocal leukoencephalopathy (PML). Eight of these nine cases had been reported between year 2008 and 2012, and one in 2018. 17 patients died within 6 months of last NTZ infusion. The most common category for non-serious AEs was infections and infestations (21%). For serious AEs neoplasms benign, malignant and unspecified were the most common (16%).Conclusions: NTZ is generally well tolerated with sustained effectiveness regarding clinical cognitive, physical and psychological measures.

- Background: Teriflunomid (TFM) is a newly approved oral therapy for relapsing-remitting multiple sclerosis (RRMS), which has been included in the Swedish post-market surveillance study “Immunomodulation and Multiple Sclerosis Epidemiology” (IMSE) in order to track the long-term safety and effectiveness in a real-world setting.Objectives: To track the long-term safety and effectiveness of TFM in a real-world setting.Methods: A large majority of MS patients are registered into the nationwide Swedish Neuro Registry (NeuroReg). The IMSE 4 study obtains descriptive data of adverse events (AEs), Extended Disability Status Scale (EDSS), Multiple Sclerosis Severity Scale (MSSS), Symbol Digit Modalities Test (SDMT), Multiple Sclerosis Impact Scale (MSIS-29), European Quality of Life - Five Dimensions Test (EQ-5D) and Visual Analog Scale (VAS) from NeuroReg. Drug survival was measured using the Kaplan-Meier curve.Results: A total of 559 TFM-treated patients had been included in the IMSE 4 study from March 2014 to March 2019. 71 % were female and the mean age at treatment start was 46 years. The mean treatment duration was 23 months and 89 % of the patients had RRMS (9 % missing data on MS phenotype). Most patients switched from interferon/glatiramer acetate (36 %) and 16 % of the patients were treatment naïve before starting TFM. The overall one-year drug survival rate was 74 % and the overall two-year drug survival rate was 58 %. 232 (42 %) patients had terminated their treatment at some point, of which 46 % started rituximab treatment and 12 % had no new treatment registered. The most common reasons for discontinuation were AEs (41 %) and lack of effect (39 %). 229 patients had been continuously treated with TFM for ⩾24 months and significant changes in mean baseline values compared to values at 24 months were noted for EDSS (1.9 ± 1.5 to 2.1 ± 1.6, n=66) and SDMT (50.3 ± 10.5 to 52.3 ± 13.0, n=88). A total of 34 AEs were reported to the Swedish Medical Products Agency of which 9 events were classified as serious, none fatal.Conclusions: NeuroReg proves to function well as a post-marketing drug surveillance platform, providing data regarding drug effectiveness and AEs. Patients starting TMF are older at treat-ment start than most other DMTs, which may explain the lack of improvement in EDSS scores. Still, a relatively high proportion switched due to lack of effect. A longer follow-up period is needed to assess the real-world effectiveness and safety of TMF.

- Background: Dimethyl fumarate (DMF) is an oral therapy for relapsing-remitting multiple sclerosis (RRMS). DMF is included in the Swedish post-market surveillance study “Immunomodulation and Multiple Sclerosis Epidemiology” (IMSE).Objectives: To assess the effectiveness and safety of DMF with focus on patients treated at least 36 months in the IMSE study.Methods: Descriptive data of Extended Disability Status Scale (EDSS), Multiple Sclerosis Severity Scale (MSSS), Symbol Digit Modalities Test (SDMT), Multiple Sclerosis Impact Scale (MSIS-29), European Quality of Life - 5 Dimensions Test (EQ-5D), Visual Analog Scale (VAS) and Adverse Events (AEs) is obtained from the nationwide Swedish Neuro Registry (NeuroReg). Effectiveness measures were assessed using the Wilcoxon Signed Rank Test and drug survival using the Kaplan-Meier curve.Results: 2349 DMF-treated patients were included between March 2014 and June 2020 with an overall drug survival rate of 45%. The main reasons for discontinuation were AEs (50%) and lack of effect (30%). 186 AEs were reported to the Swedish Medical Products Agency, of which 59 were serious. A total of 8 patients have died during DMF treatment or within 6 months of treatment discontinuation. 36 month cohort: 940 patients had con-tinuous treatment for at least 36 months. This cohort had a mean age of 42 years and a mean treatment duration of 56 months. The majority (50%) had switched from interferon or glatiramer ace-tate, and (24%) were treatment naïve (TN). Significant improve-ments in mean values at 36 months of treatment compared to baseline for the 36-month cohort were noted for MSSS, SDMT, MSIS-29 Psychological, EQ-5D and VAS. When TN patients were solely assessed (n=230) improvements were noted for all above mentioned measures as well as MSIS-29 Psychological. The remaining patients in the cohort; treatment experienced patients (n=710) displayed significant improvements only for MSSS, MSIS-29 Psychological and EQ-5D. TN patients had a mean duration from diagnosis to treatment start of 5 months com-pared to 91 months for the remaining cohort. TN were also younger than the remaining cohort (37 years vs 43 years).Conclusions: DMF demonstrates clinical improvements in patients treated 36 months, more pronounced in TN patients. However; due to the high discontinuation rate there is an unavoidable selection bias. Continued follow up is needed to assess the effectiveness and safety of DMF over longer time periods in a real world setting.

- Background: Cladribine is a deoxyadenosine analogue prodrug. Cladribine tablets (CT) are administered in two courses, 12 months apart, for patients with relapsing multiple sclerosis (RMS). CT are included in the Swedish post-market surveillance study “Immunomodulation and Multiple Sclerosis Epidemiology” (IMSE).Objectives: To assess the safety and effectiveness of CT in a real-world setting with focus on patients treated at least 12 months.Methods: Descriptive data of Extended Disability Status Scale (EDSS), Multiple Sclerosis Severity Scale (MSSS), Symbol Digit Modalities Test (SDMT), Multiple Sclerosis Impact Scale (MSIS-29), European Quality of Life - 5 Dimensions Test (EQ-5D), Visual Analog Scale (VAS), relapses and Adverse Events (AEs) is obtained from the nationwide Swedish Neuro Registry (NeuroReg). Effectiveness measures were assessed using the Wilcoxon Signed Rank Test and relapse rates were tested using the paired samples T-test.Results: 85 patients were included in the IMSE 10 study since CT were introduced on the Swedish market in April 2018. 42 patients were treated for at least 12 months. Five AEs were reported since the study start, four were classified as infections and infestations. 25 % of the entire cohort was treated with CT as their first MS drug. 13 % were treated with natalizumab and 12 % with dimethyl fumarate prior to CT. Five AEs were reported since the study start, four were classified as infections and infestations. Relapse data was available for 27/42 patients in the 12-month cohort. The number of reported relapses decreased significantly from 208.6 per 1,000 patient years before treatment start to 83.6 during treatment. Only three patients in this cohort experienced a relapse during treatment of which two were during the first treatment year. Significant improvements in mean values at 12 months of treatment compared to baseline were noted for MSSS for the 12-month cohort (n=17). All other tests remained stable but significantly unchanged after one year of treat-ment. Lymphocyte levels decreased from a mean of 2.4 x 109/L at treatment start (n=8) to 1.2 x 109/L after 12 months of treatment (n=6) in the 12-month cohort. No patients were below the 0.8 x 109/L limit at 12 months.Conclusions: CT treatment demonstrates clinical stability in patients treated 12 months. However, continued follow-up is needed to assess the effectiveness and safety of CT over a longer time to assess if these results sustain after the final treatment course has been administered.

- Background: Teriflunomid (TFM) is an oral therapy for relaps-ing-remitting multiple sclerosis (RRMS), which has been included in the Swedish post-market surveillance study “Immunomodulation and Multiple Sclerosis Epidemiology” (IMSE).Objectives: To assess the long-term safety and effectiveness of TFM for patients treated in a real-world setting over time.Methods: A large majority of MS patients are registered into the nationwide Swedish Neuro Registry (NeuroReg). The IMSE 4 study obtains descriptive data of adverse events (AEs), Extended Disability Status Scale (EDSS), Multiple Sclerosis Severity Scale (MSSS), Symbol Digit Modalities Test (SDMT), Multiple Sclerosis Impact Scale (MSIS-29), European Quality of Life - Five Dimensions Test (EQ-5D) and Visual Analog Scale (VAS) from NeuroReg. Effectiveness measures were assessed using the Wilcoxon Signed Rank Test and drug survival using the Kaplan-Meier curve.Results: 609 TFM-treated patients had been included in the IMSE 4 study from March 2014 to June 2020, 70% were female and mean age at treatment start was 46 years. Mean treatment duration was 27 months and 89% of the patients had RRMS. The most common prior treatment was interferon beta or glatiramer acetate (39%) and 17% of the patients were treatment naïve. The overall one- two- and three- year drug survival rates were 73%, 59% and 48% respectively. 307 (50%) patients had discontinued treatment at some point, of which 34% started rituximab treatment (36% had no new treatment registered). The most common rea-sons for discontinuation were AEs (42%) and lack of effect (40%). 204 patients had been continuously treated with TFM for ⩾36 months and significant changes in mean baseline values compared to values at 36 months were noted only for EDSS (2.0 ± 1.6 to 2.3 ± 1.8, n=49). All other clinical measures were stable. A total of 68 AEs were reported of which 20 events were classified as serious (S). The most common AE category was skin and subcutaneous tissue disorders for both serious and non-serious (NS) AEs (S: 25%, NS: 21%).Conclusions: NeuroReg proves to function well as a post-market-ing drug surveillance platform, providing data regarding drug effectiveness and AEs. Patients starting TMF are older at treat-ment start than patients initiating most other DMTs, which may explain the lack of significant improvement in most clinical meas-ures and the negative outcome of the EDSS scores. A longer fol-low-up period is needed to assess the real-world effectiveness and safety of TMF.

- Introduction: Dimethyl fumarate (DMF) is an oral therapy for relapsing-remitting multiple sclerosis (RRMS). DMF is included in the Swedish post-market surveillance study “Immunomodulation and Multiple Sclerosis Epidemiology” (IMSE).Objectives/Aims: To assess the effectiveness and safety of DMF with focus on patients treated at least 72 months.Methods: Descriptive data of Extended Disability Status Scale (EDSS), Multiple Sclerosis Severity Scale (MSSS), Symbol Digit Modalities Test (SDMT), Multiple Sclerosis Impact Scale (MSIS-29), European Quality of Life - 5 Dimensions Test (EQ-5D), Visual Analog Scale (VAS), Adverse Events (AEs) and Serious AEs (SAEs) is obtained from the nationwide Swedish Neuro Registry (NeuroReg). Effectiveness measures were assessed using the Wilcoxon Signed Rank Test and drug survival using the Kaplan-Meier curve.Results: 2565 DMF-treated patients were included between March 2014 and March 2022 with an overall drug survival rate of 38.7% and a mean treatment duration of 37 months. The main reasons for discontinuation were AEs (47%) and lack of effect (30%). 199 AEs were reported of which 63 were serious. For both serious and non-serious AEs reported, gastrointestinal disorders were the most common (19% and 27%, respectively).509 patients had continuous treatment for at least 72 months. This cohort had a mean age of 42 years and a mean treatment duration of 84 months. The majority (51%) had switched from interferon or glatiramer acetate and 24% were treatment naïve.Significant improvements in mean values at 72 months of treatment compared to baseline were noted for MSSS, MSIS-29 Psychological, and EQ-5D (p<0.05). All other tests remained stable after 6 years of treatment. Number of relapses per 1000 patient years were improved from 199.6 before DMF treatment start to 23.0 during treatment with DMF.49 patients (10%) have discontinued DMF treatment in the 72 month cohort with a mean treatment duration of 84 months (range 70-97 months). The main reasons for discontinuation were other reasons (33%), lack of effect (29%), stable condition (14%), and AEs (12%).Conclusions: DMF demonstrates partly clinical improvements in patients treated 72 months. However; due to the high discontinuation rate there is an unavoidable selection bias. Continued follow up is needed to assess the effectiveness and safety of DMF over longer time periods in a real world setting.

- Background: Dimethyl fumarate (DMF) is an oral therapy for relapsing-remitting multiple sclerosis (RRMS). DMF is included in the Swedish post-market surveillance study “Immunomodulation and Multiple Sclerosis Epidemiology” (IMSE).Objective: To assess the effectiveness and safety of DMF with focus on patients treated at least 36 months in the IMSE study.Methods: Descriptive data of Extended Disability Status Scale (EDSS), Multiple Sclerosis Severity Scale (MSSS), Symbol Digit Modalities Test (SDMT), Multiple Sclerosis Impact Scale (MSIS-29), European Quality of Life - 5 Dimensions Test (EQ-5D), Visual Analog Scale (VAS) and Adverse Events (AEs) is obtained from the nationwide Swedish Neuro Registry (NeuroReg). Effectiveness measures were assessed using the Wilcoxon Signed Rank Test and drug survival using the Kaplan-Meier curve.Results: 2229 DMF-treated patients were included since March 2014 with a one- and two-year drug survival rate of 73% and 59%. The main reasons for discontinuation were AEs (51%) and lack of effect (29%). 77 AEs were reported to the Swedish Medical Products Agency of which 20 were serious. There were 6 fatal cases of which 4 were confirmed as unrelated to DMF and 2 were still under investigation.865 patients had continuous treatment for at least 36 months. This cohort had a mean age of 42 years and a mean treatment duration of 44 months. The majority had switched from interferon and glatiramer acetate (IFN&GA) (50%) or were treatment naïve (TN) (22%). Significant improvements in mean values at 36 months of treatment compared to baseline were noted for EDSS, MSSS, SDMT, MSIS-29 Psychological and EQ-5D. When TN patients were solely assessed improvements were noted for EDSS, MSSS, SDMT, MSIS-29 Physical and Psychological and EQ-5D. Treatment experienced patients displayed significant improvements only for MSSS and EQ-5D. Patients previously treated with IFN&GA also improved only in MSSS and EQ-5D. TN patients had a mean duration from diagnosis to treatment start of 6 months compared to 83 months for IFN&GA patients and 105 months for the remaining cohort.Conclusions: DMF demonstrates clinical improvements in patients treated ⩾ 36 months, most pronounced in TN patients. However; the tolerability of DMF was reduced since 41% interrupted treatment during the first 24 months of therapy. Continued follow up is needed to assess the effectiveness and safety of DMF over longer time periods in a real world setting.

- Introduction: Natalizumab (NTZ) is a highly effective disease modulatory treatment for relapsing-remitting multiple sclerosis (RRMS). Post-marketing surveillance is important for evaluation of long-term safety and effectiveness in a real-world setting. To this end the “Immunomodulation and Multiple Sclerosis Epidemiology Study” (IMSE 1) was initiated upon NTZ launch in Sweden (Aug 2006).Objectives/Aims: To follow-up the long-term effectiveness and safety of NTZ in a real-world setting.Methods: Adverse events (AEs), Serious AEs (SAEs), John Cunningham virus status (JCV) and clinical effectiveness measures; Extended Disability Status Scale (EDSS), Multiple Sclerosis Severity Scale (MSSS), Symbol Digit Modalities Test (SDMT) and Multiple Sclerosis Impact Scale (MSIS-29) data is collected from the nationwide Swedish Neuro Registry (NeuroReg). Effectiveness measures were assessed using the Wilcoxon Signed Rank Test.Results: A total of 3622 NTZ patients were included in the IMSE 1 study from August 2006 until March 2022 (72% female; mean age 36 years; 80% RRMS; mean treatment duration 49 months) and 186 had been treated for at east 132 months. Of the 132-month cohort, 73% were female, the mean age was 36 years, 88% had RRMS, and the mean treatment duration was 155 months. The majority were treated with interferons and glatiramer acetate prior NTZ (64%). 25% (47/186) discontinued NTZ treatment of which 47% (n=22) discontinued due to JCV positive (JCV+). In total, 30% (55/186) of these patients were JCV+ with a mean JCV index of 1.2±1.0 (2% missing data). Relapses before treatment were reduced from 380/1000 patient years to 43/1000 during treatment, 71% were relapse-free and 18% had 1 relapse during the entire treatment period (15% missing data). Most clinical effectiveness measures, MSSS, MSIS-29 and SDMT showed statistically significant improvement between baseline and 132 months (p<0.05). Over the entire observation time, 125 SAEs had been reported to the Swedish MPA including 9 cases (2 fatal) of progressive multifocal leukoencephalopathy (PML) of which 8 occurred between 2008 and 2012, and one in 2018.Conclusions: NTZ is generally well tolerated with sustained effectiveness regarding cognitive, physical and psychological measures, as well as relapse-control. Introduction of JCV testing has led to fewer treated JCV+ patients, which likely explains a drastic drop in number of reported cases of PML.

- Background: Alemtuzumab (ALZ) is a modulatory drug for patients with relapsing-remitting multiple sclerosis (RRMS). Post-marketing surveillance is important to assess the long term safety and effectiveness in a real-world setting. ALZ has therefore been included into the Swedish post-market surveillance study “Immunomodulation and Multiple Sclerosis Epidemiology Study 3” (IMSE 3) upon launch in Sweden (March 2014).Objective: To follow up the effectiveness and long-term safety of ALZ in a real-world setting.Methods: Swedish MS patients are registered into the nationwide Swedish Neuro Registry (NeuroReg). IMSE 3 includes patients starting ALZ treatment. Adverse events (AEs) and clinical meas-ures; Extended Disability Status Scale (EDSS), Multiple Sclerosis Severity Scale (MSSS), Symbol Digit Modalities Test (SDMT), Multiple Sclerosis Impact Scale (MSIS-29), European Quality of Life - 5 Dimension Test (EQ-5D) and Visual Analogue Scale (VAS) are obtained from NeuroReg. The Wilcoxon signed-rank test was used to assess changes in effectiveness.Results: 110 patients (60% female; 95% RRMS) have been included in IMSE 3 between March 2014 and April 2018. Mean age at treatment start was 34 years and mean treatment duration was 28 months. Most patients (40%) switched from natalizumab and 14% were treatment naïve. 103 patients were currently treated with ALZ at cut-off date and 97 patients had been treated for at least 12 months. Seven patients had discontinued ALZ treatment, of which five patients switched to another disease modifying therapy, one patient died in association with the first ALZ treatment cycle due to fulminant viral hepatitis and one patient had no treatment registered after ALZ discontinuation. In total, 20 AEs were reported to the Swedish Medical Products Agency; 13 events were classified as non-serious. In patients treated at least 12 months significant improvements were seen for EDSS (2.0±1.4 to 1.6±1.3, n=67), MSSS (3.4±2.6 to 2.6±2.3, n=58), MSIS-29 Physical (22.9±21.0 to 17.5±18.0, n=83), VAS (66.9±22.0 to 73.7±18.5, n=68) and EQ-5D (0.7±0.3 to 0.8±0.3, n=74). MSIS-29 Psychological and SDMT did not improve significantly.Conclusions: NeuroReg functions well as a post-marketing drug surveillance platform, providing data regarding drug effectiveness and AEs. A longer follow-up period is needed to evaluate the real-world effectiveness and safety of ALZ.

- Background: Fingolimod (FGL) is an oral therapy for patients with relapsing-remitting multiple sclerosis (RRMS) and the efficacy has been shown in phase II and III studies. However; long-term surveillance and safety is important, therefore FGL is included in the Swedish “Immunomodulation and Multiple Sclerosis Epidemiology Study 2” (IMSE 2).Objective: To follow up the effectiveness and long-term safety of FGL in a real-world setting.Methods: Swedish MS patients are registered into the nationwide Swedish Neuro Registry (NeuroReg). IMSE 2 includes data of adverse events (AEs) and clinical measures; Extended Disability Status Scale (EDSS), Multiple Sclerosis Severity Scale (MSSS), Symbol Digit Modalities Test (SDMT), Multiple Sclerosis Impact Scale (MSIS-29), European Quality of Life - 5 Dimension Test (EQ-5D) and Visual Analogue Scale (VAS), obtained from NeuroReg.Results: From September 2011 until April 2018, 1617 patients (67% female; 91% RRMS) were included in IMSE 2. At treatment start 38 patients were ≤20 years (yr), 308 aged 21-30 yr and 1271 aged >30 yr. Mean treatment duration was 34 months. 852 patients were currently treated with FGL at cut-off date and 1230 patients had been treated for at least 12 months. In total, 39% switched treatment from interferons or glatiramer acetate, 26% from natalizumab and 5% from dimethyl fumarate or teriflunomide. 803 patients have discontinued FGL at some point, mainly due to lack of effect (43%) or AEs (34%), most patients switched to rituximab after FGL discontinuation. Relapses were reduced from 281 to 87/1000 patient years (PY) when comparing before and during FGL treatment. In patients aged ≤20 yr, 21-30 yr and >30 yr relapses were reduced from 694 to 144/1000 PY, 455 to 129/1000 PY and 258 to 77/1000 PY, respectively. After 12 months significant improvements were seen in EQ-5D (0.7 to 0.8, n=752), MSSS (3.1 to 2.9, n=410), MSIS-29 Physical (21.1 to 20.0 n=812), MSIS-29 Psychological (29.2 to 24.9, n=812), SDMT (54.3 to 57.0, n=751) and VAS (70.9 to 72.8, n=692). When analysing age groups separately significant improvements were seen in MSSS, SDMT, and MSIS-29 Psychological in patients aged 21-30 yr and >30 yr. EQ-5D, VAS and MSIS-29 Physical significantly improved in patients aged >30 yr.Conclusions: FGL is a generally well-tolerated drug that reduces the clinical activity in MS patients. NeuroReg functions well as a drug surveillance platform, enabling monitoring of long-term effectiveness and AEs.
