- In many species, the offspring of related parents suffer reduced reproductive success, a phenomenon known as inbreeding depression. In humans, the importance of this effect has remained unclear, partly because reproduction between close relatives is both rare and frequently associated with confounding social factors. Here, using genomic inbreeding coefficients (FROH) for >1.4 million individuals, we show that FROH is significantly associated (p < 0.0005) with apparently deleterious changes in 32 out of 100 traits analysed. These changes are associated with runs of homozygosity (ROH), but not with common variant homozygosity, suggesting that genetic variants associated with inbreeding depression are predominantly rare. The effect on fertility is striking: FROH equivalent to the offspring of first cousins is associated with a 55% decrease [95% CI 44–66%] in the odds of having children. Finally, the effects of FROH are confirmed within full-sibling pairs, where the variation in FROH is independent of all environmental confounding.

Tidskriftsartikel (refereegranskat)abstract
- Background: Child health is a key priority on the global health agenda, yet the provision of essential and emergency surgery in children is patchy in resource-poor regions. This study was aimed to determine the mortality risk for emergency abdominal paediatric surgery in low-income countries globally.Methods: Multicentre, international, prospective, cohort study. Self-selected surgical units performing emergency abdominal surgery submitted prespecified data for consecutive children aged <16 years during a 2-week period between July and December 2014. The United Nation's Human Development Index (HDI) was used to stratify countries. The main outcome measure was 30-day postoperative mortality, analysed by multilevel logistic regression.Results: This study included 1409 patients from 253 centres in 43 countries; 282 children were under 2 years of age. Among them, 265 (18.8%) were from low-HDI, 450 (31.9%) from middle-HDI and 694 (49.3%) from high-HDI countries. The most common operations performed were appendectomy, small bowel resection, pyloromyotomy and correction of intussusception. After adjustment for patient and hospital risk factors, child mortality at 30 days was significantly higher in low-HDI (adjusted OR 7.14 (95% CI 2.52 to 20.23), p<0.001) and middle-HDI (4.42 (1.44 to 13.56), p=0.009) countries compared with high-HDI countries, translating to 40 excess deaths per 1000 procedures performed.Conclusions: Adjusted mortality in children following emergency abdominal surgery may be as high as 7 times greater in low-HDI and middle-HDI countries compared with high-HDI countries. Effective provision of emergency essential surgery should be a key priority for global child health agendas.

- Educational attainment is strongly influenced by social and other environmental factors, but genetic factors are estimated to account for at least 20% of the variation across individuals. Here we report the results of a genome-wide association study (GWAS) for educational attainment that extends our earlier discovery sample of 101,069 individuals to 293,723 individuals, and a replication study in an independent sample of 111,349 individuals from the UK Biobank. We identify 74 genome-wide significant loci associated with the number of years of schooling completed. Single-nucleotide polymorphisms associated with educational attainment are disproportionately found in genomic regions regulating gene expression in the fetal brain. Candidate genes are preferentially expressed in neural tissue, especially during the prenatal period, and enriched for biological pathways involved in neural development. Our findings demonstrate that, even for a behavioural phenotype that is mostly environmentally determined, a well-powered GWAS identifies replicable associated genetic variants that suggest biologically relevant pathways. Because educational attainment is measured in large numbers of individuals, it will continue to be useful as a proxy phenotype in efforts to characterize the genetic influences of related phenotypes, including cognition and neuropsychiatric diseases.

Genome-wide association study of eosinophilic granulomatosis with polyangiitis reveals genomic loci stratified by ANCA status

Tidskriftsartikel (refereegranskat)abstract
- Eosinophilic granulomatosis with polyangiitis (EGPA) is a rare inflammatory disease of unknown cause. 30% of patients have anti-neutrophil cytoplasmic antibodies (ANCA) specific for myeloperoxidase (MPO). Here, we describe a genome-wide association study in 676 EGPA cases and 6809 controls, that identifies 4 EGPA-associated loci through conventional case-control analysis, and 4 additional associations through a conditional false discovery rate approach. Many variants are also associated with asthma and six are associated with eosinophil count in the general population. Through Mendelian randomisation, we show that a primary tendency to eosinophilia contributes to EGPA susceptibility. Stratification by ANCA reveals that EGPA comprises two genetically and clinically distinct syndromes. MPO+ ANCA EGPA is an eosinophilic autoimmune disease sharing certain clinical features and an HLA-DQ association with MPO+ ANCA-associated vasculitis, while ANCA-negative EGPA may instead have a mucosal/barrier dysfunction origin. Four candidate genes are targets of therapies in development, supporting their exploration in EGPA.

- Peatlands in the northern hemisphere have accumulated more atmospheric carbon (C) during the Holocene than any other terrestrial ecosystem, making peatlands long-term C sinks of global importance. Projected increases in nitrogen (N) deposition and temperature make future accumulation rates uncertain. Here, we assessed the impact of N deposition on peatland C sequestration potential by investigating the effects of experimental N addition on Sphagnum moss. We employed meta-regressions to the results of 107 field experiments, accounting for sampling dependence in the data. We found that high N loading (comprising N application rate, experiment duration, background N deposition) depressed Sphagnum production relative to untreated controls. The interactive effects of presence of competitive vascular plants and high tissue N concentrations indicated intensified biotic interactions and altered nutrient stochiometry as mechanisms underlying the detrimental N effects. Importantly, a higher summer temperature (mean for July) and increased annual precipitation intensified the negative effects of N. The temperature effect was comparable to an experimental application of almost 4 g N m(-2) yr(-1) for each 1 degrees C increase. Our results indicate that current rates of N deposition in a warmer environment will strongly inhibit C sequestration by Sphagnum-dominated vegetation.

- Peat bogs have accumulated more atmospheric carbon (C) than any other terrestrial ecosystem today. Most of this C is associated with peat moss (Sphagnum) litter. Atmospheric nitrogen (N) deposition can decrease Sphagnum production, compromising the C sequestration capacity of peat bogs. The mechanisms underlying the reduced production are uncertain, necessitating multifactorial experiments. We investigated whether glasshouse experiments are reliable proxies for field experiments for assessing interactions between N deposition and environment as controls on Sphagnum N concentration and production. We performed a meta-analysis over 115 glasshouse experiments and 107 field experiments. We found that glasshouse and field experiments gave similar qualitative and quantitative estimates of changes in Sphagnum N concentration in response to N application. However, glasshouse-based estimates of changes in production even qualitative assessments diverged from field experiments owing to a stronger N effect on production response in absence of vascular plants in the glasshouse, and a weaker N effect on production response in presence of vascular plants compared to field experiments. Thus, although we need glasshouse experiments to study how interacting environmental factors affect the response of Sphagnum to increased N deposition, we need field experiments to properly quantify these effects.

Tidskriftsartikel (refereegranskat)abstract
- BackgroundPrimary care is a critical partner for antimicrobial stewardship efforts given its high human antibiotic usage. Peer comparison audit and feedback (A & F) is often used to reduce inappropriate antibiotic prescribing. The design and implementation of A & F may impact its effectiveness. There are no best practice guidelines for peer comparison A & F in antibiotic prescribing in primary care.ObjectiveTo develop best practice guidelines for peer comparison A & F for antibiotic prescribing in primary care in high income countries by leveraging international expertise via the Joint Programming Initiative on Antimicrobial Resistance-Primary Care Antibiotic Audit and Feedback Network.MethodsWe used a modified Delphi process to achieve convergence of expert opinions on best practice statements for peer comparison A & F based on existing evidence and theory. Three rounds were performed, each with online surveys and virtual meetings to enable discussion and rating of each best practice statement. A five-point Likert scale was used to rate consensus with a median threshold score of 4 to indicate a consensus statement.ResultsThe final set of guidelines include 13 best practice statements in four categories: general considerations (n = 3), selecting feedback recipients (n = 1), data and indicator selection (n = 4), and feedback delivery (n = 5).ConclusionWe report an expert-derived best practice recommendations for designing and evaluating peer comparison A & F for antibiotic prescribing in primary care. These 13 statements can be used by A & F designers to optimize the impact of their quality improvement interventions, and improve antibiotic prescribing in primary care.

- Roskilde University (Denmark) hosted a November 2015 workshop, Environmental RiskAssessing and Managing Multiple Risks in a Changing World. This Focus article presents the consensus recommendations of 30 attendees from 9 countries regarding implementation of a common currency (ecosystem services) for holistic environmental risk assessment and management; improvements to risk assessment and management in a complex, human-modified, and changing world; appropriate development of protection goals in a 2-stage process; dealing with societal issues; risk-management information needs; conducting risk assessment of risk management; and development of adaptive and flexible regulatory systems. The authors encourage both cross-disciplinary and interdisciplinary approaches to address their 10 recommendations: 1) adopt ecosystem services as a common currency for risk assessment and management; 2) consider cumulative stressors (chemical and nonchemical) and determine which dominate to best manage and restore ecosystem services; 3) fully integrate risk managers and communities of interest into the risk-assessment process; 4) fully integrate risk assessors and communities of interest into the risk-management process; 5) consider socioeconomics and increased transparency in both risk assessment and risk management; 6) recognize the ethical rights of humans and ecosystems to an adequate level of protection; 7) determine relevant reference conditions and the proper ecological context for assessments in human-modified systems; 8) assess risks and benefits to humans and the ecosystem and consider unintended consequences of management actions; 9) avoid excessive conservatism or possible underprotection resulting from sole reliance on binary, numerical benchmarks; and 10) develop adaptive risk-management and regulatory goals based on ranges of uncertainty.

Transancestral mapping and genetic load in systemic lupus erythematosus

Tidskriftsartikel (refereegranskat)abstract
- Systemic lupus erythematosus (SLE) is an autoimmune disease with marked gender and ethnic disparities. We report a large transancestral association study of SLE using Immunochip genotype data from 27,574 individuals of European (EA), African (AA) and Hispanic Amerindian (HA) ancestry. We identify 58 distinct non-HLA regions in EA, 9 in AA and 16 in HA (similar to 50% of these regions have multiple independent associations); these include 24 novel SLE regions (P < 5 x 10(-8)), refined association signals in established regions, extended associations to additional ancestries, and a disentangled complex HLA multigenic effect. The risk allele count (genetic load) exhibits an accelerating pattern of SLE risk, leading us to posit a cumulative hit hypothesis for autoimmune disease. Comparing results across the three ancestries identifies both ancestry-dependent and ancestry-independent contributions to SLE risk. Our results are consistent with the unique and complex histories of the populations sampled, and collectively help clarify the genetic architecture and ethnic disparities in SLE.

- 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.

- STUDY QUESTION Can use of a commercially available time-lapse algorithm for Day 5 blastocyst selection improve pregnancy rates compared with morphology alone? SUMMARY ANSWER The use of a time-lapse selection model to choose blastocysts for fresh single embryo transfer on Day 5 did not improve ongoing pregnancy rate compared to morphology alone. WHAT IS KNOWN ALREADY Evidence from time-lapse monitoring suggests correlations between timing of key developmental events and embryo viability. No good quality evidence exists to support improved pregnancy rates following time-lapse selection. STUDY DESIGN, SIZE, DURATION A prospective multicenter randomized controlled trial including 776 randomized patients was performed between 2018 and 2021. Patients with at least two good quality blastocysts on Day 5 were allocated by a computer randomization program in a proportion of 1:1 into either the control group, whereby single blastocysts were selected for transfer by morphology alone, or the intervention group whereby final selection was decided by a commercially available time-lapse model. The embryologists at the time of blastocyst morphological scoring were blinded to which study group the patients would be randomized, and the physician and patients were blind to which group they were allocated until after the primary outcome was known. The primary outcome was number of ongoing pregnancies in the two groups. PARTICIPANTS/MATERIALS, SETTING, METHODS From 10 Nordic IVF clinics, 776 patients with a minimum of two good quality blastocysts on Day 5 (D5) were randomized into one of the two study groups. A commercial time-lapse model decided the final selection of blastocysts for 387 patients in the intervention (time-lapse) group, and blastocysts with the highest morphological score were transferred for 389 patients in the control group. Only single embryo transfers in fresh cycles were performed. MAIN RESULTS AND THE ROLE OF CHANCE In the full analysis set, the ongoing pregnancy rate for the time-lapse group was 47.4% (175/369) and 48.1% (181/376) in the control group. No statistically significant difference was found between the two groups: mean difference -0.7% (95% CI -8.2, 6.7, P = 0.90). Pregnancy rate (60.2% versus 59.0%, mean difference 1.1%, 95% CI -6.2, 8.4, P = 0.81) and early pregnancy loss (21.2% versus 18.5%, mean difference 2.7%, 95% CI -5.2, 10.6, P = 0.55) were the same for the time-lapse and the control group. Subgroup analyses showed that patient and treatment characteristics did not significantly affect the commercial time-lapse model D5 performance. In the time-lapse group, the choice of best blastocyst changed on 42% of occasions (154/369, 95% CI 36.9, 47.2) after the algorithm was applied, and this rate was similar for most treatment clinics. LIMITATIONS, REASONS FOR CAUTION During 2020, the patient recruitment rate slowed down at participating clinics owing to coronavirus disease-19 restrictions, so the target sample size was not achieved as planned and it was decided to stop the trial prematurely. The study only investigated embryo selection at the blastocyst stage on D5 in fresh IVF transfer cycles. In addition, only blastocysts of good morphological quality were considered for transfer, limiting the number of embryos for selection in both groups: also, it could be argued that this manual preselection of blastocysts limits the theoretical selection power of time-lapse, as well as restricting the results mainly to a good prognosis patient group. Most patients were aimed for blastocyst stage transfer when a minimum of five zygotes were available for extended culture. Finally, the primary clinical outcome evaluated was pregnancy to only 6-8 weeks. WIDER IMPLICATIONS OF THE FINDINGS The study suggests that time-lapse selection with a commercially available time-lapse model does not increase chance of ongoing pregnancy after single blastocyst transfer on Day 5 compared to morphology alone. STUDY FUNDING/COMPETING INTEREST(S) The study was financed by a grant from the Swedish state under the ALF-agreement between the Swedish government and the county councils (ALFGBG-723141). Vitrolife supported the study with embryo culture dishes and culture media. During the study period, T.H. changed his employment from Livio AB to Vitrolife AB. All other authors have no conflicts of interests to disclose. DATE OF FIRST PATIENT'S ENROLMENT 11 June 2018.

- 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.

- Background: Teriflunomid (TFM) 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 4” (IMSE 4) in order to surveille and determine the long-term safety and effectiveness in a real-world setting.Objectives: To follow-up the long-term safety and effectiveness of TFM in a real-world setting.Methods: MS patients are registered into the nationwide Swedish Neuro Registry (NeuroReg) in Sweden. 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. 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.

Sediment reworking by the burrowing polychaete Hediste diversicolor modulated by environmental and biological factors across the temperate North Atlantic. A tribute to Gaston Desrosiers
- 2021

Tidskriftsartikel (refereegranskat)abstract
- Particle mixing and irrigation of the seabed by benthic fauna (bioturbation) have major impacts on ecosystem functions such as remineralization of organic matter and sediment-water exchange. As a tribute to Prof. Gaston Desrosiers by the Nereis Park association, eighteen laboratories carried out a collaborative experiment to acquire a global snapshot of particle reworking by the polychaete Hediste diversicolor at 16 sites surrounding the Northern Atlantic. Organisms and soft sediments were collected during May - July at different geographical locations and, using a common laboratory protocol, particulate fluorescent tracers (`luminophores') were used to quantify particle transport over a 10-day period. Particle mixing was quantified using the maximum penetration depth of tracers (MPD), particle diffusive coefficients (D-b), and non-local transport coefficients (r). Non-local coefficients (reflecting centimeter scale transport steps) ranged from 0.4 to 15 yr(-1), and were not correlated across sites with any measured biological (biomass, biovolume) or environmental parameters (temperature, grain size, organic matter). Maximum penetration depths (MPD) averaged similar to 10.7 cm (6.5-14.5 cm), and were similar to the global average bioturbation depth inferred from short-lived radiochemical tracers. MPD was also not correlated with measures of size (individual biomass), but increased with grain size and decreased with temperature. Bio-diffusion (D-b) correlated inversely with individual biomass (size) and directly with temperature over the environmental range (Q(10) similar to 1.7; 5-21 degrees C). The transport data were comparable in magnitude to rates reported for localized H. diversicolor populations of similar size, and confirmed some but not all correlations between sediment reworking and biological and environmental variables found in previous studies. The results imply that measures of particle reworking activities of a species from a single location can be generally extrapolated to different populations at similar conditions.

Response of marine benthic fauna to thin-layer capping with activated carbon in a large-scale field experiment in the Grenland fjords, Norway
- 2017
-
Ingår i: Environmental Science and Pollution Research. - : Springer Science and Business Media LLC. - 0944-1344 .- 1614-7499. ; 24:16, s. 14218-14233

Tidskriftsartikel (refereegranskat)abstract
- A field experiment with thin-layer capping was conducted in the Grenland fjords, Norway, for remediation in situ of mercury and dioxin-contaminated sediments. Experimental fields at 30 and 95 m depth were capped with (i) powdered activated carbon (AC) mixed with clay (AC+clay), (ii) clay, and (iii) crushed limestone. Ecological effects on the benthic community and species-feeding guilds were studied 1 and 14 months after capping, and a total of 158 species were included in the analyses. The results show that clay and limestone had only minor effects on the benthic community, while AC+clay caused severe perturbations. AC+clay reduced the abundance, biomass, and number of species by up to 90% at both 30 and 95 m depth, and few indications of recovery were found during the period of this investigation. The negative effects of AC+clay were observed on a wide range of species with different feeding strategies, although the suspension feeding brittle star Amphiura filiformis was particularly affected. Even though activated carbon is effective in reducing sediment-to-water fluxes of dioxins and other organic pollutants, this study shows that capping with powdered AC can lead to substantial disturbances to the benthic community.

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Background: Natalizumab (NTZ) is a highly effective disease modulatory treatment for relapsing-remitting multiple sclerosis (RRMS). Post-marketing surveillance is important for determination of long-term safety and effectiveness in a real-world setting. To this end the “Immunomodulation and Multiple Sclerosis Epidemiology Study 1” (IMSE 1) was initiated upon NTZ launch in Sweden (Aug 2006).Objective: To follow-up the long-term safety and effectiveness of NTZ in a real-world setting.Methods: In Sweden MS patients are registered in the nationwide Swedish Neuro Registry (NeuroReg). IMSE 1 includes patients starting NTZ treatment and data is collected from NeuroReg. Adverse events (AEs), JC-virus status (JCV) and clinical effectiveness measures are registered prospectively.Results: 3052 patients (72% female; 82% RRMS; mean age at treatment start 36 years; mean treatment duration 45.9 months) have been included in IMSE 1 from August 2006 until April 2018. A total of 1234 RRMS patients where included year ≥2011 (JCV test introduction) and had information on JCV (482 anti-JCV anti-bodies (JCV+), 752 JCV negative (JCV-)). 691 of these patients were currently treated with NZT at cutoff date, 88 (13%) of which were JCV+ with a mean JCV index at 1.1±1.1. A total of 612/1234 (49%) discontinued NTZ treatment at some time point of which 266/403 (66%) JCV+ discontinued due to JCV+. JCV- patients mainly discontinued due to pregnancy/planning pregnancy (78/209, 37%) and other reasons (57/209, 27%). The one and two-year drug survival rate was 79% and 45% for JCV+ and 90% and 82% for JCV-. The overall drug survival rate was 16% for JCV+ and 72% for JCV-. In patients with continuous NTZ treatment for ≥2 years (n=738), long lasting stabilization of disease activity was observed. From year 2006 until cutoff, 96 Serious AEs had been reported to the Swedish MPA and included 8 cases (1 fatal) of progressive multifocal leukoencephalopathy (PML), reported between 2008 and 2012. A total of 14 patients have died during or within 6 months after NTZ discontinuation, as reported in NeuroReg. None were reported to be associated to NTZ.Conclusions: NeuroReg functions well as a post-marketing drug surveillance platform, providing long-term data on drug effects and AEs. NTZ is generally well tolerated with sustained effective-ness. The introduction of JCV testing has led to fewer treated JCV+ patients, which likely explains a reduced incidence of PML.

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- 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 reduces the tendency to deteriorate disabilities. However, the long-term safety is important, therefore PegINF is included in the Swedish “Immunomodulation and Multiple Sclerosis Epidemiology Study 6” (IMSE 6). Which characterizes the real-world profile of PegIFN, including efficacy, safety, tolerability and patient outcome parameters.Objectives: To follow-up the long-term safety and effectiveness of PegIFN in a real-world setting.Methods: Approximately 60 collaborating neurology clinics continuously recruited PegIFN patients and documented clinical and demographic data in the nationwide Swedish Neuro Registry (NeuroReg). Data were obtained from NeuroReg between June 2015 and April 2018 for the IMSE 6 study.Results: A total of 324 patients (78% female; 88% RRMS; mean age at treatments start 43 years) were followed up to 34 months (mean 15 months) with 26% treatment naïve and 49% switched from other injectables. Mean duration from initial symptom(s) to treatment start was 114 months, and 69 months from MS diagnosis to treatment start. In total, 169 patients discontinued for vari-ous reasons (60% adverse events, 24% lack of effect) and switched mainly to rituximab (63 patients, 37%). The discontinuation rate at 12 months was 42.6%. Relapses before treatment were reduced from 207 to 130/1000 patient years during treatment. With 55% having no relapse and 9% having 1 relapse during treatment period (35% missing data). After 12 months, all clinical effectiveness measures (Extended Disability Status Scale (EDSS), Multiple Sclerosis Severity Scale (MSSS), Multiple Sclerosis Impact Scale (MSIS-29), European Quality of Life - 5-Dimension test (EQ-5D), Visual Analogue Score (VAS), and the mean Symbol Digit Modalities Test (SDMT)) remained stable. A total number of 9 adverse events (6 serious: 1 gastrointestinal disorder, 2 general disorder and administrations site, 2 skin, 1 reproductive) were reported to Swedish Medical Product Agency (MPA).Conclusions: NeuroReg proves to function well as a post-marketing drug surveillance platform, providing data regarding drug effectiveness and AEs. This real-world study presentation from IMSE 6 shows a stable efficacy and safety profile in long-term clinical use.

- 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.

Tidskriftsartikel (refereegranskat)abstract
- Background Antibiotic overuse and misuse in primary care are common, highlighting the importance of antimicrobial stewardship (AMS) efforts in this setting. Audit and feedback (A&F) interventions can improve professional practice and performance in some settings. Objectives and methods To leverage the expertise from international members of the Joint Programming Initiative on Antimicrobial Resistance - Primary care Antibiotic Audit and feedback Network (JPIAMR-PAAN). Network members all have experience of designing and delivering A&F interventions to reduce inappropriate antibiotic prescribing in primary care settings. We aim to introduce the network and explore ongoing A&F activities in member regions. An online survey was administered to all network members to collect regional information. Results Fifteen respondents from 11 countries provided information on A&F activities in their country, and national/regional antibiotic stewardship programmes or policies. Most countries use electronic medical records as the primary data source, antibiotic appropriateness as the main outcome of feedback, and target GPs as the prescribers of interest. Funding sources varied across countries, which could influence the frequency and quality of A&F interventions. Nine out of 11 countries reported having a national antibiotic stewardship programme or policy, which aim to provide systematic support to ongoing AMS efforts and aid sustainability. Conclusions The survey identified gaps and opportunities for AMS efforts that include A&F across member countries in Europe, Canada and Australia. JPIAMR-PAAN will continue to leverage its members to produce best practice resources and toolkits for antibiotic A&F interventions in primary care settings and identify research priorities.

Impaired benthic macrofauna function 4 years after sediment capping with activated carbon in the Grenland fjords, Norway
- 2021

Tidskriftsartikel (refereegranskat)abstract
- The sediments in the Grenland fjords in southern Norway are heavily contaminated by large emissions of dioxins and mercury from historic industrial activities. As a possible in situ remediation option, thin-layer sediment surface capping with powdered activated carbon (AC) mixed with clay was applied at two large test sites (10,000 and 40,000 m(2)) at 30-m and 95-m depths, respectively, in 2009. This paper describes the long-term biological effects of the AC treatment on marine benthic communities up to 4 years after treatment. Our results show that the capping with AC strongly reduced the benthic species diversity, abundance, and biomass by up to 90%. Vital functions in the benthic ecosystem such as particle reworking and bioirrigation of the sediment were also reduced, analyzed by using novel bioturbation and bioirrigation indices (BPc, BIPc, and IPc). Much of the initial effects observed after 1 and 14 months were still present after 49 months, indicating that the effects are long-lasting. These long-lasting negative ecological effects should be carefully considered before decisions are made on sediment remediation with powdered AC, especially in large areas, since important ecosystem functions can be impaired.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: The optimal management of patients with breast cancer (BC) requires the expertise of specialists from different disciplines. This has led to the evolution of multidisciplinary teams (MDTs), allowing all key professionals to jointly discuss individual patients and to contribute independently to clinical decisions. Data regarding BC MDTs in different regions and countries are scarce.METHODS: The investigators of a large global phase III adjuvant BC trial being conducted by the Breast International Group were invited to respond to a questionnaire about the extent, structure, and function of BC MDTs.RESULTS: One hundred and fifty-two responses from 39 countries were received, and remarkable differences were noted in different geographic regions. Sixty-five percent of the respondents from eastern Europe, 63% from western Europe, 35% from Asia, and 25% from South America declared that MDT was a mandatory part of BC care in their country. Ninety percent of the respondents from Europe stated their MDTs met weekly, compared with only half of the respondents from Asia.CONCLUSION: This survey is perhaps the first large-scale effort to collect information regarding BC MDTs from different parts of the world and provides objective information of frequency, composition, function, and working mechanism of BC MDTs.

- 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.

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.

Tidskriftsartikel (refereegranskat)abstract
- The spatiotemporal pattern of cerebral amyloid deposition, detectable as light microscopically recognizable aggregates in an 'amyloid only' transgenic mouse model of Alzheimer's disease, B6C3Tg(APPswe,PSEN1dE9)85Dbo/Mmjax, is reported for the first time in this strain. Monoclonal and polyclonal antibodies were used to detect amyloid deposition immunohistochemically in brains collected from these mice at 3-12 months of age. Amyloid aggregates (20-200 mu m) were first found in serial, whole coronal sections of brain at 4 months of age and these increased progressively, plateauing at 11-12 months. They were most abundant in the cerebral cortices, hippocampus, olfactory bulbs, some white matter tracts and the cerebellar molecular layer; no amyloid aggregates were found in the midbrain, brainstem or spinal cord, or in an equivalent number of brains from wild-type mice. Since the parahippocampal gyrus is severely damaged early in the clinical course of human Alzheimer's disease, amyloid aggregates were also assessed in this brain region and a similar temporal course of amyloid deposition was observed. Moreover, in this gyrus, the amount of aggregated amyloid showed no significant difference between left- and right-sided gyri. However, the polyclonal antibody detected a significantly greater amyloid burden than the monoclonal antibody at 3-10 months of age and the reverse was seen at 11-12 months of age. The pattern of amyloid deposition in the parahippocampal gyrus also resembled that found in the entire brain over time, when the latter was quantified by the colour deconvolution method, suggesting that this gyrus is a good marker for more widely distributed cerebral amyloid deposition. This neuropathological characterization will permit better use of the B6C3-Tg(APPswe,PSEN1dE9)85Dbo/Mmjax transgenic mouse strain in future studies of Alzheimer's disease pathogenesis, prevention and treatment.

- 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.
