    • 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.

  • The impact of bariatric surgery on disease activity and progression of multiple sclerosis : A nationwide matched cohort study
  • 2022
  • Ingår i: Multiple Sclerosis Journal. - : Sage Publications. - 1352-4585 .- 1477-0970. ; 28:13, s. 2099-2105
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: Surgical outcomes in patients with multiple sclerosis (MS) following metabolic surgery appear to be similar compared to those of the general bariatric population.OBJECTIVE: To study the impact of metabolic surgery on the clinical course of MS.METHODS: Using data from the Scandinavian Obesity Surgery Registry and the Swedish Multiple Sclerosis register, we compared disease outcomes in 122 cases of MS who had undergone metabolic surgery with those of 122 cases of MS without surgery, matched by a two-staged Propensity score match, including age at disease onset, sex, MS phenotype, body mass index, and preoperative severity of MS as measured by the Expanded Disability Status Scale.RESULTS: The time to 6-month confirmed disability progression during the first five years postbaseline was shorter among the surgical patients (hazard ratio (HR) = 2.31, 95% confidence interval (CI) = 1.09-4.90; p = 0.03). No differences were observed regarding postoperative annual relapse rate (p = 0.24) or time to first postoperative relapse (p = 0.52).CONCLUSION: Although metabolic surgery appears to be a safe and efficient treatment of obesity in patients with MS, the clinical course of the disease might be negatively affected. Long-term nutritional follow-up after surgery and supplementation maintenance are crucial, particularly among those with preoperative deficits.

  • Aggressive multiple sclerosis (2): Treatment
  • 2020
  • Ingår i: Multiple sclerosis (Houndmills, Basingstoke, England). - : SAGE Publications. - 1477-0970 .- 1352-4585. ; 26:9, s. 1045-1063
  • Tidskriftsartikel (refereegranskat)abstract
    • The natural history of multiple sclerosis (MS) is highly heterogeneous. A subgroup of patients has what might be termed aggressive MS. These patients may have frequent, severe relapses with incomplete recovery and are at risk of developing greater and permanent disability at the earlier stages of the disease. Their therapeutic window of opportunity may be narrow, and while it is generally considered that they will benefit from starting early with a highly efficacious treatment, a unified definition of aggressive MS does not exist and data on its treatment are largely lacking. Based on discussions at an international focused workshop sponsored by the European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS), we review our current knowledge about treatment of individuals with aggressive MS. We analyse the available evidence, identify gaps in knowledge and suggest future research needed to fill those gaps. A companion paper details the difficulties in developing a consensus about what defines aggressive MS.

  • Evidence of diffuse cerebellar neuroinflammation in multiple sclerosis by 11C-PBR28 MR-PET
  • 2020
  • Ingår i: Multiple sclerosis (Houndmills, Basingstoke, England). - : SAGE Publications. - 1477-0970 .- 1352-4585. ; 26:6, s. 668-678

    • Activated microglia, which can be detected in vivo by 11C-PBR28 positron emission tomography (PET), represent a main component of MS pathology in the brain. Their role in the cerebellum is still unexplored, although cerebellar involvement in MS is frequent and accounts for disability progression. Objectives: We aimed at characterizing cerebellar neuroinflammation in MS patients compared to healthy subjects by combining 11C-PBR28 MRI-Positron Emission Tomography (MR-PET) with 7 Tesla (T) MRI and assessing its relationship with brain neuroinflammation and clinical outcome measures. Methods: Twenty-eight MS patients and 16 healthy controls underwent 11C-PBR28 MR-PET to measure microglia activation in normal appearing cerebellum and lesions segmented from 7 T scans. Patients were evaluated using the Expanded Disability Status Scale and Symbol Digit Modalities Test. 11C-PBR28 binding was assessed in regions of interest using 60–90 minutes standardized uptake values normalized by a pseudo-reference region in the brain normal appearing white matter. Multilinear regression was used to compare tracer uptake in MS and healthy controls and assess correlations with clinical scores. Results: In all cerebellar regions examined, MS patients showed abnormally increased tracer uptake, which correlated with cognitive and neurological disability. Conclusion: Neuroinflammation is widespread in the cerebellum of patients with MS and related to neurological disability and cognitive impairment.

  • Depression and multiple sclerosis: A bidirectional Mendelian randomisation study
  • 2021
  • Ingår i: Multiple sclerosis (Houndmills, Basingstoke, England). - : SAGE Publications. - 1477-0970 .- 1352-4585. ; 27:11, s. 1799-1802
  • Tidskriftsartikel (refereegranskat)abstract
    • Depression is common in multiple sclerosis (MS); however, the underlying mechanism for the relationship remains unknown. In this study, we examined a putative causal relationship between depression and MS using a bidirectional Mendelian randomisation (MR) framework. Using the latest genome-wide association study data available, 168 non–major histocompatibility complex (MHC) independent variants associated with MS and 96 independent genetic variants associated with depression susceptibility were used. Maximum likelihood, weighted median, inverse variance weighted method and MR-Egger regression analyses were performed. There was no significant risk for the development of MS in persons carrying variants associated with depression or for risk of depression in individuals who are genetically susceptible to MS.

  • Leptin levels are associated with multiple sclerosis risk
  • 2021
  • Ingår i: Multiple Sclerosis Journal. - : SAGE Publications. - 1352-4585 .- 1477-0970. ; 27:1, s. 19-27
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Obesity early in life has been linked to increased risk of developing multiple sclerosis (MS). Leptin and insulin are both associated with obesity, making them suitable candidates for investigating this connection. Objective: To determine if leptin and insulin are risk factors for relapsing-remitting multiple sclerosis (RRMS). Methods: In this nested case-control study using blood samples from Swedish biobanks, we compared concentrations of leptin and insulin in 649 individuals who later developed RRMS with 649 controls matched for biobank, sex, age and date of sampling. Only pre-symptomatically drawn samples from individuals below the age of 40 years were included. Conditional logistic regression was performed on z-scored values to calculate odds ratios (ORs) with 95% confidence intervals (CIs). Results: A 1-unit leptin z-score increase was associated with increased risk of MS in individuals younger than 20 years (OR = 1.4, 95% CI = 1.1-1.9) and in all men (OR = 1.4, 95% CI = 1.0-2.0). In contrast, for women aged 30-39 years, there was a lower risk of MS with increased leptin levels (OR = 0.74, 95% CI = 0.54-1.0) when adjusting for insulin levels. Conclusion: We show that the pro-inflammatory adipokine leptin is a risk factor for MS among young individuals.

  • Trajectories of sickness absence and disability pension days among people with multiple sclerosis by type of occupation
  • 2022
  • Ingår i: Multiple sclerosis (Houndmills, Basingstoke, England). - : SAGE Publications. - 1477-0970 .- 1352-4585. ; 28:9, s. 1402-1413
  • Tidskriftsartikel (refereegranskat)abstract
    • Multiple sclerosis (MS) can impact working life, sickness absence (SA) and disability pension (DP). Different types of occupations involve different demands, which may be associated with trajectories of SA/DP among people with MS (PwMS). Objectives: To explore, among PwMS and references, if SA/DP differ according to type of occupation. Furthermore, to examine how trajectories of SA/DP days are associated with type of occupation among PwMS. Methods: A longitudinal nationwide Swedish register-based cohort study was conducted, including 6100 individuals with prevalent MS and 38,641 matched references from the population. Trajectories of SA/DP were identified with group-based trajectory modelling. Multinomial logistic regressions were estimated for associations between identified trajectories and occupations. Results: Increase of SA/DP over time was observed in all occupational groups, in both PwMS and references, with higher levels of SA/DP among PwMS. The lowest levels of SA/DP were observed among managers. Three trajectory groups of SA/DP were identified: Persistently Low (55.2%), Moderate Increasing (31.9%) and High Increasing (12.8%). Managers and those working in Science & Technology, and Economics, Social & Cultural were more likely to belong to the Persistently Low group. Conclusion: Results suggest that type of occupation plays a role in the level and course of SA/DP.
