- Multiple sclerosis (MS) is associated with considerable morbidity and serious disability, but little is known of the long-term impact of the disease on work ability. Objectives: To assess sick leave (short-term absence) and disability pension (long-term absence) before and after diagnosis of MS. Methods: Patients with MS in Sweden were identified in a nationwide disease-specific register and matched with general population controls. Sick leave and disability pension were measured before and after index (i.e. the MS diagnosis date). Results: The final sample comprised 6092 patients and 60,345 controls (mean age 39 years; 70% female). The mean annual prevalence of sick leave ranged from 12% the first year after index to 23% after 11 years among patients and from 13% to 13% among controls. Corresponding estimates for disability pension were 12% and 55% for patients and 7% and 9% for controls. Significant differences in sick leave were observed up to 15 years before index and 3 years for disability pension. Conclusion: Patients with MS in Sweden have elevated levels of sick leave and disability pension up to 15 years before disease diagnosis. Our results highlight the burden of disease on affected patients and society and underscore the substantial unmet medical need.

- Benign multiple sclerosis (BMS) is often defined by the Expanded Disability Status Scale (EDSS) score of ≤3.0 after ≥15 years of disease duration. This classification’s clinical relevance remains unclear as benign patients may suffer other impairments and advance towards a progressive course, prompting our objective to holistically investigate factors associated with BMS and its long-term prognosis.MethodsBenign cases were identified in the Swedish Multiple Sclerosis registry. Baseline clinical data, demographic features and influence of multiple sclerosis (MS) major risk alleles on likelihood of benign course were investigated. Physical disability (EDSS), cognitive function (Symbol Digit Modalities Test; SDMT) and self-reported and socioeconomic differences between benign and non-benign patients were evaluated using generalised estimation equations models.Results11222 patients (2420 benign/8802 non-benign) were included. Benign patients were more likely to be female and younger at MS onset, have fewer relapses within the first two and 5 years from onset and fully recover from the first relapse (p<0.001). No association between human leucocyte antigen (HLA) DRB1*15:01 carriership (OR: 0.97, 95% CI: 0.86 to 1.09) or HLA-A*02:01 lacking (OR: 0.99, 95% CI: 0.87 to 1.11) and benign/non-benign was found. Non-benign patients accumulated an extra 0.04 (95% CI 0.03 to 0.04, p<0.001) EDSS score/year, lost an extra 0.3 (95% CI − 0.39 to − 0.18, p<0.001) SDMT score/year and deteriorated faster in self-reported impact and socioeconomic measures (p<0.001).ConclusionPatients with BMS have a better disease course as they progress more slowly at the group level in all respects. Lack of an association with major genetic risk factors indicates that MS course is most likely influenced by either environmental factor(s) or genetic factors outside the HLA region.

- Background Early treatment with disease modifying therapies (DMTs) for multiple sclerosis (MS) has been associated with lower disability progression; the aim was to explore its association with cost of illness (COI) in MS. Methods All people with relapsing-remitting MS in the Swedish MS register, aged 20-57 years and receiving their first MS DMT in 2006-2009, were followed in nationwide registers for 8 years. Healthcare costs (in- and outpatient healthcare, DMTs and other prescribed drugs), and productivity losses (sickness absence and disability pension) of individuals receiving therapy in <= 6 months after diagnosis (early treatment group) were compared to those receiving therapy >6 months (late treatment group). Using Poisson regressions, the mean COI per patient per year, and per group, was estimated, adjusted for disability progression. Results The early treatment group comprised 74% of the 1562 individuals included in the study. The early treatment group had lower productivity losses over time. Both groups had similar healthcare costs, which first increased and then decreased over time. Conclusions Early DMT in MS could result in lower productivity losses possibly through maintained work capacity. COI serves as an objective measure showing the advantage of early vs. late treatment initiation in MS.

- Early initiation of disease-modifying treatment (DMT) is associated with better disability outcomes in multiple sclerosis (MS). However, little is known of how treatment decisions affect socio-economic outcomes. Objective To estimate the long-term impact of early initiation of DMT on the income of MS patients. Methods In total, 3610 MS patients were included in this register-based cohort study. We measured the association between the time to treatment and the outcome, defined as time from treatment initiation to a 95% decrease in annual earnings compared to each patient´s baseline level. Additionally, the association between time to treatment and increase of social benefits (sickness absence, disability pension) was investigated. A Cox model was adjusted for sex, onset age, education, family situation, country of birth, living area, and disability. Results MS patients initiating treatment later had a higher risk of reaching the outcome- those who started treatment after 2 years from MS onset lost 95% of their earnings sooner (HR, 1.19; 95% CI, 1.04–1.37). Furthermore, risk to receive an annual compensation of SEK 100,000 (≈EUR 10,500) was higher for the delayed treatment group. Conclusion Early treatment initiation in MS is associated with better socioeconomic outcome, adding to previous studies showing benefits regarding disability.

- ObjectivesDisease-modifying therapies (DMTs) can slow disease progression in multiple sclerosis (MS). The objective of this study was to explore the cost-of-illness (COI) progression among newly diagnosed people with MS in relation to the first DMT received.Design and settingA cohort study using data from nationwide registers in Sweden.ParticipantsPeople with MS (PwMS) in Sweden first diagnosed in 2006-2015, when aged 20-55, receiving first-line therapy with interferons (IFN), glatiramer acetate (GA) or natalizumab (NAT). They were followed up through 2016.Outcome measuresOutcomes (in Euros, euro) were: (1) secondary healthcare costs: specialised outpatient and inpatient care including out-of-pocket expenditure, DMTs including hospital-administered MS therapies, and prescribed drugs, and (2) productivity losses: sickness absence and disability pension. Descriptive statistics and Poisson regression were computed, adjusting for disability progression using the Expanded Disability Status Scale.Results3673 newly diagnosed PwMS who were treated with IFN (N=2696), GA (N=441) or NAT (N=536) were identified. Healthcare costs were similar for the INF and GA groups, while the NAT group had higher costs (p value<0.05), owing to DMT and outpatient costs. IFN had lower productivity losses than NAT and GA (p value>0.05), driven by fewer sickness absence days. NAT had a trend towards lower disability pension costs compared with GA (p value>0.05).ConclusionsSimilar trends over time for healthcare costs and productivity losses were identified across the DMT subgroups. PwMS on NAT maintained their work capacity for a longer time compared with those on GA, potentially leading to lower disability pension costs over time. COI serves as an objective measure to explore the importance of DMTs in maintaining low levels of progression of MS over time.

- Multiple sclerosis (MS) is a challenging and disabling condition, predominantly affecting individuals in early adulthood. MS affects the physical, cognitive, and mental health of persons suffering from the disease as well as having a great impact on their financial status and quality of life. However, there is a lack of systematic approach toward assessing the socioeconomic consequences of MS. Our objective was to systematically review analytical observational studies investigating the socioeconomic consequences in persons with MS with different levels of physical disability and cognitive function. We conducted a systematic review on socioeconomic consequences of MS with a focus on employment-, income-, work ability-, and relationship-related outcomes in persons with MS with special focus on disability and cognition. Additionally, the educational characteristics were examined. From 4,957 studies identified, 214 were assessed for eligibility and a total of 19 studies were included in this qualitative assessment; 21 different outcomes were identified. All identified studies reported higher unemployment, higher early retirement, and higher risk of unemployment in relation to higher physical disability. Also, cognitive function was found to be a predictor of employment (unemployment). The studies pointed out significant correlations between greater disability and lower earnings and higher income from benefits. A study found the same correlation in relation to cognitive function. The studies reported higher work disability in relation to higher physical disability and lower cognitive function. In conclusion, this systematic review summarizes the pronounced differences in various socioeconomic outcomes between patients with MS with regards to their physical disability and cognitive function. In addition, we identified a lack of studies with longitudinal design in this field that can provide more robust estimates with covariate adjustments, such as disease modifying treatments.
