Objective: To compare work loss after starting tumour necrosis factor inhibitors (TNFi), rituximab, abatacept or tocilizumab in patients with rheumatoid arthritis (RA).

Methods: We used data from the Swedish Rheumatology Quality Register to identify patients aged 19-62 years who were treated with TNFi (n=15 093), rituximab (n=2123), abatacept (n=1877) or tocilizumab (n=1720) between 2007 and 2020. Data on work loss (0-365 days per year) from sick leave and disability pension were retrieved from linkage to the Social Insurance Agency.

Objective: To compare the effectiveness of JAK inhibitors (JAKis) and biologic disease-modifying antirheumatic drugs (bDMARDs) on pain in patients with rheumatoid arthritis.

Methods: In this retrospective study, we investigated patients with a diagnosis of rheumatoid arthritis, starting treatment with a JAKi (n = 1,827), a tumor necrosis factor inhibitor (TNFi; n = 6,422), an interleukin-6 inhibitor (n = 887), abatacept (n = 1,102), or rituximab (n = 1,149) in 2017 to 2019, using data from several linked Swedish national registers. Differences in change in pain, assessed with a visual analogue scale (0-100 mm), from baseline to 3 months, as well as proportions of patients remaining on initial treatment with low pain (visual analogue scale pain <20) at 12 months, were compared between treatments.

Article Synopsis
  • The study investigates the familial connection between multiple sclerosis (MS) and immune mediated inflammatory diseases (IMIDs), given that even though MS is rare, IMIDs are more common and can impact public health.* -
  • Researchers analyzed data from almost 25,000 MS patients and over 250,000 controls, looking specifically at the odds of developing MS in individuals with first-degree relatives who have IMIDs.* -
  • Findings showed a slight increase in risk (OR of 1.09) for MS in families with a history of IMIDs and identified 18 IMID subtypes that are associated with MS, indicating potential shared genetic factors.*

Objective: To investigate the association between infections and disability worsening in people with multiple sclerosis (MS) treated with either B-cell depleting therapy (rituximab) or interferon-beta/glatiramer acetate (IFN/GA).

Methods: This cohort study spanned from 2000 to 2021, using data from the Swedish MS Registry linked to national health care registries, comprising 8,759 rituximab and 7,561 IFN/GA treatment episodes. The risk of hospital-treated infection was estimated using multivariable Cox models.
