Opioids, SSRIs and Steroids Increase Fracture Risk in RA

Analysis of a large US observational rheumatoid arthritis (RA) patients finds that opioids, SSRIs and glucocorticoids were associated with increased risk of fracture in RA, whereas statins and TNFi had a decreased vertebral fracture risk.

FORWARD is a longitudinal observational RA registry that assessed patients for osteoporosis-related site fractures (vertebra, hip, forearm and humerus) between  2001 and 2017. Fracture Risk Assessment Tool (FRAX) scores estimating for 10-year major osteoporotic fractures were calculated. Cox proportional hazard models stratified by FRAX were used to adjust for confounders.

A total of 11 412 patients, with a median followup of 3 years, experienced 914 fractures.

A significantly increased adjusted fracture risk was seen for:

  • any dose glucocorticoids ≥3 months
    • <7.5 mg/day HR 1.26 (1.07 to 1.48)
    • ≥7.5 mg/day 1.57 (1.27 to 1.94))
  • opioids (for weak: 1.37 (1.18 to 1.59); strong: 1.53 (1.24 to 1.88))
    • Fracture risk with opioids increased within 1 month of use (1.66 (1.36 to 2.04))
  • selective serotonin reuptake inhibitors (SSRIs) (1.37 (1.15 to 1.63)).
    • with SSRIs >3 months of use (1.25 (1.01 to 1.55)).

Statins (0.77 (0.62 to 0.96)) and TNFi (0.72 (0.54 to 0.97)) were associated with reduction in vertebral fracture risk only. PPIs and other psychotropic medications were not associated with increased fracture risk.

Two vs. Four Weeks of Antibiotic Therapy in Septic Arthritis

A prospective trial has shown that 2 weeks of antibiotic therapy is as effective as 4 weeks of antibiotic therapy, with similar outcomes but shorter hospital stays.

This Swiss study was a prospective, unblinded, randomised, non-inferiority study comparing either 2 or 4 weeks of antibiotic therapy after surgical drainage of native joint bacterial arthritis in adults. 

Bimekizumab Add-on Therapy in Rheumatoid Arthritis

Bimekizumab is a dual inhibitor of IL-17A and IL-17F that has been shown to be effective in psoriasis and psoriatic arthritis. A proof-of-concept study shows that giving bimekizumab to rheumatoid arthritis patients not adequately controlled by certolizumab pegol resulted in a rapid decrease in disease activity achieved after 12 weeks of treatment. These findings are novel as anti-IL-17 monoclonal antibody therapy has previously been shown to be ineffective in RA.

74 Percent of Rheumatoid Arthritis Patients Dissatisfied with Treatment

CreakyJoints has completed a 258 patient survey showing that nearly three-fourths of people with rheumatoid arthritis (RA) have expressed dissatisfaction with their treatments, including conventional (csDMARDs) and biologic Disease Modifying Antirheumatic Drugs (bDMARDs).

RA Women are Less Likely to Breastfeed

A large pregnancy registry has published their results showing rheumatoid arthritis (RA) patients who become pregnant are less likely to breastfeed compared to non-RA women from the general population, with many women stopping breastfeeding so that they could start medication, even though many of these meds are safe to use during lactation.

Respiratory Risks Not Increased in RA Patients with COPD

An insurance claims based study of RA patients with COPD shows that biologics do not have an increased rate of respiratory events compared to those on conventional DMARDs. A real world cohort of RA patients with COPD was drawn from US-based MarketScan databases. Patients on biologic DMARDs and/or targeted synthetic DMARDs (tsDMARDs) were propensity matched to those on conventional synthetic DMARDs (csDMARDs).
