Rates found higher than for patients with lupus, rheumatoid arthritis, systemic sclerosis, or Sjogren’s syndrome

Among patients with systemic rheumatic diseases, the highest incidence of opportunistic infections was seen in those with polymyositis/dermatomyositis (PM/DM), Taiwanese researchers found.

In a nationally representative cohort study, the incidence rate for opportunistic infection was 61.3 (95% CI 56.6-66.2) per 1,000 person years for those with PM/DM, followed by 43.1 (95% CI 41.7-44.5) per 1,000 for those with lupus, according to Chun-Yu Lin, MD, of National Cheng Kung University in Tainan, and colleagues.
