Review Comparative Study
Opportunistic infections in patients with idiopathic inflammatory myopathies.
To describe the prevalence, clinical characteristics and risk factors of opportunistic infection (OI) in a cohort of patients with inflammatory myopathies, and compare mortality rates between those with and without OIs. ⋯ The prevalence of OI was 6.4% in our myositis cohort, higher than the rest of the inpatients of our hospital (1.7%; P < 0.01). High-dose glucocorticoids at disease onset and severe immunosuppression are the main factors implicated.
