Risk of pneumonia in individuals with rheumatoid arthritis: a nationwide cohort study.

ABSTRACT:

Background

Limited information is available on the influence of serologic status and different types of disease-modifying antirheumatic drugs (DMARDs) on risk of pneumonia. This study aimed to evaluate the risk of pneumonia according to rheumatoid arthritis (RA) seropositivity and type of DMARD.

Methods

This population-based cohort study enrolled individuals with RA (RA cohort, n=41 187) and 1:5 age-matched and sex-matched controls (n=205 935) between 2010 and 2017. Participants were followed from 1 year after RA diagnosis or matched control date until the first occurrence of pneumonia, pneumonia-related hospitalisation, death or 31 December 2019. The risks of pneumonia and related hospitalisation were evaluated according to serological status and type of DMARD.
