Key clinical point: Rheumatoid arthritis (RA) increased the prevalence of interstitial lung abnormalities (ILA) in participants with a history of smoking, which in turn led to a significant increase in the mortality rate.
Major finding: ILA were ~4 times more prevalent in individuals with a history of smoking who did vs did not have RA (adjusted odds ratio 4.15; 95% CI 2.17-7.97). Among patients with RA and a record of smoking, mortality risk was ~3 times higher in those with ILA or indeterminate ILA findings vs those without ILA (adjusted hazard ratio 2.86; 95% CI 1.33-6.16).
Study details: This cross-sectional prospective study included participants with a current or past history of smoking from the COPDGene cohort, of whom 83 participants had RA and were compared with 8725 individuals without RA.
Disclosures: COPDGene was supported by the US National Heart, Lung, and Blood Institute and others. Several authors declared receiving consulting fees, grant support, research support, or having other ties with various sources.
