Extract
Rheumatoid arthritis (RA) is a common disease, characterised by an erosive and inflammatory synovitis, which affects 1% of the general population [1]. Interstitial lung disease is a frequent extra-articular manifestation of RA and causes significant morbidity and mortality [2]. While ILD in RA is common, our understanding of the pathogenesis of RA-ILD is limited [3]. There have been observations that certain subtypes of RA-ILD may be clinically similar to idiopathic pulmonary fibrosis (IPF) [4], a form of progressive ILD, histologically characterised by a usual interstitial pneumonia (UIP) pattern [5]. Recent work in the genetics of RA-ILD has uncovered shared genetic risk factors between RA-ILD and IPF [6–8], further supporting a possible connection between these two conditions.
