Pulmonary function was assessed in 23 patients with rheumatoid arthritis (RA) of at least 5 years duration and had no cardio-respiratory symptoms, normal chest examination, chest roentgenogram and EKG. Nine patients (39%) had defect in at least one of the lung function test parameter. Only one patients had mild reduction in diffusion capacity (DLCO) as the sole defect. This specific subgroup of patients had a higher incidence of abnormalities in their PFT and should have spirometry routinely in their follow up. Performing a more expensive test like DLCO may be unnecessary as a routine test and its use may be restricted to follow up patients in whom specific therapy has been instituted.
