Objective. Interstitial lung disease (ILD) is a common extra-articular manifestation of rheumatoid arthritis (RA) and a significant cause of morbidity and mortality. The objective of this study was to define high-resolution chest CT (HRCT) and pulmonary function test (PFT) abnormalities capable of identifying asymptomatic, preclinical forms of RA-ILD that may represent precursors to more severe fibrotic lung disease.Methods. We analyzed chest HRCTs in consecutively enrolled RA patients and subsequently classified these individuals as RA-ILD or RA-no ILD based on the presence/absence of ground glass opacification, septal thickening, reticulation, traction bronchiectasis, and/or honeycombing. Coexisting PFT abnormalities (reductions in percent predicted FEV1, FVC, TLC, and/or DLCO) were also used to further characterize occult respiratory defects.Results. 61% (63/103) of RA patients were classified as RA-ILD based on HRCT and PFT abnormalities, while 39% (40/103) were designated as RA-no ILD. 57/63 RA-ILD patients lacked symptoms of significant dyspnea or cough at the time of HRCT and PFT assessment. Compared with RA-no ILD, RA-ILD patients were older and had longer disease duration, higher articular disease activity, and more significant PFT abnormalities.Conclusion. HRCT represents an effective tool to detect occult/asymptomatic ILD that is highly prevalent in our unselected, university-based cohort of RA patients.

We report a case of a 52-year-old woman with a 1-year history of rheumatoid arthritis-associated interstitial lung disease referred to hospital because of aggravated pulmonary symptoms in spite of intensive treatment including prednisone, azathioprine and triptergium glycoside. We subsequently initiated treatment with 25 mg of etanercept, subcutaneously injected twice weekly. Following 6 months of therapy with this agent, sustained improvement in dyspnea, cough was reported by the patient and respiratory function test showed marked improvement. The improvement was confirmed by reduced middle and lower lung markings on chest radiography and high-resolution CT scan. This report suggests etanercept may be effective in the treatment of rheumatoid arthritis-associated interstitial lung disease.

Abstract Background Interstitial lung disease (ILD) is a serious extra-articular manifestation of rheumatoid arthritis (RA). Risk factors include smoking, the presence of rheumatoid factor (RF) and anti-cyclic citrullinated peptide antibodies (CCP). Pulmonary function tests (PFT) show reduced carbon monoxide diffusion capacity (DLCO) early and reduced forced vital capacity (FVC) later in disease. HRCT is the gold standard diagnostic test while chest X-ray (CXR) has low sensitivity. PFT are routinely performed in the majority of RA patients at baseline at our tertiary centre. The aim of this study was to evaluate the frequency of abnormal PFT, specificity for ILD and influence on subsequent decision-making in patients newly diagnosed with RA. Methods A retrospective analysis was undertaken of patients with a new diagnosis of RA between January 2016 and December 2017. Patients meeting the ACR (2010) criteria for RA, with baseline PFT data available were included. Clinic letters and the hospital electronic records were used to obtain the data. Results 139 patients were included in the data analysis (Table 1). 23 patients had DLCO <70% predicted, while 7 patients had an FVC <80% predicted. Patients with abnormal PFT were more likely to be older, female, seropositive and to have smoked. Of the patients with DLCO <70%, CXR was abnormal in 6 patients with changes suggesting ILD in 2 patients. 13 patients had HRCT and 7/13 patients had evidence of ILD and 6/13 patients had significant emphysema on CXR or HRCT. 1 patient with DLCO of 82% had changes of ILD on a CT scan organised for another reason. Methotrexate was commenced in 19/23 patients with DLCO<70% and discontinued in 2 patients for respiratory reasons. Conclusion This evaluation suggests baseline PFT are more sensitive than baseline CXR in detecting ILD but that a DLCO <70% is not specific for this diagnosis. The abnormal PFT lead to HRCT being requested in 13/24 patients, of whom 7 had ILD which had not been identified by CXR in 5 patients. Baseline PFT are also useful as a reference point in patients who go on to develop respiratory symptoms at a later point in their illness. Disclosures A. Haque None. R. Kilding None. R. Smith None.
