title: [The evaluation of early pulmonary involvement with high resolution computerized tomography in asymptomatic and non-smoker patients with rheumatoid arthritis].
abstract: To investigate pulmonary involvement by high resolution computerized tomography (HRCT) in patients with rheumatoid arthritis (RA) who are asymptomatic and lifelong non-smoker. Twenty-five patients with RA who are asymptomatic and lifelong non-smoker were included in the study. After clinical and laboratory investigations, plain chest X-rays, pulmonary function tests (PFT) and HRCT were performed. End expiratory HRCT slices were obtained for air trapping. Chest X-ray, PFT and HRCT findings showed 12%, 16%, 48% abnormalities, respectively. Interstitial involvement was the most common finding on HRCT (36%) and followed by air trapping (20%). Bronchiectasis, pulmonary nodule, and pleural disease were seen in 16%, 12%, and 12% of patients, respectively. None of patients had emphysema and honeycomb pattern. There was no statistically significant correlation between HRCT findings and disease activity criteria, RF positivity, PFT results and duration of the disease. Our study shows that pulmonary involvement is not always together with respiratory symptoms and impaired pulmonary function in patients with RA. New studies are needed which investigating the effects of radiologically detected lung involvement on prediction of survival and treatment choice in asymptomatic and nonsmoker RA patients.
