title: Relationship between high-resolution computed tomography findings and the Stoke index in patients with rheumatoid arthritis.
abstract: The aim of this study was to evaluate the relationship between high-resolution computed tomography (HRCT) findings and the Stoke index (SI) in patients with rheumatoid arthritis (RA). Forty RA patients (31 women, 9 men) were evaluated. All patients fulfilled the criteria proposed by the American College of Rheumatology. Clinical evaluation, haematological data, chest radiography, pulmonary function tests (PFTs) and HRCT were obtained in all patients. The SI was used to assess disease activity. In 17 (42.5%) patients, there were no signs of pulmonary involvement on HRCT; 23 (57.5%) of 40 patients had abnormal HRCT findings. Of 23 patients with HRCT abnormalities, six (two male, four female) had respiratory symptoms, four (one male, three female) had abnormalities on chest radiography and five (all female) had abnormalities on PFTs. There was no relationship between pulmonary changes observed on HRCT, clinical and laboratory disease activity parameters, chest X-ray and PFTs. There was no difference in the mean SI between patients included in the HRCT (+) and those included in the HRCT (-) groups. No significant correlations between the HRCT and the SI were seen. The main findings of this study are that HRCT can give useful information on RA-associated lung changes and that there was no relationship between the SI and the HRCT findings of patients with RA.
