METHODS: We reviewed the records of 74 patients with scleroderma without pulmonary arterial hypertension followed at our institution. Patient demographics and PFT parameters (FVC, TLC, and DLCO) were noted. Patients’ chest HRCT scans were graded by a radiologist for ILD by a HRCT fibrosis score, calculated by estimating the percentage of parenchymal involvement in three zones (upper, middle, lower) of each lung, with a score of 100 representing normal and a score of 400 representing severe fibrosis. PFT variables were recorded as percent predicted (%) and expressed as mean ± SD. Pearson’s test for linear correlation was used to determine correlation of fibrosis score with FVC, TLC and DLCO.
