X-ray, laboratory, and functional parallels in intrathoracic sarcoidosis

Abstract

Aim: to compare respiratory function and laboratory data with the radiographic stages of intrathoracic sarcoidosis. Subjects and methods. Three hundred and eleven patients (70.4% for women and 29.6% for men; mean age, 44.7±0.6 years) with histologically verified sarcoidosis underwent X-ray computed tomography, spirography, estimation of carbon monoxide diffusing capacity (DLCO), oxygen saturation, blood count and serum total calcium blood test. The patients were assigned according to sarcoidosis stages as follows: 3.9% with stage 0; 16.4% with stage I; 65.3% with stage II; 13.2% with stage III; 1.3% with stage IV, and 12.9% with Löfgren’s syndrome. Results. DLCO decreased together with an increasing sarcoidosis stage (
