The Role of Urinary Calcium and Chitotriosidase in a Cohort of Chronic Sarcoidosis Patients

Abstract

Calcium metabolism alteration, particularly hypercalciuria, was observed in a significant percentage of patients of sarcoidosis. Urinary calcium was correlated with clinical status, DLCO, and serum CTO activity, suggesting its potential role as a biomarker of the activity and severity of sarcoidosis.
