Can circulating interleukin-18 differentiate between sarcoidosis and idiopathic pulmonary fibrosis?

Abstract

As to the levels of IL-18 in serum and BALF, there were differences between sarcoidosis and IPF indicating a different role of IL-18 in the pathogenesis of these diseases. Measurement of circulating IL-18 might have a potential of clinical utility in the differential diagnosis of sarcoidosis versus IPF.
