Abstract

Background Sarcoidosis is a chronic disease of unknown etiology characterised by systemic non-caseating granulomas that can affect any organ in the body, especially the lungs and in which genetic and environmental factors are thought to play a role in its pathophysiology. Adipokines and myokines secreted from adipose and muscle tissue play a role in the pathogenesis or protection against many inflammatory and autoimmune diseases in which inflammation and immunity form the basis. In our study, we aimed to investigate the role of the irisin and adiponectin in sarcoidosis. Methods The study included 90 sarcoidosis patients and 86 healthy subjects. Adiponectin and irisin levels were analysed in addition to standard tests for diagnosis and follow-up of patients with sarcoidosis. The sensitivity and specificity of serum irisin levels for the diagnosis of sarcoidosis were evaluate dusing ROC analysis. Results Irisin levels were significantly lower in the patient group than in the control group (3.28-5.25, p < 0.001). There was no association between irisin levels and extrapulmonary involvement. The cut-off irisin value for the diagnosis of sarcoidosis was <= 4.2662 with 95% confidence interval, and the sensitivity and specificity were calculated as 84% and 55.8%, respectively. Conclusions To our knowledge, this is the first study to investigate irisin in sarcoidosis patients. Based on the available evidence, anti-inflammatory, anti-oxidant and anti-apoptocic effects of irisin may play a role in the pathophysiology of sarcoidosis. Although no significant difference was found in our study, we believe that a comprehensive evaluation of adiponectin in sarcoidosis is important.
