Popis: To evaluate the distribution of circulating immune cell subsets in peripheral blood of patients with sarcoidosis and investigate if there is an association with an underlying cardiac involvement.Eighty-five newly diagnosed treatment-naïve patients with sarcoidosis (50 women) were included in the study. All patients underwent a thorough cardiac investigation, including cardiac magnetic resonance imaging (CMR). Of all patients, 19 (23.53%) had myocardial involvement, and the NK subpopulation in these patients in peripheral blood was significantly decreased compared to patients without (n = 63, p = 0.001 and p = 0.003 respectively). The absolute number of NKT cells (CD3+CD16/56We found that low NK cell count in peripheral blood of patients with sarcoidosis is associated with cardiac involvement, and the number of NK-T cells correlates with CMR findings indicative of myocardial inflammation. This finding might have a potential clinical application in detecting clinically silent cardiac involvement in sarcoidosis and may also suggest potential targets for therapeutic interventions.
