OBJECTIVE: Lichen planus (LP) is one of the chronic infl ammatory diseases. Epicardial fatty tissue (EFT) is the adipose tissue in which pro-infl ammatory and pro-atherogenic hormones and cytokines are secreted. We planned to investigate the predictive value of EFT in LP patients by evaluating together with Fibrinogen to albumin ratio (FAR) other infl ammation markers. MATERIALS AND METHODS: A total of 53 consecutive LP patients and 57 healthy controls were enrolled in this single-center, prospective, case-control study. Demographic data were recorded; blood tests were obtained from both groups. Then, EFT thickness was measured by echocardiography. RESULTS: Fibrinogen, FAR, neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio, and EFT thickness were higher in LP patients (p < 0.05, for all). EFT was positively correlated with FAR (r = 0.306, p = 0.001), NLR (r = 0.240, p = 0.011), and PLR (r = 0.297, p = 0.002). ROC analysis indicated that FAR could predict LP with a sensitivity of 83 % and a specifi city of 44 %; NLR could predict LP with a sensitivity of 80 % and a specifi city of 46 %; EFT could predict LP with a sensitivity of 79 % and a specifi city of 54 %. In the binary logistic regression analysis NLR, FAR, and EFT were found to be independent predictors of LP. CONCLUSION: We found a relationship between LP and FAR together with other infl ammation parameters NLR, and PLR. We demonstrated for the fi rst time that FAR, NLR and EFT were independent predictors of LP. Also, there was a signifi cant relationship between these parameters and EFT (Tab. 4, Fig. 1, Ref. 30).
