Familial Mediterranean Fever (FMF) is an autoinflammatory disease. Prolidase is a specific imidodipeptidase that plays a role in collagen degradation, and an important role in inflammation and wound healing. Hypoxia-inducible factor-1 alpha (HIF-1) is an important protein in the regulation of immunological response, hemostasis, vascularization. The aim of the study was to compare serum prolidase and HIF-1 alpha levels in patients with FMF in attack-free period and healthy control group. Methods. Between August 2017 and December 2017, sixty patients diagnosed with FMF according to the criteria of the Tel-hashomer and admitted to Sivas Cumhuriyet University Medical Faculty, Internal Medicine Rheumatology Department and sixty healthy volunteers were enrolled in the study. Results. Median serum prolidase levels were 72.1 (25.1-114.9) ng/ml in FMF group and 30.7 (21.3-86.2) ng/mL in healthy control (HC) group (p = 0.018). ROC analysis showed that the sensitivity was 65% and the specificity was 68.3% at serum prolidase levels 54.03 ng/mL (p < 0.05). The median serum levels of HIF-1 alpha in the FMF group was 482.0 (292.0-3967.0) pg/mL and 632.0 (362.0-927.0) pg/mL in the HC group (p > 0.05). There was no significant correlation between laboratory findings, sex, age, and prolidase (p > 0.05). Conclusion. Serum prolidase enzyme levels in FMF patients with attack-free period were significantly higher than in the HC group. However, the role of prolidase and HIF1-alpha in the FMF disease needs to be clarified with more extensive and comprehensive studies.en10.2478/rjim-2019-0025info:eu-repo/semantics/openAccessFamilial Mediterranean Fever (FMF)prolidaseHIF-1 alphaArticle5813327318464282-s2.0-85081944054Q3WOS:000519292900005N/A
