Mean Platelet Volume in the Diagnosis and Prognosis of Crimean–Congo Hemorrhagic Fever

Introduction: Crimean–Congo hemorrhagic fever (CCHF) is a viral tick-borne zoonosis, which is a severe illness, causing hemorrhages in humans. Mean platelet volume (MPV) is used as a surrogate marker of platelet function and has been shown to be a sign of inflammation. The objective of the present study is to examine the association between MPV and CCHF. We also aimed to investigate the association between MPV and coagulopathy markers in the mortality rates and prognosis of patients with CCHF. Patients and Methods: Ninety-three patients with CCHF were enrolled retrospectively into the study and 15 of them were excluded according to the exclusion criteria. Twenty-five healthy individuals were included as a control group which was age and gender matched with CCHF patients. We compared the levels of MPV between the patient and the control groups. We also compared the coagulopathy markers of fatal CCHF patients (n = 9) with nonfatal cases (n = 69). Results: Platelet counts were significantly lower in the CCHF group. Levels of international normalized ratio (INR), prothrombin time (PT), and activated partial thromboplastin time (aPTT) were significantly higher in CCHF group (P < .001,
