Relationship between mean platelet volume and recurrent miscarriage: a preliminary study

INTRODUCTION: The aim of the study was to examine the relationship between mean platelet volume (MPV) and recurrent miscarriage in order to illuminate the etiopathogenesis of recurrent miscarriage. MATERIAL AND METHODS: We retrospectively investigated the data of 120 patients with unexplained recurrent miscarriage (group 1), and compared them with the data of 120 match-paired patients in the control group (group 2). The definition of recurrent miscarriage was accepted as two or more failed clinical pregnancies which were documented by ultrasonography or histopathologic examination. All patients in the recurrent miscarriage group were evaluated with diagnostic tests for the etiology of recurrent miscarriage. Total blood count parameters, including hemoglobin, mean corpuscular volume, red cell distribution width, white blood cells, platelets, and mean platelet volume, were compared. RESULTS: The average patient age at the time of examination was 29.07 ±2.81 years in group I and 28.53 ±3.5 years in group II (p > 0.05). Mean body mass index (BMI) was similar between group 1 and group 2, 22.54 ±3.17 and 22.99 ±2.38, respectively (p > 0.05). Mean hemoglobin, mean corpuscular volume, red cell distribution width, and white blood cell and platelet levels were similar in both groups (p > 0.05). Mean platelet volume levels were significantly higher in group I (9.45 ±1.09 fl) than in group II (7.63 ±0.52 fl) (p = 0.001). CONCLUSIONS: Higher MPV values in the study group suggest and support the importance of thromboembolic events in the etiology of recurrent miscarriage.
