The role of omentin in early pregnancy losses

Abstract

Abstract This prospective case-control study aimed to investigate the role of omentin, an anti-inflammatory adipokine in early pregnancy losses. The study comprised 47 women with spontaneous miscarriage at a gestational age of 8–12\u2009weeks and 36 healthy pregnant women, matched for age, body mass index and gestational age, gravdity and parity. A significant negative correlation was determined between plasma omentin concentrations and body weight (r=\u2009−0.242, p\u2009=\u2009.027) and gestational age (r=\u2009−0.249, p\u2009=\u2009.023). Although not statistically, the women with spontaneous miscarriage had higher plasma concentrations of omentin compared to those with healthy pregnancies (7.798\u2009±\u20093.453\u2009ng/ml vs. 7.200\u2009±\u20093.442\u2009ng/ml, p\u2009=\u2009.435). This finding might support the hypothesis that increased inflammation plays a role in the etiopathogenesis of early pregnancy losses. These results revealed the potential use of omentin to predict unhealthy pregnancies. Impact statement What is already known on the subject of the paper? The exact mechanism of early pregnancy loss with euploid foetal karyotype has not been elucidated yet. An alteration in the physiological inflammatory response of pregnancy might be one of the mechanisms responsible for miscarriage. What does this study add? To the best of our knowledge, this is the first study to investigate the role of omentin in early pregnancy loss. The results obtained from this current study could be used to clarify the relationship between inflammatory processes and miscarriage. What are the implications for clinical practice and/or further research? Identification of the role of omentin in the process of early pregnancy losses would be helpful in order to design further studies to determine the feasibility of using omentin as a serum marker to predict the risk of miscarriage in early pregnancies. Additionally, understanding of the etiopathogenesis of early pregnancy losses with euploid karyotype will give a lead to further researches which could focus on exploring new interventions to detect and treat altered inflammation in early pregnancies.
