Cardiometabolic and Thrombotic Risk Profile in Women Undergoing Oocyte Donation for Assisted Reproduction.

ABSTRACT

Background: The last two decades have seen a growing number of pregnancies in women who needed the donation of oocytes. With oocyte donation pregnancies, studies on obstetric outcomes among these women revealed an increased incidence of pre-eclampsia and pregnancy-induced hypertension. Furthermore, several studies have found a higher incidence of low birth weight, preterm birth, and delivery by cesarean section in oocyte donation rather than in women subjected to assisted reproduction techniques (ART) with autologous oocytes. Numerous studies have also shown a deep connection between cardiovascular and thrombotic risk factors and adverse pregnancy outcomes. In this setting, to strictly assess the preconceptional risk for women who undergo egg donation to achieve pregnancy, the aim of our study is to draw a detailed assessment of the vascular risk profile of patients with gamete donation ART indications through the evaluation of comorbidities and cardiometabolic and thrombophilic markers Materials and Methods: Patients undergoing ART with oocyte or sperm donation or double donation of gametes underwent a careful clinical assessment through a detailed personal and family anamnesis and they were evaluated for cardiometabolic and thrombophilic profile. Clinical and demographic characteristics, comorbidities, and biohumoral parameters were collected. The study was approved by the Regional Ethical Committee(Em 2018-017 CINECA 10189). Results: We evaluated 525 women. Around 73.1% were >40 years and 35% of them were older than 45 years. There was a high prevalence of dyslipidemias (58.1%), smoking habit (24.6%), a body mass index >25 in 28.6% of patients, a high abdominal circumference in 58.1% of cases, a prevalence of acquired thrombophilia in about 7% and hereditary of 19.2%. Around 39.2% of patients had total cholesterol >200 mg/dL, 19.5% had high-density lipoprotein <48 mg/dL and 43.6% had low-density lipoprotein >115 mg/dL, and 6.9% had triglyceride values >150 mg/dL. Conclusions: A careful assessment of the preconceptional status of patients undergoing ART programs with oocyte donation can be highly recommended.
