Abstract

Background and objective: Thrombocytopenia, described as a platelet count of less than 150,000 mm3, is a common diagnosis during the period of pregnancy, existing in 7–12% of pregnancies. Mild thrombocytopenia occurs if platelet counts are less than 100,000 mm3, while moderate thrombocytopenia is between 50,000 and 100,000 mm3, and severe thrombocytopenia occurs if platelet counts are less than 50,000 mm3. It could be connected to physiologic changes or pathological diseases; some of them have an impact on pregnancy and may offer a serious risk to both the mother and the unborn child. This study sought to estimate the proportions of the underlying causes as well as the prevalence of thrombocytopenia among pregnant women visiting the antenatal care center in Erbil.

Methods: A cross-sectional study was performed in a maternity teaching hospital in Erbil city, Kurdistan region, Iraq. A convenience sample of 600 pregnant women was used from 28 weeks to 40 weeks of gestation. Over a period of 1 year, starting in January 2021 and ending in December 2021.

Results: The prevalence of thrombocytopenia among the 600 cases was 24.8%, but the majority (75.2%) had a normal platelet count; the degrees of thrombocytopenia were severe in 1.8% of the cases, mild in 8.3%, and moderate in 14.7% of the cases.

Conclusion: A statistically significant association between preeclampsia and HELLP syndrome has been reported as a serious condition that leads to thrombocytopenia. High serum albumin levels in pregnant women related to hypertension had a major impact on the number of platelet counts and should be considered a severe disease.
