Epidemiology and maternal prognosis of hypertension disorders of pregnancy in French Guiana

Abstract

Background: Hypertensive disorders of pregnancy (HDP) are responsible for high maternal mortality and morbidity worldwide.

Objective: Our primary objective was to report the epidemiological and clinical features of HDP in Cayenne General Hospital. Our secondary objectives were to search for factors associated to preeclampsia (PE) and to severe PE in patients with HDP.

Methods: Our study was observational and non-interventional. It was conducted over 4-month period (January to April 2019) in the Obstetrics and Gynaecology Unit of the Cayenne General Hospital. We included all pregnant women after 20 weeks of gestation (WG), who gave birth and who presented HDP and/or PE.

Results: During the study period 1243 patients gave birth in our unit. Among them, 156 were diagnosed with HDP (12.6%). The median age was 33 years (IQR 28 - 38 years). The most frequent medical histories were diabetes (27.5%) and chronic hypertension (23.5%). The socioeconomic status was low in 31% of patients. Ninety-four patients (61.4%) developed PE with a severe form in 80.9% of cases. HELLP syndrome was diagnosed in 6.5% and nephropathy in 3.3% of cases. Delivery was by cesarean in 49.7% of cases. The median gestational age at delivery was 37 WG (IQR: 35-39). Multivariate analysis showed no independent factors associated with the occurrence of PE or severe PE in patients with HDP.

Conclusion: Our study shows a high prevalence of PE in patients with HDP. Hospitalization and repeated clinical evaluation are needed to screen for women exposed to develop PE or severe PE.
