Risk factors for eclampsia in pregnant women with preeclampsia and positive neurosensory signs
Journal Title: Turkish Journal of Obstetrics and Gynecology - Year 2018, Vol 15, Issue 4
Abstract
Objective: In Morocco, eclampsia remains the second major cause of maternal mortality. Conventionally, patients with preeclampsia and neurosensory signs (NSS) (e.g., headaches and hyperreflexia) are considered at high risk of worsening and progressing to eclampsia. However, this specific population is heterogeneous in terms of eclampsia occurrence. We aimed to identify the risk factors for the development of eclampsia in women with preeclampsia presenting with NSS at admission. Materials and Methods: We performed a single-center, retrospective case-control study of patients with preeclampsia with positive NSS from January 1st, 2012 through December 31st, 2015, to investigate predictive factors for eclamptic seizures. The case patients were pregnant women with severe preeclampsia who had NSS before developing eclampsia. Control subjects were those with positive NSS without the development of seizures during their hospital stay. One hundred-thirty eight patients with eclampsia and 272 control patients were enrolled. Results: Univariate analysis revealed that eclampsia was more likely to develop in patients with the following risk factors: maternal age ≤25 years (χ2=9.58, p=0.002), primiparity (χ2=6.38, p=0.011), inadequate prenatal care (χ2=11.62, p=0.001), systolic hypertension ≥160 mmHg (χ2=15.31, p<0.001), diastolic hypertension ≥110 mmHg (χ2=5.7, p=0.017), generalized acute edema (χ2=14.66, p<0.001), hematocrit <35% (χ2=11.16, p=0.001), serum creatinine >100 μmol/L (χ2=13.46, p<0.001), asparate aminotransferase (AST) >70 IU/L (χ2=10.15, p=0.001), and thrombocytopenia (χ2=22.73, p<0.001). Additionally, independent predictive factors for eclampsia in multivariate analysis included inadequate prenatal care [odds ratio (OR), 8.96 [95% confidence interval (CI): 3.9-20.5], p<0.001), systolic blood pressure ≥160 mmHg (OR, 3.130 [95% CI: 1.342-7.305], p=0.008), thrombocytopenia with a platelet count <50.000 (OR, 13.106 [95% CI: 1.344-127.823], p=0.027), AST ≥70 IU (OR, 3.575 [95% CI: 1.313-9.736], p=0.007), and elevated liver enzymes level, and low platelet count (ELLP) syndrome, which is an incomplete variant of HELLP syndrome (H for hemolysis) (OR, 5.83 [95% CI: 2.43- 13.9], p<0.001). Conclusion: This work highlights two major risk factors in this patient population, inadequate prenatal care and ELLP syndrome, which can help in the early identification of patients at highest risk of developing eclampsia and guide preventive measures.
