Study of C-reactive Protein Levels in Hypertensive Disorders of Pregnancy

Introduction Globally, one of the main causes of maternal and perinatal deaths is hypertensive disorders of pregnancy (HDP). Preeclampsia is a pregnancy-specific syndrome characterized by high blood pressure and proteinuria after 20-week gestation. Women who develop preeclampsia are at increased risk for the development of many systemic complications. Materials and methods A cross-sectional study was conducted in the Department of Biochemistry, SHKM, Nuh, Haryana in collaboration with the Department of Obstetrics & Gynecology. 200 study subjects; Group 1: cases - 100 HDP, Group 2: controls - 100 age-matched normotensive pregnant women. The specimen of 3 mL venous blood was collected under aseptic precautions. The data was evaluated using statistical evaluation tools. Result Out of 200 subjects, mean C-reactive protein (CRP) levels were normal in three cases and 35 controls. Minor elevation of CRP was observed in 11 cases and 29 controls (very significant). Moderate elevation of CRP was observed in 61 cases and 36 controls (highly significant). Marked elevation of CRP was observed in 25 cases. Mean CRP levels increased from preeclampsia without severe features (3.9 mg/dL), preeclampsia with severe features (5.2 mg/dL), and eclampsia (12.7 mg/dL) when compared with the respective control group (1.1 mg/dL, 1.16 mg/dL, and 1.2 mg/dL). Conclusion There is a highly significant association between CRP levels and HDP. Additionally, one useful indicator of the severity of preeclampsia is CRP, a measure of systemic inflammation. Elevated CRP levels in mild PE can be used as an indicator of the progress of the disease and early prevention can be done.
