INTRODUCTIONHypertensive disorders of pregnancy and their complications rank as one of the major cause of maternal mortality and morbidity in the world. Amongst them, preeclampsia is emerging as one of the most common complication of pregnancy.Pre-eclampsia is a multi-system disorder of unknown aetiology, unique to pregnancy, with onset after 20 weeks of gestation.Although, the exact aetiology of preeclampsia is not yet known, many factors such as low education, prim parity, family history of hypertension, obesity, younger and advanced maternal age and malnourishment are proven as its risk factors and evidence suggests that various other factors like severe anemia could also be a risk factor for development of preeclampsia and that cannot be ignored.The uncertainty of cause of a disease of such common occurrence worldwide, make it to be more studied. Several studies have shown the association between severe anemia and preeclampsia and thus considers anemia as one of the main and treatable risk factor for preeclampsia.Anemia during pregnancy is a major public health problem especially in developing countries which itself increases the maternal mortality, in addition it further ABSTRACT Background: Preeclampsia is a leading cause of maternal and perinatal morbidity and mortality worldwide. This study aims to evaluate correlation of anemia with severe preeclampsia. Methods: It is a prospective case control study conducted in Sultania Zanana Hospital, Bhopal over one year period. Patients were grouped as cases (severe preeclampsia with severe anemia, n=180) and controls (severe preeclampsia with no/mild/moderate anemia, n=180). Collecting data were compared using the Pearson chi square, fisher's exact test and the independent t-test as appropriate. Logistic regression analysis was performed. Odds ratio (OR) and their corresponding 95% confidence intervals were calculated. Results: Higher incidence of maternal complications abruption (8.88% v/s 0.5%), ARF (2.2% v/s 0.5%), PPH (2.8%), pulmonary edema (5%), CCF (3.3%), HELLP (1.6%), CVA (1.1%), pulmonary embolism and DIC in 0.5% and maternal mortality seen in cases. Perinatal complications like pregnancy wastage (22.8% v/s 7.8%), IUGR (55.8% v/s 32%), early neonatal death (7.5% v/s 2.4%), NICU admission (31.3% v/s 20.7%) were more in cases. Conclusions: Perinatal and maternal complications are significantly associated with severity of anemia in preeclampsia women. Anemia being a easily detectable and modifiable risk factor, detection of anemia in early gestation can be a key to prevent or decrease the severity of preeclampsia.
