PROF. C. SEKADDE-KIGONDU (BSc, PhD) DEPARTMENT OF CLINICAL CHEMISTRY UNIVERSITY OF NAIROBI Degree: MMed Pathology 2004 ABSTRACT Background Pre-eclampsia is a severe complication of pregnancy, occurring in 2-6% of all pregnancies. Women who develop preeclampsia are at an increased risk of developing abruption-placenta, acute renal failure, cerebral hemorrhage, disseminated intravascular coagulopathy, pulmonary edema, circulatory collapse and eclampsia. Preeclampsia contributes to morbidity and mortality in both the mother and fetus. It is the major cause of premature delivery and prenatal death. It is responsible of a fifth to a third of all maternal deaths. Pre-eclampsia has been described as a “disease of theories”. It has been linked to placental dysfunction initiating the systemic vasospasm, ischaemia and thrombosis that eventually damages maternal organs and causes placental infarction, fetal morbidity and fetal death. Of late, there has been an increasing interest in possible link between infection-inflammation and endothelial dysfunction, and between endothelial dysfunction and preeclampsia. C-reactive protein (CRP) is a sensitive marker of systemic inflammation and therefore, will be raised in preeclampsia and can be used as a biologic marker of inflammation in pre-eclampsia. Currently, there is no biological marker for preeclampsia. The rationale of this study is the fact that preeclampsia is an important contributor to the maternal and fetal morbidity and mortality in our set-up. No studies have been done to investigate the role of infection/inflammation in the causation of preeclampsia locally. Objectives: The main objective of the study was to determine CRP levels in preeclamptic and non-preeclamptic patients and compare the levels in the two groups and then make relevant recommendations based on the study findings. Methods: This was a comparative descriptive study conducted at the KNH between January and May 2004. A total of 140, comprising 73 preeclamptic patients and 67 normotensive pregnant mothers were recruited for this study. Personal and medical data were obtained from each patient using a questionnaire. Blood was taken for CRP and urea estimation. Results: A total of 140, comprising of 73 preeclamptic and 67 non-preeclamptic patients were recruited. The mean age was similar in the two groups. Mean systolic and diastolic blood pressures were 150.3 mmHg and 97 mmHg for preeclamptic group and 120.8 mmHg and 73.7 mmHg for the non-preeclamptic group respectively. 82.1% of preeclamptic patients had oedema with an odds ratio of 13.7 and 95% confidence interval from 6.0 to 31.3 and p-value<0.001. Preeclamptics had higher levels of protein in urine (mean 1.6+) compared to the comparative group (mean 0.25+) (p<0.001). Preeclamptics had higher levels of urea (mean 5.29 mmol/l, p<0.001) than non-preeclamptics (mean 2.83 mmol/l). CRP levels were higher in preeclamptics (mean 71.1mg/l) than non-preeclamptics (mean 50.0mg/l) (p<0.001). Conclusion: CRP value is significantly higher in preeclampsia indicating an association between inflammation and preeclampsia. This supports the postulate that preeclampsia results from endothelial injury due to inflammation, among other theories.
