    BACKGROUND: Preeclampsia and eclampsia, which are the most frequent hypertensive disorders in pregnancy, are associated with renal involvements. We aimed to assess the time trend in blood pressure levels, renal function and proteinuria after delivery, and investigate their determinants in Cameroonian women with severe preeclampsia and eclampsia. METHODS: This was a prospective cohort study involving 54 women with severe preeclampsia and eclampsia, conducted between July 2010 and February 2012 at the central maternity unit of the Yaounde Central Hospital. Clinical and laboratory parameters were recorded from day-1 to 6months after delivery. Mixed-linear and logistic regression models were used to relate baseline and within follow-up levels of covariates, with changes in blood pressure levels, renal function and proteinuria, as well as persisting hypertension, renal failure and proteinuria. RESULTS: During follow-up, a significant improvement was observed in blood pressure, renal function and proteinuria (all p<0.002). Thirteen (24.1%) patients with renal failure at delivery recovered completely within six weeks. Twenty-six (48.1%), 17 (31.5%) and 1 (1.8%) patients had persisting proteinuria at 6weeks, 3months and 6months post-delivery, respectively. Corresponding figures for persisting hypertension were 23 (42.6%), 15 (27.8%) and 8 (14.8%). Advanced age, higher body mass index, low gestational age at delivery, low fetal birth weight, and proteinuria at delivery were the main risk factors for persisting hypertension at 3months, meanwhile low fetal birth weight, severe preeclampsia and proteinuria at delivery were correlated with persisting proteinuria at 3months. Advanced age and higher body mass index were the only determinants of the composite outcome of persisting hypertension or proteinuria at three and six months. CONCLUSION: Hypertension and proteinuria are very common beyond the postpartum period in Cameroonian women with severe preeclampsia and eclampsia. Long-term follow-up of these women will help preventing and controlling related complications.

    Prevalence and risk factors of chronic kidney disease in urban adult Cameroonians according to three common estimators of the glomerular filtration rate: a cross-sectional study

    BACKGROUND: Chronic kidney disease (CKD) is a major threat to the health of people of African ancestry. We assessed the prevalence and risk factors of CKD among adults in urban Cameroon. METHODS: This was a cross-sectional study of two months duration (March to April 2013) conducted at the Cite des Palmiers health district in the Littoral region of Cameroon. A multistage cluster sampling approach was applied. Estimated glomerular filtration rate (eGFR) was based on the Cockcroft-Gault (CG), the four-variable Modification of Diet in Renal Disease (MDRD) study and Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equations. Logistic regression models were used to investigate the predictors of CKD. RESULTS: In the 500 participants with a mean age of 45.3+/-13.2years included, we observed a high prevalence of overweight and obesity (60.4%), hypertension (38.6%) and diabetes (2.8%). The mean eGFR was 93.7+/-24.9, 97.8+/-24.9 and 99.2+/-31.4ml/min respectively with the MDRD, CG and CKD-EPI equations. The prevalence of albuminuria was 7.2% while the prevalence of decreased GFR (eGFR<60ml/min) and CKD (any albuminuria and/or eGFR<60ml/min) was 4.4 and 11% with MDRD, 5.4 and 14.2% with CG, and 8.8 and 10% with CKD-EPI. In age and sex adjusted logistic regression models, advanced age, known hypertension and diabetes mellitus, increasing body mass index and overweight/obesity were the predictors of albuminuria, decreased GFR and CKD according to various estimators. CONCLUSION: There is a high prevalence of CKD in urban adults Cameroonian, driven essentially by the commonest risk factors for CKD.
