RESUMO
Background The global burden of chronic kidney disease (CKD) has been on an alarming increase in the last two decades. The morbidity and mortality associated with CKD are even worse in Nigeria, like other developing countries, due to multiple socioeconomic and demographic factors in the country. CKD contributes to the increasing need for hospital admission. Hypertension and chronic glomerulonephritis have been the leading causes of CKD in Nigeria. However, diabetic nephropathy has recently gained more significance as a cause of CKD in developing countries. Aim and methods This study aimed to describe the current trend in the burden and population characteristics of CKD in Southern Nigeria. This is a cross-sectional, hospital-based study. The study recruited adult patients with prehemodialysis CKD seen in renal clinics over a two-year period (November 2014 to October 2016). Data were obtained using a questionnaire and from the clinic register. All participants were clinically assessed, including history, anthropometric measurements, and urinary albumin-creatinine ratio. Results A total of 1,549 patients were seen at the Medical Outpatient Clinic over the study period. CKD accounted for 9.7% of medical outpatient clinic attendance. The mean age of participants was 49±13 years. The leading causes of CKD were diabetes mellitus (32%), chronic glomerulonephritis (30%), and hypertension (22%). Among the participants, CKD stages 3, 4, and 5 were prevalent in 26.7%, 43.3%, and 14.7%, respectively. Conclusion and recommendation CKD is very prevalent among medical clinic patients. Diabetic nephropathy seems to be a more significant cause of CKD than was previously reported. Late presentation of patients to nephrologists remains an obstacle to improving CKD outcome in Nigeria. There is need for more intensive preventive measures and early intervention.
