Chronic kidney disease screening: Results of the 2013 World Kidney Day activities conducted at the Jos University Teaching Hospital

Background: Chronic kidney disease (CKD) is on the rise globally due to the increase in prevalence of common risk factors. Screening for CKD risk factors is important for early detection and institution of measures to retard its progression. This study aimed to determine the markers of CKD and its risk factors in a selected population.Methods: A cross sectional study of 510 individuals who were recruited during the 2013 world kidney day activities. History, clinical examination as well as the collection of urine and blood samples was performed on each participant to determine the presence of CKD and its risk factors. CKD markers were defined as the presence of proteinuria and or an estimated glomerular filtration rate (eGFR) of < 60ml/min.Results: The mean age of the participants was 39±11 years with majority of them being females (64.7%). Hypertension was present in 256 (50.2%) while diabetes mellitus was seen in 27 (5.29%). Forty three individuals (8.4%) had proteinuria while the prevalence of CKD markers was 10.5%. Only age, (OR =1.03; 95% CI: 1.01-1.06) was found to be a factor independently associated with the development of CKD. Conclusion: Though the prevalence of the traditional risk factors for CKD was high, only age was found to be independently associated with CKD markers.Screening exercise is encouraged for the early detection of CKD markers with a view to mitigating their impact

Association of HIV-induced immunosuppression and clinical malaria in Nigerian adults

Abstract Despite the growing body of evidence on the interaction between HIV and malaria in sub-Saharan Africa, there is a dearth of data on clinical malaria in HIV-infected patients in Nigeria. We determined the burden of clinical malaria in HIVinfected adult Nigerians and further investigated the association between their immunological status and the rates of clinical malaria. Ninety seven antiretroviral treatment-naïve HIV-infected adults were enrolled in a cross-sectional study from August to December, 2009. The participants had a complete clinical evaluation, thick and thin blood films for malaria parasites and CD4 cell count quantification. Clinical malaria was defined as having fever (temperature ≥ 37.5oC or history of fever within 48 hours) and a malaria parasite density above the median value obtained for subjects with co-existing fever and parasitaemia. Clinical malaria was diagnosed in 10 out of 97 patients (10.3%). Lower CD4 cell counts were associated with increasing rates of clinical malaria which was 0% at CD4 cell count of ≥ 500, 2.6% at 200-499 and 30% at <200 cells/µL (χ2 = 18.3, p = 0.0001). This association remained significant after controlling for other factors in a multivariate analysis (AOR=22.98, 95% C.I: 2.62-20.14, p= 0.005). An inverse relationship between CD4 cell count and parasite density was demonstrated (regression co-efficient = -0.001, p = 0.0002). More aggressive malaria control measures are highly needed in severely immunosuppressed HIV-infected patients
