Background There is certainly little knowledge regarding the prevalence and nature of renal impairment in African populations initiating antiretroviral treatment, nor evidence to inform the most cost effective methods of screening for renal impairment. a low prevalence of severe renal impairment (29/2189, 1.3% 481-72-1 IC50 95% C.I. 0.8C1.8) whereas moderate renal impairment was more frequent (287/2189, 13.1% 95% C.I. 11.6C14.5) with many patients having advanced immunosuppression at treatment initiation (median CD4 120 cells/l). In multivariable logistic regression age over 40 (aOR 4.65, 95% C.I. 3.54C6.1), male gender (aOR 1.89, 95% C.I. 1.39C2.56) and CD4<100 cells/ul (aOR 1.4, 95% C.I. 1.07C1.82) were Gimap5 associated with risk of significant renal impairment (ii) In 149 consecutive patients, urine analysis had poor sensitivity and specificity for detecting impaired renal function. Conclusion In this rural African setting, significant renal impairment is usually uncommon in patients initiating antiretrovirals. Urine analysis alone may be inadequate for identification of those with impaired renal function where resources for biochemistry are limited. Background Renal disease is an important complication of both HIV contamination [1] and antiretroviral treatment [2]. In a Western setting HIV-related renal disease appears to be more common in populations of African descent [3,4] and as antiretroviral roll-out continues across sub-Saharan Africa, the prevalence and nature of renal impairment in HIV positive individuals from African populations is usually of increasing importance [5]. However, little data exists around the prevalence of renal impairment before or during antiretroviral treatment in rural African areas, and in particular there is very little data from non-specialist centres or research programmes. Such information is usually important for individual patient care, the programmatic choice of antiretrovirals and strategies for monitoring toxicity. In most roll-out programmes in Sub-Saharan Africa, stavudine and lamivudine are first line medications and should have their dosages reduced in the setting of renal impairment; without doing this the opportunity of toxicity may be increased [6]. Similarly, sufferers with pre-existing renal disease will probably need nearer monitoring once treatment is set up. With a continuing discussion about the chance of presenting tenofovir as first series treatment in countries such as for example South Africa (which 481-72-1 IC50 houses around one in six from the world’s HIV positive inhabitants[7]), pursuing it’s suggestion by WHO [8], the prevalence of renal impairment assumes extra importance as sufferers with pre-existing renal impairment might either need alternative remedies or end up being at greater risk of toxicity and require more rigorous monitoring [9]. In many resource-poor settings within Sub-Saharan Africa, the diagnosis of renal impairment using blood biochemistry is not a routine matter. Point of care assessments, particularly urine analysis, offer a possible method of screening patients at risk of renal disease with the potential for targeting high risk groups for more rigorous monitoring. 481-72-1 IC50 We set out to establish the prevalence of, and risk factors for, renal impairment in a large rural South African antiretroviral programme and, in addition, to study whether the presence of renal impairment could be predicted by urine analysis. Methods Patients were recruited from a public sector support in the rural Hlabisa sub-district of KwaZulu Natal, South Africa. The neighborhood antiretroviral programme started in past due 2004 being a partnership between your Department of Health insurance and the Africa Center for Health insurance and People Research, Somkhele. The program is certainly run regarding to South African Country wide guidelines and therefore sufferers become qualified to receive treatment based on a Compact disc4 count number below 200 cells/ml or WHO Stage IV disease. To initiation with stavudine Prior, lamivudine and either nevirapine or efavirenz, sufferers have got baseline bloodstream biochemistry performed consistently, including serum 481-72-1 IC50 creatinine. Information on age group, sex, weight, Compact disc4 count number, and serum creatinine had been collected where obtainable from medical records from all 2500 individuals initiating treatment between November 2004 and June 2007. Individuals who experienced previously received combination antiretrovirals and individuals under the age of 16 years were excluded. GFR was estimated (eGFR) with the widely-used, abbreviated four variable MDRD method [2]. All individuals were of Zulu ethnicity and thus for the MDRD calculation of the prevalence of.
