Renal functional reserve (RFR) is the kidney capability of increasing its basal glomerular filtration rate (GFR) at least 20% after an adequate stimulus. Renal disorders have been reported in seropositive HIV patients, particularly the decrease in glomerular filtration rate (eGFR), nephrotic syndrome, and proximal tubular deficiency associated with the disease itself or the use of some anti-retroviral treatments. Thus, it was decided to carry out a prospective study in order to evaluate if RFR test was preserved in naive HIV patients. Material and Method. GFR was measured by using cimetidine-aided creatinine clearance (CACC), and RFR as described Hellerstein et al. in seropositive naive HIV patients and healthy volunteers. Results. RFR was evaluated in 12 naïve HIV patients who showed positive RFR (24.8±2%), but significantly lower compared to RFR in 9 control individuals (90.3 ± 5%). Conclusion. In this study was found that renal functional reserve was positive in naïve HIV patients, but significantly lower compared to renal functional reserve achieved by seronegative healthy individuals.pdfItaAttribution-NonCommercial-NoDerivs 3.0 United Statesinfo:eu-repo/semantics/openAccess10.69097/41-04-2024-11https://giornaleitalianodinefrologia.it/en/2024/08/41-04-2024-11/Artículo científicoRenal reserveHIVRenal physiology
