BACKGROUND: In 2012, the Kidney Disease: Improving Global Outcomes (KDIGO) updated the 2002 Kidney Disease Outcomes Quality Initiative (KDOQI) clinical practice guideline for chronic kidney disease (CKD). The 2012 KDIGO guideline elaborated the identification and prognosis of CKD by combining albuminuria with estimated glomerular filtration rate (eGFR). Identification of CKD with a high risk for a poor prognosis was investigated in human immunodeficiency virus (HIV)-infected individuals by applying the new guideline. METHODS: A total of 1,447 HIV-infected patients (1,351 male, 96 female; mean age 44.4 ± 11.5 years) were classified using a combination of eGFR and dipstick proteinuria, as a convenient alternative to albuminuria. Proteinuria was classified into 3 grades-(A1) - and +/- , (A2) 1+ and 2+ , and (A3) 3+ and 4+. eGFR was classified into 6 grades-(G1) ≤90, (G2) 60-89, (G3a) 45-59, (G3b) 30-44, (G4) 15-29, and (G5) <15 mL/min/1.73 m(2). RESULTS: Mean CD4 cell count was 487 ± 214 /μL, with 80.7 % of patients having an undetectable HIV-RNA level. The prevalence of CKD stage ≤2 and stage ≥3 classified according to KDOQI staging was 93.4 and 6.6 %, respectively. Using the new KDIGO classification, the prevalence of CKD with either a low (green) or moderately increased (yellow) risk was 96.9 %, while the prevalence for a high (orange) and very high (red) risk was 3.1 %. CONCLUSION: The use of the new KDIGO classification may reduce the prevalence of HIV-infected CKD individuals who are at high risk for a poor prognosis by nearly a half.
