  • Background: Chronic kidney disease (CKD) is now epidemic among HIV-infected populations in both Western and Eastern countries, and associated closely with a poor prognosis in them. The 2012 KDIGO guidelines elaborated on how to identify CKD patients at high risk for adverse outcomes in the general population, by combining albuminuria with estimated glomerular filtration rate (eGFR).

    Methods: Ambulatory 1947 HIV-infected patients (1829 men, 118 women, mean age: 44.9 11.5 years) who regularly visited either of the 5 tertiary hospitals in Japan were categorized, based on the new KDIGO CKD classification. Urinary albumin to creatinine ratio (ACR) was classified into 3 grades: [A1] ≤ 30mg/g, [A2] 30 - 299mg/g, and [A3] ≥ 300mg/g. 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 m2. Prevalence of CKD at likely high risk was compared with that according to the conventional CKD staging.

    Results: The prevalence of CKD ≤ stage 2 and that of CKD ≥ stage 3 classified according to the CKD staging was 90.8% and 9.2%, respectively. The prevalence of CKD categories 0+1 (low and moderately increased risks) and that of CKD categories 2+3 (high and very high risks) was 95.2% and 4.8%, respectively. This indicated that the new classification provided a reduction of nearly 50% in the proportion of high-risk CKD (Figure).

    Conclusion: The KDIGO classification may facilitate targeting of high-risk CKD in HIV-infected individuals.
