The effect of baseline egfr on 6- month and 12-month mortality with CKD-EPI, MDRD and CG formulae in patients with advanced HIV

Abstract

Background: HIV-associated renal disease was considered as an etiology of fatal condition in patients with HIV. Few equations (Chronic Kidney Disease Epidemiology Collaboration, Modification of Diet in Renal Disease and Cockcroft-Gault) have been used in clinical for calculating creatinine clearance, however the prediction of these formulae in HIV patients have been different. Our goal was to evaluate the effect of baseline eGFR by three equations on 6- month and 12-month mortality in advanced HIV patients. Materials and method: We conduct a retrospective, observation cohort study of patients with HIV infection who firstly presented for care at selected HIV OPCs in Vietnam. Results: Of total of 1108 patients was eligible for analysis. HIV- positive patients with CKD stage 3 and 4 defined by CG and MDRD formula increased risk of 6- month and 12- month mortality. CKD-EPI were not correlated with 6-month and 12-month mortality in any stage of CKD. AUC (area unde curves) for 6-month mortality and 12-month with respect to eGFR calculated by CG formula was statistically higher than AUC by CKD-EPI and MDRD (p < 0.05, Delong test). Conclusion: Low eGFR calculated by CG were associated with higher mortality in patients with advanced HIV. Key words: HIV, eGFR, CKD-EPI, MRDR, CG.
