In addition malnutrition in these children further reduces the utility of diagnostic methods such as creatinine-based estimates of glomerular filtration rate. We determined the serum cystatin C level and estimated glomerular filtration rate of 60 antiretroviral-naive HIV-infected children and 60 apparently healthy age and sex matched children. Methods Serum cystatin C level was measured using enzyme-linked immunosorbent assay technique while glomerular filtration rate was estimated using Filler s serum cystatin C formula. Student t test Mann Whitney U test Pearson chi square and Fisher s exact test were used where appropriate to test difference between groups. Results Compared to the controls the HIV-infected group had significantly higher median interquartile range serum cystatin C levels mg l versus mg l p and a higher proportion of children with serum cystatin C level 1 mg l 10 versus one p . The HIV-infected children had a mean SD eGFR of ml min m2 compared with ml min m2 in the controls p . After controlling for age sex and body mass index only the study group HIV infected versus control remained a significant predictor of serum cystatin C level b p . The proportion of HIV-infected children with eGFR 60 ml min m2 was eight versus none 0 in the control group p . However the serum cystatin C level eGFR and .
