Background: At present renal dysfunction in clinical practice is measured using serum creatinine values to calculate eGFR (estimated glomerular filtration rate) but creatinine is a late marker of renal dysfunction and is only raised when up to 30-50% of renal function is lost.
Methods: Serial urine samples were analyzed by enzyme-linked immunosorbent assay for IL-18. Urinary IL-18 together with other common indicators of renal damage was assessed in 325 HIV patients; of which 66 developed renal dysfunction after 12 weeks of follow-up.
Result: Marked increase in IL-18 (p=0.000) was observed at an earlier stage in the renal disease group compared to a delayed elevation of eGFR, serum creatinine, fractional excretion of phosphate and fractional excretion of uric acid which was evident only after 4 weeks.
