Abstract
Rationale, aims and objectives
Renal dysfunction is highly prevalent in HIV-infected patients and may require dose adjustment of renally excreted antiretroviral drugs. The Modification of Diet in Renal Disease (MDRD)-4 formula is frequently used in daily practice to estimate patients’ renal function. The aim of this systematic review was to assess the validity of the MDRD-4 formula in HIV-infected patients.
Method
A systematic search in Pubmed and EMBASE was done to identify studies which compared MDRD-4 with measured glomerular filtration rate (mGFR) in HIV-infected patients.
Results
Five studies were included, which provided data from 464 HIV-infected patients with mean mGFR ranging from 87 to 118 ml/min/1.73 m2. In all studies, results from the MDRD-4 gave an underestimation of the mGFR. Mean bias ((MDRD-4) − mGFR) ranged from −6 to −11 ml/min/1.73 m2 across studies. The accuracy expressed in terms of P
30 ranged from 64 to 89 %.
Conclusions
The MDRD-4 formula is as valid in HIV-positive as in HIV-negative patients. Because the available studies comprised mainly HIV-infected patients with mildly impaired to good renal function (GFR ≥ 60 ml/min/1.73 m2), more research is needed to validate the MDRD-4 formula in HIV-infected patients with moderate to severe renal impairment.
