Prevalence of renal disease in Nigerian children infected with the human immunodeficiency virus and on highly active anti-retroviral therapy

الملخص EN

Access to highly active anti-retroviral therapy (HAART) has improved the prognosis of Nigerian children infected with the human immunodeficiency virus (HIV); thus, more children are surviving.

Long-term exposure to HAART is potentially nephrotoxic.

We therefore aimed at assessing the prevalence of renal disease in Nigerian children infected with HIV, who are on HAART.

In this cross-sectional study, we studied children, aged ten months to 17 years, infected with HIV, attending the pediatric HIV clinics of the University of Benin Teaching Hospital.

Demographic and clinical data were obtained by parental interview as well as from the medical records.

Each child's urine was tested for albumin and microalbuminuria using multi test strips and mitral test strips, respectively.

The serum creatinine level of each child was also estimated and used in calculating the glomerular filtration rate (GFR).

Renal disease was defined as the presence of significant proteinuria of 1+ and above on dipstick or the presence of microalbuminuria of ≥ 20 mg and / or GFR < 60 mL / min / 1.73 m 2 .

Of the 99 children recruited, 60 were males and 39 were females.

The mean age of the children was 6.6 ± 3.5 years.

All the children were on HAART and 85 % had acquired the HIV infection by vertical transmission.

The overall prevalence of renal disease was 16.2 %.

Microalbuminuria was seen in 11 children with renal disease (11.1 %) ; 3 of them had significant proteinuria.

GFR of less than 60 mL / min / 1.73 m 2 was seen in five children (5.1 %) with renal disease, but none had end-stage renal disease (GFR less than 15 mL / min / 1.73 m 2 ).

Renal disease was found to be significantly associated with advanced stage of HIV infection (P < 0.049).

Our study showed that t he prevalence of renal disease in HAART-treated Nigerian children is high and majority of them are asymptomatic of renal disease, but in the advanced stages of HIV infection.
