Human Immunodeficiency Virus infection is a global challenge and sub-Saharan African countries contribute significantly to this pandemic. Children are vulnerable and acquire the infection mostly from their mothers. Highly Active Anti-retroviral Therapy have led to dramatic changes in the incidence of opportunistic infections with reduction in morbidity and mortality, which has paved way for manifestation of non-infectious complications including renal complications. The aim of this study was to determine prevalence of microalbuminuria, proteinuria and associated factors among Tanzanian children.
We recruited 240 HIV infected children attending care and treatment clinic. Microalbuminuria and proteinuria were determined by using dipstick and Microalbumin 2-1 combo test strips on spot urine respectively. Serum Creatinine, white blood cell and CD4 counts were determined. Renal ultrasound examinations were also performed.
Forty nine children (20.4%) had microalbuminuria and 17 (7.1%) had proteinuria. Prevalence of proteinuria was significantly higher among children aged 120 months and above (p-value<0.05). Lower CD4 percent (< 25%) was a risk factor for microalbuminuria (p-value<0.01) and proteinuria (p<0.01). Mean CD4 count was significantly lower in children with microalbuminuria (p-value<0.05) and proteinuria (p-value <0.001). Twenty eight (11.7%) children out of 153 had increased cortical echogenicity on ultrasound examination.
Proteinuria and increased cortical echogenicity were prevalent among HIV infected children who may indicate early onset of renal complications and this call for routine screening for early detection.
