Human Immunodeficiency Virus-associated Nephropathy

Human immunodeficiency virus-associated nephropathy (HIVAN) is characterized by high-grade protein-uria and rapid progression to end-stage renal disease (ESRD). Despite the large numbers of HIV-infected cases in Asian countries, data on HIVAN in this area are limited. We report a 54-year-old Taiwanese man with HIVAN who presented with cytomegalovirus retinitis, renal insufficiency (serum creatinine, 3.8 mg/dL) and nephrotic range proteinuria with a daily protein loss of 10.8 g. Despite highly active anti-retroviral therapy (HAART) for 31 months, renal failure developed requiring maintenance hemodialysis. Renal biopsy showed collapsing focal segmental glomerular sclerosis, podocyte proliferation and tubu-lointerstitial nephritis with mononuclear cell infiltration. These features were compatible with HIVAN. Although hemodialysis was instituted, he died 2 months later due to nosocomial pneumonia complicated with multiple organ failure. In summary, this case of HIVAN in a Taiwanese patient shows that the condition may progress to ESRD despite successful viral suppression with HAART.
