Kidney disease represents an important health concern among HIV-infected individuals, with an estimated prevalence ranging between 2.4 and 17%. The widespread use of antiretroviral drugs has changed the epidemiology of kidney disease in the HIV positive population, drastically reducing the percentage of patients affected by HIV-associated nephropathy (HIVAN), a complication characterized by apoptosis and de-differentiation of renal epithelial cells and podocytes. However, impaired kidney function remains an important issue among HIV-infected patients because of their long-term exposure to antiretroviral drugs and the growing burden of traditional risk factors associated with chronic renal disease. Furthermore, since HIV infects renal epithelial cells, kidney is a potential reservoir site that needs to be considered in future eradication studies. This review summarizes the main risk factors associated with chronic kidney disease in HIV-infected patients and discusses the contribution of viral infection and antiretroviral therapy to the pathogenesis of renal damage, emphasizing the need to monitor kidney status during the follow-up of HIV-infected patients.
