The introduction of highly active antiretroviral therapy (HAART) has reduced mortality and improved life expectancy of HIV-positive patients. However, increased survival is associated with increased prevalence of comorbidities, such as cardiovascular disease, hepatic and renal disease. Kidney disease, including HIV-associated nephropathy, acute renal failure and chronic kidney disease, represents one of the main causes of morbidity and mortality, especially if associated to other risk factors, i.e. hypertension, diabetes, older age, black race and hepatitis C coinfection. Careful evaluation of renal function may help identifying kidney disease in its early stages. In addition, proper management of hypertension and diabetes is recommended. Even if HAART has changed the natural course of HIV-associated nephropathy, reducing the risk of End-stage Renal Disease (ERDS), some antiretroviral regimens have been related with the development of acute or chronic kidney disease. Further studies are needed to optimize the management of renal disease among HIV-infected patients.
