Risk factors for renal disease in HIV-infected people

Risk factors associated with an increased risk of CKD are well recognised. Some of these are modifiable, emphasising the importance of their early detection and management19. Renal risk factors may be specific to patients with HIV; other ‘traditional’ renal risk factors have overlap with those seen in the HIV non-infected patient group, as shown in Table 120,21. It is important to consider an individual patient’s overall risk of renal disease at the time of diagnosis, and to modify their ART and subsequent monitoring accordingly, though even patients on non-nephrotoxic ART remain at high risk of renal disease21.
