High levels of viral loads, low CD4 cell counts, diagnosis of acquired immunodeficiency syndrome (AIDS), low body weight, and the use of some antiretroviral agents, such as indinavir, tenofovir disoproxil fumarate (TDF), and ritonavir-boosted lopinavir (LPV/r), are well-documented risk factors for CKD in HIV-infected individuals [6,7,8,9]. Here, CD4 is linked to AIDS.
