Highly active antiretroviral therapies (HAARTs) are used for the management of human immunodeficiency virus and acquired immunodeficiency syndrome (HIV/AIDS). The present study was designed to characterize the neurotoxicity profile of two popular HAARTs on the brains’ antioxidants and hippocampal microanatomical alterations in an in vivo model. Fifteen adults male Wistar rats, were assigned to three groups (n = 5); group I the normal control (NC) received distilled water (5 mL/kg b.wt), groups II administered with oral therapeutic doses of Efavirenz/ Lamivudine/ Tenofovir disproxil fumerate (TLE 17.14 mg/kg b.wt), and group III with Lamivudine/ Nevirapine/ Zidovudine (LNZ 9.28 mg/kg b.wt), respectively which were available for use in University of Uyo Teaching Hospital Nigeria at the time of this experiment. After a 30-day administration, biochemical parameters (catalase, superoxide dismutase, reduced glutathione, glutathione S-transferase, malondialdehyde, glutathione peroxidase, vitamins A, C and E) were determined via serum from blood of ketamine (100 mg/kg, i.p) anesthetized rats. Brains were carefully removed and post-fixed for tissue processing employing hematoxylin and eosin (H&E), cresyl fast violet (CFV) stains, and glial fibrillary acidic protein (GFAP) antibody expression. Results revealed significantly (p |
