CD4 and HIV infectious disease: Hepatotoxicity was defined as an increased AST/ALT, 5-fold higher over upper, normal limits for patients with normal baseline values, or 3.5-fold if altered at baseline.<h4>Results</h4>HCV coinfection was observed in 145 patients (69%) with a longer time of HIV infection and time on HAART than mono-infected patients, and a lower nadir (182 vs 227 cells/mL; p=0.02) and baseline CD4+ count (446 vs 552 cells/mL; p=0.02).
