CD4 and AIDS: Twenty HIV/HCV-coinfected patients (55.0%) had AIDS according to the CDC definition (Table 1, Supplementary Figure S1).[38] When comparing baseline characteristics between patients with and without AIDS, no significant differences were found except for a significantly lower CD4+ nadir (median 77.5 [27.0–178.0] vs. 296.0 [213.0–734.0] cells/μL; P < 0.001) and a significantly lower current CD4+ count (median 315.0 [75.0–804.0] vs. 704.5 [231.0–985.0]; P < 0.01) in AIDS patients.
