CD4 and tuberculosis: Despite lower CD4+ T cell count at ART initiation in HIV + TB + patients (110 CD4+ cell/μl) than HIV + TB- patients (198 CD4+ cell/μl) (p = 0.001), there was no significant difference in the net increase of CD4+ T cells per month as well as in the total CD4+ cells achieved at each time point between the patients with and without TB.
