HC: Healthy control; PTB: pulmonary Mycobacterium tuberculosis; Above 500 cells/μl: HIV-1 subjects with CD4 count above 500 cells/μl; 500>X>250 cells/μl: HIV-1 subjects with CD4 count between 500 and 250 cells/μl; Below 250 cells/μl: HIV-1 subjects with CD4 count less than 250 cells/μl.
Table 1: Demographic and immunological characteristic of individuals within studied subgroups. Data expressed as median.There was no significant difference between CD4 count from HIV-1 subjects with CD4 count >250 cells/μl and HIV-1/PTB co-infected individuals. Strangely, we found significantly low mean CD4 count in individuals with active PTB [HIV-1/2 negative] when compared to HC.
