Abstract In this study, we estimated the CD4+, CD8+, CD3+ cell counts and the CD4/CD8 ratio among normal healthy controls [adults & children], Leprosy patients [without any complications and during reactional states], TB patients [with HIV & without HIV] and HIV-positive [early infection & full blown AIDS] and correlated the changes with disease progression. In our study, it was observed that among adults, CD4+ cell counts ranged from 518 to 1098, CD8+ from 312 to 952 whereas CD4/CD8 ratio from 0.75 to 2.30. Among children, both CD4+ and CD8+ cells were more and the CD4/CD8 ratio varied from 0.91 to 3.17. With regard to leprosy patients, we observed that CD4+ and CD8+ cell counts were lower among PB (pauci-bacillary) and MB (multi-bacillary) patients. CD4/CD8 ratio was 0.99 ± 0.28 among PB patients while the ratio was lower, 0.78 ± 0.20, among MB patients. CD4+ cell counts were raised during RR (reversal reactions) and ENL (erythema nodosum leprosum) among the PB and MB patients whereas the CD8+ cell counts were lower among PB and MB patients. CD4/CD8 ratio doubled during reactional episodes of RR and ENL. Among the HIV-negative TB patients, both the CD4+ and CD8+ cell counts were found to be less and the CD4/CD8 ratio varied between 0.53 to 1.75. Among the HIV-positive TB patients and HIV-positive patients, both the CD4+ and CD8+ cells were very less and ratio drops significantly. In the initial stages of infection, as CD4+ counts drop, an increase in the CD8+ cell counts was observed and the ratio declines. In the full blown cases, CD4+ cell counts were very low, 3 - 4 to 54 cells, CD8+ cells from 12 to 211 and the ratio drops too low. This study is the first of its kind in this region of the country and assumes importance since no other study has reported the values of CD4+ and CD8+ T-lymphocyte counts among patients with mycobacterial diseases (Leprosy and TB), HIV infections along with normal healthy individuals of the region and correlation with clinical presentations of patients.
