- Abstract: Background: Natural protection against Mycobacterium tuberculosis is based on cell-mediated immunity, which most importantly involves CD4+ and CD8+ T-cell subsets. Therefore, the evaluation of CD4+ and CD8+ T-cell profi les are important to evaluate cell-mediated immunity. Immuno-regulating therapy is important in increase of T cell subsets. Objective: To determine some T-cell subsets in active pulmonary tuberculosis patients following immunoregulating treatment in intensive phase of antituberculosis treatment, so to evaluate the treatment effect. Method: This study was conducted in TB clinic of National Center for Communicable Diseases (NCCD) between Aug 2008 and Mar 2009. CD4+ and CD8+-T cells were evaluated in 50 active pulmonary tuberculosis (infi ltrative form) cases before antituberculosis treatment (25 cases with Salimon-Study group, 25 cases without SalimonControl group) Patients with chronic disease, pregnant and alcohol users are excluded. The T cell subsets count was performed by FACSCount fl ow cytometer at the Immunology Laboratory of the NCCD,Mongolia.The monoclonal antibodies to CD3, CD4 and CD8 (Becton Dickinson) were used for the analysis. Result: CD4 count was 605,1242,7 cells/microL, CD8 count-470,92235,7 cells/microL, CD3 count-1130,7425,6 cells/microL, CD4/CD8 ratio was-1,480,67. CD4, CD8, CD3 cells were signifi cantly lower (P=0.05) in active pulmonary TB patients than in healthy Mongolian. And these subsets were signifi cantly lower in older patients (>50 age).There was no statistical signifi cance in sex and other age groups (p>0, 05). There were statistical signifi cances such as CD4 count, CD4/CD8 ratio (CD4-733,95314,38 cells/micro, CD4/CD8 ratio-1.870,7 in treatment group, CD4-570,54213.07 cells/micro, CD4/CD8 ratio-1.260.45 in control group) between TB and control group at the end of intensive phase of antituberculosis treatment (=0,05, =0,001). However, there were not any signifi cance CD8 count and CD3 count between two groups (CD8-423,68174,28 cells/microL, CD3-1212,27453,98 cells/microL in treatment group, CD8-500,67203,74cells/microL, CD3 -1139,33 386,47 cells/ microL in control group) (=0,05). Conclusion: 1. T cell subsets were signifi cantly lower in active,new,smear positive, pulmonary TB patients than in healthy Mongolians (p=0.05). 2. The statistical signifi cance is observed in 50 years and older TB patients (p=0.05). 3. CD4, CD4/CD8 were signifi cantly higher in patients treated with immuno-regulating treatment than in patients of control group (=0,05, =0,001).
