Objective To investigate the changes of the T lymphocytes and their subsets before and after receiving highly active anti-retroviral therapy (HAART) in children who were infected with HIV or AIDS patients. Methods Ninety-nine children met the criteria were recruited. All of them had received HAART in Guangxi Center for Disease Control and Prevention from May 2006 to April 2009. Peripheral blood of 2 milliliter was collected before treatment (D0) and after 3,6,12,18,24,30, and 36 months ( M3, M6,M12,M18, M24, M30 and M36), respectively. Four-color fluorescence flow cytometry was used for the detection of the absolute numbers of CD3 +, CD4+, CD8 + T lymphocytes in peripheral blood. And then, the percentages of CD3 +, CD4+, CD8 + T lymphocytes in the CD45 + cells and the ratio of CD4/CD8 were calculated. Results Sixteen-five ( 65. 66% ) cases were treated with lamivudine ( 3TC )/zidovudine (AZT) /nevirapine ( NVP), and 16 ( 16. 16% ), 8 ( 8. 08% ) and 10 ( 10. 10% ) cases were treated with 3TC/stavudine ( D4T)/NVP,3TC/AZT/efavirenz (EFV) and 3TC/AZT/Ipv-rtv(LPV/r), respectively. The median of the ratio of CD4/CD8 were 0. 39,0. 51,0. 61,0. 65,0. 70,0. 73 and 0. 76 in M3,M6,M12,M18,M24, M30 and M36, respectively which were significantly higher than that in D0(0.19) ( Z values were -5. 158, -7. 375, - 9. 078, - 8. 853, - 8. 373, - 5. 845 and - 5.844 respectively, P ＜ 0.000). The median of CD4% were 16. 92% ,22.70% ,25.54% ,26. 66% ,27.99% ,30. 36% and 29. 30% respectively in M3, M6, M12, M18, M24, M30 and M36 respectively,which were also higher significantly than that in D0 (9.92%) (Zvalues were -5.268, -7.568, -9.496, -9.171, - 8.760, -6.190 and -5.964 respectively, P＜0.000 ) . In addition, the median of the absolute numbers of CD4+ T lymphocytes in peripheral blood were 631,813,1050,946, 1057,1166 and 894 cells/mm3 respectively in M3, M6, M12,M1 8, M24, M30 and M36, which were higher significantly than that of D0 (382 cells/mm3) (Z values were -3.318, -5. 288, -6. 661, -5. 886, -5. 801, -4.110 and -3. 600 respectively,P ＜0. 000). However,the median of CD8% were 47.25%, 43.01%, 43.04%, 42.60%, 41.37%, 40.83% and 38.31% respectively in M3, M6, M12, M18, M24, M30 and M36, which were lower significantly than that of D0 (53.17%) (Zvalues were -3.082, -4.697, -5.282, -5.846, -5.757, -3.883 and -4.380 respectively, P＜0.001 ). Conclusion There is certain rules for the changes of T lymphocytes and their subsets ,which may play important roles in the evaluation of the therapeutic effect and the clinical application guidance of HAART.
