RESUMO
<p><b>OBJECTIVE</b>To investigate the clinical significance and detection of the expression of CD25- CD127- on CD4+ T cells in peripheral blood in patients with hepatitis B.</p><p><b>METHODS</b>The expression of CD25- CD127- on CD4+ T cells were measured by using flow cytometry in 53 patients with chronic hepatitis B, 53 carrier with hepatitis B virus and 26 healthy blood donors, and follow up 20 patients with HBV-DNA positive treated with interferon.</p><p><b>RESULTS</b>(1) Compared with healthy controls, the expression of CD25- CD127- on CD4+ T cells in patients and carrier with hepatitis B virus were lower (Q = 4.559, P < 0.05; Q = 6.230, P < 0.05). (2) The expression of CD25- CD127- on CD4+ T cells in patients with HBV-DNA positive (n = 77) was lower than that of negative (n = 29) (t = 2.290, P = 0.024). (3) Compared with the prior treatment,the expression of CD25- CD127- on CD4+ T cells in patients with B hepatitis were lower after interferon treated with 12 weeks (t = 2.469, P = 0.024).</p><p><b>CONCLUSION</b>It suggested that the CD25- CD127- expression on CD4+ T cells correlated with viral infections and cleared,exogenous interferon could decrease CD25- CD127- expression on CD4+ T cells.</p>
