Abstract
AIM: To investigate the diagnostic and therapeutic significance of CD4+CD25+CD127low/- regulatory T (Treg) cell ratio in peripheral blood of patients with chronic hepatitis C.
METHODS: Ninety-six chronic hepatitis C patients undergoing polyethylene glycol interferon (PEG-IFN) and ribavirin (RBV) therapy at Yucheng People's Hospital were assigned to an observation group, and 65 healthy volunteers were included in a control group. CD4+CD25+CD127low/-Treg ratio was detected at baseline and 24 wk after treatment. The changes of CD4+CD25+CD127low/- Treg ratio with different viral levels and liver injury were analyzed. According to whether the patients achieved a virologic response in 24 wk after withdrawal, they were divided into a sustained virologic response (SVR) group or a non-SVR group. The differences between the two groups in CD4+CD25+CD127low/-Treg ratios were analyzed at baseline and 24 wk after treatment.
RESULTS: The proportion of CD4+CD25+CD127low/- Treg cells at baseline in the observation group was significantly higher than that at baseline in the control group and that at the end of treatment in the observation group (P < 0.05). CD4+CD25+CD127low/- Treg cell ratios of patients with different load of HCV RNA were different. With the increase in HCV RNA load, CD4+CD25+CD127low/- Treg cell proportion continued to rise significantly (P < 0.05). At 24 wk after withdrawal, the rate of SVR in the observation group was 78.3%. The proportion of CD4+CD25+CD127low/- Treg cells in SVR patients was significantly lower than that of patients without SVR (P < 0.05) no matter whether at baseline or at 24 wk after treatment. Correlation analysis showed that the baseline CD4+CD25+CD127low/- Treg cell proportion was positively correlated with the liver function index AST/ALT (P < 0.05).
CONCLUSION: CD4+CD25+CD127low/- Treg cells may be involved in the pathogenesis of chronic hepatitis, and clinical detection of CD4+CD25+CD127low/- Treg cell ratio may be helpful for disease diagnosis and prognosis evaluation.
