The effect of hepatitis B virus on T lymphocyte and its subsets in chronic hepatitis B patients in different ALT stages: A new concept ALT in HBV infection.
2021
The aim of the present study was to explore the effect of hepatitis B virus on T lymphocyte and its subsets in different ALT states, and elucidate the immunological mechanism of ALT basing antiviral therapy for hepatitis B. 363 chronic hepatitis B patients were selected as the study subjects. According to ALT abnormalities, the patients were divided into three study groups. ALT normal group 131 cases, normal≦ ALT 0.05). In the ALT ≥ double upper limit of normal group. with the virus load increased, The total number of T lymphocytes, CD3+ CD4 + T lymphocytes decreased, (P < 0.05)CD3+ CD8 + T lymphocytes increased(P < 0.05). With the virus load increased the cytokines IL-2, IFN-γ which reflect the Th1 lymphocytes increased(P < 0.05), the cytokines IL-4、IL-10 which reflect the Th2 lymphocytes decreased(P < 0.05). Before and after 24 weeks of entecavir treatment, the patient's HBV-DNA decreased significantly(P < 0.05) and the body's immune function improved significantly. (P < 0.05)The influence of hepatitis B virus on immune function is different in different ALT states. Therefore, the scientific significance of ALT grouping in the hepatitis B treatment can be clarified from the immunological point.
