Abstract
Purpose: To investigate dynamic changes and significance of lymphocyte subsets (T lymphocytes, B lymphocytes, NK cells and T cell subsets) of peripheral blood in patients with acute self-limited hepatitis B (AHB). Methods: Immune cells of peripheral blood were compared among 17 cases of self-limited acute hepatitis B patients, 36 patients with chronic hepatitis B (CHB) and 32 healthy controls by flow cytometry (FCM). CD4+/CD8+ was monitored dynamically, meanwhile relations between T lymphocyte subsets and ALT and clearance of HBV DNA were explored. Results: Dynamic changes of lymphocyte subsets were found in AHB, the level of CD3+T cells was significantly higher compared to CHB group and healthy control group. Frequencies of CD3+CD4+ T cells in the third and fourth week and CD4+/CD8+ in the second week were higher compared to other groups. Frequ- ency of NK cells was low and was significantly lower compared to other groups in the third week specially. It was showed that CD4+/CD8+ was low followed by high abnormal ALT during early stage by dynamic monitoring of CD4+/CD8+, and CD4+/CD8+ was increasing accompanied by normal ALT set by set, but CD4+/CD8+ had no significant relation to ALT and HBV DNA. Conclusion: Immune status of AHB, compared to CHB and healthy controls, was significantly different and dynamic changes of lymphocyte sub- sets may be related to progress of disease.
