Alteration in cell-mediated immunity in patients with chronic active hepatitis. I. Lymphocyte subpopulations
Insights
In patients with chronic active hepatitis B, T-lymphocyte counts were significantly lower. Monitoring T-cells is crucial for managing HBsAg-positive chronic active hepatitis.
Area of Science:
- Immunology
- Hepatology
- Virology
Background:
- Hepatitis B virus (HBV) infection can lead to chronic liver disease, including Chronic Active Hepatitis (CAH).
- The role of lymphocyte populations, particularly T-cells, in the pathogenesis and progression of chronic hepatitis B is not fully understood.
Purpose of the Study:
- To investigate the absolute numbers of T and B lymphocytes in the peripheral blood of patients with HBsAg-positive Chronic Active Hepatitis (CAH).
- To compare lymphocyte counts between patients with CAH, Chronic Persistent Hepatitis (CPH), and healthy controls.
Main Methods:
- Peripheral blood samples were collected from 25 patients with biopsy-proven HBsAg-positive CAH, 9 with HBsAg-positive CPH, and 25 HBsAg-negative healthy controls.
- Absolute counts of T and B lymphocytes were determined for all participants.
Main Results:
- Patients with CAH and cirrhosis exhibited significantly decreased total T lymphocytes compared to healthy controls.
- No significant differences in T-lymphocyte counts were observed between patients with CPH and normal controls.
- B lymphocyte counts were not detailed in the provided abstract.
Conclusions:
- The reduction in T-lymphocyte populations in HBsAg-positive CAH patients suggests an important role for T-cell immunity in this condition.
- Monitoring T-cell populations is recommended for patients with HBsAg-positive CAH to aid in disease management and understanding.
Abstract:
Absolute number of T and B lymphocytes were measured in the peripheral blood of 25 patients with biopsy proven HBsAg-positive Chronic Active Hepatitis (CAH), in 9 with Chronic Persistent Hepatitis (CPH), and in 25 HBsAg-negative healthy controls. In patients with CAH and cirrhosis total T lymphocytes were decreased; no difference were found between patients with CPH and normal controls. This data emphasize the importance of monitoring T-cells population in patients with HBsAg-positive CAH.
