AI Article Synopsis
- Immunoregulatory T cell subsets were studied in children with HBsAg-positive chronic active hepatitis, revealing a lower helper to suppressor/cytotoxic cell ratio compared to healthy controls.
- The decreased ratio was primarily due to an increase in suppressor/cytotoxic lymphocytes, especially in severe cases of chronic hepatitis.
- Treatment with azathioprine and prednisone appeared to help some patients normalize their helper/suppressor ratio, suggesting potential therapeutic effects on immune regulation in chronic hepatitis.
Article Abstract
Immunoregulatory T subsets, defined by monoclonal antibodies, were enumerated in children affected by HBsAg-positive chronic active hepatitis. The helper to suppressor/cytotoxic cells ratio was lower in patients than in age-matched controls. The lower ratio was mainly due to an increase of lymphocytes of the suppressor/cytotoxic phenotype. Helper cells were even fewer in severe chronic hepatitis patients, thereby lowering still further the helper/suppressor ratio. Therapy seemed to influence the ratio in patients affected by moderate active chronic hepatitis, for four of eight children treated with azathioprine and prednisone had a ratio within -1 SD of normal values. The increase of the suppressor/cytotoxic cells in patients affected by chronic hepatitis might be a means for limiting virus-induced cell hyperactivity.

Real-world data on treatment outcomes or the quality of large-scale chronic hepatitis B (CHB) treatment programs in sub-Saharan Africa (SSA) is extremely difficult to obtain. In this study, we aimed to provide data on the prevalence and incidence of mortality, loss to follow-up (LFTU), and their associated factors in patients with CHB in three treatment centres in Eritrea. Additional information includes baseline clinical profiles of CHB patients initiated on nucleos(t)ide analogue (NUCs) along with a comparison of treatment with Tenofovir disoproxil fumarate (TDF) vs.

It is estimated that two billion people worldwide are infected with hepatitis B. In such cases, patients exposed to the virus may experience HBV-reactivation(HBVr), which is usually due to immunosuppression. It is not anticipated that spontaneous-HBVr will occur in the absence of immunosuppression in resolved HBV.

One of the key features of chronic hepatitis B virus (HBV) infection is the inability to mount sufficient and coordinated adaptive immune responses against HBV. Recent studies on HBV-specific B cells and antibody to hepatitis B surface antigen (anti-HBs) have shed light on their role in the pathogenesis of chronic hepatitis B (CHB). Anti-HBs is recognized as a protective immune marker, both for HBV infection clearance and following vaccination, and it is also considered an important indicator of functional cure for CHB.

The natural stages of chronic hepatitis B can be divided into four stages according to changes in virology, biochemistry, and pathology. However, there have been significant differences in the recommended stage criteria in the several major guidelines for chronic hepatitis B, especially regarding the immune tolerance phase. Inconsistent standards of indicators for different stages resulted in some problems, such as incorrect stage, uncertain stages and poor comparation of related studies.
