AI Article Synopsis
- The study examined pulmonary function test (PFT) abnormalities in children with newly diagnosed chronic hepatitis B (CHB) over three years.
- A total of 100 children with CHB were divided into two groups (inactive carriers and immunotolerant phase), while 50 healthy children served as a control group.
- Results showed significant decreases in various lung function metrics in the CHB groups compared to their baseline and the control group, highlighting the need for ongoing PFT monitoring in affected pediatric patients.
Article Abstract
Background: The aim of this study was to evaluate the pulmonary function test (PFT) abnormalities, if any, in children with newly diagnosed chronic hepatitis B (CHB) infection over 3 years.
Methods: This is an observational case-control study. One hundred children and adolescents with newly diagnosed CHB were enrolled as the patient group that was further subdivided into 2 groups (50 patients each): inactive carriers (group I) and patients in immunotolerant phase (group II). Only 90 patients completed the study. Fifty healthy children of matched age, sex and height served as a control group, only 45 of them completed the study. PFTs in the form of forced expiratory volume in 1 s (FEV1), forced vital capacity (FVC), FEV1/FVC, residual volume, total lung capacity, mid-forced expiratory flow of 25%-75% and diffusing capacity of the lung for carbon monoxide were evaluated in all studied children at the start, yearly and at the end of the study after 3 years. Liver function tests were also evaluated.
Results: There was a significant progressive decrease in FEV1, FVC, forced expiratory flow, total lung capacity and diffusing capacity of the lung for carbon monoxide in CHB patient groups compared with their pulmonary functions at the start of the study and with the control group (P < 0.05), while FEV1/FVC and residual volume showed nonsignificant change (P > 0.05).
Conclusions: Subclinical PFT abnormalities are present in children with CHB more than we expected. So, PFT monitoring is recommended in pediatric patients with CHB.

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.

This study aims to construct and validate noninvasive diagnosis models for evaluating significant liver fibrosis in patients with chronic hepatitis B (CHB). A cohort of 259 CHB patients were selected as research subjects. Through random grouping, 182 cases were included in the training set and 77 cases in the validation set.
