Risk factors for relapse after discontinuation of tenofovir or entecavir in hepatitis B e antigen-negative patients.

This study aimed to define the relapse frequency and risk determinants in chronic hepatitis B (CHB) patients who discontinued nucleoside analog (NA) treatment, were HBeAg-negative, and had achieved bo... This retrospective cohort study reviewed patients with HBeAg-negative CHB who received antiviral therapy for at least 65 months between January 1, 2013, and December 31, 2020. These patients discontin... Sixty-seven patients with CHB who received NA therapy for at least 65 months, discontinued treatment, and had undetectable HBV DNA and normal ALT values were evaluated. After cessation of NA therapy, ... Among HBeAg-negative CHB patients who achieved a virological and biochemical response to long-term antiviral therapy, those aged 42 years and older, those with high fibrosis scores before treatment, a...

Impact and cost-effectiveness of hepatitis B virus prophylaxis in pregnancy: a dynamic simulation modelling study.

In 2020, WHO recommended the addition of peripartum antiviral prophylaxis (PAP) to hepatitis B birth dose vaccination (HepB-BD) and hepatitis B infant vaccination (HepB3) to reduce mother-to-child tra... This modelling study used a dynamic simulation model of the HBV epidemic in 110 countries in all WHO regions, structured by age, sex, and country. We assessed three strategies of scaling up PAP for pr... Adding PAP-VL to HepB-BD could avert around 1·1 million (95% uncertainty interval 1·0 million-1·2 million) new neonatal infections by 2030 and around 3·2 million (95% uncertainty interval 3·0 million-... PAP can provide substantial health benefits, and, although the current approach might already be cost-effective in some high-burden settings, decreased diagnostic costs would probably be needed for PA... UK Medical Research Council, UK National Institute for Health and Care Research, and the Vaccine Impact Modelling Consortium....

Chronic hepatitis B: a scoping review on the guidelines for stopping nucleos(t)ide analogue therapy.

Nucleos(t)ide analogues (NAs) are effective in suppressing the replication of the hepatitis B virus. However, NAs cannot effectively induce hepatitis B surface antigen (HBsAg) seroclearance, which rep... This article covered the latest evidence on stopping NAs in CHB, with a focused analysis on international guidelines. Articles were retrieved by a literature search on PubMed with the keywords 'chroni... Finite NA therapy in CHB has the potential in enhancing HBsAg seroclearance, however it also carries rare but potentially severe risks. NA cessation before HBsAg seroclearance is only suitable for a h...

Association Between the Presence of Metabolic Comorbidities and Liver-Related Events in Patients With Chronic Hepatitis B.

Patients with chronic hepatitis B (CHB) are at increased risk of hepatocellular carcinoma and (liver-related) mortality. In addition to hepatitis B-related factors, metabolic comorbidities may contrib... We conducted a retrospective cohort study of CHB patients attending the Erasmus MC University Medical Center (Rotterdam, The Netherlands) and CHB patients who underwent liver biopsy at the Toronto Gen... We analyzed 1850 patients, of whom 926 (50.1%) were overweight, 161 (8.7%) had hypertension, 116 (6.3%) had dyslipidemia, and 82 (4.4%) had diabetes. During a median follow-up period of 7.3 years (int... Metabolic comorbidities in CHB patients are associated with an increased risk for liver-related events, with the highest risk observed in patients with multiple comorbidities. Findings were consistent...

Significant liver histological change is common in HBeAg-positive chronic hepatitis B with normal ALT.

Numerous HBeAg-positive chronic hepatitis B (CHB) patients with persistently normal ALT have significant liver histopathology. It is imperative to identify true "immune tolerant" patients. We aimed to... 179 HBeAg-positive CHB patients with normal ALT who performed liver biopsy from 2009 to 2018 were retrospectively analyzed. Liver necroinflammation ≥ G2 and/or liver fibrosis ≥ S2 was defined as signi... 57.5% patients were in the indeterminate phase with significant liver histological changes. The proportion of the patients with evident liver necroinflammation was higher in the high-normal ALT group ... HBeAg-positive CHB patients with high-normal ALT or HBV DNA < 10...

Incidence and predictors of elevated postpartum alanine aminotransferase in chronic hepatitis B mothers: a prospective study protocol.

The majority of HBeAg-positive mothers with chronic hepatitis B have high levels of viremia and inactive disease with normal alanine aminotransferase (ALT) during pregnancy. In addition, postpartum di... This study is a single-center and prospective cohort study (n = 360) that consists of two groups of patients including HBsAg-positive mothers (n = 120) and healthy mothers without HBV infection (n = 2... The current study focuses on the incidence of postpartum ALT flares in mothers with chronic hepatitis B including subgroup analysis based on HBeAg status. The data will have several clinical implicati... ChiCTR2200061130....

Effect of prophylactic antiviral intervention on T cell immunity in hepatitis B virus-infected pregnant women.

Antiviral intervention in hepatitis B virus (HBV)-infected pregnant women can effectively reduce mother-to-child transmission. However, the immunological characteristics of pregnant women with chronic... Pregnant women positive for hepatitis B surface antigen and hepatitis B e-antigen (HBsAg... At delivery, maternal regulatory T cell (Treg) frequency in AVI mothers was significantly higher than that in NAVI mothers (P < 0.002), and CD4... Prophylactic antiviral intervention during pregnancy has an effect on T cell immunity in pregnant women, which was characterised by increased maternal Treg frequency, enhanced Th2 response and suppres...

Antiviral therapy substantially reduces HCC risk in patients with chronic hepatitis B infection in the indeterminate phase.

HCC risk in chronic hepatitis B (CHB) is higher in the indeterminate phase compared with the inactive phase. However, it is unclear if antiviral therapy reduces HCC risk in this population. We aimed t... We analyzed 855 adult (59% male), treatment-naïve patients with CHB infection without advanced fibrosis in the indeterminate phase at 14 centers (USA, Europe, and Asia). Inverse probability of treatme... Antiviral therapy reduces HCC risk by 70% among patients with indeterminate-phase CHB. These data have important implications for the potential expansion of CHB treatment criteria....
