Project description:ObjectivesNucleos(t)ide analogues (NUCs) are not routinely recommended for patients with hepatitis B e antigen-positive chronic hepatitis B virus (HBV) infection who have persistently elevated serum HBV DNA level (>20,000 IU/mL) but normal alanine aminotransferase (<40 IU/L) level. Here, we evaluated the cumulative risks of hepatocellular carcinoma (HCC) in such patients (the untreated persistently elevated serum HBV DNA [pEDNA] group) compared with inactive carriers (the IC group).MethodsPatients with untreated pEDNA (n = 126) and IC (n = 621) were enrolled between 2006 and 2012. Patients with cirrhosis or HCC at enrollment or a history of NUC treatment were excluded.ResultsThe cumulative HCC risks at 5 and 9 years in the untreated pEDNA group were 1.1% and 1.9%, which were comparable with those of the IC group (P = 0.549). Inverse probability of treatment weighting and propensity score matching also showed similar HCC risks. In the untreated pEDNA group, there were no cases of HCC in the subgroup with serum HBV DNA level >1,000,000 IU/mL (immune-tolerant phase), which was significantly (P = 0.002) different compared with those with an intermediate serum HBV DNA level (20,000-1,000,000 IU/mL).DiscussionThe cumulative HCC risk in the untreated pEDNA group was minimal and comparable with that of the IC group. Further studies are required to determine whether early NUC treatment, indeed, reduces the HCC risk in patients with an intermediate serum HBV DNA level.

Project description:BackgroundChronic hepatitis B virus (HBV) infection remains a serious health issue, and determining the optimal time for antiviral therapy is challenging. We aimed to assess liver histological changes in patients with HBeAg-positive chronic hepatitis B (CHB) and those with HBeAg-negative CHB who had persistently normal alanine aminotransferase and to determine the association between significant liver injury and various clinical parameters.MethodsWe retrospectively included, in this study, 339 treatment-naïve patients with chronic HBV infections who had persistently normal alanine aminotransferase and underwent liver biopsy from 2013 to 2023. Histologic assessment was based on the Metavir scoring system to evaluate the association between clinical characteristics and the severity of liver inflammation and fibrosis.ResultsAmong the included participants, 138 were HBeAg-positive and 201 were HBeAg-negative. Lower hepatitis B surface antigen (HBsAg) (P = 0.003) and higher aspartate aminotransferase (AST) (P = 0.002) levels were associated with significant necroinflammation, whereas increasing age (P = 0.004) and lower HBV DNA (P < 0.001) levels were associated with significant fibrosis in HBeAg-positive patients with normal ALT levels. Higher HBV-DNA (P = 0.001) and AST levels(P < 0.001) were associated with significant necroinflammation, and higher AST(P < 0.001) levels were associated with significant fibrosis in HBeAg-negative patients.ConclusionsA substantial proportion of patients with HBV infection who had normal ALT presented significant liver injury. HBsAg and AST were independent predictive factors for evaluating inflammation, while HBV DNA load and age were independent predictive factors for evaluating fibrosis in the HBeAg-positive group. HBV DNA load and AST were independent predictive factors for evaluating inflammation, while AST were independent predictive factors for evaluating fibrosis in the HBeAg-negative group.

Project description:ObjectiveThe present study aimed to investigate the association between serial serum alanine aminotransferase (ALT) and spontaneous hepatitis B e antigen (HBeAg) seroconversion age in chronic hepatitis B virus (HBV)-infected children.Patients and methodsOne hundred four HBeAg-positive chronic genotype B or C HBV-infected patients were included in this long-term prospective cohort study (mean initial age 7.20 years). Serial serum ALT levels and HBV serology markers were measured every 6 to 12 months. The 104 subjects made a total of 2525 visits during the study period, and the majority (93.6%) of visits were within a 1-year interval apart from previous visits. Cox proportional hazards model with time-dependent covariates was used in the survival analysis of HBeAg in these subjects.ResultsDuring the chronic course of HBV infection, the median remaining times to spontaneous HBeAg seroconversion were 8.35, 5.14, 4.25, 3.95, and 2.80 years after the ALT levels crossed 20, 30, 40, 60, and 150 IU/L, respectively. The incidence rate of spontaneous HBeAg seroconversion within 6 months when a subject entered the phase of ALT between 60 and 150 IU/L was 5.57 times that of the phase with ALT < 60 IU/L. The incidence rate of HBeAg seroconversion once ALT levels were above 150 IU/L was 9.87 times that of the phase of ALT < 60 IU/L.ConclusionsThe ALT levels above 30 IU/L served as a cutoff of the inflammatory phase in chronic genotype B and C HBV-infected patients. Serial ALT levels in chronic HBV-infected subjects offer a predicted effect on the occurrence of spontaneous HBeAg seroconversion.

Project description:AbstractEarly and accurate diagnosis of liver fibrosis is necessary for HBeAg-positive chronic hepatitis B (CHB) patients with normal or slightly increased alanine aminotransferase (ALT), Liver biopsy and many non-invasive predicting markers have several application restrictions in grass-roots hospitals. We aimed to construct a non-invasive model based on routinely serum markers to predict liver fibrosis for this population.A total of 363 CHB patients with HBeAg-positive, ALT ≤2-fold the upper limit of normal and liver biopsy data were randomly divided into training (n = 266) and validation groups (n = 97). Two non-invasive models were established based on multivariable logistic regression analysis in the training group. Model 2 with a lower Akaike information criterion (AIC) was selected as a better predictive model. Receiver operating characteristic (ROC) was used to evaluate the model and was then independently validated in the validation group.The formula of Model 2 was logit (Model value) = 5.67+0.08 × Age -2.44 × log10 [the quantification of serum HBsAg (qHBsAg)] -0.60 × log10 [the quantification of serum HBeAg (qHBeAg)]+0.02 × ALT+0.03 × aspartate aminotransferase (AST). The area under the ROC curve (AUC) was 0.89 for the training group and 0.86 for the validation group. Using 2 cut-off points of -2.61 and 0.25, 59% of patients could be identified with liver fibrosis and antiviral treatment decisions were made without liver biopsies, and 149 patients were recommended to undergo liver biopsy for accurate diagnosis.In this study, the non-invasive model could predict liver fibrosis and may reduce the need for liver biopsy in HBeAg-positive CHB patients with normal or slightly increased ALT.

Project description:Noninvasive fibrosis tests are highly needed but have not been well studied in chronic hepatitis B patients with normal or minimally elevated alanine aminotransferase (ALT) levels. This study is aimed at developing a noninvasive score system to predict liver fibrosis in these patients. HBeAg-positive chronic hepatitis B patients with ALT levels of <80 IU/l and liver histology (n = 290) were assigned to training (n = 203) or validation (n = 87) groups. Training group patients were divided into nonsignificant (F0-1) and significant fibrosis (F2-4) according to METAVIR stages. Logistic regression was performed to identify factors for liver fibrosis and develop a score system. The capacity of the score to identify the severity of fibrosis was displayed by receiver operating characteristic curve (ROC) and area under ROC (AUROC) values. Multivariate logistic regression showed that HBeAg (ratios of the sample to the cutoff values (S/CO)) and liver stiffness measurement (LSM; kilopascals (kPa)) were independent factors of liver fibrosis. A score system composed of HBeAg and LSM by assigning a point of 1, 2, or 3 to different HBeAg and LSM levels, respectively, was developed. The scores 2-3, 4, and 5-6 of the sum of HBeAg and LSM points indicated nonsignificant, indeterminate, and significant fibrosis, respectively. The score system had an AUROC of 0.880 and showed similar performance in validation group patients. The accuracy for identifying significant and nonsignificant fibrosis was 77.14% in validation group patients and 71.26% in the entire group of patients. It is suggested that this noninvasive score system can accurately predict hepatic fibrosis and may reduce the need for liver biopsy in HBeAg-positive patients with normal or minimally elevated ALT levels.

Project description:Background & aimsVirological breakthrough (VBT) could be a manifestation of chronic hepatitis B (CHB) in patients treated with long-term nucleot(s)ide analogues. We aimed to determine the association of on-treatment serum hepatitis B virus (HBV) DNA with VBT in HBeAg-positive CHB patients receiving entecavir (ETV) treatment.MethodsA retrospective cohort study, including 162 consecutive patients (95 men and 67 women; mean age, 43.1±13.4 years) with HBeAg-positive CHB treated with ETV for at least 48 weeks between August 2008 and May 2015, was conducted. Univariate and multivariate cox regression analysis were used to identify associations with VBT and clinical factors, including HBV DNA and HBeAg serum status.ResultsAmong the 162 ETV-treated HBeAg-positive CHB patients, eighteen patients (11.1%) experienced VBT (VBT group), whereas the other 144 patients were without VBT (non-VBT group). The cumulative rate of HBV DNA < 100 IU/mL in the VBT group and the non-VBT group at week 48 were 44.44% and 70.14%, and at week 96 were 58.33% and 92.56%, respectively (p = 0.015). The cumulative rate of HBeAg seroclearance in the VBT group and non-VBT group at week 48 and week 96 were statistically significant (p = 0.014). Multivariate analysis disclosed that failure to achieve HBeAg seroclearance were the factors significantly associated with VBT.ConclusionsOur results demonstrated that on-treatment HBV DNA could probably predict VBT in ETV-treated HBeAg-positive chronic hepatitis B patients. Failure to achieve HBeAg seroclearance was associated with VBT in ETV-treated HBeAg-positive CHB patients. HBV DNA >100IU/mL at 48 weeks is potentially a predictor for VBT.

Project description:Alanine transaminase (ALT) abnormalities are common in chronic hepatitis B (CHB) carriers during postpartum period. Disturbances in cytokines are considered to be associated with hepatitis Flares. There are limited data on cytokines changes in HBeAg positive patients with ALT abnormalities.This is an observational study. Pregnant patients with hepatitis B e-antigen (HBeAg) positive were enrolled from January 2014 to September 2018. Patients were assigned into three groups based on ALT levels in postpartum 6 to 8 weeks: ALT in normal range, ALT in 1 to 2-fold upper limits of normal (ULN) and ALT >2-fold ULN. Serum cytokines, ratios of regulatory T cells, and the concentration of cortisol were collected and compared among the three groups.Of the 135 mothers enrolled, 80.7% (109/135) completed the postpartum 6-week study. 13.8% (15/109) patients had postpartum ALT higher than 2ULN, 27.5% (30/109) patients had ALT in 1 to 2ULN and 58.7% (64/109) patients had ALT in normal range. Compared to control group, patients with ALT >2ULN had a higher IL-10 level (P < .05). No differences of IL-10 levels were found in the comparison of other inter comparison among three groups. No differences were found in the levels of other collected serum cytokines, cortisol, and regulatory T cells among three groups. On multivariate analysis, abnormal IL-10 level was independent risk factor for postpartum ALT elevating >2ULN. At the same time, the incidence of postpartum ALT elevated >2ULN were higher in patients with abnormal elevation IL-10 level than in patients with normal IL-10 level (14/68 vs 1/41, P = .008).CHB patients with postpartum ALT abnormalities show higher IL-10 level and postpartum ALT abnormalities were mainly occurred in patients with abnormal IL-10 level. IL-10 may be an underlying predictor and treatment target of hepatitis B, and further studies are needed.

Project description:BackgroundThere are inadequate data and no histological evidence regarding the effects of antiviral treatment for hepatitis B e-antigen (HBeAg)-negative chronic hepatitis B (CHB) patients with normal or mildly elevated alanine aminotransferase (ALT). This study investigated the effects of antiviral treatment on these patients.MethodsWe retrospectively analysed the outcomes of antiviral treatment for HBeAg-negative CHB patients with normal or mildly elevated ALT who were treated with nucleoside/nucleotide analogues (NAs) for up to 96 weeks.ResultsA total of 128 patients were enrolled; 74 patients had normal ALT and 54 patients had mildly elevated ALT. The total cumulative rates of viral suppression were 64.06%, 81.97%, and 96.39%, at weeks 24, 48, and 96, respectively. The cumulative rates of viral suppression for the normal and mildly elevated ALT groups were 67.85% and 58.97%, 86.39% and 76.31%, and 93.13% and 97.04% at weeks 24, 48, and 96, respectively. The serum HBV DNA levels at week 12 and hepatitis B surface antigen (HBsAg) levels at week 24 were significant predictors of the 96-week virological response. Of the 128 patients, 54 with normal ALT and 33 with mildly elevated ALT underwent FibroScan at baseline. Significant fibrosis (F ≥ 2) was found in 44.4% (n = 24) and 51.5% (n = 17) of the patients in the normal ALT group and mildly elevated ALT group, respectively. Compared with the values at baseline, liver stiffness values significantly decreased at week 48 (8.12 kPa vs. 6.57 kPa; p < 0.001) and week 96 (8.87 kPa vs. 6.43 kPa; p < 0.001), respectively.ConclusionsHBeAg-negative CHB patients with normal ALT could benefit from antiviral therapy with NAs, similar to patients with mildly elevated ALT. Antiviral treatment is strongly recommended for HBeAg-negative CHB patients with normal ALT. Additionally, significant liver fibrosis is not rare in HBeAg-negative CHB patients with ALT less than two-times the upper limit of normal, and FibroScan should be performed regularly for these patients.

Project description:PurposeAbout 60-80 % of chronic hepatitis B virus (HBV) carriers are characterized with persistently normal alanine transaminase (ALT). Differences of cytokine expression are associated with the prognosis of HBV infection. We investigated the expression pattern of 30 cytokines associated with anti-HBV immunity in patients with normal ALT.MethodsFour patient groups (immune tolerance, inactive hepatitis B surface antigen carriers, resolved hepatitis B, and control; 10 subjects per group) were assigned. Thirty cytokines, including IFN-γ, IL-1β, IL-2, IL-4, IL-6, IL-7, IL-9, IL-10, IL-12p40, IL-12p70, IL-15, IL-17A, IL-17C, IL-21, IL-22, IL-23p19, IL-28A, IL-29, CCL5, CCL16, CCL20, CCL22, CXCL9, CXCL10, CXCL11, TNFRSF8, TNFRSF18, IL-6R, gp130, and TGF-β1, were measured using a human cytokine antibody array. Signal intensities were obtained by laser scanner. Protein-protein interactions were analyzed by STRING (Search Tool for the Retrieval of Interacting Genes/Proteins).ResultsSignificant differences of signal intensities were observed for IL-2, IL-4, IL-6, IL-7, IL-9, IL-10, IL-12p40, IL-12p70, IL-15, IL-21, IL-23p19, IL-28A, and IL-29. The lowest intensity was in controls. Among three HBV infection groups, significant differences were observed in IL-2, IL-4, IL-12p70, IL-15, IL-21, IL-23p19, and IL-29. The highest intensity was in the inactive group. All cytokines with significant differences were involved JAK-STAT signaling that up-regulate FOXP3, SOCS3 and MX1.ConclusionDifferential expression of cytokines in JAK-STAT signaling is an important factor associated with prognosis of HBV infection. The elevation of γC cytokines, IL-12p70, IL-23p19, and IL-29 may promote spontaneous HBeAg seroconversion and HBV clearance.

Project description:IntroductionWe aimed to elucidate the impact of metabolic syndrome (MS) and nonalcoholic fatty liver disease (NAFLD) on treatment-naïve patients with chronic hepatitis B (CHB) and normal alanine aminotransferase (ALT).MethodsWe analyzed the clinical characteristics of a cross-sectional cohort of treatment-naïve patients with CHB and ALT in the upper limit of normal (ULN) from October 2018 to July 2021. ALT ≤ 0.5 ULN was stratified as low-normal ALT (LNALT) and 0.5 ULN < ALT ≤ ULN as high-normal ALT (HNALT). Transient elastography (TE) was used to evaluate liver steatosis and fibrosis.ResultsAmong 733 patients with CHB enrolled, 23.1% of them had MS, 37.2% of them had NAFLD, and 5.9% of them had significant fibrosis. The proportions of patients with MS, steatosis, and significant fibrosis in the HNALT group were higher than those in the LNALT group (31.4% vs. 14.1%, p < 0.001; 48.7% vs. 25.2%, p < 0.001; and 8.0% vs. 3.6%, p = 0.013, respectively). Multiple linear regression showed that steatosis (beta = 0.098, p = 0.001) and MS (beta = 0.092, p = 0.002) were independently related to ALT levels in the normal range. Multivariate logistic regression showed that age (OR 1.049, 95% CI 1.012-1.087, p = 0.010), aspartate aminotransferase (AST) (OR 1.059, 95% CI 1.005-1.115, p = 0.030), and severe steatosis (OR 2.559, 95% CI 1.212-5.403, p = 0.014) were independently associated with significant fibrosis. When analyzed in the subgroup of CHB with NAFLD, age (OR 1.060, 95% CI 1.006-1.117, p = 0.029) and severe steatosis (OR 2.962, 95% CI 1.126-7.792, p = 0.028) were still statistically significant.ConclusionThe accumulation of MS components exacerbated hepatic steatosis. Severe NAFLD was independently associated with significant fibrosis. This emphasizes the importance of screening for MS and NAFLD in patients with CHB and normal ALT, where a more active intervention may apply.
