Chronic Hepatitis B in Indian Americans: Lack of Screening and Poor Linkage to Care

Background: Chronic hepatitis B (CHB) is a major cause of liver-related morbidity and mortality in the United States (US) and globally. CHB disproportionately affects Asian Americans and many other immigrant minority populations, primarily owing to the high prevalence of CHB in their countries of origin. India is a country with a medium-to-high prevalence of hepatitis B (HB) (>2%) and has over 40 million people infected with hepatitis B virus (HBV), with more than 115,000 deaths annually from HBV-related complications. Indian Americans are one of the largest immigrant populations in the US but remain underdiagnosed and poorly linked to clinical care. We, therefore, assessed the HBV prevalence and evaluated the linkage-to-care (LTC) among Indian Americans to develop strategic plans to reduce the impact of HBV in the US. Methods: Between April 2022 and January 2024, serologic screening and surveys were provided to 328 Indian American adults (age 20 - 80) in New York City. All participants were tested for a triple panel consisting of hepatitis B surface antigen (HBsAg), hepatitis B surface antibody (anti-HBs), and hepatitis B core IgG antibody (anti-HBc). A survey was conducted on the subjects chronically infected with HBV regarding their histories of infection. Self-administered questionnaires were employed to evaluate demographic and epidemiologic characteristics. Results: Of 328 screened and evaluated (246 males and 82 females), 10 (3.0%) were HBV-infected, 222 (67.7%) were susceptible to HBV, and 96 (29.3%) were immune. The prevalence of chronic HBV varied between the age groups: 4.6% (age 20 - 40), 3.4% (age 41 - 60), and 1.7% (age 61 - 80). Of 10 chronically infected, only two subjects had been previously diagnosed but were not engaged in care. Conclusion: HBV disproportionately affects Asian Americans, primarily owing to immigration from parts of the world where the disease is endemic. Indian Americans belong to an intermediate-risk group, with an HBV prevalence of >2%, but remain underdiagnosed and poorly linked to care. Our pilot study on Indian American populations, the first of its kind, demonstrates a 3% prevalence of CHB, none of whom are linked to care. In addition, this population has a high percentage of unimmune subjects, creating a large reservoir for future infection. With the growing population of Indian Americans, our findings can be used to develop community-based strategies for HBV screenings and LTC that target high-risk groups.

Factors Associated with Renal Impairment in Patients on Tenofovir for Chronic Hepatitis B in Yaoundé (Cameroon)

Background: Tenofovir (TFV) is widely used to treat patients with hepatitis B virus (HBV) infection. But kidney abnormalities are the main concern using this drug. Few studies have described the renal impairment due to the TFV in chronic hepatitis B (CHB) in Sub-Saharan Africa. The objective was to evaluate factors associated with renal impairment observed in patients on TFV for CHB. Method: It was a hospital based cross sectional prospective study carried out from June 2023 to July 2023 in Yaoundé (Cameroon) and included any patient treated with TFV for CHB during at least a period of 6 months. For each participant, we collected in the medical report socio-demographic data, clinical data, baseline creatinine, treatment information (type of TFV which was Disoproxil Fumarate (TDF) or Alafenamide (TAF), duration). Then, we collected blood samples to measure serum creatinine and phosphate levels and urine dipstick analysis. Factors associated with renal impairment were assessed with the Odds Ratio. A p value of Results: A total of 60 participants were included. The median age was 44 years [36-55] and median duration of TFV therapy was 17.5 months [11.7-25.7]. The prevalence of reduced eGFR (Conclusion: Kidney function was impaired in some patients receiving TFV for CHB. It should be monitored, particularly after 36 months and for those receiving TDF prodrug.

Lowering the threshold of alanine aminotransferase for enhanced identification of significant hepatic injury in chronic hepatitis B patients

BACKGROUND The clinical and histological features of chronic hepatitis B(CHB)patients who fall into the"grey zone(GZ)"and do not fit into conventional natural phases are unclear.AIM To explore the impact of varying the threshold of alanine aminotransferase(ALT)levels in identifying significant liver injury among GZ patients.METHODS This retrospective analysis involved a cohort of 1617 adult patients diagnosed with CHB who underwent liver biopsy.The clinical phases of CHB patients were determined based on the European Association for the Study of the Liver 2017 Clinical Practice Guidelines.GZ CHB patients were classified into four groups:GZ-A(HBeAg positive,normal ALT levels,and HBV DNA≤10^(7) IU/mL),GZ-B(HBeAg positive,elevated ALT levels,and HBV DNA<10^(4) or>10^(7) IU/mL),GZC(HBeAg negative,normal ALT levels,and HBV DNA≥2000 IU/mL),and GZ-D(HBeAg negative,elevated ALT levels,and HBV DNA≤2000 IU/mL).Significant hepatic injury(SHI)was defined as the presence of notable liver inflammation(≥G2)and/or significant fibrosis(≥S2).RESULTS The results showed that 50.22%of patients were classified as GZ,and 63.7%of GZ patients developed SHI.The study also found that lowering the ALT treatment thresholds to the American Association for the Study of Liver Diseases 2018 treatment criteria(35 U/L for men and 25 U/L for women)can more accurately identify patients with significant liver damage in the GZ phases.In total,the proportion of patients with ALT≤40 U/L who required antiviral therapy was 64.86%[(221+294)/794].When we lowered the ALT treatment threshold to the new criteria(30 U/L for men and 19 U/L for women),the same outcome was revealed,and the proportion of patients with ALT≤40 U/L who required antiviral therapy was 75.44%[(401+198)/794].Additionally,the proportion of SHI was 49.1%in patients under 30 years old and increased to 55.3%in patients over 30 years old(P=0.136).CONCLUSION These findings suggest the importance of redefining the natural phases of CHB and using new ALT treatment thresholds for better diagnosis and management of CHB patients in the GZ phases.

Evaluation of the diagnostic efficacy of noninvasive diagnosis in patients with chronic viral hepatitis B complicated with nonalcoholic fatty liver disease and significant liver fibrosis

Objective:To evaluate the diagnostic efficacy of chronic viral hepatitis B(CHB)with significant liver fibrosis(S2)in patients with nonalcoholic fatty liver disease(NAFLD)by using noninvasive diagnosis and their combined models,and to explore their clinical features.Methods:A total of 104 inpatients with CHB diagnosed and complicated with NAFLD(hepatic steatosis suggested by liver biopsy)were retrospectively collected from January 2018 to January 2023 in the Affiliated Hospital of Traditional Chinese Medicine of Xinjiang Medical University.Liver biopsy was performed in all patients.General data,laboratory test results,liver hardness(LSM),FIB-4,APRI,GGT/PLT,AST/PLT and other results of patients were collected and grouped according to different fibrosis stages(S)to explore the clinical and pathological characteristics of patients with<S2 and S2 stages.Receiver operating characteristic curve was used to evaluate the diagnostic value of LSM,FIB-4,APRI,GGT/PLT,AST/PLT and their combined models in patients with significant liver fibrosis in CHB patients with NAFLD.Results:Among the 104 patients,there were 55 patients had S1 fibrosis,32 patients had S2 fibrosis,11 patients had S3 fibrosis and 6 patients had S4 fibrosis.Patients had<S2 fibrosis,ALT 33.75±17.15 U/L,AST 24.00(19.77,29.00)U/L,inflammation above G2 stage accounted for 92.72%,GGT/PLT 0.07(0.10,0.15),AST/PLT 0.09(0.10,0.15),LSM 8.70(6.80,10.10)kPa,FIB-41.07±0.51,APRI 0.26(0.22,0.28).In patients S2 fibrosis,ALT 42.14±21.39 U/L,AST 29.04(24.00,40.32)U/L,inflammation above G2 stage accounted for 97.95%,GGT/PLT 0.15(0.10,0.28),AST/PLT 0.14(0.10,0.26),GGT/PLT 0.15(0.10,0.28),AST/PLT 0.14(0.10,0.26).LSM 11.80(8.50,16.65)kPa,FIB-41.39±0.72,APRI 0.35(0.26,0.66),the difference between the two groups was statistically significant(P<0.05).The area under the receiver operator characteristic curves of the subjects of LSM,FIB-4,APRI,GGT/PLT and AST/PLT were 0.716,0.623,0.669,0.644 and 0.669(P<0.05),respectively.In the combined model,the area under the receiver operator characteristic curves of LSM combined with FIB-4,LSM combined with APRI,LSM combined with GGT/PLT and LSM combined with AST/PLT were 0.712,0.719,0.715 and 0.719,respectively(P<0.05).Conclusion:Although the currently commonly used Noninvasive diagnosis of liver fibrosis has certain diagnostic efficacy for significant liver fibrosis in CHB complicated with NAFLD,it cannot replace liver biopsy.Noninvasive Diagnosis can be used as an auxiliary method for regular clinical evaluation of liver biopsy.

Evaluation of Non-Invasive Markers of Liver Fibrosis in Chronic Hepatitis B Patients in a Sub-Saharan African Setting: Transient Elastography versus APRI, FIB4, GTT/Platelet Scores

Background: Non-invasive markers which use routine laboratory tests are less expensive and highly needed to assess and stage liver fibrosis in chronic hepatitis B patients in Sub-Saharan Africa. We aimed at evaluating liver fibrosis, using the Aspartate aminotransferase to Platelet Ratio Index (APRI), Fibrosis Index Based on 4 factors (FIB4), and Gamma-glutamyl transpeptidase to Platelet Ratio (GPR) in chronic hepatitis B patients with transient elastography as the reference so as to choose an alternative to transient elastography. Method: We carried out a cross-sectional study using the records of patients who attended the Douala General Hospital and Marie O Polyclinic Douala from 2012 to 2017. Non-invasive tests were compared with Transient Elastography. The Spearman coefficient was used to determine correlation. The sensitivity, specificity, positive predictive values and negative predictive values were used to get the optimal cut-off values. The diagnostic accuracy was estimated by calculating the area under the Receiver Operating Characteristic Curve (ROC). P Results: Of the 243 patient records studied, the median age or interquartile range (IQR) was 35 (29 - 42) years with a male predominance of 73.7%. More than 60% of the study population had normal transaminases. Significant fibrosis was found in 88 (36.2%) patients and 32 (13.7%) patients had cirrhosis. APRI had the best cut-off values and highest area under the ROC Curve, for significant fibrosis and cirrhosis with 0.55 (0.823 95% CI [0.769 - 0.869], P Conclusion: APRI, had the best diagnostic properties to detect liver fibrosis and cirrhosis in patients with Chronic Hepatitis B in Douala. The cut-off values are 0.55 and 0.65 for significant fibrosis and cirrhosis respectively.

Value of gamma-glutamyltranspeptidase-to-platelet ratio in diagnosis of hepatic fibrosis in patients with chronic hepatitis B

AIM To investigate the value of the gamma-glutamyltraspeptidase(GGT)-to-platelet(PLT) ratio(GPR) in the diagnosis of hepatic fibrosis in patients with chronic hepatitis B(CHB). METHODS We included 390 untreated CHB patients in this study. The GPR, aspartate aminotransferase(AST)-to-PLT ratio index(APRI), and fibrosis-4(FIB-4) of all patients were analysed to determine if these parameter were correlated with age, gender, medical history, liver function [total bilirubin(TBil), alanine aminotransferase(ALT), and AST], GGT, PLT count, or hepatic fibrosis stage. The GPR, APRI, and FIB-4, as well as the combination of the GPR and APRI or the GPR and FIB-4 were assessed in different cirrhosis stages using receiver operating characteristic(ROC) curve analysis to evaluate their value in diagnosing hepatic fibrosis in CHB patients. RESULTS The GPR, APRI, and FIB-4 were not correlated withCHB patients' age, gender, or disease duration(P > 0.05), but all of these parameters were positively correlated with serum ALT, AST, GGT, and PLT count(P < 0.01). Additionally, the GPR, APRI, and FIB-4 were positively correlated with hepatic fibrosis(P < 0.01); the areas under the ROC curve for the GPR in F1, F2, F3, and F4 stages were 0.723, 0.741, 0.826, and 0.833, respectively, which were significantly higher than the respective values for the FIB-4 and APRI(F1: 0.581, 0.612; F2: 0.706, 0.711; F3: 0.73, 0.751; and F4: 0.799, 0.778). The respective diagnostic cut-off points for each stage were 0.402, 0.448, 0.548, and 0.833, respectively. The diagnostic sensitivity and specificity were, respectively, 88.8% and 87.5% in F1, 72.7% and 89.7% in F2, 81.3% and 98.6% in F3, and 80% and 97.4% in F4 when the GPR and APRI were connected in parallel; 86.6% and 90.2%, 78.4% and 96%, 78.6% and 97.4%, and 73.2% and 97.9%, respectively, when the GPR and APRI were connected in series; 80.2% and 89%, 65% and 89%, 70.3% and 98.5%, and 78.8% and 96.8%, respectively, when the GPR and FIB-4 were connected in parallel; and 83.6% and 87.9%, 76.8% and 96.6%, 72.7% and 98%, and 74.4% and 97.7%, respectively, when the GPR and FIB-4 were connected in series.CONCLUSION The GPR, as a serum diagnostic index of liver fibrosis, is more accurate, sensitive, and easy to use than the FIB-4 and APRI, and the GPR can significantly improve the sensitivity and specificity of hepatic fibrosis diagnosis in CHB when combined with the FIB-4 or APRI.

Risk of hepatitis B virus reactivation in oncological patients treated with tyrosine kinase inhibitors:A case report and literature analysis

Hepatitis B virus(HBV)reactivation(HBVr)represents a severe and potentially life-threatening condition,and preventive measures are available through blood test screening or prophylactic therapy administration.The assessment of HBVr traditionally considers factors such as HBV profile,including hepatitis B surface antigen(HBsAg)and antibody to hepatitis B core antigen,along with type of medication(chemotherapy;immunomodulants).Nevertheless,consideration of possible patient’s underlying tumor and the specific malignancy type(solid or hematologic)plays a crucial role and needs to be assessed for decision-making process.

Effect of viral hepatitis on type 2 diabetes:A Mendelian randomization study

BACKGROUND The effects of viral hepatitis(VH)on type 2 diabetes(T2D)remain controversial.AIM To analyze the causal correlation between different types of VH and T2D using Mendelian randomization(MR).METHODS Single nucleotide polymorphisms of VH,chronic hepatitis B(CHB),chronic hepatitis C(CHC)and T2D were obtained from the BioBank Japan Project,European Bioinformatics Institute,and FinnGen.Inverse variance weighted,MREgger,and weighted median were used to test exposure-outcome associations.The MR-Egger intercept analysis and Cochran’s Q test were used to assess horizontal pleiotropy and heterogeneity,respectively.Leave-one-out sensitivity analysis was used to evaluate the robustness of the MR analysis results.RESULTS The MR analysis showed no significant causal relationship between VH and T2D in Europeans[odds ratio(OR)=1.028;95%confidence interval(CI):0.995-1.062,P=0.101].There was a negative causal association between CHB and T2D among East Asians(OR=0.949;95%CI:0.931-0.968,P<0.001),while there was no significant causal association between CHC and T2D among East Asians(OR=1.018;95%CI:0.959-1.081,P=0.551).Intercept analysis and Cochran’s Q test showed no horizontal pleiotropy or heterogeneity(P>0.05).Sensitivity analysis showed that the results were robust.CONCLUSION Among East Asians,CHB is associated with a reduced T2D risk,but this association is limited by HBV load and cirrhosis.Although VH among Europeans and CHC among East Asians are not associated with the risk of T2D,focusing on blood glucose in patients with CHC is still relevant for the early detection of T2D induced by CHCmediated pathways of hepatic steatosis,liver fibrosis,and cirrhosis.

Prediction model for hepatitis B e antigen seroconversion in chronic hepatitis B with peginterferon-alfa treated based on a responseguided therapy strategy

BACKGROUND Models for predicting hepatitis B e antigen(HBeAg)seroconversion in patients with HBeAg-positive chronic hepatitis B(CHB)after nucleos(t)ide analog treatment are rare.AIM To establish a simple scoring model based on a response-guided therapy(RGT)strategy for predicting HBeAg seroconversion and hepatitis B surface antigen(HBsAg)clearance.METHODS In this study,75 previously treated patients with HBeAg-positive CHB underwent a 52-week peginterferon-alfa(PEG-IFNα)treatment and a 24-wk follow-up.Logistic regression analysis was used to assess parameters at baseline,week 12,and week 24 to predict HBeAg seroconversion at 24 wk post-treatment.The two best predictors at each time point were used to establish a prediction model for PEG-IFNαtherapy efficacy.Parameters at each time point that met the corresponding optimal cutoff thresholds were scored as 1 or 0.RESULTS The two most meaningful predictors were HBsAg≤1000 IU/mL and HBeAg≤3 S/CO at baseline,HBsAg≤600 IU/mL and HBeAg≤3 S/CO at week 12,and HBsAg≤300 IU/mL and HBeAg≤2 S/CO at week 24.With a total score of 0 vs 2 at baseline,week 12,and week 24,the response rates were 23.8%,15.2%,and 11.1%vs 81.8%,80.0%,and 82.4%,respectively,and the HBsAg clearance rates were 2.4%,3.0%,and 0.0%,vs 54.5%,40.0%,and 41.2%,respectively.CONCLUSION We successfully established a predictive model and diagnosis-treatment process using the RGT strategy to predict HBeAg and HBsAg seroconversion in patients with HBeAg-positive CHB undergoing PEG-IFNαtherapy.

Quantitative hepatitis B core antibody and quantitative hepatitis B surface antigen:Novel viral biomarkers for chronic hepatitis B management

The management of hepatitis B virus(HBV)infection now involves regular and appropriate monitoring of viral activity,disease progression,and treatment response.Traditional HBV infection biomarkers are limited in their ability to predict clinical outcomes or therapeutic effectiveness.Quantitation of HBV core antibodies(qAnti-HBc)is a novel non-invasive biomarker that may help with a variety of diagnostic issues.It was shown to correlate strongly with infection stages,hepatic inflammation and fibrosis,chronic infection exacerbations,and the presence of occult infection.Furthermore,qAnti-HBc levels were shown to be predictive of spontaneous or treatment-induced HBeAg and HBsAg seroclearance,relapse after medication termination,re-infection following liver transplantation,and viral reactivation in the presence of immunosuppression.qAnti-HBc,on the other hand,cannot be relied on as a single diagnostic test to address all problems,and its diagnostic and prognostic potential may be greatly increased when paired with qHBsAg.Commercial qAnti-HBc diagnostic kits are currently not widely available.Because many methodologies are only semi-quantitative,comparing data from various studies and defining universal cut-off values remains difficult.This review focuses on the clinical utility of qAnti-HBc and qHBsAg in chronic hepatitis B management.

Liver histological changes in untreated chronic hepatitis B patients in indeterminate phase

BACKGROUND Studies with large size samples on the liver histological changes of indeterminate phase chronic hepatitis B(CHB)patients were not previously conducted.AIM To assess the liver histological changes in the indeterminate phase CHB patients using liver biopsy.METHODS The clinical and laboratory data of 1532 untreated CHB patients were collected,and all patients had least once liver biopsy from January 2015 to December 2021.The significant differences among different phases of CHB infection were compared with t-test,and the risk factors of significant liver histological changes were analyzed by the multivariate logistic regression analysis.RESULTS Among 1532 untreated CHB patients,814(53.13%)patients were in the indeterminate phase.Significant liver histological changes(defined as biopsy score≥G2 and/or≥S2)were found in 488/814(59.95%)CHB patients in the indete-rminate phase.Significant liver histological changes were significant differences among different age,platelets(PLTs),and alanine aminotransferase(ALT)subgroup in indeterminate patient.Multivariate logistic regression analysis indicated that age≥40 years old[adjust odd risk(aOR),1.44;95%confidence interval(CI):1.06-1.97;P=0.02],PLTs≤150×10^(9)/L(aOR,2.99;95%CI:1.85-4.83;P<0.0001),and ALT≥upper limits of normal(aOR,1.48;95%CI:1.08,2.05,P=0.0163)were independent risk factors for significant liver histological changes in CHB patients in the indeterminate phase.CONCLUSION Our results suggested that significant liver histological changes were not rare among the untreated CHB patients in indeterminate phase,and additional strategies are urgently required for the management of these patients.

Chronic hepatitis B and occult infection in chemotherapy patients-evaluation in oncology and hemato-oncology settings:The CHOICE study

BACKGROUND Reactivation of hepatitis B virus(HBV)infection is a well-known risk that can occur spontaneously or following immunosuppressive therapies,including cancer chemotherapy.HBV reactivation can cause significant morbidity and even mortality,which are preventable if at-risk individuals are identified through screening and started on antiviral prophylaxis.AIM To determine the prevalence of chronic HBV(CHB)and occult HBV infection(OBI)among oncology and hematology-oncology patients undergoing chemo-therapy.METHODS In this observational study,the prevalence of CHB and OBI was assessed among patients receiving chemotherapy.Serological markers of HBV infection[hepatitis B surface antigen(HBsAg)/anti-hepatitis B core antigen(HBc)]were evaluated for all patients.HBV DNA levels were assessed in those who tested negative for HBsAg but positive for total anti-HBc.RESULTS The prevalence of CHB in the study cohort was determined to be 2.3%[95%confidence interval(95%CI):1.0-4.2].Additionally,the prevalence of OBI among the study participants was found to be 0.8%(95%CI:0.2-2.3).CONCLUSION The findings of this study highlight the importance of screening for hepatitis B infection in oncology and hematology-oncology patients undergoing chemotherapy.Identifying individuals with CHB and OBI is crucial for implementing appropriate antiviral prophylaxis to prevent the reactivation of HBV infection,which can lead to increased morbidity and mortality.

Metabolomics in chronic hepatitis C:Decoding fibrosis grading and underlying pathways

BACKGROUND Chronic Hepatitis C(CHC)affects 71 million people globally and leads to liver issues such as fibrosis,cirrhosis,cancer,and death.A better understanding and prognosis of liver involvement are vital to reduce morbidity and mortality.The accurate identification of the fibrosis stage is crucial for making treatment decisions and predicting outcomes.Tests used to grade fibrosis include histological analysis and imaging but have limitations.Blood markers such as molecular biomarkers can offer valuable insights into fibrosis.AIM To identify potential biomarkers that might stratify these lesions and add information about the molecular mechanisms involved in the disease.METHODS Plasma samples were collected from 46 patients with hepatitis C and classified into fibrosis grades F1(n=13),F2(n=12),F3(n=6),and F4(n=15).To ensure that the identified biomarkers were exclusive to liver lesions(CHC fibrosis),healthy volunteer participants(n=50)were also included.An untargeted metabolomic technique was used to analyze the plasma metabolites using mass spectrometry and database verification.Statistical analyses were performed to identify differential biomarkers among groups.RESULTS Six differential metabolites were identified in each grade of fibrosis.This six-metabolite profile was able to establish a clustering tendency in patients with the same grade of fibrosis;thus,they showed greater efficiency in discriminating grades.CONCLUSION This study suggests that some of the observed biomarkers,once validated,have the potential to be applied as prognostic biomarkers.Furthermore,it suggests that liquid biopsy analyses of plasma metabolites are a good source of molecular biomarkers capable of stratifying patients with CHC according to fibrosis grade.

Evaluation of hepatic fibrosis parameter model and elastic modulus of liver and spleen for the diagnosis of hepatic fibrosis in chronic hepatitis b

Objective Toinvestigate the diagnostic value of hepatic fibrosis parameter model and elastic modulus of liver and spleen in hepatic fibrosis of chronic hepatitis b.Methods 77 patients with hepatic fibrosis of chronic hepatitis in the infection clinic were recruited from July 2016 to December 2018.According to the classification of hepatic fibrosis,23 patients were classified as S1,20 as S2,18 as S3 and 16 as S4.The serum indexes of liver function in all patients were tested,FIB-4,APRI and GPR model indexes were calculated.SWE values of liver and spleen were evaluated,and the correlation between FIB-4,APRI,GPR and SWE was analyzed.Results The SWE values of liver and spleen in the study group were significantly higher than those in the normal group(P<0.01),and the differences in serum GGT,PLT,AST and portal vein velocity between the two groups were statistically significant(P<0.01).GGT and PLT were correlated with SWE values of liver and spleen,which were statistically significant(P<0.01).The model indexes of fib-4,APRI and GPR in the study group were all higher than those in the normal group,with statistically significant differences(P<0.01).Pearson correlation analysis showed that liver SWE value and spleen SWE value were positively correlated with fib-4,APRI and GPR,and the differences were significant(P<0.01),with a higher correlation with GPR.Conclusion GGT,PLT and GPR are positively correlated with SWE of liver and spleen,and combined detection can improve the early diagnosis accuracy of liver fibrosis.

Effect of kushenin combined with entecavir therapy on hepatic fibrosis and immune response in patients with chronic hepatitis B

Objective:To study the effect of kushenin combined with entecavir therapy on hepatic fibrosis and immune response in patients with chronic hepatitis B.Methods: Patients who were diagnosed with chronic viral hepatitis B in First Affiliated Hospital of PLA General Hospital between March 2015 and June 2017 were enrolled in the study and randomly divided into the experimental group who kushenin combined with entecavir therapy and the control group who received entecavir monotherapy. The levels of hepatic fibrosis indexes and immune cytokines in serum as well as the number of immune cells in peripheral blood were measured before treatment as well as 3 months and 6 months after treatment.Results: Compared with the corresponding indexes of same group before treatment, serum PC-III, C-IV, TGF-β1, Ang-II and IFN-γ levels as well as peripheral blood Th1 cell number of both groups of patients were significantly lower whereas Th2, mDC and pDC cell number as well as CD80 and CD86 expression intensity in peripheral blood as well as IL-5 and IL-10 levels in serum were significantly higher 3 months and 6 months after treatment;serum PC-III, C-IV, TGF-β1, Ang-II and IFN-γ levels as well as peripheral blood Th1 cell number of experimental group 3 months and 6 months after treatment were significantly lower than those of control group whereas Th2, mDC and pDC cell number as well as CD80 and CD86 expression intensity in peripheral blood as well as IL-5 and IL-10 levels in serum were significantly higher than those of control group.Conclusions: kushenin combined with entecavir treatment of chronic hepatitis B can delay hepatic fibrosis progression and improve immune response.

Effect of lifestyle modification on hepatocellular carcinoma incidence and mortality among patients with chronic hepatitis B

BACKGROUND Research exploring the influence of healthier lifestyle modification(LSM)on the risk of hepatocellular carcinoma(HCC)in patients with chronic hepatitis B(CHB)is limited.AIM To emulate a target trial to determine the effect of LSM on HCC incidence and mortality among patients with CHB by large-scale population-based observational data.METHODS Among the patients with CHB enrolled in the Korean National Health Insurance Service between January 1,2009,and December 31,2017,those aged≥20 years who drank alcohol,smoked cigarettes,and were sedentary were analyzed.Exposure included at least one LSM,including alcohol abstinence,smoking cessation,and regular exercise.The primary outcome was HCC development,and the secondary outcome was liver-related mortality.We used 2:1 propensity score matching to account for covariates.RESULTS With 48766 patients in the LSM group and 103560 in the control group,the adjusted hazard ratio(HR)for incident HCC and liver-related mortality was 0.92[95%confidence interval(CI):0.87-0.96]and 0.92(95%CI:0.86-0.99)in the LSM group,respectively,compared with the control group.Among the LSM group,the adjusted HR(95%CI)for incident HCC was 0.84(0.76-0.94),0.87(0.81-0.94),and 1.08(1.00-1.16)for alcohol abstinence,smoking cessation,and regular exercise,respectively.The adjusted HR(95%CI)for liver-related mortality was 0.92(0.80-1.06),0.81(0.72-0.91),and 1.15(1.04-1.27)for alcohol abstinence,smoking cessation,and regular exercise,respectively.CONCLUSION LSM lowered the risk of HCC and mortality in patients with CHB.Thus,active LSM,particularly alcohol abstinence and smoking cessation,should be encouraged in patients with CHB.

Tenofovir amibufenamide vs tenofovir alafenamide for treating chronic hepatitis B:A real-world study

BACKGROUND The efficacy and safety profile of tenofovir amibufenamide(TMF)in chronic hepatitis B(CHB)patients is not well-established.AIM To compare the efficacy and safety of TMF and tenofovir alafenamide(TAF)over a 48-wk period in patients with CHB.METHODS A total of 215 subjects meeting the inclusion criteria were enrolled and divided into two groups:TMF group(n=106)and the TAF group(n=109).The study included a comparison of virological response(VR):Undetectable hepatitis B virus DNA levels,alanine transaminase(ALT)normalization rates,renal function parameters,and blood lipid profiles.RESULTS At 24 and 48 wk,VR rates for the TMF group were 53.57%and 78.57%,respectively,compared with 48.31%and 78.65%for the TAF group(P>0.05).The VR rates were also similar in both groups among patients with low-level viremia,both hepatitis B e antigen(HBeAg)-positive and HBeAg-negative subgroups.The TMF cohort showed ALT normalization and renal safety profiles similar to the TAF group.There was a notable increase in total cholesterol levels in the TAF group(P=0.045),which was not observed in the TMF group(P>0.05).In patients with liver cirrhosis,both groups exhibited comparable VR and ALT normalization rates and renal safety profiles.However,the fibrosis 4 score at 48 wk showed a significant reduction in the TAF group as compared to the TMF group within the liver cirrhosis subgroup.CONCLUSION Our study found TMF is as effective as TAF in treating CHB and has a comparable safety profile.However,TAF may be associated with worsening lipid profiles.

Editorial:Metabolomics in chronic hepatitis C:Decoding fibrosis grading and underlying pathways

In the management of the growing population of hepatitis C virus-infected patients,a significant clinical challenge exists in determining the most effective methods for assessing liver impairment.The prognosis and treatment of chronic hepatitis C depend,in part,on the evaluation of histological activity,specifically cell necrosis and inflammation,and the extent of liver fibrosis.These parameters are traditionally obtained through a liver biopsy.However,liver biopsy presents both invasiveness and potential sampling errors,primarily due to inadequate biopsy size.To circumvent these issues,several non-invasive markers have been proposed as alternatives for diagnosing liver damage.Different imaging techniques and blood parameters as single markers or combined with clinical information are included.This Editorial discusses the identification of a set of six distinctive lipid metabolites in every fibrosis grade that appear to show a pronounced propensity to create clusters among patients who share the same fibrosis grade,thereby demonstrating enhanced efficacy in distinguishing between the different grades.

Relationship between the Polymorphism of the GSTP1 (rs1695) Gene and Chronic Hepatitis B Infection in Ouagadougou, Burkina Faso

Introduction: Genetic polymorphisms of some Glutathione S-Transferase (GST) which encode the enzyme responsible for the biotransformation of drugs and xenobiotics, have been associated with the risk of several pathologies that can progress to cancer such as Hepatitis B. This study aims to characterize the impact of the rs1695 polymorphism of GSTP1 gene among people with chronic Hepatitis B infection in Burkina Faso. Methods: rs1695 polymorphisms of GSTP1 gene genotyping was performed for 50 people infected with chronic Hepatitis B virus and 124 healthy people with the PCR-RFLP method. Conventional PCR was used for DNA amplification and Alw26I enzyme was used for enzymatic digestion. Results: The results show that the frequencies of AA, AG and GG genotypes are respectively 31.00%, 36.80% and 32.20% in general the study population with a mutation rate of 50.57%. However, the incidence of the AA, AG and GG genotypes are respectively 30.64%, 38.71% and 30.64% among people with chronic Hepatitis B virus infection and 32.00%, 32.00% and 36.00% among healthy people. In cases, the frequencies of the A and G alleles are 48.00% and 52.00% respectively, and in controls 50.00% each. No statistical difference was found by comparing genotypic and allelic frequencies between cases and controls (p > 0.05). Conclusion: Our study allowed us to determine the rate of GSTP1 rs1695 genotypes in the study population, cases and controls. From our analyses, GSTP1 rs1695 is not associated to chronic Hepatitis B virus infection in Ouagadougou.
