Chronic viral hepatitis B (HBV) remains a major public health problem in Burkina Faso. Since access to diagnostic tests and treatments is limited because of their high cost, the majority of the population turn to traditional herbal treatments. This study aimed to evaluate the effectiveness of a plant recipe called Hepatib tiben. It consisted of comparing certain biochemical and molecular parameters of patients infected with HBV that were supported by the recipe. The patients were recruited in Ouagadougou by the traditional health practitioner according to the requirements of the study. Thus 44 patients aged 20 to 61 years and carrier of HBsAg for at least 06 months were treated with Hepatib tiben. The tests were performed in the laboratory before and three months after the treatment. ELISA tests were used to confirm the presence of HBsAg and search for anti-HCV antibodies;transaminases, creatinine were quantified by the “Chem 400” automaton and the viral load of HBV by Real-time PCR. The analysis of the results reveals an improvement of the biochemical and molecular parameters of the patients with the following means (ASAT: 21.02 ± 9.97;ALAT: 21.11 ± 13.27;DNA: 1571.82 ± 3990.97 with p = 0.01 for each). As for HBsAg, its disappearance was observed in 4.55% of patients after treatment. The evaluation of the creatinine parameter explained that the recipe of plants has a tolerated effect on the kidneys of treated patients. These results, while encouraging, need to be complemented by further research for the development of effective phytomedicine to treat and eliminate this viral hepatitis B virus. 展开更多

BACKGROUND Chronic hepatitis C(CHC)is a health burden with consequent morbidity and mortality.Liver biopsy is the gold standard for evaluating fibrosis and assessing disease severity and prognostic purposes post-treatment.Noninvasive altern-atives for liver biopsy such as transient elastography(TE)and diffusion-weighted magnetic resonance imaging(DW-MRI)are critical needs.AIM To evaluate TE and DW-MRI as noninvasive tools for predicting liver fibrosis in children with CHC.METHODS This prospective cross-sectional study initially recruited 100 children with CHC virus infection.Sixty-four children completed the full set of investigations including liver stiffness measurement(LSM)using TE and measurement of apparent diffusion coefficient(ADC)of the liver and spleen using DW-MRI.Liver biopsies were evaluated for fibrosis using Ishak scoring system.LSM and liver and spleen ADC were compared in different fibrosis stages and correlation analysis was performed with histopathological findings and other laboratory parameters.RESULTS Most patients had moderate fibrosis(73.5%)while 26.5%had mild fibrosis.None had severe fibrosis or cirrhosis.The majority(68.8%)had mild activity,while only 7.8%had moderate activity.Ishak scores had a significant direct correlation with LSM(P=0.008)and were negatively correlated with both liver and spleen ADC but with no statistical significance(P=0.086 and P=0.145,respectively).Similarly,histopatho-logical activity correlated significantly with LSM(P=0.002)but not with liver or spleen ADC(P=0.84 and 0.98 respectively).LSM and liver ADC were able to significantly discriminate F3 from lower fibrosis stages(area under the curve=0.700 and 0.747,respectively)with a better performance of liver ADC.CONCLUSION TE and liver ADC were helpful in predicting significant fibrosis in children with chronic hepatitis C virus infection with a better performance of liver ADC. 展开更多

Context/Objectives: With the progression of the global epidemic of obesity and metabolic syndrome, the coexistence of hepatic steatosis in patients with chronic viral hepatitis B (VHB) is becoming significant. The aim of this work was to determine the factors associated with hepatic steatosis assessed by a Fibroscan with Controlled Attenuation Parameter (CAP) in patients with chronic viral hepatitis B in Côte d’Ivoire. Methods: This was a cross-sectional and analytical study. Data was collected from February 15 to July 31, 2020 in a private hospital structure in the city of Abidjan in Côte d’Ivoire. We included 83 patients with chronic viral hepatitis B. These were black patients, having performed a Fibroscan/CAP during the recruitment period and consenting to participate in the study. Patients with significant alcohol consumption, a secondary cause of hepatic steatosis, or other liver disease regardless of the etiology associated with hepatitis B were not included. Results: The frequency of hepatic steatosis in chronic VHB carriers assessed by the CAP in our study population was 48.19% including 24.10% severe steatosis. Obesity and high LDL cholesterol were statistically correlated with the presence of steatosis in our patients. Patients who had steatosis on ultrasound were 5 times more likely to have steatosis on CAP. Significant fibrosis was not significantly associated with steatosis. Conclusion: Obesity and LDL hypercholesterolemia are the main factors associated with hepatic steatosis detected by Fibroscan/CAP in patients with chronic viral hepatitis B. 展开更多

Background:G-protein coupled receptors(GPCRs)are recognized as attractive targets for drug therapy.However,it remains poorly understood how GPCRs,except for a few chemokine receptors,regulate the progression of liver fibrosis.Here,we aimed to reveal the role of GPR65,a proton-sensing receptor,in liver fibrosis and to elucidate the underlying mechanism.Methods:The expression level of GPR65 was evaluated in both human and mouse fibrotic livers.Furthermore,Gpr65-deficient mice were treated with either bile duct ligation(BDL)for 21 d or carbon tetrachloride(CCl4)for 8 weeks to investigate the role of GPR65 in liver fibrosis.A combination of experimental approaches,including Western blotting,quantitative real-time reverse transcription-polymerase chain reaction(qRT-PCR),and enzyme-linked immunosorbent assay(ELISA),confocal microscopy and rescue studies,were used to explore the underlying mechanisms of GPR65’s action in liver fibrosis.Additionally,the therapeutic potential of GPR65 inhibitor in the development of liver fibrosis was investigated.Results:We found that hepatic macrophage(HM)-enriched GPR65 was upregulated in both human and mouse fibrotic livers.Moreover,knockout of Gpr65 significantly alleviated BDL-and CCl4-induced liver inflammation,injury and fibrosis in vivo,and mouse bone marrow transplantation(BMT)experiments further demonstrated that the protective effect of Gpr65knockout is primarily mediated by bone marrow-derived macrophages(BMMs).Additionally,in vitro data demonstrated that Gpr65 silencing and GPR65 antagonist inhibited,while GPR65 overexpression and application of GPR65 endogenous and exogenous agonists enhanced the expression and release of tumor necrosis factor-α(TNF-α),interleukin-6(IL-6)and transforming growth factor-β(TGF-β),all of which subsequently promoted the activation of hepatic stellate cells(HSCs)and the damage of hepatocytes(HCs).Mechanistically,GPR65 overexpression,the acidic pH and GPR65 exogenous agonist induced up-regulation of TNF-αand IL-6 via the Gαq-Ca^(2+)-JNK/NF-κB pathways,while promoted the expression of TGF-βthrough the Gαq-Ca^(2+)-MLK3-MKK7-JNK pathway.Notably,pharmacological GPR65 inhibition retarded the development of inflammation,HCs injury and fibrosis invivo.Conclusions:GPR65 is a major regulator that modulates the progression of liver fibrosis.Thus,targeting GPR65 could be an effective therapeutic strategy for the prevention of liver fibrosis. 展开更多

A patient co-infected with COVID-19 and viral hepatitis B can be atmore risk of severe complications than the one infected with a single infection.This study develops a comprehensive stochastic model to assess the epidemiological impact of vaccine booster doses on the co-dynamics of viral hepatitis B and COVID-19.The model is fitted to real COVID-19 data from Pakistan.The proposed model incorporates logistic growth and saturated incidence functions.Rigorous analyses using the tools of stochastic calculus,are performed to study appropriate conditions for the existence of unique global solutions,stationary distribution in the sense of ergodicity and disease extinction.The stochastic threshold estimated from the data fitting is given by:R_(0)^(S)=3.0651.Numerical assessments are implemented to illustrate the impact of double-dose vaccination and saturated incidence functions on the dynamics of both diseases.The effects of stochastic white noise intensities are also highlighted. 展开更多

Despite achieving a high cure rate with the direct-acting antivirals(DAAs)in hepatitis C treatment,further research is needed to identify additional benefits of the DAA therapy.The current study evaluated liver fibrosis improvement in 848 hepatitis C patients treated with DAAs,who also achieved sustained virologic response.By the fibrosis-4(FIB-4)index,patients were categorized based on their baseline fibrosis levels,and the improvement in fibrosis was analyzed in both short-term(9-26 weeks)and long-term(≥36 weeks)follow-up.The results showed a significant decrease in the FIB-4 index,indicating an improvement in liver fibrosis,in 63.0%and 67.6%of the patients during the short-term and long-term follow-up,respectively.Short-term improvement was associated with factors including ribavirin usage,blood cholinesterase levels,alanine transaminase levels,albumin levels,and the baseline FIB-4 index,while long-term improvement was associated with factors such as aspartate transaminase levels,total protein level,and the baseline FIB-4 index.The current study emphasizes the importance of continuous assessment and post-treatment monitoring of liver fibrosis,which will provide crucial insights for enhancing patient care in hepatitis C management. 展开更多

Introduction: Viral hepatitis B is a public health problem in Niger which is classified as a high endemicity area with a prevalence ranging from 8 to 17% depending on the studies [1] and that of HBV-related cirrhosis ... Introduction: Viral hepatitis B is a public health problem in Niger which is classified as a high endemicity area with a prevalence ranging from 8 to 17% depending on the studies [1] and that of HBV-related cirrhosis is about 40.26% in 2024. The decision to treat is based on a combination of three parameters: viral load, ALT values and the degree of hepatic fibrosis [2]. The latter is assessed by hepatic elastography (Fibroscan), which is a decisive factor in treatment. In Niger, until 2024, the decision to treat or not to treat a patient with HBV was based on the determination of viral load B and transaminases, and no work evaluating the contribution of this third element, liver elasticity, has been done, hence the interest of our study. Objective: To study the contribution of Fibroscan in measuring hepatic elasticity in the management of patients with HBV. Methodology: This was a prospective descriptive study conducted from January 05 to November 30, i.e. a period of 11 months, on clinically asymptomatic HBsAg-positive patients who had undergone FibroScan liver elasticity measurement. The examination was carried out by a hepatogastroenterologist who had received training in the Fibroscan. The median of ten measures of liver elasticity at the same point with an IQR of less than 30% was considered the valid measure and no or minimal fibrosis was defined as a value ˂7 Kpa, moderate fibrosis as a value between 7 and 10 kpa, severe fibrosis as a value greater than 10 Kpa, and the existence of cirrhosis as a value greater than 14 Kpa were analyzed using SPSS version 20 software. Results: Out of 398 patients monitored for HBV, 60 cases met the inclusion criteria, i.e., a frequency of 15.07%. The mean age of the patients was 35.63 years, with extremes of 18 and 70 years. They were predominantly male, with a sex ratio of 3.2. Married patients accounted for 61.67% (n = 37). Jaundice was absent in 91.67% (n = 55). The circumstances of discovery of HBV were the routine health check-up, followed by blood donation with 50% and 46.67%, respectively. The viral load was >2000 UI/ml in 32.7% (n = 17). HBeAg was negative in 93.33% of cases (n = 56). ALT levels were normal in 47 patients (78.33%). Mean liver elasticity was 6.7 KPa. Fibrosis was classified as F0 - F1 in 75% (n = 45), F1 - F2 in 18.33% (n = 11) and F3 - F4 in 6.67% (n = 4) of patients. There was no significant relationship between viremia value, liver activity, degree of fibrosis and quantitative HBsAg. Conclusion: Measurement of hepatic elasticity has made it possible to diagnose cases of compensated cirrhosis and significant fibrosis in patients considered to be inactive carriers (viral load ˂2000 IU/ml and normal transaminases) in asymptomatic HBV+ patients. This made it possible to put these patients on Tenofovir in order to avoid decompensation for the first group and for the second the progression to cirrhosis. It is an excellent tool to aid in the decision to start treatment. 展开更多

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. 展开更多

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. 展开更多

Hepatitis B remains a significant global health challenge,contributing to substantial morbidity and mortality.Approximately 254 million people world-wide live with Chronic hepatitis B(CHB),with the majority of cases occurring in sub-Saharan Africa and the Western Pacific regions.Alarmingly,only about 13.4%of the individuals infected with this disease have been diagnosed,and awareness of hepatitis B virus(HBV)infection status is as low as 1%in sub-Saharan Africa.In 2022,CHB led to 1.1 million deaths globally.The World Health Organization(WHO)has set a target of eliminating hepatitis B as a public health concern by 2030;however,this goal appears increasingly unattainable due to multiple challenges.These challenges include low vaccination coverage;a large number of undiagnosed cases;a low proportion of patients eligible for treatment under current guidelines;limited access to healthcare;and the costs associated with lifelong treatment.Treatment of HBV can yield significant clinical benefits within a long window of opportunity.However,the benefits of therapy are markedly diminished when the disease is detected at the advanced cirrhosis stage.This editorial aim to highlight the current challenges in hepatitis care and the necessary steps to achieve the WHO's hepatitis elimination goals for 2030. 展开更多

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. 展开更多

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. 展开更多

Chronic hepatitis B causes a liver disease characterized by inflammation of the liver parenchyma. The aim of this study was to investigate the evolution of biological parameters in patients treated with Tenofovir for chronic B infection at the Commune V referral health center in Bamako. We obtained a prevalence of 14.15%. The most represented age group was 31 - 40 years, with 36.8%. The sex ratio was 1.44 in favour of men. Viral load was undetectable after 18 months of treatment in 25 patients (42.37%). Tenofovir, the 1st-line drug in Mali, is effective on the biological parameters monitored in patients. 展开更多

BACKGROUND Liver condition is a crucial prognostic factor for patients with hepatocellular carcinoma(HCC),but a convenient and comprehensive method to assess liver condition is lacking.Liver stiffness(LS)measured by two-dimensional shear wave elastography may help in assessing liver fibrosis and liver condition.Chronic hepatitis B(CHB)is an important risk factor for HCC progression,but LS was found to be less reliable in assessing liver fibrosis following hepatitis viral eradication.We hypothesize that the status of hepatitis virus infection would affect the accuracy of LS in assessing the liver condition.AIM To test the feasibility and impact factors of using LS to assess liver condition in patients with HCC and CHB.METHODS A total of 284 patients were retrospectively recruited and classified into two groups on the basis of serum CHB virus hepatitis B virus(HBV)-DNA levels[HBV-DNA≥100.00 IU/mL as Pos group(n=200)and<100.00 IU/mL as Neg group(n=84)].Correlation analyses and receiver operating characteristic analyses were conducted to evaluate the relationship between LS and liver condition.RESULTS A significant correlation was found between LS and most of the parameters considered to have the ability to evaluate liver condition(P<0.05).When alanine aminotransferase(ALT)concentrations were normal(≤40 U/L),LS was correlated with liver condition indices(P<0.05),but the optimal cutoff of LS to identify a Child-Pugh score of 5 was higher in the Neg group(9.30 kPa)than the Pos group(7.40 kPa).When ALT levels were elevated(>40 U/L),the correlations between LS and liver condition indices were not significant(P>0.05).CONCLUSION LS was significantly correlated with most liver condition indices in patients with CHB and HCC.However,these correlations varied according to differences in HBV-DNA and transaminase concentrations. 展开更多

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. 展开更多

The aim of this study was to assess vaccination coverage against HBV in children in Brazzaville. Patients and Methods: This was a cross-sectional analytical study conducted in Brazzaville health centres from January to September 2019. It involved children aged between six months and six years who received a vaccination against HBV. Sampling was exhaustive and based on stratified sampling. Results: The overall prevalence of children vaccinated against HBV in Brazzaville was 96.2%. It was insufficient in the Talangai health district (79%). The pentavalent vaccine was administered to 97.7% of children, 85% of whom had received all three doses. The reasons for incomplete vaccination were parents’ ignorance of HVB (85.6%) and of vaccination (14.3%). Conclusion: Although the prevalence of vaccinated children is high in Brazzaville, it is still insufficient in some health districts, particularly Talangai, because parents are unaware of the disease and of vaccination. Pentavalent is the only vaccine available in the national vaccination programme, which is why an effective national vaccination policy needs to be put in place. . 展开更多
