Cases diagnosed with HBs Ag(-) and HBc Ab(+) liver cancer were included in the HBs Ag seroclearance(SC) group. HBs Ag(+) liver cancer patients strictly matched for liver cancer stage(AJCC staging system, 8 th edition), Child-Pugh score, and first diagnosis/treatment method(surgery, ablation and TACE) were assigned to the HBsA g non-seroclearance(NSC) group. Then, clinical, pathological and survival data in both groups were assessed.RESULTS The SC and NSC groups comprised of 72 and 216 patients, respectively. Patient age(P < 0.001) and platelet count(P = 0.001) in the SC group were significantly higher than those of the NSC group. SC group patients who underwent surgery had more intrahepatic cholangiocarcinoma(ICC) and combined HCC-CC(CHC) cases than the NSC group, but no significant differences in tumor cell differentiation and history of liver cirrhosis were found between the two groups. The numbers of interventional treatments were similar in both groups(4.57 vs 5.07, P > 0.05). Overall survival was lower in the SC group than the NSC group(P = 0.019), with 1-,3-, and 5-year survival rates of 82.1% vs 85.1%, 43.2%vs 56.8%, and 27.0% vs 45.2%, respectively. Survival of patients with AJCC stage Ⅰ disease in the SC group was lower than that of the NSC group(P = 0.029).CONCLUSION Seroclearance in patients with hepatitis B-related primary liver cancer has protective effects with respect to tumorigenesis, cirrhosis, and portal hypertension but confers worse prognosis, which may be due to the frequent occurrence of highly malignant ICC and CHC.展开更多

Among 41 tree shrews exposed to AFB1, 17 were experimentally infected by HHBV and 24 were uninfected. After 158 weeks, significant difference of primary liver cancer (PLC) incidence was present between the HHBV infected (52.94%) and uninfected (12.5%) groups (p<0.05). No difference was found between these two groups in the amount of AFB4 ingestion. Moreover, 1/9 of the tree shrews infected only by HHBV but not exposed to AFB4 developed PLC. No PLC was found in 6 tree shrews that had neither been infected with HHBV nor been exposed to AFB4. These results suggest the possible etiologic relationship between HHBV infection and PLC, as well as the synergetic effects of HHBV and AFB4 during PLC development.展开更多

The Barcelona Clinic Liver Cancer classification is used to guide the treatment of hepatocellular carcinoma. The aim of this retrospective study was to describe the Barcelona Clinic Liver Cancer classification and the treatment of hepatocellular carcinoma in a University Hospital in Côte d’Ivoire. Methods: Patients with hepatocellular carcinoma hospitalized in the hepato-gastroenterology unit of the University Hospital of Yopougon from 01 January 2012 to 30 June 2017 were included. The diagnosis of hepatocellular carcinoma was based on the presence of hepatic nodules on the abdominal ultrasound scan, typical images with the helical scanner associated or not with an increase of the α-fetoprotein higher than 200 ng/ml or with histology. Demographic, clinical, biological and radiological data were determined at the time of diagnosis. Patients were classified according to the Barcelona Clinic Liver Cancer classification. Their treatment was specified. Results: There were 258 patients whose median age was 48.1 years. Viral hepatitis B virus was the primary cause of hepatocellular carcinoma in 64.7% of cases. The severity of the underlying cirrhosis was Child-Pugh A in 12.1%, B in 63.6% and C in 24.3% of cases. The median size of the tumor was 63 mm. The α-fetoprotein level was higher than 200 mg/ml in 56.03% of cases. The Eastern Cooperative Oncology Group (ECOG)/World Health Organization (WHO) system was ≥2 in 82.9%. The Barcelona Clinic Liver Cancer classification was A in 1.3%, B in 0%, C in 55.2% and D in 43.5% of patients. There was no transplantation or hepatic resection. Very few patients (1.9%) received radio-frequency curative therapy. The treatment was predominantly symptomatic in 97.8% of patients. During hospitalization 43.7% of patients died. Conclusion: Hepatocellular carcinoma occurs on a liver with severe cirrhosis at a late stage. This does not allow cure treatment and explains a high mortality rate during hospitalization. Hepatitis B virus is the main risk factor and immunization at birth will reduce the incidence of this cancer in Africa.展开更多
This review describes woodchucks chronically infected with the woodchuck hepatitis virus(WHV)as an animal model for hepatocarcinogenesis and treatment of primary liver cancer or hepatocellular carcinoma(HCC)induced by...This review describes woodchucks chronically infected with the woodchuck hepatitis virus(WHV)as an animal model for hepatocarcinogenesis and treatment of primary liver cancer or hepatocellular carcinoma(HCC)induced by the hepatitis B virus(HBV).Since laboratory animal models susceptible to HBV infection are limited,woodchucks experimentally infected with WHV,a hepatitis virus closely related to HBV,are increasingly used to enhance our understanding of virus-host interactions,immune response,and liver disease progression.A correlation of severe liver pathogenesis with high-level viral replication and deficient antiviral immunity has been established,which are present during chronic infection after WHV inoculation of neonatal woodchucks for modeling vertical HBV transmission in humans.HCC in chronic carrier woodchucks develops 17 to 36 mo after neonatal WHV infection and involves liver tumors that are comparable in size,morphology,and molecular gene signature to those of HBV-infected patients.Accordingly,woodchucks with WHV-induced liver tumors have been used for the improvement of imaging and ablation techniques of human HCC.In addition,drug efficacy studies in woodchucks with chronic WHV infection have revealed that prolonged treatment with nucleos(t)ide analogs,alone or in combination with other compounds,minimizes the risk of liver disease progression to HCC.More recently,woodchucks have been utilized in the delineation of mechanisms involved in innate and adaptive immune responses against WHV during acute,self-limited and chronic infections.Therapeutic interventions based on modulating the deficient host antiviral immunity have been explored in woodchucks for inducing functional cure in HBV-infected patients and for reducing or even delaying associated liver disease sequelae,including the onset of HCC.Therefore,woodchucks with chronic WHV infection constitute a well-characterized,fully immunocompetent animal model for HBV-induced liver cancer and for preclinical evaluation of the safety and efficacy of new modalities,which are based on chemo,gene,and immune therapy,for the prevention and treatment of HCC in patients for which current treatment options are dismal.展开更多

The clinical and paraclinical data used in this description are from patients infected by viral hepatitis B and C of the HOSCO Hepato-Gastroenterological Department from May 15, 2021 to July 23, 2021. The informed consent was provided to each patient included in this study. “Univariate analyses were evaluated using Pearson’s Chi2 test” using R software version 4.0.2. During the study period, we identified 149 patients with viral hepatitis B and/or C who met our inclusion criteria. The sex ratio was 0.83 at the rate of 68 men for 81 women with the average age at 37.17 years ± 12.21 years. The most represented age group was 30 - 44 years (49.7%). The most incriminated risk factors were medical care by injection (62.58%), excision (31.90%), blood transfusion (4.29%) and scarification (1.23%). HBV infection was the majority with a frequency of 95.97%. The HBV viral load was measured in 91.95% of patients, 77.18% of whom had a detectable DNA viral load ≤ 2000 IU/mL. The clinical and biological course was good in patients after therapeutic initiation. HBV-HCV-HIV co-infection was 0.67%. Abdominal ultrasound was normal in 87.92% of patients. Fibrosis was minimal and moderate in 58.39% and 19.46% of patients. Among patients, 52.35% were on Tenofovir therapy, 2.68% on Sofosbuvir/Velpatasvir, 0.67% on ARVs and 44.29% did not require treatment. Viral hepatitis B and C are common, and both affect sex. Thus, new screening strategies need to be implemented to improve the diagnosis of hepatitis B and C. Effective strategies against viral hepatitis B and C must be developed, subsequently.展开更多

METHODS: We investigated 264 liver cirrhosis pa-tients who were not treated with antiviral drugs, in-cluding 81 patients with HCC. YMDD mutations were detected by fluorescent hybridization bioprobe poly-merase chain reaction (PCR) and melting curve assay using the Diagnosis Kit for HBV YMDD Mutation. Serum HBV genotypes were detected by real-time PCR using genotype-specific TaqMan probes. Statistical analysis was performed according to data type using the t test, χ2 test and unconditional logistic regression analysis. RESULTS: In the HCC group, genotype C strains, spon-taneous YMDD mutations, and genotype C strains with YMDD mutations were detected in 33 (40.74%), 13 (16.05%) and 11 (13.58%) patients, respectively. In the liver cirrhosis (LC) group, HBV genotype C strains,spontaneous YMDD mutations, and genotype C strains with YMDD mutations were detected in 33 (18.03%), 7 (3.83%) and 2 (1.09%) patients, respectively. The dif-ferences in genotype C strains, spontaneous YMDD mu-tations, and genotype C strains with YMDD mutations between the two groups were statistically significant (χ2=15.441, P=0.000; χ2=11.983, P=0.001; P=0.000). In the HCC and LC groups, there were seven patients infected by genotype B strains with YMDD mutations and 13 by genotype C strains with YMDD mutations. Further research revealed that HCC oc-curred in 2 patients infected by genotype B strains with YMDD mutations and 11 infected by genotype C strains with YMDD mutations. The difference was statistically significant (P=0.000). Unconditional logistic regres-sion analysis revealed that patients infected by geno-type C strains with spontaneous YMDD mutations had a 7.775-fold higher risk for the development of HBV-related HCC than patients infected by other type HBV strains (P=0.013, 95%CI: 1.540-39.264). CONCLUSION: Genotype C strains with spontaneous YMDD mutations are an independent risk factor for HCC in LC patients and are important for early warning of HCC.展开更多

The estab...Qidong(Jiangsu, China) has been of interest to cancer epidemiologists and biologists because, until recently, it was an endemic area for liver cancer, having amongst the highest incidence rates in the world. The establishment of the Qidong Cancer Registry together with the Qidong Liver Cancer Institute in 1972 has charted the patterns of liver cancer incidence and mortality in a stable population throughout a period of enormous economic, social, and environmental changes as well as of improvements in health care delivery. Updated incidence trends in Qidong are described. Notably, the China age-standardized incidence rate for liver cancer has dropped by over 50% in the past several decades. Molecular epidemiologic and genomic deep sequencing studies have affirmed that infection with hepatitis B virus as well as dietary exposure to aflatoxins through contamination of dietary staples such as corn, and to microcystins–blue-green algal toxins found in ditch and pond water – were likely important etiologic factors that account for the high incidence of liver cancer in this region. Public health initiatives to facilitate universal vaccination of newborns against HBV and to improve drinking water sources in this rural area, as well as economic and social mandates serendipitously facilitating dietary diversity, have led to precipitous declines in exposures to these etiologic factors, concomitantly driving substantive declines in the liver cancer incidence seen now in Qidong. In this regard, Qidong serves as a template for the global impact that a package of intervention strategies may exert on cancer burden.展开更多

文摘BACKGROUND The relationship between hepatitis B surface antigen(HBsAg)-positive carrier status and liver cancer has been extensively studied.However,the epigenetic changes that occur during progression from HBsAg-positive carrier status or cirrhosis to liver cancer are unknown.The epigenetic modification of DNA hydroxymethylation is critical in tumor development.Further,5-hydroxymethylcytosine(5hmC)is an important base for DNA demethylation and epigenetic regulation.It is also involved in the assembly of chromosomes and the regulation of gene expression.However,the mechanism of action of 5hmC in HBsAgpositive carriers or patients with cirrhosis who develop liver cancer has not been fully elucidated.AIM To investigate the possible epigenetic mechanism of HBsAg-positive carriers and hepatocellular carcinoma(HCC)progression from cirrhosis.METHODS Forty HBsAg-positive carriers,forty patients with liver cirrhosis,and forty patients with liver cancer admitted to the First People's Hospital of Yongkang between March 2020 and November 2021 were selected as participants.Free DNA was extracted using a cf-DNA kit.cfDNA was extracted by 5hmC DNA sequencing for principal component analysis,the expression profiles of the three groups of samples were detected,and the differentially expressed genes(DEGs)modified by hydroxymethylation were screened.Bioinformatic analysis was used to enrich DEGs,such as in biological pathways.RESULTS A total of 16455 hydroxymethylated genes were identified.Sequencing results showed that 32 genes had significant 5hmC modification differences between HBsAg carriers and liver cancer patients,of which 30 were upregulated and 2 downregulated in patients with HCC compared with HBsAg-positive carriers.Significant 5hmC modification differences between liver cirrhosis and liver cancer patients were identified in 20 genes,of which 17 were upregulated and 3 were downregulated in patients with HCC compared with those with cirrhosis.These genes may have potential loci that are undiscovered or unelucidated,which contribute to the development and progression of liver cancer.Analysis of gene ontology enrichment and Kyoto Encyclopedia of Genes and Genomes showed that the major signaling pathways involved in the differential genes were biliary secretion and insulin secretion.The analysis of protein interactions showed that the important genes in the protein-protein interaction network were phosphoenolpyruvate carboxykinase and solute carrier family 2.CONCLUSION The occurrence and development of liver cancer involves multiple genes and pathways,which may be potential targets for preventing hepatitis B carriers from developing liver cancer.

文摘BACKGROUND The incidence and mortality of liver cancer are among the highest of all malignant tumors in China.The high recurrence rate after conventional hepatectomy is worrying.There is a lack of effective prognostic indicators for liver cancer.AIM To explore the clinical significance of preoperative serum oxidative stress and serum uric acid(UA)levels in hepatitis B-related liver cancer.METHODS The medical records of 110 hepatitis B-related liver cancer patients who under-went hepatectomy in Gansu Provincial Hospital were retrospectively analyzed.Recurrence in patients within 3 years after surgery was determined.The logistic regression model and Pearson or Spearman correlation were used to analyze the correlation between oxidative stress level and UA,and the recurrence of hepatitis B-related liver cancer.RESULTS Compared with the non-recurrence group,the levels of superoxide dismutase(SOD)and glutathione(GSH)in the recurrence group were lower and the levels of malondialdehyde(MDA)and UA were higher(all P<0.05).UA,SOD,MDA,and GSH were risk factors for postoperative recurrence in hepatitis B-related liver cancer patients(P<0.05).UA was positively correlated with MDA(r=0.395,P<0.001)and negatively correlated with GSH(r=-0.204,P=0.032).The area under the receiver operating characteristic curve(AUC)of SOD,MDA,GSH,and UA in predicting the prognosis was 0.276,0.910,0.199,and 0.784,respectively(all P<0.001).CONCLUSION The preoperative serum SOD,GSH,MDA,and UA levels had significant predictive effects on postoperative recurrence of hepatitis B-related liver cancer.

文摘AIM To assess the impact of hepatitis B surface(HBs Ag) seroclearance on survival outcomes in hepatitis B-related primary liver cancer.METHODS Information from patients with hepatitis B-related liver cancer admitted in our hospital from 2008-2017 was retrieved. Cases diagnosed with HBs Ag(-) and HBc Ab(+) liver cancer were included in the HBs Ag seroclearance(SC) group. HBs Ag(+) liver cancer patients strictly matched for liver cancer stage(AJCC staging system, 8 th edition), Child-Pugh score, and first diagnosis/treatment method(surgery, ablation and TACE) were assigned to the HBsA g non-seroclearance(NSC) group. Then, clinical, pathological and survival data in both groups were assessed.RESULTS The SC and NSC groups comprised of 72 and 216 patients, respectively. Patient age(P < 0.001) and platelet count(P = 0.001) in the SC group were significantly higher than those of the NSC group. SC group patients who underwent surgery had more intrahepatic cholangiocarcinoma(ICC) and combined HCC-CC(CHC) cases than the NSC group, but no significant differences in tumor cell differentiation and history of liver cirrhosis were found between the two groups. The numbers of interventional treatments were similar in both groups(4.57 vs 5.07, P > 0.05). Overall survival was lower in the SC group than the NSC group(P = 0.019), with 1-,3-, and 5-year survival rates of 82.1% vs 85.1%, 43.2%vs 56.8%, and 27.0% vs 45.2%, respectively. Survival of patients with AJCC stage Ⅰ disease in the SC group was lower than that of the NSC group(P = 0.029).CONCLUSION Seroclearance in patients with hepatitis B-related primary liver cancer has protective effects with respect to tumorigenesis, cirrhosis, and portal hypertension but confers worse prognosis, which may be due to the frequent occurrence of highly malignant ICC and CHC.

文摘Background:Hepatitis B virus-related acute-on-chronic liver failure(HBV-ACLF)has a high short-term mortality.However,the treatment progression for HBV-ACLF in China in the past decade has not been well characterized.The present study aimed to determine whether the HBV-ACLF treatment has significantly improved during the past decade.Methods:This study retrospectively compared short-term(28/56 days)survival rates of two different nationwide cohorts(cohort I:2008-2011 and cohort II:2012-2015).Eligible HBV-ACLF patients were enrolled retrospectively.Patients in the cohorts I and II were assigned either to the standard medical therapy(SMT)group(cohort I-SMT,cohort II-SMT)or artificial liver support system(ALSS)group(cohort IALSS,cohort II-ALSS).Propensity score matching analysis was conducted to eliminate baseline differences,and multivariate logistic regression analysis was used to explore the independent factors for 28-day survival.Results:Short-term(28/56 days)survival rates were significantly higher in the ALSS group than those in the SMT group(P<0.05)and were higher in the cohort II than those in the cohort I(P<0.001).After propensity score matching,short-term(28/56 days)survival rates were higher in the cohort II than those in the cohort I for both SMT(60.7%vs.53.0%,50.0%vs.39.8%,P<0.05)and ALSS(66.1%vs.56.5%,53.0%vs.44.4%,P<0.05)treatments.The 28-day survival rate was higher in patients treated with nucleos(t)ide analogs than in patients without such treatments(P=0.046).Multivariate logistic regression analysis revealed that ALSS(OR=0.962,95%CI:0.951-0.973,P=0.038),nucleos(t)ide analogs(OR=0.927,95%CI:0.871-0.983,P=0.046),old age(OR=1.028,95%CI:1.015-1.041,P<0.001),total bilirubin(OR=1.002,95%CI:1.001-1.003,P=0.004),INR(OR=1.569,95%CI:1.044-2.358,P<0.001),COSSH-ACLF grade(OR=2.683,95%CI:1.792-4.017,P<0.001),and albumin(OR=0.952,95%CI:0.924-0.982,P=0.002)were independent factors for 28-day mortality.Conclusions:The treatment for patients with HBV-ACLF has improved in the past decade.
文摘On the basis of the successful establishment of an animal model in tree shrews experimentally in fected with human hepatitis B virus (HHBV), a study on the hepatocarcinogenic effects of HHBV and aflatoxin B1 (AFB1) by using this animal model was conducted through a lifelong experiment. Among 41 tree shrews exposed to AFB1, 17 were experimentally infected by HHBV and 24 were uninfected. After 158 weeks, significant difference of primary liver cancer (PLC) incidence was present between the HHBV infected (52.94%) and uninfected (12.5%) groups (p<0.05). No difference was found between these two groups in the amount of AFB4 ingestion. Moreover, 1/9 of the tree shrews infected only by HHBV but not exposed to AFB4 developed PLC. No PLC was found in 6 tree shrews that had neither been infected with HHBV nor been exposed to AFB4. These results suggest the possible etiologic relationship between HHBV infection and PLC, as well as the synergetic effects of HHBV and AFB4 during PLC development.
文摘Context/Objectives: Hepatocellular carcinoma occurs mainly and increasingly in developing countries, where the prognosis is particularly poor. The Barcelona Clinic Liver Cancer classification is used to guide the treatment of hepatocellular carcinoma. The aim of this retrospective study was to describe the Barcelona Clinic Liver Cancer classification and the treatment of hepatocellular carcinoma in a University Hospital in Côte d’Ivoire. Methods: Patients with hepatocellular carcinoma hospitalized in the hepato-gastroenterology unit of the University Hospital of Yopougon from 01 January 2012 to 30 June 2017 were included. The diagnosis of hepatocellular carcinoma was based on the presence of hepatic nodules on the abdominal ultrasound scan, typical images with the helical scanner associated or not with an increase of the α-fetoprotein higher than 200 ng/ml or with histology. Demographic, clinical, biological and radiological data were determined at the time of diagnosis. Patients were classified according to the Barcelona Clinic Liver Cancer classification. Their treatment was specified. Results: There were 258 patients whose median age was 48.1 years. Viral hepatitis B virus was the primary cause of hepatocellular carcinoma in 64.7% of cases. The severity of the underlying cirrhosis was Child-Pugh A in 12.1%, B in 63.6% and C in 24.3% of cases. The median size of the tumor was 63 mm. The α-fetoprotein level was higher than 200 mg/ml in 56.03% of cases. The Eastern Cooperative Oncology Group (ECOG)/World Health Organization (WHO) system was ≥2 in 82.9%. The Barcelona Clinic Liver Cancer classification was A in 1.3%, B in 0%, C in 55.2% and D in 43.5% of patients. There was no transplantation or hepatic resection. Very few patients (1.9%) received radio-frequency curative therapy. The treatment was predominantly symptomatic in 97.8% of patients. During hospitalization 43.7% of patients died. Conclusion: Hepatocellular carcinoma occurs on a liver with severe cirrhosis at a late stage. This does not allow cure treatment and explains a high mortality rate during hospitalization. Hepatitis B virus is the main risk factor and immunization at birth will reduce the incidence of this cancer in Africa.
文摘This review describes woodchucks chronically infected with the woodchuck hepatitis virus(WHV)as an animal model for hepatocarcinogenesis and treatment of primary liver cancer or hepatocellular carcinoma(HCC)induced by the hepatitis B virus(HBV).Since laboratory animal models susceptible to HBV infection are limited,woodchucks experimentally infected with WHV,a hepatitis virus closely related to HBV,are increasingly used to enhance our understanding of virus-host interactions,immune response,and liver disease progression.A correlation of severe liver pathogenesis with high-level viral replication and deficient antiviral immunity has been established,which are present during chronic infection after WHV inoculation of neonatal woodchucks for modeling vertical HBV transmission in humans.HCC in chronic carrier woodchucks develops 17 to 36 mo after neonatal WHV infection and involves liver tumors that are comparable in size,morphology,and molecular gene signature to those of HBV-infected patients.Accordingly,woodchucks with WHV-induced liver tumors have been used for the improvement of imaging and ablation techniques of human HCC.In addition,drug efficacy studies in woodchucks with chronic WHV infection have revealed that prolonged treatment with nucleos(t)ide analogs,alone or in combination with other compounds,minimizes the risk of liver disease progression to HCC.More recently,woodchucks have been utilized in the delineation of mechanisms involved in innate and adaptive immune responses against WHV during acute,self-limited and chronic infections.Therapeutic interventions based on modulating the deficient host antiviral immunity have been explored in woodchucks for inducing functional cure in HBV-infected patients and for reducing or even delaying associated liver disease sequelae,including the onset of HCC.Therefore,woodchucks with chronic WHV infection constitute a well-characterized,fully immunocompetent animal model for HBV-induced liver cancer and for preclinical evaluation of the safety and efficacy of new modalities,which are based on chemo,gene,and immune therapy,for the prevention and treatment of HCC in patients for which current treatment options are dismal.
文摘Objective:The purpose of this study was to analyze risk factors for development of post-hepatectomy liver dysfunction in primary liver cancer(PLC)patients with concurrent hepatic schistosomiasis and chronic hepatitis.Methods:A retrospective analysis of 73 PLC patients with concurrent hepatic schistosomiasis and chronic hepatitis,of which 16 patients developed liver dysfunction(persistent ascites or pleural effusion or occurrence of liver-related potentially fatal complications)following hepatectomy,was performed.After clinical characteristics were recorded,preoperative liver function parameters and surgery-related parameters in these patients were assessed.Seventeen potential risk factors for post-hepatectomy liver dysfunction were identified.The association between these potential risk factors and post-hepatectomy liver dysfunction then was analyzed.Results:Univariate analysis showed that liver cirrhosis,intraoperative blood loss,and preoperative total bilirubin were associated with the development of post-hepatectomy liver dysfunction.Multivariate logistic regression analysis of these three factors revealed that intraoperative blood loss≥600 mL and cirrhosis were two independent risk factors for post-hepatectomy liver dysfunction in PLC patients with concurrent hepatic schistosomiasis and chronic hepatitis.Conclusion:Keeping intraoperative blood loss below 600 mL can help avoid the development of post-hepatectomy liver dysfunction in liver cancer patients with concurrent hepatic schistosomiasis and chronic hepatitis.For patients with concomitant liver cirrhosis,every effort should be made to minimize potential liver function impairment induced by other adverse factors.
文摘The present study aims to describe the clinical and paraclinical profile of patients infected by viral hepatitis B and C and follow-up. The clinical and paraclinical data used in this description are from patients infected by viral hepatitis B and C of the HOSCO Hepato-Gastroenterological Department from May 15, 2021 to July 23, 2021. The informed consent was provided to each patient included in this study. “Univariate analyses were evaluated using Pearson’s Chi2 test” using R software version 4.0.2. During the study period, we identified 149 patients with viral hepatitis B and/or C who met our inclusion criteria. The sex ratio was 0.83 at the rate of 68 men for 81 women with the average age at 37.17 years ± 12.21 years. The most represented age group was 30 - 44 years (49.7%). The most incriminated risk factors were medical care by injection (62.58%), excision (31.90%), blood transfusion (4.29%) and scarification (1.23%). HBV infection was the majority with a frequency of 95.97%. The HBV viral load was measured in 91.95% of patients, 77.18% of whom had a detectable DNA viral load ≤ 2000 IU/mL. The clinical and biological course was good in patients after therapeutic initiation. HBV-HCV-HIV co-infection was 0.67%. Abdominal ultrasound was normal in 87.92% of patients. Fibrosis was minimal and moderate in 58.39% and 19.46% of patients. Among patients, 52.35% were on Tenofovir therapy, 2.68% on Sofosbuvir/Velpatasvir, 0.67% on ARVs and 44.29% did not require treatment. Viral hepatitis B and C are common, and both affect sex. Thus, new screening strategies need to be implemented to improve the diagnosis of hepatitis B and C. Effective strategies against viral hepatitis B and C must be developed, subsequently.

文摘BACKGROUND Primary liver cancer(PLC)is a major contributor to cancer-related deaths.Data on global and country-specific levels and trends of PLC are essential for understanding the effects of this disease and helping policymakers to allocate resources.AIM To investigate the association between the burden of PLC and socioeconomic development status.METHODS Cancer mortality and incidence rates were obtained from the Global Burden of Disease(GBD)2019,and the data were stratified by country and territory,sex,and the Socio-demographic Index(SDI)level.The association between the attributable etiology of PLC and socioeconomic development status,represented using the SDI,was described.The attributable etiology of PLC included hepatitis B,hepatitis C,alcohol use,and nonalcoholic steatohepatitis.The association between the attributable etiology of PLC and SDI was further stratified by sex and geographical location.A confidence analysis was also performed based on bootstrap draw.RESULTS The age-standardized incidence rate of PLC was 6.5[95%confidence intervals(CI):5.9-7.2]per 100000 person-years,which decreased by-27.5%(-37.0 to-16.6)from 1990 to 2019.Several countries located in East Asia,South Asia,West Africa,and North Africa shouldered the heaviest burden of PLC in 2019.In terms of incidence rates,the first leading underlying cause of PLC identified was hepatitis B,followed by hepatitis C,alcohol use,and nonalcoholic steatohepatitis.Regarding stratification using the SDI,the incidence rate of PLC was the highest for high and middle SDI locations.Further,the leading attributable etiologies of PLC were hepatitis B for the middle and high middle SDI locations while hepatitis C and nonalcoholic steatohepatitis for the high SDI locations.CONCLUSION The pronounced association between socioeconomic development status and PLC burden indicates socioeconomic development status affects attributable etiologies for PLC.GBD 2019 data are valuable for policymakers implementing PLC cost-effective interventions.
文摘Since molecules with direct-acting antiviral(DAA)became available,the landscape of the treatment of hepatitis C virus(HCV)infection has completely changed.The new drugs are extremely effective in eradicating infection,and treatment is very well tolerated with a duration of 8-12 wk.This review aims to report the outstanding clinical benefits of DAA and to highlight their critical disadvantages,identifying some clinically relevant hot topics.First,do the rates of virological response remain as high when patients with more advanced cirrhosis are considered?Large studies have shown slightly lower but still satisfactory rates of response in these patients.Nevertheless,modified schedules with an extended treatment duration and use of ribavirin may be necessary.Second,does the treatment of HCV infection affect the risk of occurrence and recurrence of liver cancer?Incidence is reduced after viral eradication but remains high enough to warrant periodic surveillance for an early diagnosis.In contrast,the risk of recurrence seems to be unaffected by viral clearance;however,DAA treatment improves survival because of the reduced risk of progression of liver disease.Third,can HCV treatment also have favorable effects on major comorbidities?HCV eradication is associated with a reduced incidence of diabetes,an improvement in glycemic control and a decreased risk of cardiovascular events;nevertheless,a risk of hypoglycemia during DAA treatment has been reported.Finally,is it safe to treat patients with HCV/hepatitis B virus(HBV)coinfection?In this setting,HCV is usually the main driver of viral activity,while HBV replication is suppressed.Because various studies have described HBV reactivation after HCV clearance,a baseline evaluation for HBV coinfection and a specific follow-up is mandatory.
文摘Fifteen patients with unresectable hepatocellular carcinoma were treated with unresectable hepatocellular carcinoma were treated with high dose MMC or ADR via hepatic artery with drug filtration in our hospital from April to December 1988. Among them, 11 cases (73%) had symptoms relief, 3 cases (20%) tumor minimal remission and AFP decreased in 4 cases (33%). One case dide of hep'atoma 8 months after HAI-F and another case was followed up only 2 months after treatment, the remaining 13 cases are alive for 5 to 10 months after HAI-F.

文摘AIM: To investigate the relationship between hepatitis B virus (HBV) genotype with spontaneous YMDD mu-tations and hepatocellular carcinoma (HCC) in HBV-related cirrhosis. METHODS: We investigated 264 liver cirrhosis pa-tients who were not treated with antiviral drugs, in-cluding 81 patients with HCC. YMDD mutations were detected by fluorescent hybridization bioprobe poly-merase chain reaction (PCR) and melting curve assay using the Diagnosis Kit for HBV YMDD Mutation. Serum HBV genotypes were detected by real-time PCR using genotype-specific TaqMan probes. Statistical analysis was performed according to data type using the t test, χ2 test and unconditional logistic regression analysis. RESULTS: In the HCC group, genotype C strains, spon-taneous YMDD mutations, and genotype C strains with YMDD mutations were detected in 33 (40.74%), 13 (16.05%) and 11 (13.58%) patients, respectively. In the liver cirrhosis (LC) group, HBV genotype C strains,spontaneous YMDD mutations, and genotype C strains with YMDD mutations were detected in 33 (18.03%), 7 (3.83%) and 2 (1.09%) patients, respectively. The dif-ferences in genotype C strains, spontaneous YMDD mu-tations, and genotype C strains with YMDD mutations between the two groups were statistically significant (χ2=15.441, P=0.000; χ2=11.983, P=0.001; P=0.000). In the HCC and LC groups, there were seven patients infected by genotype B strains with YMDD mutations and 13 by genotype C strains with YMDD mutations. Further research revealed that HCC oc-curred in 2 patients infected by genotype B strains with YMDD mutations and 11 infected by genotype C strains with YMDD mutations. The difference was statistically significant (P=0.000). Unconditional logistic regres-sion analysis revealed that patients infected by geno-type C strains with spontaneous YMDD mutations had a 7.775-fold higher risk for the development of HBV-related HCC than patients infected by other type HBV strains (P=0.013, 95%CI: 1.540-39.264). CONCLUSION: Genotype C strains with spontaneous YMDD mutations are an independent risk factor for HCC in LC patients and are important for early warning of HCC.
文摘Abnormal liver biochemical tests are present in up to30%of patients with inflammatory bowel disease(IBD),and therefore become a diagnostic challenge.Liver and biliary tract diseases are common extraintestinal manifestations for both Crohn’s disease and ulcerative colitis(UC),and typically do not correlate with intestinal activity.Primary sclerosing cholangitis(PSC)is the most common hepatobiliary manifestation of IBD,and is more prevalent in UC.Approximately 5%of patients with UC develop PSC,with the prevalence reaching up to 90%.Cholangiocarcinoma and colon cancer risks are increased in these patients.Less common disorders include autoimmune hepatitis/PSC overlap syndrome,IgG4-associated cholangiopathy,primary biliary cirrhosis,hepatic amyloidosis,granulomatous hepatitis,cholelithiasis,portal vein thrombosis,liver abscess,and non-alcoholic fatty liver disease.Hepatitis B reactivation during immunosuppressive therapy is a major concern,with screening and vaccination being recommended in serologically negative cases for patients with IBD.Reactivation prophylaxis with entecavir or tenofovir for 6to 12 mo after the end of immunosuppressive therapy is mandatory in patients showing as hepatitis B surface antigen(HBsAg)positive,independently from viral load.HBsAg negative and anti-HBc positive patients,with or without anti-HBs,should be closely monitored,measuring alanine aminotransferase and hepatitis B virus DNA within 12 mo after the end of therapy,and should be treated if the viral load increases.On the other hand,immunosuppressive therapy does not seem to promote reactivation of hepatitis C,and hepatitis C antiviral treatment does not influence IBD natural history either.Most of the drugs used for IBD treatment may induce hepatotoxicity,although the incidence of serious adverse events is low.Abnormalities in liver biochemical tests associated with aminosalicylates are uncommon and are usually not clinically relevant.Methotrexaterelated hepatotoxicity has been described in 14%of patients with IBD,in a dose-dependent manner.Liver biopsy is not routinely recommended.Biologics-related hepatotoxicity is rare,but has been shown most frequently in patients treated with infliximab.Thiopurines have been associated with veno-occlusive disease,regenerative nodular hyperplasia,and liver peliosis.Routine liver biochemical tests are recommended,especially during the first month of treatment.All these conditions should be considered in IBD patients with clinical or biochemical features suggestive of hepatobiliary involvement.Diagnosis and management of these disorders usually involve hepatologists and gastroenterologists due to its complexity.

文摘Qidong(Jiangsu, China) has been of interest to cancer epidemiologists and biologists because, until recently, it was an endemic area for liver cancer, having amongst the highest incidence rates in the world. The establishment of the Qidong Cancer Registry together with the Qidong Liver Cancer Institute in 1972 has charted the patterns of liver cancer incidence and mortality in a stable population throughout a period of enormous economic, social, and environmental changes as well as of improvements in health care delivery. Updated incidence trends in Qidong are described. Notably, the China age-standardized incidence rate for liver cancer has dropped by over 50% in the past several decades. Molecular epidemiologic and genomic deep sequencing studies have affirmed that infection with hepatitis B virus as well as dietary exposure to aflatoxins through contamination of dietary staples such as corn, and to microcystins–blue-green algal toxins found in ditch and pond water – were likely important etiologic factors that account for the high incidence of liver cancer in this region. Public health initiatives to facilitate universal vaccination of newborns against HBV and to improve drinking water sources in this rural area, as well as economic and social mandates serendipitously facilitating dietary diversity, have led to precipitous declines in exposures to these etiologic factors, concomitantly driving substantive declines in the liver cancer incidence seen now in Qidong. In this regard, Qidong serves as a template for the global impact that a package of intervention strategies may exert on cancer burden.
