文摘BACKGROUND Rhabdomyosarcoma(RMS)is a type of malignant tumor originating from rhabdomyocytes or mesenchymal cells differentiating into rhabdomyocytes.Hepatic pleomorphic RMS is a rare malignant liver tumor.Hepatic sarcomatoid carcinoma is also a rare epithelial malignant tumor originating from the liver;it is characterized by the coexistence of both carcinomatous and sarcomatoid spindle cell components.CASE SUMMARY This paper reports a special case of an elderly woman whose initial liver puncture biopsy showed pleomorphic RMS.After chemotherapy with the vincristine+doxorubicin+cyclophosphamide regimen,the alpha-fetoprotein level increased significantly.Therefore,a second liver puncture was performed,the pathological result of which was hepatic sarcomatoid carcinoma.Next-generation sequencing revealed MET gene amplification with an average copy number of 9 in the tumor tissue;however,both fluorescence in situ hybridization and immunohistochemical tests were negative for MET amplification.The treatment regimen was adjusted to chemotherapy combined with immunotherapy;however,the disease progressed rapidly,and the overall survival was only 6 months.CONCLUSION By sharing the diagnosis and treatment process of this patient and reviewing the relevant literature,we aim to help clinicians enhance their understanding of two rare diseases,namely pleomorphic RMS and sarcomatoid carcinoma of the liver.
文摘BACKGROUND Hepatocellular carcinoma(HCC)is a major type of liver cancer worldwide.In advanced stages,portal vein tumor thrombosis(PVTT)and jaundice are common,whereas obstructive jaundice(OJ)is relatively rare.Both conditions markedly reduce survival and increase therapeutic complexity.Recently,hepatic artery infusion chemotherapy(HAIC)in combination with targeted immunotherapy has shown promise for advanced HCC.CASE SUMMARY We report a 47-year-old male with advanced HCC complicated by PVTT and OJ,who was admitted with marked jaundice of the skin and sclera.Imaging revealed a large hepatic mass(14.5 cm×11.3 cm)in the right lobe with associated portal vein tumor thrombus.The tertiary bile duct was only mildly dilated,making percutaneous transhepatic cholangiography drainage infeasible.The patient underwent reduced-dose HAIC,which resulted in significant tumor shrinkage and marked reduction in serum bilirubin.This improvement enabled sequential treatment with lenvatinib and camrelizumab.After six cycles,both liver function and alphafetoprotein levels improved.The patient achieved a progression-free survival of 20 months and an overall survival of 29 months.CONCLUSION HAIC can treat high-bilirubin HCC with PVTT and OJ,allowing for subsequent targeted immunotherapy.

文摘BACKGROUND Laparoscopic liver resection(LLR)can be challenging due to the difficulty of establishing a retrohepatic tunnel under laparoscopy.Dissecting the third hepatic hilum before parenchymal transection often leads to significant liver mobilization,tumor compression,and bleeding from the short hepatic veins(SHVs).This study introduces a novel technique utilizing the ventral avascular area of the inferior vena cava(IVC),allowing SHVs to be addressed after parenchymal transection,thereby reducing surgical complexity and improving outcomes in in situ LLR.AIM To introduce and evaluate a novel LLR technique using the ventral avascular area of the IVC and compare its short-term outcomes with conventional methods.METHODS The clinical cohort data of patients with pathologically confirmed hepatocellular carcinoma or intrahepatic cholangiocarcinoma who underwent conventional LLR and novel LLR between July 2021 and July 2023 at the First Affiliated Hospital of Chongqing Medical University were retrospectively analyzed.In novel LLR,we initially separated the caudate lobe from the IVC using dissecting forceps along the ventral avascular area of the IVC.Then,we transected the parenchyma of the left and right caudate lobes from the caudal side to the cephalic side using the avascular area as a marker.Subsequently,we addressed the SHVs and finally dissected the root of the right hepatic vein or left hepatic vein.The short-term postoperative outcomes and oncological results of the two approaches were evaluated and compared.RESULTS A total of 256 patients were included,with 150(58.59%)undergoing conventional LLR and 106(41.41%)undergoing novel LLR.The novel technique resulted in significantly larger tumor resections(6.47±2.96 cm vs 4.01±2.33 cm,P<0.001),shorter operative times(199.57±60.37 minutes vs 262.33±83.90 minutes,P<0.001),less intraoperative blood loss(206.92±37.09 mL vs 363.34±131.27 mL,P<0.001),and greater resection volume(345.11±31.40 mL vs 264.38±31.98 mL,P<0.001)compared to conventional LLR.CONCLUSION This novel technique enhances liver resection outcomes by reducing intraoperative complications such as bleeding and tumor compression.It facilitates a safer,in situ removal of complex liver tumors,even in challenging anatomical locations.Compared to conventional methods,this technique offers significant advantages,including reduced operative time,blood loss,and improved overall surgical efficiency.
文摘BACKGROUND Transfusion transmissible infections(TTIs)are illnesses spread through contaminated blood or blood products.In India,screening for TTIs such as hepatitis B virus(HBV),hepatitis C virus(HCV),human immunodeficiency virus(HIV)-I/II,malaria,and syphilis is mandatory before blood transfusions.Worldwide,HCV,HBV,and HIV are the leading viruses causing mortality,affecting millions of people globally,including those with co-infections of HIV/HCV and HIV/HBV.Studies highlight the impact of TTIs on life expectancy and health risks,such as liver cirrhosis,cancer,and other diseases in individuals with chronic HBV.Globally,millions of blood donations take place annually,emphasizing the importance of maintaining blood safety.AIM To study the prevalence of TTIs,viz.,HBV,HCV,HIV I/II,syphilis,and malaria parasite(MP),among different blood donor groups.METHODS The study assessed the prevalence of TTIs among different blood donor groups in Delhi,India.Groups included total donors,in-house donors,total camp donors,institutional camp donors,and community camp donors.Tests for HIV,HBV,and HCV were done using enzyme-linked immunosorbent assay,while syphilis was tested with rapid plasma reagins and MP rapid card methods.The prevalence of HBV,HCV,HIV,and syphilis,expressed as percentages.Differences in infection rates between the groups were analyzed usingχ²tests and P-values(less than 0.05).RESULTS The study evaluated TTIs among 42158 blood donors in Delhi.The overall cumulative frequency of TTIs in total blood donors was 2.071%,and the frequencies of HBV,HCV,HIV-I/II,venereal disease research laboratory,and MP were 1.048%,0.425%,0.221%,0.377%,and 0.0024%,respectively.In-house donors,representing 37656 donors,had the highest transfusion transmissible infection(TTI)prevalence at 2.167%.Among total camp donors(4502 donors),TTIs were identified in 1.266%of donors,while community camp donors(2439 donors)exhibited a prevalence of 1.558%.Institutional camp donors(2063 donors)had the lowest TTI prevalence at 0.921%.Statistical analysis revealed significant differences in overall TTI prevalence,with total and in-house donors exhibiting higher rates compared to camp donors.CONCLUSION Ongoing monitoring and effective screening programs are essential for minimizing TTIs.Customizing blood safety measures for different donor groups and studying socio-economic-health factors is essential to improving blood safety.
文摘BACKGROUND Sex is one of the known factors influencing the risk of hepatitis C virus(HCV)infection and the natural course of the disease.AIM To evaluate sex-related differences in the characteristics and outcomes of direct-acting antiviral(DAA)treatment in HCV-infected patients.METHODS The study included consecutive 9457 women and 9529 men,treated with DAA for chronic HCV infection from July 2015 to the end of 2023 whose data were collected in the nationwide multicenter retrospective Epiter-2 project.Women were divided into pre-menopausal(15-44 years),menopausal(45-55 years)and post-menopausal(>55 years)and compared with age-matched men.RESULTS Regardless of age,women had a significantly lower body mass index,prevalence of genotype 3 infection and proportion of cirrhosis compared to men.Psychiatric disorders(except depression),hepatitis B virus and human immunodeficiency virus co-infections,as well as alcohol and drug addiction,were significantly less common in women than in men in all age groups.The sustained virologic response was significantly higher in women compared to men in each age group and amounted to 98.4%and 96.6%,respectively(P<0.001).Independent predictors of treatment failure in women were genotype 3 infection,cirrhosis and postmenopausal age.Mild adverse events were reported significantly more often by women,regardless of age with the highest percentage in the postmenopausal group.CONCLUSION DAA treatment is more effective in women than in men,regardless of age,but in postmenopausal women,the effectiveness is relatively the lowest.
文摘BACKGROUND Autoimmune hepatitis(AIH)is typically treated with immunomodulators and steroids.However,some patients are refractory to these treatments,necessitating alternative approaches.Biological therapies have recently been explored for these difficult cases.AIM To assess the efficacy and safety of biologics in AIH,focusing on patients unresponsive to standard treatments and evaluating outcomes such as serological markers and histological remission.METHODS A case-based systematic review was performed following the PRISMA protocol to evaluate the efficacy and safety of biological therapies in AIH.The primary focus was on serological improvement and histological remission.The secondary focus was on assessing therapy safety and additional outcomes.A standardized search command was applied to MEDLINE,EMBASE,and Cochrane Library databases to identify relevant studies.Inclusion criteria encompassed adult AIH patients treated with biologics.Data were analyzed based on demographics,prior treatments,and therapy-related outcomes.A narrative synthesis was employed to address biases and provide a comprehensive overview of the evidence.RESULTS A total of 352 studies were reviewed,with 30 selected for detailed analysis.Key findings revealed that Belimumab led to a favourable response in five out of eight AIH patients across two studies.Rituximab demonstrated high efficacy,with 41 out of 45 patients showing significant improvement across six studies.Basiliximab was assessed in a single study,where the sole patient treated experienced a beneficial outcome.Additionally,a notable number of AIH cases were induced by anti-tumor necrosis factor(TNF)medications,including 16 cases associated with infliximab and four cases with adalimumab.All these cases showed improvement upon withdrawal of the biologic agent.CONCLUSION Belimumab and Rituximab show promise as effective alternatives for managing refractory AIH,demonstrating significant improvements in clinical outcomes and liver function.However,the variability in patient responses to different therapies highlights the need for personalized treatment strategies.The risk of AIH induced by anti-TNF therapies underscores the need for vigilant monitoring and prompt symptom recognition.These findings support the incorporation of biologic agents into AIH treatment protocols,particularly for patients who do not respond to conventional therapies.
文摘BACKGROUND Clinical guidelines for early extubation after liver transplantation remain lacking,with significant variations in the rates of early extubation across transplantation centers.AIM To identify clinical factors,including the use of epidural analgesia,associated with early extubation in living-donor liver transplantation(LDLT).METHODS The medical records of LDLT recipients were analyzed in this study,categorizing them based on extubation timing as delayed(leaving the operating room without extubation)or early(tracheal tube removed immediately after surgery).A multivariate binary logistic regression analysis was performed.Subgroup analysis was conducted,excluding patients contraindicated for epidural analgesia owing to significant coagulopathy.RESULTS Total of 159 patients,93(58.5%)underwent early extubation.Relevant clinical factors of early extubation were shorter anhepatic time[adjusted odds ratio(OR)=0.439,95%confidence interval(CI):0.232-0.831;P=0.011],absence of high-dose vasoactive drug use at the end of surgery(OR=0.235,95%CI:0.106-0.519;P<0.001),and the use of epidural analgesia(OR=15.730,95%CI:1.919-128.919;P=0.010).In a subgroup analysis of 67 patients,epidural analgesia remained a relevant clinical factor for early extubation(adjusted OR=19.381,95%CI:2.15-174.433;P=0.008).CONCLUSION Shorter anhepatic time,absence of high-dose vasoactive drug use at the end of surgery,and the use of epidural analgesia are relevant clinical factors of early extubation following LDLT.
文摘Kawasaki disease(KD)is a critical pediatric vasculitis with potentially severe cardiovascular outcomes if left untreated.Alanine aminotransferase(ALT)levels,which primarily indicate hepatic injury,are frequently elevated in patients with KD,suggesting systemic inflammation and liver involvement.This editorial explores the multifaceted relationship between KD and ALT elevation,emphasizing the importance of monitoring ALT levels to gauge disease severity and tailor therapeutic interventions.The comprehensive evaluation and integration of ALT monitoring into routine clinical practice can improve patient outcomes by identifying high-risk patients early and guiding timely and appropriate management strategies.
文摘BACKGROUND Steroids remain the primary treatment for severe alcohol-associated hepatitis(AAH),though there is little available tools to predict patient response to steroids.It was hypothesized that phosphatidylethanol(PEth)value will inversely corre-late with response to steroid therapy based on Lille score in AAH.AIM To assess the relationship of patient factors,focusing on pre-steroid therapy PEth value,to steroid therapy response in AAH.METHODS A retrospective case control study was performed on patients who received≥4 days of steroid therapy for AAH at our hospital between July 1,2019 and June 30,2022.A total of 2087 patients were screened for AAH and those treated with steroids were included for statistical analysis utilizing independent sample t-test and for categorical variables using the χ^(2) test.RESULTS No correlation was found between PEth value,pre-steroids abstinence length,or number of drinks per week pre-steroids and response to steroids.Non-responder status significantly correlated with older age(P=0.024),lower albumin(P=0.003),and higher bilirubin(P=0.010)pre-steroids.Our study suggests that age,pre-steroid albumin,and pre-steroid bilirubin levels may predict nonresponse to steroid therapy.Non-responders have increased incidence of death and higher medical costs.CONCLUSION Identifying non-responders through these identified factors should prompt early referral for liver transplantation.Future prospective studies with larger population size are needed to assess the efficacy of combined pre-steroid age,albumin,bilirubin and other biochemical markers as predictors of steroid response.
文摘This letter evaluates Shahid et al’s study in 2025 on the rising hepatitis A virus(HAV)among adults in Pakistan,highlighting a shift in the virus’s epidemiology.Once primarily a childhood disease in low-income regions,HAV is now increasingly affecting adults,also seen globally due to improved sanitation.The study highlights public health challenges from adult HAV infections,which can lead to complications like coagulopathy and acute liver failure.It also has limitations,including being a single-center study and lacking seroprevalence and socioeconomic data,indicating the need for further research.This letter calls for urgent public health measures to extend adult vaccination programs and improve sanitation to address the increasing HAV infection in adult populations.

文摘Background Oxidative stress significantly impacts growth performance and liver function in piglets.Ferulic acid(FA)works as an antioxidant,however,the role and mechanism of FA in the regulation of diquat-induced oxidative stress in piglets are less known.This study was designed to investigate the effects of FA on growth performance and antioxi-dant capacity in piglets with diquat challenge.Methods Thirty-two healthy DLY(Duroc×Landrace×Yorkshire)piglets(13.24±0.19 kg)were randomly divided into one of two diets including 0 or 4 g/kg FA for 14 d.On d 15,all pigs were intraperitoneally injected diquat or sterile saline.Results Dietary supplementation with ferulic acid(FA)significantly improved the average daily gain(ADG)and decreased feed-gain ratio(F/G)of piglets.Here,dietary FA supplementation reduced serum aspartate aminotrans-ferase(AST),alanine aminotransferase(ALT)activities in diquat challenged piglets.Furthermore,diquat infusion increased reactive oxygen radicals(ROS)level in liver,decreased the activities of total superoxide dismutase(T-SOD)and glutathione peroxidase(GSH-Px),total antioxidant capacity(T-AOC)and increased malondialdehyde(MDA)con-tent in the liver and serum.Supplementation with FA significantly increased T-AOC and T-SOD activities and decreased MDA and ROS levels.FA down-regulated gene and protein expression of Keap1,and up-regulated protein expression of Nrf2 and HO-1 in the liver of piglets with diquat challenge.Importantly,diquat challenge increased the ratio of late apoptosis,increased serum levels of IL-1β,IL-18 and lactate dehydrogenase(LDH),and up-regulated pyroptosis-related genes in the liver.FA supplementation reduced the ratio of late apoptosis and down-regulated mRNA expression of Caspase-1.Accordingly,FA addition reduced concentration of IL-1β,IL-18,and LDH under diquat challenge.Conclusions Diquat-induced oxidative stress reduced growth performance and impaired liver function in piglets.Dietary FA supplementation enhanced the antioxidant capacity and reduced the degree of hepatocyte pyroptosis,thereby alleviating the oxidative damage in the liver and mitigating the impact of diquat on growth performance of piglets.
文摘Background:Congenital hepatic hemangioma(CHH)is a rare benign vascular tumor that occurs prenatally.However,only a few cases have been summarized and evaluated for the prenatal and postnatal imaging features of CHH,and no studies have conducted long-term follow-up on it.This study aimed to explore the ultrasound and magnetic resonance features,growth patterns,and clinical outcomes of CHH.Methods:Thirty-six pregnancies with a prenatal fetal diagnosis and postnatal diagnosis of CHH were studied.CHHs were grouped into those with a diameter≥4 cm and those with a diameter<4 cm according to the largest diameter.Fisher's exact test was used to compare the imaging characteristics between the groups.The volume of CHHs was measured at each follow-up visit to plot the growth pattern of the tumors,and the volume of CHHs was compared before and after birth using a rank sum test analysis.Results:Thirty-three cases of CHHs were confirmed by postnatal imaging,and three were confirmed by a biopsy.Mixed echoes were more common in the diameter≥4 cm group than in the diameter<4 cm group(p=0.026).Complications were more likely to occur in the large-diameter group.Eighteen(54.5%)cases were classified as rapidly involuting congenital hemangioma,nine(27.3%)as partially involuting congenital hemangioma,and two(6.1%)as noninvoluting congenital hemangioma.A new type of CHH was identified in which four(12.1%)cases continued to proliferate after birth and spontaneously subsided in subsequent months.The CHH volume decreased with age and was significantly decreased at 9 months postnatal compared to birth(p=0.001).Conclusion:This study showed the imaging features of CHH were associated with the lesion size.Based on postnatal follow-up,a new type of CHH was identified.If there are no complications at birth in CHH cases,a good prognosis is indicated.

文摘BACKGROUND In this study,we are committed to exploring the characteristics of the gut microbiome in three different stages of chronic liver disease(CLD):Chronic hepatitis B,liver cirrhosis,and hepatocellular carcinoma(HCC).AIM To delineate the gut microbiota traits in individuals with chronic liver ailments(chronic hepatitis B,cirrhosis,HCC),scrutinizes microbiome alterations during the progression of these diseases,and assesses microbiome disparities among various Child-Pugh categories in cirrhosis sufferers.METHODS A cohort of 60 CLD patients from the Third People’s Hospital of Yunnan Province were recruited from February to August 2023,together with 37 healthy counterparts.Employing 16SrDNA high-throughput sequencing,we evaluated the diversity and composition of the gut microbiota.RESULTS Compared to healthy subjects,patients exhibited a reduced presence of Firmicutes and a corresponding decline in butyrate-producing genera.In contrast,an upsurge in Proteobacteria was observed in the diseased cohorts,particularly an increase in Enterobacteriaceae that intensified with the disease's progression.At the genus level,the occurrence of Escherichia_Shigella,Parabacteroides,Streptococcus,Klebsiella,and Enterococcus was higher,with Escherichia_Shigella numbers augmenting as the disease advanced.Furthermore,in cirrhosis patients,an increase in CONCLUSION The reduced abundance of short-chain fatty acid-producing bacteria in the intestine,alongside the increased abundance of gram-negative bacteria such as Escherichia_Shigella and Parabacteroides,may promote the progression of CLD.

文摘In this article,we provide commentary on the recent article by Zhao et al.We focus on the shifts in the gut microbiota of patients with hepatitis B virus(HBV)-associated cirrhosis/portal hypertension(PH)following transjugular intrahepatic portosystemic shunt(TIPS)and the implications for understanding the mechanisms,diagnosis,and treatment.By comparing the gut microbiota composition and dynamic changes before and after TIPS in patients with and without hepatic encephalopathy,the authors found an increase in non-probiotic bacteria in those who developed hepatic encephalopathy post-TIPS,with Morganella species present only in the hepatic encephalopathy group.The gut microbiota changes post-TIPS among patients without the occurrence of hepatic encephalopathy suggest potential therapeutic benefits through prophylactic microbiome therapies.Furthermore,the specific gut microbiota alterations may hold promise to predict the risk of hepatic encephalopathy in individuals undergoing TIPS for HBVrelated PH.Despite these promising findings,future studies are needed to address limitations,including a small sample size,a relatively short evaluation period for gut microbiota alterations,the absence of data on dynamic alterations in gut microbiota post-TIPS and their correlation with blood ammonia levels,and the lack of validation in animal models.In conclusion,Zhao et al's study has shed new light on the link of gut microbiota with post-TIPS hepatic encephalopathy,potentially through the intricate gut-liver axis,and has important clinical implications for improving the management of patients with HBV-related PH.
