Hepatic veno-occlusive disease induced by Gymura segetum: report of two cases

BACKGROUND: Hepatic veno-occlusive disease (VOD) or sinusoidal obstruction syndrome is associated with a high mortality because of its severity. Gymura segetum, a Chinese herbal medicine, is always used to cure injury and bleeding in rural areas in China. This study was undertaken to better understand VOD and its relations to the effect of Gymura segetum. METHODS: Between 2000 and 2002,two patients were admitted to our department because of VOD. Before admission, both of them had been injured and taken oral decoction of patent drug Gymura segetum. We analyzed the clinical manifestations, diagnosis and therapy of the two patients. RESULTS: Pyrrolizidine in Panax notginseng was proved to induce VOD. The diagnosis of VOD depended on hepatic biopsy. CONCLUSION: Gymura segetum can induce VOD. More attention should be paid to its unsuscepted side effects.

Reliable experimental model of hepatic veno-occlusive disease caused by monocrotaline

BACKGROUND:Hepatic veno-occlusive disease(HVOD)is a severe complication of chemotherapy before hematopoietic stem cell transplantation and dietary ingestion of pyrrolizidine alkaloids.Many experimental models were established to study its mechanisms or therapy,but few are ideal.This work aimed at evaluating a rat model of HVOD induced by monocrotaline to help advance research into this disease. METHODS:Thirty-two male rats were randomly classified into 5 groups,and PBS or monocrotaline was administered (100 mg/kg or 160 mg/kg).They were sacrificed on day 7(groups A,B and D)or day 10(groups C and E).Blood samples were collected to determine liver enzyme concentrations.The weight of the liver and body and the amount of ascites were measured.Histopathological changes of liver tissue on light microscopy were assessed by a modified Deleve scoring system.The positivity of proliferating cell nuclear antigen(PCNA)was estimated. RESULTS:The rats that were treated with 160 mg/kg monocrotaline presented with severe clinical symptoms (including two deaths)and the histopathological picture of HVOD.On the other hand,the rats that were fed with 100 mg/kg monocrotaline had milder and reversible manifestations.Comparison of the rats sacrificed on day 10 with those sacrificed on day 7 showed that the positivity of PCNA increased,especially that of hepatocytes.CONCLUSIONS:Monocrotaline induces acute,dose- dependent HVOD in rats.The model is potentially reversible with a low dose,but reliable and irreversible with a higher dose.The modified scoring system seems to be more accurate than the traditional one in reflecting the histopathology of HVOD.The enhancement of PCNA positivity may be associated with hepatic tissue undergoing recovery.

Hepatic veno-occlusive disease after hematopoietic stem cell transplantation: Prophylaxis and treatment controversies

Hepatic veno-occlusive disease(VOD), also known as sinusoidal obstruction syndrome, is a major complication of hematopoietic stem cell transplantation and it carries a high mortality. Prophylaxis for hepatic VOD is commonly given to transplant recipients from the start of conditioning through the early weeks of transplant. However, high quality evidence from randomized controlled trials is scarce with small sample sizes and the trials yielded conflicting results. Although various treatment options for hepatic VOD are available, most have not undergone stringent evaluation with randomized controlled trial and therefore it remains uncertain which treatment offers real benefit. It remains controversial whether VOD prophylaxis should be given, which prophylactic therapy should be given, who should receive prophylaxis, and what treatment should be offered once VOD is established.

Gynura root induces hepatic veno-occlusive disease:A case report and review of the literature

Gynura root has been used extensively in Chinese folk medicine and plays a role in promoting microcirculation and relieving pain.However,its hepatic toxicity should not be neglected.Recently,we admitted a 62-year old female who developed hepatic veno-occlusive disease(HVOD)after ingestion of Gynura root.Only a few articles on HVOD induced by Gynura root have been reported in the literature.It is suspected that pyrrolizidine alkaloids in Gynura root might be responsible for HVOD.In this paper,we report a case of HVOD and review the literature.

A case report of hepatic veno-occlusive disease after ingesting dainties

Hepatic veno-occlusive disease (HVOD) is rarely encountered and easily misjudged as Budd-Chiari syndrome. It is often related to stem cell transplantation in recent years. We report a case of HVOD that is related to ingestion of some palatable local dishes. The diagnosis was confirmed by liver biopsy pathology with specific observation of inflammatory changes and fibrosis of venules intima, dilated sinusoids and central veins. Chronic diarrhea is unique for this case as a result of ingesting harmful stuffs. This case demonstrated that supervision and instruction of food recipe and traditional medicine are crucial, and prompt diagnosis, supportive care and specific treatment are essential to decreasing the morbidity and mortality of HVOD.

One patient of hepatic veno-occlusive disease with an increased cancer antigen-125 expression caused by misuse of Sedum aizoon

目前我国的肝小静脉闭塞综合征主要由于服用中药土三七引起,其预后主要和服用土三七的量和疗程有关,缺乏其它客观的指标预测其预后。CA125与肝硬化密切相关,本例患者发现血清、胸水、腹水中CA125明显升高,短期内进展成肝硬化,并死于消化道大出血。因此我们推测CA125能预测肝小静脉闭塞综合征进展为肝硬化,从而可能作为临床上评估预后的指标。

Clinical characteristics and outcomes of patients with hepatic veno-occlusive disease induced by Gynura segetum: A retrospective study

Objective: Hepatic veno-occlusive disease(HVOD) has attracted increasing attention in recent years due to its relationship with ingestion of Gynura segetum. The mortality of severe HVOD remains high due to the lack of specific therapies. The aim of the study was to delineate the clinical characteristics and outcomes and explore the potential prognostic factors of HVOD.Methods: This was a single-center retrospective study. Eighty-nine HVOD patients were screened from the First Affiliated Hospital of Zhejiang University with an ingestion history of G. segetum before developing symptoms from January 2009 to May 2018. The enrolled patients were divided into the survivor and death groups according to the clinical follow-up that ended on September 1, 2019. The demographic variables and clinical data of the patients were recorded. A binary logistic regression analysis and receiver operating characteristic curve were conducted to identify the prognostic factors and assess the prognostic value for predicting death, and a survival analysis was performed to evaluate the clinical outcomes.Results: Sixty-four patients were eligible for further analysis. Most patients showed abdominal distension and were positive for migrating dullness in the abdomen(P = 0.740 and P = 0.732, respectively). The patients who died had higher levels of model for end-stage liver disease score, and higher prothrombin time than those who survived(both P < 0.001). All HVOD patients in both the survival and death groups showed ascites with abnormal imaging presentations of the liver parenchyma and hepatic blood vessels.Unexpectedly, we found that hydrothorax was detected in 21(65.63%) patients in the death group and 19(59.38%) patients in the survivor group during hospitalization, which was rarely mentioned in previous studies. Furthermore, international normalized ratio(INR) and creatinine are found to be potential independent prognostic factors for predicting death. Six severe patients achieved clinical improvements and survived after liver transplantation.Conclusion: HVOD can be induced by the ingestion of G. segetum, and INR combined with creatinine has prognostic value for predicting death. Liver transplantation may be an effective treatment option for severe HVOD patients.

Autoimmune hepatitis-primary biliary cholangitis overlap syndrome complicated by various autoimmune diseases:A case report

BACKGROUND Autoimmune hepatitis(AIH)and primary biliary cholangitis(PBC)are two common clinical autoimmune liver diseases,and some patients have both diseases;this feature is called AIH-PBC overlap syndrome.Autoimmune thyroid disease(AITD)is the most frequently overlapping extrahepatic autoimmune disease.Immunoglobulin(IgG)4-related disease is an autoimmune disease recognized in recent years,characterized by elevated serum IgG4 levels and infiltration of IgG4-positive plasma cells in tissues.CASE SUMMARY A 68-year-old female patient was admitted with a history of right upper quadrant pain,anorexia,and jaundice on physical examination.Laboratory examination revealed elevated liver enzymes,multiple positive autoantibodies associated with liver and thyroid disease,and imaging and biopsy suggestive of pancreatitis,hepatitis,and PBC.A diagnosis was made of a rare and complex overlap syndrome of AIH,PBC,AITD,and IgG4-related disease.Laboratory features improved on treatment with ursodeoxycholic acid,methylprednisolone,and azathioprine.CONCLUSION This case highlights the importance of screening patients with autoimmune diseases for related conditions.

Influence of nonalcoholic fatty liver disease on response to antiviral treatment in patients with chronic hepatitis B:A meta-analysis

BACKGROUND Although hepatitis B virus infection is the leading cause of chronic liver injury globally,nonalcoholic fatty liver disease(NAFLD)is gradually gaining attention as another major chronic liver disease.The number of patients having chronic hepatitis B(CHB)with concomitant hepatic steatosis has increased.AIM To analyze the effect of NAFLD on the response to antiviral treatment in patients with CHB.METHODS Relevant English studies were systematically searched across PubMed,EMBASE,Web of Science,and Cochrane Library until October 2023.Studies in which the treatment outcomes were compared between patients with CHB only and those with CHB and hepatic steatosis were included.RESULTS Of the 2502 retrieved studies,11 articles were finally included.Biochemical response until 48 wk(OR=0.87,95%CI:0.50–1.53,P=0.000)and 96 wk(OR=0.35,95%CI:0.24–0.53,P=0.24)and virological response until 96 wk(OR=0.80,95%CI:0.43–1.49,P=0.097)were lower in patients with hepatic steatosis than in patients with CHB alone.CONCLUSION Hepatic steatosis lowers the biochemical response to antiviral treatment in patients with CHB.

Challenges and dilemmas in pediatric hepatic Wilson’s disease

Wilson disease is an autosomal recessive disorder affecting the ATP7B gene located on chromosome 13q.This leads to copper deposition in various organs,most importantly in the liver and brain.The genetic mutations are vast,well reported in the West but poorly documented in developing countries.Hence the diagnosis is made with a constellation of clinico-laboratory parameters which have significant overlap with other liver diseases and often pose a significant dilemma for clinicians.Diagnostic scoring systems are not fool-proof.The availability and affordability of chelators in developing countries impact the drug compliance of patients.While D-penicillamine is a potent drug,its side effects lead to drug discontinuation.Trientine is cost-prohibitive in developing countries.There is no single test to assess the adequacy of chelation.Exchangeable urinary copper is an essential upcoming diagnostic and prognostic tool.In the presence of cirrhosis,hypersplenism clouds the assessment of myelosuppression of drugs.Similarly,it may be difficult to distinguish disease tubulopathy from druginduced glomerulonephritis.Neurological worsening due to chelators may appear similar to disease progression.Presentation as fulminant hepatic failure requires rapid workup.There is a limited window of opportunity to salvage these patients with the help of plasmapheresis and other liver-assisted devices.This review addresses the challenges and clinical dilemmas faced at beside in developing countries.

Portal hypertension in patients with nonalcoholic fatty liver disease:Current knowledge and challenges

Portal hypertension(PH)has traditionally been observed as a consequence of significant fibrosis and cirrhosis in advanced non-alcoholic fatty liver disease(NAFLD).However,recent studies have provided evidence that PH may develop in earlier stages of NAFLD,suggesting that there are additional pathogenetic mechanisms at work in addition to liver fibrosis.The early development of PH in NAFLD is associated with hepatocellular lipid accumulation and ballooning,leading to the compression of liver sinusoids.External compression and intraluminal obstacles cause mechanical forces such as strain,shear stress and elevated hydrostatic pressure that in turn activate mechanotransduction pathways,resulting in endothelial dysfunction and the development of fibrosis.The spatial distribution of histological and functional changes in the periportal and perisinusoidal areas of the liver lobule are considered responsible for the pre-sinusoidal component of PH in patients with NAFLD.Thus,current diagnostic methods such as hepatic venous pressure gradient(HVPG)measurement tend to underestimate portal pressure(PP)in NAFLD patients,who might decompensate below the HVPG threshold of 10 mmHg,which is traditionally considered the most relevant indicator of clinically significant portal hypertension(CSPH).This creates further challenges in finding a reliable diagnostic method to stratify the prognostic risk in this population of patients.In theory,the measurement of the portal pressure gradient guided by endoscopic ultrasound might overcome the limitations of HVPG measurement by avoiding the influence of the pre-sinusoidal component,but more investigations are needed to test its clinical utility for this indication.Liver and spleen stiffness measurement in combination with platelet count is currently the best-validated non-invasive approach for diagnosing CSPH and varices needing treatment.Lifestyle change remains the cornerstone of the treatment of PH in NAFLD,together with correcting the components of metabolic syndrome,using nonselective beta blockers,whereas emerging candidate drugs require more robust confirmation from clinical trials.

Metabolic dysfunction-associated fatty liver disease and low muscle strength: A comment

The diagnosis of non-alcoholic fatty liver disease(NAFLD)and metabolic dysfunction-associated fatty liver disease only on the basis of laboratory parameter score such as Hepatic Steatosis Index which includes liver enzymes,gender,basal metabolic index,and presence of diabetic mellitus is not sufficient to exclude other causes of deranged liver enzymes especially medications and autoimmune related liver diseases.As the guideline suggests ultrasound is the preferred first-line diagnostic procedure for imaging of NAFLD,as it provides additional diagnostic information and the combination of biomarkers/scores and transient elastography might confer additional diagnostic accuracy and evident from previous similar studies too.

Role of fecal microbiota transplant in management of hepatic encephalopathy: Current trends and future directions

Fecal microbiota transplantation(FMT)offers a potential treatment avenue for hepatic encephalopathy(HE)by leveraging beneficial bacterial displacement to restore a balanced gut microbiome.The prevalence of HE varies with liver disease severity and comorbidities.HE pathogenesis involves ammonia toxicity,gut-brain communication disruption,and inflammation.FMT aims to restore gut microbiota balance,addressing these factors.FMT's efficacy has been explored in various conditions,including HE.Studies suggest that FMT can modulate gut microbiota,reduce ammonia levels,and alleviate inflammation.FMT has shown promise in alcohol-associated,hepatitis B and C-associated,and non-alcoholic fatty liver disease.Benefits include improved liver function,cognitive function,and the slowing of disease progression.However,larger,controlled studies are needed to validate its effectiveness in these contexts.Studies have shown cognitive improvements through FMT,with potential benefits in cirrhotic patients.Notably,trials have demonstrated reduced serious adverse events and cognitive enhancements in FMT arms compared to the standard of care.Although evidence is promising,challenges remain:Limited patient numbers,varied dosages,administration routes,and donor profiles.Further large-scale,controlled trials are essential to establish standardized guidelines and ensure FMT's clinical applications and efficacy.While FMT holds potential for HE management,ongoing research is needed to address these challenges,optimize protocols,and expand its availability as a therapeutic option for diverse hepatic conditions.

Liver disease in patients with transfusion-dependentβ-thalassemia:The emerging role of metabolism dysfunction-associated steatotic liver disease

In this Editorial,we highlight the possible role that metabolism dysfunction-associated steatotic liver disease(MASLD)may play in the future,regarding liver disease in patients with transfusion-dependent β-thalassemia(TDBT).MASLD is characterized by excessive accumulation of fat in the liver(hepatic steatosis),in the presence of cardiometabolic factors.There is a strong correlation between the occurrence of MASLD and insulin resistance,while its increased prevalence parallels the global epidemic of diabetes mellitus(DM)and obesity.Patients with TDBT need regular transfusions for life to ensure their survival.Through these transfusions,a large amount of iron is accumulated,which causes saturation of transferrin and leads to the circulation of free iron molecules,which cause damage to vital organs(primarily the liver and myocardium).Over the past,the main mechanisms for the development of liver disease in these patients have been the toxic effect of iron on the liver and chronic hepatitis C,for which modern and effective treatments have been found,resulting in successful treatment.Additional advances in the treatment and monitoring of these patients have led to a reduction in deaths,and an increase in their life expectancy.This increased survival makes them vulnerable to the onset of diseases,which until recently were mainly related to the non-thalassemic general population,such as obesity and DM.There is insufficient data in the literature regarding the prevalence of MASLD in this population or on the risk factors for its occurrence.However,it was recently shown by a study of 45 heavily transfused patients with beta-thalassemia(Padeniya et al,BJH),that the presence of steatosis is a factor influencing the value of liver elastography and thus liver fibrosis.These findings suggest that future research in the field of liver disease in patients with TDBT should be focused on the occurrence,the risk factors,and the effect of MASLD on these patients.

Outcomes of ABO-incompatible liver transplantation in end-stage liver disease patients co-infected with hepatitis B and human immunodeficiency virus

BACKGROUND Human immunodeficiency virus(HIV)-positive patients coinfected with hepatitis B virus(HBV)are eligible for liver transplantation(LT)in Africa and Southeast Asia,particularly China.However,the outcome of HIV-HBV coinfected patients referred for ABO-incompatible LT(ABOi-LT)is unknown.AIM To clarify the outcome of ABOi-LT for HIV-HBV coinfected patients with endstage liver disease(ESLD).METHODS We report on two Chinese HIV-HBV coinfected patients with ESLD who underwent A to O brain-dead donor LT and reviewed the literature on HIV-HBV coinfected patients treated with ABO-compatible LT.The pretransplantation HIV viral load was undetectable,with no active opportunistic infections.Induction therapy consisted of two sessions of plasmapheresis and a single dose of rituximab in two split doses,followed by an intraoperative regimen of intravenous immunoglobulin,methylprednisolone,and basiliximab.Post-transplant maintenance immunosuppressive agents consisted of tacrolimus and mycophenolate mofetil,and prednisone.RESULTS At the intermediate-term follow-up,patients showed undetectable HIV viral load,CD4(+)T cell counts greater than 150 cells/μL,no HBV recurrence,and stable liver function.A liver allograft biopsy showed no evidence of acute cellular rejection.Both patients survived at 36-42 mo of follow-up.CONCLUSION This is the first report of ABOi-LT in HIV-HBV recipients with good intermediate-term outcomes,suggesting that ABOi-LT may be feasible and safe for HIV-HBV coinfected patients with ESLD.

Prevalence and outcome of sarcopenia in non-alcoholic fatty liver disease

BACKGROUND Nonalcoholic fatty liver disease(NAFLD)includes a spectrum of conditions,progressing from mild steatosis to advanced fibrosis.Sarcopenia,characterized by decreased muscle strength and mass,shares common pathophysiological traits with NAFLD.An association exists between sarcopenia and increased NAFLD prevalence.However,data on the prevalence of sarcopenia in NAFLD and its impact on the outcomes of NAFLD remain inconsistent.AIM To analyze the prevalence and outcomes of sarcopenia in patients with NAFLD.METHODS We conducted a comprehensive search for relevant studies in MEDLINE,Embase,and Scopus from their inception to June 2023.We included studies that focused on patients with NAFLD,reported the prevalence of sarcopenia as the primary outcome,and examined secondary outcomes,such as liver fibrosis and other adverse events.We also used the Newcastle-Ottawa scale for quality assessment.RESULTS Of the 29 studies included,the prevalence of sarcopenia in NAFLD varied widely(1.6%to 63.0%),with 20 studies reporting a prevalence of more than 10.0%.Substantial heterogeneity was noted in the measurement modalities for sarcopenia.Sarcopenia was associated with a higher risk of advanced fibrosis(odd ratio:1.97,95%confidence interval:1.44-2.70).Increased odds were consistently observed in fibrosis assessment through biopsy,NAFLD fibrosis score/body mass index,aspartate aminotransferase to alanine aminotransferase ratio,diabetes(BARD)score,and transient elastography,whereas the fibrosis-4 score showed no such association.Sarcopenia in NAFLD was associated with a higher risk of steatohepatitis,insulin resistance,cardiovascular risks,and mortality.CONCLUSION This systematic review highlights the critical need for standardized diagnostic criteria and measurement methods for sarcopenia in NAFLD patients.The variability in study designs and assessment methods for sarcopenia and liver fibrosis may account for the inconsistent findings.This review demonstrates the multidimensional impact of sarcopenia on NAFLD,indicating its importance beyond liver-related events to include cardiovascular risks,mortality,and metabolic complications.

Hepatitis B virus infection in patients with Wilson disease:A large retrospective study

BACKGROUND Wilson disease(WD)is the most common genetic metabolic liver disease.Some studies have shown that comorbidities may have important effects on WD.Data on hepatitis B virus(HBV)infection in patients with WD are limited.AIM To investigate the prevalence and clinical impact of HBV infection in patients with WD.METHODS The clinical data of patients with WD were analyzed retrospectively,and the data of patients with concurrent WD and HBV infection were compared with those of patients with isolated WD.RESULTS Among a total of 915 WD patients recruited,the total prevalence of current and previous HBV infection was 2.1%[95%confidence interval(CI):1.2%-3.0%]and 9.2%(95%CI:7.3%-11.1%),respectively.The main finding of this study was the identification of 19 patients with concurrent WD and chronic hepatitis B(CHB)infection.The diagnosis of WD was missed in all but two patients with CHB infection.The mean delay in the diagnosis of WD in patients with concurrent WD and CHB infection was 32.5 mo,which was significantly longer than that in patients with isolated WD(10.5 mo).The rates of severe liver disease and mortality in patients with concurrent WD and CHB infection were significantly higher than those in patients with isolated WD(63.1%vs 19.3%,P=0.000 and 36.8%vs 4.1%,P<0.001,respectively).Binary logistic regression analysis revealed a significantly higher risk of severe liver disease at the diagnosis of WD in patients with current HBV infection[odds ratio(OR)=7.748;95%CI:2.890-20.774;P=0.000)]or previous HBV infection(OR=5.525;95%CI:3.159-8.739;P=0.000)than in patients with isolated WD.CONCLUSION The total prevalence of current HBV infection in patients with WD was 2.1%.The diagnosis of WD in CHB patients is usually missed.HBV infection is an independent risk factor for severe liver disease in WD patients.The diagnosis of WD should be ruled out in some patients with CHB infection.

Hepatitis A virus-associated acute acalculous cholecystitis in an adult-onset Still’s disease patient:A case report and review of the literature

BACKGROUND Acute acalculous cholecystitis(AAC)is inflammation of the gallbladder without evidence of calculi.Although rarely reported,its etiologies include hepatitis virus infection(e.g.,hepatitis A virus,HAV)and adult-onset Still’s disease(AOSD).There are no reports of HAV-associated AAC in an AOSD patient.CASE SUMMARY Here we report a rare case of HAV infection-associated AAC in a 39-year-old woman who had a history of AOSD.The patient presented with an acute abdomen and hypotension.Elevated hepatobiliary enzymes and a thickened and distended gallbladder without gallstones on ultrasonography suggested AAC,but there were no signs of anemia nor thrombocytopenia.Serological screening revealed anti-HAV IgM antibodies.Steroid treatment did not alleviate her symptoms,and she was referred for laparoscopic cholecystectomy.The resected gallbladder was hydropic without perforation,and her clinical signs gradually improved after surgery.CONCLUSION AAC can be caused by HAV in AOSD patients.It is crucial to search for the underlying etiology for AAC,especially uncommon viral causes.

Better performance of PIVKA-II for detecting hepatocellular carcinoma in patients with chronic liver disease with normal total bilirubin

BACKGROUND Serum protein induced by vitamin K absence or antagonist-Ⅱ(PIVKA-Ⅱ) is a promising biomarker for hepatocellular carcinoma(HCC) surveillance.AIM To identify the contributing factors related to the abnormal elevation of PIVKA-Ⅱ level and assess their potential influence on the performance of PIVKA-Ⅱ in detecting HCC.METHODS This study retrospectively enrolled in 784 chronic liver disease(CLD) patients and 267 HCC patients in Mengchao Hepatobiliary Hospital of Fujian Medical University from April 2016 to December 2019. Logistic regression and the area under the receiver operating characteristic curve(AUC) were used to evaluate the influencing factors and diagnostic performance of PIVKA-Ⅱ for HCC, respectively.RESULTS Elevated PIVKA-Ⅱ levels were independently positively associated with alcohol-related liver disease, serum alkaline phosphatase(ALP), and total bilirubin(TBIL) for CLD patients and aspartate aminotransferase(AST) and tumor size for HCC patients(all P < 0.05). Serum PIVKA-Ⅱ were significantly lower in patients with viral etiology, ALP ≤ 1 × upper limit of normal(ULN), TBIL ≤ 1 × ULN, and AST ≤ 1 × ULN than in those with nonviral disease and abnormal ALP, TBIL, or AST(all P < 0.05), but the differences disappeared in patients with early-stage HCC. For patients with TBIL ≤ 1 × ULN, the AUC of PIVKA-Ⅱ was significantly higher compared to that in patients with TBIL > 1 × ULN(0.817 vs 0.669, P = 0.015), while the difference between ALP ≤ 1 × ULN and ALP > 1 × ULN was not statistically significant(0.783 vs 0.729, P = 0.398). These trends were then more prominently perceived in subgroups of patients with viral etiology and HBV alone.CONCLUSION Serum PIVKA-Ⅱ has better performance in detecting HCC at an early stage for CLD patients with normal serum TBIL.
