In Chad, more particularly, no data are available despite the burden of liver diseases considered as the first cause of hospitalizations in the country. Methods: We conducted a retrospective analysis of 268 patients with liver cirrhosis attending care at the University Reference Hospital between 2007 and 2016. Results: This series of liver cirrhoses was characterized by a weak mal predominance (M:F = 1.7). The age of onset occurs significantly earlier in women than in men (40.6 ± 12.0 vs. 44.4 ± 13.4, p = 0.0171). The principal risk factor was persistent infection with hepatitis B virus (49% of cases) followed distantly by infection with hepatitis C virus (13%) and excessive alcohol consumption (10%). Men were more frequently carrying HBV surface antigen than women (65.6% vs 35.9% p = 0.0019). HBV-associated liver cirrhosis was overall more severe than diseases from other causes. A large proportion of cirrhosis (30%), observed primarily in women (48.1% vs 24.1%, p = 0.0036), was considered are cryptogenic. Conclusions: The etiological spectrum of liver cirrhosis remains to be properly defined in Chad. This lack of knowledge prevents the implementation of an efficient policy of prevention. A significant effort should be secured to characterize hitherto neglected infectious, lifestyle or genetic risk factors responsible of this form of terminal disease and improve subsequently liver health of local populations.展开更多

文摘We read with interest the article by Xing Wang,which was published in the recent issue of the World Journal of Hepatology 2023;15:1294-1306.This article focuses particularly on the prevalence and trends in the etiology of liver cirrhosis(LC),prognosis for patients suffering from cirrhosis-related complications and hepatocellular carcinoma(HCC),and management strategies.The etiology of cirrhosis varies according to geographical,economic,and population factors.Viral hepatitis is the dominant cause in China.Vaccination and effective treatment have reduced the number of people with viral hepatitis,but the overall number is still large.Patients with viral hepatitis who progress over time to LC and HCC remain an important population to manage.The increased incidence of metabolic syndrome and alcohol consumption is likely to lead to a potential exponential increase in metabolic dysfunction-associated steatotic liver disease(MASLD)-associated LC and alcoholic liver disease in the future.Investigating the evolution of the etiology of LC is important for guiding the direction of future research and policy development.These changing trends indicate a need for greater emphasis on tackling obesity and diabetes,and implementing more effective measures to regulate alcohol consumption in order to reduce the occurrence of MASLD.In an effort to help cope with these changing trends,the authors further proposed countermeasures for healthcare authorities doctors,and patients.
文摘BACKGROUND For compensated advanced chronic liver disease(cACLD)patients,the first decompensation represents a dramatically worsening prognostic event.Based on the first decompensation event(DE),the transition to decompensated advanced chronic liver disease(dACLD)can occur through two modalities referred to as acute decompensation(AD)and non-AD(NAD),respectively.Clinically Significant Portal Hypertension(CSPH)is considered the strongest predictor of decompensation in these patients.However,due to its invasiveness and costs,CSPH is almost never evaluated in clinical practice.Therefore,recognizing noninvasively predicting tools still have more appeal across healthcare systems.The red cell distribution width to platelet ratio(RPR)has been reported to be an indicator of hepatic fibrosis in Metabolic Dysfunction-Associated Steatotic Liver Disease(MASLD).However,its predictive role for the decompensation has never been explored.AIM In this observational study,we investigated the clinical usage of RPR in predicting DEs in MASLD-related cACLD patients.METHODS Fourty controls and 150 MASLD-cACLD patients were consecutively enrolled and followed up(FUP)semiannually for 3 years.At baseline,biochemical,clinical,and Liver Stiffness Measurement(LSM),Child-Pugh(CP),Model for End-Stage Liver Disease(MELD),aspartate aminotransferase/platelet count ratio index(APRI),Fibrosis-4(FIB-4),Albumin-Bilirubin(ALBI),ALBI-FIB-4,and RPR were collected.During FUP,DEs(timing and modaities)were recorded.CSPH was assessed at the baseline and on DE occurrence according to the available Clinical Practice Guidelines.RESULTS Of 150 MASLD-related cACLD patients,43(28.6%)progressed to dACLD at a median time of 28.9 months(29 NAD and 14 AD).Baseline RPR values were significantly higher in cACLD in comparison to controls,as well as MELD,CP,APRI,FIB-4,ALBI,ALBI-FIB-4,and LSM in dACLD-progressing compared to cACLD individuals[all P<0.0001,except for FIB-4(P:0.007)and ALBI(P:0.011)].Receiving operator curve analysis revealed RPR>0.472 and>0.894 as the best cut-offs in the prediction respectively of 3-year first DE,as well as its superiority compared to the other non-invasive tools examined.RPR(P:0.02)and the presence of baseline-CSPH(P:0.04)were significantly and independently associated with the DE.Patients presenting baseline-CSPH and RPR>0.472 showed higher risk of decompensation(P:0.0023).CONCLUSION Altogether these findings suggest the RPR as a valid and potentially applicable non-invasive tool in the prediction of timing and modalities of decompensation in MASLD-related cACLD patients.
文摘To the Editor: Fatty liver diseases, including nonalcoholic fatty liver disease and alcohol related fatty liver disease, have become a major public health concern [ 1, 2 ]. Fatty liver diseases have been shown to progress through various stages, from steatosis or necrosis with inflammation and hepatocyte damage to the development of fibrosis and eventual cirrhosis with an increased risk of carcinoma [ 2, 3 ].
文摘Hepatocrinology explores the intricate relationship between liver function and the endocrine system.Chronic liver diseases such as liver cirrhosis can cause endocrine disorders due to toxin accumulation and protein synthesis disruption.Despite its importance,assessing endocrine issues in cirrhotic patients is frequently neglected.This article provides a comprehensive review of the epidemiology,pathophysiology,diagnosis,and treatment of endocrine disturbances in liver cirrhosis.The review was conducted using the PubMed/Medline,EMBASE,and Scielo databases,encompassing 172 articles.Liver cirrhosis is associated with endocrine disturbances,including diabetes,hypoglycemia,sarcopenia,thyroid dysfunction,hypogonadotropic hypogonadism,bone disease,adrenal insufficiency,growth hormone dysfunction,and secondary hyperaldosteronism.The optimal tools for diagnosing diabetes and detecting hypoglycemia are the oral glucose tolerance test and continuous glucose monitoring system,respectively.Sarcopenia can be assessed through imaging and functional tests,while other endocrine disorders are evaluated using hormonal assays and imaging studies.Treatment options include metformin,glucagon-like peptide-1 analogs,sodium-glucose co-transporter-2 inhibitors,and insulin,which are effective and safe for diabetes control.Established standards are followed for managing hypoglycemia,and hormone replacement therapy is often necessary for other endocrine dysfunctions.Liver transplantation can address some of these problems.

文摘BACKGROUND Acute decompensation(AD)of cirrhosis is associated with high short-term mortality,mainly due to the development of acute-on-chronic liver failure(ACLF).Thus,there is a need for biomarkers for early and accurate identification of AD patients with high risk of development of ACLF and mortality.Soluble triggering receptor expressed on myeloid cells-1(sTREM-1)is released from activated innate immune cells and correlated with various inflammatory processes.AIM To explore the prognostic value of sTREM-1 in patients with AD of cirrhosis.METHODS A multicenter prospective cohort of 442 patients with cirrhosis hospitalized for AD was divided into a study cohort(n=309)and validation cohort(n=133).Demographic and clinical data were collected,and serum sTREM-1 was measured at admission.All enrolled patients were followed-up for at least 1 year.RESULTS In patients with AD and cirrhosis,serum sTREM-1 was an independent prognosis predictor for 1-year survival and correlated with liver,coagulation,cerebral and kidney failure.A new prognostic model of AD(P-AD)incorporating sTREM-1,blood urea nitrogen(BUN),total bilirubin(TBil),international normalized ratio(INR)and hepatic encephalopathy grades was established and performed better than the model for end-stage liver disease(MELD),MELD-sodium(MELD-Na),chronic liver failure-consortium(CLIF-C)ACLF and CLIF-C AD scores.Additionally,sTREM-1 was increased in ACLF and predicted the development of ACLF during first 28-d follow-up.The ACLF risk score incorporating serum sTREM-1,BUN,INR,TBil and aspartate aminotransferase levels was established and significantly superior to MELD,MELD-Na,CLIF-C ACLF,CLIF-C AD and P-AD in predicting risk of ACLF development.CONCLUSION Serum sTREM-1 is a promising prognostic biomarker for ACLF development and mortality in patients with AD of cirrhosis.
文摘This editorial describes the contemporary concepts of prevention and management of gastroesophageal variceal bleeding in liver cirrhosis(LC)patients according to the current guidelines.Gastroesophageal variceal bleeding is the most dangerous complication of portal hypertension in LC patients.Risk stratification and determination of an individual approach to the choice of therapeutic measures aimed at their prevention and management has emerged as one of the top concerns in modern hepatology.According to the current guidelines,in the absence of clinically significant portal hypertension,etiological and nonetiological therapies of LC is advisable for the primary preventing gastroesophageal variceal bleeding,whereas its presence serves as an indication for the administration of non-selectiveβ-blockers,among which carvedilol is the drug of choice.Non-selectiveβ-blockers,as well as endoscopic variceal ligation and transjugular intrahepatic portosystemic shunt can be used to prevent recurrence of gastroesophageal variceal bleeding.Pharmacotherapy with vasoactive drugs(terlipressin,somatostatin,octreotide),endoscopic variceal ligation,endovascular techniques and transjugular intrahepatic portosystemic shunt are recommended for the treatment of acute gastroesophageal variceal bleeding.Objective and accurate risk stratification of gastroesophageal variceal bleeding will allow developing individual strategies for their prevention and management,avoiding the first and further decompensation in LC,which will improve the prognosis and survival of patients suffering from it.

文摘BACKGROUND During cirrhosis,the liver is impaired and unable to synthesize and clear thrombopoietin properly.At the same time,the spleen assumes the function of hemofiltration and storage due to liver dysfunction,resulting in hypersplenism and excessive removal of platelets in the spleen,further reducing platelet count.When liver function is decompensated in cirrhotic patients,the decrease of thrombopoietin(TPO)synthesis is the main reason for the decrease of new platelet production.This change of TPO leads to thrombocytopenia and bleeding tendency in cirrhotic patients with hypersplenism.AIM To investigate the clinical efficacy of recombinant human TPO(rhTPO)in the treatment of perioperative thrombocytopenia during liver transplantation in cirrhotic mice with hypersplenism.METHODS C57BL/6J mice and TPO receptor-deficient mice were used to establish models of cirrhosis with hypersplenism.Subsequently,these mice underwent orthotopic liver transplantation(OLT).The mice in the experimental group were given rhTPO treatment for 3 consecutive days before surgery and 5 consecutive days after surgery,while the mice in the control group received the same dose of saline at the same frequency.Differences in liver function and platelet counts were determined between the experimental and control groups.Enzyme-linked immunosorbent assay was used to assess the expression of TPO and TPO receptor(c-Mpl)in the blood.RESULTS Preoperative administration of rhTPO significantly improved peri-OLT thrombocytopenia in mice with cirrhosis and hypersplenism.Blocking the expression of TPO receptors exacerbated peri-OLT thrombocytopenia.The concentration of TPO decreased while the concentration of c-Mpl increased in compensation in the mouse model of cirrhosis with hypersplenism.TPO pre-treatment significantly increased the postoperative TPO concentration in mice,which in turn led to a decrease in the c-Mpl concentration.TPO pre-treatment also significantly enhanced the Janus kinase(Jak)/signal transducers and activators of transcription pathway protein expressions in bone marrow stem cells of the C57BL/6J mice.Moreover,the administration of TPO,both before and after surgery,regulated the levels of biochemical indicators,such as alanine aminotransferase,alkaline phosphatase,and aspartate aminotransferase in the C57BL/6J mice.CONCLUSION Pre-treatment with TPO not only exhibited therapeutic effects on perioperative thrombocytopenia in the mice with cirrhosis and hypersplenism,who underwent liver transplantation but also significantly enhanced the perioperative liver function.

文摘BACKGROUND Alterations in plasma and intestinal metabolites contribute to the pathogenesis and progression of alcohol-related liver cirrhosis(ALC).AIM To explore the common and different metabolites in the plasma and feces of patients with ALC and evaluate their clinical implications.METHODS According to the inclusion and exclusion criteria,27 patients with ALC and 24 healthy controls(HCs)were selected,and plasma and feces samples were collected.Liver function,blood routine,and other indicators were detected with automatic biochemical and blood routine analyzers.Liquid chromatography-mass spectrometry was used to detect the plasma and feces metabolites of the two groups and the metabolomics of plasma and feces.Also,the correlation between metabolites and clinical features was analyzed.RESULTS More than 300 common metabolites were identified in the plasma and feces of patients with ALC.Pathway analysis showed that these metabolites are enriched in bile acid and amino acid metabolic pathways.Compared to HCs,patients with ALC had a higher level of glycocholic acid(GCA)and taurocholic acid(TCA)in plasma and a lower level of deoxycholic acid(DCA)in the feces,while L-threonine,L-phenylalanine,and L-tyrosine increased simultaneously in plasma and feces.GCA,TCA,L-methionine,L-phenylalanine,and L-tyrosine in plasma were positively correlated with total bilirubin(TBil),prothrombin time(PT),and maddrey discriminant function score(MDF)and negatively correlated with cholinesterase(CHE)and albumin(ALB).The DCA in feces was negatively correlated with TBil,MDF,and PT and positively correlated with CHE and ALB.Moreover,we established a P/S BA ratio of plasma primary bile acid(GCA and TCA)to fecal secondary bile acid(DCA),which was relevant to TBil,PT,and MDF score.CONCLUSION The enrichment of GCA,TCA,L-phenylalanine,L-tyrosine,and L-methionine in the plasma of patients with ALC and the reduction of DCA in feces were related to the severity of ALC.These metabolites may be used as indicators to evaluate the progression of alcohol-related liver cirrhosis.
文摘Background: In comparison to other forms of chronic liver diseases, cirrhosis is generally poorly studied in sub Saharan Africa. In Chad, more particularly, no data are available despite the burden of liver diseases considered as the first cause of hospitalizations in the country. Methods: We conducted a retrospective analysis of 268 patients with liver cirrhosis attending care at the University Reference Hospital between 2007 and 2016. Results: This series of liver cirrhoses was characterized by a weak mal predominance (M:F = 1.7). The age of onset occurs significantly earlier in women than in men (40.6 ± 12.0 vs. 44.4 ± 13.4, p = 0.0171). The principal risk factor was persistent infection with hepatitis B virus (49% of cases) followed distantly by infection with hepatitis C virus (13%) and excessive alcohol consumption (10%). Men were more frequently carrying HBV surface antigen than women (65.6% vs 35.9% p = 0.0019). HBV-associated liver cirrhosis was overall more severe than diseases from other causes. A large proportion of cirrhosis (30%), observed primarily in women (48.1% vs 24.1%, p = 0.0036), was considered are cryptogenic. Conclusions: The etiological spectrum of liver cirrhosis remains to be properly defined in Chad. This lack of knowledge prevents the implementation of an efficient policy of prevention. A significant effort should be secured to characterize hitherto neglected infectious, lifestyle or genetic risk factors responsible of this form of terminal disease and improve subsequently liver health of local populations.

文摘Objective:Liver cirrhosis is a disease that seriously damages human health.Traditional Chinese Medicine(TCM)formulae have a good therapeutic effect on cirrhosis,and the herb pair is the smallest unit in formula compatibility,which is important for improving the therapeutic effect.Therefore,identifying core herb pairs among TCM formulae is key.Methods:We mined the data of TCM formulae for the treatment of cirrhosis in the China National Intellectual Property Administration for the first time and analyzed their herb characteristics and association rules.We screened 405 patented TCM formulae,including 953 herbs.Based on frequency statistics and association rules,we determined“Astragali Radix-Salviae Miltiorrhizae Radix Et Rhizoma”as the core herb pair.Results:Six active compounds,Isorhamnetin,Formononetin,Calycosin,Cryptotanshinone,Dihydrotanshinone I,and Tanshinone II A,were screened out based on previous studies and network pharmacology.We found that SRC,TP53,HSP90AA1,MAPK3,MAPK1,and STAT3 played pivotal roles in treating cirrhosis.Interestingly,molecular docking indicated that MAPK3 might be a potential pharmacological target for cirrhosis.Conclusion:We preliminarily predicted and verified the pharmacological and molecular mechanism of“Astragali Radix-Salviae Miltiorrhizae Radix Et Rhizoma”in treating cirrhosis.This can expand the scope of TCM in the treatment of cirrhosis,guide people to use clinical formulae,and provide valuable insights for further drug discovery studies.
文摘Decreased muscle mass and function,also known as sarcopenia,is common in patients with cirrhosis and is associated with a poor prognosis.Although the pathogenesis of this disorder has not been fully elucidated,a disordered gutmuscle axis probably plays an important role.Decreased barrier function of the gut and liver,gut dysbiosis,and small intestinal bacterial overgrowth(SIBO)can lead to increased blood levels of ammonia,lipopolysaccharides,pro-inflammatory mediators,and myostatin.These factors have complex negative effects on muscle mass and function.Drug interventions that target the gut microbiota(long-term use of rifaximin,lactulose,lactitol,or probiotics)positively affect most links of the compromised gut-muscle axis in patients with cirrhosis by decreasing the levels of hyperammonemia,bacterial translocation,and systemic inflammation and correcting gut dysbiosis and SIBO.However,although these drugs are promising,they have not yet been investigated in randomized controlled trials specifically for the treatment and prevention of sarcopenia in patients with cirrhosis.No data exist on the effects of fecal transplantation on most links of gut-muscle axis in cirrhosis;however,the results of animal experimental studies are promising.
文摘Transjugular intrahepatic portosystemic shunt(TIPS)is a medical procedure that has been used to manage variceal bleeding and ascites in patients with cirrhosis.It can prevent further decompensation and improve the survival of high-risk decompensated patients.Recent research indicates that TIPS could increase the possibility of recompensation of decompensated cirrhosis when it is combined with adequate suppression of the causative factor of liver disease.However,the results of the studies have been based on retrospective analysis,and further validation is required by conducting randomized controlled studies.In this context,we highlight the limitations of the current studies and emphasize the issues that must be addressed before TIPS can be recommended as a potential recompensating tool.
文摘Hepatitis C virus(HCV)remains a significant public health problem as it can cause acute and chronic hepatitis.Chronic HCV infection is a major cause of liver fibrosis,and evaluation of liver fibrosis is essential because the prognosis of patients with chronic HCV infection is closely related to the stage of fibrosis.Liver fibrosis is traditionally evaluated based on pathological analysis of biopsy specimens,which is considered the gold standard.Nevertheless,liver biopsy is invasive and susceptible to sampling error and inter-and intraobserver variation in pathological interpretation;it is also costly.Therefore,noninvasive diagnostic investigations have been developed,including the use of fibrotic markers,scoring systems based on routine blood tests,and transient elastography with magnetic resonance imaging or ultrasonography.Recently,metabolomics,an emerging technology,has been used to detect the fibrosis stage.In this editorial,I comment on the article titled“Metabolomics in chronic hepatitis C:Decoding fibrosis grading and underlying pathways”by Ferrasi et al published in the recent issue of the World Journal of Hepatology.I discuss previous studies on the use of metabolome analysis for the diagnosis of HCV-related liver fibrosis and the potential development of biopsy-free diagnostic techniques.

文摘BACKGROUND Chylous ascites is caused by disruption of the lymphatic system,which is characterized by the accumulation of a turbid fluid containing high levels of triglycerides within the abdominal cavity.The two most common causes are cirrhosis and tuberculosis,and colon signer ring cell carcinoma(SRCC)due to the use of immunosuppressants is extremely rare in cirrhotic patients after liver transplantation,making it prone to misdiagnosis and missed diagnosis.CASE SUMMARY A 52-year-old man who underwent liver transplantation and was administered with immunosuppressants for 8 months was admitted with a 3-month history of progressive abdominal distention.Initially,based on lymphoscintigraphy and lymphangiography,lymphatic obstruction was considered,and cystellar chyli decompression with band lysis and external membrane stripping of the lymphatic duct was performed.However,his abdominal distention was persistent without resolution.Abdominal paracentesis revealed allogenic cells in the ascites,and immunohistochemistry analysis revealed adenocarcinoma cells with phenotypic features suggestive of a gastrointestinal origin.Gastrointestinal endoscopy was performed,and biopsy showed atypical signet ring cells in the ileocecal valve.The patient eventually died after a three-month follow-up due to progression of the tumor.CONCLUSION Colon SRCC,caused by immunosuppressants,is an unusual but un-neglected cause of chylous ascites.
文摘Liver cirrhosis is commonly associated with nutritional alterations,reported in 20% of patients with compensated disease and over 60% of patients with decompensated cirrhosis.Nutritional disturbances are associated with a worse prognosis and increased risk of complication.Serum levels of branched-chain amino acids(BCAAs)are decreased in patients with liver cirrhosis.The imbalance of amino acids levels has been suggested to be associated with the development of complications,such as hepatic encephalopathy and sarcopenia,and to affect the clinical presentation and prognosis of these patients.Several studies investigated the efficacy of BCAAs supplementation as a therapeutic option in liver cirrhosis,but uncertainties remain about the real efficacy,the best route of administration,and dosage.
文摘BACKGROUND Corrected QT(QTc)interval is prolonged in patients with liver cirrhosis and has been proposed to correlate with the severity of the disease.However,the effects of sex,age,severity,and etiology of cirrhosis on QTc have not been elucidated.At the same time,the role of treatment,acute illness,and liver transplantation(Tx)remains largely unknown.AIM To determine the mean QTc in patients with cirrhosis,assess whether QTc is prolonged in patients with cirrhosis,and investigate whether QTc is affected by factors such as sex,age,severity,etiology,treatment,acute illness,and liver Tx.METHODS In the present systematic review and meta-analysis,the searching protocol“{[QTc]OR[QT interval]OR[QT-interval]OR[Q-T syndrome]}AND{[cirrhosis]OR[Child-Pugh]OR[MELD]}”was applied in PubMed,EMBASE,and Google Scholar databases to identify studies that reported QTc in patients with cirrhosis and published after 1998.Seventy-three studies were considered eligible.Data concerning first author,year of publication,type of study,method used,sample size,mean age,female ratio,alcoholic etiology of cirrhosis ratio,Child-Pugh A/B/C ratio,mean model for end-stage liver disease(MELD)score,treatment withβ-blockers,episode of acute gastrointestinal bleeding,formula for QT correction,mean pulse rate,QTc in patients with cirrhosis and controls,and QTc according to etiology of cirrhosis,sex,Child-Pugh stage,MELD score,and liver Tx status(pre-Tx/post-Tx)were retrieved.The Newcastle-Ottawa quality assessment scale appraised the quality of the eligible studies.Effect estimates,expressed as proportions or standardized mean differences,were combined using the randomeffects,generic inverse variance method of DerSimonian and Laird.Subgroup,sensitivity analysis,and meta-regressions were applied to assess heterogeneity.RESULTS QTc combined mean in patients with cirrhosis was 444.8 ms[95%confidence interval(CI):440.4-449.2;P<0.001 when compared with the upper normal limit of 440 ms],presenting high heterogeneity(I2=97.5%;95%CI:97.2%-97.8%);both Egger’s and Begg’s tests showed non-significance.QTc was elongated in patients with cirrhosis compared with controls(P<0.001).QTc was longer in patients with Child-Pugh C cirrhosis when compared with Child-Pugh B and A(P<0.001);Child-Pugh B patients presented longer QTc when compared with Child-Pugh A patients(P=0.003).The MELD score was higher in patients with cirrhosis with QTc>440 ms when compared with QTc≤440 ms(P<0.001).No correlation of QTc with age(P=0.693),sex(P=0.753),or etiology(P=0.418)was detected.β-blockers shortened QTc(P<0.001).QTc was prolonged during acute gastrointestinal bleeding(P=0.020).Tx tended to improve QTc(P<0.001).No other sources of QTc heterogeneity were revealed.CONCLUSION QTc is prolonged in cirrhosis independently of sex,age,and etiology but is correlated with severity and affected byβ-blockers and acute gastrointestinal bleeding.QTc is improved after liver Tx.
