ABSTRACT

Abstract BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) has become a public health problem worldwide. Neck circumference (NC) is a simple anthropometric adiposity parameter that has been correlated with cardiometabolic disorders like NAFLD. OBJECTIVES: To investigate the association between NC and NAFLD, considering their obesity-modifying effect, among participants from the Longitudinal Study of Adult Health (ELSA-Brasil) baseline study. DESIGN AND SETTINGS: Cross-sectional study at the ELSA-Brasil centers of six public research institutions. METHODS: This analysis was conducted on 5,187 women and 4,270 men of mean age 51.8 (± 9.2) years. Anthropometric indexes (NC, waist circumference [WC] and body mass index [BMI]), biochemical and clinical parameters (diabetes, hypertension and dyslipidemia) and hepatic ultrasound were measured. The association between NC and NAFLD was estimated using multinomial logistic regression, considering potential confounding effects (age, WC, diabetes, hypertension and dyslipidemia). Effect modification was investigated by including the interaction term NC x BMI in the final model. RESULTS: The frequency of NAFLD and mean value of NC were 33.6% and 33.9 (± 2.5) cm in women, and 45.8% and 39.4 (± 2.8) cm in men, respectively. Even after all adjustments, larger NC was associated with a greater chance of moderate/severe NAFLD (1.16; 95% confidence interval [CI] for women; 1.05, 95% CI for men; P < 0.001). Presence of multiplicative interaction between NC and BMI (P < 0.001) was also observed. CONCLUSION: NC was positively associated with NAFLD in both sexes, regardless of traditional adiposity indexes such as BMI and WC. The magnitude of the association was more pronounced among women.

ABSTRACT

Hepatic ischemia-reperfusion injury (HIRI) is a very common complication of liver transplantation, liver resection, and shock. At present, many studies have been conducted on HIRI, but there is still a lack of drugs for radical treatment in clinical practice. Many factors, such as related cells, molecular mechanisms and signaling pathways, reactive oxygen species and oxidative stress response, nitric oxide, and mitochondria, mediate the development and progression of HIRI, which leads to the decline of patients' quality of life and even endangers their life safety. Based on the pathogenesis of HIRI and related articles, this article summarizes the research advances in the prevention and treatment of HIRI with traditional Chinese medicine components, so as to provide theoretical support for basic research and clinical research on HIRI.

ABSTRACT

Objective To investigate the effect of the mitochondria-targeted antioxidant SS-31 on acute liver injury in a mouse model of sepsis. Methods A total of 24 adult male C57BL/6J mice were randomly divided into control group, control+SS-31 group, lipopolysaccharide (LPS) group, and LPS+SS-31 group, with 6 mice in each group. The mice were given intraperitoneal injection of LPS (10 mg/kg) to establish a model of sepsis and acute liver injury, followed by intraperitoneal injection of SS-31 (10 mg/kg) for treatment, and the mice in the control group were given intraperitoneal injection of an equal volume of PBS solution, followed by intraperitoneal injection of an equal volume of normal saline. After 12 hours, ELISA was used to measure the levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), reactive oxygen species (ROS), superoxide dismutase (SOD), tumor necrosis factor-α (TNFα), interleukin-1β(IL-1β), and interleukin-6 (IL-6), and HE staining was used to observe liver histopathological changes. A one-way analysis of variance was used for comparison of continuous data between multiple groups, and the least significant difference t -test was used for further comparison between two groups. Results Compared with the LPS group, the LPS+SS-31 group had significant reductions in the serum levels of ALT (140.05±12.22 U/L vs 102.64±8.75 U/L, P < 0.05) and AST (80.22±4.71 U/L vs 69.26±5.37 U/L, P < 0.05) and the levels of ROS (1 030.21±115.87 pg/mL vs 847.84±63.65 pg/mL, P < 0.05), TNFα (767.18±60.60 ng/mL vs 698.89±16.99 ng/mL, P < 0.05), IL-1β (29.97±1.37 ng/mL vs 26.70±3.09 ng/mL, P < 0.05), and IL-6 (59.13±7.09 pg/mL vs 49.29±3.41 pg/mL, P < 0.05) in liver tissue. Compared with the control group based on HE staining, the LPS group showed destruction of hepatic lobular structure, inflammatory cell infiltration, ambiguous intercellular space, and hepatocyte swelling, while the LPS+SS-31 group showed alleviation of inflammatory cell infiltration and hepatocyte swelling. Conclusion The mitochondria-targeted antioxidant SS-31 can reduce the production of ROS, downregulate the highly expressed inflammatory factors in sepsis, and alleviate sepsis-related acute liver injury in mice.

ABSTRACT

Objective To establish the intelligent identification method for the big data of liver injury-related adverse drug reaction (ADR) based on the construction of text database. Methods With the keywords including "drug-induced liver injury" and "abnormal liver function" and a search time of January 1, 2012 to December 31, 2016, 5% (4152 cases) of the case reports of liver injury-related ADR were retrieved and extracted from the China Adverse Drug Reaction Monitoring System, and then based on clinical reevaluation by physicians, these cases were classified into "negative cases", "suspected cases", and "confirmed cases". On this basis, key elements (including ADR name, biochemical parameter, and clinical symptoms) were identified. An intelligent identification method for liver injury-related ADR was established based on the correlation analysis between key elements and clinical reevaluation and the receiver operating characteristic (ROC) curve for determining cut-off values, and the method of cross validation was used to evaluate the performance of this intelligent identification method. Results The formula for the evaluation and identification of liver injury-related ADR was as follows: total score (M)=symptom score+index score+ADR name score. This formula showed the best discriminatory ability to distinguish "negative case" from "suspected case" or "confirmed case" at M=5 (area under the ROC curve [AUC]=0.97), with a sensitivity of 99.57% and a specificity of 84.61%, and it showed the best discriminatory ability to distinguish "confirmed case" from "suspected case" or "negative case" at M=12 (AUC=0.938), with a sensitivity of 87.93% and a specificity of 85.98%. Conclusion This method provides reference and basis for intelligent identification and evaluation of big data on liver injury-related ADR and is expected to effectively reduce the burden of manual processing of ADR big data and provide effective tools and methodological demonstration for early risk signal identification and warning of liver injury-related ADR.

ABSTRACT

The prognosis of severe liver disease combined with invasive fungal infection (IFI) is poor, and the clinical manifestations are often atypical. Moreover, most of the antifungal drugs are metabolized in the liver, with severe toxicities and side effects, making clinical diagnosis and treatment difficult. The Professional Committee for Hepatology, the Chinese Research Hospital Association and the Hepatology Branch of China Medical Association organized relevant experts to formulate an expert consensus based on the characteristics of patients with severe liver disease combined with IFI, in order to provide reference for medical personnel in making decisions on the diagnosis and treatment.

ABSTRACT

Intrahepatic cholestasis is a clinical syndrome due to the defect of bile acid synthesis, abnormal bile excretion, and mechanical or functional disturbance of intrahepatic bile flows caused by hepatic parenchymal cell and/or intrahepatic bile duct diseases. It commonly occurs as cholestatic liver diseases, intrahepatic cholestasis of pregnancy, and genetic/metabolic-related cholestatic diseases. In recent years, new information and progress in diagnosis and treatment of intrahepatic cholestatic diseases have been achieved. In order to provide updated clinical reference and guidance for clinicians, we organized experts to compile the Expert Consensus on the Diagnosis and Treatment of Intrahepatic Cholestasis (2021), on the basis of the 2015 edition.

ABSTRACT

Thymic stromal lymphopoietin (TSLP) is a type I interleukin 2 family cytokine composed of four short-chain α-helix bundles and has homology with interleukin-7. TSLP plays an important role in many allergic diseases or autoimmune diseases, such as asthma, atopic dermatitis, eosinophilic esophagitis, and inflammatory bowel disease, and promotes the development of these diseases. At present, there are some reports on TSLP in liver diseases, and some studies showed that it can promote the development and progression of liver diseases, while others showed that it plays a protective role in liver diseases. This article reviews the molecular composition and biological features of TSLP and the role of TSLP in benign liver diseases and liver tumors and elaborates on the research advances in TSLP in liver diseases.

ABSTRACT

Indoleamine 2, 3-dioxygenase (IDO) is an important immunoregulatory enzyme, which can degrade the level of the mammalian essential amino acid tryptophan (TRP), catalyze the initiation and rate-limiting steps through the kynurenine pathway, and produce a variety of metabolites to participate in the immune response. On the one hand, IDO plays an immunosuppressive role in microenvironment and thus leads to infection and immune escape of tumor cells; on the other hand, IDO also exerts an inhibitory effect on the pathogens such as bacteria and parasites and thus protects the body from the harm of pathogens to a certain extent. Therefore, IDO is considered an important medium with the role of a double-edged sword in the development and progression of various liver diseases. This article reviews the latest research advances in IDO in viral hepatitis, liver fibrosis, liver cirrhosis, liver cancer, and hepatic echinococcosis.

ABSTRACT

Inflammasomes play an important role in the innate immunity of the liver; however, the excessive activation of inflammasomes can lead to liver inflammation and injury. The mechanism of nucleotide-binding oligomerization domain-like receptor protein 3 (NLRP3) inflammasome-mediated liver injury has been extensively studied. Related studies have shown that the development of various liver diseases may be associated with the excessive activation of inflammasomes, especially NLRP3 inflammasome. This article reviews inflammasomes, the activation mechanism of NLRP3 inflammasome, and the role of NLRP3 inflammasome in different liver diseases, so as to provide a reference for the treatment targets of liver diseases from the perspective of NLRP3 inflammasome.

ABSTRACT

Objective To investigate the articles on liver diseases published by authors from China (excluding Hong Kong, Macao, and Taiwan regions) in Gastroenterology & Hepatology journals indexed in Science Citation Index Expanded (SCIE) in 2016-2020, to analyze the bibliographic and citation data of these articles, and to understand the contribution and impact of Chinese scholars in the field of liver disease research in recent years. Methods The data for bibliometric analysis came from the SCIE database and Journal Citation Reports (JCR). The SCIE database was searched for the journal articles published in JCR Gastroenterology & Hepatology journals in 2016-2020, with a title or abstract containing "Liver", "Hepatocellular", "Hepatitis", "Cirrhosis", or "Hepatic" and a publication type of Article. Clinical guidelines were excluded, and the records with the corresponding author's affiliation containing institutions in China (excluding Hong Kong, Macao, and Taiwan regions) were screened out. R package bibliometrix was used to calculate the frequency of citations of included articles by liver disease studies published by Chinese and global authors in the Gastroenterology & Hepatology journals in 2016-2020, and R package DescTools was used to perform the Cochran-Armitage trend test to observe the change in composition ratio. Results In the Q1 Gastroenterology & Hepatology journals in 2016-2020, liver disease studies published by Chinese authors accounted for 9.5%. In recent years, the proportion of liver disease studies published by Chinese authors in Q1 Gastroenterology & Hepatology journals continues to increase from 6.0% to 12.2% ( P < 0.001). Among the liver disease studies published by Chinese authors in Q1 Gastroenterology & Hepatology journals, 79.7% were funded by National Natural Science Foundation of China, and there was no significant change in the proportion of studies funded by National Natural Science Foundation of China and published by Chinese authors in each partition of Gastroenterology & Hepatology journals in 2016-2020. The frequency of citations of included articles by liver disease studies published by Chinese and global authors in the Gastroenterology & Hepatology journals showed that liver disease studies published by Chinese authors had a high impact in both domestic and international academic communities. Conclusion In recent years, there has been a constant increase in the number of liver disease studies published by Chinese authors in high-impact Gastroenterology & Hepatology journals indexed in SCIE, and most of these studies have been funded by National Natural Science Foundation of China. The liver disease studies published by Chinese authors in Gastroenterology & Hepatology journals have been widely recognized by domestic and international academic communities.

ABSTRACT

IgG4-related hepatobiliary and pancreatic diseases are a part of the IgG4-related disease multiorgan fibroinflammatory disorder, including IgG4-related autoimmune pancreatitis, IgG4-related sclerosing cholangitis, and IgG4-related hepatic involvement. The main pathological features include IgG4 + plasma cell/lymphocyte infiltration, storiform fibrosis, obliterative phlebitis, and eosinophil infiltration. The diagnosis of this disease is often based on the comprehensive diagnostic criteria for IgG4-related diseases and organ-specific diagnostic criteria. However, it is difficult to differentiate IgG4-related hepatobiliary and pancreatic diseases from neoplastic diseases, and novel diagnostic biomarkers are expected to improve the sensitivity and specificity of diagnosis. To date, glucocorticoids remain the first-line drug for this disease, and biological agents, especially anti-CD20 monoclonal antibody, may be an alternative therapy for patients with corticosteroid contraindication/intolerance or recurrent/refractory disease.

ABSTRACT

ABSTRACT - BACKGROUND: Hydatidosis is a rare and endemic parasitic disease in Brazil that causes the proliferation of cysts mainly in the liver, leading to many complications, such as compression of vessels and biliary ducts, liver failure, portal hypertension, and cirrhosis. The treatment of choice is the resection of the lesions combined with albendazole therapy. This disease is a rare indication for liver transplantation, a feasible treatment option in more advanced stages. AIM: The purpose of this study was to describe two cases of patients from northern Brazil who underwent liver transplantation due to hepatic hydatidosis. METHODS: This is a retrospective study with data collected from medical records. RESULTS: Case 1: A 51-year-old female patient presented pain in the right hypochondriac, dyspepsia, consumptive syndrome, and obstructive jaundice, with a previous diagnosis of Caroli's disease with no possibility of surgical resection and a MELD score of 24. She underwent liver transplantation, and the anatomopathological result demonstrated hydatidosis. Case 2: A 52-year-old female patient presented multiple episodes of cholangitis in 30 years, with three liver resections and clinical treatment with albendazole for hydatidosis. She underwent liver transplantation due to recurrent cholangitis with a MELD score of 20. Both patients underwent post-transplant clinical therapy with albendazole, had good outcomes, and remain in follow-up without complications after 5 and 96 months, respectively. CONCLUSION: The patients benefited from the procedure and have a good prognosis due to the absence of metastasis, early reintroduction of antiparasitic drugs, and continuous follow-up.


RESUMO - RACIONAL: A hidatidose é uma doença parasitária rara, endêmica no Brasil, que causa a proliferação de cistos, principalmente no fígado, levando a muitas complicações, como compressão de vasos e ductos biliares, hipertensão portal e cirrose. O tratamento ideal é a ressecção cirúrgica das lesões combinada à terapia com albendazol. Essa doença é uma rara indicação para o transplante hepático, que é um possível tratamento para estágios avançados. OBJETIVO: Descrever dois casos de pacientes provenientes da região Norte do Brasil, que foram submetidos a transplante hepático por hidatidose hepática. MÉTODOS: Estudo retrospectivo com coleta de dados de prontuários. RESULTADOS: Caso 1: Paciente do sexo feminino de 51 anos, apresentava dor em hipocôndrio direito, sintomas dispépticos, síndrome consumptiva e icterícia obstrutiva, com diagnóstico inicial de doença de Caroli sem possibilidade de ressecção cirúrgica e com MELD 24. Foi submetida a transplante hepático, e o resultado anatomopatológico do explante evidenciou hidatidose. Caso 2: Paciente do sexo feminino de 52 anos, apresentava há cerca de 30 anos, múltiplos episódios de colangite, com realização de três ressecções hepáticas e tratamento clínico com albendazol para hidatidose. Foi submetida a transplante hepático por equinococose alveolar difusa, com situação especial por colangite de repetição, com MELD 20. Ambas fizeram tratamento clínico pós transplante com albendazol, apresentaram boas evoluções e permanecem em acompanhamento sem complicações após 5 e 96 meses, respectivamente. CONCLUSÃO: As pacientes se beneficiaram do procedimento e têm bom prognóstico, devido à ausência de metástases, reintrodução precoce das drogas antiparasitárias e acompanhamento contínuo.

ABSTRACT

ABSTRACT Liver transplantation is the major treatment for end-stage liver disease. Postoperative care is a great challenge to reduce morbidity and mortality in patients. In this sense, management in the liver ICU allows hemodynamic management, coagulation monitoring, renal support, electrolyte disturbances, respiratory support and early weaning from mechanical ventilation and evaluation of the liver graft. Objective: The present study shows the results of the management of liver transplant patients in 20 years of experience in a transplant center in a low- to middle-income country. Materials and methods: The medical records of 273 adult patients in the ICU in the immediate postoperative liver transplant were reviewed, from March 20, 2000 to November 30, 2020, including the effect of the pandemic caused by COVID-19. Liver-kidney, retransplanted, SPLIT, and domino transplant patients were excluded. Results: The most frequent etiology for LTx was NASH (35%), the mean age was 49 years, MELD Score ranged 15 - 20 (47.5%), 21 - 30 (46%) > 30 (6.2%). ICU pre transplant stay 7%, average ICU stay: 7.8 days. APACHE average admission: 14.9 points. Weaning extubation of 91.8% patients in ICU and Fast Track in 8.2%. The most frequent respiratory complication was atelectasis 56.3%, pneumonia (31.3%); AKI 1 (60.9%), and 11.1% with hemodyalisis support (AKI3). Immunosuppression: Tacrolimus (8.9%). Post-operative ICU mortality was 6.2%. Conclusions: The management of liver transplantation in the ICU is essential to achieve optimal results in patients who present advanced liver disease and require advanced life support in the immediate postoperative period and thus optimize graft survival.

ABSTRACT

Introdution: Chronic liver diseases are characterized by inflammatory and fibrotic lesions of the liver that cause systemic complications. These complications can negatively interfere with the respiratory muscle strength and exercise capacity of developing children and adolescents. Objectives: to compare respiratory muscle strength and exercise capacity in children and adolescents with chronic hepatopathy, using predicted values from healthy individuals of the same age. Methodology: a cross-sectional study was performed. Children and adolescents from 6 to 16 years old with chronic hepatopathies were included. For the evaluation of respiratory muscle strength, the maximal respiratory pressures were measured through manovacuometry. A six-minute walk test was used to assess exercise capacity. The Wilcoxon test was used to verify the difference between the evaluated and predicted values of the distance traveled. Results: In total, 40 subjects were analyzed; 57.5% of the subjects were female, and the subjects had a mean age of 11.68±2.82 years. In the comparison between the measured and predicted maximal respiratory pressures, a median (IQR) difference of -21,47 (33-95) cmH2O (p< 0.001) was found for the maximal inspiratory pressure, and a mean difference of 30.68±17,16 cmH2O (p< 0.001) was found for the maximal expiratory pressure. Regarding exercise capacity, the measured average distance traveled was 346.46±49.21 m, which was 185.54±63,90 m (p< 0.001) less than the predicted value. Conclusion: Children and adolescents with chronic liver disease have reduced respiratory muscle function and exercise capacity.

ABSTRACT

Abstract Objective: To evaluate variables affecting the need for analgesia after ultrasound-guided percutaneous liver biopsy performed on an outpatient basis. Materials and Methods: This was a retrospective analysis of 1,042 liver biopsies performed between 2012 and 2018. The data collected included the age and sex of the patient, as well as self-reported pain in the recovery room, the pain treatment used, the indication for the biopsy, and the lobe punctured. As per the protocol of our institution, physicians would re-evaluate patients with mild pain (1-3 on a visual analog scale), prescribe analgesics for those with moderate pain (4-6 on the visual analog scale), and prescribe opioids for those with severe pain (7-10 on the visual analog scale). Results: The main indications for biopsy were related to diffuse disease (in 89.9%), including the follow-up of hepatitis C (in 47.0%) and suspicion of nonalcoholic steatohepatitis (in 38.0%). Pain requiring analgesia occurred in 8.0% of procedures. Of the 485 female patients, 51 (10.5%) needed analgesia, compared with 33 (5.9%) of the 557 male patients (p < 0.05). The need for analgesia did not differ in relation to patient age, the lobe punctured, or the indication for biopsy (nodular or diffuse disease). The analgesic most commonly used was dipyrone (in 75.9%), followed by paracetamol alone (16.4%) and their combination with opioids (7.6%). Conclusion: Ultrasound-guided percutaneous liver biopsy is safe and well tolerated. Postprocedural pain does not correlate with the lobe punctured, patient age, or the indication for biopsy and appears to affect more women than men.


Resumo Objetivo: Avaliar variáveis que afetam a necessidade de analgesia após biópsia hepática guiada por ultrassonografia. Materiais e Métodos: Análise retrospectiva de 1042 biópsias hepáticas realizadas entre 2012 e 2018. Os dados coletados incluíram dor detectada na sala de recuperação, analgesia utilizada, indicação, lobo puncionado, idade e sexo do paciente. O protocolo institucional indicava orientações e reavaliação para dor leve (1-3, segundo a escala visual analógica), analgésicos simples para dor moderada (4-6, segundo a escala visual analógica) e opioides para dor importante (7-10, segundo a escala visual analógica). Resultados: As indicações foram principalmente doença difusa (89,9%), particularmente no seguimento de hepatite C (47,0%) e suspeita de esteato-hepatite não alcoólica (38,0%). Dor com necessidade de analgesia ocorreu em 8,0% dos procedimentos. Mulheres demandaram analgesia em 10,5% das vezes e homens demandaram em 5,9% (p < 0,05). Não houve diferença estatisticamente significante na necessidade de analgesia em relação a idade, lobo hepático puncionado ou indicação por doença nodular versus difusa. O analgésico mais utilizado foi dipirona (75,9%), seguido de paracetamol (16,4%) e associação com opioides (7,6%). Conclusão: Este é um procedimento seguro e bem tolerado. Dor pós-procedimento não se correlaciona com lateralidade da biópsia, idade ou doença nodular versus difusa e parece afetar mais mulheres que homens.

ABSTRACT

MicroRNA (miRNA) is a type of small non-coding RNA and acts as a post-transcriptional regulator of gene expression. This article briefly describes the etiology of various chronic liver diseases, including metabolic dysfunction-associated fatty liver disease, chronic hepatitis B, chronic hepatitis C, chronic drug-induced liver injury, liver cirrhosis, and hepatocellular carcinoma, and summarizes related reports on microRNA-125b which enters different signal transduction pathways and plays the same or contradictory regulatory role in the same liver disease or pathological process by targeting different target genes, so as to provide insights into the research on the pathogenesis of various chronic liver diseases and the establishment of non-invasive differential methods.

ABSTRACT

Chronic liver diseases can progress to liver fibrosis and cirrhosis and may lead to portal hypertension and even hepatocellular carcinoma. In recent years, more and more studies have shown that statins can improve liver histology, delay progression to liver fibrosis, and reduce the risk of decompensation and hepatocellular carcinoma in patients with nonalcoholic fatty liver disease. This article introduces the advances in the application of statins in patients with chronic liver diseases, so as to provide a basis for the prevention and treatment of chronic liver diseases.

ABSTRACT

ObjectiveTo investigate the association of high-density lipoprotein cholesterol (HDL-C) with the prognosis of patients with alcohol-related hepatocellular carcinoma (HCC) after radical treatment. MethodsA retrospective analysis was performed for the clinical data of 43 patients with alcohol-related HCC who were admitted to The Fifth Medical Center of Chinese PLA General Hospital and underwent radical treatment from January 2008 to July 2015, and according to HDL-C level, the patients were divided into normal group with 26 patients and abnormal group with 17 patients. The two groups were compared in terms of basic information, laboratory markers, imaging indices, Barcelona Clinic Liver Cancer tumor stage, and Child-Pugh class of liver function. The t-test test was used for comparison of normally distributed continuous data between two groups, and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups; the chi-square test was used for comparison of categorical data between two groups. The Kaplan-Meier method was used to plot survival curves and the log-rank test was used for comparison between groups. Univariate and multivariate Cox proportional hazards models were used to analyze independent risk factors for prognosis. ResultsThere was a significant difference in prealbumin between the two groups (162.38±60.86 mg/L vs 120.06±64.08 mg/L, t=2.184, P=0.035). Number of tumors (hazard ratio [HR]=2.839, 95%confidence interval [CI]: 1.120~7.200,P=0.028), tumor size (HR=2.634, 95%CI: 1.062~6.529,P=0037), and HDL-C level (HR=2.400, 95%CI: 1.040~5.537,P=0.040) were independent risk factors for the overall survival of patients with alcohol-related HCC. There were significant differences in 1-, 3-, and 5-year cumulative survival rates between the normal group and the abnormal group (88.5%/72.4%/55.7% vs 70.6%/43.7%/17.5%, χ2=5.881, P=0.015). ConclusionThe reduction in HDL-C level might indicate poor prognosis of patients with alcohol-related HCC.
