RESUMEN

BACKGROUND & AIMS: Survodutide is a glucagon/glucagon-like peptide-1 receptor dual agonist in development for the treatment of metabolic dysfunction-associated steatohepatitis (MASH). We investigated the pharmacokinetic and safety profile of survodutide in people with cirrhosis. METHODS: This multinational, non-randomized, open-label, phase I clinical trial initially evaluated a single subcutaneous dose of survodutide 0.3 mg in people with Child-Pugh class A, B or C cirrhosis and healthy individuals with or without overweight/obesity matched for age, sex, and weight; the primary endpoints were the area under the plasma concentration-time curve from 0 to infinity (AUC0-∞) and maximal plasma concentration (Cmax). Subsequently, people with overweight/obesity with or without cirrhosis (Child-Pugh class A or B) received once-weekly subcutaneous doses escalated from 0.3 mg to 6.0 mg over 24 weeks then maintained for 4 weeks; the primary endpoint was drug-related treatment-emergent adverse events, with MASH/cirrhosis-related endpoints explored. RESULTS: In the single-dose cohorts (n = 41), mean AUC0-∞ and Cmax were similar in those with cirrhosis compared with healthy individuals (90% CIs for adjusted geometric mean ratios spanned 1). Drug-related adverse events occurred in 25.0% of healthy individuals and ≤25.0% of those with cirrhosis after single doses, and 82.4% and 87.5%, respectively, of the multiple-dose cohorts (n = 41) over 28 weeks. Liver fat content, liver stiffness, liver volume, body weight, and other hepatic and metabolic disease markers were generally reduced after 28 weeks of survodutide treatment. CONCLUSIONS: Survodutide is generally tolerable in people with compensated or decompensated cirrhosis, does not require pharmacokinetic-related dose adjustment, and may improve liver-related non-invasive tests, supporting its investigation for MASH-related cirrhosis. IMPACT AND IMPLICATIONS: Survodutide is a glucagon receptor/glucagon-like peptide-1 receptor dual agonist in development for treatment of metabolic dysfunction-associated steatohepatitis (MASH), which causes cirrhosis in ∼20% of cases. This trial delineates the pharmacokinetic and safety profile of survodutide in people with compensated or decompensated cirrhosis, and revealed associated reductions in liver fat content, markers of liver fibrosis and body weight. These findings have potential relevance for people with MASH-including those with decompensated cirrhosis, who are usually excluded from clinical trials of investigational drugs. Based on this study, further investigation of survodutide for MASH-related cirrhosis is warranted. GOV IDENTIFIER: NCT05296733.

RESUMEN

BACKGROUND & AIMS: Hospitalized patients with cirrhosis frequently undergo multiple procedures. The risk of procedural-related bleeding remains unclear, and management is not standardized. We conducted an international, prospective, multicenter study of hospitalized patients with cirrhosis undergoing nonsurgical procedures to establish the incidence of procedural-related bleeding and to identify bleeding risk factors. METHODS: Hospitalized patients were prospectively enrolled and monitored until surgery, transplantation, death, or 28 days from admission. The study enrolled 1187 patients undergoing 3006 nonsurgical procedures from 20 centers. RESULTS: A total of 93 procedural-related bleeding events were identified. Bleeding was reported in 6.9% of patient admissions and in 3.0% of the procedures. Major bleeding was reported in 2.3% of patient admissions and in 0.9% of the procedures. Patients with bleeding were more likely to have nonalcoholic steatohepatitis (43.9% vs 30%) and higher body mass index (BMI; 31.2 vs 29.5). Patients with bleeding had a higher Model for End-Stage Liver Disease score at admission (24.5 vs 18.5). A multivariable analysis controlling for center variation found that high-risk procedures (odds ratio [OR], 4.64; 95% confidence interval [CI], 2.44-8.84), Model for End-Stage Liver Disease score (OR, 2.37; 95% CI, 1.46-3.86), and higher BMI (OR, 1.40; 95% CI, 1.10-1.80) independently predicted bleeding. Preprocedure international normalized ratio, platelet level, and antithrombotic use were not predictive of bleeding. Bleeding prophylaxis was used more routinely in patients with bleeding (19.4% vs 7.4%). Patients with bleeding had a significantly higher 28-day risk of death (hazard ratio, 6.91; 95% CI, 4.22-11.31). CONCLUSIONS: Procedural-related bleeding occurs rarely in hospitalized patients with cirrhosis. Patients with elevated BMI and decompensated liver disease who undergo high-risk procedures may be at risk to bleed. Bleeding is not associated with conventional hemostasis tests, preprocedure prophylaxis, or recent antithrombotic therapy.

RESUMEN

BACKGROUND & AIMS: Genetic ancestry or racial differences in health outcomes exist in diseases associated with systemic inflammation (eg, COVID-19). This study aimed to investigate the association of genetic ancestry and race with acute-on-chronic liver failure (ACLF), which is characterized by acute systemic inflammation, multi-organ failure, and high risk of short-term death. METHODS: This prospective cohort study analyzed a comprehensive set of data, including genetic ancestry and race among several others, in 1274 patients with acutely decompensated cirrhosis who were nonelectively admitted to 44 hospitals from 7 Latin American countries. RESULTS: Three hundred ninety-five patients (31.0%) had ACLF of any grade at enrollment. Patients with ACLF had a higher median percentage of Native American genetic ancestry and lower median percentage of European ancestry than patients without ACLF (22.6% vs 12.9% and 53.4% vs 59.6%, respectively). The median percentage of African genetic ancestry was low among patients with ACLF and among those without ACLF. In terms of race, a higher percentage of patients with ACLF than patients without ACLF were Native American and a lower percentage of patients with ACLF than patients without ACLF were European American or African American. In multivariable analyses that adjusted for differences in sociodemographic and clinical characteristics, the odds ratio for ACLF at enrollment was 1.08 (95% CI, 1.03-1.13) with Native American genetic ancestry and 2.57 (95% CI, 1.84-3.58) for Native American race vs European American race CONCLUSIONS: In a large cohort of Latin American patients with acutely decompensated cirrhosis, increasing percentages of Native American ancestry and Native American race were factors independently associated with ACLF at enrollment.

RESUMEN

INTRODUCTION AND OBJECTIVES: Some studies suggest chronic HCV infection diminishes responses to the anti-HBV vaccine. We evaluated the efficacy of double versus standard dose HBV vaccination among HCV patients without cirrhosis. PATIENTS AND METHODS: 141 adults with untreated chronic HCV were randomized to HBV vaccination with double dose (40µg) or standard dose (20µg) at 0, 1 and 6 months; 70 healthy HCV-negative patients given standard dose served as controls. Vaccine response was defined by anti-HBs ≥10 mIU/mL. RESULTS: 128 patients (60 double, 68 standard doses) completed the study. Patients were of median age 52 years, 61% female, 60% fibrosis <2 of 4, and 76% genotype 1 with median 6-log 10 IU/mL HCV RNA. Overall seroprotection rate was 76.7% (95% CI: 65-87) in the 40µg versus 73.5% (95% CI: 63-84) in the 20µg dose HCV-positive groups (p =0.68) and 91.2% (95%CI:84-99) in HCV-negative controls (p =0.011 and 0.003, respectively). In multivariate logistic regression, vaccine dose (double vs. standard dose) was not associated with vaccine response (OR=0.63, p =0.33). Of 32 HCV-infected patients who were non-responders to 3- doses, 25 received the fourth dose of vaccine. The fourth dose seroconversion rate for the 40µg and 20µg groups were 45.5% and 21.4%, respectively. CONCLUSIONS: In HCV-infected patients without cirrhosis, impaired responses to HBV vaccination cannot be overcome by the use of double dose HBV vaccination, but adding a fourth dose of vaccine for non-responders may be an effective strategy. Other adjuvant measures are needed to enhance seroconversion rates in these patients. TRIAL REGISTER: U 1111-1264-2343 (www.ensaiosclinicos.gov.br).

RESUMEN

INTRODUCTION AND OBJECTIVES: The EncephalApp Stroop Test was developed to more easily diagnose minimal hepatic encephalopathy (MHE). A cut-off of >274.9sec (ONtime+OFFtime) reached a 78% sensitivity and 90% specificity in the validation study, but it has been poorly studied in Brazil. We aim to analyze the usefulness of this diagnostic method and to describe a cut-off value to screen MHE in Brazil. METHODS: In this cross-sectional and single-center study, three positive psychometric tests defined the diagnosis of MHE as the gold standard. We evaluated gender, age, education, familiarity with smartphones, etiology of cirrhosis, Child-Pugh/MELD scores, and previous hepatic encephalopathy (HE). Healthy controls and patients without HE were compared for the task validation. The Chi-square and Mann-Whitney tests, logistic regression analysis, and ROC curves were used for statistical evaluation. RESULTS: We included 132 patients with cirrhosis (61% male) and 42 controls (62% male) around 51y. Sixty-three were diagnosed with MHE on psychometric tests and 23 had clinical HE. Viral hepatitis (38%) was the major etiology of cirrhosis. The median MELD was 10 and Child-Pugh A was more frequent (70%). There was no significant difference in test results between controls and patients without HE. There was also no influence of gender, age, education, and familiarity with smartphones in the test results. Child-Pugh A was associated with MHE (p=0.0106). A cut-off of >269.8sec (ONtime+OFFtime) had an 87% sensitivity and 77% specificity to detect MHE (p=0.002). CONCLUSION: This is a valid and reliable tool for screening MHE. However, optimal cut-off values need to be validated locally.

RESUMEN

Fibroblast growth factor 21 (FGF21) signaling and genetic factors are involved in non-alcoholic fatty liver disease (NAFLD) pathogenesis. However, these factors have rarely been studied in type 2 diabetes mellitus (T2D) patients from admixed populations such as in those of Brazil. Therefore, we aimed to evaluate rs738409 patanin-like phospholipase domain-containing protein (PNPLA3) and rs499765 FGF21 polymorphisms in T2D, and their association with NAFLD, liver fibrosis, and serum biomarkers (FGF21 and cytokeratin 18 levels). A total of 158 patients were included, and the frequency of NAFLD was 88.6%, which was independently associated with elevated body mass index. Significant liver fibrosis (≥F2) was detected by transient elastography (TE) in 26.8% of NAFLD patients, and was independently associated with obesity, low density lipoprotein, and gamma-glutamyl transferase (GGT). PNPLA3 GG genotype and GGT were independently associated with cirrhosis. PNPLA3 GG genotype patients had higher GGT and AST levels; PNPLA3 GG carriers had higher TE values than CG patients, and FGF21 CG genotype patients showed lower gamma-GT values than CC patients. No differences were found in serum values of FGF21 and CK18 in relation to the presence of NAFLD or liver fibrosis. The proportion of NAFLD patients with liver fibrosis was relevant in the present admixed T2D population, and was associated with PNPLA3 polymorphisms.

RESUMEN

INTRODUCTION: Although the use of non-invasive methods for assessment of liver fibrosis has reduced the need for biopsy, the diagnosis of liver damage still requires histological evaluation in many patients. We aim to describe the indications for percutaneous liver biopsy (PLB) and the rate of complications in an outpatient setting over 5 years. METHODS: This observational, single-center, and retrospective study included patients submitted to real-time ultrasound (US)-guided biopsies from 2015 to 2019. We collected age, gender, coagulation tests, comorbidities, and the number of needle passes. The association between the variables and complications was evaluated using the generalized estimating equations method. RESULTS: We analyzed 532 biopsies in 524 patients (55.3% male) with a median age of 49 years (range 13-74y). An average of 130.3 biopsies per year were performed in the first 3 years of the study versus 70.5 in the other 2y. The main indications were hepatitis C virus (HCV) infection (47.0%), autoimmune and cholestatic liver diseases (12.6%), and metabolic dysfunction-associated fatty liver disease (MAFLD) (12.1%). The number of HCV-related biopsies had a remarkable reduction, while MAFLD-related procedures have progressively raised over time. Around 54% of the patients reported pain, which was significantly associated with females (p=0.0143). Serious complications occurred in 11 patients (2.1%) and hospital admission was necessary in 10 cases (1.9%). No patient required surgical approach and there were no deaths. No significant association was found between the studied variables and biopsy-related complications. CONCLUSION: The indications for PLB in an outpatient setting have changed from HCV to MAFLD over the years. This procedure is safe and has a low rate of serious complications, but new strategies to prevent the pain are still needed, especially for females.

RESUMEN

BACKGROUND: Despite the growing body of knowledge about TM6SF2 and PNPLA3 polymorphisms in non-alcoholic fatty liver disease, their influence in the spectrum of HCV liver disease is not yet fully defined. Besides that, admixed populations, such as Brazilians, were not included in most of the studies. METHODS: This cross-sectional study enrolled 365 treatment-naïve patients with HCV and 134 healthy individuals. TM6SF2 (rs58542926 c.499C > T) and PNPLA3 (rs738409 c.444C > G) polymorphisms were evaluated regarding their association with clinical and laboratory data, histological liver steatosis and fibrosis, and with components of the metabolic syndrome. RESULTS: In HCV subjects, the frequencies of TM6SF2 CC and CT + TT were 89% and 11%, while PNPLA3 frequencies of CC and CG + GG were 51.4% and 48.6%. In the univariate logistic regression analysis, the TM6SF2 CT + TT genotype in HCV was associated with significant liver fibrosis (p = 0.047; OR 1.953; 95% CI 1.009-3.788). In comparison to the CT + TT genotype, the TM6SF2 CC genotype in HCV was associated with older age (p = 0.002), higher frequency of arterial hypertension (p = 0.032), obesity (p = 0.030), metabolic syndrome (p = 0.014) and lower total cholesterol levels (p = 0.036). The PNPLA3 GG subjects had lower body mass index than CG/ CC individuals (p = 0.047). None of the polymorphisms, or their combinations, was independently associated with hepatic steatosis or fibrosis. On the other hand, older age, lower serum levels of total cholesterol, and higher serum levels of alanine aminotransferase and alkaline phosphatase were associated with liver fibrosis in the multivariate logistic regression analysis. CONCLUSION: In this evaluation of an admixed HCV population, neither TM6SF2 nor PNPLA3 polymorphisms were independently associated with hepatic steatosis or fibrosis. Other factors seem more influential than these specific polymorphisms in isolation. More studies are warranted to clarify the role of the TM6SF2 and PNPLA3 polymorphisms in Brazilians with HCV.

RESUMEN

BACKGROUND: Direct access endoscopy (DAE) is the procedure performed without the pre-evaluation of the patient by a specialist. It is widely available in many medical services around the world, but there is lack of data about this strategy in the setting of the public health system in Brazil. Therefore, the aim of this study is to compare the main endoscopic findings of upper gastrointestinal endoscopy requested through DAE and by specialists. METHODS: Longitudinal, retrospective single center study in patients who underwent upper digestive endoscopy in a public healthcare facility at the southern region of the state of Mato Grosso, Brazil, from August 2011 to December 2018. Age, gender, modality of endoscopy request (DAE or endoscopy requested by specialists), and endoscopic findings were analyzed. RESULTS: A total of 2810 patients were included. Most of them were female 65.23% (1833), mean age was 47.36 years, and 50.71% of the exams (1425) were DAE. Only 4.62% of the exams had normal reports. The most frequent endoscopic findings were gastritis (91.99%), bulboduodenitis (43.59%) and reflux esophagitis (14.76%). Patients who underwent endoscopy requested by specialists were older (50.25 ± 16.57 vs. 44.55 ± 16.31 years, p < .0001) and more frequently men (36.61 vs. 32.98%, p = .0437) in comparison to DAE. However, endoscopic findings were similar in both groups. CONCLUSION: This study shows that direct access upper endoscopy had comparable results to specialist requested endoscopy in a public healthcare facility in the southern region of the state of Mato Grosso, Brazil.

RESUMEN

Vanishing bile duct syndrome is a rare acquired condition, characterized by progressive loss of intrahepatic bile ducts leading to ductopenia and cholestasis. It can be associated with infections, ischemia, drug adverse reactions, neoplasms, autoimmune disease, and allograft rejection. Prognosis is variable and depends on the etiology of bile duct injury. We report the case of a 25-year-old female with cholestatic hepatitis and concomitant intakes of hepatotoxic substances, such as garcinia, field horsetail, and ketoprofen. On suspicion of a drug-induced liver injury, the drugs were promptly withdrawn and ursodeoxycholic acid was started with initial clinical and laboratory improvement, and the patient was discharged from the hospital. One month later, she had a new increase in bilirubin levels and canalicular enzymes, requiring a liver biopsy that showed significant loss of intrahepatic bile ducts, which was compatible with vanishing bile duct syndrome. This was confirmed by using cytokeratin 19 on immunohistochemistry. There was subsequent lymph node enlargement in several chains, and relevant weight loss. Histological analysis of a cervical lymph node revealed nodular sclerosis-subtype classic Hodgkin lymphoma. In this setting, vanishing bile duct syndrome was related to Hodgkin lymphoma and a drug-induced liver injury overlap, leading to progressive cholestasis with a worse prognosis. The patient's response to chemotherapy was poor, requiring biological therapy with brentuximab vedotin. It is crucial for physicians to create a broad differential diagnosis in suspected vanishing bile duct syndrome patients, especially to rule out malignancies.
