Endoscopic Glue Injection vs Glue Plus BRTO or TIPSS for Preventing Gastric Variceal Bleeding: A Randomized Controlled Trial. Clin Gastroenterol Hepatol 2024:S1542-3565(24)00593-7. [PMID: 38969074 DOI: 10.1016/j.cgh.2024.06.023] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/08/2024] [Revised: 06/18/2024] [Accepted: 06/18/2024] [Indexed: 07/07/2024]
Abstract
BACKGROUND AND AIMS The study sought to compare the efficacy of endoscopic injection sclerotherapy with cyanoacrylate glue (EIS-CYA) vs EIS-CYA plus a radiologic intervention (RI) (either transjugular intrahepatic portosystemic shunt or balloon-occluded retrograde transvenous obliteration) for secondary prophylaxis in patients with liver cirrhosis who presented with acute variceal bleeding from cardiofundal varices. Primary outcome measure was gastric varix (GV) rebleed rates at 1 year. METHODS Consecutive cirrhosis patients with acute variceal bleeding from cardiofundal varices were randomized into 2 arms (45 in each) after primary hemostasis by EIS-CYA. In the endoscopic intervention (EI) arm, EIS-CYA was repeated at regular intervals (1, 3, 6, and 12 months), while in the RI arm, patients underwent transjugular intrahepatic portosystemic shunt or balloon-occluded retrograde transvenous obliteration followed by endoscopic surveillance. RESULTS GV rebleed rates at 1 year were higher in the EI arm compared with the RI arm: 11 (24.4%; 95% confidence interval [CI], 12.9%-39.5%) vs 1 (2.2%; 95% CI, 0.1%-11.8%) (P = .004; absolute risk difference: 22.2%; 95% CI, 8.4%-36.6%). GV rebleed-related mortality in the EI arm (8 [17.8%; 95% CI, 8.0%-32.1%]) was significantly higher than in the RI arm (1 [2.2%; 0.1%-11.8%]) (P = .030; absolute risk difference: 15.6; 95% CI, 2.9%-29.2%); however, there was no difference in all-cause mortality between the 2 groups (12 [26.7%; 95% CI, 14.6%-41.9%] vs 7 [15.6%; 95% CI, 6.5%-29.5%]). The number needed to treat to prevent 1 GV-related rebleed at 1 year was 4.5. CONCLUSIONS RI for secondary prophylaxis reduces rebleeding from GV and GV rebleeding-related mortality in patients with GV hemorrhage. (CTRI/2021/02/031396).

Abstract
BACKGROUND Non-cirrhotic portal hypertension (NCPH) is a spectrum of liver diseases, including porto-sinusoidal vascular disorder, with portal hypertension (PH) in the absence of cirrhosis. The natural history and diagnostic approach to NCPH are not well understood. AIM We aimed to evaluate disease progression and outcomes in NCPH. METHODS Patients with or at risk for NCPH were enrolled in a single centre prospective study; two groups were formed based on the presence of specific features of PH, such as varices, collaterals, portal hypertensive gastropathy or portal hypertensive bleeding. All participants underwent a baseline liver biopsy. Liver stiffness measurement (LSM), and imaging were repeated every 6-12 months. RESULTS Fifteen patients without specific features of PH (Group I), and 35 patients with specific features (Group II) were enrolled. The median follow-up time was 50 months. Group II had higher hepatic venous pressure gradients, non-invasive measures of PH and a lower platelet count (PLT) when compared to Group I. Rates of survival and decompensation were similar in both groups. Patients with PLT ≤100 K/mcL had lower survival compared to those with PLT >100 K/mcL. Patients with LSM ≥10 kPa had lower survival and survival without decompensation when compared to patients with LSM <10 kPa. CONCLUSIONS Patients irrespective of specific features of PH had similar survival or survival without decompensation. Patients without specific features are at risk for disease progression and should be monitored closely. Thrombocytopenia and increased LSM are associated with severe forms of liver disease, which are strongly associated with outcomes.

World J Hepatol 2023; 15:89-106. [PMID: 36744166 PMCID: PMC9896508 DOI: 10.4254/wjh.v15.i1.89] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/25/2022] [Revised: 11/17/2022] [Accepted: 01/01/2023] [Indexed: 01/16/2023] Open
Abstract
BACKGROUND Liver disease incidence and hence demand on hepatology services is increasing.
AIM To describe trends in incidence and natural history of liver diseases in Wales to inform effective provision of hepatology services.
METHODS The registry is populated by International Classification of Diseases-10 (ICD-10) code diagnoses for residents derived from mortality data and inpatient/day case activity between 1999-2019. Pseudo-anonymised linkage of: (1) Causative diagnoses; (2) Cirrhosis; (3) Portal hypertension; (4) Decompensation; and (5) Liver cancer diagnoses enabled tracking liver disease progression.
RESULTS The population of Wales in 2019 was 3.1 million. Between 1999 and 2019 73054 individuals were diagnosed with a hepatic disorder, including 18633 diagnosed with cirrhosis, 10965 with liver decompensation and 2316 with hepatocellular carcinoma (HCC). Over 21 years the incidence of liver diseases increased 3.6 fold, predominantly driven by a 10 fold increase in non-alcoholic fatty liver disease (NAFLD); the leading cause of liver disease from 2014. The incidence of cirrhosis, decompensation, HCC, and all-cause mortality tripled. Liver-related mortality doubled. Alcohol-related liver disease (ArLD), autoimmune liver disease and congestive hepatopathy were associated with the highest rates of decompensation and all-cause mortality.
CONCLUSION A 10 fold increase in NAFLD incidence is driving a 3.6 fold increase in liver disease in Wales over 21 years. Liver-related morbidity and mortality rose more slowly reflecting the lower progression rate in NAFLD. Incidence of ArLD remained stable but was associated with the highest rates of liver-related and all-cause mortality.

Abstract
We herein report a case of gastric hyperplastic polyps after argon plasma coagulation (APC) for gastric antral vascular ectasia (GAVE) in the antrum of a 65-year-old man with liver cirrhosis and hypergastrinemia induced by long-term proton pump inhibitor (PPI) use. Two years after APC therapy, endoscopy demonstrated multiple gastric polyps in the antrum and angle. A gastric polyp biopsy indicated foveolar epithelium hyperplasia, which was diagnosed as gastric hyperplastic polyps. One year after switching to an H2 blocker antagonist, endoscopy revealed that the polyps and GAVE had disappeared, with normal gastrin levels suggesting that PPI-induced hypergastrinemia had caused gastric hyperplastic polyps after APC therapy, and the polyps had disappeared after discontinuing PPIs.

Abstract
Complications of portal hypertension include portal hypertensive gastropathy and colopathy. These disorders may cause chronic or acute gastrointestinal bleeding. The diagnosis is made endoscopically; therefore, there is great variability in their assessment. Portal hypertensive gastropathy can range from a mosaic-like pattern resembling snakeskin mucosa to frankly bleeding petechial lesions. Portal hypertensive colopathy has been less well-described and is variably characterized (erythema, vascular lesions, petechiae). Treatment is challenging and results are inconsistent. Currently, available evidence does not support the use of beta-blockers for primary prevention. Further investigation of the pathogenesis, natural history, and treatment of these disorders is needed.

Abstract
Chronic hepatitis C (HCV) infection remains a major public health problem with many infected individuals worldwide. The revolutionary discovery of highly effective direct-acting antivirals (DAAs) makes chronic HCV infection a curable disease, even in patients with advanced liver disease. Liver function may improve shortly after initiation of antiviral therapy in patients on the waiting list and could even obviate the need for transplantation. However, whether these short term benefits also result in a favorable prognosis on the long-term remains to be seen and this fuels the discussion whether DAAs should be used prior to liver transplantation in all patients. Following liver transplantation, DAA treatment is also highly effective so that postponing antiviral treatment to the post-transplant setting may be better for certain patients. Furthermore, the discussion whether HCV positive organ donors should be used now viral eradication is achieved in almost all patients has regained interest.

Abstract
AIM To describe the pathophysiology, clinical presentation, natural history, and therapy of portal hypertensive gastropathy (PHG) based on a systematic literature review. METHODS Computerized search of the literature was performed via PubMed using the following medical subject headings or keywords: "portal" and "gastropathy"; or "portal" and "hypertensive"; or "congestive" and "gastropathy"; or "congestive" and "gastroenteropathy". The following criteria were applied for study inclusion: Publication in peer-reviewed journals, and publication since 1980. Articles were independently evaluated by each author and selected for inclusion by consensus after discussion based on the following criteria: Well-designed, prospective trials; recent studies; large study populations; and study emphasis on PHG. RESULTS PHG is diagnosed by characteristic endoscopic findings of small polygonal areas of variable erythema surrounded by a pale, reticular border in a mosaic pattern in the gastric fundus/body in a patient with cirrhotic or non-cirrhotic portal hypertension. Histologic findings include capillary and venule dilatation, congestion, and tortuosity, without vascular fibrin thrombi or inflammatory cells in gastric submucosa. PHG is differentiated from gastric antral vascular ectasia by a different endoscopic appearance. The etiology of PHG is inadequately understood. Portal hypertension is necessary but insufficient to develop PHG because many patients have portal hypertension without PHG. PHG increases in frequency with more severe portal hypertension, advanced liver disease, longer liver disease duration, presence of esophageal varices, and endoscopic variceal obliteration. PHG pathogenesis is related to a hyperdynamic circulation, induced by portal hypertension, characterized by increased intrahepatic resistance to flow, increased splanchnic flow, increased total gastric flow, and most likely decreased gastric mucosal flow. Gastric mucosa in PHG shows increased susceptibility to gastrotoxic chemicals and poor wound healing. Nitrous oxide, free radicals, tumor necrosis factor-alpha, and glucagon may contribute to PHG development. Acute and chronic gastrointestinal bleeding are the only clinical complications. Bleeding is typically mild-to-moderate. Endoscopic therapy is rarely useful because the bleeding is typically diffuse. Acute bleeding is primarily treated with octreotide, often with concomitant proton pump inhibitor therapy, or secondarily treated with vasopressin or terlipressin. Nonselective β-adrenergic receptor antagonists, particularly propranolol, are used to prevent bleeding after an acute episode or for chronic bleeding. Iron deficiency anemia from chronic bleeding may require iron replacement therapy. Transjugular-intrahepatic-portosystemic-shunt and liver transplantation are highly successful ultimate therapies because they reduce the underlying portal hypertension. CONCLUSION PHG is important to recognize in patients with cirrhotic or non-cirrhotic portal hypertension because it can cause acute or chronic GI bleeding that often requires pharmacologic therapy.

Abstract
There has long been evidence that hepatitis C can lead to persistent infection in a high proportion of infected individuals, and can progress to chronic liver disease, cirrhosis and hepatocellular carcinoma (HCC). The transition from acute to chronic hepatitis C is usually sub-clinical. Accurate studies of the time course for clearance of acute hepatitis C are difficult to carry out because of the silent onset of the acute disease. The likelihood of spontaneous HCV resolution is associated with several genetic factors, including IL28B inheritance and the DQB1*0301 allele of the major histocompatibility complex class II. Most data suggest that resolution in the acute phase without progression to chronic disease is not accompanied by significant disease, but minor histological lesions have been observed in anti-HCV positive, HCV RNA negative individuals. The risk of reinfection remains a possibility after clearance of acute hepatitis C. High rates of sexually-transmitted infection are being reported in HIV positive men who have sex with men (MSM). Chronic infection with HCV is the leading cause of end-stage liver disease, hepatocellular carcinoma (HCC) and liver related death in the Western world. The natural history of the chronic disease remains incompletely defined. It is generally a slowly progressive disease characterized by persistent hepatic inflammation, leading to the development of cirrhosis in approximately 10-20% of patients over 20-30 years of HCV infection. However, the published data indicate varying progression rates to cirrhosis. Overall, once cirrhosis has developed there is a 1-5% annual risk of HCC and a 3-6% annual risk of hepatic decompensation. Following an episode of decompensation the risk of death in the following year is between 15% and 20%. The high number of chronically infected individuals, the burden of disease, and the absence of a vaccine indicates that treatment will form part of the disease control but the impact, effectiveness and outcomes of treatment in various groups remain uncertain. Several studies and meta-analysis have concluded that eradication of HCV with antiviral therapy reduces the risk of HCC in patients with chronic hepatitis C, independent of fibrosis stage, but the risk is not eliminated.

Abstract
Background The timely publication of findings in peer-reviewed journals is a primary goal of clinical research. In clinical trials, the processes leading to publication can be complex from choice and prioritization of analytic topics through to journal submission and revisions. As little literature exists on the publication process for multicenter trials, we describe the development, implementation, and effectiveness of such a process in a multicenter trial. Methods The Hepatitis C Antiviral Long-Term Treatment against Cirrhosis (HALT-C) trial included a data coordinating center (DCC) and clinical centers that recruited and followed more than 1,000 patients. Publication guidelines were approved by the steering committee, and the publications committee monitored the publication process from selection of topics to publication. Results A total of 73 manuscripts were published in 23 peer-reviewed journals. When manuscripts were closely tracked, the median time for analyses and drafting of manuscripts was 8 months. The median time for data analyses was 5 months and the median time for manuscript drafting was 3 months. The median time for publications committee review, submission, and journal acceptance was 7 months, and the median time from analytic start to journal acceptance was 18 months. Conclusions Effective publication guidelines must be comprehensive, implemented early in a trial, and require active management by study investigators. Successful collaboration, such as in the HALT-C trial, can serve as a model for others involved in multidisciplinary and multicenter research programs. Trial registration The HALT-C Trial was registered with clinicaltrials.gov (NCT00006164).
