Abstract
The first clinical guidelines on hepatic encephalopathy were published in 2009. Almost 14 years since that first publication, numerous advances in the field of diagnosis, treatment, and special condition care have been made. Therefore, as an initiative of the Asociación Mexicana de Gastroenterología A.C., we present a current view of those aspects. The manuscript described herein was formulated by 24 experts that participated in six working groups, analyzing, discussing, and summarizing the following topics: Definition of hepatic encephalopathy; recommended classifications; epidemiologic panorama, worldwide and in Mexico; diagnostic tools; conditions that merit a differential diagnosis; treatment; and primary and secondary prophylaxis. Likewise, these guidelines emphasize the management of certain special conditions, such as hepatic encephalopathy in acute liver failure and acute-on-chronic liver failure, as well as specific care in patients with hepatic encephalopathy, such as the use of medications and types of sedation, describing those that are permitted or recommended, and those that are not.

Abstract
Chronic viral hepatitis is a significant health problem throughout the world, which already represents high annual mortality. By 2040, chronic viral hepatitis due to virus B and virus C and their complications cirrhosis and hepatocellular carcinoma will be more deadly than malaria, vitellogenesis-inhibiting hormone, and tuberculosis altogether. In this review, we analyze the global impact of chronic viral hepatitis with a focus on the most vulnerable groups, the goals set by the World Health Organization for the year 2030, and the key points to achieve them, such as timely access to antiviral treatment of direct-acting antiviral, which represents the key to achieving hepatitis C virus elimination. Likewise, we review the strategies to prevent transmission and achieve control of hepatitis B virus. Finally, we address the impact that the coronavirus disease 2019 pandemic has had on implementing elimination strategies and the advantages of implementing telemedicine programs.

Primary Prophylaxis to Prevent the Development of Hepatic Encephalopathy in Cirrhotic Patients with Acute Variceal Bleeding. Can J Gastroenterol Hepatol 2018; 2018:3015891. [PMID: 30079329 PMCID: PMC6069577 DOI: 10.1155/2018/3015891] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/07/2018] [Revised: 05/25/2018] [Accepted: 05/31/2018] [Indexed: 12/25/2022] [Imported: 08/29/2023] Open
Abstract
BACKGROUND AND AIM Variceal bleeding is the second most important precipitating factor related to the development of episodic hepatic encephalopathy; but to date there are no recommendations to prevent this complication. The aim of this study was to compare if primary prophylaxis with lactulose or L-ornithine L-aspartate or rifaximin, in cirrhotic patients with variceal bleeding, is better than placebo for avoiding the development of hepatic encephalopathy. METHODS A randomized, double-blind, placebo-controlled clinical trial (ClinicalTrials.gov identifier: NCT02158182) which included cirrhotic patients with variceal bleeding, without minimal or clinical hepatic encephalopathy at admission. FINDINGS 87 patients were randomized to one of four groups. The basal characteristics were similar between groups. Comparatively with placebo, the frequency with regard to the development of hepatic encephalopathy was as follows: lactulose (54.5% versus 27.3%; OR = 0.3, 95% CI 0.09-1.0; P = 0.06); L-ornithine L-aspartate (54.5% versus 22.7%, OR = 0.2, 95% CI 0.06-0.88; P = 0.03); rifaximin (54.5% versus 23.8%; OR = 0.3, 95% CI 0.07-0.9; P = 0.04). There was no significant difference between the three groups receiving any antiammonium drug (P = 0.94). In the group receiving lactulose, 59.1% had diarrhea, and 45.5% had abdominal discomfort, bloating, and flatulence. Two patients (10%) treated with lactulose and a patient (4.5%) in the placebo group developed spontaneous bacterial peritonitis due to E. coli; one of them died due to recurrent variceal bleeding. There were no other adverse effects. CONCLUSIONS Antiammonium drugs, particularly L-ornithine L-aspartate and rifaximin, proved to be effective in preventing the development of hepatic encephalopathy in those cirrhotic patients with variceal bleeding.

World J Hepatol 2017; 9:263-269. [PMID: 28261383 PMCID: PMC5316846 DOI: 10.4254/wjh.v9.i5.263] [Citation(s) in RCA: 18] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/13/2016] [Revised: 09/12/2016] [Accepted: 12/09/2016] [Indexed: 02/06/2023] [Imported: 08/29/2023] Open
Abstract
AIM To verify how malnutrition is related to health-related quality of life (HRQL) impairment in patients with cirrhosis.
METHODS Data was retrospectively abstracted from medical records and obtained by direct interview. We included patients with cirrhosis from any etiology, evaluated at the Liver Clinic from Gastroenterology Department in a tertiary healthcare center, from June 2014 to June 2016. Child-Pugh score, data about complications, and demographic, clinical and anthropometric characteristics of patients were obtained. Nutritional status was evaluated by the Subjective Global Assessment (SGA). HRQL was evaluated through the Chronic Liver Disease Questionnaire. Patients were requested to assess their global HRQL with the following code: 0 = impairment of HRQL, when it was compared with other healthy subjects; 1 = good HRQL, if it was similar to the quality of life of other healthy subjects. To compare the primary outcome between malnourished and well-nourished groups, the χ2 test, Fisher’s exact test or Student’s t-test were used, based on the variable type. Associations between predictor variables and deterioration of HRQL were determined by calculating the hazard ratio and 95% confidence interval using Cox proportional hazards regression.
RESULTS A total of 127 patients with cirrhosis were included, and the mean age was 54.1 ± 12.3 years-old. According to Child-Pugh scoring, 25 (19.7%) were classified as A (compensated), 76 (59.8%) as B, and 26 (20.5%) as C (B/C = decompensated). According to SGA, 58 (45.7%) patients were classified as well-nourished. Sixty-nine patients identified HRQL as good, and 76 patients (59.8%) perceived impairment of their HRQL. Multivariate analysis to determine associations between predictor variables and self-perception of an impairment of HRQL found strong association with malnutrition (P < 0.0001). The most important impaired characteristics in malnourished patients were: Presence of body pain, dyspnea on exertion with daily activities, decreased appetite, generalized weakness, trouble lifting or carrying heavy objects, and decreased level of energy (P < 0.0001).
CONCLUSION Malnutrition is a key factor related to impairment of HRQL in patients with cirrhosis.

Abstract
Non-alcoholic fatty liver disease (NAFLD) is a major health care problem and represents the hepatic expression of the metabolic syndrome. NAFLD is classified as non-alcoholic fatty liver (NAFL) or simple steatosis, and non-alcoholic steatohepatitis (NASH). NASH is characterized by the presence of steatosis and inflammation with or without fibrosis. The physiopathology of NAFL and NASH and their progression to cirrhosis involve several parallel and interrelated mechanisms, such as, insulin resistance (IR), lipotoxicity, inflammation, oxidative stress, and recently the gut-liver axis interaction has been described. Incretin-based therapies could play a role in the treatment of NAFLD. Glucagon-like peptide-1 (GLP-1) is an intestinal mucosa-derived hormone which is secreted into the bloodstream in response to nutrient ingestion; it favors glucose-stimulated insulin secretion, inhibition of postprandial glucagon secretion and delayed gastric emptying. It also promotes weight loss and is involved in lipid metabolism. Once secreted, GLP-1 is quickly degraded by dipeptidyl peptidase-4 (DPP-4). Therefore, DPP-4 inhibitors are able to extend the activity of GLP-1. Currently, GLP-1 agonists and DPP-4 inhibitors represent attractive options for the treatment of NAFLD and NASH. The modulation of lipid and glucose metabolism through nuclear receptors, such as the farsenoid X receptor, also constitutes an attractive therapeutic target. Obeticholic acid is a potent activator of the farnesoid X nuclear receptor and reduces liver fat content and fibrosis in animal models. Ursodeoxycholic acid (UDCA) is a hydrophilic bile acid with immunomodulatory, anti-inflammatory, antiapoptotic, antioxidant and anti-fibrotic properties. UDCA can improve IR and modulate lipid metabolism through its interaction with nuclear receptors such as, TGR5, farnesoid X receptor-α, or the small heterodimeric partner. Finally, pharmacologic modulation of the gut microbiota could have a role in the therapy of NAFLD and NASH. Probiotics prevent bacterial translocation and epithelial invasion, inhibit mucosal adherence by bacteria, and stimulate host immunity. In animal models, probiotics prevent obesity, decrease transaminase levels, and improve IR and liver histology in NASH.

Mean platelet volume as a novel predictor of systemic inflammatory response in cirrhotic patients with culture-negative neutrocytic ascites. World J Hepatol 2015; 7:1001-1006. [PMID: 25954482 PMCID: PMC4419093 DOI: 10.4254/wjh.v7.i7.1001] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/14/2015] [Revised: 02/21/2015] [Accepted: 04/07/2015] [Indexed: 02/06/2023] [Imported: 08/29/2023] Open
Abstract
AIM: To identify a mean platelet volume (MPV) cutoff value which should be able to predict the presence of bacterial infection.
METHODS: An observational, analytic, retrospective study. We evaluated medical records of cirrhotic patients who were hospitalized from January 2012 to January 2014 at the Gastroenterology Department of “Hospital General de México Dr. Eduardo Liceaga”, we included 51 cirrhotic patients with ascites fluid infection (AFI), and 50 non-infected cirrhotic patients as control group. Receiver operator characteristic curves were used to identify the best cutoff value of several parameters from hematic cytometry, including MPV, to predict the presence of ascites fluid infection.
RESULTS: Of the 51 cases with AFI, 48 patients (94.1%) had culture-negative neutrocytic ascites (CNNA), 2 (3.9%) had bacterial ascites, and one (2%) had spontaneous bacterial peritonitis. Infected patients had greater count of leucocytes and polymorphonuclear cells, greater levels of MPV and cardiac frequency (P < 0.0001), and lower mean arterial pressure compared with non-infected patients (P = 0.009). Leucocytes, polymorphonuclear count, MPV and cardiac frequency resulted to be good or very good predictive variables of presence of AFI in cirrhotic patients (area under the receiving operating characteristic > 0.80). A cutoff MPV value of 8.3 fl was the best to discriminate between cirrhotic patients with AFI and those without infection.
CONCLUSION: Our results support that MPV can be an useful predictor of systemic inflammatory response syndrome in cirrhotic patients with AFI, particularly CNNA.

Abstract
AIM: To evaluate the impact of metadoxine (MTD) on the 3- and 6-mo survival of patients with severe alcoholic hepatitis (AH).
METHODS: This study was an open-label clinical trial, performed at the “Hospital General de México, Dr. Eduardo Liceaga”. We randomized 135 patients who met the criteria for severe AH into the following groups: 35 patients received prednisone (PDN) 40 mg/d, 35 patients received PDN+MTD 500 mg three times daily, 33 patients received pentoxifylline (PTX) 400 mg three times daily, and 32 patients received PTX+MTD 500 mg three times daily. The duration of the treatment for all of the groups was 30 d.
RESULTS: In the groups treated with the MTD, the survival rate was higher at 3 mo (PTX+MTD 59.4% vs PTX 33.3%, P = 0.04; PDN+MTD 68.6% vs PDN 20%, P = 0.0001) and at 6 mo (PTX+MTD 50% vs PTX 18.2%, P = 0.01; PDN+MTD 48.6% vs PDN 20%, P = 0.003) than in the groups not treated with MTD. A relapse in alcohol intake was the primary independent factor predicting mortality at 6 mo. The patients receiving MTD maintained greater abstinence than those who did not receive it (74.5% vs 59.4%, P = 0.02).
CONCLUSION: MTD improves the 3- and 6-mo survival rates in patients with severe AH. Alcohol abstinence is a key factor for survival in these patients. The patients who received the combination therapy with MTD were more likely to maintain abstinence than those who received monotherapy with either PDN or PTX.

Abstract
BACKGROUND There are many models to predict survival in patients with alcoholic hepatitis (AH). The most commonly used are the modified Maddrey's index, the Glasgow scale and the Model for End stage Liver Disease (MELD). OBJECTIVE To evaluate three prognostic scales ability to predict early mortality (first 30 days) in patients with AH. METHODS We retrospectively reviewed the database of hospitalized patients with AH during a 3-years period. Seventy one patients were included. We calculated the modified Maddrey's index, the Glasgow scale and the MELD scores. We evaluated if the scales predicted early (30-day) mortality. For each scale we determined sensitivity, specificity, positive and negative values (PPV and NPV) and likelihood value of each scale. RESULTS For modified Maddrey's index, the values obtained were sensitivity 98.8%, specificity 11.7%, PPV 61.6%, NPV 87.5% and likelihood ratio 1.12. For Glasgow scale corresponding values were sensitivity 98.8%, specificity 61.7%, PPV 78.7%, NPV 97.4% and likelihood ratio 2.64. For the MELD scale sensitivity 98.8%, specificity 0.1%, PPV 59%, NPV 50% and likelihood ratio 1. CONCLUSIONS The three scales were very sensitive. Glasgow's scale was the most specific and, maybe, the most exact test.

Abstract
BACKGROUND Acute renal failure (ARF) worsens the prognosis of patients with alcoholic hepatitis (HA). Other factors like the amount of alcohol intake, upper gastrointestinal bleeding (UGB) or hepatic encephalopathy (HE) are not considered at present in any prognostic index. OBJECTIVE To evaluate if the amount of alcohol intake, development of UGB, ARF and/or HE are associated with high mortality in patients with AH. METHODS Consecutive patients with diagnosis of AH were included. Demographic, laboratory data, complications and mortality were registered. A comparison was performed between survivors and non-survivors. RESULTS Seventy-one patients were included. Median amount of alcohol consumption was 187.7 g/day, and was superior in men (190.8 vs. 169 g/day, p = 0.02) and in patients who developed ARF (219.6 vs. 144.1 g/day, p = 0.001). Maddrey s index was higher in patients who died than those who survive (111.4 vs. 52.9, p = 0.02). No differences between groups were recorded regarding Glasgow and MELD scales. ARF was the only one complication related with higher risk of death (RR = 6.7, p = 0.02). Isolated UGB and HE were non-significantly associated with mortality, but combination of two or three complications was highly significantly associated with mortality risk: ARF and HE (OR = 8.9, p = 0.001), HE and UGB (OR = 6.7, p = 0.01) and ARF + UGB + HE (OR = 10, p = 0.001). CONCLUSION The amount of alcohol intake is associated with development of ARF. ARF was the most significant risk factor associated with mortality. The presence of two or three complications increases the mortality risk significantly. Key words: acute renal failure, hepatic encephalopathy, risk factors, mortality, alcoholic hepatitis, Mexico.
