IFN based treatments were the standard therapy, against HCV infection waiting for pending authorization to place the direct acting antivirals on the market. These new direct acting antivirals generic conferred good effectiveness and safety for infected patients. The aim of this study was to characterize the treatment response and tolerance of new generics of DAAs in patients infected with hepatitis C virus. The study was conducted at the gastroenterology I department of the military hospital Mohamed V in Rabat since December 2015. We include all patients infected with HCV: naïf relapsing or non-responsive profiles, all genotypes combined, cirrhotic or not. They all received treatment with the new Moroccan generic of direct acting antivirals. Virological response as well as clinical and biochemical tolerances were achieved. 77 patients with viral hepatitis C were included in the study. The average age of the patients was 61 ± 11 years old. A slight predominance of women noted in 52.8% of cases. Genotype 1 was predominant in 74% of cases. Half of our patients were cirrhotic. The sustained virogical response SVR was of the order of 96.2%. The treatment generally well tolerated in all our patients. The generic of direct acting antivirals promises treatments with shorter treatment times, much higher cure rates, and fewer side effects. Viral eradication leads stabilization or regression of fibrosis.","PeriodicalId":93828,"journal":{"name":"World journal of gastroenterology, hepatology and endoscopy","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77561261","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In many cases, the symptomatic GERD is linked to a normal upper gastrointestinal endoscopy and new endoscopic techniques to identify the abnormalities are need. The high-definition digestive endoscopy coupled with narrow band imaging (NBI) could achieve a more detailed mucosal evaluation, allowing the identification of distal esophageal microerosions. Objectives: To validate the presence of distal esophageal microerosions as found in high-definition endoscopy with NBI and the associative pHmetry, histological, immunohistochemical findings of tissue specimens obtained from esophageal biopsies of patients with typical symptoms of GERD. Methods: A total of 70 participants were enrolled in a prospective, descriptive and cross-sectional study from a gastroenterology outpatient clinic. Endoscopic evaluation was sequentially performed after the pHmetry. Esophageal mucosal biopsies were obtained to perform the histological and immunohistochemical analysis. Results: From 70 participants, 30/70 (42.9%) showed mucosal microerosions. Both, pHmetry and histologic score for esophageal mucosa did not showed difference between participants with or without endoscopic microerosions. The quantitative cellular evaluation by immunohistochemistry of the esophageal mucosa was performed in 56/70 (80%) participants, which 27/56 (48.21%) showed microerosions. Also, no difference occurred between participants with or without endoscopic microerosions regarding total number of cells immunolabelled and number of cells per tissue area. Conclusions: No difference occurred between the groups of participants with typical symptoms of GERD and with or without esophageal microerosions screened by high-definition digestive endoscopy coupled with NBI regarding pHmetric, histological and immunohistochemical analysis.","PeriodicalId":93828,"journal":{"name":"World journal of gastroenterology, hepatology and endoscopy","volume":"57 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79363611","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Over the passage of time the severity of the variceal bleeding and complications related to it have significantly reduced. This reduction in complications is due to improvement in the clinical management, universal availability of vasopressor drugs, improved endoscopic therapies as well as due to availability of definitive treatment options such as trans jugular intra hepatic porto systemic shunt (TIPS) and liver transplantation. About 10-20% patients presenting with AVB do not respond to the initial management (defined as failure to control bleeding within 48 hrs) and develop re bleeding within 5 days of starting the therapy (after initial control of bleeding), these patients can be defined to have refractory variceal bleeding (Figure 2).","PeriodicalId":93828,"journal":{"name":"World journal of gastroenterology, hepatology and endoscopy","volume":"24 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85070233","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We investigate the LAL activity (LAL-A) in patients with hepatic dysfunction and/or dyslipidemia and determine the associated clinical and biochemical parameters. Methods: This prospective, cross-sectional study included 360 children (3 months -18 years; 40 control, and 320 screening patients). Demographic data, major clinical and laboratory findings, LAL-A and possible biomarkers were evaluated. Screening group was divided into two: LAL-A<0.6 nmol/ml/h (Group1); LAL-A ≥ 0.6 nmol/ml/h (Group 2). LAL-A predictive model was evaluated using logistic regression. Results: The mean LAL-A in the screening group (1.43 ± 2.05 (0.03-16.8) nmol/ml/h) was significantly reduced compare to controls (p < 0.001). No LAL deficiency was detected. There was a negative correlation between LAL-A and low-density lipoprotein cholesterol, triglyceride, and alanine aminotransferase (ALT) levels. LAL-A in patients with chronic fatigue (p = 0.002), hepatomegaly (p = 0.013) and splenomegaly (p = 0.001) were significantly lower compare to those without. The median thiobarbituric acid reactive substances, myeloperoxidase, chitotriosidase, hs-CRP, Citokeratin levels in Group 1 were higher compare to the controls (p < 0.005). Conclusions: LAL-A was reduced in paediatric patients with dyslipidemia and/or elevated transaminase. Our final multivariable predictive model for reduced LAL-A included: ALT, triglyceride, and hepatomegaly. *Correspondence to: Sema Kalkan Uçar, Department of Pediatrics, Division of Metabolism and Nutrition, Ege University Medical Faculty, Bornova, Izmir, Turkey, Tel: 90.232.390.1037, E-mail: semakalkan@hotmail.com","PeriodicalId":93828,"journal":{"name":"World journal of gastroenterology, hepatology and endoscopy","volume":"50 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83675407","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Symptoms are often severe and require additional therapeutic intervention besides a GFD. RCD can be classified as type 1 which usually improves after treatment with a combination of aggressive nutritional support, adherence to a GFD, and alternative pharmacological therapies. By contrast, clinical response to alternative therapies in RCD type 2 is less certain and the prognosis is poor.
