Helicobacter pylori is a gram-negative, spiral-shaped bacterium that inhabits the gastric environment of 60.3% of the global population. Though most individuals infected with the bacterium remain asymptomatic, it is known that this infection plays a pivotal role in the development of diseases such as chronic gastritis, peptic ulcer, gastric cancer and gastric MALT lymphoma. Hence, eradication of H. pylori is associated with the potential prevention of many gastric and extra gastric diseases, such as gastric cancer.Arch Gastroenterol Res, 2021, Volume 2, Issue 3, p75-78 | DOI: 10.33696/Gastroenterology.2.031
Until the early sixties, the concept prevailed that alcoholic liver disease (ALD), also termed alcohol-related liver disease (ARLD), results from malnutrition commonly observed among individuals consuming chronically high amounts of alcohol rather than being causally related to the use of alcoholic beverages. However, the malnutrition concept became a matter of debate because of the clinical observation that humans, even on a normal diet and without signs of underweight or malnutritionArch Gastroenterol Res, 2021, Volume 2, Issue 1, p9-25 | DOI: 10.33696/Gastroenterology.2.022
Multidisciplinary treatment is widely applied for hepatocellular carcinoma (HCC) using liver resection/ transplantation, local ablation therapy, transarterial chemoembolization (TACE), and systemic therapy. Systemic therapy is recommended and can provide a modest prognosis for HCC in Barcelona Clinic Liver Cancer (BCLC) staging C.Arch Gastroenterol Res, 2020, Volume 1, Issue 4, p117-123 | DOI: 10.33696/Gastroenterology.1.020
Are We Close to Achieving a HBV Cure? Risk for Hepatocellular Carcinoma Persists Despite Long-term HBV Suppression: An Update on Our Experience
Since the discovery of the hepatitis B virus (HBV) by Blumberg et al., great progress has been made in understanding the pathogenesis of the virus and its role in hepatocellular carcinoma (HCC). It is estimated that hepatitis B is responsible for about 50% of the HCC cases worldwide. Because of geographic variations in HBV incidence, the burden of HBV-related HCC (HBV-HCC) is highest in endemic areas such as Asian-Pacific and sub- Saharan Africa and lowest in the United States and the West. The hepatitis B vaccines, developed in the 1980s, transformed the evolution of hepatitis B in the modern era. This was followed by high effective anti-viral that reduced HBV infections and HBV-HCC.Arch Gastroenterol Res, 2020, Volume 1, Issue 4, p105-110 | DOI: 10.33696/Gastroenterology.1.018
Hepatitis B virus (HBV) chronically infects more than 250 million individuals worldwide and is responsible for more than 800,000 deaths per year by promoting end-stage liver diseases, among which decompensated cirrhosis and hepatocellular carcinoma (HCC) (WHO, July 2020) are prominent. Studies performed in chimpanzees or in animalversion of HBV (woodchuck HBV: WHBV) highlighted the lack of immune responses against the virus upon primary infection. Thus, HBV has been described as a “stealth” virus (i.e. a virus that does not modify/induce immune response in the cell). However, a growing number of studies describe that HBV is able to rapidly and efficiently counteract the innate immune response in a large variety of cells (hepatocytes, macrophages, Natural Killer cell…). Hereby, we focus on the role of macrophages (Mφ) during HBV infection.Arch Gastroenterol Res, 2020, Volume 1, Issue 4, p89-94 | DOI: 10.33696/Gastroenterology.1.016
Gastric cancer (GC), also known as stomach cancer, is a worldwide health problem. Anatomically, it can occur from the gastroesophageal junction to distal portions of the stomach. Considering both sexes, worldwide, it is the 5th most common neoplasm (5.7%) and the 3rd cause of mortality among malignancies, leading to approximately 782,000 deaths in 2018. The incidence varies geographically but 50% of new cases are diagnosed in developed countries. High incidence is observed in Asia, Latin America, and in the central and eastern parts of Europe. There are several ways to classify GC, but the most used is Lauren’s Classification, which proposes two main histological groups: intestinal and diffuse. This classification is important because there are marked etiological, pathological, and epidemiological differences between the subgroups, guiding the clinical approach for each patient.Arch Gastroenterol Res, 2020, Volume 1, Issue 2, p34-39 | DOI: 10.33696/Gastroenterology.1.008
