Helicobacter pylori, Epstein-Barr virus and human papillomavirus are three pathogens associated with various human cancers. This study aimed to investigate the role of these pathogens in gastric cancer in Moroccan population. For this, a retrospective study has been conducted on participants attending the gastroenterology department of Hassan II University Hospital of Fez.

This study aimed to investigate the combination of the four regions of Helicobacter pylori vacA with cagA, cagE, dupA genes and cagA-EPIYA motifs to identify the most likely combination that could be used as a disease determinant marker in the Moroccan population. A total of 838 H. pylori-positive samples were obtained from consenting patients, that were previously analyzed by PCR to characterize vacA-s, -m, and -i regions; cagE status; and cagA 3' region polymorphism, were used to characterize vacA-d region and to determine dupA gene status.

Unlabelled: The transarterial chemoembolization (TACE) is a firstline therapeutic option for advanced hepatocellular carcinoma (HCC). Their indications are clearly defined by learned societies but the challenge is to determine the optimal number of TACE sessions that will benefit patients before switching to other therapies. For this reason, the Assessment for Retreatment with Transarterial chemoembolization (ART) score has been developed.

SARS-CoV-2 infection is a major concern and a new threat to immunocompromised patients. Patients with chronic inflammatory bowel diseases (IBDs) are at increased risk of infections, in particular when they have active disease and are on immunosuppressive treatment. The purpose of this study was to assess the clinical, biological and radiological features of three patients with COVID-19 associated with chronic IBD as well as their management and outcomes.

Introduction: The Cancer Genome Atlas (TCGA) project and Asian Cancer Research Group (ACRG) recently categorized gastric cancer into molecular subtypes. Nevertheless, these classification systems require high cost and sophisticated molecular technologies, preventing their widespread use in the clinic. This study is aimed to generating molecular subtypes of gastric cancer using techniques available in routine diagnostic practice in a series of Moroccan gastric cancer patients.

Helicobacter pylori infection is the most important etiological factor in gastroduodenal diseases development. Its evolution is influenced by several factors, including bacterial virulence genes such as cagA and cagE. This work aimed to evaluate the predictive value of cagE alone and in combination with cagA and CagA-EPIYA-C motifs number as a marker of the infection evolution.

To investigate correlations between microsatellite instability (MSI) and the phenotype, clinicopathological features, and overall survival (OS) in Moroccan gastric cancer (GC) patients. We evaluated the mutation frequency of 22 MSI-target genes in MSI-positive tumors. MSI evaluation were performed for 97 gastric tumors by multiplex polymerase chain reaction (PCR) using a panel of five quasimonomorphic mononucleotide repeat markers (NR27, NR21, NR24, BAT25, and BAT26).

IgG4-Related disease (IgG4-RD), formerly known as IgG4-related autoimmune polyexocrinopathy, is a new condition including Plasminogen Activator Inhibitor-1 (PAI-1). It can affect different organs (central nervous system, salivary glands, thyroid, lungs, pancreas, bile ducts, liver, digestive tract, kidneys, prostate, etc.) with symptoms depending on the organ that is affected.

Helicobacter pylori infection induces inflammation of the gastric mucosa, which may progress to precancerous lesions and gastric cancer. The gastric histo-pathological damages may be associated with some virulence genes of the bacterium, notably vacA and cagA genes. To establish correlations between these genes and the lesions, biopsies from 1303 adults consenting patients that were previously analyzed by PCR to characterize vacA-s vacA-m, vacA-i regions and cagA 3' region polymorphism, were used.

Background: Alpha-fetoprotein (AFP) is a serum tumor marker used in the past for surveillance and screening of hepatocellular carcinoma (HCC) in patients with cirrhosis. Its prognostic value is still debated in the literature. The aim of this study was to evaluate the prognostic impact of the AFP rate at diagnosis on the overall survival of patients with a small HCC (<3cm) in patients with cirrhosis.

Pathologic features depending on tumor response to preoperative chemoradiotherapy are important to determine the outcomes in patients with rectal cancer. Evaluating the potential predictive roles of biomarker expression and their prognostic impact is a promising challenge. We reported here the immunohistochemical staining of a panel marker of mismatch repair protein (MMR), Ki67, HER-2, and p53.

Background: Although its incidence has decreased over the last 20 years, gastric adenocarcinoma remains frequent (1,033,701 new cases worldwide per year, Globocan 2018). Its prognosis is still poor, with overall survival rates of 10 to 25% despite improvement in surgical and perioperative treatment. In Morocco, we do not have data on survival and predictors of mortality in our population, the present study aims to describe the epidemiological and clinicopathological features of gastric adenocarcinoma and the survival rate.

Introduction: Viral hepatitis represents a serious public health problem in the world especially in the Maghreb where the prevalence of the 5 viruses A, B, C, D, and E remains high and varies from one Maghreb country to another, there is few published studies on these infections in our Maghreb countries.

Method Of Study: Our work is a review of the literature about prevalence, the most common mode of transmission, and the most exposed population for these viruses in the Maghreb countries through published studies between 2011 and 2017.

Result: It has been found that the Maghreb countries are endemic for the five viruses with variable prevalence from one country to another, with sometimes heterogeneous data in the same country.

Introduction: The biliobronchial fistula of hydatic origin is a rare complication and the left localization is exceptional.

Observation: We report the case of a 26-year-old patient from the rural area who was referred to us for treatment of biliptysis. The thoracic and abdominal computed tomography diagnosed a left biliobronchial fistula was.

Article Synopsis
  • The study examines the relationship between H. pylori strains and gastric diseases in Moroccan patients, focusing on the EPIYA motifs in the cagA gene.
  • The research involved 1353 patients, revealing a 61.1% infection rate and indicating that 68.9% carried the cagA gene, primarily the "Western CagA" type with a notable presence of EPIYA-ABC motifs.
  • Results show that having two EPIYA-C motifs significantly increases the risk of developing gastric cancer compared to strains without these motifs, suggesting their potential as a predictive marker for cancer risk.

Introduction: The bronchial biliary fistula surgery is a major one, always going with a higher rate of complication especially in case of bile duct obstruction. The aim of this study is to find out the contribution of endoscopic sphincterotomy while reporting the results of surgical treatment of bronchial biliary fistulae by exclusive thoracotomy.

Methods: This was a retrospective study, which took place in the Department of Thoracic Surgery, University Hospital Hassan II, from January 2009 to March 2016.

Helicobacter pylori (H. pylori) infection induces inflammation of the gastric mucosa, which may progress to precancerous lesions leading to gastric cancer. Pathological determinism is associated to some virulence genes of the bacterium, notably the vacA and cagA genes.

Lynch syndrome or hereditary nonpolyposis colorectal cancer (HNPCC) is the most common form of hereditary colorectal cancers. It increases cancer susceptibility, the risk of colorectal cancer in first-degree, endometrial cancer in women, and to a lesser extent, other cancers (ovarian, small bowel, stomach, urinary tract and hepatobiliary). Thus, the cumulative risk of developing colorectal cancer or endometrial cancer at the age of 80 years rises to 20 and 40% respectively.

Objective: The aim of this study was to assess and compare the efficacy and safety of sequential treatment with standard triple therapies in a located population in Morocco.

Methods: Consecutive H. pylori-positive patients with endoscopy-proven ulcer or non ulcer dyspepsia were prospectively randomized in the trial into one of three groups: AM and AC group were administered a tri-therapy for 7 days including PPI + amoxicillin + metronidazole (AM group)/clarithromycin (AC group) and SQ group was administered a sequential regimen consisting of PPI + amoxicillin for 5 days followed by PPI + clarithromycin + metronidazole for the remaining 5 days.
