Section of Gastroenterology
Background: In dyspeptic patients with Helicobacter pylori contributes to non-alcoholic fatty liver disease. However, little evidence available from Pakistan.
Objective: The study aims to determine the frequency and risk factors of non-alcoholic fatty liver disease in dyspeptic patients with Helicobacter pylori.
Methods: This cross-sectional study was conducted between 22 November 2016 and 30 June 2018. Adults of age between 18 and 90 years who attended the out-patient department due to abdominal discomfort, pain, fullness, and bloating who underwent upper gastrointestinal tract endoscopy were enrolled after taking informed consent.

Background The aim was to investigate the reinfection rate of H. pylori during a follow-up period of 12 months in adults who had undergone eradication therapy. Methods One hundred-twenty patients; 116 with gastritis, 3 with duodenal ulcer and 1 gastric ulcer, were studied. Their mean age was 41 ± 13 years (range 18–77) and male: female ratio of 2:1. H. pylori were cultured and antibiotic sensitivity was determined by Epsilometer test (E-test) for clarithromycin (CLR) and amoxicillin (AMX). Primers of urease C gene of H. pylori and Sau-3 and Hha I restriction enzymes were used for polymerase chain reaction-restriction fragment …

Journal of Mind and Medical Sciences
Acute upper gastrointestinal lesions have a multifactorial etiology but, regardless of the cause, they are related to mucosal barrier destruction. Since Helicobacter pylori induces a superficial chronic gastritis with the infiltration of neutrophils in the mucosa, it was speculated that Helicobacter pylori infection could also cause bleeding lesions. The diagnosis, the proper treatment and the revaluation of its effectiveness actually represent the prophylaxis of some diseases such as peptic ulcer, gastric lymphoma or mucosa-associated lymphoid tissue (MALT) and gastric cancer. These diseases and their severe complications are life-threatening for the patient. Periodic renewal of the treatment and knowing the real …

Section of Gastroenterology
BACKGROUND/AIM: Helicobacter pylori is a Gram-negative bacteria, which is associated with development of gastroduodenal diseases. The prevalence of H. pylori and the virulence markers cytotoxin-associated gene A and E (cagA, cagE) and vacuolating-associated cytotoxin gene (vacA) alleles varies in different parts of the world. H. pylori virulence markers cagA, cagE, and vacA alleles in local and Afghan nationals with H. pylori-associated gastroduodenal diseases were studied.
PATIENTS AND METHODS:Two hundred and ten patients with upper gastrointestinal symptoms and positive for H. pylori by the urease test and histology were included. One hundred and nineteen were local nationals and 91 were Afghans. …

Section of Gastroenterology
Plants used in popular diet were studied for anti-Helicobacter pylori activity and their effect on the expression of interleukin-8 (IL-8) from H. pylori infected gastric epithelial cells. Extracts were prepared of Allium sativum (A. sativum), Cuminum cyminum (C. cyminum),Piper nigrum (P. nigrum) and their mix in two different dilutions. AGS cell line and H. pyloristrains were used for co-culture experiments. Extracts bactericidal activity was determined by a viable colony count. ELISA (Enzyme linked immunosorbent assay) was used to determine IL-8 expression. DNA extracted from bacterial cells was used for polymerase chain reaction (PCR) …

This study aims to determine primary Helicobacter pylori resistance and its effect on eradication of the organism. Ninety-two Patients with dyspeptic symptoms were enrolled. H. pylori was cultured and antibiotic sensitivity was determined by the Epsilometer test (Etest) for clarithromycin (CLR), amoxicillin (AMX) and metronidazole (MTR). 23S ribosomal RNA (rRNA) point mutations associated with clarithromycin resistance were also detected. Patients were treated with omeprazole (40 mg daily), CLR (500 mg) and AMX (1g twice a day) for 14 days. A (14)C-urea breath test ((14)C-UBT) was repeated four weeks after completion of treatment to confirm eradication. Triple therapy failure was seen …

Department of Medicine
Clinical diseases that follow Helicobacter pylori infection are associated with expression of the cagA gene, a part of cytotoxin-associated gene pathogenicity island (cag-PAI). This study aims to determined whether or not the presence of cagA is associated with the presence of complete cag-PAI and to evaluate inflammatory changes associated with the five loci in the cag-PAI of H. pylori comprising cagA, cagA promoter region (cagAP), cagE, cagT and the left end of the cagA gene (LEC). H. pylori isolates were obtained from patients with dyspeptic symptoms. Clinical strains of H. pylori were screened by the polymerase chain reaction (PCR) for …

Section of Gastroenterology
Objective:
To determine the frequency of peptic ulcer disease in patients on nonsteroidal anti-inflammatory drugs (NSAID).
Methods:
Record of eight hundred and twenty consecutive patients undergoing upper gastrointestinal (GI) endoscopy; from January 1998 to December 2000 were reviewed. The endoscopic diagnosis varied from gastritis, peptic ulcer to duodenitis. The use of NSAID was documented by reviewing medical records of patients with peptic ulcer.
Results:
Peptic ulcers were found in 43% (353/820) patients. NSAID associated peptic ulcers were identified in 14.7% (52/353) patients. Diclofenac and aspirin were most common NSAIDs associated with peptic ulcers in 32.7% (17/52) and 30.7% (16/52) patients, …

Section of Gastroenterology
Background
The aim of this study was to determine the effect of commonly self-prescribed proton pump inhibitors (PPI) on the results of rapid urease test and histology for the diagnosis of H. pylori infection.
Methods
One hundred-nine consecutive patients with dyspeptic symptoms attending the endoscopy suite were enrolled in this study. Antrum biopsy specimens were collected at endoscopy for the rapid urease test (Pronto Dry, Medical Instrument Corp, France) and histopathology. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and like-hood ratio of a positive and negative of Pronto Dry test were compared against histology. The gold standard …

Helicobacter Pylori Infection And Micronutrient Deficiencies., Javed Yakoob, Wasim Jafri, Shahab Abid
Section of Gastroenterology
It is known that deficiencies of micronutrients due to infections increase morbidity and mortality. This phenomenon depicts itself conspicuously in developing countries. Deficiencies of iron, vitamins A, E, C, B12, etc are widely prevalent among populations living in the third world countries. Helicobacter pylori (H pylori) infection has a high prevalence throughout the world. Deficiencies of several micronutrients due to H pylori infection may be concomitantly present and vary from subtle sub-clinical states to severe clinical disorders. These essential trace elements/micronutrients are involved in host defense mechanisms, maintaining epithelial cell integrity, glycoprotein synthesis, transport mechanisms, myocardial contractility, brain development, cholesterol …
