none of these patients had documentation of development of any further malignancy such as gastric adenocarcinoma or lymphoma. Nevertheless, we believe that detection of H.pylori is important for clinicians as well as pathologists.
Sir, We read with interest the article “Epidemiology and pattern of antibiotic resistance in Helicobacter pylori: Scenario from Saudi Arabia,” by Rizwan et al. reviewing the epidemiology of antibiotic resistance in H. pylori in Saudi Arabia In this context, we would like to share our experience. In the review, the authors mentioned that in developing countries the infection is more prevalent in children as compared with that in adults. They also stated that there may be variations between people of different ethnic groups, age, and gender within the same country. In our study, we found the presence of H. pylori in approximately 62% of gastritis cases by using different staining modalities. Majority of the cases in our study groups were adults. We found that routine hematoxylin stain with special stains such as modified Giemsa and Warthin–Starry can detect H. pylori in a reliable manner. However, with the help of immunohistochemistry, the detection rate of H. pylori was improved as many coccoid forms were also detected.[2,3] Recently, we studied the followup data available for 31 patients with positive detection of H. pylori. The duration of followup was from less than one year to five years. However,

Since the first European Consensus Report on Helicobacter pylori management in 1996 and the strong indication for therapy of peptic ulcer disease and other benign gastroduodenal pathologies, the list of indications for therapeutic interventions has b
After the approval of health insurance coverage of eradication therapy for Helicobacter pylori-positive peptic ulcer disease (PUD) in 2000, comprehensive coverage for H. pylori infection itself was implemented in 2013.
Gastric cancer still is a major concern as the third most common cancer worldwide, despite declining rates of incidence in many Western countries. Helicobacter pylori (H. pylori) is the major cause of gastric carcinogenesis, and its infection insults
Helicobacter pylori relies on multiple colonization and virulence factors to persist in the human stomach for life. In addition, these factors can be modulated and vary to suit the ever-changing environment within the host individual. This article ou
Helicobacter pylori (H. pylori) is a Gram-negative spiral bacterium that is present in nearly half the world's population. It is the major cause of peptic ulcer disease and a recognized cause of gastric carcinoma. In addition, it is linked to non-ulc
Laryngopharyngeal reflux (LPR) occurs when gastric contents pass the upper esophageal sphincter, causing symptoms such as hoarseness, sore throat, coughing, excess throat mucus, and globus. The pattern of reflux is different in LPR and gastroesophage
