Helicobacter pylori (H. pylori) infection affects one in four Brazilian gastroenterologists, with prevalence increasing with age. Endoscopic procedures do not significantly increase H. pylori risk in these professionals.
Area of Science:
- Gastroenterology
- Infectious Diseases
- Occupational Health
Background:
- Helicobacter pylori (H. pylori) infections are common, often acquired in childhood.
- The occupational risk of H. pylori for gastroenterologists performing endoscopic procedures is not well-established.
Purpose of the Study:
- To determine the prevalence of H. pylori infection among gastroenterologists and gastroendoscopists in Brazil.
- To assess if performing endoscopic procedures increases H. pylori occupational risk.
Main Methods:
- A prospective study involving 286 Brazilian gastroenterologists and gastroendoscopists.
- Participants underwent a 13C-urea breath test (UBT) after a washout period for relevant medications.
- Demographic and professional data were collected via questionnaire.
Main Results:
- Overall H. pylori prevalence was 23.8% (68/286).
- Excluding prior treated infections, current prevalence was 25.1% (55/219).
- No statistically significant difference in H. pylori prevalence was found between those who performed endoscopic procedures (28.4%) and those who did not (23.2%).
Conclusions:
- H. pylori prevalence is moderate among Brazilian gastroenterologists, with approximately 25% infected.
- Infection rates increase with age and are higher in overweight/obese individuals.
- Performing endoscopic procedures does not appear to elevate H. pylori infection risk in this cohort.

Few clinical manifestations differentiate gastric ulcers from duodenal ulcers. Distinctions in the location, timing, and pain relief are crucial for healthcare providers in differentiating between gastric and duodenal ulcers during clinical assessments.

An acute ulcer, marked by superficial erosion and minimal inflammation, swiftly resolves upon identifying and addressing the underlying cause. In contrast, a chronic ulcer persists, potentially eroding through the muscular wall and forming fibrous tissue.

The patient with acute gastritis may have a rapid onset of symptoms, such as epigastric pain or discomfort, dyspepsia, anorexia, hiccups, or nausea and vomiting, which can last from a few hours to a few days. Erosive or hemorrhagic gastritis may cause bleeding, which may manifest as blood in vomit or as...
