Summary
Helicobacter heilmannii (Hh) gastritis is rare but requires specific therapy. Histological diagnosis is crucial for differentiating Hh from Helicobacter pylori, as clinical presentations are similar.
Area of Science:
- Gastroenterology
- Microbiology
- Pathology
Background:
- Helicobacter pylori is a common cause of gastritis.
- Helicobacter heilmannii (Hh), previously Gastrospirillum hominis, is a rare bacterium also causing gastritis.
- Hh gastritis diagnosis is critical due to distinct therapeutic needs compared to H. pylori.
Purpose of the Study:
- To report the first Italian series of 14 new cases of Hh gastritis.
- To highlight the importance of histological diagnosis for Hh.
- To present clinical and histological findings in Hh gastritis.
Main Methods:
- Retrospective analysis of 14 Hh gastritis cases.
- Review of gastric biopsies from 1994-1998.
- Histological examination for Hh identification.
Main Results:
- Hh gastritis represented 0.01% of gastric biopsies.
- Patients (9 male, 5 female, average age 50) presented with mild to moderate gastritis.
- Hh was found in glandular mucus, sometimes co-occurring with H. pylori or associated with gastric adenocarcinoma and duodenal ulcer follow-up.
Conclusions:
- The incidence of Hh gastritis in this Italian series aligns with European data.
- Hh presence was consistently associated with gastritis, confirming its pathogenic role.
- Accurate histological diagnosis is essential for appropriate Hh gastritis management.

01:16Treating Helicobacter pylori in Peptic Ulcers: Antimicrobial Therapy
Helicobacter pylori, a resilient gram-negative bacterium, can thrive in the stomach's harsh, acidic environment. Infection with H. pylori leads to a cascade of events within the stomach lining. One of the critical disruptions caused by this bacterium is the interference with somatostatin production, a hormone responsible for regulating acid secretion. This interference tips the balance, escalating acid secretion and diminishing bicarbonate levels. This imbalance compromises the defensive...
01:28Peptic Ulcer Disease III: Clinical Manifestations and Diagnostic Studies
Peptic ulcer disease (PUD) presents with diverse symptoms depending on the location and severity of the ulcer. Clinical manifestations of peptic ulcer include dull pain and a burning sensation in the mid-epigastric region.
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.

01:27Microbiota of the Stomach and Small Intestine
The human gastrointestinal (GI) tract is characterized by distinct physicochemical conditions that shape its microbial communities. Among these, the stomach presents a particularly challenging environment for microbial colonization due to its highly acidic pH, ranging from 1 to 3. This extreme acidity effectively limits microbial density. However, certain acid-tolerant microorganisms are capable of surviving in this niche. Notably, Helicobacter pylori can colonize the gastric mucosa,...
01:27Peptic Ulcer
Peptic ulcers are erosive lesions of the gastric or duodenal lining, most commonly caused by Helicobacter pylori infection. This Gram-negative, helical bacterium has adapted to survive the stomach’s acidic environment by producing urease, which converts urea into ammonia and carbon dioxide. The ammonia neutralizes gastric acid in the bacterium’s immediate environment, allowing colonization of the gastric mucosa. H. pylori attaches to mucus-secreting epithelial cells, penetrates the mucus...
01:28Amebiasis
Entamoeba histolytica, a protozoan parasite, is responsible for intestinal and extraintestinal amebiasis. Though a significant proportion of infections remain asymptomatic, approximately 50 million individuals annually are estimated to present with clinical disease, resulting in up to 100,000 deaths globally. The disease burden is disproportionately high in regions with lower socioeconomic status, such as parts of India, Africa, Mexico, and Latin America.Etiology and TransmissionThe infective...
01:26Gastritis II: Pathophysiology
The pathophysiology of gastritis begins with the colonization of the stomach lining by Helicobacter pylori (H. pylori). This bacterium spreads mainly via the oral-oral route through saliva or shared utensils, and can also be transmitted in overcrowded or unhygienic environments through contaminated water, despite its brief survival outside the body.ColonizationOnce ingested, H. pylori enters the stomach and begins colonization by navigating through the mucus layer lining the stomach wall. It...
