Summary
Helicobacter heilmannii, a spiral bacteria distinct from H. pylori, was identified in a patient with erosive gastritis. Standard H. pylori tests were negative, but H. heilmannii was confirmed via cytology and successfully treated with H. pylori medication.
Area of Science:
- Gastroenterology
- Microbiology
- Pathology
Background:
- Helicobacter heilmannii (H. heilmannii) is a spiral bacterium found in gastric mucosa, distinct from Helicobacter pylori (H. pylori).
- Diagnosis of H. heilmannii can be challenging due to its distinct characteristics from H. pylori.
Observation:
- A 71-year-old male presented with asymptomatic erosive gastritis.
- Endoscopic examination revealed gastritis, and a rapid urease test was positive, but H. pylori specific tests (culture, immunohistochemistry) were negative.
- Touch smear cytology identified spiral bacteria consistent with H. heilmannii.
Findings:
- The patient underwent a medication regimen typically used for H. pylori eradication.
- Follow-up endoscopy showed decreased inflammation and a negative rapid urease test.
- Repeat cytology confirmed the absence of H. heilmannii after treatment.
Implications:
- This case suggests that standard anti-H. pylori therapy may be effective in eradicating H. heilmannii.
- Accurate identification of H. heilmannii through methods like cytology is crucial for appropriate treatment.
- Further research is warranted to establish treatment guidelines for H. heilmannii infections.
