Aim:
To evaluate the relationship between Candida and peptic ulcer.
Methods:
One hundred consecutive patients with untreated peptic ulcer (81 with duodenal ulcer and 19 with gastric ulcer) were studied using histopathology, culture and fungal serology. Twenty subjects with non-ulcer dyspepsia were taken as controls.
Results:
Forty seven patients (47%) with peptic ulcer were colonized by Candida as compared to 3 patients (15%) with non ulcer dyspepsia (p < 0.05). Confluent growth of Candida on culture of gastric aspirate or biopsy from ulcer edge was a more sensitive method for diagnosis of peptic ulcer-associated candidiasis than histological examination. There was no significant difference in the prevalence of Candida isolation in relation to age or sex of the patients, smoking habit and alcoholism. Large ulcers (> 2 cm) were, however, more often colonized by Candida (75%) than smaller ones (43%) (p < 0.05). Candida albicans was the commonest species isolated (60%). Invasive candidiasis was associated with Candida agglutinin titer of 1:128 in 81% of cases.
Conclusion:
Candida colonization rate in peptic ulcer is significantly higher than in non-ulcer dyspepsia.
