Risk factors for esophageal candidiasis

Area of Science:

• Gastroenterology
• Infectious Diseases
• Pharmacology

Background:

• The role of gastric acid inhibitors in predisposing individuals to Candida esophagitis remains unclear.
• Candida esophagitis is a significant opportunistic infection, particularly in immunocompromised or debilitated patients.

Purpose of the Study:

• To investigate the potential role of gastric acid inhibitors, specifically omeprazole, as predisposing factors for Candida esophagitis.
• To identify risk factors associated with the development of esophageal candidiasis in human immunodeficiency virus (HIV)-negative patients.

Main Methods:

• A retrospective case-control study was conducted involving HIV-negative patients diagnosed with esophageal candidiasis between January 1991 and December 1997.
• Diagnosis of esophageal candidiasis was confirmed through endoscopic and histological examination.
• Multivariate analysis was employed to assess the association between various factors (neoplasms, antibiotic, steroid, and omeprazole therapy) and the occurrence of esophageal candidiasis.

Main Results:

• Fifty-one patients were diagnosed with esophageal candidiasis. A significant proportion had pre-existing chronic diseases (48 patients) or had received prior treatments with antibiotics (20), steroids (13), or omeprazole (14).
• Multivariate analysis revealed significant associations between esophageal candidiasis and neoplasm (OR, 5.50), antibiotic therapy (OR, 11.97), steroid therapy (OR, 35.52), and omeprazole therapy (OR, 18.23).
• The odds of developing Candida esophagitis were substantially increased with prior exposure to antibiotics, steroids, and particularly omeprazole.

Conclusions:

• Candida esophagitis is more likely to occur in patients with chronic diseases who have been treated with antibiotics, steroids, or omeprazole.
• The findings strongly support the hypothesis that omeprazole treatment contributes to the development of esophageal candidiasis.
• These results highlight the importance of considering medication history, including gastric acid inhibitors, in the management of patients with suspected Candida esophagitis.
