[Is endoscopic diagnosis of Candida albicans esophagitis reliable? Correlations with pathology and mycology]. / Le diagnostic endoscopique d'oesophagite à Candida albicans est-il fiable?

AIM OF STUDY: To assess the reliability of endoscopic diagnosis of Candida albicans esophagitis. PATIENTS AND METHODS: A case - control prospective study was carried out from November 1997 to July 1998 at the Campus Teaching Hospital of Lome, in patients with esophagitis macroscopically suggestive of Candida albicans origin at upper digestive endoscopy. Fifteen subjects with normal endoscopy served as controls. Esophageal biopsies for mycologic and pathological examination were performed, as well as HIV serology. RESULTS: During the study period, 26 of the 850 endoscopies performed in our Unit revealed an esophagitis suggestive of Candida albicans origin. Mycology confirmed the presence of filamentous form of Candida albicans in 23 patients and pathology showed non-specific lesions of esophagitis, 20 with intramucous hyphae. HIV serology was positive in 19/23 patients (82.6%) and in 1/15 controls (6.6%). Sensitivity and specificity of upper GI endoscopy for the diagnosis of Candida albicans were 100 and 83.3% respectively; positive and negative predictive values were 88.5 and 100%, respectively. CONCLUSION: Upper digestive endoscopy is a reliable method for the diagnosis of Candida albicans esophagitis. However, mycological confirmation is warranted.
