Esophageal candidiasis in HIV-negative patients.

UNLABELLED

Candida esophagitis is the most frequent esophageal infection in HIV seropositive as well as in seronegative patients.

AIM

this retrospective study was designed to determine the characteristics of this disease in HIV negative patients in a general hospital.

DESIGN

clinical records of all HIV negative patients with Candida esophagitis, which was endoscopically diagnosed and microscopically confirmed (biopsy and/or cytology of esophageal mucosa), were studied.

RESULTS

thirty-one patients (23 men, 8 women, mean age: 65.4 +/- 14.3 years, median 71) fulfilled the criteria (0.56% of the diagnostic esophagogastroduodenal endoscopies). The most common clinical symptoms were dysphagia with or without odynophagia and pain (retrosternal, epigastric or xiphoid). Fourteen patients (45%) had no esophageal signs; in nine of them (29%) the disease was diagnosed in the course of an endoscopic exam to investigate the sources of acute or chronic anaemia. The most frequent predisposing factors were diabetes mellitus, oral or aerosolized corticotherapy, malignancies, treatment with broad-spectrum antibiotics and liver cirrhosis. Nine patients (29%) presented no known predisposing factors. The most common endoscopic appearance was grade II (51%). Sixty-one per cent of the patients exhibited at least one other esophagogastroduodenal endoscopic lesion associated with the mycosis. Three patients died of their underlying diseases within one week of the diagnosis of the candidiasis. Only one patient presented persistence of candidiasis one week after initiating treatment with oral nystatine.

CONCLUSIONS

esophageal candidiasis is infrequent and does not always present with suspicious symptoms or known predisposing factors. Aerosolized corticotherapy may be a risk factor for the development of esophageal candidiasis.
