Background: Oesophageal candidiasis is the most common cause of oesophageal symptoms in patients with AIDS. Antifungal therapy, given as a suspension, may be better tolerated than capsules or tablets in children or patients with oesophageal symptoms. We performed a prospective study of the safety and efficacy of fluconazole suspension.
Methods: Patients with HIV infection; odynophagia, dysphagia, or retrosternal pain; endoscopic evidence of white plaques or exudate in the oesophagus; and microscopic confirmation of fungal infection on biopsy or brushing specimens were eligible. Patients received fluconazole oral suspension (200 mg loading dose followed by 100 mg q.d.s.). Therapy was continued for 2 weeks after symptom resolution. Repeat endoscopy was performed after completion of therapy.
Results: Forty-two patients enrolled in the study: 40 were male, mean (+/- s.e.) age was 37 +/- 2 years and mean CD4 cell count was 67 +/- 14/mm3. One patient was not evaluable because he received amphotericin during the first week of therapy. Symptoms resolved in all 41 evaluable patients; 17 (41%) had resolution by 1 week, 37 (90%) by 2 weeks, and 40 (98%) by 3 weeks. Endoscopic resolution occurred in 35 (95%) of 37 patients who underwent repeat endoscopy. Adverse events (skin rash in 1, nausea/vomiting in 2, elevated liver tests in 2) led to early termination of therapy in 5 patients, all of whom had clinical and endoscopic cure.
Conclusions: Symptoms resolved in 100% of patients with AIDS and oesophageal candidiasis receiving an oral suspension of fluconazole, and 90% of patients had symptom resolution within 2 weeks. Determining whether the more rapid clinical cure in this study, compared with a previous trial which employed capsules, is related to an additional topical antifungal effect of the suspension, will require further study.
