Esophageal candidosis in progressive systemic sclerosis: occurrence, significance, and treatment with fluconazole.

Esophageal mucosal brushings from 51 consecutive patients with progressive systemic sclerosis (PSS) (group I), 18 PSS patients continuously treated with high-dose ranitidine or omeprazole (group II), 34 controls referred to the outpatient clinic for endoscopy (group III), and 10 patients receiving long-term potent antireflux therapy for idiopathic gastroesophageal reflux (group IV) were cultured for Candida albicans. There were 44%, 89%, 9%, and 0% Candida albicans culture-positive patients in groups I through IV, respectively. Fifteen patients with candida esophagitis from group II were treated with fluconazole systemically. Eleven and 14 patients became culture-negative after 2 and 4 weeks' treatment, respectively. Three months after fluconazole withdrawal the recurrence rate was 100%. It is concluded that esophageal dysmotility predisposes for candidosis. Adding gastric acid inhibitory treatment to dysmotility enhances the risk significantly (p less than 0.01). The efficiency of fluconazole treatment was close to 100%, but so was the recurrence rate within a short period.
