Candida Antigen Detection in Two Premature Neonates with Disseminated Candidiasis

Abstract
Two premature neonates with birth weight < 1200 g developed systemic candidiasis during treatment with multiple antibiotics and parenteral hyperalimentation. Clinical findings included signs of necrotizing enterocolitis in 1 patient and multiple fungal renal cortical abscesses in the other. The Candida antigen, mannan, was present in the sera of both patients at the time of clinical deterioration. Multiple blood cultures and urine and stool samples from both patients grew C. albicans. Systemic antifungal therapy was given for a 6-wk period and was associated with prolonged antigenemia despite negative findings on follow-up cultures. Antifungal therapy was stopped soon after antigen was no longer detected. Both patients recovered without evidence of further fungal infection. Candida antigen detection may be useful in the diagnosis and follow-up of premature infants with disseminated candidiasis.
