[Invasive fungal dermatitis in extremely premature newborns: a specific clinical form of systemic candidiasis].
BACKGROUND
Fungal agents, chiefly Candida albicans, are the cause of rising morbidity and mortality in newborn infants weighing less than 1500 g. We studied the particular cutaneous effects during the course of these infections.


METHODS
This was a retrospective 3-year study in premature infants weighing less than 1500 g and hospitalized in the neonatal department of the Lille University Teaching Hospital. The patients included in the study presented sepsis with isolation of Candida in blood and/or urine culture.


RESULTS
Twelve infants were included (1.8%). The risk factors seen are those described in literature (broad-spectrum antibiotics, prolonged mechanical ventilation and parenteral nutrition, corticosteroids and central venous catheters). Infection occurred early (mean: D12) and affected extremely premature infants (mean: 25 weeks' amenorrhea) of low birth weight (mean: 758 g) generally born by vaginal delivery (9 of 12 infants). The sole fungal agent isolated was Candida albicans. In 10 of the 12 patients, a characteristic skin disorder was observed (erythema with erosion and desquamation). In 10 of the 12 patients, too, Candida was isolated from skin and/or mucosal samples.


CONCLUSIONS
Although it is now universally accepted that antifungal treatment should be initiated without delay for candidemia in septic newborn infants at risk, diagnosis of systemic candidiasis remains delicate. However, a specific pattern of skin involvement is very commonly seen that is atypical for candidiasis, but which in addition to its diagnostic value indicates early colonization with Candida (first 2 weeks of life). In this setting of immaturity of the skin and immune system, colonization and proliferation in skin and/or mucosa appear to constitute the first stage of systemic infection and we may speak of invasive cutaneous-mucosal candidiasis in extremely premature infants and initiate treatment designed to prevent the disease becoming systemic..
