[Fungemia caused by Rhodotorula mucilaginosa in relation to total parenteral nutrition].

BACKGROUND

Fungal infections are nowadays more common in clinical practice. The most frequently isolated fungi are Candida and Cryptococcus. Infection due to Rhodotorula mucilaginosa is very uncommon. We describe here our experience with R. mucilaginosa fungemia, with emphasis on total parenteral nutrition related episodes.

METHOD

A retrospective review identified 3 patients with R. mucilaginosa, and predisposing conditions, clinical features, treatment used and outcome were analyzed. The case definition includes the repeated isolation of R. mucilaginosa in several blood-cultures and/or the isolation of R. mucilaginosa in one single blood culture together with its isolation in any other site.

RESULTS

Three patients were identified. In all of them there are some defects in immune response (skin anergy in two, immunosuppressive therapy in the remaining patient), had an iv line placed, under antibiotic therapy and total parenteral nutrition. All factors could have been related to the development of R. mucilaginosa infection.

CONCLUSION

Although its pathogenic role is controversial, in two or our patients R. mucilaginosa infections correlates well with clinical signs and symptoms of invasive infections (fever, hemodynamic changes). The treatment is still not clear.
