Proliferation of human bone marrow cells in vitro: inhibition by Candida albicans components.

We studied the influence of human recombinant granulocyte-macrophage colony-stimulating factor (rhGM-CSF) and Candida albicans (CA) components, either alone or in combination, on the proliferation of human bone marrow cells in vitro (colony-forming assay). The number of colonies per 10(5) bone marrow cells after cultivation with rhGM-CSF [maximal (plateau) colony formation] was: 46.2 +/- 9.1 (n = 6); after cultivation with rhGM-CSF in combination with CA components the numbers of colonies were as follows: 0.05 mg protein/ml, 33.4 +/- 4.6 (n = 3); 0.10 mg protein/ml, 20.8 +/- 3.6 (n = 3). The mechanisms responsible for this inhibition of colony formation are still unknown. They may be of pathogenetic significance in CA infection.

Candidosis of the urinary tract with padding phenomenon of the renal pelvises in an infant with obstructive uropathy.

A male infant with obstructive uropathy developed yeast cell agglomerations which were detectable macroscopically and by image-generating techniques within both renal pelvises after Candida albicans infection of the urinary tract. Therapy with flucytosine induced excretion of 'fungal balls' via the urethra. Continuation of therapy with liposomal amphotericin B (AmBisome) prevented a relapse after development of fungal resistance against flucytosine. Sonographically or radiographically detectable formation of 'concrements' within the urinary tract of patients with an immature or compromised immune system and additional features such as obstructive urinary tract should suggest a localized or systemic mycosis, particularly in the context of long-term antibiotic treatment.
