Infusion of reconstituted high-density lipoproteins (rHDL) is being studied
in clinical trials as an adjunctive therapy for gram-negative sepsis. Sinc
e no data are available on its possible effects in systemic candidiasis, we
investigated the effect of rHDL infusion into volunteers on the growth of
Candida albicans. C. albicans growth was 10- to 100-fold higher in the plas
ma of volunteers infused with 80 or 100 mg/kg rHDL than in plasma collected
before infusion; administration of 60 mg/kg rHDL had marginal effects. In
vitro, the isolated lipoprotein subfractions had a growth-promoting effect
on C. albicans. These data suggest potential adverse effects of rHDL if inf
used into patients with systemic candidiasis. Thus, rHDL infusion into pati
ents with sepsis caused by an unknown microorganism may be contraindicated.
