Clinical Trial Summary

The purpose of the study is to investigate the role of the human immune response to candidemia/invasive candidiasis as it relates to the cytokine interferon-gamma.

Description:

In this study, patients with Candida bloodstream infection, peritonitis/intra-abdominal abscess, and pleural empyema will be enrolled.

Persistent candidiasis confirmed by culture will be defined as follows: (i) Candida bloodstream infection present for >48 hours after initiation of effective antifungal treatment and after removal of intravenous devices, (ii) Intra-abdominal infection (peritonitis or abscess) that persists for >96 hours after source control intervention and effective antifungal treatment, (iii) Pleural empyema that persists for >96 hours after placement of drainage catheter and effective antifungal treatment.

Outcomes in patients with and without persistent candidiasis will be assessed.
