Fungemia due to Torulopsis glabrata in the compromised host

Ten episodes of Torulopsis glabrata fungemia occurring in nine patients with terminal illnesses are described. Eight patients had underlying malignancies and one patient had a plastic anemia. Two episodes of fungemia were considered transient since they were clearly related to the administration of intravenous hyperalimentation (IVH). Most patients were adult women and had solid tumors of the genitourinary tract. Contributory factors were: antibiotic therapy (100%), immunosuppressive drugs (75%), abdominal surgery (63%), IVH (50%), neutropenia (38%), and diabetes mellitus (13%). The clinical course was indistinguishable from a severe bacterial infection. However, endotoxic shock was not observed. The infection was rapidly fatal in four patients. In the remaining five patients, the infection was altered favorably by the discontinuation of infected intravenous hyperalimentation catheters. However, tissue invasion by T. glabrata was found in two of these patients who died shortly thereafter from tumor progression. At autopsy, T. glabrata was identified in tissue sections of the lungs, kidneys, and mucosas of the gastrointestinal and genitourinary tracts. In all cases there was tissue necrosis with a minor inflammatory response consisting of mononuclear cells. To our knowledge, this is the single largest series of T. glabrata fungemia ever reported.
