title: Candida sepsis during total parenteral nutrition: An endogenous infection indicating the severity of patients' disease state.
abstract: Between 1986 and 1989 we encountered 33 episodes of candida sepsis among 1169 patients receiving TPN for a total of 23350 days (2.8% candida infection rate). Total hospital stay averaged 78 (range 10-230) days and patients received TPN for an average of 21.5 (range 3-83) days before developing candida sepsis. Candida sepsis developed in 8 patients (26.6%) hospitalised in an ICU; 6 patients (20%) receiving high doses of glucocorticoids, 5 patients (16.6%) treated by cytotoxic agents; 23 patients (76.6%) received various combinations of broad-spectrum antibiotics. The number of tubes going in or out numbered an average of 3.6/patient (peripheral and/or central I.V.; endotracheal; tracheostomy; urinary catheter; arterial line; abdominal or chest drains). 18 patients underwent 38 (2.1/patient) operative procedures. 20 patients (66%) suffered fron mono- or polymicrobial bacterial sepsis in addition to candida sepsis, 16 of them metachronously. Candida species isolated were C. albicans - 14 patients; C. tropicalis - 6 patients; C. parapsylosis - 6 patients; not specified - 4 patients. In addition to positive blood cultures we found positive candida cultures in urine, peritoneal cavity, chest cavity, wounds, respiratory tract, intravascular catheters, often in more than one site per patient. All patients were treated with Amphotericin at an average dose of 770 mg/patient. Mortality rate in patients with candida sepsis was 33%. TPN associated candida sepsis seems to be an endogenous self-infecting process in a select group of severely injured-infected-depleted-immunosuppressed patients and is thus completely different from the usual exogenous bacterial TPN associated sepsis. The major risk factors for fungaemia and candida sepsis are the combination of severe underlying disease state, multiple surgical interventions and intravascular lines, the use of broad spectrum antibiotics, TPN, injury and malnutrition associated immunosuppression, multiple tubes and catheters, and intra-abdominal or intra-thoracic infection.
