To determine the excess length of stay, extra costs, and mortality attributable to nosocomial bloodstream infection in critically ill patients. ⋯ The attributable mortality from nosocomial bloodstream infection is high in critically ill patients. The infection is associated with a doubling of the SICU stay, an excess length of hospital stay of 24 days in survivors, and a significant economic burden.

The effects of administering total parenteral nutrition (TPN) supplemented with the dipeptide of L-alanyl-L-glutamine (Ala-Gln) on gut structure, barrier function, and protein metabolism were investigated in septic rats. Sepsis was induced by the continuous intraperitoneal administration of endotoxin via a miniosmotic pump. Twenty-three rats were divided into two groups and fed parenterally for 5 days. ⋯ The intestinal mucosal weight and villous height were significantly greater in the Ala-Gln group than in the control group. Pathological derangement of the mucosal structure was more marked in the control group than in the Ala-Gln group. These results suggest that TPN supplemented with Ala-Gln preserves the gut structure without decreasing the nitrogen balance under septic conditions.

Clinical Trial Controlled Clinical Trial
Repeated administration of a F(ab')2 fragment of an anti-tumor necrosis factor alpha monoclonal antibody in patients with severe sepsis: effects on the cardiovascular system and cytokine levels.
In an uncontrolled clinical trial the effects of repeated administration of the F(ab')2 fragment of a murine monoclonal anti-tumor necrosis factor alpha (TNF alpha)-antibody (MAK 195F) on cytokine levels and the cardiovascular system were studied in 20 patients with severe sepsis. Patients were treated with a total of 11 single dosages of the anti-TNF alpha-antibody intravenously over 5 days using either 1 mg/kg (n = 10) or 3 mg/kg (n = 10). ⋯ Comparison of our data with recent data from phase I or II trials using a complete murine monoclonal anti-TNF alpha-antibody suggest that the F(ab')2 fragments of the murine monoclonal anti-TNF alpha-antibody may be of similar efficacy. Definitive conclusions, however, with respect to improvement of mortality and improvement of the cardiovascular system, await the results of larger ongoing placebo-controlled trials.

Septicemia is the second most commonly diagnosed problem in the equine neonate, superseded only by the problem of inadequate transfer of maternal antibodies. This article reviews the factors that may put a foal at high risk for developing sepsis, the diagnostic tools used to identify these animals, some of the sequelae of sepsis, and the therapeutic modalities available to the clinician.
