Neonatal sepsis and meningitis in a developing Latin American country.
In a retrospective study at Hospital del Niño in Panama City, Panama, 577 neonates with culture-proved sepsis and/or meningitis were identified during an 18-year period (1975 to 1992). Overall there was an incidence of 3.5 cases/1000 live births. Three hundred thirty-three patients (58%) were of low birth weight (< 2500 g) and 260 (45%) were premature. ⋯ The case-fatality rate was 32%. Mortality was greater in infants with early onset sepsis than in those with late infections (44% vs. 22%, P < 0.0001; odds ratio, 2.8; 95% confidence interval, 1.9 to 4.1) and lesser in neonates infected by coagulase-negative staphylococci than in those infected by any other pathogen (12 vs. 39%, P < 0.001; odds ratio, 0.2; 95% confidence interval, 0.1 to 0.4). These findings provide guidelines for the selection of empiric antimicrobial agents in our country and possibly in other Latin American countries and suggest that a continued thorough epidemiologic evaluation is needed to anticipate bacteriologic changes over time.

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.
