Central venous catheters are used widely for a variety of therapeutic purposes and have an increased incidence of infections related to their use. The purpose of this article is to address the issue of central venous catheter-related infections, including pathogenesis, predictors and diagnosis, and prevention.

Comparative Study
Reduced tumor necrosis factor production in endotoxin-spiked whole blood after trauma: experimental results and clinical correlation.
The overproduction of tumor necrosis factor-alpha (TNF) plays a key role in virtually every experimental model of septic shock, which has led to the development of several therapies that target TNF and other cytokines in clinical sepsis. However, our previous work showed that plasma TNF was reduced, rather than increased, when a septic challenge was administered 3 days after hemorrhagic shock. In this study we compared whole-blood TNF production ex vivo in human beings and animals after trauma. ⋯ There was no evidence of TNF overproduction in whole blood after trauma. If these results could be generalized to other tissues, it would be difficult to justify therapeutic targeting of TNF in exaggerated inflammatory response (or septic complications) after trauma.

Comparative StudyReduced intestinal absorption of arginine during sepsis.
To investigate the effect of sepsis on the intestinal absorption of arginine. ⋯ Experimental sepsis, induced by either cecal ligation and puncture or intraperitoneal injection of lipopolysaccharide, resulted in impaired intestinal amino acid uptake. Impaired intestinal arginine absorption may explain the lack of benefit of enteral, compared with parenteral, arginine therapy on survival from a septic insult.

Randomized Controlled Trial Multicenter Study Clinical Trial
Interleukin-1 blockade attenuates mediator release and dysregulation of the hemostatic mechanism during human sepsis.
To define the influence of interleukin-1 activity on coagulation and fibrinolytic system activation and the release of proinflammatory mediators in the early human response to severe infection. ⋯ The results confirm that activation of the coagulation and fibrinolytic systems and release of soluble inflammatory mediators are consistently observed in patients with severe sepsis syndrome. Interleukin-1 activity contributes to activation of these processes as documented by the reduction in surrogate activation markers during recombinant human interleukin-1 receptor antagonist treatment.
