Abstract
Intravenous catheter-related bloodstream infections (ICR-BSI) are a major contributing factor to in-hospital mortality and morbidity, extending the inpatient stay by 10 days and expenditure per patient by £2,000 to £30,000 [1]. A prospective survey was conducted in our unit on all patients with central venous catheters to ascertain the incidence of ICR-BSI, identify the organisms and determine the occurrence of infection from the various sites - femoral, internal jugular and subclavian lines.

Conclusions Simvastatin suppressed the induction of nitric oxide caused by LPS and the associated increase in nitrite/nitrate production This finding helps to explain our observation that simvastatin prevented LPS-induced hyporesponsiveness of the coronary artery, and is consistent with clinical studies suggesting that prior use of statins may afford protection against bacterial sepsis. While most animal models of sepsis have studied polymicrobial or Gram-negative sepsis from an abdominal origin in young animals, the most common presentation in the medical ICU is in older individuals (median age 64 years), with Gram-positive bacteria (predominantly Staphylococcus aureus) infection in the lung. High mobility group box 1 (HMGB1) is a pleiotropic cytokine, implicated in the pathophysiology of sepsis This alarmin, usually located in the nucleus, is released after tissue injury and activates various innate immunity receptors, leading to sustained inflammatory response. Several studies suggest independent functioning of S100A9, making it an interesting candidate biomarker in septic syndromes
