The mortality risk associated with bacteremia withinthe solid organ transplant population is reported to be ashigh as 70%, depending onthe organism, site of infection,and timing of occurrence post transplantation (2).Whenconsidering organ dysfunction across all patient popula-tions, risk of death increases by 15^20% with each addi-tional dysfunctioning organ. Angus et al. (3) reported anin-hospital mortality rate of 64.5% in patients with 3dysfunctionalorgansand76.2%inpatientswith4ormoredysfunctional organs. Trials involving the diagnosis andtreatment of sepsis have excluded solid organ trans-plantrecipientsbecauseoftheiroftenatypicalpresentationand alteredpathogenesis from standardpopulations. How-ever, this population would likely bene¢t the most frompharmacological interventions aimed at attenuating theprogression of sepsis secondary to their depleted immunefunction and altered in£ammatory system. |
