Septic neonate rescued by p olymyxin B hemoperfusion

Sepsis caused by g roup B streptococcus has been well controlled with aminobenzylpenicillin, but the incidence of E scherichia coli sepsis has increased in proportion. E. coli is a G ram‐negative bacillus associated with poor prognosis due to the release of endotoxins. Conventional treatment with antibiotics alone may not be sufficient because the inflammatory response exacerbates the unstable hemodynamic status. Polymyxin B hemoperfusion has been established as a treatment option for septic shock in adults. Polymyxin B hemoperfusion adsorbs endotoxins and cannabinoids such as anandamide and 2‐arachidonoylglycerol. Reported herein is a case of severe septic shock induced by E . coli . The concomitant use of polymyxin B hemoperfusion rapidly reduced the requirement for catecholamines and the patient was discharged without short‐term neurological or respiratory sequelae. It is suggested that polymyxin B hemoperfusion might be an innovative therapy for severe sepsis, and could improve outcome.
