Selenium levels in patients with different sources of sepsis.

The aim of this study is to establish whether different types of sepsis have an impact on selenium levels. Selenium is an essential trace element involved in antioxidant and immunological reactions. Selenium levels have been shown to be low in patients with systemic inflammatory response syndrome and sepsis. Selenium replacement has been recommended in patients with sepsis [1,2]. Greater than 5 days of supplementation may also help to prevent the development of new infections on ICUs [3].
