Immunoglobulins in Adult Sepsis and Septic Shock

Abstract

For more than 30years, intravenously administered immunoglobulins (ivIG) have been used to treat primary and secondary syndromes of immune deficiency. Increasing insight into pathomechanisms of severe sepsis and septic shock have led to the implementation of ivIG therapy in the strategies for adjunctive therapy in sepsis in both adults and children. Direct antitoxic effects, as well as indirect immunomodulatory mechanisms of ivIG have been described in the literature and were the basis for the rationale to use these substances in life-threatening infections and hyperinflammatory states. Several clinical trials have been performed, most of them as minor, investigator-initiated protocols. This review summarizes the results of clinical investigations and systematic meta-analyses that have implications for the development of therapeutic strategies, and international guidelines for the management of severe sepsis and septic shock in adult patients.
