The influence of macrophage migration inhibitory factor gene polymorphisms on outcome from community-acquired pneumonia.

ABSTRACT: The cytokine, macrophage migration inhibitory factor (MIF), is encoded in a functionally polymorphic locus and subjects with high-expression MIF alleles are at an increased risk of inflammatory disease. Severe sepsis is the leading cause of death in intensive care units, and the prevailing hypothesis is that an excessive innate response contributes to its pathogenesis. To assess if MIF alleles influence the clinical course of infection, we conducted a case-control study to assess susceptibility and a parallel inception cohort study of community-acquired pneumonia (CAP) to assess risk of severe sepsis and 90-d mortality. Two distinct polymorphisms in the MIF promoter were analyzed: a G/C transition at -173 and a CATT repeat at -794. The frequency of both polymorphisms was similar in the CAP
