Multiorgan dysfunction syndrome in sepsis: Is macrophage activation syndrome secondary to infection?

Abstract

Objective: To assess macrophage activation syndrome (MAS) in septic shock leading to multiorgandysfunction syndrome (MODS).Methods: A prospective observational study was conducted at a tertiary care hospital to evaluate theMAS criteria in different stages of sepsis. Children aged 6 months to 12 years in different stages of septic shock were recruited. The Paediatric Rheumatology International Trials Organisation CollaborativeInitiative (PRINTO) criteria of MAS were applied initially at the stage of septic shock and subsequentlyat the stage of MODS (MODS cohort) or following recovery from septic shock without going throughMODS (non-MODS cohort).Results: A total of 127 subjects were studied, with 53 comprising the MODS cohort and the rest 74 thenon-MODS cohort. At the initial assessment, a comparable proportion of subjects in the MODS andnon-MODS groups satisfied the MAS criteria (20.75% and 25.68%, respectively; p=0.529). However,by the time of progression to MODS, 81.13% of the subjects satisfied the MAS criteria in the MODSgroup, whereas only 16.18% subjects in the non-MODS group continued to satisfy the MAS criteria(p
