Possible defective trauma patients' Mphi-T-cell feedback interactions between T cell IL-13 production and IL-1beta and IL-18 Mphi secretion were assessed. Mphi produced IL-1 and IL-18 augment T cell IL-13, which in turn limits excessive macrophage activation. Immunodepressed patients' T cells (depressed proliferation to alphaCD3 + alphaCD4) had decreased IL-13 production concomitant to aberrant Mphi activities ( upward arrow mTNFalpha, downward arrow IL-10) and consequent multiple organ failure (MOF). Decreased IL-13 levels in patients' T cell and diminished Mphi supernatant augmentation of healthy controls' T cell IL-13 production appeared concomitantly, suggesting patients' aberrant monokine levels might intensify in vivo T cell dysfunction severity. Patients' Mphi supernatants, which failed to augment controls' T cell IL-13 production, had depressed IL-1beta and lower induction of IL-18 than immunocompetent patients' Mphi, but combined addition of IL-1beta and IL-18 restored these Mphis' IL-13 enhancing activity. These data suggest that immunodepressed patients' aberrant monokine and depressed T cell IL-13 production are independent but synergistic contributors to emergence of MOF.
