PG - 1037-45; discussion 1045-6 AB - BACKGROUND: We have previously shown that an intrinsic postinjury T-cell dysfunction defined as lack of proliferative response to direct stimulation through the T-cell receptor, referred to here as "anergy," occurs in a subgroup of patients with severe trauma and is associated with organ failure. It has been suggested recently that a dominance of T-helper-2 (Th2) lymphokine production might be responsible for immunosuppression and associated with poor patient outcome. Here, we hypothesize that anergy is associated with global failure of T lymphokine (T LK) production, suggesting that poor outcome is not the result of an excess of immunosuppressive T LK (i.e., interleukin (IL)-10) but rather results from lost T-cell regulatory networking. METHODS: Purified T cells from 37 severely injured trauma patients were cultured and stimulated with alphaCD3/alphaCD4, and proliferation was assessed at 72 hours. Anergy is defined as occurring when the patient's T-cell proliferation to alphaCD3/alphaCD4 is less than 50% of the simultaneously run normal proliferation. Culture supernatants were assessed for T LK production by enzyme-linked immunosorbent assay. Clinical severity was measured by the multiple organ dysfunction syndrome (MODS) and Acute Physiology and Chronic Health Evaluation III scores. RESULTS: Anergy occurred in 20 of 37 patients, and it usually appeared at greater than 5 to 7 days after injury. There was a global reduction of T LK production during T-cell anergy (IL-2, 2.5%; interferon (IFN)gamma, 30.5%; IL-4, 11.8%; and IL-10, 16.9%) compared with increased or unchanged T LK production during the nonanergic state (IL-2, 83%; IFNgamma, 230%; IL-4, 110%; and IL-10, 307.9%; p < 0.01). There was a significant direct correlation between depressed IL-4 and depressed IFNgamma (r = 0.620, p < 0.001), indicating a diminished LK production of both types of T-helper cells (Th1 and Th2). Decreased IL-2 and IL-10 levels were also specifically correlated to each other during the anergic state (r = 0.91, p < 0.001). The average MODS score for patients during anergy was significantly higher (7.6) than their MODS score in the absence of anergy (4.0, p = 0.01). When IL-2 and IL-10 were measured simultaneously, a predominance of Th2 LK (IL-10) production would result in an IL-10/IL-2 ratio greater than 1. We found, however, that this ratio was not greater than 1 in 80% of assays in which T cells were anergic (p = 0.01). CONCLUSION: During T-cell anergy there is not a predominance of Th2 lymphokine production but rather a global depression of the T-cell lymphokine profile. Both depressed T-cell proliferation and depressed LK production correlate to poor clinical outcome.
