Prediction of sepsis in the multitraumatic patient by assays of lymphocyte responsiveness.
In vitro lymphocyte response to antigens, mitogens and in mixed lymphocyte culture were studied at intervals after injury in 31 patients with extensive trauma. Mean responses were significantly depressed up to 15 to 20 days. Responses were lower and the duration of suppression longer in those patients who become infected, and the suppression of response preceded the onset of infection. Extremely low responses were found in three patients who later died. This in vitro system is suitable for the serial monitoring of patients, as it reflects the extent of injury, infectious sequelae and prognosis. Its results are quantifiable and avoid the problems associated with repeated skin testing.
