title: T-lymphocyte analysis in the early diagnosis of adult respiratory distress syndrome.
abstract: Adult respiratory distress syndrome occurs concomitantly with a number of clinical conditions but has no known cause. At present, there is no generally acceptable method for establishing the early diagnosis. In the course of studying immune aberrations by means of monoclonal antibody staining and fluorescence-activated cell sorting in injured patients, we noted an apparent specific T-lymphocyte response to this syndrome in one patient. There was an increase in suppressor T-cells and a decrease in helper/suppressor T-lymphocyte ratio (normal = 1.57). When the patient recovered, the helper/suppressor ratio rose to above 3.0. T-lymphocyte analysis offers a promising means of evaluating patients considered highly susceptible to adult respiratory distress syndrome, i.e., victims of massive trauma. Further studies will be required to fully elucidate this possibility.
