Abstract: | Expression of total T- and B-population, T-subpopulation lymphocyte receptors and secretion of IgM, IgG and IgA were measured in 112 patients with diffuse purulent peritonitis and 81 healthy donors. Expression of receptors was correlated with the disease severity identified by leukocytic index of intoxication (LII). The latter appeared to accurately reflect the pattern of immunological impairment. Reduced absolute and proportional values of total pools of T-, B-cells and T-helpers, but elevated ones of T-suppressors and T-amplifiers occurred in LII less than 2.0. In LII greater than 7.0 there was total suppression of all the cellular populations due to deep lymphopenia. At the terminal stage of peritonitis paralysis of T-helper receptors and B-cells went in parallel with high secretion of serum immunoglobulins. |
