[The cellular immune response in different forms of diphtheria in adults]

In 109 adult diphtheria patients with different forms of the disease (toxic, subtoxic, localized) and carriers, the latter including 6 persons having had the localized form of diphtheria, 12 different subpopulations of T and B lymphocytes and neutrophils were studied by the methods of rosette formation with sheep, mouse and bovine red blood cells. The study showed that, starting from week 2 of the disease, an increase in the content of the subpopulations under study was registered in all forms of diphtheria; the disease, as well as in patients with the localized form of the disease accompanied by complications and in long-term carriers. In all forms of diphtheria a decrease in the content of neutrophil rosette-forming cells was shown. The marker tests for prognostication of the complicated course of the disease, viz. the elevated content of M-rosette-forming cell and T gamma-rosette-forming cells during the first week of then disease, were established.
