[Lymphocyte and neutrophil cytochemistry in the dynamics of different forms of diphtheria in adults]. / Tsitokhimiia limfotsitov i neitrofilov v dinamike razlichnykh form difterii u vzroslykh.

The cytochemical study of lymphocytes and neutrophils isolated from fractionated blood of diphtheria patients and carriers has revealed that a decrease in the activity of lymphocyte succinic dehydrogenase and myeloperoxidase can be observed at all periods of the disease and in all its forms. A decrease in the activity of lymphocyte nonspecific esterase has been noted only in patients with toxic and subtoxic diphtheria and a decrease in the activity of neutrophil alkaline phosphatase, in carriers. The analysis of correlations between the parameters of five enzymes under study (lymphocyte succinic dehydrogenase, lymphocyte acid phosphatase, lymphocyte non-specific esterase, myeloperoxidase, neutrophil alkaline phosphatase) and enzymatic rosette parameters has been made. The analysis has revealed an essential increase in the number of correlations in comparison with donors, changes in the qualitative nature of these correlations and sometimes the reversion of the correlations. Carriers have shown the greatest number of correlations. By the end of the terms of observations no restoration of normal correlations has been observed.

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.
