Lymphocyte-platelet interactions in patients with deep frostbites with various nutritional statuses.

The purpose of the study was to determine the relative number and degree of lymphocyte-platelet adhesion in patients with frostbites of III-IV degree of extremities with malnutrition and eutrophia.

Methods: Non-randomized prospective controlled study was performed in 49 patients of both sexes, aged from 16 to 60 years, with frostbites of III-IV degree of extremities. The object of the study was the blood plasma. Test subjects were divided into two groups according to the trophic status on the scale of Luft V.M and Kostyuchenko A.L. By the original method of the Professor Vitkovsky Yu.A. (1999) number of lymphocyte-platelet coaggregations was counted in 100 cells (percentage), which is relative number of the lymphocyte-platelet adhesion (LTA). In this case lymphocyte which adhered to its surface one or more platelets was named the coaggregation. Lymphocyte-platelet index (LTI) or the degree of LTA was determined as the arithmetic mean of the number of platelets which have adhered to a single lymphocyte.

Results: The relative number of LTA greater in patients with eutrophia (n = 19) vs. (p<0.001) the control group (n = 20) and vs. (p = 0.008) patients with malnutrition (n = 20). The relative number of LTA is not different in patients with malnutrition vs. (p = 0.085) the control group. LTI greater in patients with eutrophia vs. the control group (p<0.001), and vs. patients with malnutrition (p = 0.020). LTI greater in patients with malnutrition vs. the control group (p = 0.006).

Conclusion: It was established that LTI increased irrespective of premorbid trophic status, and LTA percentage increased only in patients with eutrophia. In patients with malnutrition LTA degree and LTA percentage were detected less than in patients with normal nutritional status.
