[Immune status in diabetic patients with pyo-necrotic lesions of lower extremities].

Long-term and severe pyonecrotic processes in diabetic patients testify to severe disorders of immune system in this disease. High titer of antibodies to tested autostrain demonstrated its etiologic role in infectious process. The study group consisted of 29 patients (with diabetic pyonecrotic foot lesions), control group--17 patients with burns of III a, b--IV stage affecting from 20 to 60% of body surface. In diabetic patients antibodies titer to the most encountered infectious agents Staphilococcus aureus and Pseudomonas aeroginosa was lower than in burn patients with immunity deficiency. Decrease of antibodies titer in diabetic patients testifies to high insufficiency of B-immunity.
