[Increasing the effectiveness of antibiotic therapy by correcting immunologic disorders with vitamin A in patients with brucellosis].

Experimental studies and clinical trials were performed on possible increase of antibiotic therapy efficacy in brucellosis patients by correction of the immunity disorders with vitamin A. It was experimentally shown that vitamin A increased cellular immunity and accelerated sanation of guinea pigs sensitized with Brucella abortus 19 BA. The clinical trials demonstrated that the use of vitamin A in a dose of 33,000 IU thrice a day for 10 to 12 days during the complex treatment of patients with acute (36 persons) and subacute (57 persons) brucellosis lowered the average period of manifestation of the disease clinical signs and formation of the antibodies, increased the skin allergic sensitivity, the lymphocyte blast cell transformation, the total number and subpopulations of the active T-cells, theophylline-resistant lymphocytes, phagocytic and metabolic activity of neutrophils, showed 1.5- and 2-fold increased in the frequency of the infection transformation into a chronic process in patients with acute or subacute brucellosis, respectively.
