Abstract: | The results of the study of the phagocytic element of immunity in cases of primary immunodeficiency, made with the use of a complex of functional tests, are presented. As shown in this study, in patients with definitely characterized phagocytic defect (chronic granulomatous disease) a decrease in all parameters under study, with the exception of phagocyte index, is observed. In patients with immunodeficient states of nonphagocytic nature moderate mosaic deviations of phagocytosis characteristics are noted. For further and more profound study of phagocytosis disturbances in such patients, it is expedient, in particular, to carry out studies in the activity of myeloperoxidaze and the intensity of oxygen-dependent metabolism. The use of the complex of methods used in this investigation has shown their high diagnostic value. It may be recommended for clinical practice under the condition of strict standardization of experimental techniques. |
