RESUMO
The authors relate the data on the incidence of different forms of immune deficiency (ID). The studies were carried out within the framework of the All-Union program of mass immunoepidemiological screenings, among the childhood population of industrial city numbering 59,178 persons. The primary group at ID risk amounting to 2.2% was distinguished. Based on the clinico-anamnestic data a group at higher ID risk was made up (n-421). 450 children were examined by the level I tests. The children were characterized clinicoimmunologically according to different immunopathological syndromes. All the children with the identified forms of ID and those without well-defined forms of immunodeficiency conditions but with steady alterations of the immunologic parameters and the clinical signs need prophylactic medical examinations.
