Аннотация
BACKGROUND: Antibody deficiencies encompass a wide spectrum of pathologies and constitute approximately 50 % of primary immunodeficiencies; with cytometry, it is possible to evaluate the immune status rapidly, effectively and at low cost.
OBJECTIVE: To assess, by means of flow cytometry, the cells of patients with three types of primary humoral immunodeficiencies.
METHOD: Using flow cytometry, blood samples from patients and healthy subjects were analyzed with different monoclonal antibodies.
RESULTS: Using various stains, a severe decrease in B lymphocytes was shown in patients with X-linked agammaglobulinemia, as well as a lack of CD154 expression in patients with hyper-immunoglobulin M syndrome, and heterogeneity of B lymphocyte subpopulations in patients with common variable immunodeficiency.
CONCLUSION: Flow cytometry enables early diagnosis of primary immunodeficiencies with a high level of confidence and, in many cases, identification of the genes involved.
