[Phenotyping of blood and bone marrow lymphocytes in children with primary immunologic deficiency].
Subpopulational composition of peripheral blood and bone marrow lymphocytes was studied in 17 children with different forms of immunodeficiency, combined with hematological shifts (agammaglobulinemia--6, mucocutaneous candidiasis--2, selective IgG-deficiency--2, hyper-IgM syndrome--3, cephalo-oculocutaneous telangiectasia (COCT)--2, general, variable immunodeficiency--2 patients; neutropenia was observed in all the patients, lymphopenia--in 13, anemia-in 6 patients. Surface markers were assayed by flow cytofluorometry with monoclonal antibodies OKT3, OKT4, OKT8, OKB7, produced by "Ortho diagnostics". Changes characteristic of certain forms of primary immunodeficiency have been revealed in the subpopulational composition of peripheral blood and bone marrow lymphocytes: decreased helper potential in patients with general variable immunodeficiency, T-lymphocyte deficiency in patients with COCT increased number of phenotype T3 cells and decreased amount of B-cell in agammaglobulinemia patients. Significant heterogeneity has been noted in the parameters of hemogram, myelogram and in the subpopulational composition of peripheral blood and bone marrow lymphocytes in each nosologic form, the group of patients with hyper-IgM syndrome has proved to be most heterogeneic. It has been suggested that the changes in the subpopulational composition of bone marrow lymphocytes may be responsible for primary immunodeficiency and disorders in hemopoiesis.

[Immunohematologic characteristics and course of chronic neutropenia in children with severe decrease of granulocyte maturation].
The clinical course and some immunohematologic parameters of the blood and bone marrow were investigated in chronic neutropenia children with a high break of granulocyte maturation. Heterogeneity of etiopathogenetic mechanisms of the disease has been recorded in this group of children.

[Cyclic neutropenia: a disease or a syndrome?].
Peripheral blood and bone marrow morphology, blood and bone marrow lymphocyte subpopulation composition were studied in two children with cyclic neutropenia, using flow cytofluorometry, monoclonal antibodies, colony-forming capacity of granulocytic macrophagal precursors in semi-fluid agar. The studies were conducted in varying periods of the neutropenic cycle. Differences were revealed in immunohematologic parameters and clinical course of neutropenia in the two patients. The analysis of the literature data and the authors' own observations of the patients with cyclic neutropenia permitted a suggestion on high heterogeneity of pathogenetic mechanisms of this disease.
