[Characteristics of the endocrine and immune systems and lipid metabolism in children with lymphatico-hyperplastic diathesis].

The data on the genealogic anamnesis and of the incidence of lymphohyperplastic diathesis (LHD) are presented. The measurements of the size of the thymus depending on the age were made with account of the thymicothoracic index. Substantial alterations were discovered in the function of the endocrine system (high content of somatotropic hormone, reduced content of ACTH, hydrocortisone, and TTH), a decline of the relative amount of T and B lymphocytes, and persistent hypoimmunoglobulinemia (G, M, A). The high content of total lipids, cholesterol, triglycerides, low density and very low density lipoproteins and the reduced content of high density lipoproteins were detectable since the first months of life, persisting, up to 3 years of life. Children with LHD should be registered in the dispensary second health group since the first months of life.
