[Immunity in hypothyroid children (author's transl)].

For a long time investigators have focused attention on the relationship between specific immunity and hormones. In the present paper, authors investigated on 26 children, 9 males and 17 females, from 9 months to 14 and 10/12 years old, with primary hypothyroidism. All patients were in substitutive treatment. The following studies were done to all the patients: serum IgG, IgA, IgM and complement. Blood lymphocyte counts, percentages of B and T lymphocytes, as well as the response of lymphocytes to PHA. Skin tests were also carried out: tuberculin, candidin and streptokinase-streptodornase. All results obtained in both, hypothyroid and control groups fell within the range of normal age-matched values for our laboratory, and by results of statistics studies carried out they were considered of little significance, except the percentage of circulating B lymphocytes that was lower in hypothyroid group (p less than or equal to 0.01).
