Resumos

Os autores estudaram a função tireóidea (T-3, triiodotironina; T-4, tetraiodotironina e captação do I131 pela tireóide com 2 e 24 horas após a ingestão do radioisótopo) em pacientes com síndrome de Down, e compararam os resultados com os obtidos nos seus respectivos irmãos, todos clinicamente normais. Os resultados comparativos não apresentaram diferenças significativas, exceto na captação de 2 horas do I131 pela tireóide (P < 0,01). Os achados sugerem que o estímulo hipotálamo hipofisário ou a resposta da glândula tireóide seria lento (a) mas compensado (a) quando analisados após 24 horas.

The thyroid function (T-3 triiodothyronine; T-4 tetraiodothyronine and the captation of the I131 through the thyroid, in 2 and 24 hours after the intake of isotope radium), was studied in patients with Down's syndrome and the results being compared to those obtained from the respective siblings, all clinically normal. The comparative results showed no significant differences, except in the 2 hours captation of the I131 through the thyroid (P < 0.01). The findings suggest that the hypothalamus-hypophysary or the response of the thyroid gland would be slow, but compensated when analyzed after 24 hours.

SUMMARY

The thyroid function (T-3 triiodothyronine; T-4 tetraiodothyronine and the captation of the I¹³¹ through the thyroid, in 2 and 24 hours after the intake of isotope radium), was studied in patients with Down's syndrome and the results being compared to those obtained from the respective siblings, all clinically normal. The comparative results showed no significant differences, except in the 2 hours captation of the I¹³¹ through the thyroid (P < 0.01). The findings suggest that the hypothalamus-hypophysary or the response of the thyroid gland would be slow, but compensated when analyzed after 24 hours.
