Thyroid iodide clearance and radioiodide uptake in protein-calorie malnutrition.

摘要: The thyroid function was evaluated in two comparable groups of 12 protein-calorie malnourished children respectively by oral and intravenous test using radioiodine 131I. Maximal radioiodide uptake (RAIUmax) peaked within 24 hr the intravenously investigated children, but only after 48 orally children. In both malnutrition groups, mean RAIUmax significantly decreased comparison with normal (P less than 0.01). RAIU curve reached intermediate values ranging from subnormal to about nearly half normal. Thyroid clearance early depressed some cases, dropped as low one tenth 0.001), reflecting a severe involution. There is high correlation between (r = 0.95); regression line defined equation Y 1.12X + 17.08. Both functional parameters activity appear be mainly lowered relation duration protein deficiency.
