[Severe circulatory insufficiency in a patient with neonatal hyperthyroidism].
Authors describe a case of a premature infant whose mother had a history of thyroidectomy due to Graves' disease and her hormonal status was not controlled during pregnancy. She did not receive prenatal care and on 33rd week the premature infant was delivered by emergency cesarean section because of fetal tachycardia and imminent intrauterine asphyxia. The infant with a weight of 1350 gram (percentile <10) was dysmature and had a large struma. The newborn received both conventional and high frequency ventilation for respiratory insufficiency and was treated with beta-blocker, digoxin and dobutamine for severe tachycardia (>180/min) and cardiac decompensation. Further examinations proved cardiomegaly, pericardial fluid, severe pulmonary hypoplasia, mitral- and tricuspid insufficiency and hepatosplenomegaly. The level of free thyroid hormones was several times higher than normal (fT4: > 6 ng/dl, fT3 > 30 pg/ml), while TSH level was 0. Respiratory support was required for 7 days, inotropic support for 10 days; at the same time propranolol and K-iodide were administered. Eventually, the tachycardia settled and beta-blocker therapy was continued with reduced doses. Finally, the thyroid hormone levels became normal. Authors emphasize that newborns of women suffering from Graves' disease can significantly lag behind in weight increase, may have severe circulatory insufficiency and symptoms of thyrotoxicosis. We also emphasize the importance of the monitoring maternal hormone levels and antibody titers.
