Hipertireoidismo na gravidez: repercussões materno-fetais Hyperthyroidism during pregnancy: maternal-fetal outcomes

OBJETIVO: avaliar a experiência do Hospital das Clínicas da Faculdade de Medicina de Botucatu da Universidade Estadual Paulista "Júlio de Mesquita Filho", no acompanhamento de gestantes com hipertireoidismo. MÉTODOS: foram estudadas, retrospectivamente, 60 pacientes, divididas em grupos com hipertireoidismo compensado (GHC=24) e com hipertireoidismo descompensado (GHD=36) e comparadas quanto a características clínico-laboratoriais e intercorrências. Para análise dos resultados, foram utilizados o teste t de Student, as tabelas de contingência, regressão linear múltipla e regressão logística múltipla, com nível de significância de 5,0%. RESULTADOS: propiltiouracil (PTU) foi usado por 94,0% do GHD e 42,0% do GHC (pPURPOSE: to evaluate the experience of Hospital das Clínicas da Faculdade de Medicina de Botucatu da Universidade Estadual Paulista "Júlio de Mesquita Filho", in the follow-up of pregnant women with hyperthyroidism. METHODS: Sixty patients, divided in groups with compensated hyperthyroidism (CHG=24) and with uncompensated hyperthyroidism (UHG=36) were retrospectively studied and compared concerning clinical-laboratorial characteristics and intercurrences. The t-Student test, contingency tables, multiple linear regression and multiple logistic regression with significance level at 5.0% were used. RESULTS: propylthiouracil (PTU) was used by 94.0% of UHG and by 42.0% of CHG (p<0.0001); maternal complications close to delivery have occurred in 20.6% of UHG and in 11.8% of CHG, and UHG presented three fetal deaths, influenced by the mother age, higher level of T4L (lT4L) and of PTU dose (PTUd) in the third trimester (p=0.007); restriction of intra-uterine growth, influenced by lT4L and PTUd in the third trimester has occurred in nine UHG and in three CHG cases, and oligoamnios has occurred in 12 patients (83.3% of UGH and 16.7% of CGH), influenced by age and lT4L in the third trimester (p=0.04); the gestational age at delivery was 34.4±4.6 weeks in UHG and 37.0±2.5 in CHG, influenced by the T4Ll in the third trimester (p
