Situação atual da triagem neonatal para hipotireoidismo congênito: críticas e perspectivas

Abstract: SUMÁRIOO hipotireoidismo congênito (HC) é uma das causas mais frequentes de deficiência mental passível de prevenção. Esforços devem ser utilizados na sua detecção e no tratamento precoces. O atraso no diagnóstico e no tratamento resultará em sequela neurocognitiva. A triagem neonatal mudou a evolução natural dessa enfermidade. O nível de corte do TSH utilizado é 10 mUI/l. No Brasil, a triagem neonatal é realizada há três décadas. Atualmente todos os estados brasileiros e o Distrito Federal a realizam. Analisa… Show more

“…During recent years, the concern for false-negative screening has been raised in Brazilian NSP, with different neonatal TSH cutoffs (19,20). In our sample, over half of the children with permanent CH and most of the hyperthyrotropinemia cases were diagnosed with neonatal TSH between 5.2 and 10 µU/mL.…”

“…Korada and cols., 2010, decreased the limit for the TSH cutoff from 20 µU/mL to 6 µU/mL and observed that, in 67 children with TSH between 6.1 and 10 µU/mL, 4 continued to display TSH levels greater than 6 µU/mL (23). In the Brazilian state of Santa Catarina, the recommended cutoff point is 6 µU/mL because, at 10 µU/mL, some CH cases can be missed (20). A study conducted in Rio de Janeiro, Brazil, found a significant number of cases of permanent CH screened with neonatal TSH levels between 4.5 and 10 µU/mL (62.6% with confirmatory TSH > 10 µU/ mL), recommending a neonatal TSH cutoff value of 4.5 µU/mL to prevent missed cases despite the inevitable necessity of more confirmatory tests (24).…”
