Introdução

O que você precisa saber de cara

💬
EM LINGUAGEM SIMPLES

O hipotireoidismo congênito permanente é uma condição que se inicia ao nascer, na qual o corpo não produz hormônios da tireoide em quantidade suficiente de forma definitiva. O quadro pode vir acompanhado de sinais como sonolência, **hipoglicemia** (baixa de açúcar no sangue) e traços faciais característicos. No Brasil, a suspeita costuma começar logo nos primeiros dias de vida com o exame do pezinho por meio do TSH neonatal em papel-filtro. O Ministério da Saúde possui um PCDT aprovado para Hipotireoidismo Congênito, classificado com nível de cobertura parcial no sistema público de saúde.

Early prediction of transient versus permanent congenital hypothyroidism: a retrospective cohort study.

Annals of pediatric endocrinology &amp; metabolism2026 Feb

Early differentiation between transient congenital hypothyroidism (TCH) and permanent congenital hypothyroidism (PCH) is crucial for optimizing the duration of treatment. This retrospective cohort study aimed to evaluate whether levothyroxine (LT4) dose requirements over time can predict TCH and guide earlier discontinuation of treatment. We retrospectively analyzed 105 infants with congenital hypothyroidism and normal thyroid glands confirmed by imaging at a single tertiary care center (Inha University Hospital) between January 2013 and December 2022. Patients were classified into TCH (n=70) or PCH (n=35) based on thyroid function after LT4 withdrawal at 3 years of age. LT4 dose/kg at 6, 12, and 24 months, along with clinical and biochemical parameters, were compared between the 2 groups. Receiver operating characteristic (ROC) curve analysis was used to assess the predictive performance of LT4 dose thresholds. The LT4 dose was significantly lower in the TCH group at 6 (3.16±0.83 μg/kg vs. 3.75±0.99 μg/kg, P=0.005), 12 (2.51±0.82 μg/kg vs. 3.37±1.17 μg/kg, P&lt;0.001), and 24 months (2.02±0.61 μg/kg vs. 3.09±1.19 μg/kg, P&lt;0.001). ROC curve analysis showed an area under the curve (AUC) of 0.649, 0.746, and 0.794 at 6, 12, and 24 months, respectively. A logistic regression model incorporating LT4 dose, birth weight, and thyroid-stimulating hormone (TSH) levels improved prediction accuracy (AUC: 0.740, 0.782, 0.833 at 6, 12, and 24 months, respectively). LT4 dose requirements at 6, 12, and 24 months serve as useful indicators for differentiating TCH from PCH. A combined predictive model incorporating LT4 dose, birth weight, and TSH levels may improve diagnostic accuracy, supporting earlier discontinuation of treatment.

Permanent or Transient Congenital Hypothyroidism: A Diagnostic Dilemma.

Acta paediatrica (Oslo, Norway : 1992)2026 Jan

Distinguishing between transient congenital hypothyroidism (TCH) and permanent congenital hypothyroidism (PCH) remains clinically challenging and is typically deferred until the age of 2-3 years, to minimise the potential risk of adverse neurodevelopmental effects due to treatment cessation. However, evidence suggests that earlier discrimination may be feasible, thus avoiding unnecessary, potentially harmful, prolonged levothyroxine (LT4) treatment. This narrative review aims to provide an overview of the current literature regarding potential predictive markers for distinguishing PCH from TCH. A comprehensive search of the PubMed and Google Scholar databases was independently performed by two authors to identify studies that evaluated the utility of several predictive factors. A total of 27 studies were included. The most commonly proposed predictors were thyroid imaging findings, thyroid-stimulating hormone (TSH) levels at diagnosis, LT4 doses at various time points during the treatment period, absolute daily LT4 dose, and episodes of TSH elevation above the reference interval during treatment. Despite these advances, no single marker or combination of markers has yet proven definitive in reliably differentiating PCH from TCH. Further research is needed to establish predictive models that could facilitate the early identification of TCH and the timely and safe treatment withdrawal.

Term birth and levothyroxine dosage are significant factors associated with permanent congenital hypothyroidism: experience from a medical center in Taiwan.

BMC pediatrics2025 Oct 14

Before the introduction of newborn screening, congenital hypothyroidism was the leading cause of intellectual disability in infants and children. Patients with permanent congenital hypothyroidism require lifelong levothyroxine supplementation to prevent intellectual disability and growth failure. With progressively lower thyrotropin (TSH) cutoffs in newborn screening programs, more transient congenital hypothyroidism cases-requiring only temporary treatment-have also been identified. To avoid unnecessary medication use and reduce the burden on healthcare systems, early differentiation is essential. We retrospectively enrolled congenital hypothyroidism patients born between 2004 and 2018 and followed at MacKay Children's Hospital and classified them as permanent congenital hypothyroidism or transient congenital hypothyroidism based on levothyroxine dependence. Basic demographic data, including gender, gestational age, birth weight, newborn screening TSH levels, body height and weight, serum free T4, TSH levels, levothyroxine doses at every clinical visit, and age of TSH normalization were collected and compared between permanent and transient congenital hypothyroidism groups. A total of 152 infants were enrolled in this study, with 73 (48%) classified as permanent congenital hypothyroidism. Term births were more common in permanent than transient congenital hypothyroidism (80% vs. 48%, p < 0.01). TSH normalization took longer in permanent congenital hypothyroidism (75 vs. 45 days, p < 0.01). Serum TSH and levothyroxine doses remained higher in permanent congenital hypothyroidism at 6 months, and at 1, 2, and 3 years. The levothyroxine dose that provided the best discrimination between permanent and transient congenital hypothyroidism was 2.5 𝛍g/kg/d at age 2 years (sensitivity: 73%, specificity: 90%), and 1.8 𝛍g/kg/d at age 3 years (sensitivity: 82%, specificity: 91%). Nearly half of the patients required lifelong levothyroxine supplements under the current newborn screening program. Permanent congenital hypothyroidism patients were more likely term-born, showed delayed TSH normalization, had higher TSH levels, and required higher levothyroxine doses during follow-up. The best cut-off level to discriminate permanent from transient congenital hypothyroidism was 2.5 and 1.8 µg/kg/day at the age of 2 and 3 years, respectively.

Congenital hypothyroidism in two children affected by Sotos syndrome: a simple association?

Italian journal of pediatrics2025 Sep 29

Congenital hypothyroidism (CH) is the most common congenital endocrine disorder and one of the most preventable causes of intellectual disability. The underlying etiology of CH can be thyroid dysgenesis or dyshormonogenesis, and in rare cases, CH can occur as part of a genetic syndrome. Sotos syndrome is a rare overgrowth disorder caused by pathogenic variants in the NSD1 gene, characterized by excessive growth in infancy, distinctive facial features, and developmental delay. We describe two unrelated children with permanent CH and genetically confirmed Sotos syndrome. Both children were referred to our Pediatric Endocrinology Centre due to abnormal thyroid-stimulating hormone (TSH) values detected through neonatal screening. A permanent CH was confirmed in both cases: one patient had thyroid hypoplasia with the presence of only the right thyroidal lobe; the other one had an in-situ thyroid gland. The diagnosis of Sotos syndrome was made later in infancy. In the first case, auxological parameters at birth were within normal ranges and overgrowth became apparent after six months of age; in the second case, overgrowth was already manifest at birth, but the diagnosis was guided primarily by the neurodevelopmental delay. We describe two cases in which CH occurred with Sotos syndrome, and we hypothesize that this association may not be coincidental. To our knowledge, these are among the few reported cases of genetically confirmed Sotos syndrome associated with permanent congenital hypothyroidism. Further studies are needed to determine whether CH is a clinical feature of Sotos syndrome or an unrelated finding. We recommend early thyroid function testing in patients with Sotos syndrome and suggest suspecting Sotos syndrome in children presenting with CH, cognitive delay and overgrowth or additional congenital anomalies.
