OBJECTIVE: To observe the effects of initial doses and treatment timing of levothyroxine (L-T4) on the clinical efficacy in children with congenital hypothyroidism (CH). METHODS: This study included 98 children who had an abnormal level of thyroid stimulating hormone (TSH) in neonatal screening in four regions of Yunnan Province and who finally had a confirmed diagnosis of CH. They received treatment with L-T4 and were divided into standard dose group (10-15 μg/kg per day) and low dose group (<10 μg/kg per day) by the therapeutic dose of L-T4...

There is a frequently encountered subset of hypothyroid patients who are refractory to standard thyroid hormone replacement treatment and require unexpectedly high doses of levothyroxine. In addition to clinical situations where hypothyroid patients are non-compliant, or where there is the possibility of excipient-induced disease exacerbation (gluten/celiac disease), therapeutic failure may be due to impaired absorption of the administered drug. The common approach to managing patients with unusual thyroxine needs is to escalate the dose of levothyroxine until targeted TSH levels are achieved...

PURPOSE: Congenital hypothyroidism (CH) is the most common cause of preventable mental retardation. Recently, the detection of CH cases with eutopic thyroid gland has increased due to neonatal screening programs. In this study, we aimed to identify and evaluate predictive factors that could distinguish between permanent and transient CH in patients with eutopic thyroid gland. METHODS: We retrospectively reviewed 100 children diagnosed with CH and with eutopic thyroid gland...

Oral disorders were observed in children with congenital hypothyroidism, lately apparent because of difficulties of feeding, swallowing disorders, and macroglossia. Macroglossia was also a component of the severe acquired myxedema, particularly observed in hypothyroidism related to autoimmune atrophic thyroiditis beyond menopause. Lingual ectopy in children and adults could determine respiratory gene or swallowing difficulties, and were detectable by visual examination and the endobuccal touch. Expression of these events was completely minimized since the neonatal screening of congenital hypothyroidism, also by the common practice in adults of serum TSH determinations...

OBJECTIVE: The purpose of this study was to determine if infants with congenital hypothyroidism (CH) whose initial dose of levothyroxine (LT4) is based on thyroid gland anatomy require fewer dose adjustments in the first six months of life than those who were started empirically on LT4. METHODS: Newborns with CH who had a thyroid ultrasound performed at diagnosis were eligible for this prospective, historical case-controlled study. The daily LT4 dose prescribed was based on results on the thyroid ultrasound as follows: 15 mcg/kg for athyreosis, 12 mcg/kg for a dysgenetic thyroid, and 10 mcg/kg for an anatomically normal gland...

BACKGROUND: Subclinical hypothyroidism (SCH) is defined as high TSH and normal thyroxine. Data on the effects of early substitution by levothyroxine on psychophysical health in SCH are still not consistent enough to support its introduction. METHODS: Clinical parameters, biochemical data and quality of life (Short Form 36 questionnaire) were measured before the intervention and 3 months after the euthyroid state had been achieved in SCH patients. RESULTS: Significant reduction in body weight (p=0...

Infantile hepatic hemangioendothelioma (IHHE) is the most common benign vascular liver tumor and typically occurs during the first 6 months of life. A 4-month-old male patient presented with abdominal distention. A physical examination revealed massive hepatomegaly. Liver enzyme levels were normal. The alpha fetoprotein level was 1,323 mg/dL (6-1,000). Abdominal magnetic resonance imaging (MRI) showed multiple, well-defined and hyperintense nodular lesions in the liver. MRI findings suggested IHHE. The thyroid stimulating hormone (TSH) level was high (177...

The prognosis of primary congenital hypothyroidism, which has potentially devastating effects on neurodevelopment, has been almost eradicated after the implementation of the neonatal screening programme. Although early facilitation with substitution of levothyroxine is preventative, caution should still be taken in severe cases, as subtle psychomotor delays may occur. Treatment dose may be indicative of the severity and pathology behind the condition and can be used as guidance when deciding which patients should have a trial of levothyroxine in cases where the thyroid gland remains in situ...

PURPOSE OF REVIEW: A subset of patients being treated for hypothyroidism do not feel well while taking levothyroxine (LT4) replacement therapy, despite having a normal serum thyroid stimulating hormone level. Pursuing a relative triiodothyronine deficiency as a potential explanation for patient dissatisfaction, has led to trials of combination therapy with liothyronine (LT3), with largely negative outcomes. This review attempts to reconcile these diverse findings, consider potential explanations, and identify areas for future research...

BACKGROUND: Hypothyroidism due to non-compliance with levothyroxine therapy (pseudomalabsorption) is rare. The diagnosis is considered in patients with persistent severe hypothyroidism despite treatment with large doses of levothyroxine. Intestinal malabsorption, drug and dietary interference with levothyroxine absorption and nephrotic syndrome should be excluded. The diagnosis of pseudomalabsorption can be demonstrated by using "an oral 1,000 µg of levothyroxine test" showing a rapid decrease in thyroid-stimulating hormone and increase in thyroxine...

BACKGROUND: Despite biochemical euthyroidism, some levothyroxine (L-T4)-treated hypothyroid patients report persisting symptoms and some of these patients are tentatively treated with a combination of L-T4 and liothyronine (L-T3). Combination therapy and the appropriate choice of blood tests to monitor treatment are highly debated among specialists and patients. AIM: To evaluate whether measuring serum triiodothyronine (S-T3) at baseline or during combination therapy can be used as an indicator of a positive effect from L-T4/L-T3 combination therapy...

INTRODUCTION: Patiromer is a potassium-binding polymer that is not systemically absorbed; however, it may bind coadministered oral drugs in the gastrointestinal tract, potentially reducing their absorption. METHODS: Twelve randomized, open-label, 3-period, 3-sequence crossover studies were conducted in healthy volunteers to evaluate the effect of patiromer (perpetrator drug) on absorption and single-dose pharmacokinetics (PK) of drugs (victims) that might be commonly used with patiromer...

We analyzed the relation of pretreatment anthropometric measures and serum thyrotropin (TSH) with the levothyroxine requirement. Children (3-18 years) brought to endocrine clinic with newly diagnosed acquired primary hypothyroidism were enrolled consecutively and prospectively with follow-up (July 2014 to April 2016). Children were started on levothyroxine, and dose was adjusted at regular intervals until achieved euthyroidism (serum TSH 0.4 to 4.5 mIU/L). The relationship of age, gender, height, weight, and serum TSH with levothyroxine dose was analyzed by univariate and multivariate regression analysis...

OBJECTIVES: The recommended starting dose of levothyroxine (LT4) in primary hypothyroidism is 1.6 μg/kg body weight and is based on presumption of minimal residual thyroid function in autoimmune hypothyroidism. This study aimed at finding the range and determining factors for LT4 dose in long-standing hypothyroidism. METHODS: A cross-sectional study of individuals with primary autoimmune hypothyroidism on LT4 replacement was done between March 2015 and January 2016...

Thyroid hormone plays an important role in brain development and adult brain function, and may influence neuronal recovery after Traumatic Brain Injury (TBI). We utilized both animal and cell culture models to determine the effects of thyroid hormone treatment, post TBI or during hypoxia, on genes important for neuronal survival and neurogenesis. We show that TBI in rats is associated with a reduction in serum thyroxine (T4) and triiodothyronine (T3). A single dose of levothyroxine (T4), one hour after injury, increased serum T4 and normalized serum T3 levels...
