Abstract

At 5 years of age inappropriate thyrotropin secretion was diagnosed in a girl now 11 years old. She had clinical signs of hyperthyroidism, and circulating thyroid hormones were elevated, but the TSH-level was within normal range. There was no evidence of a pituitary tumor. Therapy with bromocriptine, dexamethasone, and D-thyroxine had no measurable effect. The treatment with methimazole led to normal levels of circulating thyroid hormones, however, the TSH-level increased and the thyroid gland became diffusely enlarged. By the administration of 3,5,3'-triiodothyroacetic acid (TRIAC) (at present 20 micrograms/kg body weight) the TSH-level was lowered and a long-term remission of hyperthyroidism was achieved.

L-thyroxin treatment in infants with hyperthyrotropinaemia: 4-year experience.

Hyperthyrotropinaemia, in which normal levels of T4 occur in association with raised thyroid stimulating hormone (TSH), is usually picked up on neonatal screening. High TSH level can continue for a long time in some of the cases. There is no consensus concerning the follow-up or treatment plan for hyperthyrotropinaemia. In this study, results of a 4-year follow-up of 36 cases who had been medically treated are discussed. Low-dose (5 microg/kg/day) L-thyroxin treatment was carried out in 36 cases that had 5 mU/l or higher TSH and showed exaggerated response to TRH test. Dose was decreased to 2-3 microg/kg/day in 24 of these patients during 6 months follow-up. The drug was stopped in three cases because of the development of biochemical hyperthyroidism. Denver developmental assessment test was applied to all cases at the end of the third year. All patients showed a normal development in relation to their age. According to our results, cases with hyperthyrotropinaemia need to be followed regularly for a long time and a need for low-dose L-thyroxin treatment may exist at ages varying from patient to patient.

Barriers in the quest for quality drug information: salutary lessons from TGA-approved sources for thyroid-related medications.

Product information (PI) for thyroid-related medications endorsed by the Therapeutic Goods Administration, as reproduced in the commonly used compilation publications June 2006 MIMS (Monthly index of medical specialties) annual, MIMS Online and the Australian prescription products guide 2006, was evaluated to see whether it reflects contemporary therapeutic practice. Compared with current medical literature, these PI-based sources provide inadequate, inaccurate or outdated therapeutic directives. Examples include: Incorrect advice that thyroxine therapy should always begin at very low dosage. Failure to recommend increased thyroxine dosage early in pregnancy (thus placing the offspring of women being treated for hypothyroidism at risk of impaired fetal brain development). Incorrect and potentially unsafe advice to treat thyrotoxicosis with stable iodide in late pregnancy. Failure to advise serial adjustment of antithyroid drug dosage until after a patient becomes euthyroid (this can result in iatrogenic thyroid dysfunction). Outdated advice that antithyroid drugs are not compatible with breastfeeding. Recent initiatives to upgrade consumer medicine information (CMI) appear to accept PI-based sources as a reliable benchmark for CMI. That inference is not warranted for thyroid-related medications. Accountability for the updating of clinical information in PI needs to be defined, and the process for updating PI may need to be modified. Quality drug information, both PI and CMI, depends on fluent, evidence-based collaboration between suppliers, regulators, prescribers, specialist clinicians and consumers.

Antithyroid drugs inhibit thyroid hormone receptor-mediated transcription.

CONTEXT: Methimazole (MMI) and propylthiouracil (PTU) are widely used as antithyroid drugs (ATDs) for the treatment of Graves' disease. Both MMI and PTU reduce thyroid hormone levels by several mechanisms, including inhibition of thyroid hormone synthesis and secretion. In addition, PTU decreases 5'-deiodination of T(4) in peripheral tissues. ATDs may also interfere with T(3) binding to nuclear thyroid hormone receptors (TRs). However, the effect of ATDs on the transcriptional activities of T(3) mediated by TRs has not been studied. OBJECTIVE: The present study was undertaken to determine whether ATDs have an effect on the gene transcription regulated by T(3) and TRs in vitro. METHODS: Transient gene expression experiments and GH secretion assays were performed. To elucidate possible mechanisms of the antagonistic action of ATDs, the interaction between TR and nuclear cofactors was examined. RESULTS: In the transient gene expression experiments, both MMI and PTU significantly suppressed transcriptional activities mediated by the TR and T(3) in a dose-dependent manner. In mammalian two-hybrid assays, both drugs recruited one of the nuclear corepressors, nuclear receptor corepressor, to the TR in the absence of T(3). In addition, PTU dissociated nuclear coactivators, such as steroid receptor coactivator-1 and glucocorticoid receptor interacting protein-1, from the TR in the presence of T(3). Finally, MMI decreased the GH release that was stimulated by T(3). CONCLUSIONS: ATDs inhibit T(3) action by recruitment of transcriptional corepressors and/or dissociation of coactivators. This is the first report to show that ATDs can modulate T(3) action at the transcriptional level.
