MedicalResearch.com Interview with: Lois Donovan MD FRCPC Clinical Professor Cumming School of Medicine Division on Endocrinology and Metabolism and Department of Obstetrics and Gynecology University of Calgary MedicalResearch.com: What is the background for this study? 1) We observed in our clinical practices that minor TSH elevations in early pregnancy frequently normalized without intervention. 2) Recent randomized control trials have failed to show benefit of treating women with levothyroxine with minor TSH elevations in pregnancy  (more…)

MedicalResearch.com Interview with: Raymond S Douglas MD PhD Professor of Surgery, Division of Ophthalmology Director of the Orbital and Thyroid Eye Disease Program Cedars Sinai Medical Center MedicalResearch.com: What is the background for this study? Response: Thyroid eye disease (TED) is a debilitating disease that affects all aspects of a patients life. It is often associated with Graves' disease and thyroid abnormalities. TED causes profound bulging of the eyes impairing vision, causing eye pain and facial disfigurement. (more…)

MedicalResearch.com Interview with: Carol Chiung-Hui Peng, MD Department of Internal Medicine University of Maryland Medical Center Baltimore, MD  MedicalResearch.com: What is the background for this study? Response: In recently published meta-analyses, focusing on the general population, showed that both overt hypothyroidism and subclinical hypothyroidism were linked to higher all-cause and cardiovascular mortality. However, there is still debate and conflicting evidence on managing overt and subclinical hypothyroidism in the elderly. This study aimed to evaluate and confirm the association between hypothyroidism and mortality in the elderly population. (more…)

MedicalResearch.com Interview with: Raymond S. Douglas, MD, PhD Ophthalmology Cedars-Sinai, Los Angeles MedicalResearch.com: What is the background for this study? Response: The data presented at the American College of Rheumatology (ACR) annual meeting on November 11, 2019 are integrated, pooled efficacy data from the Phase 2 and Phase 3 clinical trials of teprotumumab for the treatment of active thyroid eye disease (TED) compared to placebo. The results support prior analyses of significant reductions in inflammation, proptosis (eye bulging) and diplopia (double vision), as well as improvements in quality of life (QoL). This presentation of the pooled analyses builds on the individual positive results of the Phase 2 and Phase 3 clinical studies.  (more…)

MedicalResearch.com Interview with: Terry Davies, MD, Professor Medicine, Endocrinology, Diabetes and Bone Disease Icahn School of Medicine at Mount Sinai Co-Director, The Thyroid Center, Mount Sinai Union Square MedicalResearch.com: What is the background for this study? What are the main findings? Response: The receptor for thyroid stimulating hormone (TSH) is the major antigen for Graves' disease and patients have unique antibodies to the TSHR which stimulate excessive thyroid hormone secretion. We have characterized a variant TSHR called v1.3 which is a splicing variant which we find expressed in thyroid, bone marrow, thymus and adipose tissue and incorporates an intronic sequence which is fully translated.  (more…)

MedicalResearch.com Interview with: Joanna Klubo-Gwiezdzinska, M.D., Ph.D., M.H.Sc. Assistant Clinical Investigator/Assistant Professor Metabolic Disease Branch/NIDDK/NIH Bethesda, MD MedicalResearch.com: What is the background for this study? What are the main findings? Response: People with intermediate- and high-risk differentiated thyroid cancer (DTC) are treated with surgical removal of the thyroid gland and radioactive iodine therapy.  After surgery and initial treatment, the thyroid hormone levothyroxine is used for long-term management not only to replace appropriate physiologic thyroid hormones post-surgery, but also to suppress thyrotropin (TSH) release from the pituitary gland at supraphysiologic doses. The current recommended American Thyroid Association TSH suppression goal in patients with a high-risk differentiated thyroid cancer presenting with distant metastases is less than 0.1mIU/ml, and between 0.1-0.5 mIU/ml for patients with intermediate-risk DTC presenting with local metastases to the neck lymph nodes. This TSH goal is much lower than physiologic TSH level, which ranges between 0.4-4.1 mIU/ml, depending on the measurement method and person’s age. TSH suppression is used because some preclinical evidence suggests that TSH can stimulate growth of cancer cells.  However, several preclinical studies show that thyroid hormones may also stimulate cancer growth. In addition, too much levothyroxine, leading to TSH suppression, may cause side effects such as abnormal heart rhythms and decreased bone mass. In this study, based on a large multicenter database analysis, we found that continuous TSH suppression with levothyroxine was not associated with better progression-free survival and overall survival in patients with either intermediate- and high-risk differentiated thyroid cancer. The patients were followed for an average of 7 years after surgical thyroid cancer removal and radioactive iodine therapy.  (more…)

MedicalResearch.com Interview with: Donald S. A. McLeod, FRACP, MPH Department of Population Health, QIMR Berghofer Medical Research Institute, Herston, Queensland, Australia MedicalResearch.com: What are the main findings of the study? Dr. McLeod: We examined the incidence of Graves’ disease and Hashimoto’s thyroiditis by race/ethnicity among U.S. active duty service personnel aged 20-54 years over a 15-year period (more than 20,000,000 person years follow-up). Cases were identified by International Classification of Diseases, Ninth Revision, Clinical Modification codes. In women, we found that Graves’ disease was almost twice as common among non-Hispanic black and Asian-Pacific Islander personnel compared with non-Hispanic white personnel.  While in men, non-Hispanic black and Asian-Pacific Islander personnel had over two-and-a-half times higher incidence compared with non-Hispanic white personnel. The opposite pattern existed for Hashimoto’s thyroiditis, with non-Hispanic white personnel having the highest incidence, and non-Hispanic black and Asian-Pacific Islander personnel the lowest incidence. Hispanic personnel did not have significantly different incidence compared to white personnel for either disorder. (more…)
