Adult and neonate TSH blood spot reference intervals.

Ann Clin Biochem 2022 Jun 24:45632221112654. Epub 2022 Jun 24.

Blood Sciences3237Epsom and Saint Helier University Hospitals NHS Trust.

Background: Neonatal congenital hypothyroidism screening is performed by measuring thyroid-stimulating hormone (TSH) in a dried blood spot (DBS) sample, whereas acquired hypothyroidism uses serum TSH. There is no established DBS TSH reference interval, but knowing this is useful, as some patients cannot tolerate venepuncture, so DBS collection is seen as an acceptable alternative. The aim of this study was to establish DBS TSH reference intervals in adults and neonates (day 5-8), and determine the relationship between serum and DBS TSH. Read More

Radioiodine treatment of hyperthyroidism in cats: results of 165 cats treated by an individualised dosing algorithm in Spain.

J Feline Med Surg 2022 Jun 24:1098612X221104743. Epub 2022 Jun 24.

Animal Endocrine Clinic, New York, NY, USA.

Objectives: Although radioiodine (I) is the treatment of choice for feline hyperthyroidism, I-dosing protocols commonly induce iatrogenic hypothyroidism and expose azotaemia. A recently reported patient-specific I dosing algorithm minimised the risk of I-induced hypothyroidism and azotaemia, while maintaining high cure rates. The aim of the study was to report results of I treatment in a European population of hyperthyroid cats using this patient-specific dosing algorithm. Read More

Pharmacokinetics and Clinical Implications of Two Non-Tablet Oral Formulations of L-Thyroxine in Patients with Hypothyroidism.

J Clin Med 2022 Jun 16;11(12). Epub 2022 Jun 16.

Assistance Publique-Hôpitaux de Paris Nord, Département Médico-Universitaire (DMU) INVICTUS, Département de Médecine Interne, Hôpital Lariboisière, INSERM UMRS-1144, Université de Paris Cité, 75010 Paris, France.

Background: Increased knowledge of the pharmacokinetic characteristics of orally administered levothyroxine (L-T) has improved individualization of dosing regimens. However, up to 40-45% of patients, depending on the leading cause of hypothyroidism, are still over- or, more often, undertreated. Unintentional non-adherence to L-T replacement therapy includes all situations of unintended drug-drug and drug-food interactions as well as fasting conditions that are not necessarily respected by patients.

J Clin Med 2022 Jun 15;11(12). Epub 2022 Jun 15.

Laboratorio de Neurociencias, Subdirección de Medicina Experimental, Instituto Nacional de Pediatría, Ciudad de Mexico 04530, Mexico.

Eighty-five percent of the studies of patients with congenital hypothyroidism (CH) treated with Levothyroxine (L-T) report neuropsychological sequelae throughout life. In neonates and infants, there is a deficit in sensorimotor skills (impaired balance). In preschool and elementary school children and adolescents, there are alterations in intellectual quotient (low scores), language (delayed phonological acquisition), memory (visual, verbal, visuospatial, visuoconstructive, autobiographical, and semantic), sensorimotor skills (impaired fine and gross motor control), and visuoconstructive-visuospatial domain (low scores in spatial location, block design, and object assembly).

The Clinical Relevance of Hypothyroidism in Patients with Solid Non-Thyroid Cancer: A Tantalizing Conundrum.

J Clin Med 2022 Jun 14;11(12). Epub 2022 Jun 14.

Department of Pharmacology-Clinical Pharmacology Unit, Faculty of Medicine, National and Kapodistrian University of Athens, 75 Mikras Asias Str., Goudi, 11527 Athens, Greece.

Hypothyroidism in patients with solid non-thyroid cancer is a tantalizing entity, integrating an intriguing thyroid hormones (THs)-cancer association with the complexity of hypothyroidism itself. The present narrative review provides a comprehensive overview of the clinical relevance of hypothyroidism in solid non-thyroid cancer. Hypothyroidism in patients with solid non-thyroid cancer is reminiscent of hypothyroidism in the general population, yet also poses distinct challenges due to the dual role of THs in cancer: promoting versus inhibitory.

Kidney disease and thyroid dysfunction: the chicken or egg problem.

Pediatr Nephrol 2022 Jun 23. Epub 2022 Jun 23.

Department of Nephrology, Klinikum Stuttgart - Katharinenhospital, Stuttgart, Germany.

Patients with non-dialysis-dependant chronic kidney disease (NDD-CKD) and dialysis-dependant chronic kidney disease (DD-CKD) frequently also suffer from thyroid disorders, especially hypothyroidism which is found two to five times more often among them compared to the general population. Emerging research has illustrated the potential prognostic implications of this association as NDD-CKD and DD-CKD patients with hypothyroidism have been shown to have higher mortality rates, and treatment of subclinical hypothyroidism in NDD-CKD patients has been reported to attenuate the decline of glomerular filtration rate over time. This review illustrates the bidirectional, multi-layered interplay between the kidneys and the thyroid gland explaining how pathologies in one organ will affect the other and vice versa. Read More

Changes in Thyroid Metabolites after Liothyronine Administration: A Secondary Analysis of Two Clinical Trials That Incorporated Pharmacokinetic Data.

Metabolites 2022 May 24;12(6). Epub 2022 May 24.

Department of Medicine, Division of Endocrinology, Georgetown University, Washington, DC 20007, USA.

We examined relationships between thyroid hormone (TH) metabolites in humans by measuring 3,5-diiodothyronine (3,5-T2) and 3-iodothyronamine (3-T1AM) levels after liothyronine administration. In secondary analyses, we measured 3,5-T2 and 3-T1AM concentrations in stored samples from two clinical trials. In 12 healthy volunteers, THs and metabolites were documented for 96 h after a single dose of 50 mcg liothyronine. Read More

COVID-19 and thyroid function: A bi-directional two-sample Mendelian randomization study.

Thyroid 2022 Jun 23. Epub 2022 Jun 23.

The University of Hong Kong, 25809, Department of Pharmacology and Pharmacy, Hong Kong, Hong Kong;

Background: Thyroid dysfunction has been observed among some patients with COVID-19. It is unclear whether SARS-CoV-2 infection (or its severity) leads to the development of thyroid dysfunction, or vice versa. In this study, we examined the bi-directional causal relationship between host genetic liability to three COVID-19 phenotypes (including SARS-CoV-2 infection, hospitalized and severe COVID-19) and three thyroid dysfunction traits [including hyperthyroidism, hypothyroidism, and autoimmune thyroid disease (AITD)] and three continuous traits of thyroid hormones [including thyroid-stimulating hormone (TSH) and free thyroxine (FT4) within reference range, and TSH in full range].

Koshi Hashimoto

Endocr J 2022 Jun 22. Epub 2022 Jun 22.

Department of Diabetes, Endocrinology, and Hematology, Dokkyo Medical University Saitama Medical Center, Saitama 343-8555, Japan.

Subclinical thyroid dysfunction is defined by serum thyroid-stimulating hormone (TSH) levels either greater or less than the reference range with normal thyroxine (T4) concentrations, and consists of subclinical hypothyroidism (SCH) and subclinical hyperthyroidism (SCHyper). For the proper diagnosis of SCH, it is most important to be able to correctly evaluate the serum TSH levels, which have numerous unique characteristics. We also need to be versed in TSH harmonization, which was recently launched world-wide. Read More

Clin Exp Hypertens 2022 Jun 20:1-9. Epub 2022 Jun 20.

Student Research Committee Jiroft University of Medical Sciences, Jiroft, Iran.

Hypothyroidism disturbs redox homeostasis and takes part in cardiovascular system dysfunction. Considering antioxidant and cardio-protective effects of PPAR-γ agonists including pioglitazone (POG) and rosiglitazone (RSG), the present study was aimed to determine the effect of POG or RSG on oxidants and antioxidants indexes in the heart and aorta tissues of Propylthiouracil (PTU)-induced hypothyroid rats.

Materials And Methods: The animals were divided into six groups: (1) Control; (2) propylthiouracil (PTU), (3) PTU-POG 10, (4) PTU-POG 20, (5) PTU-RSG 2, and (6) PTU-RSG 4. Read More
