Insights from a Prospective Follow-up of Thyroid Function and Autoimmunity among COVID-19 Survivors.

Endocrinol Metab (Seoul) 2021 Jun 8. Epub 2021 Jun 8.

Department of Medicine, The University of Hong Kong, Queen Mary Hospital, Hong Kong, China.

Background: The occurrence of Graves' disease and Hashimoto thyroiditis after coronavirus disease 2019 (COVID-19) raised concerns that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) may trigger thyroid autoimmunity. We aimed to address the current uncertainties regarding incident thyroid dysfunction and autoimmunity among COVID-19 survivors.

Methods: We included consecutive adult COVID-19 patients without known thyroid disorders, who were admitted to Queen Mary Hospital from July 21 to September 21, 2020 and had serum levels of thyroid-stimulating hormone, free thyroxine, free triiodothyronine (fT3), and anti-thyroid antibodies measured both on admission and at 3 months.

Thyroid dysfunction in COVID-19 patients.

J Endocrinol Invest 2021 Jun 8. Epub 2021 Jun 8.

Endocrinology Unit, Department of Oncology and Medical Specialities, A.O. San Camillo Forlanini, Rome, Italy.

Purpose: "Non thyroidal illness syndrome" (NTIS) or "euthyroid sick syndrome" (ESS) is a possible biochemical finding in euthyroid patients with severe diseases. It is characterized by a reduction of serum T (fT3), sometimes followed by reduction of serum T (fT4). The relationship between thyroid hormones levels and mortality is well known and different studies showed a direct association between NTIS and mortality. Read More

An update on non-thyroidal illness syndrome.

E Fliers A Boelen

J Endocrinol Invest 2020 Dec 15. Epub 2020 Dec 15.

Endocrine Laboratory, Department of Clinical Chemistry, Amsterdam Gastroenterology Endocrinology and Metabolism, Amsterdam UMC, University of Amsterdam, 1105 AZ, Amsterdam, The Netherlands.

The non-thyroidal illness syndrome (NTIS) was first reported in the 1970s as a remarkable ensemble of changes in serum TH (TH) concentrations occurring in probably any severe illness. Ever since, NTIS has remained an intriguing phenomenon not only because of the robustness of the decrease in serum triiodothyronine (T3), but also by its clear correlation with morbidity and mortality. In recent years, it has become clear that (parenteral) feeding in patients with critical illness should be taken into account as a major determinant not only of NTIS but also of clinical outcome.

Clinical and laboratory aspects of 3,3',5'-triiodothyronine (reverse T3).

Ann Clin Biochem 2021 01 4;58(1):29-37. Epub 2020 Nov 4.

Blood Sciences, Cambridge University Hospitals NHS Foundation Trust, Addenbrooke's Hospital, Cambridge, UK.

Reverse T3 (3,3',5'-triiodothyronine or rT3) is the third most abundant iodothyronine circulating in human blood and is produced by the inner ring deiodination of the pro-hormone thyroxine (T4). Unlike the more abundant and active metabolite T3, the measurement of serum rT3 is yet to find a routine clinical application. As rT3 binds weakly to the T3 thyroid nuclear hormone receptors, it is thought to represent an inactive end-product of thyroid hormone metabolism, diverting T4 away from T3 production. Read More

College of Veterinary Medicine, Cornell University, Ithaca, New York, USA.

Background: In cats, nonthyroidal illness affects serum thyroid hormone concentrations. Serum thyroxine (T ) and triiodothyronine (T ) concentrations commonly decrease, whereas free T (fT ) concentrations vary unpredictably. Limited information exists regarding effects on serum thyrotropin (thyroid-stimulating hormone [TSH]) concentrations in cats with nonthyroidal illness syndrome (NTIS). Read More

Severe hyperthyroidism without symptoms due to nonthyroidal illness in a child with acute hepatitis: case report and literature review.

Ann N Y Acad Sci 2021 03 23;1487(1):5-11. Epub 2020 Sep 23.

Division of Pediatric Endocrinology, Rutgers-Robert Wood Johnson Medical School, New Brunswick, New Jersey.

While liver enzyme changes are frequently reported in hyperthyroidism, liver dysfunction itself can lead to alterations in thyroid hormone metabolism. However, the exact relationship between hyperthyroidism and liver dysfunction is unclear. We report an 11-year-old boy presenting with acute hepatitis of unknown etiology, who was incidentally found to have asymptomatic biochemical hyperthyroidism. Read More

Prognostic Value of Thyroid Hormone FT3 in General Patients Admitted to the Intensive Care Unit.

Biomed Res Int 2020 12;2020:6329548. Epub 2020 Jul 12.

Department of Endocrinology, The Third Hospital of Hebei Medical University, Shijiazhuang 050051, China.

Low plasma triiodothyronine (T3) concentration indicates nonthyroidal illness syndrome (NTIS), which might be associated with a poor outcome in patients in the intensive care unit (ICU). This study evaluated the relationship between NTIS and prognostic indicators in patients admitted to the ICU and examined the fT3 cut-off points that could be associated with 28-day mortality. This prospective observational study included patients admitted to the ICU of The Third Hospital of Hebei Medical University from February to November 2018. Read More
