  • Two Cases of Armour Thyroid Interference in Thyroglobulin Monitoring for Thyroid Cancer. [Case Reports]
    Case Rep Endocrinol. 2021; 2021:1152572.Ponder M, Lamos E, Munir K
  • Thyroglobulin (Tg) monitoring is the biochemical standard for surveillance of recurrent differentiated thyroid cancer (DTC). Several assays are available to quantify Tg levels: immunometric assay (IMA), radioimmunoassay (RIA), and the newer liquid chromatography tandem mass spectrometry (LC-MS). It is well known that a number of entities can interfere with the accuracy of testing, and at this poi…
  • Drugs and Lactation Database (LactMed): Thyroid [BOOK]
    Drugs and Lactation Database (LactMed). National Library of Medicine (US): Bethesda (MD)BOOK
  • Thyroid is an animal-derived mixture of levothyroxine (T4) and liothyronine (T3), which are normal components of human milk. Limited data on exogenous replacement doses of levothyroxine during breastfeeding indicate no adverse effects in infants. If thyroid is required by the mother, it is not a reason to discontinue breastfeeding. The American Thyroid Association recommends that subclinical and …
  • Drugs and Lactation Database (LactMed): Liothyronine [BOOK]
    Drugs and Lactation Database (LactMed). National Library of Medicine (US): Bethesda (MD)BOOK
  • Liothyronine (T3) is a normal component of human milk. If replacement doses of liothyronine are required by the mother, it is not necessarily a reason to discontinue breastfeeding. However, because no information is available on the use of exogenous liothyronine during breastfeeding, an alternate drug may be preferred. The American Thyroid Association recommends that subclinical and overt hypothy…
  • Patient Experiences and Perceptions Associated with the Use of Desiccated Thyroid Extract. [Journal Article]
    Medicina (Kaunas). 2020 Apr 03; 56(4)Toloza FJK, Espinoza Suarez NR, … Brito JP
  • Background and objectives: It is unclear why many patients with hypothyroidism prefer the use of desiccated thyroid extract (DTE) as a thyroid hormone replacement formulation over levothyroxine (LT4) treatment, as recommended by clinical practice guidelines. We analyzed patient-reported information from patient online forums to better understand patient preferences for and attitudes toward the us…
  • Physician Choice of Hypothyroidism Therapy: Influence of Patient Characteristics. [Journal Article]
    Thyroid. 2018 11; 28(11):1416-1424.Jonklaas J, Tefera E, Shara N
  • CONCLUSIONS: Even with the acknowledged limitations of survey methodology, this analysis appears to show a marked increase in the willingness of physicians to prescribe combination therapy in specific circumstances. If current prescribing patterns do incorporate the use of therapies other than LT4, there is a critical need for more research into the benefits and risks of these therapies.
  • Armour® Thyroid Rage - A Dangerous Mixture. [Case Reports]
    Cureus. 2018 Apr 24; 10(4):e2523.Coutinho J, Field JB, Sule AA
  • Armour® Thyroid (Forest Pharmaceuticals, LLC; affiliate of Allergan, Dublin, Ireland) is a natural porcine derivative thyroid supplement that is frequently used without physician monitoring by health enthusiasts as a weight loss supplement. Although there are no publications associating Armour Thyroid and major coronary events, significant drug interactions may exist. A 32-year-old male with a hi…
  • The emergence of levothyroxine as a treatment for hypothyroidism. [Historical Article]
    Endocrine. 2017 Jan; 55(1):6-18.Hennessey JV
  • CONCLUSIONS: The evolution of thyroid hormone therapies has been significant over an extended period of time. Thyroid hormone replacement is very useful in the treatment of those with hypothyroidism. All of the most recent guidelines of major endocrine societies recommend levothyroxine mono-therapy for first line use in hypothyroidism.
  • Thyroxine and triiodothyronine content in commercially available thyroid health supplements. [Journal Article]
    Thyroid. 2013 Oct; 23(10):1233-7.Kang GY, Parks JR, … Bernet VJ
  • CONCLUSIONS: The majority of dietary thyroid supplements studied contained clinically relevant amounts of T4 and T3, some of which exceeded common treatment doses for hypothyroidism. These amounts of thyroid hormone, found in easily accessible dietary supplements, potentially expose patients to the risk of alterations in thyroid levels even to the point of developing iatrogenic thyrotoxicosis. The current study results emphasize the importance of patient and provider education regarding the use of dietary supplements and highlight the need for greater regulation of these products, which hold potential danger to public health.
  • Over-the-counter-drug-induced thyroid disorders. [Case Reports]
    Endocr Pract. 2013 Mar-Apr; 19(2):268-74.Hoang TD, Mai VQ, … Shakir MK
  • CONCLUSIONS: These case reports demonstrate the significant risks associated with OTC preparations containing iodine in patients predisposed to thyroid dysfunction. There is no valid reason for taking high-dose OTC iodine supplements, which have been shown to cause harm and have no known benefit.
  • Manipulating thyroid status alters endoplasmic reticulum calcium homeostasis in rat cerebellum. [Journal Article]
    Indian J Exp Biol. 2012 Jan; 50(1):7-18.Cole JT, McMullen DC, … Watson WD
  • Thyroid-related hormones regulate the efficiency and expression of sarco-endoplasmic reticulum calcium ATPases in cardiac and skeletal muscle. However, little is known about the relationship between thyroid hormones and calcium (Ca2+) homeostasis in the brain. It is hypothesized that manipulating rat thyroid hormone levels would induce significant brain Ca2+ adaptations consistent with clinical f…
  • [Histological detection of dried tiny thyroid tissue in health foods]. [Journal Article]
    Rinsho Byori. 2008 Dec; 56(12):1077-80.Ichikawa T, Kobayashi Y, Miyajima Y
  • Two patients were diagnosed as having hyperthyroidism, and both had taken the same health food. We compared three kinds of histological methods to detect thyroid gland in this health food. The first method used cytology; the second applied the cell-block method; and the last is a modification of the cell particle (CPCB) method proposed by Ushijima. It is the third method that achieved superior re…
  • Primary hypothyroidism presenting as multiple ovarian cysts in an adult woman: a case report. [Case Reports]
    Gynecol Endocrinol. 2008 Oct; 24(10):586-9.Kubota K, Itho M, … Minegishi T
  • A 21-year-old woman was referred because of abdominal pain. On physical examination, her abdomen was distended up to the umbilical region. Ultrasound and computer tomography of the abdomen revealed bilateral multiple ovarian cysts. Laboratory studies revealed increased liver function, total cholesterol and creatine phosphokinase. Further clinical investigations determined that the patient suffere…
  • Rescue from dwarfism by thyroid function compensation in rdw rats. [Journal Article]
    Exp Anim. 2005 Oct; 54(5):455-60.Furudate S, Ono M, … Kameya T
  • The rdw rat was initially reported as having hereditary dwarfism caused by pituitary dysfunction. Subsequent studies on the rdw rat, however, have demonstrated that the primary cause of rdw dwarfism is present in the thyroid gland but not in the pituitary gland. The primary cause of rdw rat disorders is a missense mutation of the thyroglobulin (Tg) gene by a one-point mutation. In the present stu…
  • Sub-laboratory hypothyroidism and the empirical use of Armour thyroid. [Case Reports]
    Altern Med Rev. 2004 Jun; 9(2):157-79.Gaby AR
  • Evidence is presented that many people have hypothyroidism undetected by conventional laboratory thyroid-function tests, and cases are reported to support the empirical use of Armour thyroid. Clinical evaluation can identify individuals with sub-laboratory hypothyroidism who are likely to benefit from thyroid-replacement therapy. In a significant proportion of cases, treatment with thyroid hormon…
  • Plummer's disease with spontaneous progression to hypothyroidism. [Case Reports]
    Ann Nucl Med. 1999 Dec; 13(6):433-5.Nakae T, Kawanaka M, … Fukuchi M
  • A case of Plummer's disease that spontaneously progressed to hypothyroidism is presented. A 49-year-old female visited our hospital because of a 3 kg decrease in body weight during the previous month and a painless nodule in the right anterior area of her neck. A diagnosis of Plummer's disease was made based on the results of thyroid function tests, thyroid scintigrams, and an ultrasonogram, but …
