CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Abstract. We report the case of severe consumptive hypothyroidism in a 1-month-old The paraneoplastic syndrome consumptive hypothyroidism is a rare form of hypothyroidism first identified in newborns with infantile hepatic hemangiomatosis (HHE) ().The latter is a benign tumor of vascular origin affecting 4-5% of white infants. Primary hypothyroidism is the principal manifestation of hypothyroidism, but other causes include central deficiency of thyrotropin-releasing hormone or thyroid-stimulating hormone (TSH), or consumptive hypothyroidism from excessive inactivation of thyroid hormone. The dose of L-Thyroxine was increased 2-fold. A high index of suspicion is required to diagnose consumptive hypothyroidism. Introduction Infantile hepatic hemangioma with consumptive hypothyroidism is a rare condition. If, however, the TSH is low and the levels of free T4 (FT4) or free T3 (FT3) are also low or normal, these . The patient received intensive care treatment for severe heart failure. Case report A 4-month-old girl presented with diffuse hepatic hemangiomas during treatment of congenital hypothyroidism. Abstract Background Infantile hepatic haemangiomas (IHHs) produce an excess of the thyroid hormone inactivating enzyme type-3 iodothyronine deiodinase (D3), leading to rapid degradation of thyroid hormones and consumptive hypothyroidism. Hypothyroidism: Laboratory Findings. Although hypothyroidism is a frequent clinical scenario, the astute clinician must remember that hypothyroidism can often be the herald of a much more sinister diagnosis such as a GIST. The L-thyroxine replacement dose in patients with consumptive hypothyroidism is inappropriately higher than that in congenital hypothyroidism. Consumptive hypothyroidism is caused by aberrant expression of the deiodinase 3 enzyme (which inactivates thyroid hormone) in tumour tissues. Consumptive hypothyroidism is a rare form of hypothyroidism that was first reported in an infant with massive hepatic hemangiomas by Huang et al. When this exceeds the rate of synthesis of these hormones, a state of hypothyroidism ensues. We report a unique case of a 3-mo-old female with consumptive hypothyroidism and liver hemangioendothelioma who required pharmacological doses of thyroid hormones and was cured following liver transplantation. When the laboratory result for TSH is found to be elevated above the established reference interval and the free levels of T4 or T3 are low, these finding support a diagnosis of primary hypothyroidism. acquired hypothyroidism, consumptive hypothyroidism, hypothyroidism, infantile hepatic hemangiomas, type 3 iodothyronine deiodinase Search for Similar Articles You may search for similar articles that contain these same keywords or you may modify the keyword list to augment your search.

Annals of Clinical and Laboratory Science. Early recognition and treatment of these pathologies is paramount in order to minimise the risk of longterm sequelae. Other tumors may cause consumptive hypothyroidism. This case emphasizes the importance of screening for hypothyroidism in patients with neonatal hemangiomatosis. Infantile hepatic hemangiomas (IHH), particularly of the diffuse subtype can, in severe cases, be associated with hepatic and cardiac failure, compartment syndrome and consumptive hypothyroidism. . Evaluation showed hypothyroidism associated with infantile hemangioma of the liver. This often requires treatment with high doses of IV T4, with or without doses of T3 as well, until the neoplasm is treated. 5 High activity levels of D3, which catalyzes the conversion of T4 to rT3 and T3 to T2, were identified in the hemangioma specimen. can be caused by consumptive hypothyroidism due to aberrant expression of the deiodinase 3 enzyme (which inactivates thyroid hormone) can also be caused by rare genetic syndromes that lead to a congenital reduced sensitivity to thyroid hormone (for example, mutations in MCT8 , SECISBP2 , THRA , or THRB ) Consumptive hypothyroidism is a rare but important associated condition in patients with HHE.

Consumptive hypothyroidism is a rare paraneoplastic syndrome hyporhyroidism by excessive inactivation of the thyroid hormones due to increased type 3 iodothyronine deiodinase activity of tumors. Consumptive hypothyroidism is a rare condition related to massive infantile hemangiomas producing an excess of the thyroid-hormone-inactivating enzyme type 3 iodothyronine deiodinase. The tumor, a malignant solitary fibrous tumor, was excised, and was determined to be the source of ectopic D3 production. Background Infantile hepatic haemangiomas (IHHs) produce an excess of the thyroid hormone inactivating enzyme type-3 iodothyronine deiodinase (D3), leading to rapid degradation of thyroid hormones and consumptive hypothyroidism. This enzyme causes increased degradation of T4 and T3 to reverse T3 (inactive metabolite). Refractory hypothyroidism can be a clue to asymptomatic vascular tumors. She showed a hormonal pattern of central hypothyroidism. Case Report A 45dayold male patient was referred to our clinic with a diagnosis of infantile hemangiomas (IH) and jaundice (Fig. Unlike classical primary and secondary forms of hypothyroidism it doesn't result from reduced production or release of thyroid hormones from the thyroid gland but from increased degradation of thyroxine, which cannot be compensated by upregulated hormone synthesis in the thyroid. Consumptive hypothyroidism is a complication of infantile hepatic hemangioma (IHH) caused by increased expression of type-3 deiodinase enzyme in the tumor tissue. Background Infantile hepatic haemangiomas (IHHs) produce an excess of the thyroid hormone inactivating enzyme type-3 iodothyronine deiodinase (D3), leading to rapid degradation of thyroid hormones and consumptive hypothyroidism. Because his findings resolved, he was started to be followed up with propranolol . Thyroid function should not be assessed in seriously ill patients unless a strong suspicion of thyroid dysfunction. Interpretive Summary: This paper describes a new approach in the prevention of hypo- and hyperglycemia in children with Type 1 diabetes. , with several other CHS cases reported thereafter. On the other hand, it may lead to consumptive hypothyroidism, a rare syndrome caused by increased catabolism of T4 and T3 by increased type 3 iodothyronine deiodinase (D3) activity. Pr e gnancy is a phy siolog ical condition characterized by changes in thyroidal economy due to a combination of pregnancy-related fac- Hypothyroidism is the result of inadequate production of thyroid hormone or inadequate action of thyroid hormone in target tissues. 52%. The clinical features of both consumptive hypothyroidism due to BNH and simple congenital hypothyroidism are similar, and even some laboratory data are shared by both diseases, for example high TSH and low FT4 and T3 levels.

The paraneoplastic syndrome consumptive hypothyroidism is a rare form of hypothyroidism rst identied in newborns with infantile hepatic hemangiomatosis (HHE) (28). The L-thyroxine replacement dose in patients with consumptive hypothyro This consumptive hypothyroidism is likely due to overexpression of type 3 deiodinase in the endothelium of vascular tumor. Consumptive hypothyroidism is a very rare form of hypothyroidism that has been found in patients with certain types of ectopic tumors that produce type 3 deiodinase which degrades thyroid hormones. 37(3):280-284. {{configCtrl2.info.metaDescription}} This site uses cookies. This is the first adult patient identified with this condition. However, a negative neonatal thyroid screening test at birth, relatively late onset of symptoms, normal thyroid scintigraphy, elevated thyroglobulin and rT3 and a very high requirement of LT4 to achieve euthyroidism favours the diagnosis of consumptive hypothyroidism. We present an infant with IHH-related hypothyroidism, in whom treatment with propranolol led to regression of tumor and subsequent euthyroid status. The association between consumptive hypothyroidism and hepatic hemangioendothelioma (HHE) was first reported by Huang SA [3]. Consumptive hypothyroidism has also been associated with extra-hepatic HHE. Consumptive hypothyroidism develops when the rate of inactivation of thyroid hormones surpasses the rate of their production, and this may be attributed to the presence of a high level of 3 iodothyronine deiodinase in the hemangioma tissue which catalyzes the conversion of T4 to rT3 and of T3 to diiodothyronine, both of which are biologically .

We report a case of a male newborn who was evaluated due to persistent jaundice. Following joint consultation with dermatology and endocrinology she was promptly treated with oral propranolol and levothyroxine, with subsequent improvement in her clinical parameters. congenital hypothyroidism and consumptive hypothyroidism are identical. Consumptive hypothyroidism is characterized by excessive inactivation of thyroid hormone by type 3 iodothyronine deiodinase (D3). Read "Increased type 3 iodothyronine deiodinase activity in a regrown hepatic hemangioma with consumptive hypothyroidism, European Journal of Pediatrics" on DeepDyve, the largest online rental service for scholarly research with thousands of academic publications available at your fingertips. What is the Evidence? Patients have elevated serum rT3 levels as a result of increased T4 and T3 degradation by D3 (7,10). Consumptive hypothyroidism is a rare form of hypothyroidism resulting from increased production of type 3 iodothyronine deiodinase (D3) (), the major enzyme responsible for the inactivating pathway of thyroid hormone.D3 permits tissue-specific regulation of thyroid hormone signaling by converting T 4 to rT 3 as well as T 3 to diiodothyronine.The end-products of both of these conversions are . Ruppe et al 3 reported the case of a 54-year-old male with an abdominal mass and consumptive hypothyroidism. Here, we report a case of bipolar I disorder who developed symptomatic valproate-induced hypothyroidism. Euthyroidism and regression of the hepatic hemangiomas were obtained with L-thyroxin and Propranolol treatment. The latter is a Consumptive hypothyroidism is often the clinical condition that results from neoplasms producing their own selenodionases that convert T4 needed to be converted to active T3 into an active form of thyroid hormone, rT3. Consumptive hypothyroidism is characterised by low free T3 (fT3) and normal or low free T4 (fT4), despite elevated thyroid stimulating hormone (TSH) (8,9). The L-thyroxine replacement dose in patients with consumptive hypothyroidism is inappropriately higher than that in congenital hypothyroidism. Hypothyroidism is a common endocrine disease in which the thyroid gland does not produce enough thyroid hormone (triiodothyronine and/or thyroxine).Hypothyroidism has been reported in every domestic animal.Primary hypothyroidism is the most common form of hypothyroidism, but other causes include deficiency of thyrotropin-releasing hormone or deficiency of thyroid-stimulating hormone, or . Type 3 iodothyronine consumptive hypothyroidism is highly expressed in the human uteroplacental unit and in fetal epithelium. TITLE: Consumptive Hypothyroidism: T3 or Not T3, That Is the Question AUTHORS: Kevin Hess , Soraya Bascoy , James Lenhard KEYWORDS: Hypothyroidism , Consumptive Hypothyroidism , Neuroendocrine Tumors The patient became euthyroid postoperatively. Consumptive hypothyroidism has also been associated with extra-hepatic HHE. ABSTRACT: Consumptive hypothyroidism is often the clinical condition that results from neoplasms producing their own selenodionases that convert T4 needed to be converted to active T3 into an active form of thyroid hormone, rT3. D3 is the major physiologic inactivator of thyroid hormone, this selenoenzyme catalyzes the inner-ring deiodination of T(4) to reverse T(3) and T(3) to 3, 3 . We present an infant with IHH-related hypothyroidism, in whom It can be focal, multifocal, or diffuse. Remember, you can still have a thyroid physiology problem, but a healthy gland. In cases of patients requiring supranormal doses of T4, a measurement of reverse T3 should be considered to establish the diagnosis of consumptive hypothyroidism. Consumptive hypothyroidism syndrome (CHS) is an uncommon and severe form of hypothyroidism that occurs due to high levels of D3 expression by neoplastic tissues, resulting in high rates of thyroid hormone inactivation. Liver hemangioendotheliomas are capable of producing an excess of the thyroid hormone inactivating . Infantile hepatic hemangiomas (IHH) particularly the diffuse subtype, can in severe cases be associated with hepatic and cardiac failure, compartment syndrome, and consumptive hypothyroidism. Exogenous disorders are conditions that originate outside of the patient and the most common cause in the world is iodine deficiency. Consumptive hypothyroidism develops when the rate of inactivation of thyroid hormones surpasses the rate of their production, and this may be attributed to the presence of a high level of 3 iodothyronine deiodinase in the hemangioma tissue which catalyzes the conversion of T4 to rT3 and of T3 to diiodothyronine, both of which are biologically . Subsequent to this, thyroid function tests confirmed an associated but comparatively rare form of hypothyroidism, known as consumptive hypothyroidism. Consumptive Hypothyroidism.
