Hashimotos pregnancy thyroiditis-Hashimoto's Thyroiditis and Pregnancy - Dr. Izabella Wentz

Expert resources to keep you informed about your thyroid health. Fortunately, most thyroid problems that affect pregnancy are easily treated. The difficulty lies in recognizing a thyroid problem during a time when some of the chief complaints — fatigue, constipation and heat intolerance — can be either the normal side effects of pregnancy or signals that something is wrong with the thyroid. Although detecting a thyroid problem is important, it is equally necessary for those already diagnosed with a condition to have the thyroid checked if they are planning to become pregnant or are pregnant. Thyroid hormone is necessary for normal brain development.

The following information may help to address your question: Can Hashimoto's syndrome cause problems during pregnancy?

Hashimoto's syndrome that is untreated or poorly treated can cause problems for both a pregnant woman and a developing fetus. It is recommended that affected women plan their pregnancies and make sure that thyroid function is well-controlled before becoming pregnant.

Women with Hashimoto's syndrome should consult with their health care providers prior to pregnancy. A developing fetus' brain and nervous system need thyroid hormone to develop normally. Women with Hashimoto's syndrome may need to see their obstetrician or perinatologist, and an endocrinologist. The goal of treatment is to normalize maternal levels of thyroid hormones. Thyroid hormone replacement using synthetic thyroxine such as levothyroxine is both safe and necessary for the health of the mother and developing fetus.

Women with Hashimoto's syndrome who are planning to become pregnant should speak with their health care provider prior to pregnancy to make sure their hypothyroidism is corrected.

Women who are being treated usually need a higher dose to maintain normal thyroid function during the pregnancy, and there are specific ranges of ideal hormone levels for each trimester of pregnancy. Therefore, it is recommended that thyroid function be checked often during pregnancy so adjustments to the dosage can be made.

During pregnancy, the body needs higher amounts of some nutrients to support the health of both the mother and fetus. In addition to making sure thyroid hormone levels are within the normal range, it is recommended that pregnant women maintain a balanced diet and take prenatal vitamins.

Affected women should also speak with their health care provider about their intake of iodine, which is necessary for thyroid health. The thyroid uses iodine to make thyroid hormone, so iodine is particularly important for a pregnant woman. The fetus only gets iodine from the mother's diet, so women need more iodine during pregnancy. However, people with an autoimmune thyroid disease may be sensitive to harmful side effects from iodine.

Taking iodine drops or eating foods containing large amounts of iodine such as seaweed, dulse, or kelp may worsen hypothyroidism. Changes in diet and the use of dietary supplements especially during pregnancy should always be discussed with a health care provider to make sure any changes or additions to the diet are safe for both the mother and developing fetus. While there is some literature that discusses complementary and alternative therapies for thyroiditis in general, we are not aware of therapies specific to pregnant women.

Alternative therapies may help when used along with medications prescribed by your doctor, but it is strongly recommended that affected people first discuss with their doctor any alternative therapies they are considering especially before or during pregnancy. Some therapies and supplements can interfere with conventional medications or affect other processes in the body.

The thyroid gland produces, secrets, and stores two related hormones, thyroxine T4 and triiodothyronine T3 , which play a critical role in thermogenic and metabolic homeostasis.

T4 and T3 are normally synthesized and released in response to a combined hypothalamic pituitary signal mediated by thyroid stimulating hormone TSH from the anterior pituitary and thyrotropin releasing hormone from the hypothalamus.

There is a negative feedback from thyroid hormone concentration, primarily T3, to TSH production causing total T4, total T3, free T4, and free T3 concentrations to move in opposition to TSH concentration.

Hypothyroidism is a condition in which the thyroid gland is functionally inadequate. In hypothyroid thyroiditis the functional inadequacy is related to inflammation.

In response to the decreased thyroid hormone production by the thyroid gland, the anterior pituitary gland increases its production of TSH. This can cause the thyroid to enlarge. Such an enlargement is known as a goiter. Speculation about the trigger includes trauma; environmental exposures, such as cigarette smoke; or a genetic flaw. The incidence of the disease is high in the Japanese population, most likely as a result of genetic factors and a diet high in iodine.

If symptoms do develop, they are either related to the increased pressure in the neck caused by the goiter or the usual symptoms of hypothyroidism, which include fatigue, cold intolerance, weight gain, depression, and dry skin. The exact cause of postpartum dysfunction is unknown. However, it is speculated to be the result of a modification to the immune system, required during pregnancy.

Women with autoimmune disorders such as diabetes, positive antithyroid antibodies, history of previous thyroid dysfunction, history of previous PPT, or family history of thyroid dysfunction are more likely to develop PPT.

PPT often occurs in stages, with thyrotoxicosis appearing first, followed by hypothyroidism. Not all women experience both stages of PPT. Approximately one-third of women with postpartum thyroid dysfunction exhibit both stages of the disease, whereas one-third of women have only either a thyrotoxic or a hypothyroid stage. The thyrotoxic stage of PPT usually occurs months after delivery and lasts approximately months. This stage of PPT is often missed, because symptoms so closely mimic post pregnancy symptoms i.

Women will often present with the hypothyroid stage, which usually occurs months after delivery and lasts approximately months. Symptoms include fatigue, weight gain, and depression. PPT should be differentiated from lymphocytic hypophysitis. Lymphocytic hypophysitis can also occur postpartum and may cause TSH deficiency along with one or more pituitary hormones, including ACTH.

It can be distinguished from PPT by blood tests. Atrophic Thyroiditis occurs when bacteria or viruses produce inflammation in the thyroid gland.

Eventually T3 and T4 stores are depleted. Often there are no symptoms associated with atrophic hypothyroiditis for many years, and the condition remains undiagnosed until a small, palpably hard thyroid gland or abnormalities on routine thyroid function blood tests reveal the problem.

If symptoms do develop, they are the usual ambiguous symptoms of hypothyroidism i. Patients presenting in the latter stage of atrophic thyroiditis have minimal residual thyroid tissue.

In this stage, fibrosis of the thyroid gland is quite extensive. Myxedema is the result of increased dermal glycosaminoglycan content, which traps water resulting in skin thickening, pitting, and swelling. Other manifestations are:. Since atrophic thyroiditis manifests itself late in its progression, cardiac and neurological functions are often already impaired.

Carpel tunnel and other entrapment syndromes are common. However, these entrapment symptoms are not exclusive to atrophic thyroiditis. They can be seen with any autoimmune disorder. Sub-Acute Thyroiditis is a painful inflammation of the thyroid that develops suddenly in a patient who has had a viral infection. Pain radiates throughout the neck, so much so that sub-acute thyroiditis can be mistaken for a bad sore throat.

It may take several months for normal thyroid function to resume. Antithyroid antibodies are often helpful in the diagnosis of an autoimmune thyroid disorder. There are three different antithyroid antibodies: thyroperoxidase antibody TPOAb , an antibody to a follicular enzyme involved in oxidation and organification of iodine; thyroglobulin antibody TgAb , an antibody to thyroglobulin, the protein made up of the essential amino acid tyrosine to which the iodine is attached; and TSH receptor inhibiting immunoglobulin, which competes with TSH for receptor binding sites but does not activate them.

If an antithyroid antibody is present, it is often indicative of a prior attack on thyroid tissue. TSH receptor blocking antibodies are difficult to analyze and generally not available. But TSH levels without a baseline are not helpful. Reference ranges are not as tightly set as individual set points, so TSH may be normal, elevated, or depressed. In a patient with unstable thyroid status of any type, free T4 is the more reliable indicator; however, it is possible for high TSH stimulation to keep T4 levels within normal limits for quite some time.

Table I. Table II. TSH, free T4, or other analytes will not identify the cause of the hypothyroidism or the individual classification.

During pregnancy, estrogens increase TBG to times prepregnancy levels. This shifts binding such that total T3 and total T4 are approximately 1. TSH is also itself altered during pregnancy. This condition may be associated with hyperemesis. In adulthood, TSH increases in the elderly. Age related reference ranges, or at least ratio adjusted reference ranges, should be used for these analytes. Pregnancy is associated with lower albumin levels. Therefore, albumin-dependent methods are not suitable for accessing thyroid status during pregnancy.

Free T4 and TSH have reduced specificity in hospitalized patients with nonthyroid illness. Most hospitalized patients have low serum total T3 and free T3. These abnormalities are seen with both acute and chronic nonthyroid illness and are thought to be the malfunction of central inhibition of hypothalamic releasing hormone.

The National Academy of Clinical Biochemistry has published guidelines for testing of hospitalized patients with nonthyroid illness. TSH has a very short half-life of 60 minutes and is subject to circadian and diurnal variation peaking at night and reaching a nadir between 10 AM and 4 PM. T4 has a much longer half-life of 7 days, so understanding the effect of timing is crucial. For a change in analyte value to have clinical significance, the difference should take into consideration analytical and biological variabilities.

Radioactive iodine uptake is decreased in women with PPT. If there is a question about the cause of a goiter associated with hypothyroidism, a fine needle aspiration examined cytologically can confirm the presence of autoimmune thyroiditis. If replacement therapy is inadequate, the thyroid gland will continue to enlarge and cholesterol levels may increase.

Such hypercholesterolemia is generally seen as an increase in low density lipoprotein, which places the patient at greater risk of atherosclerosis. Hypothyroidism can also lead to an enlarged heart and, in rare cases, heart failure. If replacement therapy is too strong, symptoms of hyperthyroidism can develop, placing excessive strain on the heart and increasing the risk of osteoporosis. Interferences may obscure the diagnosis of hypothyroidism or complicate the monitoring of the effectiveness of thyroid replacement therapy.

Most thyroid testing is performed by either immunoassay, in which labeled and unlabeled ligands compete for a limited number of antibody sites, or immunometric assays, in which an antibody is bound to a solid surface rather than an antibody. Cross reactivity of auto-antibodies or heterophilic antibodies can affect diagnostic accuracy of competitive binding-based tests. The term heterophilic antibodies is often loosely applied to relatively weak antibodies with multiple activity sites, known as auto-antibodies, seen in auto immune disorders; broadly reactive antibodies induced by infections or exposure to therapy containing monoclonal mouse antibodies HAMA ; or human anti-animal immunoglobulins produced against well defined, specific antigens following exposure to therapeutic agents containing animal antigen or by coincidental immunization through exposure to animal antigens.

Tests in which dilutions are acceptable, such as total T4, total T3, or TSH, but not free T4 or free T3, may be checked for linearity of response to help identify heterophilic antibody interference.

Most circulating thyroid hormones are bound to protein. Only that hormone that is free is biologically active. Variations in binding protein will cause variations in concentrations of total hormones. T3 and T4 circulate in the body bound to thyroid binding globulin TBG ; transthyretin, formally known as thyroxine binding prealbumin; and serum albumin.

Physiological shifts toward greater total hormone binding will decrease available free hormone. Theoretically, free T3 and free T4 are not affected analytically by binding, but in reality, all of the free methods are binding dependent to varying degrees.

Phenytoin, carbamazepine, aspirin, and furosemide compete with thyroid hormone for protein binding sites and, thus, acutely increase free hormones and reduce total hormones. Eventually, a normal equilibrium is reestablished where free levels normalize at the expense of total levels. Heparin stimulates lipoprotein lipase, liberating free fatty acids, which inhibit total T4 protein binding and elevate free T4. Liver disease, androgens, and nephrotic syndrome decrease TBG, decreasing total thyroid hormones.

Glucocorticosteroids can lower T3 and inhibit TSH production. This interaction is of particular concern in sick, hospitalized patients in whom the elevated TSH in primary hypothyroidism may be obscured. Propanolol has an inhibitory effect on T4 to T3 conversion.

Eighty percent of T3 is produced enzymatically in nonthyroid tissue by 5 monodeiodination of T4. Methods that use fluorescent tags may be affected by the presence of fluorophore-related therapeutic or diagnostic agents. A combination of high free T4 and high TSH may be an indication of therapeutic noncompliance.

Free T4 is the short-term indicator, whereas TSH is a long-term indicator. When testing free T4, the daily dose of L-T4 should be withheld until after sampling, as free T4 is significantly increased above baseline for up to 9 hours after ingesting L-T4.

Ideally, L-T4 should be taken prior to eating, at the same time each day, and at least 4 hours apart from other medications.

Many medications and even vitamins and minerals can influence L-T4 absorption. L-T4 should not be taken with iron supplements. Patients should not switch from brand to brand of L-T4 and prescriptions should not be written generically, as doing so will allow brand to brand switches.

Although stated concentrations of L-T4 may be the same, slight variations exist between pharmaceutical manufacturers in terms of bioavailability. Also, medication storage recommendations should be scrupulously followed.
