A new report by the American Autoimmune Related Diseases Association (AARDA) examining the economic impact of autoimmune disease (AD) on Americans, their families and the United States was released today at a congressional briefing as part of AARDA's 2011 National Autoimmune Diseases Awareness Month activities. Exec Director: ""While it's difficult to determine exact costs of all 100-plus autoimmune diseases, it is clear that these chronic illnesses constitute a major component of U.S. health care spending, totaling perhaps hundreds of billions of dollars in direct and indirect costs to individual patients, insurance companies and the federal government."

Study concludes that advancing age is associated with less exposure to stress, lower serum TBII and less severe clinical and biochemical Graves’ hyperthyroidism. However, if stress is not involved in lower TBII, the question arises which other mechanisms might be responsible. Most likely it is the decline in immunological response to antigens with age, a process called IMMUNOSENESCENCE. Animal models on experimental autoimmune thyroiditis have shown that lymphocytes from old mice are less effective in transferring thyroiditis than lymphocytes from young donors.

"The newly discovered compound, which is a receptor antagonist, may have the added benefit of helping those with eye problems caused by Graves' disease (Graves' ophthalmopathy)... experienced by more than 25% of people with the disease... Because the swelling in the eyes is thought to be associated with the same overstimulation of receptors caused by the same thyroid-stimulating antibodies as in the thyroid, the potential thyroid treatment may have the added benefit of treating the eye problems as well."

"One in 2 patients with Graves' disease suffers impairments to their everyday lives... Between 2006 and 2008, they surveyed 250 patients about their attitudes to life, occupational problems, and impairments to their everyday lives. Additionally, 400 physicians in private practice were asked to report on the extent and type of occupational disability. 36% of affected persons were written off sick, 5% even had to take early retirement, and 21% sought psychotherapeutic help. Among the doctors, 34% treated patients with fully impaired earning capacity."

Other self-antigens and TSI not linked to thyroid hormone production may contribute to extrathyroid inflammation in Graves disease.
All 11 of 200 (5.5 percent) TSI-positive/TRAb-negative patients had Graves orbitopathy, whereas all seven of 200 (3.5 percent) TSI-negative/TRAb-positive subjects had only Graves disease. The authors concluded that the novel Mc4/TSI is a functional indicator of Graves orbitopathy activity and severity.

...35% of pregnant women who test positive for thyroid peroxidase antibodies (TPOAb) will go on to suffer from hypothyroidism, hyperthyroidism or postpartum thyroiditis. Thyroid peroxidase is an enzyme that helps the thyroid gland utilize iodine in the production of thyroid hormones. However, approximately one in seven women have an autoimmune reaction to the enzyme, a response that entails the production of TPOAb.

Some of the most characteristic signs and symptoms of thyroid disease are those resulting from the effects of thyroid hormone on the heart and cardiovascular system. Many published reports have noted that the clinical findings resulting from excess thyroid hormone are more pronounced and prevalent than those resulting from thyroid hormone deficiency. Thus palpitations and tachycardia are reported in the majority of patients with hyperthyroidism whereas in hypothyroidism, the decrease in exercise tolerance, rise in diastolic blood pressure and decreases in cardiac contractility are much more subtle findings.

The iodothyronine deiodinases initiate or terminate thyroid hormone action and therefore are critical for the biological effects mediated by thyroid hormone. Over the years, research as focused on their role in preserving serum levels of the biologically active molecule T3 during iodine deficiency. More recently, a fascinating new role of these enzymes has been unveiled.

The major drawback of antithyroid drug treatment for hyperthyroidism is the frequent reappearance of hyperthyroidism when therapy is discontinued. However, there is, of course, no need to discontinue antithyroid drug therapy, but rather this therapy can be continued indefinitely. Except for mild side effects, serious reactions are rare, and the risks of occurrence of cardiac and bone complications are equal to or less than those of radioiodine therapy. The cost of long-term continuous antithyroid drug therapy does not exceed that of the continuous care given following radioiodine therapy. Therefore, a possible approach to the therapy of hyperthyroidism may be to control the disease, for a lifetime, with antithyroid drugs. The remarkable lack of MMI side effects and the apparent high treatment compliance in this study prompt the adoption of an alternative approach such as this.

Effects of evening vs morning thyroxine ingestion on serum thyroid hormone profiles in hypothyroid patients. Conclusions: l-thyroxine taken at bedtime by patients with primary hypothyroidism is associated with higher thyroid hormone concentrations and lower TSH concentrations compared to the samel-thyroxine dose taken in the morning. At the same time, the circadian TSH rhythm stays intact. Our findings are best explained by a better gastrointestinal uptake ofl-thyroxine during the night.

Graves’ hyperthyroidism, an organ-specific autoimmune disease mediated by stimulatory thyrotropin receptor (TSHR) autoantibodies, has been considered a Th2-dominant disease. However, recent data with mouse Graves’ models are conflicting. For example, we recently demonstrated that injection of BALB/c mice with adenovirus coding the TSHR induced Graves’ hyperthyroidism characterized by mixed Th1 and Th2 immune responses against the TSHR, and that transient coexpression of the Th2 cytokine IL-4 by adenovirus skewed Ag-specific immune response toward Th2 and suppressed disease induction.

Researchers Discover Connection Between Allergic Diseases And Autoimmune Diseases.
In all of these diseases, the underlying problem is similar--the body's immune system (including B and/or T immune cells) becomes misdirected, attacking the very organs it was designed to protect. The study implies that allergic and inflammatory diseases may actually trigger autoimmune diseases by relaxing the controls that normally eliminate newly produced, self-reactive B cells.

In contrast, the frequency of the CC genotype was higher in patients with intractable GD than in patients with GD in remission. In conclusion, the +869T/C polymorphism in the TGF-β1 gene is associated with the severity and intractability of autoimmune thyroid disease.

Thyrotoxic hypokalemic periodic paralysis (THPP) is a complication of hyperthyroidism that is mostly diagnosed in Asian populations; consequently, it can be difficult to recognize in western populations. THPP represents an endocrine emergency that can result in respiratory insufficiency, cardiac arrhythmias, and death. Its differential diagnosis from the other more common forms of hypokalemic paralysis is important to avoid inappropriate therapy.

Gradual disappearance of antibodies suggests that extrathyroidal
tissues contribute to antibody production but
that continued antibody production depends on persistence
of thyroid antigens.

By Raphael Kellman, MD: Fatigue, weight gain, insulin resistance, depression, and dementia are all associated with the degenerative aspects of aging. Yet many of these symptoms may actually be caused by hypothyroidism, which is often overlooked and misdiagnosed.

No significant differences can be traced concerning the thyroid function between different clinical subtypes of depression nor there is any correlation between specific clinical symptoms and thyroid indices....Depressed patients had higher Thyroid Binding Inhibitory Immunoglobulins (TBII), which is suggestive of the presence of an underlying autoimmune process in depression, and is independent of the clinical subtype.

Thyroid storm is a condition in which multiple organ dysfunction results from failure of the compensatory mechanisms of the body owing to excessive thyroid hormone activity induced by some factors in patients with thyrotoxicosis. While diabetic ketoacidosis (DKA) is an important trigger for thyroid storm, simultaneous development of DKA and thyroid storm is rare.

The majority of patients with Graves' disease gradually enter remission of TSH-receptor autoimmunity during medical or after surgical therapy, with no difference between the types of therapy. Remission of TSH-receptor autoimmunity after radioiodine therapy is less common.

Scientists at UCLA's Jules Stein Eye Institute and Harbor–UCLA Medical Center discovered defects in the infection-fighting T-cells of Graves' disease patients' immune systems. The study, reported March 1 in the Journal of Immunology, may deepen understanding of how the autoimmune disorder damages the body and offer a new target for treating the disfiguring disease.

April 23rd, 2009 The prevalence of benign thyroid nodules is high and there are certain ultrasound features, suggesting malignancy, that can help radiologists determine whether or not a biopsy is needed, according to a study performed at the University of California San Francisco Medical Center, San Francisco, CA.

Conclusions: The incidence of cancer in thyroid nodules < 1 cm does not appear to be lower than in larger nodules and may even be higher. Physicians should consider obtaining biopsy samples from subcentimeter hypoechoic nodules that contain microcalcification and have a relatively round shape (LA/SA < 1.5).

The authors say, "The observed association between hypothyroidism and breast cancer may be due to the biologic effect of (the thyroid hormone) T3 at the cellular level," adding that further studies of thyroid regulating hormones and intracellular iodide concentrations may "indicate areas of intervention for targeted preventive and therapeutic purposes."
