Breast cancer immunotherapy: a comprehensive review.

Cancer remains a major health problem despite numerous new medical interventions that have been introduced in recent years. One of the major choices for cancer therapy is so-called adoptive cell therapy (ACT). ACT can be performed using both innate immune cells, including dendritic cells (DCs), natural killer (NK) cells, and γδ T cells and acquired immune T cells.

Relationship between Clinical and Immunological Features of Thyroid Autoimmunity and Ophthalmopathy during Pregnancy.

Problem. Clinical features of Graves' hyperthyroidism (GH) generally improve during pregnancy and rebound in the postpartum period. It is unclear whether the ophthalmopathy that is associated with GH and, less often, Hashimoto's thyroiditis (HT) changes in parallel with the thyroid associated antibody reactions and clinical features or runs a different course.

Does autoimmunity against thyroglobulin play a role in the pathogenesis of Graves' ophthalmopathy: a review.

While most authors believe that autoimmunity against the TSH receptor expressed in the orbital connective tissue cells is the main reaction that leads to the development of ophthalmopathy in patients with Graves' hyperthyroidism, an older hypothesis that deserves fresh consideration is based on the notion that thyroglobulin (Tg) in the thyroid gland passes in a retrograde fashion to the orbit where it is recognized by Tg autoantibodies, leading to inflammation. Here, we review new evidence that supports a role of Tg and propose a new hypothesis based on the notion that Tg is targeted in the orbit leading to a complex cascade of reactions that leads to Graves' ophthalmopathy.

Novel single-nucleotide polymorphisms in the calsequestrin-1 gene are associated with Graves' ophthalmopathy and Hashimoto's thyroiditis.

Background: The eye disorder associated with Graves' disease, called Graves' ophthalmopathy (GO), greatly reduces the quality of life in affected patients. Expression of the calsequestrin (CASQ1) protein in thyroid tissue may be the trigger for the development of eye muscle damage in patients with GO. We determined the prevalence of rs74123279, rs3747673, and rs2275703 single-nucleotide polymorphism (SNPs) in patients with autoimmune thyroid disorders, GO, Graves' hyperthyroidism (GH), or Hashimoto's thyroiditis (HT) and control subjects with no personal or family history of autoimmune thyroid disorders.

Thyroid-stimulating immunoglobulins as measured in a reporter bioassay are not detected in patients with Hashimoto's thyroiditis and ophthalmopathy or isolated upper eyelid retraction.

Although ophthalmopathy is mainly associated with Graves' hyperthyroidism, milder eye changes are also found in about 25% of patients with Hashimoto's thyroiditis (HT). The recent finding of negative thyrotropin receptor (TSHR) antibodies, as measured in the Thyretain™ thyroid-stimulating immunoglobulin (TSI) reporter bioassay, in patients with euthyroid Graves' disease raises the possibility that TSHR antibodies are not the cause of ophthalmopathy in all situations. Here, we have tested serum from patients with HT with and without ophthalmopathy or isolated upper eyelid retraction (UER) for TSHR antibodies, using the TSI reporter bioassay and collagen XIII as a marker of autoimmunity against the orbital fibroblast.

Thyroid function. Pathogenesis of Graves ophthalmopathy--a role for TSH-R?

A new study highlights the complexities of anti-TSH-receptor antibody function and the differences between adult and paediatric patients with Graves disease, adding to the controversy regarding the possible role of these antibodies in the development of ophthalmopathy.

Relationship between thyroid dysfunction and chronic kidney disease in community-dwelling older adults.

Objectives: Renal function has been shown to be influenced by thyroid status in animal models and human studies. We aimed to assess the cross-sectional association between thyroid hormones and function with prevalence of chronic kidney diseases (CKD) in older adults.

Study Design: 1571 Blue Mountains Eye Study participants aged ≥ 60 years were analyzed in 2002-4.

Long-term follow-up of seven patients with ophthalmopathy not associated with thyroid autoimmunity: heterogeneity of autoimmune ophthalmopathy.

Background: Ophthalmopathy is the most common extrathyroidal manifestation of Graves' disease. However, in approximately 5% of cases this autoimmune eye disorder occurs in the apparent absence of Graves' hyperthyroidism: the so-called euthyroid Graves' disease (EGD).

Methods: Seven patients with EGD were followed for evidence of thyroid and orbital autoimmunity, for up to 10 years.

Eye findings and immunological markers in probands and their euthyroid relatives from a single family with multiple cases of thyroid autoimmunity.

Background: Ophthalmopathy is a common manifestation of Graves' disease (GD) occurring in up to 50% of patients. Mild eye signs are also common in patients with Hashimoto's thyroiditis. Whilst a genetic predisposition to GD has been demonstrated this is not the case for the ophthalmopathy which often runs a separate course.

Targeting the thyrotropin receptor in thyroid disease.

Introduction: The thyrotropin receptor (TSHR) is essential for thyroid growth and for the production of thyroid hormones. It is unique among the glycoprotein hormone receptors, in that some of the TSHRs undergo cleavage and shedding of the alpha subunit.

Areas Covered: This review discusses the structure and function of the TSHR, followed by an evaluation of its role in thyroid disease.

Determinants of extraocular muscle volume in patients with graves' disease.

Background. To examine factors contributing to extraocular muscle (EOM) volume enlargement in patients with Graves' hyperthyroidism. Methods.

[Pathogenesis of thyroid eye disease - does autoimmunity against the TSH receptor explain all cases?].

Thyroid associated ophthalmopathy, or thyroid eye disease (TED), is a complex inflammatory disorder of the eye that, as its name implies, is usually associated with thyroid disease. Clinical observation supports the existence of three main TED subtypes, namely ocular myopathy, congestive myopathy, and mixed congestive and myopathic ophthalmopathy. Although the precise pathophysiology of TED remains unclear, it is likely to reflect an autoimmune reaction involving sensitised T lymphocytes and autoantibodies directed against a specific orbital or thyroid-and-orbital shared antigen(s).

Time course of Graves' ophthalmopathy after total thyroidectomy alone or followed by radioiodine therapy: a 2-year longitudinal study.

The findings in hyperthyroid patients with Graves' orbitopathy (GO) of antibodies against antigens shared between the thyroid and orbit, such as the TSH-receptor (TRAb) and a novel protein G2s (G2sAb), suggested a possible common therapeutic strategy. However, the gold therapeutic standard for hyperthyrodism in these patients remains still unsettled and is mainly based on personal experience. Studies on the effect of total thyroidectomy (TT) alone or followed by radioiodine ablation (RAI) of thyroid remnants showed often conflicting results.

Delayed-onset hypoparathyroidism in an adolescent with chromosome 22Q11 deletion syndrome.

Objective: To describe the first case of established chromosome 22q11 deletion syndrome with late onset presentation of hypocalcemia secondary to hypoparathyroidism.

Methods: We present the history, clinical and laboratory investigations, and management of a 17-year-old adolescent boy who presented with 3 separate seizures secondary to hypocalcemia. This patient had an established diagnosis of chromosome 22q11 deletion syndrome at the time of the seizure presentations, but had previously normal calcium levels.

Current concepts in graves' disease.

Graves' disease is the most common cause of hyperthyroidism in the developed world. It is caused by an immune defect in genetically susceptible individuals in whom the production of unique antibodies results in thyroid hormone excess and glandular hyperplasia. When unrecognized, Graves' disease impacts negatively on quality of life and poses serious risks of psychosis, tachyarrhythmia and cardiac failure.

Remission of Hashimoto's thyroiditis in a twelve-year-old girl with thyroid changes documented by ultrasonography.

Background: Although it is known that Hashimoto's thyroiditis in children and adolescents can go into long-term remission, and that treatment with thyroxine (T4) may not be necessary, it is difficult to quantify changes in the degree of autoimmune destruction of the thyroid. Here we report a patient in whom there was a relationship between functional and anatomical changes as assessed by hormone measurements and ultrasonography.

Summary: The patient was a 12-year-old girl with Hashimoto's thyroiditis who was initially euthyroid and later treated with 50 µg levo-T4 when her free T4 (fT4) had declined from 17 to 7 pmol/L (normal range, 8-22 pmol/L).

Epitopes, immunoglobulin classes and immunoglobulin G subclasses of calsequestrin antibodies in patients with thyroid eye disease.

A number of serum autoantibodies are associated with thyroid eye disease (TED), including those reactive against the calcium binding protein calsequestrin (CASQ). There are two isoforms of CASQ namely; CASQ1, found in skeletal, including extra ocular, muscle, and CASQ2, found in cardiac muscle. We determined (i) the reactivity profiles of CASQ1 and CASQ2 antibodies and (ii) the immunoglobulin (Ig) classes and IgG subclasses of CASQ1 antibodies, using enzyme-linked immunosorbent assay.

Pathogenesis of thyroid-associated ophthalmopathy: does autoimmunity against calsequestrin and collagen XIII play a role?

Thyroid-associated ophthalmopathy (TAO), or thyroid eye disease, is a complex inflammatory disorder of the eye that, as its name implies, is associated with thyroid disease. TAO can be divided into three subtypes: ocular myopathy, congestive myopathy and mixed congestive and myopathic ophthalmopathy. Although the precise pathophysiology of TAO remains unclear it is likely to reflect an autoimmune reaction involving sensitized T-cells and autoantibodies directed against a thyroid and orbital tissue shared antigen.

Association between radioiodine therapy for Graves' hyperthyroidism and thyroid-associated ophthalmopathy.

To investigate the role of radioactive iodine (RAI) in the onset and progression of thyroid-associated ophthalmopathy (TAO). Forty-six Graves' disease patients with mild or no ophthalmopathy were prospectively treated with carbimazole (CBZ) (n = 22) or RAI (n = 24). Treatment effects were evaluated clinically over 12 months, and with orbital MRI-measured extra-ocular muscle (EOM) volumes at baseline and at 6 months.

Eye and eyelid abnormalities are common in patients with Hashimoto's thyroiditis.

Background: Overt ophthalmopathy is presumed to be uncommon in patients with Hashimoto's thyroiditis compared to Graves' disease, where significant eye changes are found in approximately 40% of patients. On the other hand, when observing, more subtle eye changes, particularly upper eyelid retraction (UER) and mild inflammatory signs, may be common in patients with Hashimoto's thyroiditis.

Methods: We have determined the prevalence and characteristics of eye signs in recently diagnosed patients with Hashimoto's thyroiditis studied prospectively since 2004 till date in Sydney (Australia).

The cardiac calsequestrin gene (CASQ2) is up-regulated in the thyroid in patients with Graves' ophthalmopathy--support for a role of autoimmunity against calsequestrin as the triggering event.

Background: Graves' Ophthalmopathy (GO) is a complex eye and orbital disorder that is uniquely linked to Graves' Hyperthyroidism (GH) and has traditionally been considered a cross-reactive immune response against the thyroid stimulating hormone receptor (TSHR) in orbital tissue. However, because there is no direct evidence, such as specific TSHR antibodies or T lymphocytes targeting the orbital tissues in patients with GO compared to those without eye disease, it is important to consider alternative hypotheses for the pathogenesis of GO. The aim of this study was to identify differentially expressed genes within the thyroid of patients with GO and GH as a possible explanation for a thyroid initiated orbital autoimmunity.
