Investigation of blood groups in benign thyroid diseases in Turkey.

The objective of our study is to investigate how often ABO and Rh blood groups are seen in benign thyroid diseases, especially in autoimmune-mediated thyroid diseases, and hence whether there is an association between blood groups and thyroid diseases. A total of 958 patients who were followed due to any benign thyroid disease were included in the study. The study population comprised 958 patients, 550 with Hashimoto's hypothyroidism, 160 with non-Hashimoto's hypothyroidism, 103 with iatrogenic hypothyroidism, 93 with central hypothyroidism, and 28 with Graves' and 24 with non-Graves' hyperthyroidism. Of the patients, 47.1% belonged to the O blood group, 30% to the A blood group, 15.2% to the B blood group, and 7.7% to the AB blood group while 90% were Rh-positive. The ratio of those with the O blood group was determined to be significantly higher in the Hashimoto's hypothyroidism group compared to the other disease groups. In the non-Hashimoto's hypothyroidism group, however, the ratio of the AB blood group was statistically significantly higher. While autoimmune diseases were more common in those with the O blood group, they were significantly lower in the AB blood group (p

Summary The prevalence and clinical relevance of thyroid stimulating hormone (TSH) receptor (TSHR) blocking antibodies (TBAb) in patients with autoimmune thyroid disease (AITD) was investigated. Serum TBAb were measured with a reporter gene bioassay using Chinese hamster ovary cells. Blocking activity was defined as percentage inhibition of luciferase expression relative to induction with bovine TSH alone (cut‐off 40% inhibition). All samples were measured for TSHR stimulatory antibody (TSAb) and TSHR binding inhibiting immunoglobulins (TBII). A total of 1079 unselected, consecutive patients with AITD and 302 healthy con...

Authors: Mikos H, Mikos M, Niedziela M Abstract INTRODUCTION: The aim of the study was to assess serum levels of sFasL as a marker of thyroid dysfunction in children with autoimmune thyroid disease (AITD). DESIGN: The group comprised 45 newly diagnosed children with Hashimoto's thyroiditis and Graves' disease versus euthyroid control group: 11 with hypothyroidism (10 girls and 1 boy, aged 12.2 ± 1.9 years), 19 children with hyperthyroidism (15 girls and 4 boys, aged 12.4 ± 4.9 years) and 15 healthy subjects (7 girls and 8 boys, aged 10.5 ± 4.8 years...

CONCLUSION: Diagnosis and management of fetal hyperthyroidism can be challenging. TSH receptor antibody testing should be considered in pregnant women with any history of autoimmune thyroid disease and symptoms of fetal hyperthyroidism. PMID: 27813690 [PubMed - as supplied by publisher]

By: Dr. Alan Christianson When someone you know is living with hypothyroidism, it can be tempting to think that if only the doctor would prescribe an extra helping of thyroid hormone, your friend or loved one would feel so much better and would enjoy life more. And in some cases, an extra helping might be in order. In other cases, not so much. Too much thyroid hormone can actually be dangerous, which is why doctors are loathe to bump the levothyroxin dosage up an extra 25 micrograms or so for one of their patients who's still experiencing hypothyroid symptoms. Tests always come first, and there's a good reason for that....

This study also demonstrated a greater proportion of ATD patients who demonstrated high titres (≥1:6400) of TPO compared with high titres of Tg. Although there was an association between ATD and the presence of anti-Ro/SSA and/or anti-La/SSB antibodies, the absence of sicca symptoms and negative Schirmer's tests suggest a lack of association with secondary Sjogren's syndrome. A novel association between ATD and antiphospholipid syndrome (APS) was detected in our cohort. Hence we propose that patients affected by APS be routinely screened for ATD.

Abstract Autoimmune thyroid disease is the most common organ-specific autoimmune disorder which consists of two opposing clinical syndromes, Hashimoto's thyroiditis and Graves' (hyperthyroidism) disease. Graves' disease is characterized by goiter, hyperthyroidism, and the orbital complication known as Graves' orbitopathy (GO), or thyroid eye disease. The hyperthyroidism in Graves' disease is caused by stimulation of function of thyrotropin hormone receptor (TSHR), resulting from the production of agonist antibodies to the receptor. A variety of induced mouse models of Graves' disease have been developed over the p...
