Iodinated contrast medium in patients with thyroid disorders.

[Iodinated contrast medium in patients with thyroid disorders]. Radiologe. 2019 Apr 04;: Authors: Leidig-Bruckner G Abstract BACKGROUND: Adequate intake of iodine is essential for normal thyroid function. However, sudden exposure to high amounts of iodine may cause thyroid dysfunction. AIM: The aims of this paper are to summarize the literature on the effects of iodinated contrast medium (CM) on thyroid function, the risk to develop CM-induced hyper- and hypothyroidism, and to describe procedures for clinical practice regarding diagnosis, prevention, and treatment of CM-induced hyperthyroidism. RESULTS: The occurrence of CM-induced hyperthyroidism is very rare (60 years) with autonomous thyroid and concomitant cardiac diseases are at particular risk of developing hyperthyroidism. The main focus of prevention is to identify patients at risk of developing iodine-induced hyperthyroidism and carry out further thyroid diagnostic procedures prior to CM use. In these patients, prophylaxis with perchlorate and/or thionamides is recommended or alternatively careful monitoring of the patients after use of CM. In patients with overt hyperthyroidism, the use of CM is contraindicated. Iodine-induced hypothyroidism is predominantly found in regions with sufficient iodine supply and in patients with autoimmune thyroiditis. Free iodide influences iodide uptake into the thyroid and therefore interferes with nuclear diagnostic procedures like thyroid scinti...

AbstractGraves ’ orbitopathy (GO) is the most common cause of orbital tissue inflammation, accounting for ~ 60% of all orbital inflammatory conditions in the population aged 21–60 years, and for ~ 40% in the population aged >  60 year. GO is observed in 25–30% of patients with Graves’ hyperthyroidism and more rarely in association with hypothyroid autoimmune thyroiditis. In addition, a small proportion of GO patients (1–2%) do not have a clinically overt thyroid dysfunction. Clinically, GO is characterized by pr optosis, inflammation invol...

Conclusions: Considerable intra-individual clustering occurred in the biochemical and symptomatic responses to LT4 treatment, implying statistically multileveled response groups. Unmasking individual differences in the averaged treatment response hereby highlights clinically distinguishable subgroups within an indiscriminate patient panel. This, through well-designed larger clinical trials will better target the different therapeutic needs of individual patients.

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...

ConclusionsIn our sample of 11 Caucasian patients with thyroid dysfunction related with anti-PD1, we found low frequency of ATA positive titers, comparable to other recent reports in others ethnicities, which could suggest that silent thyroiditis due to pembrolizumab or nivolumab has a different pathogenesis from the classical autoimmune spontaneous thyroiditis. Further investigations are required to completely understand the immune mechanisms involved.

We report the case of a woman with autoimmune hypothyroidism and extremely high TRAb levels, with blocking and stimulating activities (biological activities characterized with Chinese hamster ovary cells expressing TSHR). At the 22-week point of her first gestation, sonography detected fetal growth retardation and cardiac abnormalities (extreme tachycardia, right ventricular dilatation, pericardial effusion). The mother's TRAb level, assayed later, was 4030 IU/L (N

GD, and AT, can be associated with other organ specific, or systemic autoimmune diseases in the same patient. However discordant results have been reported in the literature about the possible associations. Here, we review...

I am re-posting a classic Wheat Belly Blog post from a few years ago. Despite all our discussions about thyroid issues, there continues to be an enormous information gap: undiagnosed hypothyroidism, gross mismanagement sufficient to impair weight loss and increase cardiovascular risk, dismissing the importance of iodine, and ignorance among healthcare providers. This Thyroid Tune-up is therefore an updated version of the previous post. Imagine that all the cars in your neighborhood run poorly because nobody bothers to tune-up their autos. I show you how to tune the cars and, lo and behold, 80% of the cars now run great.&nb...
