Toxic multinodular goitre Toxic multinodular goitre Toxic multinodular goiter (also known as toxic nodular goiter, or Plummer's disease) is an active multinodular goiter associated with hyperthyroidism. It is a common cause of hyperthyroidism in which there is excess production of thyroid hormones from functionally autonomous thyroid nodules, which do not require stimulation from thyroid stimulating hormone (TSH). Toxic multinodular goiter is the second most common cause of hyperthyroidism (after Graves' disease) in the developed world, whereas iodine deficiency is the most common cause of hypothyroidism in developing-world countries where the population is iodine-deficient. (Decreased iodine leads to decreased thyroid hormone.) However, iodine deficiency
Selective immunoglobulin A deficiency IVIG, then a physician may treat the other condition with IVIG. The use of IVIG to treat SIGAD without first demonstrating an impairment of specific antibody formation is extremely controversial. Prognosis is excellent, although there is an association with autoimmune disease. Of note, selective IgA deficiency can complicate the diagnosis of one such condition, celiac disease, as the deficiency masks the high levels of certain IgA antibodies usually seen in celiac disease. As opposed to the related condition CVID, selective IgA deficiency is not associated with an increased risk of cancer. Patients with Selective IgA deficiency are at risk of
