Goitre in 1835. The German Karl Adolph von Basedow also independently reported the same constellation of symptoms in 1840, while earlier reports of the disease were also published by the Italians Giuseppe Flajani and Antonio Giuseppe Testa, in 1802 and 1810 respectively, and by the English physician Caleb Hillier Parry (a friend of Edward Jenner) in the late 18th century. Paracelsus (1493–1541) was the first person to propose a relationship between goitre and minerals (particularly lead) in drinking water. Iodine was later discovered by Bernard Courtois in 1811 from seaweed ash. Goitre was previously common in many areas that were deficient
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
