The geographical distribution of thyrotoxicosis in England according to the presence or absence of TSH-receptor antibodies.
In a prospective study of the incidence of thyrotoxicosis sera from 216 thyrotoxic patients in seven English towns were assayed for TSH-receptor antibodies. The incidence of antibody negative thyrotoxicosis correlated closely with the previous prevalence of endemic goitre in the towns (r = 0.9) indicating a high current incidence of toxic nodular goitre in previously goitrous towns. Antibody positive thyrotoxicosis, an indicator of Graves' disease, showed no correlation with goitre although there was statistically significant geographical variation in incidence. The percentage of all thyrotoxic patients who were antibody positive varied between towns, from 35% to 92%.
