[Hashimoto toxicosis: diagnostic criteria and a 10-year follow up].
An study was carried out of the association of Basedow disease (B) and Hashimoto toxicosis (H), the response to the usual therapeutic regimens and prognostic factors for the clinical course. Seventy-one patients with the diagnosis of autoimmune hyperthyroidism were included. Sixty-one of them were prospectively followed for 8.4 +/- 2.2 years (range: 5-10 years). All patients were treated following the same criteria with antithyroid drugs and aggressive therapy (radioiodine or surgery). Two groups were differentiated: group H (62%), with titers of antimicrosomal antibodies (AMSA) > or = 1/6,400 and a positive perchlorate discharge test (PDT), and group B, with AMSA titers < 1/6,400 and negative PDT. During follow-up a three-fold number of relapses was observed in group H compared with group B, a higher frequency towards spontaneous hypothyroidism in the evolution (23% in H versus 0% in B), and higher requirements of radioiodine in H than in B. In our experience, H makes up and important percentage of autoimmune hyperthyroidism (62%) with a clinical course characterized by a higher number of relapses, higher requirements of radioiodine and a higher rate towards spontaneous hypothyroidism.
