Subclinical hypothyroidism in Addison's disease.

Fourteen patients with Idiopathic Addison's disease (IAD) were studied in order to detect a possible subclinical hypothyroid state. All were clinically euthyroid with normal serum thyroxine (T4) and serum 3,5',5'-triiodothyronine (T3). Eleven had circulating thyroid microsomal antibodies in blood. The mean basal serum TSH was significantly higher than that of the control group but only three patients had values above the upper normal range. The mean value of serum T4 was decreased as compared to that of the normal persons, while serum 3,3',5'-triiodothyronine was elevated. 7.5 mU bovine thyrotrophin per kilogram body weight injected intravenously caused a rise in serum T3 not different from the response in normals. However, as well increasing serum TSH as increasing microsomal antibody titer correlated significantly to decreasing thyroidal release of T3. Our results suggest that clinically euthyroid patients suffering from IAD might have a beginning thyroidal insufficiency because of a progressive immunological damage of the thyroid.

Thyrotrophin-releasing hormone (TRH) stimulation test in manic-depressive illness.

The thyrotrophin (TSH) response to thyrotrophin-releasing hormone (TRH 200 microgram intravenously was studied in 19 patients with unipolar depression, 12 with bipolar depression, 14 with mania, and 5 with mixed manic-depressive illness. The TSH responses were decreased in all of these affective disorders compared to those found in 10 patients with reactive depression, 5 with reactive paranoid psychosis, 14 with neurotic depression, and 60 controls. The decrease of the TSH response in manics could not be accounted for by the effects of neuroleptic drugs. The TSH response in the groups with reactive depression, reactive paranoid psychosis, and neurotic depression, respectively, did not differ significantly from that found in controls. With the exception of a decrease in serum T3 level and free T3 index in the manics, no significant differences in serum T3 level or in free T3 and T4 indexes were found between the groups. Changes found in serum T4 level were due to changes in the thyroxine-binding proteins.

Coxsackie myocarditis complicating treatment of Hodgkin's lymphoma.

A fatal case of Coxsackie B4 myocarditis complicating treatment of Hodgkin's lymphoma in an adult is reported. The virus was isolated from the myocardium obtained at autopsy and light microscopy confirmed a myocarditis with involvement of the conduction system. Electron-microscopy showed dense mitochondrial inclusions. Coxsackie myocarditis rarely results in death of affected adults. It is postulated in this case that the treatment of the Hodgkin's lymphoma resulted in B lymphocyte depletion, allowing a more virulent infection to occur with resultant fatal myocarditis.
