A case of isolated ACTH deficiency accompanying transient primary hypothyroidism was reported along with a review of literature on isolated ACTH deficiency in Japan with special reference to its association with thyroid function. Our case, a 56-year-old woman, developed somnolence and hypoglycemia due to isolated ACTH deficiency. She also had the features of hypothyroidism, namely mounding phenomenon, muscle rigidity, increased plasma myogenic enzymes and cold intolerance. Both free T3 and free T4 were decreased, and basal as well as TRH-stimulated TSH levels were abnormally high. Plasma thyroglobulin was increased and no anti-thyroid antibodies were detected. All thyroid related physical and biochemical abnormalities disappeared after hydrocortisone replacement. A review of the literature on 103 cases disclosed that more than half the cases with isolated ACTH deficiency had a high plasma level of TSH, basal and/or TRH-induced, while the antithyroid antibodies were reported to be positive in only 13 cases. In more than 70% of such cases, the abnormality in the pituitary-thyroid axis was transient and was reversed by glucocorticoid replacement. Our case and cases in the literature indicate that the interference of thyroid hormone synthesis and/or secretion by glucocorticoid deficiency per se is the major cause of thyroid dysfunction rather than associated autoimmune thyroid disease.

A 55-year-old man who was diagnosed as having type 1 diabetes mellitus (DM) at the age of 50 years was started on insulin therapy. At 54 years old of age, he suddenly developed complex partial seizures, which frequently occurred despite intensive anti-epileptic drug therapy. Neurological examination on admission revealed hyporeflexia in bilateral upper and lower extremities without any muscle rigidity, painful spasm or cerebellar ataxia. Laboratory examination showed poor glycemic control with increased glycated hemoglobin levels. Positive anti-thyroglobulin antibodies and anti-thyroid peroxidase (TPO) antibodies and slight elevation of TSH levels are consistent with subclinical hypothyroidism due to Hashimoto's thyroiditis. A high titer of anti-glutamic acid decarboxylase (GAD) antibodies was detected in the patient's serum and cerebrospinal fluid (CSF). Electroencephalography showed temporal spikes, consistent with complex partial seizure. This is a very rare case presenting with concomitant type 1 diabetes and drug-resistant epilepsy associated with high titers of circulating and CSF anti-GAD antibodies.
