| abstractText | Cold intolerance and secondary amenorrhea developed in a patient who had meningoencephalitis 4 yr prior to study. A clinical diagnosis of hypothalamic hypothyroidism was made on the basis of low serum thyroxine and triiodothyronine levels, and low plasma thyrotropin concentrations, which were responsive to thyrotropin-releasing hormone (TRH). The secretion of the remaining pituitary hormones (growth hormone, prolactin, adrenocorticotropin and gonadotropins) was intact. Not only was thyroid function normalized by oral administration of TRH, but also menses resumed after adequate replacement therapy with thyroid hormone. These results imply that hypothyroidism in this patient was due to isolated dysfunction of hypothalamic TRH release. |
