methimazole and Addison-Disease

To present a case of primary male infertility with severe oligospermia and hyperpigmented skin as the main presenting clinical signs.. Case report.. University-affiliated teaching hospital.. A 32-year-old male with severe oligospermia and his 31-year-old female partner with normal cycles.. Hydrocortisone, fludrocortisone, methimazole, and eventual IVF.. Improved semen analysis, correction of Addison's disease, correction of hyperthyroidism, and ART pregnancy.. Severe oligospermia of 5 million per milliliter with 15% motility and ACTH level of 2,800 pg/mL on presentation. Endocrinology evaluation revealed cortisol of <0.1 microg/dL, and Cortrosyn test showed no response (Addison's disease). The patient was incidentally found to have a thyroid stimulating hormone level of <0.1 microIU/mL, T4 of 9.5 microg/dL, Free T4 Index calculation of 11.6 microg/dL, and quantitative triiodothyronine of 273 ng/dL on presentation. His Addison's disease was managed with hydrocortisone and fludrocortisone, and his hyperthyroidism, with methimazole. Semen parameters increased to 34 million per milliliter with 45% motility and 5% Kruger morphology 1 year after initial presentation. Hormone parameters normalized. Rather than allowing for more time for natural conception or IUI, the couple decided to proceed with IVF because of insurance coverage before semen parameters normalized.. This is the first reported case of Addison's disease presenting as male infertility with hyperpigmentation of the skin being the only other presenting sign. The underlying etiology of the Addison's in this case remains uncertain, but it is presumed because of autoimmunity. Addison's disease may be associated with hyperthyroidism, and hyperthyroidism may have contributed to the oligospermia. This case highlights why men with abnormal semen parameters should be thoroughly evaluated before proceeding with assisted reproduction.

Two cases of hyperthyroidism with hyperpigmentation are presented. In both cases, hyperpigmentation was seen on the lower extremities, most strikingly on the shins, backs of the feet and the nail bed. Histology of the pigmented skin showed basal melanosis and heavy deposition of haemosiderin around dermal capillaries and sweat glands. Treatment with mercazol in both cases resulted in no significant waning of pigmentation. Distribution of hyperpigmentation, haemosiderin deposition and poor response to the treatment may be characteristic features of the pigmentation caused by hyperthyroidism, and may represent differences from the pigmentation seen in Addison's disease.

Each of the endocrine emergencies discussed here--adrenal crisis, myxedema coma, and thyroid storm--represents decompensation of a long-standing endocrine disorder and is precipitated in most cases by some stressful event. Each necessitates immediate, aggressive therapy. Even with such therapy, the mortality rate remains 30% to 50% for myxedema coma and 30% to 40% for thyroid storm. Therapy must be instituted on the basis of strong clinical suspicion, without delay for results of specific hormone assays to confirm the diagnosis. Although some risks may be inherent in this approach, they are minimal compared with the risks of delaying therapy until laboratory confirmation can be obtained. Immediate therapy consists of specific measures to correct the hormone deficit or excess; the precipitating cause should then be sought and treated.
