Abstract
The Schmidt Syndrome (Type II Autoimmune-Syndrome) is characterised by an autoimmune adrenalitis in combination with a chronic lymphocellular thyreoiditis resulting in insufficiency of these organs in adulthood. Combination with diabetes is possible. The diagnosis is usually established by clinical examination and analysis of serum hormone levels (adrenocorticotropin hormone [ACTH], cortisol, thyroid stimulating hormone [TSH], triiodothyronine [fT3], thyroxine [fT4]).
In the present case, initial diagnosis was rapid progressive liver failure of unknown origin with consecutive multiple organ dysfunction syndrome including dysfunction of heart, lungs, and kidneys. Frequent and less frequent causes of liver failure were ruled out, e.g. viral or autoimmune hepatitis, Budd-Chiari-syndrome, toxic, or drug induced liver failure. In retrospect, the multiple organ dysfunction syndrome was caused by hypoperfusion due to severe hypovolemia and hypoperfusion was induced by adrenocortical insufficiency proven by endocrinological testing. The clinical course of this case stresses the importance of the hormone balance in the critical ill patient. The guideline for treatment of patients with assumed hormonal dysregulation should include a full hormone status prior to substitution. The present case report also illustrates the importance of clinical signs and careful consideration of the medical history in detecting an autoimmune endocrine disease.
