title: Silent thyroiditis, isolated corticotropin deficiency, and alopecia universalis in a patient with ulcerative colitis and elevated levels of plasma factor VIII: an unusual case of autoimmune polyglandular syndrome type 3.
abstract: OBJECTIVE
  To describe an unusual case of autoimmune polyglandular syndrome (APS) type 3 and provide a brief review of the literature.
  
  
  METHODS
  We present the clinical course and laboratory data of a patient with silent thyroiditis, isolated corticotropin (adrenocorticotropic hormone or ACTH) deficiency, alopecia universalis, and ulcerative colitis with an associated hypercoagulable state. The related literature is also reviewed briefly.
  
  
  RESULTS
  A 43-year-old man who had a history of ulcerative colitis with an associated hypercoagulable state and alopecia universalis was referred to the endocrinology department for evaluation of fatigue and a mildly elevated level of thyrotropin (thyroid-stimulating hormone or TSH). He previously had mildly increased TSH levels, for which low-dose levothyroxine therapy had been prescribed. During use of this therapy, a suppressed TSH level developed, necessitating discontinuation of thyroid hormone therapy; a subsequent increase in TSH value was followed by a spontaneous return to euthyroidism. An ACTH stimulation test revealed adrenal insufficiency. His ACTH level was low, 21-hydroxylase antibodies were not present, and further testing demonstrated otherwise intact pituitary function. Magnetic resonance imaging of his pituitary gland showed normal findings. Treatment with hydrocortisone promptly decreased his fatigue. He was found to have an elevated factor VIII level as the cause of his hypercoagulable state. The patient continues to feel well with use of hydrocortisone therapy and has normal thyroid function.
  
  
  CONCLUSIONS
  This patient's components of APS type 3 have not been previously reported; thus, the complex nature of the APS variants is supported.
