Patient description (medical language): A 33-year-old woman comes to clinic complaining of progressive fatigue, decreased appetite, and 11-lb weight loss in the past 2 months.  She uses levothyroxine because of the previously diagnosed Hashimoto disease. She has no other medical conditions and does not use tobacco, alcohol, or illicit drugs.  Physical examination shows a generalized increase in pigmentation of the skin.  Measurement of serum cortisol before and after administration of exogenous adrenocorticotropic hormone (ACTH) shows no difference in the levels. Stable glucocorticoid replacement therapy starts for her with the diagnosis for primary adrenal insufficiency (Addison disease)

Patient description (patient's own words): I went to the clinic because I was really suffering from fatigue and decreased appetite and I also lost 11 pounds over the past two months. I'm just 33 years old so that's not normal, especially for a woman. I take levothyroxine because I have been diagnosed with Hashimoto disease. I don't have any other medical condition, and I don't smoke I don't drink, and I don't do drugs. They also did my physical examination and they saw that I had an increase in pigmentation of my skin. They measured my cortisol level before and after giving me some ACTH hormone, and the results came back with no difference whatsoever. The doctor told me I have Addison disease and put me under glucocorticoid therapy.

Does the patient match the trial criteria? Entailment
