Patient description (medical language): A 51-year-old man comes to the office complaining of fatigue and some sexual problems including lack of libido. The patient doesn't smoke or use any illicit drug.  Blood pressure is 120/80 mm Hg and pulse is 70/min.  Oxygen saturation is 99% on room air.  BMI is 24 kg/m2.  Skin examination shows increased pigmentation. Genotype testing is consistent with homozygosity for the C282Y mutation. Laboratory study shows transferrin saturation of 55% and serum ferritin of 550 μg/L. He is diagnosed as a case of hemochromatosis.

Patient description (patient's own words): I am 51 years old and I just came back from the doctor's office. I'm sick and tired of being that exhausted, reaching the point where me and my lovely wife are not touching each other anymore! I'm not smoking or doing drugs! My blood pressure was 120/80 mm Hg, and pulse was 70/min and my oxygen saturation 99%. My BMI is 24. My skin also turned a bit darker lately. He tested my genes and told me that I have a mutation of the C282Y gene. I also did lab tests where my transferrin saturation was 55% and serum ferritin was 550  μg/L. The doctor diagnosed me with iron overload.

Does the patient match the trial criteria? Entailment
