The arteriovenous difference in plasma adrenaline was similar during hypothyroidism compared to euthyroidism, indicating similar peripheral extraction rate of catecholamines during hypothyroidism as compared to euthyroidism.

One study examined peripheral 5-HT concentrations and the activity of the metabolizing enzyme monoamine oxidase MAO before and after treatment in 45 hyperthyroid patients and compared the activity to that present in healthy, euthyroid controls. After 3 months of treatment with carbimazole and the associated decline of plasma T 3 and T 4 concentrations towards normal levels, MAO activity increased and plasma serotonin concentrations decreased, however, not to within the range of the normal control subjects.
