In patients with primary hypothyroidism (PH), L-T4 replacement therapy can safely be adjusted to the individual needs by testing serum thyrotropin (TSH) concentration exclusively. Central hypothyrodism (CeH) is a particular hypothyroid condition due to an insufficient stimulation by TSH of an otherwise normal thyroid gland. CeH is about 1000-fold rarer than PH and raises several challenges for clinicians, mainly because they cannot rely on the systematic use of the reflex TSH strategy for diagnosis or therapy monitoring. Therefore, L-T4 replacement in CeH should rely on the combined evaluation of several biochemical and clinical parameters in order to overcome the lack of accuracy of the single index. The management of CeH replacement is further complicated by the frequent combination with other pituitary deficiencies and their treatment.

Abstract
In patients with primary hypothyroidism (PH), L-T4 replacement therapy can safely be adjusted to the individual needs by testing serum thyrotropin (TSH) concentration exclusively. Central hypothyrodism (CeH) is a particular hypothyroid condition due to an insufficient stimulation by TSH of an otherwise normal thyroid gland. CeH is about 1000-fold rarer than PH and raises several challenges for clinicians, mainly because they cannot rely on the systematic use of the reflex TSH strategy for diagnosis or therapy monitoring. Therefore, L-T4 replacement in CeH should rely on the combined evaluation of several biochemical and clinical parameters in order to overcome the lack of accuracy of the single index. The management of CeH replacement is further complicated by the frequent combination with other pituitary deficiencies and their treatment.Pubblicazioni consigliate
