Pituitary autoantibodies have been detected in patients with endocrine autoimmune diseases as well as in various pituitary diseases but their role in determining pituitary dysfunction is not clear. The aim of the present study was to evaluate anterior and posterior pituitary function in a group of patients with detectable pituitary autoantibodies.31 patients (29 women and 2 men) were enrolled in the study: 21 patients affected by Hashimoto’s thyroid...

Primary hyperparathyroidism (PHP) and growth hormone deficiency (GHD) are both associated with alterations of bone metabolism.GH secretion is frequently impaired in PHP patients; thus GH/IGF-I system alterations could be involved in the pathogenesis of osteoporosis.In the present study 50 post-menopausal women with PHP were evaluated by GH response to GH-releasing hormone (GHRH)+arginine (ARG) test and femoral neck bone mineral den...

Thyroid hormone resistance (THR) and pituitary TSH-secreting adenomas (TSHoma) are both characterised by increased serum free thyroid hormone levels and normal TSH concentrations. Differentiation of the two syndromes is a clinical challenge, and relies on the suppression (TRH) or lack of suppression (TSHoma) of TSH-dependent parameters and on the presence of germinal mutations in the thyroid hormone receptor beta 1 gene in patients with THR. Thyroid blood flow, evaluated using...
