IntroductionPrimary autoimmune hypophysitis (PAHs) is a rare inflammatory disease of the pituitary gland. Although largely investigated, the pathogenesis of PAH is not completely clarified. We aimed to investigate the immune response in PAHs.Material and methodsSerum anti-pituitary and anti-hypothalamus antibodies (respectively APAs and AHAs) were investigated though an indirect immunofluorescence on monkey h...

Introduction: Somatotropinomas are benign pituitary tumors with heterogeneous biological and clinical behavior. The tumor microenvironment (TME) is an environment generated by the interaction between tumor cells and the host immune system. It affects both the behavior of the tumor and the outcome of the therapy. The GNAS gene encodes the alpha subunit of G proteins associated with hormone receptors such as TSH, PTH, GHRH, FSH/lH, ACTH. Mutation of this gene has been associated...

Introduction: Skeletal fragility is a relevant and not-reversible complication of acromegaly, involving around 30-40% of patients since the disease diagnosis. Few studies have investigated the effects on skeletal health of medical therapies for acromegaly. We aim to investigate the frequency of incident vertebral fractures (i-VFs) in patients treated with Pasireotide Lar + Pegvisomant (study group), after at least 24 consecutive treatment months and to compare the i-VFs freque...

Background: Pituitary metastases are rare findings and account for 1% of surgically treated pituitary lesions. Despite the low incidence, given the frequent compression exerted on surrounding structures, pituitary metastases can present with major symptoms such as headache, visual disturbances and visual field. Ultimately, damage to the pituitary gland may be associated with electrolyte disturbances.Clinical case: A 57-year-old male patient was admitted ...
