Background Studies comparing primary medical treatment of acromegaly with surgery are often non-randomized, and not stratified by illness severity. We prospectively compared primary medical therapy with pituitary surgery in patients with acromegaly. All patients had macroadenomas, at least one random human growth hormone (GH) level ≥12.5 ng/mL, elevated IGF-I levels and failure to suppress GH to <1 ng/mL...
Acromegaly is associated with an enhanced mortality, with cardiovascular and respiratory complications representing not only the most frequent comorbidities but also two of the main causes of deaths, whereas a minor role is played by metabolic complications, and particularly diabetes mellitus. The most prevalent cardiovascular complications of acromegaly include a cardiomyopathy, characterized by cardiac...
Context The somatostatin analogues octreotide LAR and lanreotide Autogel have been evaluated for the treatment of acromegaly in numerous clinical trials, with considerable heterogeneity in reported biochemical response rates. This review examines and attempts to account for these differences in response rates reported in the literature. Evidence acquisition PubMed was searched for English-language...
Introduction In nearly all cases, acromegaly is caused by excess GH from a pituitary adenoma, resulting in elevated circulating levels of GH and, subsequently, IGF-1. Treatment goals are to eliminate morbidity and restore the increased mortality to normal rates. Therapeutic strategies aim to minimize tumor mass and normalize GH and IGF-1 levels. Somatostatin analogues are the medical treatment of...
Purpose In a 10-week proof-of-concept study (LINC 1), the potent oral 11β-hydroxylase inhibitor osilodrostat (LCI699) normalized urinary free cortisol (UFC) in 11/12 patients with Cushing’s disease. The current 22-week study (LINC 2; NCT01331239) further evaluated osilodrostat in patients with Cushing’s disease. Methods Phase II, open-label, prospective study of two patient cohorts. Follow-up cohort:...
Purpose Report the efficacy and safety of pasireotide sc in patients with Cushing’s disease during an open-ended, open-label extension to a randomized, double-blind, 12-month, Phase III study. Methods 162 patients entered the core study. 58 patients who had mean UFC ≤ ULN at month 12 or were benefiting clinically from pasireotide entered the extension. Patients received the same dose of pasireotide...
Purpose Thyrotropin-secreting pituitary adenomas (TSHomas) represent a rare subtype of pituitary tumors. Neurosurgery (NCH) is still considered the first-line therapy. In this study we aimed to investigate the outcome of different treatment modalities, including first line somatostatin analogs (SSA) treatment, with a specific focus on neurosurgery-related complications. Methods We retrospectively...
To evaluate the metabolic effects of first-line somatostatin analogues or surgery in acromegaly. Retrospective, comparative, 12-month follow-up. Two hundred and thirty one patients (123 men, age 47.32 ± 14.63 years) with active acromegaly, first line treatments were somatostatin analogues in 151 (65.4%) and surgery in 80 (34.6%). Metabolic syndrome (MS) parameters, glucose, insulin and GH during oral...
The interrelationship between prolactin (PRL) and the immune system have been elucitaded in the last decade, opening new important horizons in the field of the immunoendocrinology. PRL is secreted not only by anterior pituitary gland but also by many extrapituitary sites including the immune cells. The endocrine/paracrine PRL has been shown to stimulate the immune cells by binding to PRL receptors...
Cushing's disease (CD), the chronic endogenous hypercortisolism derived from an ACTH-secreting pituitary adenoma, and multiple osteochondromatosis (MO), a congenital mesoderm dyschondroplasia, represent two distinct rare neoplastic diseases. Clinical appearance of MO usually occurs during the first-second decade of life. In fact, the growth of osteochondromas parallels the patient's growth, then becoming...
The skeletal system is a common target of glucocorticoids. Structural and functional impairment of skeletal system is a relevant cause of morbidity and disability in patients with Cushing's syndrome. Thirty-six patients long-term (3.9 ± 0.5 yrs) cured from Cushing's disease (CD), 26 with adulthood-onset CD (AOCD) and 10 with childhood-onset CD (COCD) and 2 groups of controls, 24 age- and sex-matched...
Cardiac involvement is common in acromegaly. Evidence for cardiac hypertrophy, dilation and diastolic filling abnormalities has been widely reported in literature. Generally, ventricular hypertrophy is revealed by echocardiography but early data referred increased cardiac size by standard X-ray. Besides, echocardiography investigates cardiac function and value disease. There are new technologic advances...
The aim of this study was to evaluate the efficacy of a 6-month treatment with lanreotide (LAN) (60–90 mg/month) alone and combined with cabergoline (CAB) (1.5-3 mg/week) in 10 acromegalic patients previously demonstrated to be poor responders to octreotide (OCT) (0.6 mg/day) alone and combined with quinagolide (CV) (0.6 mg/day). All patients had previously undergone unsuccessful surgery and none...
In 18 patients with hypothalamo-pituitary diseases aged over 60 years and in 18 sex, age- and BMI-matched healthy subjects, the results of plasma IGF-I and IGF-BP3 levels and the GH response to GHRH+arginine test (GHRH+ATT) were correlated to the results of body composition, serum osteocalcin (OC) and urinary cross-linked N-telopeptides of type I collagen (Ntx) and the bone mineral density (BMD)....
