Multicenter Evaluation of the Effect of Upfront Radiosurgery on Residual Growth Hormone-secreting...
Acromegaly Due to Pituitary AdenomaIn this study, the investigators hypothesize that upfront gamma knife radiosurgery with drug therapy is superior in the treatment of growth hormone-secreting pituitary tumors after primary surgical treatment compared with the drug therapy alone. This study can provide useful clinical information in the treatment of patients with acromegaly.
Pasireotide LAR and Pegvisomant Study in Acromegaly
AcromegalyThe objective of this study is to assess the efficacy of Pasireotide Long Acting Release (LAR) alone and in combination with weekly Pegvisomant (PEGV) in acromegaIy patients previously controlled with combination treatment of long-acting Somatostatin analogs (LA-SSAs) and PEGV.

AcromegalyHeart Failure2 moreThe purpose of this study is to evaluate changes in left ventricular mass and cardiac function in patients with active acromegaly before and after treatment with the growth hormone receptor antagonist pegvisomant for one year.
A Pilot Study of Empagliflozin in the Treatment of Acromegalic Cardiomyopathy
AcromegalyCardiomyopathiesAcromegaly is a disease characterized by excess growth hormone(GH) and insulin like growth factor(IGF)-1. Pituitary GH secreting adenoma is the major cause of acromegaly. Acromegalic cardiomyopathy is one of the leading causes of death in acromegalic patients. No efficient medicine is available for acromegalic cardiomyopathy until now and there were limited studies. Empagliflozin is proved to decrease the risk of heart failure in diabetic patients and independent of blood glucose control. We planed to evaluate the structure of heart by MRI before and after 6 months treatment with empagliflozin in acromegalic patients to investigate the effect of empagliflozin on acromegalic cardiomyopathy.
Prevalence of Acromegaly in a Diagnostic Consultation for Sleep Apnea Syndrome
Sleep Apnea SyndromePrevalence of sleep apnea syndrome in patients with acromegaly is about 70%. It seems that comorbidities of arterial hypertension or type 2 diabetes are more severe in patients with acromegaly and sleep apnea syndrome. Besides sleep apnea syndrome associated to acromegaly gives rise to few symptoms, that explains it is under diagnosed. The mechanisms of the association are based on maxillofacial modifications linked to acromegaly, a thickening of soft tissues with deposits of glyco-aminoglycanes but probably also because of the associated obesity, of the potential existence of a goiter and a muscular dystrophy of the dilatative muscles of the pharynx. At present, no study clearly documented prevalence of acromegaly in a diagnostic consultation for sleep apnea syndrome.
Hormonal Outcomes in Acromegalic Patients With Treated Surgery With or Without Long Acting Somatostatin...
AcromegalyLong-term (up to 3 years) clinical and hormonal outcomes in acromegalic patients with treated surgery with or without long acting somatostatin analogues.
Acromegaly & Sleep Apnoea
AcromegalyEstimates of the prevalence of acromegaly, a condition resulting from excess growth hormone secretion, are as high as 1:1000. If detected late acromegaly increases the risk of joint destruction, heart disease, sleep apnoea, high blood pressure, diabetes, and polyps in the colon. To have a greater effect on long-term outcomes this disease needs to be detected early. By screening a 'high risk' population (sleep apnoea clinic) the investigators may be able to detect these patients earlier and prevent late complications of the disease. At LTHT the referral pathway for new referrals to the sleep apnoea clinic involves initial attendance to pick up a pulse oximeter to wear overnight to measure oxygen levels. These readings show approximately 1:4 patients displays evidence of significant obstructive sleep apnoea to warrant referral to the treatment group for continuous positive airway pressure (CPAP), weight management, and occasionally mandibular adjustment. Patients attending the sleep apnoea clinic either as new referral or for review will be asked to participate in the proposed study. The study is cross-sectional in design incorporating two sub-populations within the sleep apnoea clinic. The first cohort comprises patients under follow-up known to have sleep apnoea, and the second cohort those patients prospectively attending the sleep apnoea clinic for assessment. If after an explanation of the study they agree to participate blood will be taken for assessment of IGF-I and they will be asked to complete a simple questionnaire. The aim will to be to screen 1000 consecutive patients. The questionnaire will incorporate five simple questions to be completed with a 'yes' or 'no' answer. Where IGF-I levels are elevated patients will be investigated further for the possibility of acromegaly. The presence of biochemically proven acromegaly will be used to determine if the simple question has sufficient sensitivity to use as a screening tool.
Non Interventional Post Marketing Programme in Acromegaly
AcromegalyThe purpose of this study, is to assess the safety and local tolerability of the long-term use of Somatuline Autogel when administered by patients or their partners ("Home Injection Group") and the safety and local tolerability in patients receiving their injection from a healthcare professional (HCP) ("Reference Group").
Vitamin D Metabolism in Patients With Endocrine Disorders
Pituitary ACTH HypersecretionAcromegaly3 moreThis prospective controlled interventional study aims to reveal the diversity of vitamin D metabolism in patients with certain endocrine disorders (Cushing's disease, acromegaly, primary hyperparathyroidism, diabetes mellitus type 1) compared to healthy adults. All patients will receive a single dose (150,000 IU) of cholecalciferol aqueous solution orally. Laboratory assessments including serum vitamin D metabolites (25(OH)D3, 25(OH)D2, 1,25(OH)2D3, 3-epi-25(OH)D3, 24,25(OH)2D3 and D3), free 25(OH)D, vitamin D-binding protein (DBP) and parathyroid hormone (PTH) as well as serum and urine biochemical parameters will be performed before the intake and on Days 1, 3 and 7 after the administration.
Study in Polish Acromegalic Patients Treated With Somatuline Autogel
AcromegalyThe purpose of this study is to evaluate over the 24 month prospective follow up - in everyday clinical practice - resource utilization and effectiveness of the treatment of acromegalic patients in Poland with Somatuline Autogel 120 mg including extended injection intervals.
