Efficacy of Rapid Escalation of Cabergoline in Comparison to Conventional Dosing in Prolactin Secreting...
MacroprolactinomaTo study the effects of rapid escalation of Cabergoline in comparison to conventional dosing in macroprolactinomas. Rapid escalation of cabergoline may help in earlier normalization of prolactin and shrinkage of tumor mass, and thus decrease the cumulative dose of cabergoline altogether.
Cabergoline Combined Hydroxychloroquine/Chloroquine to Treat Resistant Prolactinomas
ResistanceDisease1 moreThe purpose of this study is to preliminarily evaluate the safety and efficacy of cabergoline combined hydroxychloroquine/chloroquine(HCQ/CQ) therapy for cabergoline-Resistant Prolactinomas
Dopamine D2 Receptors(D2R) Imaging in Prolactinomas
ProlactinomaTo study the in vivo expression of dopamine D2 receptors in prolactinoma and the predictive role of dopamine D2 receptors PET-MR imaging in the therapeutic effect of dopamine agonists.
Exercise Capacity and Physical Activity Level in Prolactinoma Patients
ProlactinomaProlactinoma, one of the most common pituitary adenomas, is an adenoma that causes excessive prolactin (PRL) secretion. An increase in prolactin level can cause weakness, decrease in muscle mass and fatigue. It is not known in detail to what extent it affects quality of life, functional exercise capacity, cardiovascular disease risk factors, physical activity level, fatigue and sleep quality in prolactinoma patients. It is aimed to compare how much exercise capacity, physical activity level, sleep quality, perception of fatigue and quality of life of prolactinoma patients are affected compared to healthy individuals and to examine the factors associated with exercise capacity in prolactinoma patients.
Validation of a Quality of Life Metric "Prolac-10"
ProlactinomaProlactin-Producing Pituitary Tumor3 moreThis is a short-term validation study of a quality of life metric "Prolac-10" for patients diagnosed with a prolactinoma, undergoing new medical therapy.
Interdisciplinary Pituitary Disorders Centre of Excellence: Assessment of Patient Education Tools...
Pituitary NeoplasmsProlactinoma3 moreThe purpose of this research study is to determine the utility of educational materials designed to inform patients of their pituitary condition, in an effort to assist the patients, families, and staff deal with pituitary tumours and related conditions in the best way possible. We have developed a website, informational videos, and a brochure for pituitary tumour patients and their families. The primary outcome measures will be 1) the level of knowledge that patients have of their condition before and after reviewing the materials provided; and 2) ease of use and user satisfaction of the materials. We hypothesize that our informative multimedia educational package will not only improve the health literacy and self-efficacy of patients and their families, but will also improve quality of care.
Rhinological Outcomes in Endonasal Pituitary Surgery
Pituitary NeoplasmPituitary Adenoma3 moreThis is a prospective, multi-center observational study designed to address patient-reported nasal outcomes in adults undergoing endoscopic and microscopic surgical removal of pituitary tumors. The primary objective of this study is to determine the difference in nasal outcomes by using the Anterior Skull Base (ASK) Nasal survey between patients treated with endoscopic surgical technique and those treated with microscopic surgical technique. Patients will be given the ASK Nasal survey to assess their nasal functioning and overall health before their surgery, and at post-operative visits 1-2 weeks, 3 months, and 6 months.
Insulin Resistance in Women With Prolactinoma
ProlactinomaInsulin Resistance1 moreProlactin is suggested to influence insulin resistance, but scarce data is available on the metabolic profile of patients with prolactinoma. The purpose of the protocol was to evaluate cardiovascular disease risk factors in women with prolactinoma treated with dopamine agonists and to study the influence of disease control and anthropometry on their metabolic profile.
Cardiac Valve Complications in Prolactinomas Treated With Cabergoline
ProlactinomasDopamine agonists are first-line agents for the treatment of prolactinomas (1) and Parkinson's disease (2). There is evidence supporting a causal relationship between the occurrence of drug-induced "restrictive" valvular heart disease and treatment with pergolide (3): in several cases, the valvulopathy improved when pergolide was discontinued (4). Valvular heart damage has also been reported with the ergot-derived dopamine agonists bromocriptine and cabergoline (5,6). Two recent studies (7,8) have further demonstrated that both pergolide and cabergoline are associated with an increased risk of new cardiac valve regurgitation in patients treated for Parkinson's disease. The valvular abnormalities seen with ergot-derived dopamine agonists are similar to those observed in patients receiving ergot alkaloid agents (such as ergotamine and methysergide) in the treatment of migraine, or fenfluramine and dexfenfluramine in the treatment of obesity. These abnormalities also closely resemble carcinoid-related valvulopathies (9). Cardiac valve disease has never been reported in patients with prolactinomas who require treatment with dopamine-agonists even life-long (1). At variance with patients with Parkinson's disease, patients with prolactinomas are younger and are treated with an average dose of dopamine-agonists that is significantly lower (median bromocriptine dose 5 mg/day and median cabergoline dose 1 mg/week). Because of the young age of treatment beginning (most patients with microprolactinomas start dopamine-agonist treatment in early adulthood), treatment might be continued for over 3 decades: the cumulative risk of low doses of dopamine agonists for such a long period of treatment is currently unknown. To assess the prevalence of cardiac valve disease in patients treated with cabergoline, we wish to perform an echocardiography screening in a large representative sample of patients with prolactinoma who were treated with cabergoline for at least 12 months and in a group of control subjects recruited prospectively. We wish to evaluate the severity of regurgitation for the mitral, aortic, and tricuspid valves. Changes in cardiac valve apparatus was compared with treatment duration and cumulative cabergoline dose.
Dopamine Agonists Withdrawal Study of Invasive Prolactinomas Involving the Cavernous Sinus
Invasive Prolactinomas Involving the Cavernous SinusThe purpose of this study is to observe whether dopamine agonists can be safely withdrawn after the tumor volume and prolactin level of invasive prolactinomas involving the cavernous sinus have been effectively controlled through pharmacological treatment.
