BACKGROUND: Factors associated with initial and delayed remission after growth hormone (GH)-secreting pituitary adenoma excision have not been completely elucidated. METHODS: We recruited 185 consecutive patients treated for GH-secreting pituitary adenomas between January 2013 and December 2014 and assessed their tumor characteristics and surgical outcomes. The criteria for initial or delayed remission (based on the 2010 consensus criteria) were normalized insulin-like growth factor 1 (IGF-1) levels, GH levels below 0...

CONTEXT: The oral glucose tolerance test (OGTT) is considered the most useful method for diagnosing active acromegaly and for patient follow-up after neurosurgery. Despite its widespread use, only a few small studies have so far focused on patients' clinical features associated with different GH responsiveness to OGTT. OBJECTIVE: We aimed to investigate the association between glucose-induced GH response and endocrine profiles, clinical manifestations, and response to therapy in a large cohort of patients with acromegaly...

OBJECTIVE Acromegaly results in disfiguring growth and numerous medical complications. This disease is typically caused by growth hormone (GH)-secreting pituitary adenomas, which are treated first by resection, followed by radiation and/or medical therapy if needed. A subset of acromegalics have dual-staining pituitary adenomas (DSPAs), which stain for GH and prolactin. Presentations and treatment outcomes for acromegalics with DSPAs are not well understood. METHODS The authors retrospectively reviewed the records of more than 5 years of pituitary adenomas resected at their institution...

OBJECTIVE: Uncontrolled acromegaly is associated with increased morbidity and mortality. Despite multimodal therapeutic options, adequate control can be challenging and lead to prolonged exposure to growth hormone excess. The aim of this study was to assess treatment patterns and outcomes in patients with acromegaly following surgery at a single institution. METHODS: A retrospective analysis of response to treatment modalities for patients with a new diagnosis of acromegaly at the Mayo Clinic in Rochester, Minnesota, from 1995-2015...

BACKGROUND: Cavernous sinus (CS) invasion is an unfavorable factor hindering the remission of growth hormone (GH)-secreting pituitary adenomas. Little data exist on aggressive surgical resection, however. We investigated the role of CS exploration for GH-secreting pituitary adenomas with CS invasion. METHODS: We classified 132 patients with GH-secreting pituitary adenomas invading CS into 4 groups. The patients underwent surgery using a microsurgical transsphenoidal approach (TSA) with endoscopic assistance...

BACKGROUND: Transsphenoidal surgery (TSS) is the cornerstone of acromegaly treatment, however there are no robust predictors of surgical outcome and remission can only be defined three months after surgery. PURPOSE: To analyze if biochemical, demographical, radiological, and immunohistochemical characteristics are predictors of surgical remission and investigate if immediate postoperative GH and IGF-I levels can help defining remission earlier. METHODS: Consecutive acromegaly patients submitted to TSS between 2013-2016 were evaluated...

BACKGROUND: Plurihormonal adenomas (PHAs) represent 10%-15% of all functioning pituitary adenomas. The most frequent hormonal associations are with prolactin and growth hormone (GH). Here we describe a rare case of functional adrenocorticotropic hormone (ACTH) and GH microadenoma and report our findings from a systematic literature review of PHA. METHODS: We searched PubMed using the terms "plurihormonal pituitary adenoma," "ACTH GH pituitary adenoma," and "acromegaly AND Cushing's disease"...

CONTEXT: Chronic excess of growth hormone (GH) often leads to systemic complications. The reversibility of these complications after GH resolution is not fully understood. OBJECTIVE: To investigate when and to what extent will the comorbidities be ameliorated. DESIGN: We conducted a prospective study comprising 24 patients with acromegaly, who achieved remission after transsphenoidal surgery. The dynamic changes of endocrine, cardiovascular, respiratory, sleep, bone and morphology parameters were evaluated at enrollment and 1 week, 1 month, 3 months, 6 months and 12 months after surgery...

PURPOSE: High GH and IGF I levels increase tubular phosphate reabsorption in patients with acromegaly. We aimed to investigate the utility of serum phosphorus levels as an indicator for predicting chance of remission in acromegaly patients. DESIGN: Fifty-one patients (n: 51; F: 24, M: 27) with diagnosis of acromegaly were included in the study. Plasma IGF-1, Phosphorus (P) and nadir GH levels on oral glucose tolerance test (OGTT) at the time of diagnosis were analysed retrospectively...

Acromegaly is a severe disease associated with chronic overproduction of the growth hormone (GH) and insulin-like growth factor-1 (IGF-1), which is caused in most cases by pituitary adenoma. The main causes of mortality in acromegaly are cardiovascular diseases, respiratory diseases, and cancers. At present, the most effective treatment for acromegaly is surgical pituitary adenomectomy. Complete resection of pituitary tumors leads to the normalization of GH and IGF-1 levels, regression of symptoms, and a reduction in the risk of death...

BACKGROUND: In the immediate postoperative period following resection of growth hormone (GH)-secreting pituitary tumors, serum concentrations of GH have limited ability to predict remission of acromegaly. Since many actions of GH actions are mediated by insulin-like growth factor-1 (IGF-I), we aimed to determine the rates of fall of IGF-I during 72 h after surgical resection of pituitary tumors. METHODS: We studied patients who were undergoing pituitary surgery for acromegaly...
