Abstract
PURPOSE This review is aimed at examining whether the Homeostatic Model Assessment of Insulin Resistance (HOMA-IR) is higher in Caucasian, adult, treatment-naïve patients with acromegaly (ACRO) than in the reference population independently of diabetes presence and to evaluate the impact of treatment [surgery and somatostatin analogues (SSAs)] on its assessment. METHODS We systematically reviewed in PubMed and Web of Science from July 1985 to December 2019, registered with the code number CRD42020148737. The inclusion criteria comprised studies conducted in Caucasian adult treatment-naïve patients with active ACRO in whom HOMA-IR or basal insulin and glucose were reported. Three reviewers screened eligible publications, extracted the outcomes, and assessed the risk of biases. RESULTS Of 118 originally selected studies, 15 met the inclusion criteria. HOMA-IR was higher in ACRO than the reference population, with mean difference and (95% confidence intervals) of 2.04 (0.65-3.44), even in ACRO patients without diabetes, 1.89 (1.06-2.73). HOMA-IR significantly decreased after treatment with either surgery or SSAs - 2.53 (- 3.24- - 1.81) and - 2.30 (- 3.05- - 1.56); respectively. However, the reduction of HOMA-IR due to SSAs did not improve basal glucose. CONCLUSION HOMA-IR in treatment-naïve ACRO patients is higher than in the reference population, even in patients without diabetes. This finding, confirms that insulin resistance is an early event in ACRO. Our results also suggest that HOMA-IR is not an adequate tool for assessing insulin resistance in those patients treated with SSAs.

Abstract
BACKGROUND AND AIM Acromegaly is a rare disease with a peak of incidence in early adulthood. However, enhanced awareness of this disease, combined with wide availability of magnetic resonance imaging (MRI), has increased the diagnosis of forms with mild presentation, especially in elderly patients. Moreover, due to increased life expectancy and proactive individualized treatment, patients with early-onset acromegaly are today aging. The aim of our study was to describe our cohort of elderly patients with acromegaly. MATERIALS AND METHODS This is a cross-sectional retrospective study of 96 outpatients. Clinical, endocrine, treatment, and follow-up data were collected using the electronic database of the University Hospital of Padova, Italy. RESULTS We diagnosed acromegaly in 13 patients, aged ≥65 years, presenting with relatively small adenomas and low IGF-1 secretion. Among them, 11 patients were initially treated with medical therapy and half normalized hormonal levels after 6 months without undergoing neurosurgery (TNS). Remission was achieved after TNS in three out of four patients (primary TNS in two); ten patients presented controlled acromegaly at the last visit. Acromegaly-related comorbidities (colon polyps, thyroid cancer, adrenal incidentaloma, hypertension, and bone disease) were more prevalent in patients who had an early diagnosis (31 patients, characterized by a longer follow-up of 24 years) than in those diagnosed aged ≥65 years (5 years of follow-up). CONCLUSIONS Elderly acromegalic patients are not uncommon. Primary medical therapy is a reasonable option and is effectively used, while the rate of surgical success is not reduced. A careful cost-benefit balance is suggested. Disease-specific comorbidities are more prevalent in acromegalic patients with a longer follow-up rather than in those diagnosed aged ≥65 years.

Abstract
PURPOSE The aim of this study was to investigate the possible association of insulin-like growth factor-1 (IGF-1) with the pathogenesis of non-functioning adrenocortical adenomas (NFAs). METHODS This study included 50 female patients (mean age 54 years) with NFAs, 55 patients (mean age 48 years; 20 male, 35 female) with acromegaly and 38 female control subjects (mean age 58 years). Body mass index (BMI) and waist circumference (WC) of the subjects were recorded and blood samples for IGF-1 were taken. Insulin resistance was calculated using the homeostatic model assessment (HOMA) score. Since most of the acromegaly patients had been using medicine that could have effected insulin resistance, HOMA scores were calculated only in patients with NFAs and the controls. Computerized tomography or magnetic resonance imaging was taken of the acromegalics and controls to detect adrenal mass frequency. RESULTS The mean age was similar among the groups. As expected, the serum IGF-1 levels were significantly higher in patients with acromegaly than in patients with NFAs and the controls (p < 0.001). Although BMI, WC, and serum IGF-1 levels were significantly higher (p < 0.001) in patients with NFAs, the HOMA scores were similar between patients with NFAs and control groups. Although none of the control subjects had adrenal masses, NFAs were detected in 14 (25%) out of 55 acromegalic patients. CONCLUSIONS Higher serum IGF-1 levels in patients with NFAs compared to the control group and an increased prevalence of NFAs in acromegaly patients compared to control subjects and the general population suggest an association of IGF-1 with the etiopathogenesis of NFA.

Abstract
A 48-year-old woman diagnosed with acromegaly 21 years earlier presented at our hospital with a left adrenal tumor. Her medical history included breast cancer, thyroid cancer and an incompletely resected growth hormone (GH)-producing pituitary adenoma. Endocrinological and radiological examinations revealed subclinical adrenal Cushing's syndrome. She subsequently underwent left adrenalectomy, followed by glucocorticoid replacement therapy. Her GH and insulin-like growth factor-1 levels were insufficiently controlled, and pegvisomant was administered in addition to octreotide acetate. Following adrenalectomy, a giant hepatic hemangioma and papillary thyroid carcinoma in the residual right lobe developed, indicating the high risk of tumor development in patients with acromegaly.

Abstract
AIM Acromegaly reportedly carries an increased risk of malignant and benign thyroid tumors, with a prevalence of thyroid cancer of around 3-7%. Germline mutations in the aryl-hydrocarbon receptor (AHR) interacting protein (AIP) have been identified in familial forms of acromegaly. The molecular and endocrine relationships between follicular thyroid growth and GH-secreting pituitary adenoma have yet to be fully established. Our aim was to study the prevalence of differentiated thyroid cancer (DTC) in acromegaly, focusing on the role of genetic events responsible for the onset of thyroid cancer. METHODS Germline mutations in the AIP gene were assessed in all patients; BRAF and H-N-K RAS status was analyzed by direct sequencing in thyroid specimens, while immunohistochemistry was used to analyze the protein expression of AIP and AHR. A set of PTCs unrelated to acromegaly was also studied. RESULTS 12 DTCs (10 papillary and 2 follicular carcinomas) were identified in a cohort of 113 acromegalic patients. No differences in GH/IGF-1 levels or disease activity emerged between patients with and without DTC, but the former were older and more often female. BRAF V600E was found in 70% of the papillary thyroid cancers; there were no RAS mutations. AIP protein expression was similar in neoplastic and normal cells, while AHR protein was expressed more in PTCs carrying BRAF mutations than in normal tissue, irrespective of acromegaly status. CONCLUSIONS The prevalence of DTC in acromegaly is around 11% and endocrinologists should bear this in mind, especially when examining elderly female patients with uninodular goiter. The DTC risk does not seem to correlate with GH/IGF-1 levels, while it may be associated with BRAF mutations and AHR over-expression. Genetic or epigenetic events probably play a part in promoting thyroid carcinoma.

Abstract
OBJECTIVE The aryl hydrocarbon receptor interacting protein gene (AIP) is associated with pituitary adenoma (PA). AIP has not been sequenced in East Asian PA populations, so we performed this study in a Han Chinese cohort. DESIGN Our study included six familial PA pedigrees comprising 16 patients and 27 unaffected relatives, as well as 216 sporadic PA (SPA) patients and 100 unrelated healthy controls. METHODS AIP sequencing was carried out on genomic DNA isolated from blood samples. Multiplex ligation-dependent probe amplification and microsatellite marker analyses on DNA from the paired tumor tissues were performed for loss of heterozygosity analysis. RESULTS We identified three common and four rare single nucleotide polymorphisms (SNPs), one intron insertion, one novel synonymous variant, four novel missense variants, and a reported nonsense mutation in three familial isolated PA (FIPA) cases from the same family. Large genetic deletions were not observed in the germline but were seen in the sporadic tumor DNA from three missense variant carriers. The prevalence of AIP pathogenic variants in PA patients here was low (3.88%), but was higher in somatotropinoma patients (9.30%), especially in young adults (≤30 years) and pediatric (≥18 years) paients (17.24% and 25.00% respectively). All AIP variant patients suffered from macroadenomas. However, the AIP mutation rate in FIPA families was low in this cohort (16.67%, 1/6 families). CONCLUSION AIP gene mutation may not be frequent in FIPA or SPA from the Han Chinese population. AIP sequencing and long-term follow-up investigations should be performed for young patients with large PAs and their families with PA predisposition.

Abstract
BACKGROUND Acromegaly is well known to induce hypertrophic and hyperplastic changes in various organs and is commonly accompanied by arterial hypertension. In our study, we assess the adrenal morphology and function in a series of patients with acromegaly and possible associations with the activity of the disease and arterial hypertension. MATERIALS AND METHODS Sixty patients with acromegaly, admitted to two endocrinology departments in the time period 2005-2010, were studied prospectively. Basal IGF-1 and growth hormone levels after oral glucose tolerance test were used to assess the disease activity. All subjects underwent adrenal CT scan, basal adrenal hormonal investigation and evaluation with 24-h urinary free cortisol and cortisol levels following low-dose dexamethasone suppression test. In 33 acromegalics, the 'modified' saline infusion test (MSI), i.e. saline infusion after dexamethasone administration, was performed to identify autonomous aldosterone (ALD) secretion. RESULTS Abnormal adrenal morphology was present in 48% of our patients, and a significant association was found between the presence of arterial hypertension and adrenal morphology. Among patients with adrenal morphological changes, 55% exhibited no adrenal secretory hyperactivity, 34% autonomous cortisol, 7% ALD and 4% combined autonomous cortisol and ALD secretion, when applying recently proposed modified cut-off levels compared to widely used criteria. An increased prevalence of autonomous ALD secretion was shown among the subgroup of patients with acromegaly tested with MSI. CONCLUSIONS This study provides evidence of an increased prevalence of anatomic and functional adrenal alterations in patients with acromegaly; further studies will clarify the importance of evaluating these subjects with baseline hormonal investigation along with dynamic testing and modified cut-offs.
