OBJECTIVE Reduction of plasma free fatty acids leads to enhanced GH response after stimulation by GH-releasing hormone (GHRH). We studied the clinical usefulness of combined administration of acipimox and GHRH for the diagnosis of GH deficiency. DESIGN We evaluated 35 patients [mean age 53.0 years; mean body mass index (BMI) 26.7 kg/m(2) ] after pituitary surgery. We compared GH responses after acipimox and GHRH with the GH response during an insulin tolerance test (ITT) and, in a subgroup of 12 patients, with the GHRH/arginine test. The acipimox/GHRH test was additionally performed in 21 control subjects (mean age 53.8 years; mean BMI 24.7 kg/m(2) ). RESULTS In the patients, the mean (+/- SEM) peak GH was almost four-fold higher after acipimox/GHRH (6.94 +/- 1.07 mug/l, range 0.46-23.1; P

TYPE 1 diabetes ,METABOLIC regulation ,GLYCOSYLATED hemoglobin ,C-peptide ,CYTOKINES ,T cells - Abstract
The onset of type 1 diabetes coincides with the final phase of β-cell destruction. In some cases, this period is characterized by the presence of a functional reserve of β-cells, favouring an adequate metabolic control (honeymoon phase). Therefore, the extension of this situation could have evident benefits in subsequent diabetes management. We aimed to study the influence of regular physical activity before and after the onset of the disease. We did an observational study of 2 groups of type 1 diabetic patients from onset to a 2-year period. One group (n = 8) exercised regularly (5 or more hours/week) before onset and continued doing so with the same regularity. The second group (n = 11) either did not perform physical activity or did so sporadically. Circulating glycated haemoglobin (HbA 1c ), C-peptide, protein carbonyls and basal cytokine levels were determined at the beginning and at the end of the 1
st and 2nd year. The more active group debuted with and maintained significantly lower HbA 1c levels and insulin requirements compared to the more sedentary group. C-peptide levels were only signifi cantly higher in the active group at the moment of onset compared to the sedentary group. In addition, determination of basal circulating cytokines revealed a large variability between individuals but no significant differences when comparing the groups. Altogether, the obtained results seem to indicate that physical activity allows a better control at the moment of onset regarding glycaemic control, residual endocrine pancreatic mass and subsequent insulin requirements.

Sexual dimorphism of GH secretion is unclear in humans. There is evidence that oral glucose (OG) administration initially decreases and subsequently stimulates GH secretion. Our aim was to study fasting GH concentrations and their response to OG administration in obese and healthy women and men, in order to elucidate the mechanism of sexual dimorphism of GH secretion and the possible contribution of ghrelin. We selected 33 women and 11 men as obese and healthy subjects. After an overnight fast, 75 g of oral glucose were administered; glucose, insulin, ghrelin, and PYY
1-36 were obtained at baseline and during 300 min. Fasting GH (μg/l) was higher in women than men; 1.3 ± 0.3 vs. 0.2 ± 0.1, p = 0.009, for women and men, respectively. The area under the curve between 0 and 150 min (AUC) of GH (μg/l · min) was higher in women than men; 98.2 ± 25.9 vs. 41.5 ± 28.6, p = 0.002, for women and men, respectively. The AUC of total ghrelin (pg/ml · min, mean ± SEM) between 0 and 150 min was borderline and significantly higher in women than men; 128 562.3 ± 8 335.9 vs. 98 839.1 ± 7 668.6, p = 0.069, for women and men, respectively. Several initial time points were higher in women than men. Glucose, insulin, and PYY1-36 were similar in women and men after OG. There were significant correlations between indices of post-oral glucose GH and ghrelin secretion. Fasting and initial GH secretion is higher in women than men, in contrast to peak and late GH secretion, which is similar in both cases. Sexual dimorphism in the regulation of GH secretion probably involves ghrelin. [ABSTRACT FROM AUTHOR]- Published

The mechanism of the altered GH secretion in obesity is unclear. There is evidence that oral glucose (OG) administration initially decreases and subsequently stimulates GH secretion. Ghrelin is a peptide that displays strong growth hormone-releasing activity. Its physiological importance on GH regulation is unclear. Our aim was to study fasting GH concentrations and their response to OG administration in relation with ghrelin secretion in obese and healthy women, in order to elucidate the hypothetical participation of ghrelin on post-oral glucose GH secretion. 36 women were included in the study. After an overnight fast, 75 g of oral glucose was administered; glucose, insulin, ghrelin, and PYY 1 – 36 were obtained at baseline and during 300 min. The area under the curve between 0 and 300 min (AUC) of GH μ/l·min) was lower in obese patients than in controls; 262.5 ± 57.5 vs. 534.9 ± 95.6, p = 0.01, for obese and controls respectively. GH peak (μg/l) was lower in obese patients than in controls; 3.7 ± 0.7 vs. 7.1 ± 1.0, p = 0.012, for obese and controls, respectively. The AUC of total ghrelin (pg/ml· min) was lower in obese patients than in controls; 233 032 ± 12 641 vs. 333 697 ± 29 877, p = 0.004, for the obese patients and controls respectively. PYY
1-36 was similar in obese and healthy women after OG. There were significant correlations between the diff erent indices of post-oral glucose GH and ghrelin secretion. These data suggest that ghrelin is a physiological regulator of GH in the post-oral glucose state, and the decreased ghrelin secretion could be one of the mechanisms responsible for the altered GH secretion in obesity.

- Abstract
Background. Ethnic differences in being overweight and obesity were studied among 18 year old males in Sweden. Method. This nationwide study was based on a record linkage between the Medical Birth Register, the Register of Military Induction Examinations and the Register of the Total Population. For 140,766 (87.8%) of the 160,247 males information was available on body mass index (BMI) and on their mothers' nationality. Results. After adjustment for education and geographical region the odds ratio for being overweight was found to be higher among 18 year old sons of immigrants from Finland (1.38 and 95% CI: 1.26-1.52) than among sons of Swedish mothers. Similarly, the odds ratio for being overweight was higher among the sons of immigrants from former Eastern Europe (1.68 and 96% CI: 1.46-1.94) than among sons of Swedish mothers. Conclusion. The risks of being overweight and obesity were increased among the sons of immigrants from Finland and former Eastern Europe compared to sons of Swedish mothers. [ABSTRACT FROM AUTHOR]

We present a 78-year-old woman with clinical acute hypopituitarism in whom pathologic findings showed lymphocytic hypophysitis and retroperitoneal fibrosis. Lymphocytic hypophysitis should be included in the differential diagnosis of hypopituitarism at any age. The association with idiopathic retroperitoneal fibrosis suggest an autoimmune origin for this entity. [ABSTRACT FROM AUTHOR]

Abstract Background Neuropeptide Y (NPY), agouti related peptide (AgRP), cocaine and amphetamine-regulated transcript (CART) and melanocortins, the products of the proopiomelanocortin (POMC), are hypothalamic peptides involved in feeding regulation and energy homeostasis. Recent evidence has demonstrated their expression in rat and human placenta. Methods In the current study, we have investigated the expression of those neuropeptides in the rat placenta by real-time PCR using a model of maternal food restriction. Results Our results showed that placental-derived neuropeptides were regulated through pregnancy and following food restriction. Conclusion These data could indicate that placental-derived neuropeptides represent a local regulatory circuit that may fine-tune control of energy balance during pregnancy.

31. A Non-Secreting Pituitary Adenoma That Changed to a Prolactinoma.

Santiago-Vazquez C, Palacios-Paino N, and Cordido F
- Abstract
Pituitary adenomas (PAs) are the third most common brain tumors in adults right after meningiomas and gliomas. Taking into account their hormonal activity in vivo, they can be divided in functioning PAs, which secrete hormones, and nonfunctioning pituitary adenomas (NFPAs), which are not associated with increased hormone secretion. We present the case of a man diagnosed with pituitary apoplexy. A transsphenoidal surgery was performed with subtotal removal of the mass. Pituitary hormones were measured before and after the procedure on several occasions, showing always normal PRL values, so he was diagnosed with a clinically NFPA. Two years later, the patient noticed a visual deficit. A new magnetic resonance imaging study was performed, showing adenomatous recurrence, and the patient underwent a new surgery. After this, hormonal evaluation revealed high levels of PRL on several occasions. After treatment with cabergoline was started, PRL levels normalized, the visual deficit improved, and there was a slight adenoma reduction. This case report represents an exception to the paradigm that in the presence of a macroadenoma and normal PRL levels (avoiding the "hook effect"), a prolactinoma can be discarded. Moreover, it stresses the importance of comprehensive, regular, and lifelong surveillance of patients with NFPAs and the close monitoring of serum PRL.

- Abstract
Aim: To investigate the impact of pituitary surgery on glucose metabolism and to identify predictors of remission of diabetes after pituitary surgery in patients with acromegaly., Methods: A national multicenter retrospective study of patients with acromegaly undergoing transsphenoidal surgery for the first time at 33 tertiary Spanish hospitals (ACRO-SPAIN study) was performed. Surgical remission of acromegaly was evaluated according to the 2000 and 2010 criteria., Results: A total of 604 acromegaly patients were included in the study with a total median follow up of 91 months (interquartile range [IQR] 45-163). At the acromegaly diagnosis, 23.8% of the patients had diabetes mellitus (DM) with a median glycated hemoglobin (HbA1c) of 6.9% (IQR 6.4-7.9) [51.9 mmol/mol (IQR 46.4-62.8)]. In the multivariate analysis, older age (odds ratio [OR] 1.02, 95% CI 1.00-1.05), dyslipidemia (OR 5.25, 95% CI 2.81 to 9.79), arthropathy (OR 1.39, 95% CI 2.82 to 9.79), and higher IGF-I levels (OR 1.30, 95% CI 1.05 to 1.60) were associated with a greater prevalence of DM. At the last follow-up visit after surgery, 21.1% of the DM patients (56.7% of them with surgical remission of acromegaly) experienced diabetes remission. The cure rate of DM was more common in older patients (hazard ratio [HR] 1.77, 95% CI 1.31 to 2.43), when surgical cure was achieved (HR 2.10, 95% CI 1.01 to 4.37) and when anterior pituitary function was not affected after surgery (HR 3.38, 95% CI 1.17 to 9.75)., Conclusion: Glucose metabolism improved in patients with acromegaly after surgery and 21% of the diabetic patients experienced diabetes remission; being more frequent in patients of older age, and those who experienced surgical cure and those with preserved anterior pituitary function after surgery., (© 2024.

- Abstract
Rathke's cleft cysts (RCC) are a common type of lesion found in the sellar or suprasellar area. They are usually monitored clinically, but in some cases, surgery may be required. However, their natural progression is not yet well understood, and the outcomes of surgery are uncertain. The objective of this study is to evaluate the natural history of Rathke's cleft cysts in patients who are clinically monitored without treatment, and to determine the outcomes of surgery and the incidence of recurrences over time., Design and Patients: National multicentric study of patients diagnosed of Rathke's cleft cyst (RCC- Spain) from 2000 onwards and followed in 15 tertiary centers of Spain. A total of 177 patients diagnosed of RCC followed for 67.3 months (6-215) and 88 patients who underwent surgery, (81 patients underwent immediate surgery after diagnosis and 7 later for subsequent growth) followed for 68.8 months (3-235)., Results: The cyst size remained stable or decreased in 73.5% (133) of the patients. Only 44 patients (24.3%) experienced a cyst increase and 9 of them (5.1%) experienced an increase greater than 3 mm. In most of the patients who underwent surgery headaches and visual alterations improved, recurrence was observed in 8 (9.1%) after a median time of 96 months, and no predictors of recurrence were discovered., Conclusions: Rathke's cleft cysts without initial compressive symptoms have a low probability of growth, so conservative management is recommended. Patients who undergo transsphenoidal surgery experience rapid clinical improvement, and recurrences are infrequent. However, they can occur after a long period of time, although no predictors of recurrence have been identified., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Menéndez-Torre, Gutiérrez-Hurtado, Ollero, Irigaray, Martín, Parra, González-Molero, Araujo-Castro, Idrobo, Moure, Molina, Biagetti, Iglesias, Paja, Villar-Taibo, Pena, Vicente, Guerrero-Pérez, Cordido, Aulinas, Mateu and Soto.)

- Abstract
Objective: The aim of this study is to compare the response to first-line medical treatment in treatment-naive acromegaly patients with pure growth hormone (GH)-secreting pituitary adenoma (GH-PA) and those with GH and prolactin cosecreting PA (GH&PRL-PA)., Design: This is a retrospective multicentric study of acromegaly patients followed from 2003 to 2023 in 33 tertiary Spanish hospitals with at least 6 months of first-line medical treatment., Methods: Baseline characteristics, first-line medical treatment strategies, and outcomes were analyzed. We employed a multiple logistic regression full model to estimate the impact of some baseline characteristics on disease control after each treatment modality., Results: Of the 144 patients included, 72.9% had a GH-PA, and 27.1% had a GH&PRL-PA. Patients with GH&PRL-PA were younger (43.9 ± 15.0 vs 51.9 ± 12.7 years, P < .01) and harboring more frequently macroadenomas (89.7% vs 72.1%, P = .03). First-generation somatostatin receptor ligand (fgSRL) as monotherapy was given to 106 (73.6%) and a combination treatment with fgSRL and cabergoline in the remaining 38 (26.4%). Patients with GH&PRL-PA received more frequently a combination therapy (56.4% vs 15.2%, P < .01). After 6 months of treatment, in the group of patients under fgSRL as monotherapy, those patients with GH&PRL-PA had worse control compared to GH-PAs (29.4% vs 55.1%, P = .04). However, these differences in the rate of disease control between both groups disappeared when both received combination treatment with fgSRL and cabergoline., Conclusion: In GH&PRL-PA, the biochemical control achieved with fgSRL as monotherapy is substantially worse than in patients harboring GH-PA, supporting the inclusion of cabergoline as first-line medical treatment in combination with fgSRLs in these subgroups of patients., Competing Interests: Conflict of interest: The authors declare no conflict of interest., (© The Author(s) 2024.

- Abstract
The objective of the study was to evaluate the efficacy of second-line therapies in patients with acromegaly caused by a growth hormone (GH) and prolactin (PRL) co-secreting pituitary neuroendocrine tumor (GH&PRL-Pit-NET) compared to their efficacy in patients with acromegaly caused by a GH-secreting pituitary neuroendocrine tumor (GH-Pit-NET). This is a multicenter retrospective study of patients with acromegaly on treatment with pasireotide and/or pegvisomant. Patients were classified in two groups: GH&PRL-Pit-NETs when evidence of hyperprolactinemia and immunohistochemistry (IHC) for GH and PRL was positive or if PRL were >200 ng/dL regardless of the PRL-IHC and GH-Pit-NETs when the previously mentioned criteria were not met. A total of 28 cases with GH&PRL-Pit-NETs and 122 with GH-Pit-NETs met the inclusion criteria. GH&PRL-Pit-NETs presented at a younger age, caused hypopituitarism, and were invasive more frequently than GH-Pit-NETs. There were 124 patients treated with pegvisomant and 49 with pasireotide at any time. The efficacy of pegvisomant for IGF-1 normalization was of 81.5% and of pasireotide of 71.4%. No differences in IGF-1 control with pasireotide and with pegvisomant were observed between GH&PRL-Pit-NETs and GH-Pit-NETs. All GH&PRL-Pit-NET cases treated with pasireotide (n = 6) and 82.6% (n = 19/23) of the cases treated with pegvisomant normalized PRL levels. No differences in the rate of IGF-1 control between pegvisomant and pasireotide were detected in patients with GH&PRL-Pit-NETs (84.9% vs 66.7%, P = 0.178). We conclude that despite the more aggressive behavior of GH&PRL-Pit-NETs than GH-Pit-NETs, no differences in the rate of IGF-1 control with pegvisomant and pasireotide were observed between both groups, and both drugs have shown to be effective treatments to control IGF-1 and PRL hypersecretion in these tumors.

- Abstract
Purpose: To evaluate differences in clinical presentation and in surgical outcomes between growth hormone-secreting pituitary adenomas (GH-PAs) and GH and prolactin co-secreting pituitary adenomas (GH&PRL-PAs)., Methods: Multicenter retrospective study of 604 patients with acromegaly submitted to pituitary surgery. Patients were classified into two groups according to serum PRL levels at diagnosis and immunohistochemistry (IHC) for PRL: a) GH&PRL-PAs when PRL levels were above the upper limit of normal and IHC for GH and PRL was positive or PRL levels were >100ng/and PRL IHC was not available (n=130) and b) GH-PAs who did not meet the previously mentioned criteria (n=474)., Results: GH&PRL-PAs represented 21.5% (n=130) of patients with acromegaly. The mean age at diagnosis was lower in GH&PRL-PAs than in GH-PAs (P<0.001). GH&PRL-PAs were more frequently macroadenomas (90.6% vs. 77.4%, P=0.001) and tended to be more invasive (33.6% vs. 24.7%, P=0.057) than GH-PAs. Furthermore, they had presurgical hypopituitarism more frequently (OR 2.8, 95% CI 1.83-4.38). IGF-1 upper limit of normality (ULN) levels at diagnosis were lower in patients with GH&PRL-PAs (median 2.4 [IQR 1.73-3.29] vs. 2.7 [IQR 1.91-3.67], P=0.023). There were no differences in the immediate (41.1% vs 43.3%, P=0.659) or long-term post-surgical acromegaly biochemical cure rate (53.5% vs. 53.1%, P=0.936) between groups. However, there was a higher incidence of permanent arginine-vasopressin deficiency (AVP-D) (7.3% vs. 2.4%, P=0.011) in GH&PRL-PAs patients., Conclusions: GH&PRL-PAs are responsible for 20% of acromegaly cases. These tumors are more invasive, larger and cause hypopituitarism more frequently than GH-PAs and are diagnosed at an earlier age. The biochemical cure rate is similar between both groups, but patients with GH&PRL-PAs tend to develop permanent postsurgical AVP-D more frequently., (© The Author(s) 2024.

- Abstract
Background: Little is known about the relationship between signal intensity patterns on T2-weighted magnetic resonance imaging (MRI) in non-functioning pituitary adenomas (NFPAs)., Objective: In this study, the clinical, hormonal, histological features, and therapeutic responses were evaluated according to the T2 signal intensity in NFPAs., Methods: This retrospective and multicenter study included a group of 166 NFPA patients (93 men, 56%, mean age 58.5 ±14.8 yr)., Results: Approximately half of the tumors (n=84, 50.6%) were hyperintense, while 34.3% (n=57) and 15.1% (n=25) were iso- and hypointense, respectively. The median maximum tumor diameter of the isointense group [16 (13-25) mm] was significantly lower than that of the hyperintense [23 (16.6-29.7) mm] group (p=0.003). Similarly, the tumor volume of the isointense group [1,523 (618-5,226) mm
3 ] was significantly lower than that of the hyperintense [4,012 (2,506-8,320) mm3 ] group (p=0.002). Chiasmatic compression occurred less frequently in tumors with isointense signal characteristics (38.6%) compared to tumors with hypointense (68%) and hyperintense (65.5%) signal characteristics (p=0.003). Invasive adenomas (p=0.001) and the degree of cavernous sinus invasion (p<0.001) were more frequent in the hyperintense adenoma group compared to the remaining groups. Plurihormonal tumors and silent lactotroph adenomas were more frequent in the isointense tumor group., Conclusion: In conclusion, hyperintensity on T2-weighted MRI in NFPAs is associated with larger and more invasive tumors compared to isointense NFPAs., Competing Interests: The authors declare that they have no conflict of interest., (Thieme.

- Abstract
Context: There are no data on mortality of acromegaly diagnosed in older individuals., Objective: This work aimed to compare clinical characteristics, growth hormone-related comorbidities, therapeutic approaches, and mortality rate of patients diagnosed before or after 2010 and to assess overall mortality rate compared with the general Spanish population., Methods: A retrospective evaluation was conducted among Spanish tertiary care centers of 118 patients diagnosed with acromegaly at age 65 or older. Kaplan-Meier curves were constructed to trace survival, and Cox proportional hazard models were used to assess the risk factors associated with mortality. We also compared mortality with that of the Spanish population by using age- and sex-adjusted standardized mortality ratios (SMRs)., Results: No differences were found in first-line treatment or biochemical control, between both periods except for faster biochemical control after 2010. Twenty-nine (24.6%) patients died, without differences between groups, and had a median of follow-up 8.6 years (103, [72.3] months). Overall SMR was 1.02 (95% CI, 0.57-1.54), (0.60; 95% CI, 0.35-1.06) for men and (1.80; 95% CI, 1.07-2.94) for women. The most common cause of death was cardiovascular disease (CVD)., Conclusion: The mortality in patients with acromegaly diagnosed in older individuals was no different between both periods, and there was no overall SMR difference compared with the general Spanish population. However, the SMR was higher in women. As CVD is the leading cause of mortality, it seems advisable to initiate an intense CVD protective treatment as soon as acromegaly is diagnosed, particularly in women, in addition to tight acromegaly control to prevent excess mortality., (© The Author(s) 2023.

- Abstract
The term hypophysitis is used to designate a heterogeneous group of pituitary conditions characterized by the presence of inflammatory infiltration of the adenohypophysis, neurohypophysis, or both. Although hypophysitis are rare disorders, the most common in clinical practice is lymphocytic hypophysitis, a primary hypophysitis characterized by lymphocytic infiltration, which predominantly affects women. Other forms of primary hypophysitis are associated with different autoimmune diseases. Hypophysitis can also be secondary to other disorders such as sellar and parasellar diseases, systemic diseases, paraneoplastic syndromes, infections, and drugs, including immune checkpoint inhibitors. The diagnostic evaluation should always include pituitary function tests and other analytical tests based on the suspected diagnosis. Pituitary magnetic resonance imaging is the investigation of choice for the morphological assessment of hypophysitis. Glucocorticoids are the mainstay of treatment for most symptomatic hypophysitis., (Copyright © 2023 SEEN and SED. Published by Elsevier España, S.L.U. All rights reserved.)

- Abstract
microRNAs (miRNAs) are a class of small endogenous RNA that play pivotal roles in both the differentiation and function of adipocytes during the development of obesity. Despite this, only a few miRNA families have been identified as key players in adipogenesis. Here, we show the relevance of the miR-19 family, miR-19a and miR-19b, in lipid accumulation and the expansion of the adipose tissue in obesity. We observed that miR-19s were upregulated in the abdominal subcutaneous adipose tissue (aSAT) of human patients with morbid obesity, whereas after bariatric surgery, their expression was reduced. In vitro experiments identified miR-19a and b as crucial actors in adipogenesis and lipid accumulation. Overall, our results suggest a novel role of the miR-19 family in the regulatory networks underlying adipogenesis and, therefore, adipose tissue dysfunction.

- Abstract
Background: In recent years, dopamine agonists (DAs) have become an attractive therapeutic option to prevent both tumor growth and post-surgical tumor remnant growth in clinically non-functioning pituitary adenoma (NFPA)., Aim: To analyze our experience on the effect of cabergoline (CAB) on tumor remnant after initial surgery in NFPA patients., Patients and Methods: A retrospective and multicenter study of NFPA patients with tumor remnant after surgery treated with CAB was performed., Results: From a total of 142 NFPA patients (79 men, 55.2%; mean age 57.2 ± 14.2 year) who underwent surgery, we selected 62/142 (43.7%) patients (32 men, 51.6%; mean age 59.3 ± 13.9 year) with tumor persistence (TP) after surgery. In 22/62 (35.5%) TP patients CAB was used (CAB group), while the rest of the patients (40/62, 64.5%) underwent active surveillance [observation (OBS) group)]. The maximum diameter of the tumor remnant did not change significantly in either the CAB group [11.5 (6.0-16.9) mm vs. 12.0 (7.0-15.0) mm, p = 0.85) or the OBS group [8.5 (6.0-13.7) mm vs. 9.0 (6.2-14.0) mm, p = 0.064) at the end of the follow-up [13 (10.5-17) vs. 77.5 (50.2-107.2) months, CAB vs. OBS group; p < 0.001]. At the end of the treatment period with CAB most of the patients (n = 20/22, 90.9%) showed no progression of the tumor remnant [stable disease, SD (n = 17/22, 77.2%) and partial response, PR (n = 3/22, 13.6%)], while 2/22 patients (9.1%) exhibited progression. Similar response rates were observed in the OBS group [SD (n = 32/40, 80%), PR (n = 2/40, 5%), and progression (n = 6/40, 15%)]. Although no statistically significant differences (p = 0.42) were found in these responses, the percentage of progression was 1.65 times higher in the OBS group compared to the CAB group. On the contrary, the percentage of PR was 2.72 times higher in the CAB group compared to the OBS group, despite a significantly shorter follow-up period in the CAB group., Conclusion: Although the present study showed no significant differences in the type of tumor response between the CAB and OBS groups of patients, the percentage of PR was higher and that of progression lower in the CAB group compared to the OBS group. This finding does not rule out a potential therapeutic benefit of CAB in the management of tumor remnant in patients with NFPA undergoing surgery., (© 2022.

- Abstract
Context: Some reports suggest that acromegaly in elderly patients has a more benign clinical behavior and could have a better response to first-generation long-acting somatostatin receptor ligands (SRL). However, there is no specific therapeutic protocol for this special subgroup of patients., Objective: This study aimed at identifying predictors of response to SRL in elderly patients., Design: Multicentric retrospective nationwide study of patients diagnosed with acromegaly at or over the age of 65 years., Results: One-hundred and eighteen patients (34 men, 84 women, mean age at diagnosis 71.7 ± 5.4 years old) were included. Basal insulin-like growth factor type 1 (IGF-1) above the upper limit of normal (ULN) and growth hormone (GH) levels (mean ± SD) were 2.7 ± 1.4 and 11.0 ± 11.9 ng/ml, respectively. The mean maximal tumor diameter was 12.3 ± 6.4 mm, and up to 68.6% were macroadenoma. Seventy-two out of 118 patients (61.0%) underwent surgery as primary treatment. One-third of patients required first-line medical treatment due to a rejection of surgical treatment or non-suitability because of high surgical risk. After first-line surgery, 45/72 (63.9%) were in disease remission, and 16/34 (46.7%) of those treated with SRL had controlled disease. Patients with basal GH at diagnosis ≤6 ng/ml had lower IGF-1 levels and had smaller tumors, and more patients in this group reached control with SRL (72.7% vs. 33.3%; p < 0.04) [OR: 21.3, IC: 95% (2.4-91.1)], while male patients had a worse response [OR: 0.09, IC 95% (0.01-0.75)]. The predictive model curve obtained for SRL response showed an AUC of 0.82 CI (0.71-0.94)., Conclusions: The most frequent phenotype in newly diagnosed acromegaly in the elderly includes small adenomas and moderately high IGF-1 levels. GH at diagnosis ≤6 ng/ml and female gender, but not age per se , were associated with a greater chance of response to SRL., Competing Interests: BB, MP, AV, CA-E, AV, RC, IB, SG, FC, SW, and MP-D have received consulting fees or research support or participated in clinical trials supported by from Pfizer, Ipsen, Quiasma, and/or Recordati.

- Abstract
Context: Ectopic acromegaly is a consequence of rare neuroendocrine tumors (NETs) that secrete GHRH. This abnormal GHRH secretion drives GH and IGF-1 excess, with a clinical presentation similar to classical pituitary acromegaly. Identifying the underlying cause for the GH hypersecretion in the setting of ectopic GHRH excess is, however, essential for proper management both of acromegaly and the NET. Owing to the rarity of NETs, the imaging characteristics of the pituitary in ectopic acromegaly have not been analyzed in depth in a large series., Objective: Characterize pituitary magnetic resonance imaging (MRI) features at baseline and after NET treatment in patients with ectopic acromegaly., Design: Multicenter, international, retrospective., Setting: Tertiary referral pituitary centers., Patients: Thirty ectopic acromegaly patients having GHRH hypersecretion., Intervention: None., Main Outcome Measure: MRI characteristics of pituitary gland, particularly T2-weighted signal., Results: In 30 patients with ectopic GHRH-induced acromegaly, we found that most patients had hyperplastic pituitaries. Hyperplasia was usually moderate but was occasionally subtle, with only small volume increases compared with normal ranges for age and sex. T2-weighted signal was hypointense in most patients, especially in those with hyperplastic pituitaries. After treatment of the NET, pituitary size diminished and T2-weighted signal tended to normalize., Conclusions: This comprehensive study of pituitary MRI characteristics in ectopic acromegaly underlines the utility of performing T2-weighted sequences in the MRI evaluation of patients with acromegaly as an additional tool that can help to establish the correct diagnosis., (© The Author(s) 2022.

44. Thyroid Function Alteration in Obesity and the Effect of Bariatric Surgery.

Cordido M, Juiz-Valiña P, Urones P, Sangiao-Alvarellos S, and Cordido F
- Abstract
The most common endocrine disease in obesity is hypothyroidism and secondary endocrine alterations, including abnormal thyroid function, are frequent in obesity. It is unclear whether impaired thyroid function is the cause or the consequence of increased adiposity; furthermore, there are no clear data regarding the best way to dose levothyroxine for patients with both hypothyroidism and obesity, and the effect of bariatric surgery (BS). The aim of the present article is to review some controversial aspects of the relation between obesity and the thyroid: (1) Thyroid function in obesity and the effect of BS (2) Thyroid hormone treatment (THT) in obese patients with hypothyroidism and the effect of BS. In summary: In morbidly obese patients, TSH is moderately increased. Morbid obesity has a mild central resistance to the thyroid hormone, reversible with weight loss. In morbidly obese hypothyroid patients, following weight loss, the levothyroxine dose/kg of ideal weight did not change, albeit there was an increment in the levothyroxine dose/kg of actual weight. From a clinical practice perspective, in morbid obesity, diagnosing mild hypothyroidism is difficult, BS improves the altered thyroid function and THT can be adapted better if it is based on ideal weight.

- Abstract
The most frequent endocrine disease in obese patients is hypothyroidism. To date, there are no clear data regarding what happens to the dose of levothyroxine (LT4) after bariatric surgery (BS). The objective of the present study was to evaluate thyroid hormone replacement dose in morbidly obese hypothyroid patients after BS-induced weight loss. We explore the best type of measured or estimated body weight for LT4 dosing. We performed an observational study evaluating patients with morbid obesity and hypothyroidism who underwent BS. We included 48 patients (three men). In morbidly obese hypothyroid patients 12 months after BS-induced weight loss, the total LT4 dose or the LT4 dose/kg ideal body weight did not change, while there was a significant increase in LT4 dose/body surface area, LT4 dose/kg weight, LT4 dose/kg adjusted body weight, LT4 dose/kg body fat, and LT4 dose/kg lean body weight. There were no differences in LT4 dose and its variation between sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB). The present study strongly suggests that LT4 dosing in obese hypothyroid patients can be individually adapted more precisely if it is based on ideal body weight.

- Abstract
Background: Giant pituitary adenoma (≥4 cm) is a rare tumor whose clinical features and prognosis are not well known., Aim: To evaluate the clinical characteristics and therapeutic outcomes of giant non-functioning PA (gNFPA)., Patients and Methods: A retrospective multicenter study of gNFPA patients diagnosed in a 12-year period was performed. In each patient, clinical data and therapeutic outcomes were registered., Results: Forty patients (24 men, age 54.2 ± 16.2 years) were studied. The maximum tumor diameter [median (interquartile range)] was 4.6 cm (4.1-5.1). Women had larger tumors [4.8 cm (4.2-5.4) vs. 4.5 cm (4.0-4.9); p=0.048]. Hypopituitarism [partial (n=22, 55%) or complete (n=9, 22.5%)] at diagnosis was present in 77.5% of the patients. Visual field defects were found in 90.9%. The most used surgical technique was endoscopic endonasal transsphenoidal (EET) surgery (n=31, 77.5%). Radiotherapy was used in 11 (27.5%) patients (median dose 50.4 Gy, range 50-54). Thirty-seven patients were followed for 36 months (10-67 months). Although more than half of these patients showed tumor persistence (n=25, 67.6%), tumor size was significantly reduced [0.8 cm (0-2.5); p<0.001]. At last visit, 12 patients (32.4%) showed absence of tumor on MRI. Hypopituitarism rate was similar (75.0%), although with significant changes (p<0.001) in the distribution of the type of hypopituitarism. The absence of tumor at the last visit was positively associated with positive immunohistochemical staining for FSH (p=0.01) and LH (p=0.006) and negatively with female sex (p=0.011), cavernous sinus invasion (p=0.005) and the presence of Knosp grade 4 (p=0.013)., Conclusion: gNFPAs are more frequent in men but tumors are larger in women. Surgical treatment is followed by a complete tumor resection rate of approximately 30%. Positive immunostaining for gonadotropins is associated with tumor absence at last revision, while female sex and invasion of the cavernous sinuses with tumor persistence., Competing Interests: Authors declare that they have no conflict of interest., (Thieme.

- Abstract
Background: Craniopharyngioma (CP) is a rare tumor in the elderly whose clinical features and prognosis are not well known in this population., Aim: To evaluate the clinicopathological features and therapeutic outcomes of CP diagnosed in the elderly., Patients and Methods: This was a retrospective, multicenter, national study of CP patients diagnosed over the age of 65 years and surgically treated., Results: From a total of 384 adult CP patients, we selected 53 (13.8%) patients (27 women [50.9%], mean age 72.3 ± 5.1 years [range 65-83 years]) diagnosed after the age of 65 years. The most common clinical symptoms were visual field defects (71.2%) followed by headache (45.3%). The maximum tumor diameter was 2.9 ± 1.1 cm. In most patients, the tumor was suprasellar (96.2%) and mixed (solid-cystic) (58.5%). The surgical approach most commonly used was transcranial surgery (52.8%), and more than half of the patients (54.7%) underwent subtotal resection (STR). Adamantinomatous CP and papillary CP were present in 51 and 45.1%, respectively, with mixed forms in the remaining. Surgery was accompanied by an improvement in visual field defects and in headaches; however, pituitary hormonal hypofunction increased, mainly at the expense of an increase in the prevalence of diabetes insipidus (DI) (from 3.9 to 69.2%). Near-total resection (NTR) was associated with a higher prevalence of DI compared with subtotal resection (87.5 vs. 53.6%, p = 0.008). Patients were followed for 46.7 ± 40.8 months. The mortality rate was 39.6% with a median survival time of 88 (95% CI: 57-118) months. DI at last visit was associated with a lower survival., Conclusion: CP diagnosed in the elderly shows a similar distribution by sex and histologic forms than that diagnosed at younger ages. At presentation, visual field alterations and headaches are the main clinical symptoms which improve substantially with surgery. However, surgery, mainly NTR, is accompanied by worsening of pituitary function, especially DI, which seems to be a predictor of mortality in this population., (© 2020 S. Karger AG, Basel.)

- Abstract
Purpose: Recent data indicate that extended dosing intervals (EDIs) with lanreotide autogel 120 mg are effective and well-received among patients with acromegaly who have achieved biochemical control with monthly injections of long-acting somatostatin analogues (SSAs). We further evaluated the effectiveness of lanreotide autogel 120 mg delivered at EDIs (>4 weeks) in routine clinical practice., Methods: Cross-sectional, multicentre, observational study conducted to determine the effectiveness-measured by control of serum insulin-like growth factor 1 (IGF-1)-of lanreotide autogel 120 mg at dosing intervals >4 weeks for ≥6 months in selected patients with acromegaly treated in routine clinical practice (NCT02807233). Secondary assessments included control of growth hormone (GH) levels, treatment adherence, patient satisfaction, and quality of life (QoL) using validated questionnaires (EQ-5D, AcroQoL, and TSQM-9). Patients who received radiotherapy within the last 6 months were excluded., Results: Among 109 patients evaluated, mean (SD) age was 59.1 (13.2) years. IGF-1 values were normal (mean [SD]: 175.0 [74.5], 95% CI: 160.8 -189.1) in 91.7% of cases and normal in 91.4% of patients without previous radiotherapy treatment (n = 81). GH levels were ≤2.5 and ≤1 ng/mL, respectively, in 80.6% and 58.3%. Most patients were treated either every 5-6 (57.8%) or 7-8 weeks (38.5%), with 2.8% treated greater than every 8 weeks. The mean AcroQoL score was 63.0 (20.1). The mean global treatment satisfaction score (TSQM-9) was 75.1 (16.6). Treatment adherence (defined as no missed injections) was 94.5%., Conclusion: Lanreotide autogel 120 mg at intervals of >4 weeks provided IGF-1 control in more than 90% of patients with acromegaly. Treatment satisfaction and adherence were good. These findings support use of extended dosing intervals in patients who have achieved good biochemical control with long-acting SSAs.

- Abstract
Introduction: Bariatric surgery offers the most effective treatment for obesity, ameliorating or even reverting associated metabolic disorders, such as type 2 diabetes. We sought to determine the effects of bariatric surgery on circulating microRNAs (miRNAs) that have been implicated in the metabolic cross talk between the liver and adipose tissue., Research Design and Methods: We measured 30 miRNAs in 155 morbidly obese patients and 47 controls and defined associations between miRNAs and metabolic parameters. Patients were followed up for 12 months after bariatric surgery. Key findings were replicated in a separate cohort of bariatric surgery patients with up to 18 months of follow-up., Results: Higher circulating levels of liver-related miRNAs, such as miR-122, miR-885-5 p or miR-192 were observed in morbidly obese patients. The levels of these miRNAs were positively correlated with body mass index, percentage fat mass, blood glucose levels and liver transaminases. Elevated levels of circulating liver-derived miRNAs were reversed to levels of non-obese controls within 3 months after bariatric surgery. In contrast, putative adipose tissue-derived miRNAs remained unchanged (miR-99b) or increased (miR-221, miR-222) after bariatric surgery, suggesting a minor contribution of white adipose tissue to circulating miRNA levels. Circulating levels of liver-derived miRNAs normalized along with the endocrine and metabolic recovery of bariatric surgery, independent of the fat percentage reduction., Conclusions: Since liver miRNAs play a crucial role in the regulation of hepatic biochemical processes, future studies are warranted to assess whether they may serve as determinants or mediators of metabolic risk in morbidly obese patients., Competing Interests: Competing interests: PW, SK and MM are named inventors on a licensed patent held by Medical University Innsbruck and King’s College London for the use of miR-122 as a biomarker of metabolic risk (EP2430453B1, US8546089, EP15193448.6). MM filed and licensed patent applications on miRNAs as biomarkers (EP2776580 B1, DE112013006129T5, GB2524692A, EP2576826 B, JP2013-513740).
