Differences between GH and PRL co-secreting and GH-secreting pituitary adenomas. A series of 604 cases.

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.

Primary Cilia as a Tumor Marker in Pituitary Neuroendocrine Tumors.

Pituitary neuroendocrine tumors (PitNETs) account for approximately 15% of all intracranial neoplasms. Although they usually appear to be benign, some tumors display worse behavior, displaying rapid growth, invasion, refractoriness to treatment, and recurrence. Increasing evidence supports the role of primary cilia (PC) in regulating cancer development. Here, we showed that PC are significantly increased in PitNETs and are associated with increased tumor invasion and recurrence. Serial electron micrographs of PITNETs demonstrated different ciliation phenotypes (dot-like versus normal-like cilia) that represented PC at different stages of ciliogenesis. Molecular findings demonstrated that 123 ciliary-associated genes (eg, doublecortin domain containing protein 2, Sintaxin-3, and centriolar coiled-coil protein 110) were dysregulated in PitNETs, representing the upregulation of markers at different stages of intracellular ciliogenesis. Our results demonstrate, for the first time, that ciliogenesis is increased in PitNETs, suggesting that this process might be used as a potential target for therapy in the future.

Risk factors for intraoperative hypertensive crisis in patients with pheochromocytomas and sympathetic paragangliomas.

PURPOSE: To identify presurgical and surgical risk factors for intraoperative hypertensive crisis in patients with pheochromocytomas and sympathetic paragangliomas (PGLs) (PPGLs). METHODS: Retrospective multicenter cohort study of patients with PPGLs from 18 tertiary hospitals. Intraoperative hypertensive crisis was defined as systolic blood pressure (SBP) greater than 200 mmHg lasting more than 1 min and postoperative hypertensive crisis as SBP greater than 180 mmHg or diastolic blood pressure (DBP) greater than 110 mmHg. RESULTS: A total of 296 surgeries were included. Alpha presurgical blockade was employed in 93.2% of the cases and beta-adrenergic in 53.4%. Hypertensive crisis occurred in 20.3% ( n  = 60) of the surgeries: intraoperative crisis in 56 and postoperative crisis in 6 cases (2 cases had both types of crises). We identified as risk factors of intraoperative hypertensive crisis, absence of presurgical glucocorticoid therapy (odds ratio [OR] 3.48; 95% confidence interval [CI] 1.19-10.12) higher presurgical SBP (OR 1.22 per each 10 mmHg, 95% CI 1.03-1.45), a larger tumor size (OR 1.09 per each 10 mm, 95% CI 1.00-1.19) and absence of oral sodium repletion (OR 2.59, 95% CI 1.25-5.35). Patients with hypertensive crisis had a higher rate of intraoperative bleeding ( P  < 0.001), of intraoperative hemodynamic instability ( P  < 0.001) and of intraoperative hypotensive episodes ( P  < 0.001) than those without hypertensive crisis. CONCLUSION: Intraoperative hypertensive crisis occurs in up to 20% of the PPGL resections. Patients not pretreated with glucocorticoid therapy before surgery, with larger tumors and higher presurgical SBP and who do not receive oral sodium repletion have a higher risk for developing hypertensive crisis during and after PPGL surgery.

Local recurrence and metastatic disease in pheochromocytomas and sympathetic paragangliomas.

Purpose: To evaluate the rate of recurrence among patients with pheochromocytomas and sympathetic paragangliomas (PGLs; together PPGLs) and to identify predictors of recurrence (local recurrence and/or metastatic disease). Methods: This retrospective multicenter study included information of 303 patients with PPGLs in follow-up in 19 Spanish tertiary hospitals. Recurrent disease was defined by the development of local recurrence and/or metastatic disease after initial complete surgical resection. Results: A total of 303 patients with PPGLs that underwent 311 resections were included (288 pheochromocytomas and 15 sympathetic PGLs). After a median follow-up of 4.8 years (range 1-19), 24 patients (7.9%) had recurrent disease (3 local recurrence, 17 metastatic disease and 4 local recurrence followed by metastatic disease). The median time from the diagnosis of the PPGL to the recurrence was of 11.2 months (range 0.5-174) and recurrent disease cases distributed uniformly during the follow-up period. The presence of a pathogenic variant in SDHB gene (hazard ratio [HR] 13.3, 95% CI 4.20-41.92), higher urinary normetanephrine levels (HR 1.02 per each increase in standard deviation, 95% CI 1.01-1.03) and a larger tumor size (HR 1.01 per each increase in mm, 95% CI 1.00-1.02) were independently associated with disease recurrence. Conclusion: The recurrence of PPGLs occurred more frequently in patients with SDHB mutations, with larger tumors and with higher urinary normetanephrine levels. Since PPGL recurrence may occur at any time after the initial PPGL diagnosis is performed, we recommend performing a strict follow-up in all patients with PPGLs, especially in those patients with a higher risk of recurrent disease.

Autonomous cortisol secretion in patients with primary aldosteronism: prevalence and implications on cardiometabolic profile and on surgical outcomes.

Purpose: The aim of this study was to evaluate the prevalence of autonomous cortisol secretion (ACS) in patients with primary aldosteronism (PA) and its implications on cardiometabolic and surgical outcomes. Methods: This is a retrospective multicenter study of PA patients who underwent 1 mg dexamethasone-suppression test (DST) during diagnostic workup in 21 Spanish tertiary hospitals. ACS was defined as a cortisol post-DST >1.8 µg/dL (confirmed ACS if >5 µg/dL and possible ACS if 1.8-5 µg/dL) in the absence of specific clinical features of hypercortisolism. The cardiometabolic profile was compared with a control group with ACS without PA (ACS group) matched for age and DST levels. Results: The prevalence of ACS in the global cohort of patients with PA (n = 176) was 29% (ACS-PA; n = 51). Ten patients had confirmed ACS and 41 possible ACS. The cardiometabolic profile of ACS-PA and PA-only patients was similar, except for older age and larger tumor size of the adrenal lesion in the ACS-PA group. When comparing the ACS-PA group (n = 51) and the ACS group (n = 78), the prevalence of hypertension (OR 7.7 (2.64-22.32)) and cardiovascular events (OR 5.0 (2.29-11.07)) was higher in ACS-PA patients than in ACS patients. The coexistence of ACS in patients with PA did not affect the surgical outcomes, the proportion of biochemical cure and clinical cure being similar between ACS-PA and PA-only groups. Conclusion: Co-secretion of cortisol and aldosterone affects almost one-third of patients with PA. Its occurrence is more frequent in patients with larger tumors and advanced age. However, the cardiometabolic and surgical outcomes of patients with ACS-PA and PA-only are similar.

Mortality in Acromegaly Diagnosed in Older Individuals in Spain Is Higher in Women Compared to the General Spanish Population.

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.

Executive summary of the consensus document on hypophysitis of the Neuroendocrinology Area of Knowledge of the Spanish Society of Endocrinology and Nutrition.

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.

Genetic Study in Pheochromocytoma: Is It Possible to Stratify the Risk of Hereditary Pheochromocytoma?

INTRODUCTION: It is estimated that 30-40% of patients with apparently sporadic pheochromocytomas (PHEOs) have an inherited predisposition syndrome. The aim of our study was to develop a predictive model of hereditary PHEO based on the clinical, hormonal, and radiological features present at the diagnosis of patients with PHEOs. METHODS: A retrospective multicenter cohort study of patients with PHEOs with available genetic study from 18 tertiary hospitals. Clinical, biochemical, and radiological features were used to build a multivariate logistic regression model. The estimation of all possible equations was used to select the model with the best diagnostic accuracy (lower Akaike index). RESULTS: A total of 245 patients were included: 169 (69.0%) patients with sporadic PHEOs and 76 (31%) with hereditary PHEOs. The parsimonious predictive model with the highest diagnostic accuracy for the prediction of hereditary PHEO combined the variables age, non-cardiovascular disease, urinary norepinephrine levels, and tumor size. The area under the ROC curve of this model was 0.800 (0.705-0.887). Based on the predictive model, the probability of hereditary PHEO in patients older than 60 years with cardiovascular disease, high levels of urinary norepinephrine and unilateral PHEOs >60 mm was <2%. And if the age was above 80 years, lower than 1%. The probability of sporadic PHEO linearly increased with age (MH Test for linear Trend: χ2 (1) = 30.05; p < 0.001). CONCLUSION: In certain populations such as old patients with cardiovascular disease, with high levels of urinary norepinephrine and large tumors in which the probability of hereditary PHEO is very low, genetic testing could be avoided in the absence of specific suspicion.

Factors associated with therapeutic response in acromegaly diagnosed in the elderly in Spain.

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.

Glycemic disorders in patients with pheochromocytomas and sympathetic paragangliomas.

The objective of our study was to determine the prevalence of glycemic disorders (diabetes mellitus and prediabetes) in patients with pheochromocytomas and sympathetic paragangliomas (PPGLs) and identify risk factors for their development and the likelihood of their resolution after surgery. A multicentric retrospective study of patients with PPGLs submitted to surgery between 2000 and 2021 in 17 Spanish hospitals was performed. Diabetes-specific data were collected at diagnosis, in the immediate- and long-term postsurgical follow-up. A total of 229 patients with PPGLs were included (218 with pheochromocytomas and 11 with sympathetic paragangliomas). Before surgery, glycemic disorders were diagnosed in 35.4% of the patients (n = 81): 54 with diabetes and 27 with prediabetes. The variables independently associated with a higher risk of glycemic disorders were sporadic PPGL (odds ratio (OR) = 3.26 (1.14-9.36)) and hypertension (OR = 3.14 (1.09-9.01)). A significant decrease in fasting plasma glucose and HbA1c levels was observed after surgery, in the short-term and long-term follow-up (P < 0.001). After a median follow-up of 48.5 months (range 3.3-168.9), after surgery, 52% of diabetic and 68% of prediabetic patients experienced a complete resolution. Lower body mass index (BMI) (P = 0.001), lower glucose levels (P = 0.047) and shorter duration of diabetes prior to surgery (P = 0.021) were associated with a higher probability of diabetes resolution. In conclusion, glycemic disorders in patients with PPGLs are present in more than a third of them at diagnosis. Sporadic PPGLs and hypertension are risk factors for their development. More than 50% of cases experience a complete resolution of the glycemic disorder after resection of the PPGLs.

Differences in the presentation and evolution of primary aldosteronism in elderly (≥65 years) and young patients (<65 years).

Objective: To compare the presentation and evolution of primary aldosteronism (PA) in the elderly (≥65 years) and young patients (<65 years). Methods: A retrospective multicenter study was performed in 20 Spanish hospitals of PA patients in follow-up between 2018 and 2021. Results: Three hundred fifty-two patients with PA <65 years and 88 patients ≥65 years were included. Older PA patients had a two-fold higher prevalence of type 2 diabetes, dyslipidemia, and cerebrovascular disease, but these differences disappeared after adjusting for hypertension duration. At diagnosis, diastolic blood pressure was lower than in young patients (83.3 ± 11.54 vs 91.6 ± 14.46 mmHg, P < 0.0001). No differences in the rate of overall correct cannulation (56.5% vs 42.3%, P = 0.206) or the diagnosis of unilaterality (76.9% vs 62.5%, P = 0.325) in the adrenal venous sampling (AVS) was observed between the elderly and young groups. However, there was a lower proportion of PA patients who underwent adrenalectomy in the elderly group than in the younger group (22.7% (n = 20) vs 37.5% (n = 132), P = 0.009). Nevertheless, no differences in the rate of postsurgical biochemical (100% (n = 14) vs 92.8% (n = 90), P = 0.299) and hypertension cure (38.6% (n = 51) vs 25.0% (n = 5), P = 0.239) were observed between both groups. Conclusion: Older patients with PA have a worse cardiometabolic profile than young patients with PA that it is related to a longer duration of hypertension. However, the results of the AVS, and adrenalectomy are similar in both groups. Therefore, the management of elderly patients with PA should be based not only on age, but rather on the overall medical, physical, social, and mental characteristics of the patients.

Craniopharyngioma in the Elderly: A Multicenter and Nationwide Study in Spain.

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.

Craniopharyngiomas: A clinicopathological and molecular study of 52 cases - Experience in the Complejo Hospitalario de Toledo and Hospital Universitario 12 de Octubre (Madrid).

Craniopharyngiomas (CPs) are histologically benign tumors that are associated with high levels of morbidity. Two clinicopathological variants - adamantinomatous (ACP) and papillary (PCP) - have been described. They differ in their molecular features, whereby activating mutations in BRAF (V600E) and CTNNB1 genes characterize PCP and ACP, respectively. Recently, both variants have been shown to express elevated PD-L1 protein expression, but ACP also exhibited tumor cell-intrinsic PD-1 expression. In this study we analyze these molecular alterations in 52 cases with a long follow-up and examine their associations with immunohistochemical and clinical characteristics. ACPs comprise 73.1% of cases, while 21.2% are PCPs. Aberrant nuclear immunoreactivity for ß-catenin was observed in all ACPs. BRAF p.V600E mutations were observed in 90.9% of PCPs. Only one ACP case featured both alterations. Both types of CP exhibited strong nuclear staining for p63 with diffuse and basal distribution. ACP and PCP consistently expressed PD-L1, most in a substantial percentage of tumor cells, with a distinctive spatial distribution of expression in each subtype; only ACP demonstrated PD-1 expression. There was no evidence of differences in clinical prognosis between ACPs and PCPs. The identification of hallmark molecular signatures in the two CP variants is useful for sub-categorization in routine histopathology reporting. It is also pertinent to personalized therapy and for the development of improved non-invasive therapeutic strategies in this disease.

MEN1-associated primary hyperparathyroidism in the Spanish Registry: clinical characterictics and surgical outcomes.

Primary hyperparathyroidism is the most frequent manifestation of multiple endocrine neoplasia type 1 (MEN1) syndrome. Bone and renal complications are common. Surgery is the treatment of choice, but the best timing for surgery is controversial and predictors of persistence and recurrence are not well known. Our study describes the clinical characteristics and the surgical outcomes, after surgery and in the long term, of the patients with MEN1 and primary hyperparathyroidism included in the Spanish Registry of Multiple Endocrine Neoplasia, Pheochromocytomas and Paragangliomas (REGMEN). Eighty-nine patients (49 men and 40 women, 34.2 ± 13 years old) were included. Sixty-four out of the 89 underwent surgery: a total parathyroidectomy was done in 13 patients, a subtotal parathyroidectomy in 34 and a less than subtotal parathyroidectomy in 15. Remission rates were higher after a total or a subtotal parathyroidectomy than after a less than subtotal (3/4 and 20/22 vs 7/12, P < 0.05), without significant differences in permanent hypoparathyroidism (1/5, 9/23 and 0/11, N.S.). After a median follow-up of 111 months, 20 of the 41 operated patients with long-term follow-up had persistent or recurrent hyperparathyroidism. We did not find differences in disease-free survival rates between different techniques, patients with or without permanent hypoparathyroidism and patients with different mutated exons, but a second surgery was more frequent after a less than subtotal parathyroidectomy.

No todo son adenopatías / Not everything is an adenopathy

Las tumoraciones cervicales son habituales en niños. Lo más frecuente es que se trate de adenopatías secundarias a infecciones, virales o bacterianas. No obstante, es conveniente tener en cuenta otras causas de adenopatías y la existencia de otros procesos que pueden confundirse con ellas. La exploración mediante ecografía es la técnica de elección para diferenciar la lesión y determinar sus características. Presentamos el caso clínico de una paciente con adenopatías cervicales, a la que se diagnosticó una masa congénita con ecografía en Atención Primaria

Cervical masses are frequent in children. Most often they are lymphadenopathies secondaries to infection, viral or bacterial. However, we should think in other causes of adenopathy and other processes that may be confused with them. Ultrasound examination is the technique of choice to differentiate the lesion and determine its characteristics. We present a patient with cervical adenopathies, who was diagnosed a congenital mass with ultrasound in Primary Care

Análisis de los resultados del tratamiento de la enfermedad de Cushing en los hospitales de Castilla-La Mancha / Assessment of the outcomes of the treatment of Cushing's disease in the hospitals of Castilla-La Mancha

OBJETIVO: El tratamiento de la enfermedad de Cushing plantea interesantes dilemas en la práctica clínica. Nuestro objetivo es analizar los resultados y complicaciones de los distintos tratamientos de esta enfermedad. MATERIAL Y MÉTODOS: Se recopilaron datos mediante revisión de las historias clínicas de 22 pacientes (86,4% mujeres), mayores de 18 años, diagnosticados de enfermedad de Cushing entre los años 2000 y 2012, con seguimiento en el Complejo Hospitalario Universitario de Albacete, Hospital Virgen de la Salud (Toledo), Hospital General de Ciudad Real, Hospital Virgen de la Luz (Cuenca), Hospital Nuestra Señora del Prado (Talavera de la Reina) y en el Complejo Hospitalario la Mancha Centro (Alcázar de San Juan). RESULTADOS: En todos los casos el tratamiento de elección fue el quirúrgico. Se consiguió la curación bioquímica en el 72,7%. Nueve pacientes desarrollaron diabetes insípida en el perioperatorio, de las que 2 resultaron permanentes. Tres pacientes desarrollaron diabetes insípida permanente, que no había sido identificada en el perioperatorio. Aparecieron nuevos déficits hormonales adenohipofisarios posquirúrgicos en 7 pacientes. Diecisiete pacientes recibieron tratamiento médico prequirúrgico con ketoconazol (5 también postoperatorio), consiguiéndose la normalización del cortisol libre urinario en el 70%. Tres pacientes se irradiaron por persistencia de hipersecreción y, tras una mediana de seguimiento de 85,8 meses, se ha conseguido la curación en todos; ninguno de ellos ha desarrollado tumores, alteraciones vasculares ni otra complicación. CONCLUSIONES: Nuestro estudio presenta los resultados del manejo de la enfermedad de Cushing en centros que no son de referencia nacional para esta enfermedad, lo que posiblemente refleja la práctica clínica habitual en esta enfermedad

OBJECTIVE: Treatment of Cushing's disease poses interesting dilemmas in clinical practice. The aim of our study was to analyze the outcomes of the different treatments, the control and recurrence rates, and the complications derived from them. MATERIAL AND METHODS: Data were collected from the clinical records of 22 patients over 18 years of age (86.4% women). They had been diagnosed with Cushing's disease between 2000 and 2012, and were monitored at Complejo Hospitalario Universitario-Albacete, Hospital Virgen de la Salud-Toledo Hospital General Universitario de Ciudad Real, Hospital Virgen de la Luz-Cuenca, Hospital Nuestra Señora del Prado-Talavera de la Reina, and Complejo Hospitalario la Mancha Centro-Alcázar de San Juan. RESULTS: Surgery was the treatment of choice in all patients. Biochemical cure was achieved in 72.2% of patients. Nine patients developed in the early postoperative period diabetes insipidus, which became in 2 patients only. Surprisingly, 3 patients with normal postoperative neurohypophyseal function later developed permanent diabetes insipidus. New hormone deficiencies occurred in 7 patients. Seventeen patients received ketoconazole before surgery (5 of them after surgery also), and 70% of them achieved normal urinary free cortisol levels. Three patients also received radiotherapy, and all of them were cured after a median follow-up of 85.5 months; they developed no tumors or other complications. CONCLUSIONS: Our study reports the outcomes of management of Cushing's disease in non-reference centers for this disease, possibly giving a realistic picture of standard clinical practice for the condition in Spain

Guía de práctica clínica para el diagnóstico y tratamiento de la apoplejía hipofisaria / Clinical practice guideline for the diagnosis and treatment of pituitary apoplexy

La apoplejía hipofisaria (AH) clásica es un síndrome clínico agudo, potencialmente fatal, provocado por la hemorragia y/o infarto de la glándula hipofisaria. Constituye uno de los cuadros clínicos de urgencia neuroendocrinológica. Sin embargo, no existe un consenso claro sobre cuáles pueden ser las mejores opciones para su diagnóstico y tratamiento. OBJETIVO: Elaborar una guía de práctica clínica con una serie de recomendaciones para el diagnóstico y tratamiento de los pacientes con AH basadas en la evidencia médica disponible, que sirva de ayuda a los profesionales implicados en su cuidado. MÉTODOS: Se ha tomado como base la guía clínica de diagnóstico y tratamiento de la apoplejía hipofisaria, publicada en el año 2006 por el Grupo de Trabajo de Neuroendocrinología de la Sociedad Española de Endocrinología y Nutrición (SEEN), así como la Guía Británica de Práctica Clínica publicada en 2011. Se ha trabajado en la adaptación al formato utilizado en la mayoría de las revistas médicas internacionales. Para ello, tras la revisión bibliográfica actualizada, se ha evaluado la calidad de la evidencia y el peso de las recomendaciones de acuerdo con el sistema propuesto por la Agency for Health Care Policy and Research (AHCPR). CONCLUSIONES: El diagnóstico de apoplejía hipofisaria debería valorarse en aquellos pacientes con cefalea aguda grave, con o sin síntomas neurooftalmológicos. Se realizará una evaluación clínica completa. La evaluación analítica urgente incluirá medición de electrólitos, función renal y hepática, hemograma y estudio de coagulación y concentraciones basales de hormonas hipofisarias y periféricas. Será crucial descartar el déficit de hormona adrenocorticotropa (ACTH). Si el estado del paciente lo permite, debe realizarse una campimetría y una resonancia magnética (RM) urgente para confirmar el diagnóstico. En pacientes con inestabilidad hemodinámica, disminución de nivel de conciencia, disminución de la agudeza visual y defectos extensos en el campo visual se recomienda realizar descompresión quirúrgica en la primera semana tras el inicio de los síntomas. Los pacientes con sintomatología más leve pueden ser tratados de forma conservadora, bajo supervisión estrecha. El tratamiento de la AH debería realizarse en un centro donde exista disponibilidad y experiencia en el tratamiento neuroquirúrgico por vía transesfenoidal y posibilidad de seguimiento oftalmológico y endocrinológico

Classic pituitary apoplexy (PA) is an acute, life-threatening clinical syndrome caused by acute hemorrhage and/or infarction of the pituitary gland. PA is considered a neuroendocrinological emergency. However, there is no consensus about the best options for PA diagnosis and management. OBJECTIVE: To develop a clinical practice guideline with a number of recommendations for diagnosis and treatment of patients with PA based on the medical evidence available, in order to help clinicians involved in their care. METHODS: The clinical guideline for diagnosis and treatment of pituitary apoplexy issued in 2006 by the Neuroendocrinology Working Group of the Spanish Society of Endocrinology and Nutrition (SEEN) and the British Clinical Practice Guideline published in 2011 were taken as the basis. The text has been adapted to the format used in most international medical journals. For this, after updated medical literature, the quality of evidence and the strength of the recommendations were evaluated using the system proposed by the Agency for Health Care Policy and Research (AHCPR). CONCLUSIONS: Diagnosis of pituitary apoplexy should be considered in all patients with acute severe headache with or without neuro-ophthalmic signs. Patients with PA must undergo a complete history and physical examination. All patients with suspected pituitary apoplexy should have urgent blood samples drawn to test electrolytes, renal function, liver function, coagulation screen, complete blood count, and basal levels of pituitary and peripheral hormones, and to rule out adrenocorticotropic hormone (ACTH) deficiency. Formal visual field assessment should be performed when the patient is clinically stable. Magnetic resonance imaging (MRI) is the imaging test of choice to confirm diagnosis. Indications for empirical urgent corticosteroid therapy in patients with PA include hemodynamic instability, impaired consciousness, reduced visual acuity, and severe visual field defects. In patients with these severe neuro-ophthalmic signs, surgery should be considered. Surgery should preferably be performed within seven days of the onset of symptoms. Patients with mild and stable signs may be managed conservatively with careful monitoring. Treatment and long-term follow-up of patients with PA should be conducted by a multidisciplinary team consisting, amongst others, of an experienced pituitary neurosurgeon, an ophthalmologist, and an endocrinologist
