RESUMEN
Primary aldosteronism (PA) is the most common cause of secondary arterial hypertension. For unilateral cases, surgery offers the possibility of cure, with unilateral adrenalectomy being the treatment of choice, whereas bilateral forms of PA are treated mainly with mineralocorticoid receptor antagonists (MRA). The goals of treatment for PA due to either unilateral or bilateral adrenal disease include reversal of the adverse cardiovascular effects of hyperaldosteronism, normalization of serum potassium in patients with hypokalemia, and normalization of blood pressure. The Primary Aldosteronism Surgery Outcome group (PASO) published a study defining clinical and biochemical outcomes based on blood pressure and correction of hypokalemia and aldosterone to renin ratio (ARR) levels for patients undergoing total unilateral adrenalectomy for unilateral PA. In this review, we provide several practical recommendations for the medical and surgical management and follow-up of patients with PA. (AU)
El hiperaldosteronismo primario (HAP) es la causa más frecuente de hipertensión arterial secundaria. Para los casos unilaterales, la cirugía ofrece la posibilidad de curación, siendo la adrenalectomía unilateral el tratamiento de elección, mientras que las formas bilaterales de HAP se tratan principalmente con antagonistas del receptor de mineralocorticoides (ARM). Los objetivos del tratamiento del HAP debido a enfermedad suprarrenal unilateral o bilateral incluyen la reversión de los efectos cardiovasculares adversos del hiperaldosteronismo, la normalización del potasio sérico en pacientes con hipopotasemia y la normalización de la presión arterial. El grupo Primary Aldosteronism Surgery Outcome (PASO) publicó un estudio que define los resultados clínicos y bioquímicos en función de la presión arterial y la corrección de la hipopotasemia y los niveles del cociente aldosterona/renina (ARR) para pacientes sometidos a adrenalectomía unilateral total por HAP unilateral. En esta revisión ofrecemos varias recomendaciones prácticas para el manejo y el seguimiento médico-quirúrgico de los pacientes con HAP. (AU)

PURPOSE: To describe our current protocol for surgical and postsurgical management of abdominal paragangliomas (PGLs) and pheochromocytomas, with a special focus on multidisciplinary management in centres with experience. METHODS: The physicians involved in the management of patients with abdominal PGLs and pheochromocytomas of our hospital reviewed systematically current knowledge on the surgical management of abdominal PGLs and pheochromocytomas. RESULTS: Currently, surgery is considered the treatment of choice for abdominal PGLs and pheochromocytomas. The choice of surgical approach is determined based on the location of the lesion, size, patientÌs body habitus and the likelihood of malignancy. Laparoscopic surgery is usually considered the gold standard approach for pheochromocytomas, but open access should be considered in invasive and/or potentially malignant tumours >8-10â¯cm and for abdominal PGLs. Postsurgical management of pheochromocytomas and PGLs includes close hemodynamic monitoring and treatment of postsurgical complications, the pathological study of the surgical specimen, reassessment of hormonal and/or radiological status and planning of follow-up based on the risk of recurrence and malignancy. CONCLUSION: Surgery represents the treatment of choice of most abdominal PGLs and pheochromocytomas. Optimal postsurgical evaluation, including hemodynamic, pathological, hormonal, and radiological evaluation, should be performed by a multidisciplinary team specializing in PGL/pheochromocytoma management.

PURPOSE: To evaluate the prevalence, risk factors and evolution of diabetes mellitus (DM) after targeted treatment in patients with primary aldosteronism (PA). METHODS: A retrospective multicenter study of PA patients in follow-up at 27 Spanish tertiary hospitals (SPAIN-ALDO Register). RESULTS: Overall, 646 patients with PA were included. At diagnosis, 21.2% (n = 137) had DM and 67% of them had HbA1c levels < 7%. In multivariate analysis, family history of DM (OR 4.00 [1.68-9.53]), the coexistence of dyslipidemia (OR 3.57 [1.51-8.43]) and advanced age (OR 1.04 per year of increase [1.00-1.09]) were identified as independent predictive factors of DM. Diabetic patients were on beta blockers (46.7% (n = 64) vs. 27.5% (n = 140), P < 0.001) and diuretics (51.1% (n = 70) vs. 33.2% (n = 169), p < 0.001) more frequently than non-diabetics. After a median follow-up of 22 months [IQR 7.5-63.0], 6.9% of patients developed DM, with no difference between those undergoing adrenalectomy and those treated medically (HR 1.07 [0.49-2.36], p = 0.866). There was also no significant difference in the evolution of glycemic control between DM patients who underwent surgery and those medically treated (p > 0.05). CONCLUSION: DM affects about one quarter of patients with PA and the risk factors for its development are common to those of the general population. Medical and surgical treatment provides similar benefit in glycemic control in patients with PA and DM.

Objetivo Describir nuestro protocolo actual para el manejo quirúrgico y posquirúrgico de los paragangliomas abdominales (PGL) y los feocromocitomas, con especial atención en el manejo multidisciplinar en centros con experiencia. Métodos Los facultativos implicados en el tratamiento de pacientes con PGL abdominales y feocromocitomas de nuestro hospital revisaron sistemáticamente la evidencia científica actualmente disponible sobre el tratamiento quirúrgico de los PGL abdominales y feocromocitomas. Resultados La cirugía se considera el tratamiento de primera elección para los PGL abdominales y feocromocitomas. La decisión sobre el tipo de abordaje quirúrgico se basa en la localización y el tamaño de la lesión, la constitución corporal del paciente y la probabilidad estimada de malignidad. La cirugía laparoscópica suele considerarse el abordaje de referencia para los feocromocitomas, pero en los tumores invasivos y/o potencialmente malignos de más de 8-10 cm y en los PGL abdominales debe considerarse el abordaje abierto. El tratamiento posquirúrgico de los feocromocitomas y los PGL incluye una monitorización hemodinámica estrecha, el tratamiento de las complicaciones posoperatorias, el estudio patológico de la muestra quirúrgica, la reevaluación del estado hormonal y/o radiológico y la planificación del seguimiento en función del riesgo de recurrencia y malignidad. Conclusión La cirugía representa el tratamiento de elección de la mayoría de los PGL abdominales y feocromocitomas. La evaluación posoperatoria óptima, que incluye la evaluación hemodinámica, patológica, hormonal y radiológica, debe ser realizada por un equipo multidisciplinar especializado en el tratamiento de PGL/feocromocitomas (AU)

Objetivo Se evaluó la prevalencia de hiperplasia suprarrenal macronodular bilateral primaria (PBMAH). También se analizó el fenotipo diferencial de los pacientes con PBMAH en comparación con otras lesiones suprarrenales bilaterales que no cumplían con la definición de PBMAH. Métodos Revisamos las historias clínicas de 732 pacientes diagnosticados de incidentaloma suprarrenal en nuestro centro. Se incluyeron 98 pacientes con hipercortisolismo subclínico para el análisis. Se definió PBMAH como la presencia de cortisol plasmático > 1,8 μg/dL después de una prueba de 1 mg de dexametasona durante la noche, hiperplasia suprarrenal bilateral y nódulos suprarrenales bilaterales > 1 cm. Resultados Un total de 31 pacientes tenían PBMAH. Los pacientes con PBMAH mostraron una mayor prevalencia de secreción autónoma de cortisol (cortisol plasmático > 5,0 μg/dL después de la prueba de 1 mg de dexametasona durante la noche) que los pacientes sin PBMAH (OR 4,1, IC del 95%: 1,38-12,09, p = 0,010). El tamaño del tumor y la masa adenomatosa total fueron significativamente mayores en pacientes con PBMAH en comparación con los pacientes sin PBMAH (30,2 ± 12,16 vs. 24,3 ± 8,47 mm, p = 0,010 y 53,9 ± 20,8 vs. 43,3 ± 14,62 mm, p = 0,023), respectivamente. Una mayor proporción de pacientes con PBMAH tenían diabetes en comparación con los pacientes sin PBMAH (45,2% vs. 25,4%, p = 0,05). Conclusión PBMAH está presente en un tercio de los pacientes con incidentaloma suprarrenal e hipercortisolismo subclínico. Los pacientes con PBMAH mostraron una mayor secreción autónoma de cortisol, mayor tamaño del tumor y diabetes que aquellos sin PBMAH (AU)
Aim This study evaluated prevalence of primary bilateral macronodular adrenal hyperplasia (PBMAH). It also analyzed the differential phenotype of patients with PBMAH compared to other bilateral adrenal lesions that do not meet the definition of PBMAH. Methods We reviewed the medical records of 732 patients diagnosed with an adrenal incidentaloma at our center. Ninety-eight patients with subclinical hypercortisolism were included in the analysis. We defined PBMAH as the presence of plasma cortisol > 1.8 μg/dL after an over-night 1-mg dexamethasone test, bilateral adrenal hyperplasia, and bilateral adrenal nodules > 1 cm. Results A total of 31 patients had PBMAH. Patients with PBMAH showed greater prevalence of autonomous cortisol secretion (plasma cortisol > 5.0 μg/dL after an overnight 1-mg dexamethasone test) than patients without PBMAH (OR 4.1, 95%CI 1.38-12.09, p = 0.010). Tumor size and total adenomatous mass were significantly greater in patients with PBMAH compared to patients without PBMAH (30.2 ± 12.16 vs. 24.3 ± 8.47 mm, p = 0.010 and 53.9 ± 20.8 vs. 43.3 ± 14.62 mm, p = 0.023), respectively. A greater proportion of patients with PBMAH had diabetes compared to patients without PBMAH (45.2% vs. 25.4%, p = 0.05). Conclusion PBMAH is present in one-third of patients with adrenal incidentaloma and subclinical hypercortisolism. Patients with PBMAH showed greater autonomous cortisol secretion, bigger tumor size, and higher rates of diabetes than those without PBMAH (AU)

OBJECTIVE: To offer a practical guide for the presurgical and anesthetic management of pheochromocytomas and sympathetic paragangliomas (PGLs). METHODS: This protocol was based on a comprehensive review of the literature and on our own multidisciplinary team's experience from managing pheochromocytoma and sympathetic PGLs at a referral center. RESULTS: Patients with pheochromocytomas and sympathetic paragangliomas (PGLs) may develop potentially life-threatening complications, especially during surgical procedures. A complete biochemical, radiological, genetic, and cardiological assessment is recommended in the preoperative stage as it provides an evaluation of the risk of surgical complications and malignancy, allowing individualization of the presurgical treatment. Treatment with α-blockade and proper volume expansion in the preoperative stage significantly reduces the perioperative morbidity. During surgery, the anesthesiologist should look for a deep anesthetic level that inhibits the cardiovascular effects of catecholamines to minimize the risk of intraoperative complications. CONCLUSIONS: An optimal presurgical evaluation of pheochromocytomas/ sympathetic PGL requires a multidisciplinary approach, including a complete hormonal, radiological, cardiac, genetic, and functioning evaluation in most cases. A proper preoperative evaluation in combination with strict blood pressure and heart rate control, and blood volume status optimization, will significantly reduce the risk of intraoperative and perioperative complications. In those patients who unfortunately develop intraoperative complications, the role of the anesthesiologist is essential since the selection of the appropriate management has a direct impact on morbimortality reduction.

PURPOSE: To identify presurgical clinical, hormonal and radiological variables associated with surgical remission in acromegaly and develop a predictive model for surgical remission. METHODS: Ambispective study of acromegaly surgical patients followed in two Spanish tertiary hospitals. Patients operated by the same neurosurgeon by endonasal endoscopic transsphenoidal approach (n = 49) were included to develop the predictive model, and patients operated by other neurosurgeons (n = 37) were used for external validation of the predictive model. The predictive model was developed with a multivariate logistic regression model based on the 2000 criteria. RESULTS: 86 acromegalic patients were included. 49 patients, 83.7% with macroadenomas and 32.7% with Knosp grade > 2, were included for the development of the predictive model. The overall rate of surgical remission with the 2000 criteria was 73.5% and 51.0% with the 2010 criteria. Using the 2000 criteria, variables associated with surgical remission were: older age (OR = 1.1, p = 0.001), lower basal presurgical GH levels (OR = 0.9, p = 0.003), Knosp 0-2 (OR = 34.1, p < 0.0001) and lower maximum pituitary adenoma diameter (OR = 0.9, p = 0.019). The model with the best diagnostic accuracy to predict surgical remission combined age, Knosp 0-2 and presurgical GH levels (AIC = 29.7, AUC = 0.95) with a sensitivity of 93.8% and a specificity of 75.0%. The estimated loss of prediction with the external validation (n = 37) was 4.2%. CONCLUSION: The predictive model with the best diagnosis accuracy for surgical remission combined age, Knosp 0-2 and presurgical GH levels, with a sensitivity of 93.8% and a specificity of 75.0%. This model could be very useful to select candidates to preoperative medical treatment and planning the follow-up.

There is a lack of evidence on timing, frequency, and duration of postoperative endocrine, radiologic, and ophthalmologic assessments that should be performed after pituitary surgery (PS). However, it is known that careful optimization of treatment and follow-up strategies as well as a multidisciplinary approach may have a significant impact on long-term outcomes, improving surgical results, minimize complications and facilitate their correct treatment if occurring, and optimize the hormonal, ophthalmological, and radiological reassessment throughout the follow-up. Considering that there are no specific guidelines on the postoperative management of patients with pituitary tumors (PT), we present our protocol for the postoperative management of patients with PT. It has been elaborated by the multidisciplinary team of a Spanish Pituitary Tumor Center of Excellence (PTCE) that includes at least one neurosurgeon, ENT, neuroradiologist, neuro-ophthalmologist, endocrine pathologist and endocrinologist specialized in pituitary diseases. We elaborated this guideline with the aim of sharing our experience with other centers involved in the management of PT thereby facilitating the postoperative management of patients submitted to PS.
