El Cateterismo de Senos Petrosos Inferiores (CSSPPII) es una prueba útil para diferenciar entre el origen central y ectópico del síndrome de Cushing hormona adrenocorticotropa (ACTH)-dependiente. Presentamos el protocolo utilizado en nuestro centro y la evaluación de su rendimiento diagnóstico.

Contexto: la enfermedad de Cushing es una enfermedad poco común en la población general, con una evolución clínica insidiosa, lo cual genera un reto para el diagnóstico oportuno a partir de la sospecha clínica. Al tener en cuenta el origen de la enfermedad, dado por la presencia de un tumor hipofisario secretor de la hormona adrenocorticótropa (ACTH); el tratamiento debe estar dirigido a lograr el control bioquímico y la resección de la masa tumoral. El seguimiento del paciente, orientado a vigilar el control de la enfermedad y detectar de forma temprana el desarrollo de comorbilidades, es un aspecto clave en el manejo adecuado de la enfermedad. Objetivo: definir criterios para el diagnóstico, el tratamiento y el seguimiento de la enfermedad de Cushing en pacientes colombianos. Metodología: se realizó un consenso tipo Delphi modificado con un grupo multidisciplinario de expertos en el manejo del paciente con enfermedad de Cushing (médicos endocrinólogos y neurocirujanos), donde la dirección del consenso fue realizada por un médico farmacólogo clínico. Los resultados fueron analizados y discutidos y, a partir de la consecución de consensos, se presenta una serie de recomendaciones en los diferentes apartados de la enfermedad de Cushing. Resultados: se generaron recomendaciones basadas en la opinión de expertos para el abordaje del paciente con enfermedad de Cushing, incluyendo los aspectos de sospecha clínica, diagnóstico bioquímico e imagenológico, tratamiento mediante intervención quirúrgica, alternativas de tratamiento farmacológico, radiocirugía y seguimiento del paciente. Conclusiones: en Colombia, es importante fortalecer el conocimiento médico desde la atención primaria hasta el especialista con alta experticia en temas como el correcto diagnóstico, el manejo y el seguimiento del paciente con enfermedad de Cushing para lograr la detección temprana de la enfermedad y disminuir la progresión de las comorbilidades asociadas.

Contexto: la pasireotida ha demostrado eficacia en el tratamiento de pacientes con enfermedad de Cushing y acromegalia; sin embargo, es frecuente que los pacientes tratados con pasireotida presenten hiperglucemia. Objetivo: proporcionar lineamientos y recomendaciones en Colombia para el control y el manejo de hiperglucemia secundaria a pasireotida en pacientes con enfermedad de Cushing y acromegalia. Metodología: se utilizó la metodología de panel de expertos. Previo al panel se hizo una revisión de la evidencia disponible para las preguntas de interés formuladas por especialistas en Endocrinología, la cual fue actualizada posterior a la reunión. Participaron especialistas de diferentes zonas del país, quienes discutieron las preguntas y formularon recomendaciones para el control y el tratamiento de la hiperglucemia secundaria a pasireotida en enfermedad de Cushing y acromegalia. Resultados: se formularon 16 recomendaciones para el control y manejo de la hiperglucemia secundaria al uso de pasireotida en pacientes con enfermedad de Cushing y 7 para pacientes con acromegalia. Las recomendaciones fueron formuladas y validadas por un panel de expertos, a partir de evidencia y de su experiencia clínica. Conclusiones: es frecuente que pacientes con acromegalia o enfermedad de Cushing tratados con pasireotida presenten alteraciones en el metabolismo de la glucosa como consecuencia de la terapia. Existe poca evidencia de alto nivel para la formulación de recomendaciones para el manejo de la hiperglucemia secundaria al uso de pasireotida en ambas patologías, aquí las recomendaciones generadas fueron con base en opinión de expertos y son las primeras publicadas para Colombia.

Pituitary tumors (PT) account for 15% of intracranial tumors affect 10.7-14.4% of the population although the incidence of clinically relevant PT is 5.1 cases/100,000 inhabitants. Surgical treatment is indicated in PTs with hormone hypersecretion (except for prolactin-producing PTs) and those with local compressive or global neurological symptoms. Multidisciplinary care, is essential for patients with PTs, preferably delivered in a center of excellence and based on a well-defined care protocol. In order to facilitate and standardize the clinical procedures for this type of tumor, this document gathers the positioning of the Neuroendocrinology Knowledge Area of the Spanish Society of Endocrinology and Nutrition (SEEN) and the Spanish Society of Neurosurgery (SENEC) on the management of patients with PTs and their preoperative, surgical and postoperative follow-up., (Copyright © 2023 Sociedad Española de Neurocirugía.

Objective: Our aim was to characterise a cohort of patients with Cushing's disease (CD) who did not present pituitary adenoma in magnetic resonance imaging (MRI), needing a catheterisation of the inferior petrosal sinus (CIPS), and to study the pathological findings of the pituitary gland in these subjects after transsphenoidal surgery in order to establish the aetiology of CD. Furthermore, we evaluated possible differences in the features of the diagnosis between hyperplasia and adenoma., Subjects and Methods: We included 16 subjects. 17 CIPS were done. Hormonal parameters were measured using standard methods. A microscopic histochemical study following standard procedures and immunohistochemical analysis was performed. The diagnostic criteria for adenoma and hyperplasia were based on the WHO classification., Results: One patient was excluded for presenting an ACTH-producing bronchial neuroendocrine tumour. The 15 subjects with CD have a positive CIPS test indicating hypophyseal ACTH production. After transsphenoidal surgery, 12 patients showed a microadenoma and three (20%) a corticotroph cell hyperplasia. We found four recurrences after the transsphenoidal surgery (26%), with a mean time for recurrence of 105 months. We found that recurrence was more frequent in subjects with hyperplasia, and in those subjects with lower right/left ACTH ratio., Conclusion: Our study, which was focused on patients with CD with no pituitary adenoma detected by MRI and a positive CRH test after CIPS, has found that 20% showed corticotroph cell hyperplasia as the cause of CD. Right/left ACTH ratio after CIPS was useful to differentiate adenoma from hyperplasia. This finding may have important prognostic and treatment implications. More studies are necessary to confirm our result., (Copyright © 2022 SEEN and SED. Published by Elsevier España, S.L.U. All rights reserved.)

Purpose: Identify presurgical factors associated with surgical remission in Cushing's disease (CD)., Methods: All the patients with ACTH-dependent Cushing's Syndrome in follow-up at our centre between 2014-2021 (n=40) were identified. Those patients with CD diagnosis who underwent transsphenoidal surgery by the same neurosurgeon (n=32) were included. Surgical remission was defined as plasma cortisol <1.8μg/dl and normal or low urinary free cortisol (UFC) after surgery., Results: Sixty-three per cent (n=20) were women, and the mean age at diagnosis was 42.3±17.9 years. Six patients had macroadenomas, 17 had microadenomas, and in the other 9 patients, no pituitary lesion was identified on the MRI. Seven patients were previously operated on in another centre. Surgical remission was achieved in 75% (n=24). Only three patients experienced recurrence. No association between pre-surgical demographic (age, sex, comorbidities) or hormonal (UFC, ACTH, late-night salivary cortisol levels) characteristics and the probability of surgical remission was observed. The only variable associated with a greater chance of remission was the presurgical visualisation of the adenoma on MRI (OR 8.3, P=0.02). It was also observed that patients with a history of a previous pituitary surgery had a lower tendency to achieve remission, although statistical significance was not reached (OR 0.17, P=0.09)., Conclusions: In our experience, 75% of patients with CD achieved biochemical cure after the intervention. Surgical remission was up to eight times more frequent in those patients in whom the adenoma was visualised before the intervention, but no other presurgical predictive factors of cure were identified., (Copyright © 2021 SEEN and SED.
