Aim: To evaluate frequency of heart failure syndrome in patients with endogenous hypercortisolism and to establish relationship between effective treatment for hypercortisolism and regression of heart failure with particular emphasis on the observation of NT-proBNP and ST2 levels., Materials and Methods: 56 patients with endogenous hypercortisolism (45 female, mean age 47 years [36; 55] hospitalized with endogenous hypercortisolism to National Medical Research Center for Endocrinology were enrolled in the study. All patients underwent comprehensive clinical investigation including expert echocardiography with speckle tracking and evaluation of NT-proBNP and ST2 cardiac biomarkers at baseline and 6 months after surgical treatment., Results: According to clinical data and elevated biomarkers of cardiac stress 28 out of 56 patients (50%) at baseline met the criteria for heart failure. 20 patients were included in the final analysis. Follow-up investigation with focus on changes in NT-proBNP and ST2 levels demonstrated that surgical correction of endogenous hypercortisolism resulted in resolution of heart failure syndrome in 11 patients (55%)., Conclusion: These preliminary data suggest that signs and symptoms of heart failure are observed in patients with endogenous hypercortisolism in about half the cases. Surgical correction results in resolution of heart failure in approximately two thirds of the cases. Prospective evaluation NT-proBNP and ST2 levels may provide important diagnostic and prognostic information in patients with endogenous hypercortisolism.

Objective: To evaluate diagnostic accuracy of the corticotropin-releasing hormone (CRH) stimulation test and the overnight 8 mg dexamethasone suppression test (DST) for the differentiation of Cushing's disease (CD) and ectopic Cushing's syndrome (ECS)., Methods: Retrospective study in 6 European centers. Inclusion criteria: patients with a) overt adrenocorticotropin (ACTH)-dependent Cushing's syndrome at the time of dynamic testing, b) histopathological confirmed tumors and/or c) postoperative biochemical remission and/or adrenal insufficiency. Optimal cut-offs were calculated via receiver operating characteristic (ROC) analysis using CD as reference., Results: 469 patients were analyzed [78% females; median age 43 years (IQR 19)]. CRH test and overnight 8 mg DST were performed in 420 [CD, n=394 (94%); ECS, n=26 (6%)] and 237 patients [228 CD (96%), 9 ECS (4%)]. Both tests were performed in 205 patients (44%). The post-CRH %-increase at 30 minutes of both ACTH (cut-off ≥31%, sensitivity 83%, specificity 85%, AUC 0.81) and cortisol (cut-off ≥12%, sensitivity 82%, specificity 89%, AUC 0.86) discriminated best between CD and ECS. A test duration of >60 minutes did not improve diagnostic performance of the CRH test. The optimal cortisol cut-off for the %-suppression during the 8 mg DST was ≥55% (sensitivity 80%, specificity 78%, AUC 0.75)., Conclusion: The CRH test has equivalent sensitivity but higher specificity than the 8 mg DST and is therefore the test of first choice. The diagnostic outcome of ACTH and cortisol is well comparable, however, sampling beyond 60 minutes post-CRH does not provide diagnostic benefits., 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 © 2022 Detomas, Ritzel, Nasi-Kordhishti, Wolfsberger, Quinkler, Losa, Tröger, Kroiss, Fassnacht, Vila, Honegger, Reincke and Deutschbein.)

Background: Patients with Cushing syndrome (CS) are at increased risk of venous thromboembolism (VTE). Objective: The aim was to evaluate the current management of new cases of CS with a focus on VTE and thromboprophylaxis. Design and methods: A survey was conducted within those that report in the electronic reporting tool (e-REC) of the European Registries for Rare Endocrine Conditions (EuRRECa) and the involved main thematic groups (MTG’s) of the European Reference Networks for Rare Endocrine Disorders (Endo-ERN) on new patients with CS from January 2021 to July 2022. Results: Of 222 patients (mean age 44 years, 165 females), 141 patients had Cushing disease (64%), 69 adrenal CS (31%), and 12 patients with ectopic CS (5.4%). The mean follow-up period post-CS diagnosis was 15 months (range 3–30). Cortisol-lowering medications were initiated in 38% of patients. One hundred fifty-four patients (69%) received thromboprophylaxis (including patients on chronic anticoagulant treatment), of which low-molecular-weight heparins were used in 96% of cases. VTE was reported in six patients (2.7%), of which one was fatal: two long before CS diagnosis, two between diagnosis and surgery, and two postoperatively. Three patients were using thromboprophylaxis at time of the VTE diagnosis. The incidence rate of VTE in patients after Cushing syndrome diagnosis in our study cohort was 14.6 (95% CI 5.5; 38.6) per 1000 person-years. Conclusion: Thirty percent of patients with CS did not receive preoperative thromboprophylaxis during their active disease stage, and half of the VTE cases even occurred during this stage despite thromboprophylaxis. Prospective trials to establish the optimal thromboprophylaxis strategy in CS patients are highly needed. Significance statement The incidence rate of venous thromboembolism in our study cohort was 14.6 (95% CI 5.5; 38.6) per 1000 person-years. Notably, this survey showed that there is great heterogeneity regarding time of initiation and duration of thromboprophylaxis in expert centers throughout Europe.

Introducción: el carcinoma suprarrenal primario es un tumor poco frecuente, altamente agresivo, de crecimiento rápido, con mayor incidencia entre los 40 y 60 años de edad. Los carcinomas funcionantes representan hasta un 79 % de los tumores corticales, más frecuentes en el sexo femenino, y de estos el 50 % se manifiestan clínicamente como un síndrome de Cushing. La extensión del tumor a estructuras vecinas es común y empeora el pronóstico. La supervivencia media es de 2 años desde el diagnóstico, en particular, cuando existen metástasis en hígado y pulmón. Objetivo: describir las características clínicas, los procederes diagnósticos y terapéuticos de una paciente con carcinoma adrenal de rápida evolución. Presentación del caso: paciente LRS, femenina, blanca, de 49 años de edad, con antecedentes de hipertensión arterial y diabetes mellitus tipo 2, que asiste a consulta por descontrol metabólico y de la hipertensión arterial. Al examen físico, se constatan signos sugestivos de hipercortisolismo, sintomatología que a los 2 meses se acentuó notablemente. Se realizaron estudios basales, dinámicos, imagenológicos y anatomopatológicos, que corroboraron el diagnóstico presuntivo. Se realiza adrenalectomía izquierda con adenectomía regional, y se confirma por anatomía patológica el diagnóstico de carcinoma suprarrenal izquierdo. A los pocos meses de la intervención la paciente fallece con metástasis óseas en columna vertebral. Conclusiones: el reconocimiento temprano de los síntomas y signos de hiperfunción adrenal es muy importante para el diagnóstico y tratamiento oportuno del carcinoma adrenal.
