Patient journeys are instruments developed by EURORDIS, The Voice of Rare Disease Patients in Europe, to collect patients' experiences; they may identify gaps and areas deserving improvement, as well as elements positively considered by affected persons. As with other patient-reported experiences, they can complete the clinical evaluation and management of a specific disease, improving the often long diagnostic delay, therapy, patient education and access to knowledgeable multidisciplinary teams. This review discusses the utility of such patient-reported experience measures and summarises the experiences of patients with acromegaly, Addison's disease and congenital adrenal hyperplasia from different European countries.

Endogenous/exogenous Cushing's syndrome is characterized by a cluster of systemic manifestations of hypercortisolism, which cause increased cardiovascular risk. Its biological basis is glucocorticoid excess, acting on various pathogenic processes inducing cardiovascular damage. Hypertension is a common feature in Cushing's syndrome and may persist after normalizing hormone excess and discontinuing steroid therapy.

Endocrinology Dept, Germans Trias i Pujol Hospital & Research Institute, Universitat Internacional de Catalunya (UIC), CIBERER, Unit 747, ISCIII, 08916, Badalona, Spain.

This brief review is devoted mainly to publications in the last 5 years dealing with health-related quality of life (QoL) after a diagnosis of endogenous hypercortisolism, due to pituitary-dependent Cushing's disease (CD) or any other cause of Cushing syndrome (CS). Despite improvement after treatment, persistent physical morbidity, neurocognitive problems like worse executive capacity and memory as well as stress intolerance, depressive symptoms and more anxiety, lead to long-term impairment of QoL.

Predicting which acromegaly patients could benefit from somatostatin receptor ligands (SRL) is a must for personalized medicine. Although many biomarkers linked to SRL response have been identified, there is no consensus criterion on how to assign this pharmacologic treatment according to biomarker levels. Our aim is to provide better predictive tools for an accurate acromegaly patient stratification regarding the ability to respond to SRL.

Prostate cancer (PCa) is the most commonly diagnosed malignant neoplasm in men in the Western world. Localized low-risk PCa has an excellent prognosis thanks to effective local treatments; however, despite the incorporation of new therapeutic strategies, metastatic PCa remains incurable mainly due to disease heterogeneity and the development of resistance to therapy. The mechanisms underlying PCa progression and therapy resistance are multiple and include metabolic reprogramming, especially in relation to lipid metabolism, as well as epigenetic remodelling, both of which enable cancer cells to adapt to dynamic changes in the tumour.

Molecular profiling for acromegaly treatment: a validation study.

Endocr Relat Cancer

June 2020

Biomedical Research Networking Center in Rare Diseases (CIBERER), Institute of Health Carlos III (ISCIII), Madrid, Spain.

Article Synopsis
  • Current treatment for acromegaly relies on somatostatin receptor ligands (SRL), but around 50% of patients do not adequately respond to this first-line therapy.
  • Researchers studied tissue from 100 acromegalic patients to identify molecular markers that could predict the response to SRL, finding significant associations with SSTR2, Ki-67, and E-cadherin.
  • E-cadherin emerged as the most reliable predictor of SRL response, suggesting that it could guide treatment decisions after surgery in cases of treatment failure.
