Introduction: Anti-cytokine therapy may be useful for the treatment of active thyroid associated ophthalmopathy (TAO). We aimed to establish the effects of selected cytokines on intercellular adhesion molecule 1 (ICAM1) expression and adipogenesis in orbital fibroblasts (OFs) from patients with and without TAO.Methods: Orbital tissue was taken during surgery from 5 patients with TAO and 5 control subjects. Primary cultures of OFs were established and sta...

Lost to follow-up (LTFU) is a frequent problem in chronic diseases not evaluated yet in acromegaly despite the long-term need of medical treatment and complications survey in this disease.Objectives: Evaluation of the prevalence of LTFU patients in a multi-center cohort, characteristics of defaulters and description of their evolution after they have been searched and found.Méthods: Observational multicentric (25 centers study...

Background: Fibroblast growth factor 23 (FGF23) is a key protein in bone homeostasis regulatingserumphosphateand calcitriol (1,25(OH)2D3) concentrations. Analytical performance and reference ranges of FGF23 assays differ by molecule assayed (intact or C-terminal FGF23) and manufacturer. We aim to establish reference interval values for both cFGF23 and iFGF23 in a paediatric population.Methods: Writt...

Background: Mitotane antitumor efficacy is related to plasma levels. Objective responses have been associated with mitotane plasma levels >14 mg/l. However, high plasma levels >20 or >30 mg/l are at higher risk of toxicity, especially neurotoxicity. National-based survey is lacking to evaluate the frequency and severity of high mitotane plasma levels. Our aim was to retrospectively describe serious adverse events (SAE).Methods: Mitotane plasm...
