Telotristat Etiprate in a Subset of Carcinoid Syndrome Patients Who Have High Levels of Urinary 5-hydroxyindoleacetic Acid and Frequent Flushing Abstract #1068

Introduction: Serotonin is a key mediator of carcinoid syndrome (CS). CS patients (pts) with high levels of urinary 5-hydroxyindoleacetic acid (u5-HIAA, a serotonin metabolite) and >3 flushing episodes/day are at increased risk of developing carcinoid heart disease (CaHD).
Aim(s): Telotristat etiprate (TE) is an oral inhibitor of serotonin synthesis in Phase 3 development for the treatment of CS. There is limited information on the potential benefits of serotonin reduction in CS pts who may be at higher risk for CaHD.
Materials and methods: We retrospectively reviewed data on all pts who received TE in a Phase 2 trial for CS. In pts with elevated baseline u5-HIAA and >3 flushing episodes/day, we assessed reductions in u5-HIAA, bowel movements (BMs) and flushing frequency while on TE.

#2703 Carcinoid Heart Disease: A Retrospective Study and a Multidisciplinary Proposal of a New Algorithm
Introduction: Development of carcinoid heart disease (CHD) is the major negative prognostic factor in patients with the carcinoid syndrome. The only effective treatment is valve replacement. However, the selection of candidates and determination of optimal timing remain unclear. Considerable variability in local treatment strategies exist

#2833 Surgical Correction of Carcinoid Heart Disease Improves Liver Function and 5-Hydroxyindoleacetic Acid Levels
Introduction: Neuroendocrine tumours of the gastrointestinal tract cause carcinoid syndrome and carcinoid heart disease. These tumours secrete serotonin, which can bind to heart valves and cause fibrosis and valve incompetence. Most cases involve the tricuspid valve +/- pulmonary valve. Medical management comprises diuretics for fluid overload and somatostatin analogues to reduce circulating serotonin. Definitive treatment is heart-valve replacement surgery which improves exercise tolerance but has high perioperative mortality. We have previously reported that valve-replacement surgery can reduce 5-hydroxyindoleacetic acid (5-HIAA) levels, reflecting a decline in hormone activity.

#2944 Soluble ST2 (sST2) Levels in the Management of Carcinoid Heart Disease in Patients with Neuroendocrine Cancer
Introduction: The identification of a sensitive biomarker to detect the presence and severity of carcinoid heart disease could allow more selective use of clinical and echocardiographic screening. ST2 is a protein belonging to the family of interleukin 1 receptors, present both in the isoform of transmembrane (ST2L) and in the soluble one (sST2). sST2 blocks the anti-inflammatory, anti-hypertrophic, and anti-fibrotic effects of cytokine IL-33 on the myocardium and recent studies have shown that sST2 levels increase in the blood of patients diagnosed with heart failure.

Introduction: Carcinoid heart disease (CHD) is a poor prognostic factor in neuroendocrine tumours (NETs). However, the extreme variability of diagnostic and treatment approaches reported in literature account for uncertainties on the best management in this selected population.
