Gastrointestinal manifestations of systemic sclerosis: current approaches and emerging therapies

Abstract

Purpose of review – This review highlights recent advances in the understanding and management of gastrointestinal manifestations in systemic sclerosis (SSc). It is intended for clinicians and researchers aiming to improve diagnostic accuracy and therapeutic strategies in managing SSc-related gastrointestinal disease.Recent findings – Gastrointestinal involvement in SSc is highly variable in terms of clinical presentation, symptom severity, progression, timing of onset, and response to treatment. Emerging research highlights early immune-mediated damage to neural and muscular gastrointestinal tissues, microbiome alterations, and vascular dysfunction – particularly in patients with late-onset gastrointestinal disease – as key factors guiding the development of personalized, precision-based approaches for well defined patient subgroups. Recent studies underscore the value of early, objective assessment of gastrointestinal motility using tools like whole-gut transit scintigraphy and abdominal vascular ultrasound. New treatment strategies are also being explored for severe manifestations, including investigating mechanisms behind acid-suppressive therapy-resistant gastroesophageal reflux disease and implementing adjunctive therapies for gastrointestinal dysmotility.Summary – Gastrointestinal involvement in SSc poses a complex clinical challenge, particularly in patients with severe dysmotility and symptoms refractory to standard management strategies. This review offers timely, evidence-based insights to support clinicians in delivering more personalized and effective patient care and highlights critical gaps to address in future research.
