GI Manifestations With a Focus on the Esophagus: Recent Progress in Understanding Pathogenesis

Area of Science:

• Gastroenterology
• Rheumatology
• Immunology

Background:

• Esophageal dysfunction is a frequent complication in systemic sclerosis (SSc).
• Current treatment options for scleroderma esophageal disease are limited.
• Heterogeneous clinical presentation complicates diagnosis and management.

Purpose of the Study:

• To review recent updates in the diagnosis, treatment, and characterization of scleroderma esophageal disease.
• To highlight novel diagnostic tools and therapeutic strategies for SSc-related esophageal issues.
• To discuss molecular insights and animal models for better understanding the disease.

Main Methods:

• Review of recent literature on SSc esophageal dysfunction.
• Analysis of novel diagnostic tools and emerging therapeutic agents.
• Exploration of molecular stratification and animal models (e.g., Fli1 knockout mouse).

Main Results:

• Novel diagnostic tools offer better insight into esophageal dysmotility in SSc.
• New drugs are under investigation to improve symptoms and quality of life.
• Molecular signatures in SSc esophagus identified, and an animal model with esophageal phenotype developed.
• Clinical presentation remains heterogeneous, posing diagnostic and management challenges.

Conclusions:

• Improved diagnostic tools and molecular approaches are crucial for better characterization of SSc esophageal disease.
• Further research into novel treatments and understanding molecular mechanisms is needed.
• Enhanced characterization will aid in improving management and treatment decisions for patients.
