Coeliac disease in childhood: An overview

Area of Science:

• Immunology
• Gastroenterology
• Genetics

Background:

• Coeliac disease (CD) is an autoimmune disorder affecting approximately 1% of the global population, triggered by gluten ingestion in genetically predisposed individuals.
• Once considered a rare enteropathy, CD is now recognized as a common multisystem disorder with diverse clinical manifestations across all age groups.
• Contemporary understanding highlights a shift from classical symptoms like diarrhea and malnutrition to milder gastrointestinal issues, extra-intestinal symptoms, or asymptomatic presentations, particularly in screened populations.

Purpose of the Study:

• To underscore the importance of recognizing the varied clinical presentations of coeliac disease.
• To emphasize the need for a high index of suspicion for timely diagnosis and intervention.
• To review current diagnostic approaches, including emerging biopsy-free diagnostic criteria.

Main Methods:

• Review of current literature and clinical guidelines regarding coeliac disease diagnosis and management.
• Analysis of evolving understanding of CD pathogenesis and clinical spectrum.
• Discussion of advancements in diagnostic techniques and therapeutic strategies.

Main Results:

• Coeliac disease presents with a wide spectrum of symptoms, often deviating from classical presentations, necessitating increased clinical awareness.
• Recent guidelines permit biopsy-free diagnosis in specific symptomatic pediatric cases, simplifying the diagnostic pathway.
• A strict, lifelong gluten-free diet remains the cornerstone of management, with novel treatments in development.

Conclusions:

• Early recognition of diverse CD manifestations is crucial for prompt diagnosis and management.
• Diagnostic criteria are evolving, allowing for non-invasive diagnosis in select cases.
• While a gluten-free diet is the current standard, research into new therapeutic agents is ongoing.
