Diagnosis and Treatment Patterns in Celiac Disease

Area of Science:

• Gastroenterology
• Immunology
• Public Health

Background:

• Celiac disease (CD) is an immune-mediated disorder triggered by gluten, with evolving non-gastrointestinal presentations like anemia and osteoporosis.
• Global prevalence of CD is increasing due to enhanced screening and diagnostics, yet significant variations exist in care practices.
• The study addresses the current landscape of CD diagnosis and treatment patterns worldwide.

Purpose of the Study:

• To describe the current state of celiac disease diagnosis and treatment patterns.
• To identify barriers to timely and accurate CD diagnosis.
• To highlight unmet needs in CD management and treatment.

Main Methods:

• A targeted literature review was conducted using databases like MEDLINE, Embase, and Cochrane Library.
• Relevant conference abstracts were screened to supplement the literature review.
• The review focused on diagnostic and treatment approaches for celiac disease.

Main Results:

• The standard diagnostic method involves small bowel biopsy via endoscopy, though biopsy-free diagnosis is possible in select cases.
• Diagnostic delays are common, averaging up to 12 years, due to atypical symptoms, physician awareness gaps, and limited specialist access.
• The gluten-free diet (GFD) is the primary treatment, but adherence and efficacy vary, with only one-third of patients receiving regular monitoring.

Conclusions:

• Significant unmet needs exist in improving CD diagnostic accuracy and timeliness.
• Development of novel treatments for refractory and GFD-nonresponsive CD is crucial.
• Further research on gluten-free eating education and food accessibility is recommended to improve patient outcomes.
