Early Infant Feeding Practices May Influence the Onset of Symptomatic Celiac Disease

Area of Science:

• Pediatric Gastroenterology
• Immunology
• Nutrition Science

Background:

• Celiac disease (CD) is an autoimmune disorder triggered by gluten ingestion.
• Infant feeding practices, including breastfeeding and timing of gluten introduction, are hypothesized to influence CD development and diagnosis.
• Understanding these factors is crucial for early detection and management of pediatric CD.

Purpose of the Study:

• To investigate the impact of breastfeeding and its status during gluten introduction on the age of celiac disease diagnosis.
• To determine if the timing of gluten introduction influences the age at which celiac disease is diagnosed in children.

Main Methods:

• A hospital-based observational study included 198 pediatric patients diagnosed with celiac disease (CD) aged 6 months to 6 years.
• Detailed patient histories were collected, focusing on breastfeeding practices and the age of gluten introduction.
• Statistical analysis was performed to evaluate the relationship between feeding practices and CD diagnosis age.

Main Results:

• Patients who were breastfed were diagnosed with CD at a later age (3.68±1.55 years) compared to non-breastfed patients (2.70±1.65 years; p<0.05).
• Continuing breastfeeding during gluten introduction and for longer durations significantly delayed disease onset.
• Introducing gluten before 6 months of age was associated with earlier CD onset (under one year in 40.42% of cases) compared to later introduction (12.58%; p<0.001).

Conclusions:

• Delayed gluten introduction and continued breastfeeding are associated with a delayed symptomatic presentation of celiac disease (CD).
• These infant feeding strategies appear to postpone the onset of CD symptoms.
• The study could not ascertain whether these practices provide lasting protection or merely delay the manifestation of celiac disease.
