Early-life exposure to common virus infections did not differ between coeliac disease patients and controls

Area of Science:

• Pediatric Gastroenterology
• Virology
• Immunology

Background:

• Celiac disease is an autoimmune disorder triggered by gluten ingestion.
• The role of viral infections in the development of celiac disease is not fully understood.
• Previous studies have suggested potential links between viral infections and autoimmune diseases.

Purpose of the Study:

• To investigate the presence of common viruses in stool, nasal swabs, and serum antibodies in children who developed celiac disease compared to controls.
• To explore potential associations between specific viral infections and the onset of celiac disease.

Main Methods:

• A case-control study utilizing the DIABIMMUNE Study cohorts.
• Matched 29 Estonian and Finnish children who developed celiac disease with disease-free controls.
• Collected stool and nasal swab samples at 3-6 months and serum samples at diagnosis.

Main Results:

• Rhinovirus RNA was detected in nasal swabs of 5 celiac disease children, but none of the controls (p=0.05).
• No significant differences in virus-specific antibody levels were observed between cases and controls.
• Enterovirus IgG antibodies were more prevalent in Estonian children compared to Finnish children (63% vs. 23%, p=0.02).

Conclusions:

• This study found no significant overall differences in common viral infections between children who developed celiac disease and controls.
• A slight increase in rhinovirus infections was noted in children who later developed celiac disease.
• Further research is needed to elucidate the precise role of rhinovirus in celiac disease pathogenesis.
