Does cryptic gluten sensitivity play a part in neurological illness?

Area of Science:

• Neurology
• Gastroenterology
• Immunology

Background:

• Antigliadin antibodies are markers for celiac disease but can be present in individuals without small-bowel abnormalities.
• Neurological dysfunction is a recognized complication of celiac disease.
• The study investigates the prevalence of antigliadin antibodies and celiac disease in neurological patients.

Purpose of the Study:

• To determine the frequency of antigliadin antibodies in neurological patients.
• To assess the association between antigliadin antibodies and neurological dysfunction of unknown cause.
• To explore the etiological significance of gluten sensitivity in neurological diseases.

Main Methods:

• Serum IgG and IgA antigliadin antibodies were measured using ELISA in 147 neurological patients and 50 healthy controls.
• Neurological patients were categorized into two groups: those with unexplained neurological dysfunction (n=53) and those with a specific neurological diagnosis (n=94).
• Duodenal biopsies were performed on antigliadin-positive patients from the unexplained neurological dysfunction group.

Main Results:

• Elevated antigliadin antibody titers were found in 57% of patients with unexplained neurological dysfunction, compared to 5% in the neurological control group and 12% in healthy donors.
• Histological examination of duodenal biopsies revealed celiac disease in 35% of antigliadin-positive patients with unexplained neurological dysfunction.
• Non-specific duodenitis was observed in 38% and no lesions in 26% of these patients.

Conclusions:

• Gluten sensitivity, indicated by antigliadin antibodies, is prevalent in patients with neurological diseases of unknown origin.
• These findings suggest that gluten sensitivity may play a significant role in the etiology of unexplained neurological conditions.
• Further research is warranted to elucidate the mechanisms linking gluten sensitivity and neurological dysfunction.
