Gluten sensitivity and celiac disease show no link to ALS

What it found

In people, gluten-related antibodies, celiac disease, and gluten-free diets were about the same in ALS patients and controls.

Genetic data also showed no overlap between celiac disease and ALS.

What they found

Studies in people

Antibodies in people

Gluten-related antibody levels and positivity were similar in ALS patients and controls. One patient had antibodies to TG6, TG2 and EMA but had typical ALS and no gluten sensitivity symptoms.

Celiac disease and diet

The proportion of people with celiac disease or following a gluten-free diet was similar in patients and controls. Patients on a gluten-free diet had an average survival of 3.3 years, consistent with standard ALS progression.

Other findings

Genetics

Genetic analysis found no correlation between celiac disease and ALS. Celiac disease-associated HLA allele frequencies were similar in patients and controls.

What the authors conclude

“In conclusion, we found no serological evidence for involvement of gluten-related antibodies in ALS etiology nor did we observe an association between CD and ALS in medical history or genetic data, indicating that there is no evidence in our data for an association between the two diseases.”

Also in their conclusions

  • They found no serological evidence for involvement of gluten-related antibodies in ALS etiology nor did they observe an association between CD and ALS in medical history or genetic data.
  • They state that there is no evidence in their data for an association between the two diseases.
  • They conclude that a role for a gluten-free diet in ALS treatment seems unlikely.

How it was done

Some studies had suggested a possible link between celiac disease or gluten sensitivity and ALS, and a gluten-free diet was being investigated as a treatment. The authors wanted to examine the evidence for a role of gluten sensitivity or celiac disease in ALS.

They compared gluten-related antibodies in 359 ALS patients and 359 matched controls, and in a subset of 199 patients and 199 controls. They also looked at questionnaire data from 1829 ALS patients and 3920 controls for celiac disease or a gluten-free diet, and analysed genetic data from large studies of ALS and celiac disease.

What it can’t tell you

  • This study looked at whether gluten sensitivity or celiac disease is linked to ALS. It cannot show whether a gluten-free diet would help or harm ALS patients.
  • The genetic analyses used data from people of European descent, so the results may not apply to other populations.
