Celiac.com 11/28/2018 - Patients with gluten ataxia without enteropathy have lower levels of antigliadin antibodies (AGA) compared to patients with celiac disease. Magnetic Resonance Spectroscopy (NAA/Cr area ratio) of the cerebellum improves in patients with gluten ataxia following a strict gluten-free diet, and is associated with an improvement in symptoms.
A team of researchers recently set out to present their experience of the effect of a gluten-free diet in patients with ataxia and low levels of AGA antibodies measured by a commercial assay. The research team included Marios Hadjivassiliou, Richard A Grünewald, David S Sanders, Panagiotis Zis, Iain Croall, Priya D Shanmugarajah, Ptolemaios G Sarrigiannis, Nick Trott, Graeme Wild, and Nigel Hoggard. They are variously affiliated with the Academic Departments of Neurosciences and Neuroradiology; the Departments of Gastroenterology, the Departments of Dietetics; the Departments of Immunology, Sheffield Teaching Hospitals NHS Trust, in Sheffield, UK.
The NAA/Cr area ratio from the cerebellar vermis increased in all patients on a strict gluten-free diet, increased in only 1 out of 5 patients on a gluten-free diet with persisting circulating AGA, and decreased in all patients who did not follow a gluten-free diet.
From these results, the team concludes that patients with ataxia and low levels of AGA benefit from a strict gluten-free diet. The results suggest an urgent need to redefine the serological cut-off for circulating AGA in the diagnosis of gluten ataxia.
