Coeliac disease (CD) is a chronic, immune-mediated enteropathy in which dietary gluten triggers an inflammatory reaction of the small intestine in genetically predisposed individuals. The clinical presentation of the disease varies broadly and may include both intestinal symptoms and extra-intestinal manifestations, including iron-deficiency anaemia, osteoporosis, dermatitis herpetiformis, and neurological disorders, such as peripheral neuropathies and ataxia (a condition that affects co-ordination, balance and speech). Many patients who present with neurological manifestations of CD have no gastrointestinal symptoms, commonly leading to a delay in diagnosis. The aim of this systematic review was to assess the prevalence of peripheral neuropathies and gluten ataxia. Nine studies on gluten ataxia and 13 on gluten neuropathy were included in this review. The prevalence of both, neuropathy and ataxia, in the general population is very low, but this risk is increased in patients with CD. Estimates of the prevalence of neuropathy in CD patients ranged from 0% to 39%, with an increased risk in older and female patients. Prevalence of gluten ataxia varied from 0% to 6%. Symptoms of gluten neuropathy improve when patients with CD follow a gluten free diet (GFD), whilst the benefits of a GFD for ataxia vary between studies, possibly due to differences in study design. The authors note that this review primarily concentrated on patients with CD (i.e. those with evidence of enteropathy). However, neurological manifestations may exist in the presence of anti-gliadin antibodies alone (gluten sensitivity without evidence of enteropathy), and such patients benefit equally from a GFD. The authors conclude that patients with CD have an increased risk of gluten ataxia and gluten neuropathy, and that clinicians should check for gluten sensitivity in patients with ataxia and neuropathy of unknown origin.
