The aim of the current study was to test the prevalence of tissue transglutaminase 2 (anti-TG2), tissue transglutaminase 6 (anti-TG6), and gliadin antibodies (anti-gliadin) in a large cross-sectional study. The sera of patients with idiopathic cerebellar ataxia, idiopathic small fibre neuropathy (SFN) and chronic idiopathic axonal polyneuropathy (CIAP), and controls with a comparable age distribution and men\/women ratio were collected. The sera were analysed for anti-gliadin IgA\/IgG (manufacturer\u2019s and lower cut-off), anti-TG2 IgA and anti-TG6 IgA\/IgG. In total, 683 samples were analysed: 476 patients (249 SFN, 161 CIAP and 66 idiopathic cerebellar ataxia) and 195 controls. There were no differences between disease and control group in the prevalence of elevated anti-TG6, anti-TG2 and anti-gliadin using the manufacturer\u2019s cut-off. Using a lower cut-off of 3 U\/mL, previously used by others for gluten-related neurological disorders, anti-gliadin IgA was positive in 20.8% patients vs 12.8% controls (\n                    <jats:italic>p<\/jats:italic>\n                    \u2009=\u20090.017) and anti-gliadin IgG in 7.6% vs 2.6% (\n                    <jats:italic>p<\/jats:italic>\n                    \u2009=\u20090.013), respectively. In subgroup analyses, significant differences were only observed in SFN for anti-gliadin IgA and in idiopathic cerebellar ataxia for anti-gliadin IgG using this lower cut-off after adjusting for sex and age. In conclusion, no difference in anti-TG2, anti-TG6 and anti-gliadin levels were observed between patients and controls. Only when using the lower cut-off (3 U\/mL), the patients with SFN and idiopathic cerebellar ataxia were more often positive for anti-gliadin than controls. Whether these low-titre antibodies are gluten related, have any pathophysiological relevance, or reflect an epiphenomenon of neurodegeneration or gut inflammation is unknown.\n                  <\/jats:p>","DOI":"10.1007\/s00415-025-13187-w","type":"journal-article","created":{"date-parts":[[2025,6,7]],"date-time":"2025-06-07T02:52:05Z","timestamp":1749264725000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Serological analysis of gluten-related antibodies in idiopathic neuropathies and cerebellar ataxia"],"prefix":"10.1007","volume":"272","author":[{"given":"Maxine D.","family":"Rouvroye","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Janna","family":"Warendorf","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alexander","family":"Vrancken","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Filip","family":"Eftimov","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Luuk","family":"Wieske","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Catharina G.","family":"Faber","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Janneke G.
