Evaluation of the Prevalence of Anti-Transglutaminase 2 and 6 Antibodies in Patients With Sero-Positive Multiple Sclerosis Publisher

Summary: Could gluten sensitivity (GS) be linked to multiple sclerosis (MS)? A study found 9.7% of MS patients had tTG-6 autoantibodies, suggesting early testing may help. #GlutenSensitivity #MultipleSclerosis

Abstract

Background: Gluten sensitivity (GS) is one of the gluten-related disorders (GRDs). Patients with GS may have serum antibodies against tissue transglutaminase (tTG) (IgA and IgG) without any evidence of enteropathy. We aimed to evaluate both tTG-6 and tTG-2 antibodies to determine the prevalence of seropositive tTG-2 and tTG-6 antibodies in patients with multiple sclerosis (MS). Methods: In this cross-sectional study, we carried out serological tests (IgA & IgG anti-tTG-6 and tTG-2 antibodies) in patients with MS. Results: Seventy-two patients with MS were included in this study. Of them, seropositive patients for total (IgA+IgG) of tTG-6 and tTG-2 autoantibodies were 9.7% (95% CI, 4.2-18) and 5.6% (95% CI, 1.4-12.5), respectively. Conclusion: Anti-tTG-6 antibody testing may be necessary for early diagnosis of GS in patients with MS. More studies with larger sample sizes are warranted to confirm these data. © 2024 The Author(s).
