The association of anti-gliadin and anti-transglutaminase antibodies and chronic plaque psoriasis in Indian patients: Preliminary results of a descriptive cross-sectional study.

Significant elevation of serum anti-transglutaminase and anti-gliadin antibodies levels is noted in psoriasis patients reflecting a possible link. However, results need careful interpretation for any significance of gluten sensitivity in pathogenesis of psoriasis/arthritis or as a stand-alone risk factor for chronicity/severity of psoriasis or whether gluten-free diet will be ameliorating. Small number of subjects, cross-sectional study design, lack of pathological/endoscopic diagnosis and follow-up are study limitations.
