Subjects positive for antigliadin antibodies (IgG-AGA+; IgA-AGA+), antiendomysium antibodies (IgG₁-EMA+; IgA-EMA+), and antitissue transglutaminase antibodies (IgG-anti-tTG+; IgA-anti-tTG+) among patients with coeliac disease(CD) affected or not by selective IgA deficiency (IgAD) and in healthy controls
