Correlation of Celiac Diseases with Candida Spp. Based on Anti-gliadin Antibodies

抄録

Summary: A variety of Candida spp. can be found as a natural commensal fungus in various parts of the human body. This fungus may be associated with various diseases such as celiac disease (CD). Gliadin, a component of the gluten protein complex that is mostly found in wheat, is the main inducer of CD. A number of studies have demonstrated that patients infected with Candida can develop CD, and vice versa. C. albicansis presumed to induce CD because it has a protein homologous to gliadin in its cell wall called Hwp1. Despite the non-specificity of the anti-gliadin test, the detection of antibodies against anti-gliadin (AGA) and anti-tissue transglutaminase (anti-tTG) are important in the diagnosis of CD. Some evidence is now available to support the hypothetical correlation between Candida spp. and CD, as high levels of AGA have been found in patients infected with candidiasis without CD. Further study is needed to confirm this relationship.
