[Immunofluorescence in the determination of gliadin antibodies in celiac disease].

IgG gliadin antibodies (AGA-IgG) were detected by immunofluorescence in 78 celiac children diagnosed by jejunal biopsy. AGA-IgG were also detected in patients affected by other gastrointestinal disease, in patients with diabetes, in health children and in children with normal mucosa. AGA-IgG were found in 81% of celiac patients, while they were not detected in patients affected by other intestinal or extraintestinal diseases, neither in healthy controls. It is conclude that determination of AGA-IgG is a very specific and sensitive enough screening test before small intestinal biopsy.
