[Phenotype characteristics of humoral immunity parameters in patients with chronic generalized periodontitis with...

Interrelationships between parameters of humoral immunity with AB0 blood groups have been investigated. The highest content of IgA to transglutaminase was found in A(II) patients, while the lowest content was found in AB(IV) patients. The blood content on anti-gliadin IgA was higher in healthy donors. The oral liquid of periodontic patients contained anti-gliadin IgA and IgB lacking in healthy donors. It have been found that 47% of healthy people and 52.7% of patients are infcted with Helicobacter pylori. In the group of periodontic patients A(II) individually predominated; they were characterized by the presence of antibodies to H. pylori in the oral liquid, these antibodies were absent in healthy donors. The pepsinogen level was higher in blood of periodontic patients than in healthy donors. B(III) patients had the lowest level of blood pepsinogen.
