[Anti-Helicobacter pylori antibodies in cases of stomach polyps].

UNLABELLED The goal of the study was to study the content of anti-Helicobacter pylori antibodies (at-HP), their diagnostic and prognostic significance for stomach polyps. MATERIALS AND METHODS The content of anti-Helicobacter antibodies (IgG-HP; IgA-HP; IgM + IgG + IgA-CagA-HP) was determined in the blood serum by way of immune-enzyme analysis of 46 patients with stomach polyps. Such test systems as EcoLab (Elektrostal) and Vector-Best (Novosibirsk) were used. RESULTS Stomach polyps are accompanied by a regular increase of at-HP--serologic markers of helicobacteriosis content in the blood serum. The most significant increase in terms of percentage and absolute values is the IgG-HP concentration increase (88%, average titre 1: 1060, in the control group--1: 110) and summary (IgM + IgG + IgA) antibodies to CagA-HP (86%, average titre 1 : 180, in the control group 1 : 10), while the IgA-HP level is increased in 46%, average titre 1 : 660, in the control group 1 : 120). The IgG-HP content increase reflects the inflammatory process intensity, IgA-HP--atrophic process intensity, (IgM + IgG + IgA)-CagA-HP--1 intensity of proliferative processes of stomach polyps. CONCLUSION The at-HP content increase is a diagnostic criterion for helicobacteriosis and reflects the intensity of infectious, inflammatory, atrophic and proliferative processes in cases of stomach polyps. A multiple long-lasting increase of the at-HP concentration may be one of the indications for administering an antihelicobacter stomach polyp therapy including administration before polypectomy.
