Helicobacter pylori (H. pylori) infection in patients with chronic renal failure plays an important role in the pathogenesis of upper gastrointestinal tract diseases. In our earlier study we did not find significant relationship between parathormone (PTH) concentration abnormalities and H. pylori infection in hemodialysis patients (HD pts). The aim of our present study was to examine other parameters and interrelationships between them, connected with H. pylori infection in HD pts. The serum concentration of the following substances were measured: gastrin (G), parathormone (PTH), and IgG antibodies against H. pylori. The study was conducted in 65 (36 M, 29 F) stable HD pts: age 49 +/- 12 years, dialysed from 6 to 288 months. The control group (CG) consisted of 15 healthy people, mean age 38 +/- 8 years. The mean concentration of serum PTH serum was significantly higher in HD pts than in CG (538 +/- 520 vs 35 +/- 9.3 pg/ml, p < 0.001). The mean concentration of gastrin in serum was significantly higher in HD pts than in CG (155.37 +/- 235.4 vs 87.97 +/- 9.5 pg/ml, p < 0.01). The mean concentrations of IgG antibodies against IgG H. pylori was similar in HD pts and CG (88.1 +/- 80.0 vs 91.34 +/- 66.8 U/ml). We found significant positive correlation between IgG antibodies against H. pylori infection and gastrin level in serum of HD pts (r = 0.315, p < 0.001). We did not find significant correlation between concentrations: PTH vs G and PTH vs IgG against H. pylori.
Conclusion: Helicobacter pylori infection contributes to hypergastrinaemia in hemodialysed patients. There is no relationships between PTH abnormalities and H. pylori infection.
