Analysis of serum gastric function and Helicobacter pylori infection in patients with gastric hyperplastic polyps and gastric fundic gland polyps / 中国综合临床

ABSTRACT

Objective To analyze the serum gastric function and Helicobacter pylori ( HP ) infection in patients with gastric hyperplastic polyps and gastric fundic gland polyps.Methods From December 2017 to December 2018, 135 patients with gastric polyps and pathologically confirmed gastric hyperplastic polyps and gastric fundic gland polyps were enrolled in the hospital of Xuzhou Medical University.Among them, 68 patients with hyperplastic polyps, 67 cases of the gastric fundic gland polyps.Serum Hp antibodies ( UreA, UreB, VacA, CagA antibodies ) were qualitatively detected by immunoblotting.Eighty patients with chronic superficial gastritis were selected as the control group.Three groups of serum pepsinogen?I ( PG?I),pepsinogen?Ⅱ( PG?Ⅱ),gastrin were detected by enzyme?linked immunosorbent assay (ELISA).Gastrin?17( G?17) and calculate PGⅠ and PGⅡ ratio( PGR).Results The levels of serum PGⅡ(13.13(8.15,20.30) μg ／L) and G17 (8.44(3.72,27.17) pmol／L) in the gastric hyperplastic polyp group were higher than those in the control group (9.16(5.56,15.14) μg／L and 1.83(0.87,5.95) pmol／L) ( P＜0.05),and the PGR level was lower than the control group ( P＜0.05);serum PGI ( 120.12 ( 86.72,174.70) μg／L), PGII ( 11.92 ( 7.27,22.26) μg／L),G17 ( 5.68 ( 1.79, 14.65) pmol／L) in the gastric fundic gland polyp group was higher than the control group (( 101.32 (79.17,131.33) μg ／L,9.16 ( 5.56,15.14) μg ／L,1.83 ( 0.87,5.95) pmol／L) ( P 均＜0.05)) ( P＜0.05); serum G17 (8.44(3.72,27.17) pmol／L) level in gastric hyperplastic polyp group was higher than gastric fundus polyp group (5.68(1.79,14.65) pmol／L) ( P＜0.05); Hp infection rate in gastric hyperplastic polyp group61.76%(42／68)was higher than that in the gastric fundic gland polyp group40.30%(27／67) (P＜0.05),and type I Hp was the main one (P＜0.05).The serum PGⅡ and G17 levels in the gastric hyperplastic polyp group were higher than those of Hp negative ( all P＜0.05).There were no significant differences in serum PGI, PGⅡ, G17, and PGR levels between the HP?positive and negative?positive patients in the gastric fundus polyp group.The serum PGI and PGR levels in the hypertrophic polyp group were higher than those in the HPⅡ type ( all P＜0.05).There was no significant difference in the levels of serum PGⅠ,PGⅡ,G17,and PGR between the gastric fundic gland polyps group and the type Ⅱ.Conclusion Serum PG and G17 levels in patients with gastric hypertrophic polyps and gastric fundic gland polyps are higher than those in patients with chronic superficial gastritis.Patients with gastric hyperplastic polyps have higher HP infection rate and abnormal gastric function than gastric fundic gland polyps.
