Abstract:
Background:Chronic atrophic gastritis(CAG)is a common disease of digestive system and is a precancerous lesion of the intestinal type gastric cancer. Serum pepsinogens(PGs)and gastrin 17(G17)are biological markers of gastric mucosal lesions,which have a prominent role in diagnosis of CAG and screening of early gastric cancer. Aims:To study the correlation of serum PGs and G17 with age in patients with CAG. Methods:A total of 582 CAG patients admitted from Jan. 2016 to Sep. 2017 at the Baoding First Central Hospital were enrolled. The levels of serum PGⅠ,PGⅡ and G17 were determined by ELISA,and the PGⅠ/ PGⅡ ratio(PGR)was calculated. The correlations of these indices with the clinical data of CAG patients were analyzed. Results:The levels of serum PGⅠ and PGⅡ were increased with age(P<0.01),and the levels of PGR and G17 were decreased with age(P <0.05). Spearman rank correlation coefficient analysis showed that the levels of PGⅠ and PGⅡ were positively correlated with age(rs=0.374,P<0.01;rs=0.559, P<0.01),and the levels of PGR and G17 were negatively correlated with age(rs= -0.649,P<0.01;rs= -0.141, P<0.05). Conclusions:The levels of serum PGⅠ,PGⅡand G17 in patients with CAG were correlated with age. When serum PGs and G17 are used as serological indicators for diagnosis of CAG and screening of early gastric cancer,the impact of age on these indices should be taken into account.
