胃蛋白酶原和胃泌素17在诊断萎缩性胃炎中的价值

胃蛋白酶原（pepsinogens,PG）是胃蛋白酶的前体,包括PG Ⅰ和PG Ⅱ。在胃黏膜萎缩时,血清PG Ⅰ和PG Ⅱ浓度随萎缩程度的加重而逐渐降低,因PG Ⅰ降低较PG Ⅱ更为明显,PG Ⅰ/Ⅱ比值降低。PG Ⅰ和（或）PG Ⅰ/Ⅱ比值降低可作为萎缩性胃炎的血清学诊断方法。胃泌素17由胃窦的G细胞产生,其血清浓度取决于胃内酸度和G细胞数量,当胃窦萎缩时其浓度降低、胃体萎缩则升高。血清PG联合胃泌素17诊断萎缩性胃炎的灵敏度、特异度分别为74.7%、95.6%,阴性预测值为91%,可用于胃癌风险的分层和高危人群的胃癌筛查。但血清PG、胃泌素17浓度受幽门螺杆菌感染、质子泵抑制剂使用、年龄、性别等因素影响。

Analysis of serum gastrin-17 and Helicobacter pylori antibody in healthy Chinese population

BackgroundGastrin‐17 (G‐17) and Helicobacter pylori (H pylori) antibody are widely used in the screening of gastric diseases, especially in gastric cancer. In this study, we aimed to evaluate the value of G‐17 and H pylori antibody in gastric disease screening.MethodsHealthy males and females (1368 and 1212, respectively) aged between 21‐80 years were recruited for the study. Serum G‐17 value was measured using ELISA, and H pylori antibodies were measured using Western blotting. Statistical analyses were performed using the chi‐square, Mann‐Whitney U, and Kruskal‐Wallis H tests.ResultsSerum G‐17 level was higher in the H pylori‐positive group than in the negative group. Serum G‐17 level was higher in the type 1 H pylori‐positive group than in the type 2 H pylori‐positive group. Further, serum G‐17 level was higher in females than in males and showed significant differences among different age‐groups, with changes in trend proportional to the age. The positive rate of H pylori infection in all the subjects was 58.29% and did not show a significant difference between males and females. However, it showed significant differences among different age‐groups, with the changing trend proportional to the age.ConclusionAnalysis of serum G‐17 level and H pylori antibody typing is valuable in gastric disease screening. Every laboratory should establish its own reference interval for G‐17 level.     

Ratio between serum IL-8 and pepsinogen A/C: a marker for atrophic body gastritis

BACKGROUND AND AIMS: Elevated serum gastrin and a low pepsinogen A/C ratio are well-recognized markers for atrophic body gastritis (ABG). We have shown that the presence of body atrophy is also associated with elevated serum pro-inflammatory cytokines. This study tested the hypothesis that serum cytokines provide additional information to gastrin and pepsinogens in screening for ABG. METHODS: Two hundred and twenty-six consecutive patients were investigated on referral for upper gastrointestinal endoscopy: 150 were patients with gastro-oesophageal reflux disease, receiving acid inhibitory medication either with proton pump inhibitors (n = 113) or with histamine2-receptor antagonists (n = 37), and 76 were nontreated controls, who had normal endoscopic findings. Gastric mucosal biopsies were sampled for histological examination (Sydney classification). Serum samples were analyzed for gastrin, chromogranin A (CgA), and pepsinogens A and C by RIA, and for the interleukins (IL)-1beta, IL-6, and IL-8 by ELISA. RESULTS: Subjects with ABG had significantly higher serum gastrin (P < 0.01) and serum CgA (P < 0.01) levels and significantly lower pepsinogen A/C ratios (P < 0.001) than those without ABG. Additionally, serum IL-1beta, IL-6 and, especially, IL-8 levels were significantly higher in the subjects with than in those without ABG (P < 0.0001, for all cytokines). To optimize the detection of body atrophy we defined the ABG index: the ratio between the simultaneously measured IL-8 and pepsinogen A/C. The area under the ROC curve for the ABG index was significantly greater than that for serum gastrin and for serum pepsinogen A/C alone (0.91 +/- 0.029 vs. 0.72 +/- 0.042, and vs. 0.83 +/- 0.031, P = 0.018 and P = 0.049). Using the ABG index at a cut-off value of 1.8 pg mL-1, 91% of the cases were classified correctly. CONCLUSIONS: The ratio between serum IL-8 and pepsinogen A/C accurately predicts the presence of ABG. We therefore propose the ABG index as a noninvasive screening test for ABG in population-based studies.     

Association of serum pepsinogen with degree of gastric mucosal atrophy in an asymptomatic population

BACKGROUNDAtrophic gastritis is a precancerous lesion of the stomach. It has been reported that pepsinogen (PG) can reflect the morphology and function of the gastric mucosa, and it is therefore used as a marker for the early diagnosis of atrophic gastritis.AIMTo evaluate the diagnostic value of serum PG for degree of gastric mucosal atrophy in asymptomatic Chinese upon physical examination.METHODSMedical data were collected from subjects who underwent transnasal gastroscopy between October 2016 and October 2018. For each study subject, serum PG levels and presence of Helicobacter pylori (H. pylori) infection were investigated. Pathology was evaluated using the Operative Link for Gastritis Assessment (OLGA) classification and Operative Link on Gastric Intestinal Metaplasia Assessment (OLGIM) systems. All statistical analyses were carried out using SPSS statistical software.RESULTSA total of 2256 subjects were enrolled and 1922 cases were finally included in the study. Based on the OLGA grading system, the levels of PGI were slightly decreased, while those of PGII were slightly increased. The PGI/PGII ratio (PGR) was reduced with increasing atrophy. The association between PG and OLGA grading was higher compared with that between PG and the OLGIM grading system. Compared with the OLGA-0 group, a statistically significant difference was observed in the mean age of OLGA-I, III, and IV groups (P < 0.05). In the H. pylori-positive subjects, the PGR levels were notably lower in the OLGA-I, II, and III groups compared with the OLGA-0 group (P < 0.05). H. pylori-positive subjects exhibited significantly higher PGI and PGII serum levels and a significantly lower PGR compared with H. pylori-negative patients in different OLGA groups (P < 0.05). CONCLUSIONSerum PG levels may represent a non-invasive screening marker for gastric mucosal atrophy in asymptomatic subjects.
