BACKGROUND/AIMS: Helicobacter pylori (H. pylori) infection is known as a major cause of atrophic gastritis and is associated with serum gastrin, pepsinogen, and gastric acid secretion. There is still a controversial association between gastroesophageal reflux disease and H. pylori infection. This study was designed to investigate the relationship among serum gastrin, pepsinogen, and H. pylori infection in the erosive reflux esophagitis (ERD) patients. METHODS: Patients who were diagnosed as ERD by one gastroenterologist at the Kangnam St. Marys hospital were prospectively enrolled. The persons without ERD in the control group were matched for age and sex. We examined the gastrin, pepsinogen I (PG I), PG II, PG I/II ratio, and H. pylori infection. RESULTS: Forty five patients were enrolled in ERD group and 66 persons in control group. The H. pylori infection rate in ERD group was lower than that in the control group (11.1% vs. 43.9%, p<0.001). PG I/II ratio in ERD group was higher than that in the control group (7.0+/-3.1 vs. 5.3+/-2.6, p=0.003). The PG II (p=0.016) and gastrin (p=0.029) in ERD group were lower than those in the control group. BMI in ERD group was higher than that in the control group (24.5 vs. 23.1 kg/m(2), p=0.013). CONCLUSIONS: The H. pylori infection rate in ERD group was lower and PG I/II ratio was higher than that in the control group. Reflux esophagitis is thought to be reversely associated with the atrophy of gastric mucosa.

Serum gastrin and pepsinogen concentrations were measured in 51 children infected with Helicobacter pylori, to investigate the clinical significance and influence of CagA and VacA on serum concentrations of these peptides. CagA+ was 44/51 (86%) and VacA+ was 42/51 (82%). Type I (CagA+/VacA+) included 39/51 (76%), type II (CagA-/VacA-) was 4/51 (8%), and intermediate (CagA-/VacA+, CagA+/VacA-) was 8/51 (16%). There was no significant correlation between endoscopic diagnosis and the state of CagA/VacA. Serum gastrin concentrations were not significantly correlated with the state of CagA/VacA. Serum pepsinogen I and II concentrations were significantly higher in CagA+ than in CagA-, but there was no significant difference between VacA+ and VacA-, Serum pepsinogen I/II ratio was not significantly correlated with the state of CagA/VacA. There was no significant difference between serum concentrations of gastrin, pepsinogen I and H. pylori phenotypes. However, pepsinogen II concentration was significantly higher in type I than type II. Pepsinogen I/II ratio was significantly lower in type I and intermediate than in type II. These findings suggest that CagA positively and phenotype of H. pylori could play a role in the development of upper gastrointestinal diseases in children.

OBJECTIVETo find out the connection of serum pepsinogen and it's subgroups (PGI, PGII) with CA72-4 to early diagnosis and postoperative recurrence on gastric cancer.

METHODSRIA was applied to detect the results of serum PGI, PGII and CA72-4 on gastric cancer and other stomach diseases, then the clinic value of associating detection on gastric cancer diagnosis and prognosis judgment were assessed.

RESULTSThe serum PG levels of GC patients were significantly lower comparing to those of healthy controls (P < 0.01), apparent changes had taken place on earlier period GC (P < 0.05), and aggressive GC were even lower (P < 0.01). On the earlier period of GC diagnosis, CA72-4 levels were not apparently different to healthy controls (P > 0.05), and aggressive GC were significantly higher (P < 0.01). Compared preoperative with postoperative, the serum PGI and PGII and CA72-4 levels were significantly different (P < 0.01). In the patients underwent total gastrectomy, both of pepsinogen levels were lower than those of subtotal or large partial gastrectomy (P < 0.05). The serum PGI, PGII and CA72-4 levels of patients with recurrence of GC after total gastrectomy were significantly higher than those without. Compared before recurrence patients with after ones, the serum PGI and PGII levels of partial gastrectomy were no apparent difference (P > 0.05), however apparent changes had taken place on CA72-4 levels. The associate detection had even higher specificity (P < 0.01).

CONCLUSIONSApply to detect the serum PG levels on crowds, especially pGI, PGI/II levels decrease, which may be expected to become the index to earlier period GC screening. The associating detection to PG and CA72-4 levels may significantly improve sensitivity and specificity, which have chances to be applied to monitoring to postoperative gastrectomy.

BACKGROUND: Helicobacter pylori infection and subsequent gastric inflammation have been proposed as risk factors for the development of insulin resistance and cardiovascular disease. In this study we assessed the possible association of H. pylori bacterial load, and serum biomarker of gastric inflammation with cardiometabolic risk factors in diabetic patients. METHODS: In this cross-sectional study, 84 H. pylori-infected type 2 diabetic patients were assessed for anthropometrics, biochemical and clinical measurements. Pearson correlation test, linear, and logarithmic regression curve estimation models were used to assess the association of H. pylori stool antigen (HpSAg) levels, and pepsinogen I (PGI) to pepsinogen II (PGII) ratio with fasting serum glucose, insulin, serum lipid and lipoprotein parameters, malondialdehyde, high-sensitive C-reactive protein (hs-CRP), systolic and diastolic blood pressure, body weight, waist circumference and lipid accumulation product (LAP) index. RESULTS: The mean age of participants was 54+/-10 years, and 44% were men. Mean HpSAg levels and PGI/PGII ratio were 0.24+/-0.23 microg/mL and 9.9+/-9.0, respectively. Higher HpSAg as well as lower PGI/PGII was correlated with higher anthropometric measures and LAP. A significant negative correlation between PGI/PGII ratio and blood pressure (r=-0.21 and r=-0.22, systolic and diastolic, respectively, P<0.05), serum insulin (r=-0.17, P=0.05), and hs-CRP (r=-0.17, P=0.05) was observed. A significant linear association between PGI/PGII ratio with serum triglycerides (beta=-0.24, P<0.05), serum high density lipoprotein cholesterol (HDL-C; beta=0.43, P<0.01), and triglycerides/HDL-C ratio (beta=-0.28, P<0.05) were observed. CONCLUSION: Higher H. pylori bacterial load and lower PGI/PGII ratio was associated with higher levels of cardiometabolic risk factors in H. pylori infected type 2 diabetic patients.
