ABSTRACT

Background: Endoscopic screening is an effective approach for detecting early gastric cancer. The interval of endoscopic surveillance should be defined based on the risk stratification of gastric cancer, so as to improve the screening efficiency. Aims: To investigate whether gastric cancer risk could be stratified according to endoscopic atrophic gastritis grading. Methods: Subjects who underwent gastroscopy at least two times between Jan. 2015 and Dec. 2019 at the 900th Hospital of Joint Logistics Support Force, PLA were enrolled in a retrospective study. The demographic data and information on endoscopy were recorded. The extent and degree of gastric atrophy under endoscopy was graded using Kimura-Takemoto classification system. Then the subjects were allocated into mild group (none atrophy and C-1), moderate group (C-2 and C-3) and severe group (O-1, O-2 and O-3) based on the grading. The correlation of endoscopic grading of atrophy with the risk of gastric cancer was analyzed. Results: A total of 8 736 subjects were enrolled, 4 154 were in mild group (47.6%), 2 409 in moderate group (27.6%), and 2 173 in severe group (24.9%). The mean endoscopic follow-up time was (1 052±643) d, and the mean endoscopic surveillance interval was (518±271) d. The overall coincidence rate of endoscopic diagnosis and pathological diagnosis for atrophy was 88.9%. During the follow-up period, gastric cancer was detected in 41 cases; the detection rates of mild group, moderate group and severe group were 0.07%, 0.54% and 1.15%, respectively (P<0.001). Conclusions: The risk of gastric cancer can be stratified according to the endoscopic atrophic gastritis grading, which is helpful for the decision of individualized endoscopic surveillance interval.

ABSTRACT

Purpose To analyze clinicopathologic and prognostic features in 9 cases of children endocapillary proliferative glomerulone-phritis with hepatitis B virus antigen deposition ( HBV-ECPGN) . Methods Retrospective analysis of demographic information, clini-cal manifestations, laboratory parameters, pathological and prognostic features was carried out for 9 cases of HBV-ECPGN and 13 cases of acute poststreptococcal infection endocapillary proliferative glomerulonephritis ( APS-ECPGN) for comparison. Renal biopsy tissue were fixed in formalin and embedded in paraffin, stained with HE, PAS and PAM-Masson. Immunohistochemical study with EliVision method was performed. Three cases were submitted for electron microscopy. Results There were 7 males and 2 females ( M ∶ F=7 ∶ 2) of HBV-ECPGN. The median age was 10. 3 years. Serum C4 deposition ratio HBV-ECPGN was significantly greater than APS-ECPGN group (P<0. 05). There was an average of 11. 2 weeks of HBV-ECPGN kidney disease duration, which was significantly lon-ger than an average of 3. 8 weeks of APS-ECPGN group (P<0. 05). There was no disease relapse in all cases during 53. 55 months follow-up. C4d deposit was significantly stronger in all HBV-ECPGN cases compared with control group (APS-ECPGN cases). There were no significant differences in deposit of IgG, IgM, IgA, C3d and C1q between the two groups. HBsAg deposit in juxtaglomerular sites was identified in all cases. Conclusions Serum C4 decrease is more common in HBV-ECPGN than APS-ECPGN. Which may be associated with HBV infection, there is longer disease duration of HBV-ECPGN. C4d deposit is significantly stronger than control group, suggesting pathogenesis of HBV-ECPGN and APS-ECPGN is different. HBsAg deposit may be closely related to the pathogene-sis of HBV-ECPGN. HBsAg deposit in juxtaglomerular sites may be characteristic of HBV-ECPGN.
