Abstract:
Objective To explore the expression and significance of CXCL13 in gastric mucosa of children with nodular gastritis. Methods A total of 216 pediatric patients with clinically diagnosed gastritis under gastroscopy were randomly divided into nodular group and non-nodular group according to whether there were nodular changes under endoscopy. The pathological characteristics of gastric mucosa and the expression of CXCL13/CXCR5 in gastric mucosa of all patients were evaluated. Results The infection rates of Helicobacter pylori(HP)in gastric mucosa in nodule group(n=102)and non-nodular group(n=114)were 70.59% and 42.11%, respectively; the rate of severe mononuclear cell infiltration were 74.51% and 22.81%, respectively; the proportion of neutrophil infiltration were 62.75% and 33.33%, respectively; lymph follicles occurred in 64.71% and 20.18%, respectively; and there were statistical differences between the two groups (P<0.001). Positive staining of CXCL13 and CXCR5 were found in the gastric mucosa of all HP infected patients. The percentages of positive cells of CXCL13 and CXCR5 in the gastric mucosa of the nodules group were (71.33±7.14)% and (73.54 ± 7.92)%, which were higher than those in the non-nodule group (45.88 ± 5.92)% and (50.42 ± 5.98)%, respectively, and there were statistical differences (P<0.001). Conclusions Nodular gastritis in children is mainly associated with Hp infection. The expression of CXCL13/CXCR5 is increased in gastric mucosa in children with Hp infection, especially in nodular gastritis, it may be involved in the formation of lymphoid tissue in gastric mucosa.
