Significant factors associated with GERD were education level, economic level, asthma status, and delayed gastric emptying. Studies with larger numbers of subjects needed to analysed factors which related with

Socioepidemiological; Presenting Author: UDAYCHAND GHOSHAL Additional Authors: SUSHIL KUMAR, SAMIR MOHINDRA, RD MITTAL Corresponding Author: UDAYCHAND GHOSHAL Affiliations: SGPGIMS, Lucknow Objective: IL-8–251T/A and IL-10 (-1082G/A, -819C/T, -592C/A) polymorphisms may influence gastritis, RAD001 solubility dmso gastric atrophy, intestinal metaplasia (IM) and gastric cancer (GC) following H. pylori infection altering their expression. Methods: Genotyping of these genes was performed (ASO-PCR) in 180

each patients with GC and functional dyspepsia (FD) and 250 healthy subjects (HS). Serum IgG-antibody against H. pylori was tested in all subjects and IL-8 and IL-10 were measured in 60 subjects in each group using commercial ELISA. Results: IL-8 AA and IL-10–819 TT (-592 AA) genotypes were commoner among GC than HS (43/180 [23.9%] vs. 35/250 [14.0%]; OR 1.9 [1.09–3.3], p = 0.022 and 35/180 [19.4%] vs. Saracatinib solubility dmso 30/250 [12.0%]; OR 2.03 [1.12–3.7], p = 0.02) but comparable with FD (35/180 [19.4%], p = 0.59 and 35/180 [19.4%], p = 0.68). IL-8 AA and Il-10 -819 T allele carriers were commoner in H. pylori-infected patients with GC than HS (28/101 [27.7%] vs. 22/168 [13.1%]; OR 2.8 [1.38–5.71], p = 0.004 and 18/101 [17.8%] vs. 21/168 [12.5%]; OR 1.7 [1.01–2.96], p = 0.046, respectively). IL-10–1082 G/A genotype and IL-10 haplotypes (ACC, GCC, ATA and GTA) were comparable in all groups. IL-8 level was higher among patients with GC and FD than HS (57.64 [6.44–319.46] vs. 54.35 [4.24–318.96] vs. 26.33 [4.67–304.54] pg/ml, and respectively; p = ns for GC vs. FD and p < 0.0001 for GC vs. HS). IL-10 level was lower in patients with GC

Cyclin-dependent kinase 3 than HS and among H. pylori-infected than non-infected subjects (3.79 [1.24–56.65] vs. 15.468 [1.01–27.86], p = 0.0001 and 8.34 [1.24–54.43] vs. 12.28 [0.96–64.87], p = 0.012 pg/ml). Conclusion: IL-8–251AA and IL-10 -819TT gene polymorphisms is associated with GC. These cytokines may play role in H. pylori-associated gastric carcinogenesis in India. Key Word(s): 1.
