RESUMEN
BACKGROUND/AIMS: The long-term effect of Helicobacter pylori eradication on the metabolic syndrome or diabetes are unclear. The aim of this study was to evaluate the effect of H. pylori eradication on glycemic control in type 2 diabetes mellitus (T2DM) or prediabetes mellitus (preDM). METHODS: A total of 124 asymptomatic subjects with T2DM or preDM were divided into H. pylori-negative (n = 40), H. pylori-positive with non-eradicated (n = 34), and eradicated (n = 50) groups. We measured H. pylori status (culture, histology, and rapid urease test) and glycated hemoglobin A1c (A1C) levels and followed-up at the 1st year and the 5th year of follow-up. RESULTS: The A1C levels significantly decreased in the eradicated group compared to the negative group and the non-eradicated groups (at the 1st year, p = 0.024; at the 5th year, p = 0.009). The A1C levels decreased in male, and/or subjects < 65 years of age in subgroup analyses (in male subjects, p = 0.047 and p = 0.020 at the 1st and the 5th year; in subjects < 65 years of age, p = 0.028 and p = 0.006 at the 1st and the 5th year; in male subjects < 65 years of age, p = 0.039 and p = 0.032 at the 1st and the 5th year). The eradication of H. pylori was related to the decrease in A1C values throughout the follow-up period, compared to the non-eradicated group (p = 0.017). CONCLUSION: H. pylori eradication was related to the decreasing of A1C levels in patients with T2DM or preDM over a long-term follow-up period, especially in male and subjects < 65 years of age.

BACKGROUND AND AIM: Few studies have evaluated the change in serum pepsinogen (sPG) levels after the eradication of Helicobacter pylori. The aim of this study was to evaluate the effect of H. pylori eradication on sPG levels in patients with gastric cancer/dysplasia in comparison to a control group. METHODS: We prospectively enrolled 368 patients with gastric cancer/dysplasia and 610 control subjects. H. pylori status and sPG levels were measured before and after eradication. The follow-up time points were classified as < 12, 12-23, 24-35, and ≥ 36 months. RESULTS: In 179 H. pylori-eradicated patients with gastric cancer/dysplasia and 168 control group subjects, sPG I significantly decreased, and the sPG I/II ratio significantly increased after eradication compared to baseline, and this improvement in sPG values was maintained during all follow-up time points. Significant differences in sPG I and the sPG I/II ratio were observed between the gastric cancer/dysplasia group and the control group < 24 months after eradication. However, these differences in sPG values disappeared after ≥ 24 months of follow up. Moreover, significant differences in the intestinal metaplasia grade were observed between these two groups before eradication until < 24 months after eradication. However, these differences in the intestinal metaplasia grade disappeared after ≥ 24 months of follow up in the corpus. CONCLUSION: The sPG values and intestinal metaplasia grade (corpus) in the gastric cancer/dysplasia group became similar to those in the control group at long-term follow up after H. pylori eradication. It might be related with the reduction of metachronous gastric neoplasm.
