Introduction Previous studies have shown a close relationship between Helicobacter pylori (H. pylori), insulin resistance, and altered metabolic parameters. However, the effects of H. pylori eradication on these conditions remain controversial. We carried out a systematic review and meta-analysis to evaluate the effects of H. pylori eradication on insulin resistance and metabolic parameters.

Methods We searched CENTRAL, MEDLINE, and EMBASE databases from their inception to July 2016. Insulin resistance (HOMA-IR), body weight (BW), BMI, waist circumference, triglycerides (TG), high-density and low-density lipoprotein-cholesterol (HDL-C and LDL-C), and fasting blood glucose (FBG) were compared between patients with and without H. pylori eradication using a random-effects model. We reported pooled mean differences (MD) and 95% confidence intervals (CI) for the change in outcomes.

Results Data from five studies showed no difference in HOMA-IR after H. pylori eradication (pooled MD=−0.52, 95% CI: −1.47 to 0.42). Eradication significantly increased BMI (MD=0.36, 95% CI: 0.11–0.60) and BW (MD=1.1, 95% CI: 0.8–1.5), but had no significant effects on TG, LDL-C, HDL-C, or FBG.

Conclusion H. pylori eradication does not improve insulin resistance, TG, HDL-C, LDL-C, or FBG, but may increase BW and BMI. Further studies are needed to clarify the effect of H. pylori eradication on metabolism.
