Comparison of test-meal induced changes in plasma acyl-ghrelin and leptin levels according to H. pylori at baseline and after eradication. Data are for seven H. pylori-negative, 21 H. pylori-positive subjects including eight H. pylori+cagA- and 13 H. pylori+cagA+ subjects. (* P < 0.05, comparing either pre-meal to post-meal values, or **comparing the first and second evaluations). Data also are shown for all of the 38 H. pylori-negative subjects at baseline, for comparison with the subset who also had follow-up studies.
Panel A: Ghrelin levels. Panel B: Leptin Levels.
