The findings provide strong evidence that H. pylori infection is associated with cobalamin deficiency, and show that this is true even in patients with non-ulcer dyspepsia and minimal or no gastric atrophy.

Our rates of eradication were significantly lower when compared to those reported in literature. We believe that advanced age and high H pylori density are negative predictive factors for the rate of H pylori eradication.

Objective: Helicobacter pylori is the major etiologic agent for chronic active gastritis, and it also plays a crucial role in gastric and duodenal ulcer disease, as well as in gastric carcinoma. H. pylori infection has been shown to decrease plasma somatostatin (SST) and increase plasma gastrin concentrations. Ghrelin is a recently discovered peptide produced mostly in the stomach of rodents and humans and is secreted into the bloodstream. There is no data in the literature about the relationship between H. pylori and ghrelin. Design: Thirty-nine age-and BMI-matched H. pylori infection positive and negative women, from whom biopsy specimens were taken during gastric endoscopy, were included in the study. Methods: Total ghrelin was measured by enzyme immunoassay (EIA) in Medistek. All samples were measured in duplicate and averaged; results differing by more than 20% were re-assayed. Two biopsy specimens from antrum, corpus and fundus were obtained. Results: Fifteen of the subjects were H. pylori negative and 24 were H. pylori positive. Age, BMI, lipid profile and insulin sensitivity indices of the groups were similar. Plasma ghrelin levels ð375:92^7:10 vs 370:00^4:14 pmol=l; P . 0:05Þ of H. pylori negative and positive groups did not differ significantly. Conclusion: H. pylori has no effect on plasma ghrelin concentration.

Administration of OPS causes a significant rise in serum phosphate, even in patients with normal CCR. The elevation is significantly greater in elderly patients. Administration of OPS can be considered safe for young and middle-aged patients with normal renal function; however, it should be used with caution in elderly patients, even in those with normal CCR and serum creatinine values.
