First-line Helicobacter pylori eradication among patients with chronic liver diseases in Taiwan

Helicobacter pylori eradication in patients with chronic liver diseases (CLDs) and liver cirrhosis is seldom reported. This study aimed to assess the efficacy of 7-day standard triple therapy in patients with CLD including cirrhosis and to investigate the clinical factors influencing the success of eradication. A total of 592 H. pylori-infected patients, who received 7-day standard first-line triple therapy between January 1, 2014, and December 31, 2014, were recruited. Patients were divided into two groups: CLD group (N=136) and non-CLD group (N=456). The eradication rates attained by the CLD and non-CLD groups were 86.0% and 84.2%, respectively, in the per-protocol analysis (p=0.606). The eradication rates of liver cirrhosis and noncirrhosis CLD were 88.5% and 84.3%, respectively (p=0.783). The adverse events were similar between the two groups (8.8% vs. 9.2%, p=0.891). Compliance between the two groups was good (99.3% vs. 99.6%, p=0.670). The univariate analysis showed male sex to be the significant clinical factor in the non-CLD group (p=0.001) and alcohol consumption to be the significant clinical factor influencing H. pylori eradication rate in patients with CLD (p=0.022). Alcohol consumption was the only significant factor influencing H. pylori eradication in multivariate analysis (odds ratio=3.786, p=0.031). The results of this study suggest that H. pylori eradication rates in patients with CLD may be comparable with non-CLD patients. Alcohol consumption was the significant factor influencing H. pylori eradication in patients with CLD.
