The Association of Helicobacter pylori Eradication with the Occurrences of Chronic Kidney Diseases in Patients with Peptic Ulcer Diseases.

ABSTRACT: The association of Helicobacter pylori eradication with the occurrence of renal dysfunction in patients with peptic ulcer diseases is still unclear. This study aimed to clarify the relevance of H. pylori eradication to the occurrence of chronic kidney diseases in patients with peptic ulcer diseases. Data that were available from 2000-2011 were extracted from the National Health Insurance Research Database in Taiwan, and all patients with peptic ulcer diseases (n = 208 196) were screened for eligibility. We divided randomly selected patients into an H. pylori eradication cohort (cohort A, n = 3593) and matched them by age and sex to a without H. pylori eradication cohort (cohort B, n = 3593). Subgroup analysis was further performed for H. pylori eradication within ? 90 days of the diagnosis date (early eradication, n = 2837) and within 91-365 days (non-early eradication, n = 756). Cox proportional hazards regression analysis was used to estimate the association of H. pylori eradication with the risk of developing chronic kidney diseases and mortality. We observed that there were more patients suffering from chronic kidney disease in cohort B than in the early eradication subgroup of cohort A (8.49% vs. 6.70%, respectively, p = 0.0075); the mortality rate was also higher in cohort B (4.76% vs. 3.70%, respectively, p = 0.0376). Old age, pulmonary disease, connective tissue disorders, and diabetes were risk factors for chronic kidney diseases but early H. pylori eradication was a protective factor against chronic kidney diseases (hazard ratio: 0.68, 95% confidence interval: 0.52-0.88, p = 0.0030), and death (hazard ratio: 0.69, 95% confidence interval: 0.49-0.96, p = 0.0297). In conclusion, our findings have important implications suggesting that early H. pylori eradication is mandatory since it is associated with a protective role against the occurrence of chronic kidney diseases.

Project description:BackgroundMost peptic ulcer cases are associated with Helicobacter pylori (H. pylori) infection or the use of nonsteroidal anti-inflammatory drugs (NSAIDs). H. pylori eradication therapy is recommended for the treatment of H. pylori-positive peptic ulcers. We aimed to assess and validate the cumulative economic and health effects of H. pylori eradication strategy for the treatment of peptic ulcers compared with PPI therapy strategy.Materials and methodsWe developed a cohort state-transition model for H. pylori eradication strategy and PPI therapy strategy over a lifetime horizon from a healthcare payer perspective. We targeted two hypothetical cohorts of H. pylori-positive patients with gastric and duodenal ulcers aged 20, 30, 40, 50, 60, 70, and 80. The main outcomes were costs, quality-adjusted life-years (QALYs), life expectancy life-years (LYs), incremental cost-effectiveness ratios, ulcer recurrence cases, and ulcer-associated deaths. One-way and probabilistic sensitivity analyses were conducted to assess the impact of uncertainty.ResultsIn the base-case analysis, H. pylori eradication strategy was less costly with greater benefits than PPI therapy strategy in all age groups. Cost-effectiveness was not sensitive to any variables in all age groups. Sensitivity analyses showed strong robustness of the results. From 2000 to 2020, H. pylori eradication strategy saved US$14.07 billion over a lifetime, increased 8.65 million QALYs and 1.23 million LYs over a lifetime, and prevented 551,298 ulcer recurrence cases and 59,465 ulcer-associated deaths, compared with PPI therapy strategy.ConclusionsH. pylori eradication strategy not only has contributed significantly to preventing ulcer recurrence and reducing ulcer-associated deaths but also has resulted in great cost savings. All over the world, H. pylori eradication strategy is likely to have yielded a comparable magnitude of economic and health benefits, depending on the epidemiology of H. pylori-related peptic ulcers and the healthcare environment in each country.

Project description:The evidences on the association of Helicobacter pylori (H. pylori) to coronary heart diseases (CHD) are conflicting. In order to answer this important but yet unanswered clinical health issue, a large cohort study such as big data from the Taiwan National Health Insurance Research Database should be more convincing. Therefore, we aimed to make use of these big data source to analyze and clarify the relevance of H. pylori eradication and CHD risks. We looked through a total of 208196 patients with peptic ulcer diseases (PUD) from the years of 2000 to 2011. First, 3713 patients who received H. pylori eradication within 365 days of the index date were defined as the group A. We randomly selected the same number of patients as cohort A from 55249 non-eradication patients to be the comparison group B using propensity scores (including age, gender and comorbidity) so that we could control the confounding variables of CHD and mortality. Importantly, we perform sensitivity analysis for the time-dependent association between H. pylori eradication and risk of CHD, interactions between patient demographic characteristics and therapy by age (? or < 65 years old). The results showed that a trend of decreased association of CHD in patients with early eradication was observed compared to those without eradication (2.58% vs. 3.35%, p = 0.0905). The mortality rate was lower in early eradication subgroup compared to cohort B (2.86% vs. 4.43%, p = 0.0033). Interestingly, there was also significant difference observed in composite end-points for CHD and death in the early eradication subgroup (0.16% vs.0.57%, p = 0.0133). Further, the cumulative CHD rate was significantly lower in younger patients (< 65 years old) with H. pylori eradication therapy started < 1 year compared to those patients without eradication at all (p = 0.0384); the treatment did not appear to have an effect in older patients (? 65 years old) (p = 0.1963). Multivariate analysis showed that hypertension and renal diseases were risk factors for CHD in patients without eradication whilst younger age (< 65 years old) initiated with H. pylori therapy was a protective factor. In conclusion, the trend of decrease in CHD occurrence after early H. pylori eradication in addition to the significant decrease in composite end points for CHD and death, the significantly lower cumulative CHD rate in younger patients < 65 years old with H. pylori treated within 365 days suggested that there was positive association between H. pylori eradication and CHD.
