Kowada A, Asaka M. Economic and health impacts of Helicobacter pylori eradication strategy for the treatment of peptic ulcer disease: A cost-effectiveness analysis. Helicobacter 2022; 27:e12886. [PMID: 35343031 PMCID: PMC9286595 DOI: 10.1111/hel.12886] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/29/2022] [Revised: 02/27/2022] [Accepted: 02/28/2022] [Indexed: 12/13/2022]
Abstract
BACKGROUND Most 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 METHODS We 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. RESULTS In 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. CONCLUSIONS H. 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.

Abstract
AIM This study aimed to analyze the cost-effectiveness of two routine therapeutic methods for H. pylori eradication in Iran. BACKGROUND Because of the importance of Helicobacter pylori (H. pylori) eradication on gastric cancer prevalence and costs, an economic analysis of the eradication methods is essential for health systems. METHODS This cross-sectional study was conducted on 7,496 participants with positive Hepadnaviridae (HPsAg) test results for H. pylori; 6,163 of them were treated with furazolidone (group A), and 1,333 participants were treated with clarithromycin (group B). Data on GP visits, medications, and HPsAg costs as direct costs and absence from work and transportation as indirect costs was collected by researcher-made questionnaire. Indirect costs were calculated based on face-to-face interviews with 365 patients of the Persian Cohort Center. Successful eradication of H. pylori infection (negative HPsAg) was defined as the effectiveness of the interventions. Incremental cost-effectiveness ratio (ICER) was used to compare the overall results. RESULTS The total direct cost of H. pylori for groups A and B were estimated at 13.7 and 5.83 billion IRR, respectively. The highest and lowest percentages of total costs were the cost of diagnostic services and the time cost, respectively. There was a significant difference between the two groups in drug costs (p<0.001). The effect ratio for groups A and B was 85.93% and 96.54%, respectively. Cost per effectiveness was higher for clarithromycin (CE=3,250,170 IRR) than for furazolidone (CE=2,988,488 IRR), and ICER showed that 5.1 Million IRR per participant is needed to eradicate H. pylori. CONCLUSION Based on the results, furazolidone was more cost-effective than clarithromycin for H. pylori treatment. Therefore, due to the high prevalence of H. pylori and the economic conditions of the health system in Iran, furazolidone can be a cost-effective choice between the two conventional treatment methods considering the results of further research and possible side effects.

Abstract
Background: Nonsteroidal anti-inflammatory drugs (NSAIDs) are a class of the most commonly used medicines and proven to be effective for certain disorders. Some people use NSAIDs on daily basis for preventive purpose. But a variety of severe side effects can be induced by NSAIDs. Studies have shown that edible natural ingredients exhibit preventive benefit of gastric ulcer. This paper reviews the efficacy and safety of edible natural ingredients in preventing the development of gastric ulcer induced by NSAIDs in animal models. Methods: A systematic literature search was conducted on PubMed, using the terms “herbal medicines” and “gastric ulcer”, “herbal medicines” and “peptic ulcer”, “food” and “peptic ulcer”, “food” and “gastric ulcer”, “natural ingredient” and “peptic ulcer”, “natural ingredient” and “gastric ulcer”, “alternative medicine” and “peptic ulcer”, “alternative medicine” and “gastric ulcer”, “complementary medicine” and “peptic ulcer”, “complementary medicine” and “gastric ulcer” in papers published in English between January 1, 1960 and January 31, 2016, resulting in a total of 6146 articles containing these terms. After exclusion of studies not related prevention, not in NSAID model or using non-edible natural ingredients, 54 articles were included in this review. Results: Numerous studies have demonstrated that edible natural ingredients exhibit antiulcerogenic benefit in NSAID-induced animal models. The mechanisms by which edible, ingredient-induced anti-ulcerogenic effects include stimulation of mucous cell proliferation, antioxidation, inhibition of gastric acid secretion, as well as inhibition of H (+), K (+)- ATPase activities. Utilization of edible, natural ingredients could be a safe, valuable alternative to prevent the development of NSAID-induced gastric ulcer, particularly for the subjects who are long-term users of NSAIDs.

Abstract
BACKGROUND Over the past few years, the profile of Helicobacter pylori infection has changed in Japan. In particular, the relationship between H. pylori and gastric cancer has been demonstrated more clearly. Accordingly, the committee of the Japanese Society for Helicobacter Research has revised the guidelines for diagnosis and treatment of H. pylori infection in Japan. MATERIALS AND METHODS Four meetings of guidelines preparation committee were held from July 2007 to December 2008. In the new guidelines, recommendations for treatment have been classified into five grades according to the Minds Recommendation Grades, while the level of evidence has been classified into six grades. The Japanese national health insurance system was not taken into consideration when preparing these guidelines. RESULTS Helicobacter pylori eradication therapy achieved a Grade A recommendation, being useful for the treatment of gastric or duodenal ulcer, for the treatment and prevention of H. pylori-associated diseases such as gastric cancer, and for inhibiting the spread of H. pylori infection. Levels of evidence were determined for each disease associated with H. pylori infection. For the diagnosis of H. pylori infection, measurement of H. pylori antigen in the feces was added to the tests not requiring biopsy. One week of proton-pump inhibitor-based triple therapy (including amoxicillin and metronidazole) was recommended as second-line therapy after failure of first-line eradication therapy. CONCLUSION The revised Japanese guidelines for H. pylori are based on scientific evidence and avoid the administrative restraints that applied to earlier versions.

Abstract
BACKGROUND Eradicating Helicobacter pylori markedly reduces ulcer recurrence in patients with peptic ulcer disease (PUD). Many decision analysis studies have concluded that eradicating H. pylori in PUD patients is more cost-effective than maintaining antisecretory therapy. In 1995, we introduced an H. pylori eradication program into a large transportation company that experienced increased incidences of PUD among its employees along with increased medical costs, and we performed trend analysis of the actual medical costs of PUD in this cohort. METHODS In this cohort, there were approximately 8500 employees. H. pylori-positive PUD patients were identified at the annual health check up. The patients received eradication therapy with lansoprazole, amoxicillin, and clarithromycin. After eradication, the patients were followed up by a yearly health check up. The annual number of patients who received eradication was recorded, and the annual direct medical costs of PUD therapy were analyzed. RESULTS A total of 440 H. pylori-positive PUD patients received eradication therapy in a 7-year period. Based on an intention-to-treat analysis, the eradication rate was 84.5% (372 of 440). The largest number of patients who received eradication therapy was found in 1995 (n = 115), and from 1995 to 2001 this number decreased yearly by 12.5 (95% confidence interval (CI): 5 to 20). Between 1989 and 1995, the annual medical costs arising of PUD therapy increased by yen2.25 million (95% CI: 1.19 to 3.31) per year, being highest ( yen22.75 million) in 1995. Between 1995 and 2001, the costs decreased by yen3.88 million (95% CI: 3.16 to 4.59) per year. The cost in 2001 was 5.7% of the cost in 1995. The eradication program was terminated in 2001 because the prevalence of PUD diminished markedly, and the associated medical costs decreased as well. CONCLUSIONS H. pylori eradication could reduce the number of PUD patients and associated medical costs in the workplace setting.

Abstract
We conducted a comprehensive evaluation of tele-palliative care by triangulation method. This consisted of qualitative analyses of 2 patients and then performing quantitative analysis of a simulated model for tele-palliative care based on that experience. Semistructured interviews with 2 patients were conducted for qualitative analysis. The recorded conversations were analyzed using traditional categorization and coding techniques, looking for patterns and themes both within and across the interviews. A state-transition process was modeled using a Markov model to compare the costs for three different options for patients requiring palliative care: admission to the palliative care unit, home care only (8 physician visits), and tele-palliative care. The cost data were mainly derived from the reimbursement scale of the Japanese Health Insurance System. Sensitivity analysis was used to assess the influence of particular conditions or costs. The qualitative assessment identified some positive concepts, such as "expectation," "convenience," "reliance," and "communication." In the cost analysis, the reference case yielded the annual costs as follows: (1) costs for admission to the palliative care unit were 1,137,000 dollars; (2) costs for home care were 521,000 dollars; and (3) costs for telepalliative care were 478,000 dollars. One-way sensitivity analyses showed that home care was the most cost-saving strategy if the care was continued for more than 4 months or the number of physician visits during tele-palliative care could be reduced to less than 6 physician visits per month. The important issues in reducing the cost of tele-palliative care were (1) having adequate patient numbers, (2) reducing the number of physicians' visits, and (3) offsetting the costs of telemedicine against cost savings to the system to sustain the program. In addition, the qualitative analysis demonstrated patients positive views of tele-palliative care.

Abstract
AIM: The eradication rate of Helicobacter pylori (H pylori) shows variation among countries and regimens of treatment. We aimed to study the eradication rates of different regimens in our region and some factors affecting the rate of eradication.
METHODS: One hundred and sixty-four H pylori positive patients (68 males, 96 females; mean age: 48 ± 12 years) with duodenal or gastric ulcer without a smoking history were included in the study. The patients were divided into three groups according to the treatment regimens. Omeprazole 20 mg, clarithromycin 500 mg, amoxicillin 1 g were given twice daily for 1 week (Group I) and 2 weeks (Group II). Patients in Group III received bismuth subsitrate 300 mg, tetracyline 500 mg and metronidazole 500 mg four times daily in addition to Omeprazole 20 mg twice daily. Two biopsies each before and after treatment were obtained from antrum and corpus, and histopathologically evaluated. Eradication was assumed to be successful if no H pylorus was detected from four biopsy specimens taken after treatment. The effects of factors like age, sex, H pylori density on antrum and corpus before treatment, the total H pylori density, and the inflammation scores on the rate of H pylori eradication were evaluated.
RESULTS: The overall eradication rate was 42%. The rates in groups II and III were statistically higher than that in group I (P < 0.05). The rates of eradication were 24.5%, 40.7% and 61.5% in groups I, II and III, respectively. The eradication rate was negatively related to either corpus H pylori density or total H pylori density (P < 0.05). The median age was older in the group in which the eradication failed in comparison to that with successful eradication (55 yr vs 39 yr, P < 0.001). No correlation between sex and H pylori eradication was found.
CONCLUSION: 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.
