Ethnic variance on long term clinical outcomes of concomitant use of proton pump inhibitors and clopidogrel in patients with stent implantation: A PRISMA-complaint systematic review with meta-analysis.

ABSTRACT:

Background

Pharmacokinetic and pharmacodynamic study showed a lower clopidogrel response when coprescribed with proton pump inhibitors (PPIs). Despite this, PPIs is necessary for patients treated with long term dual antiplatelet therapy (DAPT). Ethnic variance also played a different effect on clopidogrel response. Our study evaluated the effect of concomitant use of DAPT and PPIs and assessed whether ethnic variance exert different effect on clinical outcomes.

Methods

We carefully searched EMBASE, PubMed/Medline databases, and the Cochrane library in April 2019. The primary endpoint was major adverse cardiovascular and cerebrovascular events (MACCE) and individual endpoints reported. We also focused on bleeding events. Studies were excluded if the follow-up were <12?months and patients were not treated with clopidogrel after stent implantation.

Results

A total of 18 studies were included in the systematic review (involving 79,670 patients). No randomized controlled trials (RCTs) were included. PPIs comedication were associated with increased MACCE (odds ratio [OR]?=?1.38; 95% confidence interval [CI]?=?1.28-1.49) while not associated with decreased bleeding risks, such as gastrointestinal bleeding (OR?=?1.05; 95% CI?=?0.53-2.11). PPIs comedication were associated with increased risk for all endpoints among Caucasian population while not with increased risk for MACE (OR?=?1.20; 95% CI?=?0.99-1.39), all-cause death (OR?=?1.24; 95% CI?=?0.74-2.06), cardiac-death (OR?=?1.29; 95% CI?=?0.64-2.57) among Asian population.

Conclusion

PPIs comedication were associated with adverse clinical outcomes, and ethnic variance may exert different effect on clinical outcomes. Subgroup analysis indicated that concomitant use of PPI might be suitable for Asian patients after stent implantation.

Project description:BACKGROUND:Proton-pump inhibitors (PPIs) and clopidogrel are frequently coprescribed, although the benefits and harms of their concurrent use are unclear. OBJECTIVE:To examine the association between concurrent use of PPIs and clopidogrel and the risks for hospitalizations for gastroduodenal bleeding and serious cardiovascular disease. DESIGN:Retrospective cohort study using automated data to identify patients who received clopidogrel between 1999 through 2005 after hospitalization for coronary heart disease. SETTING:Tennessee Medicaid program. PATIENTS:20,596 patients (including 7593 concurrent users of clopidogrel and PPIs) hospitalized for myocardial infarction, coronary artery revascularization, or unstable angina pectoris. MEASUREMENTS:Baseline and follow-up drug use was assessed from automated records of dispensed prescriptions. Primary outcomes were hospitalizations for gastroduodenal bleeding and serious cardiovascular disease (fatal or nonfatal myocardial infarction or sudden cardiac death, stroke, or other cardiovascular death). RESULTS:Pantoprazole and omeprazole accounted for 62% and 9% of concurrent PPI use, respectively. Adjusted incidence of hospitalization for gastroduodenal bleeding in concurrent PPI users was 50% lower than that in nonusers (hazard ratio, 0.50 [95% CI, 0.39 to 0.65]). For patients at highest risk for bleeding, PPI use was associated with an absolute reduction of 28.5 (CI, 11.7 to 36.9) hospitalizations for gastroduodenal bleeding per 1000 person-years. The hazard ratio associated with concurrent PPI use for risk for serious cardiovascular disease was 0.99 (CI, 0.82 to 1.19) for the entire cohort and 1.01 (CI, 0.76 to 1.34) for the subgroup of patients who had percutaneous coronary interventions with stenting during the qualifying hospitalization. LIMITATIONS:Unmeasured confounding and misclassification of exposure (no information on adherence or over-the-counter use of drugs) and end points (not confirmed by medical record review) were possible. Because many patients entered the cohort from hospitals with relatively few cohort members, the analysis relied on the assumption that after adjustment for observed covariates, PPI users from one such hospital could be compared with nonusers from a different hospital. CONCLUSION:In patients with serious coronary heart disease treated with clopidogrel, concurrent PPI use was associated with reduced incidence of hospitalizations for gastroduodenal bleeding. The corresponding point estimate for serious cardiovascular disease was not increased; however, the 95% CI included a clinically important increased risk.
