Abstract
An extensive evaluation of disease occurrence after statin use based on a "hypothesis-free" approach remains scarce. To examine the effect of statin use on the potential risk of developing diseases, a propensity score-matched cohort study was executed using data from the National Sample Cohort in South Korea. A total of 7847 statin users and 39,235 nonstatin users were included in the final analysis. The period of statin use was defined as our main time-dependent exposure and was divided into three periods: current, recent, and past. The main outcomes were defined as new-onset diseases with ≥100 events based on the International Statistical Classification of Diseases, 10th Revision. We calculated the adjusted hazard ratios and 95% confidence intervals (CIs) using Cox regression. We found that statin use significantly increased the risk of developing iron deficiency anemia up to 5.04 times (95% CI, 2.11 to 12.03). Therefore, the iron levels of patients using statins should be monitored carefully.

Abstract
Atherosclerosis-related coronary artery disease (CAD) is the leading cause of mortality and morbidity worldwide. This requires effective primary and secondary prevention in reducing the complications related to CAD; the regression or stabilization of the pathology remains the mainstay of treatment. Statins have proved to be the most effective treatment in reducing adverse effects, but there are limitations related to the administration and achievement of effective doses as well as side effects due to the lack of target-related molecular specificity. The implemented technological steps are polymers and nanoparticles for the administration of statins, as it has been seen how the conjugation of drug delivery systems (DDSs) with statins increases bioavailability by circumventing the hepatic-renal filter and increases the related target specificity, enhancing their action and decreasing side effects. Reduction of endothelial dysfunction, reduced intimal hyperplasia, reduced ischemia-reperfusion injury, cardiac regeneration, positive remodeling in the extracellular matrix, reduced neointimal growth, and increased reendothelialization are all drug-related effects of statins enhanced by binding with DDSs. Recent preclinical studies demonstrate how the effect of statins stimulates the differentiation of endogenous cardiac stem cells. Poly-lactic-co-glycolic acid (PLGA) seems to be the most promising DDS as it succeeds more than the others in enhancing the effect of the bound drug. This review intends to summarize the current evidence on polymers and nanoparticles for statin delivery in the field of cardiovascular disease, trying to shed light on this topic and identify new avenues for future studies.

Abstract
BACKGROUND The baseline incidence of the adverse events of statin therapy varies between countries. Notably, Chinese patients seem more susceptible to myopathy induced by simvastatin. OBJECTIVES This research studies the adverse drug reactions (ADRs) of statin therapy in China by analysing trial-based data from the Anti-hyperlipidaemic Drug Database built by the China National Medical Products Administration Information Centre. METHODS All clinical trials involving statin therapy (including simvastatin, atorvastatin, fluvastatin, lovastatin, pravastatin and rosuvastatin) in China from 1989 to 2019 were screened. In total, 569 clinical studies with 37 828 patients were selected from 2650 clinical trials in the database. RESULTS Among the reported cases with ADRs (2822/37 828; 7.460%), gastrointestinal symptoms were the most common (1491/37 828; 3.942%), followed by liver disease (486/37 828; 1.285%), muscle symptoms (444/37 828; 1.174%) and neurological symptoms (247/37 828; 0.653%). Pravastatin (231/1988; 11.620%) caused the most common gastrointestinal side effects, followed by fluvastatin (333/3094; 10.763%). The least likely to cause gastrointestinal irritation was rosuvastatin (82/1846; 4.442%). CONCLUSION In Chinese clinical trials, gastrointestinal symptoms were the most common ADR of statin use for hyperlipidaemia and other cardiovascular diseases.

Abstract
BACKGROUND Gastrointestinal bleeding (GIB) is widespread in patients with impaired renal function. Whether angiotensin-converting enzyme inhibitors/angiotensin II receptor blockers (ACEi/ARBs) potentially take a crucial role in avoiding GIB incidence among peritoneal dialysis (PD) patients is unknown. METHODS Overall, 734 PD patients were enrolled after using propensity score matching. Kaplan-Meier analysis and COX regression were used to explore correlation between ACEi/ARBs and GIB. Competitive risk model was aimed to identify whether other events were confounding factors. Forest plot was applied to assess the influence of ACEI/ARBs on GIB incidence in different groups. RESULTS During 8-year follow-up, 89 (12.13%) cases of GIB were recorded. Kaplan-Meier analysis revealed that the incidence of GIB among patients taking ACEi/ARBs was lower than those subjects who had not (log rank = 6.442, P = 0.011). After adjusted different confounding factors, administration of ACEi/ARBs was associated with lowered GIB incidence (adjusted HR = 0.49, 95% CI 0.32-0.77, P = 0.002). In competitive risk model, considering of other events, the incidence of GIB in two groups was still statistically significant (P = 0.010). Subgroup analysis showed ACEi/ARBs taking impeded GIB in the ≥ 60 age group (HR = 0.52, 95% CI 0.28-0.98, P = 0.040). CONCLUSION PD patients who were submitted to ACEi/ARBs inclined to have a lower risk for GIB. In this regard, ACEi/ARBs offered a promising choice to GIB.

Abstract
OBJECTIVE This study aimed to comprehensively evaluate the risk of gastrointestinal bleeding (GIB) with statin monotherapy or with concomitant warfarin use. DATA SOURCES PubMed, Web of Science, and EMBASE (via Scopus) were searched for observational studies that reported the risk of GIB in adults on statin therapy or with concomitant warfarin use until August 28, 2021. STUDY SELECTION AND DATA EXTRACTION Observational studies evaluating the risk of GIB in adults (age >18 years) on statin medication or concomitant use with warfarin were included. DATA SYNTHESIS In all, 14 studies with a total of 5 235 123 participants, reporting 48 677 GIB events (43 734 from statin users and 4943 from users of statin combined with warfarin), were included in the analyses. The pooled analysis revealed no difference in the risk of GIB with statin monotherapy (relative risk [RR]: 0.65; 95% CI: 0.42-1.02) or concomitant statin + warfarin use (RR: 0.97; 95% CI: 0.91-1.02). Prior use of statin was not associated with GIB risk (RR: 0.88; 95% CI: 0.63-1.22), whereas a shorter duration of statin use (<5 years) was associated with a lower risk of GIB (RR: 0.42; 95% CI: 0.18-0.97). RELEVANCE TO PATIENT CARE AND CLINICAL PRACTICE This analysis provides strong evidence on the association between statin use (with/without warfarin) and risk of GIB. CONCLUSION Statin alone or combined with warfarin was not significantly associated with either an increased or decreased risk of GIB. The GIB risk was significantly lower when statins were used for a short duration (<5 years). The putative relationship between statins and GIB in warfarin users warrant further investigation.

The risk of major bleeding event in patients with chronic kidney disease on pentoxifylline treatment. Sci Rep 2021; 11:13521. [PMID: 34188087 PMCID: PMC8241975 DOI: 10.1038/s41598-021-92753-4] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2021] [Accepted: 06/07/2021] [Indexed: 12/17/2022] Open
Abstract
Patients with chronic kidney diseases (CKD) are often treated with antiplatelets due to aberrant haemostasis. This study aimed to evaluate the bleeding risk with CKD patients undergoing pentoxifylline (PTX) treatment with/without aspirin. In this retrospective study, we used Taiwan’s National Health Insurance Research Database to identify PTX treated CKD patients. Patients undergoing PTX treatment after CKD diagnosis were PTX group. A 1:4 age, sex and aspirin used condition matched CKD patients non-using PTX were identified as controls. The outcome was major bleeding event (MBE: intracranial haemorrhage (ICH) and gastrointestinal tract bleeding) during 2-year follow-up period. Risk factors were estimated using Cox regression for overall and stratified analysis. The PTX group had higher MBE risk than controls (hazard ratio (HR) 1.19; 95% confidence interval (CI) 0.94–1.50). In stratified analysis, hyperlipidaemia was a significant risk factor (HR: 1.42; 95% CI 1.01–2.01) of MBE. A daily PTX dose larger than 800 mg, females, non-regular aspirin usage, and ischaemic stroke were risk factors for MBE in PTX group. When prescribing PTX in CKD patients, bleeding should be closely monitored, especially in those with daily dose more than 800 mg, aspirin users, and with a history of ischaemic stroke.

Abstract
BACKGROUND/OBJECTIVES Peptic ulcer disease (PUD) is one of the most common gastrointestinal disorders worldwide. Recent epidemiologic studies have suggested the protective effect of statins against the development of PUD although the results were inconsistent. This systematic review and meta-analysis was conducted with the aim to summarise all available data. METHODS A literature review was performed using MEDLINE and EMBASE database from inception to December 2017. Cohort, case-control and cross-sectional studies that compared the risk of PUD among statins users versus non-users were included. Pooled odds ratio (OR) and 95% confidence interval (CI) were calculated using a random-effect, generic inverse variance method. RESULTS A total of 3 studies (1 case-control and 2 retrospective cohort studies) met the eligibility criteria and were included in this meta-analysis. The risk of PUD was numerically lower among statins-users compared with non-users with the pooled OR of 0.89. However, the result did not achieve statistical significance with 95% CI of 0.67-1.18. The between-study statistical heterogeneity was high (I2 = 80%). CONCLUSIONS This systematic review and meta-analysis found that the risk of PUD was numerically lower among statin users. However, the results did not reach statistical significance. More studies are still required to further characterise this potential protective effect.

Abstract
BACKGROUND The US Food and Drug Administration's Sentinel System was established to monitor safety of regulated medical products. Sentinel investigators identified known associations between drugs and adverse events to test reusable analytic tools developed for Sentinel. This test case used a comparator with a different indication. OBJECTIVE We tested the ability of Sentinel's reusable analytic tools to identify the known association between warfarin and gastrointestinal bleeding (GIB). Statins, expected to have no effect on GIB, were the comparator. We further explored the impact of analytic features, including matching ratio and stratifying Cox regression analyses, on matched pairs. METHODS This evaluation included data from 14 Sentinel Data Partners. New users of warfarin and statins, aged 18 years and older, who had not received other anticoagulants or had recent GIB were matched on propensity score using 1:1 and 1:n variable ratio matching, matching statin users with warfarin users to estimate the average treatment effect in warfarin-treated patients. We compared the risk of GIB using Cox proportional hazards regression, following patients for the duration of their observed continuous treatment or until a GIB. For the 1:1 matched cohort, we conducted analyses with and without stratification on matched pair. The variable ratio matched cohort analysis was stratified on the matched set. RESULTS We identified 141,398 new users of warfarin and 2,275,694 new users of statins. In analyses stratified on matched pair/set, the hazard ratios (HR) for GIB in warfarin users compared with statin users were 2.78 (95% confidence interval [CI] 2.36-3.28) in the 1:1 matched cohort and 3.10 (95% CI 2.76-3.49) in the variable ratio matched cohort. The HR was lower in the analysis of the 1:1 matched cohort not stratified by matched pair (2.22, 95% CI 1.97-2.49), and highest early in treatment. Follow-up for warfarin users tended to be shorter than for statin users. CONCLUSIONS This study identified the expected GIB risk with warfarin compared with statins using an analytic tool developed for Sentinel. Our findings suggest that comparators with different indications may be useful in surveillance in select circumstances. Finally, in the presence of differential censoring, stratification by matched pair may reduce the potential for bias in Cox regression analyses.

Abstract
BACKGROUND Nearly 70% of Americans with cardiovascular disease use statins, which have documented bleeding effects independent of their cholesterol-lowering activities. However, the literature is conflicting regarding the association between statin use and gastrointestinal hemorrhage. OBJECTIVES The aim of this study was to investigate the risk of gastrointestinal hemorrhage in statin users. METHODS In this retrospective cohort study, data from the Truven Health MarketScan® Research Database (2009-2015) were used to investigate the risk of gastrointestinal hemorrhage amongst statin users aged 30-65 years at the initial prescription claim. Statin users and a group of negative controls (i.e. other chronic medication users) were followed until first gastrointestinal hemorrhage event (both inpatient and outpatient, as well as restricted to inpatient), and were censored at treatment discontinuation, disenrollment from coverage, or the end of the study period. RESULTS Statin users had an elevated risk of gastrointestinal hemorrhage, which was especially apparent in the first year of treatment (1-year adjusted hazard ratio 1.19; 95% confidence interval (CI) 1.15-1.23). The risk of gastrointestinal hemorrhage leading to hospitalization was even higher (1-year adjusted hazard ratio 1.38; 95% CI 1.30-1.69). High-intensity statin users had a greater rate of gastrointestinal hemorrhage than moderate-intensity users (incidence rates per 1000 subject-years 22.2 (95% CI 21.9-22.8) vs. 21.5 (95% CI 21.3-21.8), respectively). CONCLUSIONS In a population of commercially insured subjects aged 30-65 years, statin users had a higher risk for gastrointestinal hemorrhage than other chronic medication users. These findings are important when treating patients at a high risk for bleeding events.

Abstract
Abstract
Background: The additional benefits of certain frequently used chronic drugs such as statins or aspirin are investigated for their possible effect of influencing various types of cancer, including gastric cancer. The possible role of statins in the occurrence of pre-neoplastic gastric lesions has not been investigated.
Aim: The study aims to determine the influence of chronic statin therapy on premalignant gastric lesions (glandular atrophy, intestinal metaplasia and dysplasia), adjusted with the most important aggressive environmental factors of the gastric mucosa (Helicobacter pylori [H. pylori] infection, low-dose aspirin [acetylsalicylic acid, ASA], biliary reflux, smoking, alcohol consumption).
Method: The study included 566 patients with cardiovascular diseases who underwent an upper endoscopy: 222 patients with chronic statin therapy (atorvastatin 20–80 mg/day or rosuvastatin 5–20 mg/day for at least 6 months) and 344 patients without statin intake. A complete set of biopsies from the gastric antrum and corpus were routinely processed and examined, and demographical, clinical, and pathological variables were recorded.
Results: Active H. pylori infection in gastric biopsies (p = 0.45), biliary reflux (p = 0.74), alcohol consumption (p = 0.43), or prior ulcer disease (p = 0.07; OR: 0.59; 95% CI: 0.33–1.04) were not associated with an increased risk for premalignant lesions, neither in the statin, nor the no-statin group. Smoking was associated with premalignant lesions in both groups (p = 0.01; OR: 2.24; 95% CI: 1.12–4.47; and p = 0.04; OR: 1.72; 95% CI: 1.01–2.94, respectively), while chronic use of ASA had no influence (p = 0.24, respective p = 0.35). In multivariate regression models, chronic treatment with statins had a protective effect (p = 0.006; OR: 0.59; 95% CI: 0.4–0.8), while smoking (p = 0.01; OR: 1.99; 95% CI: 1.17–3.39) and age >50 years (p <0.01, OR: 3.09; 95% CI: 1.84–5.21) were predictors for pre-neoplastic lesions. H. pylori infection, gender, alcohol consumption, biliary reflux, or prior ulcer disease were not associated with premalignant lesions (p >0.05). Conclusions: In the studied population, chronic statin treatment seems to be associated with a decreased risk for premalignant gastric lesions, while age over 50 years and smoking, regardless of gender or ASA consumption, remain the most important risk factors for premalignant gastric lesions.

Abstract
Background Data are lacking on the risk and impact of a serious hemorrhage on the prognosis after ischemic stroke (IS) or transient ischemic attack (TIA). We aimed to estimate the incidence of serious hemorrhage, analyze the impact on mortality, and identify predictors of hemorrhage after discharge from IS or TIA. Methods and findings All patients admitted to Östersund Hospital for an IS or TIA in 2010–2013 were included (n = 1528, mean age: 75.1 years). Serious hemorrhages were identified until 31st December 2015. Incidence rates were calculated. The impact on mortality (stratified by functional level) was determined with Kaplan-Meier analysis. Non-parametric estimation under the assumption of competing risk was performed to assess the cumulative incidence and predictors of serious hemorrhages. The incidence rates of serious (n = 113) and intracranial hemorrhages (n = 45) after discharge from IS and TIA were 2.48% and 0.96% per year at risk, respectively. Patients with modified Rankin Scale (mRS) scores of 3–5 exhibited 58.9% mortality during follow-up and those with mRS scores of 0–2 exhibited 18.4% mortality. A serious hemorrhage did not affect mortality in patients with impaired functional status, but it increased the risk of death in patients with mRS scores of 0–2. Hypertension was associated with increased risk of serious hemorrhage. Conclusions We found that, after discharge from an IS or TIA, serious hemorrhages were fairly common. Impairments in function were associated with high mortality, but serious hemorrhages only increased the risk of mortality in patients with no or slight disability. Improved hypertension treatment may decrease the risk of serious hemorrhage, but in patients with low functional status, poor survival makes secondary prevention challenging.

Use of prescription drugs and risk of postoperative red blood cell transfusion in breast cancer patients: a Danish population-based cohort study. Breast Cancer Res 2017; 19:135. [PMID: 29273074 PMCID: PMC5741918 DOI: 10.1186/s13058-017-0926-2] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2017] [Accepted: 12/05/2017] [Indexed: 01/28/2023] Open
Abstract
BACKGROUND Several frequently used prescription drugs may affect bleeding risk. We investigated use of aspirin, nonsteroidal anti-inflammatory drugs (NSAIDs), selective serotonin reuptake inhibitors (SSRIs), and statins and risk of postoperative red blood cell transfusion in breast cancer patients. METHODS Using Danish population-based registries, we identified a cohort of women who underwent surgery for primary breast cancer (n = 22,238) during 2005-2012 and ascertained their use of aspirin, NSAIDs, SSRIs, and statins. For each drug, patients were categorized as users if they filled ≥1 prescription in the 60 days prior to surgery. We calculated the 14-day risk of red blood cell transfusion and relative risks (RRs) with 95% confidence intervals (CIs), comparing users with nonusers for each drug and adjusting for age, cancer stage, and Charlson Comorbidity Index score. RESULTS In our cohort, 1385 (6.2%) women were aspirin users, 1794 (8.0%) were NSAID users, 1110 (4.9%) were SSRI users, and 2053 (9.1%) were statin users. The overall risk of red blood cell transfusion was 1.3%. The 14-day risk of RBC transfusion was 3.5% among aspirin users versus 1.1% among aspirin nonusers (adjusted RR = 1.9, 95% CI: 1.4-2.7), and 1.8% among SSRI users versus 1.2% among SSRI nonusers (adjusted RR = 1.2, 95% CI: 0.7-1.9). Red blood cell transfusion risk was increased among NSAID users, but not in a sensitivity analysis with a 30-day exposure window. Red blood cell transfusion risk was not increased among SSRI and statin users. CONCLUSIONS Primary breast cancer surgery confers a low risk of RBC transfusion. Still, use of aspirin and possibly NSAIDs, but not SSRIs and statins, is associated with increased red blood cell transfusion. This increased risk is not explained by differences in age, stage, or comorbidity level.

Abstract
Several studies have reported constipation, abdominal pain, or diarrhea as common adverse events for statins. Statins are among the most commonly prescribed medications, and the impact on the prevalence of these conditions was rarely studied as main outcomes. The aim of this study is to determine if statin therapy is associated with constipation, abdominal pain, diarrhea, or colitis. This was a retrospective cohort study using a regional military health care data from October 1, 2003, to March 1, 2012. A propensity score-matched cohort of statin users and nonusers was created based on 82 variables. The primary analysis evaluated the odds ratios of the following diagnoses: constipation, ≥3 encounters for constipation; abdominal pain, ≥3 encounters for abdominal pain; diarrhea, ≥3 encounters for diarrhea; colitis, ≥3 encounters for colitis; and endoscopy of the lower gastrointestinal tract, ≥3 endoscopies of the lower gastrointestinal tract. After propensity score matching of 6342 statin users and 6342 nonusers, there was no statistically significant difference in constipation (OR, 0.96; 95%CI, 0.87-1.05; P = .33), abdominal pain (OR, 0.95; 95%CI, 0.88-1.02; P = .15), or colitis (OR, 1.02; 95%CI, 0.91-1.14; P = .73). However, there was an association between statin therapy and endoscopy of the lower gastrointestinal tract (OR, 1.14; 95%CI, 1.04-1.26; P = .002) and decreased odds of diarrhea (OR, 0.88; 95%CI, 0.80-0.97; P = .01). In this retrospective cohort study, an association between statin therapy and increased likelihood of being diagnosed with lower gastrointestinal conditions could not be demonstrated, contrary to some statins package inserts.

Abstract
BACKGROUND Drug interactions, particularly those involving warfarin, are a major clinical and public health problem. Minimizing serious bleeding caused by anticoagulants is a recent major focus of the United States (US) Department of Health and Human Services. This study quantified the risk of gastrointestinal bleeding (GIB) and intracranial hemorrhage (ICH) among concomitant users of warfarin and individual antihyperlipidemics. METHODS The authors conducted a high-dimensional propensity score-adjusted cohort study of new concomitant users of warfarin and an antihyperlipidemic, among US Medicaid beneficiaries from five states during 1999-2011. Exposure was defined by concomitant use of warfarin plus one of eight antihyperlipidemics. The primary outcome measure was a composite of GIB/ICH within the first 30days of concomitant use. As a secondary outcome measure, GIB/ICH was examined within the first 180days of concomitant use. RESULTS Among 236,691 persons newly-exposed to warfarin and an antihyperlipidemic, the crude incidence of GIB/ICH was 13.2 (95% confidence interval 12.7 to 13.8) per 100person-years. Users were predominantly older, female, and Caucasian. Adjusted hazard ratios (aHRs) for warfarin and individual statins were consistent with no association. Warfarin+gemfibrozil was associated with an 80% increased risk of GIB/ICH within the first month of concomitant use (aHR=1.8, 1.4 to 2.4). Warfarin+fenofibrate was associated with a similar increased risk (aHR=1.8, 1.2 to 2.7), yet with an onset during the second month of concomitant use. CONCLUSIONS Among warfarin-treated persons, the use of fibrates-but not statins-increases the risk of hospital presentation for GIB/ICH.

Abstract
BACKGROUND Gallstone disease is a leading cause of morbidity in Western countries and carries a high economic burden. Statin medications decrease hepatic cholesterol biosynthesis and may, therefore, lower the risk of cholesterol cholelithiasis by reducing the cholesterol concentration in the bile. Population-based evidence, however, is sparse. OBJECTIVE To assess the risk of gallbladder diseases among statin users compared with nonusers in an American patient cohort. METHODS We performed a retrospective cohort study of patients enrolled in the San Antonio Tricare health system using data between October 2003 and March 2012. We defined 2 groups: statin users (use for 90 days or greater) and nonusers (no prior statin). A propensity score based on 82 variables was generated to match statin users and nonusers 1:1. Outcomes included incidence of cholelithiasis, biliary tract diseases, and gallbladder procedures. RESULTS A total of 43 438 patients were identified; 13 626 (31.4%) were statin users, and 29 812 (68.6%) were nonusers. We matched 6342 pairs of statin users and nonusers based on propensity score. The odds ratios (ORs) in statin users in comparison to nonusers were similar for cholelithiasis (OR = 0.86; 95% CI = 0.73, 1.02), biliary tract disease (OR = 0.85; 95% CI = 0.67-1.08), and gall bladder procedures (OR = 0.85; 95% CI = 0.69, 1.04). CONCLUSIONS Statin use was not significantly associated with either an increased or decreased risk of cholelithiasis or gallbladder disease.

Abstract
BACKGROUND This study was to determine the association between the use of statins and the occurrence of peptic ulcer diseases (PUD). METHODS Using the National Health Insurance Research Database to conduct a population-based cohort study. We identified 48,562 patients who were newly diagnosed with hyperlipidemia during the period of 1998 to 2011 and who were divided into two groups based on their use of statins. The non-statin cohort (without statin treatment, 24,139 patients) were 1:1 frequency matched with sex, age, year of diagnosis of hyperlipidemia and index-year to the statin cohort (24,423 patients). The relative risk of patients with and without statins treatment on the occurrence of PUD and concomitant use of nonsteroidal anti-inflammatory drugs (NSAIDs) and aspirin were analyzed using the univariable and multivariable Cox proportional hazards regression model. RESULTS The incidence of PUD increased with age in both cohorts and female had a higher occurrence rate than male in both cohorts. Compared with the non-statin cohort, the statin cohort was associated with a significant lower risk of PUD for all age group. The concomitant use of aspirin and/or NSAIDs had higher incidence of PUD than those without in both cohorts. Analyzing the cumulative defined daily dose (DDD) of statins indicated that high-dose groups (≧ 575 DDD) exhibited significantly decreased risk compared with non-statin users. CONCLUSION The results of the present study indicated that statins might be associated with the protection of peptic ulcer in a dose-respondent manner.
