Abstract
Numerous evidence has demonstrated that the brain is not an immune-privileged organ but possesses a whole set of lymphatic transport system, which facilitates the drainage of harmful waste from brains to maintain cerebral homeostasis. However, as individuals age, the shrinkage and dysfunction of meningeal and deep cervical lymphatic networks lead to reduced waste outflow and elevated neurotoxic molecules deposition, further inducing aging-associated cognitive decline, which act as one of the pathological mechanisms of Alzheimer's disease. Consequently, recovering the function of meningeal and deep cervical lymph node (dCLNs) networks (as an important part of the brain waste removal system (BWRS)) of aged brains might be a feasible strategy. Herein we showed that the drug brain-entering efficiency was highly related to administration routes (oral, subcutaneous, or dCLN delivery). Besides, by injecting a long-acting lyotropic liquid crystalline implant encapsulating cilostazol (an FDA-approved selective PDE-3 inhibitor) and donepezil hydrochloride (a commonly used symptomatic relief agent to inhibit acetylcholinesterase for Alzheimer's disease) near the deep cervical lymph nodes of aged mice (about 20 months), an increase of lymphatic vessel coverage in the nodes and meninges was observed, along with accelerated drainage of macromolecules from brains. Compared with daily oral delivery of cilostazol and donepezil hydrochloride, a single administered dual drugs-loaded long-acting implants releasing for more than one month not only elevated drug concentrations in brains, improved the clearing efficiency of brain macromolecules, reduced Aβ accumulation, enhanced cognitive functions of the aged mice, but improved patient compliance as well, which provided a clinically accessible therapeutic strategy toward aged Alzheimer's diseases.

Abstract
An 88-year-old woman with atrial fibrillation was admitted to our hospital due to the right hemiplegia and aphasia. MRA shows the left middle cerebral artery M2 occlusion. After intravenous rt-PA, her symptoms improved. She was diagnosed with cardioembolic stroke, and was treated with direct oral anticoagulation therapy. However, she had repeated stereotypical transient right hemiparesis a week after index stroke. Her symptoms were considered capsular warning syndrome (CWS). After cilostazol was administered, no further transient neurological deteriorations occurred. CWS can coexist with acute cardioembolic stroke, and cilostazol was effective.

Abstract
AIMS The study aimed to estimate the cost-effectiveness of CYP2C19 genotype-guided antiplatelet therapy using cilostazol and ticagrelor as an alternative to clopidogrel, compared to conventional antiplatelet therapy with clopidogrel and aspirin. METHODS A 90-day decision tree and 30-year Markov model were employed to assess the costs and quality-adjusted life years (QALYs) of personalized antiplatelet therapy for patients with minor ischemic stroke and high-risk transient ischemic attack, compared to conventional antiplatelet therapy in the Chinese healthcare system. The primary outcome was the incremental cost-effectiveness ratio (ICER). The data sources included clinical trials, published literature, official documents and local prices. One-way sensitivity analysis and probabilistic sensitivity analysis were performed to confirm the robustness of the findings. RESULTS The base-case analysis indicated that the CYP2C19 genotype-guided antiplatelet strategy was cost-effective, and cilostazol group and ticagrelor group yielded an ICER of 3327.40 US dollars (USD)/QALY and 3426.92 USD/QALY, respectively, which were less than threshold. The one-way sensitivity analysis showed the results were robust, where the most sensitive parameter was the disability distribution in the modified Rankin scale 3-5. The probabilistic analysis showed that the CYP2C19 genotype-guided antiplatelet therapy with either cilostazol or ticagrelor was 100% cost-effective under the willingness-to-pay threshold. CONCLUSIONS CYP2C19 genotype-guided antiplatelet therapy using cilostazol and ticagrelor as an alternative to clopidogrel appeared to be more cost-effective than conventional antiplatelet therapy for acute minor ischemic stroke and high-risk transient ischemic attack patients over 30 years in China.

Abstract
BACKGROUND Some patients with ATP1A3 variant-associated polymicrogyria have recurrent transient heart failure. However, effective treatment for the transient cardiac condition remains to be elucidated. CASE REPORT The patient started experiencing focal motor onset seizures in 12 h after birth, revealing bilateral diffuse polymicrogyria. The patient also experienced transient bradycardia (sinus bradycardia) attacks from 15 days old. Echocardiography revealed a reduced ejection fraction; however, no obvious electrocorticogram or electroencephalogram abnormalities were observed during the attacks. Initially, the attacks occurred in clusters daily. They later decreased in frequency, occurring at monthly intervals. Repeated episodes of transient bradycardia attacks and polymicrogyria indicated possible ATP1A3 gene abnormality and genetic testing revealed a novel heterozygous ATP1A3 variant (NM_152296: exon22:c.2977_2982del:p.(Glu993_Ile994del)), which was not found in the patient's parents. Cilostazol was administered at 3 months old for recurrent transient bradycardia attacks. Cilostazol significantly shortened the duration of bradycardia episodes and prolonged the interval between attacks. Cilostazol also effectively treats transient symptomatic bradycardia. CONCLUSION Cilostazol could be a treatment option for recurrent transient bradycardia attacks associated with ATP1A3 gene abnormalities and polymicrogyria.

Abstract
AIM Studies investigating the relationship between pulse pressure (PP) and prognosis in acute ischemic stroke remain limited. Thus, in this study, we aim to determine whether changes in PP in the early phase of ischemic stroke are associated with neurological deterioration or stroke recurrence. METHODS Patients who participated in the Acute Aspirin Plus Cilostazol Dual Therapy for Non-cardiogenic Stroke Patients Within 48 Hours of Symptom Onset (ADS) trial were included in this study. We then divided the patients into four groups (low-low, low-high, high-low, high-high) according to low or high PP both on admission and 24 h after admission. The threshold PP calculated by receiver operating characteristic curve analysis of PP on admission for neurological deterioration within 14 days and recurrent ischemic stroke/transient ischemic attack (TIA) within 3 months was 69 mmHg. RESULTS Neurological deterioration within 14 days was observed in 118 patients (10.6%), whereas recurrent ischemic stroke/TIA within 3 months was noted in 34 patients (3.2%). Among these four groups, both neurological deterioration within 14 days (odds ratio [OR] 2.09, 95% confidence interval [CI] 1.12-3.91; p=0.0209) and recurrent ischemic stroke/TIA within 3 months (OR 4.80; 95% CI 1.62-14.86; p=0.0064) were significantly more frequent in the high-high group than in the low-low group as per the results of our multivariate analysis. In addition, neurological deterioration within 14 days was significantly higher in the high-low group than that in the low-low group (OR 2.70; 95% CI 1.44-5.05; p=0.0019). CONCLUSIONS High PP during the acute phase of ischemic stroke appears to be associated with ischemic stroke recurrence and neurological deterioration, particularly if PP is elevated both on admission and 24 h later after admission.

Abstract
In vivo pharmacokinetic simulations and virtual bioequivalence (BE) evaluation of cilostazol have not yet been described for humans. Here, we successfully developed a physiologically based absorption model to simulate plasma concentrations of cilostazol. In addition, virtual population simulations integrating dissolution of 0.3% sodium dodecyl sulfate water media were executed to evaluate the BE of test and reference formulations. Simulation results show that test and reference formulations were bioequivalent among 28 subjects, but not nine subjects, consistent with clinical studies. The model proved to be an important tool to show potential BE for cilostazol. This finding may facilitate understanding of the potential risks during the development of generic products.

Abstract
BACKGROUND It is unclear whether the s (-) form of esomeprazole (EPZ) has an improved safety profile when compared with its racemic form omeprazole (OPZ). We assessed the potential complications of these optical isomers when combined with cilostazol, clopidogrel, and prasugrel, which are frequently used concomitant medications. METHODS Using two adverse event spontaneous reporting databases, Japanese Adverse Drug Event Report (JADER) and FDA Adverse Event Reporting System (FAERS), adverse event names for hemorrhage, venous/arterial embolization, and thrombus were obtained from the Medical Dictionary for Regulatory Activities. Reported odds ratios were calculated using a 2 × 2 contingency table, and a signal was considered present if the lower limit of the 95% confidence interval was >1. RESULTS In combination with cilostazol, a hemorrhagic signal for OPZ in JADER and arterial emboli and thrombus signals for EPZ were detected in both databases. In combination with clopidogrel, OPZ showed arterial emboli and thrombus signals in JADER and venous/arterial emboli and thrombus signals in FAERS, while EPZ displayed arterial emboli and thrombus signals in FAERS. In contrast, when in combination with prasugrel, there were no adverse event signals in either database. CONCLUSION This study has confirmed using big data, that EPZ, the optical isomer and racemic form of omeprazole, has the beneficial characteristics of being less sensitive to CYP, as was intended by its design.

Abstract
AIM The aim of this study was to investigate the effects of continuous cilostazol use on emergency department (ED) visits, hospitalizations, and vascular outcomes in patients with hemodialysis (HD) with peripheral artery disease (PAD). METHODS This retrospective cohort study recruited 558 adult patients, who had received chronic HD for at least 90 days between January 1, 2008 and December 31, 2012, from the National Health Insurance Research Database. Eligible patients were divided into two groups based on continuing or discontinuing cilostazol treatment. Outcome measures were ED visits, hospitalizations, mortality, and vascular outcomes such as percutaneous transluminal angioplasty, surgical bypass, lower leg amputation, ischemic stroke, hemorrhagic stroke, and cardiovascular events. RESULTS Patients with continuous cilostazol use had significantly higher prevalence of stroke, cancer, vintage, and the use of angiotensin receptor blocker and β-blocker, but significantly lower incidence of ischemic stroke and cardiovascular events, as well as lower mortality, than those without continuous cilostazol use (all p<.05). Continuous cilostazol use was independently associated with lower risk of ED visits, hemorrhagic stroke, and cardiovascular events (adjusted hazard ratios: 0.79, 0.29, and 0.67; 95% confidence intervals: 0.62-0.98, 0.10-0.84, and 0.48-0.96, respectively; all p<.05). Continuous cilostazol use was significantly associated with higher ED visit-free and cardiovascular event-free rates (log-rank test; p<.05). CONCLUSION Continuous treatment of cilostazol in patients with HD with PAD significantly decreases the risk of ED visits, hemorrhagic stroke, and cardiovascular events and improves ED visit-free and cardiovascular event-free rates during long-term follow-up.

Abstract
To reduce pharmacy-related medical expenses, it is necessary to reduce drug costs. One way to achieve this is by increasing the usage rate of generic drugs. The purpose of this study was to identify platelet aggregation inhibitors (PAIs) that contribute to high drug costs and are sold as brand-name drugs in order to increase the usage rate of generic drugs, and to analyze the factors that affect the usage rate of generic drug. We conducted a cross-sectional study based on the National Database of Health Insurance Claims and Specific Health Checkups of Japan Open Data Japan (NODJ) of the Ministry of Health, Labor and Welfare and datasets containing related medical information from official statistical surveys such as the Basic Survey on Wage Structure. Monthly personal income in each prefecture were negatively correlated with outpatient out-of-hospital and outpatient in-hospital prescriptions of the PAIs clopidogrel (75 mg), cilostazol (50 mg), cilostazol (100 mg), and ticlopidine (100 mg), but not between monthly personal income and outpatient out-of-hospital prescription of ticlopidine (100 mg). For outpatient out-of-hospital prescriptions and outpatient in-hospital prescriptions, negative correlation was generally observed between the usage rate of generic drug and monthly personal income, except for ticlopidine (100 mg), which has the lowest price among the brand-name drugs. The usage rate of generic PAIs is negatively correlated with monthly personal income. Promoting the use of generic drugs among high-income earners might be necessary to further increase the usage rate of generic drug.

Abstract
PURPOSE The aim of this study is to examine the potential effect of cilostazol and inflammation on cognitive impairment after stroke in an Asian population. METHODS Forty-five patients with cognitive impairment after ischemic stroke using cilostazol were enrolled as the study group and 45 patients using aspirin or clopidogrel were enrolled as the control group. Neuropsychiatric assessments were administered at the start of the study and after 6 months. Multiple logistic regression analysis was used to estimate the association between the cognitive change and cilostazol use. Macrophage polarization were assessed using flow cytometry in 7 patients. RESULTS There were a significantly higher number of patients with peripheral arterial occlusive disease in the cilostazol group. No significant differences were observed in the cognitive change between the cilostazol and control groups. M1 macrophage subset increment were observed in the patient having a declined cognitive change. CONCLUSION Cilostazol did not make a significant difference in cognitive change after ischemic stroke. M1 macrophage subset increment may indicate post stroke cognitive decline. Due to limited number of subjects, these findings should be examined further in large-scale randomized clinical trials.

Abstract
BACKGROUND We hypothesized that administration of cilostazol may clarify the occult atrial fibrillation (AF) during hospitalization in mild stroke patients, who has no history of AF. METHODS From our prospective non-cardioembolic stroke study, randomized to dual antiplatelet therapy using cilostazol and aspirin or aspirin alone trial (ADS), data on the presence or absence of AF were retrospectively analyzed. In the ADS, during hospitalization, as a routine examination, presence of AF was investigated using electrocardiogram (ECG), ECG monitoring and Holter ECG. Multivariate regression analysis was conducted to evaluate the independent parameters related to the AF. Clinical outcome at 3 months was evaluated using modified Rankin Scale (mRS) score. RESULTS Data on 1194 patients (793 [66%] men; median age [interquartile range] of 69 [61-77] years, National Institutes of Health Stroke Scale score 2 [1-4], onset-to-admission 10.8 [4.7-20.5] hours) were retrospectively analyzed. AF was newly detected in 41 (3%) patients (3 by ECG, 21 by the ECG monitoring and 17 by the Holter ECG) during hospitalization. Patients treated with combined cilostazol and aspirin therapy frequently had the AF than those took aspirin alone (5% vs. 2%, p = .007). Multivariate regression analysis showed that cilostazol administration was one of the independent factors for new-AF (odds ratio 2.672, 95%CI: 1.205-5.927, p = .016). The frequency of mRS 0-1 was 68% in the new-AF group and 67% in the non-AF group (p = 1.000). CONCLUSION Cilostazol therapy may increase the detectability of AF in acute non-cardioembolic stroke, though the new-AF was not related to clinical outcome at 3 months.

Abstract
This study assessed the effect of gender, diabetic status, statin use, smoking, hypertension, cardiac status, and use of cilostazol on the outcome of a supervised exercise program for patients with claudication. Patient risk factors were prospectively recorded in a group of patients who had completed 1 year on a supervised exercise program. In 165 claudicant patients, maximum walking distance increased ( P < .0001) from 67 meters (range, 17-196) to 122 meters (range, 43-409). Quality of life as measured by the Medical Outcome Study Short Form 36 increased ( P < .0001) from a median of 78 (range, 55-110) to 99 (range, 71-154). The improvements in claudication distance, maximal walking distance, and quality of life after the exercise program were not dependent on any of the measured patient factors. Patients referred to exercise programs for claudication are a heterogenous group. Despite this, they benefit equally from such a program.

Abstract
RATIONALE Cerebral microbleeds are lesions that appear as round low signal intensity areas with a diameter of 2-5 mm on gradient echo T2-weighted sequence magnetic resonance imaging. Cerebral microblees are hemorrhages found in the brain parenchyma and they are caused by the extravasation of the blood. Although more patients with ischemic stroke are found to have cerebral microbleeds, only a few studies have evaluated other neurologic abnormalities outside of cognitive dysfunction due to cerebral microbleeds. PATIENT CONCERNS A 73-year-old female patient had only a lacunar infarction with the development of a new microbleed whenever a new neurologic symptom occurred, without the occurrence of acute ischemic stroke. DIAGNOSES A 73-year-old female patient diagnosed symptomatic cerebral microbleeds. INTERVENTIONS Brain magnetic resonance imaging was taken within a few hours of the occurrence of a new symptom and we confirmed increased cerebral microbleeds in the ventral-posterolateral area of the thalamus, consistent with the symptoms. OUTCOMES This case study is meaningful because it proves that repeated occurrences of cerebral microbleeds in a specific area can induce acute ischemic stroke-like symptoms. LESSONS Cerebral microbleeds have been considered to be asymptomatic lesions thus far. However, recent studies have reported the association of cerebral microbleeds with neurological symptoms including cognitive dysfunction. This study confirmed the presence of newly formed cerebral microbleeds through imaging follow-ups whenever a symptom occurred.

Abstract
BACKGROUND Antiplatelet therapy with clopidogrel is recommended to reduce cardiovascular events in patients with peripheral artery disease (PAD); however, clopidogrel efficacy has not been adequately studied in this patient population. Therefore, we aimed to determine the effects of cilostazol therapy on platelet reactivity among PAD patients on clopidogrel. METHODS We performed a cross-sectional pilot study of 46 Puerto Rican patients diagnosed with PAD. The cohort was divided based on use of clopidogrel and cilostazol (n=24) or clopidogrel alone (n=22). Platelet function was measured ex vivo using the VerifyNow P2Y12 assay. Genomic DNA was extracted from peripheral blood samples using the QIAamp DNA Blood Midi Kit, which was subjected to candidate variant genotyping (CYP2C19, ABCB1, PON1 and P2RY12) using TaqMan quantitative polymerase chain reaction assays. All analyses were performed using SAS version 9.4 (SAS Institute). RESULTS Among all enrolled patients, 18 (39%) had high on-treatment platelet reactivity (HTPR). The mean platelet reactivity was 207±53 (range, 78-325) with higher P2Y12 reaction units in the non-cilostazol group, 224±45 vs. 191±55 on the cilostazol group (p=0.03). No significant differences were observed in the clinical or genetic variables between the two groups. A multiple regression analysis determined that history of diabetes mellitus (p=0.03), use of cilostazol (p=0.03) and hematocrit (p=0.02) were independent predictors of platelet reactivity. CONCLUSIONS In Puerto Rican PAD patients on clopidogrel therapy, history of diabetes mellitus, use of cilostazol and hematocrit are independent predictors of platelet reactivity. Adjunctive cilostazol therapy may enhance clopidogrel efficacy among PAD patients with HTPR.

Abstract
BACKGROUND Intermittent claudication (IC) is the classic symptomatic form of peripheral arterial disease affecting an estimated 4.5% of the general population aged 40 years and older. Patients with IC experience limitations in their ambulatory function resulting in functional disability and impaired quality of life (QoL). Endovascular revascularisation has been proposed as an effective treatment for patients with IC and is increasingly performed. OBJECTIVES The main objective of this systematic review is to summarise the (added) effects of endovascular revascularisation on functional performance and QoL in the management of IC. SEARCH METHODS For this review the Cochrane Vascular Information Specialist (CIS) searched the Specialised Register (February 2017) and the Cochrane Central Register of Controlled Trials (CENTRAL; 2017, Issue 1). The CIS also searched trials registries for details of ongoing and unpublished studies. SELECTION CRITERIA Randomised controlled trials (RCTs) comparing endovascular revascularisation (± conservative therapy consisting of supervised exercise or pharmacotherapy) versus no therapy (except advice to exercise) or versus conservative therapy (i.e. supervised exercise or pharmacotherapy) for IC. DATA COLLECTION AND ANALYSIS Two review authors independently selected studies, extracted data, and assessed the methodological quality of studies. Given large variation in the intensity of treadmill protocols to assess walking distances and use of different instruments to assess QoL, we used standardised mean difference (SMD) as treatment effect for continuous outcome measures to allow standardisation of results and calculated the pooled SMD as treatment effect size in meta-analyses. We interpreted pooled SMDs using rules of thumb (< 0.40 = small, 0.40 to 0.70 = moderate, > 0.70 = large effect) according to the Cochrane Handbook for Systematic Reviews of Interventions. We calculated the pooled treatment effect size for dichotomous outcome measures as odds ratio (OR). MAIN RESULTS We identified ten RCTs (1087 participants) assessing the value of endovascular revascularisation in the management of IC. These RCTs compared endovascular revascularisation versus no specific treatment for IC or conservative therapy or a combination therapy of endovascular revascularisation plus conservative therapy versus conservative therapy alone. In the included studies, conservative treatment consisted of supervised exercise or pharmacotherapy with cilostazol 100 mg twice daily. The quality of the evidence ranged from low to high and was downgraded mainly owing to substantial heterogeneity and small sample size.Comparing endovascular revascularisation versus no specific treatment for IC (except advice to exercise) showed a moderate effect on maximum walking distance (MWD) (SMD 0.70, 95% confidence interval (CI) 0.31 to 1.08; 3 studies; 125 participants; moderate-quality evidence) and a large effect on pain-free walking distance (PFWD) (SMD 1.29, 95% CI 0.90 to 1.68; 3 studies; 125 participants; moderate-quality evidence) in favour of endovascular revascularisation. Long-term follow-up in two studies (103 participants) showed no clear differences between groups for MWD (SMD 0.67, 95% CI -0.30 to 1.63; low-quality evidence) and PFWD (SMD 0.69, 95% CI -0.45 to 1.82; low-quality evidence). The number of secondary invasive interventions (OR 0.81, 95% CI 0.12 to 5.28; 2 studies; 118 participants; moderate-quality evidence) was also not different between groups. One study reported no differences in disease-specific QoL after two years.Data from five studies (n = 345) comparing endovascular revascularisation versus supervised exercise showed no clear differences between groups for MWD (SMD -0.42, 95% CI -0.87 to 0.04; moderate-quality evidence) and PFWD (SMD -0.05, 95% CI -0.38 to 0.29; moderate-quality evidence). Similarliy, long-term follow-up in three studies (184 participants) revealed no differences between groups for MWD (SMD -0.02, 95% CI -0.36 to 0.32; moderate-quality evidence) and PFWD (SMD 0.11, 95% CI -0.26 to 0.48; moderate-quality evidence). In addition, high-quality evidence showed no difference between groups in the number of secondary invasive interventions (OR 1.40, 95% CI 0.70 to 2.80; 4 studies; 395 participants) and in disease-specific QoL (SMD 0.18, 95% CI -0.04 to 0.41; 3 studies; 301 participants).Comparing endovascular revascularisation plus supervised exercise versus supervised exercise alone showed no clear differences between groups for MWD (SMD 0.26, 95% CI -0.13 to 0.64; 3 studies; 432 participants; moderate-quality evidence) and PFWD (SMD 0.33, 95% CI -0.26 to 0.93; 2 studies; 305 participants; moderate-quality evidence). Long-term follow-up in one study (106 participants) revealed a large effect on MWD (SMD 1.18, 95% CI 0.65 to 1.70; low-quality evidence) in favour of the combination therapy. Reports indicate that disease-specific QoL was comparable between groups (SMD 0.25, 95% CI -0.05 to 0.56; 2 studies; 330 participants; moderate-quality evidence) and that the number of secondary invasive interventions (OR 0.27, 95% CI 0.13 to 0.55; 3 studies; 457 participants; high-quality evidence) was lower following combination therapy.Two studies comparing endovascular revascularisation plus pharmacotherapy (cilostazol) versus pharmacotherapy alone provided data showing a small effect on MWD (SMD 0.38, 95% CI 0.08 to 0.68; 186 participants; high-quality evidence), a moderate effect on PFWD (SMD 0.63, 95% CI 0.33 to 0.94; 186 participants; high-quality evidence), and a moderate effect on disease-specific QoL (SMD 0.59, 95% CI 0.27 to 0.91; 170 participants; high-quality evidence) in favour of combination therapy. Long-term follow-up in one study (47 participants) revealed a moderate effect on MWD (SMD 0.72, 95% CI 0.09 to 1.36; P = 0.02) in favour of combination therapy and no clear differences in PFWD between groups (SMD 0.54, 95% CI -0.08 to 1.17; P = 0.09). The number of secondary invasive interventions was comparable between groups (OR 1.83, 95% CI 0.49 to 6.83; 199 participants; high-quality evidence). AUTHORS' CONCLUSIONS In the management of patients with IC, endovascular revascularisation does not provide significant benefits compared with supervised exercise alone in terms of improvement in functional performance or QoL. Although the number of studies is small and clinical heterogeneity underlines the need for more homogenous and larger studies, evidence suggests that a synergetic effect may occur when endovascular revascularisation is combined with a conservative therapy of supervised exercise or pharmacotherapy with cilostazol: the combination therapy seems to result in greater improvements in functional performance and in QoL scores than are seen with conservative therapy alone.

Abstract
BACKGROUND The standardization for the clinical use of drug therapy for cerebral infarction (CI) has not yet determined in some aspects. In this paper, we discussed the efficacies of different drug therapies (aspirin, aspirin plus dipyridamole, aspirin plus clopidogrel, aspirin plus warfarin, cilostazol, warfarin, and ticlopidine) for CI. METHODS We searched databases of PubMed and Cochrane Library from the inception to April, 2017, randomized controlled trials (RCTs) met the inclusion and exclusion criteria were enrolled in this study. The network meta-analysis integrated evidences of direct and indirect comparisons to assess odd ratios (OR) and surface under the cumulative ranking curves (SUCRA) value. RESULTS Thirteen eligible RCTs including 7 drug therapies were included into this network meta-analysis. The network meta-analysis results showed that CI patients who received aspirin plus dipyridamole presented lower mortality when compared with those received aspirin plus clopidogrel (OR = 0.46, 95% CI = 0.18-0.99), indicating aspirin plus dipyridamole therapy had better efficacy for CI. As for intracranial hemorrhage (ICH), stroke recurrence, and adverse event (AE) rate, there were no significant differences of efficacy among 7 drug therapies. Besides, SUCRA values demonstrated that in the 7 drug therapies, aspirin plus dipyridamole therapy was more effective than others (mortality: 80.67%; ICH: 76.6%; AE rate: 90.2%). CONCLUSIONS Our findings revealed that aspirin plus dipyridamole therapy might be the optimum one for patients with CI, which could help to improve the survival of CI patients.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Low molecular weight fucoidan (LMWF), extracted from Laminaria japonica Areschoug, is a traditional Chinese medicine, commonly used to alleviate edema, particularly for feet with numbness and pain. AIM OF THE STUDY Diabetic mellitus (DM) patients are at high risk of developing peripheral arterial disease (PAD). Individuals with DM and PAD co-morbidity have a much higher risk of critical limb ischemia. LMWF showed several beneficial effects, such as anti-inflammation, anti-thrombosis, and enhancing revascularization. Therefore, we hypothesized that LMWF might be beneficial to diabetes-induced PAD, and investigated the therapeutic potential of LMWF on diabetic PAD rats. MATERIALS AND METHODS Type 2 diabetic Goto-Kakizaki (GK) rats were made PAD by injection of sodium laurate into femoral artery. LMWF (20, 40 or 80mg/kg/day) or cilostazol (100mg/kg/day) were given to diabetic PAD rats for 4 weeks, respectively. The effects of LMWF on foot ulceration and claudication, plantar blood flow, collateral vessel formation, endothelium morphology, gastrocnemius injury, platelet aggregation, vessel vasodilation, and the expressions of inflammation factors, VEGF, eNOS, and nitric oxide were measured. RESULTS We found that LMWF markedly ameliorated foot ulceration and claudication, and improved the plantar perfusion by reversing hyperreactive platelet aggregation, ameliorating endothelium-dependent vasodilation and revascularization on diabetic PAD rats. In addition, upregulation of several inflammatory factors, such as ICAM-1 and IL-1β in the gastrocnemius muscles of ischemic hindlimb were suppressed by LMWF administration. And eNOS phosphorylation at Ser1177 and NO production were significantly enhanced in LMWF-treated diabetic PAD rats. CONCLUSIONS Taken together, our findings demonstrated that LMWF exhibits therapeutic effect on hindlimb ischemia in type 2 diabetic rats likely through ameliorating endothelium eNOS dysfunction and enhancing revascularization, thus, providing a potential supplementary non-invasive treatment for diabetes-induced PAD.

Abstract
Background Decline in estimated glomerular filtration rate (eGFR) is an important surrogate marker for the assessment of renal function. Addition of a second agent to angiotensin-converting-enzyme inhibitor (ACEI) or angiotensin II receptor blocker (ARB) treatment may improve current therapeutic strategies aimed at suppressing renal disease progression. Objective To determine the effect of cilostazol in combination with ACEI or ARB treatment on the decline in eGFR. Setting A tertiary hospital in Korea. Method In an observational cohort study, we analyzed 5505 patients who were prescribed ACEI or ARB and cilostazol or other antiplatelet agents. Main outcome measure The primary outcome assessed was worsening of renal function defined as a 30% decline in eGFR per year. The secondary outcomes included commencement of dialysis, renal transplantation, death, myocardial infarction, and ischemic stroke. Results Following propensity score matching, eGFR decreased over time in the majority of patients, but the decline was less in patients in the cilostazol treated (CT) group of stage 1-2 category compared to the cilostazol untreated (CU) group (OR 0.80; 95% CI 0.66-0.98). In the subgroup analysis, the strongest effect in slowing eGFR decline was observed in CT patients at a high risk of diabetes (OR 0.782; 95% CI 0.615-0.993) and the elderly (OR 0.693; 95% CI 0.504-0.953) in the stage 1-2 category. No significant increase in cardiovascular risk was observed between the CT and CU groups. Conclusion Treatment with cilostazol plus ACEI or ARB was observed to prevent worsening of renal progression in patients in the stages 1-2.

Abstract
Cilostazol is known to alleviate white matter demyelination due to chronic cerebral hypoperfusion in rodent models, although their pharmacological mechanisms remain unclear. In this study, we investigated the protective effect of cilostazol in relation to gene expression profile. Bilateral common carotid artery stenosis (BCAS) mice were treated with oral administration of cilostazol or placebo starting from a week after the surgery. Demyelination of the cingulum was compared between the 2 groups 2, 6, and 10 weeks after initial drug administration. Also, to examine temporal gene expression change during demyelination, DNA microarray analysis was conducted using samples from the corpus callosum of 2nd and 6th week BCAS mice. For genes that showed more than 2-fold up-regulation, their increase was validated by qPCR. Finally, to determine the effect of cilostazol towards those genes, their expression in the corpus callosum of 6-week placebo-treated and cilostazol-treated BCAS mice was compared by qPCR. Amelioration of myelin loss was observed in cilostazol-treated group, showing significant difference with those observed in placebo group after 10-week treatment. Gene ontology analysis of the 17 up-regulated (FDR<0.01) genes showed that majority of the genes were related to cell development processes. Among the validated genes, expression of Btg2 was significantly promoted in the corpus callosum of BCAS mice by administration of cilostazol. Results of this study suggest that activation of Btg2 may be one of the key pharmacological effects of cilostazol towards the white matter during chronic ischemia.

Abstract
OBJECTIVES hnRNP A2/B1 has been identified as a target antigen of anti-endothelial cell IgA antibody in patients with Behçet's disease (BD). In addition, increased expression of cellular hnRNP A2/B1 is stimulated by Streptococcus sanguinis or the sera from patients with BD. We aimed to investigate the effects of cilostazol on the expression of hnRNP A2/B1 and chemokines in human dermal microvascular endothelial cells (HDMECs). METHODS Expression of hnRNP A2/B1, cytokines, and chemokines in HDMECs was induced by tumour necrosis factor (TNF)-α, interleukin (IL)-1β, and lipopolysaccharide (LPS). HDMECs were treated with cilostazol (10 μM) and the inhibitory effects were evaluated with real-time polymerase chain reaction and immunocytochemistry. RESULTS Expression of hnRNP A2/B1, CXCL1, CXCL2, CXCL8, and IL-1β mRNA was significantly increased in HDMECs treated with all three stimulants. In addition, mRNA expression of hnRNP A2/B1 and inflammatory mediators was significantly inhibited in HDMECs treated with various stimulants with cilostazol pretreatment. Immunocytochemistry demonstrated that cilostazol pretreatment effectively inhibited the stimulant-induced increased expression of hnRNP A2/B1 in the nucleus and cytoplasm of HDMECs. CONCLUSIONS Cilostazol pretreatment can reduce the excessive expression of inflammatory cytokines and chemokines and hnRNP A2/B1 by the BD-related stimulants, including TNF-α, IL-1β, and LPS, in HDMECs. We suggest that cilostazol may have therapeutic efficacy in inhibiting the major inflammatory reaction in the pathogenesis of BD.

Abstract
Whether antiplatelet agents have a preventive effect on cognitive function remains unknown. We examined the potential association between the use of cilostazol, an antiplatelet agent and cyclic adenosine monophosphate phosphodiesterase 3 inhibitor, and the risk of dementia in an Asian population. Patients initiating cilostazol therapy between 1 January 2004 and 31 December 2009 without a prior history of dementia were identified from Taiwan's National Health Insurance database. Participants were stratified by age, sex, comorbidities, and comedication. The outcome of interest was all-cause dementia (ICD-9-CM codes 290.0, 290.4, 294.1, 331.0). Cox regression models were used to estimate the hazard ratio (HR) of dementia. The cumulative cilostazol dosage was stratified by quartile of defined daily doses using no cilostazol use as a reference. A total of 9148 participants 40 years of age or older and free of dementia at baseline were analyzed. Patients using cilostazol (n = 2287) had a significantly decreased risk of incident dementia compared with patients not using the drug [n = 6861; adjusted HR (aHR) 0.75; 95% confidence interval (CI) 0.61-0.92]. Notably, cilostazol use was found to have a dose-dependent association with reduced rate of dementia emergence (p for trend = 0.001). Subgroup analysis identified a decline of dementia in cilostazol users with diagnosed ischemic heart disease (aHR 0.44, 95% CI 0.24-0.83) and cerebral vascular disease (aHR 0.34, 95% CI 0.21-0.54). These observations suggest that cilostazol use may reduce the risk to develop dementia, and a high cumulative dose further decreases the risk of dementia. These findings should be examined further in randomized clinical trials.

Abstract
RATIONALE Caudal epidural injection is one of the conventional treatments of chronic back pain. Even though spinal epidural hematoma after caudal epidural injection is rare but it can cause serious neurologic complication. PATIENT CONCERNS An 83-year-old woman taking cilostazol received caudal epidural steroid injection because of her chronic back pain. Six hours later, she experienced an acute hip pain which worsened with time. DIAGNOSIS Magnetic resonance image showed acute cord compression due to a spinal epidural hematoma at L2-S1 level with concomitant central canal compromise at L2/3, L3/4 level. INTERVENTIONS Emergency decompressive laminectomy and evacuation of the lumbar epidural hematoma were performed. OUTCOMES All of her symptoms were resolved over the 72 hours following surgery. LESSONS Continuous vigilance after caudal epidural injection is important to prevent catastrophic neurologic deterioration with early detection and early treatment.

Abstract
PURPOSE Cilostazol (Pletal), a phosphodiesterase-3 inhibitor, was approved in the United States in 1999 to reduce symptoms of intermittent claudication. Cyclic adenosine monophosphate levels increase from inhibition of phosphodiesterase resulting in anti-platelet, anti-inflammatory, and vasodilatory effects. Diabetes mellitus is a chronic disease that causes endothelial and platelet dysfunction leading to both microvascular and macrovascular complications. This mini-review highlights the emerging evidence suggesting benefits of using cilostazol in treating microvascular complications associated with diabetes mellitus. METHODS A review of literature was conducted using PubMed and Embase databases focusing on cilostazol use in diabetes mellitus. RESULTS Cilostazol demonstrated renoprotective effects in patients with diabetic nephropathy by reducing serum soluble adhesion molecule-1 and monocyte chemoattractant protein-1. Cilostazol's anti-inflammatory actions predictably attenuate glomerular damage from increased leukocyte adherence. Additionally, cilostazol delayed renal dysfunction secondary to type 2 diabetes mellitus as albuminuria was reduced most likely resulting from inhibition of nuclear factor kappa-induced inflammatory and endothelial markers. Cilostazol's anti-inflammatory actions in addition to its vasodilatory actions relieved retinal hypoxia and decreased excessive production of retinal blood vessels suggesting benefit in diabetic retinopathy. Cilostazol did not improve neuropathy symptom scores signifying that it may not be as beneficial in patients with diabetic peripheral neuropathy without diabetic nephropathy or diabetic retinopathy. CONCLUSIONS Cilostazol's pleiotropic effects may be beneficial in patients with type 2 diabetes mellitus and diabetic nephropathy. Additional, larger studies need to be conducted to assess the benefits and risks of using cilostazol as an alternative agent in treating patients with diabetic microvascular complications.

Abstract
BACKGROUND Previous studies have suggested a benefit of cilostazol in addition to standard dual-antiplatelet therapy (DAPT), reducing in-stent late luminal loss and restenosis after percutaneous coronary intervention (PCI) with bare-metal and drug-eluting stent (DES) implantation. However, there is a paucity of intravascular ultrasound (IVUS) assessment of neointimal tissue hyperplasia (NIH) after triple-antiplatelet therapy (TAPT), especially in diabetic patients treated with DES. METHODS This prospective, placebo-controlled trial was conducted in diabetic patients randomized (1:1) to receive either standard DAPT (aspirin and clopidogrel) vs TAPT with cilostazol for a minimum of 12 months after PCI with Endeavor zotarolimus-eluting stent (E-ZES). The primary endpoint was the 9-month comparison of percentage of NIH in both groups. Additionally, we compared in-stent late lumen loss, binary restenosis, major adverse cardiac event (MACE; cardiac death, non-fatal myocardial infarction, and restenosis) rates, and the incidence of vascular/bleeding complications. RESULTS In total, 133 diabetic patients were enrolled (cilostazol cohort = 65 patients) with 56.4% male and mean age of 60.8 years. Overall, the two cohorts were comparable in terms of baseline clinical and angiographic characteristics, except for the reference vessel diameter, which was smaller among patients randomized to cilostazol (2.48 ± 0.46 mm vs 2.69 ± 0.48 mm; P=.01). At 9 months, there was a non-significant trend toward less percentage of NIH obstruction in the TAPT cohort (33.2 ± 8.29% vs 35.1 ± 8.45%; P=.07). However, this finding did not impact angiographic late-lumen loss (0.60 ± 0.46 mm cilostazol group vs 0.64 ± 0.48 mm control group; P=.30) and binary restenosis (9.8% vs 6.8%; P=.99). MACE rate also did not significantly differ between the cohorts (13.8% cilostazol group vs 8.8% control group; P=.81). Of note, the addition of a third antiplatelet agent did not increase vascular and bleeding complications. CONCLUSION In diabetic patients treated with E-ZES, TAPT with cilostazol did not add any significant benefit in terms of NIH suppression or MACE reduction.

Abstract
Restenosis is one of the main complications in patients undergoing coronary or peripheral revascularization procedures and is the leading cause for their long-term failures. Cilostazol is the only pharmacotherapy that showed an adequate efficacy for preventing restenosis in randomized, controlled studies after coronary or peripheral revascularization procedures. The present review sums up the main clinical evidence supporting the use of cilostazol after revascularization interventions, focusing on all its benefits, warnings, and administration schedules.

Abstract
BACKGROUND Cilostazol is a type III phosphodiesterase inhibitor used to treat the symptoms of intermittent claudication. Recent studies have shown that cilostazol decreases ischemia/reperfusion (I/R) injury in several organs. MATERIALS AND METHODS We evaluated the effects of cilostazol in a rat model of liver I/R injury. Thirty male Wistar rats with liver I/R injury were divided into a cilostazol or saline (control) group (n = 15 each). Each rat was orally administered cilostazol or saline for 3 d before I/R injury. Liver I/R injury was induced via 1 h of warm ischemia of the median and left lateral liver lobes, followed by 3 h of reperfusion. The rats were then euthanized. Serum aspartate aminotransferase, alanine aminotransferase, interleukin (IL)-1β, IL-6, and tumor necrosis factor-α levels were measured. The Mann-Whitney U test was used to compare the differences between the treatment groups. Histologic examination was performed on the liver tissues. We also conducted a survival study to confirm the effect of cilostazol on the mortality rate in rats. For the survival study, a liver I/R injury model with an ischemia time of 1.5 h was used, and the rats were observed for 1 wk. RESULTS Serum aspartate aminotransferase, alanine aminotransferase, IL-1β, and IL-6 levels were significantly lower in the cilostazol group than in the saline group. Treatment with cilostazol significantly improved pathological findings associated with liver I/R injury and increased survival rate compared to that in controls. CONCLUSIONS Cilostazol reduced mortality and alleviated the effects of liver I/R injury in Wistar rats.

Abstract
The aim of this study was to determine the effects and underlying mechanism of aripiprazole (APZ) augmentation for cilostazol (CLS)-treated post-ischemic stroke mice that were exposed to chronic mild stress (CMS). Compared to treatment with either APZ or CLS alone, the combined treatment resulted in a greater reduction in depressive behaviors, including anhedonia, despair-like behaviors, and memory impairments. This treatment also significantly reduced atrophic changes in the striatum, cortex, and midbrain of CMS-treated ischemic mice, and inhibited neuronal cell apoptosis, particularly in the striatum and the dentate gyrus of the hippocampus. Greater proliferation of neuronal progenitor cells was also observed in the ipsilateral striatum of the mice receiving combined treatment compared to mice receiving either drug alone. Phosphorylation of the cyclic adenosine monophosphate response element binding protein (CREB) was increased in the striatum, hippocampus, and midbrain of mice receiving combined treatment compared to treatment with either drug alone, particularly in the neurons of the striatum and hippocampus, and dopaminergic neurons of the midbrain. Our results suggest that APZ may augment the antidepressant effects of CLS via co-regulation of the CREB signaling pathway, resulting in the synergistic enhancement of their neuroprotective effects.

Abstract
Objective Some previous studies have found clinical benefit of dual antiplatelet therapy with aspirin and cilostazol for prevention of secondary stroke, but the physiological mechanism involved remains unknown. We aimed to clarify the effects of aspirin/cilostazol therapy on the platelet and endothelial functions of patients with acute noncardioembolic ischemic stroke, in comparison to patients who were treated with aspirin alone. Methods The present randomized prospective pilot study enrolled 24 patients within a week after the onset of noncardioembolic ischemic stroke. The patients were randomly allocated to receive aspirin (100 mg/day) (A group; 11 patients) or cilostazol (200 mg/day) plus aspirin (100 mg/day) (CA group; 13 patients). We measured platelet aggregation, platelet activation, and the thrombomodulin (TM), highly sensitive C-reactive protein (hs-CRP), intercellular adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-1) and von Willebrand (vWF) antigen levels and vWF activity over a 4-week period after enrollment. Results There was no significant difference in the platelet functions of the A and CA groups. However, the platelet aggregation induced by adenosine diphosphate (ADP) was decreased at 2 and 4 weeks (p<0.05) after treatment in comparison to the pre-treatment values in the CA group, but not in the A group. Platelet activation, and the hs-CRP, TM, ICAM-1, VCAM-1 and vWF values did not significantly decrease after treatment in either group. Conclusion Although there were no significant differences in platelet aggregation, platelet activation or the endothelial biomarker levels of the A and CA groups, dual therapy with aspirin and cilostazol inhibited platelet aggregation in comparison to the pre-treatment values, similarly to patients who received aspirin alone. This may suggest the clinical usefulness of dual therapy with aspirin and cilostazol in the treatment of patients with noncardioembolic ischemic stroke.

Abstract
OBJECTIVES To examine the clinical outcome of aneurysmal subarachnoid haemorrhage (aSAH) patients exposed to cerebral vasospasm (CVS)-targeted treatments in a meta-analysis and to evaluate the efficacy of intra-arterial (IA) approaches in patients with severe/refractory vasospasm. METHODS Randomised controlled trials, prospective and retrospective observational studies reporting clinical outcomes of aSAH patients exposed to CVS targeted treatments, published between 2006-2016 were searched using PubMed, EMBASE and the Cochrane Library. The main endpoint was the proportion of unfavourable outcomes, defined as a modified Rankin score of 3-6 at last follow-up. RESULTS Sixty-two studies, including 26 randomised controlled trials, were included (8,976 patients). At last follow-up 2,490 of the 8,976 patients had an unfavourable outcome, including death (random-effect weighted-average, 33.7%; 99% confidence interval [CI], 28.1-39.7%; Q value, 806.0; I 2 = 92.7%). The RR of unfavourable outcome was lower in patients treated with Cilostazol (RR = 0.46; 95% CI, 0.25-0.85; P = 0.001; Q value, 1.5; I 2 = 0); and in refractory CVS patients treated by IA intervention (RR = 0.68; 95% CI, 0.57-0.80; P < 0.0001; number needed to treat with IA intervention, 6.2; 95% CI, 4.3-11.2) when compared with the best available medical treatment. CONCLUSIONS Endovascular treatment may improve the outcome of patients with severe-refractory vasospasm. Further studies are needed to confirm this result. KEY POINTS • 33.7% of patients with cerebral Vasospasm following aneurysmal subarachnoid-hemorrhage have an unfavorable outcome. • Refractory vasospasm patients treated using endovascular interventions have lower relative risk of unfavourable outcome. • Subarachnoid haemorrhage patients with severe vasospasm may benefit from endovascular interventions. • The relative risk of unfavourable outcome is lower in patients treated with Cilostazol.

Abstract
Taxifolin is a potent flavonoid that exerts anti-oxidative effect, and cilostazol increases intracellular cAMP levels by inhibiting phosphodiesterase 3 that shows antiinflammatory actions. BACE1 (β-site APP cleaving enzyme 1) is the rate-limiting enzyme responsible for the β-cleavage of amyloid precursor proteins to Aβ peptides. In this study, endogenous Aβ and C99 accumulation was explored in N2a Swe cells exposed to 1% FBS medium. Increased Aβ and C99 levels were significantly attenuated by taxifolin alone and in combination with cilostazol. Increased phosphorylated JAK2 at Tyr1007/1008 (P-JAK), phosphorylated STAT3 at Tyr 705 (P-STAT3) expressions and increased expressions of BACE1 mRNA and protein in the activated N2a Swe cells were significantly attenuated by taxifolin (10~50 μM), cilostazol (10~50 μM) alone and in combination at minimum concentrations. In these cells, decreased cytosol IκBα expression was elevated, and increased nuclear NF-κB p65 level and nuclear NF-κB p65 DNA binding activity were significantly reduced by taxifolin and cilostazol in a similar manner. Following STAT3 gene (~70% reduction) knockdown in N2a cells, Aβ-induced nuclear NF-κB and BACE1 expressions were not observed. Taxifolin, cilostazol, or resveratrol significantly stimulated SIRT1 protein expression. In SIRT1 gene-silenced (~50%) N2a cells, taxifolin, cilostazol, and resveratrol all failed to suppress Aβ1-42-stimulated P-STAT3 and BACE1 expression. Consequently, taxifolin and cilostazol were found to significantly decrease lipopolysaccharide (1–10 μg/ml)-induced iNOS and COX-2 expressions, and nitrite production in cultured BV-2 microglia cells and to increase N2a cell viability. In conclusion, taxifolin and cilostazol strongly inhibited amyloidogenesis in a synergistic manner by suppressing P-JAK2/P-STAT3-coupled NF-κB-linked BACE1 expression via the up-regulation of SIRT1.

Abstract
Phosphodiesterases (PDEs), which hydrolyze and inactivate 3', 5'-cyclic adenosine monophosphate (cAMP) and 3', 5'-cyclic guanosine monophosphate (cGMP), play an important role in synaptic plasticity that underlies memory. Recently, several PDE inhibitors were assessed for their possible therapeutic efficacy in treating cognitive disorders. Here, we examined how cilostazol, a selective PDE3 inhibitor, affects brain functions in senescence-accelerated mouse prone 8 (SAMP8), an animal model of age-related cognitive impairment. Long-term administration of cilostazol restored the impaired context-dependent conditioned fear memory of SAMP8 to match that in normal aging control substrain SAMR1. Cilostazol also increased the number of cells containing phosphorylated cAMP-responsive element binding protein (CREB), a downstream component of the cAMP pathway. Finally, cilostazol improves blood-brain barrier (BBB) integrity, demonstrated by reduced extravasation of 2-deoxy-2-18F-fluoro-d-glucose and Evans Blue dye in the brains of SAMP8. This improvement in BBB integrity was associated with an increased amount of zona occludens protein 1 (ZO-1) and occludin proteins, components of tight junctions integral to the BBB. The results suggest that long-term administration of cilostazol exerts its beneficial effects on age-related cognitive impairment through a dual mechanism: by enhancing the cAMP system in the brain and by maintaining or improving BBB integrity.

Abstract
AIM To identify risk factors for post-polypectomy bleeding (PPB), focusing on antithrombotic agents.
METHODS This was a case-control study based on medical records at a single center. PPB was defined as bleeding that occurred 6 h to 10 d after colonoscopic polypectomy and required endoscopic hemostasis. As risk factors for PPB, patient-related factors including anticoagulants, antiplatelets and heparin bridge therapy as well as polyp- and procedure-related factors were evaluated. All colonoscopic hot polypectomies, endoscopic mucosal resections and endoscopic submucosal dissections performed between January 2011 and December 2014 were reviewed.
RESULTS PPB occurred in 29 (3.7%) of 788 polypectomies performed during the study period. Antiplatelet or anticoagulant agents were prescribed for 210 (26.6%) patients and were ceased before polypectomy except for aspirin and cilostazol in 19 cases. Bridging therapy using intravenous unfractionated heparin was adopted for 73 patients. The univariate analysis revealed that anticoagulants, heparin bridge, and anticoagulants plus heparin bridge were significantly associated with PPB (P < 0.0001) whereas antiplatelets and antiplatelets plus heparin were not. None of the other factors including age, gender, location, size, shape, number of resected polyps, prophylactic clipping and resection method were correlated with PPB. The multivariate analysis demonstrated that anticoagulants and anticoagulants plus heparin bridge therapy were significant risk factors for PPB (P < 0.0001). Of the 29 PPB cases, 4 required transfusions and none required surgery. A thromboembolic event occurred in a patient who took anticoagulant.
CONCLUSION Patients taking anticoagulants have an increased risk of PPB, even if the anticoagulants are interrupted before polypectomy. Heparin-bridge therapy might be responsible for the increased PPB in patients taking anticoagulants.

Abstract
Vascular imaging techniques, such as catheter angiography, ultrasound, computed tomography (CT), and magnetic resonance (MR), have all undergone unprecedented innovation and incredible technological leaps in the last 10 years. Ultrasound, CT, and MR have progressed in acquisition speed, resolution, and accuracy to the point that they have now supplanted the former mainstay, invasive catheter-based angiography, despite the advent of digitized angiographic image recording. This review explores the advantages and shortcomings of each technique and how they have changed the diagnosis and assessment of the cardiovascular system for endovascular intervention.

Abstract
OBJECTIVES Atrial fibrillation (AF) is the most common sustained arrhythmia in clinical practice. Atrial structural remodeling (ASR), particularly atrial fibrosis, is an important contributor to the AF substrate. This study aimed to investigate the preventive effects of the phosphodiesterase 3 inhibitor cilostazol on ASR and its potential molecular mechanisms in a canine model of rapid atrial pacing (RAP). METHODS Thirty dogs were assigned to sham (Sham), paced/ no treatment (Paced) and paced + cilostazol 5 mg/kg/day (Paced + cilo) groups, with 10 dogs in each group. RAP at 500 beats/min was maintained for 2 weeks, while the Sham group was instrumented without pacing. Cilostazol was provided orally during pacing. Western blotting, RT-PCR and pathology were used to assess ASR. RESULTS Cilostazol attenuated atrial interstitial fibrosis and structural remodeling in canines with RAP. MEK/ERK transduction pathway gene expression was upregulated in the Paced group compared with the Sham group. Cilostazol markedly alleviated these changes in the MEK/ERK pathway. Transforming growth factor-β1 protein expression in the Paced group was significantly higher than in the Sham group (p < 0.01), and was significantly reduced by cilostazol (p < 0.01). CONCLUSIONS Our findings suggest that cilostazol is beneficial for prevention and treatment in atrial tachycardia-induced ASR in a canine model of RAP.

Abstract
In the clinic 60 patients were examined, in whom reconstructive operations on the main arteries were performed for obliterating atherosclerosis (OA) of the lower extremities vessels. Efficacy of impact of Plestazol (in a 200 mg/day dose) on neointima hyperpla- sia was studied. Clopidogrel (75 mg/day) was administered to patients of comparative group. Effective criteria for estimation of the migration-proliferation disorders state in endothelial dysfunction are concentration of the intercellular adhesion molecules (ICAM) and the basic factor of the fibroblasts growth (FGFb); morphological disorders in hyperplastic reactions of neointima - determination of thickness of "intima-media" complex in accordance to the ultrasound duplex scanning data. There was established, that Plestazol constitutes an effective disaggregate preparation, positively impacting decelerating reaction of neointima hyperplasia, including, deceleration of the smooth- muscle cells migration into subendotelial layer in the formation zone of the femoro- popliteal shunt distal anastomosis.

Abstract
BACKGROUND Although international guidelines recommend cilostazol as first-line therapy for peripheral arterial disease (PAD) because it improves the symptoms and quality of life, it remains an underused agent for amputation-free survival. The objective of this study was to evaluate the practice among Italian physicians of the use of cilostazol in patients suffering from peripheral arterial disease (PAD). METHODS For the present study, a cross-sectional survey was carried out. Physicians specialized in the medical and/or surgical treatment of PAD and who prescribe cilostazol regularly were invited to a phone interview. A nationally-representative probability sample of hospital-based physicians who diagnose and treat patients with PAD was randomly selected among the members of the Italian Physicians' Association. RESULTS Out of a total of 641 physicians contacted, 250 of them (39%) accepted to take part in this survey. Reasons of survey refusal were the non-attitude to prescribe cilostazol (45%), or unspecified motivations (16%). Among the 250 physicians participating the survey: 120 were vascular surgeons, 80 internal medicine doctors, 50 angiologists. Cilostazol was suggested in 79% of patients with symptomatic intermittent claudication, and in 30% of patients who had undergone revascularization. The majority of physicians stated to prescribe cilostazol at recommended dosage of 100 mg bid (46.4%). The principal reason to suggest a reduced drug dosage was to limit early side effect at the time of treatment onset, but the increase to the full dose of cilostazol is suggested by 91.3% of interviewed within 4 weeks. Sixty-three percent of physicians affirmed to prescribe cilostazol as a continuous treatment for a mean of 4 months, while a lifelong treatment was suggested by 17.6% of participants. CONCLUSIONS Among physicians who habitually prescribe cilostazol adherence to the recommended drug dosage and length of treatment is high. The prescription of cilostazol is particularly appreciated in patients with symptomatic intermittent claudication, even before any non-invasive diagnosis of PAD, and before any invasive therapy. Finally a relevant number of physicians regularly prescribe cilostazol also after revascularization, advocating the anti-restenotic properties of the drug.

Abstract
PURPOSE The purpose of this study was to compare the efficacy and safety of cilostazol versus acetylsalicylic acid (ASA) for amelioration of lower limb ischemia in type 2 diabetes. DESIGN Prospective, randomized positive-controlled open clinical trial. SUBJECTS AND SETTING Eighty-nine patients with type 2 diabetes mellitus and symptoms of lower limb ischemia (perceptions of coldness of the lower limbs, numbness, intermittent claudication, or pain at rest) present for 6 months or more that had not significantly changed within the past 3 months participated in the study. All subjects had an initial transcutaneous oxygen pressure (TcpO2) of less than 40 mm Hg in the foot when measured in the supine position. Subjects included 46 males and 43 females; their ages ranged from 35 to 80 years. METHODS Participants were randomly allocated to 2 groups, one was treated with cilostazol 100 mg taken twice daily (n = 48), and a second group took 100 mg of ASA daily (n = 41) for 8 weeks. Clinical assessment included measurement of transcutaneous oxygenation, and symptoms associated with lower limb ischemia. Blood analyses included a full blood panel, coagulation screen, renal function tests, hepatic function tests, and lipid profiles. All tests were performed at baseline and repeated at 8 weeks. RESULTS Age, duration of diabetes, diabetic complications, lower limb ischemic symptoms, TcpO2, and smoking status did not differ between the 2 groups. In contrast, TcpO2 significantly improved from 37.1 ± 11.9 mm Hg to 42.0 ± 9.7 mm Hg in the cilostazol-treated group (P < .05), whereas no significant change was observed in the ASA-treated group (P > .05). Ischemic symptoms such as intermittent claudication (P = .009), perception of limb coldness (P = .008), and pain at rest (P = .017) showed greater improvement in the cilostazol-treated group when compared to subjects treated with ASA. Approximately 10% of patients treated with cilostazol experienced adverse side effects (palpitations, headache, diarrhea). Cilostazol was not found to have significant detrimental effects in hematologic or biochemical indices, including renal, hepatic, and blood coagulant function tests. CONCLUSIONS We found that 8 weeks of treatment with cilostazol 100 mg daily was safe and well tolerated for the treatment of type 2 diabetes with lower limb ischemic disease.

Abstract
OBJECTIVE To examine the comparative efficacy and safety of different antiplatelet regimens in patients with prior non-cardioembolic ischaemic stroke or transient ischaemic attack. DESIGN Systematic review and network meta-analysis. DATA SOURCES As on 31 March 2015, all randomised controlled trials that investigated the effects of antiplatelet agents in the long-term (≥ 3 months) secondary prevention of non-cardioembolic transient ischaemic attack or ischaemic stroke were searched and identified. OUTCOME MEASURES The primary outcome measure of efficacy was serious vascular events (non-fatal stroke, non-fatal myocardial infarction and vascular death). The outcome measure of safety was any bleeding. RESULTS A total of 36 randomised controlled trials (82,144 patients) were included. Network meta-analysis showed that cilostazol was significantly more effective than clopidogrel (OR 0.77, 95% credible interval 0.60-0.98) and low-dose (75-162 mg daily) aspirin (0.69, 0.55-0.86) in the prevention of serious vascular events. Aspirin (50 mg daily) plus dipyridamole (400 mg daily) and clopidogrel reduced the risk of serious vascular events compared with low-dose aspirin; however, the difference was not statistically significant. Furthermore, low-dose aspirin was as effective as higher daily doses. Cilostazol was associated with a significantly lower bleeding risk than most of the other regimens. Moreover, aspirin plus clopidogrel was associated with significantly more haemorrhagic events than other regimens. Direct comparisons showed similar results as the network meta-analysis. CONCLUSIONS Cilostazol was significantly more effective than aspirin and clopidogrel alone in the long-term prevention of serious vascular events in patients with prior non-cardioembolic ischaemic stroke or transient ischaemic attack. Cilostazol was associated with a significantly lower bleeding risk than low-dose aspirin (75-162 mg daily) and aspirin (50 mg daily) plus dipyridamole (400 mg daily). Low-dose aspirin was as effective as higher daily doses. However, further large, randomised, controlled, head-to-head trials are needed, especially in non-Asian ethnic groups.

Abstract
Background/Objectives Addition of cilostazol or sarpogrelate to the standard dual antiplatelet therapy of aspirin and clopidogrel has been implemented in patients that underwent percutaneous coronary intervention (PCI) with stents in Korea. This study aimed to evaluate the efficacy and safety of triple antiplatelet therapies. Methods This retrospective cohort study was performed using the Korean National Insurance Claim Data of the Health Insurance Review and Assessment Service from January 1, 2009 to December 31, 2014. The study cohort population consisted of patients with ischemic heart diseases and a history of PCI. They were treated with antiplatelet therapy of aspirin, clopidogrel (AC); aspirin, clopidogrel, cilostazol (ACCi); or aspirin, clopidogrel, sarpogrelate (ACSa) during the index period from January 1, 2010 to December 31, 2011. During the follow-up period up to December 31, 2014, the major adverse cardiac or cerebral events (MACCE) including death, myocardial infarction, target lesion revascularization, and ischemic stroke were assessed. Bleeding complications were also evaluated as adverse drug events. Results Out of 93,876 patients with PCI during the index period, 69,491 patients started dual (AC) or triple therapy (ACSa or ACCi). The clinical outcomes of comparing ACSa and ACCi therapy showed beneficial effects in the ACSa group in the prevention of subsequent cardiac or cerebral events. After Propensity score-matching between ACSa and ACCi groups, there were significant differences in MI and revascularization, with corresponding HR of 0.38 (95% CI, 0.20–0.73) and 0.66 (95% CI, 0.53–0.82) in ACSa vs. ACCi at 12 months, respectively. At the 24-month follow-up, the triple therapy groups (ACS or ACC) had a higher incidence of MACCE compared to the dual therapy (AC) group; ACSa vs. AC HR of 1.69 (95% CI, 1.62–1.77); ACC vs. AC HR of 1.22 (95% CI, 1.06–1.41). There was no significant difference in severe or life-threatening bleeding risk among three groups; ACSa vs. AC, HR of 0.68 (95% CI, 0.37–1.24), ACCi vs. AC, HR of 0.91 (95% CI, 0.77–1.09). Conclusion Sarpogrelate-containing triple antiplatelet therapy demonstrated comparable rates of MACCE prevention to the conventional dual antiplatelet therapy after PCI without significantly increasing bleeding risk during the two-year follow-up period.

Abstract
Doxorubicin (Dox) is an effective anti-cancer drug, but its use is limited because of its adverse effect of inducing irreversible dilated cardiomyopathy. Cilostazol (Cilo), a potent phosphodiesterase III inhibitor, has been reported to have an anti-inflammatory effect. Here, we investigated whether Cilo has a protective effect against Dox-induced cardiomyopathy (DIC). Mice were randomly divided into four groups: saline control, Dox (15 mg/kg), Dox (15 mg/kg) plus Cilo (50mg/kg), and Cilo (50mg/kg). The results showed that the coadministration of Dox and Cilo significantly enhanced left-ventricular systolic function compared with Dox alone. In addition, Cilo treatment significantly reduced Dox-induced perivascular fibrosis, collagen concentration, and connective growth factor expression in the heart. Also, Cilo administration markedly reduced Dox-induced levels of serum B-type natriuretic peptide, dysferlin, high-mobility group protein B1, Toll-like receptor 4, nuclear factor-κB p65, and cyclooxygenase-2. Furthermore, Cilo treatment significantly reduced Dox-induced oxidative stress by lowering the translocation of Nrf2 into the nucleus and the expression of NQO1, heme oxygenase 1, and superoxide dismutase-1. Our results suggest that Cilo may be a potential antifibrotic, antioxidative, and anti-inflammatory drug for DIC.

Abstract
OBJECTIVE Cilostazol, a phosphodiesterase 3, has been widely used in patients with arterial disease and is known to have additional beneficial effects on dyslipidemia. However, the effect of cilostazol on hepatic steatosis has not been fully elucidated. We investigated the effect of cilostazol on hepatic ABCA1 expression and hepatic steatosis in diet-induced obesity mice model. METHODS Hepatic ABCA1 expression and lipid accumulation were analyzed in HepG2 cell lines treated with cilostazol. Male C57BL/6 mice were randomly divided into three groups: (1) fed normal chow diet with vehicle; (2) fed high-fat diet (HFD) with vehicle; (3) fed HFD with cilostazol. Cilostazol (30 mg/kg) was orally administered once daily for 9 weeks. RESULTS Cilostazol significantly enhanced ABCA1 expression and restored ABCA1 expression reduced by palmitate in HepG2 cells. Cilostazol treatment ameliorated lipid accumulation induced by palmitate, and this effect was diminished when ABCA1 or LRP1 was silenced by small interference RNA. After silencing of LRP1, ABCA1 expression was decreased in HepG2 cells. Cilostazol significantly enhanced hepatic ABCA1 expression and decreased hepatic fat in HFD-fed mice. Hepatic expression of cleaved caspase-3 and PARP1 was also decreased in HFD-fed mice treated with cilostazol. CONCLUSIONS Cilostazol ameliorated hepatic steatosis and increased ABCA1 expression in the hepatocytes. Enhancing ABCA1 expression with cilostazol represents a potential therapeutic avenue for treatment of hepatic steatosis.

Abstract
It has been shown that triple antiplatelet therapy with cilostazol results in better clinical outcomes than dual therapy in patients treated with a first-generation drug-eluting stent (DES); however, it is unclear whether triple antiplatelet therapy has a similar efficacy after the implantation of second-generation DES.In the COACT (Cath Olic medical center percutAneous Coronary in Tervention) registry, 1248 study subjects who underwent percutaneous coronary intervention with an everolimus- or zotarolimus-eluting stent (Endeavor, Xience V, or Promus) were analyzed. The patients were divided into 2 groups after propensity score matching (n = 724; M = 422 [58.3%]; mean age = 66.1 ± 11.0 years): Group 1: patients treated with dual antiplatelet drugs (aspirin and clopidogrel; n = 362; M = 213 [58.8%]; mean age = 65.6 ± 11.7 years); Group 2: patients treated with triple antiplatelet drugs (aspirin, clopidogrel, and cilostazol; n = 362; M = 209 [57.7%]; mean age = 65.6 ± 11.7 years). The mean follow-up duration was 13 ± 10 months, and the cumulative incidence of major cardiovascular events (MACE) was 6.3% in Group 1 and 7.7% in Group 2. There were no significant differences in MACE (death, nonfatal myocardial infarction, and stroke) between the 2 groups (OR, 1.210; 95% CI: 0.772-1.898; P = 0.406). Kaplan-Meier curves for MACE did not show any survival benefit for triple antiplatelet therapy, even in patients with acute coronary syndrome.In patients treated with a second-generation DES implantation, there is no added clinical benefit to using triple rather than dual antiplatelet therapy.

Abstract
OBJECTIVE To evaluate the bioequivalence of50 mg cilostazol tablets manufactured locally (Citazol®) and originally (Pletaal®) in healthy Thai volunteers. MATERIAL AND METHOD An open-label, single dose, randomized, two-period, two-sequence, crossover study in 30 healthy volunteers. Each volunteer received a 50 mg cilostazol tablet of bothformulations with a washoutperiodofat least 14 days. Blood samples were obtained atpre-dose and over 48 hours after dosing. Cilostazolplasma concentrations were quantified by using liquid chromatography with tandem mass spectrometry (LC-MS/MS). RESULTS The 30 volunteers completed the entire study. The geometric mean ratios (GAM) (test/reference) between the two formulations of cilostazol were 112.38% (101.70%-124.19%) for Cmax; 103.66% (96.06%-111.86%) for AUC0-48; and 95.14% (86.12%-105.12%)forAUC0-∞. There was no statistical difference ofthe Tmax between the twoformulations (p>0.05). No serious adverse events related to the studied drugs were found. CONCLUSION No significant difference in the analyzed pharmacokineticparameters was found between the twoformulations of 50 mg cilostazol tablets. Therefore, it can be concluded that these two cilostazol tablet formulations were considered bioequivalent.

Abstract
Autophagy is a vital pathway for the removal of β-amyloid peptide (Aβ) and the aggregated proteins that cause Alzheimer’s disease (AD). We previously found that cilostazol induced SIRT1 expression and its activity in neuronal cells, and thus, we hypothesized that cilostazol might stimulate clearances of Aβ and C-terminal APP fragment β subunit (APP-CTFβ) by up-regulating autophagy.When N2a cells were exposed to soluble Aβ1–42, protein levels of beclin-1, autophagy-related protein5 (Atg5), and SIRT1 decreased significantly. Pretreatment with cilostazol (10–30 μM) or resveratrol (20 μM) prevented these Aβ1–42 evoked suppressions. LC3-II (a marker of mammalian autophagy) levels were significantly increased by cilostazol, and this increase was reduced by 3-methyladenine. To evoke endogenous Aβ overproduction, N2aSwe cells (N2a cells stably expressing human APP containing the Swedish mutation) were cultured in medium with or without tetracycline (Tet+ for 48 h and then placed in Tet- condition). Aβ and APP-CTFβ expressions were increased after 12~24 h in Tet- condition, and these increased expressions were significantly reduced by pretreating cilostazol. Cilostazol-induced reductions in the expressions of Aβ and APP-CTFβ were blocked by bafilomycin A1 (a blocker of autophagosome to lysosome fusion). After knockdown of the SIRT1 gene (to ~40% in SIRT1 protein), cilostazol failed to elevate the expressions of beclin-1, Atg5, and LC3-II, indicating that cilostazol increases these expressions by up-regulating SIRT1. Further, decreased cell viability induced by Aβ was prevented by cilostazol, and this inhibition was reversed by 3-methyladenine, indicating that the protective effect of cilostazol against Aβ induced neurotoxicity is, in part, ascribable to the induction of autophagy. In conclusion, cilostazol modulates autophagy by increasing the activation of SIRT1, and thereby enhances Aβ clearance and increases cell viability.

Abstract
Recent studies have demonstrated that the plasma soluble receptor for advanced glycation end-products (sRAGE) play a major role in developing macrovascular complications of type 2 diabetes, including peripheral arterial occlusion disease (PAOD). Cilostazol is an antiplatelet, antithrombotic agent, which has been used for the treatment of PAOD. We hypothesized that cilostazol attenuates the severity of PAOD in patients with type 2 diabetes through the augmentation of plasma sRAGE. Ninety type 2 diabetic patients with PAOD defined as intermittent claudication with ankle-brachial index (ABI) ≦0.9 were recruited for an open-labeled, placebo-controlled study for 52 weeks with oral cilostazol 100 mg twice daily (n = 45) or placebo (n = 45). Fasting plasma sRAGE, endothelial variables of E-selectin, soluble vascular cell adhesion molecule-1 (sVCAM-1), and inflammatory markers of high-sensitivity C-reactive protein (hsCRP) and tumor necrosis factor-α (TNF-α) were determined. After completely the 52-week treatment program, the ABI values were elevated in cilostazol group (P < 0.001). The plasma sRAGE was significantly increased (P = 0.007), and hsCRP, sVCAM, and E-selectin concentrations were significantly decreased (P = 0.028, <0.001 and <0.001, respectively) with cilostazol treatment. In a partial correlation analysis with adjustments for sex and age, the net change of sRAGE significantly correlated with the change of ABI in the cilostazol group (P = 0.043). In a stepwise multiple regression model, only the change with regards to sRAGE was significantly associated with the change of ABI (P = 0.046). Our results suggest that cilostazol may effectively attenuate the severity of PAOD in patients with type 2 diabetes. Plasma sRAGE plays a role as an independent predictor for improving the index of PAOD.
