The Influence of Non-High-Density Lipoprotein Cholesterol on the Efficacy of Genotype-Guided Dual Antiplatelet Therapy in Preventing Stroke Recurrence. J Stroke 2024; 26:231-241. [PMID: 38836270 PMCID: PMC11164593 DOI: 10.5853/jos.2024.00367] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2024] [Revised: 03/07/2024] [Accepted: 03/08/2024] [Indexed: 06/06/2024] Open
Abstract
BACKGROUND AND PURPOSE Non-high-density lipoprotein cholesterol (non-HDL-C), which represents the total cholesterol content of all pro-atherogenic lipoproteins, has recently been included as a new target for lipid-lowering therapy in high-risk atherosclerotic patients in multiple guidelines. Herein, we aimed to explore the relationship between non-HDL-C level and the efficacy and safety of ticagrelor-aspirin versus clopidogrel-aspirin in preventing stroke recurrence. METHODS This study comprised a post hoc analysis of the CHANCE-2 (Ticagrelor or Clopidogrel in High-Risk Patients with Acute Nondisabling Cerebrovascular Events II) trial, from which 5,901 patients with complete data on non-HDL-C were included and categorized by median non-HDL-C levels, using a cutoff of 3.5 mmol/L. The primary efficacy and safety outcomes were recurrent stroke and severe or moderate bleeding within 90 days. RESULTS Ticagrelor-aspirin significantly reduced the risk of recurrent stroke in patients with low non-HDL-C (71 [4.8%] vs. 119 [7.7%]; adjusted hazard ratio [HR] 0.54; 95% confidence interval [CI], 0.40-0.74), but not in those with high non-HDL-C (107 [7.3%] vs. 108 [7.6%]; adjusted HR, 0.88; 95% CI, 0.67-1.16), compared with clopidogrel-aspirin (P for interaction=0.010). When analyzed as a continuous variable, the benefit of ticagrelor-aspirin for recurrent stroke decreased as non-HDL-C levels increased. No significant differences in the treatment assignments across the non-HDL-C groups were observed in terms of the rate of severe or moderate bleeding (5 [0.3%] vs. 8 [0.5%] in the low non-HDL-C group; 4 [0.3%] vs. 2 [0.1%] in the high non-HDL-C group; P for interaction=0.425). CONCLUSION CHANCE-2 participants with low non-HDL-C levels received more clinical benefit from ticagrelor-aspirin versus clopidogrel-aspirin compared to those with high non-HDL-C, following minor ischemic stroke or transient ischemic attack.

Clopidogrel-Related High Residual Platelet Reactivity Associated with Estimated Glomerular Filtration Rate in Patients with Acute Ischemic Stroke. Cerebrovasc Dis Extra 2023; 13:83-89. [PMID: 37812922 PMCID: PMC10620003 DOI: 10.1159/000534466] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/11/2023] [Accepted: 10/02/2023] [Indexed: 10/11/2023] Open
Abstract
INTRODUCTION There are few studies on the relationship between the occurrence of clopidogrel-related high residual platelet reactivity (HRPR) and estimated glomerular filtration rate (eGFR) at admission in patients with ischemic stroke. The aim of this study was to investigate the possible relationship between the two. METHODS Patients who were hospitalized and diagnosed with acute ischemic stroke were recruited from July 1, 2017, to June 30, 2018, at Shanghai TCM-Integrated Hospital. Renal function was measured within 24 h of enrollment and eGFR was calculated. Patients were tested for platelet reactivity using the VerifyNow system after 7 days of antiplatelet therapy with clopidogrel 75 mg/d alone, and patients with P2Y12 reaction unit values ≥230 were diagnosed with HRPR. The association between HRPR and eGFR was analyzed. RESULTS A total of 274 patients were enrolled in the study, of whom 91 (33.21%) had HRPR. Multivariate logistic regression analysis suggested that an increased risk of HRPR was independently associated with female sex and reduced eGFR (female sex: OR = 2.24, 95% CI: 1.26-3.99, p = 0.006; mild chronic kidney disease [CKD]: OR = 2.95, 95% CI: 1.47-5.93, p = 0.002; moderate CKD: OR = 3.07, 95% CI: 1.08-8.75, p = 0.04). CONCLUSION Decreased eGFR is an independent risk factor for the occurrence of HRPR in patients with ischemic stroke.

Abstract
BACKGROUND Evidence on the risk-benefit ratio of dual antiplatelet therapies among patients with stroke and impaired renal function is limited and inconsistent. OBJECTIVE To investigate the effect of renal function on the efficacy and safety of ticagrelor-aspirin versus clopidogrel-aspirin treatment. DESIGN Post hoc analysis of a multicenter, randomized, double-blind, placebo-controlled trial. (ClinicalTrials.gov: NCT04078737). SETTING 202 centers in China. PATIENTS CYP2C19 loss-of-function allele carriers with minor stroke or transient ischemic attack. INTERVENTION Ticagrelor-aspirin and clopidogrel-aspirin. MEASUREMENTS Renal function was evaluated by estimated glomerular filtration rate (eGFR) levels. The primary efficacy and safety outcomes were recurrent stroke and severe or moderate bleeding within 90 days, respectively. RESULTS Among 6378 patients, 4050 (63.5%) had normal (eGFR ≥90 mL/min/1.73 m2), 2010 (31.5%) had mildly decreased (eGFR 60 to 89 mL/min/1.73 m2), and 318 (5.0%) had moderately to severely decreased (eGFR <60 mL/min/1.73 m2) renal function. The corresponding differences in recurrent stroke between ticagrelor-aspirin and clopidogrel-aspirin for normal, mildly decreased, and moderately to severely decreased renal function was -2.8 percentage points (95% CI, -4.4 to -1.3 percentage points) (hazard ratio [HR], 0.63 [CI, 0.49 to 0.81]), -0.2 percentage point (CI, -2.4 to 2.0 percentage points) (HR, 0.98 [CI, 0.69 to 1.39]), and 3.7 percentage points (CI, -2.3 to 10.1 percentage points) (HR, 1.31 [CI, 0.48 to 3.55]), respectively. Rates of severe or moderate bleeding did not substantially differ by treatment assignments across eGFR categories. LIMITATION Renal function was only evaluated by using eGFR, and the proportion of patients with severely decreased renal function was low. CONCLUSION Patients with normal, rather than impaired, renal function received greater benefit from ticagrelor-aspirin versus clopidogrel-aspirin.

Abstract
BACKGROUND Antiplatelet agents are widely used to prevent cardiovascular events. The risks and benefits of antiplatelet agents may be different in people with chronic kidney disease (CKD) for whom occlusive atherosclerotic events are less prevalent, and bleeding hazards might be increased. This is an update of a review first published in 2013. OBJECTIVES To evaluate the benefits and harms of antiplatelet agents in people with any form of CKD, including those with CKD not receiving renal replacement therapy, patients receiving any form of dialysis, and kidney transplant recipients. SEARCH METHODS We searched the Cochrane Kidney and Transplant Register of Studies up to 13 July 2021 through contact with the Information Specialist using search terms relevant to this review. Studies in the Register are identified through searches of CENTRAL, MEDLINE, and EMBASE, conference proceedings, the International Clinical Trials Register (ICTRP) Search Portal and ClinicalTrials.gov. SELECTION CRITERIA We selected randomised controlled trials of any antiplatelet agents versus placebo or no treatment, or direct head-to-head antiplatelet agent studies in people with CKD. Studies were included if they enrolled participants with CKD, or included people in broader at-risk populations in which data for subgroups with CKD could be disaggregated. DATA COLLECTION AND ANALYSIS Four authors independently extracted data from primary study reports and any available supplementary information for study population, interventions, outcomes, and risks of bias. Risk ratios (RR) and 95% confidence intervals (CI) were calculated from numbers of events and numbers of participants at risk which were extracted from each included study. The reported RRs were extracted where crude event rates were not provided. Data were pooled using the random-effects model. Confidence in the evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. MAIN RESULTS We included 113 studies, enrolling 51,959 participants; 90 studies (40,597 CKD participants) compared an antiplatelet agent with placebo or no treatment, and 29 studies (11,805 CKD participants) directly compared one antiplatelet agent with another. Fifty-six new studies were added to this 2021 update. Seven studies originally excluded from the 2013 review were included, although they had a follow-up lower than two months. Random sequence generation and allocation concealment were at low risk of bias in 16 and 22 studies, respectively. Sixty-four studies reported low-risk methods for blinding of participants and investigators; outcome assessment was blinded in 41 studies. Forty-one studies were at low risk of attrition bias, 50 studies were at low risk of selective reporting bias, and 57 studies were at low risk of other potential sources of bias. Compared to placebo or no treatment, antiplatelet agents probably reduces myocardial infarction (18 studies, 15,289 participants: RR 0.88, 95% CI 0.79 to 0.99, I² = 0%; moderate certainty). Antiplatelet agents has uncertain effects on fatal or nonfatal stroke (12 studies, 10.382 participants: RR 1.01, 95% CI 0.64 to 1.59, I² = 37%; very low certainty) and may have little or no effect on death from any cause (35 studies, 18,241 participants: RR 0.94, 95 % CI 0.84 to 1.06, I² = 14%; low certainty). Antiplatelet therapy probably increases major bleeding in people with CKD and those treated with haemodialysis (HD) (29 studies, 16,194 participants: RR 1.35, 95% CI 1.10 to 1.65, I² = 12%; moderate certainty). In addition, antiplatelet therapy may increase minor bleeding in people with CKD and those treated with HD (21 studies, 13,218 participants: RR 1.55, 95% CI 1.27 to 1.90, I² = 58%; low certainty). Antiplatelet treatment may reduce early dialysis vascular access thrombosis (8 studies, 1525 participants) RR 0.52, 95% CI 0.38 to 0.70; low certainty). Antiplatelet agents may reduce doubling of serum creatinine in CKD (3 studies, 217 participants: RR 0.39, 95% CI 0.17 to 0.86, I² = 8%; low certainty). The treatment effects of antiplatelet agents on stroke, cardiovascular death, kidney failure, kidney transplant graft loss, transplant rejection, creatinine clearance, proteinuria, dialysis access failure, loss of primary unassisted patency, failure to attain suitability for dialysis, need of intervention and cardiovascular hospitalisation were uncertain. Limited data were available for direct head-to-head comparisons of antiplatelet drugs, including prasugrel, ticagrelor, different doses of clopidogrel, abciximab, defibrotide, sarpogrelate and beraprost. AUTHORS' CONCLUSIONS Antiplatelet agents probably reduced myocardial infarction and increased major bleeding, but do not appear to reduce all-cause and cardiovascular death among people with CKD and those treated with dialysis. The treatment effects of antiplatelet agents compared with each other are uncertain.

Abstract
BACKGROUND AND PURPOSE The age, body mass index, chronic kidney disease, diabetes, and genotyping (ABCD-GENE) score is a validated risk score integrating CYP2C19 genotypes with clinical risk factors influencing clopidogrel response that would allow the more precise identification of subjects at risk for high platelet reactivity and adverse clinical outcomes. Our objective was to further verify application of the ABCD-GENE score and investigate appropriate cutoff value in patients with minor stroke or transient ischemic attack. METHODS In this post-analysis of the CHANCE trial (Clopidogrel in High-Risk Patients With Acute Nondisabling Cerebrovascular Events), the ABCD-GENE score was calculated for all patients enrolled in this study. By using the proposed cutoff of 10, patients were stratified as being at high risk for high platelet reactivity or not. We further categorized the ABCD-GENE score to 0 to 5, 6 to 24, and >24 to investigate the cutoff value of this scale in clinical application. Stroke recurrence at 3 months was considered as the primary outcome. RESULTS Among a total of 2923 patients with minor stroke/transient ischemic attack, there were 2273 (77.76%) with ABCD-GENE score <10 and 650 (22.24%) patients with ABCD-GENE score ≥10. Compared with the aspirin alone, hazard ratios (95% CIs) of the clopidogrel-aspirin therapy for stroke recurrence were 0.70 (0.54-0.91) and 0.76 (0.46-1.24), among patients of ABCD-GENE scores <10 and ABCD-GENE scores ≥10, respectively. Stratified analyses by ABCD-GENE score 0 to 5, 6 to 24, and >24, hazard ratios of the clopidogrel-aspirin therapy for stroke recurrence were 0.57 (95% CI, 0.38-0.85), 0.78 (0.58-1.06), and 1.20 (0.44-3.28) (P value for trend=0.0052). CONCLUSIONS Among Chinese minor stroke/transient ischemic attack population, the efficacy of clopidogrel-aspirin therapy was decreased in patients with higher ABCD-GENE score. Our study suggests that CYP2C19 genotypes and clinical risk factors can be integrated by ABCD-GENE score to estimate the efficacy of clopidogrel-aspirin therapy.

Abstract
Chronic kidney disease (CKD) affects both brain structure and function. Patients with CKD have a higher risk of both ischemic and hemorrhagic strokes. Age, prior disease history, hypertension, diabetes, atrial fibrillation, smoking, diet, obesity, and sedimentary lifestyle are most common risk factors. Renal-specific pathophysiologic derangements, such as oxidative stress, chronic inflammation, endothelial dysfunction, vascular calcification, anemia, gut dysbiosis, and uremic toxins are important mediators. Dialysis initiation constitutes the highest stroke risk period. CKD significantly worsens stroke outcomes. It is essential to understand the risks and benefits of established stroke therapeutics in patients with CKD, especially in those on dialysis. Subclinical cerebrovascular disease, such as of silent brain infarction, white matter lesions, cerebral microbleeds, and cerebral atrophy are more prevalent with declining renal function. This may lead to functional brain damage manifesting as cognitive impairment. Cognitive dysfunction has been linked to poor compliance with medications, and is associated with greater morbidity and mortality. Thus, understanding the interaction between renal impairment and brain is important in to minimize the risk of neurologic injury in patients with CKD. This article reviews the link between chronic kidney disease and brain abnormalities associated with CKD in detail.

Liu G, Yang S, Chen S. The correlation between recurrent risk and CYP2C19 gene polymorphisms in patients with ischemic stroke treated with clopidogrel for prevention. Medicine (Baltimore) 2020; 99:e19143.

Abstract
BACKGROUND To explore the correlation between recurrent risk and CYP2C19 gene polymorphisms in patients with ischemic stroke (IS) treated with clopidogrel for prevention. METHODS A total of 289 patients with IS treated with clopidogrel regularly were enrolled in this study, and stroke recurrence of all patients were recorded by follow-up. The correlation between CYP2C19 gene polymorphism and stroke recurrence in patients taking clopidogrel regularly was analyzed. RESULTS After a mean follow-up period of 6 months, there were 289 patients who took clopidogrel regularly, and 41 of which occurred recurrent stroke. Patients of poor metabolizer and intermediate metabolizer had higher risk of recurrent stroke comparing with patients of extensive metabolize, and the odds ratios were 2.88 (95% confidence interval [CI] 1.31-6.33, P = .068) and 3.00 (95% CI 1.09-8.22, P = .027), respectively. The recurrence risk of *2 (G681A)A allele carriers was 3.30 times that of G allele carriers (P = .0065). The recurrence rate of stroke in patients carrying heterozygous and homozygous *2 allele mutant was 1.96 times (P = .071) and 3.30 times (P = .012) that of patients with wild-type genes. Multifactor logistic regression analysis result indicated carrying loss of function (LOF) allele was an independent risk factor of stroke recurrence. CONCLUSION For patients with IS treated with clopidogrel regularly for secondary prevention, poor metabolizer, and intermediate metabolizer patients had higher risk of recurrent stroke comparing with extensive metabolize ones. Carrying CYP2C19 LOF allele is an independent risk factor of stroke recurrence in patients with IS.

Abstract
BACKGROUND AND PURPOSE Studies on using antiplatelet agents for secondary prevention in ischaemic stroke patients with renal dysfunction are limited. The Taiwan Stroke Registry database was used to compare the efficacy of antiplatelet agents. METHODS From the Taiwan Stroke Registry data, 39 174 acute ischaemic stroke patients were identified and were classified into three groups by antiplatelet agent: aspirin, clopidogrel and dual antiplatelet therapy (DAPT) with a combination of aspirin and clopidogrel. The re-stroke incidence and 1-year mortality were stratified by estimated glomerular filtration rate (eGFR) levels at admission: ≥90, 60-89 and <60 ml/min/1.73 m2 or on dialysis. RESULTS Compared to the aspirin group, the re-stroke differences were not statistically significant for the clopidogrel group [adjusted subhazard ratio 0.95, 95% confidence interval (CI) 0.84-1.08] and the DAPT group (adjusted subhazard ratio 1.03, 95% CI 0.77-1.39) after controlling for the competing risk of death. The mortality rate increased as the eGFR level declined. In addition, compared to patients taking aspirin, there was no statistically significant difference in overall 1-year mortality for the clopidogrel group (adjusted hazard ratio 1.11, 95% CI 0.95-1.29) and for the DAPT group (adjusted hazard ratio 1.01, 95% CI 0.67-1.54). The results were consistent in different subgroups stratified by eGFR levels. CONCLUSIONS There was no difference in the risks of recurrent stroke and 1-year mortality amongst ischaemic stroke patients with or without renal dysfunction receiving antiplatelet agents with aspirin, clopidogrel or dual agents with a combination of aspirin and clopidogrel, regardless of their renal dysfunction status.

Abstract
Chronic kidney disease is strongly associated with an increased risk of stroke, small vessel disease, and vascular dementia. Common vascular factors for stroke, such as hypertension, diabetes, and atrial fibrillation, are more prevalent in patients with chronic kidney disease, accounting for this association. However, factors unique to these patients, such as uremia, oxidative stress, and mineral and bone abnormalities, as well as dialysis-related factors are also believed to contribute to risk. Despite improvements in stroke treatment and survival in the general population, the rate of improvement in patients with chronic kidney disease, especially those who are dialysis dependent, has lagged behind. There is a lack of or conflicting evidence that those with renal disease, particularly when advanced or older, consistently derive benefit from currently available preventive and therapeutic interventions for stroke in the general population. In this review, we explore the complexities and challenges of these interventions in the population with renal disease.

Abstract
Objective: To make comparative studies on the effects of different doses of atorvastatin combined with aspirin on inflammatory cytokines, blood lipids, blood glucose, other biochemical indexes and carotid plaques in patients with ischemic cerebrovascular disease (ICVD) and carotid plaques. Method: One hundred and twenty patients with ICVD and carotid plaques admitted by Renmin Hospital, Hubei University of Medicine Hospital from December 2016 to December 2017 were selected and randomly divided into experimental group and control group, 60 cases in each group. Patients in the control group was asked to orally take standard dose of atorvastatin (20 mg/d) combined with aspirin enteric-coated tablets (100 mg/d). Patients in the experimental group was asked to orally take high-dose atorvastatin (40 mg/d) combined with the same amount of aspirin enteric-coated tablets. Patients in two groups were treated for 6 months averagely. The levels of inflammatory factors, changes in blood biochemical parameters and carotid plaque degrees of patients in two groups before and after treatment were inspected and compared. Results: The levels of serum high-sensitivity C-reactive protein (hs-CRP), tumor necrosis factor (TNF-a), interleukin-6 (IL-6) and homocysteine (Hcy) in patients of the experimental group after treatment were higher than those in the control group, difference with statistical significance (p < .05). The total cholesterol (TC), triglyceride (TG) and low density lipoprotein cholesterol (LDL-C) in patients of the experimental group after treatment were lower than those in the control group and before treatment. The high-density lipoprotein cholesterol (HDL-C) was higher than that of the control group and before treatment, the levels of fasting blood glucose (FBS) and glycosylated hemoglobin (HbAIc) in patients of the experimental group significantly increased compared to those before treatment, difference with statistical significance (p < .05). There was no significant change in the control group. The carotid intima-media thickness (IMT) and plaque area in patients of the experimental group were lower than those in the control group and before treatment, difference with statistical significance (p < .05). Conclusion: High-dose atorvastatin combined with aspirin for treatment of patients with ICVD can effectively reduce inflammatory inflammatory cytokine levels in serum and reduce IMT and carotid plaque area. With more obvious effect than lower dose of atorvastatin combined with aspirin, it is easy to cause blood glucose abnormality. So, it is necessary to pay attention to monitoring blood sugar during medication period.

Abstract
Background The present study was designed to evaluate the predictive value of head-neck computed tomography angiography (CTA) combined with ABCD2 score scale for patients with cerebral infarction of vertebrobasilar transient ischemic attack (TIA). Material/Methods A total of 92 patients with TIA who were admitted to our hospital from January 2014 to June 2015 were enrolled in this study. ABCD2 score and CTA combined with ABCD2 score were assessed. Results The incidence of cerebral infarction was highest in the high-risk group, followed by the middle-risk group and low-risk group. The incidence of cerebral infarction was related to the degree of stenosis in head-neck CTA, which was highest in the severe stenosis group, followed by the moderate stenosis group and mild stenosis/normal group, with significant differences. The incidence of cerebral infarction in patients with cerebral artery stenosis was correlated with the incidence of cerebral infarction in the head and neck CTA, which was severe > medium > normal/low (P<0.05). Conclusions The ABCD2 score can accurately predict the early development from TIA to cerebral infarction. If it is used in combination with head-neck CTA; CTA combined ABCD2 score can further improve the accuracy of prediction, which makes it feasible for use in prediction of the development of vertebrobasilar TIA to cerebral infarction.

Abstract
Therapeutic effect of vascular interventional therapy and aspirin combined with defibrase in the treatment of cerebral ischemia in rat model were investigated. Ninety rats were selected to establish cerebral ischemia model. Animal models were randomly divided into observation group and control group, with 45 rats in each group. Rats in observation group were treated with vascular intervention, and control group was treated with aspirin combined with defibrase. Peak systolic velocity (Vs) and end-diastolic velocity (Vd) were compared between two groups before and after 12 months of treatment. Therapeutic effects were compared before and after 6 months, and before and after 12 months of treatment. Vs and Vd of vascular lesions in observation group at 12 months were reduced after treatment, and were significantly lower than those in control group (p<0.05). After treatment, Vs and Vd in observation group were significantly reduced (p<0.05). There was no significant difference in Vs and Vd values between the groups before treatment (p>0.05). NDS scores in observation group were significantly lower than those in control group at 6 months and 1 year after treatment (p<0.05). There were no significant changes in NDS score at 6 and 12 months after treatment in control group compared with pretreatment group (p>0.05). NDS in observation group was significantly reduced at 6 and 12 months after treatment compared with pretreatment level (p<0.05). One year after treatment, incidence of cerebral infarction and transient ischemic attack and mortality in observation group were significantly lower than those in the control group (p<0.05). Intracranial vascular interventional therapy can achieve satisfactory outcomes in the treatment of cerebral ischemia, and can effectively promote nerve function recovery, and reduce the incidence of cerebrovascular diseases and mortality.

Abstract
OBJECTIVES Statin use during hospitalization improves prognosis in patients with ischaemic stroke. However, it remains uncertain whether acute ischaemic stroke patients with chronic kidney disease (CKD) benefit from statin therapy. We investigated the effect of statin use during hospitalization in reducing short-term mortality of patients with ischaemic stroke and CKD. METHODS Data of first-ever ischaemic stroke patients without a history of pre-stroke statin treatment was derived from the China National Stroke Registry. Patients were stratified according to estimated glomerular filtration rate (eGFR): normal renal function (eGFR ≥90 mL/min/1.73 m2), mild CKD (eGFR 60-90 mL/min/1.73 m2) and moderate CKD (eGFR < 60 mL/min/1.73 m2). Multivariate logistic regression analysis was used to evaluate the association between statin use during hospitalization and all-cause mortality with different renal functions at 3-month follow-up. RESULTS Among 5,951 patients included, 2,595 (43.6%) patients were on statin use during hospitalization after stroke (45.7% in patients with normal renal function, 42.0% in patients with mild CKD, and 39.0% in patients with moderate CKD). Compared with the non-statin group, statin use during hospitalization was associated with decreased all-cause mortality in patients with normal renal function (OR 0.65, 95% CI 0.43-0.97, p = 0.04), mild CKD (OR 0.59, 95% CI 0.38-0.91, p = 0.02) and moderate CKD (OR 0.41, 95% CI 0.23-0.75, p = 0.004) at 3-month follow-up. CONCLUSIONS Statin use during hospitalization was associated with decreased 3-month mortality of ischaemic stroke patients with mild and moderate CKD. However, the conclusion should be confirmed in further studies with larger population, especially with moderate CKD.
