Zhang Y, Wang J, Shen N, Jiang J, Xie Y. Safety and efficacy of apixaban versus vitamin K antagonists in patients undergoing dialysis: a systematic review and meta-analysis. Ren Fail 2024; 46:2349114. [PMID: 38770962 PMCID: PMC11110875 DOI: 10.1080/0886022x.2024.2349114] [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: 12/13/2023] [Accepted: 04/10/2024] [Indexed: 05/22/2024] Open
Abstract
BACKGROUND This review aims to evaluate the safety and efficacy of apixaban vs. vitamin K antagonists (VKAs) in patients on dialysis. METHODS All types of studies published on PubMed, Embase, CENTRAL, and Web of Science up to 10 September 2023 and comparing outcomes of apixaban vs. VKA in dialysis patients were eligible. RESULTS Two randomized controlled trials (RCTs) and six retrospective studies were included. Apixaban treatment was associated with significantly lower risk of major bleeding (RR: 0.61; 95% CI: 0.48, 0.77; I2 = 50%) and clinically relevant non-major bleeding (RR: 0.82, 95% CI: 0.68, 0.98, I2 = 9%) compared to VKA. Meta-analysis also showed that the risk of gastrointestinal bleeding (RR: 0.74, 95% CI: 0.64, 0.85, I2 = 16%) and intracranial bleeding (RR: 0.64, 95% CI: 0.49, 0.84, I2 = 0%) was significantly reduced with apixaban. Meta-analysis showed no difference in the risk of ischemic stroke (RR: 0.40, 95% CI: 0.06, 2.69, I2 = 0%), mortality (RR: 1.26, 95% CI: 0.74, 2.16, I2 = 94%) and recurrent venous thromboembolism (RR: 1.02, 95% CI: 0.87, 1.21, I2 = 0%) between the two groups. Subgroup analysis of RCTs showed no difference in bleeding outcomes. CONCLUSIONS Low-quality evidence from a mix of RCTs and retrospective studies shows that apixaban may have better safety and equivalent efficacy as compared to VKA in dialysis patients. Apixaban treatment correlated with significantly reduced risk of major bleeding and clinically relevant nonmajor bleeding in observational studies but not in RCTs. The predominance of retrospective data warrants caution in the interpretation of results.

Abstract
Chronic kidney disease (CKD) remains a significant global health issue and is a leading cause of mortality worldwide. Patients with CKD have an increased risk of developing atrial fibrillation (AF) and venous thromboembolism (VTE). While direct oral anticoagulants (DOACs) have become a standard of care for anticoagulation (AC) in patients with AF and VTE, the appropriate use of these agents in comorbid kidney impairment warrants detailed discussion. This scientific narrative review summarizes the effectiveness and safety of apixaban use in patients with renal dysfunction by assessing the current published pharmacokinetic, interventional, observational, and guideline data. Apixaban is a highly selective, orally active, direct inhibitor of factor Xa, with well-established pharmacokinetics and consistent clinical outcomes across a broad range of patient populations, including those with kidney impairment. Overall, the scientific literature has shown that apixaban has a favorable clinical efficacy and safety profile compared with vitamin K antagonists for patients with AF or VTE and comorbid kidney impairment. These data support the approved label dosing strategy of apixaban in reducing the risk of stroke/systemic embolism in patients with nonvalvular AF and in treating VTE across all ranges of kidney function. Both clinician experience and knowledge of patient-specific factors may be required in the management of comorbid patients with advanced CKD or those requiring dialysis, as data on these patients are limited.

Abstract
Many patients with impaired renal function have concurrent indications for anticoagulant therapy, including atrial fibrillation and venous thromboembolism. For mild chronic kidney disease, data from clinical trials and existing guidelines can be applied to clinical management. The benefits and harms of anticoagulation therapy in patients with more advanced renal impairment are nuanced, as both thrombotic and bleeding risk are increased. Until recently, data regarding anticoagulants in severe renal impairment were primarily observational, but emerging evidence includes a few small clinical trials and the emergence of novel agents hypothesized to have improved efficacy and safety in this population. In this review, we summarize existing data on anticoagulation in patients with chronic kidney disease. We suggest a framework for anticoagulation decision-making in the burgeoning worldwide population of patients with chronic kidney disease.

Abstract
The nuanced landscape of anticoagulation therapy in patients with chronic kidney disease (CKD) presents a formidable challenge, intricately balancing the dual hazards of hemorrhage and thrombosis. These patients find themselves in a precarious position, teetering on the edge of these risks due to compromised platelet functionality and systemic disturbances within their coagulation frameworks. The management of such patients necessitates a meticulous approach to dosing adjustments and vigilant monitoring to navigate the perilous waters of anticoagulant therapy. This is especially critical considering the altered pharmacokinetics in CKD, where the clearance of drugs is significantly impeded, heightening the risk of accumulation and adverse effects. In the evolving narrative of anticoagulation therapy, the introduction of direct oral anticoagulants (DOACs) has heralded a new era, offering a glimmer of hope for those navigating the complexities of CKD. These agents, with their promise of easier management and a reduced need for monitoring, have begun to reshape the contours of care, particularly for patients not yet on dialysis. However, this is not without its caveats. The application of DOACs in the context of advanced CKD remains a largely uncharted territory, necessitating a cautious exploration to unearth their true potential and limitations. Moreover, the advent of innovative strategies such as left atrial appendage occlusion (LAAO) underscores the dynamic nature of anticoagulation therapy, potentially offering a tailored solution for those at the intersection of CKD and elevated stroke risk. Yet the journey toward integrating such advancements into standard practice is laden with unanswered questions, demanding rigorous investigation to illuminate their efficacy and safety across the spectrum of kidney disease. In summary, the management of anticoagulation in CKD is a delicate dance, requiring a harmonious blend of precision, caution, and innovation. As we venture further into this complex domain, we must build upon our current understanding, embracing both emerging therapies and the need for ongoing research. Only then can we hope to offer our patients a path that navigates the narrow strait between bleeding and clotting, toward safer and more effective care.

The Safety and Effectiveness of Apixaban in Patients with End-Stage Kidney Disease on Dialysis: A Retrospective Observational Study. J Clin Med 2024; 13:1351. [PMID: 38592193 PMCID: PMC10931560 DOI: 10.3390/jcm13051351] [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: 02/04/2024] [Revised: 02/18/2024] [Accepted: 02/23/2024] [Indexed: 04/10/2024] Open
Abstract
Background: Apixaban has been increasingly utilized for various FDA-approved indications, including stroke prevention and venous thromboembolism (VTE) treatment in patients with end stage kidney disease (ESKD) on hemodialysis. However, the safety and efficacy of its use in this population is not well established. Hence, the purpose of this study is to evaluate the safety and effectiveness of apixaban by examining outcomes in this population. Methods: This was a retrospective observational study that involved adults with ESKD who were on hemodialysis and prescribed apixaban from our hospital's outpatient pharmacy between 1 May 2015, and 31 March 2022. Demographics, apixaban indications, dose appropriateness, concomitant antiplatelet use, and comorbidities data were collected. Bleeding and thromboembolic events were also collected. Results: Sixty-six patients fulfilled the inclusion criteria, 50% of them males. Median age was 71 (63.5-82) years, and the median BMI 28.2 (59.5-86.25) kg/m2. The median follow-up time was 5 (1.9-12.3) months. Concomitant antiplatelet use (39.4%) and high medication adherence (84.8%) were observed. During follow-up, major bleeding events occurred in 15.2% of cases, with minor bleeding being more common (36.4%), and VTE and stroke events occurred in 4.5% of cases; appropriate dosing was prevalent (62.1%), and there was an overall all-cause mortality rate of 34.8%. Most patients received a 2.5 mg BID apixaban dose (56.1%), including both NVAF and VTE groups. Notably, the multivariate logistic regression analysis indicated that weight, and daily dose were insignificant predictors of bleeding events (p = 0.104, 0.591), however, the BMI was the main independent risk factor for bleeding in this population [OR = 0.9, 95% CI: 0.8-0.99; p = 0.023]. Conclusions: Our analysis of apixaban-treated ESKD patients highlights that the risk of bleeding is significant, and BMI was the main independent risk factor. A larger prospective study is needed to confirm our findings.

Abstract
Chronic kidney disease (CKD) is being diagnosed increasingly worldwide. It is often identified in individuals with comorbidities, which may increase the already heightened risk of thrombosis and hemorrhage associated with CKD. Oral anticoagulation is an effective means of reducing rates of ischemic stroke and systemic embolism in patients with atrial fibrillation and minimizes the morbidity and mortality caused by venous thromboembolic disease. Despite the proven benefits in the majority of patients, these have not been so clearly realized in patients with CKD due to the precarious balance between bleeding and thromboembolic complications. In this review, the current status of anticoagulant utilization in CKD is examined, and some practical recommendations are put forward to assist in the decision-making process of safely anticoagulating patients with CKD diagnosed with atrial fibrillation and venous thromboembolism.

Abstract
Optimal anticoagulation in patients with end-stage renal disease ESRD is a matter of debate since these patients are not included in randomized controlled trials (RCTs). Evolving data are in favor of apixaban compared to warfarin. METHODS We extracted data from 2 RCTs, 5 retrospective cohort studies and 3 large data-based studies. Both dosing regimens of apixaban, standard or reduced, were accepted. In most studies characteristics of patients were balanced between arms. Patients with either atrial fibrillation (AF) or venous thromboembolism (VTE) were included. Quality of studies was graded as high and the funnel plot did not detect any publication bias. In total we analyzed the outcome of 6693 ESRD patients treated with apixaban and 19,836 treated with warfarin. Our analysis was performed by using the random effects model. We report our data as Risk Ratio (RR) and associated 95 % confidence interval values (95 %, CI). RESULTS The RR (95 % CI) of major bleeding was 0.69 (0.57-0.84) p = 0.0002 in favor of apixaban vs warfarin with heterogeneity to be statistically significant I2 63% p = 0.004. Meta-regression analysis with year of publication as moderator shows in bubble plotting that studies published earlier than 2018 were plotted as outliers. The RR (95 % CI) of clinically relevant non-major bleeding (CRNMB) was 0.74 (0.64-0.87) p = 0.0002 favoring again apixaban. Standard apixaban dose over reduced dose is less hemorrhagic compared to warfarin. Overall, in our study the risk of thrombosis in both arms was statistically non-different. CONCLUSIONS In our study we observed less hemorrhagic events with apixaban in ESRD patients compared to warfarin.

Abstract
Cardiovascular diseases are highly prevalent among patients on dialysis. For these diseases, antiplatelets and antithrombotic therapies including heparin, vitamin K antagonists, and direct oral anticoagulants, are being used. However, the benefit-risk balance of these therapies could differ for dialysis patients compared with the general population. This review article focuses on the bleeding risk associated with the use of heparin, antiplatelets, vitamin K antagonists, and direct oral anticoagulants in patients receiving hemodialysis.

Abstract
It is well established that direct oral anticoagulants (DOACs) are the cornerstone of anticoagulant strategy in atrial fibrillation (AF) and venous thromboembolism (VTE) and should be preferred over vitamin K antagonists (VKAs) since they are superior or non-inferior to VKAs in reducing thromboembolic risk and are associated with a lower risk of intracranial hemorrhage (IH). In addition, many factors, such as fewer pharmacokinetic interactions and less need for monitoring, contribute to the favor of this therapeutic strategy. Although DOACs represent a more suitable option, several issues should be considered in clinical practice, including drug-drug interactions (DDIs), switching to other antithrombotic therapies, preprocedural and postprocedural periods, and the use in patients with chronic renal and liver failure and in those with cancer. Furthermore, adherence to DOACs appears to remain suboptimal. This narrative review aims to provide a practical guide for DOAC prescription and address challenging scenarios.

Safety and efficacy of apixaban versus low-molecular weight heparin or vitamin-K antagonists for venous thromboembolism treatment in patients with severe renal failure: A systematic review and meta-analysis. Thromb Res 2023; 229:77-85. [PMID: 37419006 DOI: 10.1016/j.thromres.2023.06.027] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2023] [Revised: 06/26/2023] [Accepted: 06/27/2023] [Indexed: 07/09/2023]
Abstract
INTRODUCTION Chronic kidney disease is an independent risk factor for venous thromboembolism (VTE). Traditionally, Low Molecular Weight Heparin (LMWH) followed by warfarin has been the conventional therapy for VTE treatment. Direct oral anticoagulants (DOACs), including apixaban, have shown several advantages over the traditional therapy in individuals with normal kidney function. This meta-analysis aims to review the safety and efficacy of apixaban compared to warfarin or LMWH for the treatment of VTE in severe renal failure. METHOD We conducted literature search in PubMed, Embase, and Cochrane databases. Retrospective observational studies involving clinical effectiveness and safety outcomes of apixaban compared to warfarin in adult patients with an estimated glomerular filtration rate (eGFR) <30 mL/min/m2 or on dialysis were included. RESULTS Eight studies were included in the analysis. Significant reduction in VTE recurrence observed in apixaban compared to warfarin (RR, 0.65; 95 % CI, 0.43-0.98; P = 0.04; I2 = 78 %). No significant difference in all-cause mortality between apixaban and warfarin (RR, 0.99; 95 % CI, 0.91-1.07; P = 0.74; I2 = 0 %). Apixaban showed a significantly lower rate of major bleeding (RR, 0.72; 95 % CI, 0.62-0.84; P < 0.0001; I2 = 34 %) and minor bleeding events (RR, 0.42; 95 % CI, 0.21-0.86; P = 0.02; I2 = 10 %) compared to warfarin. No significant difference observed in clinically relevant non-major bleeding between apixaban and warfarin (RR, 0.81; 95 % CI, 0.65-1.00; P = 0.05; I2 = 67 %). CONCLUSION Apixaban was favored over warfarin for treating VTE in severe renal failure, reducing VTE recurrence and bleeding risk. No differences were observed in all-cause mortality and CRNMB events. More evidence is required due to limited RCTs and prospective studies.

Abstract
INTRODUCTION Evidence suggests that an apixaban-based strategy to treat acute venous thromboembolism (VTE) in patients with End-Stage Kidney Disease (ESKD) may be safer than a warfarin-based strategy. Apixaban has an additional advantage of not requiring bridging with heparin which often necessitates long hospitalizations for patients with ESKD. We sought to determine if an apixaban-based strategy is associated with less healthcare utilization than a warfarin-based strategy. MATERIAL AND METHODS We employed a new-user, active-comparator retrospective cohort study using inverse probability of treatment weights (IPTW) to adjust for confounding demographic and clinical variables. Patients with ESKD newly initiated on either apixaban or warfarin for an acute VTE between 2014 and 2018 in the United States Renal Data System were included. Outcomes were presence of index hospitalization, length of index hospitalization, total hospital days, total hospital days excluding index hospitalization, total emergency department (ED) visits that did not result in hospitalization, and total skilled nursing facility days. RESULTS At six months, patients who received apixaban were less likely to have an index hospitalization, had a shorter index hospitalization (median of 4.0 vs 8.0 days, p < 0.001), and had fewer total hospital days. The IPTW and index year-adjusted incidence rate ratios of total hospital days at one, three, and six months were 0.83 (95 % confidence intervals (CI) 0.79-0.86), 0.84 (95 % CI 0.81-0.88), and 0.88 (95 % CI 0.83-0.92) for apixaban compared to warfarin. CONCLUSION Among patients with ESKD and VTE, resource utilization for an apixaban-based strategy appears to be lower than for a warfarin-based strategy.
