研究设计:

Study design:

Case-Control study 

研究目的:

本研究期望在目前国内外已有的儿童抗凝治疗研究基础上通过回顾性病例对照研究,进一步验证利伐沙班在儿童静脉血栓栓塞性疾病(VTE)中使用的安全性和有效性,以证实对于儿童VTE患者,是否可广泛选择利伐沙班作为抗凝药物,达到提高儿童抗凝治疗疗效、保障抗凝治疗安全性和提高儿童抗凝治疗依从性的目的,并为儿童VTE患者提供更加安全有效的抗凝药物选择。  

Objectives of Study:

This study is expected to further verify the safety and effectiveness of rivaroxaban in children with venous thromboembolic disease (VTE) through retrospective case-control studies on the basis of existing studies on anticoagulant therapy in children at home and abroad, so as to confirm whether rivaroxaban can be widely selected as an anticoagulant for children with VTE, and to achieve the purpose of improving the efficacy of anticoagulant therapy in children, ensuring the safety of anticoagulant therapy and improving the compliance of anticoagulant therapy in children, and to provide more safe and effective anticoagulant drug choices for children with VTE.

药物成份或治疗方案详述:

利伐沙班的给药方案是根据EINSTEIN-Jr的2期和3期研究进行的(针对体重的利伐沙班方案与每天一次服用20mg利伐沙班的年轻人的暴露量相匹配)。 

Description for medicine or protocol of treatment in detail:

Rivaroxaban dosing regimens were carried out according to the EINSTEIN-Jr phase 2 and 3 studies (a rivaroxaban regimen for their bodyweight that matched the exposure in young adults treated with 20 mg rivaroxaban once-daily).  

纳入标准:

①年龄0~18岁; ②临床诊断为VTE(包括深静脉血栓形成和/或肺栓塞等); ③采用国内外诊疗指南推荐的标准抗凝药物或利伐沙班进行抗凝治疗(肝素钠注射液,12500 U/支,上海上药第一生化药业有限公司;低分子肝素钙针(博璞青),6000iu/支,天津红日药业股份有限公司;华法林钠片,2.5mg/片,上海上药信谊药厂有限公司;利伐沙班片(拜瑞妥),10mg/片,Bayer,AG); ④所有病例均完成了至少5天的初始肝素化; ⑤标准抗凝方案组患儿完成初始肝素化后继续使用UFH/LMWH或改用VKA抗凝,其具体给药方案根据药品说明书或国内外抗血栓诊疗指南进行制定; ⑥利伐沙班组患儿在初始肝素化5-9天后使用利伐沙班替代标准抗凝药物进行序贯抗凝治疗,其具体给药方案根据EINSTEIN- Jr 2期和3期临床试验进行制定(因为利伐沙班在中国用于儿童VTE的抗凝治疗属于超说明书用药); ⑦为了避免抗凝药物调整时可能产生的抗凝效果叠加效应,本研究纳入的利伐沙班组儿童均符合停用UFH后4小时或停用低分子肝素后6-12小时开始利伐沙班抗凝治疗的条件,若初始抗凝药物为VKA,则在国际标准化比值(INR)小于2.5后进行抗凝药物调整。

Inclusion criteria

① Age 0~18 years old; ② Clinical diagnosis of VTE (including deep vein thrombosis and/or pulmonary embolism); ③ Standard anticoagulant drugs recommended by domestic and foreign guidelines or rivaroxaban for anticoagulant therapy; ④ All patients completed at least 5 days of initial heparinization; ⑤ Children in the standard anticoagulation program group continued to use UFH/LMWH or changed to VKA anticoagulation after initial heparinization, and the specific administration plan was formulated according to the drug labels or domestic and foreign antithrombotic diagnosis and treatment guidelines; ⑥ 5 to 9 days after initial heparinization, children in the rivaroxaban group were given sequential anticoagulant therapy with rivaroxaban instead of standard anticoagulant drugs, and the specific administration regimen was developed according to EINSTEIN-Jr phase Ⅱ and phase Ⅲ clinical trials (because rivaroxaban anticoagulant therapy for VTE in children in China is off-label drug use); ⑦ In order to avoid the additive effect of anticoagulant effect that may occur when anticoagulant drugs are adjusted, the children in the rivaroxaban group included in this study all met the conditions of starting rivaroxaban anticoagulant therapy 4 hours after stopping UFH or 6-12 hours after stopping low molecular weight heparin. If the initial anticoagulant drug is VKA, The anticoagulant drug is adjusted after the International standardized ratio (INR) is less than 2.5.

排除标准:

①活动性出血; ②有原发性凝血功能障碍基础疾病(如血栓性血小板减少症(thrombotic thrombocytopenia , TTP)); ③具有出血高危风险或抗凝治疗禁忌症; ④肾小球滤过率小于30mL/min/1.73m2; ⑤血小板计数小于50×10∧9/L; ⑥基础疾病或其他原因导致患儿的临床预期寿命小于3个月; ⑦静脉血栓栓塞采用特殊方法治疗(如溶栓、射频消融和手术取栓等); ⑧合并使用其他可引起出血、凝血或改变患儿凝血功能水平的药物; ⑨利伐沙班组给药方案不符合EINSTEIN- Jr临床试验(按体重折算成人等效剂量),标准抗凝方案组给药方案不符合药品说明书或临床诊疗指南; ⑩抗凝药物的生产厂家、规格不符合纳入标准;临床资料不完整,抗凝治疗完成后时间不足1年,因死亡等不可抗拒因素导致治疗中断或无法完成随访的儿童VTE患者。

Exclusion criteria:

① Active bleeding; ② Basic diseases of primary coagulation dysfunction (such as thrombotic thrombocytopenia (TTP)); ③ Have a high risk of bleeding or contraindications to anticoagulation therapy; ④ The glomerular filtration rate is less than 30mL/min/1.73m2; ⑤ Platelet count less than 50×10∧9/L; ⑥The clinical life expectancy of children with underlying diseases or other reasons is less than 3 months; ⑦Venous thromboembolism is treated with special methods (such as thrombolysis, radiofrequency ablation and surgical thrombolysis, etc.); ⑧ Combined use of other drugs that can cause bleeding, clotting or change the level of clotting function in the child; ⑨ The administration regimen of rivaroxaban group did not conform to the EINSTEIN-Jr clinical trial (adult equivalent dose based on body weight), and the administration regimen of standard anticoagulation regimen group did not conform to the drug labels or clinical guidelines; ⑩ The manufacturers and specifications of anticoagulant drugs do not meet the inclusion criteria; Pediatric VTE patients with incomplete clinical data, less than 1 year after completion of anticoagulation therapy, and interruption of treatment or inability to complete follow-up due to irresistible factors such as death.
