ODSR:秋水仙素治疗急性痛风的方案比较。

2021-10-31 从医路漫漫 MedSci原创

痛风是一种非常常见的引起炎症性关节炎的原因(疼痛,红肿,发热和受影响的关节肿胀),是由在关节内或关节周围形成的尿酸盐晶体引起的。

背景:痛风是一种非常常见的引起炎症性关节炎的原因(疼痛,红肿,发热和受影响的关节肿胀),是由在关节内或关节周围形成的尿酸盐晶体引起的。尿酸是一种体内正常产生的废物,通常随尿液排出。然而,在痛风的情况下,要么是过量生产尿酸,要么是身体不能迅速排泄它,或者是两者都有。痛风的发作通常发生迅速,通常在7至10天内消退。秋水仙碱是一种药物,主要用于治疗痛风急性发作或预防发作,同时可以降低尿酸。尽管秋水仙碱作为治疗急性痛风的一线疗法之一,其益处和危害的证据是相对有限的。

目的:了解秋水仙碱治疗急性痛风的利弊。

搜索方法:我们更新了CENTER、MEDLINE、EMBASE、ClinicalTrials.gov和世卫组织ICTRP注册中心的搜索至2020年8月28日。我们在搜索中没有施加任何日期或语言限制。

选择标准:我们考虑了已发表的随机对照试验(RCT)和准随机对照试验(准RCT),评估秋水仙碱治疗与其他治疗(安慰剂或其他有效治疗方法)在急性痛风中的疗效,低剂量秋水仙碱与安慰剂的临床相关剂量比较为主要比较。主要结果为疼痛、参与者对治疗成功的整体评估(从基线到32小时至36小时疼痛减少50%或以上的比例)、炎症减少、相关关节功能、严重不良事件、总不良事件和因不良事件而停药。

数据收集和分析:我们使用了Cochrane所期望的标准方法学程序进行收集资料。

主要结果:在这篇最新的综述中,我们纳入了四项试验(803名随机参与者),其中包括两项新的试验。一项三组试验比较了高剂量秋水仙碱(52名参与者)、低剂量秋水仙碱(74名参与者)和安慰剂(59名参与者);一项试验将高剂量秋水仙碱与安慰剂进行了比较(43名参与者);一项试验将低剂量秋水仙碱与非甾体抗炎药(NSAIDs)进行了比较(399名参与者);以及一项试验将低剂量秋水仙碱与川胡抗痛风混合物(中药复方)进行了比较(176名参与者)。我们没有发现任何将秋水仙碱与糖皮质激素进行比较的试验(通过任何途径)。

参与者的平均年龄从51.2岁到70岁,试验持续时间从48小时到12周。两项试验的偏倚风险较低,一项试验可能易受选择偏倚(随机序列产生)、报告偏倚和其他偏倚的影响,而另一项开放标签试验的表现和检测偏倚风险较高。

对于初步比较,来自一项试验(103名参与者,因不精确和偏见而被降级)的低质量证据表明,与安慰剂相比,低剂量秋水仙碱可能会改善治疗结果不良事件的风险很小或没有增加在32到36小时内报告治疗成功(50%或更多疼痛减轻)的人数,使用低剂量秋水仙碱的人数(418/1000)略高于安慰剂(172/1000;风险比(RR)2.43,95%可信区间(CI)1.05-5.64;25%报告绝对成功改善(增加7%到42%,95%CI包含临床上重要和不重要的益处);143%报告治疗相对变化成功(增加5%到464%。低剂量秋水仙碱的总不良事件发生率为364/1000,而安慰剂组为276/1000:RR为1.32,95%CI为0.68~2.56;绝对差异为9%,低剂量秋水仙碱治疗的事件增加9%(减少9%至43%,95%的顺式作用包括临床重要影响和无影响);相对变化增加32%(减少32%至增加156%)。没有参与者因不良事件而退出,也没有报告任何严重的不良事件。没有疼痛、炎症和功能的报道。

   来自两个试验(124名参与者)的低质量证据(由于不精确和偏见而被降级)表明,与安慰剂相比,大剂量秋水仙碱可能会改善症状,但会增加有害的风险。更多的参与者报告说,与安慰剂(240/1000)相比,大剂量秋水仙碱在32至36小时内治疗成功(518/1000):RR 2.16,95%CI 1.28至3.65,绝对改善28%(增加8%至46%);与安慰剂(48/1000)相比,更多的参与者在此时间点也减轻了炎症(504/1000):RR 10.50,95%CI 1.48至74.38;绝对改善45%(比。但大剂量秋水仙碱的不良事件报告更多(829/1000比260/1000):RR 3.21,95%CI 2.01至5.11,绝对差异57%(多26%至74%)。没有疼痛和功能的报道。

   一项比较高剂量秋水仙碱和低剂量秋水仙碱的单一试验的低质量证据表明,在32至36小时的治疗成功率方面,益处可能几乎没有差异,但更高剂量相关的不良事件更多。同样,来自单一试验的低质量证据表明,在治疗成功和7天疼痛减轻方面,低剂量秋水仙碱与非甾体抗炎药相比也可能只有很少或没有益处,在4周随访中报告了类似数量的不良事件。在这两项试验中,炎症的减少、靶关节的功能和不良事件导致的停药均未见报道,而在高剂量与低剂量秋水仙碱试验中,疼痛也未见报道。

由于在试验中报道的严重不良事件很少,因此我们无法在大多数比较中估计严重不良事件的风险。一项试验(399名参与者)报告了三例严重不良反应(一名接受低剂量秋水仙碱的参与者和两名接受非甾体抗炎药的参与者),原因与试验无关(低质量证据因偏倚和不精确而降级) 。

表1 低剂量秋水仙碱与安慰剂治疗急性痛风

表2 高剂量秋水仙碱与安慰剂治疗急性痛风

表3 高剂量秋水仙碱与低剂量秋水仙碱对急性痛风的疗效比较

表4 低剂量秋水仙碱与非甾体抗炎药疗效比较

结论:我们发现,与安慰剂相比,低质量的证据表明,低剂量秋水仙碱可能是急性痛风的有效治疗,它的益处可能与非甾体抗炎药类似。我们降低了证据的偏见和不精确性。与安慰剂相比,高剂量和低剂量秋水仙碱都能改善疼痛,低质量证据表明,与安慰剂相比,高剂量(而不是低剂量)秋水仙碱可能增加不良事件的数量,而低质量证据表明,不良事件的数量可能在低剂量秋水仙碱和NSAIDs相似。 目前还没有试验报道秋水仙碱对有合并症人群的影响,或与糖皮质激素等其他常用治疗方法进行比较。

Ann Rheum Dis:秋水仙素或可降低心血管事件风险

秋水仙素可能对心血管患者有益,但关于痛风患者的心血管事件研究数据稀少,本研究旨在评估痛风患者使用秋水仙素后的心血管事件发生率及全因死亡率。 研究人员分析了来自2006-2011年电子病例(EMR)数据库以及医疗索赔数据库的501名新用秋水仙素的痛风患者,并随访约16.5个月。使用秋水仙素组中有28名发生心血管事件,对照组中82名发生心血管事件,事件发生率分别为35.6/1000人年和81.8/1
