2017年12月,发表在《Arthritis Rheumatol》的一项由新西兰、英国和美国科学家进行的随机、双盲、安慰剂对照研究,考察了非布司他对早期痛风的作用。

目的:评价非布司他治疗vs安慰剂对早期痛风(1或2个痛风耀斑)的高尿酸血症患者关节损伤的影响。

方法:在这项双盲、安慰剂对照研究中,314例高尿酸血症(血清尿酸[UA]水平≥7.0 mg/dl)伴早期痛风的受试者被随机(1:1)分配至非布司他40 mg每日1次组(如果第14天血清UA水平≥6.0 mg/dl,则增加至80 mg)或安慰剂组。主要疗效终点为基线至24个月单个受累关节的修正Sharp/van der Heijde磨损评分的平均变化。额外疗效终点包括基线至24个月单个受累关节滑膜炎、磨损和水肿的类风湿关节炎磁共振成像评分(RAMRIS)的得分的变化,以及痛风耀斑发生率和血清UA水平。评价研究期间的安全性。

结果:经过2年非布司他治疗,关节磨损没有显着改变。两组从基线至24个月单个受累关节的修正Sharp/van der Heijde磨损评分的平均变化较小,没有组间差异。然而,与安慰剂相比,非布司他治疗显着改善了24个月时的RAMRIS磨损评分(自基线的变化 -0.43 vs -0.07;P<0.001),降低了痛风耀斑的总发生率(29.3% vs 41.4%;P<0.05),并改善血清UA控制(62.8% vs 5.7%;P<0.001)。未报告重大安全性问题。

结论:非布司他降尿酸疗法改善了早期痛风患者由核磁共振成像确定的关节磨损,并降低了痛风耀斑的发生率。

现代基因检测技术已经可以发现个体对不同药物的耐受和代谢程度,从而可以避免“一针致聋”等药物严重不良反应。2017年10月,发表在《Rheumatology (Oxford).》的一项研究调查了痛风患者开始别嘌醇治疗前进行HLA-B * 58:01基因分型检测是否具有成本效果。结果表明,为了降低被处方别嘌呤醇治疗的痛风患者的药物不良反应发生率,HLA-B*58:01常规检测不太可能具有成本效果。
