BACKGROUND Increased numbers of blood and sputum eosinophils are associated with higher exacerbation frequency and increased asthma severity. In clinical trials, targeting Interleukin-5 has been shown to be a useful therapeutic strategy for patients with severe eosinophilic asthma. METHODS Twenty-six patients have been commenced on Reslizumab in our institution since early 2017. Safety and clinical efficacy parameters were recorded at regular intervals. RESULTS Mean ACQ-6 score at the start of treatment was 3.5. The average number of exacerbations in the year preceding treatment was 8.3 per person. 30% of patients had been admitted to hospital at least once over the 12 months preceding therapy. 54% of our patients were on long term oral steroid. Our data showed sustained improvement of Asthma control (Mean improvement in ACQ-6 was 1.7 at 1 year, and 2.0 at 2 years, P = 0.0001). Of the patients who were on long term systemic steroids, 35.7% discontinued steroids completely, with a mean reduction of prednisolone dose of 5.2 mg at 1 year. There was a 79% reduction in the annual exacerbation frequency at 1 year, and 88% at 2 years (P = < 0.0001). Modest, albeit statistically significant increases in creatine kinase which seemed to plateau by 1 year were noted. CONCLUSIONS Overall, Reslizumab was well tolerated with discontinuation of treatment due to side effects recorded in only one patient. Our data confirm the utility of anti-IL5 therapy in a carefully selected phenotype of severe asthma with evidence of eosinophilic airway inflammation.

Reslizumab在重度哮喘治疗中的有效性:真实经验。

背景技术血液和痰中嗜酸性粒细胞数量的增加与发作频率增加和哮喘严重程度增加有关。在临床试验中,针对严重嗜酸性粒细胞性哮喘的患者,靶向白介素-5已被证明是一种有用的治疗策略。方法自2017年初以来,本院已有26例患者开始接受Reslizumab治疗。定期记录安全性和临床疗效参数。结果治疗开始时的平均ACQ-6评分为3.5。治疗前一年的平均加重次数为每人8.3。在治疗前的12个月中,有30%的患者至少入院一次。我们的患者中有54%长期服用类固醇激素。我们的数据显示,哮喘控制得到了持续改善(ACQ-6在1年时的平均改善为1.7,和2年时的2.0,P = 0.0001)。在长期接受全身性类固醇激素治疗的患者中,有35.7%的患者完全停用了类固醇激素,泼尼松龙在1年时的平均剂量减少了5.2 mg。1年的年急性发作频率降低了79%,而2年的年急性发作频率降低了88%(P = <0.0001)。值得注意的是,尽管肌酸激酶在统计学上有显着增加,但似乎在1年之前达到了平稳水平。结论总体而言,由于仅一名患者记录了副作用,因此瑞利珠单抗耐受性良好,可以中断治疗。我们的数据证实了抗IL5疗法在认真选择的严重哮喘表型中的实用性,并有嗜酸性气道炎症的证据。1年时泼尼松龙的平均剂量减少5.2 mg。1年的年急性发作频率降低了79%,而2年的年急性发作频率降低了88%(P = <0.0001)。值得注意的是,尽管肌酸激酶在统计学上有显着增加,但似乎在1年之前达到了平稳水平。结论总体而言,由于仅一名患者记录了副作用,因此瑞利珠单抗耐受性良好,可以中断治疗。我们的数据证实了抗IL5疗法在认真选择的严重哮喘表型中的实用性,并有嗜酸性气道炎症的证据。1年时泼尼松龙的平均剂量减少5.2 mg。1年的年急性发作频率降低了79%,而2年的年急性发作频率降低了88%(P = <0.0001)。值得注意的是,尽管肌酸激酶在统计学上有显着增加,但似乎在1年之前达到了平稳水平。结论总体而言,由于仅一名患者记录了副作用,因此瑞利珠单抗耐受性良好,可以中断治疗。我们的数据证实了抗IL5疗法在认真选择的严重哮喘表型中的实用性,并有嗜酸性气道炎症的证据。结论总体而言,由于仅一名患者记录了副作用,因此瑞利珠单抗耐受性良好,可以中断治疗。我们的数据证实了抗IL5疗法在认真选择的严重哮喘表型中的实用性,并有嗜酸性气道炎症的证据。结论总体而言,由于仅一名患者记录到了副作用,因此瑞利珠单抗耐受性良好,中断了治疗。我们的数据证实了抗IL5疗法在认真选择的严重哮喘表型中的实用性,并有嗜酸性气道炎症的证据。
