Systemic corticosteroids for the treatment of COPD exacerbations decrease treatment failure and shorten the length of hospitalization. However, the optimal dose is unclear.
Is personalized-dose corticosteroid administered according to a dosing scale more effective than fixed-dose corticosteroid administration in hospitalized patients with COPD with exacerbations?
This was a prospective, randomized, open-label trial. In-hospital patients with COPD with exacerbations were randomly assigned at a 1:1 ratio to either the fixed-dose group (receiving the equivalent of 40 mg of prednisolone) or the personalized-dose group for 5 days. The primary end point was a composite measure of treatment failure that included in-hospital treatment failure and medium-term (postdischarge) failure. Secondary end points were length of stay and cost.
A total of 248 patients were randomly assigned to the fixed-dose group (n = 124) or personalized-dose group (n = 124). One patient in each group was not included in the intention-to-treat population because of incorrect initial COPD diagnosis. Failure of therapy occurred in 27.6% in the personalized-dose group, compared with 48.8% in the fixed-dose group (relative risk, 0.40; 95% CI, 0.24-0.68; P = .001). The in-hospital failure of therapy was significantly lower in the personalized-dose group (10.6% vs 24.4%; P = .005), whereas the medium-term failure rate, adverse event rate, hospital length of stay, and costs were similar between the two groups. After treatment failure, a lower additional dose of corticosteroids and a shorter duration of treatment were needed in the personalized-dose group to achieve control of the exacerbation. In the personalized-dose cohort, those receiving 40 mg or less had an average failure rate of 44.4%, compared with 22.9% among those receiving more than 40 mg (P = .027).
Personalized dosing of corticosteroids reduces the risk of failure because more patients were provided with a higher initial dose, especially > 60 mg, whereas 40 mg or less was too low in either group.

全身皮质类固醇治疗 COPD 加重可降低治疗失败率并缩短住院时间。然而,最佳剂量尚不清楚。
根据剂量表给予个体化剂量皮质类固醇是否比固定剂量皮质类固醇治疗 COPD 加重的住院患者更有效?
这是一项前瞻性、随机、开放标签试验。将住院的 COPD 加重患者按 1:1 的比例随机分配至固定剂量组(接受相当于 40mg 泼尼松龙)或个体化剂量组,治疗 5 天。主要终点是治疗失败的综合指标,包括住院治疗失败和中期(出院后)失败。次要终点是住院时间和成本。
共有 248 例患者被随机分配至固定剂量组(n=124)或个体化剂量组(n=124)。由于初始 COPD 诊断错误,每组各有 1 例患者未纳入意向治疗人群。个体化剂量组治疗失败的发生率为 27.6%,而固定剂量组为 48.8%(相对风险,0.40;95%CI,0.24-0.68;P=0.001)。个体化剂量组住院治疗失败显著降低(10.6% vs 24.4%;P=0.005),而两组的中期失败率、不良事件发生率、住院时间和成本相似。治疗失败后,个体化剂量组需要较低的皮质类固醇附加剂量和较短的治疗时间来控制加重。在个体化剂量组中,接受 40mg 或以下剂量的患者平均失败率为 44.4%,而接受 40mg 以上剂量的患者失败率为 22.9%(P=0.027)。
皮质类固醇的个体化剂量可降低失败风险,因为为更多患者提供了更高的初始剂量,尤其是>60mg,而两组中 40mg 或以下的剂量都太低。
