For over 40 years, systemic corticosteroids have been a mainstay of treatment for patients with exacerbations of chronic obstructive pulmonary disease (COPD). Surprisingly, the optimal dosage of corticosteroids is unknown in critically ill patients requiring assisted ventilation, a group with high morbidity and mortality. We surveyed 39 academic physicians within the United States Critical Illness and Injury Trials Group (USCIITG) and the Prevention and Early Treatment of Acute Lung Injury Trials Network (PETAL) to determine the range of corticosteroid dosages used to treat patients with COPD exacerbations requiring assisted ventilation. We also asked if these physicians believe that a clinical trial is needed to determine the optimal dosage of corticosteroids in this population. Thirty-two physicians (82%) responded to the survey. Usual practice was to start intravenous methylprednisolone at a median dose of 120 mg/day (range 40-500 mg/day). In the context of a clinical trial, 78% of physicians were comfortable initiating methylprednisolone at a dose as low as 40 mg/day. In contrast, physicians were split on the highest acceptable methylprednisolone dose, with 44% comfortable initiating doses as high as 500 mg/day, 44% at 240 mg/day, and 12% at doses less than 240 mg/day. Ninety-four percent of respondents believed that a randomized controlled trial is needed to determine the optimal corticosteroid dose to treat patients with COPD exacerbations requiring assisted ventilation. These results demonstrate sufficient clinical equipoise to support the conduct of a clinical trial to identify the optimal dose of systemic corticosteroids for patients with COPD exacerbations requiring assisted ventilation.
40多年来,全身用皮质类固醇一直是慢性阻塞性肺疾病(COPD)加重患者的主要治疗手段。令人惊讶的是,对于需要辅助通气的重症患者(这是一个发病率和死亡率都很高的群体),皮质类固醇的最佳剂量尚不清楚。我们对美国重症与损伤试验组(USCIITG)和急性肺损伤预防与早期治疗试验网络(PETAL)的39名学术医生进行了调查,以确定用于治疗需要辅助通气的COPD加重患者的皮质类固醇剂量范围。我们还询问这些医生是否认为需要进行一项临床试验来确定该人群中皮质类固醇的最佳剂量。32名医生(82%)回复了调查。通常的做法是开始静脉注射甲泼尼龙,中位剂量为120毫克/天(范围为40 - 500毫克/天)。在临床试验的背景下,78%的医生愿意以低至40毫克/天的剂量开始使用甲泼尼龙。相比之下,医生们对甲泼尼龙的最高可接受剂量存在分歧,44%的医生愿意开始使用高达500毫克/天的剂量,44%的医生愿意使用240毫克/天的剂量,12%的医生愿意使用低于240毫克/天的剂量。94%的受访者认为需要进行一项随机对照试验来确定治疗需要辅助通气的COPD加重患者的最佳皮质类固醇剂量。这些结果表明,有足够的临床平衡来支持开展一项临床试验,以确定需要辅助通气的COPD加重患者全身用皮质类固醇的最佳剂量。
