OBJECTIVE
Currently, corticosteroids are widely used to treat coronavirus disease 2019 (COVID-19) symptoms. However, the therapeutic role of corticosteroids remains highly controversial. To that end, we aimed to assess the efficacy of corticosteroids in treating COVID-19 patients.
METHOD
We searched PubMed, Embase, and Cochrane Library to select suitable studies. Our primary study endpoint was all-cause mortality. The secondary study endpoint was the length of hospital stay.
RESULTS
A total of 9 randomized controlled trials (RCTs) with 7907 patients were assessed. The pooled result indicated that corticosteroids treatment could significantly reduce all-cause mortality in patients with COVID-19 (RR = 0.88, 95% CI [0.82, 0.95], = 0.002). When subgroup analyses were performed, we found that corticosteroids were associated with decreased all-cause mortality in severe COVID-19 patients (RR = 0.77, 95% CI [0.68, 0.88], < 0.0001), however no obvious difference was observed in all-cause mortality of non-severe COVID-19 patients between the corticosteroid and control group (RR = 0.96, 95% CI [0.86, 1.06], = 0.41), meanwhile, a low dose (RR = 0.89, 95% CI [0.82, 0.97], = 0.007) of dexamethasone (RR = 0.9, 95% CI [0.83, 0.98], = 0.01) with a long treatment course (RR = 0.89, 95% CI [0.82, 0.98], = 0.02) was beneficial for all-cause mortality in COVID-19 patients. Additionally, we found that corticosteroids might be associated with a longer length of hospital stay in non-severe COVID-19 patients (MD = 3.83, 95% CI [1.11, 6.56], = 0.006).
CONCLUSION
Our results showed that corticosteroid therapy was related to a reduction in all-cause mortality in severe COVID-19 patients. However, in patients with non-severe COVID-19, the use of corticosteroids did not decrease all-cause mortality and may prolong the duration of hospital stay. In addition, we revealed that a low dose of dexamethasone with a long treatment course could reduce all-cause mortality in COVID-19 patients.
目的
目前，皮质类固醇被广泛用于治疗2019冠状病毒病（COVID-19）症状。然而，皮质类固醇的治疗作用仍存在高度争议。为此，我们旨在评估皮质类固醇治疗COVID-19患者的疗效。
方法
我们检索了PubMed、Embase和Cochrane图书馆以选择合适的研究。我们的主要研究终点是全因死亡率。次要研究终点是住院时间。
结果
共评估了9项随机对照试验（RCT），涉及7907例患者。汇总结果表明，皮质类固醇治疗可显著降低COVID-19患者的全因死亡率（RR = 0.88，95%CI [0.82，0.95]，P = 0.002）。进行亚组分析时，我们发现皮质类固醇与重症COVID-19患者全因死亡率降低相关（RR = 0.77，95%CI [0.68，0.88]，P < 0.0001），然而，皮质类固醇组与对照组相比，非重症COVID-19患者的全因死亡率无明显差异（RR = 0.96，95%CI [0.86，1.06]，P = 0.41），同时，低剂量（RR = 0.89，95%CI [0.82，0.97]，P = 0.007）的地塞米松（RR = 0.9，95%CI [0.83，0.98]，P = 0.01）和长疗程治疗（RR = 0.89，95%CI [0.82，0.98]，P = 0.02）对COVID-19患者的全因死亡率有益。此外，我们发现皮质类固醇可能与非重症COVID-19患者住院时间延长有关（MD = 3.83，95%CI [1.11，6.56]，P = 0.006）。
结论
我们的结果表明，皮质类固醇治疗与重症COVID-19患者全因死亡率降低有关。然而，在非重症COVID-19患者中，使用皮质类固醇并未降低全因死亡率，且可能延长住院时间。此外，我们发现低剂量地塞米松长疗程治疗可降低COVID-19患者的全因死亡率。
