Popis: Background Acute respiratory distress syndrome (ARDS), are respiratory diseases with high morbidity and mortality. Clinical trials investigating the efficacy of corticosteroids in the treatment of ARDS often yield contradictory results. We hereby conducted a systematic review and meta-analysis to investigate the efficacy of corticosteroids in ARDS management.Materials and Methods We conducted a search for randomized clinical trials (RCT) and observational studies that utilized corticosteroids for patients with ARDS in Web of Science, PubMed, and Embase. The primary outcome was mortality. Risk of bias was assessed using Cochrane or NOS scales. Statistical effect size was analyzed using the Mantel-Haenszel method.Results A total of 20 studies, comprising 11 observational studies and 9 RCTs, were eligible for analysis. In RCTs, corticosteroids were associated with a reduction of mortality in ARDS patients (relative risk [RR] = 0.80, 95%CI: 0.71-0.91, p = 0.001). Further subgroup analysis indicated that specific variables, such as low-dose (RR = 0.81; 95%CI: 0.67-0.98; p = 0.034), methylprednisolone (RR = 0.70; 95%CI: 0.49-0.98; p = 0.035), and dexamethasone (RR = 0.82; 95%CI: 0.69-0.98; p = 0.029) were associated with mortality among patients receiving corticosteroids. However, in observational studies, corticosteroids increased the risk of death (RR = 1.16, 95%CI: 1.04-1.29; p = 0.001). Subgroup analysis showed that the use of high-dose corticosteroids was associated with higher patient mortality (RR = 1.20; 95%CI: 1.04-1.38; p = 0.001).Conclusions The efficacy of corticosteroids on the mortality of ARDS differed by the type and dosage of corticosteroids used, as well as the etiologies. Current data do not support routine use of corticosteroids in ARDS since protective effects were observed in RCTs but increased mortality was found in observational studies. More well designed and large clinical trials are needed to specify the favorable subgroups for corticosteroid therapy.
