To obtain high-versus low-doses of corticosteroids, which exposes the analysis to remedy assignment bias. Weaddress this concern by comparing baseline traits inside the 2 groups and located that they have been effectively matched. Tocilizumab was administered to patients in the discretion of the treating physicians, and individuals inside the low-dose group had been much more likely to acquire tocilizumab. Many with the patients had been treated ahead of society suggestions included tocilizumab in their remedy algorithm. In addition, tocilizumab includes a larger acquisition price than dexamethasone and its availability might have been impacted by drug shortages in the course of this time. All these elements could have impacted the outcomes that we analyzed in this study. Despite this, we believe that the outcomes are notable inside the absence of appropriately randomized dose inding trials that examine the use of corticosteroids in COVID-19 ARDS.Conclusion and RelevanceIn critically ill sufferers with COVID-19 ARDS requiring mechanical ventilation, our study found no variations in survival to discharge among individuals who received highversus low-dose corticosteroids. Our study suggests that there was no benefit of high-dose corticosteroids with out tocilizumab compared with low-dose corticosteroids with tocilizumab but there’s signal that each can increase outcomes more than low-dose corticosteroids alone. Our findings are compatible with existing NIH treatment guidelines for sufferers with COVID-19 ARDS requiring mechanical ventilation, which advise dexamethasone 6 mg per day (low dose) for ten days plus tocilizumab. Future potential research are necessary to identify the optimal dose of corticosteroids within this patient population.
