ABSTRACT
INTRODUCTION: Steroids have shown its usefulness in critically ill COVID-19 patients. However, the time of starting steroid and dose tailored to severity remain a matter of inquiry due to still emerging evidences and wide-ranging concerns of benefits and harms. We did a retrospective record analysis in an apex teaching hospital ICU setting to explore optimal doses and duration of steroid therapy which can decrease mortality. METHODOLOGY: 114 adults with COVID-19-ARDS admitted to ICU between 20thMarch-15thAugust2020 were included in chart review. We did preliminary exploratory analysis (rooted in steroid therapy matrix categorized by dose and duration) to understand the effect of several covariates on survival. This was followed by univariate and multivariate Cox proportion hazard regression analysis and model diagnostics. RESULTS: Exploratory analysis and visualization indicated age, optimal steroid, severity (measured in P/F) of disease and infection status as potential covariates for survival. Univariate cox regression analysis showed significant positive association of age>60 years{2.6 (1.5-4.7)} and protective effect of optimum steroid{0.38(0.2-0.72)} on death (hazard) in critically ill patients. Multivariate cox regression analysis after adjusting effect of age showed protective effect of optimum steroid on hazard defined as death {0.46(0.23-0.87),LR=17.04,(p=2e-04)}.The concordance was 0.70 and model diagnostics fulfilled the assumption criteria for proportional hazard model. CONCLUSION: Optimal dose steroid as per defined 'optimum' (<24 hours and doses tailored to P/F at presentation) criteria can offer protective effect from mortality which persists after adjusting for age. This protective effect was not found to be negatively influenced by the risk of infection.
ABSTRACT
Background: Corticosteroids have attracted attention as a treatment option for severe Coronavirus disease (COVID-19). However, published data on steroid therapy is debatable, and real-world data is lacking. This study evaluated the effect of treatment regimens, especially Pulse steroid therapy (Injection Methyl Prednisolone 250 mg iv once a day for three days) in severe-COVID-19 pneumonia at an Indian tertiary care hospital. Methods: This observational cross-sectional study included severe COVID-19 pneumonia patients aged >18 years, requiring assisted ventilation. As part of the hospital protocol, patients received either pulse steroid therapy, remdesivir or tocilizumab in addition to the recommended steroid doses i.e., injection of dexamethasone 6 mg iv once a day. The association of factors and treatment regimens to patient outcomes was evaluated. Results: Data of eighty-three patients were assessed, majority being above 60 years (n = 30, 36.14%) and males (n = 45/83, 54.21%). The commonest comorbidities were hypertension (n = 26), diabetes (n = 23) and obesity (n = 19), fifty-five patients (66.26%) reported at least one comorbidity. Sixty-one patients (73.49%) had received pulse steroid regimen, forty-eight patients (57.83%) were administered remdesivir-based regimen while twelve patients (14.46%) had received tocilizumab treatment. 54.1% patients managed with pulse steroid regimens were discharged after treatment, statistically similar to remdesivir-managed subgroup (62.5%, p > 0.05). On sub-group analysis, pulse steroids showed better outcomes in young males with no comorbidities. No comorbidity had significant relationship with patient outcomes (p > 0.05). Conclusion: Pulse steroid therapy is an effective therapy in management of patients with severe COVID-19 pneumonia in a real-world setting, with better outcomes in young males without comorbidities. Pulse steroids can be considered a viable option for severe-COVID-19 pneumonia management.
