Treatment with 3-day methylprednisolone pulses in severe cases of COVID-19 compared with the standard regimen protocol of dexamethasone

The role of methylprednisolone in severe COVID-19 patients: a meta-analysis

Background

The purpose of this study is to assess the effectiveness of methylprednisolone in severe COVID-19.

Methods

PubMed, the Cochrane Library and Web of Science were searched for literatures comparing methylprednisolone and control treatment in severe COVID-19 patients. Statistical pooling was reported as risk ratio (RR) with corresponding 95% confidence interval (CI). The outcomes of interest in the literature survey were mortality and adverse events.

Results

A total of 13 studies were included, including 3,138 patients with severe COVID-19, of which 1,634 patients were treated with methylprednisolone and 1,504 patients were treated with control treatment. Five of the 13 studies reported severe adverse events. Our meta-analysis indicates that methylprednisolone treatment in COVID-19 patients is associated with a significant reduction in mortality (RR 0.62, 95% CI 0.46-0.85, p = 0.003) compared to control treatment, without an increased risk of adverse events (RR 1.20, 95% CI 0.92-1.56, p = 0.17). Moreover, high-dose methylprednisolone treatment (RR 0.57; 95% CI 0.40-0.82, p = 0.003) and short-course methylprednisolone treatment (RR 0.54; 95% CI 0.38-0.89, p = 0.01) found to significantly reduce mortality. Additionally, it was found that younger severe COVID-19 patients (RR 0.40; 95% CI 0.20-0.80, p = 0.01) had better outcomes to methylprednisolone than older patients.

Conclusion

Methylprednisolone was correlated with lower mortality compared with control treatment in severe COVID-19 patients without increasing serious adverse reactions. Furthermore, high-doses and short-term of methylprednisolone treatment were linked with better younger COVID-19 reported higher benefit from methylprednisolone than older COVID-19 patients.

Long-term outcomes, residual symptoms and quality of life in COVID-19 hospitalized patients: A 12-month longitudinal study

The long-term impact of the coronavirus disease 2019 (COVID-19) pandemic is a critical public health concern. The presence of residual symptoms in COVID-19 survivors has been investigated with various results; however, there is limited data documenting outcomes longer than 6 months post-hospitalization. We aimed to investigate the 12-month lasting effects of COVID-19 in hospitalized patients. From October 2020 through March 2021, 92 patients were enrolled. At admission and 1, 3, 6, and 12 months post-hospitalization, demographic, clinical, laboratory and imaging data, and echocardiography and spirometry test results were recorded. Possible cognitive and functional impairment, as well as the quality of life (QoL), were also assessed. In our cohort (median age: 61 years), 31.5% had severe disease at admission, which correlated with worse laboratory findings and a longer hospital stay (p < 0.001). Inflammatory markers were associated with severity initially, but reverted to normal after 3 months. In total, 55%, 37%, 19%, and 15.5% of patients reported at least one persistent symptom in months 1, 3, 6, and 12, respectively, while "brain fog" persisted up to 12 months in 10% of patients. Spirometry and echocardiography tests returned to normal in most patients during the evaluation, and no one had substantial residual disease. Our study provides insight into the long-term effects of COVID-19 on patients' physical and mental health. Despite the lack of significant residual disease or major complications after a year of thorough follow-up, COVID-19 survivors experienced lasting symptoms and a negative impact on their QoL.

A systematic review and meta-analysis of glucocorticoids treatment in severe COVID-19: methylprednisolone versus dexamethasone

OBJECTIVE

The preferred agent of glucocorticoids in the treatment of patients with severe COVID-19 is still controversial. This study aimed to compare the efficacy and safety of methylprednisolone and dexamethasone in the treatment of patients with severe COVID-19.

METHODS

By searching the electronic literature database including PubMed, Cochrane Central Register of Controlled Trials, and Web of Science, the clinical studies comparing methylprednisolone and dexamethasone in the treatment of severe COVID-19 were selected according to the inclusion criteria and exclusion criteria. Relevant data were extracted and literature quality was assessed. The primary outcome was short-term mortality. The secondary outcomes were the rates of ICU admission and mechanical ventilation, PaO₂/FiO₂ ratio, plasma levels of C-reactive protein (CRP), ferritin, and neutrophil/lymphocyte ratio, hospital stay, and the incidence of severe adverse events. Statistical pooling applied the fixed or random effects model and reported as risk ratio (RR) or mean difference (MD) with the corresponding 95% confidence interval (CI). Meta-analysis was performed using Review Manager 5.1.0.

RESULTS

Twelve clinical studies were eligible, including three randomized controlled trials (RCTs) and nine non-RCTs. A total of 2506 patients with COVID-19 were analyzed, of which 1242 (49.6%) received methylprednisolone and 1264 (50.4%) received dexamethasone treatment. In general, the heterogeneity across studies was significant, and the equivalent doses of methylprednisolone were higher than that of dexamethasone. Our meta-analysis showed that methylprednisolone treatment in severe COVID-19 patients was related to significantly reduced plasma ferritin and neutrophil/lymphocyte ratio compared with dexamethasone, and that no significant difference in other clinical outcomes between the two groups was found. However, subgroup analyses of RCTs demonstrated that methylprednisolone treatment was associated with reduced short-term mortality, and decreased CRP level compared with dexamethasone. Moreover, subgroup analyses observed that severe COVID-19 patients treated with a moderate dose (2 mg/kg/day) of methylprednisolone were related to a better prognosis than those treated with dexamethasone.

CONCLUSIONS

This study showed that compared with dexamethasone, methylprednisolone could reduce the systemic inflammatory response in severe COVID-19, and its effect was equivalent to that of dexamethasone on other clinical outcomes. It should be noted that the equivalent dose of methylprednisolone used was higher. Based on the evidence of subgroup analyses of RCTs, methylprednisolone, preferably at a moderate dose, has an advantage over dexamethasone in the treatment of patients with severe COVID-19.

Intravenous methylprednisolone pulse therapy and the risk of in-hospital mortality among acute COVID-19 patients: Nationwide clinical cohort study

BACKGROUND

Steroids are widely used to modulate the inflammatory reactions associated with coronavirus disease 2019 (COVID-19); however, the optimal upper limit dose of steroid use for acute COVID-19 care remains unclear and currently available data may suffer from a time-dependent bias of no effectiveness or reversed causation given the desperate situation of treatment during this pandemic. Accordingly, the aim of this study was to elucidate the impact of intravenous pulse therapy with methylprednisolone (500 mg or greater per day) on the risk of in-hospital mortality among patients with COVID-19 by controlling for time-dependent bias.

METHODS

We performed a prospective cohort study with 67,348 hospitalised acute COVID-19 patients at 438 hospitals during 2020-2021 in Japan. The impact of intravenous methylprednisolone pulse therapy on the risk of in-hospital mortality was examined based on hazard ratios (HRs) and 95% confidence intervals (95% CIs), with stratification according to the status of invasive mechanical ventilation (iMV). Time-dependent bias was controlled for in a marginal structural model analysis, with reference to patients without methylprednisolone therapy.

RESULTS

During the study period, 2400 patients died. In-hospital mortality rates of iMV-free patients without or with methylprednisolone pulse therapy were 2.3% and 19.5%, and the corresponding values for iMV-receiving patients were 24.7% and 28.6%, respectively. The marginal structural model analysis showed that intravenous pulse therapy with methylprednisolone was associated with a lower risk of in-hospital mortality among patients receiving-iMV (HR 0.59; 95% CI 0.52-0.68). In contrast, pulse therapy with methylprednisolone increased the risk of in-hospital mortality among iMV-free patients (HR 3.38; 95% CI 3.02-3.79). The benefits of pulse therapy for iMV-receiving patients were greater than in those treated with intermediate/higher doses (40-250 mg intravenously) of methylprednisolone (HR 0.80; 95% CI 0.71-0.89).

CONCLUSION

The results of our study suggest that intravenous methylprednisolone showed dose-response efficiencies, and pulse therapy may benefit critically ill patients with acute COVID-19, such as those requiring iMV.

Are intravenous corticosteroid pulses superior to low dose corticosteroids in patients with severe Covid-19?

Corticosteroids were the first drugs proven to reduce mortality in Covid-19. In June 2020, the RECOVERY group announced the results of their seminal trial showing dexamethasone 6 mg per day was able to reduce 28-day mortality in hospitalized patients with Covid needing supplemental oxygen or mechanical ventilation [1]. Meta-analysis from randomized controlled trials (RCT) in Covid-19 patients confirmed RECOVERY results [2]. In those RCTs, corticosteroid doses were low (dexamethasone 6 mg per day) or intermediate (dexamethasone up to 20mg per day).
