Insights
Hemoperfusion significantly reduced mortality in critical COVID-19 patients by removing pro-inflammatory cytokines. Early intervention with hemoperfusion is recommended for severe cases to improve outcomes.
Area of Science:
- Critical care medicine
- Infectious diseases
- Nephrology
Background:
- COVID-19 can lead to organ failure due to sepsis-like syndromes and cytokine storms.
- Pro-inflammatory cytokine removal is a potential therapeutic strategy for severe COVID-19.
Purpose of the Study:
- To evaluate the efficacy of hemoperfusion in reducing mortality in critically ill COVID-19 patients.
- To assess the impact of hemoperfusion on clinical outcomes in severe COVID-19.
Main Methods:
- A clinical trial involving 68 severe COVID-19 patients (April-June 2020).
- Patients received standard therapy or standard therapy plus 4-hour hemoperfusion for 3 consecutive days.
- Primary outcomes included hospital stay, mechanical ventilation duration, radiologic resolution, and mortality rate.
Main Results:
- Hemoperfusion significantly reduced mortality rates compared to controls (37.1% vs. 63.6%, p=0.02).
- The mortality reduction was more pronounced in patients with a PaO2/FiO2 ratio ≥75.
- No significant differences in demographic or baseline characteristics were observed between groups.
Conclusions:
- Early hemoperfusion can significantly decrease mortality in critically ill COVID-19 patients.
- Hemoperfusion is a promising therapeutic option for managing cytokine storms in severe COVID-19.
Background:
Coronavirus disease-2019 (COVID-19)-related organ failure is partly related to a sepsis-like syndrome and extreme pro-inflammatory cytokine release, named cytokine storm. Therapeutic strategies that prevent the production of or remove the pro-inflammatory cytokines could potentially be an effective therapy in critically afflicted COVID-19 patients.
Methods:
In this clinical trial study, from April until June 2020, 68 COVID-19 patients (35 vs. 33 controls) with severe critical symptoms, and PaO2 /FiO2 (P/F) ratio less than 200 mmHg either received a single standard therapy or a combination of standard treatment for COVID-19 combined with hemoperfusion (hemofilter, HA330 D Javfron) for 4 h, in 3 consecutive days. The length of hospital stay and mechanical ventilation, the resolution of radiologic abnormalities, and the mortality rate were defined as the primary outcomes.
Results:
Demographic characteristics, the acute physiology, and chronic health evaluation score of both groups were similar (p > 0.05). Importantly, we noticed a significant mortality rate reduction in the perfused group compared with controls (37.1% vs. 63.6%, p = 0.02), this positive effect was stronger among those with a P/F ratio higher than 75 (mortality rate of 84.7% for P/F ratio < 75 vs. 15.4% for P/F ratio ≥ 75, p = 0.02).
Conclusions:
The results imply that early start of hemoperfusion could be more effective and significantly reduce the mortality rate among COVID-19 patients with critical diseases.
