Background Clinicians considered DDS administration to treat SARS-CoV-2 inflammasome. DDS is helpful in the molecular regulation of Nod-like receptor family pyrin domain-containing 3 (NLRP3).Objective To study the targeting of NLRP3 itself or up-/downstream factors of the NLRP3 inflammasome by DDS must be responsible for its observed preventive effects, functioning as a competitor.Methods This is a randomized controlled trial (RCT). We set out to use objective criteria of improvement. We

... the patients with standard Covid-19 acute respiratory distress syndrome (ARDS) treatment with DDS. The RCT results were analyzed.Results ARDS progression was blocked in 17 of 19 total patients at the first period. The 44 subjects were analyzed during the second period. It is significant at the ARDS onset stage. The mortality of ARDS-onset patients was 0% with DDS and 40% without DDS among the total of 65 cases. The t-value of RCT is -1.5, and the p-value is .075475. The result is significant at p < 0.10. ARDS onset with DDS prescribed group survived more 90% than ARDS onset without DDS group. The chi-square is 5.8108. The p-value is .015928. (Significant at p < .05) (RR 0.15, OR 0.09)Conclusion There was a significant difference in DDS treatment results in the ARDS-onset group. We confirmed that DDS clinically treated the onset of ARDS by targeting SARS-CoV-2-activated inflammasomes. Like chemically reacting substances, inflammasome and DDS compete, proving that it is effective in early ARDS.ClinicalTrials.gov Identifier: NCT04918914
