Safety and Efficacy of Umbilical Cord Mesenchymal Stem Cell Exosomes in Treating Chronic Cough After COVID-19

Summary

This clinical trial aims to evaluate the safety and effectiveness of umbilical cord mesenchymal stem cell (UCMSC)-derived extracellular vesicle nebulization inhalation therapy for the treatment of chronic cough after COVID-19 infection. The main objective is to assess whether UCMSC-derived exosome nebulization inhalation therapy alleviates chronic cough after COVID-19. Participants will be asked to complete a questionnaire to help researchers evaluate their cough severity and to record their scores before nebulization inhalation of UCMSC-derived exosomes. Participants will receive either continuous nebulized inhalation of UCMSC-derived exosomes for 5 days, twice daily, or no treatment. Researchers will compare the experimental and control groups to evaluate the safety and efficacy of UCMSC-derived exosomes for the treatment of chronic cough after COVID-19 infection.
