The Effectiveness of Photobiomudulation therapy (PBMT) in COVID-19 Infection

Introduction: Currently, the COVID-19 pandemic is an important health challenge worldwide Due to the cytokine storm, the mortality rate in acute respiratory distress syndrome (ARDS) is high, but until now no therapy for these patients was approved The aim of this review was to discuss the possible anti-inflammatory effect of photobiomodulation therapy (PBMT) on ARSD patients and present the potential role of low-level laser therapy (LLLT) in the improvement of respiratory symptoms associated with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Methods: Studies about PBMT in inflammation and ARSD patients were examined A primary search with reviewing English-language citations between 2005 and 2020 using the keywords COVID-19, ADRS, cytokine storm, low-level laser therapy, anti-inflammatory, and photobiomodulation was performed The initial search yielded 818 articles;however, 60 articles were selected and discussed in the present study Results: The results of the selected studies showed the usefulness of PBMT in the treatment of inflammation and ARSD in patients with COVID-19 infection This therapy is non-invasive and safe to modulate the immune responses in ARSD patients Conclusion: PBMT can potentially reduce the viral load and bacterial super-infections in patients with COVID-19 infection and control the inflammatory response Therefore, the use of PBMT could be an efficient strategy for preventing severe and critical illness in SARS-COV2 infection © 2020 All rights reserved
