Probable positive effects of the photobiomodulation as an adjunctive treatment in COVID-19: A systematic review


Background: COVID-19, as a newly-emerged viral infection has now spread all over the world after originating in Wuhan, China. Pneumonia is the hallmark of the disease, with dyspnea in half of the patients and acute respiratory distress syndrome (ARDS) in up to one -third of the cases. Pulmonary edema, neutrophilic infiltration, and inflammatory cytokine release are the pathologic signs of this disease. The anti-inflammatory effect of the photobiomodulation (PBM) has been confirmed in many previous studies. Therefore, this review study was conducted to evaluate the direct effect of PBM on the acute lung inflammation or ARDS and also accelerating the regeneration of the damaged tissues. The indirect effects of PBM on modulation of the immune system, increasing the blood flow and oxygenation in other tissues were also considered.

Methodology: The databases of PubMed, Cochrane library, and Google Scholar were searched to find the relevant studies. Keywords included the PBM and related terms, lung inflammation, and COVID-19 -related signs. Studies were categorized with respect to the target tissue, laser parameters, and their results.

Results: Seventeen related papers were included in this review. All of them were in animal models. They showed that the PBM could significantly decrease the pulmonary edema, neutrophil influx, and generation of pro-inflammatory cytokines (tumor necrosis factor-α (TNF-α), interleukin 1 beta (IL-1β), interleukin 6 (IL-6), intracellular adhesion molecule (ICAM), reactive oxygen species (ROS), isoform of nitric oxide synthase (iNOS), and macrophage inflammatory protein 2 (MIP-2)).

Conclusion: Our findings revealed that the PBM could be helpful in reducing the lung inflammation and promoting the regeneration of the damaged tissue. PBM can increase the oxygenation indirectly in order to rehabilitate the affected organs. Thus, the infra-red lasers or light-emitting diodes (LEDs) are recommended in this regard.

Photobiomodulation Therapy Combined With Static Magnetic Field in Patients With COVID-19

Coronavirus disease 2019 (COVID-19) is a disease caused by a novel coronavirus called SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2). The most characteristic symptom of patients with COVID-19 is respiratory distress, leading to inability to sustain spontaneous breathing. In addition, patients with COVID-19 have dyspnea and respiratory muscle fatigue. Therefore, it is necessary to use strategies that minimize the impact of COVID-19 on the respiratory muscles, accelerating the ventilatory weaning process and optimizing the functional capacity of the involved muscles.

Low level laser therapy as a modality to attenuate cytokine storm at multiple levels, enhance recovery, and reduce the use of ventilators in COVID-19

The global pandemic COVID-19 is a contagious disease and its mortality rates ranging from 1% to 5% are likely due to acute respiratory distress syndrome (ARDS), and cytokine storm. A significant proportion of patients who require intubation succumb to the disease, despite the availability of ventilators and the best treatment practices. Researchers worldwide are in search of anti-inflammatory medicines in the hope of finding a cure for COVID-19. Low-level laser therapy (LLLT) has strong, anti-inflammatory effects confirmed by meta-analyses, and it may be therapeutic to ARDS.

Photodynamic Therapy for the Treatment of COVID-19

Until now there is no vaccine or reliable treatment for the COVID-19 pandemic. The fundamental mechanisms of non-invasive low-level laser in photobiomodulation (PBM) and photodynamic therapy is to stimulate the mitochondrial respiratory chain where a transient release of non-cytotoxic levels of reactive oxygen species (ROS) will lead to positive modulation of the immune response. As previous studies mentioned that the most important strategy for COVID-19 management is oxygenation and faster rehabilitation of the damaged tissue, antiviral effects, and, finally, reduction or controlling the cytokine storm by reducing inflammatory agents. PBM may be used as adjuvant therapy or even an alternative therapy in all these mechanisms without side effects and drug interactions.

Light as a potential treatment for pandemic coronavirus infections

The recent outbreak of COVID-19, which continues to ravage communities with high death tolls and untold psychosocial and catastrophic economic consequences, is a vivid reminder of nature’s capacity to defy contemporary healthcare. The pandemic calls for rapid mobilization of every potential clinical tool, including phototherapy-one of the most effective treatments used to reduce the impact of the 1918 “Spanish influenza” pandemic.
