Abstract
Background: Photobiomodulation therapy (PBMT) using devices to deliver red and/or near-infrared light to tissues has shown promising effects in clinical settings for respiratory diseases, including potential benefits in managing symptoms associated with COVID-19. Objective: To determine if at-home self-administered PBMT for patients with COVID-19 is safe and effective. Methods: This was a randomized controlled trial (RCT) carried out at home during the COVID-19 pandemic (September 2020 to August 2021). The treatment group self-administered the Vielight RX Plus PBMT device (635 nm intranasal and 810 nm chest LEDs) and were monitored remotely. Eligible patients scored 4-7 (out of 7) for severity on the Wisconsin Upper Respiratory Symptom Survey (WURSS-44). Patients were randomized equally to Control group receiving standard-of-care (SOC) only or Treatment group receiving SOC plus PBMT. The device was used for 20 min 2X/day for 5 days and, subsequently, once daily for 30 days. The primary end-point was time-to-recovery (days) based on WURSS-44 question 1, "How sick do you feel today?". Subgroup analysis was performed, and Kaplan-Meier and Cox Proportional Hazards analysis were employed. Results: One hundred and ninety-nine eligible patients (18-65 years old) were divided into two subgroups as follows: 136 patients with 0-7 days of symptoms at baseline and 63 patients with 8-12 days of symptoms. Those with 0-7 days of symptoms at baseline recovered significantly faster with PBMT. The median for Treatment group was 18 days [95% confidence interval (CI), 13-20] versus the Control group 21 days (95% CI, 15-28), p = 0.050. The treatment:control hazard ratio was 1.495 (95% CI, 0.996-2.243), p = 0.054. Patients with symptom duration ≥7 days did not show any significant improvement. No deaths or severe adverse events (SAEs) occurred in the Treatment group, whereas there was 1 death and 3 SAEs requiring hospitalization in the Control group. Conclusions: Patients with ≤7 days of COVID-19 symptoms recovered significantly faster with PBMT compared to SOC. Beyond 7 days, PBMT showed no superiority over SOC. Trial Registration: ClinicalTrials.gov NCT04418505.

Abstract
Background: Sepsis-induced acute lung injury (ALI) is a clinical syndrome characterized by excessive uncontrolled inflammation. Photobiomodulation such as light-emitting diode (LED) irradiation has been used to attenuate inflammatory disease. Objective: The protective effect of 630 nm LED irradiation on sepsis-induced ALI remains unknown. The purpose of this study was to investigate the role of 630 nm LED irradiation in sepsis-induced ALI and its underlying mechanism. Methods and results: C57BL/6 mice were performed cecal ligation and puncture (CLP) for 12 h to generate experimental sepsis models. Histopathology analysis showed that alveolar injury, inflammatory cells infiltration, and hemorrhage were suppressed in CLP mice after 630 nm LED irradiation. The ratio of wet/dry weigh of lung tissue was significantly inhibited by irradiation. The number of leukocytes was reduced in bronchoalveolar lavage fluid. Reverse transcription-quantitative polymerase chain reaction (RT-qPCR) results and enzyme-linked immunosorbent assay showed that 630 nm LED irradiation significantly inhibited the mRNA and protein levels of M1 macrophage-related genes in the lung of CLP-induced septic mice. Meanwhile, LED irradiation significantly inhibited signal transducer and activator of transcription 1 (STAT1) phosphorylation in the lung of septic mice. In vitro experiments showed that 630 nm LED irradiation significantly inhibited M1 genes mRNA and protein expression in THP-1-derived M1 macrophages without affecting the cell viability. LED irradiation also significantly inhibited the level of STAT1 phosphorylation in THP-1-derived M1 macrophages. Conclusions: We concluded that 630 nm LED is promising as a treatment against ALI through inhibiting M1 macrophage polarization, which is associated with the downregulation of STAT1 phosphorylation.

Abstract
With the global epidemic and prevention of the COVID-19, long COVID-19 sequelae and its comprehensive prevention have attracted widespread attention. Long COVID-19 sequelae refer to that three months after acute COVID-19, the test of SARS-CoV-2 is negative, but some symptoms still exist, such as cough, prolonged dyspnea and fatigue, shortness of breath, palpitations and insomnia. Its pathological mechanism is related to direct viral damage, immunopathological response, endocrine and metabolism disorders. Although there are more effective methods for treating COVID-19, the treatment options available for patients with long COVID-19 remain quite limited. Psychophysical therapies, such as exercise, oxygen therapy, photobiomodulation, and meditation, have been attempted as treatment modalities for long COVID-19, which have the potential to promote recovery through immune regulation, antioxidant effects, and neuroendocrine regulation. Neuroendocrine regulation plays a significant role in repairing damage after viral infection, regulating immune homeostasis, and improving metabolic activity in patients with long COVID-19. This review uses oxytocin as an example to examine the neuroendocrine mechanisms involved in the psychophysical therapies of long COVID-19 syndrome and proposes a psychophysical strategy for the treatment of long COVID-19.

Abstract
There is increasing recognition of post-COVID-19 sequelae involving chronic fatigue and brain fog, for which photobiomodulation (PBM) therapy has been utilized. This open-label, pilot, human clinical study examined the efficacy of two PBM devices, for example, a helmet (1070 nm) for transcranial (tPBM) and a light bed (660 and 850 nm) for whole body (wbPBM), over a 4-week period, with 12 treatments for two separate groups (n = 7 per group). Subjects were evaluated with a neuropsychological test battery, including the Montreal Cognitive Assessment (MoCA), the digit symbol substitution test (DSST), the trail-making tests A and B, the physical reaction time (PRT), and a quantitative electroencephalography system (WAVi), both pre- and post- the treatment series. Each device for PBM delivery was associated with significant improvements in cognitive tests (p < 0.05 and beyond). Changes in WAVi supported the findings. This study outlines the benefits of utilizing PBM therapy (transcranial or whole-body) to help treat long-COVID brain fog.

Abstract
Photobiomodulation therapy (PBMT) employing laser light has been emerging as a safe strategy to challenge viruses. In this study the effect of blue and near-infrared (NIR) laser light was assessed in an in vitro model of SARS-CoV-2 infection. PBMT at blue wavelength inhibited viral amplification when the virus was directly irradiated and then transferred to cell culture and when cells already infected were treated. The NIR wavelength resulted less efficacious showing a minor effect on the reduction of the viral load. The cells receiving the irradiated virus or directly irradiated rescued their viability to level comparable to not treated cells. Virion integrity and antigenicity were preserved after blue and NIR irradiation, suggesting that the PBMT antiviral effect was not correlated to viral lipidic envelope disruption. Our results suggested that PBMT can be considered a valid strategy to counteract SARS-CoV-2 infection, at least in vitro.

Abstract
Licht, Laser und Akupunktur haben auch in der aktuellen Pandemie wichtige Beiträge zur Medizin geleistet. Hauptziel einer vor kurzem veröffentlichten Übersichtsarbeit war es zu untersuchen, wie Licht als therapeutische Methode während der durch COVID-19 ausgelösten Krise bislang eingesetzt wurde. Ein weiteres Ziel ist es, Wissenschaftlerinnen und Wissenschaftler sowie die Industrie zu ermutigen, schnell neue einfache Verfahren der Photobiomodulationstherapie (PBMT) und/oder photodynamischen Therapie (PDT) für zu Hause zu entwickeln. Die bisherigen Ergebnisse zeigten, dass PBMT teilweise erfolgreich bei SARSCoV-2-Infektionen angewendet werden kann und signifikante Verbesserungen bei Atemwegsentzündungen und dem allgemeinen klinischen Zustand der Patientinnen und Patienten ermöglichte. Die Anwendung nur in einer begrenzten Anzahl von Fällen impliziert die Notwendigkeit zukünftiger randomisierter, placebokontrollierter klinischer Studien, um die Wirkung von PBMT und PDT bei COVID-19 tatsächlich zu objektivieren. Bei dieser anhaltenden und herausfordernden Suche nach dem scheinbar nicht greifbaren Ende dieser Pandemie scheinen die PBMT und PDT nicht-invasive, leicht zugängliche, sichere und nebenwirkungsfreie Methoden zu sein.

A Novel Approach of Combining Methylene Blue Photodynamic Inactivation, Photobiomodulation and Oral Ingested Methylene Blue in COVID-19 Management: A Pilot Clinical Study with 12-Month Follow-Up. Antioxidants (Basel) 2022; 11:2211. [PMID: 36358582 PMCID: PMC9686966 DOI: 10.3390/antiox11112211] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2022] [Revised: 11/02/2022] [Accepted: 11/04/2022] [Indexed: 08/26/2023] Open
Abstract
Coronavirus disease 2019 (COVID-19) caused by SARS-CoV-2 virus was first recognized in late 2019 and remains a significant threat. We therefore assessed the use of local methylene blue photodynamic viral inactivation (MB-PDI) in the oral and nasal cavities, in combination with the systemic anti-viral, anti-inflammatory and antioxidant actions of orally ingested methylene blue (MB) and photobiomodulation (PBM) for COVID-19 disease. The proposed protocol leverages the separate and combined effects of MB and 660nm red light emitted diode (LED) to comprehensively address the pathophysiological sequelae of COVID-19. A total of eight pilot subjects with COVID-19 disease were treated in the Bahamas over the period June 2021-August 2021, using a remote care program that was developed for this purpose. Although not a pre-requisite for inclusion, none of the subjects had received any COVID-19 vaccination prior to commencing the study. Clinical outcome assessment tools included serial cycle threshold measurements as a surrogate estimate of viral load; serial online questionnaires to document symptom response and adverse effects; and a one-year follow-up survey to assess long-term outcomes. All subjects received MB-PDI to target the main sites of viral entry in the nose and mouth. This was the central component of the treatment protocol with the addition of orally ingested MB and/or PBM based on clinical requirements. The mucosal surfaces were irradiated with 660 nm LED in a continuous emission mode at energy density of 49 J/cm2 for PDI and 4.9 J/cm2 for PBM. Although our pilot subjects had significant co-morbidities, extremely high viral loads and moderately severe symptoms during the Delta phase of the pandemic, the response to treatment was highly encouraging. Rapid reductions in viral loads were observed and negative PCR tests were documented within a median of 4 days. These laboratory findings occurred in parallel with significant clinical improvement, mostly within 12-24 h of commencing the treatment protocol. There were no significant adverse effects and none of the subjects who completed the protocol required in-patient hospitalization. The outcomes were similarly encouraging at one-year follow-up with virtual absence of "long COVID" symptoms or of COVID-19 re-infection. Our results indicate that the protocols may be a safe and promising approach to challenging COVID-19 disease. Moreover, due its broad spectrum of activity, this approach has the potential to address the prevailing and future COVID-19 variants and other infections transmitted via the upper respiratory tract. Extensive studies with a large cohort are warranted to validate our results.
