ABSTRACT

OBJECTIVE: Post-acute sequelae of SARS-CoV2 infection (PASC) are a novel terminology used to describe post-COVID persistent symptoms, mimicking somehow the previously described chronic fatigue syndrome (CFS). In this manuscript, we evaluated a therapeutical approach to address PASC-derived fatigue in a cohort of past-COVID-19 positive patients. PATIENTS AND METHODS: A number of 100 patients, previously diagnosed as COVID-19 positive subjects and meeting our eligibility criteria, was diagnosed having PASC-related fatigue. They were recruited in the study and treated with oxygen-ozone autohemotherapy (O2-O3-AHT), according to the SIOOT protocol. Patients' response to O2-O3-AHT and changes in fatigue were measured with the 7-scoring Fatigue Severity Scale (FSS), according to previously published protocols. RESULTS: Statistics assessed that the effects of O2-O3-AHT on fatigue reduced PASC symptoms by 67%, as a mean, in all the investigated cohort of patients (H = 148.4786 p < 0.0001) (Figure 1). Patients following O2-O3-AHT therapy, quite completely recovered for PASC-associated fatigue, a quote amounting to about two fifths (around 40%) of the whole cohort undergoing ozone treatment and despite most of patients were female subjects, the effect was not influenced by sex distribution (H = 0.7353, p = 0.39117). CONCLUSIONS: Ozone therapy is able to recover normal functionality and to relief pain and discomfort in the form of PASC-associated fatigue in at least 67% of patients suffering from post-COVID sequelae, aside from sex and age distribution.

ABSTRACT

Influenza and RSV are human viruses responsible for outbreaks in hospitals, long-term care facilities and nursing homes. The present study assessed an air treatment using ozone at two relative humidity conditions (RHs) in order to reduce the infectivity of airborne influenza. Bovine pulmonary surfactant (BPS) and synthetic tracheal mucus (STM) were used as aerosols protectants to better reflect the human aerosol composition. Residual ozone concentration inside the aerosol chamber was also measured. RSV's sensitivity resulted in testing its resistance to aerosolization and sampling processes instead of ozone exposure. The results showed that without supplement and with STM, a reduction in influenza A infectivity of four orders of magnitude was obtained with an exposure to 1.70 ± 0.19 ppm of ozone at 76% RH for 80 min. Consequently, ozone could be considered as a virucidal disinfectant for airborne influenza A. RSV did not withstand the aerosolization and sampling processes required for the use of the experimental setup. Therefore, ozone exposure could not be performed for this virus. Nonetheless, this study provides great insight for the efficacy of ozone as an air treatment for the control of nosocomial influenza A outbreaks.

ABSTRACT

BACKGROUND: Following positive experience on the use of blood ozonation in SARS-CoV-2, the CORMOR randomized trial was designed to evaluate the adjuvant role of oxygen/ozone therapy in mild to moderate SARS-CoV-2 pneumonia. METHODS: The trial (ClinicalTrial.gov NCT04388514) was conducted in four different Italian centers (April-October 2020). Patients were treated according to best available standard of care (SoC) therapy, with or without O3-autohemotherapy (O3-AHT). RESULTS: A total of 92 patients were enrolled: SoC + O3-AHT (48 patients) were compared to the SoC treatment (44 patients). The two groups differed in steroids therapy administration (72.7% in SoC arm vs. 50.0% in O3-AHT arm; p = 0.044). Steroid therapy was routinely started when it was subsequently deemed as effective for the treatment of COVID-19 disease. No significant differences in mortality rates, length of hospital stay, mechanical ventilation requirement and ICU admission were observed. Clinical improvement in patients with pneumonia was assessed according to a specifically designed score (decrease in SIMEU class, improvement in radiology imaging, improvement in PaO2/FiO2, reduction in LDH and requirement of oxygen therapy ≤ 5 days). Score assessment was performed on day-3 (T3) and day-7 (TEnd) of O3-AHT treatment. A significant increase in the score was reported at TEnd, in the O3-AHT treatment arm (0 [0-1] in the SoC arm vs. 2 [1-3] the O3-AHT arm; p = 0.018). No adverse events related O3-AHT treatment was observed. CONCLUSION: In mild-to-moderate pneumonia due to SARS-CoV-2, adjuvant oxygen/ozone therapy did not show any effect on mortality, or mechanical intubation but show a clinical improvement a day 7 from randomization in a composite clinical endpoint. Larger Randomized prospective studies alone or in combination with steroids are needed to confirm our results.

ABSTRACT

OBJECTIVE: In the current pandemic, Health Care Workers (HCWs) are at a high risk of developing COVID-19. Preventive methods like the use of personal protective equipment, isolation, social distancing, and chemoprophylaxis show limited benefit. Despite standard prophylaxis, many of the HCWs develop COVID-19. Medical ozone therapy has immunomodulatory, antioxidant and antiviral effect, and, therefore, it can be explored as prophylaxis for COVID-19. PATIENTS AND METHODS: We conducted a retrospective controlled cohort study. IV ozonized saline was administered once a day for a total of 4 days in one month in addition to standard prophylaxis for COVID-19 to HCWs in a dedicated COVID hospital. Fresh ozonized saline was prepared for every administration and was given over 1 hour. RESULTS: There were 235 HCWs, 64 received the ozone prophylaxis and 171 did not. The incidence of COVID-19 was significantly (p=0.04) lesser in HCWs that received ozone prophylaxis (4.6%) as compared to those who did not (14.03%). The benefit was seen irrespective of the risk of exposure. In the red zone, 8.69% of the HCWs who received ozone prophylaxis tested positive as opposed to 15.3% of those who did not. In the orange zone, 4.34% of the HCWs who received ozone prophylaxis tested positive, remarkably lesser than those who did not (20%). In the green zone, none of the HCWs who received ozone prophylaxis tested positive; however, 3.4% of the HCWs who did not receive ozone prophylaxis tested positive. No major adverse events were noted. CONCLUSIONS: IV ozonized saline can be used in addition to the standard prophylactic regimen for the prevention of COVID-19 in HCWs. Prospective larger studies are required to establish the potency of IV ozonized saline as prophylaxis.

ABSTRACT

OBJECTIVE: This study evaluated the potential efficacy of a novel approach to treat COVID-19 patients, using an oxygen-ozone (O2-O3) mixture, via a process called Oxygen-Ozone- Immunoceutical Therapy. The methodology met the criteria of a novel, promising approach to treat successfully elderly COVID-19 patients, particularly when hospitalized in intensive care units (ICUs) Experimental design: We investigated the therapeutic effect of 4 cycles of O2-O3 in 50 hospitalized COVID-19 subjects suffering from acute respiratory disease syndrome (ARDS), aged more than 60 years, all males and undergoing non invasive mechanical ventilation in ICUs. RESULTS: Following O2-O3 treatment a significant improvement in inflammation and oxygenation indexes occurred rapidly and within the first 9 days after the treatment, despite the expected 14-20 days. A significant reduction of inflammatory and thromboembolic markers (CRP, IL-6, D-dimer) was observed. Furthermore, amelioration in the major respiratory indexes, such as respiratory and gas exchange markers (SatO2%, PaO2/FiO2 ratio), was reported. CONCLUSION: Our results show that O2-O3 treatment would be a promising therapy for COVID-19 patients. It leads patients to a fast recovery from ARDS via the improvement of major respiratory indexes and blood gas parameters, following a relatively short time of dispensed forced ventilation (about one to two weeks). This study may encourage the scientific community to further investigate and evaluate the proposed method for the treatment of COVID-19 patients.

ABSTRACT

The evaluation of new therapeutic resources against coronavirus disease 2019 (COVID-19) represents a priority in clinical research considering the minimal options currently available. To evaluate the adjuvant use of systemic oxygen-ozone administration in the early control of disease progression in patients with COVID-19 pneumonia. PROBIOZOVID is an ongoing, interventional, randomized, prospective, and double-arm trial enrolling patient with COVID-19 pneumonia. From a total of 85 patients screened, 28 were recruited. Patients were randomly divided into ozone-autohemotherapy group (14) and control group (14). The procedure consisted in a daily double-treatment with systemic Oxygen-ozone administration for 7 days. All patients were treated with ad interim best available therapy. The primary outcome was delta in the number of patients requiring orotracheal-intubation despite treatment. Secondary outcome was the difference of mortality between the two groups. Moreover, hematological parameters were compared before and after treatment. No differences in the characteristics between groups were observed at baseline. As a preliminary report we have observed that one patient for each group needed intubation and was transferred to ITU. No deaths were observed at 7-14 days of follow up. Thirty-day mortality was 8.3% for ozone group and 10% for controls. Ozone therapy did not significantly influence inflammation markers, hematology profile, and lymphocyte subpopulations of patients treated. Ozone therapy had an impact on the need for the ventilatory support, although did not reach statistical significance. Finally, no adverse events related to the use of ozone-autohemotherapy were reported. Preliminary results, although not showing statistically significant benefits of ozone on COVID-19, did not report any toxicity.
