Oxygen-Ozone as Adjuvant Treatment in Early Control of COVID-19 Progression and Modulation of the Gut Microbial Flora (PROBIOZOVID)

Oxygen-Ozone as Adjuvant Treatment in Early Control of Disease Progression in Patients With COVID-19 Associated With Modulation of the Gut Microbial Flora

Italy was the first European country affected by a severe outbreak of the Severe Acute Respiratory Syndrome - CoronaVirus-2 (SARS-CoV-2) epidemic emerged from Wuhan region (China), with a high morbidity and mortality associated with the disease.

In light of its pandemic spread and the very limited therapeutic options, COronaVIrus Disease 19 (COVID-19) is considered an unprecedented global health challenge. Therefore, the evaluation of new resources, designed in the first instance for other pathologies but potentially active against COVID-19, represents a priority in clinical research.

This is an interventional, non-pharmacological, open, randomized, prospective, non-profit study on the adjuvant use of oxygen ozone therapy plus probiotic supplementation in the early control of disease progression in patients with COVID-19.

Contextually, all patients are treated with the current standard of care on the basis of the interim guidelines of the Italian Society of Infectious and Tropical Diseases.

The main purpose of the study is to evaluate the effectiveness of an ozone therapy-based intervention (accompanied by supplementation with probiotics) in containing the progression of COVID-19 and in preventing the need for hospitalization in intensive care units.

Study Overview

• Status: Unknown
• Conditions: Coronavirus Infection; Pneumonia, Viral; SARS-CoV 2; COVID
• Intervention / Treatment: Drug: Azithromycin; Drug: hydroxychloroquine; Other: Oxygen-ozone therapy, probiotic supplementation and Standard of care; Dietary supplement: SivoMixx (200 billion)

Detailed Description

Several studies analyzed the mechanisms by which ozone therapy could combat viral infections. In particular, 1) the improvement of the release of oxygen in the peripheral tissues, 2) the anti-inflammatory action 3) a virucidal activity have been described.

In view of these properties, a number of international clinical trials on the topic are currently ongoing.

Hospitalization, dietary changes, use of antibiotics and systemic inflammation related to COVID-19 are all variables that contribute to changes in the intestinal and lung microbiota with significant repercussions on the outcomes of the disease. Furthermore, the use of ozone therapy could also lead to a modification of the microbial flora. Probiotic supplementation can help to correct these issues.
