ABSTRACT

BACKGROUND: Cardiovascular involvement in SARS-CoV-2 infection has emerged as one of viral major clinical features during actual pandemic; limb arterial ischemic events, venous thrombosis, acute myocardial infection and stroke have occurred in patients. Acute aortic conditions have also been described, followed by interesting observations on cases, hypothesis, raised since the emergence of the pandemics. METHODS: a review of cases in literature of aortic pathology in patients with clinically suspected/microbiologically confirmed COVID-19 infection has been carried out to analyze anagraphic data, clinical presentation, treatment options and outcome. RESULTS: Seventeen cases have been included. Mean age of patients was 58.6 ± 15.2 years, with a male to female ratio of 12:15 (70.5% vs. 29.5%). Comorbidities were reported in 11 cases (64.7%), but in 5 cases (29.4%) no previous pathology was signaled in history. Hypertension was the most frequently reported comorbidity, in 8 cases, (47%), followed by renal pathology (17.6%), coronary artery disease (17.6%), previous aortic surgery (11.7%) and arrhythmia (11.7%); but also cerebrovascular disease, diabetes, autoimmune conditions, previous neoplasia and arrhythmia were reported once each. Fever and thoracic pain were the most frequently reported findings at presentation (8 cases, 47% each), followed by respiratory symptoms (6, 35.2%), low lymphocyte count (17.6%), features related to aneurysm rupture, ischemic stroke, abdominal pain and acute renal insufficiency. Reported aortic pathology included: type A aortic dissection (11 cases; 64.7%); new pathology of previous aortic graft (2 cases, 11.7%); 2 aortitis, 1 associated with type A aortic dissection; 1 thoraco-abdominal aortic aneurysm, 1 ruptured aortic aneurysm and 1 aortic embolizing thrombosis. Open surgery was carried out in 10 cases (58.8%), endovascular treatment in 3 (17.6%). Three patients (17.6%) died before surgery. Exitus was reported in 4 cases, with a total mortality of 23.5%. CONCLUSIONS: Acute aortic events have occurred during pandemic in patients with clinically suspected/microbiologically confirmed COVID-19 infection. Confounding clinical features at presentation, the importance of anamnestic details (as previous vascular graft implant), the observed surgical and postoperatory challenges may suggest the need to consider the implications of the possible link between acute aortic events and SARS-CoV-2 infection, in order to promptly correctly diagnose the patient and respond to specific needs.

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.

ABSTRACT

Background: Gastrointestinal disorders are frequent in COVID-19 and SARS-CoV-2 has been hypothesized to impact on host microbial flora and gut inflammation, infecting intestinal epithelial cells. Since there are currently no coded therapies or guidelines for treatment of COVID-19, this study aimed to evaluate the possible role of a specific oral bacteriotherapy as complementary therapeutic strategy to avoid the progression of COVID-19. Methods: We provide a report of 70 patients positive for COVID-19, hospitalized between March 9th and April 4th, 2020. All the patients had fever, required non-invasive oxygen therapy and presented a CT lung involvement on imaging more than 50%. Forty-two patients received hydroxychloroquine, antibiotics, and tocilizumab, alone or in combination. A second group of 28 subjects received the same therapy added with oral bacteriotherapy, using a multistrain formulation. Results: The two cohorts of patients were comparable for age, sex, laboratory values, concomitant pathologies, and the modality of oxygen support. Within 72 h, nearly all patients treated with bacteriotherapy showed remission of diarrhea and other symptoms as compared to less than half of the not supplemented group. The estimated risk of developing respiratory failure was eight-fold lower in patients receiving oral bacteriotherapy. Both the prevalence of patients transferred to ICU and mortality were higher among the patients not treated with oral bacteriotherapy. Conclusions: A specific bacterial formulation showed a significant ameliorating impact on the clinical conditions of patients positive for SARS-CoV-2 infection. These results also stress the importance of the gut-lung axis in controlling the COVID-19 disease.
