Several patients with hypoxaemic SARS-CoV2 pneumonia were able to benefit from hyperbaric oxygen treatment (HBOT) in China. In a clinical case published in the Chinese journal of hyperbaric medicine, treatment with repeated HBO sessions prevented admission to intensive care unit with mechanical ventilation in a patient aged 69 who presented with signs of respiratory decompensation. HBOT is the most powerful oxygenation modality in the body today. HBOT can dramatically increase the amount of dissolved oxygen in the blood. HBOT not only promotes blood transport but also its tissue delivery. Furthermore, HBOT has specific immunomodulatory properties, both humoral and cellular, making it possible, for example, to reduce the intensity of the inflammatory response and to stimulate antioxidant defenses by repeating sessions. A virucidal capacity of HBOT might also be involved. HBOT is generally regarded as safe with very few adverse events. Following this feedback, it is proposed in the context of crisis management related to SARS-CoV2 to assess the value of HBO treatment of patients with CoV2 pneumonia. Indeed, it seems essential to propose therapeutic strategies to limit the risk of respiratory decompensation requiring admission to intensive care unit for patients with SARS-CoV2 pneumonia.
Why is the research needed? The pandemic known as COVID-19 is now spreading across the world with currently (April 10, 2020) more than 1 115 530 active cases and 96 791 deaths. In most affected countries the current goal is to 'flatten the curve' of the epidemic since there is no health care system that is able to treat an extremely high volume of patients all at once. There is a need for immediately applicable treatments for the patients at highest risk, which gains time until targeted therapies become available. A key feature in the pathomechanism of the disease is that the virus elicits an immunological over-reaction in the human body termed 'cytokine storm'. In susceptible patients this hyper-inflammation itself is a significant burden and may even inhibit the body to generate antibodies against the virus in adequate quantities. Therefore, identifying the subset of patients with excess cytokine response and supplementing them with convalescent plasma from recovered donors may be a life-saving treatment option. What is our study about? In light of recent promising data on plasma therapy in the treatment of COVID-19 and other viral epidemics, there is a need for better understanding the cytokine response to the virus in order to better characterize the target population for convalescent plasma therapy. Our hypothesis is that convalescent plasma transfusion from healthy donors who recovered from SARS CoV-2 is able to reduce the cytokine storm in addition to replenish the patient's own antibodies in the acutely infected phase of the disease. A plasmapheresis donation of 400ml will be performed in subjects who recovered from COVID-19 and who are otherwise eligible for plasma donation. The sample will be tested for anti-SARS CoV-2 neutralizing antibody titers and those that reach the level of 1:320 will be processed for transfusion at the Hungarian National Transfusion Service. Recipients will be COVID-19 patients requiring hospitalization regardless of the severity of the disease or other co-morbidities. A blood-type matched transfusion of 200 ml convalescent plasma will be infused in a single sitting through an iv. infusion of 4 hours. Recipients will be followed up at days 1, 3,7,12, 17, 28 for clinical symptoms, antibody levels and cytokine response.
Retrospective study from November 2019 -Febrauary 2020 on severe respiratory illness to access the presence or absence of COVID-19 in patients samples by real-time PcR
The overall objective of this project is to develop an emergent treatment protocol using adoptive T-cell therapy for the treatment of severe COVID-19. The central hypothesis is that SARS-CoV-2 specific T cells from convalescent donors who have recovered from COVID-19 can be manufactured expeditiously for the treatment of severe SARS-CoV-2 infections.
This is a Phase II pilot exploratory study designed to investigate if prophylactic treatment with short term steroids administered to high risk Covid-19 patient might prevent cytokine storm and progression to respiratory failure. High risk is defined based on serologic markers of inflammation that include abnormalities of Interleukin 6 (IL-6), Ferritin , D-dimer, Lactate Dehydrogenase (LDH), as well as lymphopenia and impaired O2 saturation prior to or on the 7th day of first symptom of Covid-19.
Electrocardiographic (ECG) evaluation of patients with severe acute respiratory syndrome coronavirus 2 (SARS-Cov-2) infection. The present study involves three different phases of evaluation of the ECG traces of hospitalized patients with SARS-CoV-2 infection. - Phase 1: it is proposed to collect and retrospectively analyze the ECGs of hospitalized patients with severe SARS-CoV-2 infection which led to invasive ventilation or patient death as a consequence and, if available, also possible troponin dosage; - Phase 2: aims to collect and analyze the ECGs of consecutive hospitalized patients with SARS-CoV-2 infection and evaluate their relationship with the course of the disease, cardiac involvement and prognosis; - Phase 3: it is proposed to repeat ECG and to carry out echocardiogram to patients with SARS-CoV-2 infection after 3 months from hospital discharge by simultaneously performing, if deemed clinically indicated, also cardiac magnetic resonance. In this phase, any evolutions of ECG alterations of the acute phase will be described and the relationship with cardiac involvement will be assessed.
The goal of this clinical trial is to investigate the therapeutic efficacy of rapidly correcting vitamin D deficiency in adults with the use of 25-hydroxyvitamin D3 [25(OH)D3] for reducing the risk of acquiring the SARS-CoV-2 (COVID-19) viral infection and mitigating morbidity and mortality associated with this infection. This evidence-based hypothesis is related to several observations. Macrophages, activated T and B lymphocytes have a vitamin D receptor and 1,25-dihydroxyvitamin D3 induces defensin protein synthesis, influences immunoglobulin production and modulates T-cell cytokine production and functions. 1,25-dihydroxyvitamin D3 also reduces the angiotensin-converting enzyme 2 (ACE2) that is believed to serve as the binding site and gateway for COVID-19 to become infectious. This is a multicenter randomized3 doubleblinded placebo-controlled study aimed at determining the benefits of 25(OH)D3 treatment for the prevention of COVID-19 infection and improving clinical outcomes in infected patients. The investigators plan to recruit 1500 subjects in 3 study groups that include hospital health providers, patients with a positive test for COVID-19 and their relatives with a negative test. Eligible subjects in each study group with a documented serum level of 25(OH)D < 20 ng/mL will be randomized. Recruited subjects will be given 25 mcg of 25(OH)D3 daily or an identically appearing placebo at the time of randomization for two months. Three hospitals will participate and the sample size is foreseen to be equally distributed between the three. Since the clinical trial is designed as minimal risk a formal committee for data monitoring is not foreseen. However, potential toxicity will be monitored every 4 weeks with a serum calcium, albumin and creatinine by the PI and the study coordinators. If the corrected serum calcium increases above 10.6 mg/dl and a repeat confirms that the calcium is above 10.6 mg/dL the subject will be dropped from the study and referred to his or her PCP. Early signs and symptoms of vitamin D toxicity associated with hypercalcemia are increased thirst, increase in frequency of urination, especially at night. The subjects will be followed up weekly by phone to ask about their sign and symptoms.
Creation of an Institutional Registry system for patients with confirmed COVID-19 infection with the collection of epidemiological data, risk factors, diagnosis, prognoses, treatment, follow-up and survival.
This case series trial aims to evaluate the effect of a modified pedicle subepithelial connective tissue graft in creating anatomical papilla around one-stage delayed implant in the esthetic zone to establish better esthetics.
The Swiss-Ped-IBrainD is a national patient registry that collects information on diagnosis, symptoms, treatment, and follow-up of pediatric patients with an inflammatory brain disease in Switzerland. It was first implemented in 2020 in the pediatric clinic of the university hospital in Bern. Further centers all over Switzerland were opened for recruitment in 2021; Aarau, Basel, Bellinzona, Chur, Geneva, Lausanne, Lucerne, St. Gallen, and Zurich. The center in Winterthur is expected to be open for recruitment by autumn 2021. The registry provides data for national and international monitoring and research. It supports research on inflammatory brain diseases in Switzerland and the exchange of knowledge between clinicians, researchers, and therapists. The registry aims to improve the treatment of children with inflammatory brain diseases and optimizing their health care and quality of life.
