Filter by:Nitazoxanide has been shown to have a clinical efficacy against severe acute respiratory syndrome coronavirus 2; ivermectin has also demonstrated a remarkable experimental efficacy with a potential to be used for Coronavirus disease 2019.
Coronavirus Pathology is frequently associated with both diabetes mellitus and metabolic syndrome. In particular, results of observational studies and meta-analyzes configure diabetes as one of the main risk factors for the development of complications and unfavorable course of SARS (Severe Acute Respiratory Syndrome) and MERS (Middle East Respiratory Syndrome), the syndromes caused respectively by SARS- VOC coronavirus and MERS-COV coronavirus. The available data confirm this association also in the clinical picture of the infection supported by SARS-COV 2 (COVID-19). In the epidemic outbreak that erupted at the beginning of 2020 in the Lombardy Region, about two thirds of the patients who died from COVID-19 were affected by diabetes mellitus. COVID-19 occurs in 70% of cases with an inflammatory pathology of the airways that can be fed by a cytokine storm and result in severe respiratory failure (10% cases) and death (5%). At the moment, the mainly involved pathophysiological molecular mechanisms are not clearly defined. It has been hypothesized that the transmembrane glycoprotein type II CD26, known for the enzyme activity Dipeptilpeptidase 4 exerted by its extracellular domain, may play a fundamental role in this process. In addition, it is considerably expressed at the parenchyma and lung interstitium level and carries out both systemic and paracrine enzymatic activity, modulating the activity of various proinflammatory cytokines, growth factors and vasoactive peptides at the level of the deep respiratory tract. The pulmonary parenchyma and the interstitium express significantly the Dipeptilpeptidase 4 protein, which in the Middle East Respiratory Syndrome favors the entry of the virus into the cells, thus allowing the virus to replicate within the cells and thus spread throughout the cell inside the organism. Dipeptilpeptidase 4 regulates the function of bioactive peptides and above all of cytokines, vasoactive peptides and chemokines present at the level of the mesothelium, of the deep respiratory tract (alveolar epithelium and alveolar bronchus), of endothelial and immune cells triggering the inflammatory storm. In line with this evidence, it has been hypothesized that acute respiratory disease from Coronavirus may depend on the massive localization of Dipeptilpeptidase 4 in lung tissue. Furthermore, the involvement of Dipeptilpeptidase 4 in other chronic respiratory diseases has been demonstrated. Starting from these observations we hypothesized that the selective blockade of Dipeptilpeptidase 4 can favorably modulate the pulmonary inflammatory response in the subject affected by COVID-19. Among the drugs that selectively block Dipeptilpeptidase 4, the one with greater affinity precisely for Dipeptilpeptidase 4 is Sitagliptin.
SAM-COVID is a retrospective cohort study that aims to determine the impact of immunosuppressive drugs and immunoglubulins in the outcome of patients with COVID-19.
The study is a randomized controlled, open-label trial comparing subcutaneous Zilucoplan® with standard of care to standard of care alone. In the active group, Zilucoplan® will be administered subcutaneously once daily for 14 days or till discharge from the hospital, whichever comes first. The hypothesis of the proposed intervention is that Zilucoplan® (complement C5 inhibitor) has profound effects on inhibiting acute lung injury post COVID-19, and can promote lung repair mechanisms, that lead to a 25% improvement in lung oxygenation parameters. This hypothesis is based on experiments performed in mice showing that C5a blockade can prevent mortality and prevent ARDS in mice with post-viral acute lung injury. Eligible patients include patients with confirmed COVID-19 infection suffering from hypoxic respiratory failure defined as O2 saturation below 93% on minimal 2l/min O2 therapy and/or ratio PaO2/FiO2 below 350.
Neuromuscular electrical stimulation (NMES) has been considered as a promising approach for the early rehabilitation of patients in and/or after the intensive care unit (ICU). Aim of this study is to evaluate the NMES effect on physical function of COVID-19 patients.
This clinical study was designed to assess the efficacy and safety of MAS825 for the treatment of severe acute respiratory syndrome coronavirus 2 (SARS-Cov-2) infected patients with coronavirus disease 2019 (COVID-19) pneumonia and impaired respiratory function.
Novel coronavirus SARS(Severe Acute Respiratory Syndrome)-CoV-2 was first identified during the outbreak in Wuhan, China in December 2019 with the now resulting pandemic. Aggressive supportive care is the mainstay of treatment currently and rescue with lung protective mechanical ventilation is essential for survival in patients with severe acute respiratory distress syndrome. Despite supportive care, mortality is significant in hospitalized patients in the U.S., especially among patients > 65 years of age. Pharmacologic treatments to decrease disease severity are urgently needed. Hydroxychloroquine is currently widely used for treatment of autoimmune disease including systemic lupus erythematosus and rheumatoid arthritis, and it has been used to prevent and treat malaria. In vitro and in vivo antiviral activity towards SARS-CoV-2 has been reported. Since hydroxychloroquine has been used for decades its properties as a drug are well known. The investigators propose a pragmatic trial of hydroxychloroquine in moderately ill hospitalized adults with SARS-CoV-2 pneumonia with the hypothesis that hydroxychloroquine reduces severity of acute lung injury caused by SARS-CoV-2 infection.
The primary objective of this study was to evaluate if the addition of zanubrutinib to supportive care increases the respiratory failure-free survival rate at Day 28 in participants hospitalized for Corona Virus Disease 2019 (COVID-19) and pulmonary distress not receiving mechanical ventilation.

Post-discharge rehabilitation regimens for covid-19 patients have not been supported by high-quality evidence-based medical evidence.The first part of this study is a cross-sectional study.The contents of the study were the factors related to the dysfunction of COVID - 19 patients after discharge from the hospital in Wuhan.The second part of this study is a cohort study.To observe the functional changes of COVID-19 patients after discharge in hospital rehabilitation, home rehabilitation and no rehabilitation, in order to propose a more safe and effective rehabilitation program.
