This study is a double-blind, randomized, placebo-controlled study to evaluate the efficacy and safety of FB2001 in hospitalized patients with moderate to severe Coronavirus Disease 2019 (COVID-19). A total of about 1188 subjects are planned to be enrolled. The subjects will be randomized in a 1:1 ratio to FB2001 group or placebo group while both receiving standard of care treatment.
Chronic olfactory dysfunction from the COVID-19 pandemic is a growing public health crisis with up to 1.2 million people in the Unites States affected. Olfactory dysfunction impacts one's quality of life significantly by decreasing the enjoyment of foods, creating environmental safety concerns, and affecting one's ability to perform certain jobs. Olfactory dysfunction is also an independent predictor of anxiety, depression, and even mortality. While the pandemic has increased the interest by the scientific community in combating the burgeoning health crisis, few effective treatments currently exist for olfactory dysfunction. Furthermore, patients impacted by "long COVID," or chronic symptoms after an acute COVID-19 infection, experience impairments other than olfactory and gustatory dysfunction, such as chronic dyspnea, impaired memory and concentration, and severe fatigue. These symptoms have been hypothesized to be a result of sympathetic positive feedback loops and dysautonomia. Stellate ganglion blocks have been proposed to treat this hyper-sympathetic activation by blocking the sympathetic neuronal firing and resetting the balance of the autonomic nervous system. Studies prior to the COVID-19 pandemic have supported a beneficial effect of stellate ganglion blocks on olfactory dysfunction, and recent news reports and a published case series have described a dramatic benefit in both olfactory function and other long COVID symptoms in patients receiving stellate ganglion blocks. Therefore, we propose a single cohort prospective study to generate pilot data on the efficacy and safety of sequential stellate ganglion blocks for the treatment of COVID-19-induced olfactory dysfunction and other long COVID symptoms.
"Long-COVID'' (also known as post-COVID-19 syndrome, post-acute sequelae of COVID-19, or chronic COVID syndrome, used here as 'Long-COVID' for brevity), is a complex array of postconvalescence symptoms following SARS-CoV-2 infection. The syndrome, common in COVID-19 survivors, can affect every organ system through as-yet uncharacterised but presumed immunological mechanisms. Prevalence depends on the definition used and time-period of follow-up, as well as the population being studied. The syndrome has been associated with significant and persistent disability in some survivors but has been hampered, until recently, by lack of a clinical definition, diagnostic criteria, and objective measures of disease or disability [1]. A Delphi-informed initial World Health Organisation (WHO) clinical definition was released in early October 2021 but has attracted much criticism from both clinicians and survivors for a host of reasons, ranging from a lack of precision to a lack of inclusion [2]. Further complicating the syndrome is the context in which the SARS-CoV-2 epidemic occurred, which was associated with severe lockdowns in many countries (including South Africa) with social isolation, widespread fear and disinformation, widespread economic hardship, and loss of family and acquaintances, all of which contribute to symptoms (psychiatric and sleep disturbances, pain, and other syndromes) reported to be associated with Long-COVID. Finally, many Long-COVID symptoms overlap with those seen in patients hospitalised for any severe illness, especially those admitted to intensive care and ventilated. However, the proliferation of literature reporting associations of Long-COVID symptoms with more severe COVID-19 disease, and objective immunological, radiological, and organ-specific dysfunction in those reporting symptoms, suggests that the entity is real. The pathogenesis of Long-COVID is poorly understood, but this association with more severe disease - where immune dysregulation plays a major role in those with hospitalization, respiratory failure, and death - suggests an immune-mediated inflammatory dysfunction that may impact all organs [3-14]. The sheer rapidity of four major infection waves in South Africa, the initial focus on containing the hospital burden of those with severe illness, and subsequent emphasis on the roll-out of a mass vaccination program, has left little space for studying SARS-COV-2 sequalae in survivors. This group, loosely and inaccurately termed "recovered'' in South African reporting, were largely unvaccinated or partly vaccinated at the time of infection, leaving them at risk of developing Long-COVID.
PAX is a prospective, randomized (1:1), double-blind, placebo-controlled study, that have as a objective to evaluate the safety and tolerability of plasma exchange (PE) in patients with Post Acute Covid-19 Syndrome (PCC) comparing to sham plasma exchange. The participants will be randomized in two arms: (1) 6 sessions of PE (Plasma Exchange) with human serum albumin 5% or (2) 6 sessions with placebo (infusion of of sterile saline solution 0.9%) on days 1, 3, 8, 10, 15 and 17.
SARS-CoV-2 (Severe acute respiratory syndrome coronavirus type 2) is a new coronavirus and identified causative agent of COVID-19 disease. These viruses predominantly cause mild colds, but can sometimes cause severe pneumonia and pulmonary skeletal changes. By low-field gastric magnetic resonance imaging (NF-MRI), only a small number of structural, scarring changes were seen in a preliminary study of pediatric and adolescent patients with past SARS-CoV-2 infection. In contrast, however, extensive changes in ventilation and blood flow function of the lungs were seen. The long-term consequences and spontaneous progression of these changes on imaging are completely unclear. The aim of this study is to assess the course of these functional lung changes in pediatric and adolescent patients and to validate them with other standard clinical procedures.
A new coronavirus, the third documented animal-to-human passage, emerged in Wuhan , China in the last quarter of 2019. Acne patients on doxycycline escaped seasonal viruses, showing the interest of this antibiotic as a possible treatment against COVID-19. The antiviral action of tetracyclines can be explained by different mechanisms. First of all, tetracyclines are modulators of innate immunity by decreasing NF-B expression, inhibiting inflammatory cytokines such as TNF-α, IL-1β and IL-6, inflammatory granulomas and free radical release . This action is obtained at doses lower than those necessary to obtain an antibiotic effect. Another possible action of tetracyclines is their ability to chelate zinc from matrix metalloproteinases (MMPS). The coronavirus family is known to bind to host MMPs, particularly for viral survival. Their chelating activity may help inhibit SARS-CoV-2 infection by limiting its ability to replicate in the host. Finally, tetracyclines could have a direct action by inhibiting the replication of single-stranded RNA virus, such as the SARS-CoV-2 coronavirus.We therefore propose a larger comparative study using data from the French National Health Data System.
