Novel coronavirus treatment with ribavirin: Groundwork for an evaluation concerning COVID-19.

ABSTRACT: Confronting the challenge of the outbreak of COVID-19 should sharpen our focus on global drug access as a key issue in antiviral therapy testing. The testing and adoption of effective therapies for novel coronaviruses are hampered by the challenge of conducting controlled studies during a state of emergency. The access to direct antiviral drugs, such as ribavirin, that have an existing inventory and reliable supply chain may be a priority consideration for therapies developed for the 2019-nCoV infection outbreaks and any strain variants that may emerge. On the basis of the direct antiviral activity of ribavirin against 2019-nCoV in vitro and evidence for potency enhancement strategies developed during the prior SARS and MERS outbreaks, ribavirin may significantly impact our ability to end the lingering outbreaks in China and slow outbreaks in other countries. The apparent COVID-19 pandemic provides an opportunity to follow dosage guidelines for treatment with ribavirin, test new therapeutic concepts, and conduct controlled testing to apply the scientific rigor required to address the controversy around this mainstay of antiviral therapy.

Project description:BackgroundWhile the 2019 novel coronavirus disease (COVID-19) outbreak has been largely kept under control in China, it remains a global pandemic, and the source, transmission route, and treatments of SARS-COV-2 are still being investigated. Here, we summarized the clinical features, diagnosis, treatment, and prognosis of COVID-19 patients based on our clinical practice.MethodsThe clinical and imaging findings, treatments, and follow-up data of 471 patients with COVID-19 who were discharged from the Wuhan Jinyintan Hospital prior to February 6, 2020, were retrospectively analyzed.ResultsAmong these patients, there were 2 mild cases, 282 moderate cases, 181 severe cases, and 6 critical cases. There were 250 males and 221 females aged 17 to 90 years. The median age was 54 years in the severe/critical group, which was significantly older than in the mild/moderate group (P<0.05). 44.59% of them had one or more underlying diseases. The most common symptoms were fever, cough, expectoration, and dyspnea. The median body temperature in the severe/critical group was 39°C, which was significantly higher than in the mild/moderate group (P<0.05). The incidences of lymphopenia and CD4+ T lymphocytopenia were 53.5% and 41.86%, respectively. Ground-glass opacity and small patchy shadows were the most common findings on chest computed tomography (CT). Compared with the mild/moderate group, the severe/critical group showed higher proportions of severe lymphocytopenia and CD4+ T lymphocytopenia, along with more ground-glass shadows and large-scale consolidation. After anti-infection, oxygen therapy, and symptomatic support, lymphocytes and CD4+ T lymphocytes were markedly increased, all patients were discharged. The median time of nucleic acid conversion and hospital stay were 9 and 12 days, respectively, which were significantly longer in the severe/critical group than in the mild/moderate group. Of the 390 cases followed, only 19 were hospitalized again due to other diseases. All patients recovered well from COVID-19, with negative nucleic acid test results.ConclusionsLymphocytopenia and CD4+ T lymphocytopenia were found to be associated with COVID-19 and thus may be important indicators in evaluating the severity and prognosis. Multidisciplinary management including antiviral treatment, immune regulation, and symptomatic support is effective, and yields a low recurrence rate.
