Molecular Diagnosis of Coronavirus Disease 2019.

ABSTRACT: Objectives:To review molecular diagnostics for coronavirus disease 2019. The world is in the midst of a coronavirus disease 2019 pandemic. Containing the spread of the severe acute respiratory distress coronavirus is critical. Instrumental to the future success is the ability to reliably and reproducibly detect this inciting pathogen to inform public health containment policies and treatment decisions. Data Sources:Molecular diagnostics focusing on molecular detection methodologies for detection of the virus and the presence of the disease. Study Selection:Narrative review. Data Extraction:Literature, PubMed, Scopus, and official government documents. Data Synthesis:Diagnosing severe acute respiratory syndrome coronavirus is done through real-time reverse transcriptase-polymerase chain reaction tests, cell culture, and serology. For patients, diagnostics are an integral part of a full medical history, physical examinations, blood tests, and diagnostic imaging. Conclusions:Here, we review current approaches to the molecular diagnosis of coronavirus disease 2019.

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.
