          Abstract

          Background

          COVID-19 emerged as a pandemic toward the end of 2019, causing large numbers of people to become infected and die.

          Objective

          To determine whether allergic diseases are a risk factor for hospitalization in COVID-19.

          Methods

          We conducted a study including 107 pediatric patients after COVID-19 recovery. ISAAC Phase 3 questionnaires were distributed together with a detailed history of environmental factors and an allergic evaluation including skin prick tests, specific IgE tests, and spirometry. We investigated the prevalence of allergic diseases and evaluated the factors associated with hospitalization in COVID-19.

          Results

          Sixty-one (57%) patients were hospitalized and 46 (43%) patients were followed closely in the outpatient clinic. The prevalence of allergic rhinitis (AR ), recurrent wheezing, atopic dermatitis (AD), and asthma was 10.3%, 5.5%, 4.7%, and 3.7%, respectively, within the whole study population. While having asthma ± AR, AD, and passive tobacco exposure were not found to be related to hospitalization due to COVID-19, having a pet at home was found to be decreased risk of hospitalization (OR: 0.191, 95% CI: 0.047-0.779, p = 0.021). Spirometry tests revealed a higher FEV1/FVC ratio and a PEF reversibility in hospitalized patients compared to nonhospitalized ones (p = 0.023 and p = 0.003, respectively).

          Conclusion

          Asthma and allergic diseases do not appear to be risk factors for hospitalization due to COVID-19 in children, and having a pet at home can be a protective effect. Pulmonary function testing seems to be important for monitoring lung damage following COVID-19.

            The species Severe acute respiratory syndrome-related coronavirus : classifying 2019-nCoV and naming it SARS-CoV-2

            The present outbreak of a coronavirus-associated acute respiratory disease called coronavirus disease 19 (COVID-19) is the third documented spillover of an animal coronavirus to humans in only two decades that has resulted in a major epidemic. The Coronaviridae Study Group (CSG) of the International Committee on Taxonomy of Viruses, which is responsible for developing the classification of viruses and taxon nomenclature of the family Coronaviridae, has assessed the placement of the human pathogen, tentatively named 2019-nCoV, within the Coronaviridae. Based on phylogeny, taxonomy and established practice, the CSG recognizes this virus as forming a sister clade to the prototype human and bat severe acute respiratory syndrome coronaviruses (SARS-CoVs) of the species Severe acute respiratory syndrome-related coronavirus, and designates it as SARS-CoV-2. In order to facilitate communication, the CSG proposes to use the following naming convention for individual isolates: SARS-CoV-2/host/location/isolate/date. While the full spectrum of clinical manifestations associated with SARS-CoV-2 infections in humans remains to be determined, the independent zoonotic transmission of SARS-CoV and SARS-CoV-2 highlights the need for studying viruses at the species level to complement research focused on individual pathogenic viruses of immediate significance. This will improve our understanding of virus–host interactions in an ever-changing environment and enhance our preparedness for future outbreaks.

              Risk factors for severity and mortality in adult COVID-19 inpatients in Wuhan

              Background In December 2019, COVID-19 outbreak occurred in Wuhan. Data on the clinical characteristics and outcomes of patients with severe COVID-19 are limited. Objective The severity on admission, complications, treatment, and outcomes of COVID-19 patients were evaluated. Methods Patients with COVID-19 admitted to Tongji Hospital from January 26, 2020 to February 5, 2020 were retrospectively enrolled and followed-up until March 3, 2020. Potential risk factors for severe COVID-19 were analyzed by a multivariable binary logistic model. Cox proportional hazard regression model was used for survival analysis in severe patients. Results We identified 269 (49.1%) of 548 patients as severe cases on admission. Elder age, underlying hypertension, high cytokine levels (IL-2R, IL-6, IL-10, and TNF-a), and high LDH level were significantly associated with severe COVID-19 on admission. The prevalence of asthma in COVID-19 patients was 0.9%, markedly lower than that in the adult population of Wuhan. The estimated mortality was 1.1% in nonsevere patients and 32.5% in severe cases during the average 32 days of follow-up period. Survival analysis revealed that male, elder age, leukocytosis, high LDH level, cardiac injury, hyperglycemia, and high-dose corticosteroid use were associated with death in patients with severe COVID-19. Conclusions Patients with elder age, hypertension, and high LDH level need careful observation and early intervention to prevent the potential development of severe COVID-19. Severe male patients with heart injury, hyperglycemia, and high-dose corticosteroid use may have high risk of death.
