Meta AnalysisPrevalence of Comorbid Asthma and Related Outcomes in COVID-19: A Systematic Review and Meta-Analysis.
The impact of asthma on coronavirus disease 2019 (COVID-19) remains largely unknown. ⋯ There is great variability in asthma prevalence among patients with COVID-19 in different countries or regions. Asthma is not associated with higher COVID-19 severity or worse prognosis, and patients with asthma are found to have a lower risk of death compared with patients without asthma.

Predictive Nomogram for Severe COVID-19 and Identification of Mortality-Related Immune Features.
Patients with severe 2019 novel coronavirus disease (COVID-19) have a high mortality rate. The early identification of severe COVID-19 is of critical concern. In addition, the correlation between the immunological features and clinical outcomes in severe cases needs to be explored. ⋯ The novel nomogram aided the early identification of severe COVID-19 cases. In addition, the abundance of CD45RO+CD3+ T cells and neutrophil-to-lymphocyte and neutrophil-to-natural killer cell ratios may serve as useful prognostic predictors in severe patients.

Meta AnalysisAntineutrophil Cytoplasmic Antibodies and Organ-Specific Manifestations in Eosinophilic Granulomatosis with Polyangiitis: A Systematic Review and Meta-Analysis.
Eosinophilic granulomatosis with polyangiitis (EGPA), also known as Churg-Strauss syndrome, is a rare and often severe systemic vasculitis associated with antineutrophil cytoplasmic antibodies (ANCAs). EGPA can affect multiple organ systems, but the relationships between ANCA status and the organ-specific manifestations of EGPA in previous reports were inconsistent. ⋯ This study provides more evidence that patients with EGPA may exhibit different features of disease based on their ANCA status.
