Introduction

The prevalence of asthma in patients hospitalized with SARS-CoV-2 has been studied and varies widely in the different series. However, the prevalence in SARS-infected patients not requiring hospitalization is not known. The objective of this study was to analyze the presence of asthma in a consecutive series of patients who tested positive in the RT-PCR assay for SARS-CoV-2 and did not require hospital admission.

Methods and results

A total of 218 patients (58% of those who tested positive) did not require hospitalization; they had a median age of 45 years (IQR 34–57) and 57% were female. Six patients (2.8%) had a previous diagnosis of asthma. Only one patient developed a mild aggravation of asthma symptoms associated with SARS-CoV-2 infection.

Conclusions

Few patients with asthma were infected by SARS-CoV-2, and this infection was not a significant cause of asthma exacerbation.

通过 RT-PCR 检测不需要住院的 SARS-CoV-2 感染患者的哮喘患病率。

介绍

SARS-CoV-2 住院患者的哮喘患病率已经过研究，并且在不同系列中差异很大。然而，不需要住院治疗的 SARS 感染患者的患病率尚不清楚。本研究的目的是分析在 SARS-CoV-2 RT-PCR 检测中呈阳性且不需要住院的一系列连续患者中是否存在哮喘。

方法和结果

共有 218 名患者（占检测阳性患者的 58%）不需要住院；他们的中位年龄为 45 岁 (IQR 34–57)，57% 为女性。6 名患者 (2.8%) 之前被诊断为哮喘。只有一名患者出现与 SARS-CoV-2 感染相关的哮喘症状轻度加重。

结论

很少有哮喘患者感染 SARS-CoV-2，这种感染不是哮喘恶化的重要原因。
