Effect of chronic obstructive pulmonary disease and smoking on the outcome of COVID-19

A study has been published today as a fast-track article for the IJTLD, investigating the association between chronic obstructive pulmonary disease (COPD), smoking and the potential for poor outcomes in patients with COVID-19.

The COVID-19 pandemic has continued to spread worldwide, and although most people are asymptomatic or only display a mild, flu-like illness, a significant proportion develop a severe response. It is of great importance to find risk factors or comorbidities associated with severe COVID-19 to protect the vulnerable and allow for prudent resource allocation.

Due to the large number of smokers, a slight increase in risk would have a significant impact on public health. Also, COPD has been shown to increase the severity of COVID-19 and tobacco smoking is one of the leading causes of COPD.

This study performed a systematic literature search of the major databases and an analysis of the data. This systematic review and meta-analysis revealed that COPD and smoking were associated with poor outcomes in patients with COVID-19, and that the overall association with poor outcome was stronger for COPD than for smoking.
