ABSTRACT
Rationale Initial reports during the pandemic have shown that COPD patients with COVID-19 have a poorer prognosis due to an increased risk of respiratory failure. It is well known that in COPD, there is an increased expression of angiotensin converting enzyme-2 (ACE2), the receptor which plays a role in SARS-CoV-2 entry into cells. In the absence of infection, ACE2 converts angiotensin-2 (AngII) to angiotensin-1-7- helping regulate inflammation. During COVID-19 infection, ACE2 activity is reduced due to receptor occupancy, resulting in greater levels of AngII- leading to a pro-inflammatory state. We aim to investigate the impact of COPD and COVID-19 on mortality, length of in-patient stay and gender. Method(s) A retrospective study of all in-patients aged >= 18 years with a confirmed diagnosis of COVID-19 during the first wave of the pandemic. Statistical analysis was performed using the Chi-Squared Test for independence. Result(s) 445 COVID-19 patients were included in the study, out of whom 52 (12%) had COPD. Mortality in COPD patients (65%) was found to be significantly higher than non-COPD patients (49%) (P=0.03) There were no significant differences in mortality between COPD and non-COPD patients when grouped for male and female (P=0.68). Furthermore, there were no significant differences in length of in-patient stays of >7 days between COPD and non-COPD patients (P=0.79). Conclusion(s) Our study demonstrated how COPD increases mortality in COVID-19. This data should be considered when highlighting at risk groups- prioritising them for treatment, isolation, and preventative public health measures such as the COVID-19 vaccination programme.
