Chronic obstructive pulmonary disease (COPD) is a common lung disease that is considered the leading cause of death in the world after cardiovascular disease and malignancies. Therefore, it is important to investigate whether this disease increases the risk of infection with SARS-CoV-2 and what are the clinical outcomes of coronavirus disease 2019 (COVID-19). Since both diseases affect the respiratory tract, the purpose of this review diploma thesis was to determine whether there is an interrelationship between COPD and COVID-19 disease. The main objectives of this diploma thesis were to investigate whether COPD patients are at increased risk of SARS-CoV-2 infection, how this disease affects clinical outcomes, whether prescribed therapy can be continued or should be modified in COPD patients, and the importance of educating COPD patients about protective measures against COVID-19. Currently, it is not clear whether COPD patients are at higher risk of SARS-CoV-2 infection; however, it is confirmed that there is a higher rate of hospitalisation and death. COPD patients should continue prescribed COPD therapy even if they have COVID-19 because it is not confirmed that taking these medications changes the clinical outcomes of COVID-19 infection. Protective measures are very important in times of higher prevalence of COVID-19 because they reduce the risk of infection and help COPD patients maintain their health. Physicians and pharmacists should educate patients and warn them about increased spread of the virus when using inhalers and performing tests such as spirometry. Health care workers should be available to patients in a variety of alternative ways as patient care has been minimized in the doctor’s office.
