코로나 바이러스 감염증-19 (coronavirus disease-19, COVID-19)는 제2형 중증급성호흡기증후군 코로나 바이러스(severe acute respiratory syndrome coronavirus-2, SARS-CoV-2) 감염에 의한 질환으로 2022년 6월 초까지 전 세계적으로 5억 명이 넘게 감염되었고 그중 630만여 명이 이 질환으로 사망하였다[1]. COVID-19는 또한 매우 다양한 임상증상을 보인다. 대표적인 증상으로는 발열, 기침, 호흡곤란, 인후통과 같은 호흡기계 감염과 미각 및 후각의 소실, 피로, 근육통, 등과 같은 비특이적인 증상을 동반하기도 한다[3]. 많은 환자들은 COVID-19 감염 완치 후에도 여러 신체적·정신적·심리적 후유증을 겪기도 한다[4,5] 대부분의 COVID-19 감염 관련 연구는 주로 COVID-19 감염 후의 폐기능 저하 및 임상적 분류등이였으나, COVID-19 감염 전· 후 폐기능검사 결과를 토대로 한 폐기능에 대한 논문을 찾아보기 어려웠다. 본 논문에서는 COVID-19 감염전 폐기능 검사의 결과와 COVID-19 감염 후의 폐기능 검사결과값을 비교하여 COVID-19 감염이 건강한 성인의 폐기능에 영향을 주는가에 대해 알아보고자 한다. COVID-19 감염 전· 후의 1초간 노력성폐활량(FEV1), COVID-19은 감염 전과 비교하였을 때 74%로 감소하였다. COVID-19 감염 전 1초율(Perccent of FEV1/FVC)는 75%, 감염 후 1초율은 74%로 감염 전보다 감소하였으나, 감염전· 후의 1초율은 정상에 속한 것을 알 수 있었다. 노력성폐활량(FVC) 검사의 결과를 비교하였을 때 감염 후 FVC의 값은 86%로 감염 전 87%에 비해 감소하였다. 본 연구결과 건강한 성인의 COVID-19감염 전·후의 폐기능을 비교한 결과 COVID-19 바이러스가 폐기능에 영향을 주는 것으로 나타났다.
Coronavirus infection-19 (COVID-19) is a disease caused by a type 2 severe acute respiratory syndrome coronavirus-2, SARS-CoV-2 infection, of which more than 500 million people worldwide died by early June 2022, of which more than 630 people died. COVID-19 also has a wide variety of clinical symptoms. Typical symptoms include respiratory infections such as fever, cough, shortness of breath, and sore throat, as well as non-specific symptoms such as loss of taste and smell, fatigue, muscle pain, etc. Many patients also suffer from various physical, mental, and psychological aftereffects even after complete recovery of COVID-19 infection. Most of the COVID-19 infection-related studies were mainly lung function degradation and clinical classification after COVID-19 infection, but it was difficult to find a paper on lung function based on the results of lung function tests before and after COVID-19 infection. In this paper, we would like to compare the results of the lung function test before COVID-19 infection with the results of the lung function test after COVID-19 infection to find out whether COVID-19 infection affects the lung function of healthy adults. Effortful lung capacity (FEV1,) for 1 second before and after COVID-19 infection, COVID-19 decreased to 74% compared to before infection. The first second rate before and after COVID-19 infection (Percent of FEV1,/FVC) was 75%, and the first second rate after infection was 74%, down from before and after infection, but the first second rate before and after infection was found to be normal. When comparing the results of the effortless lung capacity (FVC) test, the value of FVC after infection was 86%, down from 87% before infection. As a result of this study, it was found that the COVID-19 virus affects lung function before and after COVID-19 infection in healthy adults.
