Abstract

In December 2019, the coronavirus disease 2019 (COVID-19) caused by the virus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) emerged in China and spread rapidly around the world, infecting millions of people. Cases of COVID-19 infection were observed to lead to viral pneumonia. Thirty-five patients admitted to the Gyeonggi Medical Center, South Korea, between November 2020 to January 2021, were found to have been infected with the influenza virus A and B, which cause symptoms similar to COVID-19. The records of these patients and those of COVID-19 patients who visited the hospital for medical examination were compared. The study patients included thirty patients with COVID-19 and/or influenza, five of those with influenza alone. A group of 121 patients without infection was used as control. Patients with COVID-19 and influenza had significantly higher lactate dehydrogenase levels than the patients with COVID-19 alone. The erythrocyte sedimentation rate (ESR) was higher in patients with COVID-19 alone than in other groups. Significant clinical outliers were observed in the COVID-19 and influenza infection group compared with the COVID-19 alone group. These results are expected to play an important role in the analysis of the hematological data of infected patients and the comparison of simultaneous and single infection data to determine clinical symptoms and other signs. These results may also assist in the development of vaccines and treatments for COVID-19.

2019년 12월 중국에서 바이러스성 폐렴을 일으키는 코로나 바이러스 질병 2019 (COVID-19)가 검출돼 전 세계로 빠르게 확산되어 수백만 명의 감염자와 사망자가 발생했다. 증상이 유사한 호흡기 바이러스 가운데 경기도의료원에 입원한 환자 35명이 2020년 11월부터 2021년 1월까지 인플루엔자 바이러스(인플루엔자바이러스 A·B)에 감염된 것으로 나타났다. 이들 환자의 기록과 건강검진을 위해 병원을 찾은 환자의 기록을 비교했다. 대상 환자 군에는 COVID-19 환자 30명, 인플루엔자 환자 5명, 비 감염 환자 121명이 포함됐다. 혈액학적 기록을 활용해 입원 당일 실시한 일반 혈액 검사와 생화학 검사 결과를 분석했다. COVID-19 및 인플루엔자에 동반 감염된 환자들은 단일 COVID-19 감염 그룹보다 젖산 탈수소효소(LDH), C-반응 단백질(CRP), 백혈구(WBC) 수치가 유의미하게 높았다. 적혈구 침전률과 COVID-19 감염 환자만 있는 림프구(Lymphocyte)가 다른 그룹에 비해 증가했다. 인플루엔자 감염군은 COVID-19와 인플루엔자에 동반 감염된 환자에 비해 발열의 빈도가 빈번했다. COVID-19에 감염된 단일 환자에 비해 공동 감염 그룹에서 유의미한 임상 특이 수치가 관찰되었다. 본 연구에서 나오는 결과로 COVID-19치료제와 백신개발에 이용하기를 기대한다.
