초록

매년 호흡기 바이러스 감염으로 인해 수 백만명의 소아들이 사망한다. 호흡기 바이러스 감염의 원인 병원체 중 Human rhinovirus (HRV)는 코감기의 주요 원인 균으로 면역력이 약한 영, 유아, 노인 그리고 천식 환자에게 심각한 호흡기 감염의 원인으로 작용하는 병원체이다. 2012년 1월부터 2018년 12월까지 천안 단국대학교 병원 진단검사의학과에 호흡기 바이러스 검사가 의뢰된 호흡기 검체 9,010개의 검체를 real time reverse transcription PCR (real time RT-PCR) 방법으로 검사했다. 총 12종의 호흡기 바이러스를 real-time RT-PCR로 검출했다. 연구기간 중 평균 검출률은 21.3%이었고, HRV 양성 환자의 평균 연령은 6.5세였다. 7월의 검출률이 32.4%로 가장 높게 나타났고 2월이 8.3%로 가장 낮았다. 연령대별로 검출률을 분석해봤을 때 10세 미만의 검출률이 가장 높았다. HRV의 중복 감염률은 35.3%이고, 가장 흔한 조합은 Adenovirus와의 조합이었다. 호흡기 바이러스 감염증은 비슷한 임상 증상을 가지고 있어 빠른 진단이 이루어 져야 적절한 시기에 적절한 치료를 할 수 있다. 호흡기 바이러스 감염은 보통 면역력이 약한 어린아이와 노인에서 주로 발생하는 것으로 알려져 있다. 하지만 본 연구에서는 10세 미만에 이어 10대 환자들의 검출률이 높았다. 그리고 1,2월을 제외하고 15% 이상의 detection rate를 보였다. HRV의 감염 양상에 대한 꾸준한 연구가 필요할 것으로 사료된다.

Annually, millions of children die from respiratory virus infections. Human rhinovirus (HRV) is a causative agent of severe respiratory infections in young, elderly, and asthmatic patients with weak immunity. In this study, 9,010 respiratory virus specimens were collected from January 2012 to December 2018 at Dankook University Hospital, Cheonan and examined by real-time reverse transcription polymerase chain reaction. Twelve respiratory viruses were detected. The mean detection rate was 21.3% (N=1,920/9,010), and the mean age of HRV-positive patients was 6.5 years (median age: 1.6 years, range: 0.0~96.0). The detection rate was the highest in July (32.4%) and the lowest in February (8.3%). When the detection rate was analyzed by age group, the detection rate was the second highest in patients aged 10~19 years. The co-infection rate of HRV was 35.3%, and the most common combination was with Adenovirus. Respiratory virus infections are known to occur in children and elderly people with weak immunity. However, in this study, the detection rate was second highest in patients aged 10~19 years. Indeed, the detection rate in this age group was more than 15%, except in January and February. These results suggested that steady-state studies on the infection patterns of HRV are required.
