Abstract

Purpose : Enterovirus infection is a type of viral infection that occurs relatively frequently in children during summer. It has clinical symptoms of non-specific fever, aseptic encephalomeningitis, gastrointestinal diseases, skin rash and, hand-foot-mouth disease. However, it can also occcaisionally, result in fatal symptoms like myocarditis, epicardial inflammation, transverse myelitis, quadriplegia and etc. There have been epidemic enterovirus studies, but not in the Chungnam area. Therefore, we undertook this study in order to comprehend the cause viruses in this area. Methods: We enlisted 157 children hospitalized with enteroviral infections at Soonchunhyang University hospital in Cheonan between May and August 2005. Cerebrospinal fluids or feces were collected during the acute phase after hospitalization, and observed the cytopathic effects caused by enterovirus and using reverse transcription polymerase chain reaction (RT-PCR). Results : The number of children hospitalized due to possible enteroviral infection during the period of study was 157. The number of children who tested positive with the reverse transcription polymerase chain reaction totalled 32 cases (20.4 percent). Among the children with entroviral diseases, 20 were male and 12 were female, thus the sex ratio of male to female was 1.67:1. Their clinical symptoms included fever most frequently (93.7 percent), was followed by headaches (90.0 percent), meningeal irritation signs (65.0 percent), and abdominal pain (30.0 percent). As for the type of isolated enterovirus, there were 17 cases of echovirus 18 and 6 cases of coxsackievirus B5. Furthermore, there were 2 cases of echovirus 9, 1 case of coxsackievirus A6 and coxsackievirus B3, respectively. But 5 cases were not determined by genotype. Conclusion : Echovirus 18 is circulating in Korea. We reported on identified enteroviruses, including echovirus 18, using RT-PCR in the Chungnam area during the summer of 2005.

목 적 : 장바이러스 감염은 하절기에 소아에서 비교적 흔하게 일어나는 바이러스 감염이다. 임상증상으로 비특이적인 열, 무균성 뇌수막염, 위장관 질환, 피부 발진, 수족구병 등을 일으키며 드물게 심근염, 심외막염, 횡단성 척수염, 사지마비 등 치명적으로도 나타날 수 있다. 장바이러스 유행에 대한 보고는 있었으나, 충남지역에서 장바이러스 감염에 대한 조사 및 연구 보고는 이루어지지 않고 있었다. 이에 저자들은 2005년 5월부터 8월까지 장바이러스 감염으로 의심되어 순천향대학교 천안병원에 입원한 소아를 대상으로 역전사 중합효소연쇄반응을 이용하여 원인 바이러스를 파악하고자 본 연구를 시행하였다. 방 법 : 같은 기간 순천향대학교 천안병원 소아과에 입원한 환자 중 임상적으로 장바이러스 감염이 의심되었던 환아 157명을 대상으로 입원 후 급성기에 뇌척수액 또는 분변을 채취하여 장바이러스 세포병변효과 관찰 및 역전사 중합효소연쇄반응검사를 시행하였다. 결 과 : 연구 기간동안 장바이러스 감염이 의심되어 입원하였던 환아는 157명이었고 역전사 중합효소연쇄반응 검사에서 양성을 보인 환아는 32명(20.4%)이었다. 양성 환아 중 남자가 20명, 여자가 12명으로 남녀비는 1.67:1 이었다. 이들의 임상증상은 발열이 93.7%로 가장 많았으며 두통(90.0%), 뇌막자극증상(65.0%), 복통(30.0%) 순이었다. 분리된 장바이러스는 Echovirus 18형 17례, Coxsackievirus B5형 6례 였으며, 그 외 Echovirus 9형 2례, Coxsackievirus A6형 1례, Coxsackievirus B3형 1례 분리되었으며 유전자형이 결정되지 않은 Enterovirus가 5례였다. 결 론 : 이번 연구로 Echovirus 18형을 국내 최초로 분리하였으며, 2005년 하절기에 충남지역에서 Echovirus 18형을 포함한 여러 장바이러스 감염 원인을 알 수 있었다. 향후 장바이러스 감염 환아의 진단 및 치료를 위한 지속적인 역학적 연구가 필요할 것으로 생각된다.
