Abstract

Purpose : Although influenza is one of the most important causes of acute respiratory tract infections in children, effective antiviral therapies are not common and there are only a few clinical studies on treatment of influenza in children. We evaluated the efficacy of oseltamivir in the treatment of naturally aquired influenza in children during the first half of 2004 in Busan. Methods : From January 2004 to June 2004, throat swabs and nasal washes were performed and cultured for the isolation of influenza virus and tested by rapid antigen detection test(QuickVue influenza test) in children with suspected influenza infections. The children who responded positively to the QuickVue influenza test, we divided into two groups : an oseltamivir treatment group and a control group. We compared their clinical symptoms(including fever duration) and diagnosis. The medical records of patients with influenza virus infection were reviewed retrospectively. Results : A total of 621 individuals were suspected of influenza infection. Influenza viruses were isolated in 79(17.2 percent) out of 621 patients examined. QuickVue influenza tests were positive in 181 cases. The treatment group(83 individuals) received oseltamivir twice daily for 5 days, and the control group(99 individuals) were administered only symptom relief medicine. There was no differences between the two groups in clinical diagnosis and symptoms. Oseltamivir treatment reduced the fever duration and other respiratory symptoms. There were no adverse events associated with oseltamivir treatment. Conclusion : Our data suggest that oral oseltamivir treatment reduces the fever duration and other respiratory symptoms of acute influenza without side effects in children.

목 적 : 인플루엔자는 소아 호흡기 질환의 중요한 원인이 되고 있으며, 심각한 합병증과 사망률을 가진다. 예방 및 치료를 위해 효과적인 항바이러스제 치료가 필요하지만 소아에서 항바이러스제 치료는 일반적이지 않으며, 그에 대한 자료도 부족한 실정이다. 본 연구에서는 neuraminidase의 억제제로서 인플루엔자 A와 B 바이러스에 모두 효과를 가지는 경구 oseltamivir의 효과에 대해 연구함으로써 앞으로 소아의 인플루엔자 치료에 있어서의 도움을 제공하려 한다. 방 법 : 2004년 1월부터 6월까지 부산 메리놀병원 외래, 입원 및 응급실 방문 환아 중 인플루엔자 바이러스 감염이 의심이 되는 환아 621명에서 인후도찰물 및 콧물을 채취하여 인플루엔자 바이러스 배양을 실시하였고, QuickVue test를 시행하였다. QuickVue test에 양성을 보인 181명의 환아들을 oseltamivir를 사용한 군과 사용하지 않은 군으로 나누었고, 이들의 임상 양상과 진단을 비교함으로써 oseltamivir의 치료 효과에 대하여 후향적으로 조사, 분석하였다. 결 과 : 연구기간 동안 621명의 인플루엔자 의심 환아 중 79 명(17.2%)에서 인플루엔자 바이러스가 분리되었고, QuickVue 인플루엔자 테스트에 양성을 보인 환아는 181명이었다. QuickVue 인플루엔자 테스트에 양성을 보인 181명 중 83명에서 oseltamivir를 5일간 하루 2회 사용하여 oseltamivir 사용군으로, 98 명은 증상 완화제만을 사용하여 oseltamivir 비사용군으로 정하였다. 두 집단간에 임상 증상과 진단은 차이가 없었고, oseltamivir 사용군에서 발열 기간의 의미 있는 감소를 확인할 수 있었다. 본 연구 기간 동안에는 인플루엔자 감염으로 인해 구토나, 구역, 복통을 호소하는 경우는 있었지만, 약물 투여로 인해 이들 증상이 악화되거나, 그로 인해 약물을 중단한 경우는 1례도 없었다. 결 론 : 본 연구 결과를 통해 소아에서 인플루엔자 치료에 oseltamivir를 사용함으로써 부작용 없이 발열 기간과 다른 호흡기 증상을 감소시킬 수 있음을 알 수 있다.
