Since 21, the number of patients with Japanese encephalitis (JE) in the Republic of Korea has increased. This article showed the results of the laboratory-based diagnosis of JE from 213 to 217. Real-time reverse transcription-polymerase chain reaction, enzyme-linked immunosorbent assay, indirect immunofluorescence assay, and plaque reduction neutralization test were used to detect JEV in serum and/or cerebrospinal fluid (CSF) samples. Although most JE cases showed higher antibody titers in acute and convalescent serum samples, this study focused on investigating four unusual cases. Based on these results, if the initial sample from suspected JE patients was negative for JE IgM, the second and third samples from the same patient should be obtained to accurately diagnose of JEV infection. Keywords : Japanese encephalitis, Japanese encephalitis virus, Enzyme-linked immunosorbent assay, Immunofluorescence assay, Plaque reduction neutralization test 들어가는말 일본뇌염 (Japanese encephalitis, JE) 은일본뇌염바이러스 (Japanese encephalitis virus, JEV) 에의한인수공통감염병으로, 바이러스성뇌염증상을보이며대부분아시아지역에서발생한다 [1,2]. 일본뇌염바이러스는플라비바이러스과 (family Flaviviridae) 플라비바이러스속 (genus Flavivirus) 에속하는 RNA 바이러스이며주로집모기속 (Culex genus) 모기를매개로전파된다. 돼지나물새가일본뇌염바이러스의주요증폭숙주로알려져있으며매개체인모기가그피를흡혈하고다시우연숙주인사람의피를흡혈할때바이러스가인체에침입하여감염된다 [3]. 일본뇌염은모기의활동이왕성한여름부터가을 (8월 ~11월 ) 동안주로발생하며 [4], 대부분이무증상으로지나가고 25명중 1명정도에서증상이나타난다. 약 7~14일의잠복기를거쳐고열 (39~4 ), 944

IFA) 또는플라크감소중화시험법 (Plaque reduction neutralization test, PRNT) 으로항체가상승여부를확인한다 [9](Table 1). 국내일본뇌염진단기준은 217년법정감염병진단 신고기준 의 2군감염병 ( 예방접종대상질환 ) 에따라일본뇌염에합당한임상적특징을나타내면서, 검체 ( 혈청, 뇌척수액등 ) 에서바이러스분리또는회복기혈청의항체가가급성기에비하여 4배이상증가가확인되거나특이유전자가확인되었을경우일본뇌염확진환자로판정하고있다. 그리고예방접종에의한항체가증가또는교차반응으로인해다른플라비바이러스 ( 예, 웨스트나일열바이러스 ) 감염에의한항체가증가가있을수있으므로역학적배경과임상증상을반드시고려하여, 필요시교차반응을확인하는실험을수행한다 [1,11]. 몸말 1. 일본뇌염실험실검사방법 2. 일본뇌염실험실검사현황 일본뇌염실험실검사의뢰건수는 213 년 8 건, 214 년 1,8 건, 215 년 1,118 건 216 년 1,491 건, 217 년 1,154 건으로 216 년까지는매년 증가하였으며 217 년에다소감소하였다 (Figure 1). 일본뇌염실험실 국내일본뇌염의심환자에대한실험실검사를위하여유전자검출검사 (Real-time reverse transcription-polymerase chain reaction, rrt-pcr), 항체검출검사 (Enzyme-linked immunosorbent assay, ELISA), 배양검사를수행하고있다. 검체채취일이발병일로부터 5일이내인경우유전자검출검사와항체검출검사를동시에수행하고, 검체채취일이발병일로부터 5일이후인경우항체검출검사를수행한다. 급성기혈청의항체검출검사에서 IgM 양성결과가나오면추정진단으로, 회복기혈청을요청하여두검체간간접면역형광항체법 (Indirect immunofluorescence assay, 검사의뢰건수에는뇌염증상을보이는환자의배제진단이대부분을차지하고있으며, 이중실제일본뇌염의심환자로신고된건수는 213년 32건, 214년 39건, 215년 64건, 216년 118건, 217년 143건으로보고되었다. 그리고국내일본뇌염확진환자는 213년 14건, 214년 26건, 215년 4건, 216년 28건, 217년 9건으로 213년부터 217년까지총 117건으로써, 215년까지증가하다최근 2년간감소한결과를보였다 (Figure 1). 검체종류별 ( 혈청, 뇌척수액 ) 로연도별실험실검사의뢰건수및양성건수를살펴보면, 혈청의경우 213년에실험실검사의뢰 356건중 23건, Table 1.

Annual distribution of patients with Japanese encephalitis in the Republic of Korea, *JE: Japanese encephalitis; CSF: cerebrospinal fluid 214년 515건중 65건, 215년 44건중 7건, 216년 655건중 53건, 217년 519건중 12건의양성건수가있었다. 뇌척수액의경우 213년에실험실검사의뢰 444건중 7건, 214년 565건중 21건, 215년 678건중 34건, 216년 836건중 26건, 217년 635건중 7건의양성건수가확인되었다. 상승하여일본뇌염으로확인되었다. 조사결과, 이환자는발병일 2주전에라오스해외여행력과국내일본뇌염바이러스매개모기의활동시기를감안할때, 라오스에서감염되어입국후발병한것으로추정되는해외유입의심사례로밝혀졌다. 둘째, 일본뇌염은바이러스가혈액내에서검출될수있는 기간이짧기때문에유전자검출사례가거의없는데, 215 년에 3. 일본뇌염특이사례 213년부터 217년까지일본뇌염실험실검사를통한여러사례들을살펴보면, 대부분은급성기와회복기혈청간의항체역가가상승한경우들이지만여기서는특이한사례 4가지를소개하고자한다. 첫째, 일본뇌염확진환자는대부분모기의활동시기와맞물려 8월부터 11월에대부분발생하는데 214년 1건은 5월에발생하였다. 1차혈청과 2차혈청및뇌척수액에서일본뇌염바이러스에대한 IgM 항체가검출되었고, 전체항체역가는 1:16에서 1:256이상으로 1건의유전자검출사례가있었다. 환자뇌척수액에서유전자검출을확인하였으며세포배양으로바이러스분리도성공하였다. 염기서열분석결과, 일본뇌염바이러스유전형 5형에속하는것을확인하였다. 일본뇌염바이러스는유전형이크게 5개로구분되는데 [12], 과거우리나라모기에서유전형 1형과 3형이유행하다 21년이후부터유전형 5형이확인되기시작하였다 [13,14]. 현재시판되는일본뇌염백신주는유전형 3형에속한다. 국내에서일본뇌염바이러스유전형 5형이사람에서검출된경우는이사례가첫번째로써시사하는바가크다. 향후일본뇌염바이러스유전형 3형및유전형 5형에대한특성분석및관련연구의필요성이제기된다

5 주간건강과질병 제 11 권제 29 호 셋째, 217년도에일본뇌염과웨스트나일열에대한교차반응을플라크감소중화시험법 (PRNT) 으로감별진단한사례이다. 일본뇌염 1차혈청에대한일본뇌염중화항체가 1:84, 2차혈청의일본뇌염중화항체가 1:7,878, 3차혈청의일본뇌염중화항체가 1:8,737로 4배이상의높은항체가상승을보였다. 웨스트나일열의경우 1차혈청중화항체가 1:49, 2차혈청의중화항체가 1:619로항체가가상승하였지만, 3차혈청의중화항체가 1:685로항체가상승이 2차, 3차비교시거의없어, 일본뇌염양성으로판정하였다. 일본뇌염바이러스와웨스트나일열바이러스는플라비바이러스 기술이전되어전국에서실험실검사가이루어지고있으며, 필요시추가적인확인검사는질병관리본부바이러스분석과에서수행하고있다. 213년부터 217년까지일본뇌염사례들을보면위에서언급한특이한사례들도있지만, 대부분은급성기와회복기혈청간의항체역가가상승한경우들이다. 일본뇌염확인진단을위하여일본뇌염의심환자로부터조기에적절한검체를채취하는것이중요하며, 필요할경우추가검체가확보되어실험실검사가잘이루어지도록하여야한다. 중에서도같은혈청형에속해서로교차반응을보이며이런경우 gold standard 방법인플라크감소중화시험법 (PRNT) 으로감별진단하는것이꼭필요하다 [15,16]. 넷째, 대부분의사례들은 1차검체에서 IgM 양성이면 2차검체의항체가상승으로이어져일본뇌염으로확진되지만, 이와다른결과를보이는사례가있었다. 215년사례는 1차뇌척수액에서 IgM 양성이었지만, 1차혈청에서는 IgM 음성, 2차혈청에서는 IgM equivocal( 양성과음성의경계치값 ), 3차혈청에서는 IgM 음성이나왔다. 또한플라크감소중화시험법 (PRNT) 으로확인실험을진행한결과 1:1 미만의항체가를보여최종일본뇌염음성으로판정하였다. 맺는말 29년 WHO 서태평양지역일본뇌염실험실네트워크가결성되어, 일본뇌염실험실진단체계를표준화하고이를기반으로각국의일본뇌염발생상황을정확히파악하여위험요인을분석함으로써일본뇌염퇴치에노력하고있다. 우리나라는 WHO 서태평양지역표준실험실 (Regional reference laboratory, RRL) 로지정되어일본뇌염실험실진단체계의표준화와서태평양지역내다른국가의일본뇌염확인검사를수행하는등 WHO와협력하고있다. 218년 1월부터 17개전국시 도보건환경연구원으로일본뇌염의실험실검사법 ( 유전자검출검사및항체검출검사 ) 이 참고문헌 1.

Off-line referral system for laboratory testing revealed the inconveniences that medical institutions referring their specimens were required to submit paper-based request forms. To improve this process, we newly established an on-line referral system in September 217. This article provides an overview of the entire process of the system.

29 주요통계이해하기 < 통계표 1> 은지난 5년간발생한법정감염병과 218 년해당주발생현황을비교한표로, 금주환자수 ( ) 는 218 년해당주의신고건수를나타내며, 218 년누계환자수 ( 218) 는 218년 1주부터해당주까지의누계건수, 그리고 5년주평균환자수 ( ly average) 는지난 5년 ( 년 ) 해당주의신고건수와이전 2주, 이후 2주의신고건수 ( 총 25주 ) 평균으로계산된다. 그러므로금주환자수 ( ) 와 5년주평균환자수 ( ly average) 의신고건수를비교하면해당주단위시점과예년의신고수준을비교해볼수있다. 연도별환자수 (Total no. of cases by year) 는지난 5년간해당감염병현황을나타내는확정통계이며연도별현황을비교해볼수있다. 예 ) 218 년 12 주의 5 년주평균환자수 ( ly average) 는 213 년부터 217 년의 1 주부터 14 주까지의신고건수를 총 25 주로나눈값으로구해진다. * 5 년주평균환자수 ( ly average)=(x1 + X2 + + X25)/25 1주 11주 12주 13주 14주 218년 해당주 217년 X1 X2 X3 X4 X5 216년 X6 X7 X8 X9 X1 215년 X11 X12 X13 X14 X15 214년 X16 X17 X18 X19 X2 213년 X21 X22 X23 X24 X25 < 통계표 2> 는 17 개시 도별로구분한법정감염병보고현황을보여주고있으며, 각감염병별로최근 5년누계평균환자수 (Cum, average) 와 218년누계환자수 (Cum, 218) 를비교해보면최근까지의누적신고건수에대한이전 5년동안해당주까지의평균신고건수와비교가가능하다. 최근 5년누계평균환자수 (Cum, average) 는지난 5년 ( 년 ) 동안의동기간신고누계평균으로계산된다. 기타표본감시감염병에대한신고현황그림과통계는최근발생양상을신속하게파악하는데도움이된다.
