초록
목적: 급성 위장염의 대부분의 경우 원인 병원체가 확인되지 않는다. 최근 들어 발달한 multiplex reverse transcriptase-polymerase chain reaction (RT-PCR) 검사는 장염 병원체 검출에 도움을 줄 수 있다. 이 연구는 multiplex RT-PCR을 이용해, 소아 장염환자에서 병원체의 역학을 조사하고자 하였다. 방법: 2015년 5월부터 2018년 6월까지 대한민국 서울의 2차병원에서 급성 위장염으로 진단받은 소아 환자의 대변에서 병원체를 확인하기 위해 multiplex RT-PCR 검사를 시행하였다. 결과: 바이러스 병원체에 대한 1,366개의 대변 검체 중, 483개(35.3%)에서 1개 이상의 병원체가 분리되었다. A군 로타바이러스는 106건(7.8%)에서 확인되었으며, 양성률은 3.0% (8/263)에서 16.7% (48/288)까지 매년 증가했다(P<0.001). 노로바이러스 GII는 가장 흔한 바이러스성 병원체였고(263/1366, 19.3%), 3년간 양성률은 증가하지 않았다. 세균성 병원체에 대한 304개의 대변 검체 중 캄필로박터(32/304, 10.5%)는 가장 흔한 세균성 병원체였으며, 그 다음으로 Clostridium difficile (toxin B) (22/304, 7.2%), 살모넬라균(17/304, 5.6%)이었다. 이 균들의 양성률은 연구기간 동안 증가하지 않았다. 결론: 로타바이러스 백신 도입 이후 노로바이러스 GII가 소아 장염에서 주요한 병원체였지만, 연구기간 동안 로타바이러스 감염 환자가 증가했고, 특히 2018년에는 급증했다. 따라서 새로운 로타바이러스 균주의 등장 가능성을 포함한 추가 연구가 필요하다. 캄필로박터는 소아 세균성 장염의 주요 원인이며, 적절한 치료를 위해 이 균의 임상적 특성을 고려하고 지속적 감시가 필요하겠다.
Abstract
Purpose: The multiplex reverse transcriptase-polymerase chain reaction (RT-PCR) test developed recently can help detect enteric pathogens of acute gastroenteritis (AGE). This study aimed to investigate the epidemiology of pathogens in children with AGE using the multiplex RT-PCR. Methods: From May 2015 to June 2018, multiplex RT-PCR tests were performed to identify pathogens in the feces of pediatric patients diagnosed with AGE at a secondary hospital in Seoul, Korea. Results: Of the 1,366 stool samples examined for viral pathogens, 483 (35.3%) tested positive for ≥1 pathogen. Group A rotavirus (RV) was detected in 106 cases (7.8%). The positivity rate increased annually from 3.0% (8/263) to 16.7% (48/288) and surged in 2018 (P<0.001). Norovirus (NoV) GII was the most common viral pathogen (263/1,366, 19.3%), and the positivity rate did not increase during the 3 years. Of the 304 stool samples tested for bacterial pathogens, Campylobacter spp. was the most common bacterial pathogen (32/304, 10.5%), followed by Clostridium difficile (22/304, 7.2%) and Salmonella spp. (17/304, 5.6%). The positivity rate of these bacterial pathogens did not change significantly during the study period. Conclusions: NoV GII is the main pathogen in childhood AGE since the introduction of RV vaccine, yet the number of rotavirus-infected patients increased during our study, especially in 2018. Therefore, further research is needed including the possibility of emergence of novel RV strains. Campylobacter spp. is the predominant cause of bacterial AGE in children. For proper treatment, the clinical characteristics of the bacteria should be taken into consideration, and continuous monitoring is necessary.
