Abstract

Skin and soft tissue infections (SSTIs) caused by community-associated (CA)-methicillin-resistant Staphylococcus aureus (MRSA) have become a worldwide concern. An otherwise healthy 16-month-old Korean girl was admitted because of skin abscess on the left chest wall with a history of recurrent SSTIs since the age of 6 months. Immunologic evaluation including serum immunoglobulin level and nitroblue-tetrazolium (NBT) test were normal. Pus and nasal swab cultures revealed CA-MRSA ST714-SCCmec type IV with the Panton-Valentine leukocidin (PVL) genes, which was initially reported in the Netherlands in 2006 and has not been previously reported in Korea. The skin abscesses were successfully treated by needle aspiration and the use of antibiotics. In addition, nasal mupirocin was applied as a decolonization method. No more episodes of SSTI were observed over a follow-up period of 10 months.

최근 전세계적으로 지역사회 기원 메티실린내성 황색포도알균(CA-MRSA)에 의한 피부연부조직 감염증이 증가하고 있다. 16개월의 한국 여아가 생후 6개월부터 시작된 반복되는 피부연부조직 감염증을 주소로 내원하였다. 환아의 가족들도 환아와 비슷한 시기에 피부연부조직 감염증의 병력이 있었다. 환아의 혈중 면역글로불린 및 NBT 검사는 정상이었고, 피부 병변 외에는 가족 모두 건강하였다. 환아의 감염증 부위의 고름 배양 및 비강 내 보균 검사시 모두 PVL genes을 생성하는 CA-MRSA ST714 SCCmec type IV가 확인되었고, 이는 ST30의 single locus variant로서 국내에서는 보고된 적이 없는 MRSA의 유전형이다. 환아와 함께, 환아의 균주와 동일 항생제 감수성 양상을 보이는 MRSA 보균자인 환아부에게 재발 방지를 위해서 비강내 mupirocin 5일 요법을 시행하였고 이후 10개월간 추가적인 재발은 없었다.
