초록

저자들은 평소 건강하던 젊은 여성에서 발생한 Mycoplasma pneumoniae 폐렴에서 마크로라이드 초치료에 실패한 증례를 보고한다. 환자의 객담 검체로 시행한 M. pneumoniae 23S rRNA 유전자 염기서열분석에서 마크로라이드 고도내성과 연관되어 있는돌연변이가 발견되었으며, 이 돌연변이가 치료 실패의 원인이 되었을 것으로 생각되었다. 환자는 quinolone 제제로 항균제를 변경한후 임상적인 증상과 흉부 X선에서 호전 소견을 보였으며 입원 8일째 퇴원하였다.

Abstract

We present a case of community-acquired pneumonia (CAP) that developed in a previously healthy young woman. She was diagnosed with Mycoplasma pneumoniae pneumonia, but did not respond to macrolide treatment. The pathogens of CAP was examined using chest radiographs, computed tomography, and various laboratory tests including Mycoplasma IgG and IgM antibodies, blood and sputum cultures, and PCR for M. pneumoniae, Legionella pneumophila, and Chlamydophila pneumoniae. In this study, differential diagnosis of the pathogens and analysis of the mechanisms underlying their resistance to macrolide treatment were performed, and the results were discussed. After changing the antimicrobial to quinolone, the patients’ clinical symptoms and radiographic findings improved, and she was discharged after 8 days.
