We describe a rare case of Propionibacterium acnes native-valve endocarditis that silently progressed in a 67-year-old man with hybrid dialysis. The patient was scheduled for kidney transplantation, and pre-operative investigation incidentally detected a vegetative structure at his native mitral valve that had increased in size. He underwent cardiac surgery and P. acnes was detected in cultures of a resected cardiac valve specimen and blood. This case highlights that P. acnes can silently cause infective endocarditis in a native-valve, and that physicians should consider the possibility of infection when P. acnes is isolated in blood cultures.
我们描述了一例罕见的痤疮丙酸杆菌所致自体瓣膜心内膜炎病例，该病例在一名接受混合透析的67岁男性患者中悄然进展。该患者计划进行肾移植，术前检查偶然发现其原生二尖瓣处有一个增大的赘生物。他接受了心脏手术，在切除的心脏瓣膜标本和血液培养物中检测到痤疮丙酸杆菌。该病例突出表明，痤疮丙酸杆菌可在自体瓣膜中悄然引起感染性心内膜炎，并且当血培养中分离出痤疮丙酸杆菌时，医生应考虑感染的可能性。
