Panton-Valentine leucocidin (PVL) toxin-producing strains of Staphylococcus aureus (S. aureus) are associated with skin abscesses and furunculosis, with necrotizing pneumonia being a relatively rare problem. Here, we describe a fatal case of necrotizing pneumonia in a 14-year-old child who presented initially with sore throat and pyrexia. He deteriorated rapidly, developing hypotension, multiple organ failure and purpura fulminans. S. aureus was isolated from the tracheal aspirate, which was found to be positive for PVL, toxic shock syndrome toxins (TSST) 1 and 2 and staphylococcal enterotoxin C (SEC). It was postulated that purpura fulminans and toxic shock syndrome were a result of the abovementioned exotoxins.
This case highlights the emergence of PVL-positive community-acquired S. aureus infection and association of purpura fulminans with superantigens. Practitioners should be aware of this illness in order to initiate appropriate treatment.
产生杀白细胞素(PVL)毒素的金黄色葡萄球菌菌株与皮肤脓肿和疖病有关,坏死性肺炎是相对罕见的问题。在此,我们描述了一名14岁儿童坏死性肺炎的致死病例,该患儿最初表现为咽痛和发热。他病情迅速恶化,出现低血压、多器官功能衰竭和暴发性紫癜。从气管吸出物中分离出金黄色葡萄球菌,发现其PVL、中毒性休克综合征毒素(TSST)1和2以及葡萄球菌肠毒素C(SEC)呈阳性。据推测,暴发性紫癜和中毒性休克综合征是上述外毒素所致。
该病例凸显了PVL阳性社区获得性金黄色葡萄球菌感染的出现以及暴发性紫癜与超抗原的关联。从业者应了解这种疾病以便启动适当治疗。
