背景:Lawsonellaclevelandensis是最近记录的一种厌氧菌,部分耐酸。然而,很少发现它与人类感染有关,特别是在我们的患者进行自体脂肪移植隆胸之前的整形和整容手术范围内。隆胸越来越流行,最常见的术后并发症是细菌感染。
方法:一名29岁女性,在自体脂肪移植隆胸手术后发现她的右乳房肿胀和发热。在管理之前,她接受抗生素治疗(细节不详)超过1个月,但无任何显著改善.给药后,她接受了静脉注射抗生素的经验性治疗,并通过Vaccuum密封引流(VSD)进行了反复清创术。并将手术中收集的坏死组织和脓液样本送去进行微生物检测。然而,常规检查失败。因此,样品被进一步收集并送到Genoxor医疗科技有限公司(上海,中国)进行下一代测序(NGS)。令人惊讶的是,确定了ClevelandensisLawsonella。因此,敏感的抗生素与彻底的清创和引流配合使用,最后随着伤口逐渐闭合,她的病情完全逆转。
结论:自体脂肪移植隆胸的并发症多种多样,其中感染是最常见的。人类中罕见的病原体,例如丁氏劳氏菌感染,在临床实践中很少见。此外,由于其部分耐酸性,很难与非结核分枝杆菌区分,培养困难和脓肿形成。在我们的报告中,如何准确确定丁氏劳氏菌感染的诊断至关重要,NGS被推荐作为鉴定病原体的有用方法,这可能为我们提供一种新的难愈性伤口的工具。
BACKGROUND: Lawsonella clevelandensis is one recently documented anaerobic, which is partially acid-fast. Nevertheless, it is rarely found to be associated with human infections, especially in scope of plastic and cosmetic surgery before our patient who was performed breast augmentation with autologous fat grafting. Breast augmentation is becoming popular, the most common post-surgery complication of which is bacterial infection.
METHODS: A 29-year-old female who was found swelling in her right breast and fever after breast augmentation surgery with autologous fat grafting was administered. Before administration, she had been treated with antibiotics (details unknown) for more than 1 month without any significant improvements. After administration, she was treated with intravenous antibiotic empirically and repeated debridement via Vaccuum Sealing Drainage (VSD). And samples of the necrotic tissues and pus collected in surgery were sent for microbiological testing. However, routine examination failed. Thus samples were further collected and sent to Genoxor Medical & Science Technology Inc. (Shanghai, China) to conduct Next-Generation Sequencing (NGS). Surprisingly Lawsonella clevelandensis was determined. Accordingly, sensitive antibiotic was applied in concert with thorough debridement and drainage and finally her condition was completely reversed with wound closure gradually.
CONCLUSIONS: Complications of breast augmentation with autologous fat graft are various, of which infection is most common. Rare pathogen such as Lawsonella clevelandensis infection in human is rare in clinical practice. Moreover, it is difficult to differentiate from non-tuberculous mycobacterium for its partial acid resistance, difficulty to culture and abscess formation. How to determine diagnosis of Lawsonella clevelandensis infection accurately come to be critical In our report, NGS is recommended as a useful method to identify the pathogen, which may provide us a novel tool for refractory wound.
