Abstract

Buruli ulcer, caused by Mycobacterium ulcerans, is increasing in incidence and spreading to new areas in southeast Australia. With increasing experience and emerging evidence, this consensus statement considers contemporary data to provide up-to-date recommendations to clinicians who may encounter this disease. The emergence of Buruli ulcer in previously non-endemic areas highlights the importance of increasing clinician and community awareness of this disease. Main recommendations and changes in management as a result of this consensus statement: Buruli ulcer is a notifiable disease in Victoria, the Northern Territory and Queensland. Cases identified in other states or territories should be discussed with relevant health authorities. We call for Buruli ulcer to be made nationally notifiable to monitor for its potential emergence in non-endemic regions. Diagnosis using polymerase chain reaction is sensitive and specific if performed correctly; a dry swab under the undermined edge of ulcers or a tissue sample via punch biopsy if the lesion is not ulcerated is recommended. If swabs are incorrectly performed or performed on non-ulcerated skin, they can give a false negative result. There is high quality evidence to support treatment of eight weeks' duration using rifampicin-based dual oral antibiotic therapy, in combination with clarithromycin or a fluoroquinolone; relapse is very rare but can occur in people with risk factors. There is emerging evidence for shorter durations of treatment (six weeks) in individuals with small lesions who are at low risk of relapse and in those who have undergone surgical excision of the lesion (four weeks). Patients should be warned that ulcers typically enlarge with antibiotic treatment, will not have healed by completion of antibiotics, and take a median of four to five months to heal. Surgical management is usually not required, but may be beneficial to reduce healing times, avoid or reduce the duration of antibiotics, and manage paradoxical reactions. Early identification and treatment of paradoxical reactions is important, as they are associated with increased tissue necrosis and delayed wound healing. Good wound care is critical in successful treatment of Buruli ulcer, as it enhances healing and prevents secondary bacterial infection. Compared with adults, children have a higher proportion of non-ulcerative and severe lesions, are less likely to experience adverse antibiotic effects, but have higher rates of paradoxical reactions; specialist referral is recommended.

摘要

由溃疡分枝杆菌引起的布鲁里溃疡发病率正在上升,并蔓延至澳大利亚东南部的新地区。随着经验的增加和新证据的出现,本共识声明参考当代数据,为可能遇到这种疾病的临床医生提供最新建议。布鲁里溃疡在以前的非流行地区出现,凸显了提高临床医生和社区对这种疾病认识的重要性。本共识声明带来的主要建议和管理变化:在维多利亚州、北领地和昆士兰州,布鲁里溃疡是一种须上报的疾病。在其他州或领地发现的病例应与相关卫生当局进行讨论。我们呼吁将布鲁里溃疡列为全国须上报疾病,以监测其在非流行地区可能的出现情况。如果操作正确,使用聚合酶链反应进行诊断既敏感又特异;对于溃疡,建议在溃疡边缘下方取干燥拭子;如果病变未溃疡,则通过打孔活检获取组织样本。如果拭子操作不当或在非溃疡皮肤上操作,可能会得出假阴性结果。有高质量证据支持使用基于利福平的双联口服抗生素疗法进行为期八周的治疗,并联合克拉霉素或氟喹诺酮;复发非常罕见,但有危险因素的人可能会复发。有新证据表明,对于复发风险低的小病灶患者以及已接受病变手术切除的患者(四周),治疗时间可缩短(六周)。应告知患者,溃疡通常会随着抗生素治疗而扩大,抗生素疗程结束时不会愈合,平均需要四到五个月才能愈合。通常不需要手术治疗,但手术可能有助于缩短愈合时间、避免或减少抗生素使用时间,并处理矛盾反应。早期识别和治疗矛盾反应很重要,因为它们与组织坏死增加和伤口愈合延迟有关。良好的伤口护理对于成功治疗布鲁里溃疡至关重要,因为它可促进愈合并防止继发细菌感染。与成人相比,儿童的非溃疡性和严重病变比例更高,不太可能出现抗生素不良反应,但矛盾反应发生率更高;建议转诊至专科医生处。
