Melioidosis is a bacterial infection caused by a Gram-negative bacillus , prevalent in Southeast Asia and Northern Australia. Sri Lanka is situated in the endemic belt of melioidosis. Melioidosis has a wide spectrum of clinical presentations and results in high mortality rates in severe infection. . We report a 54-year-old previously healthy Sri Lankan farmer who presented with septicemia following a cut injury to the right leg while working in a paddy field. Initially, he had mild wound sepsis, and later, his condition deteriorated rapidly. The patient required organ support later for cardiovascular instability, acute liver failure, acute kidney injury, acute respiratory distress syndrome, and coagulopathy. The patient's blood culture was negative on the admission day, and the repeated blood culture taken at the ICU was contaminated with a commensal flora initially and later isolated . Although wound swab culture taken on the first day isolated an organism, it took six days to identify it as . The patient succumbed to severe melioidosis leading to a severe sepsis and multiorgan failure in spite of treatment with meropenem.
This case report highlights the importance of considering melioidosis as a differential diagnosis when a patient comes with risk factors for melioidosis.
类鼻疽是由革兰氏阴性杆菌引起的细菌感染,在东南亚和澳大利亚北部流行。斯里兰卡位于类鼻疽的流行地带。类鼻疽有广泛的临床表现,在严重感染时会导致高死亡率。我们报告一名54岁、既往健康的斯里兰卡农民,他在稻田劳作时右腿割伤后出现败血症。起初,他有轻度伤口脓毒症,后来病情迅速恶化。患者后来因心血管不稳定、急性肝衰竭、急性肾损伤、急性呼吸窘迫综合征和凝血病而需要器官支持。患者入院当天血培养阴性,在重症监护病房重复进行的血培养最初被共生菌群污染,后来分离出病原体。尽管第一天采集的伤口拭子培养分离出一种微生物,但花了六天才将其鉴定为[具体微生物名称未给出]。尽管使用美罗培南治疗,患者仍死于严重的类鼻疽,导致严重败血症和多器官功能衰竭。
本病例报告强调当患者有类鼻疽危险因素就诊时,将类鼻疽作为鉴别诊断的重要性。
