Hemolysis can occur in people with G6PD deficiency under oxidative stress. Acalypha indica is a tropical plant used as a medicinal plant as well as a vegetable. There are a few reported cases of Acalypha indica ingestion induced hemolysis in G6PD deficient people. All except one of them are from Sri Lanka. The information available at present (2017) about G6PD deficiency prevalence and variants of the G6PD gene among Sri Lankans is very sparse. There are no past reports on hemolytic crisis in a G6PD deficient person presenting mimicking leptospirosis.
A middle-aged Sri Lankan man presented on the third day of illness complaining of fever, head ache, arthralgia, myalgia, abdominal pain, vomiting, passing dark urine and reduced of urine volume. He gave a history of possible exposure to leptospirosis. He was pale, icteric and his liver was palpable 1 cm below costal margin and there were no other remarkable findings upon physical examination. He had neutrophilic leucocytosis. Leptospirosis was diagnosed. During the second assessment we noticed he was very pale and his urine sample pointed towards hemoglobinuria. Further questioning revealed he had consumed leaves of Acalypha indica as a vegetable. Acute hemolysis in a G6PD deficient patient following Acalypha indica ingestion was diagnosed. Blood transfusions were given to correct his anemia. Later, Brewer's test and quantitative assay of G6PD levels confirmed the diagnosis of G6PD deficiency.
A hemolytic crisis following oxidative stresses in G6PD deficient patients can present mimicking leptospirosis. Further investigations may reveal why the great majority of cases of acute hemolysis in G6PD deficient person following Acalypha indica ingestion are from Sri Lanka.
葡萄糖-6-磷酸脱氢酶(G6PD)缺乏症患者在氧化应激状态下可能发生溶血。印度铁苋菜是一种热带植物,既是药用植物也是蔬菜。有几例关于印度铁苋菜摄入导致G6PD缺乏症患者溶血的报道。除1例之外,其余均来自斯里兰卡。目前(2017年)关于斯里兰卡人G6PD缺乏症患病率及G6PD基因变异的信息非常稀少。既往没有关于G6PD缺乏症患者出现类似钩端螺旋体病的溶血危象的报道。
一名中年斯里兰卡男性在患病第3天就诊,主诉发热、头痛、关节痛、肌痛、腹痛、呕吐、排深色尿及尿量减少。他有可能接触钩端螺旋体病的病史。他面色苍白、黄疸,肝脏在肋缘下1厘米可触及,体格检查无其他明显异常。他有中性粒细胞增多性白细胞增多症。诊断为钩端螺旋体病。在第二次评估时,我们注意到他面色极度苍白,尿液样本提示血红蛋白尿。进一步询问发现他食用了印度铁苋菜的叶子作为蔬菜。诊断为G6PD缺乏症患者摄入印度铁苋菜后发生急性溶血。给予输血以纠正贫血。后来,布鲁尔试验及G6PD水平定量测定证实了G6PD缺乏症的诊断。
G6PD缺乏症患者在氧化应激后发生的溶血危象可能表现类似钩端螺旋体病。进一步的研究可能会揭示为什么G6PD缺乏症患者摄入印度铁苋菜后发生急性溶血的绝大多数病例来自斯里兰卡。
