Thiamine Deficiency

硫胺素缺乏症
  • 文章类型: Journal Article
    韦尼克脑病(WE)是由硫胺素(维生素B1)缺乏引起的急性危及生命的神经系统疾病。WE患者通常表现为眼肌麻痹的三联征,步态共济失调,和精神混乱。如果我们没有得到及时的治疗,它会导致严重的并发症,如混乱,昏迷,或死亡。尽管酗酒是WE最常见的原因,非酒精性原因-尽管罕见-确实存在。在这里,我们介绍了一例非酒精性的延髓梗死女性患者,表现为顽固性呕吐.她的临床状态随后发展为包括眼肌麻痹和步态共济失调。根据她的临床表现怀疑对WE的诊断;脑磁共振成像(MRI)和血清硫胺素水平降低的发现证实了这一点。脑部磁共振成像显示在随访期间异常高强度的完全解决,治疗后6个月。
    Wernicke encephalopathy (WE) is an acute life-threatening neurological condition caused by thiamine (vitamin B1) deficiency. Patients with WE often present with a triad of symptoms consisting of ophthalmoplegia, gait ataxia, and mental confusion. If WE is not treated in a timely manner, it can lead to serious complications such as confusion, coma, or death. Although alcohol abuse is the most commonly reported cause of WE, nonalcoholic causes-although rare-do exist. Herein, we present the case of a nonalcoholic woman with medullary infarctions who presented with intractable vomiting. Her clinical state subsequently progressed to include ophthalmoplegia and gait ataxia. A diagnosis of WE was suspected based on her clinical presentation; this was confirmed by brain magnetic resonance imaging (MRI) and the finding of decreased serum thiamine levels. Brain magnetic resonance imaging demonstrated the complete resolution of abnormal hyperintensities during a follow-up visit, 6 months after treatment.

    硫胺素缺乏症,也被称为脚气病,是由饮食中缺乏硫胺素(维生素B1)引起的营养障碍。它可以以两种形式出现:干脚气病,影响神经系统,和湿的脚气病,影响心血管系统。胃肠脚气病是一种影响消化系统并可导致多系统参与的亚型。在美国(US),硫胺素缺乏通常由慢性营养不良继发酒精中毒,被称为Wernicke-Korsakoff综合症.
    一名45岁女性,没有已知的既往病史或酒精使用障碍,在就诊前几个月出现顽固性恶心和呕吐病史,来到急诊科就诊。在摄入过程中,医疗小组发现她患有双侧下肢无力和阴离子间隙代谢性酸中毒。她的住院体检排除了脑膜炎,脑炎,腹膜炎,糖尿病酮症酸中毒,和脑血管意外。硫胺素缺乏是她出现的最可能原因,继发于她长期的呕吐史和口服药物摄入不良。再喂养综合征使她的住院复杂化。补充硫胺素后,患者经历了精神状况和下肢无力的显著改善。医疗团队后来通过家庭物理治疗康复和营养咨询使她出院。
    硫胺素缺乏症在美国并不常见。然而,该病例强调了当患者患有继发于胃肠道疾病的营养不良史并伴有精神状态和神经系统症状改变的症状时,将这种缺陷纳入差异的重要性。
    UNASSIGNED: Thiamine deficiency, also known as beriberi, is a nutritional disorder caused by a lack of thiamine (vitamin B1) in the diet. It can occur in 2 forms: dry beriberi, which affects the nervous system, and wet beriberi, which affects the cardiovascular system. Gastrointestinal beriberi is a subtype that affects the digestive system and can lead to multisystem involvement. In the United States (US), thiamine deficiency often arises from chronic malnutrition secondary to alcoholism, known as Wernicke-Korsakoff Syndrome.
    UNASSIGNED: A 45-year-old female with no known past medical history or alcohol use disorder came to the emergency department with an altered mental status and with a history of intractable nausea and vomiting for several months prior to presentation. During intake, the medical team discovered she had bilateral lower extremity weakness and an anion gap metabolic acidosis. Her inpatient workup ruled out meningitis, encephalitis, peritonitis, diabetic ketoacidosis, and cerebrovascular accident. A thiamine deficiency was the most probable cause of her presentation, secondary to her protracted history of vomiting and poor oral medication intake. Refeeding syndrome complicated her hospitalization. After replenishing thiamine, the patient experienced significant improvement in mental status and lower extremity weakness. The healthcare team later discharged her with home physical therapy rehabilitation and nutritional counseling.
    UNASSIGNED: Thiamine deficiency is not common in the US. However, this case highlights the importance of including this deficiency in the differential when a patient arrives with a history of malnourishment secondary to a gastrointestinal illness with signs of altered mental status and neurological symptoms.

    简介:维生素B1缺乏会导致意识障碍的风险很大,表现从厌食和疲劳到严重的神经和心血管疾病。韦尼克的脑病,由维生素B1缺乏引起的神经系统疾病,表现为眼肌麻痹的三联征,改变了精神状态,和小脑共济失调.然而,这些症状并不总是存在,使诊断复杂化。此外,亚临床维生素B1缺乏可在出现严重并发症之前未被发现.研究表明,未确诊病例的发生率很高,强调早期发现和干预的必要性。病例介绍:我们介绍了一个65岁男性的病例,其中偶然发现了高乳酸血症,导致维生素B1缺乏的诊断。病人,表现为眩晕和呕吐,在他妻子3年前去世后,他一直在吃从便利店买的盒装午餐。眩晕随着休息逐渐好转,但是高乳酸血症的持续存在促使了进一步的调查,显示低维生素B1水平和高丙酮酸水平。饮食调整和补充剂治疗显着改善了他的症状。讨论:在这种情况下,在一名眩晕患者中发现了高乳酸血症,提示无症状的维生素B1缺乏。乳酸升高通常与败血症等疾病有关,但也可能源于被忽视的因素,例如由于食用油炸食品等不良饮食习惯而导致的维生素B1水平低。结论:该病例强调了在原因不明的高乳酸血症患者中考虑维生素B1缺乏的重要性,即使是在高收入国家。早期发现可以防止进展为与Wernicke脑病相关的严重并发症。主动测量高危人群的乳酸水平可能有助于早期诊断和干预。最终改善患者预后。
    Introduction: Vitamin B1 deficiency poses a significant risk of impaired consciousness, with manifestations ranging from anorexia and fatigue to severe neurological and cardiovascular disturbances. Wernicke\'s encephalopathy, a neurological disorder stemming from vitamin B1 deficiency, presents as the triad of ophthalmoplegia, altered mental state, and cerebellar ataxia. However, these symptoms are not consistently present, complicating the diagnosis. In addition, subclinical vitamin B1 deficiency can progress unnoticed until severe complications arise. Studies indicate a high rate of undiagnosed cases, emphasizing the need for early detection and intervention. Case presentation: We present the case of a 65-year-old man in whom hyperlactatemia was incidentally detected, leading to the diagnosis of vitamin B1 deficiency. The patient, presenting with vertigo and vomiting, had been eating boxed lunches bought from convenience stores following the death of his wife 3 years earlier. Vertigo gradually improved with rest, but the persistence of hyperlactatemia prompted further investigation, revealing low vitamin B1 levels and high pyruvate levels. Treatment with dietary adjustments and supplements significantly improved his symptoms. Discussion: In this case, hyperlactatemia was found in a vertigo patient, revealing asymptomatic vitamin B1 deficiency. Elevated lactate is often linked with conditions like sepsis but can also stem from overlooked factors such as low vitamin B1 levels due to poor diet habits like consuming fried foods. Conclusion: This case highlights the importance of considering vitamin B1 deficiency in patients with unexplained hyperlactatemia, even in high-income countries. Early detection can prevent progression to the severe complications associated with Wernicke\'s encephalopathy. Proactive measurement of lactate levels in at-risk populations may facilitate early diagnosis and intervention, ultimately improving patient outcomes.

    韦尼克脑病(WE)是由于硫胺素(维生素B1)缺乏而很少遇到但严重的神经精神疾病。虽然通常与慢性酒精中毒或饮食摄入不足有关,减肥和代谢手术后的WE实例,特别是腹腔镜Roux-en-Y胃旁路术(RYGB),偶尔被记录在案。本案例研究阐明了一名男性患者的状况,在接受RYGB治疗严重肥胖3个月后,表现出精神状态的突然改变,通过立即静脉注射大剂量硫胺素迅速改善。
    Wernicke encephalopathy (WE) is a seldom encountered yet significant neuropsychiatric ailment resulting from a deficiency in thiamine (vitamin B1). While commonly linked with chronic alcoholism or insufficient dietary intake, instances of WE following bariatric and metabolic surgeries, notably laparoscopic Roux-en-Y gastric bypass (RYGB), have been sporadically documented. This case study elucidates the condition of a male patient who, 3 months after undergoing RYGB to address severe obesity, displayed abrupt alterations in mental status, swiftly ameliorated by immediate administration of intravenous high-dose thiamine.

    维生素和矿物质缺乏是减肥手术后普遍存在的营养障碍。虽然它们在旁路等吸收不良手术后更为普遍,它们也发生在限制性手术中,如胃袖。导致这些缺陷发生的机制与营养摄入不足或对多种维生素和多矿物质补充剂的依从性差有关。Wernicke-Korsakoff综合征(WKS)是一种由硫胺素缺乏引起的急性神经系统疾病。这种综合症由两个不同的阶段组成:第一,韦尼克脑病(WE),这种综合症的急性期,其特点是精神错乱的三合会,眼部体征,和共济失调,其次是WKS的慢性期,称为Korsakoff综合征(KS),以存在顺行性健忘症和虚构而闻名。我们旨在报告一例减肥手术后患有WKS的患者。对患者进行回顾性图表回顾,以检索相关临床数据。患者是一名24岁的女学生,BMI为48kg/m2,因病态肥胖接受了袖状胃切除术。在接下来的两个月里,手术后的恢复因恶心等非特异性症状而变得复杂,反复呕吐,食物摄入量显著减少,这导致患者六次去急诊科就诊,最后一次住院,以获得明确诊断。在住院的15天期间,病人出现了眼复视,眼球震颤,旋转性眩晕的抱怨,和步态异常。对头部进行了磁共振成像,但未发现明显变化。经过正式的神经学评估,用肠胃外硫胺素治疗(100毫克,每天三次)在没有事先给药的情况下开始。观察到的临床改善证实了WKS的诊断。减肥手术可能导致硫胺素缺乏,因此,到WKS。在手术前后,必须对营养不良的不良后果进行教育。术前和术后营养缺乏的调查对于预防WKS等并发症至关重要。
    Vitamin and mineral deficiencies are prevalent nutritional disorders following bariatric surgery. Although they are more prevalent after malabsorptive procedures such as bypass, they also occur in restrictive procedures such as gastric sleeve. The mechanisms that lead to the occurrence of these deficits are related to the presence of poor nutritional intake or poor adherence to multivitamins and multimineral supplementation. Wernicke-Korsakoff syndrome (WKS) is an acute neurological disorder resulting from thiamine deficiency. This syndrome is composed of two distinct phases: first, Wernicke Encephalopathy (WE), the acute phase of this syndrome, which is characterized by a triad of mental confusion, ocular signs, and ataxia, followed by the chronic phase of WKS, called Korsakoff\'s syndrome (KS), which is known for the presence of anterograde amnesia and confabulation. We aimed to report a case of a patient with WKS after bariatric surgery. The patient\'s retrospective chart review was performed in order to retrieve the relevant clinical data. The patient was a 24-year-old female student with a BMI of 48 kg/m2 who underwent sleeve gastrectomy surgery for morbid obesity. Over the following 2 months, recovery from surgery was complicated by non-specific symptoms such as nausea, recurrent vomiting, and a significant reduction in food intake, which led the patient to visit the emergency department six times with hospitalization on the last occasion for a definitive diagnosis. During the 15 days of hospitalization, the patient developed ocular diplopia, nystagmus, complaints of rotatory vertigo, and gait abnormalities. A magnetic resonance imaging of the head was performed but revealed no significant changes. After a formal neurological assessment, treatment with parenteral thiamine (100 mg, three times a day) was started without prior dosing. The observed clinical improvement confirmed the diagnosis of WKS. Bariatric surgery may contribute to thiamine deficiency and, consequently, to WKS. Education about the adverse consequences of malnourishment is mandatory before and after the surgery. Investigation of nutritional deficiencies both pre- and post-operatively is crucial in order to prevent complications such as WKS.

    酒精一直是人类文明饮食模式中的一个组成部分。它在社会中广泛用于庆祝和社会化。酒精滥用是公共卫生中最严重的问题之一,其特征是不受控制的饮酒会导致身体和情感上对酒精的依赖。慢性酗酒者由于吸收不良而出现维生素B1缺乏症的风险较高,不良饮食,以及对营养需求的增加。维生素B1(硫胺素)是人体能量代谢和神经系统正常运作所需的必需营养素。过度消耗madya(酒精)然后突然停止饮酒并再次饮用过量madya的人,患有MadatyayaUpadrava(慢性酒精中毒),即Vikshay。这是一例酒精患者停止饮酒,然后大量恢复饮酒的病例报告。他表现出全身无力的症状,身体疼痛,失语症,混乱,发烧(开和关),口渴,咳嗽,头痛,和麻木。该患者接受了为期两个月的治疗方案,该方案结合了SatvavajayChikitsa,瑜伽,和ShamanChikitsa涉及Rasayana药物和程序,包括snehan(油),Swedan(fomentation),nabhipuran(用肚脐填充油),Nasya(鼻腔给药),shirodhara(液体在头上连续流动)和basti(药物灌肠)。干预结果显示上述症状缓解,症状和GCS(格拉斯哥昏迷量表)评分均得到改善。这种治疗方法旨在促进活力,长寿,以及整体的平衡感和幸福感。阿育吠陀报告和管理的佐证案件并不多。本病例报告强调了通过Rasayana药物的累积效应来改变健康,Panchakarma,还有瑜伽.
    Alcohol has always been a component in the dietary pattern of human civilization. It is widely used in society for celebration and socialization. Alcohol abuse is among the most serious problems in public health characterized by uncontrolled drinking which causes physical and emotional dependence on alcohol. Chronic alcoholics are at a higher risk of developing vitamin B1 deficiency due to malabsorption, poor diet, and an increased demand for nutrition. Vitamin B1(Thiamine) is an essential nutrient required for the body\'s energy metabolism and proper functioning of the nervous system. A person who excessively consumes madya (alcohol) and then abruptly discontinues drinking and takes recourse to drinking excess madya once again, suffers from Madatyaya Upadrava(chronic alcoholism) that is Vikshay. Here is a case report of an alcoholic patient who ceased drinking and then resumed alcohol in large amounts. He presented with symptoms of generalized weakness, body ache, aphasia, confusion, fever (on and off), thirst, cough, headache, and numbness. The patient underwent a two-month treatment regimen that combined Satvavajay Chikitsa, Yoga, and Shaman Chikitsa involving Rasayana medications and procedures including snehan (Oleation), swedan (fomentation), nabhi puran (filling oil with navel), nasya (nasal administration), shirodhara (continuous flow of liquid on head) and basti (medicated enema). The intervention outcome showed relief from the aforementioned symptoms and improvement in both symptoms and GCS(Glasgow coma scale) score. This treatment approach aimed to promote vitality, longevity, and an overall sense of balance and well-being. There are not many corroborating cases being reported and managed with Ayurveda. This case report highlights transforming health through the cumulative effects of Rasayana medicines, panchakarma, and yoga.

    硫胺素(维生素B1)是一种必需营养素,也是八种B族维生素之一。作为一种水溶性维生素,硫胺素不储存;因此,需要均衡的饮食来确保这种必需维生素的充足摄入。已知硫胺素缺乏会导致干湿脚气病,但很少结合。硫胺素缺乏也已知会导致QTc延长,但机制尚不清楚。在最严重的情况下,这可能导致尖端扭转性心律失常。该病例描述了一名患者,该患者在闭合性颅脑损伤后营养不良,最初表现为癫痫样活动和晕厥发作,伴有非特异性麻木。他被发现延长了QTc,导致尖端扭转,需要植入心脏复律除颤器。通过广泛的检查,包括基因检测,患者被发现检测不到硫胺素水平。随着补充,患者不再有任何室性心律失常的记录,和神经功能改善,只有残余的刺痛在手中。此案例强调了硫胺素缺乏症的深远影响,以及为什么应将其纳入我们对出现所讨论体征和症状后遗症的患者的鉴别诊断中。
    Thiamine (vitamin B1) is an essential nutrient and one of the eight B vitamins. As a water-soluble vitamin, thiamine is not stored; therefore, a balanced diet is required to ensure adequate intake of this essential vitamin. Thiamine deficiency is known to cause both wet and dry beriberi, but rarely in combination. Thiamine deficiency has also been known to cause QTc prolongation, but the mechanism remains unclear. In the most severe cases, this can lead to the lethal arrhythmia of torsades de pointes. This case describes a patient who became malnourished after a closed head injury and initially presented with seizure-like activity and syncopal episodes with nonspecific numbness. He was found to have prolonged QTc, leading to torsades de pointes requiring an implanted cardioverter defibrillator. With extensive workup, including genetic testing, the patient was found to have indetectable thiamine levels. With supplementation, the patient no longer had any recorded ventricular arrhythmias, and neurological function improved with only residual tingling in the hands. This case emphasizes the profound effects of thiamine deficiency and why this should be included in our differential diagnosis for patients presenting with the sequelae of the signs and symptoms discussed.

    乳酸性酸中毒的特征在于乳酸的过量产生或其清除率受损。硫胺素缺乏是乳酸性酸中毒的罕见原因,特别是在营养不良很少的国家。我们描述了一个5岁男孩的病例,该男孩表现为急性淋巴细胞白血病的中枢神经系统复发。化疗期间,患者出现药物性胰腺炎伴麻痹性肠梗阻,需要长期输注葡萄糖盐水溶液.在接下来的日子里,重度乳酸性酸中毒(pH7.0,乳酸253mg/dL,检测到HCO3-8mmol/L),与低血糖(42mg/dL)和急性肝损伤的实验室体征相关。由于持续的低血糖,葡萄糖输注逐渐增加.乳酸盐,然而,继续提高,所以开始了持续的静脉血液透析滤过。虽然乳酸盐最初减少,CVVHDF暂停后12小时,他们又开始提高。假设它可能是由长期禁食和进食困难后维生素缺乏引起的线粒体功能障碍引起的,给予胃肠外营养和硫胺素,导致乳酸盐的逐渐减少,在接下来的几个小时内pH值正常化。在长期住院患者出现急性和进行性乳酸性酸中毒的情况下,硫胺素缺乏症应仔细考虑并尽早治疗.
    Lactic acidosis is characterized by an excessive production of lactic acid or by its impaired clearance. Thiamine deficiency is an uncommon cause of lactic acidosis, especially in countries where malnutrition is rare. We describe the case of a 5-year-old boy who presented with a central nervous system relapse of acute lymphoblastic leukemia. During the chemotherapy regimen, the patient developed drug-induced pancreatitis with paralytic ileus requiring prolonged glucosaline solution infusion. In the following days, severe lactic acidosis (pH 7.0, lactates 253 mg/dL, HCO3- 8 mmol/L) was detected, associated with hypoglycemia (42 mg/dL) and laboratory signs of acute liver injury. Due to the persistent hypoglycemia, the dextrose infusion was gradually increased. Lactates, however, continued to raise, so continuous venovenous hemodiafiltration was started. While lactates initially decreased, 12 h after CVVHDF suspension, they started to raise again. Assuming that it could have been caused by mitochondrial dysfunction due to vitamin deficiency after prolonged fasting and feeding difficulties, parenteral nutrition and thiamine were administered, resulting in a progressive reduction in lactates, with the normalization of pH during the next few hours. In the presence of acute and progressive lactic acidosis in a long-term hospitalized patient, thiamine deficiency should be carefully considered and managed as early as possible.
