ABSTRACT

Resumo O beribéri é a manifestação clínica da deficiência grave e prolongada de tiamina (vitamina B1). Doença negligenciada que acomete a população de baixa renda, em situação de insegurança alimentar e nutricional. O objetivo do estudo foi comparar casos de beribéri em indígenas com casos em não indígenas no Brasil. Trata-se de estudo transversal de casos notificados de beribéri no período de 2013 a 2018, no formulário do SUS (FormSUS) do Ministério da Saúde. Foram comparados os casos em indígenas e em não indígenas pelo teste qui-quadrado ou teste exato de Fisher com nível de significância de p < 0,05. No período estudado foram notificados no país 414 casos de beribéri, sendo 210 (50,7%) indígenas. Referiram consumo de bebidas alcoólicas 58,1% dos indígenas e 71,6% dos não-indígenas (p = 0,004); adicionalmente, 71,0% dos indígenas consumiam caxiri (bebida alcoólica tradicional fermentada). Relataram fazer esforço físico diário 76,1% dos indígenas e 40,2% dos não-indígenas (p <0 ,001). Conclui-se que o beribéri no país acomete mais indígenas e está relacionado ao consumo de álcool e ao esforço físico.


Abstract Beriberi is the clinical manifestation of severe and prolonged thiamine (vitamin B1) deficiency. It is a neglected disease that affects low-income populations facing food and nutrition insecurity. The aim of this study was to compare cases of beriberi among indigenous and non-indigenous people in Brazil. We conducted a cross-sectional study using data on cases of beriberi during the period July 2013-September 2018 derived from beriberi notification forms available on the FormSUS platform. Cases in indigenous and non-indigenous patients were compared using the chi-squared test or Fisher's exact test, adopting a significance level of 0.05. A total of 414 cases of beriberi were reported in the country during the study period, 210 of which (50.7%) were among indigenous people. Alcohol consumption was reported by 58.1% of the indigenous patients and 71.6% of the non-indigenous patients (p = 0.004); 71.0% of the indigenous patients reported that they consumed caxiri, a traditional alcoholic drink. Daily physical exertion was reported by 76.1% of the indigenous patients and 40.2% of the non-indigenous patients (p < 0.001). It is concluded that beriberi disproportionately affects indigenous people and is associated with alcohol consumption and physical exertion.

ABSTRACT

Abstract Objective: In this study, we created an animal model to demonstrate the effects of thiamine on the hearing pathways of new-borns during pregnancy and lactation by inducing a dietary thiamine deficiency in the mother. Methods: The study included 16 female Wistar albino rats. The animals were separated into four groups and provided the appropriate amounts of dietary thiamine according to their groups during pre-pregnancy, pregnancy, and lactation periods. Three pups from each mother were included in the study, and 12 pups were selected from each group. On the fortieth day after birth, the auditory pathways of 48 pups in the 4 groups were examined electro physiologically and ultra-structurally. Results: In Group N-N, morphology of hair cells stereocilia degeneration was not obtained in all turns of cochlea. In Group N-T, Inner Hair Cells (IHCs) and Outher Hair Cells (OHCs) stereocilia didn't show degeneration in all turns of cochlea but had rupture inrows of HCs stereocilia. In group T-N IHCs stereocilia less degeneration was observed in all turns of cochlea. OHC stereocilia partial loss was observed only in basal turn of cochlea. In Group T-T IHCs stereocilia was observed less degeneration and rupture in all turns of cochlea. Conclusion: Thiamine is vital for the development of cochlear hair cells during both prenatal and postnatal periods. Even partial deficiency of thiamine causes significant degeneration to the auditory pathway. Level of evidence: The level of evidence of this article is 5. This article is an experimental animal and laboratory study.

ABSTRACT

Biotin-thiamine-responsive basal ganglia disease is a rare treatable autosomal recessive neurometabolic disorder caused by mutations in SLC19A3 gene, encoding a transporter of thiamine across the plasma membrane. In the present study, a 29-year-old male patient with epilepsy as the first symptom, accompanied by hypokinesia, extraocular muscle paralysis and delayed dystonia was reported. The brain magnetic resonance imaging revealed abnormal symmetrical signals of bilateral caudate nucleus and lenticular nucleus. The patient was diagnosed as biotin-thiamine-responsive basal ganglia disease by gene detection. After treatment with biotin and thiamine, the symptoms were relieved and the brain lesions subsided.

ABSTRACT

Objective:To analyze the abnormal vestibular function of Wernicke encephalopathy (WE) and to explore its diagnostic value.Methods:WE patients who visited the Vertigo Center of the Second Affiliated Hospital of Zhengzhou University from January 2018 to January 2021 were retrospectively collected. All patients were evaluated by clinical neurology. Before treatment, all patients completed video head impulse test (vHIT) and video nystagmusgraphy (VNG) in addition to cranial magnetic resonance and serum thiamine level examination.Results:All 12 patients had a history of eating defects, including 8 cases of alcoholism. All 12 patients had walking instability, 7 cases had dizziness and 8 cases had oscillopsia. Six cases had ophthalmoplegia. All 12 cases showed positive gaze nystagmus. The pathological saccades of bilateral horizontal semicircular canals were found in 12 patients by vHIT before treatment, but there was only 1 patient showing abnormality in vertical semicircular canals, the difference being statistically significant ( P<0.05). All patients could detect bilateral, horizontal, gaze-evoked nystagmus, including 3 cases with vertical nystagmus, 1 case with abnormal saccade test, 3 cases with abnormal smooth tracking test and 1 case with abnormal optokinetic test. There were abnormalities in the caloric test, including 6 cases of bilateral dysfunction and 2 cases of unilateral dysfunction. Conclusions:WE patients may have abnormal vHIT and bilateral, horizontal, gaze-evoked nystagmus, which is similar to the special abnormal signs of simultaneous damage of both peripheral and central vestibular dysfunction.Vestibular function test is valuable for diagnosis of WE, and it is suitable for patients with a history of nutritional disorders who have dizziness or walking instability and suspected WE.

ABSTRACT

ABSTRACT The Paraguayan War ended 150 years ago. Back then, there were outbreaks of combatants' limb weakness and tingling related to "palustrian cachexia", not clearly funded at the time on nutritional deficiency, the use of native flora to feed troops, and alcoholism. We report a case of a soldier with ascending paralysis, mental confusion and finally tetraplegia with preserved oculomotricity. This would probably be a case of locked-in syndrome (LIS) due to Gayet-Wernicke's encephalopathy consequent to thiamine deficiency. The role of thiamine in the peripheral or central nervous system expression was shown decades later to be related to poor diet, or use of foods containing thiaminase or thiamine antagonists, worsened by the fact that the bodily stores of thiamine are restricted, and deficits may grow fast.


RESUMO A Guerra do Paraguai terminou há 150 anos. Houve surtos de fraqueza dos membros dos combatentes e parestesias relacionadas à "caquexia palustre", não claramente fundamentados na época sobre deficiência nutricional, o uso da flora nativa para alimentar as tropas e o alcoolismo. Referimo-nos a um caso de um militar com paralisia ascendente, confusão mental e finalmente tetraplegia com oculomotricidade preservada. Esse relato seria provavelmente devido a um caso de "síndrome do encarceramento" secundário à encefalopatia de Gayet-Wernicke consequente à deficiência de tiamina. O papel da tiamina na expressão periférica ou do SNC foi previsto décadas mais tarde em relação a uma dieta pobre, ou ao uso de alimentos contendo tiamina ou antagonistas da tiamina, agravado pelo fato de que as reservas corporais de tiamina são restritas, e os déficits podem se manifestar rapidamente.

ABSTRACT

A síndrome de Wernicke-Korsakoff é uma rara encefalopatia desencadeada pela deficiência de tiamina, uma vitamina do complexo B, que atua como importante cofator de enzimas responsáveis pela manutenção da homeostase da energia cerebral. Apresentamos o caso de uma paciente de 18 anos, gestante, com diagnóstico prévio de pancreatite aguda biliar, que evoluiu à hiperêmese gravídica e à Wernicke-Korsakoff. Objetivamos, com este trabalho, chamar a atenção para a importância do diagnóstico imediato dessa síndrome diante de seu potencial em causar danos cerebrais irreversíveis, caso não tratada precocemente.


Wernicke-Korsakoff syndrome is a rare encephalopathy triggered by deficiency of thiamine, a B-complex vitamin, which acts as an important cofactor of enzymes responsible for maintaining brain energy homeostasis. We present the case of an 18-year-old pregnant woman with previous diagnosis of acute biliary pancreatitis, who developed hyperemesis gravidarum and Wernicke-Korsakoff. With this work, we aim to draw attention to the importance of the immediate diagnosis of this syndrome in view of its potential to cause irreversible brain damage if not treated early.

ABSTRACT

Abstract Wernicke encephalopathy (WE) is an acute neurological disorder resulting from vitamin B1 deficiency, which is common in chronic alcoholism. We report a rare case of WE due to hyperemesis gravidarum in a 25-year-old pregnant patient at 13 weeks and 5 days of gestation. Initially, the disease manifested as weakness, mental confusion, anterograde amnesia, and visual and auditory hallucinations. The diagnosis was established after the detection of suggestive findings of WE in the thalamus by magnetic resonance imaging (MRI) and a rapid improvement in the patient's clinical status subsequent to treatment with thiamine. Hyperemesis is a rare cause of WE, which makes the reported case important in the literature and reinforces the need for attention in clinical practice to rare but important complications of this common condition (hyperemesis gravidarum).


Resumo A encefalopatia de Wernicke (EW) é uma condição neurológica aguda resultada da deficiência de vitamina B1, muito comum em etilistas crônicos. Relatamos um caso de EW secundário a um quadro de hiperêmese gravídica em uma gestante de 25 anos de idade e 13 semanas e 5 dias de idade gestacional. Inicialmente essa desordem se manifestou como fraqueza, confusão mental, amnésia anterógrada, e alucinações auditivas e visuais. O diagnóstico foi estabelecido depois da detecção de achados sugestivos de EW na ressonância nuclear magnética e da melhora do quadro clínico com reposição de tiamina. A hiperêmese gravídica não é uma causa comum de EW, o que faz com que o presente relato de caso tenha importância na literatura e reforça a necessidade de atenção na prática clínica para complicações raras mas importantes desse quadro tão comum (hiperêmese gravídica).

ABSTRACT

Objective: Pregnancy a normal physiological condition is worsened by morning sickness, nausea and vomiting of pregnancy, hyperemesis gravidarum, Wernicke’s encephalopathy and Korsakoff syndrome in vulnerable women with gestation. This report of three cases described hyperemesis gravidarum, Wernicke’s encephalopathy and Korsakoff syndrome in the worsening pregnancies.Methods:Prospective collection of data concerning three pregnant patients seen in Dubai Health Care City, Dubai, United Arab Emirates. Results:All three patients were admitted to the hospital with manifestations of HG and WE and one of them showed additional features of Korsakoff syndrome. One patient developed intractable hyponatremia and central pontine myelinolysis. Two patients developed abortion while one patient's pregnancy ended with successful delivery with living infant. All patients were managed with thiamine, antiemetics, parenteral fluids and electrolytes and one patients required steroid therapy. Conclusion:The findings of these cases are compatible with international literature on HG and its sequential syndromes. This study may enhance awareness of HG, WE and KS and also fill the knowledge gap of professionals providing services to women with worsening health during pregnancy in Arabian Gulf countries

ABSTRACT

Background: Beri Beri is still seen in Asian countries due to the large-scale consumption of thiamine depleted polished rice. Thiamine deficiency related disorders are increasingly being reported from Kashmir from last two decades. Specifically, a sensorimotor axonal neuropathy occasionally develops from thiamine deficiency and may occur even without associated Wernicke’s encephalopathy.Methods: This study is a retrospective observational study. All peripartum females referred to our departments from January 2016 to December 2017 with complaints of generalized weakness and or sensory symptoms in form of paresthesias /numbness in limbs were enrolled. Clinical features, electrophysiological features, course in hospital and response to treatment in suspected thiamine deficiency related neuropathy patients were recorded.Results: Forty-three cases were included in the study. Twenty-nine patients were suspected to have nutritional neuropathy because of thiamine deficiency at the time of admission. Out of these 27 showed improvement on treatment with thiamine.Conclusions: Thiamine responsive neuropathy is common in peripartum women of this part of world. Diagnosis is usually made clinically, in at risk individuals presenting with characteristic clinical features.

ABSTRACT

Background: Gastrointestinal manifestations of thiamine deficiency have not been well described in literature. Authors aimed to study the symptoms of gastrointestinal beriberi in a cohort of patients of non-alcoholic Wernicke’s encephalopathy and review the relevant literature.Methods: In a retrospective analysis, case records of 52 patients diagnosed with non-alcoholic Wernicke’s encephalopathy were analyzed for the nature of gastrointestinal symptoms, their duration, severity and associated findings, investigations and response to treatment. The available literature on gastrointestinal symptoms in thiamine deficiency disorders and gastrointestinal beriberi was reviewed.Results: Gastrointestinal symptoms were found in 46 of the 52 patients. The most common gastrointestinal symptom in our patients was recurrent vomiting in 42 patients. Eight patients had water brash. Ten patients had epigastric pain and 10 patients had anorexia. Based on the nature and severity of symptoms, patients were evaluated for their symptoms using endoscopy, ultrasonography, amylase and lactate levels, and routine laboratory studies and the results were normal in the majority of patients.  Gastrointestinal symptoms settled in all the patients after receiving intravenous thiamine. On reviewing the literature multiple studies were found to have reported prominent gastrointestinal symptoms in patients of Wernickes encephalopathy and other thiamine deficiency related disorders. However, the definition of gastrointestinal beriberi is not clearly stated.Conclusions: Gastrointestinal symptoms were prominent prodromal manifestations in our cohort of Wernicke’s encephalopathy and have also been amply reported in literature. Presence of gastrointestinal symptoms in individuals predisposed to thiamine deficiency without alternative explanation should be enough to label a patient as gastrointestinal beriberi. The study highlights the importance of recognizing gastrointestinal beriberi as a distinct syndrome that may precede the development of Wernicke’s encephalopathy.

ABSTRACT

Background: Following the invention of monaural stethoscope by Laennec and X ray by Roentgen in 18th century there was spectacular advancements in cardiology. The myocardium can be affected by various disease process unrelated to abnormal pressure or volume loads. These processes may be inflammatory, metabolic, infiltrative, ischemic or primary with significant overlap. These diseases usually present as cardiomegaly. In pediatric age group cardiac diseases will present early, sometimes without any signs and symptoms like sudden death due to less cardiac reserve. Few cases of sudden death also showed huge cardiomegaly in postmortem X rays. authors want to carry out this study to find out most common cause of cardiomegaly with silent chest as authors usually miss the diagnosis and these cases may present as sudden death without giving much time to intervene. The aim of the study is to know the most common cause of cardiomegaly without significant murmur in pediatric age group above one year.Methods: Prospective observational study done at a tertiary care hospital Hyderabad over a period of one year from January 2018 to January2019.Results: Most common cause of cardiomegaly without significant murmur was cardiac beriberi. It is mostly prevalent in rural areas of Telangana, mostly occurring in breastfed babies and below six years. All cases were recovered after proper treatment. Fortunately, it is associated with nil mortality, if timely treatment was initiated.Conclusions: Cardiac beriberi which is easily preventable and if treated in proper time it will associated with nil mortality. As it was occurring commonly breastfed babies supplementation of Thiamine to mothers was very useful as a preventive strategy.

ABSTRACT

Thiamine (vitamin B₁) is a water-soluble vitamin that is not endogenously synthesized in humans. It is absorbed by the small intestine, where it is activated. Its active form acts as a coenzyme in many energy pathways. We report a rare case of thiamine deficiency in a 3.5-year old boy with short bowel syndrome secondary to extensive bowel resection due to necrotizing enterocolitis during his neonatal age. The patient was parenteral nutrition-dependent since birth and had suffered from recurrent central catheter-related bloodstream infections. He developed confusion with disorientation and unsteady gait as well as profound strabismus due to bilateral paresis of the abductor muscle. Based on these and a very low thiamine level he was diagnosed and treated for Wernicke encephalopathy due to incomplete thiamine acquisition despite adequate administration. He fully recovered after thiamine administration. After 1999 eight more cases have been reported in the PubMed mostly of iatrogenic origin.

ABSTRACT

OBJECTIVE@#This study aimed to evaluate the influence of oral supplementation with benfotiamine on oxidative stress in the liver, heart and muscles of endurance-trained mice.@*METHODS@#Twenty-five male BALB/c mice were allocated to the following treatment groups: standard diet and sedentary activity (Sta-Sed), benfotiamine-supplemented diet and sedentary activity (Ben-Sed), standard diet and training activity (Sta-Tr) and benfotiamine-supplemented diet and training activity (Ben-Tr). The training comprised 6 weeks of endurance swimming training. The concentration of thiobarbituric acid reactive substances (TBARS), carbonylated proteins, total thiols and non-protein thiols was analyzed in the liver, heart and tibialis anterior muscle.@*RESULTS@#In the muscle, TBARS concentration in the Sta-Sed group was higher than that in other groups; in the heart, TBARS concentration in the Sta-Sed and Ben-Tr groups was higher than that in the Ben-Sed group. The carbonyl content of the muscle tissues was higher in the Sta-Sed group than in both supplemented groups. In liver, the carbonyl content was lower in the Ben-Sed group than in the Sta-Sed group. The level of total thiols was lower in the Ben-Sed group than in the Sta-Tr group. In the heart, the level of total thiols was higher in the Ben-Sed group than in the Ben-Tr group. The concentration of non-protein thiols in the muscle was higher in the Ben-Sed group than in the Ben-Tr group, whereas in the heart, concentration of non-protein thiols of Sta-Tr group was lower than that of Sta-Sed group.@*CONCLUSION@#The results show that benfotiamine is an efficient antioxidant for the anterior tibialis muscle and heart; however, swimming training did not alter redox status.

ABSTRACT

Wernicke encephalopathy is a syndrome caused by thiamine deficiency whose three typical symptoms are ophthalomoplegia, ataxia, and confusion. There are also rare reports of bilateral hearing loss, which can be caused by damage to the bilateral inferior colliculus or thalamic lesions, or by energy failure of the cochlea. This case suggests that thiamine should be administered based on the possibility of Wernicke encephalopathy occurring in malnourished or alcoholic patients with sudden bilateral hearing loss.

ABSTRACT

SUMMARY Wernick's Encephalopathy (WE) is an acute neuropsychiatric syndrome caused by thiamine deficiency post hematopoietic stem cell transplant (HSCT). WE is associated with high mortality and morbidity rates, but due to its rare occurrence, it is rarely considered in patients submitted to this procedure. Considering that, the manuscript reports the clinical characteristics and the possible factors that predisposed the occurrence of WE in a patient with non-Hodgkin's lymphoma post-Autologous HSCT. We conclude that WE should be considered in patients submitted to autologous HSCT associated with prolonged use of TPN and malnutrition.

ABSTRACT

RESUMEN Introducción: La hiperémesis gravídica (HG) es una condición frecuente en el embarazo, que puede resultar en complicaciones potencialmente letales como la encefalopatía de Wernicke (EW), síndrome que al ser reconocido y tratado tardíamente puede traducirse en una alta morbi-mortalidad materna y fetal. Objetivo: Describir el primer caso de EW secundario a HG en Colombia y realizar una revisión de la literatura publicada sobre su diagnóstico y tratamiento. Materiales y métodos: Se describe un caso de EW secundario a HG en el que se brindó un manejo interdisciplinario. Se realizó una revisión de la literatura con los términos "encefalopatía de Wernicke", "hiperémesis gravídica" y "embarazo" incluyendo reportes de casos, series de casos, artículos de revisión, investigaciones originales o cartas al editor en inglés, español y francés, en donde se analizaron el método y tiempo del diagnóstico, pauta de tratamiento y estado funcional final. Resultados: Se incluyeron 69 publicaciones y se identificaron 89 casos. En 23 de ellos se presentó pérdida gestacional, sólo en el 12,4% de los casos se reportó el nivel de tiamina, de los cuales en el 90% se encontraba disminuido y de los casos en donde se reportó estado funcional final en el 5,9% la gestante falleció. Conclusión: La EW secundaria a HG es una complicación potencialmente letal. Debe sospecharse ante cualquier alteración neurológica e historia de emesis persistente. El diagnóstico y tratamiento oportuno interdisciplinario son fundamentales para disminuir el riesgo de secuelas que limitan la capacidad funcional con alto impacto en la calidad de vida.


ABSTRACT Introduction: Hyperemesis gravidarum (HG) is a frequent condition in pregnancy, which can result in potentially lethal complications such as Wernicke encephalopathy (WE), a syndrome that can be translated into a high maternal and fetal morbidity and mortality if it is recognized and treated late. Objective: To describe the first case of WE due to HG in Colombia and to review the published literature about its diagnosis and treatment. Materials and methods: We describe a case of WE due to HG with an interdisciplinary approach. A review of the literature was performed with the terms "Wernicke's encephalopathy", "hyperemesis gravidarum" and "pregnancy" including case reports, case series, review articles, original investigations or letters to the editor in English, Spanish and French, where the method and time of the diagnosis, treatment regimen and sequelae were analyzed. Results: Sixty-nine publications were included and 89 cases were identified. In 23 of them had a gestational loss, only in 12.4% of the cases the thiamine level was reported, in which 90% was diminished and in the cases where the final functional status was reported in 5.9% of the pregnant woman died. Conclusion: WE due to HG is a potentially lethal complication. In any neurological disturbance and history of persistent emesis it should be suspected. Timely interdisciplinary diagnosis and treatment are essential to reduce the risk of sequelae that limit functional capacity with a high impact on quality of life.

ABSTRACT

Wernicke’s encephalopathy (WE) is an acute neuropsychiatric condition that occurs due to reversiblebiochemical lesions caused by depletion of intracellular Thiamine (Vitamin B1). WE is characterized bythe triad of ophthalmoplegia, ataxia, and confusion. However only 10 % of patients present with all threefeatures and other symptoms may also be present. It is commonly regarded as a condition occurring due tomalnourishment due to alcohol use but a variety of other diseases can also lead to it. It is present in thegeneral population with a prevalence of around 2%. We present herewith a case of a 72 years old lady thatpresented with WE

ABSTRACT

BACKGROUND: The previous studies have demonstrated the reduction of thiamine diphosphate is specific to Alzheimer's disease (AD) and causal factor of brain glucose hypometabolism, which is considered as a neurodegenerative index of AD and closely correlates with the degree of cognitive impairment. The reduction of thiamine diphosphate may contribute to the dysfunction of synapses and neural circuits, finally leading to cognitive decline. RESULTS: To demonstrate this hypothesis, we established abnormalities in the glucose metabolism utilizing thiamine deficiency in vitro and in vivo, and we found dramatically reduced dendrite spine density. We further detected lowered excitatory neurotransmission and impaired hippocampal long-term potentiation, which are induced by TPK RNAi in vitro. Importantly, via treatment with benfotiamine, Aß induced spines density decrease was considerably ameliorated. CONCLUSIONS: These results revealed that thiamine deficiency contributed to synaptic dysfunction which strongly related to AD pathogenesis. Our results provide new insights into pathogenesis of synaptic and neuronal dysfunction in AD.

ABSTRACT

The migraine headache is a disease related to the neurovascular system, which affects 10%–20% of people, worldwide. Recent evidences suggested a relation between thiamine status and migraine headaches. The current study was undertaken to assess dietary intake of the thiamine in migraine patients and to evaluate its association with the frequency of migraine attacks. In a case-control design, the current study was performed on 50 migraine patients and 50 healthy people, 20–60 years old in Isfahan, Iran, in 2017. Information about dietary intake was collected by Food frequency questionnaire and analyzed using the Nutritionist version 4 (N4) software (Tinuviel Software). Information about the history of disease was collected by demographic questionnaire. Analysis of covariance and independent t-test were used for data analysis and p value less than 0.05 was considered significant. Mean age, weight, height, and body mass index of participants were 35.1 ± 9.8 years, 65.3 ± 10.4 kg, 162.5 ± 8.4 cm, and 24.7 ± 4.0 kg/m², respectively. Dietary intake of thiamine among the migraine patients was lower than that in the healthy participants (p < 0.001). Migraine patients with the high frequency attacks had significantly lower intake of thiamine compared with moderate frequency attacks group (p = 0.010), however, it was not significant after adjusting for energy intake (p = 0.410, p = 0.240). Dietary intake of thiamine in migraine patients was not significantly different in comparing with healthy subjects. In addition, no significant correlation between thiamine intake and the frequency of migraine attacks was observed.

ABSTRACT

Metronidazole-induced encephalopathy (MIE) can be caused by excessive dose or prolonged metronidazole administration. The signal abnormalities in the cerebellar dentate nuclei, midbrain, dorsal pons and corpus callosum on magnetic resonance imaging are considered as the characteristic feature of MIE. Although the mechanism of MIE remains to be elucidated, various hypothesis have been proposed including the role of metronidazole as a thiamine antagonist. Here we report a 58-year-old woman with MIE who coincidentally presented with thiamine deficiency.
