Of these, we considered those who presented at least 2 of the 3 signs of the classic triad: encephalopathy, ophthalmoplegia and/or nystagmus and ataxia. Patients with a history of alcoholism were excluded. Finally, we included 8 patients (4 men and 4 women). We recorded their medical histories, especially gastrointestinal antecedents, presentation symptoms, neurological findings, delay between symptom onset and diagnosis, cranial MRI findings, plasma levels of thiamine, response to treatment and presence of residual deficits. Patients were considered as with no sequelae or mild sequelae when they had a score ≤3 on the Modified Rankin Scale<a class="elsevierStyleCrossRef" href="#bib0035"><span class="elsevierStyleSup">7</span></a> and with a normal cognitive status or mild cognitive impairment (according to the Petersen<a class="elsevierStyleCrossRef" href="#bib0040"><span class="elsevierStyleSup">8</span></a> criteria), and with severe sequelae when they presented a score above 3 or suffered a greater cognitive impairment than mild.

She was admitted due to subacute cognitive impairment with memory deficit, disorientation and apraxia after vomiting for 2 weeks, which was attributed to pyloric stenosis. Upon admission, she presented a limitation of the upward gaze and bilateral abduction, horizontal and vertical nystagmus, and ataxia. She also presented progressive bilateral ptosis, decreased bilateral visual acuity, distal hypoesthesia, anterograde amnesia, mild right dysmetria, mild right hemiparesis and areflexia of the lower limbs. Due to the presence of the classic triad, WE was suspected. Thiamine levels were measured and appeared to be low, so thiamine was administered. The time between the onset of clinical symptoms and diagnosis was 59 days. The MRI scan showed signal alterations in cortical regions, diencephalon, mammillary bodies, periaqueductal area and cerebellum. Pyloric stenosis improved with <span class="elsevierStyleItalic">Helicobacter pylori</span> eradication therapy. The initial response to thiamine was good, with improvement of oculomotor deficits and hemiparesis; however, disorientation, ataxia and amnesia lingered.

Exploration found anterograde amnesia, disorientation and horizontal nystagmus in all directions (but without ophthalmoplegia), clumsiness of the right hand, left dysmetria and mild hemiparesis, hypopallesthesia and areflexia in the lower limbs. He was given thiamine due to suspicion of WE, but levels were not determined. The time from the onset of neurological symptoms to diagnosis was 6 days. An MRI scan showed signal alterations in cortical, diencephalic, periaqueductal and mammillary regions.

Of these, 7 presented a medical history of gastrointestinal pathology and 3 had a history of current neoplastic processes. Persisting vomiting was the trigger in all except 1 case. The initial symptom was encephalopathy in 4 patients, ataxia in 2, diplopia in 1 and papilloedema in another. The classic triad of encephalopathy, oculomotor alterations and ataxia appeared in all patients except in 1, who did not present ataxia. The most commonly affected cranial nerve was the third (4 patients) and all patients suffered nystagmus. Other common neurological signs were dysmetria (5), hemiparesis (5), hypopallesthesia (2) and impaired reflexes (5 with areflexia, 1 with hyperreflexia).</p><p id="par0095" class="elsevierStylePara elsevierViewall">Thiamine levels were determined in 6 of the 8 patients. They were low in 3 of them and normal in the other 3. The initial MRI was abnormal in all 7 cases in which it was performed, showing hyperintensity on T2 and FLAIR sequences, although hypointensity in T1 was also detected in 3 patients and gadolinium-enhanced lesions were found in 2 patients. The most affected regions were the diencephalon and the mammillary bodies (7), followed by the periaqueductal grey matter (6), cortex (3) and cerebellum (1). A control MRI was performed on 4 patients. This showed residual atrophy of the mammillary bodies in 2 cases (with improvement of the remaining lesions in 1 and persistence in the other) and was normal in the other 2 cases (resolution of lesions in 1 case, while the other had not undergone an initial MRI scan).</p><p id="par0100" class="elsevierStylePara elsevierViewall">Thiamine treatment was administered to all patients, with partial clinical improvement in 7 of them. At 6–12 months follow-up, 5 of them presented mild sequelae and 3 presented severe sequelae. The 3 patients with severe sequelae had suffered a diagnostic delay of 18 or more days, while patients with mild sequelae had suffered a diagnostic delay of less than 18 days.</p></span><span id="sec0060" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle">Discussion</span><p id="par0105" class="elsevierStylePara elsevierViewall">Wernicke's encephalopathy is due to thiamine deficiency. Thiamine, in its biologically active form (pyrophosphate), is an essential coenzyme in the metabolism of glucose in the brain.<a class="elsevierStyleCrossRef" href="#bib0045"><span class="elsevierStyleSup">9</span></a> The mechanism through which its deficit causes brain lesions is unknown, although it is believed that neuronal damage begins once the metabolism in brain regions with high metabolic requirements and high thiamine turnover is inhibited.</p><p id="par0110" class="elsevierStylePara elsevierViewall">It is important to note that most WE patients do not present the classic triad<a class="elsevierStyleCrossRefs" href="#bib0005"><span class="elsevierStyleSup">1,2</span></a> and that thiamine levels can be normal in some patients, whereas the MRI scan almost always shows characteristic alterations. Therefore, other causes for WE should be suspected when faced with a patient suffering acute confusional syndrome or acute or subacute ataxia or oculomotor alteration, with or without other neurological symptoms, especially in the context of vomiting, gastrointestinal or neoplastic history. The EFNS<a class="elsevierStyleCrossRef" href="#bib0010"><span class="elsevierStyleSup">2</span></a> recommends determining thiamine levels just before starting treatment (good clinical practice) and performing an MRI scan to support the diagnosis (grade B recommendation). According to a clinical-pathological study in alcoholic patients with WE, clinical diagnosis requires the presence of at least 2 of the following signs: nutritional deficiencies, ocular disorders, cerebellar dysfunction and altered mental status or mild memory impairment (grade B recommendation), which achieves a diagnostic sensitivity of 85%.<a class="elsevierStyleCrossRef" href="#bib0010"><span class="elsevierStyleSup">2</span></a> The EFNS considers applying the same criteria to non-alcoholic patients reasonable (good clinical practice). All these signs were present in the patients in this series, except in 1 who had no cerebellar signs, which is consistent with the recommendation. Although nutritional deficit is not as evident in non-alcoholic patients, perhaps special attention should be paid to a history of vomiting.</p><p id="par0115" class="elsevierStylePara elsevierViewall">Reversible cytotoxic oedema seems to be the most distinctive lesion in WE and the most useful sequences to detect it are T2, FLAIR and DWI.<a class="elsevierStyleCrossRefs" href="#bib0050"><span class="elsevierStyleSup">10,11</span></a> The typical lesions are symmetrical and can be observed in the thalamus, mammillary bodies, tectal plate and periaqueductal area. Atypical lesions can be observed in the cerebellum; cerebellar vermis; cranial nerve nuclei: red, dentate, caudate nuclei; splenium; and cerebral cortex.<a class="elsevierStyleCrossRef" href="#bib0055"><span class="elsevierStyleSup">11</span></a> The atypical locations have been described mostly in non-alcoholic patients and associated with typical alterations, while gadolinium uptake in the thalamus and mammillary bodies is more common in alcoholics. In the patients of this series, the most affected regions were the typical locations of diencephalon and mammillary bodies (7) and the periaqueductal grey matter (6), followed by the atypical locations of cortex (3) and cerebellum (1). In the latter, the atypical alterations were also associated with alteration in the 3 typical locations. The MRI appears to be more sensitive in detecting WE lesions in non-alcoholic than in alcoholic patients. In a retrospective study in alcoholic patients, the sensitivity and specificity results obtained were 53% and 93%, with a positive predictive value of 89%.<a class="elsevierStyleCrossRef" href="#bib0060"><span class="elsevierStyleSup">12</span></a> Pooled data from several studies show that conventional MRI was able to detect changes in two-thirds of the alcoholic subjects with WE. The FL2AIR and DWI images did not provide further information.

This suggests that atrophy of the mammillary bodies is not a finding unique to alcoholic WE and that it can develop in a short time.</p><p id="par0125" class="elsevierStylePara elsevierViewall">It is common for residual deficits to persist in alcoholic patients with WE.<a class="elsevierStyleCrossRef" href="#bib0015"><span class="elsevierStyleSup">3</span></a> Oculomotor alterations usually improve in a few hours after administering thiamine, but nystagmus persists in 60% of cases. Only 40% of patients recover from ataxia and over half of patients are left with residual gait disorder. Acute encephalopathy is resolved slowly, but learning deficit and recent memory remain (Korsakoff's psychosis), which are only resolved in 20%.</p><p id="par0130" class="elsevierStylePara elsevierViewall">Except for 1 case, the cause of WE was persistent vomiting due to different causes, mainly gastrointestinal in all patients in this series. The mechanism must have been a decrease in the absorption of thiamine. In the absence of thiamine, the body reserve is depleted within 2–3 weeks, affecting the most vulnerable brain regions, and the plasma levels decrease after 3 weeks.<a class="elsevierStyleCrossRef" href="#bib0020"><span class="elsevierStyleSup">4</span></a> However, this reserve can be particularly low in some individuals or be consumed quickly, as in the case of Patient 2, who developed a case of WE after only 5 days of vomiting.</p><p id="par0135" class="elsevierStylePara elsevierViewall">It is likely that some people who present a genetically lower transketolase activity have a higher thiamine requirement and are therefore more predisposed to suffer WE in situations of higher demand or lower absorption. A higher genetic predisposition has been described in identical twins,<a class="elsevierStyleCrossRef" href="#bib0045"><span class="elsevierStyleSup">9</span></a> as well as an altered affinity of the transketolase enzyme for thiamine.<a class="elsevierStyleCrossRef" href="#bib0080"><span class="elsevierStyleSup">16</span></a> Phenotypic variants have also been detected in the thiamine transporter gene.<a class="elsevierStyleCrossRef" href="#bib0085"><span class="elsevierStyleSup">17</span></a> It is essential to start treatment as soon as possible, since a delay may lead to more severe sequelae or further irreversible damage. This is reflected in the fact that the 3 patients with severe sequelae were those who had a diagnostic delay of 18 or more days, while patients with mild sequelae were those diagnosed within 18 days. Thiamine treatment was administered at the time WE was suspected. The delay in diagnosis was due to the fact that, at the onset, patients usually present only 1 or 2 WE symptoms, which in addition are non-specific and could be related to the underlying disease. Thus, WE is often not suspected until the classic triad appears or a suggestive image is identified in MRI. Therefore, we must insist on increasing the level of suspicion in patients at risk.</p><p id="par0140" class="elsevierStylePara elsevierViewall">In conclusion, in alcoholic patients with WE, it is common to find the presence of a gastrointestinal history that could condition lower absorption of thiamine. This would be a physiopathogenic factor in patients with genetic susceptibility. While the levels of thiamine may be normal in many cases, the MRI almost always shows signal alterations in typical locations, thus being more effective for the diagnosis. A delay in diagnosis and, therefore, in treatment can worsen the prognosis.</p></span><span id="sec0065" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle">Conflict of interests</span><p id="par0145" class="elsevierStylePara elsevierViewall">The authors have no conflict of interests to declare.</p></span></span>" "textoCompletoSecciones" => array:1 [ "secciones" => array:10 [ 0 => array:2 [ "identificador" => "xres169578" "titulo" => array:5 [ 0 => "Abstract" 1 => "Introduction" 2 => "Patients and methods" 3 => "Results" 4 => "Conclusions" ] ] 1 => array:2 [ "identificador" => "xpalclavsec157689" "titulo" => "Keywords" ] 2 => array:2 [ "identificador" => "xres169577" "titulo" => array:5 [ 0 => "Resumen" 1 => "Introducción" 2 => "Pacientes y métodos" 3 => "Resultados" 4 => "Conclusiones" ] ] 3 => array:2 [ "identificador" => "xpalclavsec157688" "titulo" => "Palabras clave" ] 4 => array:2 [ "identificador" => "sec0005" "titulo" => "Introduction" ] 5 => array:3 [ "identificador" => "sec0010" "titulo" => "Patients and methods" "secciones" => array:8 [ 0 => array:2 [ "identificador" => "sec0015" "titulo" => "Patient 1" ] 1 => array:2 [ "identificador" => "sec0020" "titulo" => "Patient 2" ] 2 => array:2 [ "identificador" => "sec0025" "titulo" => "Patient 3" ] 3 => array:2 [ "identificador" => "sec0030" "titulo" => "Patient 4" ] 4 => array:2 [ "identificador" => "sec0035" "titulo" => "Patient 5" ] 5 => array:2 [ "identificador" => "sec0040" "titulo" => "Patient 6" ] 6 => array:2 [ "identificador" => "sec0045" "titulo" => "Patient 7" ] 7 => array:2 [ "identificador" => "sec0050" "titulo" => "Patient 8" ] ] ] 6 => array:2 [ "identificador" => "sec0055" "titulo" => "Results" ] 7 => array:2 [ "identificador" => "sec0060" "titulo" => "Discussion" ] 8 => array:2 [ "identificador" => "sec0065" "titulo" => "Conflict of interests" ] 9 => array:1 [ "titulo" => "References" ] ] ] "pdfFichero" => "main.pdf" "tienePdf" => true "fechaRecibido" => "2010-11-23" "fechaAceptado" => "2011-03-09" "PalabrasClave" => array:2 [ "en" => array:1 [ 0 => array:4 [ "clase" => "keyword" "titulo" => "Keywords" "identificador" => "xpalclavsec157689" "palabras" => array:6 [ 0 => "Wernicke's encephalopathy" 1 => "Non-alcoholic Wernicke's encephalopathy" 2 => "Gastrointestinal" 3 => "Thiamine" 4 => "Magnetic resonant" 5 => "Prognosis" ] ] ] "es" => array:1 [ 0 => array:4 [ "clase" => "keyword" "titulo" => "Palabras clave" "identificador" => "xpalclavsec157688" "palabras" => array:6 [ 0 => "Encefalopatía de Wernicke" 1 => "Encefalopatía de Wernicke no alcohólica" 2 => "Gastrointestinal" 3 => "Tiamina" 4 => "Resonancia magnética" 5 => "Pronóstico" ] ] ] ] "tieneResumen" => true "resumen" => array:2 [ "en" => array:2 [ "titulo" => "Abstract" "resumen" => "<span class="elsevierStyleSectionTitle">Introduction</span><p id="spar0005" class="elsevierStyleSimplePara elsevierViewall">Wernicke's encephalopathy (WE) is an underdiagnosed condition, usually associated with alcoholism, and has a worse prognosis if there is a delay in diagnosis.
