What is the optimum thiamine dose to treat or prevent Wernicke's encephalopathy or Wernicke-Korsakoff syndrome? Results of a randomized controlled trial.

Alcohol Clin Exp Res 2022 Jun 10;46(6):1133-1147. Epub 2022 May 10.

Melbourne School of Psychological Sciences, University of Melbourne, Parkville, Victoria, Australia.

Background: The primary cause of Wernicke-Korsakoff syndrome (WKS) is thiamine deficiency, and more than 90% of cases are reported in alcohol-dependent patients. While observational studies show parenteral thiamine administration drastically reduced WKS-related mortality, relevant treatment trials have never been conducted to determine the optimum thiamine dose.

Methods: Two double-blind, parallel groups, randomized controlled trials (RCTs) were conducted to determine the optimal thiamine dose required for (1) the prevention of Wernicke's encephalopathy (WE), the acute phase of WKS, in asymptomatic but "at-risk" alcohol misuse patients (Study 1) and (2) the treatment of WE in symptomatic alcohol misuse patients (Study 2).

Disinhibition-Like Behavior Correlates with Frontal Cortex Damage in an Animal Model of Chronic Alcohol Consumption and Thiamine Deficiency.

Biomedicines 2022 Jan 25;10(2). Epub 2022 Jan 25.

Department of Psychobiology and Methods in Behavioral Sciences, Faculty of Psychology, Complutense University of Madrid (UCM), 28223 Madrid, Spain.

Wernicke-Korsakoff syndrome (WKS) is induced by thiamine deficiency (TD) and mainly related to alcohol consumption. Frontal cortex dysfunction has been associated with impulsivity and disinhibition in WKS patients. The pathophysiology involves oxidative stress, excitotoxicity and inflammatory responses leading to neuronal death, but the relative contributions of each factor (alcohol and TD, either isolated or in interaction) to these phenomena are still poorly understood.

Beriberi Neuropathy Mimicking Guillian-Barre Syndrome in a Teenager With Food Restriction: A Case Report.

Cureus 2022 Jan 19;14(1):e21417. Epub 2022 Jan 19.

Child Neurology and Neurodevelopmental Disabilities, West Virginia University Medicine, Morgantown, USA.

Beriberi neuropathy (thiamine deficiency) and Guillian-Barre Syndrome (GBS) both can present with areflexia and progressive ascending weakness. A physical examination can be equivocal between the two. In cases where GBS is suspected clinically but initial work-up with cerebral spinal fluid (CSF) studies and magnetic resonance imaging (MRI) of the spine are not diagnostic, nerve conduction study/electromyography (NCS/EMG) should be done to evaluate beriberi neuropathy.
