The majority of the patients with multiple sclerosis (MS) experience fatigue. Some observations indicate that fatigue and related manifestations concomitant with MS could be associated with an intracellular mild thiamine deficiency. We recruited 15 patients with MS who also experience fatigue and assessed the severity of the fatigue using the Fatigue Severity Scale. Although blood thiamine and ...
Both thiamine disulfide and O-benzoyl thiamine disulfide, which are thiolfrom derivatives of thiamine, strongly inhibited thiamine transport in Saccharomyces cerevisiae. The inhibition appeared to be due to a high affinity of the analogs for yeast cell membranes, in which thiamine transport component(s) may be integrated.
Background Central venous oxygen saturation (ScvO2) reflects the balance of oxygen delivery and consumption. Low ScvO2 indicates the presence of inadequate oxygen delivery, while high ScvO2 indicates reduced oxygen consumption and is sometimes associated with a high mortality rate in critically ill patients from dysoxia. Thiamine is an essential cofactor in cellular aerobic metabolism. Thiamine...
Aims: To assess the effect of mandatory thiamine enrichment of wheat flour on blood thiamine levels in an alcoholdependent population. Methods: Alcohol-dependent clients (n = 100) entering an inpatient service for the management of alcohol withdrawal had thiamine blood tests and diet interviews. Approximately half (n = 46) the alcohol-dependent participants reported taking vitamin supplements p...
Thiamine responsive megaloblastic anemia (TRMA), also known as Roger syndrome is an autosomal recessive disorder resulting from the deficiency of thiamine (Vitamin B1) transporter protein. This is the report of a 3- year follow up of a female child who presented in 2000 at the age of 11 with severe anemia, congenital deafness and diabetes mellitus. In our follow-up period we prescribed 100-mg...
BACKGROUND Lipid-soluble thiamine precursors have a much higher bioavailability than genuine thiamine and therefore are more suitable for therapeutic purposes. Benfotiamine (S-benzoylthiamine O-monophosphate), an amphiphilic S-acyl thiamine derivative, prevents the progression of diabetic complications, probably by increasing tissue levels of thiamine diphosphate and so enhancing transketolase ...
Thiamine pyrophosphokinase transfers a pyrophosphate group from a nucleoside triphosphate, such as ATP, to the hydroxyl group of thiamine to produce thiamine pyrophosphate. Deficiencies in thiamine can result in the development of the neurological disorder Wernicke-Korsakoff Syndrome as well as the potentially fatal cardiovascular disease wet beriberi. Pyrithiamine is an inhibitor of thiamine m...
Background: Traditionally, vitamin B₁ status is assessed by a functional test measuring erythrocyte transketolase (ETK) activity or direct measurement of erythrocyte thiamine diphosphate (eThDP) concentration. However, such analyses are logistically challenging, and do not allow assessment of vitamin B₁ status in plasma/serum samples stored in biobanks. Using a multiplex assay, we evaluated pla...
Chloroethylthiamine was found to inhibit an entrapment of thiamine as thiamine monophosphate by blocking thiamine monophosphokinase in the cytoplasm after thiamine was taken up by the cells of Escherichia coli.
Recent pet food recalls for insufficient dietary thiamine have highlighted the importance of adequate thiamine intake in dogs and cats, as thiamine is an essential dietary nutrient with a critical role in energy metabolism. Prolonged thiamine deficiency leads to clinical signs that can span several organ systems, and deficiency can be fatal if not reversed. In this review, the current knowledge...
