Thiamine-responsive megaloblastic anemia syndrome
An autosomal recessive disease characterized by megaloblastic anemia, diabetes mellitus, and sensorineural deafness. Onset is typically between infancy and adolescence, but all of the cardinal findings are often not present initially. The anemia, and sometimes the diabetes, improves with high doses of thiamine. Other more variable features include optic atrophy, congenital heart defects, short stature, and stroke.

Microcephaly, Amish type
A disorder characterized by severe congenital microcephaly and severe 2-ketoglutaric aciduria leading to death within the first year.
Catalyzes the phosphorylation of thiamine to thiamine pyrophosphate (TPP) utilizing UTP and therefore links the biosynthesis of TPP to pyrimidines metabolism (PubMed:38547260). By producing thiamine pyrophosphate, a cofactor of the mitochondrial pyruvate dehydrogenase indirectly regulates pyruvate oxidation and lipogenesis (PubMed:38547260). Although it can also catalyze thiamine phosphorylation using ATP and CTP in vitro, it does so with significantly lower efficiency and without physiological
Thiamine metabolism dysfunction syndrome 5, episodic encephalopathy type
An autosomal recessive metabolic disorder due to an inborn error of thiamine metabolism. The phenotype is highly variable, but in general, affected individuals have onset in early childhood of acute encephalopathic episodes associated with increased serum and CSF lactate. These episodes result in progressive neurologic dysfunction manifest as gait disturbances, ataxia, dystonia, and spasticity, which in some cases may result in loss of ability to walk. Cognitive function is usually preserved, although mildly delayed development has been reported. These episodes are usually associated with infection and metabolic decompensation. Some patients may have recovery of some neurologic deficits.

Genetic dissection of stool frequency implicates vitamin B1 metabolism and other actionable pathways in the modulation of gut motility.
Genetic studies of stool frequency (SF), an indirect proxy for gastrointestinal transit, may reveal therapeutically tractable pathways relevant to IBS and other dysmotility disorders. To identify genes and mechanisms involved in gut motility, providing a foundation for clinical translation. We performed a multiancestry genome-wide association study (GWAS) meta-analysis of SF in 268 606 European and East Asian individuals. Heritability and genetic correlations with other traits were estimated, and Mendelian randomisation was used to test causal relationships. GWAS signals were fine-mapped and functionally annotated to prioritise candidate genes and pathways. Findings implicating thiamine metabolism were followed-up with dietary interaction analyses in UK Biobank (UKB). SF heritability was comparable in Europeans (7.0%) and East Asians (5.6%). We observed strong genetic correlations with gastrointestinal and psychiatric disorders (rg=0.18-0.47), and causal effects on IBS. Novel correlations with cardiovascular traits (rg=0.12-0.14) were supported by drug signature enrichment analyses. We identified 21 independent loci, including 10 novel signals implicating bile acid synthesis (KLB) and cholinergic signalling (COLQ). Fine-mapping converged on vitamin B1 metabolism, highlighting single-variant causal effects at SLC35F3 (a thiamine transporter) and XPR1 (phosphate exporter essential for thiamine activation). In 98 449 UKB participants, thiamine intake was positively associated with SF (p<0.0001), and a combined SLC35F3/XPR1 genotype score significantly modulated this effect (p<0.0001). We identify therapeutically tractable mechanisms involved in the control of gut motility, including a previously unrecognised role for vitamin B1. These findings warrant mechanistic and clinical studies to evaluate their translational potential in IBS and other dysmotility syndromes.
Adverse events associated with drug-related thiamine deficiency: A pharmacovigilance study.
Thiamine deficiency can cause severe complications, including beriberi, Wernicke's encephalopathy, and Korsakoff syndrome, potentially leading to irreversible neurological damage or death. While causes such as chronic alcohol use disorder are established, drug-induced thiamine deficiency represents a potential risk that is often overlooked. However, systematic data on this association remain limited. We utilized relevant preferred terms from the Medical Dictionary for Regulatory Activities to identify adverse events in the United States Food and Drug Administration Adverse Event Reporting System from 2004 through 2024. Signal detection was performed using four algorithms: the reporting odds ratio, the proportional reporting ratio, the information component, and the empirical Bayes geometric mean. We identified 1,046 cases of thiamine deficiency, showing an increasing trend. Hospitalization was reported in 46.0% of cases. The median patient age was 55.0 years (interquartile range: 41.0-68.0), and 42.5% were female. Healthcare professionals submitted 81.5% of reports, and the United States contributed the largest share (27.8%). The five agents most frequently reported were furosemide, metformin, fedratinib, metronidazole, and fluorouracil. Overall, 38 drugs demonstrated consistently positive safety signals across all four methods. Additional drugs exhibiting notable signals included arsenic trioxide, torasemide, rabeprazole, and hydrochlorothiazide. This pharmacovigilance analysis identifies safety signals linking specific medications with thiamine deficiency, potentially mediated by mechanisms such as transport inhibition and metabolic interference. These findings highlight the importance of clinical vigilance and the consideration of thiamine monitoring in high-risk patients to mitigate the risk of neurological complications.
Thiamine (Vitamin B1) metabolism in schistosomes.
Schistosomes are intravascular parasitic flatworms that acquire all nutrients necessary for their survival from blood. Here we focus on how the parasites acquire and metabolize an essential nutrient - vitamin B1 (thiamine). Live adult male and female Schistosoma mansoni parasites cleave exogenous thiamine monophosphate (ThMP) and thiamine pyrophosphate (ThPP) to generate free thiamine. Of the three characterized nucleotide-metabolizing ectoenzymes expressed at the schistosome surface (SmAP, SmNPP5, and SmATPDase1), only SmAP hydrolyzes these metabolites. Parasites whose SmAP gene is suppressed by RNAi are significantly impaired in their ability to cleave ThMP, but not ThPP, compared to controls. We conclude therefore that while SmAP can cleave ThMP alone, additional (uncharacterized) ectoenzyme(s) also cleave ThPP. When schistosomes are incubated in murine plasma, levels of both thiamine and phosphate increase over time, a finding consistent with these data. Generating a pool of free thiamine around the worms should permit the convenient uptake of this vital metabolite. However, we were unable to identify homologs in schistosomes of thiamine transporter proteins described in other systems. Instead, a ThPP transporter homolog was identified in silico (SmThPPT). Additionally, a schistosome mitochondrial ThPP transporter homolog is described that likely moves some imported ThPP from the cytoplasm into worm mitochondria. Finally, we report on a thiamine pyrophosphokinase homolog (SmTPK) that could pyrophosphorylate thiamine to make ThPP. Free thiamine generated outside the worms, if not imported (and since it is anti-inflammatory), could act in an immunomodulatory capacity to help generate a more benign external environment for the worms in the bloodstream.
Thiamine Metabolism in Microbes and Strategies for Biomanufacturing.
Thiamine (Vitamin B1), an essential water-soluble vitamin, is composed of a pyrimidine and a thiazole ring. Owing to its functional roles as a coenzyme and its anti-inflammatory and antioxidant properties, it plays a critical role in disease prevention and therapeutic interventions. Currently, industrial production of thiamine relies primarily on chemical synthesis-a process that generates significant amounts of hazardous waste and byproducts. In contrast, microbial biosynthesis represents a more sustainable and environmentally friendly alternative. This review first outlines thiamine metabolism in microorganisms, highlighting ThiC as the key rate-limiting enzyme in its biosynthesis. It then summarizes potential strategies for improving thiamine biomanufacturing, and proposes that optimizing metabolic flux together with energy and cofactor balance at critical nodal points is essential for overcoming current yield limitations. Finally, to overcome specific bottlenecks in thiamine biosynthesis, such as precursor transport and pathway optimization, we propose that transport engineering and gene mining represent promising strategies complementary to recent advances in enzyme-directed evolution and metabolic engineering.
Vitamin A acts as a potent suppressor of selenoprotein P with potential relevance for multivitamin supplementation.
Multivitamin supplementation is a widely used strategy to prevent disease, slow the ageing process, improve quality of life and extend life span, although recent clinical findings do not support these claims. Since selenium (Se) deficiency is associated with morbidity and mortality risk, we tested the hypothesis that certain vitamins interfere with the regular biosynthesis of the Se transporter selenoprotein P (SELENOP). Human liver cancer cells (HepG2) were treated with different concentrations of folic acid, nicotinamide, nicotinic acid, pyridoxal phosphate, thiamine, vitamin A, vitamin C, vitamin D2, vitamin D3, vitamin E, vitamin K and vitamin B12. Secreted SELENOP was quantified by ELISA and characterized by Western blot analysis. SELENOP transcript levels and promoter activity were determined, and resveratrol as a negative and thyroid hormone as a positive modulator were included for comparison. The concentration of extracellular SELENOP decreased twofold in response to micromolar concentrations of vitamin A. The SELENOP transcript concentration decreased to 70% after incubation with 1 µM vitamin A, and a moderate concomitant decrease in SELENOP core promoter activity was observed. Co-incubation experiments of vitamin A with the active thyroid hormone T3 revealed dose-dependent effects and suggested competitive activities of these two modifiers of SELENOP expression in opposite directions. We conclude that vitamin A is able to suppress hepatic SELENOP biosynthesis and secretion, which may confer health risks in self-administered or clinically indicated supplementation with retinoids, especially in individuals with marginal Se intake and status.
