The relationship between thiamine blood level (TBL) and cognition remains uncertain, including among alcohol-dependent persons (ADP).
To evaluate this relationship during protocol-driven inpatient alcohol detoxification treatment including thiamine supplementation (AD + Th).
Prospective 3-week study with 100 consecutively admitted detoxification-seeking ADP (47.7 ± 11 years old, 21% females) without superseding comorbidities requiring treatment. TBL and Montreal Cognitive Assessment (MoCA) were measured at admission (t, pre-AD + Th) and discharge (t, post-AD + Th). Frontal Assessment Battery (FAB) was performed at t. AD + Th included abstinence, pharmacological alcohol withdrawal syndrome treatment, and oral thiamine supplementation (200 mg/day for 14 days). Regression and mediation analyses assessed TBL-cognition relationships.
We found no cases of Wernicke Encephalopathy (WE) and only one case of thiamine deficiency. Both MoCA and TBL significantly improved across AD + Th (with medium-to-large effect sizes). At t, TBL significantly predicted MoCA and FAB sum scores (medium effect sizes; extreme and very strong evidence, respectively). The clear TBL-MoCA association disappeared at t. In multivariate regression and mediation analyses exploring key influential factors of cognition (identified by LASSO regression), the TBL-MoCA interactions did not relevantly change at t and t. Age, serum transaminases, vitamin D levels, drinking-years, and depression score weakly modified the relationship.
TBL was a robust predictor of pre-detoxification cognitive impairment, and both TBL and cognition improved significantly during AD + Th (including abstinence) in our ADP population, supporting routine thiamine supplementation for ADP, even those at low WE-risk. The TBL-cognition relationship was minimally confounded by age, alcohol-toxicity proxies, mood, and vitamin D levels.
硫胺素血水平(TBL)与认知之间的关系尚不确定,包括在酒精依赖者(ADP)中。
在包括硫胺素补充(AD + Th)的协议驱动的住院酒精解毒治疗期间评估这种关系。
前瞻性 3 周研究,连续纳入 100 名寻求解毒的 ADP(47.7 ± 11 岁,21%为女性),无需要治疗的并发疾病。TBL 和蒙特利尔认知评估(MoCA)在入院时(t,AD + Th 前)和出院时(t,AD + Th 后)进行测量。在 t 时进行额叶评估量表(FAB)。AD + Th 包括戒酒、药物戒断综合征治疗和口服硫胺素补充(14 天每天 200mg)。回归和中介分析评估了 TBL-认知关系。
我们没有发现威尼克脑病(WE)的病例,只有一例硫胺素缺乏症。AD + Th 后,MoCA 和 TBL 均显著改善(具有中到大的效应量)。在 t 时,TBL 显著预测 MoCA 和 FAB 总分(中效应量;分别为极端和极强证据)。在 t 时,TBL-MoCA 关联消失。在探索认知的关键影响因素的多元回归和中介分析(由 LASSO 回归确定)中,t 和 t 时 TBL-MoCA 相互作用没有明显变化。年龄、血清转氨酶、维生素 D 水平、饮酒年限和抑郁评分微弱地改变了这种关系。
TBL 是解毒前认知障碍的有力预测因子,在我们的 ADP 人群中,AD + Th(包括戒酒)期间 TBL 和认知都显著改善,支持对 ADP 进行常规硫胺素补充,即使是低 WE 风险的患者。TBL-认知关系受年龄、酒精毒性指标、情绪和维生素 D 水平的影响最小。
