Introduction: The impact of vitamin B metabolic disorders on hemodialysis (HD) patients' survival is unknown. This study is to investigate the association of serum vitamin B1, B3, B5, and B6 with all-cause and cardiovascular (CV) mortality in HD patients.
Methods: Patients' baseline serum vitamin B1, B3, B5, and B6 levels were collected, and they were followed up for the occurrence of all-cause and CV death. Kaplan-Meier analysis and Cox proportional hazards model were used to examine the association of vitamin B with mortality.
Results: Seventy-six HD patients were included. The median follow-up time was 99 months. Kaplan-Meier analysis showed that baseline vitamin B5 < 69.0 nmol/L and vitamin B6 < 8.1 ng/ml were associated with a higher risk of CV mortality, but these associations were nullified after adjustment.
Conclusions: Serum vitamins B1, B3, B5, and B6 were not associated with all-cause or CV mortality in HD patients.

Vitamin D (VD) is a vital lipophilic secosteroid hormone known for its essential role in maintaining skeletal health and regulating calcium and phosphate metabolism. Recent evidence has begun to illuminate its significance beyond bone health, particularly in relation to thrombosis-a condition characterized by blood clot formation within the vascular system that can lead to serious cardiovascular events such as myocardial infarction and stroke. VD deficiency, defined as a plasma 25-hydroxyVD level below 25 nmol/L, affects a substantial portion of the global population, with prevalence rates ranging from 8% to 18%.
