The purpose of this cross-sectional study was to assess the prevalence of thiamine deficiency in HD patients and its association with clinical parameters.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>This was a single-center cross-sectional study that included 113 maintenance HD patients from our hospital. Thiamine status was evaluated by high-performance liquid chromatography on whole blood samples. We evaluated the association between blood thiamine concentration and other clinical parameters, including markers of iron metabolism and cardiac function.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The prevalence of thiamine deficiency was 11.5%. Univariate analysis revealed a significant positive correlation between thiamine levels and iron metabolism markers, including hemoglobin level (Rho\u202f=\u202f0.257, <jats:italic>p<\/jats:italic>\u202f=\u202f0.006), transferrin saturation (Rho\u202f=\u202f0.244, <jats:italic>p<\/jats:italic>\u202f=\u202f0.009), and serum iron (Rho\u202f=\u202f0.213, <jats:italic>p<\/jats:italic>\u202f=\u202f0.025). A multivariate regression analysis confirmed that thiamine levels were independently associated with hemoglobin levels (beta coefficients\u202f=\u202f0.25, <jats:italic>p<\/jats:italic>\u202f=\u202f0.012).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>These findings suggest an association between lower thiamine levels and anemia in HD patients.
