The interrelation between these conditions remains to be fully elucidated. VD, known for its immunomodulatory properties, is suspected to play a role in the pathogenesis of both sepsis and sarcopenia. The significance of serum VD levels in diagnosing sepsis and sarcopenia is well-recognized. This study was designed to scrutinize the relationships among VD, nutritional status, and inflammatory profiles in individuals with sepsis and concurrent sarcopenia, and to explore potential VD cut-off values.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>The study cohort comprised two principal groups: a sepsis group and a control group. The sepsis group was further bifurcated into those with and without sarcopenia. The study enrolled 100 patients diagnosed with sepsis from February 2022 to February 2023, and 92 healthy controls. Of the sepsis patients, 46 had comorbid sarcopenia. Serum 25(OH)D levels, along with nutritional and inflammatory biomarkers, were assessed, and receiver operating characteristic (ROC) curve analysis was performed to determine the optimal cut-off values.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Notable disparities in 25(OH)D levels and markers of nutrition and inflammation were observed between the sepsis and control groups, as well as between the subgroups with and without sarcopenia. The optimal cut-off values of serum 25(OH)D derived from ROC analysis were 22.55\u202fng\/mL for sepsis and 14.31\u202fng\/mL for sepsis with sarcopenia.<\/jats:p>\n                  <\/jats:sec>\n
