OBJECTIVE: Sepsis is a life-threatening disease resulting from the interaction between pathogen and host response; its dysregulation causes organ dysfunction, high morbidity, and mortality. Despite the increase of septic patients admitted to Internal Medicine wards, data about clinical predictors of mortality in this setting are still lacking. The aim of this study was to evaluate the role of MEDS score and vitamin D as predictors of mortality (28-day and 90-day) in septic patients admitted to the Internal Medicine department.
PATIENT S AND METHODS: Prospectively collected clinical data, lab tests including vitamin D, and clinical scores (SIRS, MEDS, SCS, REMS, SOFA, qSOFA) were retrospectively analyzed. Eighty-eight microbiologically identified septic patients (median age 75 years old, IQR 65-82 years old; range 37-94 years old) were evaluated.
RESULTS: Twenty-three patients (26.1%) died at 28 days, 33 (37.5%) died at 90 days. The logistic regression showed a positive effect of MEDS score (p=0.006; OR 1.24, 95% CI 1.08-1.49), and a negative effect of low vitamin D levels (p=0.008, OR 0.83, 95% CI 0.72-0.94) on mortality. Moreover, the cut-off of 7 points for MEDS score and of 7 ng/ml for vitamin D levels significantly predicted poor prognosis at 28 and 90 days.
CONCLUSIONS: MEDS score and vitamin D levels represent independent predictors of mortality in a cohort of Internal Medicine septic patients. Further studies on larger samples are needed to confirm our results and to clarify the pathophysiological mechanisms at the basis of vitamin D deficiency as a predictor of mortality in septic patients.
