Summary by Claude - June 2026
Among 829 mostly very elderly hospital patients (median age 81) with confirmed sepsis, those with higher vitamin D at admission were more likely to survive and recover faster — and the level still predicted outcome after adjusting for age, illness severity (NEWS2), comorbidity (Charlson index), CRP, lactate, and procalcitonin.
This is a secondary analysis of a prospective multicenter observational cohort (five Italian hospitals), not a treatment trial. A single baseline 25(OH)D was measured by chemiluminescence. The population was severely deficient across the board — median 25(OH)D just 11.2 ng/mL (28 nmol/L) — so this study compares degrees of deficiency, not deficiency versus sufficiency.
Key results: 7-day mortality showed no link to vitamin D, and 30-day mortality lost significance after adjustment. Only 90-day mortality and discharge alive within 15 days held up. Patients dying within 90 days had a median of 9.6 ng/mL versus 12.0 ng/mL in survivors. Using a 12 ng/mL cut-off, those at or above it had about 40% lower odds of 90-day death (OR 0.596, 95% CI 0.407–0.874) — equivalently, patients below 12 ng/mL had about 1.7X the odds of 90-day death and ~61% higher odds of early discharge (OR 1.606, 1.174–2.196).
The authors are candid that vitamin D alone discriminates poorly (AUC 0.579) and is best used alongside existing risk scores, as a marker of immune reserve/frailty — and that the late-outcome signal fits the "post-sepsis" PICS syndrome.
What this does NOT show / limitations: This is association, not causation — low vitamin D may simply flag frailer, less-mobile, poorly-nourished patients. Endpoints were not pre-specified (exploratory). The 12 ng/mL threshold is internal to this cohort and unvalidated, and is not a health target. A single admission level can be depressed by acute inflammation, and no PTH, frailty, nutrition, or supplementation data were available. Crucially, this study does not show that giving vitamin D improves sepsis outcomes; the cited ICU supplementation trials (VITdAL-ICU, PETAL/VIOLET) were conflicting/null and were not aimed at elderly septic patients.
