Abstract
The intent of this study was an evaluation of our effort to reduce the incidence of hypercalcemia in critically ill vitamin D-deficient patients with multiple traumatic injuries given cholecalciferol. Vitamin D deficiency was defined as a serum 25-hydroxy vitamin D concentration (25-OH vit D) of <20 ng/mL. Adult patients (>17 years of age) were given 10,000 IU of cholecalciferol daily with an intended target 25-OH vit D of >19.9 ng/mL. These patients were compared to a historical control group that underwent therapy with a higher target of >29.9 ng/mL. Patients received cholecalciferol via the feeding tube along with enteral nutrition (EN) until the target 25-OH vit D was achieved, EN discontinued, the nutrition support service signed off the patient, or the patient was discharged from the TICU. Patients were included if two consecutive weekly 25-OH vit D were measured. One hundred and three critically ill trauma patients were retrospectively studied. Fifty were given cholecalciferol therapy with the new lower target 25-OH vit D, and 53 were from a historical cohort aiming for the higher target. Hypercalcemia (serum ionized calcium concentration > 1.32 mmol/L) was reduced from 40% (21 out of 53 patients) to 4% (2 out of 50 patients; p < 0.001). None of the hypercalcemic patients were symptomatic. Readjustment of target 25-OH vit D concentration resulted in a ten-fold decrease in the rate of hypercalcemia and improved the safety of cholecalciferol therapy for critically ill patients with traumatic injuries.

Garner KM, Zavala S, Pape KO, Walroth T, Reger M, Thomas W, Hoyte B, Adams B, Hill DM. A multicenter study analyzing the association of vitamin D deficiency and replacement with infectious outcomes in patients with burn injuries. Burns 2021; 48:1319-1324. [PMID: 34903417 DOI: 10.1016/j.burns.2021.10.020] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2021] [Revised: 10/26/2021] [Accepted: 10/29/2021] [Indexed: 11/02/2022]
Abstract
Vitamin D (25OHD) deficiency is associated with poor outcomes in intensive care populations. The primary objective of this 7-center study was to determine if 25OHD deficiency is associated with infectious outcomes in adult burn patients. Generalized linear mixed modeling was used to control for center effect, percent total body surface area burn (% TBSA), age, and presence of inhalation injury. A total of 1147 patients were initially included (admitted January 2016 through August 2019). After exclusions, 234 (56.8%) in the deficient (25OHD < 20 ng/mL) and 178 in the non-deficient group (25OHD ≥ 20 ng/mL) remained, surpassing a priori power requirements. The non-deficient group had their concentration drawn earlier (p < 0.001), were more likely to be male (p = 0.006), Caucasian (p < 0.001), have lower body mass index (p = 0.009), lower % TBSA (p = 0.002), and taking a 25OHD supplement prior to admission (p < 0.001). Deficient patients were more likely to have an infectious outcome (52.1% vs 36.0%, p = 0.002), acute kidney injury with renal replacement therapy (p = 0.009), less ventilator free days in the first 28 days (p < 0.001), and vasopressors (p = 0.01). After controlling for center, % TBSA, age, and inhalation injury the best model also included presence of deficiency (OR 2.425 [CI 1.206-4.876]), days until 25OHD supplement initiation (OR 1.139 [CI 1.035-1.252]), and choice of cholecalciferol over ergocalciferol (OR 2.112 [CI 1.151-3.877]). To the authors' knowledge, this is the first multicenter study to evaluate the relationship between 25OHD and infectious complications in burn patients.
