Supplementation with vitamin D could help to reverse deficiencies in the sunshine vitamin that are impacting ICU infection rates and increasing the length of hospital stays, according to the researchers.

Vitamin D deficiency is linked to an increased risk of infection in neurosurgical intensive care unit patients, according to new research that backs supplementation to improve immune status and fight off infection.

The study, published in Neural Regeneration Research, measured levels of the sunshine vitamin in a small number of patients from a neurosurgical intensive care unit and investigated the possible relationships between vitamin D status and other factors such as infection and length of intensive care unit admission.

“Vitamin D deficiency in neurosurgical intensive care unit patients is an important issue,” said the researchers – led by Je Hoon Jeong from Soon Chun Hyang University Bucheon Hospital in South Korea.

“In this study, we found that vitamin D deficiency is linked to immunological status,” they explained – revealing that vitamin D status was linked to blood levels of immune cells and was also associated with the length of stay in hospital.

“As such, continuous monitoring and checking of vitamin D levels is very important in patients admitted to the neurosurgical intensive care unit,” said the authors – who suggested that supplementation with vitamin D “can help improve the immunological status of patients in the neurosurgical intensive care unit.”

Study details

Hoon Jeong and colleagues measured serum levels of vitamin D in 15 patients with clinically suspected infection and 10 patients with confirmed infection, who came from neurosurgical intensive care unit.

The team found that serum level of 25-hydroxyvitamin D - the primary circulating form of vitamin D - was significantly decreased in patients with suspected or confirmed infection after a 2-week neurosurgical intensive care unit hospitalization, while serum level of 1,25-dihydroxyvitamin D - the active form of vitamin D - was significantly decreased in patients after a 4-week neurosurgical intensive care unit hospitalization.

Analysis also revealed that white blood cell count and neutrophil percentage showed a tendency to increase, while vitamin D levels were simultaneously decreasing, said the authors.

“Vitamin D deficiency was present in neurosurgical intensive care unit patients and was more severe in cases of long-term hospitalization,” the team added.

“Vitamin D deficiency also correlated with long-term intensive care unit hospitalization, increasing the infectious disease rate in our research.”

Choosing the right enteral feeding formula

Standard enteral formulas meet basic macro- and micronutrient needs; therapeutic enteral formulas meet these basic needs and also contain specific pharmaconutrients that may attenuate hyper inflammatory responses, enhance the immune responses to infection, or improve gastrointestinal tolerance.

Choosing the right enteral feeding formula may positively affect a patient’s outcome; targeted use of therapeutic formulas can reduce the incidence of infectious complications, shorten lengths of stay in the ICU and in the hospital, and lower risk for mortality.
