Vitamin D deficiency may lead to MRSA infection
A study in the March 8, 2010 issue of Scandinavian Journal of Infectious Diseases suggests that maintaining sufficient vitamin D in the blood may help prevent the nasal colonization of methicillin-resistant Staphylococcus aureus or MRSA.
Vitamin D deficiency has been associated with higher risk of infection like flu including swine flu. One way for the sunshine vitamin to boost the immunity is enhancing the releasing of antimicrobial peptides in the skin.
The current study was meant to examine whether low serum vitamin D levels may increase the risk of nasal carriage of MRSA.
Matheson E.M. and colleagues from Medical University of South Carolina in Charleston, South Carolina analyzed data from the National Health and Nutrition Examination Survey 2001 to 2004 and found about 1.2 percent of the population carries MRSA while 28.3 percent were vitamin D deficient.
They found that people with vitamin D deficiency (serum vitamin D less than 20 ng per mL) had a statistically significant increased risk of MRSA.
