High dose Vitamin D may help prevent influenza in infants


High dose Vitamin D may help prevent influenza in infants

Dr.Zhou J et al.  conducted a randomised, open, controlled trial and found that in infants High dose Vit D may provide protection against seasonal influenza.The results that Vitamin D may help prevent and/or ameliorate influenza in infants <1 year are important and significant because Infants <1 year face higher risks for influenza complications than other age groups and FDA-approved influenza vaccines are not approved for infants.The new study has been published in the Journal of  Pediatric Infectious Disease.

 The Researchers randomly assigned 400 healthy infants aged 3-12 months to receive 400 or 1200 IU oral vitamin D3 daily for 4 months (n=168 and 164, respectively), then followed up for 4 months.They assessed serum calcium, inorganic phosphorus, and 25-hydroxyvitamin D levels thrice in 4 months. Infants who developed flu-like illness were checked for influenza virus; however, those testing positive were not given antivirals.Of 232 infants, 157 developed influenza-like symptoms. Of 157 infants, 121 were diagnosed with influenza A.

It was found that incidences of influenza were significantly higher in the low-dose vitamin D group vs the high-dose vitamin D group (46.4% vs 26.2%; P=.0001). Mean duration of fever (P=.0161), coughing (P=.0000), and wheezing (P=.0018) was shorter in the high-dose vitamin D group vs the low dose vitamin D group. In the high-dose vitamin D group, viral load was significantly lower and serum vitamin D level was significantly higher vs low-dose vitamin D group (P<.05 for both).

The researchers concluded that High-dose vitamin D (1200 IU) is suitable for the prevention of seasonal influenza as evidenced by rapid relief from symptoms, rapid decrease in viral loads, and disease recovery. In addition, high-dose vitamin D is probably safe for infants.Vitamin D upregulates antiviral peptides, could help prevent influenza in this population.“Although the mechanism underlying influenza seasonality has not been clearly established, vitamin D has received attention because influenza is more common during winter season when sun exposure is low, which results in low level of vitamin D,’’ the authors wrote.
