INTRODUCTION:

Vitamin-D plays a role regulating the immune response against to viral infection. In this sense, vitamin-D deficiency may confer increased susceptibility to enveloped virus infection such as

  • HIV,

  • Hepatitis,

  • Dengue and

  • Respiratory Syncytial virus infection, among others.

Vitamin D activity is mediated by its receptor (VDR), which acts as a transcription factor modulating the expression of genes triggering the response against viruses. To date, six major VDR polymorphisms (Cdx, A1012G, FokI, BsmI, ApaI and TaqI) have been studied in the context of viral infection susceptibility. Reported studies show controversial results probably due to statistical lack of power and population genetic differences.

AIMS: To do a systematic review of the published data and to perform a meta-analysis examining the role of six VDR polymorphisms on infection susceptibility to enveloped virus.

RESULTS: From all markers and virus considered an association of FokI polymorphism with RSV infection emerges as significant. The worldwide distribution of risk T-allele reveals a lower prevalence in African populations that runs parallel with the relative lower incidence of RSV-associated severe ALRI in children <1 year described in African samples.

CONCLUSION: The results disclose FokI polymorphism as a relevant variant capturing the association of VDR polymorphisms with viral infection.
