RSV linked to low maternal vit D

SEVERE lower respiratory tract infection in infants due to respiratory syncytial virus (RSV) has been linked to maternal vitamin D deficiency for the first time.

The finding adds to the growing literature linking vitamin D deficiency with a range of health issues.

Strategies to improve maternal vitamin D status might lower the risk of RSV infection in offspring, according to Dutch researchers, who prospectively followed 156 neonates.

They found babies born with less than 50 nmol/L of vitamin D in cord blood had a sixfold increased risk of RSV-linked lower respiratory tract infection in the first year of life compared with those having levels of 75 nmol/L or higher.

Routine vitamin D screening in pregnant women was set for discussion at the Royal Australian and New Zealand College of Obstetricians and Gynaecologists’ women’s health committee meeting in late May, committee chair Dr Louise Farrell, said.
