Voormolen DN, et al. - Researchers performed a nationwide multicentre, open label, randomized, controlled trial to examine the effectiveness of the additional use of retrospective continuous glucose monitoring (CGM) in diabetic pregnancies. They randomized 300 pregnant women with type 1, type 2 or with gestational diabetes to either CGM or standard treatment between July 2011 and September 2015. The present data indicated that use of intermittent retrospective CGM did not lessen the risk of macrosomia in diabetic pregnancy. They suggested that CGM provides detailed information concerning glycaemic fluctuations, however, as a treatment strategy did not translate into improved pregnancy outcome.
