Women with multiple sclerosis may have an increased risk of relapse in the months following in vitro fertilization (IVF), a French study showed.
The annualized relapse rate (ARR), or the number of relapses divided by the person-years at risk, was significantly higher during the 3-month period following IVF (mean ARR 1.60) compared with the 3 months just prior to the procedure (mean ARR 0.80) and a 3-month control period a year before the procedure (mean ARR 0.68), according to David-Axel Laplaud, MD, PhD, of the University of Nantes in France, and colleagues.
