• Study description:
  The aim of the study is to evaluate the safety to the mother and child of medications that are used by women suffering from SLE or MS during pregnancy using novel statistical methods. The ConcePTION platform will be used to analyse observational data from multinational cohort studies based on population based secondary data sources in Europe. The following studies will be undertaken: a. Identification of the most appropriate algorithm to identify MS and SLE in women of child bearing age and childhood infections in children in selected data sources on the ConcePTION platform. b. Evaluation of the utilisation trends and patterns of medications in women with SLE and MS (a) of childbearing age and (b) in pregnant women before, during and after pregnancy c. Evaluation of the safety to the mother and child of medications that are used by women suffering from SLE or MS during pregnancy. Analytic results from each data sources will be combined using novel meta-analytic techniques to overcome the issue of small numbers that will occur due to rare exposures and outcomes being studied. d. Evaluation of the increased risk of the occurrence of a major congenital malformation associated with first trimester exposure to medications that are used by women suffering from SLE or MS during pregnancy. EUROmediCAT data will be used to perform case-malformed analyses and to compile case series of congenital anomaly cases to identify possible safety indications.
