“…Studies of corticosteroid use in pregnancy were confounded by multiple concomitant medications and use in high-risk pregnancies; particularly the fluorinated steroids, which are used to prevent or treat preterm labour and complications such as foetal lung immaturity. Therefore, we searched for further evidence on corticosteroids used to treat rheumatic disease and identified additional studies: 11 on prednisolone with ( n = 1218) pregnancies [ 31 , 71–80 ] and one on methylprednisolone with ( n = 12) pregnancies [ 81 ]. This evidence was combined with the previous studies: 47 on prednisolone ( n = 1503) [ 43 , 46 , 48 , 51–53 , 55 , 57 , 59–61 , 82–117 ]; 31 on dexamethasone ( n = 11 214) [ 48 , 54 , 88 , 97 , 118–144 ]; 27 on betamethasone ( n = 27 746) [ 118–120 , 125 , 126 , 128 , 130 , 131 , 140 , 143 , 145–162 ]; and 10 on general corticosteroid use ( n = 785) [ 42 , 49 , 50 , 54 , 163–168 ].…”
