Key clinical point: Psoriatic arthritis and ankylosing spondylitis increased the risk of certain adverse pregnancy outcomes, although outcomes were generally favorable overall.

Major finding: Compared with healthier women, those with psoriatic arthritis had an 81% increased risk for moderate preterm delivery (32-36 weeks’ gestation), among other adverse obstetric outcomes, while women with ankylosing spondylitis had a 67% increased risk of infant hospitalization in the neonatal intensive care unit.
