Patients with juvenile idiopathic arthritis who have been treated with disease-modifying antirheumatic drugs for years have no increased risk of adverse pregnancy outcomes, a study shows.

German researchers investigated the outcomes of 152 pregnancies in 98 women with juvenile idiopathic arthritis (JIA) and 39 pregnancies involving 21 fathers with JIA in one of few studies to include birth outcomes for men with the disease.

Most (61%) of patients had polyarticular-onset/-course JIA.

The average age at their first pregnancy was 24, and the mean duration of JIA was just under 14 years.
