Offspring exposed to infliximab showed a trend toward increased risk of serious infections compared to infants exposed to other TNFi agents.
Acute bronchiolitis due to respiratory syncytial virus was the most common serious infection in all three groups, accounting for about one-third of all serious infections in each group. There were no cases of tuberculosis in exposed or unexposed RA offspring.
Although the findings could not confirm an increased risk of TNFi drugs overall, Dr. Vinet notes, “we could not exclude a differential risk according to specific TNFi characteristics, with infliximab potentially resulting in a three-fold increase in the risk of serious infections compared with other TNFis.”
