Abstract
Background
Rituximab is a novel therapy for immune thrombocytopenic purpura (ITP); however, information about its safety in pregnancy is limited. This case illustrates the successful use of rituximab to treat pregnancy-associated ITP.
Case
A 34-year-old woman presented with severe ITP at 23 weeks’ gestation. Standard treatment with corticosteroids, intravenous immune globulin, and splenectomy failed to raise the platelet count. Due to ongoing bleeding, rituximab was given in the 26th week of pregnancy. The platelet count rose to over 100 × 109/L after four weeks. The neonatal B-lymphocyte count normalized at four months after delivery. There were no neonatal complications of rituximab therapy.
Conclusion
Rituximab may be safe for use in treating pregnancy-associated ITP. This case highlights the need to investigate further the safety and efficacy of rituximab in pregnancy.
Résumé
Contexte
Le rituximab est un traitement novateur contre le purpura thrombocytopénique auto-immun (PTA); cependant, les données quant à son innocuité pendant la grossesse sont limitées. Le présent cas illustre l’utilisation réussie du rituximab pour la prise en charge du PTA associé à la grossesse.
Cas
Une femme de 34 ans présentait un PTA grave à 23 semaines de gestation. Le traitement standard au moyen de corticostéroïdes, d’immunoglobuline intraveineuse et d’une splénectomie n’était pas parvenu à donner lieu à une hausse de la numération plaquettaire. En raison de la poursuite des saignements, du rituximab lui a été administré au cours de la 26e semaine de grossesse. La numération plaquettaire est alors passée à plus de 100 × 109/l après quatre semaines. La numération de lymphocytes B néonatale s’est normalisée à quatre mois à la suite de l’accouchement. Le traitement au rituximab n’a occasionné aucune complication néonatale.
Conclusion
Le rituximab pourrait s’avérer sûr pour la prise en charge du PTA associé à la grossesse. Ce cas souligne la nécessité de procéder à d’autres études sur l’innocuité et l’efficacité du rituximab pendant la grossesse.
