Immune thrombocytopenia (ITP) is the most common autoimmune cytopenia. This disease often occurs in young women [1]. Pregnancy is a well-known risk factor for developing newly diagnosed ITP as well as for inducing disease flares in patients with chronic ITP [2]. Severe bleeding is rare but a therapeutic intervention is needed for one third of the pregnant patients, mostly before delivery to allow peridural analgesia [3,4]. However, the impact of pregnancy in women with an old history of ITP, considered as cured, has not been assessed.
