title: Bernard Soulier syndrome in pregnancy: a systematic review.
abstract: Bernard Soulier syndrome (BSS) is a rare disorder of platelets, inherited mainly as an autosomal recessive trait. It is characterised by qualitative and quantitative defects of the platelet membrane glycoprotein (GP) Ib-IX-V complex. The main clinical characteristics are thrombocytopenia, prolonged bleeding time and the presence of giant platelets. Data on the clinical course and outcome of pregnancy in women with Bernard Soulier syndrome is scattered in individual case reports. In this paper, we performed a systematic review of literature and identified 16 relevant articles; all case reports that included 30 pregnancies among 18 women. Primary postpartum haemorrhage was reported in 10 (33%) and secondary in 12 (40%) of pregnancies, requiring blood transfusion in 15 pregnancies. Two women had an emergency obstetric hysterectomy. Alloimmune thrombocytopenia was reported in 6 neonates, with one intrauterine death and one neonatal death. Bernard Soulier syndrome in pregnancy is associated with a high risk of serious bleeding for the mother and the neonate. A multidisciplinary team approach and individualised management plan for such women are required to minimise these risks. An international registry is recommended to obtain further knowledge in managing women with this rare disorder.
