The strategy comprised weekly surveillance of platelet count during pregnancy (and quarterly monitoring of ADAMTS13 activity) for women with immune thrombotic thrombocytopenic purpura, without any routine prophylactic treatment. In case of thrombocytopenia < 150,000/mm3 (with or without hemolysis relapse), women with hereditary thrombotic thrombocytopenic purpura systematically received plasma infusions twice weekly until platelet count normalized.ResultsA total of 13 patients were included (7 with hereditary thrombotic thrombocytopenic purpura and 6 with immune thrombotic thrombocytopenic purpura, with 20 planned pregnancies (11 and 9, respectively). All pregnancies resulted in live births, and all mothers survived. There was a marked improvement in pregnancy terms in the hereditary thrombotic thrombocytopenic purpura group compared to index pregnancies (37 [35;39] versus 31 [24;38] weeks, p = 0.037) and birth weights (3265 [3029;3410] versus 2160 [1240;2705] grams, p = 0.016), with need for plasma support mostly starting during the third trimester (5/7 patients, 7/11 pregnancies). A single hereditary thrombotic thrombocytopenic purpura relapse occurred, with rapid resolution after plasma support intensification. There were no relapses in the immune thrombotic thrombocytopenic purpura group, with ADAMTS13 activity systematically above 40% during all monitored pregnancies.ConclusionThese real-life data support the feasibility of a preemptive approach to pregnancy monitoring in women with known thrombotic thrombocytopenic purpura who undergo active surveillance within a multidisciplinary network.Lire moins >
