Despite the evidence of the immediate favorable outcome and safety of plasma-derived (pd)C1INH concentrate, there are no data regarding any difference among women who underwent or not pdC1INH during pregnancy or on children with\n                      <jats:italic>in utero<\/jats:italic>\n                      exposure to pdC1INH. The present interview study aimed at analyzing outcome of C1INH-HAE mothers and children according to pdC1INH-exposure during pregnancies.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>C1INH-HAE women who experienced at least 1 pregnancy were included from seven centers of the Italian Network for Hereditary and Acquired Angioedema (ITACA). The interview study retrospectively analyzed pregnancies who underwent (group 1) or not (group 2) pdC1INH. The overall goals of the study included immediate and long-term outcomes, in terms of outcomes in the time interval between pregnancy and survey.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      A total of 168 pregnancies from 87 included women were analyzed. At term delivery (&amp;gt;37 gestation-week, GW) has been registered in 73.8% of cases, while spontaneous abortion (SA) occurred in 14.2% of cases with a mean GW 7 \u00b1 2. The group 1 including pdC1INH-treated pregnancies comprised a third of the cohort (51\/168, time interval 1.5 \u00b1 10.4 yrs), while the group 2 represented 69.6% (117\/168, time interval 32.8 \u00b1 14 yrs). The same prevalence of SA occurred when comparing group 1 (11.7%) with group 2 (15.4%) with a similar GW at SA. The group 1 was older at the pregnancy time and younger at the interview than the group 2 (\n                      <jats:italic>P<\/jats:italic>\n                      &amp;lt; 0.01 for both); moreover, the group 1 showed a higher prevalence of cesarean delivery (\n                      <jats:italic>P<\/jats:italic>\n                      &amp;lt; 0.0001). The overall prevalence of obstetrical syndromes was similar between two groups: however, gestational diabetes was described only in pdC1INH-untreated pregnancies.\n                      <jats:italic>In utero<\/jats:italic>\n                      pdC1INH-exposed children (\n                      <jats:italic>n<\/jats:italic>\n                      = 45) did not show differences compared with unexposed ones (\n                      <jats:italic>n<\/jats:italic>\n                      = 99) in neonatal short-term outcomes.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Through appropriate management and counseling, most of C1INH-HAE women undergo successful pregnancy and delivery.
