Abstract: Disclosed are methods and apparatuses for treating a pregnancy related hypertensive disorder, such as pre-eclampsia and eclampsia, using ex vivo treatment with an anti-sEng antibody bound to a solid support in order to reduce blood levels of sEng. The present invention provides a method of treating or preventing a disorder associated with soluble Endoglin (sEng), such as a pregnancy-related hypertensive disorder, in a subject in need thereof comprising providing ex vivo to the subject anti-sEng antibodies or sEng-binding fragments thereof in an amount sufficient and for a time sufficient to decrease the subject's blood levels of sEng to treat or prevent the disorder associated with sEng in the subject.

Abstract: Disclosed are methods and apparatuses for treating a pregnancy related hypertensive disorder, such as pre-eclampsia and eclampsia, using ex vivo treatment with an anti-sFlt-1 receptor (sFlt-1) antibody bound to a solid support in order to reduce blood levels of sFlt-1. Further disclosed are the sequences of the heavy chain and light chain CDRs of the anti-sFlt-1 antibodies.
