D-dimer ELISA for biological control of low molecular weight heparin treatment during pregnancy

PREGNANCY, THROMBOPHILIA, LOW MOLECULAR WEIGHT HEPARIN, ELISA TESTAbstract
The condition of pregnant women with thrombophilia under low molecular weight heparin (HBPM) is special, there are few studies on D-dimer levels in patients cursing pregnancy with no complications.
This retrospective study aims at: a) to show expected levels of D-dimer Elisa in women cursing the first three months of pregnancy under HBPM treatment with no complications and successful pregnancy, and b) to show D-dimer Elisa as warning signs of obstetric complications.
The study included 113 women with proved trombophile and a risk obstetric history cursing pregnancy under HBPM treatment with no complications and successful pregnancy. They were all monthly controlled with D-dimer ELlSA.
Results showed that levels of D-dimer ELlSA significantly increased as pregnancy developed. Cut-points for the different "kit" are useful to assess hemostasis, especially during the second and third months when women under HBPM treatment reached those cut-points.
Median and 10 and 90 percentil were calculated for each react, different curves were considered in order to determine D-dimer levels during pregnancy under HBPM treatment.
A 90 percentil cut-point is suggested for each react. D-dimer ELlSA high levels might suggest the need of therapeutic measures to prevent obstetric complications as it is seen in four patients discussed in the paper.
