Although not nearly as common in the geneticallyheterogeneous American population as in morehomogeneous European populations, factor V Leiden accountsfor about20% of diagnosesthat result fromhypercoagulabilityworkups.1Factor V Leidenis more commonamong Causasiansand is veryrare among personsof Africanor Asian descent.The managementof patientswho areheterozygous forfactor V Leidencontinues toevolve. The use of serial ultrasonography studies during early pregnancy have shown that the arterial signals in the yolk circulation disappear and the umbilicoplacental circulation increases between 8 and 10 weeks of gestation, indicating that the placenta replaces the yolk sac as an essential source of blood supply to the embryo at that time.1 Thus, it can be deduced that during the switch and at least from the beginning of the 11th week of gestation the maintenance of the permeability of the maternal placental intervillous space becomes a crucial necessity for the viability of the fetus. We looked for presumptive etiologic factors: hysterosalpingogram, karyotype in both parents, glucose tolerance test, toxoplasmosis serology, thyroid function, serum prolactin levels, normal luteal phase of at least 12 days and plasma progesterone above 25 ng/mL, absence of antinuclear factor, or antiphospholipid/antiprotein antibodies (lupus anticoagulant, anticardiolipin, anti2-glycoprotein I, antiannexin V, anti-phosphatidylethanolamine, immunoglobulin G [IgG], and IgM, by the methods previously described in our laboratory12,15), absence of antithrombin or protein C deficiency,11 fasting plasma total homocysteine lower than 15 M/L. Estimated gestational age was 12 weeks as measured from the patients last menstrual period, which was confirmed by a first trimester crown-rump length.

I have factor 5 Leiden as well and am only on baby aspirin. Low molecular weight heparin use was associated with a dramatic increase in the chance of giving birth to a living child, protein Z deficiency or antiprotein antibodies were independently associated with a significant decrease of this chance, and factor II G20210A mutation and protein S deficiency indicated a nonsignificant trend for a lower chance of good pregnancy outcome. I don't think the Dexane (dexamethasone# contributed much. I will definitely be getting a second opinion when I get back to Australia in a couple weeks!
