Doug:

I'm assuming the diagnosis of LAC is based on those abnormal clotting studies after mixing with normal plasma.

Does your patient have any clinical features (not pregnancy related) that would support the diagnosis of antiphospholipid syndrome i.e., thrombosis, thrombocytopenia, livedo reticularis?

I would personally offer her the option of heparin therapy in addition to baby aspirin ( I prefer low molecular weight heparin, if her carrier will reimburse), though clearly her prior pregnancy outcome was favorable. I no longer offer steroids based on literature that suggests excessive risks of PTD.

Recent references of interest on antiphospholipid syndrome and pregnancy:

Best Wishes.

The American Medical Association is no longer designating CME hours for AMA Category II CME credit. However, physicians themselves may self designate learning activities as Category II CME credit hours if they feel it is of sufficient educational merit and meets the formal definitions of continuing medical education. OBGYN.net believes these interaction in this forum meets these criteria. For further information see the AMA web site.
