What is that ALP
I think this antibodies are produce aganist the fetues?
if a female during pregent this ALP produced then she is aborted. second time she conceived the secondaey immune response will take place?.please answer the Question |
Actually, if a women with APLAS (Antiphospholipid
antibody syndrome) becomes pregnant the antibodies cause clot formation in the placental blood vessels and potentially in the fetal blood vessels leading to a miscarriage. The likelihood of this appears to remain the same in first and subsequent pregnancies.
Any woman who has two or more miscarriages in the late first to early second trimester with no other obvious causes, should be tested for APLAS as it is more common than generally thought.
It is an autoimmune disease and is classified as a subset of Systemic Lupus Erythematosus - as a result it is sometimes called Lupus Anticoagulant. One of the more common variants is labeled as Anticardiolipin. In all cases of APLAS the autoimmune antibodies bind to the various phospholipids which make up the cell membranes of the endothelial cells in the blood vessels. And, the exact identity of those phosphlipids varies between arteries and veins. As an aside; venous clot forming Lupus is more common then the arterial variety. The exact nature of the binding epitopes is not know to me but is likely to involve the proteins and saccharides on t he cell surface as well.
