[When should consider antiphospholipid syndrome?]

In current practice, the occurrence of thrombosis--venous or arterial--is not rare. Moreover, during the follow-up of pregnancies, gynecologists often have to deal with fetal losses of their patients. Up to which point can these events be considered as "ordinary"? When and on which criteria can we consider an antiphospholipid syndrome? Efforts have been put these last years to better codify the diagnosis of this syndrome, so much on the laboratory side as on the clinical side. With a view to standardize these elements, a first consensus conference took place in 1999 in Sapporo, with an update in 2004 in Sydney, that has recently been published. The goal of these lines is to focus on new elements connected to the actual classification and on the resulting diagnosis elements, with the aim of obtaining a diagnosis of antiphospholipid syndrome in a rigorous way, and to initiate the appropriate treatment in different situations linked to this syndrome.
