Thrombotic thrombocytopenic purpura (TTP) during the course of HIV infection

Antiphospholipid antibodies and infections

Many infections have been found to be associated with antiphospholipid antibodies (aPL), although a pathogenic role for these antibodies has not usually been obvious except in a few isolated cases. Two types of aPL have been referred to as "autoimmune" and "infectious" types. This distinction, however, has subsequently been found not to be absolute.
