U. Picillo et al., ASSOCIATION OF PRIMARY ANTIPHOSPHOLIPID SYNDROME WITH INHERITED ACTIVATED PROTEIN-C RESISTANCE, Journal of rheumatology, 25(6), 1998, pp. 1232-1234
A 65-year-old man had had arterial thromboses of the lower limbs and c
erebral region for several years; tests revealed anticardiolipin, anti
phosphatidylserine, anti-beta(2)-glycoprotein I antibodies, and lupus
anticoagulant, As well, both phenotypic and genotypic resistance to ac
tivated protein C was found. Antiphospholipid antibodies have been rep
orted to interfere in different ways with the functions of protein C;
in our patient the simultaneous existence of inherited resistance to a
ctivated protein C could account for the thrombophilic status underlyi
ng the diffuse and serious arterial thromboses.
