02/01/2010 - "To investigate the TFPI/protein S system in hereditary and acquired protein S deficiency. "
09/01/2013 - "Thus, although the acquired protein S deficiency in patients with cirrhosis is not associated with decreased TFPI levels, the TFPI/protein S anticoagulant system is functionally impaired."

07/01/2003 - "This is a rare case of combined anticardiolipin antibody positivity, acquired protein S deficiency, and Graves' disease."
07/01/2003 - "Graves' disease associated with anticardiolipin antibody positivity and acquired protein S deficiency."
07/01/1996 - "The presence of high titre anticentromere antibodies, anticardiolipin antibodies, protein S deficiency and supportive physical findings, suggested the diagnosis of concurrent antiphospholipid antibody syndrome (with secondary acquired protein S deficiency) and CREST syndrome. "

01/01/1997 - "We suggest that the thrombotic event is not related to antiphospholipid antibodies but to nephrotic syndrome and possibly to acquired protein S deficiency."
01/01/2004 - "As in our patient, an acquired protein S deficiency is probably responsible for most cases of purpura fulminans occurring after varicella, but the concomitant presence of antiphospholipid antibodies may also play a role."

03/01/1996 - "All children had a lupus anticoagulant and acquired protein S deficiency. "
03/01/1996 - "All children were found to have a lupus anticoagulant and acquired protein S deficiency. "
10/01/2000 - "Acquired protein S deficiency and lupus anticoagulant have been described in children with varicella who had purpura fulminans, disseminated intravascular coagulation or thrombosis. "
