Case 1: a 53-year-old man was diagnosed with probable CAPS based on multiorgan thrombosis (pulmonary emboli, myocardial infarction, acute renal failure) and high levels of antiphospholipid antibody markers. Moreover, the patient fulfilled the SLE criteria. The symptoms developed after gastrointestinal infection. Case 2: a 48-year-old woman with long-term history of SLE and antiphospholipid syndrome, whose conditions worsened after gastrointestinal infection, was diagnosed with CAPS based on pulmonary microemboli, thrombosis of the portal vein, lower limb thrombophlebitis, and acute renal failure. Both the cases were treated with heparin, steroids in pulses, cyclophosphamide, and intravenous immunoglobulins, which resulted in subsidence of symptoms. %A Wielosz, Ewa %A Majdan, Maria %A Jeleniewicz, Radosław %A Biskup, Małgorzata %P 73-76 %9 journal article %R 10.5114/reum.2013.33399 %U http://dx.doi.org/10.5114/reum.2013.33399
