New clinical, laboratory and experimental insights, since the 1999 publication of the Sapporo preliminary classification criteria for antiphospholipid syndrome (APS), had been addressed at a workshop in Sydney, Australia, before the Eleventh International Congress on antiphospholipid antibodies. In this document, we appraise the existing evidence on(More)
OBJECTIVE To analyze the clinical and immunologic manifestations of antiphospholipid syndrome (APS) in a large cohort of patients and to define patterns of disease expression. METHODS The clinical and serologic features of APS (Sapporo preliminary criteria) in 1,000 patients from 13 European countries were analyzed using a computerized database. RESULTS(More)
The antiphospholipid syndrome--the association of venous and/or arterial thromboses, often accompanied by thrombocytopenia in the presence of the antiphospholipid antibodies ("lupus anticoagulant" antibodies to cardiolipin)--is seen mainly in patients with systemic lupus erythematosus (SLE) and the closely related "lupus-like" disease, i.e., lupus patients(More)
Twelve patients with chorea from a population of 500 patients with SLE and "lupus-like" disease were reviewed. Clinical histories, including time relationships of chorea to the systemic illness and other neurologic manifestations, are reported. Chorea appeared early in the course of disease in most patients, but the development of cerebral infarctions or(More)
Until recently, intravenous cyclophosphamide pulses with oral corticosteroids were regarded standard therapy for proliferative lupus nephritis (LN). Azathioprine, a less toxic alternative, was never proven to be inferior. In the first Dutch lupus nephritis study (enrollment between 1995 and 2001), we randomized 87 proliferative LN patients to either(More)
OBJECTIVE To determine whether the finding of antiphospholipid antibodies in patients with venous thromboembolic episodes should influence the duration of treatment with anticoagulant drugs by mouth. METHODS A retrospective study was carried out in 19 patients with antiphospholipid antibodies and a history of venous thromboembolic episodes. The median(More)
The objective of this work was to analyse the course of maternal disease and fetal outcome in pregnant patients with systemic lupus erythematosus (SLE) counselled and followed according to a protocol intended to optimize maternal and fetal outcome. The prospective study included all pregnancies between 1987 and 1993 in SLE patients known at least 6 months(More)
OBJECTIVE Fc gamma receptors of class IIa (Fc gamma RIIa) occur in 2 allelic forms, with either a low (IIa-R131) or a high (IIa-H131) affinity for complexed IgG2 and IgG3. This polymorphism might have implications for the handling of immune complexes. Therefore, we determined the distribution of the Fc gamma RIIa allotypes in patients with systemic lupus(More)
OBJECTIVES To identify the main causes of morbidity and mortality in patients with antiphospholipid syndrome (APS) during a 5-year period and to determine clinical and immunological parameters with prognostic significance. METHODS The clinical and immunological features of a cohort of 1000 patients with APS from 13 European countries who had been followed(More)
