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. The cohort consisted of 820 female patients (82.0%) and 180 male patients (18.0%) with a mean ؎ SD age of 42 ؎ 14 years at study entry. "Primary" APS was present in 53.1% of the patients; APS was associated with systemic lupus erythematosus (SLE) in 36.2%, with lupus-like syndrome in 5.0%, and with other diseases in 5.9%. A variety of thrombotic manifestations affecting the majority of organs were recorded. A catastrophic APS occurred in 0.8% of the patients. Patients with APS associated with SLE had more episodes of arthritis and livedo reticularis, and more frequently exhibited thrombocytopenia and leukopenia. Female patients had a higher frequency of arthritis, livedo reticularis, and migraine. Male patients had a higher frequency of myocardial infarction, epilepsy, and arterial thrombosis in the lower legs and feet. In 28 patients (2.8%), disease onset occurred before age 15; these patients had more episodes of chorea and jugular vein thrombosis than the remaining patients. In 127 patients (12.7%), disease onset occurred after age 50; most of these patients were men. These patients had a

ObjectivesTo assess the prevalence of the main causes of morbi-mortality in the antiphospholipid syndrome (APS) during a 10-year-follow-up period and to compare the frequency of early manifestations with those that appeared later.MethodsIn 1999, we started an observational study of 1000 APS patients from 13 European countries. All had medical histories documented when entered into the study and were followed prospectively during the ensuing 10 years.Results53.1% of the patients had primary APS, 36.2% had APS associated with systemic lupus erythematosus and 10.7% APS associated with other diseases. Thrombotic events appeared in 166 (16.6%) patients during the first 5-year period and in 115 (14.4%) during the second 5-year period. The most common events were strokes, transient ischaemic attacks, deep vein thromboses and pulmonary embolism. 127 (15.5%) women became pregnant (188 pregnancies) and 72.9% of pregnancies succeeded in having one or more live births. The most common obstetric complication was early pregnancy loss (16.5% of the pregnancies). Intrauterine growth restriction (26.3% of the total live births) and prematurity (48.2%) were the most frequent fetal morbidities. 93 (9.3%) patients died and the most frequent causes of death were severe thrombosis (36.5%) and infections (26.9%). Nine (0.9%) cases of catastrophic APS occurred and 5 (55.6%) of them died. The survival probability at 10 years was 90.7%.ConclusionsPatients with APS still develop significant morbidity and mortality despite current treatment. It is imperative to increase the efforts in determining optimal prognostic markers and therapeutic measures to prevent these complications.

Objective. To estimate the incidence rates of serious and nonserious infections in patients with rheumatoid arthritis (RA) who start treatment with a biologic agent, and to compare these rates with those in patients with RA who receive conventional treatment.Methods. Patients enrolled in the German biologics register between May 2001 and September 2003 were included. Treating rheumatologists assessed adverse events and serious adverse events. All adverse events and serious adverse events experienced within 12 months after study entry were analyzed. Propensity score methods were applied to estimate which part of a rate increase was likely to be attributable to differences in patient characteristics.Results. Data were available for 512 patients receiving etanercept, 346 patients receiving infliximab, 70 patients receiving anakinra, and 601 control patients treated with disease-modifying antirheumatic drugs.The total number of adverse events per 100 patientyears was 22.6 (95% confidence interval [95% CI] 18.7-27.2) among patients receiving etanercept, 28.3 (95% CI 23.1-34.7) among patients receiving infliximab, and 6.8 (95% CI 5.0-9.4) among controls (P < 0.0001). Significant differences in the rate of serious adverse events were also observed. For patients receiving etanercept, those receiving infliximab, and controls, the total numbers of serious adverse events per 100 patient-years were 6.4 (95% CI 4.5-9.1), 6.2 (95% CI 4.0-9.5), and 2.3 (95% CI 1.3-3.9), respectively (P ‫؍‬ 0.0016). After adjusting for differences in the case patient mix, the relative risks of serious adverse events were 2.2 (95% CI 0.9-5.4) for patients receiving etanercept and 2.1 (95% CI 0.8-5.5) for patients receiving infliximab, compared with controls.Conclusion. Patients treated with biologic agents have a higher a priori risk of infection. However, our data suggest that this risk is increased by treatment with tumor necrosis factor inhibitors.

There are characteristic signs of temporal arteritis that can be visualized by color duplex ultrasonography. The most specific sign is a dark halo, which may be due to edema of the artery wall. In patients with typical clinical signs and a halo on ultrasonography, it may be possible to make a diagnosis of temporal arteritis and begin treatment without performing a temporal-artery biopsy.

The associations found are in agreement with biological mechanisms and clinical observations. As there is a paucity of real-life data on adverse effects of glucocorticoids prescribed to unselected groups of patients, these data may help the clinician to adapt therapy with glucocorticoids accordingly and improve the benefit-risk ratio.
