Demographic, clinical and antibody characteristics of patients with digital ulcers in systemic sclerosis: data from the DUO Registry

OBJECTIVES: The Digital Ulcers Outcome (DUO) Registry was designed to describe the clinical and antibody characteristics, disease course and outcomes of patients with digital ulcers associated with systemic sclerosis (SSc). METHODS: The DUO Registry is a European, prospective, multicentre, observational, registry of SSc patients with ongoing digital ulcer disease, irrespective of treatment regimen. Data collected included demographics, SSc duration, SSc subset, internal organ manifestations, autoantibodies, previous and ongoing interventions and complications related to digital ulcers. RESULTS: Up to 19 November 2010 a total of 2439 patients had enrolled into the registry. Most were classified as either limited cutaneous SSc (lcSSc; 52.2%) or diffuse cutaneous SSc (dcSSc; 36.9%). Digital ulcers developed earlier in patients with dcSSc compared with lcSSc. Almost all patients (95.7%) tested positive for antinuclear antibodies, 45.2% for anti-scleroderma-70 and 43.6% for anticentromere antibodies (ACA). The first digital ulcer in the anti-scleroderma-70-positive patient cohort occurred approximately 5 years earlier than the ACA-positive patient group. CONCLUSIONS: This study provides data from a large cohort of SSc patients with a history of digital ulcers. The early occurrence and high frequency of digital ulcer complications are especially seen in patients with dcSSc and/or anti-scleroderma-70 antibodies

Multidimensional analysis of clinical symptoms in patients with Fabry’s disease

International audienceAim:  Fabry’s disease is an X-linked inherited lysosomal storage disorder caused by the deficient activity of alpha-galactosidase A. The interrelationships between clinical symptoms in Fabry patients have not yet been fully established. Using cluster and multivariate analysis, the aim of the study was to determine the relationships among clinical symptoms and organ involvement, and predictive clinical symptoms for disease severity.Methods:  Clinical data obtained from 108 French Fabry patients were retrospectively collected and analysed using multiple correspondence analysis and hierachical ascendant classification. Multivariate analysis was also performed to determine among clinical symptoms predictors for cardiac disease (HRT), renal involvement (KDN) and brain complication (STR).Results:  The cohort comprised 41 male patients (aged 28.9 ± 11.6 years) and 67 female patients (aged 40.4 ± 15.5 years). Three main clusters of clinical symptoms could be delineated, characterising disease progression: the first cluster grouped digestive disorders (found in 30% of the patients) and exercise intolerance (32%), the second, cluster dyshidrosis (47%), acroparesthesia (67%), angiokeratoma (44%) and cornea verticillata (54%), the third, cluster grouped KDN (30%), HRT (39%) and STR (25%) and hearing loss (44%). In univariate analysis, the patient age predicted HRT and KDN, dyshidrosis predicted HRT and STR, angiokeratoma predicted KDN and cornea verticilla and hearing loss predicted KDN, HRT and STR. In multivariate analysis, hearing loss and age were independent predictors of organ complication.Conclusion:  Among the various interrelated clinical symptoms occurring in Fabry disease, patients with dyshidrosis and particularly hearing disorders appear to be at higher risk of organ complications
