Clinical Trial Summary

Walsdenström Macroglobulinemia (WM) is defined by a bone marrow lymphoplasmacytic infiltration and the presence of a monoclonal immunoglobulin M (IgM) in blood. Clinical manifestations of the hyperviscosity syndrome (HVS) are related to the large amount of IgM in circulating blood or to some physicochemical characteristics such as the presence of a cryoglobulin property. Although HVS is one of the most frequent criteria for initiating therapy in WM, few studies focused on its description and no diagnostic criteria are available.

The present study aims to identify a diagnostic system for HVS, taking into account objective symptoms such as bleedings, fundoscopic findings and also subjective symptoms such as fatigue and comorbidities that may influence the severity of symptoms.

Intervention

Other:
• fundoscopic picture
A central review of numerised fundoscopic picture will be performed.

Biological:
• blood sample
Two 10 ml blood vials will be sampled in addition to standard blood sampling for getting 6 to 7 200 µL aliquot. One 5 ml EDTA vial for GP1ba expression study, only if this sample can be sent to hemostasis laboratory within the 4 hours after sampling

Procedure:
• bone marrow sample
Five to 10 ml bone marrow sample will be collected in addition to standard bone marrow sampling for getting molecular characteristics of WM
