Identifying diagnostic criteria for hyperviscosity syndrome in Waldenström Macroglobulinemia

Clinical Study of the Hyperviscosity Syndrome in Waldenström Macroglobulinemia

Not applicable Interventional Centre Hospitalier Universitaire, Amiens · NCT04898647

This study is trying to create better guidelines to diagnose hyperviscosity syndrome in people with Waldenström Macroglobulinemia by looking at both their symptoms and test results.

What this trial studies

This clinical study focuses on patients with Waldenström Macroglobulinemia (WM) to develop a diagnostic system for hyperviscosity syndrome (HVS). It aims to evaluate both objective symptoms, such as bleeding and fundoscopic findings, and subjective symptoms like fatigue and comorbidities that may affect symptom severity. Patients will undergo assessments including fundoscopic pictures, blood samples, and bone marrow samples to gather comprehensive data. The study seeks to establish clearer diagnostic criteria for HVS, which is often a reason for initiating therapy in WM patients.

Who should consider this trial

Good fit: Ideal candidates for this study are patients diagnosed with Waldenström Macroglobulinemia who may require treatment initiation due to hyperviscosity.

Not a fit: Patients with other chronic B-cell malignancies or those with histologic transformation of WM may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved diagnostic criteria for hyperviscosity syndrome, enhancing treatment decisions for patients with Waldenström Macroglobulinemia.

How similar studies have performed: While there is limited research specifically on hyperviscosity syndrome in WM, the study aims to fill a gap in existing literature, suggesting a novel approach.
