Active clinical trials for "Paraproteinemias"

Pruritus is most often secondary to dermatitis but can also occur without skin lesions, it is called pruritus sine materia. The causes of pruritus sine materia are various: haematological (myeloproliferative neoplasia ...), hepatic (cholestasis ...), renal (chronic renal failure, dialysis), endocrine (iron deficiency ...), secondary to drug intake ... or idiopathic when no cause is found. Gammapathies are among the causes of pruritus sine materia, and as such electrophoresis of serum proteins is usually part of the pruritus assessment to look for monoclonal gammopathy (MGUS, multiple myeloma, Waldenström disease). However, there is very little data on the frequency of pruritus in patients with monoclonal gammopathy and the characteristics of this pruritus. So the aim of this study is to compare the frequency of pruritus between patients with monoclonal gammapathy and controls

The purpose of this study is to examine how patients with multiple myeloma (MM) have been impacted by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic. The study will use a questionnaire to further understand how patients are being affected and gather information in order to track the long-term effects of the coronavirus. The scope of the questionnaire will include, COVID-19 diagnosis and treatment, changes in myeloma treatment and care, clinical trial familiarity, health and fitness, and quality of life. This questionnaire is a follow-on to the "MM and COVID-19" questionnaire.

This is a study to investigate the functional consequences of paraprotein production in MGUS (Monoclonal Gammopathy of Unknown Significance).

Patients with newly diagnosed symptomatic multiple myeloma per IMWG criteria prior to therapy initiation are enrolled in the study. The aim of the study is to investigate clinical and disease related risk factors for venous thromboembolism (VTE) in these patients as well as possible biomarkers of hypercoagulability linked with the occurrence of venous thromboembolism at diagnosis and during the disease course. The purpose is to create a risk assessment model for VTE in newly diagnosed multiple myeloma patients and make the model more accurate by combining relevant clinical and disease characteristics with biomarkers of cellular and plasma hypercoagulability. A standardized clinical research form is completed for all patients at baseline, 3, 6 and 12 month follow up to include relevant clinical, patient-related, disease-related and treatment related data. Blood sampling also takes place at baseline and 3,6,12 months to assess multiple biomarkers of plasma and cellular hypercoagulability. In addition lowe limb ultrasound is performed at baseline, 6 and 12 months. The primary endpoint is VTE occurrence. Following the elaboration of the ROADMAP-CAT-MM risk assessment model we will prospectively validate it. We expect that patients who are classified, as high risk according to the ROADMAP-CAT-MM will experience symptomatic VTE more frequently and will have higher morbidity and mortality rates during the follow-up. The prospective validation of the ROADMAP-CAT-MM will provide guidance for the use and choice of thromboprophylaxis in these patients and will identify high risk patients eligible for thromboprophylaxis with low molecular weight heparin (tinzaparin). In addition to symptomatic patients with multiple myeloma the study aims to investigate VTE risk in all plasma cell dyscrasias and will recruit patients with monoclonal gammopathy of undetermined significance, asymptomatic multiple myeloma, primary amyloidosis and Waldenström's macroglobulinemia.

Cardiac amyloidosis describes a process by which abnormally folded proteins infiltrate the heart tissue. Given the insidious nature of this disease process, diagnosis is often too late for a meaningful intervention. Advances in the treatment of the amyloidoses have improved outcomes for patients with these conditions. The focus of this study is to identify the involvement of the heart, most closely associated with mortality, so that aggressive management can be instituted improving prognosis.

The purpose of this study is to determine whether the monoclonal protein in patients with tuberculosis and monoclonal gammopathy has anti-tuberculous activity, and whether genes coding their monoclonal proteins show characteristic mutations.

This is the first prospective study which evaluate patients with small B-cell clones to diagnose monoclonal gammopathy of renal significance (MGRS) and characterize it clinically, anatomopathologically and pathophysiologically taking int account a geriatric approach.
