الوصف: International audience; Familial forms of monoclonal gammopathy, defined as multiple myeloma (MM) or Monoclonal Gammopathy of Undetermined Significance (MGUS), are relatively infrequent and most series reported in the literature describe a limited number of families. MM rarely occurs in a familial context. MGUS is observed much more commonly, which can in some cases evolve toward full-blown MM. Although recurrent cytogenetic abnormalities have been described in tumor cells of sporadic cases of MM, the pathogenesis of familial MM remains largely unexplained. In order to identify genetic factors predisposing to familial monoclonal gammopathy, the Intergroupe Francophone du Myélome identified 318 families with at least two confirmed cases of monoclonal gammopathy. There were 169 families with parent/child pairs and 164 families with cases in at least two siblings, compatible with an autosomal transmission. These familial cases were compared with sporadic cases who were matched for age at diagnosis, sex and immunoglobulin isotype, with 10 sporadic cases for each familial case. The gender distribution, age and immunoglobulin subtypes of familial cases were unremarkable in comparison to sporadic cases. With a median follow-up of 7.4 years after diagnosis, the percentage of MGUS cases having evolved to MM was 3%. The median overall survival of the 148 familial MM cases was longer than that of matched sporadic cases, with projected values of 7.6 and 16.1 years in patients older and younger than 65 years, respectively. These data suggest that familial cases of monoclonal gammopathy are similar to sporadic cases in terms of clinical presentation and carry a better prognosis.

الوصف: Purpose: PET/MRI can provide simultaneous whole-body (WB) acquisition of T1,T2DIXON, Diffusion Weighted Images (DWI), Dynamic Contrast-Enhanced (DCE), and FDG-PET sequences. The objective of this study was to assess and compare the diagnostic performance of 4 combinations of these sequences for baseline staging of patients with monoclonal gammopathies (MG). Materials and methods: 104 patients with MG were included in this IRB approved study. Readers reviewed initial PET/MRIs for the presence of focal lesions (FL) and bone marrow infiltration (BMI) using 4 different image datasets: WB-MRI (including DWI), 3DT1-PET, WB-PET/MRI and WB-DCE-PET/MRI. A reference standard was established by a panel review of all baseline and follow-up imaging, biological and pathological data. The diagnostic performance for each image dataset to detect FL and BMI were evaluated and compared (Fisher’s exact test). Results: The sensitivity, specificity and accuracy for FL of WB-MRI was 87, 97 and 92%; of 3DT1-PET was 78, 97, and 95%; of WB-PET-MRI was 93, 97, and 95%; WB-DCE-PET-MRI was 93, 97, and 95%. The sensitivity of WB-PET-MRI and WB-DCE-PET-MRI were superior to 3DT1-PET (p=0,036) without decreasing specificity. The sensitivity, specificity and accuracy of WB-MRI for BMI was 91, 80 and 85% ; of 3DT1-PET was 53, 89, and 74% ; of WB-PET-MRI was 98, 66, and 79% ; of WB-DCE-PET-MRI was 98, 59, and 75%. 3DT1-PET lacked sensitivity compared to all other datasets (p<0.0001). WB-MRI had better sensitivity than 3DT1-PET (p<0.001) and specificity than DCE-PET/MRI (p<0.001). Conclusion: PET/MRI should combine both WB bone marrow dedicated MRI and FDG PET images with no added value of DCE for baseline staging. ; L’objectif de cette étude était d'évaluer et de comparer les performances diagnostiques de 4 combinaisons de séquences en TEP/IRM pour le bilan initial des patients atteints de gammapathies monoclonales (GM).

الوصف: International audience ; We have recently described a new form of light chain deposition disease (LCDD) presenting as a severe cystic lung disorder requiring lung transplantation. There was no bone marrow plasma cell proliferation. Because of the absence of disease recurrence after bilateral lung transplantation and of serum-free light chain ratio normalization after the procedure, we hypothesized that monoclonal light chain synthesis occurred within the lung. The aim of this study was to look for the monoclonal B-cell component in 3 patients with cystic lung LCDD. Histologic examination of the explanted lungs showed diffuse nonamyloid kappa light chain deposits associated with a mild lymphoid infiltrate composed of aggregates of small CD20(+), CD5(-), CD10(-) B lymphocytes reminiscent of bronchus-associated lymphoid tissue. Using polymerase chain reaction (PCR), we identified a dominant B-cell clone in the lung in the 3 studied patients. The clonal expansion of each patient shared an unmutated antigen receptor variable region sequence characterized by the use of IGHV4-34 and IGKV1 subgroups with heavy and light chain CDR3 sequences of more than 80% amino acid identity, a feature evocative of an antigen-driven process. Combined with clinical and biologic data, our results strongly argue for a new antigen-driven primary pulmonary lymphoproliferative disorder.

الوصف: International audience ; Beta-blockers are widely prescribed in elderly patients and may induce severe adverse drug reactions. We report a case of bisoprolol-induced bradycardia in an elderly patient with impaired renal function and use of cytochrome P450 inhibitors. A literature review has been performed in order to analyze pharmacokinetic risk factors of beta-blockers overdosing in geriatrics. Various mechanisms can result in decreased elimination of beta-blockers. These mechanisms vary according to the beta-blocker agent and may be combined in some individuals, especially elderly patients. This can lead to unexpected overexposure. Knowledge about drug interactions and pharmacokinetic elimination pathways is important for preventing overexposure and adverse drug reactions when using beta-blockers.

الوصف: International audience ; Monoclonal gammopathies are frequently complicated by kidney lesions that increase the disease morbidity and mortality. In particular, abnormal Ig free light chains (LCs) may accumulate within epithelial cells, causing proximal tubule (PT) dysfunction and renal Fanconi syndrome (RFS). To investigate the mechanisms linking LC accumulation and PT dysfunction, we used transgenic mice overexpressing human control or RFS-associated κ LCs (RFS- κ LCs) and primary cultures of mouse PT cells exposed to low doses of corresponding human κ LCs (25 μ g/ml). Before the onset of renal failure, mice overexpressing RFS- κ LCs showed PT dysfunction related to loss of apical transporters and receptors and increased PT cell proliferation rates associated with lysosomal accumulation of κ LCs. Exposure of PT cells to RFS- κ LCs resulted in κ LC accumulation within enlarged and dysfunctional lysosomes, alteration of cellular dynamics, defective proteolysis and hydrolase maturation, and impaired lysosomal acidification. These changes were specific to the RFS- κ LC variable (V) sequence, because they did not occur with control LCs or the same RFS- κ LC carrying a single substitution (Ala30→Ser) in the V domain. The lysosomal alterations induced by RFS- κ LCs were reflected in increased cell proliferation, decreased apical expression of endocytic receptors, and defective endocytosis. These results reveal that specific κ LCs accumulate within lysosomes, altering lysosome dynamics and proteolytic function through defective acidification, thereby causing dedifferentiation and loss of reabsorptive capacity of PT cells. The characterization of these early events, which are similar to those encountered in congenital lysosomal disorders, provides a basis for the reported differential LC toxicity and new perspectives on LC-induced RFS.

الوصف: International audience; PURPOSE OF REVIEW: Immune-mediated neuropathies are increasingly recognized as potential causes of disability. Their diagnostic criteria and management options are still a matter of debate. This review focuses on recent findings in the diagnostic and therapeutic management of these disorders and on their prognostic factors. RECENT FINDINGS: The more widespread use of consensus criteria has improved diagnostic strategies for immune-mediated neuropathies. Studies of large prospective series have defined the spectrum of these disorders and their respective prognoses. Although treatment of these disorders mostly relies on corticosteroids and intravenous immunoglobulin, recent controlled trials have indicated the value of targeted immunotherapies. The further development of these therapies requires better understanding of the pathophysiology of these disorders. Immunological and immunopathological studies have improved our understanding of immune-mediated neuropathies over the last few years. SUMMARY: Identifying immune-mediated neuropathies is important, as these disorders are treatable. Diagnostic strategies have improved our capacity to recognize affected patients who can be offered effective treatments. Therapeutic options for immune-mediated neuropathies are still rather limited, although targeted immunotherapies may improve the prognosis of these disorders in the near future.

الوصف: International audience; Immune-mediated neuropathies are treatable disorders that can result in considerable disability in some cases. Chronic immune-mediated neuropathies include chronic inflammatory demyelinating polyradiculoneuropathy, multifocal motor neuropathy and neuropathy associated with monoclonal gammopathy. In recent years, therapeutic strategies for these disorders have become clearer as a result of large, randomized controlled trials. However, the treatments used can have serious adverse effects and at least 30% of patients do not respond to conventional therapies. The aim of this paper is to review available data on evidence-based immunotherapy of chronic immune-mediated neuropathies and to summarize recent findings and results obtained with new innovative therapies, such as new immunosuppressants and monoclonal antibodies.

الوصف: We have recently described a new form of light chain deposition disease (LCDD) presenting as a severe cystic lung disorder requiring lung transplantation. There was no bone marrow plasma cell proliferation. Because of the absence of disease recurrence after bilateral lung transplantation and of serum-free light chain ratio normalization after the procedure, we hypothesized that monoclonal light chain synthesis occurred within the lung. The aim of this study was to look for the monoclonal B-cell component in 3 patients with cystic lung LCDD. Histologic examination of the explanted lungs showed diffuse nonamyloid κ light chain deposits associated with a mild lymphoid infiltrate composed of aggregates of small CD20+, CD5−, CD10− B lymphocytes reminiscent of bronchus-associated lymphoid tissue. Using polymerase chain reaction (PCR), we identified a dominant B-cell clone in the lung in the 3 studied patients. The clonal expansion of each patient shared an unmutated antigen receptor variable region sequence characterized by the use of IGHV4-34 and IGKV1 subgroups with heavy and light chain CDR3 sequences of more than 80% amino acid identity, a feature evocative of an antigen-driven process. Combined with clinical and biologic data, our results strongly argue for a new antigen-driven primary pulmonary lymphoproliferative disorder.
