It is approved in combination with dexamethasone as first-line therapy for transplant-ineligible patients with NDMM, and as maintenance treatment following autologous stem cell transplantation (ASCT). Although strong clinical trial evidence has supported the integration of lenalidomide into current treatment paradigms for NDMM, applying those paradigms to individual patients and determining which patients are most likely to benefit from lenalidomide treatment are more complex. In this paper, we utilize the available clinical trial evidence to provide recommendations for patient selection and lenalidomide dosing in both the first-line setting in patients ineligible for ASCT and the maintenance setting in patients who have undergone ASCT. In addition, we provide guidance on management of those adverse events that are most commonly associated with lenalidomide treatment, and consider the optimal selection and sequencing of next-line agents following long-term frontline or maintenance treatment with lenalidomide.}, language = {en} } @article{StengelVuralBrunderetal.2019, author = {Stengel, Helena and Vural, Atay and Brunder, Anna-Michelle and Heinius, Annika and Appeltshauser, Luise and Fiebig, Bianca and Giese, Florian and Dresel, Christian and Papagianni, Aikaterini and Birklein, Frank and Weis, Joachim and Huchtemann, Tessa and Schmidt, Christian and K{\"o}rtvelyessy, Peter and Villmann, Carmen and Meinl, Edgar and Sommer, Claudia and Leypoldt, Frank and Doppler, Kathrin}, title = {Anti-pan-neurofascin IgG3 as a marker of fulminant autoimmune neuropathy}, series = {Neurology: Neuroimmunology \& Neuroinflammation}, volume = {6}, journal = {Neurology: Neuroimmunology \& Neuroinflammation}, number = {5}, doi = {10.1212/NXI.0000000000000603}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-202462}, year = {2019}, abstract = {Objective To identify and characterize patients with autoantibodies against different neurofascin (NF) isoforms. Methods Screening of a large cohort of patient sera for anti-NF autoantibodies by ELISA and further characterization by cell-based assays, epitope mapping, and complement binding assays. Results Two different clinical phenotypes became apparent in this study: The well-known clinical picture of subacute-onset severe sensorimotor neuropathy with tremor that is known to be associated with IgG4 autoantibodies against the paranodal isoform NF-155 was found in 2 patients. The second phenotype with a dramatic course of disease with tetraplegia and almost locked-in syndrome was associated with IgG3 autoantibodies against nodal and paranodal isoforms of NF in 3 patients. The epitope against which these autoantibodies were directed in this second phenotype was the common Ig domain found in all 3 NF isoforms. In contrast, anti-NF-155 IgG4 were directed against the NF-155-specific Fn3Fn4 domain. The description of a second phenotype of anti-NF-associated neuropathy is in line with some case reports of similar patients that were published in the last year. Conclusions Our results indicate that anti-pan-NF-associated neuropathy differs from anti-NF-155-associated neuropathy, and epitope and subclass play a major role in the pathogenesis and severity of anti-NF-associated neuropathy and should be determined to correctly classify patients, also in respect to possible differences in therapeutic response.}, language = {en} } @article{ZlamyAlmanzarParsonetal.2016, author = {Zlamy, Manuela and Almanzar, Giovanni and Parson, Walther and Schmidt, Christian and Leierer, Johannes and Weinberger, Birgit and Jeller, Verena and Unsinn, Karin and Eyrich, Matthias and W{\"u}rzner, Reinhard and Prelog, Martina}, title = {Efforts of the human immune system to maintain the peripheral CD8+ T cell compartment after childhood thymectomy}, series = {Immunity \& Ageing}, volume = {13}, journal = {Immunity \& Ageing}, number = {3}, doi = {10.1186/s12979-016-0058-z}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-146497}, year = {2016}, abstract = {Background Homeostatic mechanisms to maintain the T cell compartment diversity indicate an ongoing process of thymic activity and peripheral T cell renewal during human life. These processes are expected to be accelerated after childhood thymectomy and by the influence of cytomegalovirus (CMV) inducing a prematurely aged immune system. The study aimed to investigate proportional changes and replicative history of CD8+ T cells, of recent thymic emigrants (RTEs) and CD103+ T cells (mostly gut-experienced) and the role of Interleukin-(IL)-7 and IL-7 receptor (CD127)-expressing T cells in thymectomized patients compared to young and old healthy controls. Results Decreased proportions of naive and CD31 + CD8+ T cells were demonstrated after thymectomy, with higher proliferative activity of CD127-expressing T cells and significantly shorter relative telomere lengths (RTLs) and lower T cell receptor excision circles (TRECs). Increased circulating CD103+ T cells and a skewed T cell receptor (TCR) repertoire were found after thymectomy similar to elderly persons. Naive T cells were influenced by age at thymectomy and further decreased by CMV. Conclusions After childhood thymectomy, the immune system demonstrated constant efforts of the peripheral CD8+ T cell compartment to maintain homeostasis. Supposedly it tries to fill the void of RTEs by peripheral T cell proliferation, by at least partly IL-7-mediated mechanisms and by proportional increase of circulating CD103+ T cells, reminiscent of immune aging in elderly. Although other findings were less significant compared to healthy elderly, early thymectomy demonstrated immunological alterations of CD8+ T cells which mimic features of premature immunosenescence in humans.}, language = {en} }
