PURPOSE To determine the frequency, characteristics, and reversibility of peripheral neuropathy from bortezomib treatment of advanced multiple myeloma. PATIENTS AND METHODS Peripheral neuropathy was assessed in two phase II studies in 256 patients with relapsed and/or refractory myeloma treated with bortezomib 1.0 or 1.3 mg/m2 intravenous bolus on days 1,(More)
Dermatomyositis has been modeled as an autoimmune disease largely mediated by the adaptive immune system, including a local humorally mediated response with B and T helper cell muscle infiltration, antibody and complement-mediated injury of capillaries, and perifascicular atrophy of muscle fibers caused by ischemia. To further understand the pathophysiology(More)
Two studies recently identified a GGGGCC hexanucleotide repeat expansion in a non-coding region of the chromosome 9 open-reading frame 72 gene (C9ORF72) as the cause of chromosome 9p-linked amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD). In a cohort of 231 probands with ALS, we identified the C9ORF72 mutation in 17 familial (27.4%)(More)
PURPOSE To assess efficacy and safety of single-agent bortezomib in previously untreated patients with multiple myeloma, investigate prevalence of baseline and treatment-emergent polyneuropathy, and identify molecular markers associated with response and neuropathy. PATIENTS AND METHODS Patients received bortezomib 1.3 mg/m(2) on days 1, 4, 8, and 11, for(More)
Mutations in the fused in sarcoma (FUS) gene have recently been found to cause familial amyotrophic lateral sclerosis (FALS). We screened FUS in a cohort of 200 ALS patients [32 FALS and 168 sporadic ALS (SALS)]. In one FALS proband, we identified a mutation (p.R521C) that was also present in her affected daughter. Their clinical phenotype was remarkably(More)
In this study, we assess exome sequencing (ES) as a diagnostic alternative for genetically heterogeneous disorders. Because ES readily identified a previously reported homozygous mutation in the CAPN3 gene for an individual with an undiagnosed limb girdle muscular dystrophy, we evaluated ES as a generalizable clinical diagnostic tool by assessing the(More)
Sirs: Copper deficiency is a rare cause of anemia and neutropenia [4, 10–12, 14], and has been associated with a neurological syndrome in several case reports [1, 2, 5, 7–9]. Most cases of copper deficiency have been reported in patients with gastrointestinal disorders receiving long-term parenteral nutrition lacking in copper. Zinc excess has also been(More)
Peripheral nervous system (PNS) vasculitis and Guillain-Barré syndrome (GBS) are two distinct entities. Although there may be similarities in clinical presentation, the two are rarely confused. PNS vasculitis typically presents as a mononeuritis multiplex, as an overlapping mononeuritis multiplex, or as a distal symmetric sensorimotor polyneuropathy.(More)
