Stromal cells in bone marrow play important roles in pro-inflammatory cytokine secretion causing fever following bortezomib administration in patients with multiple myeloma

Abstract: Bortezomib blocks the activation of nuclear factor-kappaB-mediated pro-inflammatory cytokines, however, systemic inflammatory symptoms following bortezomib administration have been reported, although their mechanisms remain elusive. Serum samples were obtained from five patients, who participated in a phase I/II study of Japanese patients with relapsed or refractory multiple myeloma (MM), and developed cyclic fever following bortezomib administration, to measure cytokine levels. Significant correlations betwee… Show more

“…As yet, there is no evidence that atypical NF-κB responses are involved in additional, bortezomib-related complications. However, despite its purported anti-inflammatory effects, bortezomib treatment has been reported to induce inflammatory symptoms, such as neuropathy and increases in serum levels of pro-inflammatory cytokines [2123]. In accordance with our findings, these symptoms suggest that proteasome inhibitors may serve to amplify rather than prevent inflammation.…”

“…For example, the proteasome inhibitor PS-341 (Velcade/bortezomib) is currently being used in the treatment of multiple myeloma, with the therapeutic benefit of bortezomib partly attributed to its ability to block NF-κB induction [19,20]. Paradoxically, many reports have described the development of inflammatory symptoms and increases in serum levels of pro-inflammatory cytokines following administration of bortezomib [2123]. As suggested recently, complications and resistance to bortezomib treatment may stem from NF-κB signaling induced by proteasome-independent mechanisms [24].…”

“…In contrast to the DAD type, the clinical characteristics of CLS‐like and hypoxia‐type BILD may respond better to corticosteroid therapy, lowering the mortality rate in these patients. For example, some investigators report that IL‐6 and IFN‐γ production cause pyrexia, and patients with severe hypoxia display high levels of CRP, IL‐6 and TNF‐α and elevated IL‐6 mRNA expression level due to proteasome inhibition, suggesting that corticosteroid therapy would be an effective treatment for these types of BILD .

“…Similar cytokines are also proposed to be the pathogenesis behind bortezomib induced lung injury [15]. Maruyama et al [16] suggest that the origin of cytokines in bortezomib-treated patient is from bone marrow stromal cells.…”
