Objectives: To assess the importance of the quality of response and of early relapse in unselected elderly patients with myeloma treated upfront with novel agents. Methods: We analyzed 135 unselected transplant‐ineligible patients older than 65 yr who were treated upfront with novel agent‐based regimens in a single center. Results: On intent to treat, 81% of patients achieved a response (28% sCR/CR, 23% VGPR, and 30% PR). Median progression‐free survival (PFS) for patients who achieved sCR/CR was 31 vs. 20 months for VGPR and 23 months for PR (P = 0.048). Median overall survival (OS) for patients with sCR/CR was 62 months, 53 months for VGPR and 38 months for patients with PR (P = 0.028). Early relapse (PFS < 12 months) was more common in patients with PR (39% vs. 21% for VGPR vs. 3% for sCR/CR). Patients who relapsed or progressed <12 months from initiation of treatment had a median OS of 15.4 months compared with 53 months (P < 0.001) for patients who had a PFS > 12 months despite the fact that after relapse or progression most patients were treated again with novel agents. In multivariate analysis, short PFS was the most significant adverse prognostic factor affecting OS, associated with a 7.25‐fold (P < 0.0001) increase in the risk of death. Conclusion: In newly diagnosed patients over 65 yr, treated upfront with novel agents achievement of CR and a PFS ≥12 months is associated with improved outcome. Patients who fail to respond or experience early relapse after primary therapy with novel agent‐based regimens should be encouraged to participate in clinical trials of novel agents and combinations. 相似文献

Introduction
The aim of this study was to investigate the kinetics of immunoglobulin M (IgM) during the different stages of sepsis.Methods
In this prospective multicenter study, blood sampling for IgM measurement was done within the first 24 hours from diagnosis in 332 critically ill patients; in 83 patients this was repeated upon progression to more severe stages. Among these 83 patients, 30 patients with severe sepsis progressed into shock and IgM was monitored daily for seven consecutive days. Peripheral blood mononuclear cells (PBMCs) were isolated from 55 patients and stimulated for IgM production.Results
Serum IgM was decreased in septic shock compared to patients with systemic inflammatory response syndrome (SIRS) and patients with severe sepsis. Paired comparisons at distinct time points of the sepsis course showed that IgM was decreased only when patients deteriorated from severe sepsis to septic shock. Serial measurements in these patients, beginning from the early start of vasopressors, showed that the distribution of IgM over time was significantly greater for survivors than for non-survivors. Production of IgM by PBMCs was significantly lower at all stages of sepsis compared with healthy controls.Conclusions
Specific changes of circulating IgM occur when patients with severe sepsis progress into septic shock. The distribution of IgM is lower among non-survivors. 相似文献13.

Bortezomib and lenalidomide are increasingly used in patients with AL amyloidosis, but long term data on their use as primary therapy in AL amyloidosis are lacking while early mortality remains significant. Thus, we analyzed the long term outcomes of 85 consecutive unselected patients, which received primary therapy with bortezomib or lenalidomide and we prospectively evaluated a risk adapted strategy based on bortezomib/dexamethasone to reduce early mortality. Twenty‐six patients received full‐dose bortezomib/dexamethasone, 36 patients lenalidomide with oral cyclophosphamide and low‐dose dexamethasone and 23 patients received bortezomib/dexamethasone at a dose and schedule adjusted to the risk of early death. On intent to treat, 67% of patients achieved a hematologic response (24% hemCRs) and 34% an organ response; both were more frequent with bortezomib. An early death occurred in 20%: in 36% of those treated with full‐dose bortezomib/dexamethasone, in 22% of lenalidomide‐treated patients but only in 4.5% of patients treated with risk‐adapted bortezomib/dexamethasone. Activity of full vs. adjusted dose bortezomib/dexamethasone was similar; twice weekly vs. weekly administration of bortezomib also had similar activity. After a median follow up of 57 months, median survival is 47 months and is similar for patients treated with bortezomib vs. lenalidomide‐based regimens. However, risk adjusted‐bortezomib/dexamethasone was associated with improved 1‐year survival vs. full‐dose bortezomib/dexamethasone or lenalidomide‐based therapy (81% vs. 56% vs. 53%, respectively). In conclusion, risk‐adapted bortezomib/dexamethasone may reduce early mortality and preserve activity while long term follow up indicates that remissions obtained with lenalidomide or bortezomib may be durable, even without consolidation with alkylators.Am.

Based on the controversial findings of clinical studies regarding the influence of multidrug resistance on mortality, 10 susceptible and 10 multidrug-resistant (MDR) and extended-spectrum beta-lactamase-producing isolates of Escherichia coli were applied to stimulate monocytes isolated from healthy donors. Immune mediators were estimated in supernatants. Four susceptible isolates (Group A) and four MDR isolates (Group B) were used to initiate acute pyelonephritis in 48 rabbits following inoculation of the pathogen into the right renal pelvis. Survival was recorded and blood monocytes were isolated and incubated to estimate the ex vivo release of tumour necrosis factor-alpha (TNFalpha). Release of TNFalpha, interleukin (IL)-6 and IL-8 was higher after 2 h and 4 h of stimulation by MDR isolates compared with susceptible isolates. The opposite occurred for the release of IL-12. Death occurred in 22 rabbits in Group A (91.7%) compared with 12 in Group B (50.0%) (P=0.003). Monocytes isolated at 24 h from Group A rabbits released significantly higher TNFalpha than monocytes from Group B. Tissue bacterial load after animal death was significantly higher in the kidneys of Group A rabbits. It is concluded that susceptible and MDR E. coli stimulate monocytes resulting in a different pattern of release of pro-inflammatory cytokines, which is accompanied by prolonged survival following experimental sepsis by MDR isolates. 相似文献
