OBJECTIVE: To evaluate the therapeutic effect and adverse reactions of the maintenance therapies with Thalidomine or Bortezomib in the patients with newly diagnosed multiple myeloma (MM), so as to provide a reference for clinical treatment. METHODS: A retrospective analysis was conducted to compare the progression-free survival (PFS), overall survival (OS) and adverse reaction rate of 23 MM patients received the maintenance therapies of Bortezomib and of 68 MM patients received maintenance therapy of Thalidomine. RESULTS: The maintenance therapy with Bortezomib could extend the PFS of MM patients as compared with Thalidomine (PFS rate of patients on the maintenance therapy of Bortezomib in 12th, and 24th month was 100%, 88.89%, and that of Thalidomine-treated group was 72.31%, 47.54%). What's more, some specific patients could get better 2-year PFS rate in Bortezomib group than that in Thalidomine group, such as older than 65 years old, after autologous hematopoietic stem cell transplantation(ASCT), having genetic changes, extramedullary lesions, poor renal function, low serum free light chain ratio, high β2-MG, anemia, high LDH, VGPR of induction and consolidation therapy. The OS rate of Bortezomib on 18th, 24th and 30th month was 100%, 88.89%, 80% verus 91.52%,83.63%,72.90% of the group with thalidemide at the same time. As for 2-year OS rate, the Bortezomib group was higher than Thalidomine without statistical differences. However, the patients such as older than 65 years old, poor renal function and with extramedullary lesions, would also get higher 2-year OS rate from Bortezomi. Bortezomib and thalidomide could cause bone marrow suppression, peripheral neuritis and other adverse reactions. CONCLUSION The efficacy of maintenance therapy with Bortezomib is superior to thalidomide. As a conclusion, bortezomib is a better option for maintenance therapy of MM patient.

PURPOSE: Recently, bortezomib has been used to treat antibody-mediated rejection (AMR) refractory to conventional treatment such as plasmapheresis, intravenous immunoglobulin, and rituximab. The authors aimed to describe their experiences when bortezomib was used to treat refractory AMR. MATERIALS AND METHODS: Eleven refractory AMR episodes treated with bortezomib were included in this study. The patients received one or two cycles of bortezomib (1.3 mg/m2) on days 1, 4, 8, and 11. RESULTS: Bortezomib effectively reduced antibodies against various targets, including human leukocyte antigen (HLA) class I and II, ABO blood group antigen, and angiotensin II type 1 receptor. Antibodies were depleted or reduced significantly in eight AMR episodes. Overall, there was a significant improvement in the mean estimated glomerular filtration rate (eGFR) at 3 months after therapy (36.91+/-22.15 mL/min/1.73 m2) versus eGFR at time of AMR diagnosis (17.00+/-9.25 mL/min/1.73 m2; p=0.007). All six early-onset AMR episodes (within 6 months post-transplantation) showed full recovery of allograft function. Additionally, three of the five late-onset AMR episodes (>6 months post-transplantation) showed improved allograft function. CONCLUSION: Anti-humoral treatment based on bortezomib might be an effective strategy against refractory AMR caused by various types of antibodies. Notably, this treatment could be more effective in early-onset AMR than in late-onset AMR.

PURPOSE: Although the proteasome inhibitor known as bortezomib can modulate the inflammatory process through the nuclear factor-kappa B signaling pathway, the immunomodulatory effect of pre-incubated bortezomib has not been fully evaluated for inflammation by infectious agents. Therefore, we evaluated the effect of bortezomib on the expression of inflammatory cytokines and mediators in macrophage cell lines and on survival in a murine peritonitis sepsis model. MATERIALS AND METHODS: Bortezomib was applied 1 hr before lipopolysaccharide (LPS) stimulation in RAW 264.7 cells. The cecal ligation and puncture (CLP) experiments were performed in C57BL/6J mice. RESULTS: Pre-incubation with bortezomib (25 nM or 50 nM) prior to LPS (50 ng/mL or 100 ng/mL) stimulation significantly recovered the number of viable RAW 264.7 cells compared to those samples without pre-incubation. Bortezomib decreased various inflammatory cytokines as well as nitric oxide production in LPS-stimulated cells. The 7-day survival rate in mice that had received bortezomib at 0.01 mg/kg concentration 1 hr prior to CLP was significantly higher than in the mice that had only received a normal saline solution of 1 mL 1 hr prior to CLP. In addition, the administration of bortezomib at 0.01 mg/kg concentration 1 hr before CLP resulted in a significant decrease in inflammation of the lung parenchyma. Collectively, pretreatment with bortezomib showed an increase in the survival rate and changes in the levels of inflammatory mediators. CONCLUSION: These results support the possibility of pretreatment with bortezomib as a new therapeutic target for the treatment of overwhelming inflammation, which is a characteristic of severe sepsis.

This study was aimed to evaluate the clinical characteristics of immunoglobin D multiple myeloma (IgD MM) and its curative efficacy. The clinical data of 15 cases of newly diagnosed IgD MM from April 1993 to June 2013 were analyzed retrospectively. Among 15 cases received induction treatment, the traditional chemotherapy was carried out in 9 cases, bortezomib-based therapy was performed in 6 cases. The diagnostic criteria and disease response criteria of MM were based on International Myeloma Working Group (IMWG) criteria,survival time was analyzed by using Kaplan-Meier method, the median age of patients was 57 years (range 40-72), the ratio of male to female was 2:1, the MM patients in Durie-Salmon stage III accounted for 100% (15/15) , the MM patients with λ light chain accounts for 80% (12/15) , with bone lesion 86.7% (13/15), with pleural effusion 26.7% (4/15) , with renal impairment (RI) 86.7% (13/15) ,with anemia 93.3% (14/15) , with serum album<35 g/L 26.7% (4/15). The median creatinine clearance rate (Ccr) of patients was 23.1 (6-44) ml/min, and median hemoglobin level was 82 (43-131) g/L. The results showed that in followed-up 11 cases, 8 cases died, 3 cases survived; the average duration of follow-up for these cases was 20 (0.5-138) months, the median progression-free survival time (PFS) was 7 (95%CI4.6-9.4) months, and the median overall survival (OS) time was 15 (95%CI6.6-27.4 ) months. Compared traditional chemotherapy with bortezomib regimen therapy,median OS time was 17 (95%CI6.1-28.0) months vs 15 (95%CI 0.0-33.3) months (P = 0.90) . Assessable curative effect of 14 cases was as follows: CR 33.3% (5/15); VGPR 13.3% (2/15); PR 20% (3/15); SD 20% (3/15); PD 6.7% (1/15). It is concluded that IgD MM is a rare type of MM and has a poor prognosis. Bortezomib may be beneficial for some patients with extramedullary infiltration. Autologous hematopoietic stem cell transplantation may improve survival time.

BACKGROUNDSignificant efforts have been made to identify factors that differentiate patients treated with novel therapies, such as bortezomib in multiple myeloma (MM). The exact expression pattern and prognostic value of the cancer/testis antigen preferentially expressed antigen of melanoma (PRAME) in MM are unknown and were explored in this study.

METHODSThe transcript level of PRAME was detected in bone marrow specimens from 100 newly diagnosed MM patients using real-time quantitative polymerase chain reaction, and the prognostic value of PRAME was determined through retrospective survival analysis. PRAME expression higher than the upper limit of normal bone marrow was defined as PRAME overexpression or PRAME (+).

RESULTSSixty-two patients (62.0%) overexpressed PRAME. PRAME overexpression showed no prognostic significance to either overall survival (n = 100) or progression-free survival (PFS, n = 96, all P > 0.05) of patients. The patients were also categorized according to regimens with or without bortezomib. PRAME overexpression tended to be associated with a lower two-year PFS rate in patients treated with non-bortezomib-containing regimens (53.5% vs. 76.9%, P = 0.071). By contrast, it was not associated with the two-year PFS rate in patients with bortezomib-containing regimens (77.5% vs. 63.9%, P > 0.05). When the patients were categorized into PRAME (+) and PRAME (-) groups, treatment with bortezomibcontaining regimens predicted a higher two-year PFS rate in PRAME (+) patients (77.5% vs. 53.5%, P = 0.027) but showed no significant effect on two-year PFS rate in PRAME (-) patients (63.9% vs. 76.9%, P > 0.05).

CONCLUSIONPRAME overexpression might be an adverse prognostic factor of PFS in MM patients treated with non-bortezomib-containing regimens. Bortezomib improves PFS in patients overexpressing PRAME.

This study aimed to investigate the effect of bortezomib in the desensitization and treatment of acute antibody mediated rejection (AAMR) in kidney transplantation. Nine patients who received bortezomib therapy for desensitization (DSZ group, n = 3) or treatment of AAMR (AAMR group, n = 6) were included in this study. In the DSZ group, 2 patients required DSZ owing to positive cross match and 1 owing to ABO mismatch with high baseline anti-ABO antibody titer (1:1,024). Bortezomib was used at 1, 3, 8, and 11 days from the start of the treatment. In the AAMR group, 3 patients showed full recovery of allograft function after bortezomib use and decrease in donor specific anti-HLA antibody (HLA-DSA). However, 3 patients did not respond to bortezomib and experienced allograft failure. In the DSZ group, negative conversion of T-CDC (complement-dependent cytotoxicity) was achieved, and HLA-DSA was decreased to lower than a weak level (median fluorescence intensity [MFI] < 5,000) in 2 patients. In the case of ABO mismatch kidney transplantation, the anti-A/B antibody titer decreased to below the target (< or = 1:16) after bortezomib therapy. Therefore, bortezomib could be an alternative therapeutic option for desensitization and treatment of AAMR that is unresponsive to conventional therapies.

OBJECTIVETo evaluate the efficacy and safety of bortezomib-based chemotherapy for 80 patients with multiple myeloma (MM).

METHODSA total of 80 cases with a median age of 57 (range: 25-78) years were enrolled in the study. Bortezomib-based regimens included VD (bortezomib and dexamethasone) and PAD (bortezomib, doxorubicin and dexamethasone). 16 of the 80 patients received autologous or allo-hematopoietic stem cell transplantation (HSCT).

RESULTSThe overall response (OR) rate was 80%, including a complete response (CR) of 46.3%. After a median follow-up of 25 months, the 1-year and 2-year overall survival (OS) was 81.4% and 72.9%, and the 2-year progression-free survival (PFS) was 76% and 62.5%, respectively. The 2-year OS and PFS were 100% and 73.9 % in patients with HSCT, while both were 66% (P=0.029) and 58.7% (P=0.447) in patients without HSCT. In univariate analysis, Durie-Salmon group, ISS stage, CR and very good partial response (VGPR), and HSCT were prognostic factors for OS. Gender and extramedullary plasmacytomas were important prognostic factors for PFS. Multivariate analysis by Cox regression revealed that CR and VGPR, Durie-Salmon group A, and HSCT were prognostic factors for better OS; while male and patients without extramedullary plasmacytomas were prognostic factors for longer PFS.

CONCLUSIONMM patients could benefit from bortezomib-based chemotherapy with satisfactory efficacy and safety. HSCT could improve the OS for young MM patients.

Many advances in the treatment of multiple myeloma have been made due to the use of transplantation and the introduction of novel agents including thalidomide, lenalidomide, and bortezomib. The first step is recognizing the symptoms and starting prompt treatment. Different strategies should be selected for young and elderly subjects. Young patients are commonly eligible for transplantation, which is now considered the standard approach for this setting, and various inductions therapies containing novel agents are available before transplantation. Elderly patients are usually not eligible for transplantation, and gentler approaches with new drugs combinations are used for their treatment.
