Anti-Idiotypic VHHs and VHH-CAR-T Cells to Tackle Multiple Myeloma: Different Applications Call for Different Antigen-Binding Moieties. Int J Mol Sci 2024; 25:5634.

Abstract
CAR-T cell therapy is at the forefront of next-generation multiple myeloma (MM) management, with two B-cell maturation antigen (BCMA)-targeted products recently approved. However, these products are incapable of breaking the infamous pattern of patient relapse. Two contributing factors are the use of BCMA as a target molecule and the artificial scFv format that is responsible for antigen recognition. Tackling both points of improvement in the present study, we used previously characterized VHHs that specifically target the idiotype of murine 5T33 MM cells. This idiotype represents one of the most promising yet challenging MM target antigens, as it is highly cancer- but also patient-specific. These VHHs were incorporated into VHH-based CAR modules, the format of which has advantages compared to scFv-based CARs. This allowed a side-by-side comparison of the influence of the targeting domain on T cell activation. Surprisingly, VHHs previously selected as lead compounds for targeted MM radiotherapy are not the best (CAR-) T cell activators. Moreover, the majority of the evaluated VHHs are incapable of inducing any T cell activation. As such, we highlight the importance of specific VHH selection, depending on its intended use, and thereby raise an important shortcoming of current common CAR development approaches.

Efficacy of isatuximab in combination with steroids for the treatment of relapsed/refractory multiple myeloma patients exhibiting only biochemical progression-A single center retrospective study. Eur J Haematol 2023; 111:628-635. [PMID: 37485542 DOI: 10.1111/ejh.14057] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2023] [Revised: 07/06/2023] [Accepted: 07/10/2023] [Indexed: 07/25/2023]
Abstract
OBJECTIVES Isatuximab is approved for treatment of relapsed/refractory multiple myeloma (RRMM) with dexamethasone and carfilzomib or pomalidomide. Patients receiving these three-drug regimens have exhibited more Grade ≥ 3 adverse events (AEs) compared to the two-drug class combination of isatuximab and steroids alone. Thus, this single-center retrospective study investigated the efficacy of isatuximab with dexamethasone and methylprednisolone (ISAdm) for RRMM patients showing only biochemical progression (BP) of their disease. METHODS Twenty-four RRMM patients exhibiting only BP were administered isatuximab at 10 mg/kg with dexamethasone once weekly for cycle 1 of a 28-day cycle, followed by every other week for each cycle thereafter. Starting in cycle 2, oral methylprednisolone was added every other day stopping 48 h before and starting 48 h after each dexamethasone infusion. RESULTS Overall response rate and clinical benefit rate were 63% and 79%, respectively. Progression free survival was 12.9 months. There were only 5 AEs of Grade ≥ 3 which included lymphocytopenia (13%), leukopenia (4%), and neutropenia (4%). No Grade ≥ 3 AE related to respiratory infection, anemia, or thrombocytopenia were reported. CONCLUSION This study shows that the two-drug class combination of ISAdm is an effective and well tolerated treatment option for RRMM patients exhibiting only BP.

J Clin Med 2022; 11:jcm11195908. [PMID: 36233774 PMCID: PMC9572774 DOI: 10.3390/jcm11195908] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2022] [Revised: 09/27/2022] [Accepted: 10/04/2022] [Indexed: 11/28/2022] Open
Abstract
Lenalidomide-based regimens are effective treatment options for patients with relapsed/refractory multiple myeloma (RRMM). However, they are associated with an increased risk of infectious complications. This study examines the clinical factors influencing the occurrence of infection in MM patients treated with lenalidomide and dexamethasone (Rd). A retrospective analysis of all patients who received the Rd regimen between 2017 and 2021 at our institution was performed. The study group consisted of 174 patients and the median age was 65 years. Most patients (n = 110, 63.2%) received the Rd treatment in second-line treatment. The majority of patients (64.3%) received bortezomib-based regimens in the first line of treatment. The median progression-free survival was 12.6 (95% CI: 9.5–16.2) months, and the median overall survival was 22.3 (95% CI: 15.9–28.6) months. The overall response rate was 64.1%, 12.7% of patients achieved complete response, and 20.4% had a very good partial response. In multivariate logistic regression analysis, hypoalbuminemia (OR 4.2, 95% CI: 1.6–11.2, p = 0.0039), autologous hematopoietic stem cell transplantation (AHSCT) before Rd (OR 2.6, 95% CI: 1.0–6.7, p = 0.048), and anemia grade ≥3 (OR 5.0, 95% CI: 1.8–14.0, p = 0.002) were independent factors related to the occurrence of infections. In conclusion, in this large cohort of RRMM patients, AHSCT before Rd regimen therapy, hypoalbuminemia, and anemia during treatment were identified as three independent factors influencing the frequency of infections during Rd therapy. Patients with established risk factors may benefit from optimal supportive therapy.

Analysis of Serum IgG1 to Predict Progression and Therapeutic Effect in Patients with Multiple Myeloma. JOURNAL OF ONCOLOGY 2022; 2022:8628781. [PMID: 35342422 PMCID: PMC8947869 DOI: 10.1155/2022/8628781] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 01/04/2022] [Accepted: 01/26/2022] [Indexed: 01/10/2023]
Abstract
Objective The correlation between laboratory indicators and clinical treatment effects and the prognosis of multiple myeloma remains poorly understood. Therefore, our study investigated whether serum IgG subclasses could be employed as potential indicators contributed to evaluate the therapeutic effect and prognosis of patients with multiple myeloma. Patients and Methods. Records of patients with multiple myeloma were initially diagnosed at the First Affiliated Hospital of Soochow University, China, from August 1, 2017, to February 28, 2020. The assessment abilities of serological indicators for therapeutic effect were evaluated in patients compared with healthy controls. Results In 560 study patients with multiple myeloma, serum IgA, IgG, IgM, κ-LC, and λ-LC increased by15%, 33.04%, 1.96%, 27.50%, and 26.43%, respectively. Further analysis found that IgG1, IgG2, IgG3, and IgG4 were over the upper limit of the reference range with 26.38%, 6.09%, 8.12%, and 4.64%, respectively. κ-LC and λ-LC were found in the urine in 65.13% and 29.70%, respectively. In peripheral blood, the proportion of CD3+CD4+, CD3−CD19+ cells, and CD4+/CD8+ decreased, whereas CD3+CD8+ cells and CD16+/CD56+ increased, and the associated cytokines IL-2, IL-4, IL-6, TNF-α, and IFN-γ were upregulated in patients when compared with healthy controls. Furthermore, the serum levels of IgA, IgG, IgG1, IgG2, IgG3, and IgG4 gradually decreased in patients before, during, and after treatment. Similar results were found in serum and urine κ-LC and λ-LC. Conclusion Serum IgG1 level could serve as the potential indicator for evaluating the therapeutic effect for patients with multiple myeloma. κ-LC and λ-LC also have the potential to be prognostic indicators. More studies are warranted to explore these serological indicators for personalized therapy in the future.

The Key Role of Hepcidin-25 in Anemia in Multiple Myeloma Patients with Renal Impairment. Medicina (B Aires) 2022; 58:medicina58030417.

Abstract
Background and objectives: Anemia is common in multiple myeloma (MM) and is caused by a complex pathomechanism, including impaired iron homeostasis. Our aim is to evaluate the biomarkers of iron turnover: serum soluble transferrin receptor (sTfR) and hepcidin-25 in patients at various stages of MM in relation with markers of anemia, iron status, inflammation, renal impairment and burden of the disease and as predictors of mortality. Materials and methods: Seventy-three MM patients (six with smoldering and 67 with symptomatic disease) were recruited and observed for up to 27 months. Control group included 21 healthy individuals. Serum sTfR and hepcidin were measured with immunoenzymatic assays. Results: MM patients with and without anemia had higher sTFR compared to controls, while only anemic patients had higher hepcidin-25. Both hepcidin-25 and sTfR were higher in anemic than non-anemic patients. Higher hepcidin-25 (but not sTfR) was associated with increasing MM advancement (from smoldering to International Staging System stage III disease) and with poor response to MM treatment, which was accompanied by lower blood hemoglobin and increased anisocytosis. Neither serum hepcidin-25 nor sTfR were correlated with markers of renal impairment. Hepcidin-25 predicted blood hemoglobin in MM patients independently of other predictors, including markers of renal impairment, inflammation and MM burden. Moreover, both blood hemoglobin and serum hepcidin-25 were independently associated with patients’ 2-year survival. Conclusions: Our results suggest that hepcidin-25 is involved in anemia in MM and its concentrations are not affected by kidney impairment. Moreover, serum hepcidin-25 may be an early predictor of survival in this disease, independent of hemoglobin concentration. It should be further evaluated whether including hepcidin improves the early diagnosis of anemia in MM.

Abstract
As is the case for solid tumors, treatment paradigms have shifted from non-specific chemotherapeutic agents towards novel targeted drugs in the treatment of patients with multiple myeloma (MM). Currently, multiple targeted therapies are available to treat patients augmenting the arsenal of modalities which also includes chemotherapy, immunotherapy, radiation therapy, hematopoietic stem cell transplantation (HSCST) and chimeric antigen T-cell therapy (CAR-T). These novel, targeted agents have dramatically increased optimism for patients, who may now be treated over many years with successive regimens. As fortunate as we are to have these new therapies available for our patients, this advantage is juxtaposed with the challenges involved with delivering them safely. While each class of agents has demonstrated efficacy, in terms of response rates and survival, they also exert class effects which pose risks for toxicity. In addition, newer generation agents within the classes often have slightly different toxicity profiles than did their predecessors. These factors must be addressed, and their risks mitigated by the multidisciplinary team. This review presents a summary of the evolution of drug development for MM. For each targeted agent, the efficacy data from pivotal trials and highlights of the risks that were demonstrated in trials, as well as during post-marketing surveillance, are presented. Specific risks associated with agents within the classes, that are not shared with all new class members, are described. A table presenting these potential risks, with recommended nursing actions to mitigate toxicity, is provided as a quick reference that nurses may use during the planning, and provision, of patient care.

Abstract
Objective: The correlation between low triiodothyronine (T3) syndrome and shorter survival in malignant tumor patients has been increasingly reported. The objective of the present study was to investigate the association between low T3 syndrome and survival in multiple myeloma (MM) patients. Methods: A total of 201 newly diagnosed MM patients were included in this retrospective study. All participants were divided into 2 groups based on serum free T3 (FT3) level: low T3 syndrome group (FT3 < 2.3 pg/mL) and non-low T3 syndrome group (FT3 ≥ 2.3 pg/mL). Baseline clinical characteristics, overall survival (OS) and progression free survival (PFS) were analyzed. Results: 80 (39.8%) patients had low T3 syndrome. Patients with low T3 syndrome had significantly lower blood hemoglobin and albumin, higher creatinine and β2-microglobulin (β2-MG), higher neutrophil/lymphocyte and (neutrophil + monocyte)/lymphocyte ratio, and more advanced ISS and R-ISS stages (all P < .05). Serum FT3 level was positively associated with blood hemoglobin and albumin, and negatively correlated with β2-MG, creatinine, neutrophil/lymphocyte ratio, and (neutrophil + monocyte)/lymphocyte ratio (all P < .05). Patients with low T3 syndrome had significantly inferior OS time and PFS time (both P < .001). In multivariate Cox analysis, low T3 syndrome was found to be an independent factor associated with OS (P < .001) and PFS (P = .002). Receiver operator characteristic curve analyses showed that FT3 was a predictive marker for death during the entire follow-up period (the area under the curve [AUC] = 0.720, P < .001) and during 1 year (AUC = 0.747, P < .001). Conclusion: Low T3 syndrome might be useful for predicting survival in patients with newly diagnosed MM.

High Carbohydrate Diet Is Associated with Severe Clinical Indicators, but Not with Nutrition Knowledge Score in Patients with Multiple Myeloma.

Abstract
Although the survival rate of patients diagnosed with multiple myeloma has doubled over the last few decades, due to the introduction of new therapeutic lines and improvement of care, other potential contributors to the therapeutic response/relapse of disease, such as nutrient intake, along with nutrition knowledge, have not been assessed during the course of the disease. The purpose of this research was to assess nutrition knowledge and diet quality in a group of patients with a diagnosis of multiple myeloma. Anthropometric, clinical and biological assessments and skeletal survey evaluations, along with the assessment of nutritional intake and general nutrition knowledge, were performed on 61 patients with a current diagnosis of multiple myeloma. A low carbohydrate diet score was computed, classified in tertiles, and used as a factor in the analysis. Patients in tertiles indicative of high carbohydrate or low carbohydrate intake showed significant alteration of clinical parameters, such as hemoglobin, uric acid, albumin, total proteins, beta-2 microglobulin, percentage of plasmacytes in the bone marrow and D-dimers, compared to patients in the medium carbohydrate intake tertile. Nutrition knowledge was not associated with clinical indicators of disease status, nor with patterns of nutrient intake. Better knowledge of food types and nutritional value of foods, along with personalized nutritional advice, could encourage patients with MM to make healthier decisions that might extend survival.

Abstract
Infection is associated with great morbidity and mortality in patients with multiple myeloma (MM), but evidence for invasive fungal infections (IFIs) is lacking. We aimed to investigate risk factors for IFI in MM patients and to determine its impact on patients' survival. We retrospectively analyzed MM patients at Taipei Veterans General Hospital in Taiwan between January 2002 and October 2018. MM was diagnosed according to the International Myeloma Working Group criteria. IFI was defined according to the European Organization for Research and Treatment of Cancer/Mycoses Study Group criteria. All risk factors of IFI in MM patients were estimated using Cox regression models in the univariate and multivariate analyses. Of the 623 patients recruited, 22 (3.5%) were diagnosed with proven or probable IFI. Light chain disease (adjusted hazard ratio [HR] 6.74, 95% confidence interval [CI] 2.10-21.66), hemoglobin less than 8 g/dl (adjusted HR 3.34, 95% CI 1.32-8.42), serum albumin < 3.5 g/dl (adjusted HR 3.24, 95% CI 1.09-9.68), and having received allogeneic stem cell transplantation (allo-SCT) (adjusted HR 5.98, 95% CI 1.62-22.03) were significantly associated with IFI in the multivariate analysis. Contracting IFI was in turn associated with early mortality (adjusted HR 11.60, 95% CI 1.26-106.74). Light chain disease, anemia, hypoalbuminemia, and receiving allo-SCT were independent predictors of IFI in MM patients. The early mortality risk is much higher in those encountering IFI. Physicians must be aware of the rare but potentially lethal infections.

Abstract
Multiple myeloma (MM) is a malignancy of clonal plasma cells accounting for approximately 10% of haematological malignancies. MM mainly affects older patients, more often males and is more frequently seen in African Americans. The most frequent manifestations of MM are anaemia, osteolytic bone lesions, kidney failure and hypercalcemia. The anaemia develops secondary to suppression of erythropoiesis by cytokine networks, similarly to the mechanism of anaemia of chronic disease. The concomitant presence of kidney failure, especially chronic kidney disease (CKD) and MM per se, leading to anaemia of chronic disease (ACD) in combination, provoked us to pose the question about their reciprocal dependence and relationship with specific biomarkers; namely, soluble transferrin receptor (sTfR), growth differentiation factor 15 (GDF15), hepcidin 25 and zonulin. One or more of these are new biomarkers of ferric management may be utilized in the near future as prognostic predictors for patients with MM and kidney failure.

Abstract
PURPOSE To investigate the relationship between physical function and quality of life in multiple myeloma patients. METHODS In this retrospective cross-sectional study, data from patients with multiple myeloma (N = 63), who were referred to the department of Rehabilitation Medicine from October 2017 to May 2018, were reviewed. Patients were excluded based on the following criteria: acute illness, unstable medical conditions, impaired cognition or communication, refusal, or inability to perform the assessment. Physical function was evaluated with the Mini-Balance Evaluation Systems Test (Mini-BESTest), and the European Organization for Research and Treatment of Cancer questionnaires QLQ-C30 and QLQ-MY20 were used for the evaluation of quality of life. To evaluate fatigue and psychotic status, the Fatigue Severity Scale and Beck Depression Inventory were used. Patients were divided into two groups ("good-function group" and "poor-function group"), based on previously studied normative values of the Mini-BESTest. Clinical data was reviewed to interrogate the contributing factors of physical function. RESULTS Positive correlations were observed between Mini-BESTest scores and all domains of the QLQ-C30. The Mini-BESTest score was lower in patients with lower serum hemoglobin (r = 0.396, p = 0.001) and albumin levels (r = 0.440, p < 0.001), severe disease-related symptoms (r = - 0.39, p = 0.02), and depression (r = - 0.538, p < 0.001). Further, the poor-function group showed lower hemoglobin (p = 0.024) and albumin levels (p = 0.004). CONCLUSION In patients with multiple myeloma, physical function had a significant relationship with quality of life. Low hemoglobin and albumin levels, severe disease- or treatment-related symptoms, and depression were related to decreased physical function, and thus consequentially exert an effect on quality of life in multiple myeloma patients.

Abstract
Objective The aim of this study was to evaluate the relation between the rate of fluorine-18 (18F) fludeoxyglucose (FDG) uptake and CD38 and CD138 expression in myeloma cells in bone marrow and other clinical parameters in patients with multiple myeloma (MM). Materials and Methods Patients with the diagnosis of MM who underwent 18F-FDG positron emission tomography/computed tomography (PET/CT) for initial staging were evaluated retrospectively. We analyzed a total of 42 patients (43-83 years old, mean: 64.4±9.9). Hematological and biochemical tests including hemoglobin, hematocrit, C-reactive protein, β2-microglobulin, creatinine, albumin, calcium, lactate dehydrogenase, and erythrocyte sedimentation rate were recorded. In bone marrow samples, plasma cell ratio and CD38 and CD138 immunohistochemical staining were evaluated. On PET/CT images, mean standardized uptake values (SUVmean) of the right anterior and posterior iliac crest and right proximal femora were calculated. The correlations between the average SUVmean of bone marrow and CD38- and CD138-expressing myeloma cells and other parameters were analyzed by Spearman’s correlation test. Values of p<0.05 were considered statistically significant. Results Types of MM were IgGK (45%), IgGL (21%), IgAK (7%), IgAL (10%), and others (17%). Thirty-two (76%) patients were at stage III according to the Salmon-Durie staging system. There was a statistically significant positive correlation between bone marrow FDG uptake and percentage of plasma cells in bone marrow and CD38 and CD138 expression in plasma cells (r=0.403, r=0.339, and r=0.409) and β2-microglobulin and C-reactive protein levels (r=0.676, r=0.541). There was a negative correlation between bone marrow FDG uptake and hemoglobin and hematocrit values (r=-0.377 and r=-0.368). Other hematological parameters were not correlated with FDG uptake in bone marrow. Conclusion Increased FDG uptake is correlated with the percentage of CD38 and CD138 expression in plasma cells in bone marrow. In addition to initial staging, 18F-FDG PET/CT is useful in treatment planning and prognostic evaluation in MM patients.

Abstract
B-cell maturation antigen is expressed on plasma cells. In this study, we have identified serum B-cell maturation antigen as a novel biomarker that can monitor and predict outcomes for multiple myeloma patients. Compared to healthy donors, patients with multiple myeloma showed elevated serum B-cell maturation antigen levels (P<0.0001). Serum B-cell maturation antigen levels correlated with the proportion of plasma cells in bone marrow biopsies (Spearman's rho = 0.710; P<0.001), clinical status (complete response vs partial response, P=0.0374; complete response vs progressive disease, P<0.0001), and tracked with changes in M-protein levels. Among patients with non-secretory disease, serum B-cell maturation antigen levels correlated with bone marrow plasma cell levels and findings from positron emission tomography scans. Kaplan-Meier analysis demonstrated that serum B-cell maturation antigen levels above the median levels were predictive of a shorter progression-free survival (P=0.0006) and overall survival (P=0.0108) among multiple myeloma patients (n=243). Specifically, patients with serum B-cell maturation antigen levels above the median level at the time of starting front-line (P=0.0043) or a new salvage therapy (P=0.0044) were found to have shorter progression-free survival. Importantly, serum B-cell maturation antigen levels did not show any dependence on renal function and maintained independent significance when tested against other known prognostic markers for multiple myeloma such as age, serum β2 microglobulin, hemoglobin, and bone disease. These data identify serum B-cell maturation antigen as a new biomarker to manage multiple myeloma patients.

Abstract
Auto-immun events are rare in multiple myeloma (MM). Here, we report one MM case complicated by Evans syndrome (Autoimmun hemolytic anemia (AIHA) associated with thrombocytopenia). A 52-year-old man was admitted in nephrology department with severe anemia, renal insufficiency and hypergamma globulinemia. Laboratory exams showed acute hemolysis due to an IgG warm autoantibody. Serum electrophoresis revealed the presence of a monoclonal IgG protein and urinary M protein was 2g/day. A whole body CT-Scan showed osteolytic lesions of vertebral body of C5, D4, L3, L4 and the left iliac wing. The diagnosis of multiple myeloma and Evan's syndrome was made, we underwent chemotherapy by BTD (bortezomib-thalidomide-dexamethasone) and continuous corticosteroid therapy but unfortunately the patient died secondary of a Lactic acidosis. The relationship between MM and hemolysis remain unclear.

Abstract
Amyloidosis (AL) is a well recognized cause of macroglossia. A case of localized deposition of systemic amyloidosis secondary to multiple myeloma is reported in a 63-year-old female presenting with restricted tongue movement in the dental setting. Amyloidosis secondary to multiple myeloma is well documented in the literature, with amyloid deposits being found at various sites throughout the oral cavity and systemically. This case emphasizes the importance of a full oral soft tissue examination, including the need to examine mobility of the tissues, as it was the restricted movement of the tongue that ultimately alerted the clinician to the diagnosis. This report also highlights other dental implications of managing patients with multiple myeloma and amyloidosis. Clinical relevance: To provide an understanding of what multiple myeloma and amyloidosis are whilst, importantly, relating this to how these conditions can impact on routine dental treatment.

Abstract
PURPOSE Infiltration of the bone marrow by neoplastic plasmocytes in multiple myeloma (MM) patients might impair megakaryocytopoiesis. The aim of the study was to evaluate stage-dependent platelet count (PLT) and thrombopoietin (TPO) concentration in comparison to the control group. We also wanted to establish whether TPO might be recognized as a marker of the stage of the disease. MATERIAL/METHODS The study group consisted of 41 patients (mean age 67.7) with newly diagnosed MM prior to treatment and categorized according to the Durie and Salmon diagnostic classification. The control group consisted of 30 healthy subjects (mean age 65.5). PLT, WBC, RBC and Hb were measured with the use of the haematological analyser. TPO was assayed with the use of ELISA and albumin with the use of the immunonephelometry method. The number of plasma cells in the bone marrow was evaluated in bone marrow smears under light microscopy. RESULTS PLT was not statistically different as compared the control groups, but was stage-dependent. Thrombocytopenia was observed in the III stage of MM. TPO median was significantly higher in study group than in healthy subjects and it was increasing considerably with the stage of the disease. TPO concentration was negatively correlated with albumin and PLT. AUC for TPO was 0.9764. The number of plasma cells in the bone marrow was considerably increasing with the stage of the disease. CONCLUSIONS PLT and TPO in MM patients were stage-dependent. Elevated TPO concentration in MM patients might be an unfavourable marker of the stage of the disease.

Abstract
Multiple myeloma (MM) is a malignant disease of plasma cells and is often accompanied by anemia which may influence its progression and survival. The mechanism of anemia of chronic disease (ACD) in which iron homeostasis is impaired underlies that of MM-related anemia. In this study, we analyzed the role of hepcidin which is the main mediator of ACD and ACD-related cytokines in peripheral blood of MM patients. We showed that HAMP mRNA and growth differentiation factors 15 (GDF15) mRNA expressions in peripheral blood mononuclear cells (PBMCs) and plasma hepcidin, GDF15, interleukin-6 and erythropoietin in MM patients all increased significantly as compared to those in controls. In MM patients, the expression of HAMP mRNA showed a positive correlation with serum ferritin level, and a negative correlation with hemoglobin level. The levels of plasma hepcidin and GDF15 were significantly decreased in MM patients who achieved complete remission after six cycles VD (bortezomib + dexamethasone) regimen chemotherapy. These data indicated that overexpression of HAMP mRNA in PBMCs significantly correlated with increased plasma hepcidin level and may be involved in the pathogenesis of MM-related anemia. Furthermore, the levels of plasma hepcidin and GDF15 may be valuable in assessing the progress of MM.

Abstract
Multiple myeloma is a non-curable B-cell malignancy in which iron metabolism plays an important role. Patients with this disorder almost universally suffer from clinically significant anemia, which is often symptomatic, and which is due to impaired iron utilization. Recent studies have indicated that the proximal cause of dysregulated iron metabolism and anemia in these patients is cytokine-induced upregulation of hepcidin expression. Malignant myeloma cells are dependent on an increased influx of iron, and therapeutic efforts are being made to target this requirement. The studies detailing the characteristics and biochemical abnormalities in iron metabolism causing anemia and the initial attempts to target iron therapeutically are described in this review.

Abstract
Erythropoietin (Epo) is an essential hormone that binds and activates the Epo receptor (EpoR) resident on the surface of erythroid progenitor cells, thereby promoting erythropoiesis. Recombinant human erythropoietin has been used successfully for over 20 years to treat anemia in millions of patients. In addition to erythropoiesis, Epo has also been reported to have other effects, such as tissue protection and promotion of tumor cell growth or survival. This became of significant concern in 2003, when some clinical trials in cancer patients reported increased tumor progression and worse survival outcomes in patients treated with erythropoiesis-stimulating agents (ESAs). One of the potential mechanisms proffered to explain the observed safety issues was that functional EpoR was expressed in tumors and/or endothelial cells, and that ESAs directly stimulated tumor growth and/or antagonized tumor ablative therapies. Since then, numerous groups have performed further research evaluating this potential mechanism with conflicting data and conclusions. Here, we review the biology of endogenous Epo and EpoR expression and function in erythropoiesis, and evaluate the evidence pertaining to the expression of EpoR on normal nonhematopoietic and tumor cells.

Abstract
Anemia is a common side-effect of patients with multiple myeloma (MM) and lymphoma. The etiology is complex, but the main cause is the underlying mechanism of anemia of chronic disease, which is characterized among others, by impairment of iron metabolism and consequently iron restricted erythropoiesis (IRE), resulting from the up-regulation of the iron distributing regulator, hepcidin. Erythopoiesis-stimulating agents (ESAs) have been the standard of care since early 90's offering high response rates and improving the quality of life of the patients. However, the role of ESAs in the treatment of cancer-related anemia has been questioned recently, due to the growing evidence which support that ESAs may be associated with increased risk for thrombosis and may have a detrimental impact on patients' survival. Under the light of the recent considerations, the place of ESAs in the management of cancer-related anemia has been reassigned. Regarding the management of anemia in MM or lymphoma, the updated American Society of Clinical Oncology/American Society of Hematology (ASCO/ASH) 2007 clinical practice guidelines on the use of ESAs in cancer-related anemia, recommended that ESAs should be preferably omitted in patients planned to receive chemotherapy and applied in case that anemia does not improve over treatment. The quest for reliable predictors for response to ESAs and for indicators of IRE which plays a major etiological role for the development of anemia of cancer still remains an open issue. In the current review we present an update on ESAs use in anemia of MM and lymphoma.

Abstract
PURPOSE Hepcidin is a liver-produced peptide implicated in the anemia of inflammation. Because interleukin (IL)-6 is a potent inducer of hepcidin expression and its levels are elevated in multiple myeloma, we studied the role of hepcidin in the anemia of multiple myeloma. EXPERIMENTAL DESIGN Urinary hepcidin and serum levels of IL-6, ferritin, C-reactive protein, tumor necrosis factor-alpha, and IL-1 beta were studied in newly diagnosed myeloma patients. In vitro hepcidin induction assay was assessed by real-time PCR assay. RESULTS Pretreatment urinary hepcidin levels in 44 patients with stage III multiple myeloma were 3-fold greater than normal controls. In the subset of multiple myeloma patients without renal insufficiency (n = 27), a marked inverse correlation was seen between hemoglobin at diagnosis and urinary hepcidin level (P = 0.014) strongly supporting a causal relationship between up-regulated hepcidin expression and anemia. The urinary hepcidin also significantly (P < 0.05) correlated with serum ferritin and C-reactive protein, whereas its correlation with serum IL-6 levels was of borderline significance (P = 0.06). Sera from 14 multiple myeloma patients, with known elevated urinary hepcidin, significantly induced hepcidin mRNA in the Hep3B cells, whereas normal sera had no effect. For 10 patients, the ability of anti-IL-6 and anti-IL-6 receptor antibodies to prevent the serum-induced hepcidin RNA was tested. In 6 of these patients, hepcidin induction was abrogated by the anti-IL-6 antibodies, but in the other 4 patients, the neutralizing antibodies had no effect. CONCLUSIONS These results indicate hepcidin is up-regulated in multiple myeloma patients by both IL-6-dependent and IL-6-independent mechanisms and may play a role in the anemia of multiple myeloma.

Abstract
Approximately 5-10% of patients with chronic kidney disease demonstrate hyporesponsiveness to erythropoiesis-stimulating agents (ESA), defined as a continued need for greater than 300 IU/kg per week erythropoietin or 1.5 mug/kg per week darbepoetin administered by the subcutaneous route. Such hyporesponsiveness contributes significantly to morbidity, mortality and health-care economic burden in chronic kidney disease and represents an important diagnostic and management challenge. The commonest causes of ESA resistance are non-compliance, absolute or functional iron deficiency and inflammation. It is widely accepted that maintaining adequate iron stores, ideally by administering iron parenterally, is the most important strategy for reducing the requirements for, and enhancing the efficacy of ESA. There have been recent epidemiologic studies linking parenteral iron therapy to an increased risk of infection and atherosclerosis, although other investigations have refuted this. Inflammatory ESA hyporesponsiveness has been reported to be improved by a number of interventions, including the use of biocompatible membranes, ultrapure dialysate, transplant nephrectomy, ascorbic acid therapy, vitamin E supplementation, statins and oxpentifylline administration. Other variably well-established causes of ESA hyporesponsiveness include inadequate dialysis, hyperparathyroidism, nutrient deficiencies (vitamin B12, folate, vitamin C, carnitine), angiotensin-converting enzyme inhibitors, angiotensin receptor blockers, aluminium overload, antibody-mediated pure red cell aplasia, primary bone marrow disorders, myelosuppressive agents, haemoglobinopathies, haemolysis and hypersplenism. This paper reviews the causes of ESA hyporesponsiveness and the clinical evidence for proposed therapeutic interventions. A practical algorithm for approaching the investigation and management of patients with ESA hyporesponsiveness is also provided.

Abstract
The aim of the study was to evaluate the role of hypochromic erythrocytes (HYPO%) compared to "traditional" and novel markers of iron status and erythropoiesis in recognizing iron-restricted erythropoiesis (IRE) and predicting response to erythropoietin (rHuEPO) in anemic patients with myeloma and lymphoma. Forty-one newly diagnosed patients who received epoetin-beta at a subcutaneous weekly dose of 30,000 IU for 6 weeks were studied. Response to rHuEPO was observed in 27 patients (65.8%). Twelve non-responders received, additionally, 200 mg of IV iron sucrose, weekly, for 4 weeks. Evaluation of markers was performed at baseline and on weeks 1, 2 and 6 for all patients and also on weeks 7-10 for non-responders to rHuEPO. Baseline HYPO%, at a cut-off value of <5%, and an increment in reticulocyte absolute number (RETICS-AB) >or= 50,000/microl and reticulocyte hematocrit (RETICS-Hct) >or= 50%, between baseline and week 2, were independent predictive factors for response to rHuEPO. We found that these markers had superior predictive value for response to rHuEPO than four widely used predictive models. Furthermore, a baseline HYPO% count of above 5% proved superior over serum ferritin < 100 ng/ml and transferrin saturation < 20% in recognizing IRE. In conclusion, baseline HYPO% either alone or in combination with RETICS-AB or RETICS-Hct after 2 weeks of rHuEPO treatment could be reliably used in predicting response to rHuEPO. Additionally, HYPO% has proved a reliable marker for recognizing IRE before rHuEPO treatment and, thus, could be used for identifying patients who will benefit from IV iron supplementation.

Abstract
Significant progress in the treatment of multiple myeloma has resulted in improvement of disease control with a trend toward overall and progression-free survival benefit. With the availability of several new therapeutic agents and combinations, a careful emphasis should be placed in the management of disease- and therapy-associated complications. Aggressive management of these complications can impact patients' quality of life as well as treatment outcome. This review highlights some of the critical supportive care measures integral to the optimal care of patients with multiple myeloma.

Abstract
Safety concerns surrounding the use of recombinant human erythropoietin (Epo) to treat anemia in cancer patients were raised after 2 recent clinical studies reported a worse survival outcome in patients who received epoetin alpha or epoetin beta compared with patients who received placebo. Although those findings contrasted with previous clinical studies, which demonstrated no difference in survival for cancer patients who received erythropoiesis-stimulating agents (ESAs), some investigators have suggested a potential role for ESAs in promoting tumor growth through 1) stimulation of Epo receptors (EpoR) expressed in tumors, 2) stimulation and formation of tumor vessels, and/or 3) enhanced tumor oxygenation. The first and second hypotheses appeared to be supported by some EpoR expression and ESA in vitro studies. However, these conclusions have been challenged because of poor specificity of EpoR-detection methodologies, conflicting data from different groups, and the lack of correlation between in vitro data and in vivo findings in animal tumor models. For this report, the authors reviewed the biology of EpoR in erythropoiesis and compared and contrasted the reported findings on the role of ESAs and EpoR in tumors.

Abstract
Erythropoietin (Epo) is the main growth regulator of red blood cells, and recombinant human erythropoietin (rHuEpo) is thus used in clinical practice for the treatment of anaemia, primarily in kidney disease and cancer. rHuEpo treatment was found to be associated with prolonged survival of multiple myeloma (MM) patients. This clinical observation was then supported by studies on murine myeloma models. It thus appeared that rHuEpo had an anti-myeloma effect, causally related to an immunomodulatory function of rHuEpo. The present study investigated whether rHuEpo-treated MM patients acquire improved immunological functions. Treatment with rHuEpo, prescribed for anaemia that occurs in advanced disease, was associated with effects on a variety of immunological parameters and functions. This was expressed in an actual normalisation of the CD4:CD8 cell ratio, enhanced T cell phytohaemagglutinin-mediated activation and proliferation potential, T cell expression of the costimulatory CD28 and inhibitory CTLA-4 molecules, as well as reduced interleukin-6 serum values to normal levels. Furthermore, it was demonstrated that immunological abnormalities manifest in patients even in the early stages of MM. Our findings thus suggest that rHuEpo treatment might be effective in the early stages of MM, before anaemia develops. It is expected that this would boost the immune system, consequently achieving an anti-myeloma function; affecting disease progression and improving the prognosis.

Abstract
Multiple myeloma (MM) is a B cell lymphoproliferative disorder in which malignant plasma cells accumulate in the bone marrow and usually produce monoclonal immunoglobulin in excess. Interleukin-6 (IL-6), is known to be an essential survival factor of myeloma cells, high IL-6 levels being correlated with an adverse prognosis. IL-6 modulates the transcription of several liver-specific acute phase protein genes, including C-reactive protein and hepcidin. Anemia is one of the prominent features of MM, along with recurrent osteolytic lesions, bacterial infections and renal insufficiency. The current treatment strategies of MM related anemia are often inadequate and many patients rely on transfusions. Several causes have been implicated, but anemia of chronic disease (ACD) related to the inflammatory cytokines appears to be one of the main culprits. The pathogenesis of ACD had been poorly understood, but recently it has been shown that increased Il-6 upregulates the hepatic production of hepcidin, which, by binding to its cellular receptor, ferroportin, causes anemia by blocking iron export from enterocytes and macrophages. We hereby argue that by virtue of its biological characteristics, multiple myeloma should be an ideal clinical setting to test the role of hepcidin in the pathogenesis of ACD. Hepcidin levels should be higher in MM patients and might correlate with prognosis. Anemic MM patients should also be among those who would benefit mostly from hepcidin targeted therapies.

Abstract
The etiology of most chronic angiogenic diseases such as rheumatoid arthritis, atherosclerosis, diabetes complications, and cancer includes the presence of pockets of hypoxic cells growing behind aerobic cells and away from blood vessels. Hypoxic cells are the result of uncontrolled growth and insufficient vascularization and have undergone a shift from aerobic to anaerobic metabolism. Cells respond to hypoxia by stimulating the expression of hypoxia inducible factor (HIF), which is critical for survival under hypoxic conditions and in embryogenesis. HIF is a heterodimer consisting of the O2-regulated subunit, HIF-1alpha, and the constitutively expressed aryl hydrocarbon receptor nuclear translocator, HIF-1beta. Under hypoxic conditions, HIF-1alpha is stable, accumulates, and migrates to the nucleus where it binds to HIF-1beta to form the complex (HIF-1alpha + HIF-1beta). Transcription is initiated by the binding of the complex (HIF-1alpha + HIF-1beta) to hypoxia responsive elements (HREs). The complex [(HIF-1alpha + HIF-1beta) + HREs] stimulates the expression of genes involved in angiogenesis, anaerobic metabolism, vascular permeability, and inflammation. Experimental and clinical evidence show that these hypoxic cells are the most aggressive and difficult angiogenic disease cells to treat and are a major reason for antiangiogenic and conventional treatment failure. Hypoxia occurs in early stages of disease development (before metastasis), activates angiogenesis, and stimulates vascular remodeling. HIF-1alpha has also been identified under aerobic conditions in certain types of cancer. This review summarizes the role of hypoxia in some chronic degenerative angiogenic diseases and discusses potential functional foods to target the HIF-1alpha pathways under hypoxic and normoxic conditions. It is reported that dietary quinones, semiquinones, phenolics, vitamins, amino acids, isoprenoids, and vasoactive compounds can down-regulate the HIF-1 pathways and therefore the expression of several proangiogenic factors. Considering the lack of efficiency or the side effects of synthetic antiangiogenic drugs at clinical trials, down-regulation of hypoxia-induced angiogenesis by use of naturally occurring functional foods may provide an effective means of prevention.
