Abstract
Multiple myeloma (MM) is a very heterogeneous disease with multiple symptoms and clinical manifestations. MM affects mainly elderly patients and is difficult to manage in the presence of comorbidities, polypharmacy, frailty and adverse events of disease-targeted drugs. The rapid changes in MM treatment resulting from constant innovations in this area, together with the introduction of numerous new drugs with distinct mechanisms of action and toxicity profiles, have led to an increased complexity in the therapeutic decision-making and patient management processes. The prolonged exposure to novel agents, sometimes in combination with conventional therapies, makes this management even more challenging. A careful balance between treatment efficacy and its tolerability should be considered for every patient. During treatment, a close monitoring of comorbidities, disease-related manifestations and treatment side effects is recommended, as well as a proactive approach, with reinforcement of information and patient awareness for the early recognition of adverse events, allowing prompt therapeutic adjustments. In this review, we discuss various issues that must be considered in the treatment of MM patients, while giving practical guidance for monitoring, prevention and management of myeloma-related manifestations and treatment-related toxicities.

Abstract
OBJECTIVES To report healthcare resource utilization (HCRU) and safety outcomes in systemic light chain (AL) amyloidosis from the EMN23 study. MATERIALS AND METHODS The retrospective, observational, multinational EMN23 study included 4,480 patients initiating first-line treatment for AL amyloidosis in 2004-2018 and assessed, among other objectives, HCRU and safety outcomes. HCRU included hospitalizations, examinations, and dialysis; safety included serious adverse events (SAEs) and adverse events of special interest (AESIs). Data were descriptively analyzed by select prognostic factors (e.g., cardiac staging by Mayo2004/European) for 2004-2010 and 2011-2018. A cost-of-illness analysis was conducted for the UK and Spain. RESULTS HCRU/safety and dialysis data were extracted for 674 and 774 patients, respectively. Of patients with assessed cardiac stage (2004-2010: 159; 2011-2018: 387), 67.9% and 61.0% had ≥ 1 hospitalization, 56.0% and 51.4% had ≥ 1 SAE, and 31.4% and 28.9% had ≥ 1 AESI across all cardiac stages in 2004-2010 and 2011-2018, respectively. The per-patient-per-year length of hospitalization increased with disease severity (cardiac stage). Of patients with dialysis data (2004-2010: 176; 2011-2018: 453), 23.9% and 14.8% had ≥ 1 dialysis session across all cardiac stages in 2004-2010 and 2011-2018, respectively. The annual cost-of-illness was estimated at €40,961,066 and €31,904,386 for the UK and Spain, respectively; dialysis accounted for ∼28% (UK) and ∼35% (Spain) of the total AL amyloidosis costs. CONCLUSIONS EMN23 showed that the burden of AL amyloidosis is substantial, highlighting the need for early disease diagnosis and effective treatments targeting the underlying pathology.

Abstract
18F-Fluorodeoxyglucose positron emission tomography/computed tomography (PET) positivity after first-line treatment with autologous stem cell transplantation (ASCT) in multiple myeloma is strongly correlated with reduced progression-free and overall survival. However, PET-positive patients who achieve PET negativity after treatment seem to have comparable outcomes to patients who were PET negative at diagnosis. Hence, giving PET-positive patients additional treatment may improve their outcome. In this phase II study, we screened first-line patients with very good partial response (VGPR) or better after ASCT with PET. PET-positive patients received four 28-day cycles of carfilzomib-lenalidomide-dexamethasone (KRd). Flow cytometry-based minimal residual disease (MRD) analysis was performed before and after treatment for correlation with PET. Overall, 159 patients were screened with PET. A total of 53 patients (33%) were PET positive and 57% of PET-positive patients were MRD negative, demonstrating that these response assessments are complementary. KRd consolidation converted 33% of PET-positive patients into PET negativity. MRD-negative patients were more likely to convert than MRD-positive patients. In summary, PET after ASCT detected residual disease in a substantial proportion of patients in VGPR or better, even in patients who were MRD negative, and KRd consolidation treatment changed PET status in 33% of patients.

Abstract
The objective is to assess the performance of seven semiautomatic and two fully automatic segmentation methods on [18F]FDG PET/CT lymphoma images and evaluate their influence on tumor quantification. All lymphoma lesions identified in 65 whole-body [18F]FDG PET/CT staging images were segmented by two experienced observers using manual and semiautomatic methods. Semiautomatic segmentation using absolute and relative thresholds, k-means and Bayesian clustering, and a self-adaptive configuration (SAC) of k-means and Bayesian was applied. Three state-of-the-art deep learning-based segmentations methods using a 3D U-Net architecture were also applied. One was semiautomatic and two were fully automatic, of which one is publicly available. Dice coefficient (DC) measured segmentation overlap, considering manual segmentation the ground truth. Lymphoma lesions were characterized by 31 features. Intraclass correlation coefficient (ICC) assessed features agreement between different segmentation methods. Nine hundred twenty [18F]FDG-avid lesions were identified. The SAC Bayesian method achieved the highest median intra-observer DC (0.87). Inter-observers' DC was higher for SAC Bayesian than manual segmentation (0.94 vs 0.84, p < 0.001). Semiautomatic deep learning-based median DC was promising (0.83 (Obs1), 0.79 (Obs2)). Threshold-based methods and publicly available 3D U-Net gave poorer results (0.56 ≤ DC ≤ 0.68). Maximum, mean, and peak standardized uptake values, metabolic tumor volume, and total lesion glycolysis showed excellent agreement (ICC ≥ 0.92) between manual and SAC Bayesian segmentation methods. The SAC Bayesian classifier is more reproducible and produces similar lesion features compared to manual segmentation, giving the best concordant results of all other methods. Deep learning-based segmentation can achieve overall good segmentation results but failed in few patients impacting patients' clinical evaluation.

Abstract
The treatment of multiple myeloma has profoundly changed with the introduction of several innovative therapies. The optimization of therapeutic sequencing through the combined use of the various drugs developed in recent years and the attention given to the characteristics of patients have allowed the reduction of toxicities and increased survival and quality of life of patients with multiple myeloma. These treatment recommendations from the Portuguese Multiple Myeloma Group offer guidance for first-line treatment and progression/relapse situations. These recommendations are given highlighting the data that justify each choice and referring to the respective levels of evidence that support these options. Whenever possible, the respective national regulatory framework is presented. These recommendations constitute an advance towards the best treatment of multiple myeloma in Portugal.

Abstract
Systemic light-chain (AL) amyloidosis is a rare and debilitating disease. Advances have been made in new treatments in recent years, yet real-world data on the management of the disease are scarce. EMN23 is a retrospective, observational study of patients who initiated first-line treatment in 2004-2018 in Europe, presenting the demographics, clinical characteristics, treatment patterns, and outcomes, from 4480 patients. Regimens based on bortezomib were the most frequently used as first-line therapy; only 6.2% of the patients received autologous stem cell transplant. Hematologic responses improved post-2010 (67.1% vs 55.6% pre-2010). The median overall survival (OS) was 48.8 (45.2-51.7) months; 51.4 (47.3-57.7) months pre-2010 and 46.7 (41.3-52.2) months post-2010. Early mortality was 13.4% and did not improve (11.4% vs 14.4% pre- and post-2010); furthermore, it remained high in patients with advanced cardiac disease (over 39% for stage IIIb). There was a significant improvement for stage IIIa (14.2 vs 30.7 months, p = 0.0170) but no improvement for stage IIIb patients (5.0 vs 4.5 months). This European real-world study of AL-amyloidosis emphasizes the unmet needs of early diagnosis, and the lack of improvement in survival outcomes of the frail stage IIIb population, despite the introduction of new therapies in recent years.

Abstract
Bruton's tyrosine kinase (BTK) is a member of the TEC-family kinases and crucial for the proliferation and differentiation of B-cells. We evaluated the therapeutic potential of a covalent inhibitor (JS25) with nanomolar potency against BTK and with a more desirable selectivity and inhibitory profile compared to the FDA-approved BTK inhibitors ibrutinib and acalabrutinib. Structural prediction of the BTK/JS25 complex revealed sequestration of Tyr551 that leads to BTK's inactivation. JS25 also inhibited the proliferation of myeloid and lymphoid B-cell cancer cell lines. Its therapeutic potential was further tested against ibrutinib in preclinical models of B-cell cancers. JS25 treatment induced a more pronounced cell death in a murine xenograft model of Burkitt's lymphoma, causing a 30-40% reduction of the subcutaneous tumor and an overall reduction in the percentage of metastasis and secondary tumor formation. In a patient model of diffuse large B-cell lymphoma, the drug response of JS25 was higher than that of ibrutinib, leading to a 64% "on-target" efficacy. Finally, in zebrafish patient-derived xenografts of chronic lymphocytic leukemia, JS25 was faster and more effective in decreasing tumor burden, producing superior therapeutic effects compared to ibrutinib. We expect JS25 to become therapeutically relevant as a BTK inhibitor and to find applications in the treatment of hematological cancers and other pathologies with unmet clinical treatment.

Abstract
Patients with lymphoproliferative diseases are at an increased risk of an incomplete immune response following vaccination or SARS‐CoV‐2 infection and might develop persistent viral infection and severe COVID‐19 disease. We present a case of successful treatment of persistent and mechanical‐ventilation‐requiring SARS‐CoV‐2 infection in a del17+ CLL patient using exogenous antibodies. Patients with chronic lymphocytic leukemia (CLL) might have an incomplete immune response following vaccination or SARS‐CoV‐2 infection. There is therapeutic potential of monoclonal antibodies in persistent and severe COVID‐19, mirrored in a CLL patient.

Abstract
Despite the wide variety of existing therapies, multiple myeloma (MM) remains a disease with dismal prognosis. Choosing the right treatment for each patient remains one of the major challenges. A new approach being explored is the use of ex vivo models for personalized medicine. Two-dimensional culture or animal models often fail to predict clinical outcomes. Three-dimensional ex vivo models using patients' bone marrow (BM) cells may better reproduce the complexity and heterogeneity of the BM microenvironment. Here, we review the strengths and limitations of currently existing patient-derived ex vivo three-dimensional MM models. We analyze their biochemical and biophysical properties, molecular and cellular characteristics, as well as their potential for drug testing and identification of disease biomarkers. Furthermore, we discuss the remaining challenges and give some insight on how to achieve a more biomimetic and accurate MM BM model. Overall, there is still a need for standardized culture methods and refined readout techniques. Including both myeloma and other cells of the BM microenvironment in a simple and reproducible three-dimensional scaffold is the key to faithfully mapping and examining the relationship between these players in MM. This will allow a patient-personalized profile, providing a powerful tool for clinical and research applications.

Abstract
Multiple myeloma (MM), the third most frequent hematological cancer worldwide, is characterized by the proliferation of neoplastic plasma cells in the bone marrow (BM). One of the hallmarks of MM is a permissive BM microenvironment. Increasing evidence suggests that cell-to-cell communication between myeloma and immune cells via tumor cell-derived extracellular vesicles (EV) plays a key role in the pathogenesis of MM. Hence, we aimed to explore BM immune alterations induced by MM-derived EV. For this, we inoculated immunocompetent BALB/cByJ mice with a myeloma cell line, MOPC315.BM, inducing a MM phenotype. Upon tumor establishment, characterization of the BM microenvironment revealed the expression of both activation and suppressive markers by lymphocytes, such as granzyme B and PD-1, respectively. In addition, conditioning of the animals with MOPC315.BM-derived EV, before transplantation of the MOPC315.BM tumor cells, did not anticipate the disease phenotype. However, it induced features of suppression in the BM milieu, such as an increase in PD-1 expression by CD4+ T cells. Overall, our findings reveal the involvement of MOPC315.BM-derived EV protein content as promoters of immune niche remodeling, strengthening the importance of assessing the mechanisms by which MM may impact the immune microenvironment.

Abstract
Multiple myeloma (MM) is a hematological malignancy of clonal antibody–secreting plasma cells (PCs). MM diagnosis and risk stratification rely on bone marrow (BM) biopsy, an invasive procedure prone to sample bias. Liquid biopsies, such as extracellular vesicles (EV) in peripheral blood (PB), hold promise as new minimally invasive tools. Real-world studies analyzing patient-derived EV proteome are rare. Here, we characterized a small EV protein content from PB and BM samples in a cohort of 102 monoclonal gammopathies patients routinely followed in the clinic and 223 PB and 111 BM samples were included. We investigated whether EV protein and particle concentration could predict an MM patient prognosis. We found that a high EV protein/particle ratio, or EV cargo >0.6 µg/108 particles, is related to poorer survival and immune dysfunction. These results were supported at the protein level by mass spectrometry. We report a set of PB EV-proteins (PDIA3, C4BPA, BTN1A1, and TNFSF13) with a new biomarker potential for myeloma patient outcomes. The high proteomic similarity between PB and BM matched pairs supports the use of circulating EV as a counterpart of the BM EV proteome. Overall, we found that the EV protein content is related to patient outcomes, such as survival, immune dysfunction, and possibly treatment response.

Abstract
BACKGROUND Multiple myeloma (MM) is the second most common hematological cancer worldwide and has significant morbidity and mortality and is increasing in incidence. While MM management costs are considerable, specific economic data at the country level remain scarce. OBJECTIVE This study assesses the burden and cost of MM in Portugal from the perspective of the National Health Service (NHS) to support the definition of health policies, resource allocation and patient care. METHODS Developed by the Portuguese Multiple Myeloma Group, this study considers the most recent available data. Burden of disease was measured using disability-adjusted life-years (DALYs). The cost of MM was estimated using a prevalence-based model that estimated direct costs for the NHS considering all costs associated with diagnosis, hospitalizations, surgeries, emergency visits, medical appointments, drugs and transportation. Costs were quantified based on the diagnosis-related group funding price, except for drug usage, which was calculated using the average hospital product stock price. RESULTS The burden of disease attributable to MM for 2018 was estimated at 8931 DALYs: 8570 resulting from premature deaths and 361 from disability. Average yearly direct costs per patients with MM amounted to €31,449 (year 2018 values). Total direct costs are estimated at €61 million per year. CONCLUSIONS The mortality rate in MM means that most DALYs are due to years of life lost rather than years lost due to disability. This study generates comprehensive data on the burden and cost of MM in Portugal and provides updated insights into the costs associated with the management of MM.

Abstract
Despite the improvement of patient's outcome obtained by the current use of immunomodulatory drugs, proteasome inhibitors or anti-CD38 monoclonal antibodies, multiple myeloma (MM) remains an incurable disease. More recently, the testing in clinical trials of novel drugs such as anti-BCMA CAR-T cells, antibody-drug conjugates or bispecific antibodies broadened the possibility of improving patients' survival. However, thus far, these treatment strategies have not been able to steadily eliminate all malignant cells, and the aim has been to induce a long-term complete response with minimal residual disease (MRD)-negative status. In this sense, approaches that target not only myeloma cells but also the surrounding microenvironment are promising strategies to achieve a sustained MRD negativity with prolonged survival. This review provides an overview of current and future strategies used for immunomodulation of MM focusing on the impact on bone marrow (BM) immunome.

Abstract
The management of older patients with Multiple Myeloma (MM) is particularly challenging due to the highly heterogeneous nature of this population, both in terms of physical and cognitive functioning. Older patients may be divided into fit, intermediate and frail, with variable abilities to tolerate treatments. A careful and correct assessment of the frailty status is thus paramount for the success of therapy and for improving outcomes. With the aging of the European population, the number of older patients with MM is rapidly growing. We hereby present the deliberations and recommendations from an expert panel of Portuguese hematologists conducted to discuss the management of this population, including how to stratify and treat older patients with MM according to their frailty status. The use of frailty tools is critical for the development of individualized risk-adapted treatment strategies and to minimize the risk of under or overtreatment. Aggressive therapies should be used in fitter patients to improve survival outcomes, while frail patients should generally be treated with less toxic approaches to control symptoms while minimizing toxicity. In intermediate-fit patients, low-dose triplets are recommended to achieve a balance between improving survival and maintaining quality of life. The management of older patients with MM should be performed by a multidisciplinary team in view of their advanced age and high prevalence of comorbidities. The inclusion of older and frail patients in future clinical trials investigating treatment regimens for MM is crucial to evaluate treatment feasibility and to improve clinical decision making in this population.

Abstract
Multiple myeloma (MM) is a challenging, progressive, and highly heterogeneous hematological malignancy. MM is characterized by multifocal proliferation of neoplastic plasma cells in the bone marrow (BM) and sometimes in extramedullary organs. Despite the availability of novel drugs and the longer median overall survival, some patients survive more than 10 years while others die rapidly. This heterogeneity is mainly driven by biological characteristics of MM cells, including genetic abnormalities. Disease progressions are mainly due to the inability of drugs to overcome refractory disease and inevitable drug-resistant relapse. In clinical practice, a bone marrow biopsy, mostly performed in one site, is still used to access the genetics of MM. However, BM biopsy use is limited by its invasive nature and by often not accurately reflecting the mutational profile of MM. Recent insights into the genetic landscape of MM provide a valuable opportunity to implement precision medicine approaches aiming to enable better patient profiling and selection of targeted therapies. In this review, we explore the use of the emerging field of liquid biopsies in myeloma patients considering current unmet medical needs, such as assessing the dynamic mutational landscape of myeloma, early predictors of treatment response, and a less invasive response monitoring.

Abstract
Background Whole-body diffusion weighted imaging (WB-DWI) has proven value to detect multiple myeloma (MM) lesions. However, the large volume of imaging data and the presence of numerous lesions makes the reading process challenging. The aim of the current study was to develop a semi-automatic lesion segmentation algorithm for WB-DWI images in MM patients and to evaluate this smart-algorithm (SA) performance by comparing it to the manual segmentations performed by radiologists. Methods An atlas-based segmentation was developed to remove the high-signal intensity normal tissues on WB-DWI and to restrict the lesion area to the skeleton. Then, an outlier threshold-based segmentation was applied to WB-DWI images, and the segmented area’s signal intensity was compared to the average signal intensity of a low-fat muscle on T1-weighted images. This method was validated in 22 whole-body DWI images of patients diagnosed with MM. Dice similarity coefficient (DSC), sensitivity and positive predictive value (PPV) were computed to evaluate the SA performance against the gold standard (GS) and to compare with the radiologists. A non-parametric Wilcoxon test was also performed. Apparent diffusion coefficient (ADC) histogram metrics and lesion volume were extracted for the GS segmentation and for the correctly identified lesions by SA and their correlation was assessed. Results The mean inter-radiologists DSC was 0.323 ± 0.268. The SA vs GS achieved a DSC of 0.274 ± 0.227, sensitivity of 0.764 ± 0.276 and PPV 0.217 ± 0.207. Its distribution was not significantly different from the mean DSC of inter-radiologist segmentation (p = 0.108, Wilcoxon test). ADC and lesion volume intraclass correlation coefficient (ICC) of the GS and of the correctly identified lesions by the SA was 0.996 for the median and 0.894 for the lesion volume (p < 0.001). The duration of the lesion volume segmentation by the SA was, on average, 10.22 ± 0.86 min, per patient. Conclusions The SA provides equally reproducible segmentation results when compared to the manual segmentation of radiologists. Thus, the proposed method offers robust and efficient segmentation of MM lesions on WB-DWI. This method may aid accurate assessment of tumor burden and therefore provide insights to treatment response assessment.

Abstract
The immunoregulatory and anti-infective properties of normal circulating polyclonal Abs have been exploited for the therapeutic purposes in the form of IVIG as well as several hyperimmune globulins. Current knowledge on the therapeutic use of normal Igs is based on the discoveries made by several pioneers of the field. In this paper, we review the evolution of IVIG over the years. More importantly, the process started as an s.c. replacement in γ globulin-deficient patients, underwent metamorphosis into i.m. Ig, was followed by IVIG, and is now back to s.c. forms. Following successful use of IVIG in immune thrombocytopenic purpura, there has been an explosion in the therapeutic applications of IVIG in diverse autoimmune and inflammatory conditions. In addition to clinically approved pathological conditions, IVIG has been used as an off-label drug in more than 100 different indications. The current worldwide consumption of IVIG is over 100 tons per year.

Abstract
Leber inherited optic neuropathy (LHON) is characterized by subacute bilateral loss of central vision due to dysfunction and loss of retinal ganglion cells (RGCs). Comprehensive visual electrophysiological investigations (including pattern reversal visual evoked potentials, pattern electroretinography and the photopic negative response) performed on 13 patients with acute and chronic LHON indicate early impairment of RGC cell body function and severe axonal dysfunction. Temporal, spatial and chromatic psychophysical tests performed on 7 patients with acute LHON and 4 patients with chronic LHON suggest severe involvement or loss of the midget, parasol and bistratified RGCs associated with all three principal visual pathways.

Abstract
Patients with multiple myeloma (MM) and severe renal impairment (SRI) have shorter survival than MM patients without renal failure. Although lenalidomide is a highly active drug, this immunomodulatory agent is frequently neglected in this context due to its predominant renal clearance and, consequently, an increased risk of toxicity. This risk might be overcome with the proper lenalidomide dose adjustment to renal function. This study evaluates the outcomes of 23 relapsed MM patients with SRI (baseline creatinine clearance (CrCl) <30 mL/min) treated with lenalidomide-dexamethasone (LenDex), including 56 % (13 patients) under hemodialysis. The median CrCl at start of LenDex was 19 mL/min; an overall response rate (partial response or better) of 56 % was obtained, with a median follow-up from start of LenDex of 52 months (8-79). The median time until maximal response was 4 months, and in 58 % (7/12), the response was longer than 2 years. Nine percent had renal improvement, but all the 13 patients on hemodialysis remained under treatment. LenDex was interrupted in three cases because of adverse events (infections and cutaneous events); 78 % of the patients were on thromboprophylaxis with aspirin. It is important to notice that, after initial dose adjustment of therapy, there should be a continuous process of dose adjustment, taking into account variations in renal function. Furthermore, lenalidomide dose adjustment should be made according to the individual tolerance, even with stable renal function. LenDex dose adjustment, according to these principles, does not negatively impact response and improves treatment tolerance. It has a clear potential to treat this group of patients and to induce long duration of responses [event-free survival (EFS) 20.5 m and overall survival (OS) 42.6 m].

Abstract
Lenalidomide was approved for the treatment of relapsed and refractory multiple myeloma (rrMM) based on MM009 and MM010 clinical trials. However, its effectiveness and safety profile in real clinical practice should be further assessed. We retrospectively evaluated 90 consecutive patients treated in our center with lenalidomide and dexamethasone (LenDex) between 2007 and 2012. The overall response rate to this treatment was 68 % and the median duration of response was 13.6 months. Patients treated in first relapse and those treated with LenDex longer than 1 year achieved the best responses. Cytogenetics was associated with PFS and best response to treatment was the only variable associated with longer PFS and OS in univariate and multivariate analyses. Our analysis confirmed that LenDex is effective in rrMM patient, well tolerated, and applicable to the majority of patients outside clinical trials; patients achieving a complete response, even in the context of relapse, have a longer survival; quality of response is better when lenalidomide is used in second line than later on and it is a good surrogate marker for OS. Accordingly, CR should be aimed in the rrMM setting, especially in fit patients. Previous treatment with thalidomide should not hamper the option for lenalidomide therapy.

Abstract
Key Clinical Message The survival of multiple myeloma patients has improved very significantly over the last decade. Still median overall survival is inferior to 5 years. A small proportion of patients survive longer than 10 years. In this paper we discuss four cases illustrating the nonhomogeneous clinical presentation and evolution of this subset of patients. Surprisingly, these long survivors do not always have deep responses and some require frequent treatments, which include autologous stem cell transplantation and novel drugs. The authors discuss several aspects of these clinical histories, including treatment options, raising hypothesis on their relation with long survivorship which may be important to have in consideration when studying this subject.

Abstract
PURPOSE [corrected] After autologous stem cell transplantation (ASCT) the immunological B cell compartment recovers slowly. Delays on the recovery of B cell function after autologous stem cell transplantation are due to the low lymphocytes count and to their intrinsic dysfunction. METHODS We studied the in vivo B cell reconstitution after ASCT examining the independent effect of polyclonal IgG (PolyIg), Fab or Fc fragments infusions in a murine animal model during a period of 12 weeks. These molecules were used in low doses, mimicking the recommended use of IVIg in the case of hypogammaglobulinemia in humans. Flow cytometry analysis and ELISA tests were conducted to monitor the reconstitution of B cells and serum immunoglobulin production. Panama blot and PCA factor 1 analysis were used to study the kinetics of immunoglobulin repertoires reconstitution. Mechanistic studies were also performed using in vitro cell culture. RESULTS During follow-up after ASCT, peripheral B cells expand independently of treatment, correcting the immediate increase in sBAFF (soluble B cell activating factor) induced by previous intense myeloablation. Treatments with Fab and Fc fragments infusions promote significant IgM and IgG production comparing to control. Although the complete recovery of antibody repertoire is only achieved at the end of follow-up after ASCT, there is an earlier and significantly stronger recovery in the treated mice, which is evident at 9 weeks after ASCT. At 30 weeks after ASCT, normal values of antibody repertoire were detected in all individuals. Mechanistic studies show that Fab and Fc fragments promote IgG1 production by indirect pathways. CONCLUSIONS The results presented here demonstrate that polyclonal immunoglobulin indirectly improves the function of the reconstituted B cells and their IgG production by means of Fc-mediated effects on bystander cells. These results further stimulate the discussion about the advantages of IVIg therapy during immune reconstitution after human ASCT.

Abstract
Paradoxically, human B cell immune deficiencies are associated with increased susceptibility to viral and fungi infections, which are T cell immunity related infections. Also, some viral infections occurring in immune depressed patients such as cytomegalovirus infections are recommended to be treated with intravenous immunoglobulin (IVIg) in combination with antiviral therapy. This fact has no clear biological explanation but it has been shown to be successful. Recently, B cells and immunoglobulin were identified as essential elements driving T cell receptor (TCR) diversity generation. Idiotype peptides of B cell immunoglobulin may be the driving force for the antigen presenting function of B cells and other antigen presenting cells to influence the T cell repertoire. This seems to be another relevance of Jerne's idiotypic network and another function of immunoglobulin. Since T cells function depends on the diversity of the TCR repertoire, means to increase the diversity of the T cell repertoire may improve T cell function in situations characterized by a contracted TCR repertoire, such as AIDS, primary immunodeficiency, cancer, autoimmunity and following chemotherapy and hematopoietic precursors transplantation. The clinical hypothesis here put forward is that B cells and/or immunoglobulin may be used therapeutically aiming to increase and potentially to restore T cell repertoire diversity improving T cell function in situations implicating a contracted T cell repertoire. The fact that immunoglobulin influence the composition of T cell repertoire by increasing its diversity allows a much wider application of this molecule in the clinical practice. Here is presented a novel reasoning for the use of IVIg in humans, which should be explored. All the situations where immune reconstitution occurs are potentially a target for this therapeutically mechanism, aiming to fast and improve the diversity of the reconstituted immune repertoires. This new role of Ig molecule, an old and widely therapeutically used molecule, may help to explain several effects that IVIg have in the T cell compartment, such as modulation of the activation and function of effectors T cells. The idea that immunoglobulin is essential in the generation and maintenance of a diverse compartment of T cells, affecting T cell function via that mechanism suggests a promising approach to medical conditions involving immune reconstitution. Furthermore, it represents a new paradigm of understanding the immune system as a complex, interdependent web of cells/cell products that inter-affect each other generation, function and survival.

Abstract
AIMS To analyse the possible activation of distinct molecular pathways in mucosa-associated lymphoid tissue (MALT) lymphoma, we determined the prevalence of trisomies 3, 12, 18 in MALT lymphomas from different organs, as well as the prevalence of translocations of the MALT1 gene in a subset of primary breast MALT lymphomas. We compared the numerical cytogenetic alterations in lymphomas, precursor lesions and in normal non-haematolymphoid tissue from the same organs. METHODS AND RESULTS Forty-two samples of paraffin-embedded tissue (29 MALT lymphomas from stomach, breast, parotid and thyroid; two Sjögren's syndrome; two Hashimoto's thyroiditis and nine reactive samples) were studied by fluorescence in situ hybridization (FISH). Analysed together, the cases of gastric, parotid and thyroid MALT lymphomas presented trisomy 3 in 46%, trisomy 12 in 28% and trisomy 18 in 21% of the cases. In contrast to other locations, trisomy 3 was not present in the majority of the cases of primary breast MALT lymphomas. None of the nine breast cases presented MALT1 gene rearrangements. Half of the cases of preneoplastic lesions exhibited trisomy 3 and trisomy 12; none exhibited trisomy 18. CONCLUSIONS Trisomy 3 is the most frequent numerical abnormality in gastric, parotid and thyroid but not in primary breast MALT lymphomas. MALT1 gene rearrangements are also rare in this location, suggesting that distinct molecular pathways may be activated in breast cases.

Abstract
It is generally accepted in immunology that while T and B cells collaborate for the production of antibodies in response to protein antigens, T cells develop and function in the absence of B cells. However, B cell-deficient subjects and mice have unexplained cellular immune defects. Here, we examined the contribution of B cells/Ig to the generation of diversity and function of T cells. Mice lacking B cells and Ig (JH(-/-)) or having oligoclonal B cells (QM) had a profoundly contracted T cell receptor (TCR) Vbeta repertoire: 0.08 and 1.3% of wild type, respectively. Rejection of H-Y-incompatible skin grafts in QM and JH(-/-) mice was significantly delayed (median, 43 and 22 days, respectively) compared to wild-type mice (median, 16 days). Furthermore, reduction of the TCR Vbeta diversity by thymectomy in wild-type mice significantly increased survival of H-Y-incompatible skin grafts, and reconstitution of the T cell diversity in QM mice with Ig Fab fragments significantly decreased survival of the skin grafts. These results indicate that B cells and/or Ig "help" T cells through the generation and maintenance of T cell diversity, improving T cell function. Our results may have important implications for therapy and immune reconstitution in the context of AIDS, cancer, autoimmunity and post-myeloablative treatments.

Abstract
T cell diversity was once thought to depend on the interaction of T cell precursors with thymic epithelial cells. Recent evidence suggests, however, that diversity might arise through the interaction of developing T cells with other cells, the identity of which is not known. In this study we show that T cell diversity is driven by B cells and Ig. The TCR V beta diversity of thymocytes in mice that lack B cells and Ig is reduced to 6 x 10(2) from wild-type values of 1.1 x 10(8); in mice with oligoclonal B cells, the TCR V beta diversity of thymocytes is 0.01% that in wild-type mice. Adoptive transfer of diverse B cells or administration of polyclonal Ig increases thymocyte diversity in mice that lack B cells 8- and 7-fold, respectively, whereas adoptive transfer of monoclonal B cells or monoclonal Ig does not. These findings reveal a heretofore unrecognized and vital function of B cells and Ig for generation of T cell diversity and suggest a potential approach to immune reconstitution.
