    Reduced intensity conditioning increases risk of severe cGVHD: identification of risk factors for cGVHD in a multicenter setting2018In: Medical Oncology, ISSN 1357-0560, E-ISSN 1559-131X, Vol. 35, no 6, article id 79Article in journal (Refereed)
    Abstract [en]

    Chronic graft-versus-host disease (cGVHD) remains a major cause of morbidity and mortality after allogeneic hematopoietic stem cell transplantation (HSCT). Aim is to identify risk factors for the development of cGVHD in a multicenter setting. Patients transplanted between 2000 and 2006 were analyzed (n = 820). Donors were HLA-identical siblings (57%), matched unrelated donors (30%), and HLA-A, B or DR antigen mismatched (13%). Reduced intensity conditioning (RIC) was given to 65% of patients. Overall incidence of cGVHD was 46% for patients surviving more than 100 days after HSCT (n = 747). Older patient age [HR 1.15, p < 0.001], prior acute GVHD [1.30, p = 0.024], and RIC [1.36, p = 0.028] increased overall cGVHD. In addition, RIC [4.85, p < 0.001], prior aGVHD [2.14, p = 0.001] and female donor to male recipient [1.80, p = 0.008] increased the risk of severe cGVHD. ATG had a protective effect for both overall [0.41, p < 0.001] and severe cGVHD [0.20, p < 0.001]. Relapse-free survival (RFS) was impaired in patients with severe cGVHD. RIC, prior aGVHD, and female-to-male donation increase the risk of severe cGVHD. ATG reduces the risk of all grades of cGVHD without hampering RFS. GVHD prophylaxis may be tailored according to the risk profile of patients.

    Highly similar genomic landscapes in monoclonal B-cell lymphocytosis and ultra-stable chronic lymphocytic leukemia with low frequency of driver mutations2018In: Haematologica, ISSN 0390-6078, E-ISSN 1592-8721, Vol. 103, no 5, p. 865-873Article in journal (Refereed)
    Abstract [en]

    Despite the recent discovery of recurrent driver mutations in chronic lymphocytic leukemia, the genetic factors involved in disease onset remain largely unknown. To address this issue, we per-formed whole-genome sequencing in 11 individuals with monoclonal B-cell lymphocytosis, both of the low-count and high-count subtypes, and 5 patients with ultra-stable chronic lymphocytic leukemia (>10 years without progression from initial diagnosis). All three entities were indistinguishable at the genomic level exhibiting low genomic complexity and similar types of somatic mutations. Exonic mutations were not frequently identified in putative chronic lymphocytic leukemia driver genes in all settings, including low-count monoclonal B-cell lymphocytosis. To corroborate these findings, we also performed deep sequencing in 11 known frequently mutated genes in an extended cohort of 28 monoclonal B-cell lym phocytosis/chronic lymphocytic leukemia cases. Interestingly, shared mutations were detected between clonal B cells and paired polymorphonuclear cells, strengthening the notion that at least a fraction of somatic mutations may occur before disease onset, likely at the hematopoietic stem cell level. Finally, we identified previously unreported non-coding variants targeting pathways relevant to B-cell and chronic lymphocytic leukemia development, likely associated with the acquisition of the characteristic neoplastic phenotype typical of both monoclonal B-cell lymphocytosis and chronic lymphocytic leukemia.

    Stereotyped B-cell receptors in chronic lymphocytic leukemia2014In: Leukemia and Lymphoma, ISSN 1042-8194, E-ISSN 1029-2403, Vol. 55, no 10, p. 2252-2261Article, review/survey (Refereed)
    Abstract [en]

    Over the last decade, immunogenetic analysis of B-cell receptor immunoglobulins (BcR IGs) has proved to be a particularly fruitful field in chronic lymphocytic leukemia (CLL), not only for understanding disease pathogenesis but also for discriminating clinical subgroups with markedly distinct course and outcome. Of utmost importance was the identification of quasi-identical BcR IGs among unrelated patients with CLL, fittingly coined as "stereotypy," that set the wheels in motion for unraveling the role of antigen(s) in the selection and expansion of the leukemic clones. The categorization of CLL clones into "subsets" according to shared BcR IG structural characteristics provided a compartmentalized view of this otherwise heterogeneous disease, which eventually led to defining strikingly homogeneous groups of patients in terms of: (i) functional properties of the clonal BcR IGs, e. g. BcR reactivity and signaling; (ii) clonal genetic landscape, e. g. genomic aberrations, gene expression/methylation profiles, microRNA signatures; and (iii) clinical course and outcome. The remarkable restriction of the CLL IG gene repertoire, resulting to a great degree from the high impact of BcR IG stereotypy, may also prompt speculations regarding CLL ontogenesis. Overall, the BcR IG molecule justifiably lies at the heart of CLL clinical research, holding the promise of subset-tailored therapies.

    Lenalidomide-bendamustine-rituximab in patients older than 65 years with untreated mantle cell lymphoma2016In: Blood, ISSN 0006-4971, E-ISSN 1528-0020, Vol. 128, no 14, p. 1814-1820Article in journal (Refereed)
    Abstract [en]

    For elderly patients with mantle cell lymphoma (MCL), there is no defined standard therapy. In this multicenter, open-label phase 1/2 trial, we evaluated the addition of lenalidomide (LEN) to rituximab-bendamustine (R-B) as first-line treatment for elderly patients with MCL. Patients >65 years with untreated MCL, stages II-IV were eligible for inclusion. Primary end points were maximally tolerable dose (MTD) of LEN and progression-free survival (PFS). Patients received 6 cycles every four weeks of L-B-R (L D1-14, B 90 mg/m(2) IV, days 1-2 and R 375 mg/m(2) IV, day 1) followed by single LEN (days 1-21, every four weeks, cycles 7-13). Fifty-one patients (median age 71 years) were enrolled from 2009 to 2013. In phase 1, the MTD of LEN was defined as 10 mg in cycles 2 through 6, and omitted in cycle 1. After 6 cycles, the complete remission rate (CRR) was 64%, and 36% were MRD negative. At a median follow-up time of 31 months, median PFS was 42 months and 3-year overall survival was 73%. Infection was the most common nonhematologic grade 3 to 5 event and occurred in 21 (42%) patients. Opportunistic infections occurred in 3 patients: 2 Pneumocystis carinii pneumonia and 1 cytomegalovirus retinitis. Second primary malignancies (SPM) were observed in 8 patients (16%). LEN could safely be combined with R-B when added from the second cycle in patients with MCL, and was associated with a high rate of CR and molecular remission. However, we observed a high degree of severe infections and an unexpected high number of SPMs, which may limit its use. This trial is registered at www.Clinicaltrials.gov as #NCT00963534.

    Anti-leukaemic effects induced by APR-246 are dependent on induction of oxidative stress and the NFE2L2/HMOX1 axis that can be targeted by PI3K and mTOR inhibitors in acute myeloid leukaemia cells2016In: British Journal of Haematology, ISSN 0007-1048, E-ISSN 1365-2141, Vol. 174, no 1, p. 117-126Article in journal (Refereed)
    Abstract [en]

    The small molecule APR-246 (PRIMA-1(MET)) is a novel drug that restores the activity of mutated and unfolded TP53 protein. However, the mechanisms of action and potential off-target effects are not fully understood. Gene expression profiling in TP53 mutant KMB3 acute myeloid leukaemia (AML) cells showed that genes which protected cells from oxidative stress to be the most up-regulated. APR-246 exposure also induced reactive oxygen species (ROS) formation and depleted glutathione in AML cells. The genes most up-regulated by APR-246, confirmed by quantitative real time polymerase chain reaction, were heme oxygenase-1 (HMOX1, also termed HO-1), SLC7A11 and RIT1. Up-regulation of HMOX1, a key regulator of cellular response to ROS, was independent of TP53 mutational status. NFE2L2 (also termed Nrf2), a master regulator of HMOX1 expression, showed transcriptional up-regulation and nuclear translocation by APR-246. Down-regulation of NFE2L2 by siRNA in AML cells significantly increased the antitumoural effects of APR-246. The PI3K inhibitor wortmannin and the mTOR inhibitor rapamycin inhibited APR-246-induced nuclear translocation of NFE2L2 and counteracted the protective cellular responses to APR-246, resulting in synergistic cell killing together with APR-246. In conclusion, ROS induction is important for antileukaemic activities of APR-246 and inhibiting the protective response of the Nrf-2/HMOX1 axis using PI3K inhibitors, enhances the antileukaemic effects.

    Circulating YKL-40 in patients with essential thrombocythemia and polycythemia vera treated with the novel histone deacetylase inhibitor vorinostat2014In: Leukemia research: a Forum for Studies on Leukemia and Normal Hemopoiesis, ISSN 0145-2126, E-ISSN 1873-5835, Vol. 38, no 7, p. 816-821Article in journal (Refereed)
    Abstract [en]

    YKL-40 regulates vascular endothelial growth factors and induces tumor proliferation. We investigated YKL-40 before and after treatment with vorinostat in 31 polycythemia vera (PV) and 16 essential thrombocythemia (ET) patients. Baseline PV patient levels were 2 times higher than in healthy controls (P<0.0001) and 1.7 times higher than in ET (P = 0.02). A significant correlation between YKL-40 at baseline and neutrophils, CRP, LDH, JAK2V617F and platelets in PV patients was observed, as well as a significantly greater reduction of YKL-40 levels in PV patients responding to therapy. YKL-40 might be a novel marker of disease burden and progression in myeloproliferative neoplasms. (C) 2014 Elsevier Ltd. All rights reserved.

    Methods for individualising factor VIII dosing in prophylaxis2014In: European Journal of Haematology, ISSN 0902-4441, E-ISSN 1600-0609, Vol. 93, p. 16-20Article, review/survey (Refereed)
    Abstract [en]

    Haemophilia A is a sex-linked disorder characterised chiefly by recurrent, spontaneous joint and muscle bleedings resulting from deficiency of factor VIII (FVIII). Recurrent joint bleeds result in haemophilic arthropathy. Unless treated with factor replacement therapy, many patients with severe haemophilia become disabled. The first clinical evidence favouring prophylaxis originated from the studies in Sweden and the Netherlands in the 1960s. Later on, it was shown that prophylaxis could prevent arthropathy, if started early in life, or slow its progression in adults with established arthropathy. The optimal dosing of FVIII in long-term prophylaxis has still not been determined, and there is growing evidence that the dose and frequency of FVIII should be individualised. We conducted a systematic search of PubMed to identify all relevant articles on FVIII prophylaxis in severe haemophilia A. We focused on articles with detailed information about individualisation of prophylaxis. Long-term prophylaxis in haemophilia was introduced in Sweden in the late 1950s. However, standard prophylactic regimens may not be appropriate for all patients with severe haemophilia. Factors such as age, joint status, co-morbidities and differences in pharmacokinetics lead to interindividual variation in factor requirement. Dose tailoring of FVIII by clinical outcome was first described in 1994. Since then, several dose-finding studies questioned the necessity to maintain preinfusion levels of FVIII above 1%. Individualising prophylaxis by dose tailoring is now recommended. Each country should adopt policies for individualising prophylaxis in patients with severe haemophilia. This would lead to a better distribution of the available source of factor concentrates.

    Clinical risks and healthcare utilization of hematopoietic cell transplantation for sickle cell disease in the USA using merged databases2017In: Haematologica, ISSN 0390-6078, E-ISSN 1592-8721, Vol. 102, no 11, p. 1823-1832Article in journal (Refereed)
    Abstract [en]

    Advances in allogeneic hematopoietic cell transplantation for sickle cell disease have improved outcomes, but there is limited analysis of healthcare utilization in this setting. We hypothesized that, compared to late transplantation, early transplantation (at age < 10 years) improves outcomes and decreases healthcare utilization. We performed a retrospective study of children transplanted for sickle cell disease in the USA during 2000-2013 using two large databases. Univariate and Cox models were used to estimate associations of demographics, sickle cell disease severity, and transplant-related variables with mortality and chronic graft-versus-host disease, while Wilcoxon, Kruskal-Wallis, or linear trend tests were applied for the estimates of healthcare utilization. Among 161 patients with a 2-year overall survival rate of 90% (95% confidence interval [CI] 85-95%) mortality was significantly higher in those who underwent late transplantation versus early (hazard ratio (HR) 21, 95% CI 2.8-160.8, P=0.003) and unrelated compared to matched sibling donor transplantation (HR 5.9, 95% CI 1.7-20.2, P=0.005). Chronic graftversus host disease was significantly more frequent among those translanted late (HR 1.9, 95% CI 1.0-3.5, P=0.034) and those who received an unrelated graft (HR 2.5, 95% CI 1.2-5.4; P=0.017). Merged data for 176 patients showed that the median total adjusted transplant cost per patient was $467,747 (range: $344,029-$ 799,219). Healthcare utilization was lower among recipients of matched sibling donor grafts and those with low severity disease compared to those with other types of donor and disease severity types (P<0.001 and P=0.022, respectively); no association was demonstrated with late transplantation (P=0.775). Among patients with 2-year pre-and post-transplant data (n=41), early transplantation was associated with significant reductions in admissions (P<0.001), length of stay (P<0.001), and cost (P=0.008). Early transplant outcomes need to be studied prospectively in young children without severe disease and an available matched sibling to provide conclusive evidence for the superiority of this approach. Reduced post-transplant healthcare utilization inpatient care indicates that transplantation may provide a sustained decrease in healthcare costs over time.

    Novel peptides that inhibit heparanase activation of the coagulation system2014In: Thrombosis and Haemostasis, ISSN 0340-6245, Vol. 112, no 3, p. 466-477Article in journal (Refereed)
    Abstract [en]

    Heparanase is implicated in cell invasion, tumour metastasis and angiogenesis. It forms a complex and enhances the activity of the blood coagulation initiator tissue factor (IF). We describe new peptides derived from the solvent accessible surface of TF pathway inhibitor 2 (TFPI-2) that inhibit the heparanase procoagulant activity. Peptides were evaluated in vitro by measuring activated coagulation factor X levels and co-immunoprecipitation. Heparanase protein and/or lipopolysaccharide (LPS) were injected intra-peritoneally and inhibitory peptides were injected subcutaneously in mouse models. Plasma was analysed by ELISA for thrombin-antithrombin complex (TAT), D-dimer as markers of coagulation activation, and interleukin 6 as marker of sepsis severity. Peptides 5, 6, 7, 21 and 22, at the length of 11-14 amino acids, inhibited heparanase procoagulant activity but did not affect IF activity. Injection of newly identified peptides 5, 6 and 7 significantly decreased or abolished TAT plasma levels when heparanase or LPS were pre-injected, and inhibited clot formation in an inferior vena cava thrombosis model. To conclude, the solvent accessible surface of TFPI-2 first Kunitz domain is involved in TF/heparanase complex inhibition. The newly identified peptides potentially attenuate activation of the coagulation system induced by heparanase or LPS without predisposing to significant bleeding tendency.

    Successful repeated treatment with high dose cyclophosphamide and autologous blood stem cell transplantation in CIDP2009In: BMJ case reports, ISSN 1757-790XArticle in journal (Refereed)
    Abstract [en]

    Chronic inflammatory demyelinating polyneuropathy (CIDP) is characterised by the occurrence of symmetrical weakness and sensory impairment in arms and legs. The course is relapsing or chronic and progressing. CIDP is considered to be an autoimmune disease, which is supported by the beneficial response to immunomodulating therapies in most patients. We report on a patient with CIDP who has been in remission for more than 3 years after treatment with high dose cyclophosphamide and autologous blood stem cell transplantation in CIDP on two occasions.

    Second Allogeneic Hematopoietic Cell Transplantation for Patients with Fanconi Anemia and Bone Marrow Failure2015In: Biology of blood and marrow transplantation, ISSN 1083-8791, E-ISSN 1523-6536, Vol. 21, no 10, p. 1790-1795Article in journal (Refereed)
    Abstract [en]

    A second allogeneic hematopoietic cell transplantation (HCT) is the sole salvage option for individuals who develop graft failure after their first HCT. Data on outcomes after second HCT in patients with Fanconi anemia (FA) are scarce. Here we report outcomes after second allogeneic HCT for FA (n = 81). The indication for second HCT was graft failure after the first HCT. Transplantations were performed between 1990 and 2012. The timing of the second HCT predicted subsequent graft failure and survival. Graft failure was high when the second HCT was performed less than 3 months from the first. The 3-month probability of graft failure was 69% when the interval between the first HCT and second HCT was less than 3 months, compared with 23% when the interval was longer (P < .001). Consequently, the 1-year survival rate was substantially lower when the interval between the first and second HCTs was less than 3 months compared with longer (23% vs 58%; P = .001). The corresponding 5-year probability of survival was 16% and 45%, respectively (P = .006). Taken together, these data suggest that fewer than one-half of patients with FA undergoing a second HCT for graft failure are long-term survivors. There is an urgent need to develop strategies to reduce the rate of graft failure after first HCT.

    Not all IGHV3-21 chronic lymphocytic leukemias are equal: prognostic considerations2015In: Blood, ISSN 0006-4971, E-ISSN 1528-0020, Vol. 125, no 5, p. 856-859Article in journal (Refereed)
    Abstract [en]

    An unresolved issue in chronic lymphocytic leukemia (CLL) is whether IGHV3-21 gene usage, in general, or the expression of stereotyped B-cell receptor immunoglobulin defining subset # 2 (IGHV3-21/IGLV3-21), in particular, determines outcome for IGHV3-21-utilizing cases. We reappraised this issue in 8593 CLL patients of whom 437 (5%) used the IGHV3-21 gene with 254/437 (58%) classified as subset # 2. Within subset # 2, immunoglobulin heavy variable (IGHV)-mutated cases predominated, whereas non-subset # 2/IGHV3-21 was enriched for IGHV-unmutated cases (P =.002). Subset # 2 exhibited significantly shorter time-to-first-treatment (TTFT) compared with non-subset # 2/IGHV3-21 (22 vs 60 months, P =.001). No such difference was observed between non-subset # 2/IGHV3-21 vs the remaining CLL with similar IGHV mutational status. In conclusion, IGHV3-21 CLL should not be axiomatically considered a homogeneous entity with adverse prognosis, given that only subset # 2 emerges as uniformly aggressive, contrasting non-subset # 2/IGVH3-21 patients whose prognosis depends on IGHV mutational status as the remaining CLL.

    Recurrent mutations refine prognosis in chronic lymphocytic leukemia2015In: Leukemia, ISSN 0887-6924, E-ISSN 1476-5551, Vol. 29, p. 329-336Article in journal (Refereed)
    Abstract [en]

    Through the European Research Initiative on chronic lymphocytic leukemia (CLL) (ERIC), we screened 3490 patients with CLL for mutations within the NOTCH1 (n=3334), SF3B1 (n=2322), TP53 (n=2309), MYD88 (n=1080) and BIRC3 (n=919) genes, mainly at diagnosis (75%) and before treatment (>90%). BIRC3 mutations (2.5%) were associated with unmutated IGHV genes (U-CLL), del(11q) and trisomy 12, whereas MYD88 mutations (2.2%) were exclusively found among M-CLL. NOTCH1, SF3B1 and TP53 exhibited variable frequencies and were mostly enriched within clinically aggressive cases. Interestingly, as the timespan between diagnosis and mutational screening increased, so too did the incidence of SF3B1 mutations; no such increase was observed for NOTCH1 mutations. Regarding the clinical impact, NOTCH1 mutations, SF3B1 mutations and TP53 aberrations (deletion/mutation, TP53ab) correlated with shorter time-to-first-treatment (P<0.0001) in 889 treatment-naive Binet stage A cases. In multivariate analysis (n=774), SF3B1 mutations and TP53ab along with del(11q) and U-CLL, but not NOTCH1 mutations, retained independent significance. Importantly, TP53ab and SF3B1 mutations had an adverse impact even in U-CLL. In conclusion, we support the clinical relevance of novel recurrent mutations in CLL, highlighting the adverse impact of SF3B1 and TP53 mutations, even independent of IGHV mutational status, thus underscoring the need for urgent standardization/harmonization of the detection methods.

    Chromosomal translocations and karyotype complexity in chronic lymphocytic leukemia: A systematic reappraisal of classic cytogenetic data2014In: American Journal of Hematology, ISSN 0361-8609, E-ISSN 1096-8652, Vol. 89, no 3, p. 249-255Article in journal (Refereed)
    Abstract [en]

    The significance of chromosomal translocations (CTRAs) and karyotype complexity (KC) in chronic lymphocytic leukemia (CLL) remains uncertain. To gain insight into these issues, we evaluated a series of 1001 CLL cases with reliable classic cytogenetic data obtained within 6 months from diagnosis before any treatment. Overall, 320 cases were found to carry 1 CTRAs. The most frequent chromosome breakpoints were 13q, followed by 14q, 18q, 17q, and 17p; notably, CTRAs involving chromosome 13q showed a wide spectrum of translocation partners. KC (3 aberrations) was detected in 157 cases and significantly (P<0.005) associated with unmutated IGHV genes and aberrations of chromosome 17p. Furthermore, it was identified as an independent prognostic factor for shorter time-to-first-treatment. CTRAs were assigned to two categories (i) CTRAs present in the context of KC, often with involvement of chromosome 17p aberrations, occurring mostly in CLL with unmutated IGHV genes; in such cases, we found that KC rather than the presence of CTRAs per se negatively impacts on survival; (ii) CTRAs in cases without KC, having limited if any impact on survival. On this evidence, we propose that all CTRAs in CLL are not equivalent but rather develop by different processes and are associated with distinct clonal behavior. Am. J. Hematol. 89:249-255, 2014.

    Abstract [en]

    Key Clinical Message Inherited conditions associated with thrombocytopenia should be included in the differential diagnosis of young patients with refractory immune thrombocytopenia (ITP), even in the absence of a positive family history. Early identification of such conditions is of vital importance in order to reach the right diagnosis and avoid unnecessary or even harmful medication.

    Splenic marginal-zone lymphoma: ontogeny and genetics2015In: Leukemia and Lymphoma, ISSN 1042-8194, E-ISSN 1029-2403, Vol. 56, no 2, p. 301-310Article, review/survey (Refereed)
    Abstract [en]

    Splenic marginal-zone lymphoma (SMZL) is a rare tumor that has recently emerged as a prototype for how the interplay between genetics and environment shapes the natural history of lymphomas. Indeed, the recent identification of molecular immunogenetic subgroups within SMZL may prove to be relevant not only for the sub-classification of the disease but also for improved understanding of the underlying biology. In contrast to other B-cell lymphomas, SMZL lacks a characteristic genetic lesion, although the majority of cases harbor genomic aberrations, as recently revealed by high-throughput studies that identified recurrent genetic aberrations, several in pathways related to marginal-zone differentiation and B-cell signaling. Here we provide an overview of recent research into the molecular and cellular biology of SMZL and related disorders, with special emphasis on immunogenetics and genomic aberrations, and discuss the value of molecular and cellular markers for the diagnosis and differential diagnosis of these entities.

    Philadelphia chromosome-negative classical myeloproliferative neoplasms: revised management recommendations from European LeukemiaNet2018In: Leukemia, ISSN 0887-6924, E-ISSN 1476-5551, Vol. 32, no 5, p. 1057-1069Article, review/survey (Refereed)
    Abstract [en]

    This document updates the recommendations on the management of Philadelphia chromosome-negative myeloproliferative neoplasms (Ph-neg MPNs) published in 2011 by the European LeukemiaNet (ELN) consortium. Recommendations were produced by multiple-step formalized procedures of group discussion. A critical appraisal of evidence by using Grades of Recommendation, Assessment, Development and Evaluation (GRADE) methodology was performed in the areas where at least one randomized clinical trial was published. Seven randomized controlled trials provided the evidence base; earlier phase trials also informed recommendation development. Key differences from the 2011 diagnostic recommendations included: lower threshold values for hemoglobin and hematocrit and bone marrow examination for diagnosis of polycythemia vera (PV), according to the revised WHO criteria; the search for complementary clonal markers, such as ASXL1, EZH2, IDH1/IDH2, and SRSF2 for the diagnosis of myelofibrosis (MF) in patients who test negative for JAK2V617, CALR or MPL driver mutations. Regarding key differences of therapy recommendations, both recombinant interferon alpha and the JAK1/JAK2 inhibitor ruxolitinib are recommended as second-line therapies for PV patients who are intolerant or have inadequate response to hydroxyurea. Ruxolitinib is recommended as first-line approach for MF-associated splenomegaly in patients with intermediate-2 or high-risk disease; in case of intermediate-1 disease, ruxolitinib is recommended in highly symptomatic splenomegaly. Allogeneic stem cell transplantation is recommended for transplant-eligible MF patients with high or intermediate-2 risk score. Allogeneic stem cell transplantation is also recommended for transplant-eligible MF patients with intermediate-1 risk score who present with either refractory, transfusion-dependent anemia, blasts in peripheral blood > 2%, adverse cytogenetics, or high-risk mutations. In these situations, the transplant procedure should be performed in a controlled setting.

    Clinical end points for drug treatment trials in BCR-ABL1-negative classic myeloproliferative neoplasms: consensus statements from European LeukemiaNET (ELN) and Internation Working Group-Myeloproliferative Neoplasms Research and Treatment (IWG-MRT)2015In: Leukemia, ISSN 0887-6924, E-ISSN 1476-5551, Vol. 29, no 1, p. 20-26Article in journal (Refereed)
    Abstract [en]

    The discovery of somatic mutations, primarily JAK2V617F and CALR, in classic BCR-ABL1-negative myeloproliferative neoplasms (MPNs) has generated interest in the development of molecularly targeted therapies, whose accurate assessment requires a standardized framework. A working group, comprised of members from European LeukemiaNet (ELN) and International Working Group for MPN Research and Treatment (IWG-MRT), prepared consensus-based recommendations regarding trial design, patient selection and definition of relevant end points. Accordingly, a response able to capture the long-term effect of the drug should be selected as the end point of phase II trials aimed at developing new drugs for MPNs. A time-to-event, such as overall survival, or progression-free survival or both, as co-primary end points, should measure efficacy in phase III studies. New drugs should be tested for preventing disease progression in myelofibrosis patients with early disease in randomized studies, and a time to event, such as progression-free or event-free survival should be the primary end point. Phase III trials aimed at preventing vascular events in polycythemia vera and essential thrombocythemia should be based on a selection of the target population based on new prognostic factors, including JAK2 mutation. In conclusion, we recommended a format for clinical trials in MPNs that facilitates communication between academic investigators, regulatory agencies and drug companies.

    Safety and Side Effects of Using Placenta-Derived Decidual Stromal Cells for Graft-versus-Host Disease and Hemorrhagic Cystitis2017In: Frontiers in Immunology, ISSN 1664-3224, E-ISSN 1664-3224, Vol. 8, article id 795Article in journal (Refereed)
    Abstract [en]

    Mesenchymal stromal cells (MSCs) are increasingly used in regenerate medicine. Placenta-derived decidual stromal cells (DSCs) are a novel therapy for acute graft-versus-host-disease (GVHD) and hemorrhagic cystitis (HC) after allogeneic hematopoietic stem cell transplantation (HSCT). DSCs are more immunosuppressive than MSCs. We assessed adverse events and safety using DSCs among 44 treated patients and 40 controls. The median dose of infused cells was 1.5 (range 0.9–2.9) × 106 DSCs/kg. The patients were given 2 (1–5) doses, with a total of 82 infusions. Monitoring ended 3 months after the last DSC infusion. Three patients had transient reactions during DSC infusion. Laboratory values, hemorrhages, and transfusions were similar in the two groups. The frequency of leukemic relapse (2/2, DSC/controls) and invasive fungal infections (6/6) were the same in the two groups. Causes of death were those seen in HSCT patients: infections (5/3), respiratory failure (1/1), circulatory failure (3/1), thromboembolism (1/0), multiorgan failure (0/1), and GVHD and others (2/7). One-year survival for the DSC patients with GVHD was 67%, which was significantly better than achieved previously at our center. One-year survival was 90% in the DSC-treated HC group. DSC infusions appear safe. Randomized studies are required to prove efficacy.

    Pretransplant Consolidation Is Not Beneficial for Adults with ALL Undergoing Myeloablative Allogeneic Transplantation2018In: Biology of blood and marrow transplantation, ISSN 1083-8791, E-ISSN 1523-6536, Vol. 24, no 5, p. 945-955Article in journal (Refereed)
    Abstract [en]

    Allogeneic hematopoietic cell transplantation (alloHCT) is curative for patients with acute lymphoblastic leukemia (ALL) who achieve complete remission (CR1) with chemotherapy. However, the benefit of consolidation chemotherapy remains uncertain in patients undergoing alloHCT. We compared clinical outcomes of 524 adult patients with ALL in CR1 who received ≥2 (n = 109), 1 (n = 93), or 0 cycles (n = 322) of consolidation before myeloablative alloHCT from 2008 to 2012. As expected, time to alloHCT was longer with increasing cycles of consolidation. Patients receiving ≥2, 1, or 0 cycles of consolidation had an adjusted 3-year cumulative incidence of relapse of 20%, 27%, and 22%; 1-year transplant-related mortality (TRM) of 16%, 18%, and 23%; adjusted 3-year leukemia-free survival (LFS) of 54%, 48%, and 47%; and 3-year overall survival (OS) of 63%, 59%, and 54% (all P values >.40). Multivariable analysis confirmed that consolidation was not prognostic for LFS (relative risk, 1.20, 95% confidence interval, .86 to 1.67; P = .28 for no consolidation; RR, 1.18, 95% confidence interval, .79 to 1.76; P = .41 for 1 cycle versus ≥2 cycles = reference). Similarly, consolidation was not associated with OS, relapse, TRM, or graft-versus-host disease. We conclude that consolidation chemotherapy does not appear to provide added benefit in adult ALL patients with available donors who undergo myeloablative alloHCT in CR1.

    MDM2 promotor polymorphism and disease characteristics in chronic lymphocytic leukemia: results of an individual patient data-based meta-analysis2014In: Haematologica (online), ISSN 0390-6078, E-ISSN 1592-8721, Vol. 99, no 8, p. 1285-1291Article in journal (Refereed)
    Abstract [en]

    A number of single nucleotide polymorphisms have been associated with disease predisposition in chronic lymphocytic leukemia. A single nucleotide polymorphism in the MDM2 promotor region, MDM2SNP309, was shown to soothe the p53 pathway. In the current study, we aimed to clarify the effect of the MDM2SNP309 on chronic lymphocytic leukemia characteristics and outcome. We performed a meta-analysis of data from 2598 individual patients from 10 different cohorts. Patients' data and genetic analysis for MDM2SNP309 genotype, immunoglobulin heavy chain variable region mutation status and fluorescence in situ hybridization results were collected. There were no differences in overall survival based on the polymorphism (log rank test, stratified by study cohort; P=0.76; GG genotype: cohort-adjusted median overall survival of 151 months; TG: 153 months; TT: 149 months). In a multivariable Cox proportional hazards regression analysis, advanced age, male sex and unmutated immunoglobulin heavy chain variable region genes were associated with inferior survival, but not the MDM2 genotype. The MDM2SNP309 is unlikely to influence disease characteristics and prognosis in chronic lymphocytic leukemia. Studies investigating the impact of individual single nucleotide polymorphisms on prognosis are often controversial. This may be due to selection bias and small sample size. A meta-analysis based on individual patient data provides a reasonable strategy for prognostic factor analyses in the case of small individual studies. Individual patient data-based meta-analysis can, therefore, be a powerful tool to assess genetic risk factors in the absence of large studies.

    The HemoScreen, a novel haematology analyser for the point of care2016In: Journal of Clinical Pathology, ISSN 0021-9746, E-ISSN 1472-4146, Vol. 69, no 8, p. 720-725Article in journal (Refereed)
    Abstract [en]

    BACKGROUND AND AIMS: A haematology analyser, based on a new technology, is presented herein. The analyser that provides a complete blood count (CBC) and five-part differential accepts disposable cartridges containing all required reagents, making it maintenance-free and ideal for point-of-care (POC) settings. The test reproducibility and imperviousness to analytical errors are attributed to the imaging-based analysis employed. Imaging enables cell-morphology-based differentiation, which is analogous to the gold standard microscopic analysis. This article presents the HemoScreen new technology and evaluates its performance through a small-scale study conducted in its designated clinical settings.

    METHODS: Thirty anticoagulated whole blood samples were analysed on the HemoScreen and Sysmex XE-2100. Linear regression was performed for the methods comparison. Two samples with 15 replicates were processed for imprecision. Ease of use of the device was also considered.

    RESULTS: The HemoScreen demonstrated acceptable imprecision and good agreement with the Sysmex XE-2100. The white blood cells (WBCs), red blood cells (RBCs), haemoglobin (HGB), haematocrit (HCT), platelets (PLT), neutrophils, lymphocytes and eosinophils have coefficients of correlation (r) >0.97. For mean cell volume (MCV), mean cell HGB (MCH) and RBC distribution width (RDW), r values ranged from 0.92 to 0.96. For mean cell HGB concentration (MCHC) and monocytes r=0.82 was demonstrated. User-friendliness and suitability of the device for operation in the designated POC settings was also confirmed.

    CONCLUSIONS: The HemoScreen employs innovative technologies of viscoelastic focusing and microfluidics within a disposable cartridge for an image-based blood cell analysis. By providing accurate and repeatable CBC and five-part differential results within minutes and maintaining the simplicity of operation, the HemoScreen could have far-reaching implications for use at POC. Further extended evaluation is in progress.

    The nanoparticulate Quillaja saponin KGI exerts anti-proliferative eff ects by down-regulation of cell cycle molecules in U937 and HL-60 human leukemia cells2014In: Leukemia and Lymphoma, ISSN 1042-8194, E-ISSN 1029-2403, Vol. 55, no 7, p. 1618-1624Article in journal (Refereed)
    Abstract [en]

    Cancer cells are characterized by uncontrolled replication involving loss of control of cyclin dependent kinases (CDKs) and cyclins, and by abolished differentiation. In this study we introduce KGI, which is a nanoparticle with a Quillaja saponin as an active molecule. By the use of RNA array analysis and confirmation at the protein level, we show that KGI affects myeloid leukemia cells (in particular, the U937 monoblast cancer cell) by the following mechanisms: (A) ceasing cell replication via proteasome degradation, (B) down-regulation of key molecules at check points between G1/S and G2/M phases, (C) reduction of thymidine kinase activity, followed by (D) exit to differentiation and production of interleukin-8 (IL-8), eventually leading to apoptosis. Leukemia cell lines (U937 and HL-60 cells) were exposed to KGI for 8 h, after which the drug was removed. The cancer cells did not revert to replication over the following 10 days. Thus our findings suggest that the nanoparticle KGI inhibits proliferation and promotes differentiation in leukemic cells by interfering with the cell cycle process.

    Prognostic scoring systems for myelodysplastic syndromes (MDS) in a population-based setting: a report from the Swedish MDS register2018In: British Journal of Haematology, ISSN 0007-1048, E-ISSN 1365-2141, Vol. 181, no 5, p. 614-627Article in journal (Refereed)
    Abstract [en]

    The myelodysplastic syndromes (MDS) have highly variable outcomes and prognostic scoring systems are important tools for risk assessment and to guide therapeutic decisions. However, few population-based studies have compared the value of the different scoring systems. With data from the nationwide Swedish population-based MDS register we validated the International Prognostic Scoring System (IPSS), revised IPSS (IPSS-R) and the World Health Organization (WHO) Classification-based Prognostic Scoring System (WPSS). We also present population-based data on incidence, clinical characteristics including detailed cytogenetics and outcome from the register. The study encompassed 1329 patients reported to the register between 2009 and 2013, 14% of these had therapy-related MDS (t-MDS). Based on the MDS register, the yearly crude incidence of MDS in Sweden was 2<bold></bold>9 per 100000 inhabitants. IPSS-R had a significantly better prognostic power than IPSS (P<0<bold></bold>001). There was a trend for better prognostic power of IPSS-R compared to WPSS (P=0<bold></bold>05) and for WPSS compared to IPSS (P=0<bold></bold>07). IPSS-R was superior to both IPSS and WPSS for patients aged 70years. Patients with t-MDS had a worse outcome compared to de novo MDS (d-MDS), however, the validity of the prognostic scoring systems was comparable for d-MDS and t-MDS. In conclusion, population-based studies are important to validate prognostic scores in a real-world' setting. In our nationwide cohort, the IPSS-R showed the best predictive power.

    Silenced B-cell receptor response to autoantigen in a poor-prognostic subset of chronic lymphocytic leukemia2014In: Haematologica (online), ISSN 0390-6078, E-ISSN 1592-8721, Vol. 99, no 11, p. 1722-1730Article in journal (Refereed)
    Abstract [en]

    Chronic lymphocytic leukemia B cells express auto/xeno antigen-reactive antibodies that bind to self-epitopes and resemble natural IgM antibodies in their repertoire. One of the antigenic structures recognized is oxidation-induced malonedialdehyde that is present on low-density lipoprotein, apoptotic blebs, and on certain microbes. The poor-prognostic stereotyped subset #1 (Clan I IGHV genes-IGKV1(D)-39) express IgM B-cell receptors that bind oxidized low-density lipoprotein. In this study, we have used for the first time this authentic cognate antigen for analysis of downstream B-cell receptor-signal transduction events, since it is more faithful to B-cell physiology than anti-IgM. Multivalent oxidized low-density lipoprotein showed specific binding to subset #1 IgM/IgD B-cell receptors, whereas native low-density lipoprotein did not. The antigen binding induced prompt receptor clustering followed by internalization. However, the receptor-signal transduction was silenced, revealing no Ca2+ mobilization or cell-cycle entry, while phosphorylated extracellular-regulated kinase 1/2 basal levels were high and could not be elevated further by oxidized low-density lipoprotein. Interestingly, B-cell receptor responsiveness was recovered after 48-h culture in the absence of antigen in half of the cases. Toll-like receptor 9-ligand was found to breach the B-cell receptor-signaling incompetence in 5 of 12 cases pointing to intra-subset heterogeneity. Altogether, this study supports B-cell receptor unresponsiveness to cognate self-antigen on its own in poor-prognostic subset #1 chronic lymphocytic leukemia, indicating that these cells proliferate by other mechanisms that may override B-cell receptor silencing brought about in a context of self-tolerance/anergy. These novel findings have implications for the understanding of chronic lymphocytic leukemia pathobiology and therapy.
