Abstract
Acquired thrombotic thrombocytopenic purpura (aTTP) is a medical emergency requiring urgent plasma exchange and immunosuppressive agents. Recently, the therapeutic options have been expanded by the approval of a novel anti-von Willebrand factor (vWF) nanobody, caplacizumab, inhibiting vWF-platelet aggregation. Here, we present a rare case of a patient affected by immune-mediated TTP (iTTP) reporting ischemic stroke caused by a real iTTP exacerbation during caplacizumab administration and subsequent pancytopenia caused by cytomegalovirus (CMV) infection that mimicked another iTTP exacerbation. The case is a real-life example of a not-frequent iTTP exacerbation in the caplacizumab era and of the new management issues arising with the introduction of the new drugs in clinical practice, highlighting the need of new comprehensive response criteria and treatment guidelines.

Fatigue in newly diagnosed acute myeloid leukaemia: general population comparison and predictive factors. BMJ Support Palliat Care 2023; 13:e344-e351. [PMID: 33941573 PMCID: PMC8563490 DOI: 10.1136/bmjspcare-2020-002312] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/18/2020] [Revised: 03/30/2021] [Accepted: 04/02/2021] [Indexed: 01/03/2023]
Abstract
OBJECTIVES This study compared the burden of fatigue between treatment-naïve patients with newly diagnosed acute myeloid leukaemia (AML) and the general population and investigated patient factors associated with fatigue severity. METHODS Pretreatment patient-reported fatigue was assessed with the Functional Assessment of Chronic Illness Therapy-Fatigue questionnaire in a sample of 463 newly diagnosed patients with AML who were enrolled in a clinical trial. Multivariable linear regression models were used to estimate the adjusted mean differences in fatigue between patients with AML and adults from the general population (n=847) by AML disease risk categories. A clinically meaningful difference in fatigue was defined as ≥3 points. Univariable and multivariable linear regression models were used to identify sociodemographic, clinical and molecular correlates of worse fatigue in patients with AML. RESULTS Patients with AML reported adjusted mean fatigue scores that were 7.5 points worse than the general population (95% CI -8.6 to -6.4, p<0.001). Across AML disease risk categories, adjusted mean differences in fatigue compared with the general population ranged from 6.7 points worse (patients with favourable risk: 95% CI -8.6 to -4.8, p<0.001) to 8.9 points worse (patients with poor risk, 95% CI -10.5 to -7.2, p<0.001). Overall, 91% of patients with AML reported fatigue that was equal to or worse than the general population's median fatigue score. Higher pretreatment fatigue was independently associated with female sex, WHO performance status ≥1 and lower platelet levels. CONCLUSIONS Patients with newly diagnosed AML reported worse fatigue than the general population, and mean differences exceeded twice the threshold for clinical significance. Our findings may help to identify patients with AML most likely to benefit from supportive care interventions to reduce fatigue.

Impact of gemtuzumab ozogamicin consolidation on hematopoietic stem cells (HSCs) mobilization in AML: analysis of 20 patients. Ann Hematol 2023; 102:769-775. [PMID: 36795117 DOI: 10.1007/s00277-023-05129-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2022] [Accepted: 02/05/2023] [Indexed: 02/17/2023]
Abstract
Gemtuzumab ozogamicin (GO), is an anti-CD33 monoclonal antibody, approved for AML CD33 + , those patients with low and intermediate-risk who obtain a complete response may also be candidated for consolidation with autologous stem cell transplantation (ASCT). However, there are scant data on the mobilization of hemopoietic stem cells (HSC) after fractionated GO. We retrospectively studied data from five Italian centers and identified 20 patients (median age 54 years, range 29-69, 15 female, 15 NPM1mutated) that attempted HSC mobilization after fractionated doses of GO + "7 + 3" regimen and 1-2 cycles of consolidation (GO + HDAC + daunorubicin). After chemotherapy and standard G-CSF, 11/20 patients (55%) reached the threshold of 20 CD34 + /µL, and HSC were successfully harvested, while 9 patients (45%) failed. The median day of apheresis was Day + 26 from the start of chemotherapy (range 22-39 days). In good mobilizer patients, the median circulating CD34 + cells were 35.9 cells/µL and the median CD34 + harvested were 4.65 × 106/kg of patients' body weight. With a median follow-up of 12.7 months, at 24 months from the first diagnosis, 93.3% of all 20 patients were alive and the median overall survival was 25 months. The 2-year RFS rate from the timepoint of the first CR was 72.6%, while the median RFS was not reached. However, only five patients underwent ASCT and achieved full engraftment.In conclusion, in our cohort of patients, the addition of GO reduced HSC mobilization and harvesting, which was reached in about 55% of patients. Nevertheless, further studies are warranted to evaluate the effects of fractionated doses of GO on HSC mobilization and ASCT outcomes.

[PMID: 36747900 PMCID: PMC9899007 DOI: 10.2147/idr.s393802] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/18/2022] [Accepted: 12/23/2022] [Indexed: 02/01/2023] Open
Abstract
Purpose To evaluate the benefits and safety of the empiric antibiotic treatment (EAT) active against KPC-K. pneumoniae in febrile neutropenic patients with acute leukaemia (AL) who are colonised by KPC-K. pneumoniae. Patients and Methods A 7-year (2013-2019) retrospective observational cohort study was conducted at the Haematology, Sapienza Rome University (Italy) on 94 febrile neutropenia episodes (FNE) in AL patients KPC-K. pneumoniae carriers treated with active EAT. Results Eighty-two (87%) FNE were empirically treated with antibiotic combinations [38 colistin-based and 44 ceftazidime-avibactam (CAZAVI)-based], 12 with CAZAVI monotherapy. Successful outcomes were observed in 88/94 (94%) FNE, 46/49 (94%) microbiologically documented infections, and 24/27 (89%) gram-negative bloodstream infections (GNB-BSI). Mortality due to infective causes was 4.2% (2.1% within 1 week). KPC-K. pneumoniae infections caused 28/94 FNE (30%) and KPC-K. pneumoniae-BSI was documented in 22 FNE (23.4%) (85% of GNB-BSI), in all cases patients received active EAT, and 21 survived. KPC-K.pneumoniae-BSI mortality rate was 4.5%. CAZAVI-based EAT showed better results than colistin-based EAT (55/56 vs 33/38, p = 0.037), overall and without EAT modification (41/56 vs 20/38, p = 0.02). Empirical combinations including CAZAVI were successful in 98% of cases (43/44 vs 33/38 for colistin-based EAT, p = 0.01), without modifications in 82% (36/44 vs 20/28, p = 0.02). All deaths occurred in patients treated with colistin-based EAT (4/38 vs 0/56, p = 0.02). CAZAVI-containing EAT was the only independent factor for an overall successful response (HR 0.058, CI 0.013-1.072, p = 0.058). Nephrotoxicity occurred in 3(8%) patients undergoing colistin-based EAT (none in those undergoing CAZAVI-based EAT, p = 0.02). Conclusion KPC-K. pneumoniae infections are frequent in colonised AL patients with FNE. EAT with active antibiotics, mainly CAZAVI-based combinations, was effective, safe, and associated with low overall and KPC-K. pneumoniae-BSI-related mortality.

Immunogenicity of SARS-CoV-2 vaccination in patients undergoing autologous stem cell transplantation. A multicentric experience. Front Oncol 2022; 12:897937.

Abstract
COVID-19 disease has a strong impact on hematological patients; those receiving autologous hematopoietic stem cell transplantation (aHSCT) represent a particularly vulnerable group, in which the effectiveness of vaccination is very variable. Chiarucci et al. showed that patients affected by non-Hodgkin lymphoma (NHL) and treated with rituximab experienced a lower rate of immunization against SARS-CoV-2 (54%), as well as significantly lower IgG antibody titers. In our multicenter retrospective observational study, we included 82 patients who underwent aHSCT, divided into two groups: 58 patients vaccinated after aHSCT (group A) and 24 vaccinated before getting transplantation (group B). In group A, 39 (67%) patients had positive serology, and the rate of positivity increased with time after aHSCT. In the subgroup of patients with NHL, the administration of rituximab predicted negative serology, particularly when administered in the 6 months before vaccination (13% response rate). Patients affected by plasma cells had a higher rate of positivity (83% overall), independently of the time to aHSCT. In group B, no patient who initially showed positive serology became negative after transplantation, so the aHSCT did not affect the response to the vaccination. Our study confirmed the role of rituximab as a negative predictor of response to SARS-CoV-2 vaccination, whereas the conditioning and transplantation procedure itself seemed to be less important.

Autologous stem cell transplantation (ASCT) for acute myeloid leukemia in patients in first complete remission after one versus two induction courses: A study from the ALWP of the EBMT. Cancer Med 2022; 12:1482-1491. [PMID: 35891608 PMCID: PMC9883552 DOI: 10.1002/cam4.5039] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2022] [Revised: 06/19/2022] [Accepted: 07/07/2022] [Indexed: 02/02/2023] Open
Abstract
BACKGROUND Achieving complete remission (CR) is the main goal in AML treatment and a prerequisite for successful autologous stem cell transplantation (ACT). METHODS Comparing results of peripheral blood ACT in patients with AML in CR1 attained following 1 versus 2 chemotherapy courses transplanted in 2000-2019. RESULTS Patients 1532 (84%) with one and 293 (16%) patients with two induction chemotherapies courses (a total of 1825 patients) were included in the study. Follow-up was 7.9 (95% CI: 7.4-8.4) and 7.7 (95% CI: 7.0-8.6) years (p = 0.8). Time from diagnosis to ACT was 4.7 (range, 3.9-5.8) versus 5.7 (range, 4.7-7.1) months (p < 0.001), respectively. Leukemia free survival (LFS) and overall survival (OS) at 5 years were inferior for patients achieving CR1 with 2 versus 1 course of chemotherapy: 26.6% versus 41.7% (HR = 1.42 [95% CI: 1.22-1.66], p < 0.001) and 36.2% versus 53.3%, (HR = 1.48 [95% CI: 1.25-1.75], p < 0.001), and 5-year relapse incidence (RI) was higher: 67.2% versus 52.3%, (HR = 1.46 [95% CI: 1.25-1.72], p < 0.001). Five-year non-relapse mortality (NRM) was 6.2% versus 6.0% for patients with 2 versus 1 chemotherapy courses, and did not differ significantly (HR = 1.31 [95% CI: 0.81-2.10], p = 0.27). CONCLUSIONS LFS and OS were inferior and relapse rate was higher in AML patients who received two inductions chemotherapy courses to reach CR1 before being autografted. AML patients who required 2 induction courses to achieve remission, may be offered allogeneic transplantation rather than an autologous one in an attempt to reduce their high RI and improve outcomes.

Autologous stem cell transplantation in favorable-risk acute myeloid leukemia: single-center experience and current challenges. Int J Hematol 2022; 116:586-593.

Abstract
BACKGROUND Autologous stem cell transplantation (ASCT) has gained growing consideration as a treatment option for favorable-risk acute myeloid leukemia (FR-AML) in first complete remission (CR1), compared with chemotherapy. MATERIALS AND METHODS We report the long-term outcomes of 117 consecutive patients with FR-AML fit for intensive chemotherapy diagnosed in our center between 1999 and 2020, who underwent ASCT. RESULTS Sixty-five of the 117 were eligible for intensive post-remission treatment, and 42 of those 65 received ASCT. Median follow up was 132 months. Overall survival (OS) and disease-free survival (DFS) were 75% and 76%. Higher doses of CD34 + stem cell infusions negatively impacted DFS in multivariate analysis. Core-binding factor (CBF) leukemia was an independent prognostic factor for improved DFS. No differences based on pre-transplant measurable residual disease (MRD) were observed. In CBF leukemia, 10-year DFS is 72% for MRD-positive patients versus 100% for MRD negative patients. CONCLUSIONS ASCT is effective and safe in FR-AML patients. In CBF leukemia, ASCT provides excellent results regardless of achievement of bone marrow MRD negativity. In NPM1-mutated/FLT3-wild type (mNPM1) AML, early molecular response seems to have more impact on prognosis. Prospective investigation of the role of gemtuzumab ozogamicin in this setting is ongoing.

Reduced mortality from KPC-K.pneumoniae bloodstream infection in high-risk patients with hematological malignancies colonized by KPC-K.pneumoniae. BMC Infect Dis 2021; 21:1079. [PMID: 34666695 PMCID: PMC8524821 DOI: 10.1186/s12879-021-06747-8] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2020] [Accepted: 09/29/2021] [Indexed: 01/08/2023] Open
Abstract
BACKGROUND KPC-K.pneumoniae bloodstream infection (KPC-KpBSI) mortality rate in patients with hematological malignancies is reported about 60%. The initial treatment active against KPC-K.pneumoniae is crucial for survival and KPC-K.pneumoniae rectal colonization usually precedes KPC-KpBSI. We evaluated the impact on KPC-KpBSI mortality of the preemptive use of antibiotics active against KPC-K.pneumoniae, as opposed to inactive or standard empiric antibiotics, for the empiric treatment of febrile neutropenia episodes in patients with hematological malignancy identified as KPC-K.pneumoniae intestinal carriers. METHODS We compared the outcomes of KPC-KpBSIs occurring in high-risk hematological patients known to be colonized with KPC-K.pneumoniae, during two time periods: March2012-December2013 (Period 1, initial approach to KPC-K.pneumoniae spread) and January2017-October2018 (Period 2, full application of the preemptive strategy). The relative importance of the various prognostic factors that could influence death rates were assessed by forward stepwise logistic regression models. RESULTS KPC-KpBSI-related mortality in hematological patients identified as KPC-K.pneumoniae carriers dropped from 50% in Period 1 to 6% in Period 2 (p < 0.01), from 58 to 9% in acute myeloid leukemia carriers(p < 0.01). KPC-KpBSIs developed in patients identified as KPC-K.pneumoniae carriers were initially treated with active therapy in 56% and 100% of cases in Period 1 and Period 2, respectively (p < 0.01), in particular with an active antibiotic combination in 39 and 94% of cases, respectively(p < 0.01). The 61% of KPC-KpBSI observed in Period 1 developed during inactive systemic antibiotic treatment (none in Period 2, p < 0.01), fatal in the 73% of cases. Overall, KPC-KpBSI-related mortality was 88% with no initial active treatment, 11.5% with at least one initial active antibiotic (p < 0.01), 9% with initial active combination. Only the initial active treatment resulted independently associated with survival. CONCLUSIONS In high-risk hematological patients colonized by KPC-K.pneumoniae, the empiric treatment of febrile neutropenia active against KPC-K.pneumoniae reduced KPC-KpBSI-related mortality to 6% and prevented fatal KPC-KpBSI occurrence during inactive systemic antibiotic treatment.

Abstract
Myeloid sarcoma (MS) is a very rare disease in both adults and children. Prognosis is poor in adults; in the pediatric age, the prognostic impact of extramedullary disease is controversial. Systemic therapy represents the mainstay of treatment even in isolated MS, but a comparison between different induction regimens is very limited in the literature. To date, it is still not clear if induction treatment should differ from that of other acute myeloid leukemias and stem cell transplant is considered for consolidation in both leukemic patients and in those with isolated disease. Our study describes a retrospective series of 13 cases of MS (adults and children), diagnosed and treated at our institute over 18 years. We report the results of immunophenotypic, cytogenetic and molecular studies, therapeutic approaches, and outcome, in order to establish the best strategy for patients' workup.

Abstract
Immune-mediated thrombotic thrombocytopenic purpura (iTTP) is a rare, life-threatening thrombotic microangiopathy caused by severe ADAMTS13 (a disintegrin and metalloproteinase with thrombospondin motifs 13) deficiency, recurring in 30–50% of patients. The common human leukocyte antigen (HLA) variant rs6903608 was found to be associated with prevalent iTTP, but whether this variant is associated with disease relapse is unknown. To estimate the impact of rs6903608 on iTTP onset and relapse, we performed a case-control and cohort study in 161 Italian patients with a first iTTP episode between 2002 and 2018, and in 456 Italian controls. Variation in rs6903608 was strongly associated with iTTP onset (homozygotes odds ratio (OR) 4.68 (95% confidence interval (CI) 2.67 to 8.23); heterozygotes OR 1.64 (95%CI 0.95 to 2.83)), which occurred over three years earlier for each extra risk allele (β −3.34, 95%CI −6.69 to 0.02). Of 153 survivors (median follow-up 4.9 years (95%CI 3.7 to 6.1)), 44 (29%) relapsed. The risk allele homozygotes had a 46% (95%CI 36 to 57%) absolute risk of relapse by year 6, which was significantly higher than both heterozygotes (22% (95%CI 16 to 29%)) and reference allele homozygotes (30% (95%CI 23 to 39%)). In conclusion, HLA variant rs6903608 is a risk factor for both iTTP onset and relapse. This newly identified biomarker may help with recognizing patients at high risk of relapse, who would benefit from close monitoring or intensified immunosuppressive therapy.

Abstract
INTRODUCTION Acute lymphoblastic leukemia is the most frequent hematologic malignancy in children. Almost 95% of children potentially achieve a complete remission after the induction treatment, but over the last years, new insights in the genomic disease profile and in minimal residual disease detection techniques have led to an improvement in the prognostic stratification, identifying selected patients' subgroups with peculiar therapeutic needs. AREAS COVERED According to a comprehensive search of peer-review literature performed in Pubmed, in this review we summarize the recent evidences on the induction treatment strategies comprised in the children acute lymphoblastic leukemia scenario, focusing on the role of key drugs such as corticosteroids and asparaginase and discussing the crucial significance of the genomic characterization at baseline which may drive the proper induction treatment choice. EXPERT OPINION Current induction strategies already produce durable remissions in a significant proportion of standard-risk children with acute lymphoblastic leukemia. A broader knowledge of the biologic features related to acute lymphoblastic leukemia subtypes with worse prognosis, and an optimization of targeted drugs now available, might lead to the achievement of long-term molecular remissions in this setting.

Abstract
BACKGROUND The prevalence of older patients with acquired thrombotic thrombocytopenic purpura (TTP) is increasing. There is scarce information on the prevalence of multimorbidity, polypharmacy and age-related diseases in aging TTP patients. This study aimed to evaluate the prevalence of multimorbidity and polypharmacy in a population of acquired TTP patients aged 65 years or more compared with a group of age-matched controls. METHODS Acquired TTP patients enrolled in the Milan TTP registry from December 1st 1999 to March 31th 2018 and aged 65 years or more at the date of last follow-up were evaluated. Controls were Italian healthy individuals recruited from 2006 to March 31th 2018 among friends and non-consanguineous relatives of patients tested for thrombophilia screening at the Angelo Bianchi Bonomi Hemophilia and Thrombosis Center of Milan. RESULTS 36 TTP patients and 127 age-matched controls were included. Compared with controls, TTP patients had a higher prevalence of multimorbidity and polypharmacy. They also showed a higher prevalence of autoimmune diseases, osteoporosis and arterial hypertension and were more chronically treated with corticosteroids and antiplatelets for primary cardiovascular prevention. All these results were confirmed after adjusting for sex. Compared with the general elderly population, TTP patients showed a higher prevalence of ischemic heart disease and stroke. CONCLUSIONS Our findings suggest that a careful comprehensive geriatric assessment of acquired TTP patients is necessary. It is important to look for other autoimmune diseases and such age-related comorbidities as osteoporosis, arterial hypertension, ischemic heart disease and cerebrovascular disease.

Abstract
AbstractThrombotic thrombocytopenic purpura (TTP) is a rare thrombotic microangiopathy (TMA) characterized by the severe deficiency of a disintegrin and metalloproteinase with a thrombospondin type 1 motif, member 13 (ADAMTS13) activity (< 10%). Rapid ADAMTS13 testing is crucial for an early diagnosis and optimal management of acute TTP. We evaluated the performance of the HemosIL AcuStar ADAMTS13 activity assay (Instrumentation Laboratory, Bedford, Massachusetts, United States), a fully automated chemiluminescent immunoassay with an analytical time of 33 minutes. A method comparison study was performed on 176 samples from 49 healthy donors and 127 TMA patients (109 TTP, 7 atypical hemolytic uremic syndrome, 11 other TMAs), comparing this new assay with an in-house FRETS-VWF73 assay and a commercial enzyme-linked immunosorbent assay (ELISA) (TECHNOZYM ADAMTS-13 Activity, Technoclone GmbH, Vienna, Austria). Agreement between methods was assessed with focus on ADAMTS13 activity less than 10%, the medical decision level relevant for TTP diagnosis. The HemosIL AcuStar ADAMTS13 Activity showed good correlation with both the FRETS-VWF73 (r = 0.96) and ELISA (r = 0.96) methods. Slope of the Passing–Bablok regression was 1.05 for FRETS-VWF73 and 1.02 for ELISA, and absolute bias at the medical decision level was +0.1 and +0.3%, respectively. The study also revealed high agreement with FRETS-VWF73 (kappa 0.97) and ELISA (kappa 0.98) methods in classifying TTP patients with a severe deficiency of ADAMTS13 activity. Because of its short turnaround time and full automation, the HemosIL AcuStar ADAMTS13 activity assay might become the assay of choice to rapidly test ADAMTS13 activity in plasma and thus establish the diagnosis of acute TTP in emergency settings.

Optimizing the pretransplant regimen for autologous stem cell transplantation in acute myelogenous leukemia: Better outcomes with busulfan and melphalan compared with busulfan and cyclophosphamide in high risk patients autografted in first complete remission: A study from the acute leukemia working party of the EBMT. Am J Hematol 2018; 93:859-866. [PMID: 29644709 DOI: 10.1002/ajh.25105] [Citation(s) in RCA: 22] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/05/2018] [Revised: 03/27/2018] [Accepted: 04/03/2018] [Indexed: 01/22/2023]
Abstract
Autologous stem cell transplantation remains a clinical option to consolidate some adult patients with acute myelogenous leukemia (AML) in first complete remission (CR1). In a small cohort of patients, we have previously shown better outcomes following Busulfan and Melphalan (BUMEL) over Busulfan and Cyclophosphamide (BUCY). To identify the subpopulations that might get the highest benefit with BUMEL, we designed a larger study. All adult patients with primary AML and available cytogenetics, autografted from January 2000 to December 2016 in CR1, were included: 1137 patients received BUCY and 512 BUMEL. All factors differing in distribution between the 2 conditioning groups were introduced in multivariate analyzes. In a primary analysis, we found an interaction between conditioning and the poor risk group defined as poor cytogenetics and/or presence of the FLT3-ITD mutation. During analysis of the poor risk group, 176 patients received BUCY and 62 BUMEL. BUMEL was associated with a lower RI at 5 years (53% versus 69%, HR: 0.52, P = .002), a better Leukaemia-free survival (LFS) (42% versus 25%, HR: 0.54, P = .002) and a better OS (54% versus 36%, HR: 0.61, P = .02). During analysis of the non poor risk group, 961 patients received BUCY and 450 BUMEL. At 5 years, the RI was 50% and 47%, the LFS 45% and 48% and the OS 56% and 60% respectively, with no significant difference. We conclude that BUMEL is the preferable conditioning regimen for the poor risk leukemic patients, while in AML patients without poor risk cytogenetics or FLT3 both conditioning regimens are valid.

Abstract
BACKGROUND Autologous stem cell transplantation (ASCT) for adult acute myelogenous leukemia (AML) is a valid therapeutic option for patients with good-risk and intermediate-risk disease. The authors used the registry of the European Society for Blood and Marrow Transplantation to compare combined busulfan and melphalan (BUMEL) with combined busulfan and cyclophosphamide (BUCY) before transplantation. METHODS From 2005 to 2013, 853 patients with available cytogenetics underwent ASCT in first remission, including 257 after receiving BUMEL and 596 after receiving BUCY. The proportion of patients with good-risk AML was lower in those who received BUMEL (14% vs 20%; P = .02). More patients who received BUMEL underwent autograft in molecular remission (89% vs 78%; P = .02). Three years after transplantation, the relapse incidence (RI) was 48.7%, the leukemia-free survival (LFS) rate was 47.7%, the overall survival (OS) rate was 66.2%, and the nonrelapse mortality (NRM) rate was 3.6%. RESULTS Patients who underwent an autograft after receiving BUMEL fared better than those who underwent an autograft after receiving BUCY with a lower RI (39.5% vs 52.2%; hazard ratio [HR], 0.65; 95% confidence interval [CI], 0.49-0.87; P = .003) a better LFS (55.4% vs 44.6%; HR, 0.69; 95% CI, 0.53-0.89; P = .005), and a better OS (73.8% vs 63%; HR, 0.62; 95% CI, 0.47-0.82; P = .0007). There was no difference in the NRM rate (BUMEL vs BUCY, 4.5% vs 3.2%, respectively). Among 74 patients in the BUMEL group and 187 in the BUCY group who underwent autograft in molecular remission, the RI was 30% versus 51%, respectively (univariate analysis; P = .01), and the LFS rate was 66% versus 47%, respectively (univariate analysis; P = .03). CONCLUSIONS In patients with AML in first complete remission who undergo ASCT, the BUMEL combination is a better preparative regimen. Cancer 2017;123:824-31. © 2016 American Cancer Society.

Abstract
Selective splenic artery embolization (SSAE) is a nonsurgical intervention characterized by the transcatheter occlusion of the splenic artery and/or its branch vessels using metallic coils or other embolic devices. It has been applied for the management of splenic trauma, hypersplenism with portal hypertension, hereditary spherocytosis, thalassemia and splenic hemangioma. We hereby describe a case of a patient affected by idiopathic thrombocytopenic purpura (ITP) and warm auto-immune hemolytic anemia (AIHA) both resistant to immunosuppressive and biological therapies, not eligible for a surgical intervention because of her critical conditions. She underwent SSAE and achieved a hematologic complete response within a few days without complications. SSAE is a minimally invasive procedure to date not considered a standard option in the management of AIHA and ITP. However, following the progressive improvement of the techniques, its indications have been extended, with a reduction in morbidity and mortality compared to splenectomy in patients with critical clinical conditions. SSAE was a lifesaving therapeutic approach for our patient and it may represent a real alternative for the treatment of resistant AIHA and ITP patients not eligible for splenectomy.

Abstract
BACKGROUND Thrombotic thrombocytopenic purpura (TTP) is a rare life-threatening disease. Of surviving patients, 45% develops an exacerbation or a late recurrence. Severe ADAMTS-13 deficiency, both during the acute episode and remission, is a well-established predictor of recurrence. The predictive value of anti-ADAMTS-13 antibodies, their inhibitory activity and Ig class subtype for disease recurrence is still to be established. OBJECTIVES To analyze ADAMTS-13-related biomarkers (ADAMTS-13 and anti-ADAMTS-13 immunoglobulins, classes and subclasses) and their potential relationship with prognosis. PATIENTS/METHODS In 115 patients with TTP, we assessed the association between levels of these biomarkers and the severity of acute episodes; we analysed also the hazard ratio (HR) and 95% confidence interval (CI) of recurrence in association with biomarkers levels retrieved at the previous acute episode or during remission, using Cox regression models. RESULTS During the acute phase, higher IgA, IgG1 and IgG3 titers showed the strongest association with acute episode severity. In the survival analyzes, the only biomarker significantly associated with a high hazard of recurrence after an acute episode was the presence of IgG. Conversly, low ADAMTS-13 activity or antigen levels (<10%), the presence of ADAMTS-13 inhibitor or IgG during remission were all significantly associated with a higher hazard of recurrence. CONCLUSIONS Both the Ig class and subclass are of predictive value for acute episode severity in patients with TTP. Although markers that could predict the risk of recurrence in the acute phase are limited, a thorough assessment of ADAMTS-13-related parameters during remission is warranted.

Abstract
BACKGROUND Posaconazole is effective as primary antifungal prophylaxis of invasive fungal diseases in patients with acute myeloid leukemia. DESIGN AND METHODS The impact of primary antifungal prophylaxis administered during front-line chemotherapy for acute myeloid leukemia was evaluated by comparing 58 patients who received oral amphotericin B (control group) to 99 patients who received oral posaconazole (posaconazole group). The primary endpoint was the incidence of proven/probable invasive fungal diseases. Secondary endpoints included incidence of invasive aspergillosis, survival at 4 and 12 months after the diagnosis of acute myeloid leukemia and costs. RESULTS Proven/probable invasive fungal diseases were documented in 51.7% of patients in the control group and in 23.2% in the posaconazole group (P=0.0002). Invasive aspergillosis was documented in 43% of patients in the control group and in 15% in the posaconazole group (P=0.002). No survival difference was observed in patients aged over 60 years. In patients aged 60 years or less, a statistically significant survival advantage was observed at 4 months, but no longer at 12 months, in the posaconazole group (P=0.03). It was calculated that in the posaconazole group there was a mean 50% cost reduction for the antifungal drugs. CONCLUSIONS Primary antifungal prophylaxis with posaconazole during front-line chemotherapy was effective in preventing invasive fungal diseases in a "real-life" scenario of patients with acute myeloid leukemia, resulted in an early but transitory survival advantage in younger patients and was economically advantageous.

Abstract
We have treated 20 patients, affected by acute myelogenous leukemia in advanced phase of the disease, with intravenous high-dose recombinant interleukin-2 (IL2) as induction treatment, achieving a complete remission (CR) in 11/20 of patients (55%). All CR patients were planned to receive a maintenance program with lower subcutaneous doses of IL2 until relapse. Currently, 5/11 patients are alive in continuous complete remission with a minimum follow-up of 9 years from IL2 induction. In the aim to investigate the treatment's side-effects during or after prolonged IL2 therapy, we decided to submit these patients to a clinical and immunological evaluation. Four patients have been evaluated as one, who independently stopped IL2 after 6 years, refused the check-up. No organ-specific treatment sequelae that may decrease the quality of life or may be life-threatening were found, concerning renal, liver and cardiovascular function. Endocrine abnormalities were detected in three patients, the most serious being a severe hypothyroidism, which prompted cessation of IL2 maintenance after 6 years and required thyroid supplementation treatment. Immunological studies were carried out prior to the last IL2 cycle and showed high levels of CD3-positive T cells expressing the IL2 receptor alpha chain (CD25), both in the peripheral blood and in the bone marrow. Our study shows that low-dose IL2 can be given for a prolonged period of time without serious organ-specific late sequelae and with a good quality of life.

Abstract
BACKGROUND AND OBJECTIVES Neurologic symptoms are present in 60% of patients with thrombotic thrombocytopenic purpura (TTP) on initial examination and ultimately develop in about 90% of cases during the course of the disease. Despite central nervous system involvement being frequent, abnormalities in the brain of patients with TTP are infrequent on neuroimaging (CT/MRI) and neurophysiologic (EEG) evaluation, often reversible and mainly limited to symptomatic stages of the disease. The aim of our study was to establish the value of a complete neurologic screening as part of the work up of TTP. DESIGN AND METHODS We prospectively evaluated 16 TTP patients, performing serial neurologic, neuroimaging and EEG examinations, independently of the presence of an objective central nervous system involvement. RESULTS Our study shows that a complete neurologic evaluation is of modest help in improving the diagnosis of TTP, but may be useful for the neurologic management. INTERPRETATION AND CONCLUSIONS Accurate neuroimaging and, especially, EEG evaluation and monitoring allowed us to identify patients who could benefit from anticonvulsive therapy, avoiding the unnecessary administration of the latter. The prognostic utility of complete neurologic screening in TTP remains to be conclusively demonstrated in larger prospective neurologic studies.

Abstract
In the bone marrow transplant setting, several authors hypothesized that severely overweight patients are at increased risk of transplant-related toxicity, but different definitions of obesity, different body weight groupings and heterogeneous samples of patients were analyzed. To overcome these limitations, we retrospectively considered a homogeneous group of 54 patients (median age 36.5 years), with a diagnosis of de novo acute myeloid leukemia (AML), autografted in first complete remission (CR) with the Bu-Cy2 conditioning regimen, dosed on actual body weight. Patients were classified into three groups (obese, non-obese, underweight) using body mass index (BMI = kg/m(2)); for each group we analyzed transplant-related toxicity and mortality, overall survival and disease-free survival (OS/DFS). In spite of the relatively small number of patients, in our results high BMI appears a predictive factor for an increase of treatment-related toxicity and mortality. Moreover, 30 (55%) patients are currently alive in continuous CR, and after a median follow-up of 76.5 months (range 14-137) statistically significant differences in OS and DFS were detected between obese and non-obese groups (P = 0.012 and 0.021, respectively). Our study suggests that obesity may represent an independent risk factor for autograft in AML and further investigations are warranted.

Abstract
Extensive studies have tested the clinical impact of double and triple sequential transplants as front-line therapy in MM, following the suggestion that dose escalation can overcome the marked drug resistance characteristic of this disease, but the superiority of such approaches vs one single transplant has still to be demonstrated. The aim of our study was to evaluate the feasibility and efficacy of high-dose idarubicine intensification of a standard busulphan-melphalan conditioning regimen in MM. Twenty-eight patients (median age 55 years) with sensitive disease received PBSCT after high-dose idarubicine combined with busulphan and melphalan and followed by s.c. rhG-CSF until PMN recovery. The most severe toxicity was represented by oral mucositis which resolved with hemopoietic reconstitution. Overall response and CR rate were 52% and 40%, respectively. Currently, 36 patients are alive and 19 are progression-free a median of 20 months (12-36) from transplant. The 3-year projected probability of progression-free survival for patients transplanted after first-line treatment is 60%. The combination of Ida/Bu/Melph appears a promising alternative regimen for PBSCT in myeloma, with low transplant-related toxicity and fast hematological recovery. Long-term follow-up and a prospective randomized study, now ongoing, will probably clarify whether an idarubicine-intensified regimen will result in superior outcomes to conventional conditioning and even be comparable to a double consecutive transplant program.
