Over the past 33 years, 153 cases of HCC were reported in patients with thalassemia, mainly in Italy, and Greece. Among HCV-infected patients additional factors promoting development of&nbsp; HCC, included: advanced age, male sex, chronic hepatitis B (CHB) coinfection, and iron overload. For early diagnosis of HCC sequential ultrasound screening&nbsp; is recommended&nbsp; especially for thalassemia patients with chronic hepatitis C (CHC), that coincide with (one or more) additional risk factors for HCC. &nbsp;Here we report also the preliminary data of thalassemic patients, above the age of 30 years, followed in 13 different centers. The total number of enrolled patients was 1,313 (males: 612 and 701 females). The prevalence of HCC in thalassemia major patients [characterized by transfusion-dependency (TDT)] and thalassemia intermedia [characterized by nontransfusion dependency (NTDT)] was 1.68 % and 1.98 % ,respectively The lowest age at diagnosis was 36 years in TDT and 47 years in NTDT patients.We hope that our review can be used to develop more refined and prospective analyses of HCC magnitude and risk in patients with thalassemia, and to define specific international guidelines to support clinicians for an early diagnosis and treatment of HCC in thalassemic patients.</p> 2020-01-01T00:00:00+00:00 Copyright (c) 2020 Vincenzo De Sanctis MOLECULAR MECHANISMS OF INHIBITOR DEVELOPMENT IN HEMOPHILIA 2020-02-27T12:26:11+00:00 Davide Matino Paul Tieu Antony Chan <p>The development of neutralizing antibodies in hemophilia is a serious complication of factor replacement therapy. These antibodies, also known as “inhibitors”, significantly increase morbidity within the hemophilia population and lower the quality of life for these patients. People with severe hemophilia A have an overall 25-40% lifetime risk of inhibitor development, compared to that of 5-15% lifetime risk in those with moderate/mild hemophilia A. The risk is lower in hemophilia B population (about 1-5%) and occurrence of inhibitors is almost only seen in patients with severe hemophilia B. The understanding of the pathophysiological mechanism leading to the development of inhibitors in patients with hemophilia has improved considerably over the last 2 decades. Identification of early biomarkers which predict inhibitor development in previously untreated patients with hemophilia will assist in risk identification and possible early intervention strategies. In this review, we aim to summarize the molecular mechanisms of inhibitor development in hemophilia and to identify potential areas in need of further investigation.</p> 2020-01-01T00:00:00+00:00 Copyright (c) 2019 Davide Matino, Paul Tieu, Dr., Antony Chan THE HISTORY OF DEFERIPRONE (L1) AND THE COMPLETE TREATMENT OF IRON OVERLOAD IN THALASSAEMIA 2020-02-27T12:25:23+00:00 George J Kontoghiorghes Marios Kleanthous Christina N. Kontoghiorghe <p>Deferiprone (L1) was originally designed, synthesised and screened in vitro and in vivo in 1981 by Kontoghiorghes G J following his discovery of the novel alpha-ketohydroxypyridine class of iron chelators (1978-1981), which were intended for clinical use. The journey through the years for the treatment of thalassaemia with L1 has been a very difficult one with intriguing turn of events, which continue until today. Despite many complications, such as the wide use of L1 suboptimal dose protocols, the aim of chelation therapy- namely the complete removal of excess iron in thalassaemia major patients, has been achieved following the introduction of specific L1 and L1/deferoxamine combinations. Many such patients continue to maintain normal iron stores. As a result of the introduction of L1, thalassaemia has changed from a fatal to a chronic disease and thalassaemia patients are active professional members in all sectors of society, have their own families with children and grandchildren and their lifespan is approaching that of normal individuals. No changes in the low toxicity profile of L1 have been observed in more than 30 years of clinical use. Thousands of thalassaemia patients are still denied the cardioprotective and other beneficial effects of L1 therapy. The safety of L1 in thalassaemia and other non-iron loaded diseases resulted in its selection as one of the leading therapeutics for the treatment of Friedreich’s ataxia, pantothenate kinase-associated neurodegeneration and other&nbsp;similar cases. There are also increasing prospects for the application of L1 as a main, alternative or adjuvant therapy in many pathological conditions including cancer, infectious diseases and as a general antioxidant for diseases related to free radical pathology.</p> 2020-01-01T00:00:00+00:00 Copyright (c) 2020 George J Kontoghiorghes, Marios Kleanthous, Christina N. Kontoghiorghe THE EVOLVING PHARMACOTHERAPEUTIC LANDSCAPE FOR THE TREATMENT OF SICKLE CELL DISEASE 2020-02-27T12:25:17+00:00 Samir Ballas <p>Sickle cell disease (SCD) is an extremely heterogeneous disease that has been associated with global morbidity and early mortality. More effective and inexpensive therapiesare needed. During the last five years the landscape of the pharmacotherapy of SCD has changed dramatically. Currently, there are at least 50 drugs that have been used or under consideration to use for the treatment of SCD. These fall into 3 categories: the first category includes the three drugs (Hydroxyurea, L-Glutamine and Crizanlizumab tmca) that have been approved by the United States Food and Drug Administration (FDA) based on successful clinical trials. The second category includes 22 drugs that failed, discontinued or terminated for now and the third category includes 25 drugs that are actively being considered for the treatment of SCD. New therapies targeting multiple pathways in its complex pathophysiology have been achieved or are under continued investigation. The emerging trend seems to be the use of multimodal drugs (i.e. drugs that have different mechanisms of action) to treat SCD similar to the use of multiple chemotherapeutic agents to treat cancer.</p> 2020-01-01T00:00:00+00:00 Copyright (c) 2020 Samir Ballas FEBRILE NEUTROPENIA IN ACUTE LEUKEMIA. EPIDEMIOLOGY, ETIOLOGY, PATHOPHYSIOLOGY AND TREATMENT 2020-02-27T12:26:17+00:00 Bent-Are Hansen Øystein Wendelbo Øyvind Bruserud Anette Lodvir Hemsing Knut Anders Mosevoll Håkon Reikvam <p>Acute leukemias are a group of aggressive malignant diseases associated with a high degree of morbidity and mortality. An important cause of both the latter is infectious complications. Patients with acute leukemia are highly susceptible to infectious diseases due to factors related to the disease itself, factors attributed to treatment, and specific individual risk factors in each patient. Patients with chemotherapy-induced neutropenia are at particularly high risk, and microbiological agents include viral, bacterial and fungal agents. The etiology is often unknown in infectious complications, although adequate patient evaluation and sampling have diagnostic, prognostic and treatment-related consequences. Bacterial infections include a wide range of potential microbes, both Gram-negative and Gram-positive species, while fungal infections include both mold and yeast. A recurring problem is increasing resistance to antimicrobial agents, and in particular, this applies to extended-spectrum beta-lactamase resistance (ESBL), <em>Pseudomonas aeruginosa</em>, methicillin-resistant <em>Staphylococcus aureus</em> (MRSA), vancomycin-resistant <em>Enterococcus</em> (VRE) and even carbapenemase-producing <em>Enterobacteriaceae</em> (CPE). International guidelines for the treatment of sepsis in leukemia patients include the use of broad-spectrum Pseudomonas-acting antibiotics. However, one should implant the knowledge of local microbiological epidemiology and resistance conditions in treatment decisions. Here, we discuss infectious diseases in acute leukemia with a major focus on febrile neutropenia and sepsis, and we problematize the diagnostic, prognostic, and therapeutic aspects of infectious complications in this patient group. Meticulously and thorough clinical and radiological examination combined with adequate microbiology samples are cornerstones of the examination. Diagnostic and prognostic evaluation includes patient review according to the multinational association for supportive care in cancer (MASCC) and sequential organ failure assessment (SOFA) scoring system. Antimicrobial treatments for important etiological agents are presented. The main challenge for reducing the spread of resistant microbes is to avoid unnecessary antibiotic treatment, but without giving to narrow treatment to the febrile neutropenic patient that reduce the prognosis.</p> 2019-12-30T21:11:05+00:00 Copyright (c) 2020 Bent-Are Hansen, Øystein Wendelbo, Øyvind Bruserud, Anette Lodvir Hemsing, Knut Anders Mosevoll, Håkon Reikvam CURRENT ISSUES AND OPTIONS FOR HORMONAL CONTRACEPTION IN ADOLESCENTS AND YOUNG ADULT WOMEN WITH SICKLE CELL DISEASE: AN UPDATE FOR HEALTH CARE PROFESSIONALS 2020-04-28T17:02:23+00:00 Vincenzo De Sanctis <p><strong>Abstract.</strong> Women with sickle cell disease (SCD) are of particular concern due to the significantly increased risk of pregnancy-related morbidity, mortality, and adverse outcomes. They have limited knowledge of the risks of pregnancy and childbirth as well as of the benefits and risks from the use of contraceptives. Thus, there is urgent need for appropriate information about reproductive family planning to reduce unintended pregnancy. Any decision regarding the use of contraceptives has to be based on the efficacy and the risks and benefits of the method used. Both the World Health Organization (WHO) and the Center for Disease Control and Prevention (CDC) have developed, published, and updated evidence-based guidelines for medical providers for the use of contraceptives in patients with specific medical chronic conditions. This article provides an overview of the present knowledge for the use of contraceptives in women with SCD. We believe that the collaboration between health care professionals (hematologists, obstetricians, endocrinologists, and primary care providers) can play a major role in identifying the safer contraceptive method to abolish the risks of unintended pregnancy and preserve the health status of patients with SCD.</p> 2020-04-27T22:21:53+00:00 Copyright (c) 2020 Vincenzo De Sanctis IRON DEFICIENCY ANEMIA IN CHILDREN RESIDING IN HIGH AND LOW-INCOME COUNTRIES: RISK FACTORS, PREVENTION, DIAGNOSIS AND THERAPY 2020-07-06T08:23:45+00:00 ELPIS MANTADAKIS <p><span lang="EN-US">Iron deficiency and iron deficiency anemia (IDA) affect approximately two billion people worldwide and most of them reside in low- and middle-income countries. In these countries, additional causes of anemia include parasitic infections like malaria, other nutritional deficiencies, chronic diseases, hemoglobinopathies and lead poisoning. Maternal anemia in resource-poor nations is associated with low birth weight, increased perinatal mortality and decreased work productivity. Maintaining a normal iron balance in these settings is challenging, as iron-rich foods with good bioavailability are of animal origin that are expensive and/or available in short supply. Apart from infrequent consumption of meat, inadequate vitamin C intake and diets rich in inhibitors of iron absorption are additional important risk factors for IDA in low-income countries. In-home iron fortification of complementary foods with micronutrient powders has been shown to effectively reduce the risk of iron deficiency and IDA in infants and young children in developing countries but is associated with unfavorable changes in gut flora and induction of intestinal inflammation that may lead to diarrhea and hospitalization. In developed countries, iron deficiency is the only frequent micronutrient deficiency. In the industrialized world, IDA is more common in infants beyond the sixth month of life, in adolescent females with heavy menstrual bleeding, in women of childbearing age and elderly people. Other special at-risk populations for IDA in developed countries are regular blood donors, endurance athletes and vegetarians. Several medicinal ferrous or ferric oral iron products exist, and their use is not apparently associated with harmful effects on the overall incidence of infectious illnesses in sideropenic and/or anemic subjects. Further research is needed to clarify the risks and benefits of supplemental iron for children exposed to parasitic infections in the third world, and for children genetically predisposed to iron overload.</span></p> 2020-06-28T11:28:10+00:00 Copyright (c) 2020 ELPIS MANTADAKIS CHILDREN IN CORONAVIRUSES’ WONDERLAND: WHAT CLINICIANS NEED TO KNOW 2020-07-06T08:30:44+00:00 Giuseppe Lassandro Valentina Palladino Anna Amoruso Viviana Palmieri Giovanna Russo Paola Giordano <p>Human coronaviruses (HCoVs) commonly cause mild upper-respiratory tract illnesses but can lead to more severe and diffusive diseases. A variety of signs and symptoms may be present, and infections can range in severity from common cold and sore throat to more serious laryngeal or tracheal infections, bronchitis, and pneumonia. Among the seven coronaviruses that affect humans, (SARS)-CoV, the Middle East respiratory syndrome (MERS)-CoV and the most recent coronavirus disease 2019 (COVID-19) represent potential life-threatening diseases worldwide. In adults they may cause severe pneumonia that evolve in distress respiratory syndrome and multiorgan failure with a high mortality rate. Children appear to be less susceptible to develop severe clinical disease and present usually with mild and aspecific symptoms similar to other respiratory infections typical of childhood. However, some children such as infants, adolescents or those with underlying diseases may be more at-risk categories and require greater caution from clinicians. Available data on pediatric coronavirus infections are rare and scattered in the literature. The purpose of this review is to provide to clinicians a complete and updated panel useful to recognize and characterize the broad spectrum of clinical manifestations of coronavirus infections in the pediatric age.</p> 2020-06-28T11:29:36+00:00 Copyright (c) 2020 Giuseppe Lassandro, Valentina  Palladino, Anna Amoruso, Viviana Palmieri, Giovanna Russo, Paola Giordano COBALAMIN DEFICIENCY IN THE ELDERLY 2020-07-06T08:45:56+00:00 Giacomo Marchi Fabiana Busti Acaynne Lira Zidanes Alice Vianello Domenico Girelli <p>Older people are at risk for cobalamin (vitamin B<sub>12</sub>) deficiency because of a number of common disorders (e.g. autoimmune gastritis) and drugs (e.g. antacids) that may alter its absorption and utilization. The prevalence of cobalamin deficiency increases with age, resulting particularly elevated in frail and institutionalized subjects. At variance with common sense, the diagnosis is far from simple and requires a high degree of suspicion, due to heterogeneity and non-specificity of the signs and symptoms, ranging from macrocytosis (with or without anemia) to neuropsychiatric manifestations, that characterize several other aging-related disorders, like hematological malignancies, diabetes, hypothyroidism or vasculopathies. Furthermore, the detection of low levels of serum vitamin B<sub>12</sub> appears poorly sensitive and specific. Other biomarkers, like serum homocysteine or methylmalonic acid, have improved the diagnostic possibilities but are expensive, not widely available and may be influenced by some confounders (e.g. folate deficiency, or chronic renal failure). Early recognition and treatment are crucial, since a proportion of patients develop severe complications, such as bone marrow failure and irreversible neurological impairment. High-dose oral treatment has proven to be as effective as the parenteral route even in subjects with malabsorption, ensuring the complete resolution in the majority of cases. In this review, we trace the essential role of cobalamin in humans, the possible causes and impact of deficiency, the diagnostic challenges and the therapeutic options, between old and emerging concepts, with a particular focus on the elderly.</p> 2020-06-28T12:18:15+00:00 Copyright (c) 2020 Giacomo Marchi, Fabiana Busti, Acaynne Lira Zidanes, Alice Vianello, Domenico Girelli ACQUIRED HAEMOPHILIA A: AN INTRIGUING DISEASE 2020-07-06T10:33:18+00:00 Maria Gabriella Mazzucconi Erminia Baldacci Antonietta Ferretti Cristina Santoro <p>Acquired Haemophilia A is a rare acquired bleeding disorder caused by autoantibodies directed against Factor VIII, which neutralize FVIII activity. These inhibitors differ from alloantibodies against FVIII which can occur in congenital Haemophilia A after repeated exposures to plasma-derived or recombinant FVIII products. In most cases the disease occurs suddenly in subjects without personal or familiar history of bleedings, with symptoms that may be mild, moderate or severe. However, only laboratory alterations are present in&nbsp; &nbsp;̴ 30% of patients. The incidence varies from 1 to 4 cases per million/year; more than 80% of patients are elderly, males and females are similarly affected. There is a small peak of incidence related to pregnancy in young women aged 20–40 years. The disease may be underdiagnosed in the elderly. The diagnostic algorithm is based on an isolated prolonged activated partial thromboplastin time, normal thrombin time, absence of Lupus Anticoagulant and a mixing test that reveals the presence of an inhibitor: the finding of reduced FVIII activity and the detection of neutralising autoantibodies against FVIII lead to diagnosis. The disease is idiopathic in &nbsp;&nbsp;44%-63% of cases, while in the others etiological factors are present. Bleeding prevention and treatment are based on therapeutic tools as bypassing agents, recombinant porcine FVIII concentrate or, in a limited number of cases, FVIII concentrates and desmopressin. As soon as the diagnosis has been made, immunosuppressive therapy must be started to eradicate the inhibitor. Better knowledge of the disease, optimal management of bleeding and eradication of the inhibitor have significantly reduced morbidity and mortality in most patients.&nbsp;</p> <p>&nbsp;</p> <p>Keywords: autoantibodies against FVIII, bleeding symptoms, bleeding treatment, eradication therapy.&nbsp;</p> 2020-06-28T12:28:57+00:00 Copyright (c) 2020 Maria Gabriella Mazzucconi, Erminia Baldacci, Antonietta Ferretti, Cristina Santoro - KAWASAKI DISEASE AS THE IMMUNE-MEDIATED ECHO OF A VIRAL INFECTION 2020-07-06T10:51:52+00:00 Donato Rigante <p>Although etiology of Kawasaki disease remains elusive, the available evidence indicates that the primum movens might be a dysregulation of immune responses to various microbes, i.e. a kind of immune-mediated response induced by a viral infection.

This retrospective study aims to investigate the characteristics and prognostic factors of candidemia among leukemia patients in a Chinese chemotherapy center.</p> <p>From 2009 to 2015, 30 isolates of candidemia were detected in 19 patients with acute leukemia after chemotherapy. The overall incidence of candidemia was 2.12 episode per 1000 admissions<em>. </em><em>Candida tropicalis</em> was the most common <em>Candida</em> species (n = 17; 89.5%), followed by <em>Candida albicans</em> (n = 2; 10.5%). The most common underlying disease was acute myeloid leukemia (94.7%) and induction chemotherapy phase was the most susceptible stage. The vast majority of candidal infections are endogenous rather than central venous catheter-related. The overall 30-day crude mortality rate was 31.6%.

Early diagnosis followed by rapid antifungal treatment remains the cornerstone of successful management. Catheter removal should be considered on an individual basis. The widespread use of newer antifungal agents as prophylaxis among patients with acute leukemia may result in a decreased candidemia incidence.</p> 2020-01-01T00:00:00+00:00 Copyright (c) 2020 Xiaoyuan Gong, mianzeng yang, Dong Lin, Hui Wei, Ying Wang, Bingchen Liu, Chunlin Zhou, Kaiqi Liu, Shuning Wei, Benfa Gong, Guancji Zhang, Yuntao Liu, Yan Li, Xingli Zao, Shaowei Qiu, Ruxia Gu, Yingchang Mi, Jianxiang Wang THE PROGNOSTIC SIGNIFICANCE OF TET2 SINGLE NUCLEOTIDE POLYMORPHISM IN EGYPTIAN CHRONIC MYELOID LEUKEMIA 2020-02-27T12:26:05+00:00 Enas A Dammag Nahla A.M. Hamed Nabil A El Halawani Heba S Kassem Mona W Ayad <p><strong>Background: </strong>Chronic myeloid leukemia (CML) is a myeloproliferative neoplasm. The pathogenesis of CML is based on the oncoprotein termed BCR‐ABL1. TET2 initiates DNA demethylation and is frequently mutated in hematological malignancies including CML.<sup>(1)</sup> The relation between TET2 acquisition and CML transformation and/or imitinab resistance is needed to be investigated. <strong><sup>(2)</sup></strong></p> <p><strong>Aim:</strong> To evaluate Ten Eleven Translocation 2 gene (TET2) single nucleotide polymorphism (SNP) (rs2454206, rs34402524, rs61744960) in chronic myeloid leukemia (CML) in relation to the disease prognostic criteria.</p> <p><strong>Materials &amp; Method:</strong> The study included 84 subjects; 54 CML in chronic phase and 30 healthy subjects as control group matched for age and sex. Routine investigations including CBC, bone marrow aspiration, biochemical investigations and molecular study were performed in CML patients to identify the disease stage. DNA extraction and SNP assay for TET2 gene polymorphism was done using (Thermo-Fisher predesigned SNP, USA) PCR prism 7500.</p> <p><strong>Results:</strong> The mean age was 45.98±15.7 yrs in CML patients and&nbsp;&nbsp; 39.3±6.587 yrs in control group (p&gt;0.05). TET2 SNP rs 34402524 was either heterozygous and homozygous in CML (48%,and 46.2%) but was mainly homozygous among control (80%) group (p=0.012). TET2 SNP rs 2454206 cases within CML (65.4%) and control (63.3%) group had wild patterns (p=0.046). TET2 SNP rs 61744960 showed a homozygous pattern among all groups (CML and control) showing no statistical significance (p=0.528). TET2 SNP in CML cases did not alter the prognostic criteria as no statistical significance was noted (p&gt;0.05) yet, it was significantly related to spleen size in rs 34402524 where homozygous group had huger sizes and higher BCR-ABL1 levels 6 months after starting TKIs (p&lt;0.05).</p> <p><strong>Conclusions/Recommendation:</strong> TET2 SNP is a common in Egyptian chronic myeloid leukemia. TET2 SNP rs 3442524 was associated with huger spleen size and higher BCR-ABL1 levels after 6 months of starting TKIs suggesting disease progression.</p> 2020-01-01T00:00:00+00:00 Copyright (c) 2020 Enas A Dammag, Nahla A.M.

We evaluated the clinical diagnostic value of miRNA-181a-3p in predicting prognosis and outcomes in patients with AML.</p> <p><strong>Methods: </strong>A total of 119 newly diagnosed adult patients with AML and 60 healthy controls were recruited. Blood specimens were obtained from all AML patients at diagnosis, and 10 blood specimens were obtained on day 28 after induction chemotherapy. The controls also provided blood samples. MiR-181a-3p expression was quantified by PCR, and relative&nbsp;miRNA&nbsp;expression&nbsp;was determined using the comparative Ct method.</p> <p><strong>Results:</strong> Compared with healthy controls, the expression of miRNA-181a-3p was significantly increased in patients with AML. MiR-181a-3p expression could be used to discriminate AML patients from controls, with up-regulated expression correlating with favorable prognosis. Moreover, miRNA-181a-3p expression was significantly decreased in patients who achieved a complete response after induction chemotherapy. The multivariate Cox analysis highlighted the prognostic value of miR-181a-3p for patients with AML.</p> <p><strong>Conclusions:</strong> MiR-181a-3p may be clinically useful as a disease marker for AML, and enhanced the prediction of patient outcomes to chemotherapy.</p> 2020-02-26T14:27:22+00:00 Copyright (c) 2020 Xiaoling Ma The PARTIAL ACHIEVEMENT OF THE 90-90-90 UNAIDS TARGET IN A COHORT OF HIV INFECTED PATIENTS FROM CENTRAL ITALY. 2020-02-27T12:25:04+00:00 Elisabetta Schiaroli <p>Despite progress in the prevention and treatment of HIV, persistent issues concerning the evaluation of continuum in care from the serological diagnosis to virologic success remain.</p> <p>Considering the UNAIDS target 90-90-90 for 2020 for treatment and viral suppression of people living with HIV (PLVH), our purpose was to verify if, starting from diagnosis, the viral suppression rate of our cohort of new PLWH satisfied the above targets.</p> <p>The aim of this retrospective study was to compare 2005-2017 data collected at the Perugia Infectious Diseases Clinic with the 2020 UNAIDS 90 targets and to identify risk factors that could be associated with failure to reach these targets.</p> <p>Methods:&nbsp; We included all patients aged ≥15 undergoing HIV test at our clinic between January 2005 and December 2017. We evaluated the unclaimed tests, linkage to care, retention in ART and the viral suppression at 1 and 2 years from starting ART. Data were analyzed between Italians and foreigners.</p> <p>Results: We observed 592 new diagnoses for HIV infection: 61.4% on Italian-natives, 38.5% on foreigners. Considering the continuum of care from diagnosis, 88 (15%) PLWHIV were lost to engagement in care: 55 (9.2%) patients didn’t withdraw the test and 33 (5.5%) &nbsp;didn’t link to care.</p> <p>An antiretroviral treatment was started only on 78.8% of the new diagnoses (467/592) and a viral suppression was obtained at 2 years on 82% of PLWH who had started ART (383/467) namely only 64.7% of the new diagnoses instead of the hoped-for 81% of the UNAIDS target. We found no significant differences between Italians and foreigners</p> <p>Conclusions</p> <p>UNAIDS goal was very far to be reached. The main challenges were unreturned tests as well as the retention in ART.

In 49 of 55 patients who were tested both before and after chemotherapy for at least a pathogen, the loss of immunity for HBV, rubella, VZV, measles, mumps, polioviruses and C. tetani was respectively 39%, 43%, 38%, 42%, 32%, 33%, and 80%. A low number of B-lymphocytes was associated with the loss of immunity against measles (p=0.04) whereas a high number of CD8+ T-lymphocytes was associated with the loss of immunity against VZV (p=0.03). A single booster of vaccine dose resulted in a seroprotection for HBV, rubella, VZV, measles, mumps, polioviruses, C. tetani and S. pneumoniae in 67%, 83%, 80%, 67%, 33%, 100%, 88% and 67% of patients, respectively. Conclusions: We confirm that seroprotection for vaccine-preventable diseases is affected by treatment for pediatric malignancy. A single booster dose of vaccine might be a practical way to restore vaccine immunity in patients after chemotherapy.</div> <div>&nbsp;</div> 2020-02-26T14:43:49+00:00 Copyright (c) 2020 Chiara Garonzi, Rita Balter, Gloria Tridello, Anna Pegoraro, Manuela Pegoraro, Monia Pacenti, Novella Scattolo, Simone Cesaro DEVELOPMENT OF AN IMPROVED EPSTEIN-BARR VIRUS (EBV) NEUTRALIZING ANTIBODY ASSAY TO FACILITATE DEVELOPMENT OF A PROPHYLACTIC GP350-SUBUNIT EBV VACCINE 2020-03-02T16:57:24+00:00 Hui Liu Lorraine Gemmell Rui Lin Fengrong Zuo Henry H. Balfour Jennifer C. Woo Gregory M. Hayes <p>No licensed vaccine is available for prevention of EBV-associated diseases, and robust, sensitive, and high-throughput bioanalytical assays are needed to evaluate immunogenicity of gp350 subunit-based candidate EBV vaccines. Here we have developed and improved analytical tools for such a vaccine’s pre-clinical and clinical validation including a gp350-specific antibody detection assay and an EBV-GFP based neutralization assay for measuring EBV specific antibodies in human donors. The sensitivity of our previously published high-throughput EBV-GFP fluorescent focus (FFA)-based neutralization assay was further improved when guinea pig complement was supplemented using a panel of healthy human sera. Anti-gp350 antibody titers, which were evaluated using an anti-gp350 IgG ELISA assay optimized for capture and detection conditions, were moderately correlated to the FFA-based neutralization titers. Overall, these sensitive, and high-throughput bioanalytical assays are capable of characterizing the serologic response to natural EBV infection, with applications in evaluating EBV antibody status in epidemiologic studies and immunogenicity of candidate gp350-subunit EBV vaccines in clinical studies.</p> 2020-02-26T14:46:06+00:00 Copyright (c) 2020 Hui Liu, Henry H.

Hayes DISCOVERY OF TYPE 3 VON WILLEBRAND DISEASE IN A COHORT OF PATIENTS WITH SUSPECTED HEMOPHILIA A IN CÔTE D’IVOIRE 2020-03-02T16:54:22+00:00 Adia Eusèbe Adjambri Sylvie Bouvier Roseline N'guessan Emma N’draman-Donou Mireille Yayo-Ayé Marie-France Meledje Missa Louis Adjé Duni Sawadogo <p><strong>Abstract</strong></p> <p><strong>Aim&nbsp;:</strong> Type 3 von Willebrand disease (VWD) is the most severe form of VWD, characterized by a near-total absence of von Willebrand factor (vWF) leading to a huge deficiency in plasmatic factor VIII (FVIII). VWD may be confused with hemophilia A, sometimes leading to misdiagnosis. The purpose of this work was to finalize the biological diagnosis of patients with FVIII activity deficiency in Abidjan, in order to guide the best type of management. <strong>Methods:</strong> We conducted a cross-sectional descriptive study from June 2018 to April 2019. Forty-nine patients, all of whom had lower FVIII levels or had been referred for bleeding disorder, were monitored in the clinical hematology service. Pro-coagulant activity of coagulation factors was performed in Abidjan. The assays for von Willebrand antigen and activity were performed at Nîmes University Hospital in France. <strong>Results:</strong> The mean age of patients was 13.8 years (1 – 65) and 86% were Ivorian. FVIII deficiency was discovered during a biological checkup, circumcision or post-traumatic bleeding, in 33%, 31% and 29% respectively. The FVIII level of patients was classified as severe (89.8%), moderate (8.2%) and mild (2%). Only one patient had a quantitative deficiency of von Willebrand factor (vWF: Ag &lt;3%) with undetectable von Willebrand factor activity (vWF: Ac) and an FVIII level &lt;1%. <strong>Conclusion:</strong> Not all of the constitutive deficits of FVIII are hemophilia A. It was very important to assess the Willebrand factor of these patients followed in Côte d'Ivoire for whom hemophilia A had been suspected.</p> 2020-02-26T15:22:13+00:00 Copyright (c) 2020 Adia Eusèbe Adjambri, Sylvie Bouvier, Roseline N'guessan, Emma N’draman-Donou, Mireille Yayo-Ayé, Marie-France Meledje, Missa Louis Adjé, Duni Sawadogo THALIDOMIDE FOR PATIENTS WITH THALASSEMIA INTERMEDIA: A RETROSPECTIVE MULTICENTER CLINICAL STUDY 2020-04-28T17:02:27+00:00 Kun Yang Yi Wu Yali Zhou Tianhong Zhou Li Wang Zhili Geng Xiaolin Yin <p><strong>Objective</strong><strong>: </strong>This study focused on the efficacy and safety of thalidomide for patients with thalassemia intermedia (TI) in a multicenter trial.</p> <p><strong>Methods</strong><strong>:</strong>Clinical and laboratory data of 62 patients subjected to thalidomide therapy in four centers were retrospectively analyzed. We evaluated the efficacy and safety of thalidomide in the short-term (three months) and long-term follow-up (12 and 24 months). Response to thalidomide was defined as follows: Main Responder (MaR) showing an increase in Hb level of &gt;2.0 g/dl or removal from blood transfusion and Minor Responder (MiR) achieving elevated hemoglobin (Hb) level of 1.0-2.0 g/dl or ≥50% reduction in blood transfusion frequency.</p> <p><strong>Results</strong><strong>:</strong>The overall response rate (ORR) of 62 patients with TI was 93.5% (58/62), with MaR and MiR rates accounting for 62.9% (39/62) and 30.6% (19/62) in short-term follow-up and 66.1% (41/62) and 27.4% (17/62) in long-term follow-up, respectively. The clinical response during long-term follow-up was maintained and the Hb level remained stable during the observation period. The response was still observed in patients with dose reduction despite a slight decrease in Hb level. However, Hb decreased rapidly to the baseline level after drug discontinuation. No effect of thalidomide on spleen size in nonsplenectomized patients was evident. Minimal side-effects were documented throughout, except peripheral neurotoxicity in one patient. Nevertheless, the mean serum ferritin (SF) level was significantly increased after treatment.</p> <p><strong>Conclusion:</strong> Thalidomide had significant therapeutic effects on patients with TI, and the response was sustained with acceptable short-term and long-term adverse reactions. While these preliminary results support the potential long-term efficacy and safety of thalidomide as a therapeutic agent for TI, several issues need to be addressed before its application in the clinic.</p> 2020-04-27T21:41:16+00:00 Copyright (c) 2020 Kun Yang, Yi Wu, Yali Zhou, Tianhong Zhou, Li Wang, Zhili Geng, Xiaolin Yin LYON-UNIVERSITY HOSPITAL EXPERIENCE WITH GEMTUZUMAB OZOGAMICIN THERAPY IN ACUTE MYELOID LEUKEMIA: A ‘REAL-LIFE’ STUDY 2020-06-09T17:32:46+00:00 Xavier Thomas Marica Laurino sandrine loron marie-virginie larcher gaëlle fossard mohamed elhamri alexandre deloire marie balsat fiorenza barraco hélène labussière sophie ducastelle myriam renault eric wattel maël heiblig gilles salles <p>One-hundred and four adults with newly diagnosed or relapsed/refractory acute myeloid leukemia (AML) were treated with fractionated doses of gemtuzumab ozogamicin (GO) at one-single French center over a 10-year period.

Such patients use iron chelators their whole lives, resulting in enormous treatment costs. This study analyses the cost-utility of these four regimens from the Chinese healthcare system perspective.</p> <p><strong>Methods:</strong> A Markov decision model was used over a 70-year time horizon and was populated using clinical data from a systematic literature review. We obtained utility data from local and previous research. Costs were estimated using Chinese national sources.</p> <p><strong>Results:</strong> From the base-case analysis results, DFP was the most cost-effective chelation regimen, followed by DFO+DFP, DFO and DFX. DFP had a 99.60%, 78.10% and 64.40% likelihood of being cost-effective versus DFX, DFO and DFO+DFP, respectively, at a payment threshold of 193,932.00 CNY/QALY.</p> <p><strong>Conclusions:</strong> DFP was the most cost-effective chelation regimen for β-thalassemia major patients, followed by DFO+DFP, DFO and DFX. Using DFP as the primary treatment regimen may potentially result in cost-savings and QALY gains for the Chinese healthcare system. To increase these benefits, the Chinese government and clinicians should lower drug costs, increase drug utility and reduce mortality and morbidity. Changes in influential parameters easily affect the results of DFO+DFP versus DFP and of DFP versus DFO; clinicians should focus on such parameters and adjust the regimens accordingly.</p> 2020-04-27T21:52:06+00:00 Copyright (c) 2020 Jialian Li CLINICAL USEFULNESS OF BROCHOALVEOLAR LAVAGE IN THE MANAGEMENT OF PULMONARY INFILTRATES IN ADULTS WITH HAEMATOLOGICAL MALIGNANCIES AND STEM CELL TRANSPLANTATION 2020-04-28T17:02:21+00:00 Laura Jorge Diego Torres Agustín Languasco Pablo Rodriguez Pablo Bonvehí Elena Temporiti Silvia Relloso Cristina Videla Fabián Herrera <p class="AbstractCxSpFirst"><span lang="EN-GB">Introduction: Pulmonary complications are frequent in patients with hematologic malignancies and stem cell transplantation.

We aimed to measure the HRQoL of transfusion dependent (TDT) and non-transfusion dependent (NTDT) of these pediatric patients at our institute.</p> <p><strong>Methods</strong><strong>: </strong>We included all patients 2 – 18 years old, with TDT and NTDT, using the Pediatric Quality of Life Inventory 4.0 Generic Core Scales (PedsQL) and the EuroQol Group’s Five Dimensions for Youth (EQ-5D-Y) instruments. Patients and caregivers responded as appropriate for age.</p> <p><strong>Results</strong><strong>: </strong>Mean PedsQL total summary scores (TSS) (SD) of child self-reports and parent proxy-reports were 81.00 (10.94) and 78.84 (16.72) from 150 participants. Mean EQ-5D-Y VAS (SD) for children was 89.27 (11.56) and 86.72 (10.62) for parent proxies. The most problematic EQ-5D-Y dimension was “having pain or discomfort”. These scores had significant correlations between child and parental proxy perspectives, as well as between the PedsQL and EQ-5D-Y.

Since vitamin D binding protein (VDBP) maintains bioavailability of vitamin D which binds to vitamin D receptor (VDR)-retinoid X receptor alpha (RXRA) heterodimer to exert its molecular actions, we speculated that vitamin D metabolic-axis expression signature and variants could be potential molecular candidates for bone turnover/disease in thalassemia. To this end, this study aims to analyze <em>VDR</em>/<em>RXRA </em>expression signature, and two <em>VDBP</em> variants in a pilot sample of Egyptian β-thalassemia children in correlation with bone mineral density (BMD).</p> <p><strong>Patients and methods:</strong> Forty-four β-thalassemia children and 40 unrelated controls were enrolled. The serum bone chemistry profile was measured. Peripheral blood mononuclear cells (PBMN) <em>VDR</em>/<em>RXRA </em>expression levels were quantified by Real-Time quantitative reverse transcription-polymerase chain reaction (qRT-PCR). <em>VDBP</em> rs7041 and rs4588 variants were identified by Real-Time allelic discrimination assay. All patients were subjected to lumbar-spine Dual-energy X-ray absorptiometry (DEXA).</p> <p><strong>Results:</strong> <em>VDR</em>/<em>RXRA</em> expressions were significantly higher in β-thalassemia children compared to controls (<em>P </em>= 0.001 and &lt;0.001, respectively) and showed higher values in β-thalassemia major relative to β-thalassemia intermedia. Expression levels of both genes were not associated with sex or BMD. However, <em>VDBP </em>rs4701 genotyping revealed lower BMD-L4 and a higher frequency of osteoporosis.</p> <p><strong>Conclusions:</strong> β-Thalassemia children had higher expression levels of PBMN <em>VDR</em>/<em>RXRA</em>. <em>VDBP </em>rs4701 variant was associated with osteoporosis in our β-thalassemia patients on vitamin D supplementation. Further large-scale studies in other ethnic populations are warranted.</p> 2020-06-28T09:29:45+00:00 Copyright (c) 2020 Shaimaa Sahmoud, Mostafa Ibrahim, Eman Toraih, Noha Kamel, Manal Fawzy, Samar Elfiky A SEROPREVALENCE OF HBV, HCV AND HIV-1 AND CORRELATION WITH MOLECULAR MARKERS AMONG MULTI-TRANSFUSED THALASSEMIA PATIENTS IN WESTERN INDIA 2020-07-06T07:59:42+00:00 Kanchan Mishra Avani Shah Krima Patel Kanjaksha Ghosh Sumit Bharadva <p><strong>Background: </strong>Blood transfusion is a lifesaving therapy for patients with hemoglobinopathies. However, the need of frequent transfusion carries the risk of transfusion-transmitted infections (TTIs). This study was aimed to determine the seroprevalence of Hep-B, Hep-C and HIV-1infections among the multi-transfused Beta-thalassemic patients and correlate the same with NAT testing.</p> <p><strong>Methods: </strong>Total 196 patients with Beta-thalassemia were included in the study. Patients were screened for the presence of viral markers by third generation ELISA test as well as for viral DNA/RNA by NAT.&nbsp;</p> <p><strong>Results:</strong> Among these 196 multi-transfused Beta-thalassemia patients, 32.1% were females and 67.8% were males. A total of 100 (51.1%) patients were found to be anti-HCV antibody reactive, while HCV-RNA was positive in 66 (33.7 %) of the 196 patients tested. There were 6 (3.1%) patients reactive for anti-HIV-1 antibody, while 8 (4.1%) were positive for HIV-RNA. There were only 3 (1.5%) patients that were found to be reactive for HBsAg, however 5 (2.5%) were positive for HBV-DNA. Two (1%) patients had co-infection of anti-HCV antibody and HBsAg,whereas 6 patients were found co-infected by NAT testing, in-which 3 (1.5%) were positive for HBV-DNA and HCV-RNA, 1 (0.5%) was positive for HIV-RNA and HBV-DNA, and 2 (1%) had co-infection of HIV-RNA and HCV RNA.</p> <p><strong>Conclusion: </strong>Prevalence of HCV among multi-transfused Beta-thalassemia patients is significantly higher than the normal population. On the other hand, the study showed low prevalence of HBV. Therefore, a follow-up schedule and administration of booster dose of HBV vaccine is strongly recommended for thalassemia patients. To the best of our knowledge, this is the foremost work that shows prevalence of HIV, HBV and HCV in thalassemia patients using both serology and molecular markers in Western India.</p> 2020-06-28T09:39:01+00:00 Copyright (c) 2020 Kanchan Mishra, Avani Shah, Krima Patel, Kanjaksha Ghosh, Sumit Bharadva A A Multicentre ICET-A Study of Confirmed SARS-CoV-2 Infection in Patients with Hemoglobinopathies: Preliminary Data from 10 Countries 2020-06-28T17:08:19+00:00 Vincenzo De Sanctis <p><strong>Objectives: </strong>This study aims to investigate, retrospectively, the epidemiological and clinical characteristics, laboratory results, radiologic findings and outcomes of novel coronavirus disease-19 (COVID-19) in patients with transfusion dependent β thalassemia (β-thalassemia major-TM), non-transfusion dependent β thalassemia (β-thalassemia intermedia -TI) and sickle cell disease (SCD). <strong>Design, setting: </strong>A total of 17 Centers, from 10 countries, following 9,499 patients with hemoglobinopathies participated in the survey. <strong>Main outcome measures: </strong>Clinical, laboratory and radiologic findings and outcomes of patients with COVID-19 were collected<strong> from m</strong>edical records and summarized. <strong>Results: </strong>A total of 13 patients, 7 with TM, 3 with TI and 3 with SCD, with confirmed COVID-19, were identified from 6 Centers from different countries. The overall mean age of patients was 33.7±12.3 years (range:13-66); 9/13 (69.2%) patients were females. The commonest symptoms in the 10 symptomatic patients were: fever (80%), cough (70%), headache (60%), fatigue (60%), gastrointestinal symptoms (diarrhea /vomiting/abdominal pain; 50%), tachypnea/dyspnea (40%), and sore throat (40%). Six patients had pneumonia (unilateral, bilateral or multiple opacity) and 4 needed oxygen therapy. An oxygen saturation ≤ 93% was documented in 3 patients at diagnosis. 6/10 patients had an exacerbation of anemia (2 with SCD, associated with back and chest pain in 1 patient), and 3 (&lt;30%) had a decreased absolute number of lymphocytes. Increased C-reactive protein and D-dimers were the most common laboratory findings (66.6 %). <strong>Conclusions: </strong>The clinical presentation for COVID-19 in patients with β-thalassemia and SCD varies. Patients with mild/ordinary COVID-19 infection appear to have clinical symptoms and laboratory findings common to other viral respiratory infections.

She had been treated with imatinib and had achieved major molecular remission, after which imatinib was intentionally discontinued and interferon-α treatment was initiated. After three failed cycles of artificial insemination with her husband’s semen, the patient underwent treatment with assisted reproductive technology. After two cycles of <em>in vitro</em> fertilization, two embryos (8-cell stage and blastocyst) were cryopreserved. The patient again had elevated <em>BCR/ABL</em> mRNA levels; thus, infertility treatment was discontinued. After 18 months of dasatinib treatment, major molecular remission was observed and the patient underwent vitrified–warmed embryo transfer with a single blastocyst. Thereafter, she became pregnant.
