The treating physician has now the opportunity to decide i) which patient can be still offered chemoimmunotherapy as salvage treatment, ii) which patient is a candidate to receiving at relapse continuous treatment with ibrutinib, idelalisib and rituximab or venetoclax and iii) which patient may benefit from a fixed-duration treatment using the BCL2 antagonist venetoclax in association with rituximab.</p> <p>Ibrutinib is the most actively investigated drug in R/R CLL and data at a 7-year follow-up were reported, showing durable efficacy and favorable efficacy profile. The patients with &nbsp;cardiac disease, hypertension and on anticoagulant therapy are not ideal candidates for continuous therapy with this agent. Idelalisib and rituximab was tested in patients with unfavorable characteristics including cytopenias. The short follow-up and treatment emergent adverse events limit its role to patients unlikely to get a benefit with other agents. Venetoclax and rituximab is the only effective chemo-free approach for the treatment of R/R with a fixed duration (up to 24 months) schedule capable of inducing deep &nbsp;responses in the majority of cases with a reassuring safety profile.</p> <p>While a deep knowledge of the growing body of scientific evidence is required to inform and guide the appropriate treatment choice and management, physicians cannot disregard the growing problem of sustainability</p> 2019-02-27T14:07:21+00:00 ##submission.copyrightStatement## NEW THERAPEUTIC OPTIONS FOR THE TREATMENT OF SICKLE CELL DISEASE 2019-10-21T16:36:52+00:00 Alessandro Matte Filippo Mazzi Enrica Federti Oliviero Olivieri Lucia De Franceschi <p>Sickle cell disease (SCD; ORPHA232; OMIM # 603903) is a chronic and invalidating disorder distributed worldwide, with high morbidity and mortality.&nbsp; Given the disease complexity and the multiplicity of pathophysiological targets, development of new therapeutic options is critical, despite the positive effects of hydroxyurea (HU), for many years the only approved drug for SCD.</p> <p>New therapeutic strategies might be divided into (1) pathophysiology-related novel therapies and (2) innovations in curative therapeutic options such as hematopoietic stem cell transplantation and gene therapy.

Even if this risk has decreased for NHL after the introduction of combination antiretroviral therapy (cART), they remain the most common AIDS-related cancer in the developed world. They are almost always of B-cell origin, and some specific lymphoma types are more common than others. Some of these lymphoma types can occur in both HIV-uninfected and infected patients, while others preferentially develop in the context of AIDS. HIV-associated lymphoma differ from lymphoma in the HIV negative population in that they more often present with advanced disease, systemic symptoms, and extranodal involvement and are frequently associated with oncogenic viruses (EBV and/or HHV-8). Before the introduction of cART, most of these patients could not tolerate the treatment strategies routinely employed in the HIV-negative population. The widespread use of cART has allowed for the delivery of full-dose and dose-intensive chemotherapy regimens with improved outcomes that nowadays can be compared to those seen in non-HIV infected patients. However, a great deal of attention should be paid to opportunistic infections and other infectious complications, cART-chemotherapy interactions, and potential cumulative toxicity. In the context of relatively sparse prospective and randomized trials, the optimal treatment of AIDS-related lymphomas remains a challenge, particularly in patients with severe immunosuppression. This paper will address epidemiology, pathogenesis, and therapeutic strategies in HIV-associated NHL and HL.</span></p> 2019-01-01T00:00:00+00:00 ##submission.copyrightStatement## PREGNANCY IN THALASSEMIA 2019-10-21T16:36:50+00:00 Raffaella Origa Federica Comitini <p>Therapeutic advances, including the availability of oral iron chelators and new non-invasive methods for early detection and treatment of iron overload, have significantly improved the life expectancy and quality of life of patients with thalassemia, with a consequent increase in their reproductive potential and desire to have children. Hundreds of pregnancies have been reported so far, highlighting that women carefully managed during preconception usually carry out a successful gestation and labour, both in case of spontaneous conception and use of assisted reproductive techniques. A multidisciplinary team including a cardiologist, an endocrinologist and a gynaecologist, with the supervision of an expert in beta-thalassemia should be involved.&nbsp;</p> <p>During pregnancy, a close follow-up of maternal disorders and of the baby's status is recommended. Haemoglobin should be maintained over 10 g/dL to to allow normal foetal growth. Chelators are not recommended during pregnancy; nevertheless, it may reasonable to consider restarting chelation therapy with desferrioxamine towards the end of the second trimester when the potential benefit outweighs the potential foetal risk.</p> <p>Women with non-transfusion-dependent thalassemia who have never previously been transfused or who have received only minimal transfusion therapy are at risk of severe alloimmune anaemia if blood transfusions are required during pregnancy. Since pregnancy increases the risk of thrombosis three-fold to four-fold and thalassemia is also a hypercoagulable state, the recommendation is to keep women who are at higher risk -such as those who are not regularly transfused and those splenectomised-&nbsp; on prophylaxis during pregnancy and during the postpartum period.</p> <p>&nbsp;</p> <p><strong>Keywords:</strong>Pregnancy, Thalassemia major, Thalassemia intermedia, Haemoglobin H disease, Counselling</p> 2019-02-26T21:19:11+00:00 ##submission.copyrightStatement## FAMILIAL MEDITERRANEAN FEVER: ASSESSING THE OVERALL CLINICAL IMPACT AND FORMULATING TREATMENT PLANS 2019-10-21T16:36:49+00:00 Donato Rigante Raffaele Manna, Prof. <p>Recurrent self-limited attacks of fever and short-lived inflammation in the serosal membranes, joints and skin are the leading features of familial Mediterranean fever (FMF), the most common autoinflammatory disorder in the world, transmitted as autosomal recessive trait caused by MEFV gene mutations. Their consequence is an abnormal function of pyrin, a natural repressor of inflammation, apoptosis and release of cytokines. FMF-related mutant pyrins are hypophosphorylated following RhoA&nbsp;GTPases’ impaired activity and show a propensity to relapsing uncontrolled systemic inflammation with inappropriate response to inflammatory stimuli and leukocyte spread to serosal membranes, joints or skin. Typical FMF phenotype 1 consists of brief episodes of inflammation and serositis, synovitis, and/or erysipelas-like eruption, whereas phenotype 2 is defined by reactive amyloid-associated (AA) amyloidosis, which is the most ominous complication of FMF, in otherwise asymptomatic individuals. Furthermore, FMF phenotype 3 is referred to the presence of two MEFV mutations with neither clinical signs of FMF, nor AA amyloidosis. The influence of epigenetic and/or environmental factors can contribute to the variable penetrance and phenotypic heterogeneity of FMF.&nbsp;Colchicine, a tricyclic alkaloid with anti-microtubule and anti-inflammatory properties, is the bedrock of FMF management: daily administration of colchicine prevents the recurrence of FMF attacks and the development of secondary AA amyloidosis. Many recent studies have also shown that anti-interleukin-1 treatment is actually the best therapeutic option for FMF patients nonresponsive or intolerant to colchicine. This review aims to catch readers’ attention on the clinical diversity of phenotypes, differential diagnosis, and management of patients with FMF.</p> 2019-04-25T17:44:25+00:00 ##submission.copyrightStatement## Guest Editor: Raffaella Origa THYROID DISORDERS IN HOMOZYGOUS β-THALASSEMIA: CURRENT KNOWLEDGE, EMERGING ISSUES AND OPEN PROBLEMS 2019-10-21T16:36:48+00:00 Vincenzo De Sanctis <p><strong>Abstract. </strong>Changes in thyroid function and thyroid function tests occur in patients with β-thalassemia major (TM). The frequency of hypothyroidism in TM patients ranges from 4% to 29 % in different reports. The wide variation has been attributed to several factors such as patients' genotype, age, ethnic variations, treatment protocols of transfusions and chelation, and varying compliance to treatment. Hypothyroidism is the result of primary gland failure or insufficient thy­roid gland stimulation by the hypothalamus or pituitary gland. The main laboratory parameters of thyroid function are the assessments of serum thyroid-stimulating hor­mone (TSH) and serum free thyroxine (FT4). It is of primary importance to interpret these measure­ments within the context of the laboratory-specific normative range for each test. An ele­vated serum TSH level with a normal range of serum FT4 level is consistent with subclinical hypothyroidism. A low serum FT4 level with a low, or inappropriately normal, serum TSH level is consistent with secondary hypothyroidism. Doctors caring for TM patients most commonly encounter subjects with subclinical primary hypothy­roidism in the second decade of life. Several aspects remain to be elucidated as the frequency of thyroid cancer and the possible existence of a relationship between thyroid dysfunction on one hand, cardiovascular diseases, components of metabolic syndrome (insulin resistance) and hypercoagulable state on the other hand. Further studies are needed to explain these emerging issues. Following a brief description of thyroid hormone regulation, production and actions, this article is conceptually divided into two parts; the first reports the spectrum of thyroid disease occurring in patients with TM, and the second part focuses on the emerging issues and the open problems in TM patients with thyroid disorders.</p> 2019-04-25T21:41:38+00:00 ##submission.copyrightStatement## Guest Editor: Raffaella Origa IRON TOXICITY AND HEMOPOIETIC CELL TRANSPLANTATION: TIME TO CHANGE THE PARADIGM. 2019-10-21T16:36:48+00:00 Federica Pilo <p>The issue of iron overload in hemopoietic cell transplantation has been first discussed in the field of transplantation for thalassemia. Thalassemia major is characterized by ineffective erythropoiesis and hemolysis leading to anemia in the majority of patients. Patients require regular blood transfusion therefore they develop iron overload causing organ damage and hematopoietic cell transplantation (HCT) is a consolidated reliably curative option. <br>In this category of patients an important issue for transplant outcome is the iron burden before transplant and in the long-life post-transplant. Nevertheless, today the concept of the impact of iron overload / toxicity on the outcome of HCT) has been extended to other diseases characterized by periods of variable duration of transfusion dependence <br>Recent preclinical data has shown how increased production of reactive oxygen species (ROS) resulting under iron overload condition, could impair the stem cells clonality capacity, proliferation and maturation. Also, microenvironment cells could be affected through this mechanism. For this reason, iron overload is becoming an important issue also in the engraftment period post-transplant<br>The aim of this review is to update consolidated knowledge about the role of iron overload/iron toxicity in the HCT setting in non-malignant and in malignant diseases introducing the concept of exposition of free toxic iron forms and related cellular damage in the different stage of transplant.</p> 2019-04-25T21:52:11+00:00 ##submission.copyrightStatement## SICKLE CELL DISEASE AND PREGNANCY 2019-10-21T16:36:46+00:00 Dipty Jain Pooja Lodha Roshan Colah Prachi Atmapoojya Prachi Atmapoojya <p><strong><span style="text-decoration: underline;">Abstract</span></strong></p> <p>&nbsp;</p> <p>Sickle Cell Disease (SCD) is a group of inherited single-gene autosomal recessive disorders caused by the ‘sickle’ gene, which affects haemoglobin structure. Sickle cell anemia is the most common hemoglobinopathy worldwide. The burden of sickle cell disease in pregnancy has been exponentially increasing with more number of women reaching the reproductive age, and having successful pregnancies. It has been proven beyond doubt that SCD in pregnancy poses the pregnant woman and fetus to significantly higher risks than a lady without SCD. SCD is associated with both maternal and fetal complications and is associated with an increased incidence of perinatal mortality, premature labour,&nbsp; fetal growth restriction and acute painful crises during pregnancy.&nbsp; Some studies also describe an increase in spontaneous miscarriage, antenatal hospitalisation, maternal mortality, delivery by caesarean section, infection, thromboembolic events and antepartum haemorrhage.</p> <p>&nbsp;</p> <p>This review aims to discuss the risks of SCD in pregnancy - to the mother and fetus .

This systematic review aims to determine the cost-effectiveness of four chelation regimens and provide evidence for the rational use of chelation regimens for β-thalassemia major therapy in clinic.<br>Methods:<br>A systematic literature search in PubMed, EMBASE (Ovid), CENTRAL (Cochrane library), HTAD (Cochrane library), NHS EED (Cochrane library), CBM, CNKI, VIP, and Wanfang was conducted in April 2018. In addition, a manual search was performed. Two researchers, working independently, selected the papers, extracted the data and assessed the methodological quality of the included papers. Each included paper was evaluated using a checklist developed by Drummond et al. <br>Results:<br>The initial number of records was 968, and eight papers met the final eligibility criteria. All the included eight papers were cost-utility analyses. And the methodological quality of these papers was good. Nineteen studies were included in eight papers. Nine studies of DFX versus DFO had contradictory results. Out of the nineteen studies, three studies of DFX versus DFP established that using DFP was cost-effective. Three studies of DFP versus DFO established that using DFP was cost-effective. One study of DFP and DFO combination therapy versus DFO found that using DFO was cost-effective. One study of DFP and DFO combination therapy versus DFP found that using DFP was cost-effective. And there were two studies of DFP and DFO combination therapy versus DFX, but we cannot be sure which one of two chelation regimens was cost-effective. <br>Conclusion:<br>In brief, DFP is the best choice, followed by DFO or DFX, when an iron chelator is to be used alone for β-thalassemia major therapy. All studies that compared DFO and DFP combination therapy with DFO (or DFP or DFX) monotherapy established that the combination therapy with DFO and DFP was not cost-effective. However, due to the low number of related studies, more extensive, high-quality research is required for further analysis and confirmation of our findings. Moreover, the cost effectiveness is not an absolute issue when in different countries(regions) the results are opposite for other countries(regions). The specific region had a substantial influence on the economy of drugs.</p> <p>Key words: β-thalassemia major, Deferoxamine, Deferiprone, Deferasirox, cost-effectiveness, systematic review</p> 2019-06-24T21:28:52+00:00 ##submission.copyrightStatement## SICKLE CELL DISEASE AND INFECTIONS IN HIGH- AND LOW-INCOME COUNTRIES 2019-10-21T16:36:44+00:00 Giovanna Cannas <p>Infections, especially pneumococcal septicemia, meningitis, and <em>Salmonella</em> osteomyelitis, are a major cause of morbidity and mortality in patients with sickle cell disease (SCD). SCD increased susceptibility to infection, while infection leads to SCD-specific pathophysiological changes. The risk of infectious complications is highest in children with a palpable spleen before 6 months of age. Functional splenectomy, the results of repeated splenic infarctions, appears to be an important host-defense defect. Infection is the leading cause of death, particularly in less developed countries. Defective host-defense mechanisms enhance the risk of pneumococcal complications. Susceptibility to <em>Salmonella</em> infections can be explained at least in part by a similar mechanism. In high-income countries, the efficacy of the pneumococcal vaccine has been demonstrated in this disease. A decreased in infection incidence has been noted in SCD patients treated prophylactically with daily oral penicillin. Studies in low-income countries suggest the involvement of a different spectrum of etiological agents.</p> 2019-06-25T14:08:27+00:00 ##submission.copyrightStatement## THERAPEUTIC TARGETING OF NOTCH SIGNALING PATHWAY IN HEMATOLOGICAL MALIGNANCIES 2019-10-21T16:36:43+00:00 Giovanni Roti Claudia Sorrentino Antonio Cuneo <p>The Notch pathway plays a key role in several processes including stem-cell self-renewal, proliferation, and cell differentiation. Several studies identified recurrent mutations in hematological malignancies making Notch one of the most desirable target in leukemia and lymphoma. The Notch signaling mediates resistance to therapy and controls cancer stem cells supporting the development of on-target therapeutic strategies to improve patients’ outcome.

Aging is associated not only with the comorbidities stemming from their inherited bleeding disorder (arthropathy, chronic viral infections such as hepatitis and AIDS) but also with the multiple chronic ailments associated with aging (cancer, cardiovascular disease, COPD).&nbsp; Multimorbidity is inevitably associated with polypharmacy, i.e., the chronic daily intake of at least five drugs, and with the related risk of severe adverse events associated with the use of inappropriate drugs and drug-drug interactions. Information on the pattern of drug prescription and usage by PWH is relatively scanty, but on the whole, the available data indicate that the rate of polypharmacy, as well as the risk of drug-drug interaction, is relatively low in PWH and better than that in their age peers without hemophilia followed by general practitioners. It is believed that this advantage results from the collaborative coordination on drug prescribing exerted, through their integration with practitioners and organ specialists, by specialized hemophilia treatment centers in the frame of comprehensive care programs. However, the available cross-sectional data were mainly obtained in relatively young PWH, so that there is a need to obtain more accurate data from the ongoing prospective studies that are being carried out in more and more progressively aging PWH.</p> <p>&nbsp;</p> <p>&nbsp;Keywords: Hemophilia; Aging; Comorbidity; Drugs Interaction.</p> <p>&nbsp;</p> 2019-08-29T00:00:00+00:00 ##submission.copyrightStatement## CORD BLOOD PLATELET LYSATE: IN VITRO EVALUATION TO SUPPORT THE USE IN REGENERATIVE MEDICINE. 2019-10-21T16:36:52+00:00 Luciana Teofili <p>Platelet-rich plasma (PRP) is an inexpensive and safe substitute of recombinant growth factors in Vitro and <em>in vivo</em>. Due to its putative effect on tissue repair, the use of autologous PRP has become largely popular. Recently, a jellified PRP derivative obtained from umbilical cord blood (CB) has been utilized <em>in vivo&nbsp;</em>to treat mucosal and cutaneous lesions. Nevertheless, whether PRP derived from CB and adult blood display different potency in promoting cell growth in Vitro has been rarely investigated. In this study, we compared cytokine profile and mesenchymal cell growth supporting the ability of platelet lysate obtained from adult and cord blood. Our <em>in vitro&nbsp;</em>results strongly back the utilization of CB platelet lysate <em>in vivo</em>, as an efficacious, safe and inexpensive alternative to promote damaged tissue healing when the autologous PRP is contraindicated. Moreover, the policy of manufacturing CB platelet lysate can limit the current disposal of many collected CB units not suitable for transplant due to their low nucleated cell count.</p> <p>&nbsp;</p> <p>&nbsp;</p> 2019-02-25T17:46:49+00:00 ##submission.copyrightStatement## INTERNATIONAL MULTICENTER EXPERIENCE IN THE TREATMENT OF INVASIVE ASPERGILLOSIS IN IMMUNOCOMPROMISED CANCER PATIENTS 2019-10-21T16:36:53+00:00 R.

In this study, we compared the efficacy of voriconazole containing regimen vs non-voriconazole containing regimen in patients with IA.</p> <p><strong>METHODS: </strong>In this retrospective study, we reviewed the medical records of all immunocompromised cancer patients diagnosed with proven or probable IA between February 2012 and March 2018. This trial included 26 patients from the American University of Beirut,&nbsp; Lebanon, 20 patients from&nbsp; Hospital das Clinicas da Faculdade de Medicina, Universidade de&nbsp; São Paulo, Brazil, and 10 patients from St. Luke's International Hospital Tokyo, Japan.</p> <p><strong>RESULTS:&nbsp; </strong>A total of 56 patients were analyzed. They were divided into 2 groups voriconazole containing regimen and non-voriconazole containing regimen (90% Amphotericin B&nbsp; based regimen) . Both groups had similar characteristic, age, gender, and immunocompromised status. The majority of patients had underlying leukemia 53%, lymphoma 18%, myeloma 15% and solid tumor 13%. Antifungal primary therapy with voriconazole-containing regimen was associated with better response to treatment (P = 0.003). Survival analysis showed that primary therapy with a voriconazole containing regimen was significantly associated with improved survival (p =0.006). By multivariate logistic regression analysis, mechanical ventilation was predictor of worse outcome (poor response to therapy and increased mortality at 6 weeks), whereas primary treatment with voriconazole containing regimen was associated with improved outcome (OR=0.14; 95% CI 0.03-0.64, P=0.01).</p> <p><strong>CONCLUSIONS: </strong>Based on international experience in immunocompromised cancer patients with IA, primary therapy with voriconazole-containing regimen is associated with improved response and survival compared with non-voriconazole amphotericin B based regimen.</p> 2019-01-01T00:00:00+00:00 ##submission.copyrightStatement## DETECTION OF CALR MUTATIONS USING HIGH RESOLUTION MELTING CURVE ANALYSIS (HRM-A); APPLICATION ON A LARGE COHORT OF GREEK ET AND MF PATIENTS 2019-10-21T16:36:54+00:00 Andreas Giannopoulos Niki Rougkala Theodoros Loupis Marina Mantzourani Nora-Athina Viniou Eleni Variami Theodoros Vassilakopoulos George Dryllis Ioannis Kotsianidis Theodora Gougopoulou Marianna Politou Konstantinos Konstantopoulos George Vassilopoulos <p><strong><em>Background and Objectives</em></strong></p> <p>Somatic mutations in the calreticulin gene (<em>CALR</em>) are detected in approximately 70% of patients with essential thrombocythemia (ET) and primary or secondary myelofibosis (MF), lacking the&nbsp;<em>JAK2</em>and&nbsp;<em>MPL</em>mutations. To determine the prevalence of&nbsp;<em>CALR</em>frameshift&nbsp;mutations in a population of MPN patients of Greek origin, we developed a rapid low-budget PCR-based assay and screened samples from 5 tertiary Haematology units. This is a first of its kind report of the Greek patient population that also disclosed novel&nbsp;<em>CALR</em>mutants.</p> <p>&nbsp;</p> <p><strong><em>Methods</em></strong></p> <p>MPN patient samples were collected from different clinical units and screened for&nbsp;<em>JAK2</em>and&nbsp;<em>MPL</em>mutations after informed consent was obtained. Negative samples were analyzed for the presence of&nbsp;<em>CALR</em>mutations. To this end, we developed a modified&nbsp;post Real Time PCR High Resolution Melting Curve analysis (HRM-A) protocol.

Al-Madhani Anil Pathare Salam Alkindi <p><strong>Background</strong>: Newborn cord blood screening identifies infants with underlying haemoglobinopathies before they develop the characteristic symptoms or sequelae. </p><p><strong>Aims</strong>: This study was performed to validate the interpretation high-performance chromatography (HPLC) along with complete blood count (CBC) results as a tool for universal neonatal screening of hemoglobin disorders in Oman. </p><p><strong>Methods</strong>: HPLC and CBC data on subjects who participated in the National Neonatal screening program at birth were obtained from archival records. The results recorded at birth were compared with a second study performed on the same subjects, after approval from the local medical research and ethics committee.</p><p><strong>Results</strong>: Only 290 subjects from amongst the original cohort of 3740 newborns could be recalled between April 2010 to March 2011, to repeat HPLC and CBC, as well as perform confirmatory DNA studies, wherever necessary. All these subjects had been documented to show an initial abnormal result. 31 cases who had no HbA at birth on HPLC were confirmed as either homozygous β-thalassaemia major (n=5 subjects) or homozygous sickle cell anemia (n=26 subjects) by appropriate DNA analysis. Additionally, amongst 151 subjects, 72 subjects were studied in the initial study by Hb Bart’s quantitation using <strong>a</strong>alpha thalassaemia short program at birth. In this cohort, 42 subjects with Hb Bart’s &gt;1% at birth could be confirmed as having either deletional or non-deletional thalassaemia by GAP PCR studies. No case of HbH was detected in this cohort. Further, carrier status for structural hemoglobin variants (HbS, HbC, HbD, HbE) (n=67) and beta thalassaemia allele with low HbA at birth (n=29 out of 41) were confirmed by relevant molecular studies.</p><p><strong>Conclusions</strong>: The study validated the earlier observation by 100% concordance with results of CBC and HPLC.

This study evaluated the clinical characteristics of RVI and established strategies for the PCR test in children and adolescents with hematological malignancies.<br>Methods: This study included children and adolescents with underlying hematological malignancies and respiratory symptoms, in whom a multiplex PCR test was performed. Patients in whom RVI was identified and not identified were categorized into Groups I and II, respectively. Group I was sub-divided into patients with upper and lower respiratory infections. The medical records of the enrolled patients were retrospectively reviewed.<br>Results: A total of 93 respiratory illnesses were included. Group I included 46 (49.5%) cases of RVI, including 31 (67.4%) upper and 15 (32.6%) lower respiratory infections. Rhinovirus (37.0%) was the most common viral pathogen. Significantly more patients in Group I had community-acquired respiratory illnesses (p=0.003) and complained of rhinorrhea (p&lt;0.001) and sputum (p=0.008) than those in Group II. In Group I, significantly more patients with lower respiratory infections had uncontrolled underlying malignancies (p=0.038) and received re-induction or palliative chemotherapy (p=0.006) than those with upper respiratory infections.<br>Conclusions: A multiplex PCR test should be considered for RVI diagnosis in immunocompromised children and adolescents with respiratory symptoms, especially in those with rhinorrhea or sputum prominent over a cough.

Vitamin D is important for bone mineralization. Vitamin D receptors (VDR) genetic variants may be related to vitamin D status and BMD.</p><p><strong>Objectives</strong><strong>:</strong>  To evaluate the effect of VDR genetic variants on vitamin D levels and BMD in βTM Egyptian patients supplemented with vitamin D.</p><p><strong>Methods</strong>: This study was conducted on forty children with βTM and forty unrelated healthy sex and age-matched controls. Serum calcium, phosphorus, ALP, ferritin and vitamin D were measured. VDR genetic variants (<em>BsmI</em>, <em>TaqI</em>, and <em>FokI</em>) were genotyped by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). BMD was measured by dual-energy X-ray densitometry (DEXA) of the lumbar spine.</p><p><strong>Results:</strong> In βTM patients, 22.5% had deficient, 50% had insufficient and only 27.5% had sufficient levels of vitamin D. BMD Z score was significantly lower in βTM patients compared to controls (p&lt;0.001). Osteopenia and osteoporosis of lumbar spines were observed in 70% and 22.5% of βTM patients respectively. <em>BsmI </em>bb and <em>FokI</em> Ff and ff genotypic variants were significantly associated with lower vitamin D and BMD Z score. No association was observed with <em>TaqI</em> genotypic variants.</p><p><strong>Conclusions:</strong> We reported a high prevalence of low BMD in βTM despite vitamin D supplementation. The <em>BsmI</em> bb, <em>FokI</em> Ff and ff genotypic variants of VDR can be considered as risk factors for the occurrence of osteoporosis in these children. Vitamin D doses should be adjusted individually according to the genetic makeup of each patient.<strong></strong></p> 2019-01-01T00:00:00+00:00 ##submission.copyrightStatement## SOLUBLE ST2 AND CD163 AS POTENTIALBIOMARKERS TO DIFFERENTIATE PRIMARY HEMOPHAGOCYTIC LYMPHOHISTIOCYTOSIS FROM MACROPHAGE ACTIVATION SYNDROME 2019-10-21T16:36:55+00:00 Zhuo Gao Yini Wang Jingshi Wang Jia Zhang Zhao Wang <p>Abstract</p> <p><em>Background and Objective:</em> The differentiation of primary haemophagocytic lymphohistiocytosis (pHLH) and macrophage activation syndrome (MAS)&nbsp;poses&nbsp;a challenge&nbsp;to hematologists. The aim of this study was (1) to compare the levels of soluble ST2 (sST2), sCD163, IL-10, IFN-γ, TNF-α and IL-18 in patients with pHLH and MAS and (2) to investigate whether they can help differentiate the two diseases.</p> <p><em>Methods:</em> A total of 54 participants were recruited in this study, including 12 pHLH patients, 22 MAS patients and 20 healthy subjects. We measured the levels of sST2 and sCD163 in serum by ELISA. The serum levels of IL-10, IFN-γ, TNF-α and IL-18 were detected using a Luminex 200 instrument.</p> <p><em>Results:</em> The serum levels of sST2 and sCD163 in MAS patients were markedly higher than that in pHLH patients (363.13 ± 307.24 ng/ml vs 80.75 ± 87.04 ng/ml, <em>P</em> = 0.004; 3532.72 ± 2479.68 ng/ml vs 1731.96 ± 1262.07 ng/ml, <em>P</em> = 0.046). There was no significant difference in the expression of IFN-γ (306.89 ± 281.60 pg/ml vs 562.43 ± 399.86 pg/ml), IL-10 (20.40 ± 30.49 pg/ml vs 8.3 ± 13.14 pg/ml<strong>)</strong>, IL-18 (463.33 ± 597.04 pg/ml vs 1247.82 ± 1318.58 pg/ml) and TNF-α (61.48 ± 84.69 pg/ml vs 106.10 ±77.21 pg/ml) between pHLH and MAS.</p> <p><em>Conclusion:</em> Patients with pHLH and MAS show some differences in cytokine profiles. The elevated levels of IFN-γ, IL-10, IL-18 and TNF-α can contribute to the diagnosis of HLH, but may not discriminate pHLH from MAS. Levels of sST2 and sCD163 may serve as markers to distinguish pHLH from MAS.</p> 2019-01-01T00:00:00+00:00 ##submission.copyrightStatement## INCREASE IN CANDIDA PARAPSILOSIS CANDIDEMIA IN CANCER PATIENTS 2019-10-21T16:36:55+00:00 Mingyue Sun Chunguang Chen weiqiang xiao yanmin Chang cailin Liu Qingxia Xu <p><strong>Background:</strong> This study aimed to identify the risk factors of candidemia and asses possible clinically significant differences between <em>Candida parapsilosis</em> and other candida species among cancer patients.</p> <p><strong>Methods:</strong> A retrospective study was conducted in a Chinese tertiary cancer center over a 6-year period. A total of 323 cancer patients were enrolled and analyzed from 2012 to 2018. Data about demographic characteristics, underlying diseases, and risk factors of candidemia were collected. Univariate and multivariate logistic regression models were used to identify the risk factors associated with the development of candidemia.</p> <p><strong>Results:</strong> Among the isolates, the species most frequently isolated was <em>C. parapsilosis</em> (37.15%, 120/323), and <em>C. albicans </em>only accounted for 34.37%. Based on statistical analysis, when candidemia patients who had <em>C. parapsilosis</em> were compared with other <em>Candida</em> spp., the following factors were found to be significantly associated with <em>C. parapsilosis</em> fungemia: parenteral nutrition (p &lt; 0.001), neutropenia (p &lt; 0.001), receipt of chemotherapy (p = 0.002), and previous antifungal use (p &lt; 0.001).

Clinical variables including age of diagnosis of SCA, frequency of vaso-occlusive crisis and transfusion therapy, as well as laboratory data including haematological profile, renal function test were obtained from routine blood result. The glomerular filtration rate was estimated (eGFR) using the ‘modification of diet in renal disease’ (MDRD) formula.<sup>.</sup></p><p><strong>Results</strong>: Two hundred and eighty-four HbSS patients were recruited. The prevalence of CKD amongst them was 38.9%.  Further stratification of the patients based on eGFR showed that sixty-nine (26.8%) had hyperfiltration; 35 (13.6%) stage 1 CKD; 53 (20.6%) stage 2 CKD; 61 (23.7%) stage 3 CKD; 30 (11.7%) stage 4 CKD and 9 (3.5%) had end stage renal disease. There was significant association between eGFR and clinical parameters such as age (r -0.353, p=0.000), SBP (r -0.148, p= 0.021), DBP (r -0.213, p=0.001) and total number of blood received (r -0.276, p=0.000); and laboratory parameters such as  PCV (r 0.371, p=0.000); urea ( r 0.527, p=000 ); creatinine (r 0.625, p=0.000) and uric acid  ( r -0.419, p=0.000).</p><p><strong>Conclusion</strong></p><p>The present study has revealed a high prevalence of CKD amongst patients with SCA in this region.

The choice of the anthracycline employed has been widely studied in multiple clinical trials showing similar complete remission rates.</h4> <p><strong>MATERIALS AND METHODS:</strong> Using an <em>ex vivo</em> test we have analyzed if a subset of AML patients may respond differently to cytarabine combined with idarubicin, daunorubicin or mitoxantrone. &nbsp;Bone marrow (BM) samples of 198 AML patients were incubated for 48 hours in 96 well plates, each well containing different drugs or drug combinations at different concentrations. <em>Ex vivo</em> drug sensitivity analysis was made using the PharmaFlow platform maintaining the BM microenvironment. Drug response was evaluated as depletion of AML blast cells in each well after incubation. Annexin V-FITC was used to quantify the ability of the drugs to induce apoptosis, and pharmacological responses were calculated using pharmacokinetic population models.</p> <p><strong>RESULTS: </strong>Similar dose-respond graphs were generated for the three anthracyclines, with a slight decrease in EC<sub>50</sub> with idarubicin (p=1.462E-06), whereas the interpatient variability of either drug was large. To identify those cases of selective sensitivity to anthracyclines, potency was compared, in terms of area under the curve.

The objective of this study is to analyze the causes of death and the effect of sex and age on survival of Brazilian patients with SCA. Data of patients with SCA who were seen and followed at HEMORIO for 15 years were retrospectively collected and analyzed. Statistical modeling was performed using survival analysis in the presence of competing risks estimating the covariate effects on a sub distribution hazard function. Eight models were implemented, one for each cause of death. The cause‐specific cumulative incidence function was also estimated. Males were most vulnerable for death from chronic organ damage (p = 0.0005) while females were most vulnerable for infection (p=0.03). Age was significantly associated (p ≤ 0.05) with death due to acute chest syndrome (ACS), infection, and death during crisis. The lower survival was related to death from infection, followed by death due to ACS. The independent variables age and sex were significantly associated with ACS, infection, chronic organ damage and death during crisis. These data could help Brazilian authorities strengthen public policies to protect this vulnerable population.</p> 2019-02-26T21:28:30+00:00 ##submission.copyrightStatement## COMPARISON OF THE POWER OF PROCALCITONIN AND C-REACTIVE PROTEIN TO DISCRIMINATE BETWEEN DIFFERENT AETIOLOGIES OF FEVER IN PROLONGED PROFOUND NEUTROPENIA: A SINGLE-CENTRE PROSPECTIVE OBSERVATIONAL STUDY. 2019-10-21T16:36:49+00:00 Anke Verlinden Veronique De Vroey Herman Goossens Ella Roelant Ann Van de Velde Zwi Berneman Wilfried Schroyens Alain Gadisseur <p>Management of fever in prolonged profound neutropenia remains challenging with many possible infectious and non-infectious causes. We investigated whether procalcitonin (PCT) is superior to C-reactive protein (CRP) in discriminating between different etiologies of fever in this setting.</p> <p>CRP and PCT were tested daily during 93 neutropenic episodes in 66 patients. During this study period 121 febrile episodes occurred and were classified into four categories based on clinical and microbiological findings: microbiologically documented infection (MDI); clinically documented infection (CDI); proven or probable invasive fungal disease (IFD); fever of unknown origin (FUO). Values of PCT and CRP at fever onset as well as 2 days later were considered for analysis of their performance in distinguishing etiologies of fever.</p> <p>At fever onset no significant difference in PCT values was observed between different etiologies of fever, whereas median CRP values were significantly higher in case of IFD (median 98.8 mg/L vs 28.8 mg/L, p=0.027). Both PCT and CRP reached their peak at a median of 2 days after fever onset. Median PCT values on day 2 showed no significant difference between etiologies of fever. Median CRP values on day 2 were significantly higher in IFD (median 172 mg/L versus 78.4 mg/L, p=0.002). In MDI median CRP values rose &gt; 100 mg/L, whereas they did not in CDI or FUO.</p> <p>PCT has no added value over CRP for clinical management of fever in prolonged profound neutropenia. When performing reassessment 2 days after fever onset, CRP has better discriminatory power between etiologies of fever.</p> 2019-02-26T21:30:21+00:00 ##submission.copyrightStatement## FINAL HEIGHT AND ENDORINE COMPLICATIONS IN PATIENTS WITH β-THALASSSEMIA INTERMEDIA: OUR EXPERIENCE IN NON-TRANSFUSED VERSUS INFREQUENTLY TRANSFUSED PATIENTS AND CORRELATIONS WITH LIVER IRON CONTENT 2019-10-21T16:36:48+00:00 Vincenzo De Sanctis Mohamed Yassin <p><strong>Abstract. <em>Backgrond: </em></strong><strong>β</strong><strong>-</strong>thalassemia intermedia (TI) spans a wide spectrum of severity and carries higher morbidity than previously recognized, including extramedullary hematopoeisis, leg ulcers, gallstones, thrombosis, secondary heart failure, pulmonary hypertension, skeletal deformity, growth retardation and endocrine abnormalities, such as diabetes mellitus, hypothyroidism, osteoporosis, and hypogonadism.</p> <p><strong><em>Objectives:</em></strong> To evaluate the final height and the endocrine complications encountered in young adult patients with TI followed at Hematology Section, Doha (Qatar) in relation to liver iron content in non-transfused versus infrequently transfused TI patients.</p> <p><strong><em>Patients and Methods: </em></strong>This retrospective cohort study was performed on 28 young adults with TI who were randomly selected from the Hematology Clinic of the Hematology Section, National Centre for Cancer Care and Research, Hamad Medical Corporation of Doha (Qatar).</p> <p>Eligibility criteria for this retrospective analysis included TI patients diagnosed by complete blood count, hemoglobin electrophoresis and young adult age ( ≥ 18 years).</p> <p>Group 1 included 9 patients who did not receive any blood transfusion and Group 2 included 19 patients who infrequently received blood transfusion.</p> <p>Data recorded from charts included demographic characteristics (gender, date of birth, ethnicity), disease and treatment characteristics (e.g., transfusion frequency, history of chelation therapy, and splenectomy), auxological and pubertal data [growth percentiles and pubertal stages, and body mass index (BMI)], laboratory data and target organ complications (including endocrinopathies and liver disease). Iron overload was assessed by direct (liver iron content; LIC) and indirect methods (SF), and bone mass index (BMA) by dual-energy X-ray absorptiometry (DXA).</p> <p><strong><em>Results:</em></strong> Short stature [Final Height (Ht) SDS &lt; -2] occurred in 25% of patients with no difference between the two groups of patients. Insulin growth factor 1 (IGF-1) SDS was low in 35.7 % of patients with no statistical difference among the two groups. Impaired fasting blood glucose occurred in 17.8% of patients, diabetes mellitus in 25% and hypogonadotropic hypogonadism in 10.7% of them. Morning cortisol was low in one patient. No thyroid or hypoparathyroid abnormalities were detected in any patient. Liver iron content (LIC) &gt; 15 mg/g dry weight and SF &gt; 2,000 ng/mL were detected in 75% of the patients.

Although, long term growth delay and abnormal weight gain appear to be risk factors following an acute attack of both bacterial and aseptic meningitis in children, especially during the fast phase of infantile growth, the long-term effects of acute meningitis occurring during the neonatal and early infantile periods on linear growth (length, weight and head growth) have not fully reported. </strong></p> <p><strong>Aim of the study:</strong><strong> The objective of this study is to describe the clinical presentation of neonates and young infants with acute meningitis with</strong><strong> different etiologies</strong><strong> and </strong><strong>to determine the clinical impact of </strong><strong>the effect of acute meningitis </strong><strong>on growth parameters. </strong></p> <p><strong>Material and methods: </strong><strong>We analyzed the clinical data and the growth parameters of 50 newborns and young infants (age: 1.6 ± 0.9 month) admitted to our hospital (Al Wakhra Hospital, Department of Pediatrics, Doha ,Qatar), between 1-1-2016 to 1-1-2017, with acute meningitis. Anthropometric measurements included weight, length, and head circumference.

The present study was an investigation into ESBL molecular characteristics among clinical isolates of <em>Klebsiella pneumoniae</em> and <em>Escherichia coli</em> resulting in UTIs and their pattern of antimicrobial resistance in order to come up with helpful information on the epidemiology of these infections and risk factors accompanied with them. In order to conduct the study, 20 <em>K. pneumoniae</em> and 48 <em>E. coli</em> were isolated and retrieved from thalassemia center in Erbil, Iraq during July 2016 and September 2016. The collected strains were analyzed and the profile of their antimicrobial susceptibility was specified. In order to spot β-lactamase genes (i.e. <em>bla</em>TEM, <em>bla</em>SHV, and <em>bla</em>CTX-M), polymerase chain reaction was conducted. The results obtained from multiplex PCR assay showed that out of the collected strains of ESBL-producing <em>E. coli</em>, 37 had 81% <em>bla</em>TEM, 16.2% <em>bla</em>SHV, and 32.4% <em>bla</em>CTX-M genes. Similarly, 64.7% <em>bla</em>TEM, 35.2% <em>bla</em>SHV, and 41.1% <em>bla</em>CTX-M genes existed in the isolates of<em> K. pneumoniae</em>. It was found that antibiotic resistance pattern of <em>E. coli</em> and <em>K. pneumoniae</em> isolates to 20 antibiotics varied widely. It was also concluded that the majority of the <em>K. pneumoniae </em>and <em>E. coli</em> isolates were multi-drug resistant (MDR). Moreover, 75% and 87.5% of respectively <em>K. pneumoniae</em> and <em>E. coli</em> isolates showed the MDR phenotypes. TEM prevalence was high among other types of ESBLs. Over all, the most active antimicrobial agents <em>in vitro</em> remained to be the carbapenems.</p> 2019-06-25T13:44:38+00:00 ##submission.copyrightStatement## DIRECT ORAL ANTICOAGULANTS IN PATIENTS AFFECTED BY MAJOR CONGENITAL THROMBOPHILIA 2019-10-21T16:36:43+00:00 alessandra serrao benedetta lucani davide mansour antonietta ferretti erminia baldacci cristina santoro robin foà antonio chistolini <p><strong>Introduction</strong>: Thrombophilia is a condition that predisposes to a higher incidence of venous thromboembolisms (VTE), some also in atypical sites.

We aimed to evaluate the utility of procalcitonin (PCT), presepsin (PS), C-reactive protein (CRP) and interleukin-8 (IL-8) as biomarkers of bacteraemia in adult FN patients with haematological malignancies.&nbsp;Thirty-six FN episodes experienced by 28 oncohematological patients were considered.&nbsp;11 out of 36 episodes were classified as bacteraemia. PCT was the best biomarker to predict bacteraemia with area under the curve (AUC) ROC of 0,9; while the most sensitive was IL-8 (90,9%) with AUC ROC of 0,88. All patients with PCT concentrations above 1,6 μg/l had bacteraemia. Patients with IL-8 concentrations &gt; 170 pg/ml or&nbsp;PS concentrations superior then 410 pg/ml had 40 times and 24 times higher risk for bacteraemia, respectively. PCT remains better than IL-8 and PS in predicting bacteraemia in adult hematological patients with FN.</p> 2019-08-29T14:34:49+00:00 ##submission.copyrightStatement## PREVALENCE AND FACTORS ASSOCIATED WITH HUMAN PARVOVIRUS B19 INFECTION IN SICKLE CELL PATIENTS HOSPITALIZED IN TANZANIA 2019-10-21T16:36:41+00:00 Florence Urio Humphrey George Furahini Tluway Thomas B Nyambo Bruno P Mmbando Julie Makani <h1>Background: The distribution of human parvovirus B19 (HPV B19) infection is ubiquitous and occurs worldwide. The virus has high tropism to red blood cells progenitor`s cells leading to temporary infection of bone marrow and transient arrest of erythropoiesis. People with frequent episodes of haemolytic anaemia including sickle cell disease (SCD) and thalassemia are at increased risk of infection. This study aimed at assessing prevalence and factors associated with HPV B19 infections among hospitalized SCD patients.</h1> <h1>Methodology: This is a cross-sectional hospital-based study among 329 SCD patients hospitalized at Muhimbili National Hospital (MNH). HPV B19 was detected using RT-PCR. Haematological and Chemistry tests were done using Sysmex XT2000i and Chemistry analyser respectively.</h1> <h1>Results: The prevalence of HPV B19 among hospitalized 329 SCD patients was 29%. The median age for hospitalized SCD patients with HPV B19 was 15 years (IQR; 7-22), no variation of prevalence with age. In multivariate logistic regression model, HPV B19 infection was associated with pain (OR=4.28, 95%CI: 1.20–15.19; p=0.025), low neutrophil counts (OR=0.57,95%CI: 0.35–0.92, p=0.022) and MCH (OR=0.92, 95%CI: 0.85–0.99; p=0.033). In univariate analysis, HIV infection was slightly higher in SCD patients infected with HPVB19 (exact p-value=0.083).</h1> <h1>Conclusion: The prevalence of HPV B19 among hospitalized SCD patients at MNH was high. SCD patients with HPV B19 were more likely to present with pain, low neutrophils levels and MCH. HIV infection might be associated with high risk of HPV infection in SCD patients, however this requires further investigation.</h1> 2019-08-29T14:37:59+00:00 ##submission.copyrightStatement## CMV MANAGEMENT WITH SPECIFIC IMMUNOGLOBULINS: A MULTICENTRIC RETROSPECTIVE ANALYSIS ON 92 ALLOTRANSPLANTED PATIENTS. 2019-10-21T16:36:41+00:00 Michele Malagola Raffaella Greco Stella Santarone Anna Paola Iori Luisa Quatrocchi Walter Barberi Bruzzese Antonella Salvatore Leotta Alessandra Carotti Antonio Pierini Simon Bernardi Enrico Morello Nicola Polverelli Alessandro Turra Federica Cattina Lisa Gandolfi Benedetta Rambaldi Francesca Lorentino Francesca Serio Annalisa Natale Giuseppe Milone Andrea Velardi Robin Foà Fabio Ciceri Domenico Russo Jacopo Peccatori <p align="justify" class="western" style="line-height: 150%; margin-bottom: 0cm;"><span style="color: rgb(0, 0, 128);"><span lang="zxx"><span style="color: rgb(0, 0, 0);"><span style="text-decoration: none;">CMV represent</span></span></span></span><span style="color: rgb(0, 0, 128);"><span lang="zxx"><span style="color: rgb(0, 0, 0);"><span lang="en-US"><span style="text-decoration: none;">s</span></span></span></span></span><span style="color: rgb(0, 0, 128);"><span lang="zxx"><span style="color: rgb(0, 0, 0);"><span style="text-decoration: none;"> one of the most serious life-threatening complications of allogeneic stem cell transplantaion (allo-SCT).

Background: Haemorrhagic cystitis (HC) is a severe complication occurring after haematopoietic stem cell transplantation (HSCT) in 13-40% of patients, caused by infectious and/or non-infectious factors that increases the in-hospital length of stay and the risk of mortality of transplanted recipients. Although different management interventions have been suggested in literature, available knowledge on interventions performed by Italian nurses in their daily practices has not been documented to date.<br>Aim of the study: The objective of this study is to describe HC preventive and treatment interventions in patients undergoing HSCT as performed by Italian nurses in their daily practice.<br>Material and methods: A multicentre survey was conducted in 2018 inviting all 110 Italian HSCT centres belonging to the Italian Group for Bone Marrow Transplantation (GITMO). Data collection was performed with an online questionnaire submitted to GITMO reference nurses working in each HSCT centre. Descriptive statistics were performed.<br>Results: A total of 38 Italian centres participated. The preventive intervention most applied in daily care was the mesna administration (n=37; 97.4%), followed by intravenous hyperhydration (n=33; 86.8%) and forced diuresis with furosemide (n=24; 63.1%). Preventive continuous bladder irrigation (CBI) was performed in 13 centres (34.2%). Transfusions of blood products (n=32; 84.2%), CBI (n=31; 81.6%) and intravenous hydration (n=28; 73.7%) were the most applied treatments, beyond the administration of analgesics (n=38; 100.0%) and antispasmodics (n=26; 68.4%).<br>Conclusion: There is no gold standard for the prevention and treatment of HC in patients undergoing HSCT, although interventions applied by nurses agree with the literature. There is a need for methodological studies of higher quality, multicentre and prospective, that should focus even on nurses and supportive measures.</p> <p>&nbsp;</p> 2019-08-29T00:00:00+00:00 ##submission.copyrightStatement## PREGNANCY LOSS IN WOMEN WITH HIV IS NOT ASSOCIATED WITH HIV MARKERS: DATA FROM A NATIONAL STUDY IN ITALY, 2001-2018 2019-10-21T16:36:43+00:00 Marco Floridia Giulia Masuelli Beatrice Tassis Enrica Tamburrini Valeria Savasi Matilde Sansone Arsenio Spinillo Giuseppina Liuzzi Anna Degli Antoni Serena Dalzero Laura Franceschetti Giuliana Simonazzi Gianpaolo Maso Daniela Francisci Carmela Pinnetti Marina Ravizza <p><strong>Background: </strong>There is limited information on pregnancy loss in women with HIV, and it is still debate whether HIV-related markers may play a role.</p> <p><strong>Objectives: </strong>To explore potential risk factors for pregnancy loss in women with HIV, with particular reference to modifiable risk factors and markers of HIV disease.</p> <p><strong>Methods: </strong>Multicenter observational study of HIV-positive pregnant women.

Due to ongoing elevated CMV viral load and drug-associated myelosuppression, which prevented ganciclovir therapy, treatment was replaced by foscarnet. Due to nephrotoxicity, foscarnet was switched to LMV. The patient developed skin GvHD and prednisolone was started. Subsequently, CMV viremia worsened despite LMV therapy. Genotyping revealed the mutation C325Y of the CMV UL56 terminase being associated with high-level resistance against LMV. Prolonged uncontrolled low-level viremia due to prednisolone treatment may have favored the selection of drug-resistant CMV. Despite the excellent toxicity profile of LMV, physicians should be aware of risk factors for the emergence of resistance.</p> 2019-01-01T00:00:00+00:00 ##submission.copyrightStatement## Bortezomib maintenance for the treatment of Monoclonal Gammopathy of Renal Significance 2019-10-21T16:36:53+00:00 Holly Lee Peter Duggan Ernesta Paola Neri Jason Tay Victor Jimenez Zepeda <p>Monoclonal gammopathy of renal significance (MGRS) defines renal disease resulting from monoclonal proteins that are secreted from clonal B cells, that does not meet criteria for lymphoma or multiple myeloma.

We have deployed purposive sampling to pick 40 crew members who frequently travel to malaria endemic areas as part of their duty. The questionnaire contained both close and open-ended questions, which was given to the participants via the receptionists at the medical centre of the airline.</p> <p><strong>Results</strong></p> <p>Most of the cabin crew members were aware about malaria and its causes, symptoms, prevention and effective treatment. Many of the participants have been taking necessary precautions to ensure that they are safe but not all possible measures.</p> <p><strong>Conclusions</strong></p> <p>The baseline data should be further confirmed to assist in giving the appropriate recommendations to help combat the issue of protecting cabin crews from the risks of Malaria.</p> 2019-08-29T14:45:05+00:00 ##submission.copyrightStatement##
