The only proven cure for Shwachman-Diamond syndrome (SDS) bone marrow failure is allogeneic hematopoietic stem cell transplantation (HSCT). However HSCT with donors other than HLA-identical siblings is associated with high mortality and unfavorable prognosis. This paper presents the first experience of HSCT treatment of SDS using an unaffected HLA-identical sibling produced through preimplantation genetic diagnosis (PGD). The patient was a 6-year-old blood transfusion-dependent SDS baby girl with secondary myelodysplastic syndrome, for whom no HLA-identical donor was available...

For patients with AML, the best alternative donor remains to be defined. We analyze outcomes of patients who underwent myeloablative umbilical cord blood or haploidentical hemopoietic stem cell transplantation (HSCT) in Spain. Fifty-one patients underwent single umbilical cord blood transplantation supported by a third party donor (Haplo-Cord) between 1999 and 2012, and 36 patients received an haploidentical HSCT with post-transplant cyclophosphamide (PTCY-haplo) between 2012 and 2014 in GETH centers. The Haplo-Cord cohort included a higher proportion of patients with high disease risk index and use of TBI in the conditioning regimen, and hematopoietic cell transplantation-age Comorbidity Age Index was higher in PTCY-haplo patients...

BACKGROUND: Autologous hematopoietic stem cell transplantation (HSCT) of gene-modified cells is an alternative to enzyme replacement therapy (ERT) and allogeneic HSCT that has shown clinical benefit for adenosine deaminase-deficient (ADA-deficient) SCID when combined with reduced intensity conditioning (RIC) and ERT cessation. Clinical safety and therapeutic efficacy were evaluated in a phase II study. METHODS: Ten subjects with confirmed ADA-deficient SCID and no available matched sibling or family donor were enrolled between 2009 and 2012 and received transplantation with autologous hematopoietic CD34+ cells that were modified with the human ADA cDNA (MND-ADA) γ-retroviral vector after conditioning with busulfan (90 mg/m2) and ERT cessation...

Low antigenic expression of ABO subgroup system on red blood cell (RBC) is cause of discrepancy between forward and reverse blood typing in the standard agglutination technique. Neutralization agglutination is employed for verification of the detection of ABH substances in saliva. However, the neutralization technique is complicated, time-consuming and requires expertise. To overcome these drawbacks, surface plasmon resonance (SPR) imaging was developed for ABH antigen detection on RBCs and in saliva. An antibody array was designed to classify the ABO subgroups by anti-A, anti-B, and anti-H antibodies; the array was immobilized on a carboxymethyl-dextran sensor-surface...

In Chad, hepatitis B virus (HBV) is thought to have a high prevalence and is consequently responsible for numerous acute and long-term complications. It is often detected during screening in potential blood donors. However, no general population-based study on the prevalence of hepatitis B has been performed. The aim of this study was to gain an impression of the HBV prevalence in rural areas in south-west Chad. A total of 1309 individuals (745 boys/men, 564 girls/women) with a median age of 15 years (age range, 6-81 years) were screened for the presence of the hepatitis B antigen (HBsAG)...

Umbilical cord blood is a traditional and convenient source of cells for hematopoietic stem cell transplantation. Thymic regulatory T cells (Tregs) are also present in cord blood, and there is growing interest in the use of autologous Tregs to provide a low-risk, fully human leukocyte antigen (HLA)-matched cell product for treating autoimmune diseases, such as type 1 diabetes. Here, we describe a good manufacturing practice (GMP)-compatible Treg expansion protocol using fluorescence-activated cell sorting, resulting in a mean 2,092-fold expansion of Tregs over a 16-day culture for a median yield of 1...

Pregnancy-associated plasma protein-A (PAPPA), also known as pappalysin, is a member of the insulin-like growth factor (IGF) family. PAPPA acts as a protease, cleaving IGF inhibitors, i.e., IGF binding proteins (IGFBPs), thereby setting free IGFs. The insulin/IGF-axis is involved in cancer in general and in Ewing sarcoma (ES) in particular. ES is a highly malignant bone tumor characterized by early metastatic spread. PAPPA is associated with various cancers. It is overexpressed and required for proliferation in ES...

CD39 and CD73 are surface-expressed ectonucleotidases that hydrolyze ATP in a highly regulated, serial manner into ADP, AMP and adenosine. The end product, adenosine, has both tumor-promoting and immunosuppressive effects. The aim of this study was to determine CD73 expression on immune cells in pleural effusion (PE) in order to have a better understanding of the immune environment in mesothelioma. PE- or blood-derived CD14(+) cells of mesothelioma patients and healthy donors were analyzed by flow cytometry for the expression of CD39 and CD73...

EDITORIAL
Sean Cahill, Timothy Wang
In recent years, countries around the world have revised their blood donation policies regarding gay and bisexual men, and other men who have sex with men (MSM). The United States lifted the lifetime ban on MSM from donating blood in 2015, replacing it with a 1 year deferral policy allowing MSM to donate if they abstain from sex for 12 months. Other countries followed suit, while Italy and Spain have implemented deferral policies based on individual risk assessments regardless of sexual orientation. If Israel were to adopt a one year deferral policy for MSM, as recommended by Drs...

A longitudinal, prospective, observational, single-center, cohort study on healthy donors (HDs) was designed to identify predictors of CD34+ cells on day 5 with emphasis on the predictive value of the basal CD34+ cell count. As potential predictors of mobilization, age, sex, body weight, height, blood volume as well as white blood cell count, peripheral blood (PB) mononuclear cells, platelet count, hematocrit, and hemoglobin levels were considered. Two different evaluations of CD34+ cell counts were determined for each donor: baseline (before granulocyte colony-stimulating factor [G-CSF] administration) and in PB after G-CSF administration on the morning of the fifth day (day 5)...

BACKGROUND: There are several studies on prevalence of individual infectious disease markers (mono-infection) in donors but none on prevalence of coinfection. Co-infection is significant as it leads to accelerated disease progression. We, therefore, evaluated the prevalence of co-infection among blood donors. MATERIALS AND METHODS: The cross-sectional analysis was conducted in blood donors. All donors were tested for anti-HIV I and II, HBsAg, anti-HBC IgM, anti-HCV, Malaria and syphilis by chemiluminescence and ID-NAT assay...

Human T-lymphotropic virus type-1 (HTLV-1) infection was diagnosed in a Thai patient with chronic progressive myelopathy. The phylogenetic tree of the ltr sequencing of HTLV-1 indicated the virus belongs to the Transcontinental genotype of the Cosmopolitan subtype A. This is the first case report of HTLV-1-associated myelopathy in South East Asia. Awareness of HTLV-1 and related condition should be encouraged in this region and routine screening should be applied in blood donor.

Oral cancer is an important cause of cancer morbidity and mortality globally and exposure to trace metals alongside tobacco, alcohol and HPV are the important etiological factors in its development. Selected essential and toxic trace metals (Cd, Cr, Cu, Fe, Mn, Ni, Pb and Zn) were measured in the blood, scalp hair and nails of oral cancer patients and counterpart controls by atomic absorption spectrometry. Mean concentrations of Cd, Ni and Pb were found to be significantly higher (p<0.05) and those of Cu, Fe and Zn were considerably lower in the blood, scalp hair and nails of the patients than the controls...

Compatible pairs of living kidney donors and their intended recipients can enter into kidney paired donation (KPD) and facilitate additional living donor kidney transplants (LDKTs). We examined 11 compatible pairs (the intended recipients and their intended, compatible donors) who participated in KPD, along with the recipients' 11 matched, exchange donors. The 11 pairs participated in 10 separate exchanges (3 were multi-center exchanges) that included 33 total LDKTs (22 additional LDKTs). All the intended donors were blood group O and female, with a mean living kidney donor profile index (LKDPI) of 27...

Several reports have described the presence of antibodies against Alzheimer's disease-associated hyperphosphorylated forms of tau in serum of healthy individuals. To characterize the specificities that can be found, we interrogated peripheral IgG(+) memory B cells from asymptomatic blood donors for reactivity to a panel of phosphorylated tau peptides using a single-cell screening assay. Antibody sequences were recovered, cloned, and expressed as full-length IgGs. In total, 52 somatically mutated tau-binding antibodies were identified, corresponding to 35 unique clonal families...

BACKGROUND: Biliary complications are important during liver transplantation because of their effect on recipient and graft survival, incidence, and the long treatment period. These complications are associated with 50% morbidity and 30% mortality rates in recent studies. One of the most important reasons for biliary anastomosis complications is arterial ischemia. We present the results of our telescopic biliary anastomosis technique performed on the mucosa of the main biliary duct. PATIENTS AND METHODS: Fifty-six cases of telescopic biliary reconstruction were performed in 203 patients during 2015...

BACKGROUND: Most patients have serious digestive complications after renal transplantation. Therefore, it is important to protect gastrointestinal function to improve the survival rate of transplant patients. Proton pump inhibitors (PPIs) such as lansoprazole and rabeprazole are widely administered to renal transplant patients with mycophenolic acid (MPA) in the perioperative period. PPIs are metabolized by cytochrome (CYP) 2C19 enzymes. Mycophenolate sodium (MYF) and mycophenolate mofetil (MMF) have been used in immunosuppression...
