BACKGROUND: Little is known regarding transfusion-transmitted leishmaniasis (TTL) and the real global incidence of visceral leishmaniasis (VL) among blood donors as carriers of Leishmania spp. in endemic VL foci including Iran. Recent epidemiological evidences indicate that blood donor may be harbor of Leishmania infantum (L. infantum) infection in Iran. METHODS: The aim of the present study was to determine the prevalence of Leishmania infection among blood donors in a main endemic focus of VL in Iran using DAT and polymerase chain reaction (PCR) based methods Between July-September 2016, blood samples were collected from 600 apparently healthy blood donors from six blood donation centers and blood donation mobile unit in Ardabil Province, where VL cases had been recorded...

INTRODUCTION: Despite prophylaxis, a small proportion of RhD-negative women may develop anti-D antibodies after a sensitizing event occurring during pregnancy or delivery of a D-positive baby. Intrauterine transfusion (IUT) is the treatment of choice in case of fetal anemia, but it cannot be performed early during pregnancy. Combined treatment with therapeutic plasma-exchange (TPE) and intravenous immunoglobulin (IVIG) can avoid or delay IUT. Immunoadsorption (IA) could represent a more effective treatment in selected cases...

Infused CD34 cell count has a significant impact on transplant outcome. In this retrospective study, we aimed to analyze the impact of donor iron parameters on peripheral blood stem cell (PBSC) collection. A total of 303 related donors were included in the study. The mobilization regimen, recombinant G-CSF, was given for four consecutive days. A CD34(+) cell count below 2×10(6)/kg was defined as mobilization failure which was demonstrated in 23 donors (7.6%). Mobilization failure was more frequent in female donors than male donors (13...

Transfusion medicine plays a vital role in the supportive care of patients receiving therapy for hematology, oncology and hematopoietic stem cell transplants (HSCT). With advances in therapy with more intensive chemotherapy or radiotherapy, patients usually develop cytopenias and need frequent transfusion support with packed red blood cells, granulocyte transfusion or platelets to support them until they recover from the effect of therapy. HSCT poses unique challenges for transfusion medicine, since transplant recipients may require substantial transfusion support due to cytopenias associated with toxic medications, decreased marrow reserve, infection or their malignancy...

Our microbiota is determined by many variables including ABO blood groups. The microbiota is not only confined to the gut and skin but is also recoverable from blood of healthy donors. The microbiota shape our immune system through cross reactivity with antigens, the expression of direct molecular patterns, the release of cytokines, the effects on nutrients and micronutrients and even through an interplay with epigenetics. It is likely, therefore, that a donor's microbiota could alter the antigenicity of blood and its components and potentially contribute to transfusion-related immune modulation [TRIM]...

Blood and blood-component therapy triggers immunological reactions in recipients. Transfusion-related immunomodulation [TRIM] is an important complex biological immune reaction to transfusion culminating in immunosuppression. The mechanisms underlying TRIM include the presence of residual leukocytes and apoptotic cells, the transfusion of immunosuppressive cytokines either present in donor components or generated during blood processing, the transfer of metabolically active growth factor-loaded microparticles and extracellular vesicles and the presence of free hemoglobin or extracellular vesicle-bound hemoglobin...

The painful vaso-occlusive crisis is the most common acute manifestation of sickle cell disease resulting in poor quality of life and high utilisation of hospital facilities. The main disease modifying strategy is treatment with hydroxycarbamide. For patients intolerant or who fail hydroxycarbamide, chronic transfusions are an alternative. Automated red cell exchange transfusion (ARCET) are more effective in lowering rapidly the HbS level while avoiding iron overload. As they require specialised equipment and specially trained staff while utilising higher volumes of blood, there have been concerns regarding the costs involved...

Blood transfusion is a clinical replacement therapy with many successes with some benefit and, also, some harm. Cancer is a multifaceted disease potentially associated with the immune system's weakness where the cancerous tumor cells escape from the immune system. Allogeneic blood transfusion, through five major mechanisms including the lymphocyte-T set, myeloid-derived suppressor cells (MDSCs), tumor-associated macrophages (TAMs), natural killer cells (NKCs), and dendritic cells (DCs) can help the recipient's defense mechanisms...

Anemia is present in more than half of cancer patients and appears to be an independent prognostic factor of short- and long-term adverse outcomes. It increases in the advanced period of cancer and perioperatively, in patients with solid tumors who undergo surgery. As a result, allogeneic red blood cell (RBC) transfusion is an indispensable treatment in cancer. However, its safety remains controversial, based on several laboratory and clinical data reporting a linkage with increased risk for cancer recurrence, infection and cancer-related mortality...

The transfusion of platelet concentrates prepared from allogeneic single or pooled donations is a standard procedure in transfusion medicine to stop or prevent bleeding in cancer patients with thrombocytopenia undergoing surgery, chemotherapy and/or radiotherapy. While platelet transfusion may appear reasonable in many instances, greater scientific and medical attention should however be given to the possibly insidious impact of transfused platelets on the outcome of cancers. Indeed platelets and the microvesicles they release possess all the biological ingredients capable of supporting tumor growth, protecting circulating tumor cells, and to contributing to metastatic invasion...

Oncology services utilize about 15% of the blood transfusion resources in the USA. Red blood cell transfusion is performed immediately before, during or after major surgery to compensate for blood loss and hemodilution. However, a lack of evidence-based guidelines leads to variable transfusion practices among clinicians. The benefits of transfusing blood products are obvious in life-threatening low blood cell counts or bleeding, but it is becoming apparent that deliberate blood transfusion in some cancer patients can trigger negative clinical impacts...

Nurses are an essential partner in the treatment of complex diseases and they have extensive influence on patient outcomes. Connecting a patient to a machine takes courage, skill, and a whole lot of trust. Anyone who has earned the title of "nurse" has shown courage. Skill comes with hours and hours of practice. Trust is earned and ongoing. Combine these three attributes and you get the "care" that goes into nursing care. Low-density lipoprotein (LDL) apheresis is a well-established therapy for hypercholesterolemia...

Thrombotic diseases caused by cancer progression have been reported as one of the major causes of cancer associated morbidity and mortality along with cancer invasiveness and infectious complications. Moreover, anticoagulant therapy with heparin and heparin-like drugs, or vitamin K antagonists, or the Direct Oral Anticoagulants, is seeing an extended application in cancer patients and offers prolonged life expectancy to oncology patients for whom blood activation and thrombotic events have a variable incidence, depending on cancer type...

The voluntary, unpaid, altruistic blood donor is a cornerstone of current transfusion medicine. The complexity of medical and ethical issues related to blood donation and hemochromatosis has led to a large number of studies related to the safety of the hemochromatosis donor and the quality of the blood components produced from these donations. The issue of accepting persons with HC as blood donors is diverting, both in Europe and worldwide and without joint guidelines. A questionnaire-based study was performed and mailed to all 25 blood bank leaders in Norway...

Von Willebrand disease (vWD) is the most common inherited bleeding disorder. Its association with pregnancy is infrequent. Here we report three cases of vWD associated with pregnancy. The clinical features of this combination are very suggestive. However, difficulties are still encountered during the diagnosis process. The first case was diagnosed for the first time during the patient's second pregnancy despite several episodes of vaginal bleeding and suggestive clinical symptomatology. The second case was diagnosed during childhood and the patient was properly managed during this pregnancy...

In B(A) phenotype, an autosomal dominant phenotype, there is a weak A expression on group B RBCs. We herein report a case of a probable B(A) phenotype in a first time 20-year old male donor. The cell and serum grouping were done using tube technique and also with blood grouping gel card (Diaclone, ABD cards for donors, BioRad, Switzerland). The antisera used were commercial monoclonal IgM type. To check for the weak subgroup of A, cold adsorption and heat elution was performed. The cell grouping was AweakB RhD positive while the serum grouping was B...
