OBJECTIVES: Hemoglobin SC is the second most common variant of sickle-cell disease worldwide, after hemoglobin SS. The objectives of the study were to describe the clinical and laboratory characteristics of hemoglobin SC disease in children from a newborn screening program and treated at a blood donor center. METHODOLOGY: This study assessed a cohort of 461 infants born between 01/01/1999 and 12/31/2012 and followed-up until 12/31/2014. Clinical events were expressed as rates for 100 patient-years, with 95% confidence intervals...

BACKGROUND: Critically ill preterm very-low-birthweight (VLBW) neonates (birthweight ≤ 1.5 kg) frequently develop anemia that is treated with red blood cell (RBC) transfusions. Although RBCs transfused to adults demonstrate progressive decreases in posttransfusion 24-hour RBC recovery (PTR24 ) during storage-to a mean of approximately 85% of the Food and Drug Administration-allowed 42-day storage-limited data in infants indicate no decrease in PTR24 with storage. STUDY DESIGN AND METHODS: We hypothesized that PTR24 of allogeneic RBCs transfused to anemic VLBW newborns: 1) will be greater than PTR24 of autologous RBCs transfused into healthy adults and 2) will not decrease with increasing storage duration...

The US Department of Defense recently made the decision to open direct ground combat roles to women. Blood product transfusion is an essential component of the US Military guidelines for tactical combat casualty care and damage control resuscitation, but blood transfusion carries with it the specific side effect of alloimmunization-a uniquely significant side effect for young women who may desire subsequent pregnancies. Presently to be considered are the changes that may need to be made to blood transfusion in the setting of battlefield medicine to optimally care for combat-injured women, as a majority of the existing data regarding the risks of transfusion in the trauma setting involve predominantly men...

BACKGROUND: Signal functions for emergency obstetric and newborn care (EmONC) are the major interventions for averting maternal and neonatal mortalities. Readiness of the facilities is essential to provide all the basic and comprehensive signal functions for EmONC to ensure emergency services from the designated facilities. The study assessed population coverage and availability of EmONC services in public and private facilities in Bangladesh. METHODS: An assessment was conducted in all the public and private facilities providing obstetric care in to in-patients 24 districts...

Lewis blood group antibodies, which are mostly naturally occurring and considered clinically insignificant, have rarely been documented as a cause of acute hemolytic transfusion reactions (AHTRs). This report presents two cases of AHTRs caused by anti-Lea occurring in postpartum black females (one group B, one group AB) whose pregnancies were complicated by preeclampsia. Neither anti-Lea was detected by automated solid-phase red cell adherence technology in pre-transfusion testing. Therefore, red blood cell units, compatible by electronic crossmatch, were issued and transfused...

BACKGROUND: Exchange blood transfusion (EBT) is a form of whole blood transfusion in which the total blood volume is replaced within a few hours. In perinatal and neonatal medicine, EBT is most often used in the management of severe anaemia or severe hyperbilirubinaemia in the first week of life. Hypocalcaemia, one of the common morbidities associated with EBT, is thought to arise from the chelating effects of the citrate commonly used as an anticoagulant in the donor's blood. This disorder manifests with muscular and nervous irritability and cardiac arrhythmias...

Background: The neonatal hemostatic system exhibits a fragile balance featuring lower levels of clotting factors as well as inhibitors. Neonatal platelets show in-vitro hypoaggregability, but neonates exhibit well-functioning primary and secondary hemostasis despite this impairment. Recently, polyphosphate shed by activated platelets has been shown to induce a prothrombotic shift on the plasmatic coagulation system of adults. The impact of platelet derived polyphosphate might differ in neonates due to aforementioned peculiarities...

Chronic hepatitis C (CHC) is caused by hepatitis C virus (HCV) infection. HCV infection causes acute hepatitis, and the majority of those infected progress to chronic hepatitis, and some of them develop cirrhosis and hepatocellular carcinoma. Transmission of HCV is parenteral, and the major transmission routes include drug abuse, insecure injections or medical procedures, contaminated syringes or needles, sexual contact with an HCV-infected person, vertical infection of newborns by infected mothers, the transfusion of blood or blood products contaminated with viruses, and organ transplants...

Neonatal jaundice or hyperbilirubinemia is a common occurrence in newborns. It can progress to develop kernicterus unless intervention is initiated. Severity and decision for management are usually based on serum bilirubin which needs blood sampling. Transcutaneous bilirubin measurement is a noninvasive technique and correlates closely with serum bilirubin. This Cross sectional study was done in the Department of Neonatology, Bangabandhu Sheikh Mujib Medical University from March 2013 to August 2014 to evaluate the transcutaneous bilirubin in comparison to serum bilirubin...

Sickle cell disease (SCD) represents one of the most common monogenic blood disorders worldwide, with an incidence of over 300,000 newborns affected per year. Reproductive challenges for men and women with SCD have been previously reviewed; however, evidence-based strategies to prevent and manage infertility and increase fecundity are lacking in women with SCD, which is one of the most important factors for quality of life. Areas covered: This review article summarizes the known risk factors for infertility, low fecundity, and premature menopause related to SCD...

Hemolytic disease of newborn (HDN) is a condition that develops in a fetus, when the IgG molecules produced by the mother pass through the placenta and attack the fetal red blood cells. HDN can occur due to Rh and ABO incompatibilities between the mother and the fetus as well as due to other allo-immune antibodies belonging to Kell (K and k), Duffy (Fya), Kidd (Jka and Jkb), and MNS (M, N, S, and s) systems. Role of intravenous immunoglobulin in management of HDN is not clear.SARA red blood cell antigen, first discovered in 1990 is a low frequency antigen...

BACKGROUND: Red blood cell (RBC) alloimmunization during pregnancy is still a major problem. Historically, anti-D antibodies are most likely to cause severe hemolysis, but other antibodies are also important. In Iceland, postnatal RhIg prophylaxis was implemented in 1969, universal RBC antibody screening was implemented in 1978, but antenatal RhIg prophylaxis is not yet routine. STUDY DESIGN AND METHODS: This nation-wide population study gathered data on alloimmunized pregnancies in Iceland between 1996 and 2015...

Rh immunoprophylaxis for Rh-negative women requires an understanding of terminology used for Rh blood typing laboratory reports. The pathophysiology of Rh hemolytic disease of the fetus and newborn was elucidated by studies in rhesus monkeys. Subsequent studies revealed that the human blood group antigen responsible for Rh hemolytic disease of the newborn (D antigen) is related to, but different from, the rhesus monkey antigen. Weak expression of the D antigen on red cells, originally termed D, is currently reported by laboratories as a "serologic weak D phenotype," which can be further defined by RHD genotyping to be either a weak D type or a partial D phenotype...

Gastric hemangioma in the neonatal period is a very rare cause of upper gastrointestinal bleeding. We present a case of hemangioma limited to the gastric cavity in a 10-day-old infant. A huge, erythematous mass with bleeding was observed on the lesser curvature side of the upper part of the stomach. Surgical resection was ruled out because the location of the lesion was too close to the gastroesophageal junction. Medical treatment with intravenous H2 blockers, octreotide, packed red blood cell infusions, local epinephrine injection at the lesion site, application of hemoclip, and gel-form embolization of the left gastric artery did not significantly alter the transfusion requirement...

: Human T-lymphotropic virus type 1 (HTLV-1) infection is a neglected disease despite roughly 15 million people are chronically infected worldwide. Lifelong less than 10% of carriers develop life-threatening diseases, mostly a subacute myelopathy known as tropical spastic paraparesis (TSP) and a lymphoproliferative disorder named adult T-cell leukemia (ATL). HTLV-1 is efficiently transmitted perinatally (breastfeeding), sexually (more from men to women) and parenterally (transfusions, injection drug user (IDU), and transplants)...

MNS antigen system is one of the human blood group systems. Anti-M antibody is a relatively common, naturally occurring antibody of IgM variety. Clinically significant anti-M antibody is reactive at 37°C in the anti-human globulin phase due to high thermal amplitude of IgM component or presence of IgG component. If anti-M antibody is activated at 37°C or in the anti-human globulin phase, it may cause delayed haemolytic transfusion reactions or haemolytic disease of newborn, which suggest variable clinical significance...

Rh is a complex blood group system with diverse genotypes that may encode weak and partial D variants. Standard serologic analysis may identify clinically significant D variants as D+; nevertheless, individuals with these D variants should be managed as D- patients to prevent antibody formation to absent D epitopes. Variant identification is necessary during pregnancy to allow for timely and appropriate Rh immune globulin (RhIG) prophylaxis for hemolytic disease of the fetus and newborn (HDFN) as D alloimmunization can occur with some D variants...

The blood group antigen Vel has been one of immunohematology's greatest enigmas: the variation in antigen strength from one individual to another, the property of anti-Vel to readily hemolyze Vel+ red blood cells (RBCs), and the difficulty to screen for sufficient numbers of Vel- blood donors had made Vel a tough nut to crack. In 2013, a small, previously unknown protein called small integral membrane protein 1 (SMIM1) was identified on the RBC by three independent research groups using different approaches, and all three groups demonstrated that Vel- RBCs lacked SMIM1...

Sickle cell disease is the most frequent genetic disease in France, concerning 400 newborns each year. The management of these Afro-Caribbean patients requires frequent transfusions from Caucasian donors. Due to important erythroid antigenic differences between Caucasian and African, the prevalence of allo-immunization is high in this population with a risk of transfusional impasse. Allogeneic stem cell transplantation is the only curative treatment for this disease and the replacement of red cells and lymphocytes of the sickle cell patient by those of the donor can also resolve the transfusional impasse...
