OBJECTIVES: To assess the attitude towards voluntary non-remunerated blood donation among blood donors in Trinidad and Tobago (TRT). BACKGROUND: Blood donors in TRT are either family replacement (F/R, 87%) or remunerated (13%). There is chronic blood shortage and high seroreactivity for transfusion-transmissible infections (TTI) in donors. Converting existing to voluntary non-remunerated donors (VNRD) reduces the need to recruit news donors in achieving 100% VNRD...

The Zika virus is a positive sense, single-stranded RNA arbovirus in the Flaviviridae family, genus Flavivirus. This virus was initially isolated in Africa and is transmitted to nonhuman primates and humans by mosquitoes. Initial reports describe sporadic mild viral infection with fever, arthralgia, myalgia and conjunctivitis in Africa and Asia. However, its geographic distribution has significantly increased, and it has caused large outbreaks in the Yap Islands in 2007, in French Polynesia in 2013 and in Brazil in 2015...

BACKGROUND: The predominant mode of transmission of human immunodeficiency virus (HIV) in Europe is male-to-male transmission. Men who have sex with men (MSM) are deferred from donating blood in many countries, but nevertheless do donate blood. Based on data from 34 countries, we estimated the proportion of MSM screened for HIV in the context of a blood donation and identified individual factors associated with this HIV screening in order to propose possible public health interventions...

Over 110 million units of blood are collected yearly. The need for blood products is greater in developing countries, but so is the risk of contracting a transfusion-transmitted infection. Without efficient donor screening/viral testing and validated pathogen inactivation technology, the risk of transfusion-transmitted infections correlates with the infection rate of the donor population. The World Health Organization has published guidelines on good manufacturing practices in an effort to ensure a strong global standard of transfusion and blood product safety...

: 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 male to female) and parenterally (transfusions, injection drug use and transplants)...

BACKGROUND: Blood donation screening detecting only antibodies fails to identify donors in the earliest stage of infection, before a detectable immunologic response, that is, the "window period" (WP). We present data on WP donations identified during prospective screening for Babesia microti, a transfusion-transmissible parasite of increasing concern in the United States. STUDY DESIGN AND METHODS: Blood donations collected in Connecticut, Massachusetts, Minnesota, and Wisconsin were screened using polymerase chain reaction (PCR) and arrayed fluorescence immunoassay (AFIA) to detect B...

BACKGROUND: Hepatitis E virus (HEV) is a leading cause of acute icteric hepatitis and acute liver failure in the developing world. During the last decade, there has been increasing recognition of autochthonous (locally acquired) HEV infection in developed countries. Chronic HEV infection is now recognised, and in transplant recipients this may lead to cirrhosis and organ failure. AIM: To detail current understanding of the molecular biology of HEV, diagnostic and therapeutic strategies and propose future directions for basic science and clinical research...

AIM: Malaria parasite is usually transmitted to humans by Anopheles mosquitoes but it can also be transmitted through blood transfusion. Usually malaria transmission is low in African urban settings. In West Africa where the P. falciparum is the most predominant malaria species, there are limited measures to reduce the risk of blood transfusion malaria. The aim of this study was to evaluate the prevalence of P. falciparum malaria carriage among blood donors in the National Blood Center of Bamako, capital city of Mali...

BACKGROUND: Bacterial contamination of blood components remains a major cause of sepsis in transfusion medicine. Between 2006 and 2010 in the 5 years before the introduction of bacterial screening of platelet (PLT) components by National Health Service Blood and Transplant (NHSBT), seven cases of PLT component-associated transmission of bacterial infection were recorded for 10 patients, three of which were fatal. STUDY DESIGN AND METHODS: Sampling of individual PLT components was undertaken at 36 to 48 hours after donation and tested in the BacT/ALERT system with 8 mL inoculated into each of aerobic and anaerobic culture bottles...

BACKGROUND: The parasitic Chagas disease is caused by the protozoan Trypanosoma cruzi, which is mainly transmitted by insect vectors. Other infection routes, both in endemic and in nonendemic areas, include organ and marrow transplantation, congenital transmission, and blood transfusion. Asymptomatic chronic chagasic individuals may have a low and transient parasitemia in peripheral blood and, consequently, they can unknowingly transmit the disease via blood transfusion. Riboflavin and ultraviolet (UV) light pathogen reduction is a method to reduce pathogen transfusion transmission risk based on damage to the pathogen nucleic acids...

Since local mosquito-borne transmission of Zika virus was first reported in Brazil in early 2015, the virus has spread rapidly, with active transmission reported in at least 61 countries and territories worldwide, including the United States. Zika virus infection during pregnancy is a cause of microcephaly and other severe brain anomalies. The virus is transmitted primarily through the bite of an infected Aedes mosquito, but other routes of transmission include sexual, mother-to-fetus during pregnancy, mother-to-infant at delivery, laboratory exposure, and, possibly, transfusion of blood products...

To evaluate the virological safety of blood components provided by the Niamey blood transfusion center after undergoing rapid tests. Samples found negative with rapid tests (n = 222) were screened by the Abbott Prism assay. Positive samples were confirmed by appropriate methods. Of 222 samples, nine (4.1%) were reactive for all markers. After confirmation, seven samples were positive (i.e., 3.2% false-negative results) : five (2.3%) for the surface antigen of hepatitis B (HBsAg) and two (0.9%) for the antibody directed against the hepatitis C virus (HCV-Ab)...

BACKGROUND: Transfusion-mediated human parvovirus B19 (PVB19) infection is rare but often causes severe hematologic disorders. In Japan, routine blood donor screening for PVB19 antigen (detection sensitivity, 10(6.4) IU/mL) using a chemiluminescent enzyme immunoassay (CLEIA) was introduced in 2008. However, there is no consensus on the minimal infectious dose of PVB19 permissible for red blood cells (RBCs). CASE REPORT: A 64-year-old man, who had received hemodialysis for diabetic nephropathy for 5 years, underwent an RBC transfusion for anemia caused by hemorrhagic enterocolitis...

Discovered in 1947 in a monkey in the Zika forest of Uganda, Zika virus was dismissed as a cause of a mild illness that was confined to Africa and Southeast Asia and transmitted by Aedes mosquitoes. In 2007, Zika virus appeared outside of its endemic borders in an outbreak on the South Pacific Island of Yap. In 2013, Zika virus was associated with a major neurological complication, Guillain-Barré syndrome, in a larger outbreak in the French Polynesian Islands. From the South Pacific, Zika invaded Brazil in 2015 and caused another severe neurological complication, fetal microcephaly...
