background: hepatitis a virus (hav) is a single strand and non-enveloped rna virus. it is usually transmitted by the fe­cal-oral and the blood transfusion routes and causes the hepatitis a disease. clinically, the hepatitis a is usually mild, par­ticularly in children, in whom it is frequently subclinical. the disease is more serious and prolonged in adults. the objective of this study was to f...

conclusions the analysis indicates that the hev isolated from blood donors in the southwest of iran belongs to genotype 1. however, more samples from other geographic regions of iran are needed to confirm these findings. because transmission of hev by administration of blood or blood components is likely to occur, it may be sensible to screen donor blood for hev to eliminate transfusion-transmi...

OBJECTIVE To determine the prevalence of GB virus-C (GBV-C) RNA and TT virus (TTV) DNA in patients with systemic sclerosis (SSc), rheumatoid arthritis (RA), and osteoarthritis (OA) as well as to compare the autoantibody pattern in patients with SSc with and without evidence of viral infection. PATIENTS AND METHODS The study included 168 patients (84 SSc, 41 RA, and 43 OA) diagnosed according ...

The aim of this study is to present the status of transfusion –transmitted infections among the apparently healthy donors so as to increase the awareness of complications of blood transfusion and make the clinicians more vigilant with regard to judicious use of blood. A total of 5008 units of donor’s blood was screened from January 2006 to December 2008 at blood bank of People’s Hospital, Bhopa...

Blood transmitted infection is the commonest cause of death after blood transfusion. All patients on regular packed cell volume (PCV) or any blood component are at increased risk of transfusion transmitted infections. The etiological agents can be virus, bacteria or protozoa. These organisms can cause clinical sickness in recipient, can persist in him as carrier state or can cause asymptomatic ...

BACKGROUND CONTEXT Previous studies have shown that modern intraoperative blood-saving techniques dramatically reduce the allogeneic transfusion requirements in surgery for adolescent idiopathic scoliosis (AIS). No studies have looked at the pattern of postoperative hemoglobin (Hb) in AIS patients undergoing corrective spinal surgery and correlated this with the timing of allogeneic transfusion...

Patients who undergo dialysis treatment or a renal transplant have a high risk of blood-borne viral infections, including the Torque teno virus (TTV). This study identified the presence of TTV and its genome groups in blood samples from 118 patients in dialysis and 50 renal-transplant recipients. The research was conducted in a hospital in the city of Maringá, state of Paraná. The viral DNA, ob...

We provide a comprehensive review of risks associated with allogeneic red blood cell and platelet transfusions in Canada. The review focuses on clinically symptomatic noninfectious transfusion risks (acute and delayed hemolytic, febrile nonhemolytic [FNHTR], allergic, volume overload, transfusion-related acute lung injury, graft-versus-host disease, and posttransfusion purpura) and the risk of ...

Ten years after the identification of the first partial sequences of Torque teno virus (TTV), more than 200 full-length related genomes have been characterized in humans and in several animal species. As suspected in the earlier stages of their description, a considerable genetic variability characterizes TTV and related viruses, the current members of the floating genus Anellovirous. Since inf...
