Background: To further minimize transmission risk of blood-borne viral and prion diseases, manufacturers of therapeutic animalor human-derived proteins have implemented improved in-process pathogen-removal procedures. Objectives: To evaluate removal of transmissible spongiform encephalopathy agents (prions) and viruses using Omega 100K VR membrane filtration system (Pall Filtron, Northborough, ...

Although xenotropic murine leukemia virus-related virus (XMRV) has been regarded as a laboratory contaminant, it remains one of the most controversial viruses. The objective of the study was to determine if XMRV is present in 44 patients with beta-thalassemia major, 48 with sickle cell disease, and 89 volunteer blood donors. After RNA/ DNA extraction from plasma/buffy coat the samples were scre...

In 2006, a new retrovirus was isolated from prostate cancer patient tissue. Named xenotropic murine leukemia virus-related virus (XMRV), this was potentially the third class of retrovirus to be pathogenic in humans. XMRV made a more dramatic impact on the wider scientific community, and indeed the media, in 2009 when it was reported to be present in a remarkably high proportion of patients with...

The gammaretroviruses xenotropic murine leukemia virus (MLV)-related virus (XMRV) and MLV have been reported to be more prevalent in plasma and peripheral blood mononuclear cells of chronic fatigue syndrome (CFS) patients than in healthy controls. Here, we report the complex analysis of whole blood and plasma samples from 58 CFS patients and 57 controls from Canada for the presence of XMRV/MLV ...

We investigated the prevalence of xenotropic murine leukemia virus-related virus (XMRV) among 293 participants seen at academic hospitals in Boston, Massachusetts. Participants were recruited from the following 5 groups of patients: chronic fatigue syndrome (n = 32), human immunodeficiency virus infection (n = 43), rheumatoid arthritis (n = 97), hematopoietic stem-cell or solid organ transplant...

A xenotropic murine leukemia virus-related virus (XMRV) has recently been reported in association with prostate cancer and chronic fatigue syndrome, with a prevalence of up to 3.7% in the healthy population. We looked for XMRV in 230 patients with human immunodeficiency virus type 1 or hepatitis C infection. XMRV was undetectable in plasma or peripheral blood mononuclear cells by polymerase cha...
