How the test is performed Return to top Adult or child: Blood is drawn from a vein ( venipuncture ), usually from the inside of the elbow or the back of the hand. The puncture site is cleaned with antiseptic, and a tourniquet (an elastic band) or blood pressure cuff is placed around the upper arm to apply pressure and restrict blood flow through the vein. This causes veins below the tourniquet to distend (fill with blood). A needle is inserted into the vein, and the blood is collected in an air-tight vial or a syringe. During the procedure, the tourniquet is removed to restore circulation. Once the blood has been collected, the needle is removed, and the puncture site is covered to stop any bleeding

Extractions: Background Epstein-Barr virus (EBV) infects resting B-lymphocytes and transforms them into immortal proliferating lymphoblastoid cell lines (LCLs) in vitro . The transformed immunoblasts may grow up as immunoblastic lymphomas in immuno-suppressed hosts. Results Conclusion We suggest that EBNA-3 by direct protein-potein interaction induces the nuclear accumulation of a novel enzyme, that is part of the ribonucleotide salvage pathway. Increased intranuclear levels of UK/UPRT may contribute to the metabolic build-up that is needed for blast transformation and rapid proliferation.

September 27, 2000 What Is The Epstein-Barr Virus And Who Can Become Infected? The Epstein-Barr virus (EBV) is a member of the herpes virus family. Approximately 90 to 95 percent of individuals over age 30 have been exposed to the virus, often without knowing it, because it causes no overt or obvious infection in a large number of cases. EBV is most commonly transmitted from person-to-person with saliva. It has the widest range of illness associated with it of any infectious agent we deal with these days. The virus is most frequently associated with infectious mononucleosis in the minds of physicians and the public. Only about a third of people in the world who have antibodies to EBV or who have been infected with the virus, however, have ever had infectious mononucleosis. On the other hand, many different infectious agents can cause infectious mononucleosis.

September 27, 2000 Is Epstein-Barr Virus Associated With Cancer? Yes, the virus has been associated with a number of cancers, but nobody is ready to say it causes them. It was first found in a tumor called African Burkett's lymphoma, a cancer of the lymphoid cells of the head and neck found mostly in African males. The Epstein-Barr virus is present in about 95 percent of those tumor cells, but exactly how it got there and what role it plays is still unknown. The virus is also present in a smaller percentage of so-called American Burkett's lymphomas. Other B-cell tumors besides Burkett's lymphomas that contain EBV are Hodgkin's disease and non-Hodgkin's lymphomas. It is also present in T-cell lymphomas and nasopharyngeal carcinoma. They very recently identified it in breast cancer, but they don't know what it does. It could be that when the breast cells are undergoing replication they become altered, making it easier for the virus to get in.

Raymond P Stowe, Ph.D Space Flight-Induced Reactivation of Latent Epstein-Barr Virus ( E-Barr Previous studies have demonstrated that cellular immunity during and after spaceflight is significantly decreased. The mechanisms underlying this phenomenon are not well understood, but it has been proposed that physical and psychological stress (i.e., launch and landing stresses, microgravity, confinement, separation from family, sleep deprivation, etc.) may be major mediating factors in the impaired immune response of astronauts. Notably, stress can downregulate cellular immunity resulting in increased susceptibility to infections and delayed wound healing. Herpesviruses, in particular, are reactivated by stress.

Extractions: : HHV-4 Search Epstein-Barr Virus (EBV/HHV-4) HHV-4 has a dual cell tropism for human B-lymphocytes (generally non-productive infection) and epithelial cells (productive infection). There is no suitable animal host, but replication/latency has been studied extensively in transformed human cell lines. HHV-4 is widespread worldwide, with ~75% of UK adults infected (lifelong!): The usual outcome of infection is polyclonal B-cell activation and benign proliferation, which may be sub-clinical or produce infectious mononucleosis (glandular fever): Disease: Comments: Infectious mononucleosis ("glandular fever") Primary infection, self limiting. Occurs in ~50% of primary infections of adolescents and young adults. Burkitt's lymphoma Hodgkin's disease Sporadic lymphoma; latent HHV-4 found in ~50% of cases. B-lymphoproliferative disease Lymphoproliferative disease/lymphomas, almost exclusively in the immunocompromised host, especially post-transplant (as a result of immunosuppressive drug therapy) and in AIDS. Might occur in primary infection or persistent infection. X-linked lymphoproliferative syndrome Rare genetic immune dysfunction results in fatal primary infection (see below).

Extractions: the genome is large enough to code for 100 - 200 proteins but only a few have been identified. The proteins characterized thus far fall into the following groups : A._Latent_proteins 1. EB viral nuclear antigen complex (EBNA) - EBNA is now known to be a complex of at least 6 proteins ie. EBNA 1-6. Their functions have yet to be understood but EBNA 1 is thought to be essential for the maintenance of the episomal state of EBV in infected cells and binds to the origin of replication. EBNA 1 is expressed in all known virus carrying cells, but its expression may be lost when a lytic cycle ensues. EBNA 2 has two phenotypes, A and B, strain A, which is found mainly in Caucasians, is more efficient in immortalizing B lymphocytes than strain B, which is mainly found in Africa. However, neither strains have any specific disease association. 2. Latent membrane protein (LMP)

Extractions: ADVERTISEMENT By Victoria Stagg Elliott AMNews staff. Jan. 28, 2002. There was a time when the measles was fingered as a cause of multiple sclerosis. That connection, though, was ruled out so long ago that the virus doesn't even make the list of likely suspects anymore. Then, during the mid-1990s, human herpesvirus 6 became a likely culprit. This virus's wayward cousin, herpes simplex 1, was also listed among the possible guilty parties, as were certain bacteria, such as Chlamydia pneumoniae frequently found on the scene. Some disease detectives also have questioned whether these suspects could have been working together or with some of the other 40 infectious agents implicated thus far in causing multiple sclerosis. Or maybe it was none of them at all. With this article

Extractions: News By Myrna E. Watanabe Virologist Hans Wolf of the University of Regensburg in Germany has been working on the etiology of nasopharyngeal carcinoma (NPC) in areas of China since 1979. Researchers from the U.S. National Cancer Institute (NCI), too, have been working with their Chinese colleagues on cancer epidemiology and etiology. The reasons for this cooperative research vary, but as Federico Welsch , associate director for international affairs at NCI, points out, "They have some cancers that are rare in the developed world." Among these are nasopharyngeal cancer, certain liver cancers, and esophageal cancer. Environmental factors have been implicated. Research by Wolf and Chinese colleagues Yi Zeng , chief of the department of tumor viruses at the Institute of Virology, Chinese Academy of Preventive Medicine (CAPM) and former president of CAPM, Shu-Yan Gu , now deputy director of the National Center for AIDS Prevention and Control, and others, is leading to development of a vaccine. But in some areas of the world, especially parts of Asia and Africa, "the people develop nasopharyngeal carcinoma," states Wolf. And in areas of Africa where there is a high prevalence of malaria, people infected with EBV may later develop Burkitt's lymphoma. The Chinese develop NPC. Only a small percentage of those infected ever develop this cancer, but it seems that infection with EBV is one of the essential risk factors. Zeng and his colleagues found evidence of an EBV gene and EBV proteins in in vitro cell lines developed from nasopharyngeal carcinomas and in cell lines developed from NPC cells transplanted into nude mice.

Extractions: Rubella vaccine linked to Epstein-Barr Virus Many people now know about the dangers of DPT shots in babies. and they are rejecting those particular shots. Yet, they still accept other vaccines for their children. So for those trusting souls, here is the latest evidence on the dangers of the German measles vaccine. A study of 200 patients with Epstein-Barr Virus (often called Yuppie disease) is scheduled for publication this spring in the journal Medical Hypothesis. In an advance report in the San Diego Tribune Biomedical researcher Allen D. Allen of Algorithms. Inc. of Northridge. California, blames EBV syndrome on Merck Sharp and Dohme’s Biavax and Meruvax vaccines which were introduced in the late 1970’s. Allen says. ‘I can say all this attention to the (Epstein-Barr) syndrome. the public awareness. started in the early 1980’s. right after these vaccines came out. Young adults. the ones most likely to be in contact with young children, are the primary targets. It’s too much of a coincidence to ignore." In a similar study. Dr. Hugh Fudenberg
