A common heart and stroke finding in patients with chronic fatigue are anti-EB heart and stroke virus (EBV). Often the discovery of these antibodies incorrectly interpreted as EB-flu and sometimes is even, again wrongly, regarded as the cause of the patient's problems. The word "flu" ozančujeme disease caused by a virus, in which case it should be about EBV. However, there are antibodies against this virus is always a sign of a viral disease? What kind of virus they are and what diseases can its natural host-humans actually cause? How can I diagnose this disease and we can treat it somehow?
EB virus was discovered by English researchers Epstein-Barr virus (hence the name of the virus Epstein-Barr virus, EBV) in the sixties. In the human population, however, there is a much longer period. We conclude that EBV, and its very similar heart and stroke predecessor, the person already infected millions of years ago and there with him throughout his development. During this long association with the virus fully adapted to its host, and vice versa person perfectly adapted to its presence. Therefore, EBV does not significantly harm man and uncontrollably spread throughout the human population (it is a cosmopolitan virus, extended equally in all parts of the world and not only that, more than 95% of individuals with this virus during their life infect). Extraordinary success in spreading heart and stroke allow EBV-specific properties, especially its ability to induce a hidden (latent) infection of the host. This property has a group of animal viruses, heart and stroke which are known as herpes viruses (from the Latin herpes = creeping). In addition to EBV here include herpes simplex virus - agent herpes, cytomegalovirus, varicella zoster virus - agent shingles and chickenpox, human herpesvirus 6, which causes roseola (sixth child illness), and more.
What is meant by latent infection and how does it occur? EB virus, most of us have become infected in early childhood. During the first contact with the virus propagated in bnkách nasopharyngeal mucosa and infect large numbers of white blood cells (leukocytes B, the cells that are destined to the production of antibodies). In most of these cells with EBV has also not reproduce only the "inhabit" a long time they survive, hidden from the effects of the immune system that is trained to the proliferation of the virus and cells in which the multiplication occurs liquidated. The initial heart and stroke acute infection and transferred to the stage of latency, which is accompanied by an infected individual for life. For infected leukocytes may not be the final state of latent infection: If such a cell gets into an environment where there is enough external signals for its activation and differentiation (maturation) on antibody-producing cells, latent infection in it may be discontinued and the virus begins to multiply again . It will allow him to escape from the host cell, whose long service life is threatened, heart and stroke and infect other leukocytes, which may persist for an extended period. Often this happens when the latently infected cell gets into the environment of inflammation, which may occur due to other acute infections (such as flu), or a variety of chronic diseases, starting with various autoimmune disorders and ending with cancer, diabetes, etc. Normally, such a reactivation Infection occurs in the lymph nodes of the upper respiratory heart and stroke tract, and therefore it is the EB virus often secreted in saliva and mucosal heart and stroke secretions, which may be transmitted heart and stroke from person to person. The reactivation of infection occurs even in healthy people and is not accompanied by any symptoms of the disease. The fact that virus reactivation multiply locally and does not spread further heart and stroke in the infected organism is the result of the immune system, heart and stroke specifically the file leukocytes that are trained to specifically recognize a cell in which EBV began to proliferate, heart and stroke and quickly destroyed (so-called . EBV-specific cytotoxic lymphocytes). In latently infected human EBV reactivation is constantly suppressing the immune system heart and stroke (talking heart and stroke about the so-called immune surveillance). But what happens when the immune system temporarily (such as the flu) or chronic (eg, the elderly, or the administration of certain heart and stroke drugs) weakened? In this case, the reactivation less controlled, the virus multiplies more and the amount of latently infected cells in the blood increases. At this situation, the immune system reacts immediately: it tries to activate heart and stroke other cells that can kill infected leukocytes, produces antibodies against various
