The term hepatitis is derived from the Greek words "Hepar (liver) and" itis "(inflammation) from. "Sometimes the disease is caused by medications, but usually by viruses," said Thomas Berg, hepatologist at the Charité.
HBV is particularly dangerous for two reasons: Unlike, say, the hepatitis A virus can lead to chronic inflammation, which is dangerous, but will remain hidden long. And unlike for example the hepatitis C virus is easily transmitted through sex. Anyone who is infected, in which the virus is found in the blood and, in men, even in the semen. About minor injuries in the skin and mucous membrane, it can get from unprotected sex in the other body. By razors or nail scissors, with which it deals are tiny injuries, HBV can be transmitted, as well as by injecting equipment, tattooing and piercing equipment.
The virus consists of a round shell of fat and placed in storage proteins, a protein-icosahedron (icosahedron) and including Finally, a core, in which the DNA content. Alone would not be the virus survive, they need the people and especially the liver cells to proliferate. To this end, they smuggle themselves - as well as other viruses - in the cells and use their infrastructure. Special feature: If one is infected with HBV for the first time, you will never get rid of the virus, because it is in the nucleus of the host cell sets and survived there.
It can take months to occur after infection, the first symptoms: headache, fever, weight loss and a yellow skin and eyes. In about two thirds of the cases are from these symptoms, however. Very often heals acute hepatitis B, even without major complications and without taking antibiotics. Tricky is that it is chronic in up to ten percent of those affected is the liver and gradually, over years and decades, damages. Particularly common causes of chronic variant, when children infected at birth with their HBV-infected mother.
even liver cancer caused by HBV. Since the virus after a cured disease throughout the body sleeps, it can strike again, and then all the more - namely, when the immune system is weakened, for example, by chemotherapy or AIDS. Bjorn Rosen
