Treatment of a hepatitis. Hepatitis B.

Hepatitis B. The description of disease.

Hepatitises virus - the infectious diseases, described a primary lesion of the liver, proceeding with an intoxication and in some cases with an icterus. Are surveyed as some independent illnesses:

virus hepatitis A (a synonym: an infectious hepatitis, an infectious disease)
virus hepatitis B (a synonym a serumal hepatitis)
virus hepatitises "neither A, nor B"

Virus Hepatitis B. Has diameter about 42 nanometers, consists of the two-spiral DNA surrounded by a double environment. 3 specific antigens of the originator are known:

Superficial antigen HBsAg earlier referred to as the Australian antigen since for the first time it is allocated in 1964 �.S. Blumberg from a blood of aboriginals of Australia. In the further it is identified as a specific marker of a virus of a hepatitis of �entury It it is found out in hepatocytes, a blood and other biological liquids.
The Core antigen HbcAg is taped only in hepatocytes.
the Antigen of infectious HBeAg circulates in a blood in structure of particles Dane, in a free kind or in connection with an immunoglobulin.

Sources of a contagium are patients acute and chronic forms of disease, and also the face with subclinical current of infectious process and healthy bearers. Patients become infectious from the end of an incubation interval. The carriage of virus can be lifelong. Transfer of the originator is carried out through a blood, and the infecting dose makes 0,0005-0,001 ml.

Infection occurs artificial and natural ways. From artificial ways the most important is the hemotransfusion and its preparations (plasma, a fibrinogen). The albumin, a gamma-globulin practically are not infectious. Infection is possible at use not enough the sterilized syringes, needles, surgical and stomatologic toolkit.

In natural conditions transfer of a virus is carried out sexual by , and also during labors from infected mother to the newborn at passage through sexual ways. The so-called vertical way of infection of a fetus to III trimester of pregnancy is possible.

The Susceptibility of the person to to a virus of a hepatitis In high. Seasonal prevalence and periodicity of a case rate are absent. The high case rate is recorded among narcomaniacs, faces of the medical trades having contact to a blood.

Treatment of a hepatitis. Hepatitis B.

Treatment of hepatitis B same, as well as at a virus hepatitis A. At threat or development of a hepatic coma apply high doses of corticosteroids, inhibitors of proteases, spend a hemosorption, a hyperbaric oxygenation.

The Dispensary observation for had been ill spend within 1 year. Within 6-12 months it is necessary to limit exercise stresses, women within 1 year are recommended to avoid pregnancy. Carried a virus hepatitis In preventive inoculations (except for inoculations against a tetanus and a rabies) are counter-indicative.

The Forecast in most cases favorable, disease comes to an end with full convalescence, regarding cases the residual phenomena are observed. Approximately at 10 % of patients with an outcome the chronic persistent or chronic active hepatitis develops in a cirrhosis of a liver. A lethality nearby 1 %.

Prophylaxis. The account of the faces which have carried a virus hepatitis In, and the faces adjoined them is necessary. This contingent should be excluded from among donors.
