Hepatitis - an inflammatory diseaseliver, which occurs necrosis (death) of the liver tissue sections.
There are different causes of hepatitis.The following are the most common.
viruses.One of the main causes of the disease.Viral hepatitis - the result of infection by viruses gipatotropnymi, iethose that have an affinity with liver cells.There are different types of hepatitis viruses - A, B, C, D, E. They are characterized by means of transmission, the speed of development and symptoms of the disease, disease outcome.
Alcohol abuse.Prolonged use of alcohol often contributes to the emergence of alcoholic hepatitis.As a result of alcohol abuse occurs inflammation and destruction of liver cells.The dead cells are replaced by fat (fatty liver).
Medications.Some medications have side effects of the application of hepatotoxicity - the ability to cause inflammation and liver damage.In this case, it is
Violation of the outflow of bile from the liver (bile stasis).In this pathology develops cholestatic hepatitis.The liver produces bile, which is important for the metabolism of fats.In case of violation of the outflow of bile from the liver lobules, it stagnates in them.There is inflammation of the liver - cholestatic hepatitis.Often the disease is accompanied by gallstones (cholelithiasis), tumors of the gallbladder and pancreas.
There are different symptoms of hepatitis.The main ones are called the following symptoms:
arise as a result of penetration into the body of hepatotropic viruses that multiply only in liver cells.The source of infection is a sick man.In liver cells, viruses reproduce data, and then enter the blood stream.Hepatotropic viruses do not destroy the liver cells, and use them for its reproduction.
immune system of the human body detects infected cells and destroys them.As a result, viral hepatitis immune cells and cytotoxic substances secreted by them, liver cell damage.
first in the liver cells develop degenerative processes, it is a violation of their basic functions.Actively extending immune process leads to a large number of damaged cells.Violated function of the liver and hepatitis symptoms appear brighter.
If sufficient immune response, it is possible to get rid of the virus, and the patient is recovering.Most often this happens in hepatitis A and E, often with hepatitis B.
If the immune system is unable to cope with the virus, it stays in the liver.This is what happens in hepatitis C, sometimes with hepatitis B.
main mechanism of HCV infection - hematogenous (through the blood).Usually infection occurs during injection.Infection is possible if the tattoos, body piercing, when sharing toothbrushes, nail accessories, razors, the bite.In less developed countries, infection with hepatitis C may in dental offices, with the vaccination operations.
Analysis for hepatitis C include several laboratory blood tests - Biochemistry, for antibodies to C. For a more accurate diagnosis for hepatitis used analysis technique using polymerase chain reaction.
HCV treatment carries a specialist hepatologist.The basis for therapy of this disease are combined antiviral drugs.Most often in the treatment of hepatitis C using interferon alpha and ribavirin.The doctor individually, taking into account many factors, selects the appropriate dose of each medication and the duration of the reception.
the treatment of hepatitis C, in parallel with the primary therapy used supportive therapy.The patient is prescribed gepatoprotektory (drugs that restore liver function), immunomodulators.
It is very important to start hepatitis C treatment in a timely manner, without missing the initial stage of the disease.
Chronic hepatitis may develop after suffering a viral hepatitis, use of certain medications, the abuse of alcoholic beverages.The duration of the inflammatory process is more than six months.There are the following forms of chronic hepatitis.
chronic persistent hepatitis.Most patients do not feel this form of the disease.Complaints may be absent, slightly enlarged liver, jaundice does not happen.The disease can occur within a few years, without progression.With the right lifestyle may recover.
Chronic active hepatitis.It occurs after infectious hepatitis.Symptoms of this form of hepatitis are pain and heaviness in the right hypochondrium, appetite loss, nausea, fatigue, general weakness.Also in patients with the development of the disease increased body temperature, are subcutaneous hemorrhage, bleeding from the nose and gums, inflammation in multiple organs and joints.The course of chronic hepatitis B of this form of long-term, progressive.
chronic cholestatic hepatitis.Developed as a result of the stagnation of bile, an inflammatory process along the small bile ducts.In this form of chronic hepatitis B is more pronounced jaundice, itchy skin in the corners of the eyes appear yellow under the skin xanthoma-spots.
the diagnosis of the disease the patient is prescribed the following tests for hepatitis - biochemical blood tests, tests for liver function indicators on autoantibodies.Furthermore, prescribed abdominal ultrasound, liver biopsy, if necessary, and computerized tomography.
