What is Hepatitis?
Hepatitis is an inflammation of liver, acute or chronic. The liver is a unique organ. It is the only organ that regenerates, one can get completely regenerate itself. In other organs, e.g. heart, diseased tissue is replaced with a scar, as well as those of the skin. The liver has the capacity to replace diseased cells with new cells.
Long-term complications disease. Occur when regeneration is either incomplete, or prevented the appearance of scar tissue. This situation occurs when, aggressive agents such as viruses, medicines, alcoholic drinks etc., continue to attack the liver and prevents complete regeneration. Once scar tissue appeared reversibility of this process is very difficult to obtain. A disease characterized by the appearance in large amount of scar tissue is cirrhosis. End-stage cirrhosis is liver disease, usually followed by the appearance of complications.
Acute Hepatitis - That evolve in less than 3 months
- Viral hepatitis:
Viral Hepatitis (Hepatitis epidemic)
- Chronic hepatitis
-
chronic hepatitis b
-
chronic hepatitis c
- Hepatitis toxic drug:
-Toxic hepatitis
-Alcoholic hepatitis
- Autoimmune Hepatitis
Symptoms of Hepatitis
They are unsteady and variable intensity. Some are common to all hepatitis: jaundice, dark urine, discolored stools, nausea, liver sensitive to touch. Others are depending on the cause: in case of flu-like viral hepatitis (fatigue intense headache, curvatures and joint pain) hard and enlarged liver with signs of alcoholic impregnation (weaken skin, leg pain, tingling, etc.).
Diagnosis
Diagnosis is confirmed by blood sampling, which often shows an important increase transaminase (Liver enzymes), evidence of acute and transient destruction of liver cells, and diversion of bilirubin conjugate (product of hemoglobin by binding to albumin in the liver) and alkaline phosphates, biological evidence of jaundice. Also still looking for blood, especially blood clotting factors level, among which many are drawn up by the liver, signs of hepatocellular failure in order to assess the attractiveness of hepatitis on liver function. Blood specimens oriented study also to cause hepatitis (presence of antiviral antibodies, for example).
Evolution
Evolution is related largely because, by land and immune liver condition hepatitis had occurred before.
- Viral hepatitis spontaneously evolving favorably in most cases without squeal
- Alcoholic hepatitis can require patient transfer to intensive care when there are signs associated liver failure (bleeding from blood clotting disorders, encephalopathy), the prognosis is related mainly to stop alcohol poisoning.
- Hepatitis drug therapy regresses to stop impugned, but sometimes it happens slowly.
- Heparitele bacteria usually heal rapidly after appropriate antibiotic prescribing.
Cronic hepatitis
Hepatitis A is called chronic when it evolves over a period of more than 6 months. Sensitive cases are those of acute hepatitis. Symptoms of acute hepatitis are found more or less important (abdominal pain, jaundice, fatigue) in chronic hepatitis.
Treatment
Vary slightly depending on the cause, treatment aimed especially symptoms (analgesics, transfusions in case of digestive hemorrhage, anatomists portocava in case of portal hypertension) and balancing nutrition (management vitamins and trace elements).
Severity of chronic hepatitis is related to the time the chances of irreversible liver failure (blood coagulation disorders, hepatic encephalopathy, and metabolic acidosis) and a portal hypertension (embarrassed of blood flow in portal vein). This trend is caused by the formation of cirrhosis. Plus cirrhosis may evolve to hepatocarcinoma (liver cancer).
