5 Types of Hepatitis and Their Main Characteristics

May 09,  · The 5 types of viral hepatitis Viral infections of the liver that are classified as hepatitis include hepatitis A, B, C, D, and E. A different virus is responsible for each type of virally. Oct 29,  · To date, there are at least five different known types of viral hepatitis: A, B, C, D and E.

Hepatitis heptaitis inflammation of the liver tissue. Hepatitis A, B, and D are preventable with immunization. Worldwide inhepatitis A occurred in about million people, chronic hepatitis Heptitis affected about million people and chronic hepatitis C about million people.

Hepatitis has a broad spectrum of presentations that range from a complete lack of symptoms to severe liver failure. Both drug-induced hepatitis and autoimmune hepatitis can present what is the weather like in aruba in march similarly to acute viral hepatitis, with slight variations in symptoms depending on the bepatitis.

Fulminant hepatitis, or massive hepatic cell death how to download videos from flash players, is a rare and life-threatening complication of acute hepatitis that can occur in cases of hepatitis Heppatitis, D, and E, in addition to drug-induced and autoimmune hepatitis.

Acute cases of ttpes are seen to be resolved well within typex six-month period. When hepatitis is continued for more than six months it is termed chronic hepatitis. Causes of hepatitis can be divided into the following major categories: infectious, metabolic, ischemic, autoimmune, genetic, and other.

Infectious agents include viruses, bacteria, and parasites. Metabolic causes include prescription medications, toxins most notably alcoholand non-alcoholic fatty liver disease. Autoimmune and genetic causes of hepatitis involve genetic predispositions and tend to affect characteristic populations. Viral hepatitis is the most common type tyoes hepatitis worldwide.

Hepatitis Btne Cand hepatitis D are transmitted when blood or mucous membranes are exposed to infected blood and body fluids, such as semen and vaginal secretions. However, kissing, sharing utensils, and breastfeeding do not wat to transmission unless these fluids are introduced into open sores or cuts. Hepatitis B and C can present either acutely or chronically.

Unlike hepatitis B, most cases of hepatitis C lead to chronic infection. Parasites can also infect hepatigis liver and activate the immune response, resulting in symptoms of acute hepatitis with increased serum IgE though chronic hepatitis is possible with chronic infections.

Of the worms, the cestode Echinococcus granulosusalso known as the dog tapeworm, infects the liver and forms characteristic hepatic hydatid cysts. Bacterial infection of the liver commonly results in pyogenic liver abscessesacute hepatitis, or granulomatous or chronic liver disease.

Excessive alcohol consumption is hepatitiz significant cause of hepatitis and is the most common cause of cirrhosis in the U. This ranges in order of severity and reversibility from alcoholic steatosis least severe, most reversiblealcoholic hepatitiscirrhosis, and liver cancer most severe, least reversible.

Many chemical agents, including medications, industrial toxins, and herbal and dietary supplements, can cause hepatitis. Herbal remedies and dietary supplements are another important cause of hepatitis; these are the most common causes of drug-induced hepatitis in Korea. Exposure to other hepatotoxins can occur accidentally or intentionally through ingestion, inhalation, and skin absorption.

The industrial how to build a medieval city in minecraft carbon tetrachloride and the wild mushroom Amanita phalloides are other known hepatotoxins. Non-alcoholic hepatitis is within the spectrum of non-alcoholic liver cold sore when pregnant how to treat NALDwhich ranges in severity and reversibility from non-alcoholic fatty liver oc NAFLD to non-alcoholic steatohepatitis NASH to cirrhosis to liver cancer, similar to the spectrum of alcoholic liver disease.

Non-alcoholic liver disease occurs in people with little or no history of alcohol use, and is instead strongly associated with metabolic syndromeobesity, insulin resistance and diabetesand hypertriglyceridemia. In hepattitis early stages as with NAFLD and early NASHmost patients plants are autotrophs. what does this mean asymptomatic or have mild right upper quadrant pain, and diagnosis is suspected on the basis of abnormal liver function tests.

Autoimmune what does bd live stand for is a chronic disease typpes by an abnormal immune response against liver cells. Autoimmune hepatitis can present anywhere within the spectrum from asymptomatic to acute or chronic hepatitis to fulminant liver failure.

Many people with autoimmune hepatitis have other autoimmune diseases. However, all of how to download u tube videos diseases can lead to scarring, fibrosis, and cirrhosis of the liver. Genetic causes of hepatitis include alphaantitrypsin deficiencyhemochromatosisand Wilson's disease. When the liver is involved, alphaantitrypsin deficiency and Hepattis disease tend to present as hepatitis in the neonatal period or in childhood.

Ischemic hepatitis also known as shock liver results from reduced blood flow to the liver as in shock, heart failure, or what are the ingredients of coke zero insufficiency.

The condition usually resolves if the underlying cause is treated successfully. Ischemic hepatitis rarely causes permanent liver damage. Hepatitis can typee occur in neonates and is attributable to a variety of causes, some of which are not typically seen in adults.

The specific mechanism varies and depends on hepatotis underlying cause of the hepatitis. Generally, there is an hwat insult that causes liver injury and activation typds an inflammatory response, which can become chronic, leading to progressive fibrosis and cirrhosis. The pathway by which hepatic viruses cause viral hepatitis is best understood in the case of hepatitis B and C. Steatohepatitis is seen in both alcoholic and non-alcoholic liver disease and is the culmination of a cascade of events that began with injury.

In the case of non-alcoholic steatohepatitisthis cascade hepatitiis initiated by changes in metabolism associated with obesity, insulin heoatitis, and tge dysregulation. Diagnosis of hepatitis is made on the basis of some or all of the following: a person's signs and symptoms, medical history including sexual and substance use history, blood tests, imagingand liver biopsy.

Blood testing includes liver enzymesserology i. UltrasoundCTand MRI can all identify steatosis fatty changes of the liver tissue and nodularity of the liver surface suggestive whzt cirrhosis. In the case of hepatitis B, blood tests exist for multiple virus antigens which are different components of the virion particle and antibodies. The most apparent distinguishing factor between alcoholic steatohepatitis ASH and nonalcoholic steatohepatitis NASH is a history of excessive alcohol use.

However, in those who use alcohol, the diagnosis may just as likely be alcoholic or nonalcoholic hepatitis especially if there is concurrent obesity, diabetes, tjpes metabolic syndrome. Of note, liver biopsy shows identical findings in patients with ASH and NASH, specifically, the presence of polymorphonuclear infiltration, hepatocyte necrosis and apoptosis in the form of ballooning degenerationMallory bodiesand fibrosis around veins and sinuses.

The purpose of screening for jepatitis hepatitis is to identify people infected with the disease as early as possible, even before symptoms and transaminase elevations may be present. This allows for early treatment, which can both prevent disease progression and decrease the likelihood of transmission to others.

Hepatitis A causes an acute illness that does not progress to chronic liver disease. Therefore, the role of screening is to assess immune status in people who are at high risk of contracting the virus, as well as in people with known liver disease for whom hepatitis Hwat infection could lead to liver failure.

Those at high risk and in need of screening include: [76] [77] [78]. The presence of anti-hepatitis A IgG in the blood indicates past infection with the virus or prior vaccination.

Screening consists of a blood test that detects hepatitis B surface antigen HBsAg. If HBsAg is present, a second test — usually done on the same blood sample — that detects the antibody for the hepatitis B core antigen anti- HBcAg can differentiate between acute and chronic hepatiitis.

For people in the groups above whose exposure is ongoing, screening should be "periodic," though according to the USPSTFresearch has not defined the optimal screening interval.

Screening consists of a blood test that detects anti-hepatitis C virus antibody. The CDC recommends the hepatitis A vaccine for all children beginning at age one, as well as for those who have not been previously immunized and are at high risk for contracting the disease.

For children 12 months of age or older, the vaccination is given as a shot into the muscle in two doses 6—18 months apart and should be started before the age 24 months. If the vaccine is for hepatitis A only, two doses are given 6—18 months apart hepatitid on the manufacturer.

The CDC recommends the routine vaccination of all children under the age of 19 heptaitis the hepatitis B vaccine. Routine vaccination for hepatitis B starts with the first dose administered as a shot into the muscle before the newborn is discharged from the hospital. An additional two doses should be administered before the child is 18 months.

For babies born to a mother with hepatitis B surface antigen positivity, the first dose wht unique — in addition to the vaccine, the hepatitis what are the best motorcycle leathers globulin should also be administered, both within 12 hours of birth.

These newborns should also be regularly heepatitis for infection for at least the first year of life. There is also a combination formulation that what is marketing environment analysis both hepatitis A and B vaccines. There are currently no vaccines available in the United States for hepatitis C or E.

Because hepatitis A is transmitted primarily through the oral-fecal routethe mainstay of prevention aside from tgpes is good hygiene, access to clean water arr proper handling of sewage. As hepatitis B and C are transmitted through blood and multiple bodily fluidsprevention is aimed at screening blood prior to transfusionabstaining from the use of injection drugs, safe needle and sharps practices in healthcare settings, and safe sex practices.

The hepatitis D virus requires that a person first be infected with hepatitis B virus, so prevention efforts should focus on limiting the spread of hepatitis B. In people who have chronic hepatitis B infection and are at risk for superinfection with the hepatitis D virus, the hepstitis strategies are the same as for hepatitis B. Hepatitis E is spread primarily through the oral-fecal route but may also be spread by blood and from mother to fetus.

The mainstay of hepatitis E prevention is similar to that for hepatitis What is the oldest language namely, good hygiene and clean water practices. As excessive alcohol consumption can lead to hepatitis and cirrhosis, the following are maximal recommendations for alcohol consumption: [96].

In the United States, universal immunization has led to a two-thirds decrease in ars admissions and medical expenses due to hepatitis A. Hepatitis C infections each year had been declining since the s, but began to increase again how to get a screw out Because people with alcoholic hepatitis may have no symptoms, it can whaf difficult to diagnose and the number of oc with the disease is probably higher than many estimates.

The treatment of hepatitis varies according to the type, whether it is acute or chronic, and the severity of the disease. Hepatitis A usually does not progress helatitis a chronic state, and rarely requires hospitalization. Rarely, people with the hepatitis A virus can rapidly develop liver failure, termed fulminant hepatic failure whta, especially the elderly and those who had how do you register to vote in alaska pre-existing liver disease, especially hepatitis C.

Certain patients warrant hospitalization, especially those who present with clinical signs of ascites, peripheral edema, and hepatic encephalopathy, and laboratory signs of hypoglycemiaprolonged prothrombin timelow serum albuminand very high serum bilirubin. In these rare, more severe acute cases, patients have been successfully treated with antiviral therapy similar to that used in cases of chronic hepatitis B, with nucleoside analogues such as entecavir or tenofovir.

As there is a dearth of clinical trial data and the drugs used to treat are prone to developing resistanceexperts recommend hepatitus treatment for severe acute cases, not mild to moderate. Chronic hepatitis B management aims to control viral replication, which is correlated with progression of disease. First-line treatments currently used include PEG IFN, entecavir, and tenofovir, subject to patient and physician preference. Once it is acquired, persistence of the hepatitis C virus is the rule, resulting in chronic hepatitis C.

The goal of treatment is prevention of hepatocellular carcinoma HCC. These drugs are used in various combinations, sometimes combined with ribavirin, based on the patient's genotypedelineated as genotypes 1—6.

Hepatitis D is difficult to treat, and effective treatments are lacking. Interferon alpha has proven effective at inhibiting viral activity but only on a temporary basis. Similar to hepatitis A, treatment of hepatitis E is supportive and includes rest and ensuring adequate nutrition and hydration.

First-line treatment of alcoholic hepatitis is treatment of alcoholism. Severe alcoholic hepatitis has a poor prognosis and is notoriously difficult to treat.

Weak evidence suggests milk thistle extracts may improve survival in alcoholic what is the latest version of norton internet security disease and improve certain liver tests serum bilirubin and Whaat without causing side effects, but a firm recommendation cannot be made for or against milk thistle without further study.

Autoimmune hepatitis is commonly kf by immunosuppressants such as the corticosteroids prednisone or prednisolone, the active version of prednisolone that hepatitsi not require liver synthesis, either alone or in combination with azathioprine, and some have suggested the combination therapy is preferred to allow for lower doses of corticosteroids to reduce associated side effects, [46] although the result of treatment efficacy is comparative.
