This name has its roots in Australia, where such a cell was first discovered. The Australian antigen is better known to us as the hepatitis B virus or as serum hepatitis.
The disease can occur in two forms:
- acute;
- chronic.
A lot in successful therapy depends on how quickly the patient sought help from a doctor and how early appropriate treatment was started. What this “Australian antigen” is, where and how it is infected will be discussed below.
Situations conducive to infectionA very small number of cells is enough for pathology to successfully develop in the body. Typically, the Australian antigen from the carrier enters the healthy body as follows:
- through donated blood;
- by reusing one syringe by several people;
- sexually;
- from mother to child.
The latter, vertical type of infection, is rare. But transmission of the virus to the child from the mother is one hundred percent when HIV infection occurs, and hepatitis B in the acute stage coincides with the last months of pregnancy.
The Australian antigen is transmitted both during tattooing and when visiting the dentist, ear piercing, and other similar procedures. But in half of the cases, the method of infection still remains unknown.
Course of the diseaseIf we talk about what the Australian antigen is, it should be noted that the pathology begins to manifest itself only after a few months. It begins with symptoms similar to influenza or ARVI:
- temperature increase;
- weakness;
- headache;
- sometimes - a rash.
Later jaundice is added and the picture begins to change:
- no appetite;
- vomiting and nausea appear;
- pain in the right hypochondrium;
- urine becomes dark, and feces, on the contrary, become light.
First of all, information is obtained from the patient about possible blood transfusions in the past, surgical interventions, and casual sexual relations. The patient is also subjected to several blood tests, including:
- identification of specific markers, namely positive Australian antigen;
- changes in blood parameters for biochemical processes - liver enzymes, and others.
Treatment of the disease when the Australian antigen is detected
Treatment of acute forms of the disease differs from treatment of chronic ones. So, in order to get rid of hepatitis B in its acute form, drugs are prescribed to restore liver tissue and maintenance therapy. Much attention is paid to detoxifying the body.
When the chronic form occurs, the doctor selects an individual complex depending on the age and general health of the patient. For this use:
- alpha interferons;
- nucleosides and their analogues;
- immunostimulants.
The chronic form of the pathology is subject to therapy for about six months. After this time, repeat tests are prescribed. The indicator of recovery is 
normal bilirubin and absence of Australian antigen in the blood.
If a repeat test again indicates the disease, therapy should be repeated. About a third of hepatitis B cases are cured within six months. The remaining patients are sent for re-treatment, although the decrease in virus and bilirubin levels already indicates positive dynamics.
Often a complete cure never occurs, but careful adherence to the diet and all the doctor’s recommendations guarantees a favorable course of the pathology. In this case, it is important to prevent the development of liver cirrhosis and cancer in this area.
The factor indicating the presence of group B hepatitis in the human body is the Australian antigen. The pathology is a serious disease that can completely destroy the functionality of the liver. Despite its widespread prevalence, the disease is relatively difficult to overcome.
Transmission routes
Hepatitis B is one of the most dangerous types of the disease. To detect an inflammatory process in the liver area, Australian hepatitis is used, which is an antigen or, more simply, part of a viral cell.
There is a so-called risk group, which includes:
- women during pregnancy;
- workers of medical institutions;
- patients diagnosed with impaired liver function and other diseases;
- patients who require surgical treatment;
- people suffering from drug addiction;
- blood donors.
The pathological process is widespread, while most of the world's population does not have information about being a carrier of a harmful virus and a serious disease. It is possible to determine the presence of an antigen in the body using blood, seminal fluid, urine or breast milk. Diagnosing the pathology means that the patient may have hepatitis in acute or chronic form. Transmission of the virus from an infected patient occurs in several ways: the use of an unsterile syringe, blood transfusion from a person infected with the virus, the use of nail care kits or utensils, and unprotected sexual contact. Often the disease can be transmitted from a sick mother to a child during birth.
Symptoms of presence
The presence of the Australian antigen in the human body, as a rule, is not accompanied by the presence of symptomatic signs. This indicates the presence of a latent form of acute pathological process in the patient. Duration of storage is from 2.5 months to six months. Symptoms appear gradually and one at a time. The most common include:
- the occurrence of pain in the area of articular joints;
- impaired intestinal functionality, accompanied by diarrhea;
- the appearance of rashes on the skin.
The patient's general condition is assessed as serious. At the same time, the patient’s body temperature rises and fever is present. The stool becomes light-colored, and the urine darkens and foams. A dull pain syndrome occurs under the right rib. After a certain amount of time, the patient develops an icteric period, the upper layer of the epidermis and the membranes of the eyes acquire a yellowish tint. As the disease spreads, the general health of a carrier of the Australian antigen may deteriorate and improve spontaneously. The patient is dangerous to people around him.
The period of complication is divided into several stages, each of which is characterized by a certain set of symptomatic manifestations of the disease in the patient:
- Stage 1. It is an increase in icteric syndrome, accompanied by painful signs in the liver area. In parallel with this, the patient experiences impaired coordination of motor activity, lack of ability to navigate in space, a stable increase in heart rate, decreased duration and quality of sleep, frequent mood changes and possible aggression.
- Stage 2. It is characterized by increased intoxication of the patient's body. Consciousness becomes more confused. There is trembling of the upper and lower extremities, complete loss of orientation in time space. The internal organ increases in size and is almost impossible to palpate. The patient reveals the presence of swelling and the possible presence of accumulated fluid in the abdominal cavity.
- Stage 3. Represents a comatose state of the patient. When a shallow coma is detected, the carrier of the Australian antigen retains swallowing reflexes and is able to respond to strong stimuli. Spontaneous bowel and bladder emptying occurs. When a deep coma is detected, reflexes are completely suppressed, and the possibility of death cannot be ruled out.
The most dangerous is hepatic coma. The disease is diagnosed when the liver is completely destroyed and functionally impaired.
Diagnostics
To detect the disease, the patient is recommended to undergo a series of diagnostic measures, which include the need to take blood tests, undergo an ultrasound examination and evaluate clinical manifestations. The interpretation of the results obtained is carried out only by the attending physician.
The essence of a laboratory test of a patient's blood is the reaction of the antibody to the antigen. Specialists combine the patient’s blood with the reagent. Upon entering the reaction, a positive conclusion is made, indicating the presence of hepatitis disease in the body. This technique makes it possible to determine the presence of pathology in the early stages, including during the incubation period.
Medical science knows the so-called express method. It allows you to detect the presence of the Australian antigen in an infectious patient. The procedure can be carried out at home, but a test collection kit can be purchased at a pharmacy. It includes a scarifier, a test strip and a container for a special solution. The procedure for taking material requires the patient to comply with a clearly established sequence:
- treating the finger of the upper limb and puncturing it with a scarifier;
- applying a small amount of blood to the indicator;
- placing the strip in a container with liquid to be tested.
The reaction continues for a quarter of an hour. After this, you are allowed to review the results obtained. The presence of 1 band indicates a negative reaction, 2 – a positive one. If the presence of the disease is confirmed, the patient must immediately consult a doctor for further examination.
A serological study is considered no less informative. The procedure involves the use of blood serum followed by study using special laboratory equipment. Ultrasound examination helps to identify changes in the patient’s liver, but this is not possible at all stages of the development of the pathological process.
The structure of the results includes various characteristics. In addition to a positive or negative conclusion, it is possible to obtain false data regarding the disease. They arise due to the influence of several factors: poor quality of reagents, poor functionality of equipment, erroneous actions of laboratory workers. To confirm the findings, it is recommended to confirm them using additional diagnostic options. A false negative result is considered the most unpleasant for the patient. In this situation, the virus is present in the human body and is in the active stage, but is not detected. This is acceptable when diagnosing in the early stages of pathology development, the presence of a small amount of antigen concentration, the detection of a virus of rare and little-studied etymology, the course of the disease in a latent form and the insufficient activity of the human immune system.
If necessary, the patient has the right to retake the blood test later or go to another medical institution; moreover, modern reagents and equipment make it possible to detect the presence of the virus even in a latent form. To obtain recommendations regarding subsequent diagnosis and therapy, the patient should contact an infectious disease specialist.
Therapy methods
Therapeutic measures require the use of a variety of therapy methods. At the initial stages of the development of the disease, the body has the ability to independently overcome the pathological process, so it is not necessary to treat it with medications.
If the patient does not have any complications, elimination of the virus occurs after several months. In this case, auxiliary treatment methods are used. The patient must review his diet. It is recommended to exclude drinks containing alcohol, fatty meats and fish, preservatives and marinades.
If progression of the disease is detected, the patient is prescribed therapy aimed at maintaining liver function. Treatment involves cleansing the internal organ of existing harmful substances. Therapy involves the use of droppers with liquid components. To remove toxins and maintain functionality, hepatoprotectors are prescribed to help prevent liver destruction. At the same time, it is necessary to use vitamin complexes to stabilize the functioning of the entire human body.
When a patient is diagnosed with a chronic form of the disease, drug therapy is prescribed: antiviral drugs. The patient is advised to rest throughout the entire treatment, which can last for one year.
Prevention
Disease prevention measures are aimed at ensuring that the patient can avoid infection. To achieve this, the following mandatory rules are formulated:
- Conducting a complete analysis of blood donors immediately before blood donation. A patient who has suffered a pathology or is at the stage of the incubation period is not allowed to donate blood.
- Mandatory sterilization of medical equipment, especially those intended for reusable use. If possible, medical instruments are also processed.
- A person’s compliance with personal hygiene rules, avoiding frequent changes of sexual partners and unprotected sexual contact.
Prevention of patients in childhood is carried out through vaccination. The vaccination is done on the first day after the birth of the child. It is mandatory to vaccinate children born to mothers who are carriers of the virus, employees and pupils of orphanages, people in contact with contaminated material, patients who require regular blood transfusions and specialists working in research laboratories.
Possible complications
It is not difficult to detect the presence of a disease in a patient’s body. However, pathology is not always detected in a timely manner due to the lack of visible symptomatic manifestations. The patient may not suspect for a long time that there are any problems in his body.
After the virus molecules appear in the liver area, they immediately begin to penetrate the blood cells. It is impossible to completely get rid of the disease, since the virus is resistant to various factors. For example, it is not subject to freezing, it is not destroyed when exposed to temperatures up to 60 degrees, and does not react to the influence of certain alkalis, acids and certain chemical compounds.
If the patient does not contact medical specialists in a timely manner, the chances of the occurrence of cirrhosis and carcinoma increase significantly. Gradually, the pathology turns into an oncological disease and provokes the threat of fatal consequences and the inability to restore the body.
The Australian antigen is a specific type of protein that is released in the presence of hepatitis B. Its presence in the body provides the basis for establishing a final diagnosis and subsequent therapeutic measures. Infection can be carried out in various ways, and the disease does not require special treatment. As a preventive measure, vaccination is necessary. At the moment, there is no consensus as to what becomes the main cause of infection in the body. The possibility of erroneous analysis in patients diagnosed with AIDS is allowed. If you follow all the requirements and recommendations, you can achieve a successful course of the disease.
The presence of the Australian antigen indicates infection with the hepatitis B virus. The disease can occur in acute or chronic form. A blood test for Australian antigen is prescribed when: determining hepatitis, during a medical examination, during periodic examination of people at risk ( undergoing frequent blood transfusions or intravenous injections), in preparation for surgery, for various ailments liver.
Long-term carriage of the antigen without symptoms is observed in ten percent of patients.
An antigen is detected in the blood serum of a person suffering from an acute form of hepatitis, usually in the last fifteen days of the latent phase of the disease or within one to six months after the onset symptoms. After which the antigen level gradually decreases and normally should go to zero within twelve weeks. However, most often in the acute form of the disease, the antigen is detected in the patient’s blood for no longer than six months. If after this period the antigen is detected, we can talk about the chronic course of hepatitis. If an antigen is detected in a “healthy” person, during a medical examination, additional examinations must be carried out, and if the antigen is detected within twelve weeks, the person is diagnosed diagnosis « Australian antigen carriage" After recovery, carriage develops in three percent of patients.
For analysis blood is taken from a vein. After collection, the blood is transferred into a test tube with a special substance that accelerates clotting. A piece of cotton wool soaked in alcohol is applied to the injection site. If a hematoma forms, warm lotions are prescribed.
All methods for detecting the Australian antigen are divided into three generations:
- first– precipitation reaction in the gel,
- second– reaction of counter immunoelectrophoresis, complement fixation, latex agglutination, immunoelectron microscopy,
- third– reverse passive hemagglutination reaction, enzyme immunoassay.
Third generation methods are used both in regular clinics and hospitals, and for scientific purposes. Laboratories purchase ready-made reagent kits produced by the pharmaceutical industry. The most widely used method is enzyme immunoassay, since it makes it possible to carry out a large number of examinations in a short period of time and is quite reliable.
