Hepatitis B (hepatitis B) is an infectious disease that affects hundreds of millions of people worldwide, and its complexity and insidious nature are often confusing.
When many people hear a positive HBsAg test result, they often think they have been diagnosed as seriously ill and panic. However, the severity of hepatitis B is not determined by just one test result, but requires:
A comprehensive assessment is carried out based on a number of key indicators.
In fact, the diagnosis and treatment of hepatitis B is a complex and scientific process, involving the number of surface antigens, liver function, viral load, and cccDNA.
Only with a deep understanding of these aspects can patients better manage their health and alleviate their fear of disease.
A turning point in the hospital
Mr. Yuen is an ordinary office worker who has been working overtime all year round and has an irregular daily routine, and recently, he has been feeling unwell, especially in the stomach, accompanied by tiredness and loss of appetite.
With the mentality of "no big deal", Mr. Yuan never went to the hospital for examination.
Until one day, when he was told during a company physical examination that he had tested positive for hepatitis B surface antigen and the doctor told him that he needed further tests, Mr. Yuan panicked and began to worry that he might be seriously ill.
In order to find out his condition, Mr. Yuan visited a number of hospitals and finally found a professional hepatologist, Professor Zhang.
Professor Cheung told him that the severity of hepatitis B could not be determined by a single test result, and that a number of indicators needed to be taken together, and the doctor recommended that he undergo a detailed examination, including the number of hepatitis B surface antigens, liver function and related viral DNA tests.
After several weeks of examination, Mr. Yuan learned that his HBsAg level was not high, his viral load was within the acceptable range, and his liver function parameters were normal.
Although the doctor stressed the need for regular check-ups, Mr. Yuan breathed a sigh of relief and began to actively cooperate with the treatment and lifestyle adjustments, and gradually recovered his health.
Understand the severity of hepatitis B
Hepatitis B is a prevalent disease in modern medicine, but its severity is not determined solely by the results of a hepatitis B surface antigen test.
Many patients often feel uneasy after being informed of a positive result, thinking that they have been sentenced to death, but in reality, the diagnosis and evaluation of hepatitis B is a complex process that involves a comprehensive analysis of multiple indicators.
HBsAg is the outer membrane of the hepatitis B virus, and its components are mainly proteins.
Its presence is the key to the ability of hepatitis B virus to infect liver cells, and this indicator is usually detected by the five tests of hepatitis B, which is also known as the "two and a half" of hepatitis B, which is not only a preliminary screening, but also an important basis for subsequent diagnosis of the disease.
Of the five tests for hepatitis B, doctors first perform a qualitative test, which is relatively low in sensitivity and can only tell people about the presence of hepatitis B virus.
The result of a qualitative examination is a simple "positive" or "negative", which does not help much in assessing the condition.
To better understand the specifics of hepatitis B, doctors often recommend semi-quantitative tests, which are more sensitive than qualitative tests and can provide some information about how active the virus is.
However, the calculation process of semi-quantitative testing is more complex, which may lead to less intuitive results, and may be replaced by more advanced detection methods in the future.
Finally, doctors use quantitative tests to obtain a more accurate HBsAg number, a process that usually uses well-established techniques such as Abbott or Roche to obtain a specific HBsAg value in international units per milliliter (IU/ml).
This quantitative examination can not only guide the treatment plan, but also provide an important basis for the patient's health management.
By analyzing the HBsAg values, doctors are able to determine the severity of the patient's condition, and if the surface antigen values are between 300 IU/ml and 1000 IU/ml, there is about a 60% to 65% chance that the surface antigen values will be reduced to less than 300 IU/ml after treatment.
This means that patients in this range, with reasonable treatment, can effectively control the disease and achieve negative transformation.
If the patient's surface antigen value exceeds 300 IU/ml and does not drop below 300 IU/ml after 6 months of treatment, the probability of turning negative will be significantly reduced, only about 12%.
At this point, the doctor will consider whether the treatment regimen needs to be adjusted or a more in-depth examination will be done to assess the patient's health.
The detection of cccDNA is also an important indicator of the severity of hepatitis B, which is considered to be the "mother" of the hepatitis B virus in liver cells, and its presence means that the hepatitis B virus may recur.
Although testing for cccDNA is complex, it is essential for the evaluation of the condition.
By comprehensively analyzing multiple indicators such as hepatitis B surface antigen, liver function, viral load, and cccDNA, doctors can make more accurate judgments about the patient's condition and formulate a personalized treatment plan.
A comprehensive guide from transmission routes to health management
Hepatitis B (hepatitis B) is a contagious disease caused by the hepatitis B virus (HBV).
Although the detection and management of hepatitis B has come a long way in the medical community, many people still have many misconceptions about it, and in order to better cope with it, here is important medical knowledge and scientific information about hepatitis B.
The hepatitis B virus is mainly transmitted through blood, semen and other bodily fluids, and understanding how it spreads can help us take effective preventive measures.
Mother-to-child transmission is an important route, and if a pregnant woman carries HBV, the virus may be transmitted to the newborn at birth, making prenatal and postnatal surveillance particularly important.
Sexual contact is also a common mode of transmission, especially when engaging in unprotected sex with an infected person, the risk increases dramatically, and it is important to maintain safe sexual habits.
Needle sharing is also highly susceptible to the spread of the virus, especially among drug users, which greatly increases the chance of infection.
Understanding these transmission routes can help people better protect themselves and take appropriate precautions to reduce the risk of transmission of hepatitis B.
After hepatitis B infection, patients may have a wide range of symptoms, with some people experiencing significant symptoms while others may not experience any discomfort at all.
Common symptoms of acute hepatitis B include loss of appetite, fatigue, nausea, vomiting and jaundice, which causes yellowing of the skin and eyes, and can turn into chronic hepatitis B if left untreated.
People with chronic hepatitis B often have no obvious symptoms in the early stages, but that doesn't mean their health isn't affected.
Chronic hepatitis B can lead to persistent damage to the liver, eventually leading to more serious health problems such as cirrhosis or liver cancer, and prompt detection and treatment are essential to manage the progression of the disease.
In order to determine the severity and progression of hepatitis B, regular testing is essential to provide a comprehensive assessment of a patient's health and provide an important basis for doctors to plan treatment.
The five tests for hepatitis B are the core items, which mainly measure hepatitis B surface antigen, antibodies and viral DNA to understand the presence and activity of the virus.
Liver function tests can monitor the health of the liver, specifically by checking aminotransferase levels to assess liver damage.
Viral load testing is used to determine the amount of hepatitis B virus in the blood, which is critical for assessing viral activity and response to treatment.
The cccDNA test provides information about the survival of hepatitis B virus in liver cells, and these comprehensive tests can help doctors fully evaluate the condition and then formulate a reasonable and effective treatment plan.
At present, the treatment of hepatitis B is mainly divided into antiviral therapy and interferon therapy.
Antiviral drugs, such as lamivudine, adefovir and tenofovir, are common options and can effectively inhibit the replication of the hepatitis B virus and help patients manage the disease.
On the other hand, interferon therapy acts as an immunomodulator to remove the hepatitis B virus from the body by activating the patient's immune system.
Both treatments have their own characteristics, and patients need to have regular follow-up check-ups during treatment to adjust the medication regimen according to the doctor's recommendations to ensure that the treatment is effective.
In addition to medication, health management is also an integral part, a balanced diet is the foundation, patients should try to avoid greasy and irritating foods, and increase the intake of fresh fruits and vegetables to help the body recover.
Moderate exercise can help maintain a good weight and good health, improve immunity, and regular work and rest are also crucial, ensuring adequate sleep, and avoiding staying up late and overexerting yourself can all help improve your overall health and better cope with the challenges posed by hepatitis B.
The most effective way to prevent hepatitis B is to get vaccinated, which can effectively reduce the risk of infection, especially for high-risk groups such as health workers and newborns, and maintaining good hygiene, avoiding needle sharing, and protective sex are also important ways to prevent hepatitis B.
People with hepatitis B may face psychological stress and social discrimination in their lives, so it is important for society to understand and support them to raise public awareness of hepatitis B and eliminate prejudice, so as to help patients better accept treatment and manage their health.
epilogue
In general, the management of hepatitis B is not just a focus on a single test result, but a comprehensive and detailed health management process, by understanding the transmission route of hepatitis B virus, symptoms, testing methods, and treatment options, patients can view their health status more rationally.
Hepatitis B is not an incurable disease, with the advancement of medical technology, more and more patients have achieved a good prognosis through scientific treatment and health management, therefore, the public's awareness and understanding of hepatitis B need to be improved urgently, and it is the common responsibility of society to eliminate misunderstanding and discrimination against hepatitis B patients. #秋日生活打卡季#
