Hepatitis B: Symptoms, Causes & Treatment

What is Hepatitis B? 

Hepatitis B is a viral infection that leads to liver inflammation. It can manifest as a short-term illness that may be asymptomatic and resolve on its own, known as acute hepatitis B. However, some individuals may develop a chronic form of the virus, which can result in serious complications such as cirrhosis and liver failure.

While there is currently no cure for hepatitis B, there are treatments available that can render the virus inactive. An inactive hepatitis B status indicates that the virus is present but cannot be transmitted to others.

What are The Different Types of Hepatitis B?

Hepatitis B virus (HBV) and can manifest in different forms depending on the duration, severity, and immune response. The infection can be acute, where the virus is present for a short period (less than six months), or chronic, where it persists and can cause long-term complications. 

1. Acute Hepatitis B develops soon after exposure, often clearing naturally in healthy adults, though some may experience symptoms such as jaundice, nausea, fever, and fatigue. 
2. Chronic Hepatitis B occurs when the virus remains in the body beyond six months, potentially leading to liver cirrhosis, liver failure, or even liver cancer. Within chronic cases, some individuals may be inactive carriers, meaning the virus is present but not actively damaging the liver, while others may have chronic active hepatitis, where HBV continues to replicate and cause inflammation. 
3. Fulminant Hepatitis B is rare but can lead to sudden liver failure, requiring urgent medical intervention or a liver transplant. 
4. Occult Hepatitis B, where the virus remains hidden in the liver but is undetectable in routine blood tests, makes diagnosis challenging. 

Managing Hepatitis B involves vaccination, regular monitoring, and antiviral medications to reduce the viral load and protect liver health. Understanding the different types of Hepatitis B is essential for early detection, effective treatment, and prevention of severe complications.

What are its Symptoms?

Symptoms of acute hepatitis B can vary in severity, ranging from mild to severe. Typically, these symptoms manifest approximately 1 to 4 months following infection with the hepatitis B virus (HBV), although they may appear as soon as two weeks post-infection. It is important to note that some individuals, particularly young children, may remain asymptomatic despite having acute or chronic hepatitis B.

Common symptoms associated with hepatitis B include:

• Abdominal pain
• Dark-colored urine
• Fever
• Joint discomfort
• Decreased appetite
• Nausea and vomiting
• General weakness and fatigue
• Jaundice, is characterized by a yellowing of the skin and the whites of the eyes, which may be more or less noticeable depending on an individual’s skin tone.

What Causes Hepatitis B?

Hepatitis B is a viral infection caused by the hepatitis B virus. Transmission can occur through contact with infected blood and other bodily fluids in various scenarios, including:

• Sharing needles and other equipment used for injecting drugs
• Sharing personal items such as razors, toothbrushes, or nail clippers
• Engaging in sexual activities, whether heterosexual or homosexual
• Receiving tattoos with unsterilized needles and equipment
• Close familial contact with an individual who has hepatitis B
• Being born to a mother infected with hepatitis B, although this is rare in Australia due to routine screening and treatment of pregnant women, along with vaccination of newborns shortly after birth
• Accidental exposure, such as through needlestick injuries or splashes of infected blood or bodily fluids

It is important to note that hepatitis B cannot be transmitted through casual contact, such as coughing or sneezing, or contaminated food and beverages. The virus is not present in saliva, breast milk, or tears.

How is Hepatitis Diagnosed?

A diagnosis of hepatitis B infection is established through:

1. Blood tests: They are essential for identifying the presence of the hepatitis B virus in your system. They can also inform your healthcare provider whether the infection is in its acute or chronic stage. Additionally, a straightforward blood test can determine if you have immunity to the virus.  
2. Liver ultrasound: A specialized ultrasound technique known as transient elastography can assess the extent of liver damage.  
3. Liver biopsy: Your healthcare provider may perform a liver biopsy, which involves extracting a small tissue sample from your liver for analysis to evaluate any damage. This procedure entails the insertion of a thin needle through the skin into the liver to obtain the sample for laboratory examination.

Many individuals may remain asymptomatic upon contracting hepatitis B, which can lead to undiagnosed cases. Therefore, screening for hepatitis B is advised for specific groups, including:

• Individuals at increased risk.
• Those who have a history of injecting drugs.
• Males who engage in sexual activity with other males.
• Individuals born in regions where hepatitis B is prevalent.
• Aboriginal and Torres Strait Islander populations.
• Patients preparing for chemotherapy or other treatments that may weaken the immune system Individuals living with HIV or hepatitis C.
• Pregnant women.

If you suspect you have been exposed to infected blood or bodily fluids, it is crucial to consult a healthcare professional promptly. There are treatments available that can significantly lower the risk of developing the infection if administered shortly after exposure.

How is Hepatitis Treated?

There is currently no specific treatment available for acute hepatitis B infection. The focus of treatment is on maintaining overall health rather than curing the condition.

Not all individuals with chronic hepatitis B require treatment. Generally, those with chronic hepatitis B who show no signs of liver damage do not need intervention. However, it is crucial to have regular medical evaluations to monitor for any indications of liver damage.

Management of acute hepatitis B

In most cases, specific treatment for acute hepatitis B is unnecessary, as adults typically recover without intervention. If you experience severe symptoms, your healthcare provider may recommend the following supportive measures:

• Pain relief medications
• Intravenous fluids
• Intravenous nutrition.

Management of chronic hepatitis B

Whether treatment is necessary for chronic hepatitis B depends on individual circumstances. Your healthcare provider will likely recommend treatment only if there are indications of liver disease, as the medications tend to be most effective in these cases. While they do not provide a cure, these treatments can enhance your immune response, slowing the replication of the virus and helping to protect your liver from damage.

Your healthcare provider may recommend one or more of the following treatments:

Oral antiviral medications: These are considered the most effective at reducing the rate of viral replication. Depending on your specific health circumstances and your response to treatment, you may be prescribed a single medication or a combination of several. Typically, these medications will need to be taken for the duration of your life.

• Interferon injections: These are man-made versions of the antibodies produced by your body to combat infections. You will usually receive several injections over a period of 6 to 12 months. This treatment is commonly recommended for children diagnosed with chronic hepatitis B.
• Liver surgery or transplantation: This option may be necessary if you have experienced significant liver damage, such as cirrhosis, liver failure, or liver cancer due to an HBV infection. If there is sufficient healthy liver tissue remaining, you may only require the removal of the damaged section. However, if the damage is extensive, a liver transplant may be necessary, where a surgeon replaces your damaged liver with a healthy one from a donor.

Recommended lifestyle modifications for individuals with chronic hepatitis B

Regardless of whether you are on medication, your healthcare provider will likely suggest several lifestyle changes to help safeguard your liver, including:

• Refraining from alcohol consumption.
• Maintaining a nutritious and balanced diet.
• Limiting your intake of fats and sugars.

Consult with your doctor before using any other medications, herbal remedies, or supplements, as some may be harmful to your liver.

Bottom Line

Hepatitis B, similar to other hepatitis viruses, can be subtle. It is possible to be infected without any noticeable symptoms. While some individuals may experience a temporary infection, hepatitis B frequently develops into a chronic condition for which there is currently no cure.
