Hepatitis B - Screening, Prevention, Diagnosis & Treatment

Living in the 21st century, it’s common to take health for granted. But with today’s increase in global travel and close contact between cultures, there is an increasing risk of potentially life-threatening diseases – including Hepatitis B. Unfortunately, this virus can be silent yet highly damaging if left without diagnosis or treatment.

So, how do we recognize signs of possible infection? How can we protect ourselves from coming into contact with the virus and what solution is available should that happen? Making sure you get tested or vaccinated against this virus is key to avoiding an unexpected diagnosis further down the line. In this blog post, we will dive into everything there is to know about Hepatitis B – from screening and prevention measures diagnosing procedures to treatment options – so you can protect your own well-being or those of your loved ones.

Hepatitis B

The hepatitis B virus (HBV), which can be acute or chronic, is the cause of hepatitis B. Serious risks from chronic hepatitis B include liver cancer and cirrhosis. Because symptoms might not show up right away, screening becomes essential. Knowing Hepatitis B Immunization is also important.

Who Should Get Screened In Hepatitis?

High-Risk Individuals

  • People with a history of unprotected sex with multiple partners.
  • Individuals who have shared needles during drug use.
  • Healthcare workers exposed to blood.
  • Infants born to mothers with hepatitis B.

Routine Screenings

  • Many countries include hepatitis B screening as part of regular blood tests during pregnancy and at birth.

Screening Tests for Hepatitis B

Hepatitis B Surface Antigen (HBsAg): This blood test detects the presence of the HBV surface antigen, indicating an active infection.

Antibody Tests:

  • Anti-HBs (Hepatitis B Surface Antibody): Detects antibodies in individuals previously vaccinated or those who have recovered from a past illness.
  • Anti-HBc (Hepatitis B Core Antibody): Indicates past or present condition.
  • Hepatitis B e Antigen (HBeAg):Presence may indicate a higher risk of transmitting the virus to others.

Importance of Early Detection

  • Preventing Transmission: Identifying infected individuals helps prevent the spread of the virus to others.
  • Timely Intervention: Early diagnosis allows for appropriate medical intervention and management.
  • Preventing Complications: Monitoring individuals with chronic hepatitis B helps prevent complications such as cirrhosis and liver cancer.
  • Blood Test: To look for HBV antigens and antibodies, a straightforward blood test is performed.
  • Preparation: Generally, no extra planning is needed. Let your doctor know if you take any vitamins or prescription drugs.
  • Once the Screening, Counselling: In the case that test results are favourable, medical professionals provide counselling regarding next steps, possible courses of action, and preventative measures.
  • Vaccinating against hepatitis B is an essential preventive step, particularly for those who are high-risk.

Hepatitis B Symptoms

Here's a closer look at the potential symptoms associated with Hepatitis B:

Early Symptoms: The Silent Invader

Fatigue:

  • Persistent and unexplained fatigue is a common early symptom.
  • Individuals may feel excessively tired, even after adequate rest.

Muscle and Joint Pain:

  • Generalized muscle and joint discomfort can occur.
  • This symptom is often mistaken for the effects of strenuous activities.

Loss of Appetite:

  • A sudden decrease in appetite may manifest.
  • Individuals may need help to eat as usual.

Mild Fever:

  • Low-grade fever or elevated body temperature might be present.
  • This is the body's response to the viral infection.

Gastrointestinal Distress: The Liver's Cry for Help

Nausea and Vomiting:

  • Some individuals may experience nausea, potentially leading to vomiting.
  • These symptoms can contribute to dehydration.

Abdominal Pain:

  • Discomfort or pain in the upper right side of the abdomen may occur.
  • This is associated with liver inflammation.

Dark Urine:

  • Urine may appear dark or tea-coloured due to increased bilirubin levels.
  • Bilirubin is a yellow pigment produced during the breakdown of red blood cells.

Pale Stools:

  • Stools may become pale or clay-coloured.
  • This change is related to the absence of normal bile flow.

Jaundice: A Tell-tale Sign of Liver Involvement

Jaundice:

  • One of the hallmark symptoms of Hepatitis B is jaundice.
  • Yellowing occurs due to the build-up of bilirubin in the bloodstream.

Chronic Infection: Lingering Challenges

  • In cases of chronic Hepatitis B, fatigue may persist over an extended period.
  • This can significantly impact daily activities.

Liver Cancer:

  • Liver cancer risk is increased by chronic Hepatitis B. Abdominal pain and unexplained weight loss are some symptoms.

Seeking Medical Attention: When to Act

See a doctor right once if you encounter any symptoms, especially if you are aware that you have been exposed to hepatitis B:

  • Jaundice
  • Severe abdominal pain or persistent vomiting.
  • Confusion or difficulty staying awake.
  • Signs of dehydration, such as excessive thirst and dark urine.

Hepatitis B Prevention: Safeguarding Your Health

Let's explore the critical aspects of Hepatitis B prevention.

Simple measures to help halt the spread of hepatitis B, in addition to vaccination:

  • After any potential blood exposure, properly wash your hands with soap and water.
  • Condoms should be used with sexual partners.
  • Avoid coming into direct touch with blood or bodily fluids.
  • Blood spills should be cleaned up with a new diluted bleach solution (one part bleach to nine parts water).
  • Cover all cuts well.
  • Avoid using unlawful street drugs (for example, injecting, inhaling, snorting, or popping pills).
  • For ear or body piercing, tattoos, and acupuncture, use only new, sterilized needles.

Vaccination: The Foundation of Prevention

Vaccination for High-Risk Groups:

  • Healthcare workers and individuals with specific risk factors, such as multiple sexual partners or injection drug use, are strongly advised to get vaccinated.

Birth Dose for Newborns:

  • Administering the first hepatitis B vaccine to newborns within 24 hours of birth is a crucial preventive measure.
  • This helps prevent mother-to-child transmission, a standard mode of infection.

Preventing Mother-to-Child Transmission:

  • Mothers with hepatitis B are tested during pregnancy to determine the risk of transmission.
  • Administering hepatitis B immune globulin (HBIG) and the vaccine to the newborn within 12 hours of birth significantly reduces the risk.

Safe Practices

Safe Sex:

  • Practising safe sex, including the use of condoms, reduces the risk of sexual transmission.

Safe Injection Practices:

  • Avoid sharing needles or other drug paraphernalia to prevent the spread of the virus through contaminated blood.

Testing and Screening

  • Regular screening for hepatitis B is crucial, especially for individuals at higher risk.
  • Testing allows early detection and timely intervention to prevent complications and further transmission.

Healthcare Worker Precautions:

  • Healthcare workers should adhere to strict infection control measures to prevent occupational exposure.
  • This includes proper handling of needles and other sharp instruments and following universal precautions.

Education and Awareness:

  • Raising awareness about hepatitis B and its modes of transmission is essential.
  • Education empowers individuals to take preventive measures and seek hepatitis b vaccination when necessary.

Hepatitis B Diagnosis and Treatment

Let's discuss Hepatitis B diagnosis and treatment:

Diagnosis of Hepatitis B

  • Blood Tests: The presence of hepatitis B surface antigen (HBsAg) indicates an active infection.
  • Anti-HBc Test: Detects antibodies against the hepatitis B core antigen, indicating current or past conditions.
  • Liver Function Tests: Assess the liver's health by measuring enzyme levels.
  • Viral Load Testing: Quantifies the amount of virus in the blood, guiding treatment decisions.
  • HBeAg Test: Identifies a marker associated with high viral replication and increased infectivity.
  • Liver Biopsy or Imaging: Provides detailed information about liver health and the extent of damage.
  • FibroScan: Non-invasive method to assess liver stiffness, aiding in the fibrosis evaluation.

Hepatitis B Treatment Strategies: Navigating the Path to Wellness

  • Nucleoside/Nucleotide Analogues (NAs): Drugs like entecavir and tenofovir reduce viral replication. Prescribed based on the patient's health status and viral load.
  • Interferons: Stimulate the immune system to fight the virus. Limited use due to side effects.
  • Liver Health Management: Ongoing assessment of liver function and viral load. Ensures protection against other hepatitis B strains.
  • Lifestyle Modifications: Alcohol can exacerbate liver damage; abstinence is advisable. A balanced diet supports overall health, especially liver function.
  • Management of Complications: Regular assessment for liver cirrhosis and related complications. Individuals with cirrhosis are monitored for HCC.

Patient Education and Support: Empowering Wellness

  • Educating Patients: Providing information about Hepatitis B, its transmission, and management.
  • Support Groups: Connecting patients with support networks for shared experiences.
  • Medication Management: Ensuring patients understand and adhere to prescribed antiviral regimens.
  • Health Monitoring: Scheduled check-ups to evaluate treatment efficacy and liver health.
  • Vaccination for Contacts: Encouraging vaccination for household members and close contacts.
