Hepatitis D (HDV)
A Severe Co-Infection That Accelerates Liver Damage
Hepatitis D is a viral infection that occurs only in individuals already infected with Hepatitis B. It can significantly accelerate liver damage, leading to rapid progression to cirrhosis and liver failure.

HDV Requires HBV Co-Infection

HBV vaccination prevents HDV. Early HBV treatment reduces risk of HDV superinfection.
What is Hepatitis D?
Hepatitis D Virus (HDV) is a defective virus that can only infect individuals who already have Hepatitis B.
It occurs in two forms:
- Co-infection: HBV and HDV acquired together
- Superinfection: HDV infects someone already with chronic HBV
HDV causes:
- Severe liver inflammation
- Rapid progression to cirrhosis
- Increased risk of liver failure
Early Signs & Symptoms
Rapid symptom progression → Early evaluation required
Fatigue
Jaundice
Abdominal discomfort
Loss of appetite
How HDV Spreads & Risk Factors
How HDV Spreads
- Blood contact
- Needle sharing
- Unsterile procedures
- (Same transmission routes as HBV)
Risk Factors
- Existing Hepatitis B infection
- High-risk exposure to blood
- Lack of HBV vaccination
Disease Progression
Co-infection
HBV + HDV acquired together
May resolve
Superinfection
HDV in chronic HBV patient
Severe chronic disease
Rapid liver damage
Cirrhosis
Advanced liver scarring
End Stage Liver Disease
Liver failure
Transplant required
Diagnosis & Tests
Anti-HDV antibody
HDV RNA (viral load)
HBV markers (HBsAg, HBV DNA)
Liver function tests (LFT)
Fibroscan / Ultrasound
Check Your Liver Status
Understand your HBV + HDV risk
Treatment Options (Before Transplant)
1. Antiviral Therapy
- Limited effectiveness
2. Manage HBV Infection
- HBV suppression is critical
3. Monitoring
- Liver function
- Disease progression
4. Manage Complications
- Cirrhosis care
When is Liver Transplant Needed?
Decompensated cirrhosis develops
Liver function declines rapidly
Liver failure occurs
Hepatitis D Requires Early Detection
Timely diagnosis can prevent rapid progression
Important: Prevention via HBV Control
HDV occurs only with HBV • HBV vaccination prevents HDV • Early HBV treatment reduces risk
Medical Management vs Transplant
Medical Management
Stage: Early/Moderate • Goal: Slow progression • Outcome: Limited
Liver Transplant
Stage: Advanced • Goal: Replace liver • Outcome: Life-saving
