Study Notes
Hepatitis Overview
- Hepatitis is liver inflammation, potentially impairing liver function.
- Types: acute (<6 months) or chronic (>6 months).
- Causes: various infectious viruses and non-infectious agents.
- Five main viral types: A, B, C, D, E.
Viral Hepatitis Etiology
Hepatitis A Virus (HAV)
- Transmission: fecal-oral route, poor sanitation.
- Risk factors: travel to endemic areas, close contact, contaminated food/water.
- Pathogenesis: infects hepatocytes, replicates, causes cell damage. Self-limiting, usually doesn't become chronic.
Hepatitis B Virus (HBV)
- Transmission: bloodborne, sexual, perinatal.
- Risk factors: unprotected sex, needle sharing, birth from infected mother, healthcare exposure.
- Pathogenesis: DNA virus, integrates into host genome; chronic infection possible due to immune tolerance.
Hepatitis C Virus (HCV)
- Transmission: bloodborne, IV drug use, blood transfusions.
- Risk factors: needle sharing, pre-1992 blood products, unsterilized equipment, tattoos/piercings.
- Pathogenesis: RNA virus, high mutation rate, evades immune response; chronic leading to fibrosis and cirrhosis.
Hepatitis D Virus (HDV)
- Transmission: bloodborne, requires concurrent HBV infection for replication.
- Risk factors: HBV co-infection, IV drug use, blood transfusions.
Hepatitis E Virus (HEV)
- Transmission: fecal-oral, common in developing countries, severe in pregnant women.
- Risk factors: contaminated water, undercooked meat, zoonotic transmission
Non-Viral Hepatitis Etiology
- Alcohol: chronic consumption leads to alcoholic hepatitis.
- Drugs/toxins: acetaminophen overdose, certain antibiotics, herbal supplements.
- Autoimmune disease: autoimmune hepatitis (body attacks liver cells).
Clinical Manifestations
Acute Hepatitis
- Pre-icteric phase: flu-like symptoms (anorexia, nausea, vomiting, fatigue, abdominal pain).
- Icteric phase: jaundice, dark urine, pale stools, hepatomegaly, pruritus.
Chronic Hepatitis
- Often asymptomatic until advanced stages. Symptoms include: fatigue, right upper quadrant pain, joint pain, and jaundice.
Other Manifestations
- HBV: aplastic anemia, glomerulonephritis, vasculitis
- HCV: mixed cryoglobulinemia, increased risk B-cell lymphoma, ITP, autoimmune hemolytic anemia, glomerulonephritis, vasculitis, porphyria cutanea tarda, lichen planus, increased risk diabetes, thyroiditis.
Complications
- Fulminant Hepatitis: rapid liver failure, encephalopathy, coagulopathy, high mortality.
- Cirrhosis: chronic liver damage, fibrosis, portal hypertension, variceal bleeding, ascites.
- Hepatocellular Carcinoma (HCC): increased risk with chronic HBV and HCV infections (often advanced, poor prognosis).
Diagnosis
- Liver function tests (LFTs): elevated aminotransferases (ALT, AST).
- Elevated bilirubin, abnormal alkaline phosphatase, GGT.
- Serological tests (specific for each virus type): IgM/IgG antibodies, antigens.
Treatment
- General: supportive care (rest, diet, hydration). Avoid alcohol/hepatotoxic drugs.
- Specific: varies by virus type (antivirals, direct-acting antivirals).
Managing Complications
- Cirrhosis: monitor for varices, manage ascites, prevent encephalopathy, liver transplant.
- HCC: surgical resection, liver transplant, ablation, chemoembolization, systemic therapies.
Prevention
- General: hygiene, safe food/water consumption.
- Safe practices: condoms, needle exchange, safe injection practices in healthcare settings.
- Vaccines for HAV and HBV (routine childhood immunization).
