Hepatitis C

Hepatitis C is a blood-borne viral infection caused by the Hepatitis C Virus (HCV) that primarily targets hepatocytes, leading to liver inflammation. Often asymptomatic in its early stages, chronic infection can progress silently over decades, resulting in severe liver damage, cirrhosis, and hepatocellular carcinoma.

Hepatitis C is caused by the Hepatitis C Virus (HCV), an enveloped, single-stranded RNA virus of the Flaviviridae family. Transmission occurs through parenteral exposure to infected blood. Primary causes include sharing contaminated needles during injection drug use, receiving unscreened blood transfusions (primarily prior to 1992), needle-stick injuries in healthcare settings, and vertical transmission from mother to child.

HCV replicates within hepatocytes. The virus is not directly cytopathic; instead, hepatocyte injury is mediated by the host's cellular immune response. Cytotoxic T lymphocytes (CD8+) and helper T cells (CD4+) attempt to clear infected cells, inducing chronic lobular and portal inflammation. Over time, persistent inflammation activates hepatic stellate cells, leading to collagen deposition, progressive fibrosis, cirrhosis, and potential oncogenesis.

Globally, an estimated 58 million people have chronic hepatitis C. Prevalence varies widely by region, with high burdens in the Mediterranean and European regions. In the United States, it is highly prevalent among individuals born between 1945 and 1965 (baby boomers) and people who inject drugs (PWID).

• Injection or intranasal drug use (current or history)
• Receiving blood transfusions or organ transplants before 1992
• Long-term hemodialysis
• Occupational exposure (accidental needle-sticks)
• HIV infection
• Perinatal exposure (infants born to HCV-positive mothers)
• Unregulated tattoos or body piercings

• Vitals: Generally normal, unless presenting with septic complications of advanced liver disease.
• Inspection: Scleral icterus, jaundice, spider angiomas, palmar erythema, muscle wasting, gynecomastia, caput medusae, and peripheral edema.
• Palpation: Hepatomegaly (early stage), micro-nodular liver border (cirrhosis), splenomegaly, and abdominal fluid wave (ascites).
• Auscultation: Normal, unless hepatic encephalopathy causes asterixis (flapping tremor observed on wrist extension).

• A. Clinical Assessment: Comprehensive history focusing on risk factors and symptoms of chronic liver disease.
• B. Laboratory Testing: Serology for HCV antibodies followed by quantitative HCV RNA PCR to confirm active infection.
• C. Imaging Studies: Right upper quadrant ultrasound and transient elastography to stage liver stiffness.
• D. Functional Tests: Assessment of synthetic liver function using PT/INR, albumin, and bilirubin levels.
• E. Biopsy Findings: Liver biopsy shows portal inflammation, interface hepatitis, and varying degrees of bridging fibrosis (Metavir stages F0-F4).
• F. Genetic Testing: HCV genotyping (Genotypes 1–6) to guide historical therapies, though less critical with modern pangenotypic regimens.
• G. Differential Diagnosis: Rule out other causes of hepatitis (alcoholic, metabolic, autoimmune, drug-induced).

Abdominal Ultrasound: Purpose: Evaluate liver parenchymal echogenicity, detect nodularity indicative of cirrhosis, and screen for hepatocellular carcinoma. Typical Findings: Increased echogenicity, nodular surface, splenomegaly, or focal lesions. Clinical Importance: Crucial for baseline screening and ongoing HCC surveillance (every 6 months in cirrhotic patients).
Transient Elastography (FibroScan): Purpose: Non-invasively measure liver stiffness to estimate the degree of fibrosis. Typical Findings:* Elevated kilopascal (kPa) scores correlated with Metavir stages F0-F

1. Clinical Importance:* Replaces liver biopsy for staging fibrosis and planning therapy.

• Hepatitis B Virus (HBV): Differentiated by positive HBsAg and positive HBV DNA.
• Alcoholic Liver Disease: History of heavy alcohol use, AST to ALT ratio > 2:1.
• Metabolic Dysfunction-Associated Steatohepatitis (MASH): Imaged-proven steatosis, metabolic syndrome features, negative HCV serologies.
• Autoimmune Hepatitis: Elevated IgG levels, positive ANA or ASMA antibodies.

• Decompensated Cirrhosis
• Hepatocellular Carcinoma (HCC)
• Portal Hypertension (leading to esophageal varices and ascites)
• Hepatic Encephalopathy
• Mixed Cryoglobulinemia Syndrome (immune-complex mediated vasculitis)
• Membranoproliferative Glomerulonephritis

The prognosis for Hepatitis C has transitioned from poor to excellent with the advent of DAAs. Achieving a Sustained Virologic Response at 12 weeks post-treatment (SVR12) equates to a virological cure in >95% of patients. Early treatment prevents progression to cirrhosis and significantly reduces, but does not entirely eliminate, the risk of hepatocellular carcinoma in patients with pre-existing advanced fibrosis.

• Avoid sharing needles, syringes, or personal items (razors, toothbrushes).
• Implementation of universal precautions in healthcare settings.
• One-time screening for all adults aged 18 and older, and regular screening for individuals with ongoing risk factors.
