Natural History
Of every 100 people infected with the Hepatitis C virus, about
- 75–85 people will develop chronic Hepatitis C virus infection; of those,
- 60–70 people will go on to develop chronic liver disease
- 5–20 people will go on to develop cirrhosis over a period of 20–30 years
- 1–5 people will die from cirrhosis or liver cancer
Complications
- Hepatitis C infection can continue over many years leading to chronic hepatitis
- Over years, liver may undergo extensive damage and scarring resulting in cirrhosis
- Liver failure
- Hepatocellular carcinoma may occur in patients with chronic hepatitis C infection.[1]
In diagnosis of cirrhosis (Ishak scores, 5-6) in patients with hepatitis C, the aspartate aminotransferase to platelet ratio index (APRI) ratio > 1 suggests cirrhosis with accuracy of:[2]
- Sensitivity = 79%
- Specificity = 78%
Prognosis
- Acute Infection
- 20% recover
- 80% have persistent infection
- 30% of these patients develop cirrhosis
- Genotype
- Predicts response to treatment
- Genotype 1 less responsive than types 2 & 3
