Insights
Antiviral therapy may improve liver disease in chronic hepatitis C patients, potentially reducing portal hypertension (PHT). Further research is needed to confirm these effects on liver fibrosis and PHT management.
Area of Science:
- Hepatology
- Gastroenterology
- Virology
Background:
- Chronic hepatitis C is a primary cause of advanced liver disease and cirrhosis globally.
- Portal hypertension (PHT) is a common complication of cirrhosis, leading to severe outcomes and liver transplantation.
- Antiviral therapy (AVT) shows potential benefits for liver inflammation and fibrosis, independent of viral clearance.
Purpose of the Study:
- To review the impact of AVT on portal hypertension (PHT) in advanced chronic hepatitis C.
- To explore the implications of AVT-induced histological changes on PHT.
- To discuss clinical practice and future research directions regarding AVT and PHT.
Main Methods:
- Literature review of studies investigating AVT in chronic hepatitis C patients with advanced liver disease.
- Analysis of data on histological changes, liver inflammation, fibrosis, and portal hypertension.
- Synthesis of findings on the relationship between AVT, histological improvements, and PHT.
Main Results:
- AVT may exert beneficial effects on liver histology, including inflammation and fibrosis.
- The influence of these histological changes on portal hypertension (PHT) is under investigation.
- Evidence suggests a potential, albeit not fully elucidated, impact of AVT on PHT.
Conclusions:
- AVT may offer benefits beyond viral eradication, potentially impacting PHT in chronic hepatitis C.
- Further research is crucial to understand the mechanisms and clinical significance of AVT's effect on PHT.
- Investigating AVT's role in managing PHT could refine treatment strategies for advanced liver disease.
Abstract:
Chronic hepatitis C is the leading cause of advanced liver disease in the Western world. Most patients with liver cirrhosis develop portal hypertension (PHT) (i.e. an abnormal gradient between portal and inferior vena cava pressures), responsible for the most frequent and severe complications of liver disease and, as a consequence, the main cause of death and liver transplantation in those patients. The existence of a potential beneficial effect of antiviral therapy (AVT) on liver inflammation and fibrosis, partially independent of the degree of virological response, has been recently reported. However, the possible influence of these histological changes on PHT has not been evaluated. In this article, we summarize the available findings regarding the effect of AVT on PHT in patients with advanced chronic hepatitis C, as well as its possible implications for clinical practice and future avenues of investigation.
