Immunological response and oesophageal varices in PBC

Area of Science:

• Hepatology
• Gastroenterology
• Immunology

Background:

• Primary biliary cholangitis (PBC) is a chronic liver disease with potential complications like esophageal varices.
• Esophageal varices represent a significant risk factor for morbidity and mortality in PBC patients.
• Understanding the prognostic implications of varices and associated factors is vital for patient management.

Purpose of the Study:

• To investigate the clinical features of PBC, focusing on esophageal varices.
• To evaluate the prognostic impact of esophageal varices and high-risk varices on survival rates in PBC patients.
• To assess the effectiveness of different therapeutic approaches and identify key prognostic markers.

Main Methods:

• Retrospective analysis of clinical data from 93 PBC patients.
• Evaluation of survival rates based on symptomatic status, presence of esophageal varices (including high-risk), and treatment strategies.
• Assessment of antimitochondrial antibody (antiM8) status and serum alkaline phosphatase levels as prognostic indicators.

Main Results:

• Five-year survival rates were 88.7% for asymptomatic PBC and 43.7% for symptomatic PBC.
• Patients with esophageal varices had a 5-year survival rate of 44.0% compared to 68.8% without varices.
• High-risk varices were associated with a 5-year survival of 39.1%, significantly lower than those without (67.9%).
• Prophylactic therapy showed better prognostic outcomes than emergency or elective therapy for variceal bleeding.
• AntiM8 positive patients exhibited a poorer prognosis than antiM8 negative patients.

Conclusions:

• Esophageal varices, particularly high-risk varices, are associated with significantly reduced survival in PBC patients.
• Prophylactic management of varices and close monitoring of high-risk individuals are essential.
• Elevated serum alkaline phosphatase and antiM8 positivity are indicators of poor prognosis, warranting closer attention.
