[CLINICAL AND IMMUNOLOGICL PROFILE IN 22 PATIENTS WITH PRIMARY BILIARY CIRRHOSIS]
Summary
Primary biliary cirrhosis (PBC) in Peru presents with cholestatic patterns and jaundice. While antimitochondrial antibodies were less frequently positive, associated autoimmune diseases were common, and ursodeoxycholic acid showed limited survival benefits.
Area of Science:
- Hepatology
- Autoimmunology
- Clinical Medicine
Background:
- Primary biliary cirrhosis (PBC) is a rare autoimmune liver disease.
- Diagnosis relies on clinical, biochemical, and histopathological findings, including autoantibodies.
- Clinical variants like Overlap Syndrome exist, sometimes with negative antimitochondrial antibodies.
Purpose of the Study:
- To report the clinical, biochemical, and immunological findings of PBC patients in Lima, Peru.
- To analyze the prevalence of autoantibodies and associated autoimmune diseases.
- To evaluate the impact of ursodeoxycholic acid treatment.
Main Methods:
- Retrospective analysis of 22 patients diagnosed with PBC between 1994 and 1999.
- Clinical, biochemical (liver function tests, lipid profile), and immunological (autoantibodies) data were collected.
- Histopathological data and treatment outcomes were reviewed.
Main Results:
- 100% showed a cholestatic pattern; 95% had jaundice, 86% pruritus.
- Elevated alkaline phosphatase and transaminases were universal; hypercholesterolemia in 89%.
- Antimitochondrial antibodies (AMA) positive in 64%, antinuclear in 32%, anti-smooth muscle in 18%; 7 patients had associated autoimmune diseases.
Conclusions:
- Peruvian PBC patients exhibit a cholestatic pattern with jaundice and lower AMA positivity than reported elsewhere.
- Associated autoimmune diseases are frequent, including overlap with autoimmune hepatitis.
- Ursodeoxycholic acid improved biochemical parameters but did not significantly improve survival in this cohort.
