AI Article Synopsis
- The study investigates and compares characteristics of autoimmune liver diseases (AILDs), specifically primary biliary cholangitis (PBC), autoimmune hepatitis (AIH), and PBC-AIH overlap syndrome (OS) in an Asian population.
- It shows that PBC patients are older, have higher female-to-male ratios, and exhibit greater rates of complications such as cirrhosis and dyslipidemia compared to AIH patients, with notable differences in liver function markers and mortality rates.
- The research emphasizes the need for special attention to older PBC patients, particularly females with obesity, due to their higher risks of liver complications and hepatocellular carcinoma (HCC).
Article Abstract
Background And Aim: The characteristics of autoimmune liver diseases (AILDs), including primary biliary cholangitis (PBC), autoimmune hepatitis (AIH), and PBC-AIH overlap syndrome (OS), have rarely been investigated and compared in Asia.
Methods: At the Taiwan tertiary referral center, 330 PBC patients (87% treated with ursodeoxycholic acid [UDCA]), 143 AIH patients (94.4% treated with immunosuppressive therapy [IST]) and 21 PBC-AIH OS patients (85.7% treated with UDCA and IST) were enrolled.
Results: Compared with AIH patients, PBC patients were older at baseline and had greater female-to-male sex ratios, alkaline phosphatase (ALP) and γ-glutamyl transferase (γ-GT) levels, and liver cirrhosis (LC), dyslipidemia, and hepatic and cardiometabolic complication rates. PBC patients had the lowest transaminase levels, whereas AIH patients had the highest transaminase levels. PBC patients had greater 22-year all-cause mortality and liver transplantation (ACMaLT) (43.5 vs 25.4%, P = 0.004), LC (75 vs 58.5%, P < 0.01), dyslipidemia (54.4 vs 45.9%, P = 0.001), and cerebrovascular accident (11.3 vs 0.8%, P = 0.019) cumulative incidences (CIs) than did AIH patients; PBC-AIH OS patients had greater systemic lupus erythematosus (28.9 vs 8.9%, P = 0.009) CI than did PBC patients. Baseline ALP (hazard ratio: 1.001), albumin (0.514), platelet count (0.997), and LC (3.438) were associated with ACMaLT; age (1.110), albumin (0.350), cirrhosis (46.219), and hepatitis C virus antibody positivity (5.068) were associated with hepatocellular carcinoma (HCC); and female sex (2.183) and body mass index (1.054) were associated with autoimmune diseases.
Conclusions: Compared with AIH patients, PBC patients had greater cardiometabolic CI, and ACMaLT CI, which was associated with cholestasis, liver functional reserve and LC. Older AILD patients with LC and females with obesity demand special caution for the development of HCC and extrahepatic autoimmune diseases, respectively.
