Abstract

Background: Primary biliary cholangitis (PBC) can impact both the quality of life and the survival of patients. The study aimed to determine the survival rate and associated variables in patients with PBC. Materials and Methods: This cohort research comprised 65 patients diagnosed with PBC who were admitted to the pathology section between January 2010 and December 2019. Survival was determined by reviewing hospital medical data and following up with the patients. The impact of demographic factors, clinical, laboratory, and histopathological aspects on patient survival time was investigated using Kaplan-Meier survival analysis and Cox regression. Results: The average period of follow-up was 6.25 years with a standard deviation of 3.2 years. In surviving patients, the baseline bilirubin level was 2.83, but in deceased or transplanted patients, it was 8.95 (P = 0.002). The baseline albumin level was 3.99 in surviving patients and 3.66 in deceased or transplanted patients (P = 0.024). The incidence of cirrhosis in those who survived was 1.8%, but in patients who died or underwent a transplant, it was 40%. Out of 65 cases, 3 patients (4.7%) died and 7 (10%) had liver transplants. Survival rates of patients vary based on factors such as jaundice (P = 0.002), weariness (P = 0.03), cirrhosis (P < 0.001), and vitiligo (P = 0.033). There were notable variations in the average Mayo score between the two groups of patients who had liver transplantation and survived, with scores of 7.21 and 5.61, respectively. Conclusion: The study found that aspartate aminotransferase and alanine aminotransferase levels, baseline and final bilirubin, albumin, antinuclear antibody, the presence of cirrhosis, and jaundice significantly influenced patient survival with PBC. © 2024 Journal of Research in Medical Sciences.
