A Bibliometric Analysis of Immunological Research in Primary Biliary Cholangitis: Global Patterns and Emerging...

Despite the significant advances in autoimmune research, primary biliary cholangitis (PBC) remains a clinically challenging and incompletely understood disease, with its exact causes and molecular mechanisms still elusive. The immune system exerts crucial pathogenic effects throughout PBC development, from initial biliary injury to end-stage cirrhosis. Despite decades of investigation, the current understanding of PBC pathogenesis remains fragmented, particularly regarding the immune mechanisms involved in the disease. To address this, we conducted a bibliometric analysis of immunological studies on PBC, utilizing data from the Web of Science database, which covers publications from 1970 to 2023, and identified 2,042 studies for analysis. The findings revealed a steady increase in research activity over the decades. Our analysis revealed a consistent upward trend in PBC-related studies, with an average growth rate of 14.45%. The United States leads as the top contributing country, with the University of California, Davis, and Dr. Gershwin M. Eric emerging as the most influential institution and author, respectively. Among journals, Hepatology is the most prominent, with the highest number of citations and co-citations. Recent advances in diagnostic techniques have substantially improved early detection rates of PBC while dramatically decreasing instances of disease decompensation. This paradigm shift has redirected research priorities toward innovative disease management strategies and patient-centered care approaches. This synthesis presents a unified framework for PBC immunopathogenesis, pinpointing critical knowledge gaps and high-potential research trajectories in disease mechanisms and therapeutic innovation.
