INTRODUCTION: Adult Primary Sclerosing Cholangitis (PSC) subjects have worse outcomes compared to pediatric PSC subjects. The reasons for this observation are not completely understood.
METHODS: In this single-center, retrospective (2005-17) study we compared clinical information, laboratory data, and previously published MRCP-based scores between 25 pediatric (0-18 years at diagnosis) and 45 adult (19 years and above) subjects with large duct PSC at the time of diagnosis. For each subject, radiologists determined MRCP-based parameters and scores after reviewing the MRCP images.
RESULTS: The median age at diagnosis for pediatric subjects was 14 years, while that of adult subjects was 39 years. At the time of diagnosis, adult subjects had a higher incidence of biliary complications like cholangitis and high-grade biliary stricture (27% vs. 6%, p = 0.003) and higher serum bilirubin (0.8 vs. 0.4 mg/dl, p = 0.01). MRCP analysis showed that adult subjects had a higher incidence of hilar lymph node enlargement (24.4% vs. 4%, p = 0.03) at diagnosis. Adult subjects had worse sum-IHD score (p = 0.003) and average-IHD score (p = 0.03). Age at diagnosis correlated with higher average-IHD (p = 0.002) and sum-IHD (p = 0.002) scores. Adult subjects had worse Anali score without contrast (p = 0.01) at diagnosis. MRCP-based extrahepatic duct parameters and scores were similar between groups.
DISCUSSION: Adult PSC subjects may have higher severity of disease at diagnosis compared to pediatric subjects. Future prospective cohort studies are required to confirm this hypothesis.
