Abstract BACKGROUND: Secondary sclerosing cholangitis has clinical features similar to primary sclerosing cholangitis but originates from a known pathological entity. Secondary sclerosing cholangitis has not been investigated in patients with drug-induced liver injury. METHODS: Overall 102 patients diagnosed with drug-induced liver injury were identified and magnetic resonance cholangiopancreatography images of 25 patients were reviewed. RESULTS: Ten patients (all females) out of 102 had confirmed features of secondary sclerosing cholangitis on biliary imaging. Overall 70\% of patients with sclerosing cholangitis had jaundice vs. 25\% without sclerosing cholangitis (p<0.01). All sclerosing cholangitis patients had cholestatic/mixed type of liver injury and compared with patients with cholestatic/mixed liver injury without confirmed abnormal MRCP (n=52), they also had more frequently jaundice, 70\% vs. 23\% (p=0.0065), higher peak alkaline phosphatase 551 (352-716) vs. 329 (202-543) (p=0.055) and longer time to resolution of liver injury 152 days (123-353) vs. 62 days (36-91) than patients without confirmed sclerosing cholangitis (p<0.0009). CONCLUSIONS: Our results indicate that drugs can lead to bile duct injury visualized on imaging. This should be a part of the differential diagnoses of secondary sclerosing cholangitis. These patients were more likely to present with jaundice and longer recovery of liver injury than other patients with cholestatic/mixed type of drug-induced liver injury.
