Sclerosing cholangitis is a rare progressive cholestatic disease that is classified as secondary sclerosing cholangitis when it is caused by an identifiable cause. Sclerosing cholangitis has been linked to infections like COVID-19 and parasitic infections like Clonorchis sinensis and Ascaris lumbricoides. However, leptospirosis has not been linked to sclerosing cholangitis in the medical literature. In this article, we report a 37-year-old gentleman who was diagnosed with leptospirosis, worsened by painless cholestasis, while he was improving from leptospirosis. Magnetic resonance cholangiopancreatography revealed multiple short-segment biliary strictures, segmental dilatation, and mural irregularities in both intrahepatic ducts confirming the diagnosis of sclerosing cholangitis. After ruling out other potential causes and considering the initial presentation during a leptospirosis infection, we concluded that leptospirosis caused secondary sclerosing cholangitis. We report this as the first case of secondary sclerosing cholangitis in a leptospirosis patient without renal, respiratory, or cardiac complications, emphasizing the importance of ruling out this cause in a leptospirosis patient with persistent cholestasis.

Introduction: Observational studies have shown that gallstone disease (GSD), cholecystitis, cholangitis, polyp of gallbladder, viral hepatitis, pancreatitis and gastrointestinal (GI) traits such as H. pylori infection, inflammatory bowel disease, and digestive ulcer are associated with the risk of biliary tract cancer (BTC). However, no study has explored their causal associations.

Primary sclerosing cholangitis (PSC) is a rare autoimmune disease. This study aims to describe the baseline characteristics and clinical outcomes of Chinese PSC patients and explore risk factors associated with prognosis, addressing the lack of long-term prognostic analysis in China. Clinical data of PSC patients were retrospectively collected from May 2009 to June 2023 in Beijing Friendship Hospital Affiliated to Capital Medical University, and patient follow-up was conducted through outpatient visits, telephone calls, and medical record reviews.

Primary sclerosing cholangitis (PSC) is a progressive autoimmune hepatobiliary disease characterized by fibrotic strictures in the bile ducts, leading to chronic cholestasis and cirrhosis. Magnetic resonance cholangiopancreatography (MRCP) is a noninvasive method for evaluating the condition of the bile ducts, and has high sensitivity and specificity, making it the first-line diagnostic tool for PSC. However, the importance of endoscopic retrograde cholangiopancreatography (ERCP) remains unchanged.
