It is associated with mutations in ATP8B1 (BRIC1) or ABCB11 (BRIC2), with triggers including infections, medications, or hormonal changes. Fewer than 50 cases have been reported in the U.S. Diagnostic overlap with other cholestatic liver diseases, particularly drug-induced liver injury (DILI), complicates recognition. The Luketic and Shiffman criteria offer a clinical framework, though not formally validated. We present a case of suspected BRIC with possible DILI, highlighting diagnostic challenges.
Case Description/
Methods: A 26-year-old male presented with one month of jaundice, dark urine, pale stools, nausea, and right upper quadrant pain. He had a flu-like illness two weeks prior and began pantoprazole one month before symptoms. He was unsure of any past jaundice. Family history included jaundice in his grandfather and unspecified cancer. Exam showed scleral icterus without hepatosplenomegaly. Labs revealed total bilirubin 10 mg/dL (peaking at 30.8), mildly elevated ALP, AST, ALT, normal GGT, hemoglobin 12.2 g/dL, and elevated ferritin. Workup for hereditary hemochromatosis, autoimmune, infectious, metabolic, and toxic causes was negative. Imaging (ultrasound, CT, MRCP) showed no obstruction or structural abnormalities. Cholestyramine provided partial symptom relief. He returned 2.5 weeks later with recurrent symptoms and weight loss. Ursodiol was started, with subsequent improvement. Liver biopsy showed lobular cholestasis, mild periportal inflammation, and focal bile duct proliferation; findings consistent with BRIC but not excluding DILI. Genetic testing was recommended. Discussion: This case met clinical, biochemical, and histologic features of BRIC, likely triggered by a viral illness. However, pantoprazole use raised concern for DILI or a mixed etiology. Although BRIC typically presents with recurrent episodes, this may represent an initial manifestation, further complicating differentiation from idiopathic or drug-related cholestasis. Liver biopsy supported BRIC but was not definitive. Genetic testing for ATP8B1 and ABCB11 may confirm diagnosis, though not timely for acute decisions. This case highlights the importance of considering BRIC in patients with unexplained cholestasis, especially when drug exposure and viral illness are present. Early recognition can help avoid unnecessary interventions and guide management.
