Nonsteroidal anti-inflammatory drugs-associated vanishing bile duct syndrome: a real-world retrospective and disproportionality analysis.

Introduction: Vanishing bile duct syndrome (VBDS) is a potentially fatal adverse reaction triggered by certain medications. The association between nonsteroidal anti-inflammatory drugs (NSAIDs) and VBDS is based on case reports. We explored the reporting prevalence and evaluated the clinical features of NSAID-related VBDS.

Research Design And Methods: Adverse event reports of VBDS associated with NSAIDs from 2004 to 2023 in the FAERS database were retrieved, and disproportionality analyses were conducted to detect risk signals. Case reports from 2000 to 2023 on NSAID-induced VBDS were retrieved for retrospective analysis.

Results: We obtained 87 VBDS reports from the FAERS database. Ibuprofen had the greatest proportion of VBDS (63.2%), while loxoprofen had the highest positive signal value. Sixteen case reports showed evidence of VBDS, with 37.5% of children. The median age was 29 years; typical initial symptoms included rash (60.0%), jaundice (53.3%), fatigue/asthenia (33.3%), and SJS/TEN (53.3%). The median onset time of VBDS was 4 weeks. All cases had abnormal liver function tests, with the median level of TBIL being 20.0 mg/dl. The overall prognosis is poor, with 50% of patients achieving clinical remission.

Conclusion: Four NSAID agents had significant reporting associations with VBDS. Prescribers should be more aware of this risk and identify signs/symptoms earlier.
