33. Drug-induced liver injury (DILI)
1. Mimic primary liver disease: histology
2. Inadequate clinical history and human mind
1) Onset of liver disease following Rx
2) Multiple drugs involved
3) Herbal agents: HILI
4) Over-the-counter medications
5) Household, occupational or industrial toxins
Unpredictable/idosyncratic : under-report
genetics, complexity, latency, chronicity
34. How to investigate DILI
Dr. Dame Sheila Sherlock
1. Suspect any drug
2. Detail drug history
3. De-challenge: fall of LFTs
4. Re-challenge
5. Exclude other liver disease
Viruses, autoimmune, obstruction
6. Biopsy “When you have eliminated the impossible, whatever remains,
however improbable, must be the truth?“
