Heparin can cause liver injury (hepatotoxicity), which is often missed in clinical practice. This report highlights rapid liver enzyme elevations after heparin initiation, suggesting a need for increased awareness.
Area of Science:
- Biochemistry
- Hepatology
- Pharmacology
Background:
- Heparin-induced hepatotoxicity is a known, albeit rarely diagnosed, clinical complication.
- Elevated liver enzymes are a key indicator of potential drug-induced liver injury.
Observation:
- Two patient cases demonstrated elevated aminotransferase levels following heparin administration.
- One patient exhibited enzyme elevations within 8 hours of heparin treatment, a notably rapid onset.
Findings:
- The rapid onset of liver enzyme elevation in one case is unprecedented in existing literature.
- These findings underscore the potential for acute hepatic response to heparin therapy.
Implications:
- Increased clinical vigilance for heparin-induced hepatotoxicity is warranted, especially with rapid enzyme changes.
- This biochemical observation may prompt further investigation into the mechanisms of heparin-induced liver injury.
