Abstract:
A 41-y-o Pakistani man presented with psychosis, hyperthermia, rhabdomyolysis, and liver dysfunction approximately 6 h after i.v. injection of methamphetamine. Serum concentrations of methamphetamine and amphetamine on admission were 0.30 microg/mL and 0.04 microg/mL, respectively. Total serum bilirubin and alanine aminotransferase concentrations peaked on the 3rd hospital day at 8.6 mg/dL and 4155 IU/L, respectively, and gradually returned to normal with supportive care. The patient had no evidence of infectious hepatitis or intake of other drugs. Histologic examination of a liver biopsy specimen obtained on the 11th d showed confluent necrosis and ballooning degeneration in centrilobular zones. No inflammatory changes were seen in portal tracts. Liver damage can be a complication of illicit methamphetamine use, even in patients without viral infection or intake of other drugs.
Insights
Illicit methamphetamine use can cause severe liver damage, even without viral infections. This case highlights acute liver injury following methamphetamine injection, emphasizing the need for awareness among healthcare providers.
Area of Science:
- Toxicology
- Hepatology
- Emergency Medicine
Background:
- Methamphetamine (MAP) is a potent central nervous system stimulant with a high potential for abuse.
- While known for its neurotoxic effects, MAP's potential to cause acute liver injury (ALI) is less understood.
- This case examines ALI in the context of recreational MAP use.
Observation:
- A 41-year-old male presented with psychosis, hyperthermia, rhabdomyolysis, and liver dysfunction 6 hours post-intravenous MAP injection.
- Initial serum MAP and amphetamine levels were 0.30 µg/mL and 0.04 µg/mL.
- Liver enzymes, including total serum bilirubin and alanine aminotransferase, peaked on day 3, indicating significant hepatocellular damage.
Findings:
- Histological examination of a liver biopsy revealed centrilobular confluent necrosis and ballooning degeneration.
- No evidence of infectious hepatitis or other drug intake was found.
- The patient recovered with supportive care, suggesting MAP as the direct cause of liver injury.
Implications:
- Acute liver damage is a potential complication of illicit methamphetamine use.
- Clinicians should consider MAP toxicity in patients presenting with unexplained liver dysfunction, especially those with risk factors.
- Further research is needed to elucidate the mechanisms of MAP-induced hepatotoxicity.
