Kratom (Mitragyna speciosa)-Induced Hepatitis

Area of Science:

• Toxicology
• Hepatology
• Pharmacology

Background:

• Kratom (Mitragyna speciosa) is recognized for its opioid-like, stimulant, and analgesic properties.
• While its psychoactive effects are studied, kratom's toxicity, particularly hepatotoxicity, remains less understood.
• Existing literature lacks detailed histological descriptions of kratom-induced liver injury.

Observation:

• This case report details a patient experiencing drug-induced liver injury attributed to kratom consumption.
• Laboratory results revealed significant elevations in total bilirubin and alkaline phosphatase.
• Liver biopsy findings included a cholestatic pattern, portal inflammation, and novel perivenular necrosis.

Findings:

• Histopathological examination of the liver biopsy revealed a distinct canalicular cholestatic pattern.
• Mixed portal inflammation was observed, indicating an immune response within the liver.
• Newly described perivenular necrosis was a key finding, suggesting specific cellular damage patterns.

Implications:

• This study contributes crucial clinicopathologic data to the understanding of kratom-induced hepatotoxicity.
• The findings underscore the potential liver risks associated with increasing kratom use.
• Further research into kratom's toxicological profile is warranted due to its growing popularity.
