Liver pathology in fatal drug addiction
Abstract:
Liver sections from 273 drug addicts submitted to medicolegal autopsy at the Institute of Forensic Medicine in Copenhagen in the period 1975-1979 were studied. In 65% of the cases non-specific portal inflammation only was found. Birefringent material--identified as the mineral talc (magnesium silicate) was observed in 38% of the cases; in these cases non-specific portal inflammation was always present. Changes compatible with acute or chronic persistent hepatitis or hepatitis sequelae were observed in 8% of the cases; cirrhosis in 3%. HBs-antigens were detected in 4%. In 22% fatty infiltration was present; in 4% as the only abnormal finding. Finally no pathological changes were found in 6%. The results were related to anamnestic information of kind and duration of drug abuse and to the cause of death. Furthermore a comparison was performed between the groups with and without birefringent material. The data suggest that the birefringent material may be of importance to the pathogenesis of the non-specific portal inflammation.
Insights
Drug addicts
Area of Science:
- Forensic pathology
- Hepatology
- Toxicology
Background:
- Drug abuse can lead to various liver pathologies.
- Non-specific portal inflammation is a common finding in drug addicts.
- The role of specific adulterants in drug abuse-related liver disease requires further investigation.
Purpose of the Study:
- To investigate the liver pathology in a cohort of drug addicts.
- To determine the prevalence of specific findings such as non-specific portal inflammation, hepatitis, cirrhosis, and fatty infiltration.
- To explore the association between birefringent material (talc) and liver inflammation in this population.
Main Methods:
- Histopathological examination of liver sections from 273 drug addicts.
- Identification of birefringent material using microscopy.
- Correlation of pathological findings with drug abuse history and cause of death.
Main Results:
- Non-specific portal inflammation was found in 65% of cases.
- Birefringent material, identified as talc, was present in 38% of cases and always associated with portal inflammation.
- Hepatitis (acute/chronic/sequelae) was observed in 8%, cirrhosis in 3%, and fatty infiltration in 22%.
Conclusions:
- Talc (magnesium silicate) is frequently found in the livers of drug addicts.
- The presence of talc is strongly associated with non-specific portal inflammation.
- Talc may play a significant role in the pathogenesis of non-specific portal inflammation in drug abusers.
