[Morphologic findings in chronic abuse of heroin and pervitine]

In a deceased 39-year-old man with a history of 10-year consumption of heroin and pervitin the authors made histological and immunohistochemical examinations of organs focused on detection of old and recent pathological changes. In the brain they detected oedema, venostasis, inflammatory infiltrates in the wall and surroundings of some vessels and hypoxic changes of neurons with a drop or disappearance of neuron-specific enolase. The myocardium was marked by oedema of the interstitium, focal diminution to disappearance of basophilia of myocyte nuclei with increased eosinophilia of some fibres and smaller and larger foci of fibrosis formed by mature and less mature connective tissue. Immunohistochemical examination revealed focal fibrinogen deposits in myocytes. A surprise was to a certain extent the finding of dispersely distributed caspase-8 in myocytes, caspase being one of the substances signalizing apoptosis. On microscopic examination of the lungs severe haemorrhagic oedema dominated. In the liver they found acute venostasis and chronic inflammatory changes with connective tissue proliferation in the portal areas. The finding in the kidneys suggested acute tubular nephrosis. The authors discuss the problem of direct toxicity of the ingested drugs, the influence of repeated states of hypoxia and infection.
