Parenteral drug users show altered trace element levels, with lower zinc and iron, and higher copper. Abstinence impacts zinc and lithium levels in drug addicts.

Area of Science:

  • Biochemistry
  • Clinical Chemistry
  • Toxicology

Background:

  • Trace elements play crucial roles in biological functions.
  • Parenteral drug use is associated with various health complications.
  • Understanding trace element status in drug addicts is important for health management.

Purpose of the Study:

  • To investigate the levels of specific trace elements (zinc, copper, magnesium, iron, lithium) in parenteral drug addicts.
  • To compare trace element profiles between drug addicts and healthy controls.
  • To explore the relationship between abstinence duration and trace element levels.

Main Methods:

  • Atomic absorption spectrophotometry was used for trace element analysis.
  • Plasma and erythrocyte samples were analyzed from 120 subjects.

Related Experiment Videos

  • Subjects included 20 healthy controls and 100 parenteral drug addicts (heroin and mixed drug users).

    • Main Results:

    • Drug addicts exhibited significantly decreased plasma zinc and intraerythrocytic zinc and iron.
    • Drug addicts showed significantly increased plasma and intraerythrocytic copper levels compared to controls.
    • A longer abstinence period (>10 days) correlated with lower plasma zinc and lithium levels.

    Conclusions:

    • Parenteral drug addiction significantly alters trace element homeostasis, particularly affecting zinc, copper, and iron.
    • Abstinence duration is a factor influencing specific trace element levels in drug users.
    • Trace element analysis may offer insights into the physiological impact of drug addiction.
