Elevated Plasma Homocysteine Concentration in Opium-Addicted Individuals

Area of Science:

• Cardiovascular Disease Research
• Clinical Chemistry
• Epidemiology

Background:

• Opium use and elevated homocysteine are known risk factors for atherosclerosis and coronary heart disease.
• The relationship between opium addiction and homocysteine levels has not been previously studied.

Purpose of the Study:

• To investigate the potential correlation between opium addiction and elevated plasma homocysteine concentration.
• To explore opium addiction as a novel risk factor for hyperhomocysteinemia.

Main Methods:

• A population-based epidemiological study involving 217 participants (103 opium-addicted, 114 non-addicted) from the Kerman Coronary Artery Disease Risk Study (KERCADRS).
• Serum homocysteine levels were measured using an enzyme immunoassay kit.

Main Results:

• Opium-addicted individuals had significantly higher serum homocysteine levels (11.49 ± 7.45 μmol/l) compared to non-addicted individuals (8.02 ± 3.87 μmol/l).
• 21.3% of opium users and 3.2% of non-users exhibited homocysteine concentrations > 15 μmol/l (P < 0.001).
• Opium addiction was strongly associated with elevated homocysteine levels (OR = 8.244) and predicted higher homocysteine concentrations (beta = 3.524).

Conclusions:

• Opium consumption is strongly associated with elevated plasma homocysteine concentrations.
• Opium addiction increases the risk of developing hyperhomocysteinemia, a potential contributor to cardiovascular disease.
