Abstract
Opioid addiction influences many physiological functions including reactions of the immune system. The objective of this study was to investigate the immune system function in heroin addicted patients undergoing methadone maintenance treatment (MMT) compared to healthy controls. We tested the cytokine production of IL-1β, IL-6, IL-8, IL-10 and tumor necrosis factor (TNF)-α from a group of heroin addicts (n=34) and healthy controls (n=20). The results show that production of IL-1β, IL-6 and IL-8 was significantly higher in the group of methadone-maintained patients than in the healthy control group. Plasma TNF-α and IL-6 levels were significantly correlated with the dairy methadone dosage administered, and the IL-1β level was significantly correlated with the duration of methadone maintenance treatment. These findings suggest that methadone maintenance treatment influences the immune system functions of opioid-dependent patients and may also induce long-term systemic inflammation.
