AI Article Synopsis

  • The study aimed to compare sleep quality between opioid-dependent patients on methadone maintenance therapy and opioid-naive individuals in Malaysia.
  • Opioid-dependent patients had higher sleep disturbance scores, indicating significantly worse sleep quality compared to the opioid-naive group.
  • The findings suggest that addressing sleep issues in opioid-dependent patients could enhance their overall treatment outcomes and quality of life.

Article Abstract

Background/aim: Sleep disturbances may contribute to poor treatment outcomes in opioid-dependent patients. The extent to which the sleep profiles of opioid-dependent patients differ from those of the general Malaysian population is not documented. This study compared opioid-naive subjects and opioid-dependent patients on methadone maintenance therapy (MMT) in terms of their sleep quality.

Materials And Methods: Participants comprised Malay male opioid-naive subjects (n = 159) and opioid-dependent patients (n = 160) from MMT clinics in Kelantan, Malaysia, between March and October 2013. Sleep quality was evaluated using the translated and validated Malay version of the Pittsburgh Sleep Quality Index (PSQI).

Results: The opioid-dependent patients exhibited higher global PSQI scores [adjusted mean (95% CI) = 5.46 (5.02, 5.90)] than the opioid-naive group [4.71 (4.26, 5.15)] [F (1, 313) = 4.77, P = 0.030].

Conclusion: This study confirmed the poorer sleep quality among opioid-dependent patients on MMT, as manifested by their higher global PSQI scores. The sleep complaints in this patient population are a factor to consider and, when necessary, sleep evaluation and treatment should be undertaken to improve MMT patients' quality of sleep and overall treatment outcome.

The opioid crisis has claimed approximately one million lives in the United States since 1999, underscoring a significant public health concern. This surge in opioid use disorder (OUD) fatalities necessitates improved therapeutic options. Current OUD therapies often require daily clinical visits, leading to poor patient compliance and high costs to the health systems.

Article Synopsis
  • The study investigates the quality of life (QoL) perceptions among long-term methadone-dependent patients (MDPs) undergoing methadone maintenance treatment (MMT) for opioid use disorder (OUD).
  • Using qualitative methods, the research involved in-depth interviews with 25 MDPs to explore their experiences and satisfaction in various life aspects post-treatment.
  • Key findings revealed themes of improved physical and mental health, a sense of purpose in life, positive self-perception, enhanced social support, marital satisfaction, and challenges related to fatigue, stigma, and financial strain associated with MMT.

Objectives: Methadone is a long-acting synthetic agonist of opioid receptors, which is used as an analgesic and as an alternative treatment in opioid-dependent patients. Clinical manifestations of methadone poisoning include miotic pupils, low levels of consciousness (LOC), respiratory depression or apnea, and coma and death. Considering the high consumption of methadone in society and the prevalent instances of overdose and poisoning, whether accidental or intentional, the authors decided to investigate the clinico-epidemiological, diagnostic, and therapeutic characteristics of methadone poisoning in the Mazandaran province, northern Iran, from 2020 to 2022.
