<b><i>Background:</i></b> Research on quality of life (QoL) of chronically ill patients provides an opportunity to evaluate the efficacy of long-term treatments. Although it is established that opioid replacement therapy is an effective treatment for opioid-dependent patients, there is little knowledge about physical and psychological functioning of QoL for different treatment options. <b><i>Objectives:</i></b> Altogether, 248 opioid-dependent patients receiving substitution treatment with either methadone/levomethadone (<i>n</i> = 126), diamorphine (<i>n</i> = 85), or buprenorphine (<i>n</i> = 37) were recruited in 6 German therapy centers. <b><i>Methods:</i></b> Sociodemographic data were collected. QoL – physical and psychological functioning – for different substitutes was assessed using the <i>Profile of the Quality of Life in the Chronically Ill</i> (PLC) questionnaire. <b><i>Results:</i></b> Patient groups were similar regarding age and duration of opioid dependence. Employment rate was significantly higher (<i>p</i> &#x3c; 0.005, φ = 0.22) in the buprenorphine group (46%) compared to methadone (18%). Dosage adjustments were more frequent (<i>p</i> &#x3c; 0.001, φ = 0.29) in diamorphine (55%) than in methadone (30%) or buprenorphine (19%) patients. Buprenorphine and diamorphine patients rated their physical functioning substantially higher than methadone patients (<i>p</i> &#x3c; 0.001, η² = 0.141). Diamorphine patients reported a higher psychological functioning (<i>p</i> &#x3c; 0.001, η² = 0.078) and overall life improvement (<i>p</i> &#x3c; 0.001, η² = 0.060) compared to methadone, but not compared to buprenorphine patients (both <i>p</i> &#x3e; 0.25). <b><i>Conclusion:</i></b> Measurement of important QoL aspects indicates significant differences for physical and psychological functioning in patients receiving the substitutes methadone/levomethadone, diamorphine, and buprenorphine. This could be relevant for the differential therapy of opioid addiction.

Diamorphine was first legalized as a novel treatment option for heroin dependence in Germany in 2009. Today, specialized clinics in ten German cities provide diamorphine to heavily addicted patients. As the medical and societal context of diamorphineassisted therapy is evolving, continued research into patients' perceptions of opioid replacement therapy remains important. From February 2018 to June 2018, we conducted a survey study of outpatients on maintenance treatment with either diamorphine (n=85) or methadone/levomethadone (n=126). Patients were asked to complete a self-report questionnaire querying, besides socio-demographic information, the study participant's satisfaction with the substitute drug, relapse with illicit drugs, patterns of craving, and alcohol consumption. Duration of opioid dependence did not differ significantly between groups. Patients on diamorphine were approximately three years younger than patients on methadone / levomethadone. They had a higher frequency of daily drug intake and had had their dosage adjusted more often during the preceding six months. Still, diamorphine patients reported greater satisfaction with their substitute drug in tandem with significant reductions in relapse-related behaviors and cravings. While the most common relapse reported by patients on methadone replacement was heroin relapse (68%), most instances of illicit drug use in the diamorphine group involved cocaine (48%). Although self-reported alcohol consumption did not differ significantly between groups, a higher percentage of diamorphine patients than methadone patients endorsed decreased alcohol consumption since entering therapy. Taken together, these findings point to meaningful differences between diamorphine and methadone / levomethadone in opioid

A 42-year-old patient was admitted with slowly progressive gait disturbance over a period of ten years. The patient complained of regurgitation and fatigue since childhood. Clinical examination revealed nasal voice, distal amyotrophic motor deficit with pyramidal signs, mild intellectual disability, increased skin pigmentation, and reduced body weight (BMI: 16.6 kg/m2). Schirmer test revealed bilateral alacrima and barium swallow confirmed achalasia cardia. Cortisol level was undetectable, while adrenocorticotrophic hormone was elevated.

The 2018 European Union (EU) approved weekly and monthly subcutaneous buprenorphine depot injection (BUP-XR), for opioid substitution medication proved to offer some specific treatment benefits. The present study examines the process of switching from buprenorphine sublingual tablets (BUP-SL) to BUP-XR from a patient's point of view. In total, nine patients were surveyed by means of an openanswer questionnaire regarding course and side effects of the medication switch. Six of these patients were surveyed in more detail under BUP-SL, as well as 4 and 16 weeks after the switch to BUP-XR by means of a test battery of questions on socio-demography, withdrawal symptoms, craving, physical well-being, treatment satisfaction and concomitant use of illegal substances. Patients reported significant worse physical well-being and lower treatment satisfaction in 4 weeks compared with 16 weeks after the medication switch to the BUP-XR. Furthermore, they reported significant more frequent co-use of illicit drugs, worse physical well-being, lower treatment satisfaction and more craving experience 4 weeks after the switch compared with the treatment under BUP-SL. Patients 16 weeks under BUP-XR reported significant more illicit co-use and lower treatment satisfaction compared with patients under BUP-SL. Connections between therapy dissatisfaction, physical discomfort, experienced craving and drug co-consumption were discovered. In the first weeks after the medication switch, patients experience potentially distressing symptoms, which, however, seem to diminish over time. Close supervision and comprehensive patient education on possible burdens of the medication switch to the BUP-XR might prevent unfavourable treatment courses and premature therapy dropouts.
