Impulsive Personality Traits Mediate the Relationship Between Attention-Deficit/Hyperactivity Disorder Symptoms and Psychiatric Comorbidity among Patients with Severe Alcohol Use Disorder.

OBJECTIVE: Attention-deficit/hyperactivity disorder (ADHD) is an established risk factor for developing alcohol use disorder (AUD), and AUD-ADHD comorbidity is associated with additional psychiatric diagnoses. Several lines of evidence support the role of impulsivity as a pathway of these relationships; however, impulsivity is not a unitary construct. Thus, we sought to explore whether separate aspects of impulsivity may explain the relationship between ADHD symptoms and psychiatric comorbidity among inpatients (N = 136) with AUD. Methods: We assessed ADHD symptoms (childhood ADHD [Wender Utah Rating Scale], adult ADHD [Adult ADHD self-report scale]), health-related quality of life (HRQL; EQ-5D-5L), psychiatric comorbidity (Mini International Neuropsychiatric Interview), and impulsive personality traits (Urgency, Premeditation, Perseverance, Sensation seeking [UPPS] scale). Results: 19% of patients screened positive in the retrospective assessment of childhood ADHD, and 17% for adult ADHD. Participants reported moderate levels of problem severity in the HRQL dimensions, and 65% had ≥1 current psychiatric disorders other than AUD and ADHD. Multiple mediation indicated that there was a significant direct effect of childhood ADHD symptoms on psychiatric comorbidity (ß = 0.224, 95% CI [0.080, 1.114]), and indirect effects of both reacting impetuously when experiencing negative emotions (negative urgency; ß = 0.999, 95% CI [0.043, 0.461]) and the tendency to not finish tasks (lack of perseverance; ß = 0.075, 95% CI [0.002, 0.297]). Conclusions: The subcomponents of impulsivity to react rashly when experiencing negative emotions and the tendency to not persist in activities seem to contribute to the relationship between ADHD symptoms (particularly those in childhood) and psychiatric comorbidity among patients with severe AUD.

Comparative study of the effectiveness of slow-release morphine and methadone for opioid maintenance therapy.

AIMS: Slow-release morphine may represent a much-needed new pharmacological treatment for opioid dependence. DESIGN: In a 14-week randomized, double-blind, double-dummy, cross-over study oral slow-release morphine was compared with methadone as a treatment for opioid dependency. During two study periods, each consisting of a 1-week titration and a 6-week fixed-dose treatment phase, medication was administered daily under supervised conditions. SETTING: The study was carried out at the Addiction Clinic, Department of Psychiatry, Medical University Vienna. PARTICIPANTS: Sixty-four subjects (56 males, eight females) with opioid dependence participated in the trial. MEASUREMENTS: Efficacy was evaluated on the basis of retention, use of illicit substances based on urinalysis, extent of drug cravings, withdrawal symptoms and general wellbeing. Safety was assessed on the basis of adverse events and clinical and physical examination. Demographic and baseline characteristics were assessed using the European Addiction Severity Index. FINDINGS: Fifty-five patients (86%) completed the study, with a mean methadone dose of 85 mg and a mean slow-release morphine dose of 680 mg. No significant differences in retention or use of illicit substances (opioids, benzodiazepines, cocaine) were observed, irrespective of treatment group or medication. However, patients receiving slow-release morphine had significantly lower depression (P < 0.001) and anxiety scores (P = 0.008) and fewer physical complaints (P < 0.001). CONCLUSIONS: Oral slow-release morphine is as effective as methadone in the treatment of opioid dependency, with comparable safety and tolerability and a greater benefit on patient wellbeing. Greater pharmaceutical diversity represents a modern development in mainstream medicine. Slow-release morphine might represent a future treatment option that will improve long-term outcomes for this target group.

[Slow-release morphine hydrochloride for maintenance therapy of opioid dependence]. / Retardiertes Morphinhydrochlorid in der Erhaltungstherapie Opioidabhängiger.

INTRODUCTION: In Austria, methadone, buprenorphine as well as oral slow-release morphine are used for the treatment of opioid dependence. This controlled examination marks the first time that oral slow-release morphine hydrochloride is applied for maintenance therapy in opioid dependent subjects. METHODS: In order to evaluate the effectiveness of this psychopharmacological medication, we examined patients over a three-week period. Outcome measures were retention rate, additional consumption and the evaluation of opioid withdrawal 24 hours after the last oral medication. RESULTS: Sixty-seven patients were included; sixty-four patients completed the study, representing a retention rate of 94%. During the three-week period, a significant improvement in well-being and a significant reduction in heroin, cocaine and benzodiazepine craving (p < 0.0001) was evaluated. Furthermore, there was a significant reduction of additional consumption of benzodiazepines in supervised urinalysis. Additional consumption of cocaine remained unchanged. Laboratory results showed a significant reduction of CK over the course of investigation. DISCUSSION: The high retention rate of 94% implies a good acceptance and efficacy of the substance. The reduced CK is consistent with a reduction in intravenous application of illegal substances. However, randomized double-blind, double-dummy studies with oral slow-release morphine are needed in order to meet criteria for evidence based medicine.

Use of slow-release oral morphine for the treatment of opioid dependence.

AIMS: In addition to methadone, other synthetic opioids are now available for the treatment of opioid dependence. The study investigated the treatment satisfaction of oral slow-release morphine for maintenance therapy in opioid-dependent patients in an open-label 3-week study. DESIGN: We evaluated the treatment satisfaction of oral slow-release morphine hydrochloride for 3 weeks in 110 patients meeting the diagnosis of opioid dependence (DSM-IV 304.0) or polysubstance dependence (DSM-IV 304.9). MEASUREMENTS: Primary outcome measures were the study retention rate, urinalysis for additional illicit consumption other than heroin, cravings and withdrawal symptoms 24 h after the last intake of the medication (duration of action of treatment). FINDINGS: In total, 103 patients completed the study, representing a retention rate of 94%. Patients reported significant improvements in somatic complaints, as well as significant reductions in heroin and cocaine cravings (p < 0.0001) and in additional consumption of cocaine in supervised urinalysis (p = 0.0083). Additional illicit consumption of benzodiazepines remained unchanged. CONCLUSIONS: The high study retention rate implies a good acceptance of slow-release acting oral morphine. However, randomised, double-blind, double-dummy studies with a longer investigational period are needed to meet criteria for evidence-based medicine.

Occurrence of delirium after a short-term intake of olanzapine.

Olanzapine is an atypical antipsychotic drug, which is claimed to have fewer side effects than conventional antipsychotics. We report three cases where patients developed a classic delirium within a few days after first intake of olanzapine. The symptoms fulfilled all criteria of DSM-IV for delirium, and rapidly diminished after discontinuation of olanzapine. Additional reasons for the development of the delirias are possible, but less likely. Special awareness and future research of this phenomenon is highly indicated because of the common use of this drug.
