Sleeping Patterns in Patients with Opioid Use Disorder: Effects of Opioid Maintenance Treatment and Detoxification.

The aim of the study was to explore whether abstinent patients on recent opioid detoxification or on opioid maintenance treatment suffer from sleeping problems. 199 patients on opioid maintenance treatment (methadone, diacetylmorphine and buprenorphine) or recent opioid detoxification were included in this exploratory cross-sectional study. We used the Pittsburgh Sleep Quality Index (PSQI) and the Regensburger Insomnia Scale (RIS) in order to assess potential sleeping problems. There was a significant effect of the condition "opioid maintenance" or "recent opioid detoxification" on the total score of PSQI and RIS. All opioid maintenance drugs used by the study population were associated with more sleeping problems compared to the detoxification group when calculated with RIS values. Recently abstinent patients (opioid detoxification) displayed significantly fewer sleep disturbances than opioid-maintained patients. Since sleeping problems can seriously impair treatment success and quality of life, screening for sleep disturbances and their subsequent treatment is of pronounced relevance.

[Adult attention deficit hyperactivity disorder (ADHD) with comorbid addictive disorder. Therapeutic challenges using the example of a survey of clinical practice]. / ADHS im Erwachsenenalter und komorbide Suchterkrankungen : Therapeutische Herausforderungen am Beispiel einer Praxiserhebung.

BACKGROUND: ADHD in childhood and adolescence is characterized by the symptoms hyperactivity, impulsivity, and inattentiveness; these symptoms may persist into adulthood or may manifest as restlessness, emotional instability, and disorganized behavior. In adults ADHD often occurs with increased substance use and is associated with an early onset of substance use, development of severe addiction, and decreased treatment effectiveness. METHOD: This overview will present and critically discuss current study results and evidence-based and consensus-oriented recommendations that ensure the most adequate care for patients with ADHD and addictive disorder. RESULTS AND CONCLUSIONS: For drug therapy, the current S3 guideline recommends methylphenidate, amphetamine salts, and atomoxetine, among others. Treatment of adult patients with ADHD and addiction with stimulants tends to be viewed critically; if required, long-acting medications should be used. Integrated treatment of ADHD and addiction, consisting of a combination of pharmacotherapy and psychotherapy, is recommended.

Concomitant drug abuse of opioid dependent patients in maintenance treatment detected with a multi-target screening of oral fluid.

BACKGROUND AND OBJECTIVES: Numbers of drug-related deaths have been growing in Europe and the USA, especially those attributable to mixed drug consumption. Overdose deaths account for about one third up to one half of all illicit drug deaths worldwide. In most cases opioids are involved. Opioid maintenance treatment (OMT) is a well-established therapy option among people with opioid dependence. The aim of this study was to assess concomitant substance abuse in opioid-dependent patients under OMT in two centers in Munich, Germany. METHODS: Oral fluid samples of opioid-dependent patients (n = 388) in OMT were randomly collected and analyzed by a multi-drug screening covering a wide range of psychotropic agents with UPLC-MS/MS techniques. RESULTS: Fifty-one percent of the patients had concomitant substance abuse of at least one non-prescribed substance, 32% were positive for substances that were not tested in routine urine diagnostics, especially pregabalin. Fifty-seven percent received take-home opioid medication, and 26% had contact with underage children. Among the take-home subgroup, a concomitant substance abuse of 43.5% was detected. Furthermore 52.5% of the patients with contact to underaged children exhibited concomitant substance abuse. CONCLUSIONS: Concomitant substance abuse is a serious issue among OMT patients. Screening for a broader range of substances than usually analyzed, reveals additional relevant abuse among OMT patients, including pregabalin-an anticonvulsant. SCIENTIFIC SIGNIFICANCE: Our study underscores the importance of monitoring a broad range of substances including others than usually screened in opioid-dependent patients in OMT.

High Concomitant Misuse of Fentanyl in Subjects on Opioid Maintenance Treatment.

BACKGROUND: Concomitant opioid misuse is an increasing problem in opioid maintenance treatment as it interferes with treatment success. OBJECTIVE: Therefore, the rates of concomitant fentanyl misuse in opioid maintained patients were investigated. METHODS: We conducted a cross-sectional study which consisted in collecting data via urine samples and questionnaires in Germany. Urine samples of patients on opioid maintenance treatment were gathered and fentanyl concentrations were measured from 2008 to 2012. An anonymous questionnaire provided data on the consumption of fentanyl as concomitant drug. Data were analyzed with descriptive statistics and group differences were calculated using the Chi-Square test. RESULTS: Among the total sample (urine probes of 960 patients), 6.8% opioid maintained patients had positive urine samples for fentanyl and 37.9% reported concomitant fentanyl misuse (401 of these patients filled out the questionnaire). A significant age-related association of concomitant fentanyl misuse was identified in the urine analyses (χ2 = 7.489; p = .024) and also in the questionnaire data (χ2 = 11.899, p = .003), indicating that young age increased the probability of fentanyl consumption. Patients receiving methadone had the highest rates of concomitant fentanyl misuse with 18.4% according to urine analysis. In addition, the results show that patients who are on diamorphine are significantly less likely to misuse fentanyl. CONCLUSIONS: Fentanyl is a frequently used concomitant drug. Especially young patients and patients taking methadone are at high risk. Because of the life-threatening consequences of fentanyl overdose, patients taking fentanyl should be intensively medically surveilled.

[Burden of disease and level of patient's medical care in substitution treatment for opiates]. / Krankheitslast und Versorgungsniveau bei opioidsubstituierten Patienten.

BACKGROUND AND PURPOSE: Within the framework of an interdisciplinary cooperation, the authors set up an on-site medical service provider in a specialized methadone substitution center in Germany. Here, they report on the prevalence of infectious and noninfectious diseases, and the vaccination status of substituted heroin-dependent patients. PATIENTS AND METHODS: All patients who visited the medical care service provider between February 2008 and December 2008 were included in this study. RESULTS: Ten patients (7%) were seropositive for the hepatitis A virus. Two patients (1.3%) suffered from chronic hepatitis B; 40 patients (27%) were cured after a hepatitis B infection. Additionally, 99 patients (68%) were infected with hepatitis C virus (HCV), and 41 patients (28%) had active hepatitis C. Furthermore, 48 hepatitis C patients (33%) were cured. Of those, 25 patients (17%) cleared the virus spontaneously and 23 (16%) after ribavirin/interferon combination therapy. Ten (7%) of 146 patients were infected with the human immunodeficiency virus (HIV). Of those, four patients had active hepatitis C, and five patients were cured after a hepatitis C infection. 18 patients (12%) were vaccinated against hepatitis A and 28 (19%) against hepatitis B. Two of the 41 patients with chronic hepatitis C were vaccinated against hepatitis A. The most frequent noninfectious diagnoses were arterial hypertension (n = 28), bronchial asthma (n = 8), and diffuse liver parenchymal damage (n = 12). CONCLUSION: These results emphasize that i.v. drug users on substitution therapy are an underserved collective with a high prevalence of disease. The challenge consists in facilitating this population access to internistic and infectious disease service. The offer of an on-site medical service was well accepted. This is essential for an ongoing reduction of HIV and HCV prevalence in the drug users.

Effects of haloperidol and risperidone on psychomotor performance relevant to driving ability in schizophrenic patients compared to healthy controls.

The effects of antipsychotic treatment on the psychomotor performance and driving ability of schizophrenic patients is subject of investigation. The present study was designed to evaluate the effects of an atypical neuroleptic (risperidone) in comparison to a conventional dopamine antagonist neuroleptic (haloperidol) on several dimensions of psychomotor performance (visual perception, attention, reaction time, and sensorimotor performance) considered to be of relevance in evaluating driving fitness. Psychomotor performance was assessed by means of the ART 90 (act-and-react test), a computerized test battery which is frequently used in diagnosis of psychomotor performance. The 40 participating patients were examined at discharge following psychopathological stabilisation; 20 received haloperidol medication, 20 received the atypical neuroleptic risperidone. Nineteen healthy individuals were studied as a control group. Our findings indicate a remarkably reduced psychomotor performance in both groups of schizophrenic patients compared to healthy controls. We did find a significant but low correlation between age and some items of the RST3 and between age and the tracking performance on the PVT. The younger patients showed a better test performance than older patients. The BPRS-score was significantly correlated with only two items of the RST3. However, patients under treatment with risperidone showed significantly better results compared to patients treated with haloperidol. Only one (5%) subject passed all subtests without major failures and could be regarded as competent to drive. Among patients with risperidone, seven patients (35%) passed all test parameters without major failures. Clinical implications of these findings are discussed.

Effects of haloperidol and atypical neuroleptics on psychomotor performance and driving ability in schizophrenic patients. Results from an experimental study.

The influence of antipsychotic treatment on the neuropsychological and psychomotor performance of schizophrenic patients is still a subject of investigation. The present study was designed to evaluate the effects of atypical neuroleptics in comparison with a conventional dopamine antagonist neuroleptic (haloperidol) on several dimensions of psychomotor performance (visual perception, attention, reaction time, and sensorimotor performance) considered to be of relevance in evaluating driving fitness. Psychomotor performance was assessed by means of the ART 90, a computerized Act and React Test which is generally used in diagnosis of psychomotor performance. The 49 participating patients were examined at discharge following psychopathological stabilisation; 20 received haloperidol, 29 received an atypical neuroleptic. Our findings demonstrate a remarkably reduced psychomotor performance in the haloperidol-treated group of schizophrenic patients compared with patients treated with atypical neuroleptics. Only 1 (5%) subject passed all subtests without major failures and could be regarded as competent to drive. Among patients with atypical neuroleptics, 7 patients (24%) passed all test parameters without major failures.
