Former heroin-dependent alcohol use disorder patients. prevalence, addiction history and clinical features

Aims: To examine the prevalence of former heroin dependence (FHA) in Alcohol Use Disorder (AUD) patients; to compare the clinical characteristics of FHA-AUD patients versus AUD patients without any past use of heroin at alcohol treatment entry; to document the heroin dependence history of FHA-AUD patients, and review treatment strategies for this group. Methods: Retrospective case review of 448 consecutive AUD patients. Results: The annual entry of FHA-AUD showed stability over the study period of 3 years overall 60/ 448 (13.3%). FHA-AUD patients showed higher concomitant use of cocaine, benzodiazepines, cannabis and hallucinogens than other heroin addicts. They consumed higher amounts of alcohol at the beginning of their alcohol dependence history, and reached a high maximum level of alcohol consumption, than other AUD patients, and tended to have more physical disorders. The most important signals of FHA-AUD were polyabuse and older age at the time of presentation. FHA-AUD patients tended to have had a severe pattern of heroin dependence associated with inadequate agonist opiate treatment. Conclusions: The prevalence of FHA-AUD patients is not negligible. This may relate to previous inadequate treatment of heroin addiction contributing to the development of severe AUD. For these patients we propose a reconsideration of ‘soft’ (low dose) agonist opiate treatment

Harm Reduction as "Continuum Care" in Alcohol Abuse Disorder

Alcohol abuse is one of the most important risk factors for health and is a major cause of death and morbidity. Despite this, only about one-tenth of individuals with alcohol abuse disorders receive therapeutic intervention and specific rehabilitation. Among the various dichotomies that limit an effective approach to the problem of alcohol use disorder treatment, one of the most prominent is integrated treatment versus harm reduction. For years, these two divergent strategies have been considered to be opposite poles of different philosophies of intervention. One is bound to the search for methods that aim to lead the subject to complete abstinence; the other prioritizes a progressive decline in substance use, with maximum reduction in the damage that is correlated with curtailing that use. Reduction of alcohol intake does not require any particular setting, but does require close collaboration between the general practitioner, specialized services for addiction, alcohology services and psychiatry. In patients who reach that target, significant savings in terms of health and social costs can be achieved. Harm reduction is a desirable target, even from an economic point of view. At the present state of neuroscientific knowledge, it is possible to go one step further in the logic that led to the integration of psychosocial and pharmacological approaches, by attempting to remove the shadows of social judgment that, at present, are aiming for a course of treatment that is directed towards absolute abstention

The newer opioid agonist treatment with lower substitutive opiate doses is associated with better toxicology outcome than the older harm reduction treatment

Background: Charge-free heroin use disorder treatment in Italy follows two main approaches, i.e., harm reduction treatment (HRT) strategy in community low-threshold facilities for drug addiction and opioid agonist treatment (OAT) in high-threshold facilities for opioid addiction, focusing on pharmacological maintenance according to the Dole and Nyswander strategy. We aimed to compare the impact of HRT and OAT on patient outcome, as assessed through negativity for drugs on about 1-year urinalyses. Methods: We examined retrospectively the urinalyses of HRT and OAT patients for which at least four randomly sampled urinalyses per month were available for about 1 year, during which patients were undergoing methadone or buprenorphine maintenance; urinalyses focused on heroin, cocaine, cannabinoids, and their metabolites. Results: Included were 189 HRT and 58 OAT patients. The latter were observed for a significantly longer period. There was a higher proportion of heroin- and cocaine-clean urinalyses in OAT patients, with cocaine-clean urinalyses discriminating best between the two groups. OAT patients were older, with longer dependence duration, more severe addiction history, and received lower methadone doses. Buprenorphine maintenance was more often associated with heroin-clean urinalyses. The higher the methadone doses, the lower were the percentage of heroin-clean urinalyses in HRT patients (negative correlation). Conclusions: The OAT approach was related to higher recovery and polyabuse abstinence rates compared to the HRT approach, despite greater severity of substance use, psychiatric and physical comorbidities. Our results are consistent with the possibility to use lower maintenance opiate doses (after induction and stabilization in methadone treatment according to Dole and Nyswander methodology) in treating heroin addiction. This seemed to be impossible adopting the currently accepted HRT model

Remarkable Reduction of Cocaine Use in Dual Disorder (Adult Attention Deficit Hyperactive Disorder/Cocaine Use Disorder) Patients Treated with Medications for ADHD

Background: Cocaine use disorder (CUD) is a growing public health concern, but so far no effective pharmacotherapies have been demonstrated. Stimulant medications have proved to be promising in CUD treatment. The self-medication hypothesis (SMH) can help to explain this phenomenon better, especially in cases where CUD co-occurs with adult attention deficit hyperactivity disorder (A-ADHD). Methods: In the present retrospective study, a sample of 20 consecutive patients (aged from 18 to 65 years) with dual disorder (A-ADHD/CUD), under treatment with methylphenidate (MPH) or atomoxetine (ATM) medications, was followed to study the effects of A-ADHD treatment on cocaine use. Patients were followed for a mean period of 7 months (minimum 1, maximum 30 months). All individuals were assessed with standardized questionnaires to evaluate diagnosis, treatment efficacy, and clinical improvement. Results: the results showed that behaviors reflecting cocaine addiction were sharply reduced during the stimulant treatment of A-ADHD, and were not correlated with age, gender, familiarity, length of treatment, or medication used. CUD improvement was closely correlated with the A-ADHD improvement. This study supports the validity of the SMH in ADHD patients with co-occurring CUD

Can Ropinirole Modulate Reinforcing Subjective Effects of Cocaine in Humans?

In this study we evaluated, by means of the “cocaine rush visual analog scale,” the impact of ropinirole on the expected rush induced by cocaine in a group of heroin addicts abusing cocaine; the self-reported reaction to the rush blockade (if any) on cocaine consumption, and the correlations between this self-reported reaction and individual, clinical, and therapeutic parameters. Nineteen cocaine abuser heroin-dependent patients entered the study. Their experienced cocaine rush was 61.31 ± 32.1% of the maximum effect previously experienced. Compared with their previous rush intensity 16 patients experienced significantly lower intensity, 3 the same intensity, and none a higher intensity. In particular, two patients experienced a complete blockade of rush and reported a reduced use of cocaine. Fourteen patients experienced a partial blockade of cocaine rush; of these, nine reported they had reduced their use of cocaine. Ropinirole does diminish the subjective intensity of an expected cocaine rush, so interfering with the dynamics of reward, while supporting its possible use in the treatment of cocaine dependence

Contemporary perspective on addictive behaviors: underpinning mechanisms, assessment, and treatment

This special issue gathered contributions from authors in the scientifc community working on addictive behaviors. In particular, authors were solicited to relate about underpinning mechanisms, assessment protocols, and intervention programs that are currently proposed for substance abuse, Internet addiction, and other forms of problematic conducts in pediatric populations, adolescence, and adulthood. Most of the papers used a biopsychosocial model for the onset and maintaining of addictive behaviors and their comorbidities with other psychopathologies. Although the intent was accept contributions focused on all forms of addictive behaviors, this special issue is composed of four papers concerning problematic use of the web and two articles focusing on substance use. Of note, all papers addressed the developmental phases of childhood and adolescence

A wearable system to objectify assessment of motor tasks for supporting parkinson’s disease diagnosis

Objective assessment of the motor evaluation test for Parkinson’s disease (PD) diagnosis is an open issue both for clinical and technical experts since it could improve current clinical practice with benefits both for patients and healthcare systems. In this work, a wearable system composed of four inertial devices (two SensHand and two SensFoot), and related processing algorithms for extracting parameters from limbs motion was tested on 40 healthy subjects and 40 PD patients. Seventy-eight and 96 kinematic parameters were measured from lower and upper limbs, respectively. Statistical and correlation analysis allowed to define four datasets that were used to train and test five supervised learning classifiers. Excellent discrimination between the two groups was obtained with all the classifiers (average accuracy ranging from 0.936 to 0.960) and all the datasets (average accuracy ranging from 0.953 to 0.966), over three conditions that included parameters derived from lower, upper or all limbs. The best performances (accuracy = 1.00) were obtained when classifying all the limbs with linear support vector machine (SVM) or gaussian SVM. Even if further studies should be done, the current results are strongly promising to improve this system as a support tool for clinicians in objectifying PD diagnosis and monitoring

The mental status of 1090 heroin addicts at entry into treatment: should depression be considered a 'dual diagnosis'?

<p>Abstract</p> <p>Background</p> <p>Mental symptoms are common in heroin addiction and may arise from issues of addiction and withdrawal, raising doubts about the patients truly having co-morbid psychiatric diagnoses.</p> <p>Methods</p> <p>We studied the mental status of 1090 heroin addicts (831 males and 259 females aged between 16 and 51 years) at the beginning of treatment, and its relationship to relevant demographic and clinical data through the use of standardised instruments.</p> <p>Results</p> <p>A total of 506 (46.42%) heroin addicts showed depressive-anxious symptomatology, 421 (38.62%) had psychomotor excitement and 163 (14.95%) demonstrated a psychotic state. Patients with depressive-anxious symptomatology on the whole had a less severe addictive illness compared to those demonstrating excited and psychotic symptoms. The presence of depressive-anxious features was felt to not necessarily be indicative of the presence of a dual diagnosis.</p> <p>Conclusion</p> <p>The presence of depressive-anxious symptomatology in the clinical presentation in heroin addicts appears to be unrelated to 'dual diagnosis'.</p

Do Akiskal & Mallya's affective temperaments belong to the domain of pathology or to that of normality?

BACKGROUND: Kraepelin and Kretschmer hypothesized a continuum between full-blown affective pathology and premorbid temperaments. More recently Akiskal proposed a putative adaptive role for the four fundamental temperaments: the hyperthymic one characterized by emotional intensity, the cyclothymic one by emotional instability, the depressive one by a low energy level, and the irritable one by an excessive response to stimuli. Today it is widely debated whether affective temperaments belong to the domain of pathology or to that of normality. PURPOSE: To make clear, by applying an integrated model, the position of affective temperaments within the continuum between normality and pathology. METHODS: We reviewed several papers that explore the distribution of affective temperaments among the general population, and their involvement both in pathological conditions (somatic and psychiatric) and in human activities (professions and other occupations). RESULTS: Far from being intrinsically pathological conditions, affective temperaments seem to represent adaptive dispositions whose dysregulation can lead to full-blown affective pathology. All the temperamental types display some impact on people's lives by influencing personal skills and professional choices over a wide field of human activities. CONCLUSIONS: Affective temperaments are not problematic when they appear in a mild form, but when they occur in extreme form we have observed a gap between the hyperthymic temperament, which represents the most functional and desirable, and the cyclothymic, depressive, irritable and phobic anxious ones, which are closer to mood, anxiety, and substance use disorders, and imply a component of somatic diseases and life stressors

The effectiveness of the combination fluoxetine-naltrexone in bulimia nervosa.

Four patients with DSM-IV bulimia nervosa were treated in a crossover trial with naltrexone alone, fluoxetine alone, and a fluoxetine-naltrexone combination. Three patients presented a complete remission when treated with the fluoxetine-naltrexone combination
