RESUMO
The Evaluation of Therapeutic Community Treatments and Outcomes (VOECT) study was conducted in 131 Italian Therapeutic Communities (TCs) in 2008/2009. All of the patients entering residential treatment for drug or alcohol dependence were invited to participate. Data regarding patient socio-demographic characteristics, drug and alcohol consumption, health and psychopathological status, prior treatments and outcomes, and their motivation score were collected upon enrolment onto the study. The aim of this work was to identify the factors associated with allocation to short- versus long-term programmes in drug or alcohol dependent patients entering TCs in Italy. Of the 2470 patients included in the analysis, 30.8% were allocated to short-term treatment and 69.2% to long-term treatment. Several factors were significantly associated with the allocation to short- and long-term treatments: unstable living conditions; entering the TC when not detoxified; a high Symptom Checklist-90 somatization score; prior cessation episodes; previous in-patient detoxification treatments; psychosocial treatments; entering the TC by oneself; and a low motivation score.

BACKGROUND: Cocaine dependence is a major public health problem that is characterized by recidivism and a host of medical and psychosocial complications. Although effective pharmacotherapy is available for alcohol and heroin dependence none exists currently for cocaine dependence despite two decades of clinical trials primarily involving antidepressant, anti convulsivant and dopaminergic medications. There has been extensive consideration of optimal pharmacological approaches to the treatment of cocaine dependence with consideration of both dopamine antagonists and agonists. Anticonvulsants have been candidates for the treatment of addiction based on the hypothesis that seizure kindling-like mechanisms contribute to addiction. OBJECTIVES: To evaluate the efficacy and the acceptability of anticonvulsants for cocaine dependence SEARCH STRATEGY: We searched the Cochrane Drugs and Alcohol Groups specialised register (issue 4, 2007), MEDLINE (1966 - march 2007), EMBASE (1988 - march 2007), CINAHL (1982- to march 2007) SELECTION CRITERIA: All randomised controlled trials and controlled clinical trials which focus on the use of anticonvulsants medication for cocaine dependence DATA COLLECTION AND ANALYSIS: Two authors independently evaluated the papers, extracted data, rated methodological quality MAIN RESULTS: Fifteen studies (1066 participants) met the inclusion criteria for this review: the anticonvulsants drugs studied were carbamazepine, gabapentin, lamotrigine, phenytoin, tiagabine, topiramate, valproate. No significant differences were found for any of the efficacy measures comparing any anticonvulsants with placebo. Placebo was found to be superior to gabapentin in diminishing the number of dropouts, two studies, 81 participants, Relative Risk (RR) 3.56 (95% CI 1.07 to 11.82) and superior to phenythoin for side effects, two studies, 56 participants RR 2.12 (95% CI 1.08 to 4.17). All the other single comparisons are not statistically significant. AUTHORS' CONCLUSIONS: Although caution is needed when assessing results from a limited number of small clinical trials at present there is no current evidence supporting the clinical use of anticonvulsants medications in the treatment of cocaine dependence. Aiming to answer the urgent demand of clinicians, patients, families, and the community as a whole for an adequate treatment for cocaine dependence, we need to improve the primary research in the field of addictions in order to make the best possible use out of a single study and to investigate the efficacy of other pharmacological agent.

BACKGROUND: Cocaine dependence is a public health problem characterized by recidivism and a host of medical and psychosocial complications. Cocaine dependence remains a disorder for which no pharmacological treatment of proven efficacy exists, although considerable advances in the neurobiology of this addiction could guide future medication development OBJECTIVES: To evaluate the efficacy and the acceptability of antipsychotic medications for cocaine dependence SEARCH STRATEGY: We searched the following sources: MEDLINE (1966 to October 2006), EMBASE (1980 to October 2006), CINAHL (1982 to October 2006), Cochrane Drug and Alcohol Group Specialised Register (October 2006). We also searched the reference lists of trials, the main electronic sources of ongoing trials (National Research Register, meta-Register of Controlled Trials; Clinical Trials.gov) and conference proceedings likely to contain trials relevant to the review. All searches included also non-English language literature. SELECTION CRITERIA: All randomised controlled trials and controlled clinical trials with focus on the use of any antipsychotic medication for cocaine dependence DATA COLLECTION AND ANALYSIS: Two authors independently evaluated the papers, extracted data, rated methodological quality MAIN RESULTS: Seven small studies were included (293 participants): the antipsychotic drugs studied were risperidone, olanzapine and haloperidol. No significant differences were found for any of the efficacy measures comparing any antipsychotic with placebo. Risperidone was found to be superior to placebo in diminishing the number of dropouts, four studies, 178 participants, Relative Risk (RR) 0.77 (95% CI 0.77 to 0.98). Most of the included studies did not report useful results on important outcomes such as side effects, use of cocaine during treatment and craving. The results on olanzapine and haloperidol come from studies too small to give conclusive results. AUTHORS' CONCLUSIONS: Although caution is needed when assessing results from a limited number of small clinical trials there is no current evidence, at the present , supporting the clinical use of antipsychotic medications in the treatment of cocaine dependence. Furthermore, most of the included studies did not report useful results on important outcomes such as side effects, use of cocaine during the treatment and craving. Aiming to answer the urgent demand of clinicians, patients, families, and the community as a whole for an adequate treatment for cocaine dependence, larger randomised investigations should be designed investigating relevant outcomes and reporting data to allow comparison of results between studies. Moreover some efforts should be done also to investigate the efficacy of other type medications, like anticonvulsant, currently used in clinical practice.

Clinical trials carried out to compare methadone and buprenorphine in the treatment of opioid dependence have generally employed an alcoholic solution of buprenorphine, which has a bioavailability superior to that of the tablets. Since the product available for large scale use is in tablet form, one intended to verify the efficacy of this formulation. In a multicentre randomised controlled double blind study, 72 opioid dependent patients were assigned to treatment with buprenorphine (8 mg/day) or methadone (60 mg/day) for a period of 6 months. The two compounds did not show any significant difference with regard to urinalyses: the average percentage of analyses proving negative was 60.4% for patients assigned to buprenorphine, and 65.5% for those assigned to methadone. With regard to retention, a non-significant trend in favour of methadone was observed. Patients completing the trial improved significantly in terms of psychosocial adjustment and global functioning, as ascertained by the DSM-IV-GAF and symptom checklist-90 (SCL-90) scales, and this was independent of the treatment group. Finally, in the case of buprenorphine, patients who dropped out differed significantly from those who stayed, in terms of a higher level of psychopathological symptoms, and a lower level of psychosocial functioning. The results of the study further support the utility of buprenorphine for the treatment of opioid dependence.

The purpose of this study was to investigate the influence of the severity of concomitant psychiatric symptomatology on some selected measures of methadone maintenance treatment efficacy in a comprehensive methadone maintenance treatment program (MMTP). The cohort studied included 267 patients who entered a maintenance program in the years 1991-92. Two groups of patients differing in the severity of psychiatric symptomatology were obtained on the bases of the referral to the psychiatrist and the ascertainment of a current disorder. These two groups were compared for retention in treatment, urine tests positive for morphine while in treatment and methadone dose during an observation period of 2 years. The outcome of the study suggests that on these outcome parameters, patients on MMTP who are more psychiatrically ill can perform as well as the other patients.

Patients on methadone maintenance were forewarned that a law prohibiting take-home dosages was to be enforced within 6 months. At the end of the 6-month period preceding the enforcement of the law the effect of the anticipated suppression of the take-home privilege was studied on a cohort of 211 methadone-maintained patients on take-home dosages. The outcome of the treatment of these patients was compared to that of a control group of 220 patients at the end of a 6-month period prior to the announcement of the new law. The outcome of the study suggests that the restrictive regulation is counterproductive for retaining patients in treatment.

In a double-blind placebo-controlled trial, gamma-hydroxybutyric acid (GHB) (25 mg/kg orally) suppressed most of the withdrawal symptomatology in 14 heroin addicts and 13 methadone-maintained subjects. The GHB effect was prompt (within 15 minutes) and persisted for between 2 and 3 hours. Subsequently, the same patients received GHB in an open study every 2 to 4 hours for the first 2 days and 4 to 6 hours for the following 6 days: most abstinence signs and symptoms remained suppressed and patients reported felling well. Urine analysis failed to detect any presence of opiate metabolites. No withdrawal symptomatology recurred after 8 days of treatment when GHB was suspended, and patients were challenged with an intravenous injection of 0.4 mg naloxone. The results indicate that GHB may be useful in the management of opiate withdrawal.

The aim of the study was to assess the presence and nature of psychiatric disorders in opium drug addicts. One hundred and six subjects receiving treatment at the CMAS in Cagliari were included in the study. Hathawai and McKinley's MMPI test was preventively carried out on all subjects; each drug addict was then interviewed three times in the space of three weeks in order to formulate a diagnosis in line with DSM III R criteria. The results obtained show a high incidence of psychopathological disorders which are not included among those caused by drug abuse, and a high degree of diagnostic heterogeneity on both axis I and axis II. The comparative assessment of three subsamples undergoing different phases of treatment reveals both qualitative and quantitative differences.
