Pharmacological interventions for benzodiazepine mono-dependence management in outpatient settings.

BACKGROUND: The improved safety profile of benzodiazepines compared to barbiturates has contributed to a high rate of prescription since the seventies. Although benzodiazepines are highly effective for some disorders, they are potentially addictive drugs and they can provide reinforcement in some individuals. OBJECTIVES: To evaluate the effectiveness of pharmacological interventions for benzodiazepine mono-dependence. SEARCH STRATEGY: We searched the Cochrane Drugs and Alcohol Group' Register of Trials (October 2004), the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library Issue 4, 2004), MEDLINE (January 1966 to October 2004), EMBASE (January 1988 to October 2004), PsycInfo (1985 to October 2004), CINAHL (1982 to October 2004), Pascal, Toxibase, reference lists of articles. SELECTION CRITERIA: Randomized trials of benzodiazepines dependence management regardless of type, dose (daily and total) and duration of benzodiazepine treatment. DATA COLLECTION AND ANALYSIS: Reviewers independently assessed trials for inclusion, rated their methodological quality and extracted data. MAIN RESULTS: Eight trials involving 458 participants were included. The studies included could not be analysed cumulatively because of heterogeneity of inteventions and participants' characteristics. Results support the policy of gradual rather than abrupt withdrawal of benzodiazepine. Progressive withdrawal (over 10 weeks) appeared preferable if compared to abrupt since the number of drop-outs was less important and the procedure judged more favourable by the participants. Short half-life benzodiazepine, associated with higher drop-out rates, did not have higher withdrawal symptoms scores. Switching from short half-life benzodiazepine to long half-life benzodiazepine before gradual taper withdrawal did not receive much support from this review. The role of propanolol in benzodiazepine withdrawal was unclear; adding tricyclic antidepressant (dothiepin) decreased the intensity of withdrawal symptoms but did not increase the rate of benzodiazepine abstinence at the end of the trial. Buspirone and Progesterone failed to suppress any benzodiazepine symptoms. Carbamazepine might have promise as an adjunctive medication for benzodiazepine withdrawal, particularly in patients receiving benzodiazepines in daily dosages of 20 mg/d or more of diazepam (or equivalents). AUTHORS' CONCLUSIONS: The results of this systematic review point to the potential value of carbamazepine as an effective intervention for benzodiazepine gradual taper discontinuation. Carbamazepine has shown rather modest benefit in reducing withdrawal severity, although it did significantly improve drug-free outcome. Larger controlled studies are needed to confirm these benefits, to assess adverse effects and to identify when its clinical use might be most indicated. Other suggested treatment approaches to benzodiazepine discontinuation management should be explored (antidepressants, benzodiazepine receptors modulator).

Psychotherapeutic interventions for cannabis abuse and/or dependence in outpatient settings.

BACKGROUND: Cannabis use disorder is the most common illicit substance use disorder in general population. Despite that, only a minority seek assistance from a health professional, but the demand for treatment is now increasing internationally. Trials of treatment have been published but to our knowledge, there is no published systematic review . OBJECTIVES: To evaluate the efficacy of psychosocial interventions for cannabis abuse or dependence. SEARCH STRATEGY: We searched the Cochrane Central Register of Trials (CENTRAL) The Cochrane Library Issue 3, 2004; MEDLINE (January 1966 to August 2004), PsycInfo (1985 to October 2004), CINAHL (1982 to October 2004), Toxibase (until September 2004) and reference lists of articles. We also contacted researchers in the field. SELECTION CRITERIA: All randomized controlled studies examining a psychotherapeutic intervention for cannabis dependence or abuse in comparison with a delayed-treatment control group or combinations of psychotherapeutic interventions. DATA COLLECTION AND ANALYSIS: Two authors independently assessed trial quality and extracted data MAIN RESULTS: Six trials involving 1297 people were included. Five studies took place in the United States, one in Australia. Studies were not pooled in meta-analysis because of heterogeneity. The six included studies suggested that counseling approaches might have beneficial effects for the treatment of cannabis dependence. Group and individual sessions of cognitive behavioral therapy (CBT) had both efficacy for the treatment of cannabis dependence and associated problems, CBT produced better outcomes than a brief intervention when CBT was delivered in individual sessions. Two studies suggested that adding voucher-based incentives may enhance treatment when used in combination with other effective psychotherapeutic interventions. Abstinence rates were relatively small overall but favored the individual CBT 9-session (or more) condition. All included trials reported a statistically significant reductions in frequency of cannabis use and dependence symptoms. But other measures of problems related to cannabis use were not consistently different. AUTHORS' CONCLUSIONS: The included studies were too heterogenous and could not allow to draw up a clear conclusion. The studies comparing different therapeutic modalities raise important questions about the duration, intensity and type of treatment. The generalizability of findings is also unknown because the studies have been conducted in a limited number of localities with fairly homogenous samples of treatment seekers. However, the low abstinence rate indicated that cannabis dependence is not easily treated by psychotherapies in outpatient settings.

Examining the influence of drop-outs in a follow-up of maintained opiate users.

INTRODUCTION: In most longitudinal studies of problem opiate users, drop-outs are frequent, but not taken into account. However, missing data can induce important bias in parameters estimates. OBJECTIVE: The aim of this study was to examine the influence of drop-outs in the statistical analysis of a follow-up of opiate users in maintenance treatment. METHODS: Participants were 519 patients who had sought maintenance treatment between 1994 and 2001. Drug use was studied using the drug composite score of the Addiction Severity Index. A classical data analysis (linear mixed effects model for repeated measurements) was compared with a selection model, which consists, in this case, of a joint modelling of the score and of the drop-out probability in order to reduce bias induced by drop-outs. RESULTS: At 18 months, 38% of the patients were available for evaluation. Drop-outs were associated with low drug use and were informative. Each model showed that the score decreased over time and that it was associated with psychiatric problems. Unlike the classical method, the joint model showed no significant association between the score and age or treatment setting. CONCLUSIONS: These results show the importance of accounting for informative drop-outs in data analysis before drawing conclusions from such studies.

Sensation seeking as a common factor in opioid dependent subjects and high risk sport practicing subjects. A cross sectional study.

OBJECTIVE: Animal research has outlined a vulnerability trait to drug dependence like behavior. The behavioral characteristic of this vulnerability is hyperactivity in response to a novel environment of which sensation seeking (SS) has been suggested as a possible equivalent in humans. If this is the case, SS should be more frequent in drug dependent and risky sports practicing subjects then controls. The objective of this study was to determine if opioid dependent subjects (ODS) and regular paragliders (RP) would be more SS then normal controls. DESIGN: Cross sectional study. PARTICIPANTS: Three groups of 34 individuals (total 102) matched for age and sex were selected from ODS seeking treatment, a paragliding club, and a college staff. MAIN OUTCOME MEASURES: Global and sub-scores of the Zuckerman sensation seeking scale (SSS). RESULTS: Non parametric statistics (Kruskal Wallis and Wilcoxon 2-Sample Tests) were used given the non-normal distribution of SSS scores in the ODS and RP groups. Significant differences were found across the three groups for the Thrill and Adventure Seeking (TAS) (P = 0.001), dishinibition (Dis) (P = 0.0003) and total score (P = 0.001). ODS and RP scored significantly higher than controls on two (Dis and the TAS scales). RP also scored significantly higher on the Boredom Susceptibility (BS) scale (P = 0.04). CONCLUSION: Our results show that RP and ODS differ from controls and have some similarities based on the SSS. In this study, the ODS and the RP could express different forms of a general tendency to seek intense and abrupt sensations through various behaviors. Our results in humans are in favor of the hypothesis that the behavioral trait of vulnerability to drug dependence behavior is expressed through SS.

[Sports, use of performance enhancing drugs and addiction. A conceptual and epidemiological review].

BACKGROUND: Both the general public and non-sports medicine health professionals have recently been made aware of a large use of performance enhancing drugs among sports practicing subjects. It has been suggested that this behavior is similar to that of substance dependence. Also some have reported that practice of a sport could be in itself an addictive behavior. OBJECTIVE: The main objective was to address the following question: is performance enhancing drug use in sports an addictive behavior? Methodology. We first reviewed the definition of performance enhancing drug use in sports and the diagnostic criteria of substance dependence as they are currently accepted and attempted to determine a possible common factor. Secondly we reviewed epidemiological data from the literature according to three approaches: RESULTS: Use of performance enhancing drugs is an important and increasing phenomenon among adolescents. It is sometimes associated to risk taking behaviors for health (syringe use and sharing). Competition participants are at increased risk (up to 20% according to some authors) and some substances (anabolic steroids) are also used by non-sports practicing individuals. It has not been shown that sports practicing subjects were more at risk of using addictive substances compared to non-sports practicing subjects. It is not established that practice of a sport is by itself a risk factor for substance use. However, it could be that a sub-group of individuals that practice certain types of sports in an intensive way, that use both performance enhancing drugs and addictive substances and that engage in health risk taking behaviors have an increased risk for developing a dependence syndrome to both addictive and performance enhancing drugs. This sub-group is even more at risk because some performance enhancing drugs (anabolic steroids) could increase the risk for occurrence of a substance dependence syndrome through neurobiological actions. Yet, the few available clinical studies show that at most only half of regular users actually meet criteria for dependence. Also, one study has reported an overrepresentation of sports professionals among patients seeking treatment for heroin addiction. CONCLUSION: The large majority of sports practicing subjects have no dependence to either performance enhancing or addictive drugs. However, a subgroup of individuals that practice sports intensely and makes use of both addictive and performance enhancing drugs appear to be at increased risk for developing a substance dependence syndrome.

Post-ECT agitation and plasma lactate concentrations.

This prospective study evaluated the hypothesis that emergence agitation after electroconvulsive therapy (ECT) could be caused by lactate-induced panic secondary to insufficient neuromuscular blockade. Plasma lactate levels were measured before and after 245 consecutive ECT sessions in 37 patients monitored for evidence of post-ECT agitation. ECT was administered using a brief-pulse, rectangular, constant-current device through bilaterally placed electrodes under general anesthesia and neuromuscular blockade. Agitation was observed in 7% of all ECT sessions. No significant difference could be found in pre-ECT lactate levels. However, mean post-ECT lactate levels in agitated sessions were significantly greater than those in nonagitated sessions (4.77 versus 2.54 mmol/l, p < 0.05). An increase (+27%) in the pre-ECT succinylcholine dose for those patients who previously had repeated post-ECT agitation resulted in cessation of post-ECT agitation and return of the formerly high post-ECT lactate levels to normal (1.61 versus 2.07 mmol/l). Although the number of patients who had post-ECT agitation was small, the data support the hypothesis that post-ECT agitation might be a manifestation of lactate-induced panic.

[Evaluation of the use of psychotropic drugs from urine samples from subjects attending for the first time a clinic specializing in opium addiction].

OBJECTIVES: Determine how well drug abusers requesting care accept urine sampling and the reliability of this method for evaluating drug use. METHODS: Subjects attending a specialized drug abuse clinic for the first time were requested to provide a urine sample for semiquantitative analysis using an immunological technique to identify the following substances: barbiturates, benzodiazepines, opiates, cocaine, amphetamines, cannabis, and dextropropoxyphen. RESULTS: All 98 subjects included in the study accepted the urine sample. More than 80% of the samples were positive for 1, 2 or 3 substances. The most frequent were, in decreasing order, opiates, cannabis, benzodiazepines and dextropropoxyphen. Among the opiate-positive subjects (70%), 80% were positive for 2 other substances, usually cannabis and benzodiazepines. Two-thirds of the cocaine-positive cases were observed among the most recently seen subjects. Among the 27 opiate-negative subjects, 16 stated they used buprenorphine. CONCLUSION: Within the setting of this study, urine sampling appeared to be well accepted by drug abusers. Urinalysis gave an objective evaluation of drug use and can be useful on an individual level providing complementary information to the overall examination. Urine sampling can also provide indicators for studying the evolution of drug use practices in different populations, both in a clinical and non-clinical setting.

[Withdrawal and management of opiate addicts].

The first goal of addiction treatment is to enable the patient to withdraw in a medically controlled environment. Medically assisted withdrawal is a specific treatment of pharmacological dependence. Different methods of treatment are used, specific and non-specific. Clonidine and transcutaneous electrostimulation with Limoge current are the only relatively specific treatment modalities. However, whichever method is used, relapse is frequent and patients are not easily admitted for treatment. Noteworthy is the fact that anticipatory anxiety is a major predictor of treatment compliance and should be looked for. The goal for the best detoxification treatment should give way to opiate agonist maintenance treatment when relapse is too frequent.

A randomized double-blind study of neuroelectric therapy in opiate and cocaine detoxification.

Prior research on the use of transcranial neuroelectric stimulation suggested that the application of low-amperage, low-frequency alternating current via surface electrodes placed in the mastoid region could relieve the physiological signs and subjective symptoms of withdrawal and craving during opiate detoxification. These effects were reported without gradual tapering of the opiate or the addition of other medications. To test the efficacy of one particular form of neuroelectric therapy (NET), a double-blind, randomized, placebo-controlled study was conducted comparing active NET and placebo NET in the treatment of withdrawal and stabilization of 18 opiate-dependent and 25 cocaine-dependent subjects. Scores on scales for measuring substance withdrawal and craving for each abused substance, as well as the multiple dimensions of mood, were compared for degree of difference across the 10 days of treatment. There was an overall completion rate of 88%, with both cocaine and opiate groups reporting a comfortable detoxification and substantial improvement over the course of a 12-day hospitalization. There was no significant difference between the active or placebo groups, suggesting that placebo was as effective as active NET in reducing drug withdrawal or craving during cocaine and opiate detoxification. However, all placebo patients received 0.2 mA of current, which may have provided a degree of active current. Suggestions are offered for future research.
