RESUMEN
BACKGROUND: For the emerging DSM-V, it has been recommended that dimensional and categorical methods be used simultaneously in diagnostic classification; however, little is known about this combined approach for abuse and dependence. METHOD: Using data (n=37 708) from the 2007 National Survey on Drug Use and Health (NSDUH), DSM-IV criteria for prescription opioid abuse and dependence among non-prescribed opioid users (n=3037) were examined using factor analysis (FA), latent class analysis (LCA, categorical), item response theory (IRT, dimensional), and factor mixture (hybrid) approaches. RESULTS: A two-class factor mixture model (FMM) combining features of categorical latent classes and dimensional IRT estimates empirically fitted more parsimoniously to abuse and dependence criteria data than models from FA, LCA and IRT procedures respectively. This mixture model included a severely affected group (7%) with a comparatively moderate to high probability (0.32-0.88) of endorsing all abuse and dependence criteria items, and a less severely affected group (93%) with a low probability (0.003-0.16) of endorsing all criteria. The two empirically defined groups differed significantly in the pattern of non-prescribed opioid use, co-morbid major depression, and substance abuse treatment use. CONCLUSIONS: A factor mixture model integrating categorical and dimensional features of classification fits better to DSM-IV criteria for prescription opioid abuse and dependence in adults than a categorical or dimensional approach. Research is needed to examine the utility of this mixture classification for substance use disorders and treatment response.

The Russian health care system is organized around specific diseases, with relatively little focus on integration across specialties to address co-morbidities. This organizational structure presents new challenges in the context of the recent epidemics of injection drug use (IDU) and HIV. This paper uses existing and new data to examine the prevalence of reported new cases of drug dependence (heroin) and HIV over time as well as associations between drug dependence and alcoholism, hepatitis B and C, and tuberculosis in the City of St. Petersburg and the Leningrad region. We found a sharp rise in reported cases of IDU beginning in 1991 and continuing until 2002/2003, followed by a sharp rise in newly reported cases of HIV. These rises were followed by a drop in new cases of HIV and drug addiction in 2002/2003 and a drop in the proportion of HIV-positive individuals with IDU as a risk factor. Infection with hepatitis B and C were common, especially among injection drug users (38 and 85%, respectively), but also in alcoholics (7 and 14%). Tuberculosis was more common in alcoholics (53%) than in persons with alcoholism and drug dependence (10%), or with drug dependence alone (4%). Though these data have many limitations, they clearly demonstrate that drug dependence and/or alcoholism, HIV, hepatitis, and tuberculosis frequently co-occur in St. Petersburg and the Leningrad Region. Prevention and treatment services across medical specialties should be integrated to address the wide range of issues that are associated with these co-morbidities.

OBJECTIVE: Compare substance use among men who have sex with men (MSM) at high risk for HIV infection to a nationally representative sample of heterosexual men. METHODS: Compare data from surveys of 3,212 MSM recruited for participation in a Vaccine Preparedness Study (VPS) with an age-standardized group of 2481 single, urban-dwelling men from the 1995 National Household Survey on Drug Abuse (NHSDA). RESULTS: Except for alcohol, relative risk (RR [95% confidence interval (CI)]) for use of any substance was higher in the VPS than the National Household Survey on Drug Abuse (NHSDA) (3.64 [3.01-4.42]). Drugs with the highest relative risks were "poppers" (21.6 [15.2-30.8]), sedatives (6.98 [2.46-19.8]), hallucinogens (6.14 [4.61-8.17]), tranquilizers (4.99 [2.96-8.42]), and stimulants (4.47 [3.58-5.58]). RR was higher for weekly use of poppers (33.5 [12.5-89.6]), stimulants (2.75 [1.79-4.22]), marijuana (2.37 [1.93-2.92]), and cocaine (2.24 [1.32-3.79]); and for daily use of marijuana (1.49 [1.08-2.05]). CONCLUSIONS: Participants in the VPS used more substances than a group of age-standardized, single, urban-dwelling men from the NHSDA. In view of previous data showing that substance use can be associated with unprotected sex, assessing substance use among MSM at high risk for HIV infection is an important component of risk reduction efforts.

This study documents the costs of heroin addiction in the United States, both to the addict and society at large. Using a cost-of-illness approach, costs were estimated in four broad areas: medical care, lost productivity, crime, and social welfare. We estimate that the cost of heroin addiction in the United States was US$21.9 billion in 1996. Of these costs, productivity losses accounted for approximately US$11.5 billion (53%), criminal activities US$5.2 billion (24%), medical care US$5.0 billion (23%), and social welfare US$0.1 billion (0.5%). The large economic burden resulting from heroin addiction highlights the importance of investment in prevention and treatment.

BACKGROUND: This was a multicenter investigation examining the efficacy of 4 psychosocial treatments for cocaine-dependent patients. METHODS: Four hundred eighty-seven patients were randomly assigned to 1 of 4 manual-guided treatments: individual drug counseling plus group drug counseling (GDC), cognitive therapy plus GDC, supportive-expressive therapy plus GDC, or GDC alone. Treatment was intensive, including 36 possible individual sessions and 24 group sessions for 6 months. Patients were assessed monthly during active treatment and at 9 and 12 months after baseline. Primary outcome measures were the Addiction Severity Index-Drug Use Composite score and the number of days of cocaine use in the past month. RESULTS: Compared with the 2 psychotherapies and with GDC alone, individual drug counseling plus GDC showed the greatest improvement on the Addiction Severity Index-Drug Use Composite score. Individual group counseling plus GDC was also superior to the 2 psychotherapies on the number of days of cocaine use in the past month. Hypotheses regarding the superiority of psychotherapy to GDC for patients with greater psychiatric severity and the superiority of cognitive therapy plus GDC compared with supportive-expressive therapy plus GDC for patients with antisocial personality traits or external coping style were not confirmed. CONCLUSION: Compared with professional psychotherapy, a manual-guided combination of intensive individual drug counseling and GDC has promise for the treatment of cocaine dependence.

Condom failure (slippage or breakage) has been shown to be associated with HIV seroconversion among men who have sex with men (MSM), but predictors of failure have been poorly elucidated. Of 2592 HIV-seronegative MSM participants in the HIV Network for Prevention Trials (HIVNET) multisite Vaccine Preparedness Study who reported condom use for anal sex in the 6 months before enrollment, condom failure was reported by 16.6%, with failure rates of 2.1/100 episodes of condom usage (2.5 failures/100 episodes for receptive anal sex and 1.9/100 episodes for insertive anal sex). In separate multivariate models evaluating predictors of condom failure reported by the insertive and receptive partners, more frequent condom use was associated with a decreased per-condom failure rate and amphetamine and heavy alcohol use with increased rates in both models. Being employed, having private medical insurance, and using lubricants for >80% of anal sex acts were significantly associated with decreased failure rates in the insertive model. Safer sex counseling should particularly target men of lower socioeconomic status, promote proper and consistent use of condoms with appropriate lubricants, and address the impact of drug use, especially amphetamines and alcohol, on condom failure.
PIP: Although the extent of condom use during anal intercourse has increased considerably among men who have sex with men (MSM) in response to the HIV/AIDS pandemic, condom failure through both slippage and breakage limits the effectiveness of such method use. Condom failure is associated with HIV seroconversion among MSM. 16.6% of the 2592 HIV-seronegative MSM participants in the HIV Network for Prevention Trials (HIVNET) multi-site Vaccine Preparedness Study who reported condom use for anal sex in the 6 months before enrollment reported condom failure. The overall failure rate was 2.1/100 episodes of condom use, with 2.5 failures/100 episodes for receptive anal sex and 1.9/100 episodes for insertive anal sex. Almost half of the men were aged 30 years or younger, 25% were non-White, 60.6% attended college, and 85.7% were employed either part- or full-time. Multivariate analysis of reported failures found more frequent condom use to be associated with a decreased per condom failure rate, and amphetamine and heavy alcohol use with increased rates in both models. Being employed, having private medical insurance, and using lubricants for more than 80% of anal sex acts were significantly associated with decreased failure rates in the insertive model. These findings suggest that safer sex counseling should therefore target men of lower socioeconomic status, promote the proper and consistent use of condoms with appropriate lubricants, and address the impact of drug use upon condom failure.

The role of exercise and sport in the lives of intravenous drug users (n = 45) was assessed, using an interviewer-administered open-ended questionnaire. Results demonstrated a high level of exercise and sport interest in this population (64%). Being a sports fan was also found in most of the responses (72%). This study on the role of exercise and sport in an intravenous drug-using population could be considered when developing rehabilitation measures or as an addition to present therapeutic interventions.

Associations between substance use and sexual behavior were examined among 3220 seronegative men who have sex with men (MSM) in a HIV vaccine preparedness study. Relationships between current and past substance use and current sexual risk were evaluated using crude odds ratios and logistic regression to adjust for confounding variables. Heroin and injection drug use were uncommon (< 2%). Substances most often used were alcohol (89%), marijuana (49%), nitrite inhalants (29%), amphetamines or similarly acting stimulants (21%), cocaine 14% and hallucinogens (14%). Increased adjusted odds for unprotected sex were significantly associated with current heavy alcohol use (OR 1.66; CI 1.18, 2.33), past alcohol problems (OR 1.25; CI 1.05, 1.48), and current drug use (OR 1.26; CI 1.08, 1.48). When associations with specific drugs and nitrite inhalants were examined separately, current use of cocaine and other stimulants (OR 1.25; CI 1.01, 1.55), hallucinogens (OR 1.40; CI 1.10, 1.77), and nitrite inhalants (some (OR 1.61; CI 1.35, 1.92); heavy (OR 2.18; CI 1.48, 3.20)), were independently associated with unprotected sex. Those with past drug use or past heavy alcohol use but not currently using demonstrated no increase in sexual risk, suggesting an important role for substance-focused interventions in risk reduction efforts among MSM.

Tramadol HCl, marketed as Ultram in the USA, was introduced as a non-scheduled drug in April 1995 based on the assumption that the risk of abuse was sufficiently low to warrant a non-scheduled status. However, approval was contingent upon the development of an innovative proactive surveillance program, to be overseen by an independent steering committee, which would detect unexpectedly high levels of abuse. The postmarketing surveillance program consisted of systematic collection and scientific evaluation of reports of suspected abuse in high-risk populations surveyed through an extensive key informant network of drug abuse specialists and all spontaneous reports of abuse received through the FDA MedWatch system. Methods to estimate the number of patients prescribed tramadol were also developed. Monthly rates of abuse were calculated as an index of the risk-benefit ratio (i.e., abuse cases per 100,000 patients prescribed the drug). The data for the 3 years since the drug was introduced show that the reported rate of abuse has been low. Although a period of experimentation seemed to occur in the first 18 months after its introduction--which reached a peak rate of approximately two cases per 100,000 patients exposed--during the 2 year period prior to June 1998, the reported rate of abuse has significantly (P = 0.011) declined, reaching levels of less than one case per 100,000 patients in the last 18 months. The overwhelming majority of abuse cases (97%) have been found to occur among individuals with a history of substance abuse and the abuse has been confined to isolated pockets around the country-notably none of which have significant populations of street drug abusers. Thus, the data support the decision not to schedule tramadol and, furthermore, suggest that a proactive post-marketing surveillance program can be successfully developed to effectively monitor abuse of new medications.

OBJECTIVES: Mortality among 507 patients in a methadone program over a 1-year period was assessed. METHODS: Mortality was determined for patients in treatment (n = 397), and 12 months later for those discharged (n = 110). RESULTS: Of discharged patients, 8.2% (9/110) had died, of which six were caused by heroin overdose. None of the discharged clients were in treatment at the time of death. All deaths were among clients who either dropped out of treatment or were discharged unfavorably from the program. Comparatively, only 1% (4/397) of patients died while enrolled in treatment. CONCLUSION: Death rates, especially overdose, are high among patients who are unfavorably discharged or drop out of methadone treatment. Efforts should be made to retain these at-risk patients in methadone treatment even though treatment response may be suboptimal.

OBJECTIVE: As the acquired immunodeficiency syndrome (AIDS) epidemic among drug users enters its third decade in the United States, it is important to consider the role playing by substance abuse treatment in the prevention of human immunodeficiency virus (HIV) infection. METHODS: The authors review the research literature, examining findings from studies with behavioral and serologic measures on the association among treatment participation, HIV risk reduction, and HIV infection. RESULTS: Numerous studies have now documented that significantly lower rates of drug use and related risk behaviors are practiced by injecting drug users (IDUs) who are in treatment. Importantly, these behavioral differences, based primarily on self-report, are consistent with studies that have examined HIV seroprevalence and seroincidence among drug users. CONCLUSION: The underlying mechanism of action suggested by the collective findings of the available literature is rather simple-- individuals who enter and remain in treatment reduce their drug use, when leads to fewer instances of drug-related risk behavior. This lower rate of exposure results in fewer infections with HIV. The protective effects of treatment, however, can only be achieved when programs are accessible and responsive to the changing needs of drug users. Future research needs to be directed at developing a better understanding of the factors that enhance treatment entry and retention.

BACKGROUND: Home human immunodeficiency virus (HIV) testing has been proposed as an alternative to conventional HIV testing. Despite debate over HIV type 1 (HIV-1) home test systems, these concerns have not to our knowledge been previously studied. OBJECTIVE: To evaluate the safety and efficacy of the Home Access Health Corp (Hoffman Estates, Ill) HIV-1 test system compared with traditional HIV-1 testing with venous blood. METHODS: A total of 1255 subjects were studied prospectively in a blinded, subject-as-control evaluation at 9 outpatient clinics using intent-to-treat analysis. Subjects were provided a home collection kit (Home Access Health Corp) to collect their own finger-stick blood spot samples for laboratory analysis. Subjects received pretest counseling by telephone and their comprehension was subsequently assessed. Subject-collected blood spot samples were compared with professionally drawn blood spot samples for adequacy (sufficient for completing the Food and Drug Administration-endorsed testing) and with venous samples for accuracy. Subjects called 3 days later for anonymous results and posttest counseling. Device safety was evaluated based on adverse events incidence. Subject comprehension of HIV information was measured. RESULTS: Subject-collected blood spot sample results were in complete agreement with venous blood sample results, demonstrating 100% sensitivity and 100% specificity compared with venous controls. Ninety-eight percent of subjects obtained testable blood spot specimens compared with phlebotomists. Following pretest counseling, subjects answered 96% of HIV risk questions correctly. There were no significant adverse events. CONCLUSION: Anonymous HIV-1 home collection kits with pretest and posttest telephone counseling can provide a safe and effective alternative to conventional venous HIV-1 antibody testing.

These data are internally consistent and lead to several conclusions, as follows: Elevated levels of psychiatric symptoms were found among IDUs in methadone treatment as compared to their counterparts who were out of treatment. IVDUs who entered treatment had higher symptom levels than those who did not enter treatment. Higher symptom levels were found among injectors than noninjectors, and needle sharers had especially high psychiatric symptom levels. Higher symptom levels were found among those who seroconverted in the 6 months following notification, but not thereafter. Symptom levels did not distinguish between HIV-positive and HIV-negative individuals 24 months following notification of seropositivity. Taken together, these findings indicate that elevated psychiatric symptoms are risk factors for continued high risk behavior, as well as for seroconversion. The data add to those of Brooner and colleagues (1993), who demonstrated that ASPD serves as a risk factor for HIV infection. The fact that antisocial personality disorder and psychiatric severity are associated with risky behavior and with actual HIV infection further expands earlier findings showing that these two factors are associated with poorer treatment outcome. Other axis II disorders (e.g., borderline or narcissistic), as well as other axis I disorders with high symptom levels that were not well represented in these studies (schizophrenia, manic depressive illness), may also show similar elevated rates of risky behavior and seroconversion, although there is a scarcity of data currently available to assess the risk behavior of these patients. The evidence from treatment studies that psychiatrically focused therapies, when combined with substance abuse treatment, can improve overall outcome for patients with clinically significant levels of psychiatric symptoms may be relevant in the design of future risk reduction efforts. That is, these treatment outcome studies may serve as a starting point for exploring the feasibility and efficacy of using psychiatrically focused treatment to reduce risky behavior and HIV infection among psychiatrically symptomatic IDUs.

Federal probationers or parolees with a history of opioid addiction were referred by themselves or their probation/parole officer for a naltrexone treatment study. Participation was voluntary and subjects could drop out of the study at any time without adverse consequences. Following orientation and informed consent, 51 volunteers were randomly assigned in a 2:1 ratio to a 6-month program of probation plus naltrexone and brief drug counseling, or probation plus counseling alone. Naltrexone subjects received medication and counseling twice a week; controls received counseling at similar intervals. All therapy and medication were administered in an office located adjacent to the federal probation department. Fifty-two percent of subjects in the naltrexone group continued for 6 months and 33% remained in the control group. Opioid use was significantly lower in the naltrexone group. The overall mean percent of opioid positive urine tests among the naltrexone subjects was 8%, versus 30% for control subjects (p < .05). Fifty-six percent of the controls and 26% of the naltrexone group (p < .05) had their probation status revoked within the 6-month study period and returned to prison. Treatment with naltrexone and brief drug counseling can be integrated into the Federal Probation/Parole system with favorable results on both opioid use and re-arrest rates.

This study compared the treatment response of four groups of psychiatrically diverse opiate-dependent, methadone maintenance patients receiving drug counseling. The four groups were patients with no other nonsubstance abuse axis I psychiatric diagnoses (OP only; N = 65), patients with lifetime major depression (DEP; N = 60), patients with both antisocial personality disorder and lifetime major depression (APD + DEP; N = 35), and patients with only APD (APD only; N = 24). Patients were assessed at intake, during treatment, and 7 months after treatment admission. No statistically significant differences were found among the groups in treatment retention/attendance. Few significant group differences were revealed during-treatment urine screens, except that barbiturate use was more common for the APD only group. The APD only group also had significantly more positive urine screens for benzodiazepines than the other three groups at 7-month follow-up. All groups reported considerable improvement in problem level at 7 months compared with admission status. The APD only group reported fewer gains in legal and employment problems than the other groups but reported greater improvement in the drug area. Thus, there was some limited support for a prior finding, based on individual psychotherapy, that the treatment response of APD only patients was inferior to that of APD + DEP patients or non-APD patients.

Problems of alcohol and drug dependence are costly to society in terms of lost productivity, social disorder, and avoidable health care utilization. The dollar costs of alcohol and drug use run into billions of dollars, and from one-eighth to one-sixth of all deaths can be traced to this source. However, the efficacy of treatment for addiction is often questioned. A rationale for reasonable expectations of addiction treatments is offered, from which are derived three outcome criteria for judging the effectiveness of treatments: reduction in substance use; improvement in personal health and social function; and reduction in public health and safety risks. Based on these criteria, treatment was shown to be effective, especially when compared with alternatives like no treatment or incarceration. These evaluations, which were conducted in a scientific manner, support the continued value of public spending for carefully monitored treatment of addiction.
