We investigated the characteristics of human immunodeficiency virus (HIV)-positive injection drug-using women who reported unprotected vaginal and/or anal sex with HIV-negative or unknown serostatus (serodiscordant) male partners. Of 426 female study participants, 370 were sexually active. Of these women, 39% (144/370) and 40% (148/370) reported vaginal and/or anal sex with serodiscordant main and casual partners, respectively. Sixty percent of women inconsistently used condoms with their serodiscordant main partners, whereas 53% did so with casual partners. In multivariate analysis, during sex with main partners, inconsistent condom users were less likely to feel confident about achieving safe sex (self-efficacy), personal responsibility for limiting HIV transmission, and that their partner supported safe sex. Inconsistent condom use was also more likely among women who held negative beliefs about condoms and in couplings without mutual disclosure of HIV status. Regarding sex with casual partners, inconsistent condom users were more likely to experience psychologic distress, engage in sex trading, but they were less likely to feel confident about achieving safe sex. These findings suggest that there are widespread opportunities for the sexual transmission of HIV from drug-using women to HIV-uninfected men, and that reasons vary by type of partnership. Multifaceted interventions that address personal, dyadic, and addiction problems are needed for HIV-positive injection drug-using women.

We explore the links between substance use, misuse, addiction, and dependency1 and sexuality, sexually transmitted diseases (STD), human immunodeficiency virus (HIV), and acquired immune deficiency syndrome (AIDS) to increase our awareness of their interdependence and to identify new ways to perceive, judge, and intervene (or not to) with associated problems. We consider the sociocultural and economic context in which these behaviors occur; the impact these behaviors have on one another; the personal opinions and attitudes; the religious, moral, or political beliefs and agendas; the physiological and fiscal constraints; and theories of rational decision-making and psychological motivation that act to increase or reduce the incidence of these behaviors and their sequellae, while hindering or facilitating prevention, harm reduction, and treatment interventions. Mechanisms of epidemic spread of STDS/HIV/AIDS are presented in the Appendix. Each of these terms are loaded "container concepts" that are culture-bound and stakeholder-driven and whose dimensions are less than consensus-based. They represent a range of meanings, uses, and misuses in an ongoing politicalized area of human and systemic functioning and adaptations.

Drug abuse and infection with human immunodeficiency virus (HIV) are associated with high rates of morbidity and mortality, but, because of medical, social, and legal factors, opiate addiction/dependence is a major obstacle to successful treatment of disease--for example, treatment of acquired immunodeficiency syndrome (AIDS) with highly active antiretroviral therapy. In an effort to improve the opportunity for treatment of drug abuse and HIV infection, the Forum for Collaborative HIV Research, in collaboration with the Substance Abuse and Mental Health Services Administration, the National Institute on Drug Abuse, the Centers for Disease Control and Prevention, and other agencies, presented a workshop entitled "Buprenorphine in the Primary HIV Care Setting." Participants reviewed and discussed current issues, such as the introduction of and sources for the provision of buprenorphine in HIV primary care settings and strategies for integrating treatment of HIV-infected drug abusers, all of which are covered in this supplement.

The Centers for Disease Control and Prevention's HIV Prevention Strategic Plan Through 2005 advocated for increasing the proportion of persons with human immunodeficiency virus (HIV) infection and in need of substance abuse treatment who are successfully linked to services for these 2 conditions. There is evidence that integrating care for HIV infection and substance abuse optimizes outcomes for patients with both disorders. Buprenorphine, a recently approved medication for the treatment of opioid dependence in physicians' offices, provides the opportunity to integrate the treatment of HIV infection and substance abuse in one clinical setting, yet little information exists on the models of care that will most successfully facilitate this integration. To promote the uptake of this type of integrated care, the current review provides a description of 4 recently implemented models for combining buprenorphine treatment with HIV primary care: (1) an on-site addiction/HIV specialist treatment model; (2) a HIV primary care physician model; (3) a nonphysician health professional model; and (4) a community outreach model.

Peripheral neuropathy (PN), associated with diabetes, neurotoxic chemotherapy, human immunodeficiency virus (HIV)/antiretroviral drugs, alcoholism, nutrient deficiencies, heavy metal toxicity, and other etiologies, results in significant morbidity. Conventional pain medications primarily mask symptoms and have significant side effects and addiction profiles. However, a widening body of research indicates alternative medicine may offer significant benefit to this patient population. Alpha-lipoic acid, acetyl-L-carnitine, benfotiamine, methylcobalamin, and topical capsaicin are among the most well-researched alternative options for the treatment of PN. Other potential nutrient or botanical therapies include vitamin E, glutathione, folate, pyridoxine, biotin, myo-inositol, omega-3 and -6 fatty acids, L-arginine, L-glutamine, taurine, N-acetylcysteine, zinc, magnesium, chromium, and St. John's wort. In the realm of physical medicine, acupuncture, magnetic therapy, and yoga have been found to provide benefit. New cutting-edge conventional therapies, including dual-action peptides, may also hold promise.

In Ethiopia human immunodeficiency virus (HIV) infection is a major health and socioeconomic problem. Sex workers, youth, and mobile populations all show increasing prevalence of HIV. However, there is currently no information about the seroprevalence of HIV and the knowledge of HIV among street dwellers in the country. To fill this gap, 404 street dwellers residing in Gondar, northwest Ethiopia, were included in this cross-sectional study. Socio-demographic data, factors that prompted the subjects to become street dwellers, and their knowledge about HIV were all assessed using a structured questionnaire. Stool samples for diagnosis of intestinal parasites and venous blood for HIV antibody testing were collected and processed following standard procedures. Poverty-associated movement to urban areas in search of work was reported as a major factor that forced them to live in the streets, followed by divorce, family death, and addiction and peer pressure. One or more intestinal parasites were found in 67.6% of the street dwellers. Multiple parasitic infections were detected in 27.7%. The prevalence of HIV in the street dwellers was 6.9%. Fifty-nine (16.6%) participants responded that HIV can be transmitted by eating food together. Seventy-three (18%) believed an infected needle cannot transmit HIV, while 51 (12.6%) said HIV can be transmitted by hand shaking. One hundred ninety-two (47.5%) responded that antiretroviral therapy will not prolong the life of HIV-infected individuals. In summary, the prevalence of HIV and intestinal parasitic infection was quite high among street dwellers in Gondar. Therefore, strategies to control HIV and other infectious diseases should include this group, and regular mass deworming may help to reduce the burden of infection.

Approximately 7 million people in the United States are in jail, in prison, or on probation or parole, many as a result of drug-related offenses. Individuals who use opiates account for a significant minority of this population. Methadone maintenance treatment (MMT) of opiate addiction is highly effective in reducing drug use, drug-related criminal activity, and risk of human immunodeficiency virus transmission. Recently released inmates are at particularly high risk for overdose and disease transmission. Project MOD (Managing Opioid Dependency) provides services to eliminate logistical and financial barriers to MMT entry immediately on release from incarceration. Such programs provide a promising opportunity to facilitate reentry into the community, combat disease transmission, and reduce recidivism.

Methadone maintenance therapy (MMT) has been increasingly implemented as the treatment of choice for opiate-addicted individuals and has been associated with reduced harm related to opiate addiction. Barriers to MMT uptake still exist, however, and many opiate-addicted individuals do not access this form of treatment. We examined barriers to and facilitators of MMT access among opiate users enrolled in a prospective cohort study of injection drug users (IDUs). We identified individuals who had initiated MMT during follow-up interviews and used generalized estimating equations to identify sociodemographic and drug-related variables associated with MMT access. Of the 1,587 participants recruited into the Vancouver Injection Drug User Study, 1,463 individuals were eligible for the present analysis. Factors negatively associated with MMT use included male gender (odds ratio [OR] = 0.41; 95 percent confidence interval [CI], 0.32 to 0.52), Aboriginal ethnicity (OR = 0.37; 95 percent CI, 0.29 to 0.48), recent incarceration (OR = 0.82; 95 percent CI, 0.72 to 0.93), Downtown Eastside residence (OR = 0.86; 95 percent CI, 0.75 to 0.97), sex-trade involvement (OR = 0.80; 95 percent CI, 0.67 to 0.95), syringe lending (OR = 0.76; 95 percent CI, 0.66 to 0.89), denied addiction treatment (OR = 0.81; 95 percent CI, 0.68 to 0.96), heroin injection (OR = 0.51; 95 percent CI, 0.44 to 0.59), nonfatal overdose (OR = 0.59; 95 percent CI, 0.51 to 0.68), and infecting in public (OR = 0.75; 95 percent CI, 0.63 to 0.89). Older age (OR = 1.03; 95 percent CI, 1.01 to 1.04), human immunodeficiency virus (HJV) positivity (OR = 1.89; 95 percent CI, 1.52 to 2.2.3), and crack cocaine smoking (OR = 1.41; 95 percent CI, 1.22 to 1.62) were positively associated with MMT use. Our study identified a large number of barriers to and facilitators of MMT use among IDUs. While some populations such as HIV-positive individuals are frequently accessing MMT, identified barriers among men and Aboriginal lDUs are of great concern. These findings indicate the need for additional interventions aimed at maximizing coverage of MMT and other treatments for opiate-addicted individuals.

The National Drug Abuse Treatment Clinical Trials Network conducted this study to determine the availability of and factors associated with infection-related health services in substance abuse treatment settings. In a cross-sectional descriptive design, state policies, reimbursement for providers, state level of priority, and treatment program characteristics were studied via written surveys of administrators of substance abuse treatment programs and of state health and substance abuse departments. Data from health departments and substance abuse agencies of 48 states and from 269 substance abuse treatment programs revealed that human immunodeficiency virus/acquired immunodeficiency syndrome-related services are more frequent than hepatitis C virus or sexually transmitted infection-related services, and that nonmedical services are more frequent than medical services. While the availability of infection-related health services is associated with medical staffing patterns, addiction pharmacotherapy services, and state priorities, reimbursement was the most significant determining factor. These findings suggest that greater funding of these health services in substance abuse treatment settings, facilitated by supportive state policies, represents an effective response to the excess morbidity and mortality of these substance use-related infections.

Substance abuse still remains one of the major problems in the world today, with millions of people abusing legal and illegal drugs. In addition, a billion people may also be infected with one or more infections. Both drugs of abuse and infections are associated with enormous burden of social, economic, and health consequences. This article briefly discusses a few medical consequences of drugs of abuse and infections such as human immunodeficiency virus, hepatitis C virus, psychiatric complications in hepatitis C infection, pharmacokinetic drug-drug interactions among medications used in the treatment of addiction and infections, and new drugs in development for the treatment of infections. Research is encouraged to study interactions between infections, drugs of abuse, and underlying pathophysiologic and molecular/genetic mechanisms of these interactions.
