A comprehensive study of an urban methadone clinic with supervised urine analyses for illicit drugs was conducted over an 18 month period for a 133 patient cohort as they entered or remained in methadone maintenance for narcotic addiction. Overall retention during the study was 85%, with significantly (p < .05) higher daily methadone doses (mean 67.1 mg +/- 2.1) in those patients still in treatment at the end of the study. Predictably, illicit opioid use was dramatically reduced, to 10% as measured by urine toxicology in the last month of treatment. Moreover, significantly more patients stopped regular cocaine abuse (69%) than started using cocaine (10%, Fisher's exact test, p = .02). Thus, with effective methadone maintenance using adequate dosages, the majority of patients remain in treatment and reduce cocaine abuse as well as illicit opioid use, with implications for public health by reducing the spread of infectious diseases including hepatitis B, C, D and human immunodeficiency virus (HIV-1).

In an effort to understand issues affecting prenatal care access and utilization from the perspectives of human immunodeficiency virus (HIV)-infected women who receive inadequate prenatal care, we conducted three in-depth qualitative and quantitative interviews. From a thematic analysis of the narrative interviews, four broad areas emerged as pertinent to these women's prenatal care experiences. These were issues related to pregnancy, HIV, psychosocial conditions, and the health care system. For these women, the barriers to prenatal care utilization included the unexpected and unplanned nature of the pregnancy and mental health issues related to HIV infection. Poverty, periodic homelessness, addiction to illicit substances, and lack of social support were also important barriers. Furthermore, perceptions of the health care system as threatening, including fears related to consequences of disclosing illicit activities, discrimination, and breach of confidentiality emerged as salient barriers. Facilitating factors included the pregnancy being experienced as a life-transforming event, concern for their children, especially preventing HIV-1 vertical transmission, availability of treatment, and support from health care professionals. Prominent throughout the interviews were the women's mental health concerns and need for professional support.

The characteristics of cell-mediated and humoral immunity were studied in 611 patients with different etiological forms of acute virus hepatitides (HB, HC, HB + C, HC + HBsAg). As the result of the systematic abuse of psychoactive preparations, introduced by intravenous injection, in 166 patients (27.2%) drug addiction developed, ehile 445 (72.8%) patients had no addiction. The study revealed that in drug users with HB the secondary T-cell immunodeficiency of the hyposuppressor type in combination with depression in B-cell-mediated immunity (a decrease in the absolute number of B lymphocytes) could be registered, and in patients having no drug addiction the secondary T-cell immunodeficiency characterized by a decrease in the content of T helpers simultaneously with the increased content of T suppressors and B lymphocytes.

This cross-sectional study investigated the prevalence and risk factors of hepatitis B virus (HBV), hepatitis C virus (HCV), and human immunodeficiency virus (HIV) infections among 266 drug users attending a drug-addiction treatment centre in Dhaka, Bangladesh, from November 1996 to April 1997. Of the 266 addicts, 129 were injectable drug users (IDUs), and 137 were non-injectable drug users (non-IDUs). The seroprevalences of hepatitis B virus surface antigen (HBsAg), anti-HBc, anti-HBs, and anti-HCV antibodies among the IDUs were 8 (6.2%), 41 (31.8%), 15 (11.6%), and 32 (24.8%), and among the non-IDUs were 6 (4.4%), 33 (24.1%), 9 (6.6%), and 8 (5.8%) respectively. None of the drug users were positive for anti-HIV antibody. Although the prevalence of HBV infection did not significantly differ between the IDUs and the non-IDUs, the prevalence of HCV infection was significantly higher among the IDUs. Among the IDUs, the prevalence of both HBV and HCV infections was associated with sharing of needles and longer duration of injectable drugs used. The seroprevalence of HBV infection in both IDUs and non-IDUs was significantly higher among those who had a history of extramarital and premarital sex. The prevalence of HCV infection was not associated with sexual promiscuity. There was no association between the seroprevalence of HBV and HCV infections and age. Active preventive programmes focusing on educational campaigns among the youths against substance abuse should be undertaken.

Injection drug use is associated with high risk for transmission of bloodborne infections, including human immunodeficiency virus (HIV) and hepatitis B and C. Since 1993, the proportion of persons admitted to New Jersey addiction treatment centers for illicit drug use who reported injecting drugs has increased, reversing a decline that began in approximately 1980 (1; Community EpidemiologyWork Group, unpublished data, 2000). This report summarizes an analysis of trends in injection drug use among persons admitted to New Jersey addiction treatment programs during 1992-1999; the findings suggest substantial increases in injection use among young adult heroin users throughout the state and an increase in heroin use among young adults who reside in suburban and rural New Jersey.

Injection drug users represent a major vector of human immunodeficiency virus (HIV) infection in the nation's inner cities, and are an important population for harm reduction treatment interventions to target. However, there has been relatively little research examining the specific contribution of the multiple factors contributing to cognitive functioning among injection drug users that may affect engagement in, and response to, addiction and HIV-related interventions. The current study examined the independent contributions to neuropsychological (NP) test performance of premorbid educational attainment, medical and psychiatric history, long- and short-term drug use, assessed by laboratory, observation, and self-report measures, and HIV disease, assessed by plasma HIV-1 RNA viral load and CD4+ count, in a sample of 90 HIV-positive injection drug users dually addicted to heroin and cocaine. Fully 88% of the sample showed evidence of impairment (>1 standard deviation below the population mean) on an NP test battery selected to assess processes associated with successful engagement in the treatment of substance abuse and HIV, such as learning and memory of verbal information, capacity to solve new problems and deal with more than one stimulus at a time, visual-motor coordination, and visual tracking and cognitive flexibility. In addition to drug use, independent predictors of NP test performance were HIV viral load, educational attainment, and premorbid medical and psychiatric problems. Findings underscore the multiplicity of factors that contribute to cognitive impairment in HIV-positive drug-abusing individuals in addition to drug use. Clinical implications are discussed.

Prison populations throughout the Unites States are growing; the 1990s saw an average 6.5% per year increase. Average inmate age is increasing, as are both the number and rate of inmate deaths. Aging inmates experience health concerns typical of the general, free, aging population. Inmates have higher incidence of health complications associated with various circumstances, risk behaviors, and associated medical conditions. These circumstances include prison violence, incarceration-related constraints on exercise, and diet. Inmates are more likely to have a history of alcohol abuse, substance abuse or addiction and sex industry work. Risk-behavior conditions include human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS), hepatitis B and C, liver disease, tuberculosis, endocarditis, and cardiomyopathy. Hospice is increasingly the preferred response to the health and care needs of terminally ill inmates. Implementing hospice behind bars has some unique challenges in addition to those inherent in hospice work. This series will provide an in-depth look at four hospice programs for inmates in the United States.

Infection with the human immunodeficiency virus (HIV) is spreading rapidly among injection drug users (IDUs), particularly in countries of the Golden Triangle where Myanmar (Burma), Thailand, and Laos converge and the pure heroin China White is refined. Thailand, Myanmar, Hong Kong, Malaysia, Singapore, the southern provinces of China, and the northeastern states of Mizoram, Manipur and Nagaland in India are affected. Infection has reached 50% and more in some groups of IDUs in these countries. In Thailand, 63% of the 23,845 known cases of HIV infection are among an estimated 400,000 IDUs. It is estimated that Myanmar has 160,000 IDUs, of whom half are infected with HIV, and among 85,000 IDUs tested, 85% were infected. The Myanmar sector of the Golden Triangle produces double the amount of the mid-1980s, more than 2000 tons of raw opium a year impaction northeastern India and China's southwest Yunnan province. The HIV infection rate among IDUs tested in Manipur was 50% in 1991, and 40% of an estimated 10,000 IDUs in neighboring Nagaland carry the virus. In China 398 of the 493 registered HIV cases are among IDUs in Yunnan. In Malaysia, there are nearly 4000 cases of HIV infection, approximately 80% of which are IDUs. The epidemic of heroin injection swept over Asia in the last decade, since Afghanistan, Pakistan, and Iran were major heroin producers. An estimated is 10 of Karachi's 8 million population uses drugs. Criminal syndicates in Pakistan, Afghanistan, and India control production, manufacture and wholesale distribution of heroin using sophisticated systems. Addiction is punishable in only a few countries, as most countries distinguish between the selling of drugs and consumption. WHO placed the interdiction of IDUs and HIV in Asia on its agenda at a meeting in Thailand, in October 1991, to prevent a shift toward drug injecting in countries where drugs are still largely inhaled.

A sample of 193 southern Brazilian inner-city cocaine abusers was studied to assess the prevalence of human immunodeficiency virus (HIV) infection. Following the exclusion of those who were seropositive from the intake sample, a cohort of 138 HIV-negative cocaine abusers was followed for 18 months to assess seroincidence rates and the associated characteristics. HIV status, drug use, sexual risk behaviors, and presence and severity of medical and psychiatric symptoms were collected at intake using a Brazilian version of the Risk Assessment Battery, the Addiction Severity Index (ASI), Symptom Check List-90 (SCL-90), and Beck Depression Inventory (BDI); this was repeated at 6-, 12-, and 18-month intervals. The overall seroprevalence was 28.5%, and the variables associated with HIV seropositivity were age older than 25 years, being single, having less than 8 years of education, and having injected cocaine at least once. Although follow-up procedures were difficult to implement due to sample characteristics, we obtained data from 82.6% of the participants for at least one follow-up and for 57% at all follow-up windows. Most participants showed high scores on the Beck Depression Inventory (mean of 20.6 +/- 13.9) and Symptom Check List-90 (mean of 106.4 +/- 91.9). There were 8 seroconversions in the 18-month period, yielding an incidence rate of 5.03/100 (confidence interval [CI] 2.2-9.7) person-years at risk. None of the seroconverters reported recent cocaine injection, and only 14.5% of the overall sample reported ever injecting cocaine, which suggests that another significant mode of transmission via sexual behavior should be considered as well. Each of these findings has important implications for the design of preventive interventions.

Opiate addiction has been reported to contribute to the progression of renal injury. In addition, opiate addiction is a major risk factor for the development of human immunodeficiency virus-associated nephropathy. In the present study, we evaluated the effects of morphine, an active metabolite of heroin, on glomerular epithelial cell (GEC) growth and the involved molecular mechanism. At lower concentrations, morphine promoted GEC proliferation; however, at higher concentrations, morphine triggered apoptosis. Antioxidants inhibited morphine-induced proliferation as well as apoptosis. Similarly, free radical scavengers prevented morphine-induced GEC proliferation and apoptosis. Because proliferative and proapoptotic effects of morphine were inhibited by free radical scavengers as well as antioxidants, it appears that these effects of morphine are mediated through oxidative stress. Hemin, an inducer of heme oxygenase (HO) activity, inhibited GEC proliferation and promoted GEC apoptosis under basal and morphine-stimulated conditions. On the other hand, zinc protoporphyrin, an inhibitor of HO activity, promoted GEC proliferation and inhibited GEC apoptosis under basal as well as morphine-stimulated conditions. These findings suggest that HO activity is directly related to GEC apoptosis and inversely related to GEC proliferation. Morphine, de novo, had bimodal effects on HO activity: lower concentrations increased and higher concentrations decreased HO activity. It appears that HO activity may be modifying morphine-induced GEC growth.
