Prevention of HIV transmission.

With screening of the blood supply and effective heat and chemical treatment of blood product derivatives, the overwhelming majority of newly acquired adult HIV infections will result from consensual acts, through the exchange of blood or sexual secretions. Societal relaxation about discussion of sex, death, homosexuality, drugs, and abortion is essential to prevent further deaths. Careful partner selection, use of condoms in conjunction with nonoxynol-9 (a viricidal spermicide), and selected confidential HIV antibody testing could help decrease the number of infected persons. Efforts directed toward IV drug users to decrease initiation of drugs, make drug treatment more accessible, provide simple techniques for cleaning needles such as a quick rinsing with bleach and water, and emphasizing the risks of sharing needles could decrease the exponential rise of HIV infection in IV drug users. A substantial percentage of women infected with both HIV and hepatitis B are unaware of their infection. Information, counseling, and antibody testing of men and women prenatally with informed options could reduce infection in children. Health care providers must work through their own valid issues of fear and possible discomfort with various lifestyles to function effectively in the health professions.

[Infection and disease caused by the human T cell lymphotropic viruses type I and II in Brazil].

HTLV-I/II infection is present in all regions of Brazil, but its prevalence varies according to the geographical area, being higher in Bahia, Pernambuco and Pará. It has been estimated that Brazil has the highest absolute number of infected individuals in the world. Blood donors screening and research conducted with special groups (indigenous population of Brazil, IV drug users and pregnant women) are the major sources of information about these viruses in our Country. HTLV-I causes adult T cell leukemia/lymphoma (ATLL), HTLV associated myelopathy/tropical spastic paraparesis (HAM/TSP), HTLV associated uveitis (HAU), dermatological and immunological abnormalities. HTLV-II is not consistently associated with any disease. Diagnosis is established using screening (enzymatic assays, agglutination) and confirmatory (Western blot, PCR) tests. The viruses are transmitted by blood and contaminated needles, by sexual relations and from mother to child, especially by breast feeding. Prevention efforts should focus on education of positive blood donors, infected mothers and IV drug users.

Anticardiolipin antibodies and pregnancy outcome in women with human immunodeficiency virus infection.

Abnormal anticardiolipin antibodies are associated with adverse pregnancy outcome in the general obstetric population. We studied 55 pregnancies in women infected with human immunodeficiency virus type 1 (HIV-1) to examine two hypotheses: that a substantial proportion of these women would have raised anticardiolipin antibodies, and that the affected pregnancies would be more likely to be complicated by preterm delivery and intrauterine growth retardation. Blood was taken at the initial antenatal visit, and was also taken from 15 HIV-seronegative intravenous (IV) drug users and 20 controls with no drug history. The reference for immunoglobulin G class antibodies to cardiolipin was calculated from 50 healthy young adults, and the upper limit of normal was defined as 4 standard deviations above the mean for this reference series. Twenty-four percent of the infected women, but none of the HIV-seronegative IV drug users and none of the control group, had raised anticardiolipin antibodies. There was no statistically significant relationship with birth weight, standardized birth weight, length, gestation, occipitofrontal circumference, or adverse pregnancy outcome. No women gave a history of thromboembolism or recurrent abortion, and in no pregnancy was there clinically apparent thromboembolism. We conclude that abnormal anticardiolipin antibodies provoked by HIV infection are common, but probably have a narrow specificity for cardiolipin, are unrelated to phospholipid antibody syndrome, and cannot explain adverse pregnancy outcome in HIV-infected women.

Decline in intravenous drug use among treatment-seeking opiate users.

Opiate users seeking treatment during similar time periods in 1986 (n = 60) and 1988 (n = 82) did not differ significantly with regard to demographic factors, length of addiction, use of cocaine, history of alcohol problems, or indices of depression. In 1988, however, users reported significantly lower rates of current intravenous drug use than was reported in 1986: 39% in 1988, compared to 14% in 1986, reported not currently using IV (chi 2(1, N = 142) = 11.302, p < .001). For the combined periods, current IV users (n = 102) did not differ significantly from those who were not currently using IV (n = 40) with regard to demographic factors, size of habit, history of alcohol problems, or indices of depression. Current IV users had used opiates longer (mean 11.3 years versus 8.4 years; t(1, 65) = 2.20, p < .03), and there was a trend for cocaine use to be associated with current IV administration. For the smaller subset of those who survived waiting lists of between 1 to 4 months from the time of intake to program admission and physical examination (n = 81), 35% (6/17) of those who were not IV drug users at the time of clinic intake reported resuming or initiating IV drug use by the time of program admission. The validity of self-reports of not using IV at the time of program admission was assessed by comparison of self-report with findings of track marks on physical examination: inconsistencies were detected in 11% (1/9) of those whose self-reports indicated no current IV use.

Willingness of high school students to perform cardiopulmonary resuscitation and automated external defibrillation.

OBJECTIVE: To evaluate the willingness of high school students to perform cardiopulmonary resuscitation (CPR) and automated external defibrillation (AED). METHODS: A convenience sample of high school students was surveyed regarding how they would respond if they witnessed a cardiac arrest. Participants were first shown a video segment on the operation of an automated external defibrillator. They were then shown a series of video clips depicting six different cardiac arrest scenarios: motor vehicle collision (MVC) with facial bleeding, pediatric drowning, intravenous (IV) drug user, choking family member, victim of differing race, and victim with facial vomitus. Following each video, the subjects were asked how they would respond had they actually witnessed a similar event. RESULTS: With parental permission and institutional review board approval, 683 students participated, representing 6.8% of the total student body. Of these, 585 (86%) were trained in CPR and 142 (21%) in AED. One hundred six participants (16%) had witnessed a cardiac arrest prior to the survey. Of these, 24 (23%) had intervened in some way. Twenty (19%) had performed mouth-to-mouth resuscitation (MMR), 15 (14%) had performed chest compressions (CC), and one (0.9%) had performed AED. Across all six mock scenarios and all 683 respondents collectively (4,098 simulated cardiac arrest events), the respondents indicated they would be willing to perform AED 1,308 times (32%). In comparison, the respondents indicated they would be willing to perform MMR 1,768 times (43%) and CC 2,249 times (55%). More respondents were willing to intervene on behalf of a child or family member, while fewer were willing to act in the setting of blood, vomitus, or an IV drug user (p < 0.05). There was no association between willingness to intervene and prior experience with any of the interventions. Fear of infection, legal consequences, and fear of harming the patient were the most frequently cited reasons for not intervening. CONCLUSIONS: Among high school students, few are willing to perform automated external defibrillation. Willingness to perform MMR and CC appears to depend on the circumstances.

HIV, heroin and heterosexual relations.

This ethnographic study describes part of the social context in which heterosexual transmission of the human immunodeficiency virus (HIV) may be taking place. Based on interviews with sex partners of intravenous (IV) drug users in an urban, African American community of the United States, the study documents the personal experience of 35 men and women to show how living with one's own and/or one's partner's heroin habit may structure one's response to public health information and one's possibility of becoming infected with HIV. As described by sex partners of intravenous drug users, people who use heroin habitually are drawn into social networks that are loosely organized according to their preferred route of drug administration, i.e. 'shooters' (intravenous) and 'tooters' (intranasal), both of which tend to exclude 'squares' (non-use). Social divisions such as these may slow rates of HIV transmission to those outside the drug life. But nevertheless, as sex partners explain, there are many types of social and sexual exchanges taking place among shooters, tooters and squares, including but not limited to the exchange of bodily fluids. Ethnography analyzes discursive representations of such exchanges, filling in and questioning the empty categories of epidemiological prediction. How does risky behavior actually figure in the lives of individuals who happen to fall in the category of 'sex partner'? How is sexual behavior shaped by drug use behavior? Being sexually involved with an IV drug user for some years alters a person's relative position betwixt and between the drug subculture, on the one hand, and mainstream pursuits of family, work and church, on the other. Differences in personal need and group identity create conflicts. Couples in long-term relationships develop rules to manage these. But in which terms will they interpret and negotiate the new threat of AIDS? If the strategic aspect of discursive representations of experience is taken into account, and if discursive representations are interpreted within appropriate social and historical contexts, they can provide a rich source of material for understanding the social impact of the AIDS epidemic. Without this discursive dimension, analytic power to interpret seroprevalence data cross-culturally would be lacking. In addition, and independently of the problem of interpreting seroprevalence data, ethnographic analysis links local, culturally-specific meanings through which AIDS is interpreted to our understanding of AIDS as a global phenomena.

Practices reported by incarcerated drug abusers to reduce risk of AIDS.

The nation's response to AIDS has failed to effectively curb the spread of AIDS among intravenous (IV) drug users, who are primarily responsible for transmitting the disease to heterosexuals and children. A study assessing awareness of AIDS among 58 county jail inmates--27 IV drug abusers and 31 nonintravenous drug abusers--found that a minority had received formal AIDS education. All of the subjects claimed to be taking some precautions against AIDS, but IV drug abusers were significantly more fearful about contracting AIDS than were nonintravenous users. Less than half of either group knew that asymptomatic carriers of the AIDS virus were infectious. IV drug users who reported no longer sharing needles (56 percent) or no longer shooting drugs (22 percent) were more likely than those who took less effective precautions to believe that individuals had control over events. County jails and other correctional institutions are urged to educate inmates about AIDS prevention.

Building skills of recovering women drug users to reduce heterosexual AIDS transmission.

Although most women infected with HIV are intravenous drug users, some contact the virus through sexual contact with IV drug users. To reach at-risk women, public health officials must develop a range of prevention strategies. One approach, skills training, holds promise as a means of altering risk-related sexual behavior. In this study, 91 women methadone patients were pretested and randomly assigned to an information-only control control group or a skills-building intervention group. Skills-building intervention consisted of five sessions of small groups in which participants identified their own high risk sexual behaviors, discussed their negative associations with condoms, and practiced skills which involved asking partners to use condoms. Compared with members of the control group, respondents in the intervention group reported that they initiated discussion of sexual issues with their partners more frequently, felt more comfortable talking with them about safer sex, and reported using and carrying condoms more frequently. The high rates of attendance and program retention by skills-building participants suggest that such groups may be supportive and useful in the design of risk reduction and drug abuse treatment programs. The modest outcomes of this study underscore the difficulty of altering risk behavior but also serve as a basis for future AIDS prevention studies.

Diagnosis and management of acquired immune deficiency syndrome in intravenous drug users.

Acquired Immune Deficiency Syndrome (AIDS) is a clinical entity that is part of a spectrum of immune dysfunction found in specific high risk groups, among them intravenous drug users. In drug users AIDS almost always presents as an opportunistic infection, usually Pneumocystis carinii. The leading etiologic hypothesis is of a viral agent acting, it is possible, on a previously immunocompromised host. Recent research at hospitals affiliated with The Albert Einstein College of Medicine, where an unusually large proportion of AIDS patients are drug users, is described. Suggestions are advanced for the management of IV drug users with immune dysfunction.

Human T cell leukemia virus (HTLV-I/II) serodiagnostic testing: disparate results among a cohort of intravenous drug users.

Three hundred and forty-six sera collected over a 2-year period from 154 San Francisco IV drug users were subjected to HTLV-I/II RIPA, Western blot (WB), Du Pont ELISA, and p24 radioimmunoassay (RIA). Tests were performed at separate sites and code not broken until study end. RIPA-positive and -negative controls consisted of Japanese adult T cell leukemia patients, healthy blood donors, and non-IV drug-using HIV-positive men. RIPA identified HTLV-I/II-positive sera not identified by the other tests. Positive RIPAs were noted in 43% of negative ELISAs (n = 279), 34% of negative WBs (n = 243), and 40% of negative RIAs (n = 270). Seventy-two sera were negative by all 3 assays, but were RIPA positive. All sera positive by RIA (n = 76) and WB (n = 67), and 66 of 67 by ELISA, were positive by RIPA. Thirty-five of 36 indeterminate WBs were RIPA positive. Seven samples indeterminate by RIPA were negative by WB and RIA; one of seven was positive by ELISA. In all instances, samples negative by RIPA (n = 154) were ELISA, p24 RIA, and WB negative or indeterminate. We conclude that when studying HTLV-I/II-endemic cohorts, screening ELISA or RIA followed by confirmatory WB or RIPA only of seropositive samples may result in a substantial number of undetected cases. Additional studies focusing on performance characteristics of serodiagnostic tests are needed to ensure accurate inferences are made in assessing HTLV-I/II prevalence rates among high-risk groups. The RIPA may be a uniquely sensitive assay to detect HTLV-I/II gene-encoded products.

Illicit use of methadone among i.v. drug users in Montreal.

Few studies have been done on the prevalence of illicit methadone use. Five hundred fifty-nine IV drug users recruited in various ways in Montreal were interviewed concerning their drug use as part of a longitudinal study on HIV infection. Of this number, 133 had heroin as their drug of preference and 426 cocaine. Among the cocaine group, 202 also used heroin. The lifetime prevalence of any illicit methadone use was 59.4% in the heroin group, 26.7% in the cocaine/heroin group, and 3.6% in the cocaine-only group. The 6-month (preceding the interview) prevalence of any illicit use was 42.1%, 6.9%, and 1.3%, respectively, and the prevalence of at least weekly illicit use during that period was 6.3%, 2.0%, and 0%, respectively. The prevalence of illicit methadone use is significant in the population studied. Whether this level of use will be affected by more stringent control on methadone prescription and dispensation remains to be demonstrated.

Comparison of HIV antibody profiles in intravenous drug users and individuals infected by the sexual route.

HIV-1 antibody patterns in two groups, those infected by the intravenous route (IV drug users) and those infected by the sexual route (prostitutes, male homosexuals and sexually transmitted disease patients) were compared using the Western blot technique. A total of 160 cases were studied. The intravenous drug user (IVDU) group appeared to respond to fewer antibody markers than the sexually infected group, the difference being significant for markers p31, p51, p55, p66, gp41 and gp120. Furthermore, a higher proportion (63%) of the sexually infected group carried antibodies to all Western blot markers as compared to the IVDU group (49%).

The why, when and whether of condom use among female and male drug users.

Eight focus groups consisting of all male, all female and mixed male and female drug users were conducted to gain an in-depth understanding of beliefs and behavior regarding the use of family planning services and contraceptives, particularly condom use in an effort to reduce the perinatal transmission of HIV. While participants often supported the use of condoms because of STDs and AIDS, their unplanned pregnancies and STD histories indicated in-consistent use, depending on the partner and the circumstances. The vast majority of both men and women did not like to use condoms because it interfered with the spontaneity and pleasure of sexual relations, though women seemed more willing to use condoms than their partners. Participants varied in their knowledge about the benefits of using a condom, in how and when to put it on, in the associations they made between condom use and trust and commitment, in the type of partner and conditions under which they would use condoms and in their willingness to consider condom use as an integral part of their lives. Issues of trust, commitment and condom use did not seem to have been resolved in the drug using community, particularly among younger people who appeared to have more difficulty in negotiating condom use. Promoting the use of condoms needs to be considered as part of a larger, multifaceted behavior change effort.

Confronting the AIDS epidemic among i.v. drug users: does ethnic culture matter?

The AIDS education and prevention literature contains numerous calls for the development of culturally relevant efforts to reach members of ethnic minority populations. In the AIDS literature on IV drug users (IVDUs), however, this issue finds less emphasis despite the disproportionate rate of human immunodeficiency virus (HIV) infection in minority IVDUs. The reason appears to be the sense in the drug field that the primary culture of the IVDU is drug culture rather than ethnic culture. This paper explores this issue in light of a review of recent research on IVDUs, ethnicity, and AIDS risk behavior. Specifically, this review covers literature on 6 topics in light of ethnic differences: changing patterns of IV drug use prevalence, AIDS prevalence among IVDUs, needle-related AIDS risk, polydrug use, sexual risk among IVDUs, and the drug subculture. Finding that ethnic culture does matter in infection patterns and risk behavior, this paper examines a typology for the analysis of discontinuities in intercultural communication and presents a framework for comparing alternative models for overcoming cultural barriers to effective AIDS education with IVDUs.

Utilization of formal and informal home care by AIDS patients in Boston: a comparison of intravenous drug users and homosexual males.

The assumption that intravenous (i.v.) drug users have weaker informal support networks than homosexual men has led to opposing policy recommendations: one emphasizes outreach and more formal (paid) home care for i.v. drug users, whereas the other maintains that formal home care programs are less effective for this risk group due to the lack of informal (unpaid) caregivers to coordinate efforts. Data from interviews with a sample of 231 persons with AIDS in the Boston area were used to compare the use of formal and informal home care between the two largest risk groups, homosexual men and i.v. drug users. Multivariate regression analysis was also employed to adjust estimates and to determine the significance of population characteristics in explaining utilization differences. IV drug users received about twice as much formal and informal home care as homosexual men. Controlling for functional status, income and assets, insurance and potential caregiver supply, i.v. drug users obtained significantly fewer formal home care services, but more informal care. Overall, i.v. drug users received a greater number of adjusted home care hours. These findings cast doubt upon the previous assumptions of the literature and suggest that members of both risk groups are appropriate candidates for formal home care services.
