RESUMO
We quantified HIV-1 RNA load in rinses from needles/syringes (N/S) obtained at shooting galleries in Miami and also analyzed the rinses for antibodies for viral proteins. In rinses from 36 N/S that contained visible blood, 14 (39%) had detectable amounts of HIV-1 RNA. Numbers of copies of HIV-1 RNA ranged from the detection limit (400 copies/ml) to 268,000 copies/ml. We also detected antibodies to HIV-1 polypeptides in 34/36 (94%) of rinses from visibly contaminated N/S using Western blots specific for the HIV-1 proteins. No antibodies were detected in laboratory rinses from six visibly clean needles. The presence of HIV-1 RNA in N/S is an important indication of the risk created by N/S sharing as well as by shared paraphernalia and wash waters by injecting drug users.

Because high rates of drug use have been documented in the migrant farm worker population, the National Institute on Drug Abuse funded the Migrant Health Study to examine HIV risk behaviors among drug-using farm workers and their sexual partners. Many of these individuals were home-based in South Florida and migrated during the work season to various points along the Eastern Migratory Stream. The focus of this paper is a description of the characteristics and behaviors of the 151 respondents contacted on the DelMarVa Peninsula during 1994 and 1995. The data indicate that drug use was widespread in this population, a significant proportion were at risk for HIV infection, and 6% were HIV positive. As a result of these findings, public health agencies on the peninsula have instituted HIV education programs in those clinics utilized by both local and transient agricultural workers.

Publicly funded drug-user treatment programs in both urban and rural areas are under unprecedented pressure to adapt to multiple perspectives of their mission, reduced governmental funding, diminished entitlement program resources for clients, managed care reforms, and continuing unmet need for services. This article describe an ongoing health services research study that is investigating how these and related health and human service programs currently serve and cross-refer chronic drug users and how they perceive and are reacting to systemic pressures. Interim analysis on intra-agency diversity and managed care perceptions are reported.

Shared use of injection equipment (needle/syringes), registering, booting, and backloading are practices among injection drug users (IDUs) that increase the risk for transmission of human immunodeficiency virus type 1 (HIV-1). The sharing of injection paraphernalia (including cookers and cottons) and washwater for rinsing used needle/syringes and dissolving drugs could be potential sources for secondary transmission of HIV-1. Laboratory rinses were made from needle/syringes, cottons, and cookers obtained from shooting galleries, and washwaters were obtained from shooting galleries in Miami. Three rinses were analyzed and antibodies to HIV-1 proteins were detected by using Western blot and HIV-1 DNA was detected by using nested polymerase chain reaction (PCR) specific for the gag and envelope genes of HIV-1. Antibodies to HIV-1 proteins were detected in 12 (52%) of 23 rinses from visibly contaminated needle/syringes, in three (18%) of 17 rinses from cottons, in three (14%) of 21 rinses from cookers, and in one (6%) of 17 washwaters. No antibodies were detected in laboratory rinses from visibly clean needles. Using nested PCR followed by Southern blot confirmation of the amplified targets, HIV-1 gag gene DNA was detected in 16 (84%) of 19 and envelope gene DNA in 17 (85%) of 20 laboratory rinses from visibly contaminated needle/syringes. We detected gag and envelope gene DNA, respectively, in three (27%) and four (36%) of 11 cottons, in six (46%) and seven (54%) of 13 cookers, and in five (38%) of 13 and in 10 (67%) of 15 washwaters from shooting galleries. No HIV-1 DNA was detected in laboratory rinses from visibly clean needles. These results indicate that HIV-1 might be present in contaminated cottons, cookers, and washwaters as well as in contaminated needle/syringes at shooting galleries. Reduction of risks of exposure to HIV-1 among IDUs may require modification of behaviors that are ancillary to the act of injection, such as the use of common cookers, cottons, and washwater.

Recent federal health financing and health care delivery programs have increased access to alcohol and other drug abuse treatment programs for low-income women, and have provided intervention and prevention services for their children and families. The Village South Families in Transition (FIT) in Miami, Florida, implemented a residential treatment program for women and their children that aims to decrease alcohol and other drug use, reduce reliance on social and health welfare systems, improve functioning in specific life-skill and vocational areas, improve parenting techniques and maternal/child relations, and provide intervention and prevention services for the clients' children in a safe and supportive environment. Program implementation required resolutions to numerous barriers, including securing a facility for women and children; recruiting, hiring and training of staff; establishing and maintaining community linkages; treatment considerations; balancing treatment versus evaluation/research; and critical decisions faced by treatment staff as they modify client-centered programs to incorporate gender-specific and family-centered programs.

In the United States, a major federally-funded approach to HIV-1 prevention for injecting drug users (IDUs) includes teaching them to always rinse their needles/syringes with household bleach and water before use. This report describes interdisciplinary studies of the extent to which HIV-1 can be found in injection equipment and the efficacy of bleach as a disinfectant, under simulated field conditions. Bloody needle/syringe units collected from Miami, Florida, shooting galleries or from community outreach prevention participants were selected for these studies. Groups of needle/syringe units were cleansed with bleach using a standard technique taught to IDUs in community outreach programs. Cleansed and uncleansed groups of needles/syringe units were then tested for the presence of HIV-1. The data demonstrate the efficacy of bleach rinses in reducing the risks of HIV-1 infection from needle/syringe units and indicate that the teaching of a bleach cleansing method to IDUs should be part of a total AIDS prevention protocol.

To evaluate the effectiveness of bleach disinfection of injection equipment, we tested HIV-1 inactivation by household bleach in needles and syringes. We obtained blood from HIV-1 infected injecting drug users (IDUs), placed small aliquots in needles and syringes. Blood with and without anticoagulant was incubated at room temperature for 3, 6, 18, and 24 h, and some needles and syringes from each condition were exposed to undiluted bleach for 15 and 30 s. The needles and syringes were then rinsed and the rinses were used to inoculate peripheral blood mononuclear cells (PBMNCs). HIV-1 replication was monitored using p24 enzyme linked immunosorbent assay (ELISA). We describe results that HIV-1 is inactivated in clotted and unclotted blood allowed to stand at room temperature for 3, 6, 18, and 24 h in needles and syringes using undiluted household bleach at 30 s of exposure time. These results are consistent with earlier findings that micropellets of HIV-1 were inactivated by bleach under similar conditions of exposure to bleach; 10% bleach was not effective at an exposure time of 30 s and undiluted bleach was not effective at an exposure time of 15 s to inactivate HIV-1 in clotted blood. Bleach concentration and exposure time are critical and HIV disinfection may not occur with inadequate exposure to bleach HIV.

Bleach cleansing of injection equipment has been recommended to reduce the risk of human immunodeficiency virus (HIV) transmission associated with the reuse of injection equipment by injecting drug users (IDUs). We evaluated the recall and performance of the most commonly recommended bleach cleansing procedure of two complete fillings of the syringe with bleach, followed by two complete fillings with rinse water, and not putting used bleach and water back into source containers. IDUs were taught this procedure on enrollment in an HIV prevention demonstration project in Dade County, Florida. During follow-up session 6-12 months after initial training, the knowledge and ability of IDUs to perform bleach cleansing were assessed by trained observers using a standardized method. In 1988-90, we assessed the knowledge and ability of 450 IDUs to perform the bleach cleansing procedure taught at enrollment. More than 90% of IDUs assessed performed the basic steps. However, only 43.1% completely filled the syringe with bleach and only 35.8% completely filled the syringe with bleach at least twice. Substantial proportions of IDUs did not perform all the steps of the previously taught bleach cleansing procedure. Compliance decreased as the number of steps required was increased. This limited compliance may make bleach cleansing less effective and suggests that some IDUs may fail to adequately disinfect injection equipment and therefore sterile needles and syringes are safer than bleach-cleansed ones. Compliance testing can help assess the effectiveness of HIV prevention programs.

The purpose of this paper is to examine the extent of Dilaudid use and characteristics of users in a population of individuals admitted to drug treatment programs over a four-year period. It was found that the number and rate of Dilaudid use had increased from 1% of those admitted in 1974 to 10% in late 1977. In comparison to other drug users, Dilaudid users were more likely to be white and middle-class. Dilaudid users were also likely to use the drug intravenously and to obtain it by street buys and to also use heroin. Data suggest that Dilaudid use is easily integrated into a heroin-using life style and may serve as a heroin substitute, and that Dilaudid users are a population that has characteristics similar to the type described as the Southern addict.
