Intravenous drug users who present to the Albion Street (AIDS) Centre for diagnosis and management of human immunodeficiency virus infection

Intravenous drug users who presented to the Albion Street (AIDS) Centre for human immunodeficiency virus (HIV) antibody screening during the period March 1, 1985 to January 31, 1989, were included in this study. Information on medical history and HIV risk-related behaviour was collected by means of a standardized, computer-coded medical record. Of the 1222 intravenous drug users in this study, 72.3% were men, 26.9% were women and 0.8% were transsexual, with 60.1% of the total claiming exclusive heterosexuality. Of the sample, 40.2% were current intravenous drug users, and 86.8% recorded having shared needles and syringes. Among this sample, the over-all prevalence of HIV seropositivity was 14.5%. Of subjects who were diagnosed as HIV seropositive, 43.8% were homosexual men, 13.1% were bisexual men and 5.3% were heterosexual men. Of all intravenous drug users, 49.9% had a history of at least one sexually-transmitted disease, with 21.8% reporting a history of more than one. Fifty-two per cent of the sample reported that they had been infected with hepatitis B previously. There was no over-all increase in the annual rate of HIV infection among this population of intravenous drug users. The sexual activity and prevalence of hepatitis and other sexually-transmitted diseases among this group are suggestive of widespread, continuing risk behaviour.     

HIV risk behaviour among injecting drug users in Perth: the Australian National AIDS and Injecting Drug Use Study.

OBJECTIVE: This study was carried out in 1989 to examine behaviour involving risk of human immunodeficiency virus (HIV) infection and to measure the prevalence of HIV antibodies in a sample of injecting drug users (IDUs) in Perth. DESIGN: The study was a cross-sectional survey with a sample of convenience of 196 IDUs drawn from drug treatment (54%) and non-treatment (46%) populations. RESULTS: Sixty-five per cent of the sample were men and 35% women. Subjects were predominantly heterosexual, were in their late twenties, had not completed secondary school, and were on sickness, unemployment or pension benefits. The majority were poly-drug users, but heroin and amphetamines were the only drugs that had been injected by more than 20% of the sample more than once a month. Respondents reported injecting an average of 43.6 (SD 83.6) times a month and using 33.7 (SD 55.4) new needles a month. The majority (70%) had injected within weeks of the interview. Sixty-seven per cent had shared needles within months. Respondents claimed to pass on used needles more frequently than to accept them, and were most likely to share with close friends or lovers when clean needles were unavailable and/or when they were withdrawing. While most respondents cleaned used needles, few used bleach all or most of the time. Most (78%) respondents had been tested for HIV seropositivity at least once. Most had multiple sexual partners and 92.3% had engaged in at least one unsafe sexual practice during the previous six months. Sixty-four per cent had changed some aspect of drug using, and 38% some aspect of sexual behaviour since hearing about the acquired immunodeficiency syndrome (AIDS). HIV seroprevalence for the 179 respondents who were tested was 2.2%, but this figure should not be taken as an estimate of seroprevalence for the Perth IDU population. CONCLUSION: Respondents' behaviour placed them at a high level of risk for HIV infection. Based on reported behaviour, it is recommended that education for IDUs in Perth should emphasise, among other things: not passing on used needles; cleaning used needles and syringes with bleach; planning ahead so that sterile equipment is available; and further risk reduction, particularly the adoption of safer sexual practices.

Sexual practices in the transmission of hepatitis B virus and prevalence of hepatitis delta virus infection in female prostitutes in the United States.

OBJECTIVE--To evaluate heterosexual transmission of hepatitis B virus (HBV) and the prevalence of hepatitis delta virus (HDV) infection in female prostitutes. DESIGN--Survey. SETTING--Sexually transmitted disease clinics, drug treatment programs, detention centers, and/or outreach efforts in eight areas in the United States. PARTICIPANTS--A total of 1368 female prostitutes 18 years of age or older. OUTCOME MEASURES--Seropositivity for HBV and HDV infection. RESULTS--The overall prevalence of past or present HBV infection was 56%: 74% in women who were injecting-drug users (IDUs), 38% in women reporting no history of injecting-drug use (non-IDUs), 51% in whites, 55% in blacks, and 67% in Hispanics. Of 21 HBV carrier IDUs, 21% had HDV infection; of 18 HBV carrier non-IDUs, 6% had HDV infection. In non-IDUs (49%), risk factors for HBV infection were a history of having penile-anal intercourse (odds ratio [OR], 3.1; 95% confidence limits [CL], 1.3, 7.3) and seropositivity for syphilis and human immunodeficiency virus (HIV) infection. In IDUs, factors associated with an increased risk of infection, in addition to behaviors related to injecting-drug use, were the number of lifetime sexual partners, having sexual partners from groups at high risk for HBV infection, and seropositivity for syphilis and HIV infection; spermicide and/or diaphragm use was associated with a markedly decreased risk of HBV infection among blacks (OR, 0.1; 95% CL, 0.03, 0.4) and Hispanics (OR, 0.2; 95% CL, 0.06, 0.9). CONCLUSION--This is the first study to suggest that having anal intercourse and failing to use vaginal contraceptives may facilitate transmission of HBV to women. Our data support guidelines that recommend hepatitis B vaccination for prostitutes and persons with a history of sexually transmitted diseases or multiple sexual partners.     

不同方式招募的吸毒者高危行为和HIV、HCV及梅毒感染的比较

目的比较不同方式招募的吸毒者社会人口学、高危行为及HIV、HCV和梅毒感染情况。方法于2004年5~7月,从四川省凉山彝族自治州西昌市社区中招募吸毒人群调查其社会人口学特征、近3个月直接和间接共用注射器具静脉吸毒方式、近6个月性行为情况。采集研究对象的血样进行HIV、HCV和梅毒抗体检测。结果在招募的451名吸毒者中,通过同伴招募和其他方式招募的分别占73.8%和26.2%。性别、民族、年龄、文化程度和婚姻状况在不同方式招募的吸毒者中差异有统计学意义。静脉注射吸毒频率、口吸海洛因频率、海洛因混合其他毒品使用频率、共用针头或注射器频率、共用洗针头或注射器用水频率、共用吸毒器皿频率、共用棉球频率、共用注射器前或后装入毒品频率、以及与固定性伴/临时性伴非保护性性行为、以性交为条件给性伙伴提供钱物和新的性伙伴在不同方式招募的吸毒者中差异有统计学意义。未见不同方式招募的吸毒者HIV、HCV和梅毒感染差异有统计学意义。结论应答驱动抽样是招募吸毒人员的有效方法,通过同伴容易招募到少数民族和高危行为的吸毒者。     

Prevalence of HIV infection in provincial prisons in British Columbia.

OBJECTIVE: To ascertain the prevalence of HIV infection among people entering provincial adult prisons in British Columbia and to study associations between HIV infection and specific demographic and behavioural characteristics. DESIGN: Prospective, unlinked, voluntary survey involving HIV antibody testing of saliva specimens. SETTING: All adult provincial prisons in British Columbia through which inmates are admitted to the provincial correctional system. PARTICIPANTS: All adult inmates admitted to provincial prisons in British Columbia between Oct. 1 and Dec. 31, 1992. OUTCOME MEASURES: Rate of HIV positivity. Independent variables included sex, native status (native or non-native), self-reported HIV status, age group and history of injection drug use. RESULTS: A total of 2482 (91.3%) of 2719 eligible inmates volunteered for testing. Refusal was not associated with sex, native status, self-reported HIV status or age group; inmates who reported a history of injection drug use were more likely than the others to refuse HIV antibody testing (12.9% v. 6.8%; p < 0.001). The 2482 inmates who were tested for HIV were similar to the general inmate population with regard to sex, native status and age group. A total of 28 inmates were confirmed to be HIV positive, for an overall prevalence rate in the study population of 1.1% (95% confidence interval 0.8% to 1.6%). The prevalence rates were higher among the women than among the men (3.3% v. 1.0%; p = 0.023, Fisher's exact test) and among the inmates who reported a history of injection drug use than among those who did not report such a history (2.4% v. 0.6%; p < 0.001). There was no association between HIV status and native status or age group. Logistic regression analysis revealed the higher prevalence rate among the women to be explained by more of the women than of the men reporting a history of injection drug use. Of the 30 people who stated that they were HIV positive and who were tested, 19 (63.3%) had a negative result; conversely, 17 who reported that they were HIV negative or had not been tested had a positive result. CONCLUSIONS: Unlinked, voluntary HIV antibody testing of inmates can achieve high participation rates. The overall prevalence rate of 1.1% and the rate among the female inmates of 3.3% confirm that HIV infection is a reality in prisons and that the virus has established a clear foothold in inmate populations. Harm-reduction interventions should include a comprehensive education program for inmates on infectious diseases, the availability of condoms throughout prisons and the distribution of bleach for sterilizing needles and syringes. From a public health perspective, these data suggest an urgent need for access to sterile injection equipment in addition to other preventive measures.     

重庆市200名女性劳教人员艾滋病知识及高危行为特征分析

目的了解女性劳教人员中梅毒、艾滋病的患病率和关于STD/AIDS的知识、态度、信念和行为(KABP)情况,为探索有效的行为干预措施提供科学的依据.方法对重庆市女子劳教所中新入所的200名女性劳教人员进行有关STD/AIDS的KABP问卷调查,资料经SPSS9.0进行统计分析.结果在200名劳教人员中共查出梅毒48例,患病率为24.0%,HIV感染者8例,患病率为4.0%,经静脉吸毒仍为主要的感染途径.对艾滋病性病的认知水平较高,但与性伴侣发生性关系时安全套使用率低,每次都用安全套的仅占15.5%.与性伴侣发生性关系时不用安全套的主要原因是性伴侣不喜欢.结论梅毒在吸毒人员和卖淫妇女中的高患病率和HIV的流行,预示艾滋病正由吸毒人群向性乱人群蔓延,加强吸毒人群和性滥交者的综合监测和行为干预已迫在眉睫.     

合肥市青年男男性行为者梅毒和HIV感染状况分析

目的了解合肥市青年男男性行为者(MSM)梅毒和HIV感染状况以及相关的因素,为对该人群进行梅毒与HIV预防干预提供依据。方法采用应答者驱动招募、关键知情人介绍及在MSM网站上发布广告三种方法招募年轻的男男性行为者,进行匿名问卷调查与HIV和梅毒血清学检测。结果202名调查对象平均年龄为20.7岁,大学及以上学历占66.9%,在校学生为62.4%,63.4%的人自认为是同性性取向,26.7%的人自认为是双性性取向。HIV感染率为1.0%,RPR阳性率为7.0%,TPPA阳性率为13.1%。单因素2检验表明,曾进行过HIV检测、一生中肛交同性性伴4个以上与梅毒感染相关,2值分别为10.944与7.696(均P<0.01)。结论年轻的男男性行为者中梅毒感染情况严重,HIV在该人群中流行条件已经具备,急需在该人群中开展性病艾滋病的高危行为干预,尤其要加强大、中学校学生性病艾滋病知识宣传和健康教育。
