The epidemiology of HIV infection and AIDS in east and central Harlem, NY.

This report describes the AIDS epidemic in East and Central Harlem, among the hardest-hit communities in the nation. Information was obtained from two New York State mandatory reporting programs: anonymous HIV antibody testing of newborns, and physician and hospital reports of AIDS cases to city and county public health departments. One of 30 babies born in East Harlem and one of 46 newborns in Central Harlem are seropositive. The cumulative rate of reported AIDS cases in these communities is 10-15 times the national rate, and together, the communities reported 1.3% of all AIDS cases in the nation, although they have only 0.1% of the nation's population; 2.2% of all childhood AIDS cases have been reported from East and Central Harlem. Women, minorities, and injection drug users comprise a higher proportion of the cases than in the city, the state, and the nation. The consequences of the epidemic in these communities are enormous, including profound stresses on community institutions and exacerbation of the resurgence of tuberculosis.

Study of the knowledge, beliefs, and practice of sleep among medical undergraduates of Tamilnadu, India.

CONTEXT: Sleep-related problems are common in young adults who are enrolled in professional colleges due to academic and social pressures, which may subsequently have serious consequences. OBJECTIVES: This study was conducted to find out whether final-year medical undergraduates possess basic, clinically relevant knowledge (K) regarding sleep and sleep-related problems and to discover their beliefs (B) regarding sleep and sleep hygiene. We also wanted to assess their sleep practices (P) and suggest remedial measures, if necessary. DESIGN AND SETTING: Six hundred fifteen final-year medical undergraduates of both sexes belonging to 6 medical colleges of Tamilnadu state, India, were given a self-administered, anonymous questionnaire to test their basic knowledge (11 items), prevailing beliefs regarding sleep (including sleep hygiene [13 items]), and their sleep practices (6 items). RESULTS: In all 3 domains tested (K, B, and P), there was no significant difference between sex. An appreciable percentage scored < or = 70% marks ("good") only in K and P (63.9% and 79.5% of all participants, respectively), whereas only a very small percentage scored "good" in B (9.1%). There was no difference in K, B, or P in terms of sex or domiciliary status except for a significant difference (P < .012) regarding beliefs between urban and rural groups. There was also no correlation between knowledge and beliefs or between knowledge and practice. CONCLUSION: We conclude that future doctors have insufficient knowledge with more misconceptions (indirectly reflecting inadequate knowledge) regarding sleep. Hence, there is a compelling need to develop an educational strategy to overcome misconceptions and improve knowledge regarding sleep-related problems and proper sleep practices among students.

HIV-2 in the United Kingdom--a review.

Human immunodeficiency virus type 2 (HIV-2) was first recognised in 1986 and subsequently the infection was shown to be widespread in West Africa. There have been few case reports from countries outside the African continent. In North America and Europe the highest number of infections have been in Portugal and France. Twelve HIV-2 infections have been identified in the United Kingdom (UK) and nine of the twelve had some connection with Africa, mostly West Africa; in three cases only "sub-Saharan Africa" was stated on the report, and one was from Mozambique. The other three HIV-2 infections were identified as follows: one in stored sera from a man who died in 1978, one in a child from Portugal who was diagnosed in the UK as having Acquired Immune Deficiency Syndrome (AIDS) in 1985, and one in a homosexual man who was tested unlinked and anonymously in London in 1987. It is not known how many of the total number of UK HIV-2 infections are represented by these twelve, but among large numbers of blood donors and people attending genitourinary medicine clinics the occurrence of infection was rare.

The unlinked anonymous HIV prevalence monitoring programme in England and Wales: preliminary results.

Results are presented from unlinked anonymous HIV-1 testing of specimens collected during 1990 from 8996 genito-urinary medicine clinic attenders, 1421 injecting drug users, and 69,091 pregnant women. One-fifth of homo/bisexual men attending London genito-urinary medicine clinics were infected with HIV-1. The figure was 4% outside London. The prevalence of HIV-1 infection among male heterosexual attenders at genito-urinary medicine clinics who were not known to have injected drugs, was 1% in London and 0.2% outside London. Women attending genito-urinary medicine clinics in London, who were not known to have injected drugs had a prevalence of HIV-1 infection of 0.2% (1 in 440). None of 2045 women attending genito-urinary medicine clinics outside the Thames regions was found to be infected with HIV-1 although one woman was infected with HIV-2. The prevalence rate for HIV-1 infection in injecting drug users was 1.1%. Of those who began injecting between 1986 and 1990, however, 22% had evidence of hepatitis B infection. The prevalence of HIV-1 infection among pregnant women receiving antenatal care was 0.19% (1 in 515) in inner London, 0.07% (1 in 1440) in the rest of the Thames regions and 1 in 16,000 in another region of the country. Two pregnant women, one in inner London and one elsewhere in the Thames regions, were infected with HIV-2. The data suggest that, so far, the epidemic has concentrated among homo/bisexual males, injecting drug users and persons attending genito-urinary medicine clinics, especially in the London area. There are indications that the prevalence of HIV-1 infection is increasing among heterosexuals in inner London.

Methods of surveillance for HIV infection in primary care outpatients in the United States.

Primary care outpatients provide a good sentinel population for monitoring levels and trends of HIV infection in the United States. Because a broad cross section of the population seeks primary medical care, excess blood from specimens routinely collected for other purposes is available for anonymous, unlinked HIV testing, and all age groups and both sexes can be sampled. The CDC family of surveys includes two surveys of primary care outpatients: (a) a survey of 100,000 blood specimens per year submitted by more than 6,000 primary care physicians to a national diagnostic laboratory for complete blood count or hematocrit and (b) a survey of approximately 10,000 blood specimens per year from a network of 242 primary care physicians. Each survey has different advantages: the laboratory-based survey has a large sample from a large population base, and the physician network survey has a well-defined patient population in which each patient's clinical condition can be determined. In the primary care physician network, a concurrent study of clinical patterns of disease in patients with recognized HIV infection provides additional information on the clinical syndromes associated with HIV infection and estimates of the occurrence of unrecognized HIV infection.

Coinfection with tuberculosis and HIV-1 in male prison inmates.

An association between past exposure to tuberculosis (TB) and infection with human immunodeficiency virus type 1 (HIV-1) was investigated using a case-control design among a 6-week sample of 698 male inmates consecutively admitted to the Maryland State prison system. Based on Mantoux testing and measurement of anti-HIV-1, we found a positive but not significant association between HIV-1 and TB infection (odds ratio 2.4, 95 percent confidence interval 0.9-6.3). The power of the study to detect an association of this magnitude was 0.57. Of the entire intake sample, 1.3 percent were found to be coinfected with TB and HIV-1. Some misclassification may have been present due to anergy or latent HIV-1 infection. The elevated risk of TB in coinfected inmates, coupled with the study results, suggest that the inmate screening process on entry to the prison should be modified to improve identification of coinfected people. Specifically, anergy testing should be added to the admission screening procedure, and appropriate voluntary anonymous HIV-1 antibody testing should be more widely available to inmates.

The seroepidemiology of human immunodeficiency virus in the United States household population: NHANES III, 1988-1991.

To provide an estimate of the seroprevalence of human immunodeficiency virus (HIV) in a representative sample of the U.S. household population, serum samples from participants in the third National Health and Nutrition Examination Survey (NHANES III) were tested for HIV antibody. The testing was performed anonymously on 5,430 individuals 18-59 years old from phase 1 of NHANES III conducted from 1988 to 1991. Twenty-nine individuals were HIV positive. The total weighted prevalence was 0.39%. The population estimate of infected individuals was 547,000, with a 95% confidence interval of 299,000-1,020,000 infected persons. Black participants were four times more likely to be HIV positive than white/other individuals and three times more likely than Mexican Americans. Men were three times more likely to be infected than women. Higher nonresponse to the survey and to phlebotomy was observed in young white men; therefore these data provide a conservative estimate of HIV infection in the general household population. This estimate does not include individuals who do not live in households and who may be at higher risk of infection, such as persons in penal institutions, the homeless, or certain hospitalized patients.

The prevalence of chemical substance and alcohol abuse in an obstetric population in Dublin.

OBJECTIVE: To determine the prevalence of illicit drug abuse and alcohol use in an obstetric population based in an urban maternity hospital. SETTING: A collaborative study between the Rotunda Hospital, Dublin and the Irish National Drug Advisory & Treatment Centre. DESIGN: A prospective study consisting of anonymous, unlinked urine testing of 504 'first visit' antenatal patients and a separate group of 515 patients six weeks after delivery. METHODS & OUTCOME MEASURES: Toxicological screening using enzyme-linked immunoassay techniques, with all positive samples being reanalysed. Drug histories were taken and samples were tested for alcohol and six of the most commonly abused drugs. The pre- and postnatal prevalence of abuse was matched with demographic data. RESULTS: The prevalence of chemical substance misuse in the antenatal population was 2.8% and 5.6% in the postnatal population. Substances identified included benzodiazepines, cannabis, amphetamines, opiates and cocaine. Less than 2% of samples tested positive for alcohol. None of the women yielding positive samples had been pre-identified on the basis of history. A significant proportion of the women were in the high risk categories with regard to age and socio-economic status. CONCLUSION: The prevalence of drug misuse antenatally was nearly 3% and postnatally almost 6%. Substance abusers in pregnancy are more likely to be single, unemployed, and to have had a previous pregnancy.

Failure to learn human immunodeficiency virus test results in Los Angeles public sexually transmitted disease clinics.

BACKGROUND: Early human immunodeficiency virus (HIV) defection is essential for initiating treatment and partner-notification activities. Sexually transmitted disease (STD) clinic attendees are at high risk for infection and should be made aware of their HIV status. GOAL: To determine the characteristics associated with not receiving an HIV test result in an STD clinic setting. STUDY DESIGN: Confidential HIV testing was offered to 6,705 persons attending four public STD clinics in Los Angeles who submitted blood for syphilis serology and were tested for HIV antibody in an unlinked HIV serosurvey. Human immunodeficiency virus test results and return status were anonymously linked to other risk information. RESULTS: Only one-third of attendees were tested and given their results. Those testing HIV positive in the anonymous survey and those requesting HIV testing were most likely to receive a test result (i.e., 41% and 49%, respectively). Those solely requesting an STD examination, repeat testers, and African-Americans were least likely to receive a result (i.e., 32%, 30%, and 26%, respectively). CONCLUSIONS: Most STD clinic patients fail to receive an HIV test result. Other strategies, such as rapid HIV testing, are needed to increase participation and receipt of HIV test results in this high-risk population.

Attitude of pregnant women towards HIV testing in Abidjan, Côte d'Ivoire and Bobo-Dioulasso, Burkina Faso. DITRAME Study Group (ANRS 049 Clinical Trial). Diminution de la Transmission Mère Enfant du VIH. Agence Nationale de Recherches sur le SIDA.

OBJECTIVE: To evaluate the attitude of pregnant women towards HIV testing in two cities of West Africa: Abidjan, Côte d'Ivoire and Bobo-Dioulasso, Burkina Faso. METHODS: In the context of a clinical trial to prevent HIV vertical transmission, HIV counselling and testing was offered systematically to women attending antenatal clinics. Informed consent was obtained and test results were given anonymously. Multiple logistic regression was performed to identify factors associated with refusal for testing and failure to return for test results. RESULTS: A total of 9724 pregnant women were interviewed from January 1995 to September 1996. In Abidjan (n=5766) and Bobo-Dioulasso (n=3958), 78 and 92.4% of the women consented to HIV testing, respectively, and 58.4 and 81.8% of them returned for the test results disclosure, respectively. In the two sites, the counsellors themselves and high educational level of the women appeared to be related to refusal of the test, whereas last trimester gestation was associated with failure to return for test results. In Abidjan, foreigners and employees were more likely to refuse testing, and HIV-infected women were three times less likely to return for results than uninfected women. CONCLUSION: Future implementation of interventions to reduce vertical transmission of HIV that require antenatal HIV testing and counselling will have to solve issue of acceptability of HIV testing by pregnant women.

Mobilizing a mass HIV counseling and testing program in Chautauqua County.

In October 1997, the staff of the New York State Department of Health's Anonymous HIV Counseling and Testing Program were mobilized to assist the Chautauqua County Department of Health to respond to an unprecedented demand for HIV counseling and testing. This demand followed the release of the name of an HIV-infected individual who was suspected of infecting 13 young women in Chautauqua County. This article reviews essential elements of New York's efforts to assist Chautauqua County in meeting increased demands for HIV counseling and testing services during the emergency response. New York's experience can help inform other jurisdictions that may encounter similar public health emergencies in the future.

Publicly funded HIV counseling and testing in the United States, 1992-1995.

Data are collected and reported through the Centers for Disease Control and Prevention (CDC) Counseling and Testing System (CTS) on episodes of publicly funded counseling and HIV testing in the Unites States. The objective of this analysis is to describe testing data reported from 1992 through 1995. In 1992, 2,689,056 tests were performed, and 55,024 (2.0%) were positive; in 1995, 2,491,434 tests were performed, of which 40,605 (1.6%) were positive. Among tests reported with client-level data, the proportion of tests of men and women at higher risk for HIV infection remained stable or declined; the proportion of tests of persons who had been previously tested increased each year; and in 1995, the proportion of tests that included posttest counseling was 86% for anonymous and 70% for confidential tests. Although information collected through CTS could be improved by changing the system so that individuals could be distinguished from testing episodes, the CTS does provide important monitoring information to local and state health departments.

Parent and adolescent perceived need for parental consent involving research with minors.

OBJECTIVE: To assess parents' and adolescents' perceived need for parental consent for minor adolescents to participate in minimal risk research studies based on procedural invasiveness (anonymous surveys, interviews, and blood or urine testing) and sensitivity of the topics (sexuality, drug and alcohol use, and sexually transmitted diseases and human immunodeficiency virus [HIV]). METHODS: An anonymous self-report questionnaire was administered to 100 adolescent-parent pairs at 2 clinical sites (urban and suburban) of Children's Hospital of Michigan in Detroit. RESULTS: By invasiveness of the research procedure, the proportions of parents and adolescents who perceived a need for parental consent were as follows: face-to-face interviews, 62% vs 48%; telephone interviews, 72% vs 46%; blood or urine testing, 77% vs 62%; and blood testing for HIV status, 78% vs 59%. These differences were only significant for telephone interviews and HIV blood testing. For anonymous surveys, a minority of parents (33%) and adolescents (26%) reported that parental consent was needed. Based on sensitivity of the research topics, the proportions of parents and adolescents who perceived a need for parental consent were as follows: sexuality, 60% vs 34%; drug and alcohol use, 56% vs 44%; contraception, 62% vs 46%; and sexually transmitted diseases and HIV testing, 56% vs 52%. These differences were only significant for sexuality. Parents with higher education believed that teens could give their own consent (P < .05). Fifty-seven percent of parents and their teens agreed that parental consent for anonymous surveys was not necessary. For more invasive procedures and more sensitive topics, the percentage of disagreement ranged from 28% to 55.5%. CONCLUSIONS: There is a greater perceived need for parental consent to adolescent participation in research studies among parents than among teens for more invasive procedures and more sensitive topics. These results suggest the need for sensitivity to differing adolescent and parental perceived need for parental consent for a minor adolescent to participate in such studies. Further studies with larger samples are needed to determine what factors influence diverse parent and adolescent opinions.

Surveillance of HIV in the army of the Republic of Cyprus (SHARC); rationale, design, and implementation of an inexpensive system.

OBJECTIVES: To design and implement an HIV surveillance system using periodic cross sectional prevalence surveys in National Guard recruits of the Republic of Cyprus. METHODS: HIV infection surveillance used unlinked anonymous screening (UAS) methodology, which tested residual blood originally collected for other purposes. Residual blood from samples collected for ABO blood group typing at intake and samples from blood collected for hepatitis testing at discharge was used. Screening was unlinked and anonymous. RESULTS: The system operated for four semiannual recruitment seasons: summer 1998 to the end of winter 2000. No recruits screened at entry into the ranks tested positive. CONCLUSIONS: This was the first large scale HIV surveillance project in Cyprus. Without nationwide HIV surveys, periodic measurements of prevalence could lead to estimates of HIV incidence and provide insights on temporal changes in HIV infection rates. The prevalence data collected provide useful epidemiological information about the status of the HIV epidemic in this segment of the population in Cyprus.

Testing for HIV without specific consent: a short review.

The practice of testing for human immunodeficiency virus (HIV) without the specific knowledge and consent of the patient raises ethical and legal issues. This report argues that diagnostic HIV testing of specific patients, without their consent, is unethical and may also be illegal. Testing for HIV prevalence on an anonymous, unlinked basis, however, is an important aspect of public health surveillance, and the ethics of clinical intervention should not be confused with the ethics of epidemiological research. Specific consent is usually desirable in view of privacy concerns, the importance of patient autonomy, and the potential for conflict of interest. However, where otherwise appropriate, the law should be clarified to permit nonconsensual HIV testing to proceed legally, possibly following scrutiny by an institutional ethics committee.

Lack of HIV testing and awareness of HIV infection among men who have sex with men, Beijing, China.

In China, men who have sex with men (MSM) are at high risk for HIV. However, little is known about their HIV testing behavior. From September 2001 to January 2002, we recruited 482 men through social networks and MSM venues. We conducted HIV testing and counseling, and anonymous, standardized face-to-face interviews. Eighty-two percent of participants had never tested for HIV before the study. The most common reasons for not testing were perceived low risk of HIV infection (72%), not knowing the location of test sites (56%), fear of positive test results (54%), fear of people learning about his homosexuality (47%), and fear of breach of confidentiality about test results (47%). We identified five statistically significant independent correlates of having been tested for HIV: being older, having a college degree, being more "out" (disclosing MSM activities to people), being recruited through social networks, and having a lifetime history of sexually transmitted diseases. Of 15 participants (3.1%) who tested positive for HIV in our study, 14 (93%) did not know their status before being tested in the study. The prevalence of HIV testing among MSM in Beijing is low; almost all HIV-positive men in our study were unaware of their infection. Our findings suggest an urgent need to promote HIV testing among MSM in Beijing.

HIV infection among pregnant women in Bobo-Dioulasso, Burkina Faso: comparison of voluntary and blinded seroprevalence estimates.

The objective of our study was to estimate the prevalence of HIV infection among pregnant women in Bobo-Dioulasso (Burkina Faso) according to 2 survey methods. Unlinked anonymous HIV screening was performed among women attending 2 antenatal clinics. Voluntary and confidential HIV counselling and testing were offered to women attending 2 other antenatal clinics in the same time period, September-October 1996. Voluntary HIV testing was performed in the context of a clinical trial on mother-to-child transmission of HIV (ANRS 049 clinical trial) with an acceptance rate of HIV testing of 93%. The first survey recruited 200 women and the second, 424. The mean age (24.6 years vs 24.8 years) and the mean number of pregnancies (3.1 vs 3.3) of women were comparable, in the 2 studies (P=0.69 and P=0.26, respectively). Prevalence of HIV infection in the blinded survey was estimated at 10.0% (95% confidence interval (CI): 6.4-15.2), while it was 9.4% (95% CI: 6.9-12.7) in the voluntary HIV screening programme. These 2 estimates were not statistically different (P=0.82). In the voluntary screening study, the prevalence of HIV infection was significantly different between age groups 15-24 years and 25-49 years (13.9% vs 4.5%, P < 0.001). In the age group 25-49 years, the prevalence of HIV infection estimated in the blinded study and in the voluntary screening study were significantly different (10.5% vs 4.5%, P=0.04) suggesting a potential participation bias among pregnant women of older age in the voluntary, confidential HIV screening group. In conclusion, for the purpose of HIV surveillance, the most reliable method for HIV prevalence remains the unlinked, anonymous testing.

[Are we testing the right people? Results of a patient questionnaire in the STD and HIV counselling office of the local health authority in the city of Cologne].

BACKGROUND: HIV testing and counselling is offered free of charge in most local health offices in Germany. During 2003, a survey was performed among German-speaking clients of the Cologne local health office to look at socio-demographic background, reasons for testing and sexual risk behaviour. METHODS: All German-speaking clients attending the HIV counselling office from March to July 2003 were asked to fill in an anonymous standardised questionnaire. Questions included demographic characteristics, social status, STI history, reasons for HIV testing, sexual orientation and number of sexual partners. Data were compared to the general Cologne population regarding demographic characteristics. Female respondents were compared to heterosexual men and men who have sex with men (MSM); German respondents were compared to migrants using SPSS 14.0. RESULTS: A total of 457 female and 488 male clients participated (response rate 93.9 %). Average age was 28.4 years. Of all participants, 17.7 % were of non-German origin. The respondents had a high school degree in 80.8 % of the cases compared to 33.5 % in the general Köln population (p < 0.001). Among men, 30.2 % were MSM. Having a "new partner" or "unprotected sex with a person with unknown HIV status" were reported by 483 (39.8 %) and 373 (30.8 %) as reasons for testing. 38.7 % of the respondents reported choosing the local health office for HIV testing because it was free of charge and 24.5 % because it was anonymous. Women and heterosexual men had a median of 1, MSM a median of 3 sexual partners within the past 6 months (p < 0.001). Vaccination against hepatitis B was reported by 34.4 % of the clients, the proportion was higher among MSM (46.9 % p < 0.001) and lower among migrants. 112 (11.9 %) persons reported having had a previous STI. CONCLUSIONS: With the exception of MSM, the offer of free and anonymous HIV testing and counselling does not reach persons who carry a higher risk for HIV. As the risk for STI is higher than for HIV in Germany and there is a low public awareness, HIV counselling should be used for comprehensive sexual health counselling and include the offer for STI testing, Further outreaching efforts and other settings are necessary to reach persons with a low education level and highly vulnerable persons.
