Maternal and neonatal seroprevalence of human immunodeficiency virus antibodies in Benin City, Nigeria.

The prevalence of human immunodeficiency virus antibodies in mothers and their neonates was determined through unlinked anonymous HIV testing at delivery. Two hundred and forty-six apparently healthy volunteer anonymous parturients at the University of Benin Teaching Hospital, Nigeria, and their neonates were recruited for the study. Blood samples were collected from the mothers and cord blood from their neonates at delivery. The blood samples were coded and assayed for HIV antibodies using ImmunoComb HIV 1 and 2 bispot test and ImmunoComb II HIV-1 and 2 CombFirm, both from PBS Orgenics, France. The results for maternal and neonatal blood sample pairs were matched. The maternal seroprevalence for HIV antibodies was 2.4% (6/246) while only two infants had HIV antibodies. The mother-to-child transmission of HIV antibodies was 33.3%. The study highlights the increasing HIV infection among pregnant women in this hospital. The risk of vertical transmission is therefore high. Universal antenatal HIV testing with an opt-out system is suggested. The need for our maternity centres and special care baby units to establish management protocols and anti-retroviral therapy for HIV infected women and their neonates is recommended.

Trial of anonymous versus confidential human immunodeficiency virus testing.

Before December, 1986, all public human immunodeficiency virus (HIV) testing in Oregon was done confidentially (using names). In December, clients were offered the option of either anonymous or confidential services. As judged by questionnaire responses, the availability of anonymity increased overall demand for testing by 50%: 125% for homosexual/bisexual (gay) men, 56% for female prostitutes, 17% for intravenous drug users, and 32% for other clients. The number of gay clients who had tests increased from a mean of 42 per month during the 4 months before anonymity was available to 108 per month during the 4 months after, whereas, at public sites in Colorado or California and private sites in Oregon, the number of gay clients tested did not increase. Twice as many seropositive persons were identified during the 3 1/2 months after anonymity became available (n = 85) as in the 3 1/2 months before (n = 36). Thus, availability of anonymous HIV testing and counselling drew gay men who had not sought services under a confidential testing system.

Trends of HIV-1 and sexually transmitted diseases among pregnant and postpartum women in urban Malawi.

OBJECTIVES: To examine rates of HIV-1 and sexually transmitted disease (STD) among pregnant and postpartum women in urban Malawi, Africa. DESIGN: Serial cross-sectional surveys and a prospective study. METHODS: Three major surveys were conducted in 1990, 1993 and 1994/1995. Consecutive first-visit antenatal women and women giving birth at the Queen Elizabeth Central Hospital were tested for HIV and STD after counseling and obtaining informed consent. Unlinked, anonymous HIV testing was also conducted on smaller samples of antenatal women in the same hospital to provide annual prevalence data. HIV-seronegative postpartum women from the 1990 and 1993 surveys were enrolled in a prospective study to determine HIV incidence. RESULTS: HIV seroprevalence rose from 2.0% in 1985 to 32.8% in 1996, a 16-fold increase. The highest age-specific HIV prevalence was in the following age-groups: 20-24 years during 1990, 25-29 years during 1993, and 30-34 years during 1996. Among 1173 women followed for a median of 30.9 months, HIV incidence was 5.98 per 100 person-years in women aged < 20 years and declined steadily in older women. The prevalence of STD significantly declined among both HIV-positive and negative women. This decline in STD prevalence, however, was not accompanied by increased condom use over time. CONCLUSIONS: Among urban childbearing women in Malawi, incidence of HIV is highest among young women while, currently, prevalence is highest among older women. Recent declines in STD prevalence suggest that HIV prevention programs are having an impact either through improved STD diagnosis and treatment or reduced risk behaviors. Sequential cross-sectional STD prevalence measures may be useful in monitoring effectiveness of STD and HIV prevention activities.

Incidence and prevalence of herpes simplex virus type 2 infection in persons seeking repeat HIV counseling and testing.

BACKGROUND: Voluntary HIV testing sites provide an opportunity to identify and counsel persons with herpes simplex virus type 2 (HSV-2) infection, thereby enhancing the prevention of HSV-2 and HIV infections. GOAL AND STUDY DESIGN: Using serologic specimens left over from HIV testing, we measured HSV-2 prevalence and incidence among persons who had repeatedly tested for HIV at anonymous counseling and testing sites in San Francisco during the period October 1997 through March 2000. RESULTS: The prevalence of HSV-2 infection was 23.5% (n = 987) overall, 28.7% among women, and 24.1% among men who have sex with men (MSM). In relation to race/ethnicity, HSV-2 prevalence was highest among African Americans (34.4%). The incidence of HSV-2 infection (n = 457 person-years [PY] of follow-up) was 2.6 per 100 PY overall and 3.1 per 100 PY among MSM. All but one of the HSV-2 seroconversions occurred among MSM. In multivariate subanalysis of MSM, a self-reported sexually transmitted disease (hazards ratio [HR], 4.3; 95% CI, 1.2-16.1) and HIV seroconversion (HR, 19.4; 95% CI 3.8-99.9) during the interval between tests were correlated with HSV-2 incident infection. CONCLUSION: Offering HSV-2 serologic counseling and testing at HIV counseling and testing sites might help prevent the spread of both infectious diseases.

HIV seroincidence among patients at clinics for sexually transmitted diseases in nine cities in the United States.

Although the numbers of newly reported diagnoses of AIDS decreased in the 1990s, it is not clear whether they reflect a decreasing number of new HIV infections. Direct measurement of HIV incidence through follow-up cohort studies is difficult and costly. We estimated HIV incidence and trends in incidence among men who have sex with men (MSM) and heterosexual men and women at clinics for sexually transmitted diseases (STDs) by using a recently developed serologic testing algorithm that requires only a single blood specimen. Cross-sectional anonymous serosurveys were conducted at 13 STD clinics in nine cities in the United States from 1991 through 1997. Before anonymous HIV testing, demographic and clinical information was abstracted. Of 129,774 specimens tested, 362 (0.28%) were from persons estimated to be recently infected. Incidence among MSM was 7.1% (95% confidence interval (CI): 4.8-10.3), 14 times higher than that among heterosexuals, which was 0.5% (CI: 0.4- 0.7). Incidence among MSM and heterosexuals remained unchanged during the time studied. Decreasing rates of new AIDS diagnoses in the 1990s do not reflect stable rates of new HIV infections among MSM and heterosexual patients attending these clinics.

Evaluating the accessibility of HIV testing organizations.

Consumer-based indicators were developed to evaluate the accessibility of private and public nonhospital HIV testing organizations. A comprehensive roster of 148 nonhospital HIV testing organizations in Los Angeles County was constructed from publicly available listings. A telephone survey protocol was used to contact sites and assess consumer relevant accessibility measures. Only 50% of the sites could be contacted and indicated that HIV testing was available. Hence, a consumer who tried to reach one site had only a 50-50 chance of success. HIV testing sites differed with regard to how frequently they offered testing; whether they offered anonymous and/or confidential testing; what types of counseling they provided; how quickly test results were available; and how friendly, helpful, attentive, and knowledgeable about testing procedures their attendants were. HIV testing sites must make their services accessible and be perceived by consumers as responsive if they are to be effective service providers.

Gonorrhoea screening in general practice: perceived barriers and strategies to improve screening rates.

OBJECTIVE: To investigate perceived barriers to gonorrhoea screening in general practice and suggest strategies to overcome them. DESIGN: Questionnaire-based survey. SETTING AND PARTICIPANTS: All 47 general practitioners (GPs) authorised to prescribe subsidised HIV drugs under the Pharmaceutical Benefits Scheme in inner, eastern and northern Sydney. MAIN OUTCOME MEASURES: Agreement on a five-point Likert scale with statements about attitudes and practices in relation to gonorrhoea screening of homosexually active men, and views on how testing rates could be increased. RESULTS: 32 GPs responded (68%). Perceived barriers to gonorrhoea testing included structural measures imposed by the Federal Government to limit pathology testing by GPs (the Medicare "three-test rule") (17 respondents agreed or strongly agreed), pressure from the Health Insurance Commission (HIC) to minimise pathology testing (15), concerns about confidentiality of notification procedures (8), clinical time pressure (8), and concerns about recriminations against HIV patients with gonorrhoea (6). Suggested measures to increase testing were education of gay men to request testing (25), relaxation of the three-test rule (25), easier tests (23), anonymous notification procedures, review of HIC policy on screening, and training about testing (21 each). CONCLUSIONS: Sydney GPs with high HIV caseloads perceived structural barriers to gonorrhoea testing and supported a range of achievable strategies to overcome these. As the sustained epidemic of gonorrhoea in Sydney may be directly promoting HIV transmission, these strategies should be considered urgently.

HIV serosurveillance of newborns. A clinician's perspective on legislative, political, and ethical issues.

This article reviews the complex issues surrounding the anonymous HIV testing of newborns to monitor the prevalence of HIV infection in women of childbearing age. This serosurveillance of newborns has become a topic of legislative debate focusing on disclosure of currently anonymous results of HIV antibody tests of newborns, thus revealing the serostatus of the mother. This, in effect, would mandatorily test women without their consent. The discussion includes the following topics: (a) the historical demographics of incidence rates of AIDS, (b) current political and legislative issues raised by serosurveillance, (c) professional and ethical issues confronting health care providers, and (d) why HIV testing of newborns is a mandatory testing of all women of childbearing age. It is recommended that principles of patients right of self-determination be respected, that mandatory testing would be counterproductive and would disproportionately impact on minorities. The integration of education, counseling, and voluntary testing will result in the most effective way to get both women and children into the health care system.

HIV in women.

There are three patterns of HIV infection and AIDS. In industrial countries infection is between homosexual and bisexual males and intravenous drug users. Relatively few women are infected but the numbers are increasing. In sub-Saharan Africa the infection is heterosexual. More women are infected. AIDS incidence in other countries is low. Twenty-five percent of babies born to HIV positive women will be infected. Testing of infants at birth is difficult because of placental transmission of antibodies. Anonymous antenatal testing is important to establish prevalence which varies greatly in different areas. HIV infection is unique because of the social stigma, lack of vaccine and lack of effective therapy. There are profound social and psychological implications for the woman, her partner and her family. Therefore, a high level of caring and mature professionalism is required by all involved staff.

The prevalence of common BRCA1 and BRCA2 mutations among Ashkenazi Jews.

Three founder mutations in the cancer-associated genes BRCA1 and BRCA2 occur frequently enough among Ashkenazi Jews to warrant consideration of genetic testing outside the setting of high-risk families with multiple cases of breast or ovarian cancer. We estimated the prevalence of these founder mutations in BRCA1 and BRCA2 in the general population of Ashkenazi Jews according to age at testing, personal cancer history, and family cancer history. We compared the results of anonymous genetic testing of blood samples obtained in a survey of >5,000 Jewish participants from the Washington, DC, area with personal and family cancer histories obtained from questionnaires completed by the participants. In all subgroups defined by age and cancer history, fewer mutations were found in this community sample than in clinical series studied to date. For example, 11 (10%) of 109 Jewish women who had been given a diagnosis of breast cancer in their forties carried one of the mutations. The most important predictor of mutation status was a previous diagnosis of breast or ovarian cancer. In men and in women never given a diagnosis of cancer, family history of breast cancer before age 50 years was the strongest predictor. As interest in genetic testing for BRCA1 and BRCA2 in the Jewish community broadens, community-based estimates such as these help guide those seeking and those offering such testing. Even with accurate estimates of the likelihood of carrying a mutation and the likelihood of developing cancer if a mutation is detected, the most vexing clinical problems remain.

Designing an HIV counseling and testing program for bathhouses: the Seattle experience with strategies to improve acceptability.

Bathhouses are important venues for providing HIV counseling and testing to high-risk men who have sex with men (MSM), yet relatively few bathhouses routinely provide this service, and few data are available to guide program design. We examine numerous logistic considerations that had been identified in the HIV Alternative Testing Strategies study and that influenced the initiation, effectiveness, and maintenance of HIV testing programs in bathhouses for MSM. Key programmatic considerations in the design of a bathhouse HIV counseling and testing program included building alliances with community agencies, hiring and training staff, developing techniques for offering testing, and providing options for counseling, testing, and disclosure of results. The design included ways to provide client support and follow-up for partner notification and treatment counseling and to maintain relationships with bathhouse management for support of prevention activities. Early detection of HIV infection and HIV prevention can be achieved for some high-risk MSM through an accessible and acceptable HIV counseling and testing program in bathhouses. Keys to success include establishing community prevention collaborations between bathhouse personnel and testing agencies, ensuring that testing staff are supported in their work, and offering anonymous rapid HIV testing. Use of FDA approved, new rapid tests that do not require venipuncture, centrifugation, or laboratory oversight will further decrease barriers to testing and facilitate implementation of bathhouse testing programs in other communities.
