Epidemiology of HIV infection in women and newborns

Ethical issues in HIV

The number of people with HIV/AIDS continues to increase globally. Women, who represent the subgroup with the fastest rate of increase, are usually informed of their serostatus by the obstetrician/gynaecologist. As treatment of infected women raises a number of ethical issues, an understanding of the theoretical background for ethical decision making is requisite to ensure these problems are resolved within a morally appropriate framework. Vigorous debate has arisen from the tensions between the competing goals of HIV testing, third party disclosure, management of the critically ill HIV-infected woman, infertility management in the background of HIV/AIDS, and gender-based violence as cause or result of acquiring HIV infection. Women may be differently empowered economically, socially and culturally. What may be a satisfactory solution in the context of the USA and Europe may be far from ideal in that of the developing world.

Postexposure prophylaxis in children and adolescents for nonoccupational exposure to human immunodeficiency virus

Exposure to human immunodeficiency virus (HIV) can occur in a number of situations unique to, or more common among, children and adolescents. Guidelines for postexposure prophylaxis (PEP) for occupational and nonoccupational (eg, sexual, needle-sharing) exposures to HIV have been published by the US Public Health Service, but they do not directly address nonoccupational HIV exposures unique to children (such as accidental exposure to human milk from a woman infected with HIV or a puncture wound from a discarded needle on a playground), and they do not provide antiretroviral drug information relevant to PEP in children. This clinical report reviews issues of potential exposure of children and adolescents to HIV and gives recommendations for PEP in those situations. The risk of HIV transmission from nonoccupational, nonperinatal exposure is generally low. Transmission risk is modified by factors related to the source and extent of exposure. Determination of the HIV infection status of the exposure source may not be possible, and data on transmission risk by exposure type may not exist. Except in the setting of perinatal transmission, no studies have demonstrated the safety and efficacy of postexposure use of antiretroviral drugs for the prevention of HIV transmission in nonoccupational settings. Antiretroviral therapy used for PEP is associated with significant toxicity. The decision to initiate prophylaxis needs to be made in consultation with the patient, the family, and a clinician with experience in treatment of persons with HIV infection. If instituted, therapy should be started as soon as possible after an exposure-no later than 72 hours-and continued for 28 days. Many clinicians would use 3 drugs for PEP regimens, although 2 drugs may be considered in certain circumstances. Instruction for avoiding secondary transmission should be given. Careful follow-up is needed for psychologic support, encouragement of medication adherence, toxicity monitoring, and serial HIV antibody testing.

Gender-related psychosocial and cultural factors associated with condom use among Chinese married women

The present study explored the interplay of psychosocial, gender, and cultural factors on Chinese married women's condom use. A total of 433 Chinese married women residing in Hong Kong participated in the study. Correlation results showed that participants' conservative gender attitudes toward sexuality and sexual decision making were related to less accurate HIV/AIDS knowledge and less concern about contacting the disease from their husbands. About 34.4% of the sexually active participants never used condoms in the past 6 months, and current condom use was associated with egalitarian gender attitudes, positive feelings about condom use, and concerns about contacting HIV/AIDS from their husbands. Among all participants, 32.5% reported that they would not use condoms in their future sexual encounters. Future condom use was related to shorter duration of marriage, accurate HIV/AIDS knowledge, egalitarian gender attitudes, current condom use, and positive feelings about condom use. Results from the logistic regression analyses showed that egalitarian gender attitudes toward sexuality and positive feelings about condom use were the most salient predictors for current and future condom use.

Management of HIV-infected children in the home and institutional settings. Care of children and infections control in schools, day care, hospital settings, home, foster care, and adoption

The likelihood of high-risk pediatric exposure to HIV infection, other than perinatal exposure, has been shown to be low in most cases, and HIV PEP should be considered on a case-by-case basis. Generic considerations in the management of children who have become HIV infected emphasizes the principles of inclusion, maintaining confidentiality of a child's HIV status, and notifying those who need to know about the HIV status to care properly for the child or adolescent. Although appropriate infection-control precautions are applicable for all children and for many pathogens, children especially HIV-infected children, exposed to such pathogens, must be managed in a timely fashion. In many cases, recommendations that are applicable in one setting are applicable in others. Some exceptions apply, including infection-control precautions in hospitals versus other settings. A few additional considerations have been made for special settings and activities, including adoption, foster care, athletics, summer camp, and other recreational activities.

Adherence to colposcopy among women with HIV infection

In the general population, nonadherence to the recommendation to have colposcopy in women with abnormal cytologic smears is estimated at 30% to 80%, but studies have failed to identify consistent risk factors for nonadherence. The purpose of this analysis is to assess adherence to colposcopy in a subset of participants in the Women's Interagency HIV Study (WIHS), an ongoing multisite longitudinal study of HIV infection in women in the United States and determine factors associated with nonadherence. Identification of such predictors would be useful in designing strategies to improve adherence in this group.

METHODS

Adherence to colposcopy was examined in a cohort of 462 women with, or at risk for, HIV infection with abnormal cervical cytology on entry into WIHS. Adherence was defined as having colposcopy done within 6 months of an abnormal cytology result.

RESULTS

Overall adherence to colposcopy was 65% (302 of 462). A multivariate logistic regression model revealed that the odds of adherence were significantly lower for the women who were HIV-infected (p = .011), current crack/cocaine users (p = .040), ever too ill to get medical care (p = .033), not recruited by WIHS study staff (p = .004), and less concerned about the care of their children (p = .037). Among HIV-seropositive women, low CD4 counts, high viral loads, and presence of AIDS-defining illness were not predictive of nonadherence.

DISCUSSION

Adherence to colposcopy among WIHS participants was at the upper limit of the reported range in the United States. Chemical dependency and domestic violence may negatively impact on colposcopy adherence whereas supportive study personnel, having health insurance, and concerns about raising one's children appear to be motivators for adherence to colposcopy in this study. HIV infection was a risk factor for nonadherence, but markers of advanced disease were not predictive of nonadherence.

Service needs and networks of rural women with HIV/AIDS

Despite the fact that one of every 16 women with AIDS in the United States lives in a rural area, little is known about their demographic and epidemiologic characteristics, service needs, social support networks, or service utilization patterns. This article reports key findings from case studies of services to rural women with HIV/AIDS in southwest Georgia, northwest Mississippi, southeastern South Carolina, south Texas, and south-central Washington. Despite the growing numbers of HIV-positive women in these areas, many primary care physicians lack training in the diagnosis and treatment of HIV infection in women, and multidisciplinary protocols for the "shared care" of HIV-positive pregnant women are still being developed. Concerns about confidentiality and the lack of health insurance and transportation pose major access barriers. The findings suggest a need for new kinds of rural initiatives that embed HIV prevention and care into broader programs of educational and economic development.

HIV disease and women

Women with HIV disease are at risk for the same complications as men as their disease progresses. Women, however require some special considerations. This article will elucidate the epidemiology, disease transmission, gynecologic complications, pregnancy, and evaluation of the HIV infected women.

HIV counseling and testing of pregnant women and women of childbearing age by primary care providers: self-reported beliefs and practices

This study describes primary care providers' beliefs and self-reported practices regarding HIV counseling and testing of pregnant women and women of childbearing age. The Centers for Disease Control and Prevention (CDC) recommends that providers counsel and encourage all pregnant women and women of childbearing age to be voluntarily tested, and California requires providers to offer voluntary testing to all pregnant women. We randomly sampled 180 primary care providers in 1995 from the nine-county San Francisco Bay area using a self-administered, mailed survey (response rate = 73%, N = 121). Eighty-six percent of primary care providers (obstetricians/gynecologists, internists, family practitioners, or general practitioners) support voluntary testing, 61% support routine testing without explicit consent, and 55% support mandatory testing. Although 90% of providers are very likely to encourage pregnant women with risk factors to be tested, only 34% are very likely to encourage pregnant women without risk factors to be tested and only 9% are very likely to encourage women of childbearing age without risk factors to be tested. Few providers state that they support policies targeting testing to women with risk factors, yet in practice, providers are much more likely to encourage testing for women with risk factors than those without risk factors. We conclude that providers may be missing opportunities to encourage women to be tested, and women may not be receiving adequate information to make an informed testing decision. Future research is needed to determine the viability of voluntary testing and how to remove barriers to its implementation.
