RESUMO
From September 1988 to August 1989, in a university hospital in Newark, NJ, 3529 serum and plasma specimens from patients with admitting conditions presumably not associated with human immunodeficiency virus (HIV) infection (Centers for Disease Control, Atlanta, Ga, Sentinel Hospital Surveillance System criteria) were tested anonymously for the presence of type 1 HIV (HIV-1) antibody. Of these specimens, 269 (7.6%) were confirmed HIV-1 seropositive. Overall, 10.3% of male patients and 4.8% of female patients were seropositive. Persons 25 to 44 years old had the highest HIV-1 seroprevalence- 20.9% for male and 7.5% for female patients. Based on this anonymous testing, the number of HIV-infected hospitalized patients discharged in 1988 was estimated. Data on hospital-confirmed HIV-infected patients tested on the basis of clinical suspicion suggest that only 40% of HIV-infected patients were actually tested for HIV-1 infection as part of their medical care in this hospital. These data demonstrate a high prevalence of HIV infection in this patient population and suggest that hospitals serving populations with a high HIV seroprevalence offer routine screening for HIV infection as part of good medical care.

OBJECTIVES: Substantial biologic and epidemiologic data indicate the importance of syphilis as a potential cofactor for sexual transmission of HIV infection, but few detailed data exist on the geographic covariation of these two important sexually transmitted infections. DESIGN: HIV prevalence in childbearing women and primary and secondary (P&S) syphilis data from 29 states were examined to explore the importance of the epidemiology of syphilis as a factor in facilitating HIV transmission. METHOD: The spatial relationship between P&S syphilis and HIV infection in the health districts of 29 states was analyzed and adjusted for demographic and socioeconomic factors such as racial composition, income, housing, education levels, and access to medical services using the 1990 US census, and geographic location. RESULTS: In 29 states and the District of Colombia, 448 health districts, representing more than 75% of the US population, reported HIV prevalence rates for mothers' district of residence. The HIV seroprevalence ranged from 0 to 1258/10 000 in these health districts. The incidence of P&S syphilis from 1984-1994 in these districts ranged from 0 to 87/100 000. The P&S syphilis incidence was positively associated with the prevalence of HIV infection among childbearing women (P < 0.0001). CONCLUSIONS: Syphilis that persists in communities in the United States appears to represent a 'sentinel public health event' reflecting risk for sexual HIV transmission. These findings, along with other biologic and epidemiologic information, reinforce the importance of syphilis as an indicator for targeting HIV prevention efforts generally, as well as syphilis control as a specific HIV-prevention strategy.

OBJECTIVE: To determine the impact of HIV counseling and testing among child-bearing women. STUDY SETTING: Mama Yemo Hospital in Kinshasa, Zaïre. PARTICIPANTS AND INTERVENTIONS: After informed consent, 187 HIV-seropositive and 177 HIV-seronegative child-bearing women received pre- and post-test counseling for HIV infection. MAIN OUTCOME MEASURES: Participant knowledge of HIV/AIDS and plans for notifying partners of serologic status and contraceptive use at the time of counseling, and actual partner involvement and contraception use 12 months later. RESULTS: During pre-test counseling, participant knowledge of HIV infection was high, although 30% of women were unaware of perinatal HIV transmission, and 50% did not know that HIV infection could be asymptomatic. At post-test counseling, 70% of mothers (47% of HIV-seropositive, 94% of HIV-seronegative) intended to notify their partners and have joint counseling and testing, although after 12 months, only 2.2% of all women and 7.9% of those who desired assistance to notify their partner returned with their partners for joint counseling and testing. Similarly, 86% planned to use birth control (61% condoms), with HIV-seropositive women more likely to prefer condoms than HIV-seronegative women (71 versus 53%; P < 0.001). After 12-months, however, only 20% of HIV-seropositive women reported condom use, and the frequency of pregnancy in both groups was approximately equal. CONCLUSIONS: HIV counseling and testing led to higher rates of contraceptive and condom use, although the actual level was lower than the intended use. To further reduce the risk of heterosexual and perinatal HIV transmission in families with an HIV-infected woman, counseling should also include their male partners.

OBJECTIVE: A60 is a high molecular weight mycobacterial antigen complex. The detection of immunoglobulin (Ig) G antibodies to A60 has been advocated as a reasonably sensitive and specific test for active tuberculosis (TB). We aimed to compare the sensitivity of this test among HIV-seropositive and HIV-seronegative patients with pulmonary TB. METHODS: The presence and concentration of anti-A60 IgG antibodies was assessed by enzyme-linked immunosorbent assay in 208 HIV-seropositive and 91 HIV-seronegative Zaïrian patients with smear-positive pulmonary TB. The relationship between anti-A60 IgG levels and HIV serostatus, CD4+ lymphocyte counts, presence of clinical AIDS, and tuberculin skin test results was verified. RESULTS: Only 36.5% of the HIV-seropositive, compared with 69.2% of the HIV-seronegative patients had a positive anti-A60 IgG test (P < 0.00001). Among HIV-seropositive patients, anti-A60 IgG levels did not differ according to CD4+ lymphocyte counts, presence of clinical AIDS, or tuberculin skin test results. CONCLUSIONS: Among patients with pulmonary TB, the sensitivity of testing for anti-A60 IgG was much lower among HIV-seropositive than among HIV-seronegative patients, even from the early stages of HIV-related immunodeficiency. This limits the utility of anti-A60 IgG-antibody testing in the diagnosis of TB among HIV-infected patients.

OBJECTIVE: To describe the dynamics of the HIV-1 epidemic in childbearing women in Kinshasa, Zaïre, by estimating incidence from serial seroprevalence studies. METHODS: In 1986 and 1989, 5937 and 4623 pregnant women, respectively, were screened for HIV-1 in Kinshasa. We estimated age-specific incidence from two seroprevalence surveys by using a birth-year cohort analysis and adjusting for differences in mortality and fertility between HIV-1-infected and uninfected women. Mortality and fertility data were measured in a cohort of women recruited from the survey in 1986 and followed until 1989. RESULTS: While the overall HIV-1 seroprevalence changed little (5.8% in 1986 and 6.5% in 1989; P = 0.17), the prevalence increased in birth-year cohorts of women under 25 years of age in 1989 from 3.2 to 6.2% (P < 0.001), but decreased for women above 25 years of age from 6.9 to 6.7% (P = 0.7). In addition, new HIV infections between 1986 and 1989 were balanced by a higher mortality and lower fertility observed in HIV-infected women. After adjusting for these effects, we estimated an overall 3-year cumulative HIV-1 incidence of 2.8 per 100 uninfected women [95% confidence interval (CI), 1.4-4.2]. The highest incidence, 5.7 per 100 (95% CI, 3.5-8.0), was in women aged 20-24 years in 1989. CONCLUSION: Despite an overall relatively stable HIV-1 prevalence in childbearing women in Kinshasa between 1986 and 1989, approximately 40% of all HIV-1 infections detected in the 1989 survey occurred between 1986 and 1989, and 60% occurred in women under 25 years of age in 1989.

OBJECTIVES: To describe trends in prevalence of HIV-1 infection among women giving birth at Chiang Rai Hospital (CRH) and to assess risk factors associated with HIV infection in this population. DESIGN: Analysis of hospital registry data for all deliveries at CRH from 1990 to mid-1997. METHODS: From 1990 to mid-1997, women giving birth at CRH were tested for HIV-1 infection using enzyme immunoassay (EIA); positive sera were confirmed using a different manufacturer's EIA. Demographic and clinical data were abstracted from delivery-ward log books. RESULTS: Data from 40723 deliveries indicated that overall HIV-1 seroprevalence increased sharply, from 1.3% in 1990 to a peak of 6.4% in 1994, and then declined to 4.6% in the first 6 months of 1997. Prevalence was highest, at 7.0%, among young (age < or = 24 years) primigravidas, compared with 2.4% among older (age > or = 25 years) multigravidas. When we controlled for age, prevalence declined 40% from 1994 to 1997 among young primigravidas (95% confidence interval for percentage reduction, 16-57). Amongst older multigravid women, prevalence was consistently lower but increased steadily from 2.7% in 1994 to 3.4% in 1997. CONCLUSIONS: A rapid rise in HIV prevalence in childbearing women was followed by a sharp decline among young primigravidas. In each year, the prevalence was highest among young primigravidas. They may be the best subgroup of pregnant women for monitoring HIV epidemic trends, but they also represent a challenging prevention priority that will require its own targeted interventions.

OBJECTIVE: Policresulen vaginal suppositories are a condensation product of metacresolsulfonic acid and formaldehyde. We investigated their use by female commercial sex workers (CSW) and whether such use could facilitate HIV transmission. METHODS: We interviewed female CSW in Thailand about use of the product, and we directly observed the effects of self-administration of a single suppository by each of six women. RESULTS: Of 200 CSW interviewed, 32% had used policresulen vaginal suppositories in the preceding year and 46% had used them at some time. Many used them for reasons not listed on the package insert, such as improving their male partners' sexual pleasure, and most did not abstain from vaginal sex following use. Among 36 brothel-based and 67 non-brothel-based CSW with known HIV infection, the use of the product was not associated with HIV-1 infection (adjusted relative risk 1.0, 95% confidence interval, 0.5-2.0). Exfoliation of the vaginal and cervical mucosa was observed in all six CSW 1 day after product use, and, although it could have been the result of repeated examinations, an increase in genital HIV-1 RNA shedding was also detected in all three HIV-seropositive women. CONCLUSION: Although there was no epidemiological association with HIV infection, policresulen vaginal suppository use did disrupt the genital mucosa and therefore may have the potential to facilitate HIV transmission. Drug licensing authorities may wish to reassess the safety of this product. If the product continues to be distributed, steps should be taken to limit its use to the specific conditions for which it is indicated and to ensure that women abstain from vaginal sex following its use.

OBJECTIVES: To determine the incidence of HIV-1 infection, temporal trends in incidence, and risk factors for seroconversion in a cohort of female commercial sex workers (CSW) in upper northern Thailand, the region of Thailand with the highest rates of HIV-1 infection. METHODS: CSW were enrolled from 1991 through 1994 and evaluated prospectively with interviews, physical examination, testing for sexually transmitted diseases (STD), and serologic testing for HIV-1 infection. RESULTS: The incidence of HIV-1 seroconversion in the first year of follow-up was 20.3 per 100 person-years among 126 brothel-based CSW and 0.7 per 100 person-years among 159 other CSW who worked in other venues such as bars or massage parlors. Incidence remained elevated among brothel-based CSW who were enrolled later in the study compared with those who enrolled earlier. Through 1996, 30 women seroconverted. In a multivariable proportional hazards model, seroconversion was significantly associated (P < 0.05) with brothel-based sex work (adjusted risk ratio, 7.3) and Chlamydia trachomatis cervical infection (adjusted risk ratio, 3.3). CONCLUSION: Despite national HIV control efforts and declining rates of infection among young men in Thailand, brothel-based CSW may continue to be at high risk for HIV-1 infection. Additional efforts are needed to provide alternative economic choices for young women, to ensure universal condom use during commercial sex, and to develop new prevention technologies.

Maternal antibodies against the V3 loop principal neutralizing domain (PND) have been reported to protect against perinatal HIV-1 transmission. To study this association in an African city with a long-standing HIV epidemic and no established "consensus sequence" for the V3 loop region of gp120, we determined the DNA sequence for the V3 region of HIV-1 from 13 HIV-1-infected residents of Kinshasa, Zaire, and developed peptide enzyme immunoassays (EIAs) reflecting the V3 loop PND for those HIV-1 strains. Using the most broadly reactive locally derived V3 loop peptide in a limited-antigen EIA, there was no significant difference in the perinatal HIV-1 transmission risk between 64 women with anti-V3 loop antibody (transmission risk, 30%) and 104 women without anti-V3 loop antibody (transmission risk, 25%; p = 0.5); this finding was unchanged after we controlled for maternal AIDS and low birth weight. Although we used assays for V3 loop antibody based on local HIV-1 strains and evaluated a large number of mother-child pairs, we found no evidence that maternal anti-V3 loop PND antibody protects against perinatal HIV-1 transmission.

BACKGROUND: Most HIV-infection in children occurs in sub-Saharan Africa where antiretroviral therapy is seldom available. This study compares the growth progression and retardation of HIV-infected and uninfected children in the Democratic Republic of Congo (formerly Zaire). It estimates the risk for child growth retardation according to child and maternal immunological factors, severity of maternal and child illness, and maternal socioeconomic and marital status. METHODS: In a prospective cohort study of 258 children born to HIV seropositive mothers and 256 children of seronegative mothers in Kinshasa, Congo, the growth in length, weight, and weight-for-length of infected children (n = 68), uninfected children born to seropositive mothers (n = 190), and uninfected children born to uninfected mothers (n = 256) was compared. Serological, anthropometric and other clinical measures were collected monthly from 3-12 months and bi-monthly during the second year of life. Polymerase chain reaction for HIV was performed on bloods drawn at 2 days and 3 months post partum. Length-for-age, weight-for-age, and weight-for-length mean z-scores against National Center for Health Statistics (NCHS) reference data were calculated, and Cox proportional hazards models were used to estimate the risk of falling below -2.00 z-scores as a function of child and maternal immunological, clinical and sociodemographic variables. RESULTS: There was no difference in mean length-for-age at birth between HIV-infected (Group 1) children, uninfected children of infected mothers (Group 2) or Control children, but by 3 months old, HIV-infected children were shorter than both Group 2 and Controls. In weight-for-age and weight-for-length, Group 1 infants were lighter and more wasted at birth and onwards. Group 2 newborns were lighter than Controls at birth, but by three months they had caught up to Controls in both length and weight and remained the same as Controls thereafter. The odds of falling below -2.00 z-scores by 20 months for length, weight, and weight-for-length for HIV-infected children compared to uninfected children were 2.10, 2.84, and 2.56 respectively. Both HIV-infection and associated illnesses were factors associated with child stunting, underweight and wasting. The mother's age, socioeconomic status, presence of father, stage of illness and immune status had no detectable effect on the child's growth in the first two years of life. CONCLUSION: The HIV-infected children in Congo with no access to antiretroviral therapy were stunted, underweight, and wasted compared to same age uninfected children. Both HIV infection and HIV-associated signs and symptoms, not maternal immunological or socioeconomic circumstances, placed children at risk for growth retardation.

PURPOSE: To evaluate results of screening for syphilis, gonorrhea, and chlamydia among youth in a federally funded job training program. METHODS: Data were evaluated from medical records of 12,881 randomly selected students in 54 U.S. job training centers during 1996. The intake medical evaluation includes serologic testing for syphilis. The policy was for females to receive a pelvic examination with gonorrhea and chlamydia testing and for males to be first screened with a urine leukocyte esterase (LE) assay, with follow-up gonorrhea and chlamydia testing for those with positive LE results. RESULTS: Adjusting for our sampling strategy, among females, an estimated 9.2% had a positive chlamydia test, 2.7% a positive gonorrhea test, and 0.4% had a positive syphilis test. Gonorrhea and chlamydia rates among females were highest in African-American followed by Native American students. Chlamydia infection was most common in younger women < or = 17 years of age. An estimated 0.1% of males had a positive syphilis test, and 4.8% of males a positive urine LE test. Of 103 LE-positive males tested for gonorrhea and chlamydia, only 27 (26%) had a positive test for one of these STDs. CONCLUSIONS: Our study supports routine screening of adolescents for gonorrhea and chlamydia, including those youth from socioeconomically disadvantaged backgrounds. Because individuals from such backgrounds may not regularly interact with traditional clinical health care systems, screening and treatment should be offered in alternative settings, such as the job training program described in this study.

We conducted a sexually transmitted disease (STD) prevalence survey of 1867 female sex workers in Surabaya, Indonesia, some of whom reported participation in a routine penicillin prophylaxis programme. In Surabaya, 34% of female sex workers had received a prophylactic penicillin injection programme from the government within 28 days. Sex workers who had received routine prophylaxis injection were more likely to be less educated, to work in brothel complexes, and to have more customers per week than other sex workers. The prevalence rates of syphilis, gonorrhoea, chlamydia, and trichomoniasis were higher among sex workers who received the routine penicillin treatment than among those who had not received antibiotic treatment in the last 28 days. However, after adjustment for age, education, fee per sex act, number of customers, and condom use in the previous 7 days, only trichomoniasis was still significantly different (adjusted odds ratio of 3.2). High-risk women were more likely to participate in the routine penicillin prophylaxis programme. The lack of a demonstrable individual-level protection from this prophylaxis treatment programme in this cross-sectional study appears due to differential uptake of penicillin prophylaxis by women at higher presumptive risk for STD. Randomized clinical trials and mathematical modelling, together with observational data such as presented here, all can contribute to optimal understanding of a complex intervention like mass chemoprophylaxis for STD among female sex workers.
PIP: In Surabaya, Indonesia, routine prophylaxis injection with long-acting penicillin to prevent syphilis has been conducted among female prostitutes since 1957, with the goal of severing the syphilis transmission chain by maintaining a treponemicidal level of penicillin of greater than 0.03 mg/ml of blood in the target population. The program currently provides an intramuscular injection of 1.2 million units of benzathine penicillin once every 2 weeks. Based upon sexually transmitted disease (STD) survey data for 1867 female prostitutes in the city, findings are presented from a study comparing the risk profiles of women who participate in the prophylaxis program with women who do not. 635 (34%) of the prostitutes reported having received a prophylactic penicillin injection from the program within the 28 days preceding the survey. Women who had received an injection were more likely to be less educated, to work in brothel complexes, and to have more customers per week than the other prostitutes. Prevalence rates of syphilis, gonorrhea, chlamydia, and trichomoniasis were higher among prostitutes who received the routine penicillin treatment than among those who had not received antibiotic treatment in the past 28 days. However, after adjusting for age, education, fee per sex act, number of customers, and condom use during the preceding 7 days, only trichomoniasis remained significantly different. High-risk women were more likely to participate in the routine penicillin prophylaxis program. The lack of any demonstrable individual-level protection from this prophylaxis treatment program seems due to the differential uptake of penicillin prophylaxis by women at higher presumptive risk for STD.

The U.S. sentinel hospital surveillance system for human immunodeficiency virus (HIV) infection includes approximately 40 short-stay hospitals located in 31 metropolitan areas in the United States and Puerto Rico. Several hospitals began testing in late 1986, and additional sentinel hospitals have since been recruited. At each sentinel hospital, anonymous, unlinked testing for antibody to HIV is conducted monthly on 300 blood specimens, selected systematically and stratified by age of the patient. Specimens are excluded from patients whose reason for hospital visit on that occasion was for a medical condition associated with HIV infection or with risk factors for HIV infection, in order to limit the expected overrepresentation of HIV-infected persons among hospital patients compared with the general catchment population of the hospital. The incidence of acquired immunodeficiency syndrome (AIDS) in metropolitan areas with sentinel hospitals has been approximately twice the incidence of AIDS in the entire United States. However, while absolute levels of HIV seroprevalence should therefore be interpreted with caution, trends in the age-, sex-, and race-specific HIV seroprevalence at sentinel hospitals likely reflect trends in the communities served by the hospitals. Although concentrated in areas disproportionately affected by AIDS, sentinel hospitals will contribute seroprevalence data over time that reflect the impact of HIV infection across all age and behavioral risk groups. Sentinel hospitals will also constitute a key surveillance system to help integrate the age group-specific and risk group-specific findings from other activities in the CDC family of seroprevalence surveys.

We emphasize again that the prevalence of maternal infections may vary in different populations, and others might arrive at different estimates about the percentage of infants colonized and, concerning those infants colonized, about the percentage with adverse outcomes. Additionally, many women are colonized or infected simultaneously with several of the organisms discussed in this review, and this may result in different projections of morbidity and mortality rates than those presented here. We realize also that new information is generated continually describing the relationship between various maternal colonizations and preterm birth, and that screening and treatment protocols for several diseases may reduce the prevalence of adverse outcomes reported here. Therefore, we emphasize that the prevalences of various adverse pregnancy outcomes, as presented in this article, are only approximations and may change as new information becomes available. Nevertheless, we believe it is reasonable to estimate the relative effect of various maternal sexually transmitted diseases on adverse pregnancy outcome as we have done in this article. By comparing the effect of direct transmission of sexually transmitted organisms on adverse outcomes with the effect on overall outcome through an increase in the rate of preterm births, we should be able to use this type of analysis to establish some basis for allocation of resources to future research as well as intervention programs aimed at reducing sexually transmitted disease-related adverse outcomes of pregnancy. Finally, the appreciation of the effect of bacterial vaginosis on outcomes of pregnancy associated with preterm birth gives bacterial vaginosis a greater public health importance than has been attributed to it in the past as the subject of sexually transmitted disease research and prevention.

Reconfiguring and refocusing syphilis control and prevention programs in the United States is required by the changing epidemiology and sociology of syphilis as well as by the importance and magnitude of human immunodeficiency virus (HIV) prevention efforts. An updated strategic approach to syphilis prevention might involve three categories, or tiers, of prevention activities. Tier 1 activities involve the basic elements or tools of prevention programs, such as screening, treatment, partner notification, or behavior change counseling. Tier 2, or prevention effectiveness activities, represent ways to select among the basic prevention elements and to specify how they should be applied in particular epidemiologic situations to yield the greatest impact on disease transmission and persistence from available resources. Tier 3 involves strategic linkages to and alignment with other broad public health programs and initiatives to help accomplish the substantive work of syphilis control and to promote sustained advocacy and public support for syphilis prevention efforts. Although efforts within and across these tiers of syphilis prevention activities should and do reinforce each other, they also compete for resources: Tier 2 activities have been particularly in need of enhancement for many years. Tier 3 activities are especially important in the mid-1990s because, after the major epidemic of the late 1980s, syphilis rates are on the decline, making it urgent but difficult to sustain prevention efforts.

BACKGROUND: Syphilis rates began to decline in 1991 and have decreased every year since. In 1998, 6,993 cases of primary and secondary syphilis were reported in the United States, for a national incidence of 2.6 cases per 100,000 population. Although syphilis rates are at an historic low, focal outbreaks still occur. On October 7, 1999, the Division of Sexually Transmitted Disease Prevention of the Centers for Disease Control and Prevention, in collaboration with federal and community partners, presented the National Plan for Elimination of Syphilis from the United States. One of the five key strategies of the plan is rapid outbreak response. METHODS: Methods for outbreak assessment and response were reviewed in the literature, synthesized, and adapted for use in syphilis outbreaks. RESULTS: Key elements of outbreak assessment and response are detection, surveillance data review, hypothesis generation, intervention development, and the evaluation of clinical, public health, and laboratory services. CONCLUSIONS: Outbreak response necessitates community participation and a coordinated interdisciplinary effort to determine social and behavioral contributors to the outbreak and to develop targeted interventions.

BACKGROUND: Sexually transmitted diseases (STDs) have become an important medical problem in prisons. GOAL: To determine the prevalence of and risk factors for STDs among female inmates in a Brazilian prison. STUDY DESIGN: All female prisoners at the Espírito Santo State Prison were offered enrollment in this cross-sectional study. An interview exploring demographics, criminal charges, and risk behavior was conducted. Blood and genital specimens were collected for STD testing. RESULTS: Of 122 eligible women, 121 (99%) agreed to participate. Prevalence rates were: HIV 9.9%, human T-cell lymphotrophic virus type I 4.1%, hepatitis B virus 7.4%, hepatitis C virus 19%, syphilis 16%, gonorrhea 7.6%, chlamydial infection 11%, human papillomavirus-related cytologic changes 9.3%, trichomoniasis 30%, and bacterial vaginosis 15%. Previous or current drug abuse (54%), injection drug use (11%), and blood transfusion (16%) were associated with at least one STD. Condom use was infrequent. CONCLUSION: The prevalence of STDs and of behaviors leading to ongoing transmission are high among female inmates in Vitória, Brazil, and demonstrate the potential importance of prevention activities targeting this population.
