Prenatal HIV Testing and the Impact of State HIV Testing Laws, 2004 to 2011

Third-trimester repeat HIV testing: it is time we make it universal

Since the 1990s, perinatal transmission of HIV has decreased substantially, largely as a result of improved detection secondary to routine HIV screening in pregnancy and the use of antiretroviral therapy. However, despite reductions in HIV transmission, elimination of perinatal transmission, defined as an incidence of perinatal HIV infection of <1 per 100,000 live births and a transmission rate of <1%, remains elusive. An estimated 80% of perinatal transmissions occur after 36 weeks' gestation, which highlights the importance of diagnosis and treatment of maternal HIV infection before the highest-risk period for perinatal transmission. With timely identification of seroconversion, intrapartum and neonatal interventions can lower the risk of perinatal transmission from 25% to 10%, substantially reducing perinatal transmission events. The American College of Obstetricians and Gynecologists and the Centers for Disease Control and Prevention recommend that routine HIV testing be performed in all pregnancies, as early in the prenatal course as possible. Third-trimester repeat testing is only recommended for individuals known to be at high risk of acquiring HIV (ie, those who are incarcerated; who reside in jurisdictions with elevated HIV incidence; who are receiving care in facilities that have an HIV incidence in pregnant women > 1 per 1000 per year; or have signs or symptoms of acute HIV). However, among reproductive-age women, heterosexual intercourse is the most common mode of HIV transmission, and the risk of HIV seroconversion is greater during pregnancy than outside of pregnancy. Furthermore, state statutes for HIV testing in pregnancy are largely lacking. In this clinical opinion, we reviewed the evidence in support of universal third-trimester repeat HIV testing in pregnancy using a successful state-mandated testing program in Illinois. In addition, we provided clinical recommendations to further reduce missed perinatal transmission cases by implementing universal third-trimester repeat testing, obtaining hospital buy-in, monitoring testing adherence, bridging communications across multidisciplinary teams, and engaging clinicians in advocacy work.

Equitable Timing of HIV Diagnosis Prior to Pregnancy: A Canadian Perspective

Initiating antiretrovirals prior to conception leads to a negligible risk of perinatal transmission. This study aimed to determine the timing of HIV diagnosis among pregnant women with HIV in Ontario. A retrospective population-level cohort study using linked health administrative databases was conducted to establish maternal HIV status and timing of HIV diagnosis of all women living with HIV who gave birth in 2006-2018. The majority of the 1012 women living with HIV who gave birth in Ontario were diagnosed prior to pregnancy (87.9%); however, many were not (12.1%). Among those diagnosed during pregnancy, only 23% were diagnosed in the first trimester. While HIV screening tests are being well directed towards young women, several women still enter pregnancy undiagnosed and are not diagnosed early. This calls for a continuous effort to promote universal pre-conception screening and to use HIV point-of-care testing for at-risk pregnant women and those presenting late to prenatal care.

Provider-Initiated HIV Testing in Puerto Rico from Data of the National HIV Behavioral Surveillance-Heterosexual Cycle (NHBS-HET) 2016: National Cross-Sectional Survey (Preprint)

Background

According to the Centers for Disease Control and Prevention and World Health Organization guidelines, all individuals aged 13-64 years should get screened for HIV infection as part of their routine medical examinations. Individuals at high risk should get tested annually.

Objective

This study aimed to identify the sociodemographic, health care, and sexual behavioral characteristics of provider-initiated HIV testing using data from the Puerto Rico National HIV Behavioral Surveillance 2016 cycle, directed toward heterosexual individuals at increased risk of HIV infection.

Methods

A sample of 358 eligible participants were recruited through respondent-driven sampling, where sociodemographic characteristics, health care use, and HIV test referral were used to assess a description of the study sample. Pearson chi-square and Fisher tests were used to evaluate proportional differences. Multivariate logistic regression models were performed to determine the association between independent variables and HIV test referral. Adjusted prevalence ratios by sex and age with their 95% CIs were determined using a statistical significance level of .05.

Results

Despite 67.9% (243/358) of participants showing high-risk sexual behavioral practices and 67.4% (236/350) reporting a low perceived risk of HIV infection among those who visited a health care provider within the last 12 months, 80.7% (289/358) of the study sample did not receive an HIV test referral at a recent medical visit. Multivariate analysis showed that the estimated prevalence of the participants who received an HIV test referral among those who reported being engaged in high-risk sexual behaviors was 41% (adjusted prevalence ratio .59, 95% CI .39-.91; P=.02) lower than the estimated prevalence among those who did not engage in high-risk sexual behavior.

Conclusions

This sample of Puerto Rican adults reported a significantly lower prevalence of receiving an HIV test referral among heterosexual individuals at increased risk of HIV infection who engaged in high-risk behaviors. This study further emphasizes the need for health care providers to follow recommended guidelines for HIV test referrals in health care settings. Promotion practices in the future should include enhancing referral and access to HIV tests and implementing preventive measures to counteract the HIV epidemic in Puerto Rico.

HIV testing among pregnant women with prenatal care in the United States: An analysis of the 2011-2017 National Survey of Family Growth

Although there has been significant progress in reducing perinatal human immunodeficiency virus (HIV) transmission, the United States is yet to meet the proposed elimination goal of less than one infection per 100,000 live births. Failure to screen all pregnant women for HIV as recommended by the Centers for Disease Control and Prevention can result in missed opportunities for preventing vertical transmission of HIV with antiretroviral drugs. Using the 2011-2017 National Survey of Family Growth, this study examined HIV testing among pregnant women during prenatal care. We estimated the weighted proportion of self-reported HIV testing among women whose last pregnancy ended within 12 months prior to the interview. Logistic regression models were used to determine the factors associated with HIV testing. Of the 1566 women included in the study, 76.4% (95% confidence intervals [CI] = 72.8-80.0) reported receiving an HIV test during prenatal care. In the multivariable regression model, high school diploma (adjusted odds ratio [aOR] = 1.9, 95% CI = 1.1-3.1), two completed pregnancies (aOR = 1.7, 95% CI = 1.1-2.7), health insurance coverage in the last 12 months (aOR = 1.6, 95% CI = 1.0-2.6), Hispanic race/ethnicity (aOR = 2.8, 95% CI = 1.8-4.4), and non-Hispanic black race/ethnicity (aOR = 2.2, 95% CI = 1.3-3.8) were associated with higher odds of reporting being tested for HIV. However, household income of 300% or more of the federal poverty level (aOR = 0.6, 95% CI = 0.3-0.9) and urban residence (aOR = 0.5, 95% CI = 0.3-0.9) were associated with lower odds of reporting HIV testing. These findings suggest that HIV testing among pregnant women during prenatal care is not universal and may affect achieving the goal of elimination of mother-to-child transmission of HIV in the United States.

Epidemiology of Perinatal HIV Transmission in the United States in the Era of Its Elimination

The number of infants born with HIV in the United States has decreased for years, approaching the Centers for Disease Control and Prevention's incidence goal for eliminating perinatal HIV transmission. We reviewed recent literature on perinatal HIV transmission in the United States. Among perinatally HIV-exposed infants (whose mothers have HIV, without regard to infants' HIV diagnosis), prenatal and natal antiretroviral use has increased, maternal HIV infection is more frequently diagnosed before pregnancy and breast-feeding is uncommon. In contrast, mothers of infants with HIV are tested at a lower rate for HIV, receive prenatal care less often, receive antiretrovirals (prenatal and natal) less often and breastfeed more often. The incidence of perinatal HIV remains 5 times as high among black than white infants. The annual number of births to women with HIV was estimated last for 2006 (8700) but has likely decreased. The numbers of women of childbearing age living with HIV and HIV diagnoses have decreased. The estimated time from HIV infection to diagnosis remains long among women and men who acquired HIV heterosexually. It is important to review the epidemiology and to continue monitoring outcomes and other health indicators for reproductive age adults living with HIV and their infants.

Perinatal HIV Service Coordination: Closing Gaps in the HIV Care Continuum for Pregnant Women and Eliminating Perinatal HIV Transmission in the United States

Eliminating perinatal transmission of HIV and improving the care of childbearing women living with HIV in the United States require public health and clinical leadership. The Comprehensive Care Workgroup of the Elimination of Perinatal HIV Transmission Stakeholders Group, sponsored by the Centers for Disease Control and Prevention, developed a concept of perinatal HIV service coordination (PHSC) and identified 6 core functions through (1) semistructured exploratory interviews with contacts in 11 state or city health departments from April 2011 through February 2012, (2) literature review and summary of data on gaps in services and outcomes, and (3) group meetings from August 2010 through June 2017. We discuss leadership strategies for implementing the core functions of PHSC: strategic planning, access to services, real-time case finding, care coordination, comprehensive care, and data and case reviews. PHSC provides a systematic approach to optimize services and close gaps in perinatal HIV prevention and the HIV care continuum for childbearing women that can be individualized for jurisdictions with varying needs.
