HPV vaccination rates continue to climb among young adults in U.S.
Although vaccination rates against the human papillomavirus remain low for young adults across the United States, the number of self-reported HPV vaccinations among women and men aged between 18 and 21 years has markedly increased since 2010, according to new research findings.
The findings were published online April 27, 2021, as a research letter in JAMA.
In 2006, the Food and Drug Administration approved the HPV vaccine for the prevention of cervical cancer and genital warts in female patients. Three years later, the FDA approved the vaccine for the prevention of anogenital cancer and warts in male patients.
The Advisory Committee on Immunization Practices and the Centers for Disease Control and Prevention recommend two doses of the HPV vaccine for children aged 11-12 years. Adolescents and young adults may need three doses over the course of 6 months if they start their vaccine series on or following their 15th birthday.
For persons who have not previously received the HPV vaccine or who did not receive adequate doses, the HPV vaccine is recommended through age 26. Data on the rates of vaccination among young adults between 18 and 21 years of age in the United States are sparse, and it is not known how well vaccination programs are progressing in the country.
In the recently published JAMA research letter, investigators from the University of Michigan, Ann Arbor, examined data for the period 2010-2018 from the cross-sectional National Health Interview Survey. Respondents included in the analysis were aged 18-21 years. They were asked whether they had received the HPV vaccine before age 18 and at what age they had been vaccinated against the virus.
The researchers also assessed whether the respondents had received any HPV vaccine dose between the ages of 18 and 21 years. The findings were limited to self-reported vaccination status.
In total, 6,606 women and 6,038 men were included in the analysis. Approximately 42% of women and 16% of men said they had received at least one HPV vaccine dose at any age. The proportion of female patients who reported receiving an HPV vaccine dose significantly increased from 32% in 2010 to 55% in 2018 (P =.001). Similarly, among men, the percentage significantly increased from 2% in 2010 to 34% in 2018 (P <.001).
Approximately 4% of the female respondents and 3% of the male respondents reported that they had received an HPV vaccine between the ages of 18 and 21 years; 46% of women and 29% of men who received the vaccine between these ages completed the recommended vaccination series.
Findings from the study highlight the continual need for improving vaccination rates among vulnerable populations. Lead study author Michelle Chen, MD, MHS, a professor in the department of otolaryngology–head and neck surgery at the University of Michigan, explained in an interview that there are multiple barriers to HPV vaccination among young adults. “These barriers to vaccination among young adults primarily include cost, lack of knowledge and awareness, missed opportunities for vaccination, rapidly changing guidelines, and initial gender-based guidelines,” said Dr. Chen.
Clinicians play a large role in improving vaccination rates among young adults, who may lack awareness of the overall importance of inoculation against the potentially debilitating and deadly virus. Dr. Chen noted that clinicians can lead the way by increasing gender-inclusive awareness of HPV-associated diseases and HPV vaccination, by performing routine vaccine eligibility assessments for young adults regardless of sex, by developing robust reminder and recall strategies to improve series completion rates, and by offering patients resources regarding assistance programs to address cost barriers for uninsured patients.
“Young adult men are particularly vulnerable [to HPV], because they start to age out of pediatric health practices,” added Dr. Chen. “Thus, a multilevel gender-inclusive approach is needed to target clinicians, patients, parents, and community-based organizations.”
Gypsyamber D’Souza, PhD, professor of epidemiology at Johns Hopkins University, Baltimore, said in an interview that the initial uptake of HPV vaccination was slow in the United States but that progress has been made in recent years among persons in the targeted age range of 11-12 years. “However, catch-up vaccination has lagged behind, and sadly, we’re still seeing low uptake in those older ages that are still eligible and where we know there still is tremendous benefit,” she said.
Dr. D’Souza is a lead investigator in the MOUTH trial, which is currently enrolling patients. That trial will examine potential biomarkers for oropharyngeal cancer risk among people with known risk factors for HPV who came of age prior to the rollout of the vaccine.
She explained that many parents want their children to be vaccinated for HPV after they hear about the vaccine, but because the health care system in the United States is an “opt-in” system, rather than an “opt-out” one, parents need to actively seek out vaccination. Children then move toward adulthood without having received the recommended vaccine course. “There are individuals who did not get vaccinated at the ages of 11 and 12 and then forget to ask about it later, or the provider asks about it and the patients don’t have enough information,” Dr. D’Souza said.
She noted that one reason why HPV vaccination rates remain low among young adults is that the vaccine is not often kept in stock other than in pediatric clinics. “Because vaccines expire and clinics don’t have a lot of people in that age group getting vaccinated, they may not have it regularly in stock, making this one reason it might be hard for someone to get vaccinated.”
The HPV vaccine is not effective for clearing HPV once a patient acquires the infection, she added. “So young adulthood is a critical time where we have individuals who still can benefit from being vaccinated, but if we wait too long, they’ll age out of those ages where we see the highest efficacy.”
Ultimately, said Dr. D’Souza, clinicians need to catch people at multiple time points and work to remove barriers to vaccination, including letting patients know that HPV vaccination is covered by insurance. “There’s a lot of opportunity to prevent future cancers in young adults by having care providers for that age group talk about the vaccine and remember to offer it.”

CDC: STI rates rise for sixth year in a row
Annual cases of sexually transmitted infections in the United States jumped for the sixth year in a row in 2019, according to a new Centers for Disease Control and Prevention report that highlights an increase in congenital syphilis and rising rates of syphilis, chlamydia, and gonorrhea in men, especially men who have sex with men (MSM).
The report says nothing about STI rates during the COVID-19 pandemic, when both casual sex and disease screening and surveillance declined significantly, at least in the early months. But epidemiologist Patricia Kissinger, PhD, MPH, from Tulane University School, New Orleans, said in an interview that the findings reflect how “a confluence of factors” drove up rates before the age of COVID. Those factors include online dating, the opioid epidemic, the decline in condom use in the MSM community as HIV became more preventable, and indifference among policy makers and the community at large.
The CDC report, based on data from local health departments, says there were 129,813 cases of syphilis in 2019, up 74% since 2015. Almost 2,000 cases of congenital syphilis were reported, up 279% since 2015, and 128 infants died.
“There’s no reason for us to have congenital syphilis,” said Dr. Kissinger, who noted that the disease can cause birth defects and meningitis in addition to death. “Women should be screened, and it’s relatively easy to treat via penicillin injections.”
Indeed, medical guidelines suggest that pregnant women be routinely tested for syphilis. But that doesn’t always happen because “it falls through the cracks,” Dr. Kissinger said. Or, she added, women might not be tested enough times during their pregnancies: “You have to screen women in the third trimester. You can’t just do it in the first trimester because people do have sex when they’re pregnant.”
Rising congenital syphilis numbers have convinced at least one health system to take action. As of June 1, the University of California, San Diego, will routinely test pregnant women in the emergency department for syphilis in addition to HIV and hepatitis C, Martin Hoenigl, MD, a UCSF infectious disease specialist, said in an interview.
The CDC report also notes 1.8 million cases of chlamydia in 2019, a jump of 19% in 4 years, and a 56% increase in gonorrhea in that time period, to a total of 616,392 cases.
The report says increasing gonorrhea and chlamydia cases in men, especially MSM, could be caused by increased testing/screening, increased transmission, or both. Although women are generally diagnosed with chlamydia more often than men, the report says, numbers among men grew by 32% from 2015 to 2019. And since 2013, rates of gonorrhea among men have risen at a much faster clip than among women.
MSM accounted for most male cases of primary and secondary syphilis in 2019, although the report said the apparent long-term rise in these cases might be slowing.
Many MSM no longer use condoms because they’re using pre-exposure prophylaxis (PrEP) or have undetectable levels of HIV because of treatment, said Jeffrey Klausner, MD, MPH, an STI specialist at the University of Southern California in Los Angeles, said in an interview.
Many MSM might be getting screened much more often for STIs than in the past because frequent screening is required for those on PrEP. However, Dr. Kissinger said some clinics weren’t able to test at times during the pandemic because of a swab shortage. In addition, patients of all types avoided routine medical care during the pandemic, and some medical professionals in the infectious disease field were redirected to COVID care.
Clinical trials have been investigating a possible preventive STI strategy in MSM who don’t wear condoms – prophylaxis, either before or after exposure, with the antibiotic doxycycline. “That’s a very good solution,” Dr. Klausner said, but he believes bigger challenges remain. According to him, the existence of the report itself – which offers statistics from 2 years ago instead of more relevant recent numbers – is evidence of how the federal government isn’t doing enough to fight STIs. “If we’re taking the STD epidemic seriously, there should be timely and regular reporting.” Dr. Klausner said he likes the idea of monthly reports, as well as more funding for prevention.
Instead, he noted, the federal government cut STI prevention funding by 40% in inflation-adjusted dollars from 2002-2003 to 2018-2019, according to the National Coalition of STD Directors. “Burying your head in the sand and hoping the problem goes away is not an effective strategy,” he said.
It’s not clear whether STI rates are on the decline because of pandemic restrictions and stay-at-home orders. Surveys suggest that a dip in casual sex early in pandemic – when much of society shut down – was only temporary, Dr. Klausner said.
Dr. Kissinger disclosed no relevant financial relationships. Dr. Hoenigl reported receiving research funding via his university from Gilead. Dr. Klausner has recently provided consulting services to Danaher, Cepheid, Roche, GlaxoSmithKline, Talis Bio, SpeeDx, and Visby Medical, all manufacturers of diagnostic assays for STIs.

Antimicrobial, pH-modulating gel shows promise in preventing common STIs
An investigational vaginal gel significantly reduced urogenital chlamydia and gonorrhea in women at high risk for infection, compared with placebo, opening up new possibilities for an on-demand prevention option. Investigators of a randomized trial reported these findings in the American Journal of Obstetrics and Gynecology.
Rates of Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (GC) are on the rise in the United States, despite wide availability of male and female condoms to prevent sexually transmitted infections. This suggests that women need a more discrete method that they can better control. Other vaginal microbicides developed over the last few decades haven’t performed well in protecting against STIs or HIV in clinical trials.
The slightly alkaline nature of human semen has the potential to neutralize vaginal pH after intercourse, creating a more vulnerable environment for STIs. EVO100 is an investigational antimicrobial, bioadhesive vaginal gel that contains L-lactic acid, citric acid, and potassium bitartrate. In preclinical studies, it was highly effective at buffering the alkaline properties of human semen and maintaining vaginal pH levels. Patients generally tolerated it well, aside from some reports of vaginal itching and burning.
In the AMPREVENCE study, a double-blinded, placebo-controlled, randomized, phase 2b/3 trial, Todd Chappell, MD, of Adams Patterson Gynecology & Obstetrics, Memphis, and colleagues tested the efficacy and safety of EVO100 to prevent chlamydia and gonorrhea.
Investigators randomized 1:1,860 healthy, sexually active women to receive either EVO100 (n = 426) or placebo (n = 434). Participants had either been diagnosed or treated for these STIs up to 16 weeks prior to enrollment. Among those enrolled, 335 women in the EVO100 arm and 335 women in the placebo arm completed the study.
From this cohort, 764 women (EVO100: n = 376; placebo: n = 388) reported any use of either product. These women represented the “safety analysis population,” a predefined population for statistical analysis.
Participants averaged nearly 28 years of age, had a median body mass index of 28.9 kg/m2, and represented several racial/ethnic groups: White (54.3% [467/860]), African American (41.6% [358/860]), and non-Hispanic/Latinx ethnicity (67.1% [577/860]).
The women were instructed to apply the drug within 1 hour of initiating sexual intercourse. Investigators scheduled follow-up visits every 4 weeks during the 16-week study period, to obtain repeat CT/GC assessments, review diary entries, and to collect information about adverse effects and use of concomitant medications. During enrollment, participants consented to return to the clinic at each study visit. If a woman missed a visit, the study site would follow-up by telephone after the missed assessment visit.
Participants reported a mean number of 16 coital events (EVO100, 15.7 [13.5]; placebo, 16.3 [15.8]). EVO100 significantly reduced STI incidence for both types of STIs. CT infection rates among EVO100 users was 4.8% (14/289), half of what it was in placebo users (9.7% [28/290]) (P = .0256). The investigational method was even more successful in GC-analysis–eligible women: infection rates averaged 0.7% (2/280), compared with 3.2% (9/277) in the placebo group, a relative risk reduction of 78% (P = .0316).
Examining electronic diary entries of the participants, investigators reported similar adherence rates among the two treatment arms. However, additional sensitivity analyses in CT-eligible and GC-eligible populations on adherence yielded notably different results.
EVO100 users in the CT population who used the product as directed 100% of the time were significantly less likely to become infected, compared with the placebo group (2.3% vs. 16.9%, P = .0012). However, investigators found no significant differences in infection rates among women with poorer adherence rates in the two groups. Comparatively, they found no major differences in GC infection rates between the control and EVO100 groups, regardless of adherence rates, likely because of the small number of GC infections reported. Observed adverse events correlated with the drug’s known safety profile.
Most of the participants said they would likely recommend EVO100 to other women and continue using this preventive treatment.
A small GC subgroup caused by fewer infection cases and reliance on participant self-reporting of coital incidents may have limited the study’s results. “While use of the electronic diaries is helpful for collection of study data, it may encourage compliance and efficacy that may be higher in the ‘real-world’ population outside of the setting of a clinical trial,” noted Dr. Chappell and colleagues.
According to the investigators, this is the first prospective, randomized trial to study the use of an antimicrobial bioadhesive vaginal gel for preventing CT and GC infection. “EVO100 has the potential of fulfilling an unmet need in women’s sexual health as a new on-demand, woman-controlled option that reduces the risk of urogenital CT and GC infections,” the authors concluded.
The Food and Drug Administration has already approved EVO100 as a contraceptive option (Phexxi), Dr. Chappell said in an interview. Next steps are to conduct a phase 3 trial, which is currently underway. “If the findings are positive, we will submit to the FDA for review and approval of EVO100” for preventing these STIs.
These are promising results, Catherine Cansino, MD, MPH, an associate clinical professor with the department of obstetrics and gynecology at the University of California, Davis, said in an interview. It’s always helpful to look at effective treatments, “especially those that aren’t traditional antibiotics in order to decrease the risk of antibiotic resistance,” said Dr. Cansino, who was not part of the study. This is why EVO100 is such an attractive option.
Future studies should look at a broader population, she continued. “The population this study looked at is not the general population – these women had an infection at some point, previously,” which means they are potentially at higher risk for reinfection. “Looking at what their likelihood is of getting infected again, it’s hard to know if this would be the same or different from the general population.” If the drug appears to cause a decrease in new infections, the relative risk reduction is actually greater than what’s reported. If the reinfection rate for this population is lower because people who’ve had infections are practicing safer sex, the relative risk reduction would be lower, explained Dr. Cansino.

An investigational vaginal gel significantly reduced urogenital chlamydia and gonorrhea in women at high risk for infection, compared with placebo, opening up new possibilities for an on-demand prevention option. Investigators of a randomized trial reported these findings in the American Journal of Obstetrics and Gynecology.
Rates of Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (GC) are on the rise in the United States, despite wide availability of male and female condoms to prevent sexually transmitted infections. This suggests that women need a more discrete method that they can better control. Other vaginal microbicides developed over the last few decades haven’t performed well in protecting against STIs or HIV in clinical trials.
The slightly alkaline nature of human semen has the potential to neutralize vaginal pH after intercourse, creating a more vulnerable environment for STIs. EVO100 is an investigational antimicrobial, bioadhesive vaginal gel that contains L-lactic acid, citric acid, and potassium bitartrate. In preclinical studies, it was highly effective at buffering the alkaline properties of human semen and maintaining vaginal pH levels. Patients generally tolerated it well, aside from some reports of vaginal itching and burning.

FROM THE AMERICAN JOURNAL OF OBSTETRICS AND GYNECOLOGY
New NAS report seeks to modernize STI paradigm
Approximately 68 million cases of sexually transmitted infections are reported in the United States each year, yet antiquated approaches to STI prevention, in addition to health care inequities and lack of funding, have substantially prevented providers and officials from curbing the spread. In response to rising case numbers, the National Academies of Sciences, Engineering, and Medicine released a report this week with recommendations to modernize the nation’s STI surveillance and monitoring systems, increase the capabilities of the STI workforce, and address structural barriers to STI prevention and access to care.
Given the rising rates of STIs and the urgent, unmet need for prevention and treatment, the Centers for Disease Control and Prevention’s National Association of County and City Health Officials commissioned the National Academies to develop actionable recommendations to control STIs. The new report marks a long road toward the public’s willingness to discuss STDs, or what a 1997 Institute of Medicine report described as a “hidden epidemic” that had been largely neglected in public discourse.
Jeffrey Crowley, MPH, committee member and an author of the new National Academies report, said in an interview that, despite the increased openness to discuss STIs in today’s society, STD rates since the late 1990s have gotten much worse. Lack of appropriate governmental funding for research and drug development, structural inequities, and persisting stigmatization are key drivers for rising rates, explained Mr. Crowley.
Addressing structural barriers to STI prevention
Playing a prominent role in the National Academies report are issues of structural and institutional barriers to STI prevention and care. In the report, the authors argued that a policy-based approach should seek to promote sexual health and eliminate structural racism and inequities to drive improvements in STI management.
“We think it’s these structural factors that are central to all the inequities that play out,” said Mr. Crowley, “and they either don’t get any attention or, if they do get attention, people don’t really speak concretely enough about how we address them.”
The concrete steps, as outlined in the report, begin with addressing factors that involve the health care industry at large. Automatic STI screening as part of routine visits, alerts in electronic health records that remind clinicians to screen patients, and reminders to test patients can be initial low-cost actions health care systems can take to improve STI testing, particularly in marginalized communities. Mr. Crowley noted that greater evidence is needed to support further steps to address structural factors that contribute to barriers in STI screening and treatment access.
Given the complexities inherent in structural barriers to STI care, the report calls on a whole-government response, in partnership with affected communities, to normalize discussions involving sexual well-being. “We have to ask ourselves how we can build healthier communities and how can we integrate sexual health into that dialogue in a way that improves our response to STI prevention and control,” Mr. Crowley explained.
Harnessing AI and dating apps
The report also addresses the power of artificial intelligence to predict STI rates and to discover trends in risk factors, both of which may improve STI surveillance and assist in the development of tailored interventions. The report calls for policy that will enable companies and the government to capitalize on AI to evaluate large collections of data in EHRs, insurance claims databases, social media, search engines, and even dating apps.
In particular, dating apps could be an avenue through which the public and private sectors could improve STI prevention, diagnosis, and treatment. “People want to focus on this idea of whether these apps increase transmission risk,” said Mr. Crowley. “But we would say that this is asking the wrong question, because these technologies are not going away.” He noted that private and public enterprises could work together to leverage these technologies to increase awareness of prevention and testing.
Unifying the STI/HIV and COVID-19 workforce
The report also recommends that the nation unify the STI/HIV workforce with the COVID-19 workforce. Given the high levels of expertise in these professional working groups, the report suggests unification could potentially address both the current crisis and possible future disease outbreaks. Combining COVID-19 response teams with underresourced STI/HIV programs may also improve the delivery of STI testing, considering that STI testing programs have had to compete for resources during the pandemic.
Addressing stigma
The National Academies report also addresses the ongoing issue of stigma, which results from “blaming” individuals and the choices they make so as to create shame, embarrassment, and discrimination. Because of stigma, sexually active people may be unwilling to seek recommended screening, which can lead to delays in diagnosis and treatment and can increase the risk for negative health outcomes.
“As a nation, we’ve almost focused too intently on individual-level factors in a way that’s driven stigma and really hasn’t been helpful for combating the problem,” said Mr. Crowley. He added that, instead of focusing solely on individual-level choices, the nation should instead work to reframe sexual health as a key aspect of overall physical, mental, and emotional well-being. Doing so could create more opportunities to address structural barriers to STI prevention and ensure that more prevention and screening services are available in stigma-free environments.
“I know what we’re recommending is ambitious, but it’s not too big to be achieved, and we’re not saying tomorrow we’re going to transform the world,” Mr. Crowley concluded. “It’s a puzzle with many pieces, but the long-term impact is really all of these pieces fitting together so that, over time, we can reduce the burden STIs have on the population.”
Implications for real-world change
H. Hunter Handsfield, MD, professor emeritus of medicine for the Center for AIDS and STD at the University of Washington, Seattle, said in an interview that this report essentially is a response to evolving societal changes, new and emerging means of social engagement, and increased focus on racial/ethnic disparities. “These features have all come to the forefront of health care and general policy discussions in recent years,” said Dr. Handsfield, who was not part of the committee that developed the NAS report.
Greater scrutiny on public health infrastructure and its relationship with health disparities in the United States makes the publication of these new recommendations especially appropriate during this era of enhanced focus on social justice. Although the report features the tone and quality needed to bolster bipartisan support, said Dr. Handsfield, it’s hard to predict whether such support will come to fruition in today’s political environment.
In terms of the effects the recommendations may have on STI rates, Dr. Handsfield noted that cherry-picking elements from the report to direct policy may result in its having only a trivial impact. “The report is really an appropriate and necessary response, and almost all the recommendations made can be helpful,” he said, “but for true effectiveness, all the elements need to be implemented to drive policy and funding.”

Unifying the STI/HIV and COVID-19 workforce
The report also recommends that the nation unify the STI/HIV workforce with the COVID-19 workforce. Given the high levels of expertise in these professional working groups, the report suggests unification could potentially address both the current crisis and possible future disease outbreaks. Combining COVID-19 response teams with underresourced STI/HIV programs may also improve the delivery of STI testing, considering that STI testing programs have had to compete for resources during the pandemic.
Addressing stigma
The National Academies report also addresses the ongoing issue of stigma, which results from “blaming” individuals and the choices they make so as to create shame, embarrassment, and discrimination. Because of stigma, sexually active people may be unwilling to seek recommended screening, which can lead to delays in diagnosis and treatment and can increase the risk for negative health outcomes.
“As a nation, we’ve almost focused too intently on individual-level factors in a way that’s driven stigma and really hasn’t been helpful for combating the problem,” said Mr. Crowley. He added that, instead of focusing solely on individual-level choices, the nation should instead work to reframe sexual health as a key aspect of overall physical, mental, and emotional well-being. Doing so could create more opportunities to address structural barriers to STI prevention and ensure that more prevention and screening services are available in stigma-free environments.
“I know what we’re recommending is ambitious, but it’s not too big to be achieved, and we’re not saying tomorrow we’re going to transform the world,” Mr. Crowley concluded. “It’s a puzzle with many pieces, but the long-term impact is really all of these pieces fitting together so that, over time, we can reduce the burden STIs have on the population.”
Implications for real-world change
H. Hunter Handsfield, MD, professor emeritus of medicine for the Center for AIDS and STD at the University of Washington, Seattle, said in an interview that this report essentially is a response to evolving societal changes, new and emerging means of social engagement, and increased focus on racial/ethnic disparities. “These features have all come to the forefront of health care and general policy discussions in recent years,” said Dr. Handsfield, who was not part of the committee that developed the NAS report.
Greater scrutiny on public health infrastructure and its relationship with health disparities in the United States makes the publication of these new recommendations especially appropriate during this era of enhanced focus on social justice. Although the report features the tone and quality needed to bolster bipartisan support, said Dr. Handsfield, it’s hard to predict whether such support will come to fruition in today’s political environment.
In terms of the effects the recommendations may have on STI rates, Dr. Handsfield noted that cherry-picking elements from the report to direct policy may result in its having only a trivial impact. “The report is really an appropriate and necessary response, and almost all the recommendations made can be helpful,” he said, “but for true effectiveness, all the elements need to be implemented to drive policy and funding.”

Zika vaccine candidate shows promise in phase 1 trial
in a phase 1 study.
Although Zika cases have declined in recent years, “geographic expansion of the Aedes aegypti mosquito to areas where population-level immunity is low poses a substantial risk for future epidemics,” wrote Nadine C. Salisch, PhD, of Janssen Vaccines and Prevention, Leiden, the Netherlands, and colleagues in a paper published in Annals of Internal Medicine.
No vaccine against Zika is yet available, although more than 10 candidates have been studied in preclinical trials to date, they said.
The researchers randomized 100 healthy adult volunteers to an experimental Zika vaccine candidate known as Ad26.ZIKV.001 in either one-dose or two-dose regimens of 5x1010 viral particles (low dose) or 1x1011 viral particles (high dose) or placebo. Approximately half (55%) of the participants were women, and 72% were White.
Approximately 80% of patients in both two-dose groups showed antibody responses for a year after vaccination. Geometric mean titers (GMTs) reached peak of 823.4 in the low-dose/low-dose group and 961.5 in the high-dose/high-dose group. At day 365, the GMTs for these groups were 68.7 and 87.0, respectively.
A single high-dose vaccine achieved a similar level of neutralizing antibody titers, but lower peak neutralizing responses than the two-dose strategies, the researchers noted.
Most of the reported adverse events were mild to moderate, and short lived; the most common were injection site pain or tenderness, headache, and fatigue, the researchers said. After the first vaccination, 75% of participants in the low-dose groups, 88% of participants in high-dose groups, and 45% of participants receiving placebo reported local adverse events. In addition, 73%, 83%, and 40% of the participants in the low-dose, high-dose, and placebo groups, respectively, reported systemic adverse events. Reports were similar after the second vaccination. Two serious adverse events not related to vaccination were reported; one case of right lower lobe pneumonia and one case of incomplete spontaneous abortion.
The researchers also explored protective efficacy through a nonlethal mouse challenge model. “Transfer of 6 mg of IgG from Ad26.ZIKV.001 vaccines conferred complete protection from viremia in most recipient animals, with statistically significantly decreased breakthrough rates and cumulative viral loads per group compared with placebo,” they said.
The study findings were limited by the inability to assess safety and immunogenicity in an endemic area, the researchers noted. However, “Ad26.ZIKV.001 induces potent ZIKV-specific neutralizing responses with durability of at least 1 year, which supports further clinical development if an unmet medical need reemerges,” they said. “In addition, these data underscore the performance of the Ad26 vaccine platform, which Janssen is using for different infectious diseases, including COVID-19,” they noted.
Ad26 vector platform shows consistency
“Development of the investigational Janssen Zika vaccine candidate was initiated in 2015, and while the incidence of Zika virus has declined since the 2015-2016 outbreak, spread of the ‘carrier’ Aedes aegypti mosquito to areas where population-level immunity is low poses a substantial risk for future epidemics,” lead author Dr. Salisch said in an interview. For this reason, researchers say the vaccine warrants further development should the need reemerge, she said.
“Our research has found that while a single higher-dose regimen had lower peak neutralizing responses than a two-dose regimen, it achieved a similar level of neutralizing antibody responses at 1 year, an encouraging finding that shows our vaccine may be a useful tool to curb Zika epidemics,” Dr. Salisch noted. “Previous experience with the Ad26 vector platform across our investigational vaccine programs have yielded similarly promising results, most recently with our investigational Janssen COVID-19 vaccine program, for which phase 3 data show a single-dose vaccine met all primary and key secondary endpoints,” she said.
“The biggest barrier [to further development of the candidate vaccine] is one that we actually consider ourselves fortunate to have: The very low incidence of reported Zika cases currently reported worldwide,” Dr. Salisch said. “However, the current Zika case rate can change at any time, and in the event the situation demands it, we are open to alternative regulatory pathways to help us glean the necessary insights on vaccine safety and efficacy to further advance the development of this candidate,” she emphasized.
As for additional research, “there are still questions surrounding Zika transmission and the pathomechanism of congenital Zika syndrome,” said Dr. Salisch. “Our hope is that a correlate of protection against Zika disease, and in particular against congenital Zika syndrome, can be identified,” she said.
Consider pregnant women in next phase of research
“A major hurdle in ZIKV vaccine development is the inability to conduct large efficacy studies in the absence of a current outbreak,” Ann Chahroudi, MD, of Emory University, Atlanta, and Sallie Permar, MD, of Weill Cornell Medicine, New York, wrote in an accompanying editorial.
The current study provided some efficacy data using a mouse model, but “these data are obviously not conclusive for human protection,” they said.
“A further challenge for ZIKV vaccine efficacy trials will be to demonstrate fetal protection from [congenital Zika syndrome] after adult immunization. There should be a clear plan to readily deploy phase 3 trials for the most promising vaccines to emerge from phase 1 and 2 in the event of an outbreak, as was implemented for Ebola, including infant follow-up,” they emphasized.
The editorialists noted that the study did not include pregnant women, who represent a major target for immunization, but they said that vaccination of pregnant women against other neonatal pathogens such as influenza and tetanus has been effective. “Candidate ZIKV vaccines proven safe in phase 1 trials should immediately be assessed for safety and efficacy in pregnant women,” they said. Although Zika infections are not at epidemic levels currently, resurgence remains a possibility and the coronavirus pandemic “has taught us that preparedness for emerging infections is crucial,” they said.
Zika vaccine research is a challenge worth pursuing
“It is important to continue Zika vaccine research because of the unpredictable nature of that infection,” Kevin Ault, MD, of the University of Kansas, Kansas City, said in an interview. “Several times Zika has gained a foothold in unexposed and vulnerable populations,” Dr. Ault said. “Additionally, there are some data about using this vector during pregnancy, and eventually this vaccine may prevent the birth defects associated with Zika infections during pregnancy, he noted.
Dr. Ault said he was not surprised by the study findings. “This is a promising early phase vaccine candidate, and this adenovirus vector has been used in other similar trials,” he said. Potential barriers to vaccine development include the challenge of conducting late phase clinical trials in pregnant women, he noted. “The relevant endpoint is going to be clinical disease, and one of the most critical populations is pregnant women,” he said. In addition, “later phase 3 trials would be conducted in a population where there is an ongoing Zika outbreak,” Dr. Ault emphasized.
The study was supported by Janssen Vaccines and Infectious Diseases.

The changing brain signature of HIV
“This shift in subcortical signatures may be contributing to the increasing range of neuropsychiatric and cognitive outcomes,” write Neda Jahanshad, PhD, University of Southern California, Los Angeles, and colleagues.
The study was published online Jan. 15 in JAMA Network Open.
Brain signature of HIV
The researchers with the HIV Working Group within the Enhancing Neuro Imaging Genetics Through Meta Analysis (ENIGMA) consortium examined structural brain associations with CD4+ T cell counts and HIV viral load.
These clinical markers are the most consistently available in studies of HIV and generalize across demographically and clinically diverse HIV-infected individuals, they point out. However, the degree to which they capture central nervous system injury is not fully understood.
In this cross-sectional study of 1,203 HIV-infected adults from 13 HIV neuroimaging studies, a lower CD4+ T-cell count was associated with smaller hippocampal and thalamic volume independent of treatment status. However, in a subset of adults not on cART, a lower CD4+ T-cell count was associated with smaller putamen volume.
Across all participants, detectable viral load was associated with smaller hippocampal volume, but in the subset on cART, detectable viral load was also associated with smaller amygdala volume.
The findings indicate that plasma markers universally used to monitor immune function and response to treatment in patients with HIV infection are associated with subcortical brain volume.
“Our findings,” they add, “extend beyond the classically implicated regions of the basal ganglia and may represent a generalizable brain signature of HIV infection in the cART era.”
A limitation of the analysis is that most of the participants were men (n = 880, 73%). “A more extensive international effort assessing the neurologic effects of HIV infection in women is needed,” they conclude.
This analysis, they add, demonstrates the feasibility and utility of a global collaborative initiative to understand the neurologic signatures of HIV infection. They invite other HIV researchers to join the ENIGMA-HIV consortium.
“With a greater collaborative effort, we will be able to assess factors that may modulate neurologic outcomes, including cART treatment regimens, comorbidities, coinfections, substance use, socioeconomic factors, and demographic factors, as well as the functional implications of such structural brain differences, in well-powered analyses,” the researchers say.
“Understanding the neurobiological changes that may contribute to neuropsychiatric and cognitive outcomes in HIV-positive individuals is critical for identifying individuals at risk for neurologic symptoms, driving novel treatments that may protect the CNS, and monitoring treatment response,” they add.
Support for this research was provided by grants from the National Institutes of Health, the SA Medical Research Council, the National Health and Medical Research Council, and the European Research Council.

CDC: 20% of people in the U.S. are infected with an STD
Among the more than 320 million people in the United States, there was a prevalence estimate of 67.6 million sexually transmitted infections at the time of assessment in 2018, according to the results of an epidemiologic study using multiple data sources, including the National Health and Nutrition Examination Survey (NHANES).
In addition, almost half of the incident STIs occurred in the 15- to 24-year age bracket, according to a report published online in Sexually Transmitted Diseases. Researchers estimated the combined number of prevalent and incident infections of eight STIs in the United States in 2018: chlamydia, gonorrhea, trichomoniasis, syphilis, genital herpes (caused by herpes simplex virus type 2 [HSV-2]), human papillomavirus (HPV), sexually transmitted hepatitis B virus (HBV), and sexually transmitted HIV.
The estimated incidences of these STIs in this update, the first since 2008, were made using more recent data and improved estimation methods to provide updated STI prevalence and incidence estimates for 2018, both overall and by disease. “Having a combined estimate is crucial for policy purposes to illustrate the importance of STIs in the United States,” according to Kristen M. Kreisel, PhD, an epidemiologist at the Centers for Disease Control and Prevention, division of STD prevention, and colleagues.
The number of prevalent and incident infections were obtained by multiplying each STI’s updated per capita estimates by the 2018 full resident population estimates from the American Community Survey.
Detailed results
Chlamydia. The prevalence of chlamydia was estimated using 2015-2018 NHANES data, which was then used to create a modeled prevalence in 2018, according to the authors. There were an estimated 2.4 million prevalent urogenital chlamydial infections among persons aged 15-39 years in 2018; 1.1 and 1.3 million infections among men and women, respectively. Individuals aged 15-24 years comprised 56.7% and 75.8% of all infections in men and women respectively.
Gonorrhea. The prevalence of gonorrhea was estimated using ordinary differential equation based modeling. The number of prevalent urogenital gonococcal infections in 2018 among 15- to 39-year-olds was 209,000 overall; 50,000 in men and 155,000 in women. Of these, 113,000 (54.1%) occurred in 15- to 24-year-olds.
Trichomoniasis. The prevalence of trichomoniasis was estimated using 2015-2018 NHANES data, which was then used to create a modeled prevalence in 2018, according to the authors. The number of prevalent Trichomonas infections among 15- to 59-year-olds was 2.6 million, with 470,000 in men and 2.1 million in women. Persons aged 15-24 years comprised 15.6% of all prevalent infections, according to the authors.
Syphilis. The number of estimated prevalent syphilitic infections (all stages) among 14- to 49-year-old persons in 2018 was 156,000, with infections in men comprising 71.8% of all infections. Infections in both men and women aged 14-24 years accounted for about 25% of all infections, with 36,000 total prevalent syphilitic infections among 14- to 24-year-olds in 2018.
Genital herpes. The prevalence of genital herpes (caused by HSV-2) was estimated using 2015-2018 NHANES data, according to the authors. In persons aged 15-49 years in 2018, there were 18.6 million prevalent HSV-2 infections; 6.4 million among men and 12.2 million among women. Infections in 15- to 24-year-olds comprised 7.1% of all prevalent HSV-2 infections.
HPV. The prevalence of HPV was estimated using 2013-2016 NHANES data, which was assumed to reflect stable prevalence in 2018, according to the authors. Among 15- to 59-year-olds, the estimated number of persons, men, and women infected with one or more disease-associated HPV types in 2018 was 42.5, 23.4, and 19.2 million, respectively, with an estimated 9.0 million (21%) 15- to 24-year-olds infected,
HBV. NHANES 2013-2018 data were used to estimate the prevalence of sexually transmitted chronic HBV infections in 2018, according to the authors. The estimated number of infections among persons aged 15 years and older in 2018 was 103,000 (51,000 men and 52,000 women). There small sample size of individuals aged 15-24 years in the NHANES database made it impossible to obtain an accurate estimate for this group, according to the authors.
HIV. Data from the National HIV Surveillance System were used to estimate the prevalence and incidence of sexually transmitted HIV infections for persons aged 13 years and older in 2018. A total of 984,000 individuals aged 13 years and older were estimated to be living with sexually transmitted HIV at the end of 2018, according to the authors. Nearly 80% were men. In the 13- to 24-year-old age bracket, there were an estimated 45,400 living with sexually transmitted HIV.
Billions in costs
Commenting on the study by the CDC researchers, Raul Romaguera, acting director for CDC’s division of STD prevention, stated in a press release: “There are significant human and financial costs associated with these infections, and we know from other studies that cuts in STI prevention efforts result in higher costs down the road. Preventing STIs could save billions in medical costs, but more importantly, prevention would improve the health and lives of millions of people.”
“About 20% of the total U.S. population had an STI at a given point in 2018, while nearly half of all incident infections occurred in people aged 15-24 years. Focusing STI prevention efforts on the 15- to 24-year-old population may be key to lowering the STI burden in the U.S.,” the researchers concluded.
The authors reported that they had no disclosures.
Among the more than 320 million people in the United States, there was a prevalence estimate of 67.6 million sexually transmitted infections at the time of assessment in 2018, according to the results of an epidemiologic study using multiple data sources, including the National Health and Nutrition Examination Survey (NHANES).
In addition, almost half of the incident STIs occurred in the 15- to 24-year age bracket, according to a report published online in Sexually Transmitted Diseases. Researchers estimated the combined number of prevalent and incident infections of eight STIs in the United States in 2018: chlamydia, gonorrhea, trichomoniasis, syphilis, genital herpes (caused by herpes simplex virus type 2 [HSV-2]), human papillomavirus (HPV), sexually transmitted hepatitis B virus (HBV), and sexually transmitted HIV.

FROM SEXUALLY TRANSMITTED DISEASES
Family physicians can help achieve national goals on STIs
Among these are the U.S. Department of Health and Human Services’ first “Sexually Transmitted Infections (STIs) National Strategic Plan for the United States,” which has a strong encompassing vision.
“The United States will be a place where sexually transmitted infections are prevented and where every person has high-quality STI prevention care, and treatment while living free from stigma and discrimination. The vision includes all people, regardless of age, sex, gender identity, sexual orientation, race, ethnicity, religion, disability, geographic location, or socioeconomic circumstance,” the new HHS plan states.1
Family physicians can and should play important roles in helping our country meet this plan’s goals particularly by following two important updated clinical guidelines, one from the U.S. Preventive Services Task Force (USPSTF) and another from the Centers for Disease Control and Prevention (CDC).
This strategic plan includes the following five overarching goals with associated objectives:
- Prevent New STIs.
- Improve the health of people by reducing adverse outcomes of STIs.
- Accelerate progress in STI research, technology, and innovation.
- Reduce STI-related health disparities and health inequities.
- Achieve integrated, coordinated efforts that address the STI epidemic.1
In my opinion, family physicians have important roles to play in order for each of these goals to be achieved.Unfortunately, there are approximately 20 million new cases of STIs each year, and the U.S. has seen increases in the rates of STIs in the past decade.
“Sexually transmitted infections are frequently asymptomatic, which may delay diagnosis and treatment and lead persons to unknowingly transmit STIs to others,” according to a new recommendation statement from the USPSTF.2 STIs may lead to serious health consequences for patients, cause harms to a mother and infant during pregnancy, and lead to cases of cancer among other concerning outcomes. As such, following the HHS new national strategic plan is critical for us to address the needs of our communities.
Preventing new STIs
Family physicians can be vital in achieving the first goal of the plan by helping to prevent new STIs. In August 2020, the USPSTF updated its guideline on behavioral counseling interventions to prevent STIs. In my opinion, the USPSTF offers some practical improvements from the earlier version of this guideline.
The task force provides a grade B recommendation that all sexually active adolescents and adults at increased risk for STIs be provided with behavioral counseling to prevent STIs. The guideline indicates that behavioral counseling interventions reduce the likelihood of those at increased risk for acquiring STIs.2
The 2014 guideline had recommended intensive interventions with a minimum of 30 minutes of counseling. Many family physicians may have found this previous recommendation impractical to implement. These updated recommendations now include a variety of interventions, such as those that take less than 30 minutes.
Although interventions with more than 120 minutes of contact time had the most effect, those with less than 30 minutes still demonstrated statistically significant fewer acquisitions of STIs during follow-up. These options include in-person counseling, and providing written materials, websites, videos, and telephone and text support to patients. These interventions can be delivered directly by the family physician, or patients may be referred to other settings or the media interventions.
The task force’s updated recommendation statement refers to a variety of resources that can be used to identify these interventions. Many of the studies reviewed for this guideline were conducted in STI clinics, and the guideline authors recommended further studies in primary care as opportunities for more generalizability.
In addition to behavioral counseling for STI prevention, family physicians can help prevent STIs in their patients through HPV vaccination and HIV pre-exposure prophylaxis (PrEP provision) within their practices. As the first contact for health care for many patients, we have an opportunity to significantly impact this first goal of prevention.
Treating STIs
Within the second goal of the national strategic plan is treatment of STIs, which family physicians should include in their practices as well as the diagnosis of STIs.
In December 2020, an update to the CDC’s treatment guideline for gonococcal infection was released. Prior to the publishing of this updated recommendation, the CDC recommended combination therapy of 250 mg intramuscular (IM) dose of ceftriaxone and either doxycycline or azithromycin. This recommendation has been changed to a single 500-mg IM dose of ceftriaxone for uncomplicated urogenital, anorectal, and pharyngeal gonorrhea. If chlamydia cannot be excluded, then the addition of oral doxycycline 100 mg twice daily for 7 days is recommended for nonpregnant persons, and 1 g oral azithromycin for pregnant persons. The previous treatment was recommended based on a concern for gonococcal resistance.
This updated guideline reflects increasing concerns for antimicrobial stewardship and emerging azithromycin resistance. It does not recommend a test-of-cure for urogenital or rectal gonorrhea, though did recommend a test-of-cure 7-14 days after treatment of pharyngeal gonorrhea. The guideline also recommends testing for reinfection 3-12 months after treatment as the rate of reinfection ranges from 7% to 12% among those previously treated.3
For some offices, the provision of the IM injection may be challenging, though having this medication in stock with the possibility of provision can greatly improve access and ease of treatment for patients. Family physicians can incorporate these updated recommendations along with those for other STIs such as chlamydia and syphilis with standing orders for treatment and testing within their offices.
Accelerating progress in STI research
Family physicians can also support the national strategic plan by participating in studies looking at the impact of behavioral counseling in the primary care office as opposed to in STI clinics. In addition, by following the STI treatment and screening guidelines, family physicians will contribute to the body of knowledge of prevalence, treatment failure, and reinfection rates of STIs. We can also help advance the research by providing feedback on interventions that have success within our practices.
Reducing STI-related health disparities and inequities
Family physicians are also in important places to support the strategic plan’s fourth goal of reducing health disparities and health inequities.
If we continue to ask the questions to identify those at high risk and ensure that we are offering appropriate STI prevention, care, and treatment services within our clinics, we can expand access to all who need services and improve equity. By offering these services within the primary care office, we may be able to decrease the stigma some may feel going to an STI clinic for services.
By incorporating additional screening and counseling in our practices we may identify some patients who were not aware that they were at risk for an STI and offer them preventive services.
Achieving integrated and coordinated efforts
Finally, as many family physicians have integrated practices, we are uniquely poised to support the fifth goal of the strategic plan of achieving integrated and coordinated efforts addressing the STI epidemic. In our practices we can participate in, lead, and refer to programs for substance use disorders, viral hepatitis, STIs, and HIV as part of full scope primary care.
Family physicians and other primary care providers should work to support the entire strategic plan to ensure that we are fully caring for our patients and communities and stopping the past decade’s increase in STIs. We have an opportunity to use this strategy and make a large impact in our communities.

Among these are the U.S. Department of Health and Human Services’ first “Sexually Transmitted Infections (STIs) National Strategic Plan for the United States,” which has a strong encompassing vision.
“The United States will be a place where sexually transmitted infections are prevented and where every person has high-quality STI prevention care, and treatment while living free from stigma and discrimination. The vision includes all people, regardless of age, sex, gender identity, sexual orientation, race, ethnicity, religion, disability, geographic location, or socioeconomic circumstance,” the new HHS plan states.1
Family physicians can and should play important roles in helping our country meet this plan’s goals particularly by following two important updated clinical guidelines, one from the U.S. Preventive Services Task Force (USPSTF) and another from the Centers for Disease Control and Prevention (CDC).
This strategic plan includes the following five overarching goals with associated objectives:
- Prevent New STIs.
- Improve the health of people by reducing adverse outcomes of STIs.
- Accelerate progress in STI research, technology, and innovation.
- Reduce STI-related health disparities and health inequities.
- Achieve integrated, coordinated efforts that address the STI epidemic.1
In my opinion, family physicians have important roles to play in order for each of these goals to be achieved.Unfortunately, there are approximately 20 million new cases of STIs each year, and the U.S. has seen increases in the rates of STIs in the past decade.
“Sexually transmitted infections are frequently asymptomatic, which may delay diagnosis and treatment and lead persons to unknowingly transmit STIs to others,” according to a new recommendation statement from the USPSTF.2 STIs may lead to serious health consequences for patients, cause harms to a mother and infant during pregnancy, and lead to cases of cancer among other concerning outcomes. As such, following the HHS new national strategic plan is critical for us to address the needs of our communities.
Preventing new STIs
Family physicians can be vital in achieving the first goal of the plan by helping to prevent new STIs. In August 2020, the USPSTF updated its guideline on behavioral counseling interventions to prevent STIs. In my opinion, the USPSTF offers some practical improvements from the earlier version of this guideline.
The task force provides a grade B recommendation that all sexually active adolescents and adults at increased risk for STIs be provided with behavioral counseling to prevent STIs. The guideline indicates that behavioral counseling interventions reduce the likelihood of those at increased risk for acquiring STIs.2
The 2014 guideline had recommended intensive interventions with a minimum of 30 minutes of counseling. Many family physicians may have found this previous recommendation impractical to implement. These updated recommendations now include a variety of interventions, such as those that take less than 30 minutes.
Although interventions with more than 120 minutes of contact time had the most effect, those with less than 30 minutes still demonstrated statistically significant fewer acquisitions of STIs during follow-up. These options include in-person counseling, and providing written materials, websites, videos, and telephone and text support to patients. These interventions can be delivered directly by the family physician, or patients may be referred to other settings or the media interventions.
The task force’s updated recommendation statement refers to a variety of resources that can be used to identify these interventions. Many of the studies reviewed for this guideline were conducted in STI clinics, and the guideline authors recommended further studies in primary care as opportunities for more generalizability.
In addition to behavioral counseling for STI prevention, family physicians can help prevent STIs in their patients through HPV vaccination and HIV pre-exposure prophylaxis (PrEP provision) within their practices. As the first contact for health care for many patients, we have an opportunity to significantly impact this first goal of prevention.
Treating STIs
Within the second goal of the national strategic plan is treatment of STIs, which family physicians should include in their practices as well as the diagnosis of STIs.
In December 2020, an update to the CDC’s treatment guideline for gonococcal infection was released. Prior to the publishing of this updated recommendation, the CDC recommended combination therapy of 250 mg intramuscular (IM) dose of ceftriaxone and either doxycycline or azithromycin. This recommendation has been changed to a single 500-mg IM dose of ceftriaxone for uncomplicated urogenital, anorectal, and pharyngeal gonorrhea. If chlamydia cannot be excluded, then the addition of oral doxycycline 100 mg twice daily for 7 days is recommended for nonpregnant persons, and 1 g oral azithromycin for pregnant persons. The previous treatment was recommended based on a concern for gonococcal resistance.
This updated guideline reflects increasing concerns for antimicrobial stewardship and emerging azithromycin resistance. It does not recommend a test-of-cure for urogenital or rectal gonorrhea, though did recommend a test-of-cure 7-14 days after treatment of pharyngeal gonorrhea. The guideline also recommends testing for reinfection 3-12 months after treatment as the rate of reinfection ranges from 7% to 12% among those previously treated.3
For some offices, the provision of the IM injection may be challenging, though having this medication in stock with the possibility of provision can greatly improve access and ease of treatment for patients. Family physicians can incorporate these updated recommendations along with those for other STIs such as chlamydia and syphilis with standing orders for treatment and testing within their offices.
Accelerating progress in STI research
Family physicians can also support the national strategic plan by participating in studies looking at the impact of behavioral counseling in the primary care office as opposed to in STI clinics. In addition, by following the STI treatment and screening guidelines, family physicians will contribute to the body of knowledge of prevalence, treatment failure, and reinfection rates of STIs. We can also help advance the research by providing feedback on interventions that have success within our practices.
Reducing STI-related health disparities and inequities
Family physicians are also in important places to support the strategic plan’s fourth goal of reducing health disparities and health inequities.
If we continue to ask the questions to identify those at high risk and ensure that we are offering appropriate STI prevention, care, and treatment services within our clinics, we can expand access to all who need services and improve equity. By offering these services within the primary care office, we may be able to decrease the stigma some may feel going to an STI clinic for services.
By incorporating additional screening and counseling in our practices we may identify some patients who were not aware that they were at risk for an STI and offer them preventive services.
Achieving integrated and coordinated efforts
Finally, as many family physicians have integrated practices, we are uniquely poised to support the fifth goal of the strategic plan of achieving integrated and coordinated efforts addressing the STI epidemic. In our practices we can participate in, lead, and refer to programs for substance use disorders, viral hepatitis, STIs, and HIV as part of full scope primary care.
Family physicians and other primary care providers should work to support the entire strategic plan to ensure that we are fully caring for our patients and communities and stopping the past decade’s increase in STIs. We have an opportunity to use this strategy and make a large impact in our communities.

Prophylactic HIV treatment in female STI patients is rare
reported Kirk D. Henny, PhD, and colleagues of the Centers for Disease Control and Prevention.
In an effort to quantify HIV testing rates as well as the rate of pre-exposure prophylaxis (PrEP) among women with gonorrhea or syphilis, Dr. Henny and his colleagues performed a multivariate logistic regression analysis of 13,074 female patients aged 15-64 diagnosed with a STI in the absence of HIV. Data was pulled in 2017 from the IBM MarketScan commercial and Medicaid insurance databases, and the research was published in Obstetrics & Gynecology.
Medicaid patients were more likely to be tested for HIV
A total of 3,709 patients with commercial insurance were diagnosed with gonorrhea and 1,696 with syphilis. Among those with Medicaid, 6,172 were diagnosed with gonorrhea and 1,497 with syphilis. Medicaid patients diagnosed with either STI were more likely to be tested for HIV than the commercially insured patients. With an adjusted prevalence ratio, patients commercially insured with had either STI were more likely to be tested for HIV than patients who had no STI. Prophylactic treatment rates were similar in both insurance groups: 0.15% in the commercial insurance group and 0.26% in the Medicaid group. No patient from either group who was diagnosed with gonorrhea or syphilis and subsequently tested for HIV received pre-exposure prophylactic (PrEP) treatment.
STI diagnosis is a significant indicator of future HIV
Female patients diagnosed with either STI are more likely to contract HIV, the researchers noted. They cautioned that their findings of low HIV testing rates and the absence of prophylactic treatment means that “these missed opportunities for health care professionals to intervene with female patients diagnosed with gonorrhea or syphilis might have contributed to HIV infections that could have been averted.”
The researchers also pointed out that, in a recent analysis of pharmacy data, prophylactic prescribing for female patients with clinical indications for PrEP was 6.6%, less than one-third the coverage provided to male patients.
Future research should target understanding “individual and contextual factors associated with low HIV testing” and PrEP treatment in female patients, especially those with STIs, Dr. Henny and his colleagues advised.
In a separate interview, Constance Bohon, MD FACOG, observed: “The authors present data to document the low incidence of pre-exposure prophylaxis in women who are at substantial risk of acquiring HIV and possible causes for the low utilization of this treatment.” It is important to identify barriers to diagnosis, counseling, and treatment, she advised.
“Multicenter studies to determine the best methodologies to improve the identification, management, and treatment of these at-risk women need to be done, and the conclusions disseminated to health care providers caring for women,” Dr. Bohon said.
PrEP is an important, simple strategy for reducing HIV transmission
“Pre-exposure prophylaxis has been demonstrated to decrease HIV acquisition in those at risk by up to 90% when taken appropriately,” and yet prescribing rates are extremely low (2%-6%) in at-risk women and especially women of color. These disparities have only grown over time, with prophylactic prescriptions for women at 5% between 2012 and 2017, compared with 68% for men, Catherine S. Eppes, MD, MPH, and Jennifer McKinney, MD, MPH, said in a related editorial commenting on the Research Letter by Dr. Henny and colleagues in Obstetrics & Gynecology (2020 Dec;136[6]:1080-2).
Given the abundant research demonstrating the importance and ease of prescribing PrEP, the question remains: “why does preexposure prophylaxis uptake remain so low, especially for women and women of color? There are three important issues about preexposure prophylaxis raised by this study: the research gap, the implementation gap, and the effect of systemic racism and bias,” noted Dr. Eppes and Dr. McKinney.
Women constitute a significant portion of the population that would benefit from HIV-prevention strategies, yet they continue to be excluded from research, they noted. “Much focus on research into barriers and implementation interventions for preexposure prophylaxis have focused on men who have sex with men and transgender women,” the authors of the editorial wrote.
Most women eligible for treatment would be willing to consider it if they were aware of the option, but numerous studies have cited a lack of awareness, especially among high-risk women of color in the United States, Dr. Eppes and Dr. McKinney noted.
Clinicians also need to add it to their growing checklist of mandatory appointment discussion topics, the editorialists said. “We propose standardized inclusion of preexposure prophylaxis counseling during reproductive healthcare visits. This could be aided through an electronic medical record-based best practice advisory alert. … Standardized order sets with the medication and laboratory studies necessary for safe monitoring could facilitate ease of incorporating into routine visits,” they suggested.
“Preexposure prophylaxis is extremely effective in preventing HIV, is safe, and is the only prevention method that leaves control entirely in the hands of the female partner. As a specialty, we have a responsibility to make sure our patients know about this option,” the editorialists concluded.
The authors had no financial disclosures to report. Dr. Bohon had no conflicts of interest to report.

Harnessing the HIV care continuum model to improve HCV treatment success
Better linkage to care with providers who are familiar with both the HCV and HIV treatment cascade may not only improve access to HCV treatment, but it may also support patient retention, treatment adherence, and achievement of sustained virologic response (SVR) and viral suppression, said Stephanie LaMoy, CAN Community Health, North Point, Florida. She presented the results of a pilot study at the virtual Association of Nurses in AIDS Care 2020 Annual Meeting.
In an effort to identify strategies most important for improving care access among their patients with HCV, LaMoy and her colleagues assessed 12-month patient data collected from three of their clinics. These data were evaluated for HCV treatment access, engagement, and outcomes.
The pilot study included 126 patients who were reactive and another 24 HCV-positive patients who were referred from other sources. Active HCV infections requiring treatment were reported in 144 patients.
A total of 59 patients were linked to care but did not initiate treatment for their active infection. LaMoy said there were multiple causes, including homelessness, substance abuse, and inability to maintain contact.
In contrast, 85 patients with HCV infection started treatment, but 35 of these patients did not complete their regimen. Out of the 50 patients who reported completing treatment, 30 did not return to the clinic to confirm sustained viral suppression.
According to LaMoy, this raised a red flag, causing the investigators to consider a different approach to care.
HIV care continuum model and its role in HCV
To improve the rate at which patients with HCV infection complete treatment within their clinics, the researchers formed a panel to determine necessary interventions that could reduce barriers to care.
The HIV care continuum came into play. They chose this model based on knowledge that HCV and HIV share the same care continuum with similar goals in diagnosis, linkage to care, retention, and suppression.
Based on the consensus of the panel and consideration of the HIV care continuum model, they identified a number of interventions needed to mitigate HCV treatment barriers. These included the incorporation of peer navigators or linkage-to-care (LCC) coordinators, use of the mobile medical unit, greater implementation of onsite lab visits, and medication-assisted treatment.
The LCC coordinators proved to be particularly important, as these team members helped assist patients with social and financial support to address challenges with access to treatment. These coordinators can also help patients gain access to specialized providers, ultimately improving the chance of successful HCV management.
Additionally, LCC coordinators may help identify and reduce barriers associated with housing, transportation, and nutrition. Frequent patient contact by the LCC coordinators can encourage adherence and promote risk reduction education, such as providing referrals to needle exchange services.
“Linking individuals to care with providers who are familiar with the treatment cascade could help improve retention and should be a top priority for those involved in HCV screening and treatment,” said LaMoy. “An environment with knowledge, lack of judgment, and a tenacious need to heal the community that welcomes those with barriers to care is exactly what is needed for the patients in our program.”
National, community challenges fuel barriers to HCV treatment access
Substance use, trauma histories, and mental health problems can negatively affect care engagement and must be addressed before the benefits of HCV therapy can be realized.
Addressing these issues isn’t always easy, said Kathleen Bernock, FNP-BC, AACRN, AAHIVS, of the Bedford-Stuyvesant Family Health Center in New York City, in an email to Medscape Medical News. She pointed out that several states have harsh restrictions on who is able to access HCV treatment, and some states will not approve certain medications for people who actively use drugs.
“Even for states without these restrictions, many health systems are difficult to navigate and may not be welcoming to persons actively using,” said Bernock. Trauma-informed care can also be difficult to translate into clinics, she added.
“Decentralizing care to the communities most affected would greatly help mitigate these barriers,” suggested Bernock. Decentralization, she explained, might include co-locating services such as syringe exchanges, utilizing community health workers and patient navigators, and expanding capacity-to-treat to community-based providers.
“[And] with the expansion of telehealth services in the US,” said Bernock, “we now have even more avenues to reach people that we never had before.”
LaMoy and Bernock have disclosed no relevant financial relationships.

“Linking individuals to care with providers who are familiar with the treatment cascade could help improve retention and should be a top priority for those involved in HCV screening and treatment,” said LaMoy. “An environment with knowledge, lack of judgment, and a tenacious need to heal the community that welcomes those with barriers to care is exactly what is needed for the patients in our program.”
National, community challenges fuel barriers to HCV treatment access
Substance use, trauma histories, and mental health problems can negatively affect care engagement and must be addressed before the benefits of HCV therapy can be realized.
Addressing these issues isn’t always easy, said Kathleen Bernock, FNP-BC, AACRN, AAHIVS, of the Bedford-Stuyvesant Family Health Center in New York City, in an email to Medscape Medical News. She pointed out that several states have harsh restrictions on who is able to access HCV treatment, and some states will not approve certain medications for people who actively use drugs.
“Even for states without these restrictions, many health systems are difficult to navigate and may not be welcoming to persons actively using,” said Bernock. Trauma-informed care can also be difficult to translate into clinics, she added.
“Decentralizing care to the communities most affected would greatly help mitigate these barriers,” suggested Bernock. Decentralization, she explained, might include co-locating services such as syringe exchanges, utilizing community health workers and patient navigators, and expanding capacity-to-treat to community-based providers.
“[And] with the expansion of telehealth services in the US,” said Bernock, “we now have even more avenues to reach people that we never had before.”
LaMoy and Bernock have disclosed no relevant financial relationships.
