STIs

A 32-year-old woman had sex with a man she met while on vacation 6 weeks ago. She was intoxicated at the time and does not know much about the person. She recalls having engaged in vaginal intercourse without a condom. She does not have any symptoms.

She previously received baseline lab testing per Centers for Disease Control and Prevention guidelines 2 years ago with a negative HIV test and negative hepatitis C test. She asks for testing for STIs. What would you recommend?

A. HIV, hepatitis C, gonorrhea, chlamydia, and human papillomavirus

B. HIV, hepatitis C, gonorrhea, chlamydia, and herpes simplex virus

C. HIV, hepatitis C, gonorrhea, and chlamydia

D. HIV, gonorrhea, and chlamydia

E. Gonorrhea and chlamydia

HIV risk estimate

The most practical answer is E, check for gonorrhea and chlamydia. Many protocols in place for evaluating people for STIs will test for hepatitis C as well as HIV with single exposures. In this column, we will look at the lack of evidence of heterosexual sexual transmission of hepatitis C.

In regards to HIV risk, the estimated risk of transmission male to female from an HIV-infected individual is 0.08% per sexual encounter.¹ The prevalence in the United States – where HIV occurs in about 0.5% of the adult population – was used to estimate the risk of a person with unknown HIV status acquiring HIV. The calculated risk from one sexual encounter would be 0.0004 (1 in 250,000).
 

Studies of hepatitis C transmission

Tahan and colleagues did a prospective study of 600 heterosexual couples where one partner had hepatitis C and the other didn’t. Over a mean of 3 years of follow-up, none of the seronegative spouses developed hepatitis C.²

Terrault and colleagues completed a cross-sectional study of hepatitis C virus (HCV)–positive individuals and their monogamous heterosexual partners to evaluate risk of sexual transmission of HCV.³ Based on 8,377 person-years of follow-up, the estimated maximum transmission rate was 0.07%/year, which was about 1/190,000 sexual contacts. No specific sexual practices were associated with transmission. The authors of this study concurred with CDC recommendations that persons with HCV infection in long-term monogamous relationships need not change their sexual practices.⁴

Vandelli and colleagues followed 776 heterosexual partners of HCV-infected individuals over 10 years.⁵ None of the couples reported condom use. Over the follow up period, three HCV infections occurred, but based on discordance of the typing of viral isolates, sexual transmission was excluded.

Jin and colleagues completed a systematic review of studies looking at possible sexual transmission of HCV in gay and bisexual men.⁶ HIV-positive men had a HCV incidence of 6.4 per 1,000 person-years, compared with 0.4 per 1000 person-years in HIV-negative men. The authors discussed several possible causes for increased transmission risk in HIV-infected individuals including coexisting STIs and higher HCV viral load in semen of HIV-infected individuals, as well as lower immunity.
 

Summary

In hepatitis C–discordant heterosexual couples, hepatitis C does not appear to be sexually transmitted.

The risk of sexual transmission of hepatitis C to non–HIV-infected individuals appears to be exceedingly low.

NEW YORK (Reuters) – A one-week course of doxycycline was superior to a single dose of azithromycin in women with concurrent vaginal and anorectal chlamydia infection in an unblinded randomized controlled trial, mirroring previous results in men.

Researchers suggest that doxycycline should be the first-line therapy for chlamydia infection in women.

“It is clear we must consider that any woman with a urogenital infection must have an effective treatment for the anal infection, since nearly 80% of women have an anal infection concomitant with the vaginal infection,” Dr. Bertille de Barbeyrac of the University of Bordeaux, France, told Reuters Health by email.

However, she noted that “even [though] the study shows that doxycycline is more effective than azithromycin on anal infection, other studies are needed to prove that residual anal infection after treatment with azithromycin can be a source of vaginal contamination and therefore justify changing practices and eliminating azithromycin as a treatment for lower urogenital chlamydial infection in women.”

“There are other reasons [to make] this change,” she added, “such as the acquisition of macrolide resistance by M. genitalium following heavy use of azithromycin.”

As reported in The Lancet Infectious Diseases, Dr. Barbeyrac and colleagues randomly assigned 460 women (median age, 21) to either doxycycline or azithromycin in a multicenter, open-label superiority trial.

Participants received either azithromycin (a single 1-g dose, with or without food) or doxycycline (100 mg in the morning and evening at mealtimes for 7 days – that is, 100 mg of doxycycline twice daily).

The primary outcome was that the microbiological anorectal cure rate, defined as a C. trachomatis-negative nucleic acid amplification test (NAAT), resulted in anorectal specimens six weeks after treatment initiation among women who had a baseline positive result (about half the women in each treatment group).

Ninety-four percent of the doxycycline group versus 85% of the azithromycin group had an anorectal cure (adjusted odds ratio with imputation of missing values, 0.43).

Adverse events possibly related to treatment occurred in 11% of the doxycycline group versus 13% of the azithromycin group. Gastrointestinal disorders were most frequent, occurring in 8% of the doxycycline and 11% of the azithromycin groups.

Summing up, the authors write, “The microbiological anorectal cure rate was significantly lower among women who received a single dose of azithromycin than among those who received a 1-week course of doxycycline. This finding suggests that doxycycline should be the first-line therapy for C trachomatis infection in women.”

Dr. Meleen Chuang, medical director of women’s health at the Family Health Centers at NYU Langone, Brooklyn, commented in an email to Reuters Health that after reviewing this study “as well as CDC and WHO recommendations updated as of 2022, health care providers should be treating C. trachomatis infections with doxycycline 100 mg twice a day for seven days as first-line therapy rather than azithromycin, [given] concerns of increasing macrolide drug resistance against Mycoplasma genitalium and Neisseria gonorrhea.”

“Our clinicians also see the growing uptick of syphilis, gonorrhea, and chlamydia infections in our population, similarly to the rest of the United States since 2020,” she noted. “With the increase in STD infection ... treatment with doxycycline therapy with an important caveat to the patient to complete the one-week treatment regimen is extremely important.”

Dr. Latasha Murphy of the Gynecologic Care Institute at Mercy, Baltimore, also commented in an email to Reuters Health. She noted, “this study does not mirror my clinical experience. More patients have side effects from doxycycline than azithromycin in my experience. Also, anorectal screening is not routine in STD screening.”

“If any major changes to clinical care are made,” she said, “it may be for more consistent screening for anorectal disease. This may ultimately lead to doxycycline being the first line-treatment. More research is needed before making any definitive changes.”

Imiquimod cream is a safe, effective, first-line alternative to surgery for the treatment of vulvar high-grade squamous intraepithelial lesions (vHSILs), suggest the results from the first randomized trial to compare the two approaches directly.

The findings provide women with human papillomavirus (HPV)–related precancerous lesions with a new treatment option that can circumvent drawbacks of surgery, according to first author Gerda Trutnovsky, MD, deputy head of the Division of Gynecology at the Medical University of Graz, Austria.

“Surgical removal of [vulvar intraepithelial neoplasia] can cause wound healing disorders, scarring, and even sexual complaints later on,” she explained in a press statement. Further, recurrences are common, and repeat surgeries are often necessary, she said.

The results from the trial show that “imiquimod cream was effective and well tolerated, and the rate of success of this treatment equaled that of surgery,” Dr. Trutnovsky said.

The study was published online in The Lancet.

The findings are of note because HPV vaccination rates remain low, and the incidence of both cervical and vulvar intraepithelial neoplasia has increased in recent years, particularly among younger women, the authors comment.
 

First head-to-head trial

For the trial, Dr. Trutnovsky and her colleagues randomly assigned 110 women with vHSIL to receive either imiquimod treatment or surgery between June 2013 and January 2020. Of these patients, 78% had unifocal lesions, and 22% had multifocal lesions.

The participants (aged 18-90 years) were recruited from six hospitals in Austria. All had histologically confirmed vHSIL with visible unifocal or multifocal lesions. Those with suspected invasive disease, a history of vulvar cancer or severe inflammatory dermatosis of the vulva, or who had undergone active treatment for vHSIL in the prior 3 months were excluded.

Imiquimod treatment was self-administered. The dose was slowly escalated to no more than three times per week for 4-6 months. Surgery involved either excision or ablation.

The team reports that 98 patients (of the 110 who were randomly assigned) completed the study: 46 in the imiquinod arm and 52 in the surgery arm.

Complete clinical response rates at 6 months were 80% with imiquimod versus 79% with surgery. No significant difference was observed between the groups with respect to HPV clearance, adverse events, and treatment satisfaction, the authors report.

“Long-term follow-up ... is ongoing and will assess the effect of treatment modality on recurrence rates,” the team comments.

Dr. Trutnovsky and colleagues recommend that patients with vHSIL be counseled regarding the potential benefits and risks of treatment options. “On the basis of our results, the oncological safety of imiquimod treatment can be assumed as long as regular clinical check-ups are carried out,” they write.

They also note that good patient compliance is important for treatment with imiquimod to be successful and that surgery might remain the treatment of choice for patients who may not be adherent to treatment.

“In all other women with vHSIL, imiquimod can be considered a first-line treatment option,” the authors conclude.

The study was funded by the Austrian Science Fund and Austrian Gynaecological Oncology group. The authors have disclosed no relevant financial relationships.

Dr. Trutnovsky and colleagues recommend that patients with vHSIL be counseled regarding the potential benefits and risks of treatment options. “On the basis of our results, the oncological safety of imiquimod treatment can be assumed as long as regular clinical check-ups are carried out,” they write.

They also note that good patient compliance is important for treatment with imiquimod to be successful and that surgery might remain the treatment of choice for patients who may not be adherent to treatment.

“In all other women with vHSIL, imiquimod can be considered a first-line treatment option,” the authors conclude.

The study was funded by the Austrian Science Fund and Austrian Gynaecological Oncology group. The authors have disclosed no relevant financial relationships.

The wide majority of at-home sexually transmitted infection testing kits in the United States appear to be limited to use by adults, a new study finds, and many have limitations that make them less than ideal for young people to use.

While at-home kits do allow more access to STI testing, “we need to create programs that are specific for youth because they have extra needs,” said lead author Saumya Sao, a research assistant at the department of gynecology & obstetrics at Johns Hopkins University, Baltimore, in an interview. “The only platform that did meet our needs was the program that we developed specifically.”

The findings were released ahead of the study’s scheduled presentation at the 2022 annual clinical and scientific meeting of the American College of Obstetricians and Gynecologists (Session A117).

According to Ms. Sao, companies began to offer more at-home testing kits during the pandemic as in-person STI clinics shut down. Still, “the fact that we only found 13 self-collect mail-in STI programs shows you that this is pretty new,” she said. “There are not too many companies that do it. We found a lot more platforms that allow users to place orders for testing online, but you’re still required to go into a lab and actually do the testing.”

The researchers gathered information about 13 programs, including the one that they developed at Johns Hopkins known as Violet. Of those, seven limited testing to adults aged 18 and up, and one didn’t list an age requirement. The rest had some age requirements (such as 14 and up) or no age requirements.

The lack of full access for teens is problematic, Ms. Sao said. According to the study, “access to testing among young people is especially important because youth (ages 13-24) bear a disproportionate burden of sexually transmitted infection, accounting for 50% of cases but only 25% of the sexually active population.”

Research has suggested that young people are often wary of visiting STI clinics because they fear stigma from medical professionals or worry about being seen there, Ms. Sao said.

Tests are free in only three of the programs analyzed in the new study. Among the other programs, tests for Chlamydia trachomatis and Neisseria gonorrhoeae cost $45-$179; only two accepted insurance. “These out-of-pocket costs are really high in regard to what a young person might be able to afford for testing, especially if they would need to do repeat testing between partners, or 3 months after testing positive,” Ms. Sao said.

Most of the programs will link users to medical professionals if they test positive. This is a key feature, Ms. Sao said, in order to make sure young people have support.

As for location, most of the programs – including all those that offer free testing – are limited to certain states. Planned Parenthood, for example, only offers at-home STI testing in Maine, New Hampshire, and Vermont. The program charges patients on a sliding scale, accepts insurance, and is available for ages 14 and up. It connects users who test positive to physicians.

Another free program, TakeMeHome, is restricted to 16 states. It includes an HIV panel for ages 17+ (although it doesn’t have vaginal swab testing). It recommends that patients who are positive consult a doctor.

The researchers also found that some, but not all, of the programs send testing material in discreet packaging. This is important to young people because they may not want their parents to know that they’re getting tested.

Some of the testing programs analyzed don’t make it clear on their web sites whether their packaging is discreet, Ms. Sao said.

At Johns Hopkins, Ms. Sao has helped develop the Violet Project, which is designed to meet the needs of young people and offers free STI testing to residents of Maryland of any age for Chlamydia trachomatis, Neisseria gonorrhoeae, and Trichomonas vaginalis. Mailing packages are discreet, and physicians reach out to those who test positive. Fees are covered.

“We don’t have money yet to expand beyond Maryland, but we’re hopeful,” she said.

In an interview, Loma Linda (Calif.) University Health maternal-fetal medicine specialist Sarah Smithson, DO, MS, praised the study and said she supports optimizing at-home testing for young people. It may be useful for youths who first get tested in a clinic but then need follow-up testing or testing of their partners, she said.

Dr. Smithson added that transportation is often a challenge for young people. At her pregnancy clinic in California’s Inland Empire, she said, some patients live in remote areas and make virtual doctor visits because of the distance. STI testing is crucial for pregnant women, she said, “and this could be a game changer for them.”

The incidence of sexually transmitted infection (STI) as well as disability-adjusted life-years (DALYs) increased worldwide over 30 years, according to an observational trend study from China.

“Most countries had a decrease in age-standardized rates of incidence and DALY for STIs, whereas the absolute incident cases and DALYs increased from 1990 to 2019,” the authors write in The Lancet Infectious Diseases. “Therefore, STIs still represent a global public health challenge, especially in sub-Saharan Africa and Latin America, where more attention and health prevention services are warranted.”

“Our study also suggested an upward trend of age-standardized incidence rates among young populations, especially for syphilis, after 2010,” they add.
 

STIs are a major worldwide public health challenge

To assess global STI burden and trends, co–lead study author Yang Zheng, MD, of Zhejiang University School of Medicine in Hangzhou, China, and colleagues analyzed data from the Global Burden of Disease (GBD) study 2019.

They calculated incidence and DALYs of STIs in the general population at national, regional, and global levels over 30 years. They also calculated annual percentage changes in the age-standardized incidence rate and the age-standardized DALY rate of the five STIs included in the GBD study.

Of 204 countries in GBD 2019, 161 provided data on syphilis, 64 on gonorrhea, 94 on chlamydia, 56 on trichomonas, and 77 on genital herpes. The authors included 95% uncertainty intervals (UIs) and used Bayesian meta-regression to model the data.

• Overall, they found that the global age-standardized incidence rate of STIs trended downward, with an estimated annual percentage change of –0.04 (95% UI, –0.08 to 0.00) from 1990 to 2019, reaching 9,535.71 per 100,000 person-years (8,169.73-11,054.76) in 2019.
• The age-standardized DALY rate decreased with an estimated annual percentage change of –0.92 (–1.01 to –0.84) and reached 22.74 per 100,000 person-years (14.37-37.11) in 2019.
• Sub-Saharan Africa, one of the hotspots, had the highest age-standardized incidence rate (19,973.12 per 100,000 person-years, 17,382.69-23,001.57) and age-standardized DALY rate (389.32 per 100,000 person-years, 154.27-769.74).
• The highest incidence rate was among adolescents (18,377.82 per 100,000 person-years, 14,040.38-23,443.31), with stable total STI trends except for an increase in syphilis between 2010 (347.65 per 100,000 person-years, 203.58-590.69) and 2019 (423.16 per 100,000 person-years, 235.70-659.01).
• The age-standardized incidence rate was higher among males (10,471.63 per 100,000 person-years, 8,892.20-12,176.10) than females (8,602.40 per 100,000 person-years, 7,358.00-10,001.18), whereas the age-standardized DALY rate was higher among females (33.31 per 100,000 person-years, 21.05-55.25) than males (12.11 per 100,000 person-years, 7.63-18.93).

The authors deliver a call to action

“This paper is a call to action to focus on the STI pandemic with granular data on key target populations,” Yukari C. Manabe, MD, FIDSA, FRCP, who was not involved in the study, told this news organization. “If behavioral messaging and testing in adolescents is not improved, HIV incidence rates will be impacted, and the gains that have been made in this area will be threatened.”

“Although the number of countries from which data could be culled was limited, the change in incident cases is particularly striking, with most countries showing an increase and with African countries showing the largest rise,” said Dr. Manabe, professor of medicine, international health, and molecular microbiology and immunology at Johns Hopkins Medicine and director of the Johns Hopkins Center for Innovative Diagnostics for Infectious Diseases, Baltimore.

“The increase in syphilis incidence rates, particularly in younger people, including men who have sex with men, is also alarming,” she added in an email. “It is interesting to see the gender gap grow as more countries adopt antenatal syphilis screening.”

Ken S. Ho, MD, MPH, infectious diseases specialist and medical director of the Pitt Men’s Study at the University of Pittsburgh School of Medicine, Pennsylvania, called the study’s findings a wake-up call for clinicians to discuss sexual health and wellness with their patients, to increase STI screening, and to address STI stigma.

“Overall, STI rates in most countries have trended down, but paradoxically, the number of cases may be going up, because we have more younger, sexually actively people,” Dr. Ho said in an email.

“The study helps us understand the populations most impacted by STIs and allows us to design and create public health interventions that target the most impacted communities and demographic groups,” Dr. Ho, who also was not involved in the study, added. “It allows us to reflect on how we address disparities. For example, the greater burden of disease seen in women may be due to the fact that women may not be screened and are diagnosed later.”

Dr. Ho explained that the high STI rates in sub-Saharan Africa and Latin America are thought to be due to factors such as poverty and limited access to health care, known drivers of health care disparities.

The 2016 global incidence of common STIs was estimated to be up to 563.3 million, including 6.3 million cases of syphilis, 86.9 million cases of gonorrhea, 127.2 million cases of chlamydia, 156.0 million cases of trichomonas, and 186.9 million cases of genital herpes, the authors write.

The World Health Organization aims to end the STI epidemic by 2030, they note.

The study was funded by Mega-Project of National Science and Technology for the 13th Five-Year Plan of China and the National Natural Science Foundation of China. The authors, Dr. Manabe, and Dr. Ho have disclosed no relevant financial relationships.

For example, the greater burden of disease seen in women may be due to the fact that women may not be screened and are diagnosed later.”

Dr. Ho explained that the high STI rates in sub-Saharan Africa and Latin America are thought to be due to factors such as poverty and limited access to health care, known drivers of health care disparities.

The 2016 global incidence of common STIs was estimated to be up to 563.3 million, including 6.3 million cases of syphilis, 86.9 million cases of gonorrhea, 127.2 million cases of chlamydia, 156.0 million cases of trichomonas, and 186.9 million cases of genital herpes, the authors write.

The World Health Organization aims to end the STI epidemic by 2030, they note.

The study was funded by Mega-Project of National Science and Technology for the 13th Five-Year Plan of China and the National Natural Science Foundation of China. The authors, Dr. Manabe, and Dr. Ho have disclosed no relevant financial relationships.

For a decade, the number of babies born with syphilis in the United States has surged, undeterred. Data released Apr. 12 by the Centers for Disease Control and Prevention shows just how dire the outbreak has become.

In 2012, 332 babies were born infected with the disease. In 2021, that number had climbed nearly sevenfold, to at least 2,268, according to preliminary estimates. And 166 of those babies died.

About 7% of babies diagnosed with syphilis in recent years have died; thousands of others born with the disease have faced problems that include brain and bone malformations, blindness, and organ damage.

For public health officials, the situation is all the more heartbreaking, considering that congenital syphilis rates reached near-historic modern lows from 2000 to 2012 amid ambitious prevention and education efforts. By 2020, following a sharp erosion in funding and attention, the nationwide case rate was more than seven times that of 2012.

“The really depressing thing about it is we had this thing virtually eradicated back in the year 2000,” said William Andrews, a public information officer for Oklahoma’s sexual health and harm reduction service. “Now it’s back with a vengeance. We are really trying to get the message out that sexual health is health. It’s nothing to be ashamed of.”

Even as caseloads soar, the CDC budget for STD prevention – the primary funding source for most public health departments – has been largely stagnant for two decades, its purchasing power dragged even lower by inflation.

The CDC report on STD trends provides official data on congenital syphilis cases for 2020, as well as preliminary case counts for 2021 that are expected to increase. CDC data shows that congenital syphilis rates in 2020 continued to climb in already overwhelmed states like Texas, California, and Nevada and that the disease is now present in almost every state in the nation. All but three states – Maine, New Hampshire, and Vermont – reported congenital syphilis cases in 2020.

From 2011 to 2020, congenital syphilis resulted in 633 documented stillbirths and infant deaths, according to the new CDC data.

Preventing congenital syphilis – the term used when syphilis is transferred to a fetus in utero – is from a medical standpoint exceedingly simple: If a pregnant woman is diagnosed at least a month before giving birth, just a few shots of penicillin have a near-perfect cure rate for mother and baby. But funding cuts and competing priorities in the nation’s fragmented public health care system have vastly narrowed access to such services.

The reasons pregnant people with syphilis go undiagnosed or untreated vary geographically, according to data collected by states and analyzed by the CDC.

In Western states, the largest share of cases involve women who have received little to no prenatal care and aren’t tested for syphilis until they give birth. Many have substance use disorders, primarily related to methamphetamines. “They’ve felt a lot of judgment and stigma by the medical community,” said Stephanie Pierce, MD, a maternal fetal medicine specialist at the University of Oklahoma, Oklahoma City, who runs a clinic for women with high-risk pregnancies.

In Southern states, a CDC study of 2018 data found that the largest share of congenital syphilis cases were among women who had been tested and diagnosed but hadn’t received treatment. That year, among Black moms who gave birth to a baby with syphilis, 37% had not been treated adequately even though they’d received a timely diagnosis. Among white moms, that number was 24%. Longstanding racism in medical care, poverty, transportation issues, poorly funded public health departments, and crowded clinics whose employees are too overworked to follow up with patients all contribute to the problem, according to infectious disease experts.

Doctors are also noticing a growing number of women who are treated for syphilis but reinfected during pregnancy. Amid rising cases and stagnant resources, some states have focused disease investigations on pregnant women of childbearing age; they can no longer prioritize treating sexual partners who are also infected.

Eric McGrath, MD, a pediatric infectious disease specialist at Wayne State University, Detroit, said that he’d seen several newborns in recent years whose mothers had been treated for syphilis but then were re-exposed during pregnancy by partners who hadn’t been treated.

Treating a newborn baby for syphilis isn’t trivial. Penicillin carries little risk, but delivering it to a baby often involves a lumbar puncture and other painful procedures. And treatment typically means keeping the baby in the hospital for 10 days, interrupting an important time for family bonding.

Dr. McGrath has seen a couple of babies in his career who weren’t diagnosed or treated at birth and later came to him with full-blown syphilis complications, including full-body rashes and inflamed livers. It was an awful experience he doesn’t want to repeat. The preferred course, he said, is to spare the baby the ordeal and treat parents early in the pregnancy.

But in some places, providers aren’t routinely testing for syphilis. Although most states mandate testing at some point during pregnancy, as of last year just 14 required it for everyone in the third trimester. The CDC recommends third-trimester testing in areas with high rates of syphilis, a growing share of the United States.

After Arizona declared a statewide outbreak in 2018, state health officials wanted to know whether widespread testing in the third trimester could have prevented infections. Looking at 18 months of data, analysts found that nearly three-quarters of the more than 200 pregnant women diagnosed with syphilis in 2017 and the first half of 2018 got treatment. That left 57 babies born with syphilis, nine of whom died. The analysts estimated that a third of the infections could have been prevented with testing in the third trimester.

Based on the numbers they saw in those 18 months, officials estimated that screening all women on Medicaid in the third trimester would cost the state $113,300 annually, and that treating all cases of syphilis that screening would catch could be done for just $113. Factoring in the hospitalization costs for infected infants, the officials concluded the additional testing would save the state money.

And yet prevention money has been hard to come by. Taking inflation into account, CDC prevention funding for STDs has fallen 41% since 2003, according to an analysis by the National Coalition of STD Directors. That’s even as cases have risen, leaving public health departments saddled with more work and far less money.

Janine Waters, STD program manager for the state of New Mexico, has watched the unraveling. When Ms. Waters started her career more than 20 years ago, she and her colleagues followed up on every case of chlamydia, gonorrhea, and syphilis reported, not only making sure that people got treatment but also getting in touch with their sexual partners, with the aim of stopping the spread of infection. In a 2019 interview with Kaiser Health News, she said her team was struggling to keep up with syphilis alone, even as they registered with dread congenital syphilis cases surging in neighboring Texas and Arizona.

By 2020, New Mexico had the highest rate of congenital syphilis in the country.

The COVID-19 pandemic drained the remaining resources. Half of health departments across the country discontinued STD fieldwork altogether, diverting their resources to COVID. In California, which for years has struggled with high rates of congenital syphilis, three-quarters of local health departments dispatched more than half of their STD staffers to work on COVID.

As the pandemic ebbs – at least in the short term – many public health departments are turning their attention back to syphilis and other diseases. And they are doing it with reinforcements. Although the Biden administration’s proposed STD prevention budget for 2023 remains flat, the American Rescue Plan Act included $200 million to help health departments boost contact tracing and surveillance for covid and other infectious diseases. Many departments are funneling that money toward STDs.

The money is an infusion that state health officials say will make a difference. But when taking inflation into account, it essentially brings STD prevention funding back to what it was in 2003, said Stephanie Arnold Pang of the National Coalition of STD Directors. And the American Rescue Plan money doesn’t cover some aspects of STD prevention, including clinical services.

The coalition wants to revive dedicated STD clinics, where people can drop in for testing and treatment at little to no cost. Advocates say that would fill a void that has plagued treatment efforts since public clinics closed en masse in the wake of the 2008 recession.

Texas, battling its own pervasive outbreak, will use its share of American Rescue Plan money to fill 94 new positions focused on various aspects of STD prevention. Those hires will bolster a range of measures the state put in place before the pandemic, including an updated data system to track infections, review boards in major cities that examine what went wrong for every case of congenital syphilis, and a requirement that providers test for syphilis during the third trimester of pregnancy. The suite of interventions seems to be working, but it could be a while before cases go down, said Amy Carter, the state’s congenital syphilis coordinator.

“The growth didn’t happen overnight,” Ms. Carter said. “So our prevention efforts aren’t going to have a direct impact overnight either.”

Approximately 20% of sexually active high schoolers reported testing for a sexually transmitted infection in the previous year, based on data from 2,501 respondents to the 2019 national Youth Risk Behavior Survey.

Data suggest that half of all new STIs in the United States occur in youth aged 15-24 years, and that 25% of sexually active young women in the United States have an STI, wrote Nicole Liddon, PhD, of the Centers for Disease Control and Prevention, Atlanta, and colleagues.

Although organizations including the American Academy of Pediatrics and the U.S. Preventive Services Task Force recommend varying degrees of routine STI screening for adolescents, data on the prevalence of testing in this population are limited, the researchers said.

However, the addition in 2019 of a question on STI testing to the national Youth Risk Behavior Survey (YRBS) provided an opportunity to assess prevalence of STI testing, identify potential barriers, and increase screening rates, they wrote.

In a study published in Pediatrics, the researchers reviewed data from the 2019 national YRBS, an anonymous survey administered biannually to public and private high school students across the United States.

The study population included 2,501 individuals who reported sexual activity with at least one person during the 3 months prior to the survey.

Overall, 20.4% of the respondents reported being tested for an STI in the previous year, including significantly more females than males (26.1% vs. 13.7%).

The prevalence of testing among females was not significantly different according to race/ethnicity, sexual identity, or the sex of sexual contacts, but the prevalence increased with age; 12.6%, 22.8%, 28.5%, and 36.9% for females aged 15 years and younger, 16 years, 17 years, and 18 years, respectively.

Among males, no significant differences in STI testing were noted according to race/ethnicity, age, sexual identity, or sex of sexual contacts.

The researchers also analyzed prevalence of STI tested based on sexual behaviors. Among female students, the prevalence of STI testing was higher among those who reported the following behaviors, compared with those who did not: nonuse of condoms at last sexual intercourse (34.1% vs. 18.2%), substance use at last sexual intercourse (32.0% vs. 24.7%), and having four or more lifetime sex partners (31.9% vs. 24.7%).

Among male students, the prevalence of STI testing was higher among those who reported the following behaviors, compared with those who did not: sex before age 13 years (27.1% vs. 12.1%), having two or more recent sex partners (22.4% vs. 10.4%), having four or more lifetime sex partners (22.3% vs. 9.5%), and substance use at last sexual intercourse (19.2% vs. 12.1%).

The low prevalence of STI testing in teens has become more urgent in the wake of the coronavirus pandemic, the researchers wrote. “These prevalence estimates were derived before the possible profound impacts of the pandemic on adolescent sexual behavior and access to and use of health care services.”

Current guidelines allow health care providers the options for opt-out STI screening as a strategy to improve screening rates and testing; however, this option does not eliminate the need for conversations with adolescent patients about sexual activity, they emphasized.

The study findings were limited by several other factors including the inability to directly assess adherence to screening recommendations specifically, the inability to determine whether low testing rates resulted from limited access to health care or missed screening opportunities at visits, and the inclusion only of high school students but not out-of-school youth who may have more limited access to testing.

However, the results highlight the need to improve STI testing services for adolescents, and to address barriers at the individual and clinic level, they said. The addition of a question about past-year STI testing to the 2019 and future YRBS survey will promote ongoing monitoring of efforts to increase testing rates.

Teen sexual health goes beyond testing

The current study shows that routine testing for STIs according to published guidelines is low, Cynthia Holland-Hall, MD, and Andrea E. Bonny, MD, of Nationwide Children’s Hospital and Ohio State University, both in Columbus, wrote in an accompanying editorial.

Notably, sexually active females and males who had sex with male partners, two groups for whom annual testing is specifically recommended by multiple organizations, had testing rates of less than 30%, they said. The authors highlighted the study’s lack of information on which specific barriers, such as lack of access to the health care system, lack of knowledge, and fear of disclosure, contributed to overall low rates of testing.

However, STI testing is only one element of sexual and reproductive health care. Although opt-out testing may improve detection rates, the editorialists emphasized the need for patient-provider conversations about sex, citing recent studies showing that adolescents who spent some time alone with providers were more likely to receive sexual and reproductive health (SRH) services in the past year.

“Resources such as confidentiality policies, checklists, and written screening tools may facilitate SRH discussions,” Dr. Holland-Hall and Dr. Bonny said. “With a little practice, respect, and intention, a caring provider can take the awkward out of discussing sexual health but must not opt out of the conversation.”
 

Privacy and time issues exacerbate low testing rates

The current study is especially important at this time because many adolescents have likely missed well visits, and therefore important STI screens, because of disruptions caused by the COVID-19 pandemic, Karalyn Kinsella, MD, a pediatrician in private practice in Cheshire, Conn., said in an interview.

“I was surprised that the rate of screening was only one in five,” said Dr. Kinsella. “I knew it would be suboptimal, but not that low.”

According to Dr. Kinsella, there are two major barriers to increasing STI testing in adolescents in primary care. One barrier is that insurance companies will often state on the bill what the testing was for, which will lead to an uncomfortable conversation at a later date for the adolescent and parent when the bill arrives in the mail. A second barrier is when to test during a visit,. “If we obtain urine samples on all adolescents and many of them are not sexually active, we are wasting a lot of time in the short visit to obtain urine,” she explained. “If testing is scheduled for the end of the visit, they often leave without providing a urine sample.”

Overall, the study is an important reminder to general pediatricians about STI testing for sexually active teens, she emphasized. 

The study received no outside funding. The researchers had no financial conflicts to disclose. The editorialists had no financial conflicts to disclose. Dr. Kinsella had no financial conflicts to disclose and serves on the editorial advisory board of Pediatric News.

Approximately 20% of sexually active high schoolers reported testing for a sexually transmitted infection in the previous year, based on data from 2,501 respondents to the 2019 national Youth Risk Behavior Survey.

Data suggest that half of all new STIs in the United States occur in youth aged 15-24 years, and that 25% of sexually active young women in the United States have an STI, wrote Nicole Liddon, PhD, of the Centers for Disease Control and Prevention, Atlanta, and colleagues.

Although organizations including the American Academy of Pediatrics and the U.S. Preventive Services Task Force recommend varying degrees of routine STI screening for adolescents, data on the prevalence of testing in this population are limited, the researchers said.

However, the addition in 2019 of a question on STI testing to the national Youth Risk Behavior Survey (YRBS) provided an opportunity to assess prevalence of STI testing, identify potential barriers, and increase screening rates, they wrote.

In a study published in Pediatrics, the researchers reviewed data from the 2019 national YRBS, an anonymous survey administered biannually to public and private high school students across the United States.

The study population included 2,501 individuals who reported sexual activity with at least one person during the 3 months prior to the survey.

Overall, 20.4% of the respondents reported being tested for an STI in the previous year, including significantly more females than males (26.1% vs. 13.7%).

The prevalence of testing among females was not significantly different according to race/ethnicity, sexual identity, or the sex of sexual contacts, but the prevalence increased with age; 12.6%, 22.8%, 28.5%, and 36.9% for females aged 15 years and younger, 16 years, 17 years, and 18 years, respectively.

Among males, no significant differences in STI testing were noted according to race/ethnicity, age, sexual identity, or sex of sexual contacts.

The researchers also analyzed prevalence of STI tested based on sexual behaviors. Among female students, the prevalence of STI testing was higher among those who reported the following behaviors, compared with those who did not: nonuse of condoms at last sexual intercourse (34.1% vs. 18.2%), substance use at last sexual intercourse (32.0% vs. 24.7%), and having four or more lifetime sex partners (31.9% vs. 24.7%).

Among male students, the prevalence of STI testing was higher among those who reported the following behaviors, compared with those who did not: sex before age 13 years (27.1% vs. 12.1%), having two or more recent sex partners (22.4% vs. 10.4%), having four or more lifetime sex partners (22.3% vs. 9.5%), and substance use at last sexual intercourse (19.2% vs. 12.1%).

The low prevalence of STI testing in teens has become more urgent in the wake of the coronavirus pandemic, the researchers wrote. “These prevalence estimates were derived before the possible profound impacts of the pandemic on adolescent sexual behavior and access to and use of health care services.”

Current guidelines allow health care providers the options for opt-out STI screening as a strategy to improve screening rates and testing; however, this option does not eliminate the need for conversations with adolescent patients about sexual activity, they emphasized.

The study findings were limited by several other factors including the inability to directly assess adherence to screening recommendations specifically, the inability to determine whether low testing rates resulted from limited access to health care or missed screening opportunities at visits, and the inclusion only of high school students but not out-of-school youth who may have more limited access to testing.

However, the results highlight the need to improve STI testing services for adolescents, and to address barriers at the individual and clinic level, they said. The addition of a question about past-year STI testing to the 2019 and future YRBS survey will promote ongoing monitoring of efforts to increase testing rates.

Teen sexual health goes beyond testing

The current study shows that routine testing for STIs according to published guidelines is low, Cynthia Holland-Hall, MD, and Andrea E. Bonny, MD, of Nationwide Children’s Hospital and Ohio State University, both in Columbus, wrote in an accompanying editorial.

Notably, sexually active females and males who had sex with male partners, two groups for whom annual testing is specifically recommended by multiple organizations, had testing rates of less than 30%, they said. The authors highlighted the study’s lack of information on which specific barriers, such as lack of access to the health care system, lack of knowledge, and fear of disclosure, contributed to overall low rates of testing.

However, STI testing is only one element of sexual and reproductive health care. Although opt-out testing may improve detection rates, the editorialists emphasized the need for patient-provider conversations about sex, citing recent studies showing that adolescents who spent some time alone with providers were more likely to receive sexual and reproductive health (SRH) services in the past year.

“Resources such as confidentiality policies, checklists, and written screening tools may facilitate SRH discussions,” Dr. Holland-Hall and Dr. Bonny said. “With a little practice, respect, and intention, a caring provider can take the awkward out of discussing sexual health but must not opt out of the conversation.”
 

Privacy and time issues exacerbate low testing rates

The current study is especially important at this time because many adolescents have likely missed well visits, and therefore important STI screens, because of disruptions caused by the COVID-19 pandemic, Karalyn Kinsella, MD, a pediatrician in private practice in Cheshire, Conn., said in an interview.

“I was surprised that the rate of screening was only one in five,” said Dr. Kinsella. “I knew it would be suboptimal, but not that low.”

According to Dr. Kinsella, there are two major barriers to increasing STI testing in adolescents in primary care. One barrier is that insurance companies will often state on the bill what the testing was for, which will lead to an uncomfortable conversation at a later date for the adolescent and parent when the bill arrives in the mail.

A 64-year-old woman is evaluated for fever, diarrhea, and abdominal pain. She was diagnosed with Clostridioides difficile 2 months ago and completed a 10-day course of vancomycin. Her stool toxin test is positive for Clostridioides difficile (C. diff). Based on the most recent Infectious Diseases Society of America (IDSA) guidelines, what would be the preferred therapy?

A) Metronidazole

B) Fidaxomicin + bezlotoxumab

C) Vancomycin

D) Fecal microbiota transplant

The recommendations from the 2021 guidelines would be to treat with fidaxomicin and add bezlotoxumab.¹ The guidelines highlight the following changes:

• In patients with an initial Clostridioides difficile infections (CDI) fidaxomicin is preferred over vancomycin.
• In patients with a recurrent CDI episode, fidaxomicin is favored over vancomycin. For patients with multiple recurrences, vancomycin in a tapered and pulsed regimen, vancomycin followed by rifaximin, and fecal microbiota transplantation are options in addition to fidaxomicin.
• Addition of bezlotoxumab to standard of care antibiotics is recommended for recurrence of CDI within the first 6 months over standard of care antibiotics alone

The feasibility of these recommendations is up for debate. The cost of a course of fidaxomicin is $2,800, and the cost of bezlotoxumab is about $4,500. Cost effectiveness studies that helped drive the recommendations show a savings by reducing future hospitalizations for C. diff.² Unfortunately, this enthusiasm is not shared by many insurance companies for outpatient treatment.

Knee osteoarthritis

I will save you the excitement of the new acromegaly guidelines and focus on something we see all the time: knee osteoarthritis. The American Academy of Orthopedic Surgeons has released guidelines for this condition.³ The useful points I found were as follows:

• Topical application of nonsteroidal anti-inflammatory drugs (e.g., diclofenac) should be used to improve function and quality of life in patients with knee osteoarthritis.
• Exercise routines (i.e, supervised, unsupervised, and/or aquatic) are recommended versus no exercise for improving pain and function in patients with knee osteoarthritis.
• Not recommended is the use of oral narcotics (including tramadol), as they are not effective at improving pain or function, and their use results in a significant increased risk of adverse events.
• Not recommended for routine use in symptomatic knee osteoarthritis is intra-articular injection of hyaluronic acid.

I was happy to see topical NSAIDS recommended, as they are a much safer option in older patients than oral NSAIDS (which were also recommended). The recommendation against narcotics, including tramadol, is a shift from the recommendation of tramadol in the 2013 guidelines.⁴ Acetaminophen was enthusiastically recommended, and is still worth a try.

Sexually transmitted infections

• The dosing for the treatment of gonorrhea has increased to 500 mg of ceftriaxone (was 250 mg in 2015 guidelines), with a dose of 1 gram for patients who weigh more than 150 kg.
• Chlamydia infections should be treated with a 7-day course of doxycycline as the preferred antibiotic, except in pregnant women (where azithromycin is recommended).
• Herpes simplex virus 2 recurrences can be treated with twice-daily dosing of 800 mg of acyclovir for 5 days, or acyclovir 800 mg three times a day for 2 days. The shortest course for recurrence is famciclovir 1 gram twice a day for 1 day.
• The Centers for Disease Control and Prevention has removed the recommendation for avoidance of alcohol when taking metronidazole.

I hope these highlights of guidelines for common issues we see are helpful!

PHOENIX – A liquid biopsy test may accurately predict recurrence of human papillomavirus (HPV)–driven oropharyngeal squamous cell carcinoma (OPSCC) earlier than standard clinical and imaging assessments, a new analysis indicates.

Of 80 patients who tested positive for circulating tumor tissue–modified viral (TTMV)-HPV DNA during surveillance, 74% (n = 59) had no other evidence of disease or had indeterminate disease status.

And of those patients, 93% (n = 55) “later had proven recurrent, metastatic disease on imaging and/or biopsy,” according to Glenn Hanna, MD, from the Dana-Farber Cancer Institute, Boston, who presented the results Feb. 24 at the 2022 Multidisciplinary Head and Neck Cancers Symposium.

“This is the first study to demonstrate broad clinical utility and validity of the biomarker in HPV-driven oropharyngeal cancer,” Dr. Hanna said in a press release.

Although patients with HPV-driven OPSCC generally have favorable outcomes, up to 25% will experience recurrence after treatment.

Post-treatment surveillance currently relies on physical examinations and imaging, but Dr. Hanna and colleagues wanted to determine whether a routine circulating cell-free TTMV-HPV DNA test could detect occult recurrence sooner.

Dr. Hanna and colleagues analyzed the records of 1,076 patients with HPV-driven OPSCC at 118 sites in the U.S. who had completed therapy more than 3 months previously and undergone an TTMV-HPV DNA test (NavDx, Naveris) between June 2020 and November 2021.

The results of the test, which used ultrasensitive digital droplet PCR to identify HPV subtypes 16, 18, 31, 33, and 35, were compared with subsequent clinical evidence of OPSCC via nasopharyngolaryngoscopy, radiologic evaluations, or tissue biopsy.

Approximately 7% of the patients tested positive (n = 80) for circulating TTMV-HPV DNA. Of those, 26.2% (n = 21) had known clinical recurrence, while 73.8% (n = 59) had no other evidence of disease or an intermediate disease status.

Among those with no clinical evidence of recurrence, 93.2% (n = 55) had their recurrence subsequently confirmed using imaging or biopsy. Of the 4 remaining patients, 2 had clinically suspicious lesions, and 2 had no other evidence of disease.

Overall, the data indicate that the biomarker test demonstrated a 95% positive predictive value (76 of 80 patients) for recurrence or persistence of HPV-driven OPSCC.

According to Dr. Hanna, a positive TTMV-HPV DNA test was the first indicator of recurrence for 72% of patients, and almost half of recurrences were detected more than 12 months after completing therapy.

“Incorporating a test for TTMV-HPV DNA into routine post-treatment follow-up can enable physicians to detect recurrent cancers earlier and allow us to start recommended interventions more quickly to improve outcomes,” Dr. Hanna said in the release.

The study was supported by Naveris, which developed the TTMV-HPV DNA test studied. Dr. Hanna declares relationships with Actuate Therapeutics, Altor BioScience, Bicara, BMS, GSK, Merck, Regeneron, Sanofi/Genzyme, and others.

Approximately 7% of the patients tested positive (n = 80) for circulating TTMV-HPV DNA. Of those, 26.2% (n = 21) had known clinical recurrence, while 73.8% (n = 59) had no other evidence of disease or an intermediate disease status.

Among those with no clinical evidence of recurrence, 93.2% (n = 55) had their recurrence subsequently confirmed using imaging or biopsy. Of the 4 remaining patients, 2 had clinically suspicious lesions, and 2 had no other evidence of disease.

Overall, the data indicate that the biomarker test demonstrated a 95% positive predictive value (76 of 80 patients) for recurrence or persistence of HPV-driven OPSCC.

According to Dr. Hanna, a positive TTMV-HPV DNA test was the first indicator of recurrence for 72% of patients, and almost half of recurrences were detected more than 12 months after completing therapy.

“Incorporating a test for TTMV-HPV DNA into routine post-treatment follow-up can enable physicians to detect recurrent cancers earlier and allow us to start recommended interventions more quickly to improve outcomes,” Dr. Hanna said in the release.

The study was supported by Naveris, which developed the TTMV-HPV DNA test studied. Dr. Hanna declares relationships with Actuate Therapeutics, Altor BioScience, Bicara, BMS, GSK, Merck, Regeneron, Sanofi/Genzyme, and others.

PHOENIX – A liquid biopsy test may accurately predict recurrence of human papillomavirus (HPV)–driven oropharyngeal squamous cell carcinoma (OPSCC) earlier than standard clinical and imaging assessments, a new analysis indicates.

Of 80 patients who tested positive for circulating tumor tissue–modified viral (TTMV)-HPV DNA during surveillance, 74% (n = 59) had no other evidence of disease or had indeterminate disease status.

And of those patients, 93% (n = 55) “later had proven recurrent, metastatic disease on imaging and/or biopsy,” according to Glenn Hanna, MD, from the Dana-Farber Cancer Institute, Boston, who presented the results Feb. 24 at the 2022 Multidisciplinary Head and Neck Cancers Symposium.

“This is the first study to demonstrate broad clinical utility and validity of the biomarker in HPV-driven oropharyngeal cancer,” Dr. Hanna said in a press release.

Although patients with HPV-driven OPSCC generally have favorable outcomes, up to 25% will experience recurrence after treatment.

Post-treatment surveillance currently relies on physical examinations and imaging, but Dr. Hanna and colleagues wanted to determine whether a routine circulating cell-free TTMV-HPV DNA test could detect occult recurrence sooner.

Dr. Hanna and colleagues analyzed the records of 1,076 patients with HPV-driven OPSCC at 118 sites in the U.S. who had completed therapy more than 3 months previously and undergone an TTMV-HPV DNA test (NavDx, Naveris) between June 2020 and November 2021.

The Food and Drug Administration has approved secnidazole for the treatment of bacterial vaginosis (BV) and trichomoniasis in patients aged 12 years and older.

The antimicrobial agent, marketed as Solosec, was first approved in 2017 as a treatment for BV in adult women. In 2021, it was approved for the treatment of trichomoniasis in adult men and women.

Lupin Pharmaceuticals, which manufactures the drug, announced the expanded approval for adolescents in a news release.

The medication is meant to be taken as a single dose. It comes in a packet that should be sprinkled onto applesauce, yogurt, or pudding and consumed without chewing or crunching.

The treatment option may help “address gaps in care related to adherence,” said Tom Merriam, an executive director with Lupin.

Bacterial vaginosis is a common vaginal infection. Trichomoniasis is the most common nonviral, curable STI in the United States. Sexual partners of patients with trichomoniasis can be treated at the same time.

Vulvovaginal candidiasis is one of the possible side effects of secnidazole treatment, the drug’s label notes.
