In endometrial cancer and SUI, concomitant surgery improves outcomes
TUCSON, ARIZ. – according to a study examining the effects of an SUI screen among endometrial cancer patients.
An estimated 40%-80% of women with endometrial cancer experience SUI. The malignancy often is caught early enough to be treated with curative intent, and that is leading physicians and patients to think more about quality of life outcomes.
And yet, few patients receive concomitant surgery. Twenty percent of the women in the current study opted for concomitant surgeries, yet large database studies show the frequency of concomitant surgeries is about 2.5%. “There’s huge room for improvement in this area. The take-home message is that this is prevalent, this is doable, and this is something that could truly benefit this population,” Evelyn Hall, MD, said in an interview. Dr. Hall is a fellow in female pelvic medicine and reconstructive medicine at Brown University, Providence, R.I. She presented the study at the annual scientific meeting of the Society of Gynecologic Surgeons.
It’s not entirely surprising that SUI tends to be overlooked in patients with endometrial cancer. After all, they are going through a life-changing medical diagnosis, and oncologists are laser focused on achieving a cure when possible. But a bigger picture view, especially in light of the high cure rate for endometrial cancer when detected early, should encourage physicians to think differently about patient management.
The biggest trick may be incorporating concomitant surgeries into the surgical work flow. “It can be challenging logistically. It requires surgical planning and coordination between the two surgeons,” said Dr. Hall. But she said the experience at Brown University showed that it was possible with some patience. “It took a while to get the balls rolling, but once we figured out [it] worked for our institution, we’ve seen a continued uptake,” she said.
An important remaining question is the safety of the concomitant surgeries. Dr. Hall did not report any between-group differences in her presentation, but analysis is ongoing. They found a statistically significant increase in the number of readmissions among the concomitant surgery group, but most were deemed unlikely to be related to concomitant surgery.
In the study, 1,322 endometrial surgical candidates were screened for SUI, and 53% tested positive. Of these, 556 patients were offered concomitant surgical or nonsurgical SUI treatment: 21% chose concomitant surgery, 19% chose nonsurgical SUI treatment, and 60% of patients opted for no SUI treatment.
At 6 months after surgery, the concomitant surgery group was more likely to have a Urinary Distress Inventory (UDI)–Stress score of 0 than were those who were treated nonsurgically (odds ratio, 2.8; P = .0001) and those in the no-treatment group (OR, 3.7; P less than .0001). The concomitant group also was more likely to have a surgical site infection (SSI) score of 0 than was the nonsurgical group (OR, 2.9; P = .0008) and the no-treatment group (OR, 2.7; P less than .0001). Severe/very severe SSI scores occurred in 57% of the concomitant group at baseline, and this frequency dropped to 14% at 6 weeks (P less than .0001).
The study was funded by the Patient-Centered Outcomes Research Institute. Dr. Hall has no relevant financial disclosures.

Stress incontinence surgery improves sexual dysfunction
TUCSON, ARIZ. –
The finding comes from a secondary analysis of two randomized, controlled trials comparing Burch colposuspension, autologous fascial slings, retropubic midurethral polypropylene slings, and transobturator midurethral polypropylene slings. The analysis looked at outcomes at 24 months after surgery. Stephanie Glass Clark, MD, a resident at Virginia Commonwealth University, Richmond, presented the results at the annual scientific meeting of the Society of Gynecologic Surgeons.
In the secondary analysis of the Stress Incontinence Surgical Treatment Efficacy Trial (SISTEr) and the Trial of Midurethral Slings (TOMUS) trials, Dr. Clark and her fellow researchers looked at the effect of surgical failure on sexual dysfunction outcomes. Subjective failure was defined as self-reported SUI symptoms or self-reported leakage by 3-day voiding diary beyond 3 months after the surgery. Objective failure was defined as any treatment for SUI after the surgery or a positive stress test or pad test beyond 3 months after the surgery.
Participants were excluded from the two studies if they were sexually inactive in the previous 6 months at baseline, at 12 months post baseline, or at 24 months. The studies employed the short form of the Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire (PISQ-12), which had 12 questions with scores ranging from 0 to 4. The secondary analysis sample included 488 women from SISTEr and 436 women from TOMUS.
There were some baseline differences among groups between the two trials, including vaginal deliveries, race/ethnicity, stage of prolapse, and concomitant surgeries performed at time of the anti-incontinence procedure.
All four surgeries were associated with improvements in sexual function, with no statistically significant between-group differences. Mean PISQ-12 scores improved from a range of 31-33 to a range of 36-38 at 24 months. Although there is no published minimum important difference for PISQ-12 scores, an improvement of at least one-half of a standard deviation is generally accepted as clinically meaningful. “In this case, the standard deviation at baseline was just under 3 and so the improvement of each treatment group by more than 1.5 is a clinically meaningful improvement in their sexual function,” Dr. Clark said.
“Sexual dysfunction is a much more common problem than we previously thought, so we’ve been trying to figure out if patients with pelvic floor disorders like stress incontinence are going to have any improvement in sexual dysfunction by surgically treating their stress incontinence. Previously published data had been pretty conflicting,” Dr. Clark added in an interview.
That previous research was mostly retrospective and could have been impacted by patient selection bias. By analyzing clinical trials, the researchers hoped to test their idea that the pelvic floor symptoms themselves may be key to sexual dysfunction and that treating it surgically would improve matters.
The positive result is encouraging, but it still leaves unanswered questions about the mechanism behind the relationship. Dr. Clark wondered whether leaking urine leakage during sex might be the culprit, or whether it is fear or shame associated with the condition.
The answer may come from further analysis of women who were sexually inactive at baseline, but became sexually active over the course of the studies. “I think looking at that patient population in particular is going to be an interesting area of research. Is it that it was completely related to their pelvic floor disorder, and then we fixed it [so] they could have a more fulfilling sexual life?” speculated Dr. Clark.
The study received some funding from the National Institutes of Health. Dr. Clark reported no relevant financial disclosures.

Older women have good functional recovery after POP surgery
TUCSON, ARIZ. – according to a new study.
Functional status was defined as the ability to perform activities essential to self-care, independent living, and recreation.
Patients with the highest level of function at baseline actually had a slight decrease in functionality scores, although this difference was not clinically meaningful.
“We can tell patients: You’re high functioning, your prolapse is bothering you in other ways, but we’re going to keep you as high functioning as you are now. I think that’s really important for older women who are retired and want to stay active. They want to make sure they don’t have a surgery that’s going to make them less so,” Daniel Lee, MD, of the University of Pennsylvania, Philadelphia, said in an interview. Dr. Lee presented the study at the annual scientific meeting of the Society of Gynecologic Surgeons.
The study used data from multiple centers across the United States and a range of patient ethnicities. “That helped strengthen the conclusions,” Dr. Lee said. Most previous studies used generalized questionnaires rather than functional outcome questionnaires to determine patient outcomes.
One confounder is the potential presence of cognitive dysfunction, which can occur sometimes in older women following surgery. The study relied on surveys and excluded patients who weren’t able to understand them. Two patients were much worse after the surgery, and Dr. Lee speculated that cognitive dysfunction could have been the cause, although the team could not confirm that. “There’s a possibility that preexisting dementia or cognitive dysfunction could be unmasked by the surgery,” he said. The team is working to incorporate accelerometers to more objectively measure outcomes and will soon publish a feasibility study of their use in older women with cognitive dysfunction.
One limitation of the study was that it excluded women who were considered poor candidates for surgery. But that also suggests that patient selection is working as intended. “I think it just shows that surgeons do a very good job of figuring out who is a good surgical candidate, that they turn out to be better off [functionally] or that their prolapse gets improved,” Dr. Lee said.
The researchers analyzed questionnaire data from 176 women. The mean age was 72 years, and mean body mass index was 27 kg/m2; 87% of the women were Caucasian and 10% were black. Using the Activities Assessment Scale (AAS), which covers sedentary, ambulatory, and work/exercise domains, as well as the Patient Health Questionnaire to measure depression, the researchers found that, by 3 months, 59% of patients had an improved functional status, 35% had returned to within one standard deviation of baseline, and 6% had worsened, compared with their baseline scores.
Patients in the improved group started at a mean baseline total AAS score of 85 and improved to 100 at 3 months. Those who returned to baseline started at 100 on average and returned to 100 at 3 months, while those in the worsened group had a mean baseline score of 100 and a mean score of 93 at 3 months (P less than .001 for all comparisons).
The study was funded by the Fellows Pelvic Research Network. The investigators reported no relevant financial disclosures.

Alternative regimen reduces narcotic use after pelvic reconstructive surgery
TUCSON, ARIZ. – compared with a standard regimen, with no difference in patient satisfaction scores.
The new study extends findings from other surgical procedures to pelvic reconstructive surgery.
“This can limit both inpatient and outpatient narcotic use. It uses oral Toradol on an outpatient basis. It’s totally underutilized. People are afraid of it, people think it causes more bleeding, and maybe there’s a cost issue,” Andrey Petrikovets, MD, a urogynecologist in Los Angeles, said in an interview.
The regimen, which he calls ICE-T, relies in part on 16 tablets of Toradol sent home with the patient – 4 days’ worth. “It’s just 16 tablets, so it’s cheap, and patients do great with it. If you really use Toradol appropriately, especially on an outpatient basis, you can pretty much eliminate outpatient narcotic use,” said Dr. Petrikovets, who presented the work at the annual scientific meeting of the Society of Gynecologic Surgeons.
He believes that ICE-T is a good option for vaginal surgery. It’s a possibility for benign laparoscopic and perhaps robotic surgery, although those applications need to be studied. ICE-T should be avoided in patients with chronic pain, as well as patients with contraindications to any of the regimen’s medications, Dr. Petrikovets said.
According to the protocol, until hospital discharge, patients receive 20 minutes of ice to the perineum every 2 hours, 30 mg IV Toradol every 6 hours, 1,000 mg oral Tylenol every 6 hours, and 0.2 mg IV Dilaudid every 3 hours as needed for breakthrough pain. The constant pain management is important, said Dr. Petrikovets. “Patients don’t have an opportunity for the pain to get really high,” he said. At-home management includes 1,000 mg oral Tylenol every 6 hours, as needed (pain level 1-5, 60 tablets), and 10 mg Toradol every 6 hours as needed (pain level 6-10, 16 tablets).
The trial was conducted at two centers, where 63 patients were randomized to ICE-T or a standard regimen, which at the hospital included 600 mg ibuprofen every 6 hours as needed for pain levels 1-3, one tablet of Percocet (5/325 mg) every 4-6 hours as needed for pain levels 4-6, two tablets of Percocet for pain levels 7-10, and 0.2 mg IV Dilaudid every 3 hours as needed for breakthrough pain. At-home management consisted of 600 mg ibuprofen every 6 hours for pain levels 1-5 (60 tablets), and Percocet 5/325 mg every 6 hours for pain levels 6-10 (16 tablets).
Using the visual analog scale, researchers found that the 30 patients in the ICE-T arm of the study had less morning pain (VAS score, 20 mm vs. 40 mm; P = .03), and lower numerical pain score at 96 hours (2 vs. 3; P = .04). During the mornings and at 96 hours, the two groups had similar quality of recovery and satisfaction scores.
Narcotic use, measured as oral morphine equivalents, was significantly lower in the ICE-T arm between exit from the postanesthesia care unit (PACU) and hospital discharge (3 vs. 20; P less than .001) and through PACU all the way to discharge (17 vs. 38; P less than .001); 70% of patients in the ICE-T arm required no narcotics after PACU discharge, compared with 12% in the standard care arm (P less than .001).
At 96 hours, there was no significant difference between the two groups in the number of emergency department visits, percentage who had a bowel movement since surgery, or the number of Percocet/Toradol tablets taken. The ICE-T group took more Tylenol tablets than did the standard group took ibuprofen (11 vs. 6; P = .012).

The regimen, which he calls ICE-T, relies in part on 16 tablets of Toradol sent home with the patient – 4 days’ worth. “It’s just 16 tablets, so it’s cheap, and patients do great with it. If you really use Toradol appropriately, especially on an outpatient basis, you can pretty much eliminate outpatient narcotic use,” said Dr. Petrikovets, who presented the work at the annual scientific meeting of the Society of Gynecologic Surgeons.
He believes that ICE-T is a good option for vaginal surgery. It’s a possibility for benign laparoscopic and perhaps robotic surgery, although those applications need to be studied. ICE-T should be avoided in patients with chronic pain, as well as patients with contraindications to any of the regimen’s medications, Dr. Petrikovets said.
According to the protocol, until hospital discharge, patients receive 20 minutes of ice to the perineum every 2 hours, 30 mg IV Toradol every 6 hours, 1,000 mg oral Tylenol every 6 hours, and 0.2 mg IV Dilaudid every 3 hours as needed for breakthrough pain. The constant pain management is important, said Dr. Petrikovets. “Patients don’t have an opportunity for the pain to get really high,” he said. At-home management includes 1,000 mg oral Tylenol every 6 hours, as needed (pain level 1-5, 60 tablets), and 10 mg Toradol every 6 hours as needed (pain level 6-10, 16 tablets).
The trial was conducted at two centers, where 63 patients were randomized to ICE-T or a standard regimen, which at the hospital included 600 mg ibuprofen every 6 hours as needed for pain levels 1-3, one tablet of Percocet (5/325 mg) every 4-6 hours as needed for pain levels 4-6, two tablets of Percocet for pain levels 7-10, and 0.2 mg IV Dilaudid every 3 hours as needed for breakthrough pain. At-home management consisted of 600 mg ibuprofen every 6 hours for pain levels 1-5 (60 tablets), and Percocet 5/325 mg every 6 hours for pain levels 6-10 (16 tablets).
Using the visual analog scale, researchers found that the 30 patients in the ICE-T arm of the study had less morning pain (VAS score, 20 mm vs. 40 mm; P = .03), and lower numerical pain score at 96 hours (2 vs. 3; P = .04). During the mornings and at 96 hours, the two groups had similar quality of recovery and satisfaction scores.
Narcotic use, measured as oral morphine equivalents, was significantly lower in the ICE-T arm between exit from the postanesthesia care unit (PACU) and hospital discharge (3 vs. 20; P less than .001) and through PACU all the way to discharge (17 vs. 38; P less than .001); 70% of patients in the ICE-T arm required no narcotics after PACU discharge, compared with 12% in the standard care arm (P less than .001).
At 96 hours, there was no significant difference between the two groups in the number of emergency department visits, percentage who had a bowel movement since surgery, or the number of Percocet/Toradol tablets taken. The ICE-T group took more Tylenol tablets than did the standard group took ibuprofen (11 vs. 6; P = .012).

REPORTING FROM SGS 2019
Genetic data boost HIV surveillance efforts
SEATTLE – Advances in genetic sequencing are boosting efforts to identify new clusters of HIV infections and guiding public health interventions to address them. The method relies on resistance testing at diagnosis and virologic failure and allows public health researchers to determine the genetic relatedness of viruses responsible for new infections. If the viruses are genetically, geographically, and temporally associated, it indicates a previously unknown transmission cluster.
“The presence of a cluster indicates gaps in our preventative services, which we must address to improve service delivery and stop transmission,” Alexandra M. Oster, MD, Division of HIV/AIDS Prevention, Surveillance, and Epidemiology at the Centers for Disease Control and Prevention, Atlanta, said during a talk at the Conference on Retroviruses and Opportunistic Infections.
She noted that HIV brings special challenges to outbreak detection. The median delay between infection and diagnosis is 3 years. Individuals are highly mobile, and signals of new outbreaks can be quickly drowned out in high-burden areas. But these challenges aren’t unique. Tuberculosis has a similarly lengthy latency period, yet more than 75% of new TB outbreaks are now identified through the use of genetic data. Sequencing also is used to track food-borne illness. The CDC’s PulseNet is a network of laboratories that examines DNA sequences from bacterial infections in search of previously unrecognized outbreaks.
In the HIV setting, molecular surveillance has great potential in identifying and intervening in evolving networks of HIV transmission, but also carries ethical and other challenges.
Nevertheless, “I hope to make the case that cluster detection and response [using molecular surveillance] can help bring the nation closer to ending the HIV epidemic,” said Dr. Oster.
Molecular surveillance obtains most of its data from drug resistance testing, both at entry to care and after virologic failure, which then gets passed to the U.S. National HIV Surveillance System. The data are then stripped of patient identifying information and submitted to the CDC.
With data from multiple individuals in hand, researchers create a phylogenetic tree, in which closely-related viruses appear as close neighbors on a branch. “By tracing back along the tree, you can see the inferred ancestor of [individual strains], and also the inferred ancestor of all strains on the tree,” said Dr. Oster. Together with geographical data, that information allows researchers to identify clusters of patients connected in a transmission network, and that information can be passed along to federal, state, and local agencies to prevent infections and improve care.
From 1997 through 2012, the CDC’s molecular surveillance program focused on drug resistance patterns, but in 2013 the agency decided to expand to include transmission clusters. It now uses a tool called HIV Trace, which helps public health workers with no background in bioinformatics to visualize the DNA sequences and potential clusters, though Dr. Oster cautioned against overinterpretation of the results. “The links shown can easily be misinterpreted as actual social connections,” she said.
As proof of the approach’s potential, an analysis of the clusters identified showed their potential for HIV spread. On average in the United States, four new HIV infections occur per 100 people living with HIV. In the first 13 clusters that CDC identified, the number of infections was 33 per 100 person-years. The first 60 clusters had an average of 44 transmissions per 100 person-years. “None of these clusters had been found by [standard] epidemiologic methods, demonstrating that rapid transmission can be hard to detect without molecular data,” said Dr. Oster.
In 2018, all health departments began collecting sequencing data, and almost 40% of newly diagnosed patients have had sequencing data reported, more than 340,000 patients in total. Researchers have identified 145 priority clusters.
But use of molecular data is not the only method available. The CDC monitors increases in diagnoses in specific areas and conducts time-space analyses. These more traditional methods are particularly useful in areas with small populations or low HIV burden.
With a cluster identified, public health officials can attempt to identify all of the members of the network and help them to access services, such as testing, preexposure prophylaxis (PrEP), syringe service programs, and linkage to care.
In San Antonio, Tex., an analysis identified a cluster of 24 gay and bisexual men, and further analysis revealed an extended network of 87 sexual or needle-sharing partners. Researchers also identified missed opportunities for diagnosis of acute infection as well as low access to PrEP, so the health department sent out an alert clarifying diagnosis testing guidelines, highlighting the concern over acute infection, and containing PrEP educational material.
Analysis of another network in Michigan found that all identified individuals were virally suppressed, even though the network continued to grow. That suggested that there were unidentified individuals who were contributing to transmission, which prompted efforts by providers to encourage testing, linkage to care, and prevention.
All of these developments are good news for efforts to eradicate HIV, but they come with pitfalls. Local communities have expressed concerned that molecular data could be used to identify direction of transmission and for prosecution, since there are HIV laws that criminalize lack of disclosure and potential exposure to the virus, even when transmission doesn’t occur. “These laws are not aligned with current science and have not been found to help curb HIV,” said Dr. Oster.
She noted that current molecular methods are incapable of identifying direction of transmission. Still, the CDC is reemphasizing efforts to protect public health data from nonpublic health use. “CDC and health departments implement unprecedented policies and procedures to ensure confidentiality and security of the data,” Dr. Oster said.
She reported having no relevant disclosures.

EXPERT ANALYSIS FROM CROI 2019
STIs pose complex challenge to HIV efforts
SEATTLE – Sexually-transmitted infections (STIs) such as gonorrhea, chlamydia, and syphilis are on the rise among HIV-infected individuals, and emerging antimicrobial resistance in these organisms is presenting serious challenges to physicians. The issue may be traceable to the introduction of preexposure prophylaxis (PrEP) in 2011, which previous studies have shown to be associated with less condom use.
In the United States, a 2017 report by the Centers for Disease Control and Prevention showed rising incidences of chlamydia (+5% from 2015 to 2017), gonorrhea (+19%), and syphilis (+18%). “We have an incidence among men who have sex with men [MSM] that is above the pre-AIDS era estimates, and we have evidence of spread into heterosexual networks, and a very scary collision with the methamphetamine and heroine using networks,” said Jeanne Marrazzo, MD, professor of infectious diseases at the University of Alabama at Birmingham.
But the numbers alone don’t tell the whole story. “It’s not just the burden of these infections. What’s characterizing these trends is that we have continuing evolution of microbial resistance, which is really a crisis,” Dr. Marrazzo added during a plenary she delivered at the Conference on Retroviruses & Opportunistic Infections.
These infections also remain intricately linked with HIV. An analysis of syphilis cases found that 88% occurred in men. Of those, 80% were MSM. Of the cases in MSM, 46% were coinfected with HIV. “Those are incredible rates,” said Dr. Marrazzo. Among women, the trends are even more alarming. There has been a greater than 150% increase in primary/secondary and congenital syphilis between 2013 and 2017.
Resistance to ceftriaxone and azithromycin remains on the rise in gonorrhea, with 24% of countries reporting at least a 5% incidence of strains that are less susceptible or resistant to ceftriaxone, and 81% of countries reporting similar trends with azithromycin.
In the absence of new drugs to overcome that resistance, or vaccines that can prevent gonorrhea and other infections, what are clinicians to do?
One option may be postexposure doxycycline. One trial in MSM showed that a 200-mg dose taken 24-72 hours after sex was associated with about a 70% increase in both time to first chlamydia and time to first syphilis infection, though no effect was seen on gonorrhea infections. “We shouldn’t be surprised. We know that gonorrhea is classically resistant to tetracyclines, and the MSM population has the highest prevalence of antimicrobial resistance in gonorrhea,” said Dr. Marrazzo.
There are pros and cons to this strategy, of course. On the one hand, doxycycline works for chlamydia and syphilis, it’s safe, and it’s easy to administer. “We’re up a tree when it comes to syphilis, so why not?” opined Dr. Marrazzo. In fact, some MSM have read the literature and are already using it prophylactically. But there are downsides, including adverse effects such as esophagitis/ulceration and photosensitivity, and it is contraindicated in pregnant women. And then there’s the potential for evolving greater resistance. “The horse is out of the barn with respect to gonorrhea, but I think it’s worth thinking about resistance to other pathogens, where we still rely on doxycycline [to treat] in rare cases,” said Dr. Marrazzo.
Finally, Dr. Marrazzo discussed the role of STI treatment in the effort to eradicate HIV. Should the Getting to 0 strategies include aggressive prevention and treatment of STIs? Despite the potentiating role of some STIs in the spread HIV, some urban areas are approaching zero new infections even as other STIs remain a problem. It could be that undetectable = untransmittable, regardless of the presence an STI. Some view targeting STIs as a regressive practice in a setting where the U=U mantra has opened up an era of sexual freedom living with or at risk of HIV.
On the other hand, there are also good arguments to target STIs while trying to eliminate HIV. Results from high-resource locales such as San Francisco and New York City are unlikely to be replicated in places like Sub-Saharan Africa. The public health burden of STIs is extensive, and antibiotic resistance and antibiotic shortages can make treatment difficult. The situation is also different for women, who may experience impacts on fertility or pregnancies, and do not have the same freedom as men in many countries. “Stigma is highly operative and I would wager that sexual pleasure and freedom remain a very elusive goal for women across the globe,” said Dr. Marrazzo.
Dr. Marrazzo has a research grant/grant pending from Cepheid, and is on the advisory panels of BioFire and Gilead.

Resistance to ceftriaxone and azithromycin remains on the rise in gonorrhea, with 24% of countries reporting at least a 5% incidence of strains that are less susceptible or resistant to ceftriaxone, and 81% of countries reporting similar trends with azithromycin.
In the absence of new drugs to overcome that resistance, or vaccines that can prevent gonorrhea and other infections, what are clinicians to do?
One option may be postexposure doxycycline. One trial in MSM showed that a 200-mg dose taken 24-72 hours after sex was associated with about a 70% increase in both time to first chlamydia and time to first syphilis infection, though no effect was seen on gonorrhea infections. “We shouldn’t be surprised. We know that gonorrhea is classically resistant to tetracyclines, and the MSM population has the highest prevalence of antimicrobial resistance in gonorrhea,” said Dr. Marrazzo.
There are pros and cons to this strategy, of course. On the one hand, doxycycline works for chlamydia and syphilis, it’s safe, and it’s easy to administer. “We’re up a tree when it comes to syphilis, so why not?” opined Dr. Marrazzo. In fact, some MSM have read the literature and are already using it prophylactically. But there are downsides, including adverse effects such as esophagitis/ulceration and photosensitivity, and it is contraindicated in pregnant women. And then there’s the potential for evolving greater resistance. “The horse is out of the barn with respect to gonorrhea, but I think it’s worth thinking about resistance to other pathogens, where we still rely on doxycycline [to treat] in rare cases,” said Dr. Marrazzo.
Finally, Dr. Marrazzo discussed the role of STI treatment in the effort to eradicate HIV. Should the Getting to 0 strategies include aggressive prevention and treatment of STIs? Despite the potentiating role of some STIs in the spread HIV, some urban areas are approaching zero new infections even as other STIs remain a problem. It could be that undetectable = untransmittable, regardless of the presence an STI. Some view targeting STIs as a regressive practice in a setting where the U=U mantra has opened up an era of sexual freedom living with or at risk of HIV.
On the other hand, there are also good arguments to target STIs while trying to eliminate HIV. Results from high-resource locales such as San Francisco and New York City are unlikely to be replicated in places like Sub-Saharan Africa. The public health burden of STIs is extensive, and antibiotic resistance and antibiotic shortages can make treatment difficult. The situation is also different for women, who may experience impacts on fertility or pregnancies, and do not have the same freedom as men in many countries. “Stigma is highly operative and I would wager that sexual pleasure and freedom remain a very elusive goal for women across the globe,” said Dr. Marrazzo.
Dr. Marrazzo has a research grant/grant pending from Cepheid, and is on the advisory panels of BioFire and Gilead.
EXPERT ANALYSIS FROM CROI 2019
Following pelvic floor surgery, patients value functional goals
TUCSON, ARIZ. – according to results of a new study. Such negative reactions occur more frequently as time passes and may be related to incongruent patient expectations, which may in turn affect physician-patient communication.
“We must bridge the gap between expectations and the occurrence of an unanticipated problem. What this study highlights is a need for counseling beyond the traditional complications, and more discussion about the possibility of failure in terms of the things that the patients identify as important,” Brenna McGuire, MD, a resident at the University of New Mexico, Albuquerque, said while presenting the results at the annual scientific meeting of the Society of Gynecologic Surgeons.
The work highlights the need to look at outcomes in a different way, said Vivian Sung, MD, who was not involved in the research and was a discussant following the presentation. “Most of our studies are designed with methodology to emphasize efficacy and often secondary outcomes to capture complications and adverse events. But there is a gray area. It’s something that’s evolving, and we’re getting better at,” Dr. Sung, professor of obstetrics and gynecology at Brown University and a urogynecologist at Women and Infants Hospital, both in Providence, R.I., said in an interview.
The success of a procedure is typically evaluated by determining incontinence during an office visit, but the problem may not be occurring at that particular moment, and the patient may not be happy with the overall outcome. “Sometimes you can fix one problem, and the other problems become more prominent, or new problems develop. [Incontinence alone is] not a perfect picture or what the patient was envisioning her outcome to be,” Dr. Sung said.
Expectations can potentially be better managed through better patient counseling, but that’s not a simple fix either, she noted. Most surgeons counsel patients on negative outcomes, but adverse events with a 5%-10% probability may fail to make an impression. “Really, the rate is zero or 100%. It’s not that it doesn’t seem like a meaningful complication, it’s just that it doesn’t seem like it will happen to you. And then when it does, it can be very devastating depending on what it is and what your expectation was.”
Dr. McGuire and her associates followed 20 women (mean age, 55 years; 50% non-Hispanic white, 25% Hispanic, 25% Native American) at a single institution in New Mexico who underwent surgeries for pelvic floor disorders. They interviewed each participant before and after surgery, at 4-6 weeks, and 6 months after surgery, asking them to rank adverse events at each time point.
Before surgery, patients expressed concerns about postoperative pain, injury, and catheter issues. At 6-8 weeks, the chief concerns were daily activities, sexual activity, and symptom reduction. At 6 months, incontinence, sexual dysfunction, and mental health issues predominated. In other words, concerns migrated from traditional complications to functional outcomes over time.
At the 6-8 week interview, a representative quote was: “It’s the fact that it didn’t work. It’s the fact that I’m still suffering from all the same symptoms.” At 6 months, another quote was: “I hate this so much. It really does impact my life negatively. It affects my work, it affects everything, and makes me very angry.”
Traditional adverse events such as pain and infection dropped in frequency between the preoperative interview and the 6-month interview from 7.5%-10.0% to 2.5%-5.0% by 6 months. However, functional outcomes were a different matter: Concerns about a failed surgery increased from 10% to 25%, sexual dysfunction from 4% to 8%, and effect on daily function from 4% to 11%.
The study was funded by the University of New Mexico. Dr. McGuire and Dr. Sung reported no relevant financial disclosures.

Long-acting injectables noninferior to tablet integrase for HIV
SEATTLE – A long-acting, injectable combination of the novel integrase inhibitor cabotegravir (CAB) and the second-generation nonnucleoside reverse transcriptase inhibitor rilpivirine (RPV) was noninferior to dolutegravir/abacavir/lamivudine (DTG/ABC/3TC) in one phase 3 study (FLAIR) and to three-drug oral antiretroviral therapy (ART) more broadly in the companion ATLAS phase 3 study. Patient acceptance of the injectable formulation was surprisingly high, although researchers admitted there was likely some selection bias because patients already interested in receiving an injection would have been predisposed to entering the trials.
Still, the numbers were impressive: 99% of patients who received the intramuscular injection expressed more satisfaction with it than with their previous oral regimen in the FLAIR study, and 98% expressed a similar opinion in the ATLAS study. Circumstantial evidence also suggests there may be some demand, according to Joseph Eron, MD, professor of medicine at the University of North Carolina at Chapel Hill, who commented during a press conference at the Conference on Retroviruses & Opportunistic Infections. “These studies didn’t take a long time to accrue. People were very interested, so it wasn’t as if people had to go around and beat the bushes to try to find people [to participate],” said Dr. Eron, who was not an author on either report.
“My patients tell me that they like not having to worry about taking their pills every day. There may be some relief from the stigma of HIV. You don’t have to think about it,” Susan Swindells, MBBS, medical director of the Specialty Care Clinic at the University of Nebraska Medical Center in Omaha and first author of the ATLAS trial, said during the press conference.
There were some injection site reactions, but they were generally mild and most resolved within 7 days. In the ATLAS study, 75% of participants reported injection site pain, and 1% discontinued as a result. In the FLAIR study, 82% in the CAB/RPV arm experienced an injection site reaction, with a median duration of 3 days; 99% of reactions were grade 1 or 2.
Should the combination achieve regulatory approval, it remains to be seen how challenging it will be to manage patients with monthly injections and ensure they stick to the schedule. The injections must be administered by a health care provider.
“In terms of generalizability outside of the study, it would be a paradigm shift in our therapy,” Chloe Orkin, MBBCh, said at a press conference. Dr. Orkin is the first author on the FLAIR trial report and a consultant in HIV Medicine at Barts Health National Health Service Trust. She pointed to the example of injectable contraception. “It can be done. It’s just that we haven’t done it. It will require some thought,” Dr. Orkin added.
In the ATLAS study, 616 participants taking two nucleoside reverse transcriptase inhibitor (NRTIs) and an integrase inhibitor, a non-NRTI, or a protease inhibitor, were randomized 1:1 to continue their regimen (CART arm) or switch to CAB/RPV, following a 4-week safety monitoring period of oral CAB/RPV. After 48 weeks, 1.6% in the CAB/RPV arm and 1.0% in the CART arm had HIV-1 RNA greater than or equal to 50 copies/mL, which met the prespecified noninferiority margin. Of patients in the CAB/RPV arm, 93% had HIV-1 RNA less than 50 copies/mL at week 48 versus 95% in the CART arm, and the difference was not statistically significant. Grade 3 or 4 events were seen in 11% of CAB/RPV and 7% of CART patients.
The FLAIR study randomized 566 ART-naive patients to receive either CAB/RPV or DTG/ABC/3TC after a 20-week induction phase, followed by a 4-week safety monitoring period for those going into the CAB/RPV arm. At week 48, 2.1% in the CAB/RPV arm and 2.5% in the DTG/ABC/3TC arm had HIV-1 RNA greater than or equal to 50 copies/mL, which met the prespecified noninferiority margin, while 94% in the CAB/RPV arm and 93% in the DTG/ABC/3TC arm had HIV-1 RNA less than 50 copies/mL. Confirmed virologic failure occurred in four patients (1.4%) in the CAB/RPV arm, and three of those patients had mutations in the NNRTI+INSTI domains, while the fourth patient was not tested. Three failures occurred in the DTG/ABC/3TC arm, and none of those patients had INSTI resistance mutations. A total of 82% of CAB/RPV patients had injection site reactions, 99% of which were grade 1 or 2, and the median duration was 3 days.
The ATLAS and FLAIR studies were sponsored by ViiV. Janssen and GlaxoSmithKline were collaborators.

CAC score over 1,000 carries higher risks
, based on data from a large retrospective study presented by Allison W. Peng at the annual meeting of the American College of Cardiology.
“Our data argues for consideration of CAC 1000 (or more) as a distinct group with CVD mortality greater than that of contemporary secondary prevention trials ... We showed that those with CAC 1000 (or more) have both a higher area and density of calcification, a more dispersed pattern of calcification in their coronary artery tree (the majority with 4-vessel disease), with a markedly more diffuse distribution of extra-coronary calcification compared to the other CAC groups,” Ms. Peng and her colleagues wrote in the study, which was published online in the Journal of the American College of Cardiology.
Future guidelines should address these patients as a distinct risk group that might gain the most benefit from targeted, aggressive preventive therapy, the researchers said.
Current guidelines identify individuals with CAC scores over 400 as the highest risk group. With a mean follow-up time of 12.3 years, the results from 66,636 asymptomatic individuals in the CAC consortium study, which included over 2,800 patients with CAC (Agatston) scores of 1,000 or more, indicate patients with CAC scores of 1000 or more have nearly a 2-fold higher risk of CVD mortality compared to those with CAC scores of 400-999. While the mortality risk levels off slightly in those with scores exceeding 1000, all-cause and cause-specific mortality risk still increases with no apparent upper CAC threshold.
Patients with a CAC score of at least 1000 were 66.3 years old, on average; 86.3% were male, 52.4% had 4-vessel CAC, and they had a larger total CAC area.
Compared to patients with CAC scores of 400-999, those with a CAC score of 1000 or more had a greater risk of cardiovascular disease (HR, 1.71; 95% CI, 1.41-2.08), coronary heart disease (HR, 1.84; 95% CI, 1.43-2.36), cancer (HR, 1.36; 95% CI, 1.07-1.73), and all-cause mortality (HR, 1.51; 95% CI, 1.33-1.70).
Those with CAC scores of 400-999 had a 2.1, 3.6, 2.7, and 9.8 mortality rate per 1000 person-years for CHD, CVD, cancer, and all-cause mortality, respectively. But those with CAC scores of 1000 of more had a 5.1, 8.0, 4.6, and 18.8 mortality rate per 1000 person-years for CHD, CVD, cancer, and all-cause mortality, respectively.
The leading cause of death was CVD; 36.5% in the CAC 400-999 group and 42.6% in the CAC 1000 or more group. CHD mortality, as a subset of CVD mortality, constituted 21.1% of deaths in the CAC 400-999 group and 27.1% of deaths in the CAC 1000 or more group.
“Future randomized controlled trials of aggressive preventative therapies, for example PCSK9-inhibitors and anti-inflammatory drugs, in patients with CAC ≥ 1000, may prove helpful to evaluate the benefits of such treatment in this unique group,” the authors wrote. They also urged updating current guidelines to reflect best practices for these patients.
The study was funded by The National Institutes of Health. The authors have no relevant financial disclosures.

We showed that those with CAC 1000 (or more) have both a higher area and density of calcification, a more dispersed pattern of calcification in their coronary artery tree (the majority with 4-vessel disease), with a markedly more diffuse distribution of extra-coronary calcification compared to the other CAC groups,” Ms. Peng and her colleagues wrote in the study, which was published online in the Journal of the American College of Cardiology.
Future guidelines should address these patients as a distinct risk group that might gain the most benefit from targeted, aggressive preventive therapy, the researchers said.
Current guidelines identify individuals with CAC scores over 400 as the highest risk group. With a mean follow-up time of 12.3 years, the results from 66,636 asymptomatic individuals in the CAC consortium study, which included over 2,800 patients with CAC (Agatston) scores of 1,000 or more, indicate patients with CAC scores of 1000 or more have nearly a 2-fold higher risk of CVD mortality compared to those with CAC scores of 400-999. While the mortality risk levels off slightly in those with scores exceeding 1000, all-cause and cause-specific mortality risk still increases with no apparent upper CAC threshold.
Patients with a CAC score of at least 1000 were 66.3 years old, on average; 86.3% were male, 52.4% had 4-vessel CAC, and they had a larger total CAC area.
Compared to patients with CAC scores of 400-999, those with a CAC score of 1000 or more had a greater risk of cardiovascular disease (HR, 1.71; 95% CI, 1.41-2.08), coronary heart disease (HR, 1.84; 95% CI, 1.43-2.36), cancer (HR, 1.36; 95% CI, 1.07-1.73), and all-cause mortality (HR, 1.51; 95% CI, 1.33-1.70).
Those with CAC scores of 400-999 had a 2.1, 3.6, 2.7, and 9.8 mortality rate per 1000 person-years for CHD, CVD, cancer, and all-cause mortality, respectively. But those with CAC scores of 1000 of more had a 5.1, 8.0, 4.6, and 18.8 mortality rate per 1000 person-years for CHD, CVD, cancer, and all-cause mortality, respectively.
The leading cause of death was CVD; 36.5% in the CAC 400-999 group and 42.6% in the CAC 1000 or more group. CHD mortality, as a subset of CVD mortality, constituted 21.1% of deaths in the CAC 400-999 group and 27.1% of deaths in the CAC 1000 or more group.
“Future randomized controlled trials of aggressive preventative therapies, for example PCSK9-inhibitors and anti-inflammatory drugs, in patients with CAC ≥ 1000, may prove helpful to evaluate the benefits of such treatment in this unique group,” the authors wrote. They also urged updating current guidelines to reflect best practices for these patients.

Repeat VTE risk heightened in HIV patients
SEATTLE – HIV infection is associated with increased risk of recurrent venous thromboembolism, especially within 1 year of the initial episode. The finding, presented during a poster session at the Conference on Retroviruses & Opportunistic Infections, follows up on an earlier study that found that first-time VTE risk also is higher among HIV-positive individuals than in the general population.
The conclusion about first-time VTE risk, published earlier this year in Lancet HIV, came from a comparison between the ATHENA (AIDS Therapy Evaluation in the Netherlands) cohort and European population-level of studies of VTE. It found a crude incidence of 2.33 VTE events per 1,000 person-years In HIV patients, with heightened odds when CD4 cell counts were below 200 cells/mcL (adjusted hazard ratio, 3.40).
The new work represents a follow-up and compared results from ATHENA (153 patients with HIV and first VTE) and the Dutch MEGA cohort (4,005 patients without HIV, with first VTE), which includes the general population. Overall, 26% of patients in the ATHENA cohort experienced a second VTE event, compared with 16% of the general population. At 1 year after anticoagulation withdrawal, HIV-positive individuals were at 67% increased risk (HR, 1.67). At 6-years after withdrawal, the relationship was not statistically significant (HR, 1.22).
Researchers also found that CD4 cell-count recovery was associated with lowered risk, with every 100 cell-count increase between initial VTE diagnosis and anticoagulant withdrawal linked to a 20% reduction in risk (HR, 0.80).
“The clinical question is: If it’s true you have an increased risk of recurrence, should you be continuing anticoagulant therapy longer in people with HIV? This poster doesn’t answer that question and you probably need a randomized, controlled trial to look at that,” Peter Reiss, MD, professor of medicine at Amsterdam University Medical Center, said in an interview during the conference.
In the absence of a clear answer, it’s sensible for clinicians to be aware of the potential increased risk, much as clinicians have internalized the increased risk of atherosclerotic vascular disease in HIV patients. “I think the publication [in Lancet HIV] as well as this poster suggest that on the venous side of things there may also be an accentuated risk,” said Dr. Reiss.
Heidi Crane, MD, a professor of medicine at the University of Washington, Seattle, presented a poster examining the underlying factors that may predispose HIV patients to first-time VTE events. Her team performed an adjudicated review of VTE cases among HIV patients at six institutions and found that the risk factors appeared to be distinct from those seen in the general population.
The traditional long plane ride was less common in this population, while factors such as injected drug use and pneumonia were more common. The VTE events occurred at a median age of 49 years; 30% of the patients had a detectable viral load. “We’re seeing a little more (VTE) than you might expect, and in a younger population than you might have guessed,” said Dr. Crane in an interview.
The most frequent predisposing risk factors were recent hospitalization (40%), infection (40%), or immobilization/bed rest (24%) within the past 90 days, and injectable drug use (22%). “It’s not just the traditional risk factors. Some HIV-specific risk factors are driving this,” said Dr. Crane.
She also aims to learn more about the specifics of risk factors, such as catheter-associated thromboses. The team is working to increase the sample size in order to parse out the relationships with specific outcomes.
In the meantime, the data further characterize the health challenges facing people living with HIV. “This is another example demonstrating that comorbid conditions among patients with HIV that are often considered age related occur at much younger ages in our population,” said Dr. Crane.
