Gynecology

TOPLINE:

Virtual visits for urinary tract infections (UTIs) increased by more than 600% from 2015 to 2022, with overall UTI encounters growing by 325.9%. The rate of antibiotic dispensation climbed by 227.3% per 1000 patients, outpacing the 159.8% increase in positive urine cultures.

METHODOLOGY:

• Researchers conducted a retrospective cohort study analyzing 1,220,698 UTI encounters among 428,855 nonpregnant women aged ≥ 18 years at Kaiser Permanente Southern California from 2015 to 2022.
• Analysis included outpatient UTI encounters in ambulatory and urgent care settings, excluding emergency and inpatient visits.
• Data collection encompassed demographic information, urine tests, antibiotic dispensation, and UTI diagnoses using International Classification of Diseases, 9th and 10th Revision codes.
• Encounters conducted by physicians, physician assistants, nurse practitioners, and registered nurses through in-person, phone, video, and health portal platforms were evaluated.

TAKEAWAY:

• Virtual encounters grew by 603.2% compared with a 122.8% increase for in-person visits, with virtual visits accounting for 60% (733,263) of all UTI encounters.
• The rate of UTI encounters per 1000 adult female patients increased by 241.6%, while membership in the health system grew by only 24.4%.
• Antibiotics were prescribed without urine testing in 42.5% (519,135) of encounters, and among encounters with both antibiotic dispensation and urine testing, 57.1% (278,903) had a positive culture.
• According to the authors, the increasing rate of antibiotic dispensation surpassed the growth in positive urine culture rates, suggesting increased use of empiric antibiotics.

IN PRACTICE:

“Our findings underscore the importance of balancing telemedicine’s accessibility with maintaining antibiotic stewardship and highlight the need for updated guidelines,” wrote the authors of the study. An accompanying editorial said, “Unfortunately, our misguided conceptual model has led to several decades of UTI research focusing on bad bugs rather than investigating the natural host defenses, how we might boost these, what perturbs the ecosystem, and how microbial defense occurs within the bladder.”

LOS ANGELES — The majority of women with epilepsy are inadequately educated about the potential risks associated with anti-seizure medications (ASMs), which include teratogenicity and a reduction in the efficacy of hormonal birth control, early results of a new survey suggested.

In addition, only about a third of survey respondents indicated that they were taking folic acid if pregnant or planning to be or using an effective contraceptive if they wanted to avoid pregnancy.

“Physicians should see it as inside their scope to ask about the family planning aspect of things because it’s relevant to their patients’ neurologic care,” first study author Tori Valachovic, a fourth-year medical student at the University of Rochester School of Medicine, New York, told this news organization.

She noted patients may be taking ASMs not just for seizures but potentially to manage migraines or a mood disorder.

The findings were presented on December 8 at the American Epilepsy Society (AES) 78th Annual Meeting 2024.

 

Unique Survey

Research shows that about half of pregnancies in the United States are unplanned, and the number is even higher among people with epilepsy, said senior author Sarah Betstadt, MD, associate professor of obstetrics and gynecology, University of Rochester. That may be because women aren’t appropriately counseled about ASMs, possibly reducing the effectiveness of their hormonal birth control, she said.

The American Academy of Neurology recommends women with seizure disorders who could become pregnant receive yearly counseling about reproductive health, including ASM teratogenicity and interactions with hormonal contraceptive medications.

The study included 107 women aged 18-49 years at two general neurology outpatient clinics who were taking an ASM and completed a survey between July 2023 and May 2024. Of these, six were pregnant or planning to become pregnant, and 69 were using a barrier, hormonal, or implant form of contraception.

Researchers collected medical histories for each respondent, including how long they had had a seizure disorder, how often they experienced seizures, what anti-seizure drugs they were taking, the type of birth control they used, their pregnancy intentions, and whether they were taking folic acid.

The survey was unique in that questions were personalized. Previous surveys have asked general questions, but for the current survey, patients were required to input their specific ASM and specific birth control, so it was also a test of their knowledge of their specific medications, said Valachovic.

When responding to questions about the safety of their ASMs for pregnancy or whether there were interactions between ASMs and birth control, about two thirds (67.3%) of the participants answered at least one question incorrectly.

The study found 36.2% of those using a barrier, hormonal, or implant contraceptive answered at least one question incorrectly regarding whether their ASM decreased birth control effectiveness.

ASMs such as carbamazepine, phenytoin, phenobarbital, higher doses of topiramate (over 200 mg daily), and oxcarbazepine can make hormonal contraceptives such as pills, patches, and rings less effective, noted Valachovic.

There’s also a bidirectional relationship at play, she added. Hormonal contraceptives can make ASMs such as lamotrigine, valproate, zonisamide, and rufinamide less effective because they decrease the levels of the ASMs.

For questions specifically about the teratogenicity of their medications, about 56.1% of participants did not answer correctly.

ASMs that increase the risk for birth defects include valproic acid (a drug that would be at the top of the list), topiramate, carbamazepine, phenobarbital, and phenytoin, said Valachovic.

However, she added, “It’s a little bit more nuanced” than simply saying, “Don’t take this medication during pregnancy” because the first aim is to control seizures. “Uncontrolled seizures are more dangerous for the fetus and the expectant mother than any ASM,” she explained.

Neurologists and reproductive healthcare providers should work together to better disseminate relevant information to their female patients who could become pregnant, said Betstadt. “We need to have better ways to collaborate. And I think we have to start with educating neurologists,” who care for these women throughout their journey with epilepsy and who during that time may become pregnant.

They “should be talking to their patients annually about whether they plan to be pregnant,” so they can educate them and make them aware of dangers to the fetus with certain medications and the effect of ASMs on birth control, added Betstadt, whose practice focuses on complex family planning.

“Our hope is that patients will have better care that’s in line with their reproductive goals,” she said.

 

No Trickle-Down Effect

Commenting for this news organization, Alison M. Pack, MD, professor of neurology and Epilepsy Division Chief, Columbia University, New York City, said the study underlines an important quandary: Despite guidelines on risks of combining ASMs and hormonal birth control, this information doesn’t seem to be “trickling down” to women with epilepsy.

“I think part of it is just the state of healthcare delivery these days,” where clinicians are expected to accomplish more and more within a 20-30–minute follow-up visit. It’s tough, too, to keep up with all the potential drug interactions involved with newer ASMs, she said.

“I also think it speaks to the complexity” of healthcare for young women with epilepsy, which involves not just neurologists but obstetricians, gynecologists, and primary care doctors, she added.

Pack doesn’t think epilepsy specialists “integrate” enough with these other specialties. “You need to communicate with the gynecologist; you need to open that line of communication.”

She believes advanced practice providers could play a role in reducing the complexity of treating young women with epilepsy by regularly reviewing how patients are adhering to recommended protocols.

But she pointed out that “in the overall picture, most women with epilepsy do have normal, healthy pregnancies.”

The investigators and Pack reported no relevant conflicts of interest.

Patients with BRCA mutations and a history of early-onset breast cancer benefited from risk-reducing surgeries, according to new data presented at the San Antonio Breast Cancer Symposium (SABCS) 2024.

Having a risk-reducing mastectomy or salpingo-oophorectomy was associated with significantly improved overall survival and disease-free survival in BRCA-mutation carriers who had been diagnosed with a first breast cancer at age ≤ 40 years.

“This global study provides the first evidence that risk-reducing surgeries improve survival outcomes among young BRCA-mutation carriers with a prior history of early-onset breast cancer,” study investigator Matteo Lambertini, MD, PhD, oncologist with the University of Genova–IRCCS Policlinico San Martino Hospital in Genoa, Italy, said in a statement from the SABCS, where he presented the findings. “Considering the unique traits and needs of this younger population, and their high risk for secondary malignancies, it is critical to understand how risk-reducing surgeries affect patient outcomes, so that the risks and benefits of these procedures can be carefully weighed.”

“We hope these findings may help to improve the counseling on cancer-risk management strategies for BRCA carriers with young-onset of breast cancer below the age of 40 years,” Lambertini added during a press briefing. 

Various risk-reducing strategies, including risk-reducing surgeries, are recommended for BRCA-mutation carriers without a prior history of cancer, but the impact of these surgeries among younger populations with a history of early-onset breast cancer has been less clear.

The new findings come from the BRCA BCY Collaboration, an international, multicenter, retrospective cohort study of 5290 patients with likely pathogenic/pathogenic germline BRCA1 and/or BRCA2 mutations who were diagnosed with stages I-III breast cancer at ≤ 40 years. The risk-reducing mastectomy analysis included 2910 patients (55%) who underwent the surgery less than 1 year from diagnosis and 2380 who opted not to have the surgery. 

Primary endpoint was overall survival, and disease-free survival and breast cancer-free interval were secondary endpoints. Overall survival models were adjusted for the development of distant recurrences or second primary malignancies.

During median follow-up of 5.1 years, patients who underwent risk-reducing mastectomy had a 35% lower risk of dying (adjusted hazard ratio [aHR], 0.65) as well as a significant improvement in both disease-free survival (aHR, 0.58) and breast cancer-free interval (aHR, 0.55). The improved outcomes were seen in both BRCA1 and BRCA2 carriers, Lambertini reported. 

The risk-reducing salpingo-oophorectomy analysis included 2782 patients who underwent this surgery a median of 3 years from diagnosis and 2508 who did not. 

During median follow up of 4.9 years, risk-reducing salpingo-oophorectomy was associated with a 42% lower risk for death (aHR, 0.58) as well as an improvement in both disease-free survival (aHR, 0.68) and breast cancer-free interval (aHR, 0.65).

For risk-reducing salpingo-oophorectomy, there was an interaction based on breast cancer subtype and BRCA mutation.

“Specifically, the benefit of risk-reducing salpingo-oophorectomy was greater for patients with BRCA1 pathogenic variants and for those with triple-negative disease, as compared to those with BRCA2 pathogenic variants or luminal disease,” Lambertini reported.

Overall survival results were similar in patients who underwent one or both surgeries.

Briefing moderator Kate Lathrop, MD, with the University of Texas Health Science Center at San Antonio, noted that this study provides valuable information for counseling younger patients. Having datasets like this helps us give patients “potentially our best estimate of the amount of reduction of risk you could have by having the surgery now.”

In an interview, Freya Schnabel, MD, director of breast surgery at NYU Langone Health’s Perlmutter Cancer Center, New York City, emphasized the importance of early, well-informed decision-making upfront at the time of diagnosis in this patient population.

The benefit of “risk-reducing oophorectomy cannot be overemphasized, even in the presence of a known breast cancer because, as my colleagues and I say — we don’t want to cure their breast cancer and then have them die of ovarian cancer,” said Schnabel, who was not involved in the study.

In terms of prophylactic contralateral mastectomy, Schnabel noted that BRCA-mutation carriers have a “very high” risk for a second primary breast cancer. In her experience, “that’s what drives patients frequently at the time of diagnosis to have bilateral mastectomy because who wants to go through this more than once?” 

This is especially true for BRCA1 carriers who have a higher risk for triple-negative breast cancer, which is associated with a worse prognosis and is harder to treat, Schnabel said. 

“For these patients, having surgery prevents the patient from getting into a situation where their second primary tumor winds up being biologically more aggressive and then affects their survival,” Schnabel said.

The study was supported by the Italian Association for Cancer Research and the European Society for Medical Oncology. Lambertini reported advisory roles for Roche, Lilly, Novartis, AstraZeneca, Pfizer, Seagen, Gilead, MSD, Exact Sciences, Pierre Fabre, and Menarini. Lathrop consults for TeraSera Pharmaceuticals. Schnabel had no relevant disclosures.

The risk-reducing salpingo-oophorectomy analysis included 2782 patients who underwent this surgery a median of 3 years from diagnosis and 2508 who did not. 

During median follow up of 4.9 years, risk-reducing salpingo-oophorectomy was associated with a 42% lower risk for death (aHR, 0.58) as well as an improvement in both disease-free survival (aHR, 0.68) and breast cancer-free interval (aHR, 0.65).

For risk-reducing salpingo-oophorectomy, there was an interaction based on breast cancer subtype and BRCA mutation.

“Specifically, the benefit of risk-reducing salpingo-oophorectomy was greater for patients with BRCA1 pathogenic variants and for those with triple-negative disease, as compared to those with BRCA2 pathogenic variants or luminal disease,” Lambertini reported.

Overall survival results were similar in patients who underwent one or both surgeries.

Briefing moderator Kate Lathrop, MD, with the University of Texas Health Science Center at San Antonio, noted that this study provides valuable information for counseling younger patients. Having datasets like this helps us give patients “potentially our best estimate of the amount of reduction of risk you could have by having the surgery now.”

In an interview, Freya Schnabel, MD, director of breast surgery at NYU Langone Health’s Perlmutter Cancer Center, New York City, emphasized the importance of early, well-informed decision-making upfront at the time of diagnosis in this patient population.

The benefit of “risk-reducing oophorectomy cannot be overemphasized, even in the presence of a known breast cancer because, as my colleagues and I say — we don’t want to cure their breast cancer and then have them die of ovarian cancer,” said Schnabel, who was not involved in the study.

In terms of prophylactic contralateral mastectomy, Schnabel noted that BRCA-mutation carriers have a “very high” risk for a second primary breast cancer. In her experience, “that’s what drives patients frequently at the time of diagnosis to have bilateral mastectomy because who wants to go through this more than once?” 

This is especially true for BRCA1 carriers who have a higher risk for triple-negative breast cancer, which is associated with a worse prognosis and is harder to treat, Schnabel said. 

“For these patients, having surgery prevents the patient from getting into a situation where their second primary tumor winds up being biologically more aggressive and then affects their survival,” Schnabel said.

The study was supported by the Italian Association for Cancer Research and the European Society for Medical Oncology. Lambertini reported advisory roles for Roche, Lilly, Novartis, AstraZeneca, Pfizer, Seagen, Gilead, MSD, Exact Sciences, Pierre Fabre, and Menarini. Lathrop consults for TeraSera Pharmaceuticals. Schnabel had no relevant disclosures.

Patients with BRCA mutations and a history of early-onset breast cancer benefited from risk-reducing surgeries, according to new data presented at the San Antonio Breast Cancer Symposium (SABCS) 2024.

Having a risk-reducing mastectomy or salpingo-oophorectomy was associated with significantly improved overall survival and disease-free survival in BRCA-mutation carriers who had been diagnosed with a first breast cancer at age ≤ 40 years.

“This global study provides the first evidence that risk-reducing surgeries improve survival outcomes among young BRCA-mutation carriers with a prior history of early-onset breast cancer,” study investigator Matteo Lambertini, MD, PhD, oncologist with the University of Genova–IRCCS Policlinico San Martino Hospital in Genoa, Italy, said in a statement from the SABCS, where he presented the findings. “Considering the unique traits and needs of this younger population, and their high risk for secondary malignancies, it is critical to understand how risk-reducing surgeries affect patient outcomes, so that the risks and benefits of these procedures can be carefully weighed.”

“We hope these findings may help to improve the counseling on cancer-risk management strategies for BRCA carriers with young-onset of breast cancer below the age of 40 years,” Lambertini added during a press briefing. 

Various risk-reducing strategies, including risk-reducing surgeries, are recommended for BRCA-mutation carriers without a prior history of cancer, but the impact of these surgeries among younger populations with a history of early-onset breast cancer has been less clear.

The new findings come from the BRCA BCY Collaboration, an international, multicenter, retrospective cohort study of 5290 patients with likely pathogenic/pathogenic germline BRCA1 and/or BRCA2 mutations who were diagnosed with stages I-III breast cancer at ≤ 40 years. The risk-reducing mastectomy analysis included 2910 patients (55%) who underwent the surgery less than 1 year from diagnosis and 2380 who opted not to have the surgery. 

Primary endpoint was overall survival, and disease-free survival and breast cancer-free interval were secondary endpoints. Overall survival models were adjusted for the development of distant recurrences or second primary malignancies.

During median follow-up of 5.1 years, patients who underwent risk-reducing mastectomy had a 35% lower risk of dying (adjusted hazard ratio [aHR], 0.65) as well as a significant improvement in both disease-free survival (aHR, 0.58) and breast cancer-free interval (aHR, 0.55). The improved outcomes were seen in both BRCA1 and BRCA2 carriers, Lambertini reported. 

The risk-reducing salpingo-oophorectomy analysis included 2782 patients who underwent this surgery a median of 3 years from diagnosis and 2508 who did not. 

During median follow up of 4.9 years, risk-reducing salpingo-oophorectomy was associated with a 42% lower risk for death (aHR, 0.58) as well as an improvement in both disease-free survival (aHR, 0.68) and breast cancer-free interval (aHR, 0.65).

Antimicrobial resistance (AMR) is globally recognized as one of the greatest health threats of the 21st century, responsible for 1.27 million deaths annually. “According to the WHO, if no measures are taken promptly, AMR could lead to more deaths than cancer by 2050,” Arnaud Marchant, MD, PhD, director of the European Plotkin Institute for Vaccinology at Université libre de Bruxelles (EPIV-ULB), Anderlecht, Belgium, said in an interview with MediQuality, part of the Medscape Professional Network. “This is a huge problem, and vaccination could be part of the solution.”

EPIV-ULB marked the start of the World AMR Awareness Week (November 18-24) with an event highlighting the critical role of vaccination to counter the rise for resistant pathogens. During the event, MediQuality interviewed Marchant, along with several other experts in the field.

 

Antibiotics Losing Effectiveness

Marc Van Ranst, PhD, virologist at Rega Institute KU Leuven in Leuven, Belgium, echoed Marchant’s concerns. He noted that “an increasing number of bacteria are becoming resistant to more antibiotics.” “While antibiotics were once miracle drugs, they have now stopped — or almost stopped — working against certain bacteria. Although we are discovering more effective therapies, bacterial infections are increasingly likely to worsen due to AMR.”

Van Ranst issued a stark warning: “If this trend continues, it is entirely reasonable to predict that in 25 years, some antibiotics will become useless, certain bacterial infections will be much harder to treat, and deaths will outnumber those caused by cancer. It’s worth noting, however, that as cancer treatments improve, cancer-related deaths are expected to decline, further highlighting the growing burden of AMR-related fatalities.”

 

Viruses, Vaccines, and Resistance

Van Ranst emphasized that while AMR primarily involves bacteria, viral infections and vaccination against them also play a role in addressing the issue. “When vaccines prevent illness, they reduce the need for unnecessary antibiotic use. In the past, antibiotics were frequently prescribed for respiratory infections — typically caused by viruses — leading to misuse and heightened resistance. By preventing viral infections through vaccines, we reduce inappropriate antibiotic prescriptions and, subsequently, AMR.”

 

Strategic Areas of Focus

To maximize the impact of vaccination in combating AMR, Belgium must prioritize several strategic areas, according to EPIV-ULB. “Expanding vaccination coverage for recommended vaccines is crucial to effectively preventing the spread of resistant pathogens,” said Marchant.

“Innovation and development of new vaccines are also essential, including targeted research into vaccines for infections that are currently unavoidable through other means. Enhancing epidemiological surveillance through national data collection and analysis will further clarify the impact of vaccines on AMR and inform policy decisions.”

EPIV-ULB underscored the importance of educating the public and healthcare professionals. “Public awareness is essential to addressing vaccine hesitancy by providing clear information on the importance of prevention,” Marchant explained. “Healthcare professional training must also improve, encouraging preventive practices and judicious antibiotic use. Furthermore, additional research is necessary to fill data gaps and develop predictive models that can guide vaccine development in the future.”

 

Role of Vaccination

According to EPIV-ULB, Belgium needs a strengthened national strategy to address AMR effectively. “Complementary solutions are increasingly important as antimicrobials lose efficacy and treatments become more complex,” Marchant said. “Vaccination offers a proactive and effective preventive solution, directly and indirectly reducing the spread of resistant pathogens.”

Vaccines combat AMR through various mechanisms. “They prevent diseases such as pneumococcal pneumonia and meningitis, reducing the need for antibiotics to treat these infections,” Marchant explained. “Additionally, vaccination lowers inappropriate antibiotic use by preventing viral infections, reducing the risk of overprescribing antibiotics in cases where they are unnecessary. Lastly, herd immunity from vaccination slows the circulation of resistant pathogens, limiting their spread.”

Van Ranst urged healthcare professionals to prioritize vaccinating at-risk populations as identified by Belgium’s Superior Health Council. These include the elderly with underlying conditions and pregnant women, especially for influenza vaccines. University Hospitals Leuven in Belgium, also conducts annual vaccination campaigns for its staff, combining flu and COVID vaccines to increase uptake.

 

A Global Challenge

Marc Noppen, MD, PhD, director of University Hospital Brussels, Belgium, emphasized the complexity of AMR as a global issue. “The problem isn’t solely due to human antibiotic use; it also stems from veterinary medicine, plant breeding, and animal husbandry. This is a multifactorial, worldwide issue that requires public awareness. Improved vaccination strategies are one way to address AMR, particularly in this post-COVID era of heightened skepticism toward vaccines,” he explained.

Marie-Lise Verschelden from Pfizer highlighted the need for cooperation across the healthcare sector. “Belgium is fortunate to have a fantastic ecosystem of academics, clinicians, and industry experts. Collaboration, including government involvement, is critical to advancing our efforts. At Pfizer, we continue to develop new vaccines and technologies, and the COVID crisis has reinforced the critical role of vaccination in combating AMR. Through our vaccine portfolio and ongoing developments, we are well-positioned to contribute significantly to this global challenge.”

Elisabeth Van Damme from GSK reiterated that AMR is a global issue requiring joint efforts. “Existing vaccines are underutilized. Vaccination protects against certain infectious diseases, reducing the need for antibiotics. Antibiotics, in turn, are sometimes prescribed incorrectly, especially for viral infections they cannot treat. At GSK, we are already developing new vaccines to meet future needs.”

Vaccination remains a cornerstone in the fight against AMR. As pathogens grow increasingly resistant to antibiotics, coordinated efforts and innovative vaccine development are essential to mitigating this global health crisis.

Sarah Cigna, MD, sees patients every week with vulvovaginal pain and vulvar dermatoses. She’s an ob.gyn. with a focus on sexual health — often the first physician seen by patients with vulvar pain or itch — and she believes collaboration with dermatologists is essential, especially for complex cases in what she calls a neglected, data-poor area of medicine.

She also recommends that dermatologists have a good understanding of the vestibule, “one of the most important structures in vulvar medicine,” and that they become equipped to recognize generalized and localized causes of vulvar pain and/or itch.

“The problem is, we don’t talk about [vulvovaginal pain and itch] ... it’s taboo and we’re not taught about it in medical school,” Cigna, assistant professor of obstetrics and gynecology at The George Washington University (GWU), Washington, DC, said in a grand rounds lecture held recently at the GWU School of Medicine and Health Sciences Department of Dermatology.

“There are dermatologists who don’t have much training in vulvar dermatology, and a lot of gyns don’t get as much training” as they should, she said in an interview after the lecture. “So who’s looking at people’s vulvar skin and figuring out what’s going on and giving them effective treatments and evidence-based education?”

Cigna and dermatologist Emily Murphy, MD, will be co-directors of a joint ob.gyn-dermatology Vulvar Dermatology Clinic at GWU that will be launched in 2025, with monthly clinics for particularly challenging cases where the etiology is unclear or treatment is ineffective. “We want to collaborate in a more systematic way and put our heads together and think creatively about what will improve patient care,” Cigna said in the interview.

Dermatologists have valuable expertise in the immunology and genetic factors involved in skin disorders, Cigna said. Moreover, Murphy, assistant professor of dermatology and director of the Vulvar Health Program at GWU, said in an interview, dermatologists “are comfortable in going to off-label systemic medications that ob.gyns may not use that often” and bring to the table expertise in various types of procedures.

Murphy recently trained with Melissa Mauskar, MD, associate of dermatology and obstetrics and gynecology at the University of Texas Southwestern, Dallas, and founder and director of the Gynecologic Dermatology Clinic there. “It’s so important for dermatologists to be involved. It just takes some extra training that residents aren’t getting right now,” said Murphy, a member of the newly formed Vulvar Dermatoses Research Consortium.

In her grand rounds lecture, Cigna offered pearls to dermatologists for approaching a history and exam and covered highlights of the diagnosis and treatment of various problems, from vulvar Candida infections and lichen simplex chronicus to vulvar lichen sclerosus (LS), vulvar lichen planus (LP), vulvar Crohn’s disease, pudendal neuralgia, and pelvic floor muscle spasm, as well as the role of mast cell proliferation in vulvar issues.

 

Approaching the History and Exam

A comprehensive history covers the start, duration, and location of pain and/or itching as well as a detailed timeline (such as timing of potential causes, including injuries or births) and symptoms (such as burning, cutting, aching, and stinging). The question of whether pain “is on the outside, at the entrance, or deeper inside” is “crucial, especially for those in dermatology,” Cigna emphasized.

“And if you’re seeing a patient for a vulvar condition, please ask them about sex. Ask, is this affecting your sexual or intimate life with your partner because this can also give you a clue about what’s going on and how you can help them,” she told the audience of dermatologists.

Queries about trauma history (physical and emotional/verbal), competitive sports (such as daily cycling, equestrian, and heavy weight lifting), endometriosis/gynecologic surgery, connective tissue disorders (such as Ehler-Danlos syndrome), and irritable bowel syndrome are all potentially important to consider. It is important to ask about anxiety, depression, and obsessive-compulsive disorder, which do not cause — but are highly associated with — vulvar dermatoses, she said.

A surprisingly large number of people with vulvovaginal issues are being diagnosed with Ehler-Danlos syndrome, so “I’m always asking, are you hypermobile because this might be affecting the musculoskeletal system, which might be affecting the pelvis,” Cigna said. “Anything that affects the pelvis can affect the vulva as well.”

The pelvic examination should be “offered” rather than assumed to be part of the exam, as part of a trauma-informed approach that is crucial for earning trust, she advised. “Just saying, ‘we’re going to talk, and then I can offer you an exam if you like’…patients like it. It helps them feel safer and more open.”

Many diagnoses are differentiated by eliciting pain on the anterior vs the posterior half of the vulvar vestibule — the part of the vulva that lies between the labia minora and is composed of nonkeratinized tissue with embryonic origins in the endoderm. “If you touch on the keratinized skin (of the vulva) and they don’t have pain, but on the vestibule they do have pain, and there is no pain inside the vagina, this suggests there is a vestibular problem,” said Cigna.

Pain/tenderness isolated to the posterior half of the vestibule suggests a muscular cause, and pain in both the posterior and anterior parts of the vestibule suggests a cause that is more systemic or diffuse, which could be a result of a hormonal issue such as one related to oral contraceptives or decreased testosterone, or a nerve-related process.

Cigna uses gentle swipes of a Q-tip moistened with water or gel to examine the vulva rather than a poke or touch, with the exception being the posterior vestibule, which overlies muscle insertion sites. “Make sure to get a baseline in remote areas such as the inner thigh, and always distinguish between ‘scratchy/sensitive’ sensations and pain,” she said, noting the value of having the patient hold a mirror on her inner thigh.

 

Causes of Vulvar Itch: Infectious and Noninfectious

With vulvar candidiasis, a common infectious cause of vulvar itch, “you have to ask if they’re also itching on the inside because if you treat them with a topical and you don’t treat the vaginal yeast infection that may be co-occurring, they’ll keep reseeding their vulvar skin,” Cigna said, “and it will never be fully treated.”

Candida albicans is the most common cause of vulvar or vulvovaginal candidiasis, and resistance to antifungals has been rising. Non-albicans Candida “tends to have even higher resistance rates,” she said. Ordering a sensitivity panel along with the culture is helpful, but “comprehensive vaginal biome” panels are generally not useful. “It’s hard to correlate the information clinically,” she said, “and there’s not always a lot of information about susceptibilities, which is what I really like to know.”

Cigna’s treatments for vaginal infections include miconazole, terconazole, and fluconazole (and occasionally, itraconazole or voriconazole — a “decision we don’t take lightly”). Vulvar treatments include nystatin ointment, clotrimazole cream, and miconazole cream. Often, optimal treatment involves addressing “both inside and out,” she said, noting the importance of also killing yeast in undergarment fabric.

“In my experience, Diflucan [oral fluconazole] doesn’t treat persistent vulvar cutaneous skin yeast well, so while I might try Diflucan, I typically use something topical as well,” she said. “And with vaginal yeast, we do use boric acid from time to time, especially for non-albicans species because it tends to be a little more effective.”

Noninfectious causes of vulvar itch include allergic, neuropathic, and muscular causes, as well as autoimmune dermatoses and mast cell activation syndrome. Well known in dermatology are acute contact dermatitis and lichen simplex chronicus — both characterized by induration, thickening, and a “puffy” erythematous appearance, and worsening of pruritus at night. What may be less appreciated is the long list of implicated allergens , including Always menstrual pads made of a plastic-containing “dry weave” material, Cigna said. There are at least several cotton-only, low-preservative feminine products available on the market, she noted.

 

Common Autoimmune Vulvar Dermatoses: LS and LP

Vulvar LS has traditionally been thought to affect mainly prepubertal and postmenopausal women, but the autoimmune condition is now known to affect more reproductive-age people with vulvas than previously appreciated, Cigna said.

And notably, in an observational web-based study of premenopausal women (aged 18-50 years) with biopsy-confirmed vulvar LS, the leading symptom was not itch but dyspareunia and tearing with intercourse. This means “we’re missing people,” said Cigna, an author of the study. “We think the reason we’re not seeing itch as commonly in this population is that itch is likely mediated by the low estrogen state of pre- and postmenopausal people.”

Vulvar LS also occurs in pregnancy, with symptoms that are either stable or decrease during pregnancy and increase in the postpartum period, as demonstrated in a recently published online survey.

Patients with vulvar LS can present with hypopigmentation, lichenification, and scarring and architectural changes, the latter of which can involve clitoral phimosis, labial resorption, and narrowing of the introitus. (The vaginal mucosa is unaffected.) The presentation can be subtle, especially in premenopausal women, and differentiation between LS, vitiligo, and yeast is sometimes necessary.

A timely biopsy-driven definitive diagnosis is important because vulvar LS increases the risk for cancer if it’s not adequately treated and because long-term steroid use can affect the accuracy of pathology reports. “We really care about keeping this disease in remission as much as possible,” Cigna said. Experts in the field recommend long-term maintenance therapy with a mid-ultra-potent steroid one to three times/week or an alternative. “I’ve just started using ruxolitinib cream, a Janus kinase (JAK) inhibitor, and tacrolimus, a calcineurin inhibitor,” she said.

With vulvar LP, based on current evidence, the risk for malignant transformation is low, but “it crosses into the vagina and can cause vaginal adhesions, so if you’re diagnosing someone with lichen planus, you need to make sure you’re talking with them about dilators, and if you’re not comfortable, send them to [gyn],” she said.

The use of vulvoscopy is important for one’s ability to see the fine Wickham’s striae that often characterize vulvar LP, she noted. Medical treatments for vulvar LP include topical calcineurin inhibitors, high-potency steroids, and JAK inhibitors.

Surgical treatment of vulvar granuloma fissuratum caused by vulvar LS is possible (when the patient is in complete remission, to prevent koebnerization), with daily post-op application of clobetasol and retraction of tissues, noted Cigna, the author of a study on vulvar lysis of adhesions.

With both LS and LP, Cigna said, “don’t forget (consideration of) hormones” as an adjunctive treatment, especially in postmenopausal women. “Patients in a low hormone state will have more flares.”

 

Vulvar Crohn’s

“We all have to know how to look for this,” Cigna said. “Unilateral or asymmetric swelling is classic, but don’t rule out the diagnosis if you see symmetric swelling.” Patients also typically have linear “knife-like” fissures or ulcerations, the vulva “is very indurated,” and “swelling is so intense, the patients are miserable,” she said.

Vulvar Crohn’s disease may precede intestinal disease in 20%-30% of patients, so referral to a gastroenterologist — and ideally subsequent collaboration — is important, as vulvar manifestations are treated with systemic medications typical for Crohn’s.

A biopsy is required for diagnosis, and the pathologist should be advised to look for lichenified squamous mucosa with the Touton giant cell reaction. “Vulvar Crohn’s is a rare enough disorder that if you don’t have an experienced or informed pathologist looking at your specimen, they may miss it because they won’t be looking for it,” Cigna added in the interview. “You should be really clear about what you’re looking for.”

 

Neuropathic Itch, Pelvic Floor Muscle Spasm

Patients with pudendal neuralgia — caused by an injured, entrapped, or irritated pudendal nerve (originating from S2-S4) — typically present with chronic vulvar and pelvic pain that is often unprovoked and worsens with sitting. Itching upon touch is often another symptom, and some patients describe a foreign body sensation. The cause is often trauma (such as an accident or childbirth-related) as opposed to myofascial irritation, Cigna explained in her lecture.

“Your exam will be largely normal, with no skin findings, so patients will get sent away if you don’t know to look for pudendal neuralgia by pressing on the pudendal nerve or doing (or referring for) a diagnostic nerve block,” Cigna added in the interview.

Persistent genital arousal disorder (PGAD) is “more global” in that it can also originate not only from the pudendal nerve but also from nerve roots higher in the spine or even from the brain. “People feel a sense of arousal, but some describe it as an itch,” Cigna said in her lecture, referring to a 2021 consensus document on PGAD/genito-pelvic dysesthesia by the International Society for the Study of Women’s Sexual Health as a valuable resource for understanding and managing the condition.

Diagnosis and treatment usually start with a pudendal nerve block with a combination of steroid and anesthetic. If this does not relieve arousal/itching, the next step may be an MRI to look higher in the spine.

 

Pelvic Floor Muscle Spasm

Vulvar pain, skin itching, and irritation can be symptoms of pelvic floor muscle spasm. “Oftentimes people come to me and say, ‘I have a dermatologic problem,’” Cigna said. “The skin may look red and erythematous, but it’s probably more likely a muscle problem when you’re not finding anything, and no amount of steroid will help the itch go away when the problem lies underneath.”

Co-occurring symptoms can include vaginal dryness, clitoral pain, urethral discomfort, bladder pain/irritation, increased urgency, constipation, and anal fissures. The first-line treatment approach is pelvic floor therapy.

“Pelvic floor therapy is not just for incontinence. It’s also for pain and discomfort from muscles,” she said, noting that most patients with vulvar disorders are referred for pelvic floor therapy. “Almost all of them end up having pelvic floor dysfunction because the pelvic floor muscles spasm whenever there’s pain or inflammation.”

 

A Cautionary Word on Vulvodynia, and a Mast Cell Paradigm to Explore

Vulvodynia is defined as persistent pain of at least 3 months’ duration with no clear cause. “These are the patients with no skin findings,” Cigna said. But in most cases, she said, careful investigation identifies causes that are musculoskeletal, hormonal, or nerve-related.

“It’s a term that’s thrown around a lot — it’s kind of a catchall. Yet it should be a small minority of patients who truly have a diagnosis of vulvodynia,” she said.

In the early stages of investigation is the idea that mast cell proliferation and mast cell activation may play a role in some cases of vulvar and vestibular pain and itching. “We see that some patients with vulvodynia and vestibulodynia have mast cells that are increased in number in the epithelium and beneath the epithelium, and nerve staining shows an increased number of nerve endings traveling into the epithelium,” Cigna said.

“We do diagnose some people clinically” based on urticaria and other symptoms suggestive of mast cell proliferation/activation (such as flushing, abdominal cramping, diarrhea, hypotensive syncope or near syncope, and tachycardia), and “then we send them to the allergist for testing,” Cigna said.

Cigna and Murphy have no relevant financial disclosures.

Sarah Cigna, MD, sees patients every week with vulvovaginal pain and vulvar dermatoses. She’s an ob.gyn. with a focus on sexual health — often the first physician seen by patients with vulvar pain or itch — and she believes collaboration with dermatologists is essential, especially for complex cases in what she calls a neglected, data-poor area of medicine.

She also recommends that dermatologists have a good understanding of the vestibule, “one of the most important structures in vulvar medicine,” and that they become equipped to recognize generalized and localized causes of vulvar pain and/or itch.

“The problem is, we don’t talk about [vulvovaginal pain and itch] ... it’s taboo and we’re not taught about it in medical school,” Cigna, assistant professor of obstetrics and gynecology at The George Washington University (GWU), Washington, DC, said in a grand rounds lecture held recently at the GWU School of Medicine and Health Sciences Department of Dermatology.

“There are dermatologists who don’t have much training in vulvar dermatology, and a lot of gyns don’t get as much training” as they should, she said in an interview after the lecture. “So who’s looking at people’s vulvar skin and figuring out what’s going on and giving them effective treatments and evidence-based education?”

Cigna and dermatologist Emily Murphy, MD, will be co-directors of a joint ob.gyn-dermatology Vulvar Dermatology Clinic at GWU that will be launched in 2025, with monthly clinics for particularly challenging cases where the etiology is unclear or treatment is ineffective. “We want to collaborate in a more systematic way and put our heads together and think creatively about what will improve patient care,” Cigna said in the interview.

Dermatologists have valuable expertise in the immunology and genetic factors involved in skin disorders, Cigna said. Moreover, Murphy, assistant professor of dermatology and director of the Vulvar Health Program at GWU, said in an interview, dermatologists “are comfortable in going to off-label systemic medications that ob.gyns may not use that often” and bring to the table expertise in various types of procedures.

Murphy recently trained with Melissa Mauskar, MD, associate of dermatology and obstetrics and gynecology at the University of Texas Southwestern, Dallas, and founder and director of the Gynecologic Dermatology Clinic there. “It’s so important for dermatologists to be involved. It just takes some extra training that residents aren’t getting right now,” said Murphy, a member of the newly formed Vulvar Dermatoses Research Consortium.

In her grand rounds lecture, Cigna offered pearls to dermatologists for approaching a history and exam and covered highlights of the diagnosis and treatment of various problems, from vulvar Candida infections and lichen simplex chronicus to vulvar lichen sclerosus (LS), vulvar lichen planus (LP), vulvar Crohn’s disease, pudendal neuralgia, and pelvic floor muscle spasm, as well as the role of mast cell proliferation in vulvar issues.

 

Approaching the History and Exam

A comprehensive history covers the start, duration, and location of pain and/or itching as well as a detailed timeline (such as timing of potential causes, including injuries or births) and symptoms (such as burning, cutting, aching, and stinging). The question of whether pain “is on the outside, at the entrance, or deeper inside” is “crucial, especially for those in dermatology,” Cigna emphasized.

“And if you’re seeing a patient for a vulvar condition, please ask them about sex. Ask, is this affecting your sexual or intimate life with your partner because this can also give you a clue about what’s going on and how you can help them,” she told the audience of dermatologists.

Queries about trauma history (physical and emotional/verbal), competitive sports (such as daily cycling, equestrian, and heavy weight lifting), endometriosis/gynecologic surgery, connective tissue disorders (such as Ehler-Danlos syndrome), and irritable bowel syndrome are all potentially important to consider. It is important to ask about anxiety, depression, and obsessive-compulsive disorder, which do not cause — but are highly associated with — vulvar dermatoses, she said.

A surprisingly large number of people with vulvovaginal issues are being diagnosed with Ehler-Danlos syndrome, so “I’m always asking, are you hypermobile because this might be affecting the musculoskeletal system, which might be affecting the pelvis,” Cigna said. “Anything that affects the pelvis can affect the vulva as well.”

The pelvic examination should be “offered” rather than assumed to be part of the exam, as part of a trauma-informed approach that is crucial for earning trust, she advised. “Just saying, ‘we’re going to talk, and then I can offer you an exam if you like’…patients like it. It helps them feel safer and more open.”

Many diagnoses are differentiated by eliciting pain on the anterior vs the posterior half of the vulvar vestibule — the part of the vulva that lies between the labia minora and is composed of nonkeratinized tissue with embryonic origins in the endoderm. “If you touch on the keratinized skin (of the vulva) and they don’t have pain, but on the vestibule they do have pain, and there is no pain inside the vagina, this suggests there is a vestibular problem,” said Cigna.

Pain/tenderness isolated to the posterior half of the vestibule suggests a muscular cause, and pain in both the posterior and anterior parts of the vestibule suggests a cause that is more systemic or diffuse, which could be a result of a hormonal issue such as one related to oral contraceptives or decreased testosterone, or a nerve-related process.

Cigna uses gentle swipes of a Q-tip moistened with water or gel to examine the vulva rather than a poke or touch, with the exception being the posterior vestibule, which overlies muscle insertion sites. “Make sure to get a baseline in remote areas such as the inner thigh, and always distinguish between ‘scratchy/sensitive’ sensations and pain,” she said, noting the value of having the patient hold a mirror on her inner thigh.

 

Causes of Vulvar Itch: Infectious and Noninfectious

With vulvar candidiasis, a common infectious cause of vulvar itch, “you have to ask if they’re also itching on the inside because if you treat them with a topical and you don’t treat the vaginal yeast infection that may be co-occurring, they’ll keep reseeding their vulvar skin,” Cigna said, “and it will never be fully treated.”

Candida albicans is the most common cause of vulvar or vulvovaginal candidiasis, and resistance to antifungals has been rising. Non-albicans Candida “tends to have even higher resistance rates,” she said. Ordering a sensitivity panel along with the culture is helpful, but “comprehensive vaginal biome” panels are generally not useful. “It’s hard to correlate the information clinically,” she said, “and there’s not always a lot of information about susceptibilities, which is what I really like to know.”

Cigna’s treatments for vaginal infections include miconazole, terconazole, and fluconazole (and occasionally, itraconazole or voriconazole — a “decision we don’t take lightly”). Vulvar treatments include nystatin ointment, clotrimazole cream, and miconazole cream. Often, optimal treatment involves addressing “both inside and out,” she said, noting the importance of also killing yeast in undergarment fabric.

“In my experience, Diflucan [oral fluconazole] doesn’t treat persistent vulvar cutaneous skin yeast well, so while I might try Diflucan, I typically use something topical as well,” she said. “And with vaginal yeast, we do use boric acid from time to time, especially for non-albicans species because it tends to be a little more effective.”

Noninfectious causes of vulvar itch include allergic, neuropathic, and muscular causes, as well as autoimmune dermatoses and mast cell activation syndrome. Well known in dermatology are acute contact dermatitis and lichen simplex chronicus — both characterized by induration, thickening, and a “puffy” erythematous appearance, and worsening of pruritus at night. What may be less appreciated is the long list of implicated allergens , including Always menstrual pads made of a plastic-containing “dry weave” material, Cigna said. There are at least several cotton-only, low-preservative feminine products available on the market, she noted.

 

Common Autoimmune Vulvar Dermatoses: LS and LP

Vulvar LS has traditionally been thought to affect mainly prepubertal and postmenopausal women, but the autoimmune condition is now known to affect more reproductive-age people with vulvas than previously appreciated, Cigna said.

And notably, in an observational web-based study of premenopausal women (aged 18-50 years) with biopsy-confirmed vulvar LS, the leading symptom was not itch but dyspareunia and tearing with intercourse. This means “we’re missing people,” said Cigna, an author of the study. “We think the reason we’re not seeing itch as commonly in this population is that itch is likely mediated by the low estrogen state of pre- and postmenopausal people.”

Vulvar LS also occurs in pregnancy, with symptoms that are either stable or decrease during pregnancy and increase in the postpartum period, as demonstrated in a recently published online survey.

Patients with vulvar LS can present with hypopigmentation, lichenification, and scarring and architectural changes, the latter of which can involve clitoral phimosis, labial resorption, and narrowing of the introitus. (The vaginal mucosa is unaffected.) The presentation can be subtle, especially in premenopausal women, and differentiation between LS, vitiligo, and yeast is sometimes necessary.

A timely biopsy-driven definitive diagnosis is important because vulvar LS increases the risk for cancer if it’s not adequately treated and because long-term steroid use can affect the accuracy of pathology reports. “We really care about keeping this disease in remission as much as possible,” Cigna said. Experts in the field recommend long-term maintenance therapy with a mid-ultra-potent steroid one to three times/week or an alternative. “I’ve just started using ruxolitinib cream, a Janus kinase (JAK) inhibitor, and tacrolimus, a calcineurin inhibitor,” she said.

Neuropathic Itch, Pelvic Floor Muscle Spasm

Patients with pudendal neuralgia — caused by an injured, entrapped, or irritated pudendal nerve (originating from S2-S4) — typically present with chronic vulvar and pelvic pain that is often unprovoked and worsens with sitting. Itching upon touch is often another symptom, and some patients describe a foreign body sensation.

Diagnosis and treatment usually start with a pudendal nerve block with a combination of steroid and anesthetic. If this does not relieve arousal/itching, the next step may be an MRI to look higher in the spine.

 

Pelvic Floor Muscle Spasm

Vulvar pain, skin itching, and irritation can be symptoms of pelvic floor muscle spasm. “Oftentimes people come to me and say, ‘I have a dermatologic problem,’” Cigna said. “The skin may look red and erythematous, but it’s probably more likely a muscle problem when you’re not finding anything, and no amount of steroid will help the itch go away when the problem lies underneath.”

Co-occurring symptoms can include vaginal dryness, clitoral pain, urethral discomfort, bladder pain/irritation, increased urgency, constipation, and anal fissures. The first-line treatment approach is pelvic floor therapy.

“Pelvic floor therapy is not just for incontinence. It’s also for pain and discomfort from muscles,” she said, noting that most patients with vulvar disorders are referred for pelvic floor therapy. “Almost all of them end up having pelvic floor dysfunction because the pelvic floor muscles spasm whenever there’s pain or inflammation.”

 

A Cautionary Word on Vulvodynia, and a Mast Cell Paradigm to Explore

Vulvodynia is defined as persistent pain of at least 3 months’ duration with no clear cause. “These are the patients with no skin findings,” Cigna said. But in most cases, she said, careful investigation identifies causes that are musculoskeletal, hormonal, or nerve-related.

“It’s a term that’s thrown around a lot — it’s kind of a catchall. Yet it should be a small minority of patients who truly have a diagnosis of vulvodynia,” she said.

In the early stages of investigation is the idea that mast cell proliferation and mast cell activation may play a role in some cases of vulvar and vestibular pain and itching. “We see that some patients with vulvodynia and vestibulodynia have mast cells that are increased in number in the epithelium and beneath the epithelium, and nerve staining shows an increased number of nerve endings traveling into the epithelium,” Cigna said.

“We do diagnose some people clinically” based on urticaria and other symptoms suggestive of mast cell proliferation/activation (such as flushing, abdominal cramping, diarrhea, hypotensive syncope or near syncope, and tachycardia), and “then we send them to the allergist for testing,” Cigna said.

Cigna and Murphy have no relevant financial disclosures.

New recommendations from the WikiGuidelines Group offer strategies for the prevention, diagnosis, and management of urinary tract infections (UTIs) in children and adults.

While the guideline covers a range of clinical topics, including prophylaxis and antimicrobial stewardship, many key clinical questions remain unanswered because of a lack of high-quality evidence, according to lead author Zachary Nelson, PharmD, MPH, of HealthPartners and Park Nicollet Health Services, St. Louis Park, Minnesota, and colleagues.

“This guideline fills a critical gap by providing pragmatic, broadly applicable recommendations tailored for generalist care and systems-based practice,” Nelson and colleagues wrote in JAMA Network Open. “Our guidance is rooted in the best available evidence and is designed for clinicians from various backgrounds and healthcare environments. It emphasizes a patient-centered approach to the diagnosis, prevention, and treatment of UTIs and related genitourinary infections.”

The guideline panelists, including 54 experts from 12 countries, developed the document in accordance with Standards for Quality Improvement Reporting Excellence and the WikiGuidelines charter. The latter requires that “clear recommendations” are based on data from at least two concordant randomized clinical trials (RCTs), or one RCT plus one concordant prospective observational study.

This approach allowed the panel to provide clear recommendations for 6 out of 37 unique questions, while 3 other questions were partially answered. In other words, 75% of the questions lacked sufficient evidence for answers.

“These guidelines are important because they illuminate the clinical data and lack of data we have for approaching diagnosis and treatment of this common infection that leads to a wide array of morbidity and sometimes mortality, as well as significant cost burden to the healthcare system,” said coauthor Sarah Kurz, MD, clinical assistant professor of internal medicine at Michigan Medicine, Ann Arbor, in a written comment.

Jessica Hammett, MD, a urologist at Emory Healthcare, Atlanta, Georgia, who was not an author of the study, suggested that the guideline is additionally impactful because of the panel’s geographic diversity.

“It is an international collaboration that takes into account regional and international practice patterns and differences,” Hammett said in a written comment.

The key guideline recommendations are briefly summarized below.

Preventive Strategies for UTI

The guideline endorses cranberry products as preventive for UTI-prone women, children, and post-intervention patients, though data are insufficient to recommend them for older adults, those with bladder issues, or pregnant women.

Topical estrogen is recommended for postmenopausal women with recurrent UTIs, as it helps restore the vaginal microbiome with minimal systemic absorption. It may also benefit patients with breast cancer when nonhormonal alternatives fail.

For those with intact bladder anatomy, methenamine hippurate is suggested as a noninferior alternative to low-dose antibiotics for preventing recurrent UTIs.

“These findings confirm the best practice of starting postmenopausal women on vaginal estrogen to prevent UTIs, which is a treatment option that should be implemented more commonly,” Hammett said. “Interestingly as compared to the AUA guidelines, this paper recommends the use of cranberry supplementation and methenamine as antibiotic alternatives for preventing UTIs.”

 

Empirical Treatment Recommendations

According to the guideline, empirical treatment for UTIs should focus on antimicrobials with high urinary tract concentration and local pathogen efficacy.

Nitrofurantoin is recommended for uncomplicated cystitis, while trimethoprim/sulfamethoxazole (TMP/SMX) and first-generation cephalosporins are advised for pyelonephritis.

For intravenous therapy, ceftriaxone is preferred unless there are risk factors for multidrug resistance.

Recommended treatment durations include 5 days for nitrofurantoin, 3 days for TMP/SMX and fluoroquinolones, and a single dose for fosfomycin in acute cystitis cases. For acute pyelonephritis, fluoroquinolones are advised for 5-7 days, with dose-optimized beta-lactams for 7 days. Gram-negative bacteremia from urinary sources warrants a 7-day course.

 

Stewardship and Clinical Management

The guideline emphasizes antimicrobial stewardship, with support for antibiotic de-escalation and oral regimens where feasible, to reduce adverse effects and hospital stays. Although evidence is limited, the authors suggest thorough allergy assessment and selective reporting of susceptibility results to enhance antibiotic selection.

While data were insufficient to make clear recommendations about the treatment of asymptomatic bacteriuria, Nelson and colleagues suggested that this practice “risks side effects without benefit” while threatening antimicrobial sustainability.

Hammett agreed, noting that “[this] serves as an important reminder not to treat asymptomatic bacteriuria, as it increases side effects and bacterial resistance without any improvement as compared to placebo.”

 

Special Considerations for Urologic Procedures

Finally, patients undergoing urologic procedures, routine cystoscopy, and urodynamic studies generally do not require prophylactic antibiotics, according to the guideline. Single-dose antibiotic prophylaxis is recommended for low-risk nephrolithotomy patients, though high-risk individuals, such as those who are pregnant or post kidney transplant, may require extended prophylaxis.

Kurz suggested that the guideline consolidates and supports the foundation of evidence driving common practices.

“I don’t think these guidelines offer any strikingly new strategies, which is unsurprising, as they were created after a deep dive into existing literature,” Kurz said. “But more importantly, what I think they do is to highlight where and what the evidence is for many of the clinical strategies that are commonly employed. For example, in terms of prevention, it is common for primary care physicians, urologists, and infectious diseases doctors to recommend cranberry and hydration and to use methenamine. These guidelines highlight that there is sufficient quality and quantity of evidence to support these interventions.”

She also noted how the guidelines emphasize the need for symptoms to make a UTI diagnosis and advise against routine testing of asymptomatic individuals.

“Despite this not being new information, typical clinical practice is often out of step here, and this [guideline] reemphasizes the important factors when considering UTI diagnosis,” Kurz said.

Finally, she expressed frustration for the numerous knowledge gaps remaining in this area, which may be traced back to barriers ranging from the semantic to the more systemic.

“Some of the difficulty is lack of clear definitions and precise terminology regarding UTIs,” Kurz said, noting the unclear distinction between complicated and uncomplicated UTIs. “I would also argue that UTIs are a disease that predominantly affects women, and like many other diseases where this is the case, [they] tend to be less studied. Hopefully, this guideline’s spotlight on all that we do not know can inspire high-quality research to address these gaps, leading to optimal patient care along with decreased burden on the system as a whole in terms of cost and antimicrobial resistance.”

The study was funded by Merck. The WikiGuidelines Group that established this guideline is entirely voluntary and unpaid; the group intends to establish a nonprofit organization to support the development of other guidelines using this novel methodology and eventually intends to trademark the name WikiGuidelines. The authors disclosed relationships with Pfizer, Eumedica, GSK, and others.
