Cultural competency is one of the most important values in the practice of medicine. Defined as the “ability to collaborate effectively with individuals from different cultures,” this type of competence “improves healthcare experiences and outcomes.” But within the context of cultural familiarity, it’s equally important to “understand that each person is an individual and may or may not adhere to certain cultural beliefs or practices common in his or her culture,” according to the Agency for Healthcare Research and Quality’s (AHRQ’s) Health Literacy Universal Precautions Toolkit.

Sarah Candler, MD, MPH, an internal medicine physician specializing in primary care for older adults in Washington, DC, said that the medical code of ethics consists of several pillars, with patient autonomy as the “first and most primary of those pillars.” She calls the balance of patient autonomy and cultural respect a “complicated tightrope to walk,” but says that these ethical principles can inform medical decisions and the patient-physician relationship.

 

Cultural Familiarity

It’s important to be as familiar as possible with the patient’s culture, Santina Wheat, MD, program director, Northwestern McGaw Family Medicine Residency at Delnor Hospital, Geneva, told this news organization. “For example, we serve many Orthodox Jewish patients. We had a meeting with rabbis from the community to present to us what religious laws might affect our patients. Until recently, I was delivering babies, and there was always a 24-hour emergency rabbi on call if an Orthodox patient wanted the input of a rabbi into her decisions.”

Jay W. Lee, MD, MPH, a member of the board of directors of the American Academy of Family Physicians, also sets out to educate himself about the cultural norms of his patients if they come from populations he’s not familiar with. “For example, this comes up when a new refugee population comes to the United States — most recently, there was a population of Afghan refugees,” Lee told this news organization.

Lee spent “a lot of time trying to learn about their cultural norms,” which prepared him to “ask more targeted questions about the patient’s understanding of the tests we were ordering or treatment options we were bringing forward.”

Lee, also the medical director at Integrated Health Partners of Southern California and associate clinical professor of family medicine at the University of California, Irvine, said it might be best if the physician is “language congruent or culturally similar.” Lee is of Asian descent and also speaks Spanish fluently. “I enjoy cultural exchanges with my patients, and I encourage patients to find a physician who’s the best fit.” But being from the same culture isn’t absolutely necessary for building relationships with the patient. “The key is offering the patient autonomy” while understanding the cultural context.

 

Don’t Assume ... Always Ask

Cultural familiarity doesn’t equate with stereotyping, Wheat emphasized. “Proceeding without assumptions opens the opportunity to ask questions for clarification and understanding and to improve patient care,” said Lee.

Sara Glass, PhD, LCSW, agrees. She’s the clinical director of Soul Wellness NYC, New York City, a psychotherapy practice that specializes in treating trauma. Based on her own experiences, she knows that some physicians and other healthcare professionals confuse cultural sensitivity with cultural stereotyping.

Glass, formerly Hasidic and ultra-Orthodox, shared an example from her own life. During the delivery of her second child, she sustained a vaginal tear. At her 6-week postpartum visit, her ob/gyn said, “Just remind me when you’re in your ninth month next time, and I can sew it up right after you deliver.”

Much of this physician’s practice “consisted of Hasidic women who looked just like me, wearing the same garb — head coverings such as wigs and scarves and long skirts. Most women in that community have multiple pregnancies,” Glass told this news organization. “My sister has 10 children, and that’s not unusual. The doctor simply assumed I’d be going on to have more babies without asking if that’s what I wanted.”

Glass says she was also never given information by her physician about the range of available contraceptive options. The rabbis of the Hasidic sect to which Glass belonged allowed women to practice contraception for 6 months following childbirth, or for longer, in the setting of certain medical conditions, but only certain types of birth control were religiously permissible. Other options were not mentioned to her by her physician, and she didn’t know that they existed.

Making no assumptions applies not only to patients from other cultures but also to all patients — including members of “mainstream American culture.”

Candler recalls a young patient with a new baby, who shared “how exhausted she was and how much time, energy, and work it took to care for children,” Candler recounted. “To me, it sounded as though she didn’t want another child, and I was about to offer contraception when it occurred to me to first ask if she wanted to have more children.” Candler was surprised when the patient said that, although she wasn’t actively looking to become pregnant again, she didn’t want to take preventive measures. “I’m so glad I asked, rather than simply assuming.”

 

Culture Is Mutable

Important questions to ask patients include whether there are aspects of their culture or religion that might affect their care — which can include medications they may feel uncomfortable using — and what family members they want to have involved in clinical discussions and decisions, said Wheat.

Lee described treating a refugee from Afghanistan who was in her sixth month of pregnancy. “I quickly needed to learn about what her expectations were for her care and my presence as a male on her care team,” he recounted. Lee arranged for the patient to receive prenatal care from a different clinician and arranged for follow-up for her husband and children. “Everyone had good results.”

Candler noted that some patients choose their physician specifically because that practitioner is conversant with their culture and respectful of its mores — especially when physicians share the same culture as the patient. But that level of familiarity can make it easy to forget to ask questions about the experience of the individual patient within that culture.

Moreover, Glass suggested, some physicians who treat patients from a particular culture or religious group may be concerned about offending them or antagonizing religious leaders if they discuss medical options that aren’t accepted or practiced in that community or culture, such as vasectomy for male contraception. “But that deprives patients of knowing what choices are available and making truly informed decisions.”

This is especially important because “culture is mutable,” said Candler, and religious or cultural practices can “look one way on paper but be implemented, adopted, or executed in a completely different way by every human being who lives in that culture.” The best cultural competency “comes from continuing to build relationships with our patients. But even in a single visit, a single hospitalization, we should get to know patients as human beings, not just members of a given culture.”

There are cultures in which families want to be the liaison between the patient and the physician and to make decisions on the patient’s behalf. “I always ask patients what role they want their family members to play even if the cultural expectation is that the family will be heavily involved,” Candler said.

Sometimes, this can be awkward, and families might become upset. Candler described an elderly, frail patient who was diagnosed with end-stage cancer. She had always relied heavily on family to care for her. Concerned about overburdening them, she didn’t want them to know her diagnosis. The patient was mentally competent to make that decision.

“Usually, I would have had the family at the bedside so I could be sure everyone was appropriately informed and prepared for what lay ahead, but in this case, I couldn’t do so,” Candler said. “I had to inform her entire care team not to discuss the cancer diagnosis with any family members because this was the patient’s express wish. And when the family asked me if the diagnosis was cancer, I had to respond, ‘I’m so sorry, but your loved one doesn’t want us to discuss details of her diagnosis.’”

Other patients don’t want to know their own diagnosis and specifically ask Candler to inform a family member. “I’ve had patients request that I tell their children. They want their children to make decisions on their behalf.”

The main thing, Candler emphasized, is to “ask the patient, make sure the patient is competent to make that decision, thoroughly document the patient’s decision in the chart, and respect whatever that decision is.”

 

You Can Revisit the Questions

Having a longitudinal relationship means that the physician can revisit the same questions at different junctures because people’s perspectives sometimes change over time. “Discussing what a patient wants isn’t necessarily a one-time occurrence,” Wheat said. For example, “I’ve had situations where a patient has been a member of Jehovah’s Witnesses and won’t accept blood products — like transfusions — in treatment. I tell these patients that if an emergent situation arises, I would like to have the conversation again.”

Of course, sometimes patients are seen in the emergency department or in other situations where the physician has no prior relationship with them. “I always go into a room, especially with new patients, aiming to build rapport, communicate with a high level of respect, introduce myself, explain my approach, and understand the patient’s wishes,” Lee said. “As scenarios play out, I ask in multiple ways for the patient to confirm those wishes.”

He acknowledges that this can be time-consuming, “but it helps ensure the care that patient receives is complete, thorough, comprehensive, and respectful of the patient’s values and wishes.”

Candler disclosed paid part-time clinical work at CuraCapitol Primary Care Services, volunteer advocacy (reimbursed for travel) for the American College of Physicians, volunteer advocacy (reimbursed for travel) for the American Medical Association while serving on their Task Force to Preserve the Patient-Physician Relationship, and serving as a partner representative (reimbursed for time) for the AHRQ’s Person-Centered Care Planning Partnership, representing the American College of Physicians. Lee, Wheat, and Glass disclosed no relevant financial relationships.

New allergens responsible for contact dermatitis emerge regularly. During the Dermatology Days of Paris 2024 conference, Angèle Soria, MD, PhD, a dermatologist at Tenon Hospital in Paris, France, outlined four major categories driving this trend. Among them are (meth)acrylates found in nail cosmetics used in salons or do-it-yourself false nail kits that can be bought online.

Isothiazolinones

While the prevalence of allergic contact dermatitis remains stable at around 20% of the population, new allergens are introduced due to changes in cosmetic formulations and evolving consumer habits. Recent culprits include methylisothiazolinone (MI), a preservative used in many cosmetics; (meth)acrylates; essential oils; and epoxy resins used in industry and leisure activities.

Around 15 years ago, parabens, commonly used as preservatives in cosmetics, were identified as endocrine disruptors. In response, they were largely replaced by newer preservatives, notably MI. However, this led to a proliferation of allergic contact dermatitis in Europe between 2010 and 2013.

“About 10% of the population that we tested showed allergies to these preservatives, primarily found in cosmetics,” explained Soria. Since 2015, the use of MI in leave-on cosmetics has been prohibited in Europe and its concentration restricted in rinse-off products. However, cosmetics sold online from outside Europe may not comply with these regulations.

MI is also present in water-based paints to prevent mold. “A few years ago, we started seeing patients with facial angioedema, sometimes combined with asthma, caused by these isothiazolinone preservatives, including in patients who are not professional painters,” said Soria. More recently, attention has shifted to MI’s presence in household cleaning products. A 2020 Spanish study found MI in 76% of 34 analyzed cleaning products.

MI-based fungicides are also used to treat leather during transport, which can lead to contact allergies among professionals and consumers alike. Additionally, MI has been identified in children’s toys, including slime gels, and in florists’ gel cubes used to preserve flowers.

“We are therefore surrounded by these preservatives, which are no longer only in cosmetics,” warned the dermatologist.

 

(Meth)acrylates

Another major allergen category is (meth)acrylates, responsible for many cases of allergic contact dermatitis. Acrylates and their derivatives are widely used in everyday items. They are low–molecular weight monomers, sensitizing on contact with the skin. Their polymerized forms include materials like Plexiglas.

“We are currently witnessing an epidemic of contact dermatitis in the general population, mainly due to nail cosmetics, such as semipermanent nail polishes and at-home false nail kits,” reported Soria. Nail cosmetics account for 97% of new sensitization cases involving (meth)acrylates. These allergens often cause severe dermatitis, prompting the European Union to mandate labeling in 2020, warning that these products are “for professional use only” and can “cause allergic reactions.”

Beyond nail cosmetics, these allergens are also found in dental products (such as trays), ECG electrodes, prosthetics, glucose sensors, surgical adhesives, and some electronic devices like earbuds and phone screens. Notably, patients sensitized to acrylates via nail kits may experience reactions during dental treatments involving acrylates.

 

Investigating Essential Oil Use

Essential oils, distinct from vegetable oils like almond or argan, are another known allergen. Often considered risk-free due to their “natural” label, these products are widely used topically, orally, or via inhalation for various purposes, such as treating respiratory infections or creating relaxing atmospheres. However, essential oils contain fragrant molecules like terpenes, which can become highly allergenic over time, especially after repeated exposure.

Soria emphasized the importance of asking patients about their use of essential oils, especially tea tree and lavender oils, which are commonly used but rarely mentioned by patients unless prompted.

 

Epoxy Resins in Recreational Use

Epoxy resins are a growing cause of contact allergies, not just in professional settings such as aeronautics and construction work but also increasingly in recreational activities. Soria highlighted the case of a 12-year-old girl hospitalized for severe facial edema after engaging in resin crafts inspired by TikTok. For 6 months, she had been creating resin objects, such as bowls and cutting boards, using vinyl gloves and a Filtering FacePiece 2 mask under adult supervision.

“The growing popularity and online availability of epoxy resins mean that allergic reactions should now be considered even in nonprofessional contexts,” warned Soria.

 

Clinical Approach

When dermatologists suspect allergic contact dermatitis, the first step is to treat the condition with corticosteroid creams. This is followed by a detailed patient interview to identify suspected allergens in products they’ve used.

Patch testing is then conducted to confirm the allergen. Small chambers containing potential allergens are applied to the upper back for 48 hours without removal. Results are read 2-5 days later, with some cases requiring a 7-day follow-up.

The patient’s occupation is an important factor, as certain professions, such as hairdressing, healthcare, or beauty therapy, are known to trigger allergic contact dermatitis. Similarly, certain hobbies may also play a role. 

A thorough approach ensures accurate diagnosis and targeted prevention strategies.

More recently, attention has shifted to MI’s presence in household cleaning products. A 2020 Spanish study found MI in 76% of 34 analyzed cleaning products.

MI-based fungicides are also used to treat leather during transport, which can lead to contact allergies among professionals and consumers alike. Additionally, MI has been identified in children’s toys, including slime gels, and in florists’ gel cubes used to preserve flowers.

“We are therefore surrounded by these preservatives, which are no longer only in cosmetics,” warned the dermatologist.

 

(Meth)acrylates

Another major allergen category is (meth)acrylates, responsible for many cases of allergic contact dermatitis. Acrylates and their derivatives are widely used in everyday items. They are low–molecular weight monomers, sensitizing on contact with the skin. Their polymerized forms include materials like Plexiglas.

“We are currently witnessing an epidemic of contact dermatitis in the general population, mainly due to nail cosmetics, such as semipermanent nail polishes and at-home false nail kits,” reported Soria. Nail cosmetics account for 97% of new sensitization cases involving (meth)acrylates. These allergens often cause severe dermatitis, prompting the European Union to mandate labeling in 2020, warning that these products are “for professional use only” and can “cause allergic reactions.”

Beyond nail cosmetics, these allergens are also found in dental products (such as trays), ECG electrodes, prosthetics, glucose sensors, surgical adhesives, and some electronic devices like earbuds and phone screens. Notably, patients sensitized to acrylates via nail kits may experience reactions during dental treatments involving acrylates.

 

Investigating Essential Oil Use

Essential oils, distinct from vegetable oils like almond or argan, are another known allergen. Often considered risk-free due to their “natural” label, these products are widely used topically, orally, or via inhalation for various purposes, such as treating respiratory infections or creating relaxing atmospheres. However, essential oils contain fragrant molecules like terpenes, which can become highly allergenic over time, especially after repeated exposure.

Soria emphasized the importance of asking patients about their use of essential oils, especially tea tree and lavender oils, which are commonly used but rarely mentioned by patients unless prompted.

 

Epoxy Resins in Recreational Use

Epoxy resins are a growing cause of contact allergies, not just in professional settings such as aeronautics and construction work but also increasingly in recreational activities. Soria highlighted the case of a 12-year-old girl hospitalized for severe facial edema after engaging in resin crafts inspired by TikTok. For 6 months, she had been creating resin objects, such as bowls and cutting boards, using vinyl gloves and a Filtering FacePiece 2 mask under adult supervision.

“The growing popularity and online availability of epoxy resins mean that allergic reactions should now be considered even in nonprofessional contexts,” warned Soria.

 

Clinical Approach

When dermatologists suspect allergic contact dermatitis, the first step is to treat the condition with corticosteroid creams. This is followed by a detailed patient interview to identify suspected allergens in products they’ve used.

Patch testing is then conducted to confirm the allergen. Small chambers containing potential allergens are applied to the upper back for 48 hours without removal. Results are read 2-5 days later, with some cases requiring a 7-day follow-up.

The patient’s occupation is an important factor, as certain professions, such as hairdressing, healthcare, or beauty therapy, are known to trigger allergic contact dermatitis. Similarly, certain hobbies may also play a role. 

A thorough approach ensures accurate diagnosis and targeted prevention strategies.

New allergens responsible for contact dermatitis emerge regularly. During the Dermatology Days of Paris 2024 conference, Angèle Soria, MD, PhD, a dermatologist at Tenon Hospital in Paris, France, outlined four major categories driving this trend. Among them are (meth)acrylates found in nail cosmetics used in salons or do-it-yourself false nail kits that can be bought online.

Isothiazolinones

While the prevalence of allergic contact dermatitis remains stable at around 20% of the population, new allergens are introduced due to changes in cosmetic formulations and evolving consumer habits. Recent culprits include methylisothiazolinone (MI), a preservative used in many cosmetics; (meth)acrylates; essential oils; and epoxy resins used in industry and leisure activities.

Around 15 years ago, parabens, commonly used as preservatives in cosmetics, were identified as endocrine disruptors. In response, they were largely replaced by newer preservatives, notably MI. However, this led to a proliferation of allergic contact dermatitis in Europe between 2010 and 2013.

“About 10% of the population that we tested showed allergies to these preservatives, primarily found in cosmetics,” explained Soria. Since 2015, the use of MI in leave-on cosmetics has been prohibited in Europe and its concentration restricted in rinse-off products. However, cosmetics sold online from outside Europe may not comply with these regulations.

MI is also present in water-based paints to prevent mold. “A few years ago, we started seeing patients with facial angioedema, sometimes combined with asthma, caused by these isothiazolinone preservatives, including in patients who are not professional painters,” said Soria.

Oh, insurance claim denials. When patient care or treatment is warranted by a specific diagnosis, I wish insurers would just reimburse it without any hassle. That’s not reality. Let’s talk about insurance claim denials, how they’re rising and harming patient care, and what we can do about it. That’s kind of complicated.

Rising Trend in Claim Denials and Financial Impact

First, denials are increasing. Experian Health surveyed provider revenue cycle leaders— that’s a fancy term for people who manage billing and insurance claims — and 75% said that denials are increasing. This is up from 42% a few years ago. Those surveyed also said that reimbursement times and errors in claims are also increasing, and changes in policy are happening more frequently. This all adds to the problem. 

Aside from being time-consuming and annoying, claim denials take a toll on hospitals and patients. One analysis, which made headlines everywhere, showed that hospitals and health systems spent nearly $20 billion in 2022 trying to repeal overturned claims. This analysis was done by Premier, a health insurance performance company.

 

Breakdown of Denial Rates and Costs

Let’s do some quick whiteboard math. Health insurance companies get about 3 billion claims per year. According to surveys, about 15% of those claims are denied, so that leaves us with 450 million denied claims. Hospitals spend, on average, $43.84 per denied claim in administrative fees trying to get them overturned.

That’s about $19.7 billion spent on claim denials. Here’s the gut punch: Around 54% of those claims are ultimately paid, so that leaves us with $10.7 billion that we definitely should have saved. 

 

Common Reasons for Denials

Let’s take a look at major causes and what’s going on. 

Insurance denial rates are all over the place. It depends on state and plan. According to one analysis, the average for in-network claim denials across some states was 4% to 5%. It was 40% in Mississippi. According to HealthCare.gov, in 2021, around 17% of in-network claims were denied. 

The most common reasons were excluded services, a lack of referral or preauthorization, or a medical treatment not being deemed necessary. Then there’s the black box of “other,” just some arbitrary reason to make a claim denial. 

Many times, these denials are done by an algorithm, not by individual people. 

What’s more, a Kaiser Family Foundation analysis found that private insurers, including Medicare Advantage plans, were more likely to deny claims than public options. 

When broken down, the problem was higher among employer-sponsored and marketplace insurance, and less so with Medicare and Medicaid. 

 

Impact on Patient Care

Many consumers don’t truly understand what their health insurance covers and what’s going to be out of pocket, and many people don’t know that they have appeal rights. They don’t know who to call for help either. 

The ACA set up Consumer Assistance Programs (CAPs), which are designed to help people navigate health insurance problems. By law, private insurers have to share data with CAPs. Yet, only 3% of people who had trouble with health insurance claims called a CAP for help.

We all know some of the downstream effects of this problem. Patients may skip or delay treatments if they can’t get insurance to cover it or it’s too expensive. When post-acute care, such as transfer to a skilled nursing facility or rehab center, isn’t covered and we’re trying to discharge patients from the hospital, hospital stays become lengthened, which means they’re more expensive, and this comes with its own set of complications.

 

How Can We Address This?

I’m genuinely curious about what you all have done to efficiently address this problem. I’m looking at this publication from the American Health Information Management Association about major reasons for denial. We’ve already talked about a lack of preauthorization or procedures not being covered, but there are also reasons such as missing or incorrect information, duplicate claims, and not filing within the appropriate time.

Also, if treatments or procedures are bundled, they can’t be filed separately. 

Preventing all of this would take a large effort. Healthcare systems would have to have a dedicated team, who would understand all the major reasons for denials, identify common patterns, and then fill everything out with accurate information, with referrals, with preauthorizations, high-specificity codes, and the correct modifiers — and do all of this within the filing deadline every time. 

You would need physicians on board, but also people from IT, finance, compliance, case management, registration, and probably a bunch of other people who are already stretched too thin. 

Perhaps our government can do more to hold insurers accountable and make sure plans, such as Medicare Advantage, are holding up their end of the public health bargain.

It’s an uphill $20 billion battle, but I’m optimistic. What about you? What’s your unfiltered take on claim denials? What more can we be doing?

Dr. Patel is a clinical instructor, Department of Pediatrics, Columbia University College of Physicians and Surgeons; pediatric hospitalist, Morgan Stanley Children’s Hospital of NewYork-Presbyterian, New York City, and Benioff Children’s Hospital, University of California, San Francisco. He reported a conflict of interest with Medumo.

Despite being a targeted therapy, antibody-drug conjugates (ADCs) can cause significant off-target toxicity to the eyes of patients being treated for advanced multiple myeloma or cervical cancer, yet the risks remain relatively unknown, according to oncologists and ophthalmologists.

Such experts called for greater collaboration between oncologists and ophthalmologists, in interviews with Medscape Medical News.

ADCs combine a monoclonal antibody targeted at an antigen overexpressed on cancer cells with a toxic chemotherapy payload — the aim being to maximize the effectiveness of the drug against the tumor while minimizing the damage to healthy tissues and reducing systemic toxicity.

Yet trastuzumab duocarmazine (T-Duo), a third-generation human epidermal growth factor receptor 2 (HER2)–targeted ADC designed to treat HER2-positive breast cancer, was recently found to have a notable adverse effect in the TULIP trial of 437 patients.

As reported by Medscape Medical News, the drug was associated with a significant increase in progression-free survival over physician’s choice of therapy. However, 78% of patients in the ADC group experienced at least one treatment-emergent ocular toxicity adverse event vs 29.2% of those in the control group.

Moreover, grade 3 or high ocular toxicity events were reported by 21% of patients in the experimental group compared with none of those who received physician’s choice.

 

Ocular Toxicities Seen on Ocular Surface

Ocular toxicities with these drugs are “not necessarily a new thing,” said Joann J. Kang, MD, director, Cornea and Refractive Surgery, and associate professor of ophthalmology at Albert Einstein College of Medicine, Montefiore Medical Center, Bronx, New York.

“But what we’re seeing with certain ADCs is a lot of ocular toxicity, especially on the ocular surface,” with the degree toxicity varying depending on the ADC in question. “It’s definitely a real concern.”

Kang noted that separate from T-Duo, certain ADCs already come with black box warnings for ocular toxicity, including:

• Belantamab mafodotin (Blenrep) — approved for relapsed or refractory multiple myeloma and carries a warning specifically for keratopathy.
• Tisotumab vedotin (Tivdak) — indicated for recurrent or metastatic cervical cancer and can cause changes in the corneal epithelium and conjunctiva.
• Mirvetuximab soravtansine (Elahere) — used to treat folate receptor (FR) alpha–positive ovarian, fallopian tube, and peritoneal cancers and can lead to keratopathy, blurred vision, and dry eyes.

Indeed, the American Academy of Ophthalmology 2024 annual meeting saw research presented indicating that mirvetuximab was associated with moderate or severe corneal toxicity in 47% of patients treated for primary gynecologic malignancies.

As reported by Medscape Medical News, the study, by researchers at Byers Eye Institute of Stanford University in Stanford, California, was a retrospective analysis of 36 eyes of 18 women who received mirvetuximab for FR alpha–positive, platinum-resistant primary ovarian cancer.

 

What Are the Causes?

But why would a drug that is targeted specifically to a cancer tumor, thanks to the presence of a monoclonal antibody, cause off-target effects such as ocular toxicity?

Kathy D. Miller, MD, professor of oncology and medicine at Indiana University School of Medicine in Indianapolis, pointed out that they are targeted in a relative and not absolute sense, meaning that the antigen target may not be truly limited to the tumor cells.

There can also be “a lot of ways that you could get systemic toxicities,” she said.

For example, if the linker connecting the antibody and the chemotherapy payload breaks prematurely or is not stable, or if the drug leaches out into the tumor microenvironment and then is “picked up into the circulation, that can give you systemic toxicity,” she said.

In addition, the drug may, once it is in the tumor cells, be metabolized to an active metabolite that could, again, result in systemic exposure.

 

Side Effects Are Underappreciated and Distressing

Ocular toxicity remains underappreciated among oncologists prescribing these drugs. One reason is that it “did not get enough attention” in the initial clinical trial reports, Miller said she suspects.

Another potential reason for this is that “we’re not used to thinking about it because it’s not particularly common among the drugs that oncologists use frequently,” she added. Additionally, it tends to come up later during treatment, “so people have to be on therapy for some time before you start to see it.”

Nevertheless, Miller underlined that ocular toxicity “can be particularly distressing for patients, as it’s uncomfortable [and] can lead to scarring, so some of the vision issues can be permanent.”

“We often see in these situations that there are different types of ocular toxicities that present in different patients,” said Jane L. Meisel, MD, co-director, Breast Medical Oncology, Department of Hematology and Medical Oncology at Emory University School of Medicine in Atlanta.

“Corneal damage is pretty common, and patients can present with blurry vision, or dry eyes, or light sensitivity. And unlike some side effects, these are things that really impact people at every waking moment of their day.”

“So they’re pretty clinically significant side effects, even if they’re not life-threatening,” Meisel emphasized.

Miller suspects that more heavily pretreated patients may be more likely to experience ocular toxicity, as “there’s a much higher incidence of dry eyes in our patients than we recognize.”

She added: “We don’t usually ask about it, and we certainly don’t routinely do Schirmer’s tests,” which determine whether the eye produces enough tears to keep it moist.

 

Preventive Measures

For patients receiving tisotumab or mirvetuximab who experience ocular toxicity, Kang said the recommendation is to use steroid eye drops before, during, and after treatment with the ADC.

However, she noted that steroids have not been found to be useful in patients given belantamab, so clinicians have tried vasoconstrictor eye drops immediately prior to the infusion, as well as ocular cooling masks, which “are thought to help by reducing blood supply to the ocular areas.”

Other approaches to minimize ocular toxicity have included longer infusion times, so it’s “not so much of a hefty dose at one time,” Kang added.

She underlined that grade 2 and 3 ocular toxicities can lead to dose delays or dose modifications, and “usually by the time you get a grade 4 event, then you may need to discontinue the medication.”

This can have consequences for the patients because they are often “very sick, and this may be their third agent that they’re trying,” or it may be that their tumor is responding to a new treatment, but it has to be withheld because of an ocular toxicity.

“It can be incredibly frustrating for patients, and also for oncologists, and then for ophthalmologists,” Kang said.

 

Closer Collaboration Between Specialists Needed

What’s known about ocular side effects in patients taking ADCs underlines that there is a need for closer collaboration between oncologists and ophthalmologists.

“In oncology, especially as immunotherapies came to the forefront, our relationships with our endocrinology colleagues have become stronger because we’ve needed them to help us manage things like thyroid toxicity and pituitary issues related to immunotherapy,” Meisel said.

With toxicities that may be “very impactful for patient quality of life, like ocular toxicity, we will need to learn more about them and develop protocols for management, along with our ophthalmology colleagues, so that we can keep patients as comfortable as possible, while maximizing the efficacy of these drugs.”

Miller agreed, saying oncologists need to have “a conversation with a local ophthalmologist,” although she conceded that, in many areas, such specialists “are in short supply.”

The oncologist “not only needs to be aware” of and looking for ocular toxicity when using these ADCs but also needs to be thinking: “If I run into trouble here, who’s my ophthalmology backup? Are they familiar with this drug? And do we have a plan for the multispecialty management of patients who run into this toxicity?”

 

Setting Counts When Assessing Toxicities

But do all these considerations mean that ADCs’ potential ocular toxicity should give clinicians pause when considering whether to use these drugs?

“What my patients most want are drugs that work; that are effective in controlling their tumors,” Miller said.

“Every drug we use has potential toxicities, and which toxicities are most physically troublesome [or] are the greatest concern may vary from patient to patient, and it may vary a lot from patients with metastatic disease to those in the curative setting.”

She explained that “toxicities that might not be prohibitive at all in the metastatic setting [may] have to be a much bigger part of our considerations” when moving drugs into the adjuvant or neoadjuvant setting.

This, Miller underlined, is where the ocular toxicity with these ADCs “may be much more prohibitive.”

As reported by Medscape Medical News, the drug was associated with a significant increase in progression-free survival over physician’s choice of therapy. However, 78% of patients in the ADC group experienced at least one treatment-emergent ocular toxicity adverse event vs 29.2% of those in the control group.

Moreover, grade 3 or high ocular toxicity events were reported by 21% of patients in the experimental group compared with none of those who received physician’s choice.

 

Ocular Toxicities Seen on Ocular Surface

Ocular toxicities with these drugs are “not necessarily a new thing,” said Joann J. Kang, MD, director, Cornea and Refractive Surgery, and associate professor of ophthalmology at Albert Einstein College of Medicine, Montefiore Medical Center, Bronx, New York.

“But what we’re seeing with certain ADCs is a lot of ocular toxicity, especially on the ocular surface,” with the degree toxicity varying depending on the ADC in question. “It’s definitely a real concern.”

Kang noted that separate from T-Duo, certain ADCs already come with black box warnings for ocular toxicity, including:

• Belantamab mafodotin (Blenrep) — approved for relapsed or refractory multiple myeloma and carries a warning specifically for keratopathy.
• Tisotumab vedotin (Tivdak) — indicated for recurrent or metastatic cervical cancer and can cause changes in the corneal epithelium and conjunctiva.
• Mirvetuximab soravtansine (Elahere) — used to treat folate receptor (FR) alpha–positive ovarian, fallopian tube, and peritoneal cancers and can lead to keratopathy, blurred vision, and dry eyes.

Indeed, the American Academy of Ophthalmology 2024 annual meeting saw research presented indicating that mirvetuximab was associated with moderate or severe corneal toxicity in 47% of patients treated for primary gynecologic malignancies.

As reported by Medscape Medical News, the study, by researchers at Byers Eye Institute of Stanford University in Stanford, California, was a retrospective analysis of 36 eyes of 18 women who received mirvetuximab for FR alpha–positive, platinum-resistant primary ovarian cancer.

 

What Are the Causes?

But why would a drug that is targeted specifically to a cancer tumor, thanks to the presence of a monoclonal antibody, cause off-target effects such as ocular toxicity?

Kathy D. Miller, MD, professor of oncology and medicine at Indiana University School of Medicine in Indianapolis, pointed out that they are targeted in a relative and not absolute sense, meaning that the antigen target may not be truly limited to the tumor cells.

There can also be “a lot of ways that you could get systemic toxicities,” she said.

For example, if the linker connecting the antibody and the chemotherapy payload breaks prematurely or is not stable, or if the drug leaches out into the tumor microenvironment and then is “picked up into the circulation, that can give you systemic toxicity,” she said.

In addition, the drug may, once it is in the tumor cells, be metabolized to an active metabolite that could, again, result in systemic exposure.

 

Side Effects Are Underappreciated and Distressing

Ocular toxicity remains underappreciated among oncologists prescribing these drugs. One reason is that it “did not get enough attention” in the initial clinical trial reports, Miller said she suspects.

Another potential reason for this is that “we’re not used to thinking about it because it’s not particularly common among the drugs that oncologists use frequently,” she added. Additionally, it tends to come up later during treatment, “so people have to be on therapy for some time before you start to see it.”

Nevertheless, Miller underlined that ocular toxicity “can be particularly distressing for patients, as it’s uncomfortable [and] can lead to scarring, so some of the vision issues can be permanent.”

“We often see in these situations that there are different types of ocular toxicities that present in different patients,” said Jane L. Meisel, MD, co-director, Breast Medical Oncology, Department of Hematology and Medical Oncology at Emory University School of Medicine in Atlanta.

“Corneal damage is pretty common, and patients can present with blurry vision, or dry eyes, or light sensitivity. And unlike some side effects, these are things that really impact people at every waking moment of their day.”

“So they’re pretty clinically significant side effects, even if they’re not life-threatening,” Meisel emphasized.

Miller suspects that more heavily pretreated patients may be more likely to experience ocular toxicity, as “there’s a much higher incidence of dry eyes in our patients than we recognize.”

She added: “We don’t usually ask about it, and we certainly don’t routinely do Schirmer’s tests,” which determine whether the eye produces enough tears to keep it moist.

 

Preventive Measures

For patients receiving tisotumab or mirvetuximab who experience ocular toxicity, Kang said the recommendation is to use steroid eye drops before, during, and after treatment with the ADC.

However, she noted that steroids have not been found to be useful in patients given belantamab, so clinicians have tried vasoconstrictor eye drops immediately prior to the infusion, as well as ocular cooling masks, which “are thought to help by reducing blood supply to the ocular areas.”

Other approaches to minimize ocular toxicity have included longer infusion times, so it’s “not so much of a hefty dose at one time,” Kang added.

She underlined that grade 2 and 3 ocular toxicities can lead to dose delays or dose modifications, and “usually by the time you get a grade 4 event, then you may need to discontinue the medication.”

This can have consequences for the patients because they are often “very sick, and this may be their third agent that they’re trying,” or it may be that their tumor is responding to a new treatment, but it has to be withheld because of an ocular toxicity.

“It can be incredibly frustrating for patients, and also for oncologists, and then for ophthalmologists,” Kang said.

 

Closer Collaboration Between Specialists Needed

What’s known about ocular side effects in patients taking ADCs underlines that there is a need for closer collaboration between oncologists and ophthalmologists.

“In oncology, especially as immunotherapies came to the forefront, our relationships with our endocrinology colleagues have become stronger because we’ve needed them to help us manage things like thyroid toxicity and pituitary issues related to immunotherapy,” Meisel said.

With toxicities that may be “very impactful for patient quality of life, like ocular toxicity, we will need to learn more about them and develop protocols for management, along with our ophthalmology colleagues, so that we can keep patients as comfortable as possible, while maximizing the efficacy of these drugs.”

Miller agreed, saying oncologists need to have “a conversation with a local ophthalmologist,” although she conceded that, in many areas, such specialists “are in short supply.”

The oncologist “not only needs to be aware” of and looking for ocular toxicity when using these ADCs but also needs to be thinking: “If I run into trouble here, who’s my ophthalmology backup? Are they familiar with this drug? And do we have a plan for the multispecialty management of patients who run into this toxicity?”

 

Setting Counts When Assessing Toxicities

But do all these considerations mean that ADCs’ potential ocular toxicity should give clinicians pause when considering whether to use these drugs?

“What my patients most want are drugs that work; that are effective in controlling their tumors,” Miller said.

“Every drug we use has potential toxicities, and which toxicities are most physically troublesome [or] are the greatest concern may vary from patient to patient, and it may vary a lot from patients with metastatic disease to those in the curative setting.”

She explained that “toxicities that might not be prohibitive at all in the metastatic setting [may] have to be a much bigger part of our considerations” when moving drugs into the adjuvant or neoadjuvant setting.

This, Miller underlined, is where the ocular toxicity with these ADCs “may be much more prohibitive.”

Despite being a targeted therapy, antibody-drug conjugates (ADCs) can cause significant off-target toxicity to the eyes of patients being treated for advanced multiple myeloma or cervical cancer, yet the risks remain relatively unknown, according to oncologists and ophthalmologists.

Such experts called for greater collaboration between oncologists and ophthalmologists, in interviews with Medscape Medical News.

In preparation for a future international treaty aimed at reducing plastic pollution, the French Parliamentary Office for the Evaluation of Scientific and Technological Choices presented the conclusions of a public hearing on the impact of plastics on various aspects of human health.

Increased Global Plastic Production

Philippe Bolo, a member of the French Democratic Party and the rapporteur for the public mission on the health impacts of plastics, spoke about the latest round of treaty negotiations, held from November 25 to December 1 in South Korea, attended by leading French and global experts about the impact of plastics on human health.

The hearing highlighted a sharp increase in plastic production. “It has doubled in the last 20 years and is expected to exceed 500 million tons in 2024,” Bolo said. This is about 60 kg per person. According to projections from the Organization for Economic Co-operation and Development, on its current trajectory, plastic production will reach 750 million tons by 2040 and surpass 1 billion tons before 2050, he said.

 

Minimal Plastic Waste Recycling

Around one third (32%) of plastics are used for packaging. “Therefore, most plastic production is still intended for single-use purposes,” he said. Plastic waste follows a similar growth trajectory, with volumes expected to rise from 360 million tons in 2020 to 617 million tons by 2040 unless action is taken. Very little of this waste is recycled, even in the most countries that are most advanced in terms of collection, sorting, and processing.

In France, for example, in 2018, only 0.6 million tons of the 3.6 million tons of plastic waste produced was truly recycled. This is less than one fifth (17%). Globally, less than 10% of plastic waste is recycled. In 2020, plastic waste that ended up in the environment represented 81 million tons, or 22% of the total. “Beyond waste, this leads to pollution by microplastics and nanoplastics, resulting from their fragmentation. All environments are affected: Seas, rivers, soils, air, and even living organisms,” Bolo said.

 

Methodological Challenges

However, measuring the impact of plastics on health faces methodological difficulties due to the wide variety of composition, size, and shape of plastics. Nevertheless, the French Standardization Association (Association Française de Normalisation) has conducted work to establish a characterization standard for microplastics in water, which serves as an international reference.

“It is also very difficult to know what we are ingesting,” Bolo said. “A study conducted in 2019 estimated that the average human absorbs 5 grams of plastics per week, the equivalent of a credit card.» Since then, other studies have revised this estimate downward, but no consensus has been reached.

A recent study across 109 countries, both industrialized and developing, found significant exposure, estimated at 500 mg/d, particularly in Southeast Asian countries, where it was due mainly to seafood consumption.

A study concluded that plastic water bottles contain 240,000 particles per liter, 90% of which are nanoplastics. These nanoparticles can pass through the intestinal barrier to enter the bloodstream and reach several organs including the heart, brain, and placenta, as well as the fetus.

 

Changes to the Microbiome

Microplastics also accumulate in organs. Thus, the amount of plastic in the lungs increases with age, suggesting that particles may persist in the body without being eliminated. The health consequences of this are still poorly understood, but exposure to plastics appears to cause changes in the composition of the intestinal microbiota. Pathobionts (commensal bacteria with harmful potential) have been found in both adults and children, which could contribute to dysbiosis of the gut microbiome. Furthermore, a decrease in butyrate, a short-chain fatty acid beneficial to health, has been observed in children’s intestines.

Inhaled nanoplastics may disrupt the mucociliary clearance mechanisms of the respiratory system. The toxicity of inhaled plastic particles was demonstrated as early as the 1970s among workers in the flocking industry. Some developed lung function impairments, shortness of breath, inflammation, fibrosis, and even lung cancer. Similar symptoms have been observed in workers in the textile and polyvinyl chloride industries.

A study published recently in The New England Journal of Medicine measured the amount of microplastics collected from carotid plaque of more than 300 patients who had undergone carotid endarterectomy for asymptomatic carotid artery disease. It found a 4.53 times higher risk for the primary endpoint, a composite of myocardial infarction, stroke, and all-cause mortality, among individuals with microplastics and nanoplastics in plaque compared with those without.

 

Health Affects High

The danger of plastics is also directly linked to the chemical substances they contain. A general scientific review looked at the health impacts of three chemicals used almost exclusively in plastics: Polybromodiphenyl ethers (PBDEs), used as flame retardants in textiles or electronics; bisphenol A (BPA), used in the lining of cans and bottles; and phthalates, particularly diethylhexyl phthalate (DEHP), used to make plastics more flexible.

The review highlighted strong epidemiological evidence linking fetal exposure to PBDEs during pregnancy to low birth weight and later exposure to delayed or impaired cognitive development in children and even a loss of IQ. Statistically significant evidence of disruption of thyroid function in adults was also found.

BPA is linked to genital malformations in female newborns exposed to BPA in utero, type 2 diabetes in adults, insulin resistance, and polycystic ovary syndrome in women. BPA exposure also increases the risk for obesity and hypertension in both children and adults, as well as the risk for cardiovascular disease in adults.

Finally, the review established links between exposure to DEHP and miscarriages, genital malformations in male newborns, delayed or impaired cognitive development in children, loss of IQ, delayed psychomotor development, early puberty in young girls, and endometriosis in young women. DEHP exposure also has multiple effects on cardiometabolic health, including insulin resistance, obesity, and elevated blood pressure.

The economic costs associated with the health impacts of these three substances have been estimated at $675 billion in the United States.

Bolo said that the solution to this plastic pollution is necessarily international. “We need an ambitious and legally binding treaty to reduce plastic production,” he said. “The damage is already done; we need to act to protect human health,” he concluded. The parliamentary office has made nine recommendations to the treaty negotiators.

The danger of plastics is also directly linked to the chemical substances they contain. A general scientific review looked at the health impacts of three chemicals used almost exclusively in plastics: Polybromodiphenyl ethers (PBDEs), used as flame retardants in textiles or electronics; bisphenol A (BPA), used in the lining of cans and bottles; and phthalates, particularly diethylhexyl phthalate (DEHP), used to make plastics more flexible.

The review highlighted strong epidemiological evidence linking fetal exposure to PBDEs during pregnancy to low birth weight and later exposure to delayed or impaired cognitive development in children and even a loss of IQ. Statistically significant evidence of disruption of thyroid function in adults was also found.

BPA is linked to genital malformations in female newborns exposed to BPA in utero, type 2 diabetes in adults, insulin resistance, and polycystic ovary syndrome in women. BPA exposure also increases the risk for obesity and hypertension in both children and adults, as well as the risk for cardiovascular disease in adults.

Finally, the review established links between exposure to DEHP and miscarriages, genital malformations in male newborns, delayed or impaired cognitive development in children, loss of IQ, delayed psychomotor development, early puberty in young girls, and endometriosis in young women. DEHP exposure also has multiple effects on cardiometabolic health, including insulin resistance, obesity, and elevated blood pressure.

The economic costs associated with the health impacts of these three substances have been estimated at $675 billion in the United States.

Bolo said that the solution to this plastic pollution is necessarily international. “We need an ambitious and legally binding treaty to reduce plastic production,” he said. “The damage is already done; we need to act to protect human health,” he concluded. The parliamentary office has made nine recommendations to the treaty negotiators.

TOPLINE:

Oral doxycycline (200 mg twice daily for 28 days) appears to be as effective as intravenous (IV) penicillin for the treatment of ocular syphilis for some patients with the condition.

METHODOLOGY:

• Researchers conducted a retrospective cohort study of ocular syphilis cases diagnosed from 2017 to 2023 in Los Angeles, analyzing 32 patients with a median age of 46 years (78% men).
• Patients treated before January 2022 received IV doxycycline, while those treated after that date were given the option to receive an oral form of the drug.
• A total of 16 patients received oral doxycycline (seven patients received only oral doxycycline; nine received a short course of parenteral penicillin followed by a full course of oral doxycycline); another 16 patients received a full course of IV penicillin.
• The analysis measured visual acuity (VA), ocular inflammation, and rapid plasma reagin (RPR).

TAKEAWAY:

• The doxycycline group had better median VA at both the initial presentation and the final follow-up than the penicillin group (VA, 0.44, 0.18; P = .04; VA, 1.0, 0.40; P = .03, respectively).
• Resolution of ocular inflammation showed no significant differences between the doxycycline and IV penicillin groups (P = .62 for both).
• All patients who had follow-up at 9 months demonstrated a fourfold decrease in RPR titers (four people in the oral doxycycline group and seven people in the IV penicillin group).

IN PRACTICE:

“We found that oral doxycycline for the treatment of ocular syphilis may be safe and effective in a selected subset of patients who completed an extended oral antibiotic regimen,” the study authors wrote. “Other studies have also demonstrated similar efficacy of oral therapy when compared with IV therapy. A fourfold decrease in RPR titers was considered an adequate serologic treatment response and corresponds with resolution of syphilis disease activity. This was observed in all patients with more than 9 months of follow-up. Long-term monitoring is recommended for those treated with doxycycline to ensure clinical and serologic response.”

SOURCE:

The study was led by Brian C. Toy, MD, of the Roski Eye Institute at the Keck School of Medicine at the University of Southern California in Los Angeles. It was published online in JAMA Network Open.

LIMITATIONS:

The study was retrospective in nature, used heterogeneous treatment methods, and lacked longitudinal RPR titers.

DISCLOSURES:

Toy served on physician advisory boards for Alimera, EyePoint, Bausch and Lomb, and Regeneron. No other disclosures were reported.

TOPLINE:

Adding camrelizumab to neoadjuvant chemotherapy increases pathological complete response rate to 56.8% vs 44.7% with placebo in early or locally advanced triple-negative breast cancer. The combination shows consistent benefits across patient subgroups with a manageable safety profile.

METHODOLOGY:

• A randomized, double-blind, phase 3 trial enrolled 441 females (median age, 48 years) with early or locally advanced triple-negative breast cancer from 40 hospitals in China between November 2020 and May 2023.
• Participants were randomized 1:1 to receive either camrelizumab 200 mg (n = 222) or placebo (n = 219) combined with chemotherapy every 2 weeks, with median follow-up period of 14.4 months.
• Treatment included nab-paclitaxel (100 mg/m²) plus carboplatin (area under curve, 1.5) on days 1, 8, and 15 in 28-day cycles for 16 weeks, followed by epirubicin (90 mg/m²) and cyclophosphamide (500 mg/m²) every 2 weeks for 8 weeks.
• The primary endpoint was pathological complete response, defined as no invasive tumor in breast and lymph nodes.

TAKEAWAY:

• Pathological complete response was achieved in 56.8% (95% CI, 50.0%-63.4%) of patients in the camrelizumab-chemotherapy group vs 44.7% (95% CI, 38.0%-51.6%) in the placebo-chemotherapy group (rate difference, 12.2%; 95% CI, 3.3%-21.2%; P = .004).
• Grade 3 or higher adverse events occurred in 89.2% of camrelizumab-chemotherapy group vs 83.1% in placebo-chemotherapy group, with serious adverse events in 34.7% vs 22.8%, respectively.
• Event-free survival rate at 18 months was 86.6% (95% CI, 79.9%-91.1%) with camrelizumab-chemotherapy vs 83.6% (95% CI, 76.2%-88.9%) with placebo-chemotherapy (hazard ratio [HR], 0.80; 95% CI, 0.46-1.42).
• Disease-free survival rate at 12 months reached 91.9% (95% CI, 85.5%-95.5%) with camrelizumab-chemotherapy compared with 87.8% (95% CI, 80.3%-92.6%) with placebo-chemotherapy (HR, 0.58; 95% CI, 0.27-1.24).

IN PRACTICE:

“The addition of camrelizumab to neoadjuvant chemotherapy significantly improved pathological complete response... The benefits of camrelizumab-chemotherapy with respect to pCR were generally consistent across subgroups,” wrote the authors of the study.

SOURCE:

The study was led by Zhi-Ming Shao, MD, Fudan University Shanghai Cancer Center in Shanghai, China. It was published online on December 13 in JAMA.

LIMITATIONS:

According to the authors, the study’s limitations include short follow-up duration preventing assessment of mature survival data and long-term safety profile, uncertainty about optimal duration of adjuvant camrelizumab treatment, small sample sizes in some subgroups warranting cautious interpretation, and potential limited generalizability as the study was conducted only in Chinese patients with triple-negative breast cancer.

DISCLOSURES:

The study was supported by Jiangsu Hengrui Pharmaceuticals. The authors and funder were involved in data collection, analysis, and interpretation and guaranteed the accuracy, completeness of the data, writing of the report, and the decision to submit the manuscript for publication.

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.”

This transcript has been edited for clarity. 

We often see urinary tract infections in primary care, so these guidelines for the prevention, diagnosis and management of urinary tract infection (UTI) are very helpful to reaffirm our knowledge in the areas where know what we’re doing and update our knowledge in areas of uncertainty. These guidelines are from a new group called the WikiGuidelines group. Ordinarily, I wouldn’t have considered reviewing one of these guidelines, but this one was published in JAMA Network Open. It is evidence based and covers the topic really well. 

Diagnosis. Order a urinalysis or a urine culture only if the patient is having symptoms of a UTI. This may seem obvious, but particularly among older individuals, in whom asymptomatic bacteriuria is very common and should not be treated, nonspecific symptoms such as just not feeling well for a day do not warrant obtaining a urinalysis and culture. With no clear way to distinguish between asymptomatic bacteriuria and a true UTI, the first step in making the diagnosis of a UTI accurately is ordering urine studies only in people who have a reasonable chance of having an infection.

The guideline suggests that the diagnosis of UTI should be primarily based on clinical symptoms. A urinalysis can provide further information, but the authors caution us against relying solely on the urinalysis. This is an incredibly important evidence-based recommendation. If you think about it, this supports the common practice of treating UTIs over the phone without having to see the patient or check a urinalysis. 

The rationale for this recommendation is that urinalysis is neither a sensitive nor specific test for UTI. The sensitivity of leukocyte esterase is only about 80%, and the specificity is even lower. For positive nitrite on urinalysis, the sensitivity is below 50%, meaning the test would be negative more than half the time when someone actually has a UTI. The specificity of urine nitrate is very high (more than 90%), so if the patient is nitrite positive, they clearly have a UTI. This means that a patient’s report of classic UTI symptoms — urinary burning, frequency, and urgency — is about as good if not a better indicator of a UTI than a urinalysis. 

The guidelines also say that in simple uncomplicated cystitis in healthy nonpregnant patients, routine urine cultures are not necessary. A fascinating meta-analysis in JAMA showed that, for women presenting to outpatient clinics with at least two symptoms of UTI and absence of vaginal discharge, there was a greater than 90% likelihood of having acute cystitis. A reminder here, however: If a woman is sexually active and at risk for sexually transmitted infections, then consider testing for STIs as well, because the symptoms of an STI can mimic those of a UTI.

Treatment. Treatment for UTI is usually empiric, with treatment initiated before the culture results are known and with cultures being done only for people with complicated infections, such as pyelonephritis, or with recurrent infections. Decisions about what to use for treatment can be influenced by local patterns of resistance and an individual’s risk factors for antimicrobial resistance. As a general rule, for uncomplicated cystitis, nitrofurantoin for 5 days is a reasonable first-line agent. Evidence of efficacy is good, and the risk for antimicrobial resistance is lower vs using antibiotics for other systemic infections. 

Other reasonable first-line agents for uncomplicated cystitis include trimethoprim-sulfamethoxazole (TMP-SMX) for 3 days; fosfomycin (oral) single dose; or a beta-lactam (most commonly a first generation cephalosporin), although evidence for duration is unclear. Also mentioned are two unfamiliar antibiotics: pivmecillinam (a beta-lactam agent recently approved by the Food and Drug Administration [FDA], given for 3 days) and gepotidacin (from a new class of antibiotic that is currently under FDA review). Fluoroquinolones should not usually be first-line agents unless other treatment options are not appropriate. 

It’s important to distinguish between uncomplicated cystitis and pyelonephritis. For pyelonephritis (infection of the upper urinary tract), the first decision has to do with setting for care, depending on how sick someone is, and the likelihood of gram-negative bacteremia — all of which help whether the patient needs to be hospitalized for intravenous antibiotics, or can be treated as an outpatient. Determine if they need to be admitted for intravenous antibiotics or whether they can be treated as an outpatient. For outpatient treatment of pyelonephritis, the guideline suggests that TMP-SMX or a first-generation cephalosporin are both reasonable first-line agents, with fluoroquinolones being a reasonable choice as well. Ceftriaxone is recommended for first-line therapy for patients who require intravenous treatment. 

People often forget that we can do a lot to prevent UTIs, particularly among women with recurrent UTIs. The prevention of UTIs has both nonpharmacologic and pharmacologic approaches.

Nonpharmacologic prevention. One nonpharmacologic strategy is increasing water intake. A randomized controlled trial in women with recurrent cystitis who drank less than 1.5 L of fluid a day showed that the women randomized to consume an additional 1.5 L of water daily had significantly reduced cystitis frequency — approximately 50%. Because this was the only randomized trial to show this effect, this is not a strong recommendation, but there is very little downside in healthy women, so increasing water intake is a reasonable recommendation.

Another commonly discussed intervention is the use of cranberry products. As it turns out, most prospective studies have shown that cranberry products can reduce the risk for symptomatic UTIs in women with recurrent UTI. 

Pharmacologic prevention. For postmenopausal women with recurrent UTI, topical vaginal estrogen has a strong base of evidence — more than 30 randomized trials — supporting its effectiveness in UTI: a 50%-90% reduction in the incidence of recurrent UTIs. Topical estrogen has minimal systemic absorption, and there are no concerning safety signals with respect to either thromboembolic disease or cancer (endometrial or breast). 

Methenamine hippurate is also recommended and is FDA-approved for prevention of UTIs. It works by releasing formaldehyde in the urine, leading to bacteriostasis, which is how it leads to a decrease in UTIs. Finally, postcoital or daily administration of TMP-SMX, nitrofurantoin, norfloxacin, and ciprofloxacin all have comparable efficacy for prophylaxis, with a meta-analysis showing a decrease in recurrence rate of approximately 85%. The guideline states that there is insufficient evidence to support the use of either probiotics or D-mannose to prevent UTIs.

We often see urinary tract infections in primary care, so these guidelines for the prevention, diagnosis and management of urinary tract infection (UTI) are very helpful to reaffirm our knowledge in the areas where know what we’re doing and update our knowledge in areas of uncertainty. These guidelines are from a new group called the WikiGuidelines group. Ordinarily, I wouldn’t have considered reviewing one of these guidelines, but this one was published in JAMA Network Open. It is evidence based and covers the topic really well. 

Diagnosis. Order a urinalysis or a urine culture only if the patient is having symptoms of a UTI. This may seem obvious, but particularly among older individuals, in whom asymptomatic bacteriuria is very common and should not be treated, nonspecific symptoms such as just not feeling well for a day do not warrant obtaining a urinalysis and culture. With no clear way to distinguish between asymptomatic bacteriuria and a true UTI, the first step in making the diagnosis of a UTI accurately is ordering urine studies only in people who have a reasonable chance of having an infection.

The guideline suggests that the diagnosis of UTI should be primarily based on clinical symptoms. A urinalysis can provide further information, but the authors caution us against relying solely on the urinalysis. This is an incredibly important evidence-based recommendation. If you think about it, this supports the common practice of treating UTIs over the phone without having to see the patient or check a urinalysis. 

The rationale for this recommendation is that urinalysis is neither a sensitive nor specific test for UTI. The sensitivity of leukocyte esterase is only about 80%, and the specificity is even lower. For positive nitrite on urinalysis, the sensitivity is below 50%, meaning the test would be negative more than half the time when someone actually has a UTI. The specificity of urine nitrate is very high (more than 90%), so if the patient is nitrite positive, they clearly have a UTI. This means that a patient’s report of classic UTI symptoms — urinary burning, frequency, and urgency — is about as good if not a better indicator of a UTI than a urinalysis. 

The guidelines also say that in simple uncomplicated cystitis in healthy nonpregnant patients, routine urine cultures are not necessary. A fascinating meta-analysis in JAMA showed that, for women presenting to outpatient clinics with at least two symptoms of UTI and absence of vaginal discharge, there was a greater than 90% likelihood of having acute cystitis.

Vaccines recommended by the Advisory Committee on Immunization Practices (ACIP) offer important protection against severe illness for pregnant people and their babies.¹ However, vaccination coverage estimates among pregnant people remain suboptimal.^2-5 Additionally, some measures indicate that vaccine hesitancy among pregnant people is increasing; for example, 17.5% of surveyed pregnant women reported being very hesitant about influenza vaccination during pregnancy in 2019-2020, compared with 24.7% in 2022-2023.⁶As fall and winter virus season continues, consider opportunities for you and your staff to help communicate the importance of prenatal vaccination to pregnant patients in your care. Explore updated provider toolkits and prenatal vaccination patient education resources, including fact sheets, social media assets, posters, and short videos on respiratory syncytial virus (RSV), Tdap, COVID-19, influenza, and hepatitis B.

In an interview, CDC’s Haben Debessai, MD, an adjunct instructor in obstetrics and gynecology at Emory School of Medicine, Atlanta, Georgia, contextualizes the data to help healthcare professionals communicate effectively with their pregnant patients. 

 

What can practitioners communicate to patients about why it is important to get vaccinated during their pregnancy?

When communicating with their patients, practitioners can consider opportunities to discuss how vaccines work during pregnancy, emphasizing that prenatal vaccinations are beneficial for both the pregnant person and the fetus. It can be helpful to educate patients on how a pregnant person’s immune system can develop antibodies that will then pass to the fetus during the pregnancy and confer protection during the infant’s early months of life — when they are highly susceptible to illnesses that can be severe, such as RSV-associated lower respiratory tract infections. It can also be useful to discuss pregnancy’s impact on the immune system, which contributes to pregnant people being at higher risk for severe illness from infections like COVID-19 and flu, if contracted. The outcomes of severe illness can be dire for both the pregnant person and their pregnancy, which is why vaccination is the best mitigation option. It can also be beneficial to share with patients that some vaccines, like RSV and Tdap, are specifically for neonatal benefit, which could help patients understand why some vaccines are recommended at a specific gestational age and in each pregnancy or subsequent pregnancies. 

What is known about pregnant populations that experience disparities in vaccination coverage? 

While vaccination coverage among pregnant people is suboptimal, coverage estimates are often lowest among Black pregnant people, some of whom report experiencing mistreatment and discrimination during pregnancy and delivery.⁷ It is important to recognize that there are many intersecting factors that may impact vaccination coverage. Systemic and structural factors may prohibit some patient populations from accessing vaccinations (eg, transportation barriers, difficulty accessing adequate healthcare for those on government assistance, language barriers). To be responsive to the intersectional lived realities of each of these communities, the medical and public health community continually strives to increase trustworthiness, which can lead to increased uptake of vaccinations in these populations.
