Syphilis and chlamydia infections were reduced by half among men who have sex with men and transgender women 1 year after San Francisco rolled out doxycycline postexposure prophylaxis (doxy-PEP), according to data presented at the Conference on Retroviruses and Opportunistic Infections (CROI) this week.

After a clinical trial showed that doxy-PEP taken after sex reduced the chance of acquiring syphilis, gonorrhea, and chlamydia by about two-thirds, the San Francisco Department of Public Health released the first guidelines in the country in October 2022. 

The guidelines recommend that a person take two 100-mg pills of doxycycline ideally in the 24 hours after but no more than 72 hours after condomless sex. So far, more than 3700 people in San Francisco have been prescribed doxy-PEP, reports Stephanie Cohen, MD, director of HIV and sexually transmitted infection (STI) prevention in the Disease Prevention and Control Branch of Public Health.

Dr. Cohen and her colleagues spent a year monitoring the uptake of doxy-PEP and used a computer model to predict what the rates of sexually transmitted infection would have been without doxy-PEP. 

In November 2023, 13 months after the guidelines were introduced, they found that monthly chlamydia and early syphilis infections were 50% and 51% lower, respectively, than what was predicted by the model.
 

Fewer Infections

The drop in infections is having a tangible effect on patients in San Francisco, and many clinicians are noting that they are seeing far fewer positive tests. “The results that we’re seeing on a city-wide level are absolutely being experienced by individual providers and patients,” Dr. Cohen said.

However, the analysis showed no effect on rates of gonorrhea. It’s not clear why, although Dr. Cohen points out that doxy-PEP was less effective against gonorrhea in the clinical trial. And “there could be other factors in play,” she added. “Adherence might matter more, or it could be affected by the prevalence of tetracycline resistance in the community.”

With rates of STIs, particularly syphilis, quickly rising in recent years, healthcare providers have been scrambling to find effective interventions. So far, doxy-PEP has shown the most promise. “We’ve known for a while that all of the strategies we’ve been employing don’t seem to be working,” noted Chase Cannon, MD, an infectious disease specialist at the University of Washington in Seattle. “That’s why doxy-PEP is important. We haven’t had anything that can deflect the curve in a long time.”
 

What About the Side Effects?

Some concerns remain, however, about the widespread prophylactic use of antibiotics. There are no long-term safety data on the potential side effects of doxy-PEP, and there is still a lot of stigma around interventions that allow people to have sex the way they want, said Dr. Cannon.

But perhaps, the biggest concern is that doxy-PEP could contribute to antibiotic resistance. Those fears are not misplaced, Dr. Cannon added. The results of one study, presented in a poster at CROI, showed that stool samples from people prescribed doxy-PEP had elevated levels of bacterial genes that can confer resistance to tetracyclines, the class of antibiotics to which doxycycline belongs. There was no change in resistance to other classes of antibiotics and no difference in bacterial diversity over the 6 months of the study.

Dr. Cannon cautioned, however, that we can’t extrapolate these results to clinical outcomes. “We can look for signals [of resistance], but we don’t know if this means someone will fail therapy for chlamydia or syphilis,” he said.

There are still many challenges to overcome before doxy-PEP can be rolled out widely, Dr. Cohen explained. There is a lack of consensus among healthcare professionals about who should be offered doxy-PEP. The clinical trial results and the San Fransisco guidelines only apply to men who have sex with men and to transgender women.

Some clinicians argue that the intervention should be provided to a broader population, whereas others want to see more research to ensure that unnecessary antibiotic use is minimized.

So far just one study has tested doxy-PEP in another population — in women in Kenya — and it was found to not be effective. But the data suggest that adherence to the protocol was poor in that study, so the results may not be reliable, Dr. Cohen said.

“We need effective prevention tools for all genders, especially cis women who bear most of the morbidity,” she said. “It stands to reason that this should work for them, but without high-quality evidence, there is insufficient information to make a recommendation for cis women.”

The US Centers for Disease Control and Prevention is currently reviewing public and expert comments and refining final guidelines for release in the coming months, which should alleviate some of the uncertainty. “Many providers are waiting for that guidance before they will feel confident moving forward,” Dr. Cohen noted.

But despite the risks and uncertainty, doxy-PEP looks set to be a major part of the fight against STIs going forward. “Doxy-PEP is essential for us as a nation to be dealing with the syphilis epidemic,” Carl Dieffenbach, PhD, director of the Division of AIDS at the National Institute of Allergy and Infectious Disease, said in a video introduction to CROI.

Posttraumatic headache (PTH) is associated with an increase in iron accumulation in certain brain regions , notably those involved in the pain network, early research shows.

Investigators found positive correlations between iron accumulation and headache frequency, number of lifetime mild traumatic brain injuries (mTBIs), and time since last mTBI.

The findings come on the heels of previous research showing patients with iron accumulation in certain brain regions don’t respond as well to treatment, study investigator, Simona Nikolova, PhD, assistant professor of neurology, Mayo Clinic, Phoenix, Arizona, told this news organization.

“This is really important, and doctors need to be aware of it. If you have a patient who is not responding to treatment, then you know what to look at,” she said. 

The findings (Abstract #3379) will be presented on April 15 at the American Academy of Neurology (AAN) 2024 Annual Meeting. 
 

Dose Effect

The study included 60 people with acute PTH due to mTBI. Most were White, and almost half had sustained a concussion due to a fall, with about 30% injured in a vehicle accident and a smaller number injured during a fight.

The mean number of lifetime mTBIs was 2.4, although participants had sustained as many as five or six and as few as one. The mean time from the most recent mTBI was 25 days, and the mean score on the Sport Concussion Assessment Tool (SCAT), which measures postconcussion symptom severity, was 29.

Most in the mTBI group (43) had migraine or probable migraine, and 14 had tension-type headaches. Mean headache frequency was 81%.

Researchers matched these patients with 60 controls without concussion or headache. Because iron accumulation is age-related, they tried to eliminate this covariant by pairing each participant with mTBI with an age- and sex-matched control.

All participants underwent a type of brain MRI known as T2* weighted sequence that can identify brain iron accumulation, a marker of neural injury. 

Investigators found that the PTH group had significantly higher levels of iron accumulation in several areas of the brain, most of which are part of a “pain network” that includes about 63 areas of the brain, Dr. Nikolova said.

The study wasn’t designed to determine how much more iron accumulation mTBI patients had vs controls. 

“We can’t say it was twice as much or three times as much; we can only say it was significant. Measuring concentrations in PTH patients and comparing that with controls is something we haven’t don’t yet,” said Dr. Nikolova.

Areas of the brain with increased iron accumulation, included the periaqueductal gray (PAG), anterior cingulated cortex, and supramarginal gyrus. 

Research suggests patients with migraine who have elevated levels of iron in the PAG have a poorer response to botulinum toxin treatment. An earlier study by the same team showed a poorer response to the calcitonin gene-related peptide inhibitor erenumab in migraine patients with elevated iron in the PAG.

Researchers discovered that those with more lifetime TBIs had higher iron accumulation in the right gyrus rectus and right putamen vs those with fewer injuries and that headache frequency was associated with iron accumulation in the posterior corona radiata, bilateral temporal, right frontal, bilateral supplemental motor area, left fusiform, right hippocampus, sagittal striatum, and left cerebellum.
 

Surprising Result

The investigators also found a link between time since the most recent mTBI and iron accumulation in the bilateral temporal, right hippocampus, posterior and superior corona radiata, bilateral thalamus, right precuneus and cuneus, right lingual, and right cerebellum. 

“The more time that passed since the concussion occurred, the more likely that people had higher iron levels,” said Dr. Nikolova.

It’s perhaps to be expected that the length of time since injury is linked to iron accumulation in the brain as iron accumulates over time. But even those whose injury was relatively recent had higher amounts of iron, which Dr. Nikolova said was “surprising.”

“We thought iron accumulates over time so we were thinking maybe we should be doing a longitudinal study to see what happens, but we see definite iron accumulation due to injury shortly after the injury,” she said.

There was no association between iron accumulation and symptom severity as measured by SCAT scores.
 

Questions Remain

It’s unclear why iron accumulates after an injury or what the ramifications are of this accumulation, Dr. Nikolova noted. 

The imaging used in the study doesn’t distinguish between “bound” iron found after a hemorrhage and “free” iron in the brain. The free iron type has been shown to be increased after TBI and is “the stuff you should be afraid of,” Dr. Nikolova said.

Iron’s role in the metabolic process is important, but must be closely regulated, she said. Even a small accumulation can lead to oxidative stress.

Researchers are investigating whether the findings would be similar in mTBI but no headache and want to increase the number of study participants. A larger, more diverse sample would allow them to probe other questions, including whether iron accumulation is different in men and women. More data could also eventually lead to iron accumulation becoming a biomarker for concussion and PTH, Dr. Nikolova said.

“If you know a certain person has that biomarker, you might be able to administer a drug or some therapeutic procedure to prevent that iron from continuing to accumulate in the brain.”

Chelation drugs and other therapies may clear iron from the body but not necessarily from the brain. 

Commenting on the study for this news organization, Frank Conidi, MD, director, Florida Center for Headache and Sports Neurology, Port St. Lucie , said that the study supports the hypothesis that concussion “is not a benign process for the brain, and the cumulative effect of repetitive head injury can result in permanent brain injury.”

He said that he found the accumulation of iron in cortical structures particularly interesting. This, he said, differs from most current research that suggests head trauma mainly results in damage to white matter tracts.

He prefers the term “concussion” over “mild traumatic brain injury” which was used in the study. “Recent guidelines, including some that I’ve been involved with, have defined mild traumatic brain injury as a more permanent process,” he said.

The study was supported by the US Department of Defense and National Institutes of Health. No relevant conflicts of interest were disclosed.

TOPLINE:

Drinking 2 L or more of artificially sweetened drinks per week was associated with a 20% increased risk for atrial fibrillation (AF) in a new observational study.

METHODOLOGY:

• The population-based cohort study looked at the associations of sugar-sweetened beverages, artificial sweetened beverages, and pure fruit juice consumption with the risk for incident AF and evaluated whether genetic susceptibility modifies these associations.
• The authors analyzed data from the UK Biobank on 201,856 participants who were free of baseline AF, had genetic data available, and completed a 24-hour diet questionnaire. The diagnosis of AF was obtained by linkage from primary care, hospital inpatient, and death register records.
• The results were adjusted for a wide range of potential confounders including age, sex, ethnicity, education level, socioeconomic status, smoking, alcohol consumption, physical activity level, sleep duration, body mass index, blood pressure, kidney function, sleep apnea, coronary heart disease, diabetes, and the use of lipid-lowering or antihypertensive medication.

TAKEAWAY:

• During a median follow-up of 9.9 years, 9362 incident AF cases were documented.
• Compared with nonconsumers, individuals who consumed more than 2 L per week of artificially sweetened beverages had a 20% increased risk of developing AF (hazard ratio [HR], 1.20; 95% CI, 1.10-1.31).
• Those who drank more than 2 L per week of sugar-sweetened beverages had a 10% increased risk for AF (HR, 1.10; 95% CI, 1.01-1.20).
• Consumption of 1 L or less per week of pure fruit juice was associated with an 8% lower risk of developing AF (HR, 0.92; 95% CI, 0.87-0.97).
• The associations persisted after adjustment for genetic susceptibility for AF.

IN PRACTICE:

The study authors concluded that this study does not demonstrate that consumption of sugar-sweetened or artificially sweetened beverages alters AF risk but rather that the consumption of these drinks may predict AF risk beyond traditional risk factors. They added that intervention studies and basic research are warranted to confirm whether the observed associations are causal. Commenting on the study, Duane Mellor, MD, registered dietitian at Aston University, Birmingham, England, said it is unclear if the observations in this study are a chance finding as there is a lack of a clear biological link. Naveed Sattar, MD, professor of metabolic medicine at the University of Glasgow, Glasgow, Scotland, added that although the authors tried to adjust for many factors, there is a strong chance that other behavioral aspects linked to beverage choice could be more relevant as a cause of AF rather than the drinks themselves. Tom Sanders, MD, professor emeritus of nutrition and dietetics, King’s College London, London, England, pointed out that as this is the first study that has reported such an effect with artificially sweetened drinks, the finding needs replication before any conclusions can be drawn. “It remains good dietary advice to recommend the consumption of low-calorie artificially sweetened drink in place of sugar-sweetened drinks and alcohol,” he added.

The study, led by Ying Sun, MD, Shanghai Jiao Tong University School of Medicine, Shanghai, China, was published online in Circulation: Arrhythmia and Electrophysiology.

LIMITATIONS:

The consumption of beverages was self-reported and based on only five separate single-day food intake recalls which were taken over the first 3 years of the study, which was extrapolated to estimate weekly intake. The researchers could not tell whether the sugar-sweetened and artificially sweetened drinks were caffeinated and could not rule out residual confounding by other unmeasured or unknown factors.

Breast cancer-specific mortality risk in men with hormone receptor–positive breast cancer persists for at least 20 years, but patterns of breast cancer–specific mortality (BCSM) are distinct from those in women, a new study finds.

Previous studies in women with hormone receptor–positive (HR+) breast cancer have shown a risk of distant recurrence and death for at least 20 years after diagnosis, but data for men are limited, wrote Julieta Leone, MD, of the Dana Farber Cancer Institute, Boston, and colleagues.
 

What is Known About Hormone Receptor–Positive Breast Cancer Mortality in Men vs. Women?

Invasive breast cancer in men is rare and consequently understudied, the researchers wrote. Previous studies of BCSM in men with more than 5 years’ follow-up consist mainly of case series at single institutions, the researchers wrote in JAMA Oncology (2024 Feb 29. doi: 10.1001/jamaoncol.2023.7194).

“We believed it would be important to study this issue to help inform the management of men with breast cancer,” corresponding author, José P. Leone, MD, said in an interview.

In 2021, Dr. J.P. Leone and colleagues published a study in Breast Cancer Research and Treatment that examined the 20-year risk of BCSM in women that included more than 36,000 individuals who had survived for 5 years, with a median of 14 years’ follow-up.

In that study of women, the BCSM risk at 20 years was significantly higher for those with HR-negative tumors, but the risk was still elevated for both types. Patients with stage IIIC HR-positive disease had four times the risk of BCSM over 20 years and those with stage IIIC HR-negative disease had seven times the risk of BCSM over 20 years compared with the risk of death not related to breast cancer, the researchers wrote.

Another study of nearly 2,400 men with breast cancer (mainly HR+) by Dr. J.P. Leone and colleagues showed that cancer stage, tumor subtype, and race were associated with overall survival and breast cancer-specific survival.
 

What Does the New Study Add?

The current study included 2,836 men diagnosed with stage I to stage III HR+ breast cancer between 1990 and 2008, using data from the Surveillance, Epidemiology, and End Results (SEER) database.

“We found that in men with breast cancer, the risk of breast cancer mortality persists for at least 20 years and that [the risk] depends on traditional clinicopathologic factors, such as age, tumor size, nodal status and tumor grade,” Dr. J.P. Leone said in an interview.

“The prolonged risk [of breast-cancer specific mortality] over 20 years that we observed in our study is similar to that previously reported in women; however, the kinetics of the risk over the 20-year period appears different in men,” he emphasized.

The men in the study, especially those with a higher stage of disease, appeared to have a bimodal distribution of the BRCA mortality risk, he said.

Two peaks were identified, he explained; an early peak in mortality risk at approximately 4 years from diagnosis and another at approximately 11 years after diagnosis.

Although women with breast cancer had a prolonged risk of breast cancer mortality, “the kinetics of the risk does not include 2 peaks, even in women with higher stage of disease.” In women with higher stage breast cancer, the peak mortality risk occurs approximately 5 years after diagnosis, he said.

The reasons for the later peak in men remain unclear, the researchers wrote in the study, but possible explanations include nonadherence to endocrine therapy, differences in tumor biologic factors, and differences in the tumor microenvironment between men and women, they noted, in the discussion section.
 

What Drives the Risk?

Key factors for breast cancer-specific mortality were age, tumor stage, and tumor grade.

The cumulative 20-year risk of BCSM in the current study was 12.4%, 26.2%, and 46.0% for stage I, II, and III, respectively. The adjusted BCSM risk was increased in patients younger than 50 years, those with grade II or III/IV tumors, and those with stage II or III disease.
 

What Are the Limitations?

The current study by Leone and colleagues was limited by the relatively small subgroup sample of men with stage III and N3 disease, lack of data on the use of systemic therapies, and lack of data on human epidermal growth factor receptor 2 gene (ERBB2), the researchers wrote. However, the long-term follow-up strengthened the results, and the study is the first known to assess 20-year BCSM risk in men with nonmetastatic HR+ breast cancer.

What Do Oncologists Need to Know About the Study?

The study findings indicate that the risk of breast cancer mortality persists for 20 years in men with hormone receptor–positive breast cancer, Dr. J.P. Leone said in an interview. As in women, the risk depends on traditional clinicopathologic factors, he noted.

“However, the kinetics of that risk appears to be different between men and women. In order to reduce the breast cancer mortality risk in men with hormone receptor–positive breast cancer, it will be important for men to consider the benefits of the treatment options that may be indicated for their specific situation,” he said.

“I think early detection is also very important,” he emphasized. To that end, increased awareness of the possibility for breast cancer in men, as well as prompt intervention when breast cancer is suspected, will help to improve early detection when the risk of breast cancer mortality is lower, he added.
 

What Are the Next Steps for Research?

“I think our study underscores the need for additional research to improve our adjuvant therapy options in both men and women with hormone receptor-positive breast cancer, to reduce the risk of long-term mortality,” he said.

The study received no outside funding. Lead author Julieta Leone had no financial conflicts to disclose. Dr. José P. Leone disclosed receiving institutional grants from Kazia Therapeutics and Seagen unrelated to the current study.

Hospital mergers and acquisitions continue to garner intense scrutiny from lawmakers, with pressure likely to hold steady following the recent announcement of new antitrust guidelines and state and federal investigations into potential healthcare monopolies.

In December, the US Department of Justice (DOJ) and the Federal Trade Commission (FTC) released updated guidelines outlining the factors they consider when determining if a merger illegally monopolizes a local healthcare market or jeopardizes access to critical healthcare services.

Last week, the DOJ also announced a UnitedHealth Group antitrust probe, just months after the healthcare conglomerate’s workforce numbers indicated it is now affiliated with or employs 10% of the US physician workforce.

While the impact of the latest guidelines is yet to be seen, concerns over healthcare market consolidation are not new. Over the past two decades, mergers have attracted attention for contributing to a decline in independent hospitals, said Rachel M. Werner, MD, PhD, executive director of the Leonard Davis Institute of Health Economics at the University of Pennsylvania, Philadelphia, Pennsylvania.

“At this point, most hospitals are operating in a pretty concentrated market,” she said.

Here are five things to know about the current state of hospital mergers.

1. Record-Breaking Merger Enforcements

The DOJ and FTC reported the highest level of enforcement activity in over 20 years in fiscal year 2022 — the latest available data. Together, the agencies filed 50 merger enforcement actions and brought a record-breaking number of merger enforcement challenges, resulting in 11 approved actions, the restructuring or abandonment of seven mergers, and six business deals entering litigation.

Included in those statistics was a proposed merger between the two largest health systems in Rhode Island, Lifespan and Care New England Health System, which was abandoned after the FTC and the state Attorney General took steps to block it. the HCA branch in Utah Healthcare abandoned plans for to acquire five Salt Lake City area hospitals from competitor Steward Health Care System, as did RWJBarnabas Health after exploring a merger with Saint Peter's Healthcare System in New Jersey.

2. New Antitrust Guidelines Consider Labor Market

The new guidelines notably focus on labor competition, said Jody Boudreault, JD, attorney and chair of the Antitrust Life Sciences and Healthcare Group at Baker Botts law firm in Washington, DC. Health professionals typically have more employment opportunities in an urban area, unless hindered by restrictive noncompete agreements, and fewer options in rural settings.

In the Lifespan merger that fell through, Ms. Boudreault said that the newly created hospital system would have employed two thirds of Rhode Island's full-time nurses, limiting opportunities for local employment elsewhere.

“Going forward, I would expect federal authorities to review not only the competitive impact of the hospitals merging but also the competitive impact of the physician, and especially nursing, workforce,” she said.

FTC Chair Lina M. Khan noted similar labor market concerns.

In a statement to Congress, she said that hospital consolidation reduces options for employees, who fear “being blacklisted from further hiring in a system that controls many of the hospitals in the area” and “makes workers afraid to file complaints, organize their workplace, or leave before the end of a contract.”

3. Mergers Can Drive Care Costs Higher

When hospital markets become less competitive, the cost of care often increases. In Indiana, inpatient prices rose 13% in hospitals that merged. Another study found that prices at monopoly hospitals are 12% higher than in markets with four or more rivals. Even cross-market mergers, when hospitals in different geographic locations combine, can drive prices higher.

Dr. Werner told this news organization that more significant price hikes of 20-30% aren’t unheard of, with reimbursements by some commercial insurance companies rising as much as 50%. “That’s the direct price that the insurers pay, but the burden of those higher prices ultimately falls on patients through higher premiums,” she said.

Still, the American Hospital Association (AHA) says that mergers and acquisitions can significantly lower annual operating expenses per admission and reduce inpatient readmission rates and mortality measures. In comments to the FTC, the AHA stated that mergers could provide a lifeline for rural and community hospitals struggling with shrinking payer reimbursement and rising labor and supply costs. The business arrangements also could ensure these communities maintain continuity of care.

Although a cross-market merger may initially benefit cash-strapped rural hospitals, Dr. Werner urged caution.

“In the long run, it’s not clear that it is good for patients because we start to see decreased access to some types of service, like labor and delivery, which are services needed in rural markets,” she said.

4. Mergers to Watch in 2024

Ms. Boudreault, who represented RWJBarnabas in the abandoned Saint Peter’s transaction, says the courts widely accepted the old merger guidelines, and it will take time to see how the new measures are interpreted. “The guidelines don’t yet have the force of law, but they can be persuasive to a court.”

Looking ahead, she is watching how Steward Health Care navigates its impending financial collapse. The nation’s largest private for-profit health system was previously owned by private equity firm Cerberus Capital Management and includes nine Massachusetts hospitals plus entities in at least seven other states.

Ms. Boudreault also plans to monitor Jefferson Health’s intent to merge with Lehigh Valley Health Network. “It’s a pretty big deal because they would become a 30-hospital system,” said Ms. Boudreault. The newly formed network would become the largest employer in Philadelphia.

5. Merger and Acquisition Reversals Unlikely

Dr. Werner said that mergers and acquisitions are complicated business moves that are nearly impossible to undo once approved, so it makes sense for agencies to continue to evaluate them closely.

“The costs of healthcare are borne by us as a society,” she said. “We’re going to have to live with the ill effects of a consolidated market once we let hospitals merge, so they deserve additional scrutiny.”

Hospital mergers and acquisitions continue to garner intense scrutiny from lawmakers, with pressure likely to hold steady following the recent announcement of new antitrust guidelines and state and federal investigations into potential healthcare monopolies.

In December, the US Department of Justice (DOJ) and the Federal Trade Commission (FTC) released updated guidelines outlining the factors they consider when determining if a merger illegally monopolizes a local healthcare market or jeopardizes access to critical healthcare services.

Last week, the DOJ also announced a UnitedHealth Group antitrust probe, just months after the healthcare conglomerate’s workforce numbers indicated it is now affiliated with or employs 10% of the US physician workforce.

While the impact of the latest guidelines is yet to be seen, concerns over healthcare market consolidation are not new. Over the past two decades, mergers have attracted attention for contributing to a decline in independent hospitals, said Rachel M. Werner, MD, PhD, executive director of the Leonard Davis Institute of Health Economics at the University of Pennsylvania, Philadelphia, Pennsylvania.

“At this point, most hospitals are operating in a pretty concentrated market,” she said.

Here are five things to know about the current state of hospital mergers.

1. Record-Breaking Merger Enforcements

The DOJ and FTC reported the highest level of enforcement activity in over 20 years in fiscal year 2022 — the latest available data. Together, the agencies filed 50 merger enforcement actions and brought a record-breaking number of merger enforcement challenges, resulting in 11 approved actions, the restructuring or abandonment of seven mergers, and six business deals entering litigation.

Included in those statistics was a proposed merger between the two largest health systems in Rhode Island, Lifespan and Care New England Health System, which was abandoned after the FTC and the state Attorney General took steps to block it. the HCA branch in Utah Healthcare abandoned plans for to acquire five Salt Lake City area hospitals from competitor Steward Health Care System, as did RWJBarnabas Health after exploring a merger with Saint Peter's Healthcare System in New Jersey.

2. New Antitrust Guidelines Consider Labor Market

The new guidelines notably focus on labor competition, said Jody Boudreault, JD, attorney and chair of the Antitrust Life Sciences and Healthcare Group at Baker Botts law firm in Washington, DC. Health professionals typically have more employment opportunities in an urban area, unless hindered by restrictive noncompete agreements, and fewer options in rural settings.

In the Lifespan merger that fell through, Ms. Boudreault said that the newly created hospital system would have employed two thirds of Rhode Island's full-time nurses, limiting opportunities for local employment elsewhere.

“Going forward, I would expect federal authorities to review not only the competitive impact of the hospitals merging but also the competitive impact of the physician, and especially nursing, workforce,” she said.

FTC Chair Lina M. Khan noted similar labor market concerns.

In a statement to Congress, she said that hospital consolidation reduces options for employees, who fear “being blacklisted from further hiring in a system that controls many of the hospitals in the area” and “makes workers afraid to file complaints, organize their workplace, or leave before the end of a contract.”

3. Mergers Can Drive Care Costs Higher

When hospital markets become less competitive, the cost of care often increases. In Indiana, inpatient prices rose 13% in hospitals that merged. Another study found that prices at monopoly hospitals are 12% higher than in markets with four or more rivals. Even cross-market mergers, when hospitals in different geographic locations combine, can drive prices higher.

Dr. Werner told this news organization that more significant price hikes of 20-30% aren’t unheard of, with reimbursements by some commercial insurance companies rising as much as 50%. “That’s the direct price that the insurers pay, but the burden of those higher prices ultimately falls on patients through higher premiums,” she said.

Still, the American Hospital Association (AHA) says that mergers and acquisitions can significantly lower annual operating expenses per admission and reduce inpatient readmission rates and mortality measures. In comments to the FTC, the AHA stated that mergers could provide a lifeline for rural and community hospitals struggling with shrinking payer reimbursement and rising labor and supply costs. The business arrangements also could ensure these communities maintain continuity of care.

Although a cross-market merger may initially benefit cash-strapped rural hospitals, Dr. Werner urged caution.

“In the long run, it’s not clear that it is good for patients because we start to see decreased access to some types of service, like labor and delivery, which are services needed in rural markets,” she said.

4. Mergers to Watch in 2024

Ms. Boudreault, who represented RWJBarnabas in the abandoned Saint Peter’s transaction, says the courts widely accepted the old merger guidelines, and it will take time to see how the new measures are interpreted. “The guidelines don’t yet have the force of law, but they can be persuasive to a court.”

Looking ahead, she is watching how Steward Health Care navigates its impending financial collapse. The nation’s largest private for-profit health system was previously owned by private equity firm Cerberus Capital Management and includes nine Massachusetts hospitals plus entities in at least seven other states.

Ms. Boudreault also plans to monitor Jefferson Health’s intent to merge with Lehigh Valley Health Network. “It’s a pretty big deal because they would become a 30-hospital system,” said Ms. Boudreault. The newly formed network would become the largest employer in Philadelphia.

While TikTok overflows with images of influencers making “adrenal cocktails” to combat what they call adrenal fatigue, the Endocrine Society says “no scientific proof exists to support adrenal fatigue as a true medical condition.”

Even before influencers began touting it on social media, a 2016 systematic review concluded that there is “no substantiation that adrenal fatigue” is an actual medical condition. Therefore, adrenal fatigue is still a myth.

Lynette Nieman, MD, Senior Investigator and Chief of the Endocrinology Consultation Service at the National Institutes of Health Clinical Center, Bethesda, Maryland, concurs.

“There is no scientific evidence that adrenal fatigue exists or causes [general] fatigue, depression, or the many common symptoms that are said to result from this condition,” she told this news organization via email.

Still, the term has gained currency among not only social media influencers who blame it for everything from cortisol surges to estrogen imbalances but also functional and integrative medical practitioners as an explanation for chronic dysfunction related to stress. 
 

Adrenal Fatigue, Burnout, or Adrenal Insufficiency?

Rather than “adrenal fatigue,” Marcelo Campos, MD, a primary care doctor at Atrius Health, said he prefers the medical term “burnout.”

Use of “burnout” shifts attention to the brain’s role in stress-related chronic dysfunction rather than the adrenal glands, said Dr. Campos, who also teaches at Harvard Medical School, Cambridge, Massachusetts.

More specifically still, the focuses might shift to the stress-response via the hypothalamic-pituitary-adrenocortical axis and its role in reducing levels of these cortisol and dehydroepiandrosterone sulfate.

He points out that part of the reason for the misuse of the term adrenal fatigue arises from the fact that burnout is often only associated with work stress.

“Recently, the ICD-11 [International Classification of Diseases-11] recognized burnout as a disease but focused only on work stress as a cause. The truth is that people can be burned out for many other reasons,” said Dr. Campos.

The Endocrine Society notes on their webpage dedicated to the topic that “adrenal fatigue” as a term, relates to long-term mental, emotional, or physical stress.

“The problem is not the adrenals — it is the exposure to stress in the brain. The brain — only one organ — is responsible for 40% of energy consumption in the body. As you can imagine, if you are under constant stress, you run out of gas very quickly and cannot function well,” he explained.

Adrenal fatigue theory suggests that, under stress, the adrenal glands produce too many short bursts of cortisol resulting in overall reduced cortisol levels and a feeling of being drained.

“As with many other psychiatric diseases, we do not have a way to measure biomarkers in the brain. The testing for cortisol does not work because it fluctuates too much from time to time. So, it is not reliable or reproducible,” Dr. Campos said. 

This leads to the ongoing question of the best way to test and diagnose adrenal fatigue, whether it should be via blood, urine and/or saliva. And even if that is determined, there are still questions about the best time to test, how often, what the normal ranges are and how reliable the tests are.

While adrenal fatigue is not a recognized condition, adrenal insufficiency is medically recognized, resulting from an inability of the adrenal glands to make the life-essential hormones aldosterone and/or cortisol, with symptoms that include fatigue, belly pain, nausea, vomiting, diarrhea, and joint aches.

“Adrenal cocktails are not an effective treatment for adrenal insufficiency because they do not replace the missing hormones,” Dr. Nieman stated, pointing out that anyone with symptoms of adrenal insufficiency needs to see an endocrinologist.

Pratibha Rao, MD, MPH, an endocrinologist at the Cleveland Clinic, Ohio, and medical director of the Adrenal Center at Cleveland Clinic, agreed, advising that if people continue to feel exhausted beyond their normal exertion, then they should get checked for signs of adrenal insufficiency.

“In primary adrenal insufficiency, you can actually start seeing darkening of the gums and of the skin on the palms of the hands or the soles of your feet. Sometimes people can feel dizzy or experience some loss of consciousness,” she said. “If it’s sudden and severe, you may crave salt or have extreme heat or cold intolerance.”

Recognizing and Managing Patient Frustration

The lack of formal diagnostic criteria and medical evidence, however, doesn’t mean that such symptoms as fatigue and depression don’t present, often causing significant distress for patients. While the symptoms might not be associated with the adrenal glands, they still need addressing — but how that is done is, in essence, a bone of contention.

Dr. Rao empathizes with the situation that many people, often young women, find themselves in.

“Patients are frustrated. They’ve gone to multiple doctors across the country, and they feel convinced they have adrenal fatigue, but no medical doctor has endorsed it. They end up coming to us with a cry that has so often gone unanswered.”

This issue also highlights that there are millions of people experiencing mental, emotional, and physical distress of unknown cause who seek help, many of whom believe it is related to their adrenal gland function.

But rather than turning to a social media cure, Dr. Rao stresses that people would benefit more from paying greater attention to following a healthy lifestyle than regularly consuming sugar-rich drinks claimed to offer a solution. Adrenal cocktails are energy-rich, frothy blends of orange juice, coconut milk, cream of tartar, and Himalayan salt.

“We truly are what we eat, and we are what we think,” she noted.

The body is a miraculous machine, but “we forget that it does need maintenance,” Dr. Rao said. “Up to age 30, the body is so forgiving with drugs, alcohol, or whatever insult we do to it, but after the third decade, slowly every cell starts to degenerate instead of growing. We start to see the ill or beneficial effects of lifestyle habits.” 

“We insult the body, and then we say, ‘oh, I have fatigue’ and seek a quick fix,” she added. “Everyone wants instant gratification.”

Dr. Rao cautioned that adrenal cocktails could be dangerous for someone who has other medical conditions.

“If someone has kidney disease, uncontrolled hypertension, or diabetes, for example, then adrenal cocktails are definitely not safe,” Dr. Rao said. “Loading up with potassium and sodium, which is found in high quantities in adrenal cocktails, will actually worsen any kidney damage, while consuming so much sugar will cause an unregulated rise in blood sugar and further damage in someone with diabetes.”

Dr. Rao also stressed that nonprofessional advice given on social media could take patient people down the wrong path with associated danger.

My first civilian job after finishing my training was as an associate and eventually a partner of a pediatrician whose office was in a wing of his large 19th-century home. The pediatrician in the neighboring town had his office in a small house next to his home. This model of small one- or two -provider offices in or nearby their homes was replicated up and down the coast. After 7 years, the 12-minute drive from my home to the office became intolerable and I asked to dissolve what was otherwise a successful partnership. I opened a one-provider office with a 6-minute bike ride commute and my wife served as the billing clerk and bookkeeper.

Those next 10 years of solo practice were the most rewarding, both economically and professionally. Eventually faced with the need to add another provider, I reluctantly joined a recently formed group of primary care physicians who, like me, had been running one- or two-provider offices often with spouses as support staff — basically Mom and Pop operations. However, the group was gradually absorbed by increasingly larger entities and our practices that once were as individual as our personalities became homogenized. Neither my patients nor I liked the new feel of the office.

Still pining for that small office vibe, I continue to wonder if it could be scaled up and adapted to today’s healthcare realities. I recently read a New York Times article describing how a pediatrician has launched such a practice model into the uncharted waters of Greater New York City.

At age 34, Dr. Michel Cohen, a Moroccan-French émigré, opened his storefront pediatric practice in 1994. The upper story housed his loft apartment. A self-described “hippie doctor,” Dr. Cohen developed a following based on his book on parenting and publicity surrounding his role in the even more popular book on French-style parenting titled Bringing up Bebe by Pamela Druckerman. By 2009 his practice had grown to three small storefront offices. However, they weren’t sufficiently profitable. He decided to shun the distractions of his celebrity practice trappings and instead focus on growth, hoping that the gravitas associated with even more office locations would allow him to offer better service and improve the bottom line. Sort of an “economy of scale” notion applied to the small office setting.

He now has 48 offices having added 12 new sites last year with 5 more planned for next year. These are all one- or two-physician installations with two exam rooms per provider. The offices are bright and colorful, focused on appealing to a child’s taste. The furniture is blond wood, most of it based on Dr. Cohen’s designs and in some cases handmade. Current staffing is 112 physicians and nurse practitioners and volume exceeds 100,000 visits per year.

The volume has allowed the practice to add a user-friendly patient portal and offer an after-hours call-in option. The larger volume means that staffing can be more easily adjusted to illness and vacations. The goal is to have the practitioners become identified with their sites and the patients assigned to them whenever possible. Uniformity in office designs allow a provider filling in from another site to easily find supplies and function within a familiar system.

While the sites have generally served upscale gentrified neighborhoods, the practice has recently expanded to less affluent areas and accepts Medicaid. Dr. Cohen’s dream is to expand his network nationally as a nonprofit in which low-income sites would be subsidized by the more profitable offices. A previous attempt at expansion with two offices in Southern California did not work out because the time zone difference didn’t mesh well with the Internet portal.

Wanting to hear a firsthand account from a family on how the Tribeca Pediatric system works, I contacted a neighbor who has recently moved his young family here to Brunswick. His impression was generally positive. He gave high marks to the patient portal for the ability to get school and camp forms and vaccination records quickly. Appointments made electronically was a plus, although the after-hours response time sometimes took an hour or two. He would have preferred to see their assigned provider for a higher percentage of visits, but this seems to be a common complaint even in systems with the greatest availability. Care was dispensed efficiently but didn’t seem to be overly rushed.

In the NY Times article there is one complaint by a former provider who felt she was getting burned out by the system and leaned on 10 minutes for sick visits and 20 minutes for well visits. Personally, I don’t see this as a problem. The length of a visit and the quality of the care are not always related. Given good support services and an efficiently run office, those slot guidelines seem very reasonable, realizing that a skilled clinician must have already learned to adjust his or her pace to the realities of the patient mix. However, as the pediatric sick population has leaned more toward behavioral and mental health problems, a primary care practice should be offering some option for these patients either in-house or with reliable referral relationships. Although the NY Times article doesn’t provide any numbers, it does mention that the providers are generally young and there is some turnover, possibly as providers use the practice as a “stepping stone.”

To some extent Dr. Cohen’s success seems to be the result of his real estate acumen and business sense. Because the majority of recent medical school graduates enter the work force with a substantial debt, it is difficult to imagine that a young physician would have Dr. Cohen’s entrepreneurial passion. However, clearly his success, at least in the short term, demonstrates that there is a substantial percentage of both patients and providers who prefer small personalized offices if given the option. It will be interesting to see if and how Tribeca Pediatrics expands and whether any of the larger existing networks attempt to imitate it.

Dr. Wilkoff practiced primary care pediatrics in Brunswick, Maine, for nearly 40 years. He has authored several books on behavioral pediatrics, including “How to Say No to Your Toddler.” Other than a Littman stethoscope he accepted as a first-year medical student in 1966, Dr. Wilkoff reports having nothing to disclose. Email him at [email protected].

My first civilian job after finishing my training was as an associate and eventually a partner of a pediatrician whose office was in a wing of his large 19th-century home. The pediatrician in the neighboring town had his office in a small house next to his home. This model of small one- or two -provider offices in or nearby their homes was replicated up and down the coast. After 7 years, the 12-minute drive from my home to the office became intolerable and I asked to dissolve what was otherwise a successful partnership. I opened a one-provider office with a 6-minute bike ride commute and my wife served as the billing clerk and bookkeeper.

Those next 10 years of solo practice were the most rewarding, both economically and professionally. Eventually faced with the need to add another provider, I reluctantly joined a recently formed group of primary care physicians who, like me, had been running one- or two-provider offices often with spouses as support staff — basically Mom and Pop operations. However, the group was gradually absorbed by increasingly larger entities and our practices that once were as individual as our personalities became homogenized. Neither my patients nor I liked the new feel of the office.

Still pining for that small office vibe, I continue to wonder if it could be scaled up and adapted to today’s healthcare realities. I recently read a New York Times article describing how a pediatrician has launched such a practice model into the uncharted waters of Greater New York City.

At age 34, Dr. Michel Cohen, a Moroccan-French émigré, opened his storefront pediatric practice in 1994. The upper story housed his loft apartment. A self-described “hippie doctor,” Dr. Cohen developed a following based on his book on parenting and publicity surrounding his role in the even more popular book on French-style parenting titled Bringing up Bebe by Pamela Druckerman. By 2009 his practice had grown to three small storefront offices. However, they weren’t sufficiently profitable. He decided to shun the distractions of his celebrity practice trappings and instead focus on growth, hoping that the gravitas associated with even more office locations would allow him to offer better service and improve the bottom line. Sort of an “economy of scale” notion applied to the small office setting.

He now has 48 offices having added 12 new sites last year with 5 more planned for next year. These are all one- or two-physician installations with two exam rooms per provider. The offices are bright and colorful, focused on appealing to a child’s taste. The furniture is blond wood, most of it based on Dr. Cohen’s designs and in some cases handmade. Current staffing is 112 physicians and nurse practitioners and volume exceeds 100,000 visits per year.

The volume has allowed the practice to add a user-friendly patient portal and offer an after-hours call-in option. The larger volume means that staffing can be more easily adjusted to illness and vacations. The goal is to have the practitioners become identified with their sites and the patients assigned to them whenever possible. Uniformity in office designs allow a provider filling in from another site to easily find supplies and function within a familiar system.

While the sites have generally served upscale gentrified neighborhoods, the practice has recently expanded to less affluent areas and accepts Medicaid. Dr. Cohen’s dream is to expand his network nationally as a nonprofit in which low-income sites would be subsidized by the more profitable offices. A previous attempt at expansion with two offices in Southern California did not work out because the time zone difference didn’t mesh well with the Internet portal.

Wanting to hear a firsthand account from a family on how the Tribeca Pediatric system works, I contacted a neighbor who has recently moved his young family here to Brunswick. His impression was generally positive. He gave high marks to the patient portal for the ability to get school and camp forms and vaccination records quickly. Appointments made electronically was a plus, although the after-hours response time sometimes took an hour or two. He would have preferred to see their assigned provider for a higher percentage of visits, but this seems to be a common complaint even in systems with the greatest availability.

Jason Black, MD, trained in family medicine, worked for Kaiser Permanente, and subsequently completed a fellowship in geriatrics. Today, he treats frail elderly patients, mostly residents of nursing homes and assisted living facilities or living in their own homes, for Gilchrist, a hospice and palliative care organization serving Baltimore and central Maryland.

“I’m practicing family medicine to the extent that I’m treating the family unit, including the anxieties of the adult children, and finding solutions for the parents,” said Dr. Black, one of Gilchrist’s 62 employed providers, one third of whom are physicians. One of his most important roles is medication reconciliation and deprescribing.

Palliative care, a medical specialty that focuses on clarifying the treatment goals of seriously ill patients, helping with end-of-life planning, and emphasizing pain and symptom management, has been growing in recent years. Already well-established in most US hospitals, it is expanding in community settings, often as an extension of hospice programs.

Now, by adding primary care physicians and practices to their service mix, palliative care groups are better meeting the needs of a neglected — and costly — population of frail elders. In doing so, they also are better able to find a niche in the rapidly evolving alphabet soup of value-based care and its varieties of shared savings for providers who post positive outcomes.

Most patients Dr. Black sees find it difficult to visit their doctors in a clinic setting, although they face a variety of medical needs and chronic conditions of aging. They may have a prognosis of several years to live and, thus, do not qualify for hospice care. To him, a palliative approach offers the satisfaction of focusing on what is most important to patients at this difficult time in their lives, rather than predetermined clinical metrics like blood pressure or blood glucose. “It takes a lot of work, but it feels important and rewarding,” he said.

A recent survey of community-dwelling older adults in Ontario, Canada, found most patients fail to receive this treatment homes in the final 3 months of life.
 

Continuums of Patients and Models

Gilchrist started as a nonprofit, hospital-affiliated hospice program in 1994 and in 2000 took on the management of a geriatric medicine practice for its parent, Greater Baltimore Medical Center. Today, its physicians and nurse practitioners see a range of patients in geriatric primary care, palliative medicine, and hospice, according to its chief medical officer, Mark J. Gloth, DO.

“As people progress in their disease, their location — where they call home — may change as well,” Dr. Gloth said. “We offer a continuum of care in order to not lose people through those transitions. That’s the core of our mission — making sure we are there to escort people through the difficult moments in their lives.”

Models for value-based care encompass accountable care organizations (ACOs), including the ACO REACH (Realizing Equity, Access, and Community Health) high-needs model for traditional Medicare patients, and Medicare Shared Savings Programs for fee-for-service beneficiaries. These value-based models offer a variety of opportunities for the palliative care organization to share in savings resulting from keeping the patient out of the hospital or emergency room and other quality and cost benchmarks.
 

Coming Together to Meet Needs

Gilchrist is one of nine hospice and palliative organizations that have joined to form their own multistate ACO, Responsive Care Solutions, focused on the clinical needs of frail elderly Medicare beneficiaries. Hospice of the Valley in Phoenix has Geriatric Solutions, a frail elder physician practice. And Capital Caring Health, a hospice and palliative care agency serving metro Washington, DC, has deployed several physicians and nurse practitioners on the road doing primary care at home, said Heidi Young, MD, its Primary Care at Home Lead Physician.

“Five years ago, we started our primary care practice under the umbrella of a 40-year-old hospice organization because we thought we needed to prepare for the changes that are coming to the hospice model,” Dr. Young said. “The thought was that we’re not just a hospice organization; we’re an advanced illness organization. We will come to your home, whatever that is, and provide your primary care.”

The greatest potential gains for a hospice organization are from assuming 100% risk for a large population of patients, keeping them out of the hospital to lower the costs of their care, then reaping those gains under a value-based profit-sharing model, Dr. Young said.

“Our program is still new and working toward getting more patients aligned into value-based models,” she said. “It’s a work in progress.”
 

A Foot in Each World

Agencies like Capital Caring and Gilchrist derive the largest share of their physician income from billing Medicare Part B and other insurers per visit. But that billing is not enough to break even on physician services.

With hopes for a value-based future, Gilchrist also gets grants from elder-facing charitable foundations to cover up to 40% of the costs of its home-based primary care, according to its president, Catherine Hamel. Hospice care continues to be paid on a per-diem basis by Medicare for eligible terminally ill patients, including Medicare Advantage patients, although the Centers for Medicare & Medicaid Services is reportedly considering new models for the hospice benefit.

The National Partnership for Healthcare and Hospice Innovation (NPHI) is a trade group representing more than 100 nonprofit, hospice-based organizations participating in palliative care and value-based care.

For a hospice to be successful in the evolving post–acute care/end-of-life care landscape, it can no longer rely solely on its hospice line of business, no matter how high-quality, said Ethan McChesney, policy director for the Washington, DC-based nonprofit.

NPHI members have developed their own palliative care programs, and perhaps, a quarter have primary care at home practices, Mr. McChesney said. Some of them acquired existing primary care practices in their service area with which they already had relationships; others created their own.

For hospice organizations building a continuum of services for the seriously ill, adding a primary care at home practice is a natural fit, he said. “You can provide all the services you would as a traditional primary care practice while you have the opportunity to establish long-term relationships with patients and their caregivers that lend themselves to palliative care referrals and then hospice referrals downstream [when the patient becomes eligible for hospice care].” Often, this primary medical care is a mix of in-person and telehealth.

Cameron Muir, MD, NPHI’s chief innovation officer, noted that the hamster wheel for primary care doctors has been spinning faster and faster, with reimbursement going down and costs going up.

But with home-based primary care for frail elders under value-based models, Dr. Muir said, the clinician is paid not for making more visits but for taking great care of the patient: “And I’m actually saving Medicare money and getting credit for the hospitalizations that were avoided.”

To the Editor:

We read with interest the September 2023 Cutis article by Swink et al,¹ “Cat Scratch Disease Presenting With Concurrent Pityriasis Rosea in a 10-Year-Old Girl.” The authors documented the possibility of Bartonella henselae infection as another causative agent for pityriasis rosea (PR) even though the association of PR with human herpesvirus (HHV) 6 and HHV-7 infection is based on several consistent observations and not on occasional findings. The association of PR with endogenous systemic reactivation of HHV-6 and HHV-7 has been identified with different investigations and laboratory techniques. Using polymerase chain reaction, real-time calibrated quantitative polymerase chain reaction, in situ hybridization, immunohistochemistry, and electron microscopy, HHV-6 and HHV-7 have been detected in plasma (a marker of active viral replication), peripheral blood mononuclear cells, and skin lesions from patients with PR.² In addition, HHV-6 and HHV-7 messenger RNA expression and their specific antigens have been detected in PR skin lesions and herpesvirus virions in various stages of morphogenesis as well as in the supernatant of co-cultured peripheral blood mononuclear cells of patients with PR.^2,3 Lastly, the increased levels of several particular cytokines and chemokinesin the sera of patients with PR support a viral role in its pathogenesis.⁴

Bartonella henselae is a gram-negative intracellular facultative bacterium that is commonly implicated in causing zoonotic infections worldwide. The incidence of cat-scratch disease (CSD) was reported to be 6.4 cases per 100,000 population in adults and 9.4 cases per 100,000 population in children aged 5 to 9 years globally.⁵ Approximately 24,000 cases of CSD are reported in the United States every year.⁶ Therefore, considering these data, if B henselae was a causative agent for PR, the eruption would be observed frequently in many patients with CSD, which is not the case. On the contrary, it is possible that B henselae infection may have reactivated HHV-6 and/or HHV-7 infection. It is well established that B henselae causes a robust cell-mediated immune response by activating natural killer and helper T cells (T_H1) and enhancement of cytotoxic T lymphocytes.⁷ It could be assumed that by strongly stimulating the immune response and polarizing it to a specific antigen cell response, B henselae infection may temporarily distract the T cell-mediated control of the latent infections, such as HHV-6 and HHV-7, which may reactivate and cause PR.

It is important to point out that a case of concomitant B henselae and Epstein-Barr virus infection has been described.⁸ Even in that case, the B henselae infection may have reactivated Epstein-Barr virus as well as HHV-6 and HHV-7 in the case described by Swink et al.¹ Epstein-Barr virus reactivation has been detected in one case⁸ through serologic testing—IgM, IgG, Epstein-Barr virus nuclear antigen IgG, and heterophile antibodies—as there were no dermatologic manifestations that may be related to Epstein-Barr virus reactivation from latency.⁹

In conclusion, a viral or bacterial infection such as Epstein-Barr virus or B henselae may have a transactivating function allowing another (latent) virus such as HHV-6 or HHV-7 to reactivate. Indeed, it has been described that SARS-CoV-2 may act as a transactivator agent triggering HHV-6/HHV-7 reactivation, thereby indirectly causing PR clinical manifestation.¹⁰

We read with interest the September 2023 Cutis article by Swink et al,¹ “Cat Scratch Disease Presenting With Concurrent Pityriasis Rosea in a 10-Year-Old Girl.” The authors documented the possibility of Bartonella henselae infection as another causative agent for pityriasis rosea (PR) even though the association of PR with human herpesvirus (HHV) 6 and HHV-7 infection is based on several consistent observations and not on occasional findings. The association of PR with endogenous systemic reactivation of HHV-6 and HHV-7 has been identified with different investigations and laboratory techniques. Using polymerase chain reaction, real-time calibrated quantitative polymerase chain reaction, in situ hybridization, immunohistochemistry, and electron microscopy, HHV-6 and HHV-7 have been detected in plasma (a marker of active viral replication), peripheral blood mononuclear cells, and skin lesions from patients with PR.² In addition, HHV-6 and HHV-7 messenger RNA expression and their specific antigens have been detected in PR skin lesions and herpesvirus virions in various stages of morphogenesis as well as in the supernatant of co-cultured peripheral blood mononuclear cells of patients with PR.^2,3 Lastly, the increased levels of several particular cytokines and chemokinesin the sera of patients with PR support a viral role in its pathogenesis.⁴

Cellulitis is the most common reason for skin-related hospital admissions.¹ Despite its frequency, it is suspected that many cases of cellulitis are misdiagnosed as other etiologies presenting with similar symptoms such as a ruptured Baker cyst. These cysts are located behind the knee and can present with calf pain, peripheral edema, and erythema when ruptured. Symptoms of a ruptured Baker cyst can be indistinguishable from cellulitis as well as deep vein thrombosis (DVT), both manifesting with lower extremity pain, swelling, and erythema, making diagnosis challenging.² The hemorrhagic crescent sign—a crescent of ecchymosis distal to the medial malleolus and on the foot that results from synovial injury or rupture—can be a useful diagnostic tool to differentiate between the causes of acute swelling and pain of the leg.² When observed, the hemorrhagic crescent sign supports testing for synovial pathology at the knee.

A 63-year-old man presented to an outside hospital for evaluation of a fever (temperature, 101 °F [38.3 °C]), as well as pain, edema, and erythema of the right lower leg of 2 days’ duration. He had a history of leg cellulitis, gout, diabetes mellitus, lymphedema, and peripheral neuropathy. On admission, he was found to have elevated C-reactive protein (45 mg/L [reference range, <8 mg/L]) and mild leukocytosis (13,500 cells/μL [reference range, 4500–11,000 cells/μL]). A venous duplex scan did not demonstrate signs of thrombosis. Antibiotic therapy was started for suspected cellulitis including levofloxacin, piperacillin-tazobactam, and linezolid. Despite broad-spectrum antibiotic coverage, the patient continued to be febrile and experienced progressive erythema and swelling of the right lower leg, at which point he was transferred to our institution. A new antibiotic regimen of vancomycin, cefepime, and clindamycin was started and showed no improvement, after which dermatology was consulted.

Physical examination revealed unilateral edema and calor of the right lower leg with a demarcated erythematous rash extending to the level of the knee. Furthermore, a hemorrhagic crescent sign was present below the right medial malleolus (Figure). The popliteal fossa was supple, though the patient was adamant that he had a Baker cyst. Punch biopsies demonstrated epidermal spongiosis and extensive edema with perivascular inflammation. No organisms were found by stain and culture. Ultrasound records confirmed a Baker cyst present at least 4 months prior; however, a repeat ultrasound showed resolution. A diagnosis of pseudocellulitis secondary to Baker cyst rupture was made, and corticosteroids were started, resulting in marked reduction in erythema and edema of the lower leg and hospital discharge.

This case highlights the importance of early involvement of dermatology when cellulitis is suspected. A study of 635 patients in the United Kingdom referred to dermatology for lower limb cellulitis found that 210 (33%) patients did not have cellulitis and only 18 (3%) required hospital admission.³ Dermatology consultations have been shown to benefit patients with inflammatory skin disease by decreasing length of stay and reducing readmissions.⁴

Our patient had several risk factors for cellulitis, including obesity, lymphedema, and chronic kidney disease, in addition to having fevers and unilateral involvement. However, failure of symptoms to improve with broad-spectrum antibiotics made a diagnosis of cellulitis less likely. In this case, a severe immune response to the ruptured Baker cyst mimicked the presentation of cellulitis.

Ruptured Baker cysts have been reported to cause acute leg swelling, mimicking the symptoms of cellulitis or DVT.^2,5 The presence of a hemorrhagic crescent sign can be a useful diagnostic tool, as in our patient, because it has been reported as an indication of synovial injury or rupture, supporting the exclusion of cellulitis or DVT when it is observed.⁶ Prior reports have observed ecchymosis on the foot in as little as 1 day after the onset of calf swelling and at the lateral malleolus 3 days after the onset of calf swelling.⁵

Following suspicion of a ruptured Baker cyst causing pseudocellulitis, an ultrasound can be used to confirm the diagnosis. Ultrasonography shows a large hypoechoic space behind the calf muscles, which is pathognomonic of a ruptured Baker cyst.⁷

In conclusion, when a hemorrhagic crescent sign is observed, one should be suspicious for a ruptured Baker cyst or other synovial pathology as an etiology of pseudocellulitis. Early recognition of the hemorrhagic crescent sign can help rule out cellulitis and DVT, thereby reducing the amount of intravenous antibiotic prescribed, decreasing the length of hospital stay, and reducing readmission.
