Hepatocellular carcinoma risk declines after direct-acting antiviral treatment but remains high enough to justify screening for at least 7 years after hepatitis C cure, according to a new report.

Among patients with cirrhosis and fibrosis-4 (FIB-4) scores of 3.25 or higher, the incidence of hepatocellular carcinoma appeared to decline progressively each year up to 7 years after a sustained virologic response, although the rate remained above the 1% per year threshold that warrants screening.

“The majority of patients with hepatitis C have been treated and cured in the United States,” George Ioannou, MD, the senior study author and professor of medicine at the University of Washington, Seattle, said in an interview. “After hepatitis C eradication, these patients generally do very well from the liver standpoint, but the one thing they have to continue worrying about is development of liver cancer.”

Dr. Ioannou, who is also director of hepatology at the Veterans Affairs Puget Sound Health Care System, Seattle, noted that patients may be screened “indefinitely,” which places a burden on the patients and the health care system.

“We are still not sure to what extent the risk of liver cancer declines after hepatitis C eradication as more and more time accrues,” he said. “In those who had cirrhosis of the liver prior to hepatitis C cure, we are still not certain if there is a time point after hepatitis C cure when we can tell a patient that their risk of liver cancer is now very low and we no longer need to keep screening for liver cancer.”

The study was published online in Gastroenterology.
 

Risk calculations

In a previous study, Dr. Ioannou and colleagues found that hepatocellular carcinoma risk declined during the first 4 years of follow-up after a sustained virologic response from direct-acting antiviral medications. But the follow-up time wasn’t long enough to determine whether the cancer risk continues to decline to levels low enough to forgo screening.

In this study, Dr. Ioannou and colleagues extended the follow-up to 7 years. They were curious to see whether the cancer risk declines enough to drop the screening requirement, particularly as related to pretreatment cirrhosis and fibrosis-4 scores.

The research team analyzed electronic health records from the Veterans Affairs Corporate Data Warehouse, a national repository of Veterans Health Administration records developed specifically for research purposes.

The researchers included 29,033 patients in the Veterans Affairs health care system who had been infected with hepatitis C virus and were treated with direct-acting antivirals between January 2013 and December 2015. The patients had a sustained virologic response, which is defined as a viral load below the lower limit of detection at least 12 weeks after therapy completion.

The patients were followed for incident hepatocellular carcinoma until December 2021. The researchers then calculated the annual incidence during each year of follow-up after treatment.

About 96.6% of patients were men, and 52.2% were non-Hispanic White persons. The average age was 61 years. The most common conditions were alcohol use disorder (43.7%), substance use disorder (37.7%), and diabetes (28.9%).

Among the 7,533 patients with pretreatment cirrhosis, 948 (12.6%) developed hepatocellular carcinoma during a mean follow-up period of 4.9 years. Among patients with FIB-4 scores of 3.25 or higher, the annual incidence decreased from 3.8% in the first year to 1.4% in the seventh year but remained substantial up to 7 years after sustained virologic response. Among patients with both cirrhosis and a high FIB-4 score, the annual rate ranged from 0.7% to 1.3% and didn’t change significantly over time.

Among the 21,500 patients without pretreatment cirrhosis, 541 (or 2.5%) developed hepatocellular carcinoma during a mean follow-up period of 5.4 years. The incidence rate was significantly higher for patients with high FIB-4 scores. Among patients without cirrhosis but who had a high FIB-4 score, the annual rate remained stable but substantial (from 0.8% to 1.3%) for up to 7 years.

In a subgroup analysis that examined incidence according to changes in FIB-4 scores before and after treatment, the rate remained high among those with cirrhosis regardless of a score change. Among those without cirrhosis but who had a persistently high FIB-4 score, the incidence was high. In those without cirrhosis whose FIB-4 score dropped, the incidence was lower.

“The study demonstrates a clear decline in the risk of liver cancer over time after hepatitis C cure in the highest-risk group. This is very positive news for patients,” Dr. Ioannou said. “However, even with that decline in risk up to 7 years after eradication of hepatitis C with direct-acting antivirals, the risk is still high enough to warrant liver cancer screening.”
 

Future concerns

For a follow-up study, Dr. Ioannou and colleagues plan to adjust their analyses for other factors that influence the risk of liver cancer, such as age and nonalcoholic fatty liver disease. Other studies could increase the follow-up time beyond 7 years and assess how changes in diabetes, weight management, and alcohol use might affect liver cancer risk.

“With the availability of safe and effective direct-acting antiviral treatments, a growing number of patients have been or will be treated and cured of their hepatitis C infection,” Nicole Kim, MD, one of the lead authors and a transplant hepatology fellow at the University of Washington, Seattle, told this news organization.

“It is therefore important for us to develop a better understanding of how liver cancer risk might change after treatment, so we can improve the care we provide to this patient population,” she said.

The results require validation in nonveteran cohorts, the study authors write, as well as follow-up after the COVID-19 pandemic, when screening and diagnostic practices were restricted.

“Several studies have demonstrated that HCC [hepatocellular carcinoma] surveillance is underused in clinical practice, including in patients after [sustained virologic response],” Amit Singal, MD, clinical chief of hepatology and medical director of the liver tumor program at the University of Texas Southwestern Medical Center, told this news organization.

Dr. Singal, who wasn’t involved with this study, is evaluating several intervention strategies to increase surveillance utilization. His research group is conducting a multicenter randomized trial using mailed outreach invitations and is also evaluating a biomarker, PLSec-AFP, to identify patients with the highest risks who may warrant more intensive surveillance strategies.

“We have recently validated the performance of this biomarker in a large cohort of patients with cirrhosis, including some with cured hepatitis C virus infection,” he said.

The study was funded by an NIH/NCI grant and a VA CSR under Dr. Ioannou. The manuscript writing was supported by the NIH under Dr. Kim and co-author Philip Vutien. Dr. Singal has disclosed no relevant financial relationships.

As pediatricians, almost all of our clinic visits include some anticipatory guidance and recommendations on ways to promote well-being and prevent illness and injury for our patients. Because of minority stress, discrimination, and increased exposure to adverse childhood experiences, LGBTQ+ patients are disproportionately affected by certain health conditions including depression, anxiety, substance use, homelessness, as well as HIV and other sexually transmitted infections (STIs).¹ While LGBTQ+ youth could benefit from additional guidance, counseling, and interventions related to these health disparities and have expressed interest in talking about these topics with their providers, sexual and gender minority youth also stress that they want to be treated as any other youth.² Extending counseling for preventive care measures such as preexposure prophylaxis (PrEP) for HIV to all sexually active youth could help to destigmatize LGBTQ+ youth as being “different” from other youth and also help to increase overall access to HIV prevention services.³

Described by some as the “birth control” for HIV infection, PrEP is taken on an ongoing basis by those who are HIV negative before potential exposures to HIV in order to prevent new HIV infections. PrEP was first approved as a daily pill for adults in 2015 by the Food and Drug Administration with extension in 2018 to all individuals at risk for HIV weighing at least 35 kg after safety and efficacy data showed it could be used routinely for adolescents.⁴ When taken daily, oral PrEP can decrease the risk of HIV from sexual contact by more than 90% and from injection drug use by around 70%. As PrEP is highly effective with low risk for side effects, the U.S. Preventive Services Task Force (USPSTF) gave PrEP a “Grade A” recommendation for use in those at high risk for HIV infection in 2019.⁵ Since efficacy is closely tied to adherence, the first injectable PrEP (given at 0, 1, and 2 months with dosing then every 2 months) was also recently FDA approved in late 2021.⁶

Since HIV infection disproportionately affects LBGTQ+ individuals, and particularly LBGTQ+ youth of color, counseling related to PrEP has been largely targeted to these groups.⁷ Insurance and financial barriers to PrEP have been greatly reduced over the past several years through changes in insurance coverage (strengthened by the USPSTF recommendation), supplemental insurance programs, and pharmaceutical copay programs. Many states (but not all) also include HIV in the definition of STIs and allow minors to consent to PrEP services without a parent or guardian. Unfortunately, despite the high efficacy of PrEP and efforts to decrease barriers, rates of PrEP use continue to be extremely low, especially in youth, with only 15.6% of those aged 16-24 who are at risk for HIV in the United States actually taking PrEP in 2019.⁸ Many barriers to PrEP continue to exist including lack of awareness of PrEP, stigma surrounding HIV and PrEP, and lack of PrEP providers.

In order to address these low rates of PrEP uptake, the Centers for Disease Control and Prevention now recommends that medical providers discuss PrEP with all sexually active patients.⁶ PrEP should not be seen or discussed as something only relevant to LBGTQ+ populations, but rather as another tool in everyone’s “sexual health toolbox” that can allow us to experience human connection and pleasure through sexual activity while also having more control over what happens to our bodies. Not only will this allow more patients to access PrEP directly, it will also decrease the stigma of talking about HIV and PrEP and strengthen youths’ sense of autonomy and control over their own sexual health.

Since PrEP is a relatively new medical service, many providers will need to learn more about PrEP to at least have initial discussions with patients and to feel comfortable prescribing this themselves (See Resources). Below are also some suggestions to incorporate into your practice in order to advocate for the health and well-being of all your patients, including LGBTQ+ youth.

• Once your patients are 13 years and older, spend time with them alone to confidentially discuss more sensitive topics such as sexual health, mental health, and substance use.
• For all patients who are sexually active or considering sexual activity in the near future, discuss topics to help them control what happens to their bodies including consent, condoms, birth control, PrEP, and routine STI screening.
• Recommend PrEP to anyone who is sexually active and may be at increased risk for HIV infection or who is interested in taking PrEP for HIV prevention.
• Learn more about PrEP and start prescribing it to your own patients or become familiar with providers in your area to whom you could refer patients who are interested. While no certification is needed to prescribe PrEP, programs exist to help providers become more familiar with how to prescribe PrEP.

PrEP was first approved as a daily pill for adults in 2015 by the Food and Drug Administration with extension in 2018 to all individuals at risk for HIV weighing at least 35 kg after safety and efficacy data showed it could be used routinely for adolescents.⁴ When taken daily, oral PrEP can decrease the risk of HIV from sexual contact by more than 90% and from injection drug use by around 70%. As PrEP is highly effective with low risk for side effects, the U.S. Preventive Services Task Force (USPSTF) gave PrEP a “Grade A” recommendation for use in those at high risk for HIV infection in 2019.⁵ Since efficacy is closely tied to adherence, the first injectable PrEP (given at 0, 1, and 2 months with dosing then every 2 months) was also recently FDA approved in late 2021.⁶

Since HIV infection disproportionately affects LBGTQ+ individuals, and particularly LBGTQ+ youth of color, counseling related to PrEP has been largely targeted to these groups.⁷ Insurance and financial barriers to PrEP have been greatly reduced over the past several years through changes in insurance coverage (strengthened by the USPSTF recommendation), supplemental insurance programs, and pharmaceutical copay programs. Many states (but not all) also include HIV in the definition of STIs and allow minors to consent to PrEP services without a parent or guardian. Unfortunately, despite the high efficacy of PrEP and efforts to decrease barriers, rates of PrEP use continue to be extremely low, especially in youth, with only 15.6% of those aged 16-24 who are at risk for HIV in the United States actually taking PrEP in 2019.⁸ Many barriers to PrEP continue to exist including lack of awareness of PrEP, stigma surrounding HIV and PrEP, and lack of PrEP providers.

In order to address these low rates of PrEP uptake, the Centers for Disease Control and Prevention now recommends that medical providers discuss PrEP with all sexually active patients.⁶ PrEP should not be seen or discussed as something only relevant to LBGTQ+ populations, but rather as another tool in everyone’s “sexual health toolbox” that can allow us to experience human connection and pleasure through sexual activity while also having more control over what happens to our bodies. Not only will this allow more patients to access PrEP directly, it will also decrease the stigma of talking about HIV and PrEP and strengthen youths’ sense of autonomy and control over their own sexual health.

Since PrEP is a relatively new medical service, many providers will need to learn more about PrEP to at least have initial discussions with patients and to feel comfortable prescribing this themselves (See Resources). Below are also some suggestions to incorporate into your practice in order to advocate for the health and well-being of all your patients, including LGBTQ+ youth.

• Once your patients are 13 years and older, spend time with them alone to confidentially discuss more sensitive topics such as sexual health, mental health, and substance use.
• For all patients who are sexually active or considering sexual activity in the near future, discuss topics to help them control what happens to their bodies including consent, condoms, birth control, PrEP, and routine STI screening.
• Recommend PrEP to anyone who is sexually active and may be at increased risk for HIV infection or who is interested in taking PrEP for HIV prevention.
• Learn more about PrEP and start prescribing it to your own patients or become familiar with providers in your area to whom you could refer patients who are interested. While no certification is needed to prescribe PrEP, programs exist to help providers become more familiar with how to prescribe PrEP.

While two new studies reiterate a possible relationship between adenovirus 41 and acute hepatitis of unknown cause in children, whether these infections are significant or merely bystanders remains unclear.

In both studies – one conducted in Alabama and the other conducted in the United Kingdom – researchers found that 90% of children with acute hepatitis of unknown cause tested positive for adenovirus 41. The virus subtype is not an uncommon infection, but it usually causes gastroenteritis in children.

“Across the world, adenovirus continues to be a common signal” in these pediatric hepatitis cases, said Helena Gutierrez, MD, the medical director of the Pediatric Liver Transplant Program at the University of Alabama at Birmingham, in an interview. She led one of the studies. More data are necessary to understand what role this virus may play in these cases, she said.

In November, the Alabama Department of Public Health and the U.S. Centers for Disease Control and Prevention began investigating a cluster of severe pediatric hepatitis cases at the Children’s of Alabama hospital in Birmingham. These children also tested positive for adenovirus. In April, the United Kingdom announced they were investigating similar cases, and the CDC expanded their search nationally. As of July 8, 1,010 cases in 35 countries have been reported to the World Health Organization. There are 263 confirmed cases in the United Kingdom and 332 cases under investigation by the CDC in the United States, according to the most recent counts.

The two studies, both published in the New England Journal of Medicine, provide additional clinical data on a number of these mysterious hepatitis cases. Dr. Gutierrez’s study looked at nine children admitted for hepatitis of unknown origin between October 1 and February 28. Patients had a median age of 2 years 11 months and two required liver transplants, and there were no deaths.

Eight out of nine patients (89%) tested positive for adenovirus, and all five of the samples that were of sufficient quality for gene sequencing tested positive for adenovirus 41. None of the six liver biopsies performed found signs of adenovirus infection, but the liver tissue samples of three patients tested positive for adenovirus via PCR.

The second study involved 44 children referred to a liver transplantation center in the United Kingdom between January 1 and April 11, 2022. The median age for patients was 4 years. Six children required liver transplants, and there were no deaths. Of the 30 patients who underwent molecular adenovirus testing, 27 (90%) were positive for adenovirus 41. Liver samples of nine children (3 from biopsies and 6 from explanted livers) all tested negative for adenovirus antibodies.

In both studies, however, the median adenovirus viral load of patients needing a transplant was much higher than the viral loads in children who did not require liver transplants.

Although most of the clinical features and test results of these cases suggest that adenovirus may be involved, the negative results in histology are “intriguing,” Chayarani Kelgeri, MD, a consultant pediatric hepatologist at the Birmingham Women’s and Children’s Hospital, U.K., said in an email. She is the lead author of the U.K. study. “Whether this is because the liver injury we see is an aftermath of the viral infection, the mechanism of injury is immune mediated, and if other cofactors are involved is being explored,” she added. “Further investigations being undertaken by UK Health Security Agency will add to our understanding of this illness.”

Although there is a high adenovirus positivity rate amongst these cases, there is not enough evidence yet to say adenovirus 41 is a new cause of pediatric hepatitis in previously healthy children, said Saul Karpen, MD, PhD, the division chief of pediatric gastroenterology, hepatology, and nutrition at Emory University School of Medicine, Atlanta. He wrote an editorial accompanying the two NEJM studies.

The CDC has not yet found an increase in pediatric hepatitis cases, according to a recent analysis, though the United Kingdom has found an uptick in cases this year, he told this news organization. Also, the cases highlighted in both articles showed no histological evidence of adenovirus in liver biopsies. “That’s completely opposite of what we generally see in adenoviral hepatitis that can be quite severe,” he said, adding that in general, there are detectable viral particles and antigens in affected livers.

“These two important reports indicate to those inside and outside the field of pediatric hepatology that registries and clinical studies of acute hepatitis in children are sorely needed,” Dr. Karpen writes in the editorial; “It is likely that with greater attention to collecting data on cases and biospecimens from children with acute hepatitis, we will be able to determine whether this one virus, human adenovirus 41, is of relevance to this important and serious condition in children.”

Dr. Gutierrez, Dr. Kelgeri, and Dr. Karpen report no relevant financial relationships.

Sitting at his desk in Sea Girt, N.J., John Schwind is eager to demonstrate his ReadiMask 365. He holds up what looks like a white sheet of memo paper, peels off a protective liner, and sticks the mask first to his nose. He glides his fingers down his face, over his cheeks, and to his chin, sealing the mask and then demonstrating how easy it is to talk with it in place.

The mask’s medical adhesive sticks directly to the face, without causing breakouts, he said. It doesn’t let air leak and won’t fog his glasses. It’s strapless, so it won’t hurt his ears or make them stick out.

This fall, Mr. Schwind, the CEO of Global Safety First, is hoping to take home $150,000 as one of the two top winners of the federal Mask Innovation Challenge. He has made it to the top 10 but realizes he still has a ton of competition.

After the challenge launched in late 2021, nearly 1,500 submissions were received, says Kumiko Lippold, PhD, a health scientist and manager of the Mask Innovation Challenge. The challenge is run by Dr. Lippold and others at the Division of Research, Innovation, and Ventures (DRIVe), which is part of the Biomedical Advanced Research and Development Authority (BARDA) at the U.S. Department of Health & Human Services.

Like the rest of us, Dr. Lippold knows that masks desperately need a makeover. The point of the challenge is to inspire and design masks that are comfortable, even with long wear, and that provide excellent protection. The aim is not only to get us through this pandemic but also future pandemics and other public health emergencies. “We are focused on building masks for the next pandemic, the next wildfires,” she says.

The project is a partnership among BARDA’s DRIVe, the National Institute for Occupational Safety and Health (NIOSH), and the National Institute of Standards and Technology (NIST).

While NIOSH is a partner in the challenge, giving feedback to mask developers, “the mask challenge is entirely separate from the NIOSH approval process,” Dr. Lippold says. Companies can then pursue NIOSH approval on their own, later, if they wish. The agency certifies only masks and respirators.
 

Preview of masks to come

“We’ve seen some really amazing things,” Dr. Lippold said of the new designs. She didn’t want to play favorites, so she gave an overview of innovations. Some designs have transparent materials, or partially see-through materials, so facial expressions can be read. “We’ve also seen really unique bio-based materials that are derived from natural products. We’ve seen sensors in some.”

One mask model has origami folds, which increase overall surface and breathing area. Some 3D-printed masks promise a custom fit and take into account whether a person’s nose bridge is low or high.
 

And the finalists are ...

ReadiMask 365: “I can wear this all day long,” Mr. Schwind said of his new design. It has a nano fiber filter and is flexible. Besides the one in the BARDA challenge, the company has other ReadiMasks on the market. “The most important thing is comfort,” he says. “Second is protection. If they don’t feel they have a good seal, users don’t have confidence in the mask.”

He offers various sizes of ReadiMasks, from small sizes designed for women with smaller faces to extra-large, “for NFL linemen.”

ClearMask: “We are the original clear mask,” says Aaron Hsu, CEO and co-founder of ClearMask in Baltimore. The company began in 2017, and the clear design was inspired by a company co-founder who is deaf. She was scheduled to have surgery, and her sign language interpreter did not show up, leaving her to try to communicate in the operating room with masked health care providers. There were no transparent masks available then, Mr. Hsu says.

“Being able to work with BARDA and getting their wisdom is invaluable,” he says.

The makers of ClearMask think masks are here to stay, at least for some. “I think a certain percentage of the population will continue to wear them, regardless,” said Mr. Hsu. He predicts health care settings will become stricter about wearing masks.

“Even now, when you even walk in to a hospital, you might be required to wear a mask,” he says, even as a visitor. His company’s masks are easy to adjust and are secured around the head, so your ears don’t get sore, he says.

4C Air: The BreSafe transparent mask is semi-transparent and is made of a nanomaterial that provides high levels of filtration and breathability with some transparency.

Air99: Based on origami principles, the Airgami mask is meant to improve fit, breathability, and aesthetics over existing masks. “Airgami fits better, works better and looks better,” says Min Xiao, a company spokesperson. “It won’t fall off the nose or collapse onto the mouth, and eyeglasses fog less, she says. Voices are less muffled.” It’s also reusable, rinseable and can be heat disinfected, she says. It went on the market in November 2020.

Air Flo Labs: Flo Mask Pro, like the company’s other designs, conducted over 100 3D facial scans across many ethnicities to produce a better fit, says Kevin Ngo, its creator. For the adult masks, two nose bridge sizes are offered. And users can choose a Pro Filter, with 99% filtration, or an Everyday, which is meant to be much more breathable than other masks. “Our silicone gasket is incredibly soft and gentle on the skin,” Mr. Ngo says. “In addition,we offer indents for glasses, which prevent any fogging.” The company began shipping in May; several thousand masks are in use now, Mr. Ngo said.

Georgetown University: This team’s smart mask is made of metallic foams that can be cleaned and reused.

Levi Strauss: The form of the mask can be made by any basic garment factory. It aims to activate the apparel supply chain as another source of low-cost, high-performance masks.

Matregenix: This mask, made of a transparent nanofiber, allows for easier communication while having high filtration.

SEAL Lab: The SINEW mask stands for Smart, Individualized, Near-Face, Extended Wear. The mask used technology to overcome flaws of traditional respirators, with the same degree of protection. It doesn’t make contact with the skin of the wearer’s face.

StaySafeNow: A team from Harvard University developed Crystal Guard, a reusable, cost-effective clear mask. Its developers say it’s meant to be especially useful for essential workers, teachers, and others who have to communicate to do their work.
 

Bye-bye N95?

“From our perspective, our goal with the mask challenge was not to replace the N95 respirator,” Dr. Lippold says. N95 masks, which NIOSH certifies, are valuable and protect people in high-risk settings. “With the mask challenge, our goal was really to provide the public with a comparable alternative that really meets their specific level of risk.” Working in a health care setting carries a different risk, she says, than going to the grocery store.

“A common complaint with the N95 is that they are very uncomfortable.” It’s a major barrier to compliance, “and we wanted to address that gap. We didn’t directly compare [the entries] to an N95,” she says, although their testing was similar to NIOSH’s. A number of finalists say they will pursue NIOSH approval, she says.

Meanwhile, some of the finalists’ masks are for sale. Air Flo Labs, for instance, has its Flo Mask Pro for sale online, noting that BARDA allowed it to release the test results from NIOSH and NIST.
 

Getting from 1,500 to 10

In the first phase of the challenge, Dr. Lippold says, “the goal was to engage as wide an audience as possible.” With the second phase, the bar was set a bit higher. Instead of just submitting ideas on paper, companies had to submit prototypes for lab testing. “We got about 80 submissions,” she says.

Those 80 were whittled down to 10 finalists. Teams had sent prototypes, and experts, including those from NIOSH and NIST, rated them, sometimes looking at multiple copies of the masks. Experts looked at how well the masks filtered the air, how breathable they were, and other data. Once the feedback was given to the mask companies, they entered a redesign period. “Scientists can take this data and basically make these prototypes better,” Dr. Lippold says.

The final round of testing will be in September, and the winners will be announced in the fall. The opportunity allowed companies to have their products go through testing they might not otherwise have been able to get, she says.

And users can choose a Pro Filter, with 99% filtration, or an Everyday, which is meant to be much more breathable than other masks. “Our silicone gasket is incredibly soft and gentle on the skin,” Mr. Ngo says. “In addition,we offer indents for glasses, which prevent any fogging.” The company began shipping in May; several thousand masks are in use now, Mr. Ngo said.

Georgetown University: This team’s smart mask is made of metallic foams that can be cleaned and reused.

Levi Strauss: The form of the mask can be made by any basic garment factory. It aims to activate the apparel supply chain as another source of low-cost, high-performance masks.

Matregenix: This mask, made of a transparent nanofiber, allows for easier communication while having high filtration.

SEAL Lab: The SINEW mask stands for Smart, Individualized, Near-Face, Extended Wear. The mask used technology to overcome flaws of traditional respirators, with the same degree of protection. It doesn’t make contact with the skin of the wearer’s face.

StaySafeNow: A team from Harvard University developed Crystal Guard, a reusable, cost-effective clear mask. Its developers say it’s meant to be especially useful for essential workers, teachers, and others who have to communicate to do their work.
 

Bye-bye N95?

“From our perspective, our goal with the mask challenge was not to replace the N95 respirator,” Dr. Lippold says. N95 masks, which NIOSH certifies, are valuable and protect people in high-risk settings. “With the mask challenge, our goal was really to provide the public with a comparable alternative that really meets their specific level of risk.” Working in a health care setting carries a different risk, she says, than going to the grocery store.

“A common complaint with the N95 is that they are very uncomfortable.” It’s a major barrier to compliance, “and we wanted to address that gap. We didn’t directly compare [the entries] to an N95,” she says, although their testing was similar to NIOSH’s. A number of finalists say they will pursue NIOSH approval, she says.

Meanwhile, some of the finalists’ masks are for sale. Air Flo Labs, for instance, has its Flo Mask Pro for sale online, noting that BARDA allowed it to release the test results from NIOSH and NIST.
 

Getting from 1,500 to 10

In the first phase of the challenge, Dr. Lippold says, “the goal was to engage as wide an audience as possible.” With the second phase, the bar was set a bit higher. Instead of just submitting ideas on paper, companies had to submit prototypes for lab testing. “We got about 80 submissions,” she says.

Those 80 were whittled down to 10 finalists. Teams had sent prototypes, and experts, including those from NIOSH and NIST, rated them, sometimes looking at multiple copies of the masks. Experts looked at how well the masks filtered the air, how breathable they were, and other data. Once the feedback was given to the mask companies, they entered a redesign period. “Scientists can take this data and basically make these prototypes better,” Dr. Lippold says.

The final round of testing will be in September, and the winners will be announced in the fall. The opportunity allowed companies to have their products go through testing they might not otherwise have been able to get, she says.

Sitting at his desk in Sea Girt, N.J., John Schwind is eager to demonstrate his ReadiMask 365. He holds up what looks like a white sheet of memo paper, peels off a protective liner, and sticks the mask first to his nose. He glides his fingers down his face, over his cheeks, and to his chin, sealing the mask and then demonstrating how easy it is to talk with it in place.

The mask’s medical adhesive sticks directly to the face, without causing breakouts, he said. It doesn’t let air leak and won’t fog his glasses. It’s strapless, so it won’t hurt his ears or make them stick out.

This fall, Mr. Schwind, the CEO of Global Safety First, is hoping to take home $150,000 as one of the two top winners of the federal Mask Innovation Challenge. He has made it to the top 10 but realizes he still has a ton of competition.

After the challenge launched in late 2021, nearly 1,500 submissions were received, says Kumiko Lippold, PhD, a health scientist and manager of the Mask Innovation Challenge. The challenge is run by Dr. Lippold and others at the Division of Research, Innovation, and Ventures (DRIVe), which is part of the Biomedical Advanced Research and Development Authority (BARDA) at the U.S. Department of Health & Human Services.

Like the rest of us, Dr. Lippold knows that masks desperately need a makeover. The point of the challenge is to inspire and design masks that are comfortable, even with long wear, and that provide excellent protection. The aim is not only to get us through this pandemic but also future pandemics and other public health emergencies. “We are focused on building masks for the next pandemic, the next wildfires,” she says.

The project is a partnership among BARDA’s DRIVe, the National Institute for Occupational Safety and Health (NIOSH), and the National Institute of Standards and Technology (NIST).

While NIOSH is a partner in the challenge, giving feedback to mask developers, “the mask challenge is entirely separate from the NIOSH approval process,” Dr. Lippold says. Companies can then pursue NIOSH approval on their own, later, if they wish. The agency certifies only masks and respirators.
 

Preview of masks to come

“We’ve seen some really amazing things,” Dr. Lippold said of the new designs. She didn’t want to play favorites, so she gave an overview of innovations. Some designs have transparent materials, or partially see-through materials, so facial expressions can be read. “We’ve also seen really unique bio-based materials that are derived from natural products. We’ve seen sensors in some.”

One mask model has origami folds, which increase overall surface and breathing area. Some 3D-printed masks promise a custom fit and take into account whether a person’s nose bridge is low or high.
 

And the finalists are ...

ReadiMask 365: “I can wear this all day long,” Mr. Schwind said of his new design. It has a nano fiber filter and is flexible. Besides the one in the BARDA challenge, the company has other ReadiMasks on the market. “The most important thing is comfort,” he says. “Second is protection. If they don’t feel they have a good seal, users don’t have confidence in the mask.”

He offers various sizes of ReadiMasks, from small sizes designed for women with smaller faces to extra-large, “for NFL linemen.”

ClearMask: “We are the original clear mask,” says Aaron Hsu, CEO and co-founder of ClearMask in Baltimore. The company began in 2017, and the clear design was inspired by a company co-founder who is deaf. She was scheduled to have surgery, and her sign language interpreter did not show up, leaving her to try to communicate in the operating room with masked health care providers. There were no transparent masks available then, Mr. Hsu says.

“Being able to work with BARDA and getting their wisdom is invaluable,” he says.

The makers of ClearMask think masks are here to stay, at least for some. “I think a certain percentage of the population will continue to wear them, regardless,” said Mr. Hsu. He predicts health care settings will become stricter about wearing masks.

“Even now, when you even walk in to a hospital, you might be required to wear a mask,” he says, even as a visitor. His company’s masks are easy to adjust and are secured around the head, so your ears don’t get sore, he says.

4C Air: The BreSafe transparent mask is semi-transparent and is made of a nanomaterial that provides high levels of filtration and breathability with some transparency.

Air99: Based on origami principles, the Airgami mask is meant to improve fit, breathability, and aesthetics over existing masks. “Airgami fits better, works better and looks better,” says Min Xiao, a company spokesperson. “It won’t fall off the nose or collapse onto the mouth, and eyeglasses fog less, she says. Voices are less muffled.” It’s also reusable, rinseable and can be heat disinfected, she says. It went on the market in November 2020.

Four years ago, when Dr. Karen Giuliano went to a Boston hospital for hip replacement surgery, she was given a pale-pink bucket of toiletries issued to patients in many hospitals. Inside were tissues, bar soap, deodorant, toothpaste, and, without a doubt, the worst toothbrush she’d ever seen.

“I couldn’t believe it. I got a toothbrush with no bristles,” she said. “It must have not gone through the bristle machine. It was just a stick.”

To most patients, a useless hospital toothbrush would be a mild inconvenience. But to Dr. Giuliano, a nursing professor at the University of Massachusetts, Amherst, it was a reminder of a pervasive “blind spot” in U.S. hospitals: the stunning consequences of unbrushed teeth.

Hospital patients not getting their teeth brushed, or not brushing their teeth themselves, is believed to be a leading cause of hundreds of thousands of cases of pneumonia a year in patients who have not been put on a ventilator. Pneumonia is among the most common infections that occur in health care facilities, and a majority of cases are nonventilator hospital-acquired pneumonia, or NVHAP, which kills up to 30% of those infected, Dr. Giuliano and other experts said.

But unlike many infections that strike within hospitals, the federal government doesn’t require hospitals to report cases of NVHAP. As a result, few hospitals understand the origin of the illness, track its occurrence, or actively work to prevent it, the experts said.

Many cases of NVHAP could be avoided if hospital staffers more dutifully brushed the teeth of bedridden patients, according to a growing body of peer-reviewed research papers. Instead, many hospitals often skip teeth brushing to prioritize other tasks and provide only cheap, ineffective toothbrushes, often unaware of the consequences, said Dr. Dian Baker, a Sacramento (Calif.) State nursing professor who has spent more than a decade studying NVHAP.

“I’ll tell you that today the vast majority of the tens of thousands of nurses in hospitals have no idea that pneumonia comes from germs in the mouth,” Dr. Baker said.

Pneumonia occurs when germs trigger an infection in the lungs. Although NVHAP accounts for most of the cases that occur in hospitals, it historically has not received the same attention as pneumonia tied to ventilators, which is easier to identify and study because it occurs among a narrow subset of patients.

NVHAP, a risk for virtually all hospital patients, is often caused by bacteria from the mouth that gathers in the scummy biofilm on unbrushed teeth and is aspirated into the lungs. Patients face a higher risk if they lie flat or remain immobile for long periods, so NVHAP can also be prevented by elevating their heads and getting them out of bed more often.

According to the National Organization for NV-HAP Prevention, which was founded in 2020, this pneumonia infects about 1 in every 100 hospital patients and kills 15%-30% of them. For those who survive, the illness often extends their hospital stay by up to 15 days and makes it much more likely they will be readmitted within a month or transferred to an intensive care unit.

John McCleary, 83, of Millinocket, Maine, contracted a likely case of NVHAP in 2008 after he fractured his ankle in a fall and spent 12 days in rehabilitation at a hospital, said his daughter, Kathy Day, a retired nurse and advocate with the Patient Safety Action Network.

Mr. McCleary recovered from the fracture but not from pneumonia. Two days after he returned home, the infection in his lungs caused him to be rushed back to the hospital, where he went into sepsis and spent weeks in treatment before moving to an isolation unit in a nursing home.

He died weeks later, emaciated, largely deaf, unable to eat, and often “too weak to get water through a straw,” his daughter said. After contracting pneumonia, he never walked again.

“It was an astounding assault on his body, from him being here visiting me the week before his fall, to his death just a few months later,” Ms. Day said. “And the whole thing was avoidable.”

While experts describe NVHAP as a largely ignored threat, that appears to be changing.

Last year, a group of researchers – including Dr. Giuliano and Dr. Baker, plus officials from the Centers for Disease Control and Prevention, the Veterans Health Administration, and the Joint Commission – published a “call-to-action” research paper hoping to launch “a national health care conversation about NVHAP prevention.”

The COVID-19 vaccination effort in the youngest children has begun much more slowly than the most recent rollout for older children, according to the Centers for Disease Control and Prevention.

Almost 263,000 children under age 5 years were vaccinated in the first 2 weeks after final approval on June 18, compared with the over 3 million children aged 5-11 years who received their first dose during the 2 weeks after approval in early November of 2021, based on CDC data last updated on July 7.

That approval, of course, came between the Delta and Omicron surges, when awareness was higher. The low initial uptake among those under age 5, however, was not unexpected by the Biden administration. “That number in and of itself is very much in line with our expectation, and we’re eager to continue working closely with partners to build on this start,” a senior administration official told ABC News.

With approval of the vaccine occurring after the school year was over, parents’ thoughts have been focused more on vacations and less on vaccinations. “Even before these vaccines officially became available, this was going to be a different rollout; it was going to take more time,” the official explained.
 

Incidence measures continue on different paths

New COVID-19 cases dropped during the latest reporting week (July 1-7), returning to the downward trend that began in late May and then stopped for 1 week (June 24-30), when cases were up by 12.4%, according to the American Academy of Pediatrics and the Children’s Hospital Association.

Children also represent a smaller share of cases, probably because of underreporting. “There has been a notable decline in the portion of reported weekly COVID-19 cases that are children,” the two groups said in their weekly COVID report. Although “cases are likely increasingly underreported for all age groups, this decline indicates that children are disproportionately undercounted in reported COVID-19 cases.”

Other measures, however, have been rising slowly but steadily since the spring. New admissions of patients aged 0-17 years with confirmed COVID, which were down to 0.13 per 100,000 population in early April, had climbed to 0.39 per 100,000 by July 7, the CDC said on its COVID Data Tracker.

Emergency department visits continue to show the same upward trend, despite a small decline in early June. A COVID diagnosis was involved in just 0.5% of ED visits in children aged 0-11 years on March 26, but by July 6 the rate was 4.7%. Increases were not as high among older children: From 0.3% on March 26 to 2.5% on July 6 for those aged 12-15 and from 0.3% to 2.4% for 16- and 17-year-olds, according to the CDC.

A new study confirms the very high risk of hepatocellular carcinoma faced by patients with cirrhosis who have been cured of hepatitis C, a finding the researchers hope will encourage clinicians to communicate risk information to patients and encourage regular HCC screening.

On average, the predicted probability of HCC in cirrhosis patients was 410 times greater than the equivalent probability in the general population, the study team found.

“As the prospect of HCV elimination approaches, a key challenge to the clinical community is the management of those who are cured of HCV but have a residual risk of HCC,” Hamish Innes, PhD, with Public Health Scotland, Glasgow, and colleagues wrote.

“Central to this is ensuring that cured cirrhosis patients understand the risk of HCC and are provided with appropriate surveillance,” they added. 

“Most patients with cirrhosis do not adhere to HCC screening guidelines,” Nina Beri, MD, medical oncologist with New York University Perlmutter Cancer Center, who wasn’t involved in the study, said in an interview.

The “important” finding in this study “should be conveyed to patients, as this may help improve screening adherence rates,” Dr. Beri said.

The study was published online in the American Journal of Gastroenterology.
 

Findings may help promote screening uptake

Dr. Innes and colleagues compared the predicted probability of HCC in 1,803 Scottish adults (mean age, 50 years; 74% male) with cirrhosis and cured hepatitis C to the background risk in the general population of Scotland.

The mean predicted 3-year probability of HCC at the time of sustained viral response (SVR), determined using the aMAP prognostic model, was 3.64% (range, 0.012%-36.12%).

This contrasts with a 3-year HCC probability in the general population ranging from less than 0.0001% to 0.25% depending on demographics.

All patients with cirrhosis – even those at lowest risk – had a higher probability of HCC than the general population, but there was considerable heterogeneity from one patient to the next.

For example, the mean 3-year predicted probability was 18 times higher in the top quintile (9.8%) versus the lowest quintile (0.5%) of risk, the researchers found.

They could not identify a patient subgroup who exhibited a similar HCC risk profile to the general population, as was their hope going into the study.

Dr. Innes and colleagues have developed an online tool that allows clinicians to frame a patient›s 3-year HCC probability against the equivalent probability in the general population.

In the future, they said the scope of the tool could be extended by incorporating general population data from countries beyond Scotland.

“Our hope is that this tool will springboard patient-clinician discussions about HCC risk, and could mitigate low screening uptake,” Dr. Innes and colleagues wrote.
 

Curing HCV doesn’t eliminate risk

Commenting on the study, Nancy Reau, MD, section chief of hepatology at Rush University Medical Center, Chicago, said curing HCV is “very important and significantly reduces risk for complications, but it doesn’t return you to the normal population.”

Dr. Reau’s advice to cirrhosis patients: “Get screened twice a year.”

Dr. Beri said, in addition to conveying this risk to patients, “it is also important to disseminate this information to the community and to primary care practices, particularly as some patients may not currently follow in a specialized liver disease clinic.”

Also weighing in, Amit Singal, MD, chief of hepatology at the University of Texas Southwestern Medical Center, Dallas, said this study highlights that underlying cirrhosis is “the strongest risk factor for the development of HCC.”

In contrast to other cancers, such as breast and colorectal cancer, in which high risk populations can be identified by readily available information such as age and sex, implementation of HCC screening programs requires identification of patients with cirrhosis, Dr. Singal noted.

“Underuse of HCC screening in clinical practice is often related to providers having difficulty at this step in the process and contributes to the high proportion of HCC detected at late stages,” he told this news organization.

“Availability of accurate noninvasive markers of fibrosis will hopefully help with better identification of patients with cirrhosis moving forward,” Dr. Singal said, “although we as hepatologists need to work closely with our primary care colleagues to ensure these tools are used routinely in at-risk patients, such as those with nonalcoholic fatty liver disease, alcohol-associated liver disease, or history of cured (post-SVR) hepatitis C infection.”

The study was supported by the Medical Research Foundation and Public Health Scotland. Dr. Innes, Dr. Beri, Dr. Reau, and Dr. Singal reported no relevant financial relationships.

A new study confirms the very high risk of hepatocellular carcinoma faced by patients with cirrhosis who have been cured of hepatitis C, a finding the researchers hope will encourage clinicians to communicate risk information to patients and encourage regular HCC screening.

On average, the predicted probability of HCC in cirrhosis patients was 410 times greater than the equivalent probability in the general population, the study team found.

As obstacles to hepatitis C treatment uptake were removed, rates of hepatitis-related liver disease in marginalized groups plummeted, according to a new study in Baltimore, published in Annals of Internal Medicine.

A community-based cohort study that follows current and former people who inject drugs (PWID) with hepatitis C documented drastic reductions in liver disease and death as effective oral antivirals became more readily accessible there between 2015 and 2019.

The researchers concluded that hepatitis C elimination targets are achievable. But, they warned, uptake is uneven, and more needs to be done to facilitate treatment.

“[The study] gives us a real-world perspective on what’s happening on the ground, in terms of people getting treated,” said first author Javier Cepeda, PhD, MPH, an assistant professor at the Johns Hopkins Bloomberg School of Public Health, Baltimore, in an interview. “Changing policy, reducing barriers, [and] getting them access to treatment really does have this really important public health benefit.”

“It’s compelling to see these improved outcomes amongst a cohort of people who inject drugs with baseline hep C,” said Maria Corcorran, MD, MPH. Dr. Corcorran, an acting assistant professor for the department of medicine at the University of Washington, was not involved with the study. “It’s just further evidence that we need to really be linking people to care and getting people treated and cured.”

The World Health Organization has called for the disease’s global elimination by 2030. Cure rates top 95%. But, there are so many new cases and so many barriers to detection and treatment that how to develop and roll out a public health response is the most important question in the field, wrote study co-author David L. Thomas, MD, MPH, in a review article in The New England Journal of Medicine.

“Folks who inject drugs ... do well on hep C treatment and have similar rates of sustained virologic response or cure,” said Dr. Corcorran, who runs a low-barrier clinic for people experiencing homelessness.

But, she added, “there are barriers that are still put up to treatment in terms of who can treat and what insurance is going to cover.”
 

A look at a vulnerable population

The authors studied adults enrolled in ALIVE (AIDS Linked to the Intravenous Experience), a cohort study that has recruited current and former PWID in the Baltimore area since 1988.

Participants visit the clinic twice a year for health-related interviews and blood testing, including HIV serology, hepatitis C virus (HCV) antibody and RNA testing, and liver function tests. They are counseled about HCV testing and treatment but do not receive treatment through the study.

Beginning in 2006, researchers added liver stiffness measures (LSMs), a noninvasive measure conducted with transient elastography.

From 2006 to 2019, the authors followed 1,323 ALIVE participants with chronic HCV infection. The primary outcome was LSMs.
 

Less liver disease, fewer deaths

At baseline, participants’ median age was 49 years; 82% of participants were Black individuals, 71% percent were male, and two-thirds were HIV-negative.

Three percent reported receiving hepatitis C treatment in 2014, which increased to 39% in 2019.

Among 10,350 LSMs, 15% showed cirrhosis at baseline in 2006. In 2015, that rose to 19%, but by 2019, it had fallen to 8%.

By definition, 100% had detectable HCV RNA at baseline. In 2015, 91% still did. By 2019, that rate had fallen to 48%.

Undetectable HCV RNA correlated with lower log LSM in adjusted models (P < .001). It also correlated strongly with lower odds of liver cirrhosis, with an adjusted odds ratio of 0.28 (95% confidence interval, 0.17-0.45; P < .001). In addition, it correlated with lower risk for all-cause mortality, with an adjusted hazard ratio of 0.54 (95% CI, 0.38-0.77; P < .001).

Limitations include the fact that, although transient elastography is considered the most valid way to detect cirrhosis in people with hepatitis C, liver stiffness has not been validated as a measure of fibrosis among people with a sustained virologic response.

In addition, ALIVE participants are older and more likely to be African American individuals, compared with the general population of PWID in Baltimore, wrote co-author Shruti H. Mehta, PhD, a professor of epidemiology at Johns Hopkins University, Baltimore, in an email exchange with this news organization. That could affect generalizability.
 

Treatment is crucial

The first direct-acting antiviral (DAA) for hepatitis C was approved in 2011, and an oral fixed-dose combination antiviral was approved in 2014, ushering in treatments with cure rates far exceeding those with interferon-based therapy.

But until recently, Medicaid patients in Maryland seeking DAA therapy for hepatitis C required prior authorization, with initial restrictions related to disease stage, substance use, and provider type, according to Dr. Mehta.

Gradually, those restrictions were lifted, Dr. Mehta added, and all were eliminated by 2019.

Dr. Cepeda urges clinicians to treat patients infected with hepatitis C immediately.

“There are really important implications on both reducing liver disease progression and all-cause mortality,” he said.

“Hep C is just one part of a whole constellation of health care delivery [and] of treating all of the other potential problems that might need to be addressed – especially with people who inject drugs,” Dr. Cepeda added. “Getting them into care is really, really important.”

The study was funded by the National Institutes of Health. Dr. Cepeda and Dr. Corcorran report no relevant financial relationships. Dr. Mehta reports receiving payments or honoraria and travel support from Gilead Sciences, the makers of the oral hepatitis C medication ledipasvir/sofosbuvir (Harvoni), as well as equipment, materials, drugs, medical writing, gifts, or other services from Abbott, which sells hepatitis C diagnostics. Dr. Thomas reports ties to Excision Bio and to Merck DSMB.

A retrospective investigation using medical claims data found no elevated risk of disease flares in patients with immune-mediated inflammatory diseases (IMIDs) who received the recombinant zoster vaccine (RZV), according to research published in Arthritis & Rheumatology.

The authors of the study noted that individuals with IMIDs are at increased risk for herpes zoster and related complications, including postherpetic neuralgia, and that vaccination has been recommended for certain groups of patients with rheumatoid arthritis, inflammatory bowel disease, and psoriasis, by the American College of Rheumatology and other professional organizations for individuals aged 50 and older.

The study investigators used medical claims from IBM MarketScan, which provided data on patients aged 50-64 years, and data from the Centers for Medicare and Medicaid Services’ Medicare on patients aged 65 and older.

They defined presumed flares in three ways: hospitalization/emergency department visits for IMIDs, steroid treatment with a short-acting oral glucocorticoid, or treatment with a parenteral glucocorticoid injection. The investigators conducted a self-controlled case series (SCCS) analysis to examine any temporal link between the RZV and disease flares.

Among enrollees with IMIDs, 14.8% of the 55,654 patients in the MarketScan database and 43.2% of the 160,545 patients in the Medicare database received at least one dose of RZV during 2018-2019. The two-dose series completion within 6 months was 76.6% in the MarketScan group (age range, 50-64 years) and 85.4% among Medicare enrollees (age range, 65 years and older). In the SCCS analysis, 10% and 13% of patients developed flares in the control group as compared to 9%, and 11%-12% in the risk window following one or two doses of RZV among MarketScan and Medicare enrollees, respectively.

Based on these findings, the investigators concluded there was no statistically significant increase in flares subsequent to RZV administration for any IMID in either patients aged 50-64 years or patients aged 65 years and older following the first dose or second dose.

Nilanjana Bose, MD, a rheumatologist with Lonestar Rheumatology, Houston, Texas, who was not involved with the study, said that the research addresses a topic where there is uneasiness, namely vaccination in patients with IMIDs.

They defined presumed flares in three ways: hospitalization/emergency department visits for IMIDs, steroid treatment with a short-acting oral glucocorticoid, or treatment with a parenteral glucocorticoid injection. The investigators conducted a self-controlled case series (SCCS) analysis to examine any temporal link between the RZV and disease flares.

Among enrollees with IMIDs, 14.8% of the 55,654 patients in the MarketScan database and 43.2% of the 160,545 patients in the Medicare database received at least one dose of RZV during 2018-2019. The two-dose series completion within 6 months was 76.6% in the MarketScan group (age range, 50-64 years) and 85.4% among Medicare enrollees (age range, 65 years and older). In the SCCS analysis, 10% and 13% of patients developed flares in the control group as compared to 9%, and 11%-12% in the risk window following one or two doses of RZV among MarketScan and Medicare enrollees, respectively.

Based on these findings, the investigators concluded there was no statistically significant increase in flares subsequent to RZV administration for any IMID in either patients aged 50-64 years or patients aged 65 years and older following the first dose or second dose.

Nilanjana Bose, MD, a rheumatologist with Lonestar Rheumatology, Houston, Texas, who was not involved with the study, said that the research addresses a topic where there is uneasiness, namely vaccination in patients with IMIDs.

A retrospective investigation using medical claims data found no elevated risk of disease flares in patients with immune-mediated inflammatory diseases (IMIDs) who received the recombinant zoster vaccine (RZV), according to research published in Arthritis & Rheumatology.

The Diagnosis: Borrelial Lymphocytoma (Lymphocytoma Cutis)

A punch biopsy revealed an atypical lobular lymphoid infiltrate within the dermis and subcutaneous tissue with a mixed composition of CD3⁺ T cells and CD20⁺ B cells (quiz image, bottom). Immunohistochemical studies revealed a normal CD4:CD8 ratio with preservation of CD5 and CD7. CD30 was largely negative. CD21 failed to detect follicular dendritic cell networks, and κ/λ light chain staining confirmed a preserved ratio of polytypic plasma cells. There was limited staining with B-cell lymphoma (Bcl-2 and Bcl-6). Polymerase chain reaction studies for both T- and B-cell receptors were negative (polyclonal).

Lyme disease is the most frequently reported vectorborne infectious disease in the United States, and borrelial lymphocytoma (BL) is a rare clinical sequela. Borrelial lymphocytoma is a variant of lymphocytoma cutis (also known as benign reactive lymphoid hyperplasia), which is an inflammatory lesion that can mimic malignant lymphoma clinically and histologically. Lymphocytoma cutis is considered the prototypical example of cutaneous B-cell pseudolymphoma.¹ Due to suspicion for lymphocytoma cutis based on the histologic findings and characteristic location of the lesions in our patient, Lyme serologies were ordered and were positive for IgM antibodies against p23, p39, and p41 antigens in high titers. Our patient was treated with doxycycline 100 mg twice daily for 3 weeks with complete resolution of the lesions at 3-month follow-up.

Clinically, BL appears as erythematous papules, plaques, or nodules commonly on the lobules of the ears (quiz image, top). Most cases of lymphocytoma cutis are idiopathic but may be triggered by identifiable associated etiologies including Borrelia burgdorferi, Leishmania donovani, molluscum contagiosum, herpes zoster virus, vaccinations, tattoos, insect bites, and drugs. The main differential diagnosis of lymphocytoma cutis is cutaneous B-cell lymphoma. Pseudolymphoma of the skin can mimic nearly all immunohistochemical staining patterns of true B-cell lymphomas.²

Primary cutaneous follicle center lymphoma frequently occurs on the head and neck. This true lymphoma of the skin can demonstrate prominent follicle centers with centrocytes and fragmented germinal centers (Figure 1) or show a diffuse pattern.³ Most cases show conspicuous Bcl-6 staining, and IgH gene rearrangements can detect a clonal B-cell population in more than 50% of cases.⁴

Diffuse large B-cell lymphoma can occur as a primary cutaneous malignancy or as a manifestation of systemic disease.4 When arising in the skin, lesions tend to affect the extremities, and the disease is classified as diffuse large B-cell lymphoma, leg type. Histologically, sheets of large atypical lymphocytes with numerous mitoses are seen (Figure 2). These cells stain positively with Bcl-2 and frequently demonstrate Bcl-6 and MUM-1, none of which were seen in our case.4 Lymphomatoid papulosis (LyP) tends to present with relapsing erythematous papules. Patients occasionally develop LyP in association with mycosis fungoides or other lymphomas. Both LyP and primary cutaneous anaplastic large cell lymphoma demonstrate conspicuous CD30+ large cells that can be multinucleated or resemble the Reed-Sternberg cells seen in Hodgkin lymphoma (Figure 3).4 Arthropod bite reactions are common but may be confused with lymphomas and pseudolymphomas. The perivascular lymphocytic infiltrate seen in arthropod bite reactions may be dense and usually is associated with numerous eosinophils (Figure 4). Occasional plasma cells also can be seen, and if the infiltrate closely adheres to vascular structures, a diagnosis of erythema chronicum migrans also can be considered. Patients with chronic lymphocytic leukemia/lymphoma may demonstrate exaggerated or persistent arthropod bite reactions, and atypical lymphocytes can be detected admixed with the otherwise reactive infiltrate.⁴

Borrelia burgdorferi is primarily endemic to North America and Europe. It is a spirochete bacterium spread by the Ixodes tick that was first recognized as the etiologic agent in 1975 in Old Lyme, Connecticut, where it received its name.⁵ Most reported cases of Lyme disease occur in the northeastern United States, which correlates with this case given our patient’s place of residence.⁶ Borrelial lymphocytoma cutis occurs in areas endemic for the Ixodes tick in Europe and North America.⁷ When describing the genotyping of Borrelia seen in BL, the strain B burgdorferi previously was grouped with Borrelia afzelii and Borrelia garinii.² In the contemporary literature, however, B burgdorferi is referred to as sensu stricto when specifically talking about the strain B burgdorferi, and the term sensu lato is used when referencing the combination of strains (B burgdorferi, B afzelii, B garinii).

A 2016 study by Maraspin et al⁸ comprising 144 patients diagnosed with BL showed that the lesions mainly were located on the breast (106 patients [73.6%]) and the earlobe (27 patients [18.8%]), with the remaining cases occurring elsewhere on the body (11 patients [7.6%]). The Borrelia strains isolated from the BL lesions included B afzelii, Borrelia bissettii, and B garinii, with B afzelii being the most commonly identified (84.6% [11/13]).⁸

Borrelial lymphocytoma usually is categorized as a form of early disseminated Lyme disease and is treated as such. The treatment of choice for early disseminated Lyme disease is doxycycline 100 mg twice daily for 14 to 21 days. Ceftriaxone and azithromycin are reasonable treatment options for patients who have tetracycline allergies or who are pregnant.⁹

In conclusion, the presentation of red papules or nodules on the ears should prompt clinical suspicion of Lyme disease, particularly in endemic areas. Differentiating pseudolymphomas from true lymphomas and other reactive conditions can be challenging.
