In a specialty dermatology clinic, pediatric lichen sclerosus (LS) was difficult to differentiate from vitiligo, especially in patients with medium to dark skin tones, according to a retrospective review of cases.

Researchers who tallied symptoms and physical exam findings observed fewer statistically significant differences between LS and vitiligo patients than expected, and LS and vitiligo were sometimes misdiagnosed as each other.

“LS must be treated aggressively to prevent long-term sequelae such as permanent scarring and vulvar squamous cell carcinoma, making an accurate diagnosis crucial,” the authors write in a poster they presented at the annual meeting of the Society for Pediatric Dermatology.

The researchers found that pruritus, constipation, and dysuria were the most common symptoms experienced by both LS and vitiligo patients. All were experienced more frequently by LS patients, but only pruritus reached statistical significance (P = .040). Other symptoms experienced only by LS patients included vulvar pain, bleeding, and pain with defecation.

Meanwhile, apart from hypopigmentation and erythema, all physical exam findings were more frequent in LS patients, compared with vitiligo patients, including fissures and purpura/petechiae, but only epidermal atrophy and figure-of-8 distribution of hypopigmentation reached statistical significance (P values of .047 and .036, respectively).

In other findings, LS and vitiligo were misdiagnosed as each other 15 times. Nearly half of the misdiagnoses (46.7%) were made in Black patients, who composed 38.8% of all patients in the study.

“I suspect that some vitiligo cases that were previously ‘misdiagnosed’ as LS were actually LS that just didn’t repigment and then were labeled as vitiligo in the chart,” Dr. Habeshian said.

“And some of those LS cases that previously were misdiagnosed as vitiligo likely had other more subtle LS findings that were missed (shininess and wrinkling of the skin, small fissures, constipation) or that were attributed to comorbid irritant contact dermatitis or another condition,” she said. “It was interesting to see that even in a vulvar dermatology clinic there can be confusion between these diagnoses because the literature on pediatric LS in darker skin tones is so sparse.”

She emphasized that a close exam and detailed history are needed to properly diagnose patients with anogenital skin conditions.

“Don’t forget to ask about constipation and urinary symptoms as well as psychosocial and, in the appropriate patient, sexual and reproductive function,” Dr. Habeshian said. “Based on my experience, pediatric LS is much more common in our community than the literature would suggest. Its psychosocial impact is tremendous but not well documented, particularly in pediatric patients. In my experience, the longer LS is misdiagnosed or mistreated, the more challenging it becomes to manage. You don’t want to miss LS.”

She acknowledged certain limitations of the study, including the fact that photographs were not available for review for many of the earlier years of the clinic. “Therefore, we had to depend on the diagnosis given at the time of the visit,” she said. “This likely accounts in part for the smaller number than expected of significant exam and history findings between LS and vitiligo. We need further studies utilizing a standardized approach to accurate diagnosis.”

Her coauthors were Nikita Menta, Aneka Khilnani, MS, and Tazim Dowlut-McElroy, MD. The researchers reported having no financial disclosures.

COVID-19 hospitalizations continue their steady summer march upward, and now a new variant has perched atop the list of the most prevalent forms of the virus.

Called “Eris” among avid COVID trackers, the strain EG.5 now accounts for 17% of all U.S. COVID infections, according to the latest Centers for Disease Control and Prevention estimates. That’s up from 12% the week prior. 

EG.5 has been rising worldwide, just weeks after the World Health Organization added the strain to its official monitoring list. In the United Kingdom, it now accounts for 1 in 10 COVID cases, The Independent reported.

EG.5 is a descendant of the XBB strains that have dominated tracking lists in recent months. It has the same makeup as XBB.1.9.2 but carries an extra spike mutation, according to a summary published by the Center for Infectious Disease Research and Policy at the University of Minnesota. The spike protein is the part of the virus that allows it to enter human cells. But there’s no indication so far that EG.5 is more contagious or severe than other recent variants, according to the CIDRAP summary and a recent podcast from the American Medical Association. The CDC said that current vaccines protect against the variant.

U.S. hospitals saw a 12% increase in COVID admissions during the week ending on July 22, with 8,047 people being admitted because of the virus, up from an all-time low of 6,306 the week of June 24. In 17 states, the past-week increase in hospitalizations was 20% or greater. In Minnesota, the rate jumped by 50%, and in West Virginia, it jumped by 63%. Meanwhile, deaths reached their lowest weekly rate ever for the week of data ending July 29, with just 176 deaths reported by the CDC.

TOPLINE:

Long-term and recurrent use of antibiotics early in life may raise the risk of early-onset colorectal cancer (CRC) and adenomas, particularly in people with a variant in a specific gut microbiota regulatory gene, a new analysis found.

METHODOLOGY:

• Researchers analyzed data from UK Biobank participants who were recruited between 2006 and 2010 and were followed up to February 2022.
• They evaluated associations between early-life factors and early-onset CRC risk overall, focusing on long-term and recurrent antibiotic use.
• The team also estimated associations between long-term and recurrent antibiotic use in early life and CRC risk by polygenic risk score using 127 CRC-related genetic variants, as well as a particular gut microbiota regulatory gene FUT2.
• Associations for early-onset colorectal adenomas, as precursor to CRC, were also evaluated.
• The study included 113,256 participants. There were 165 early-onset CRC cases and 719 early-onset adenoma cases.

TAKEAWAY:

• Early-life, long-term, and recurrent antibiotic use was “nominally” associated with an increased risk of early-onset CRC (odds ratio, 1.48; P = .046) and adenomas (OR, 1.40; P < .001).
• Regarding variants of FUT2, the risk of early-onset CRC appeared to be greater for individuals with the rs281377 TT genotype (OR, 2.74) in comparison with those with the CT and TT genotypes, but none of the estimates reached statistical significance.
• The researchers found a strong positive association between long-term and recurrent antibiotic use and adenomas, largely in patients with rs281377 TT (OR, 1.75) and CT genotypes (OR, 1.51).
• Individuals with a high polygenic risk score were at higher risk of early-onset CRC (OR, 1.72; P = .019), while those with low polygenic risk scores were not at higher risk (OR, 1.05; P = .889). The association between antibiotic use and early-onset CRC risk by family history was also higher (OR, 2.34).

IN PRACTICE:

“Our findings suggested that individuals with genetic risk factors (i.e., family history of CRC) who have experienced early-life antibiotics use on a long-term basis are probably at increased early-onset CRC risk,” the authors concluded. “Given that antibiotics remain valuable in the management of bacterial infections during early life, investigating the pros and cons of early-life antibiotic use is of great significance.”

SOURCE:

The study, led by Fangyuan Jiang, with Zhejiang University, Hangzhou, China, was published online in the International Journal of Cancer.

LIMITATIONS:

The study relied on participants’ recall of early-life antibiotics use, which could introduce recall bias and misclassification of this exposure.

DISCLOSURES:

No conflicts of interest were reported.

Aggressive marketing of OxyContin in the mid-1990s not only fueled the opioid crisis but also the spread of infectious diseases associated with injection drug use, a new analysis shows.

The uptick in rates of infectious diseases, namely, hepatitis and infective endocarditis, occurred after 2010, when OxyContin maker Purdue Pharma reformulated OxyContin to make it harder to crush and snort. This led many people who were already addicted to the powerful pain pills to move on to injecting heroin or fentanyl, which fueled the spread of infectious disease.

“Our results suggest that the mortality and morbidity consequences of OxyContin marketing continue to be salient more than 25 years later,” write Julia Dennett, PhD, and Gregg Gonsalves, PhD, with Yale University School of Public Health, New Haven, Conn.

Their study was published online in Health Affairs.
 

Long-term effects revealed

Until now, the long-term effects of widespread OxyContin marketing with regard to complications of injection drug use were unknown.

Dr. Dennett and Dr. Gonsalves evaluated the effects of OxyContin marketing on the long-term trajectories of various injection drug use–related outcomes. Using a difference-in-difference analysis, they compared states with high vs. low exposure to OxyContin marketing before and after the 2010 reformulation of the drug.

Before 2010, rates of infections associated with injection drug use and overdose deaths were similar in high- and low-marketing states, they found.

Those rates diverged after the 2010 reformulation, with more infections related to injection drug use in states exposed to more marketing.

Specifically, from 2010 until 2020, high-exposure states saw, on average, an additional 0.85 acute hepatitis B cases, 0.83 hepatitis C cases, and 0.62 cases of death from infective endocarditis per 100,000 residents.

High-exposure states also had 5.3 more deaths per 100,000 residents from synthetic opioid overdose.

“Prior to 2010, among these states, there were generally no statistically significant differences in these outcomes. After 2010, you saw them diverge dramatically,” Dr. Dennett said in a news release.

Dr. Dennett and Dr. Gonsalves say their findings support the view that the opioid epidemic is creating a converging public health crisis, as it is fueling a surge in infectious diseases, particularly hepatitis, infective endocarditis, and HIV.

“This study highlights a critical need for actions to address the spread of viral and bacterial infections and overdose associated with injection drug use, both in the states that were subject to Purdue’s promotional campaign and across the U.S. more broadly,” they add.

Purdue Pharma did not provide a comment on the study.

Funding for the study was provided by the National Institute on Drug Abuse. Disclosures for Dr. Dennett and Dr. Gonsalves were not available.

NEW YORK – When data were combined from two parallel phase 3 bronchiectasis treatment trials, inhaled colistimethate sodium failed to significantly reduce the rate of exacerbations associated with Pseudomonas aeruginosa infection, but the disparity in the findings from the two trials, presented at the 6th World Bronchiectasis & NTM Conference (WBC) 2023, strongly suggests that this therapy is effective after all.

“The totality of the evidence supports a consistent and clinically meaningful benefit [of this therapy] outside of pandemic conditions,” reported Charles Haworth, MD, director, Cambridge Centre for Lung Infection, Royal Papworth Hospital, Cambridge, England.

The key phrase is “outside of pandemic conditions.” PROMIS I, which was fully enrolled before the COVID-19 pandemic descended, associated the inhaled therapy with highly significant benefits. PROMIS II, which was initiated later and enrolled 40% of its participants during the pandemic, did not.

The difference between these two trials, which were essentially identical, was the timing, according to Dr. Haworth. By starting later, PROMIS II caught the onset of the pandemic, which he believes introduced numerous problems that defeated the opportunity to show an advantage for the inhaled antibiotic.

Injectable colistimethate sodium, a decades-old formulation of colistin, is already approved in the United States for gram-negative infections and is considered helpful even in challenging diseases, such as cystic fibrosis. Positive results from a phase 2 trial with inhaled colistimethate sodium in bronchiectasis patients with P. aeruginosa infection provided the rationale for the phase 3 PROMIS program.

The key entry criterion of PROMIS I and PROMIS II, each with nearly 90 participating study sites, was a history of bronchiectasis and ≥ two P. aeruginosa infections requiring oral therapy or ≥ 1 infection requiring intravenous therapy in the prior 12 months. Patients were randomly assigned to receive colistimethate sodium delivered in the proprietary I-neb nebulizer (CMS I-neb) or a matching placebo.

On the primary endpoint of annualized rate of exacerbations, the figures per year were 0.58 for CMS I-neb and 0.95 for placebo in the PROMIS I trial. This produced a rate ratio of 0.65, signaling a significant 35% (P = .00101) reduction in risk. In PROMIS II, the annualized rates of exacerbation were essentially identical in the experimental and control arms (0.089 vs. 0.088; P = .97).

With “no signal of benefit” in the PROMIS II trial, the numerical advantage of CMS I-neb for the combined data did not reach statistical significance, Dr. Haworth reported.

Other endpoints told the same story. For example, the time to first exacerbation was reduced by 41% in PROMIS I (HR, 0.59; P = .0074) but was not reduced significantly (P = .603) in PROMIS II. In PROMIS I, there was a nearly 60% reduction in the risk of severe exacerbations associated with CMS I-neb, but the risk ratio of severe infections was slightly but not significantly higher on CMS I-neb in PROMIS II.

There were signals of benefit in PROMIS II. For example, the reductions in P. aeruginosa density were similar in the two studies (P < .00001 in both), and assessment with the Severe Exacerbations and Quality of Life (SQOL) tool associated CMS I-neb with end-of-study improvement in QOL for the experimental arm in both studies.

While Dr. Haworth acknowledged that he recognizes the “issues of post hoc analysis with any data,” he argued that there is compelling evidence that the pandemic “severely disrupted the conduct of the trial,” obscuring a benefit that would have been otherwise shown.

Besides the dramatic reduction in rates of hospitalization during the pandemic, an obstacle for showing differences in exacerbations, and other COVID-related factors with the potential to skew results, Dr. Haworth also provided several sets of objective data to make his point.

Most importantly, Dr. Haworth and his coinvestigators conducted a meta-analysis that combined data from the phase 2 trial, data from PROMIS I, and data from the patients enrolled in PROMIS II prior to the COVID pandemic. In this analysis the rate ratio for annualized exacerbations was a “pretty impressive” 0.65 favoring CMS I-neb. Moreover, in contrast to data from the PROMIS II patients enrolled during the COVID pandemic, the other three sets of data were “remarkably consistent.”

If PROMIS II data collected from patients enrolled during COVID are compared with the other sets of data, they are “the clear outlier,” he asserted.

Many guidelines in Europe, including those from the European Respiratory Society and the British Thoracic Society, already recommend inhaled colistin in patients with bronchiectasis for the treatment of P. aeruginosa. Although Dr. Haworth believes that the preponderance of controlled data now argue that CMS I-neb is effective as well as safe (adverse events in the experimental and placebo arms of PROMIS I and II were similar), he is not sure what steps will be taken to confirm a benefit to regulatory authorities. According to Dr. Haworth, there are no approved inhaled antibiotics in the United States.

Referring to Zambon, which funded the trials and is developing CMS I-neb, Dr. Haworth said, “This will be a company decision. There are some logistical hurdles to doing another trial.”

Not least of these hurdles is that clinicians and patients already consider inhalational antibiotics in general and inhaled colistin specifically to be effective for several types of infections, including P. aeruginosa, according to Eva Polverino, MD, PhD, a pulmonologist associated with the Hospital Clinic of Barcelona. She said that these drugs are already a standard of care in her own country as well as in many other countries in Europe.

“There has been a loss of equipoise needed to conduct a randomized placebo-controlled trial,” Dr. Polverino said. In her opinion, the U.S. FDA “should start thinking of other pathways to approval.” She thinks that enrollment in a placebo-controlled trial is no longer appropriate.

Dr. Haworth and Dr. Polverino have disclosed no relevant financial relationships.

NEW YORK – When data were combined from two parallel phase 3 bronchiectasis treatment trials, inhaled colistimethate sodium failed to significantly reduce the rate of exacerbations associated with Pseudomonas aeruginosa infection, but the disparity in the findings from the two trials, presented at the 6th World Bronchiectasis & NTM Conference (WBC) 2023, strongly suggests that this therapy is effective after all.

“The totality of the evidence supports a consistent and clinically meaningful benefit [of this therapy] outside of pandemic conditions,” reported Charles Haworth, MD, director, Cambridge Centre for Lung Infection, Royal Papworth Hospital, Cambridge, England.

The key phrase is “outside of pandemic conditions.” PROMIS I, which was fully enrolled before the COVID-19 pandemic descended, associated the inhaled therapy with highly significant benefits. PROMIS II, which was initiated later and enrolled 40% of its participants during the pandemic, did not.

The difference between these two trials, which were essentially identical, was the timing, according to Dr. Haworth. By starting later, PROMIS II caught the onset of the pandemic, which he believes introduced numerous problems that defeated the opportunity to show an advantage for the inhaled antibiotic.

Injectable colistimethate sodium, a decades-old formulation of colistin, is already approved in the United States for gram-negative infections and is considered helpful even in challenging diseases, such as cystic fibrosis. Positive results from a phase 2 trial with inhaled colistimethate sodium in bronchiectasis patients with P. aeruginosa infection provided the rationale for the phase 3 PROMIS program.

Neutropenia and radiological findings affected the presentation and diagnosis of pulmonary mucormycosis in adult patients, based on data from 114 individuals.

Diagnosis of pulmonary mucormycosis (PM), an invasive and potentially life-threatening fungal infection, is often delayed because of its variable presentation, wrote Anne Coste, MD, of La Cavale Blanche Hospital and Brest (France) University Hospital, and colleagues.

Improved diagnostic tools including molecular identification and image-guided lung biopsies are now available in many centers, but relations between underlying conditions, clinical presentations, and diagnostic methods have not been described, they said.

In a study published in the journal Chest, the researchers reviewed data from all cases of PM seen at six hospitals in France between 2008 and 2019. PM cases were based on European Organization for Research and Treatment of Cancer and the National Institute of Allergy and Infectious Diseases Mycoses Study Group (EORTC/MSG) criteria. Diabetes and trauma were included as additional host factors, and positive serum or tissue PCR (serum qPCR) were included as mycological evidence. Participants also underwent thoracic computed tomography (CT) scans.

The most common underlying conditions among the 114 patients were hematological malignancy (49%), allogeneic hematopoietic stem-cell transplantation (21%), and solid organ transplantation (17%).

Among the 40% of the cases that involved dissemination, the most common sites were the liver (48%), spleen (48%), brain (44%), and kidneys (37%).

A review of radiology findings showed consolidation in a majority of patients (58%), as well as pleural effusion (52%). Other findings included reversed halo sign (RHS, 26%), halo sign (24%), vascular abnormalities (26%), and cavity (23%).

Bronchoalveolar lavage (BAL) was present in 46 of 96 patients (50%), and transthoracic lung biopsy was used for diagnosis in 8 of 11 (73%) patients with previous negative BALs.

Seventy patients had neutropenia. Overall, patients with neutropenia were significantly more likely than were those without neutropenia to show an angioinvasive presentation that included both RHS and disease dissemination (P < .05).

In addition, serum qPCR was positive in 42 of 53 patients for whom data were available (79%). Serum qPCR was significantly more likely to be positive in neutropenic patients (91% vs. 62%, P = .02). Positive qPCR was associated with an early diagnosis (P = .03) and treatment onset (P = .01).

Possible reasons for the high rate of disseminated PM in the current study may be the large number of patients with pulmonary involvement, use of body CT data, and availability of autopsy results (for 11% of cases), the researchers wrote in their discussion.

Neutropenia and radiological findings influence disease presentation and contribution of diagnostic tools during PM. Serum qPCR is more contributive in neutropenic patients and BAL examination in nonneutropenic patients. Lung biopsies are highly contributive in case of non-contributive BAL.

The findings were limited by several factors including the retrospective design, the inability to calculate sensitivity and specificity of diagnostic methods, and lack of data on patients with COVID-19, the researchers noted. However, the results provide real-life information for clinicians in centers with current mycological platforms, they concluded.

The study received no outside funding. Dr. Coste had no financial conflicts to disclose.

BALTIMORE – Receiving the first dose of the human papillomavirus (HPV) vaccine at age 9, rather than bundling it with the Tdap and meningitis vaccines, appears to increase the likelihood that children will complete the HPV vaccine series, according to a retrospective cohort study of commercially insured youth presented at the annual clinical and scientific meeting of the American College of Obstetricians and Gynecologists. The research was published ahead of print in Human Vaccines and Immunotherapeutics.

Changing attitudes

“These findings are novel because they emphasize starting at age 9, and that is different than prior studies that emphasize bundling of these vaccines,” Kevin Ault, MD, professor and chair of the department of obstetrics and gynecology at Western Michigan University Homer Stryker MD School of Medicine and a former member of the CDC’s Advisory Committee on Immunization Practices, said in an interview.

Dr. Ault was not involved in the study but noted that these findings support the AAP’s recommendation to start the HPV vaccine series at age 9. The Centers for Disease Control and Prevention currently recommends giving the first dose of the HPV vaccine at ages 11-12, at the same time as the Tdap and meningitis vaccines. This recommendation to “bundle” the HPV vaccine with the Tdap and meningitis vaccines aims to facilitate provider-family discussion about the HPV vaccine, ideally reducing parent hesitancy and concerns about the vaccines. Multiple studies have shown improved HPV vaccine uptake when providers offer the HPV vaccine at the same time as the Tdap and meningococcal vaccines.

However, shifts in parents’ attitudes have occurred toward the HPV vaccine since those studies on bundling: Concerns about sexual activity have receded while concerns about safety remain high. The American Academy of Pediatrics and the American Cancer Society both advise starting the HPV vaccine series at age 9, based on evidence showing that more children complete the series when they get the first shot before age 11 compared to getting it at 11 or 12.

“The bundling was really to vaccinate people by the age of 13, thinking that onset of sexual activity was after that,” study author Sidika Kajtezovic, MD, a resident at Boston Medical Center and Boston University Obstetrics and Gynecology, said in an interview. But Dr. Kajtezovic said she delivers babies for 13-year-old patients. “Kids are having sex sooner or sooner.” It’s also clear that using the bundling strategy is not making up the entire gap right now: Ninety percent of children are getting the meningococcal vaccine while only 49% are getting the HPV vaccine, Dr. Kajtezovic pointed out. “There’s a disconnect happening there, even with the bundling,” she said.
 

Debundling vaccines

Dr. Kajtezovic and her colleagues used a national database of employee-sponsored health insurance to analyze the records of 100,857 children who were continuously enrolled in a plan from age 9 in 2015 to age 13 in 2019. They calculated the odds of children completing the HPV vaccine series based on whether they started the series before, at the same time as, or after the Tdap vaccination.

Youth who received the HPV vaccine before their Tdap vaccine had 38% greater odds of completing the series – getting both doses – than did those who received the HPV vaccine at the same time as the Tdap vaccine. Meanwhile, in line with prior evidence, those who got the first HPV dose after their Tdap were less likely – 68% lower odds – to complete the two- or three-dose (if starting above age 14) series.

The researchers identified several other factors that were linked to completing the HPV vaccine series. Females had greater odds than did males of completing the series, as did those living in urban, rather than rural, areas. Other factors associated with completing the series included living in the Northeast United States and receiving primary care from a pediatrician rather than a family medicine physician.
 

Timing is important

“I am encouraged by the findings of this study,” Dr. Ault said in an interview. “However, I would have liked the authors to expand the age range a bit higher. There are data that continuing to discuss the HPV vaccine with parents and teens will increase uptake into the later teen years.”

One challenge is that research shows attendance at primary care visits declines in older adolescence. Since there is no second Tdap or meningitis shot, families need to return for the second HPV vaccine dose after those shots, though they could get the second dose at the same time as other two vaccines if they receive the first dose before age 11. There’s also evidence suggesting that providers find conversations about the HPV vaccine easier when sexual activity is not the focus.

“I often feel that, before a child reaches adolescence, they’re almost, in a way, not sexualized yet, so talking about cancer prevention for an 8- or 9-year-old sometimes sounds a little different to patients versus protecting your 12-year-old, who’s starting to go through adolescence and developing breasts” and other signs of puberty, Dr. Kajtezovic said. Keeping the focus of HPV vaccine discussions on cancer prevention also allows providers to point out the protection against anal cancer, vulvar cancer, vaginal cancer, and head and neck cancer. “They are horrible, and even if they’re treatable, they’re often very hard to treat at an advanced stage,” Dr. Kajtezovic said. “The surgery required is so life disabling and disfiguring.”

The HPV Roundtable advises continuing bundling at practices having success with it but encourages practices to consider earlier vaccination if their uptake is lagging. Quality improvement initiatives, such as earlier electronic medical record prompts and multi-level interventions in pediatric practices, have shown substantial increases in HPV vaccine uptake at 9 and 10 years old. One survey in 2021 found that one in five primary care providers already routinely recommend the HPV vaccine at ages 9-10, and nearly half of others would consider doing so.

“My hope is in the next few years, when [the CDC] refreshes their vaccine recommendations, that they will either unbundle it or move the bar a few years earlier so that you can initiate it to encourage earlier initiation,” Dr. Kajtezovic said.

Dr. Ault had no other disclosures besides prior service on ACIP. Dr. Kajtezovic had no disclosures.

Dr. Kajtezovic and her colleagues used a national database of employee-sponsored health insurance to analyze the records of 100,857 children who were continuously enrolled in a plan from age 9 in 2015 to age 13 in 2019. They calculated the odds of children completing the HPV vaccine series based on whether they started the series before, at the same time as, or after the Tdap vaccination.

Youth who received the HPV vaccine before their Tdap vaccine had 38% greater odds of completing the series – getting both doses – than did those who received the HPV vaccine at the same time as the Tdap vaccine. Meanwhile, in line with prior evidence, those who got the first HPV dose after their Tdap were less likely – 68% lower odds – to complete the two- or three-dose (if starting above age 14) series.

The researchers identified several other factors that were linked to completing the HPV vaccine series. Females had greater odds than did males of completing the series, as did those living in urban, rather than rural, areas. Other factors associated with completing the series included living in the Northeast United States and receiving primary care from a pediatrician rather than a family medicine physician.
 

Timing is important

“I am encouraged by the findings of this study,” Dr. Ault said in an interview. “However, I would have liked the authors to expand the age range a bit higher. There are data that continuing to discuss the HPV vaccine with parents and teens will increase uptake into the later teen years.”

One challenge is that research shows attendance at primary care visits declines in older adolescence. Since there is no second Tdap or meningitis shot, families need to return for the second HPV vaccine dose after those shots, though they could get the second dose at the same time as other two vaccines if they receive the first dose before age 11. There’s also evidence suggesting that providers find conversations about the HPV vaccine easier when sexual activity is not the focus.

“I often feel that, before a child reaches adolescence, they’re almost, in a way, not sexualized yet, so talking about cancer prevention for an 8- or 9-year-old sometimes sounds a little different to patients versus protecting your 12-year-old, who’s starting to go through adolescence and developing breasts” and other signs of puberty, Dr. Kajtezovic said. Keeping the focus of HPV vaccine discussions on cancer prevention also allows providers to point out the protection against anal cancer, vulvar cancer, vaginal cancer, and head and neck cancer. “They are horrible, and even if they’re treatable, they’re often very hard to treat at an advanced stage,” Dr. Kajtezovic said. “The surgery required is so life disabling and disfiguring.”

The HPV Roundtable advises continuing bundling at practices having success with it but encourages practices to consider earlier vaccination if their uptake is lagging. Quality improvement initiatives, such as earlier electronic medical record prompts and multi-level interventions in pediatric practices, have shown substantial increases in HPV vaccine uptake at 9 and 10 years old. One survey in 2021 found that one in five primary care providers already routinely recommend the HPV vaccine at ages 9-10, and nearly half of others would consider doing so.

“My hope is in the next few years, when [the CDC] refreshes their vaccine recommendations, that they will either unbundle it or move the bar a few years earlier so that you can initiate it to encourage earlier initiation,” Dr. Kajtezovic said.

Dr. Ault had no other disclosures besides prior service on ACIP. Dr. Kajtezovic had no disclosures.

BALTIMORE – Receiving the first dose of the human papillomavirus (HPV) vaccine at age 9, rather than bundling it with the Tdap and meningitis vaccines, appears to increase the likelihood that children will complete the HPV vaccine series, according to a retrospective cohort study of commercially insured youth presented at the annual clinical and scientific meeting of the American College of Obstetricians and Gynecologists. The research was published ahead of print in Human Vaccines and Immunotherapeutics.

Changing attitudes

“These findings are novel because they emphasize starting at age 9, and that is different than prior studies that emphasize bundling of these vaccines,” Kevin Ault, MD, professor and chair of the department of obstetrics and gynecology at Western Michigan University Homer Stryker MD School of Medicine and a former member of the CDC’s Advisory Committee on Immunization Practices, said in an interview.

Dr. Ault was not involved in the study but noted that these findings support the AAP’s recommendation to start the HPV vaccine series at age 9. The Centers for Disease Control and Prevention currently recommends giving the first dose of the HPV vaccine at ages 11-12, at the same time as the Tdap and meningitis vaccines. This recommendation to “bundle” the HPV vaccine with the Tdap and meningitis vaccines aims to facilitate provider-family discussion about the HPV vaccine, ideally reducing parent hesitancy and concerns about the vaccines. Multiple studies have shown improved HPV vaccine uptake when providers offer the HPV vaccine at the same time as the Tdap and meningococcal vaccines.

However, shifts in parents’ attitudes have occurred toward the HPV vaccine since those studies on bundling: Concerns about sexual activity have receded while concerns about safety remain high. The American Academy of Pediatrics and the American Cancer Society both advise starting the HPV vaccine series at age 9, based on evidence showing that more children complete the series when they get the first shot before age 11 compared to getting it at 11 or 12.

“The bundling was really to vaccinate people by the age of 13, thinking that onset of sexual activity was after that,” study author Sidika Kajtezovic, MD, a resident at Boston Medical Center and Boston University Obstetrics and Gynecology, said in an interview. But Dr. Kajtezovic said she delivers babies for 13-year-old patients. “Kids are having sex sooner or sooner.” It’s also clear that using the bundling strategy is not making up the entire gap right now: Ninety percent of children are getting the meningococcal vaccine while only 49% are getting the HPV vaccine, Dr. Kajtezovic pointed out. “There’s a disconnect happening there, even with the bundling,” she said.

The Diagnosis: Mycobacterial Infection

Mycobacterium marinum is a waterborne nontuberculous mycobacterium prevailing in salt water, brackish water, and still or streaming fresh water that infects fish and amphibians worldwide.^1,2 Although first described in 1926 as the organism responsible for the demise of fish in an aquarium in Philadelphia, Pennsylvania, it was not until 1954 that the organism was linked to the cause of infection in humans after it was identified in 80 individuals who had utilized the same swimming pool.¹ Due to its ability to secondarily contaminate aquariums, swimming pools, and rivers, this species can give rise to infection in humans, likely though an impaired skin barrier or points of trauma. It commonly is known as swimming pool or fish tank granuloma.^3,4

Infection by M marinum commonly presents with lesions on the upper extremities, particularly the hands, that appear approximately 2 to 3 weeks following exposure to the organism.² Lesions are categorized as superficial (type 1), granulomatous (type 2), or deep (type 3).¹ Superficial lesions usually are solitary and painless; may exhibit purulent secretions; and consist of papulonodular, verrucose, or ulcerated granulomatous inflammation.¹ These lesions may spread in a sporotrichoidlike pattern or in a linear fashion along lymphatic channels, similar to sporotrichosis. Granulomatous lesions present as solitary or numerous granulomas that typically are swollen, tender, and purulent. Deep lesions are the rarest form and primarily are seen in immunocompromised patients, particularly transplant recipients. Infection can lead to arthritis, tenosynovitis, or osteomyelitis.¹

Mycobacterium marinum infection is diagnosed via tissue biopsy for concomitant histopathologic examination and culture from a nonulcerated area close to the lesion.^1,2 If cultures do not grow, polymerase chain reaction (PCR) or PCR restriction fragment length polymorphism analysis can be conducted. These techniques can exclude other potential diagnoses; however, PCR is unable to provide information on antibiotic susceptibility.1 Biopsy of lesions reveals a nonspecific inflammatory type of reaction within the dermis consisting of lymphocytes, polymorphonuclear cells, and histiocytes.^1,4 Additionally, a granulomatous inflammatory infiltrate resembling tuberculoid granuloma, sarcoidlike granuloma, or rheumatoidlike nodules also may be observed.1 With staining, the acid-fast organisms can be viewed within histiocytes, sometimes demonstrating transverse bands.⁴

The preferred treatment of M marinum infection is antibiotic therapy.² It generally is not recommended to obtain in vitro drug sensitivity testing, as mutational resistance to the commonly utilized drugs is minimal. Microbiologic investigation may be warranted in cases of treatment failure or persistently positive cultures over a period of several months.^1,2 Due to its rarity, no clinical trials exist to guide optimal management of M marinum infection, according to a search of ClinicalTrials.gov. Nonetheless, anecdotal evidence of prior cases can direct the selection of antibiotics. Mycobacterium marinum appears to respond to certain tetracyclines, including minocycline followed by doxycycline. Other options include clarithromycin, clarithromycin in combination with rifampin, rifampin in combination with ethambutol, trimethoprimsulfamethoxazole, and ciprofloxacin.^1,2 Surgical debridement or excision may be indicated, especially in an infection involving deep structures, though recurrences have been reported in some individuals following surgery.^2,4 Nonspecific treatment such as hyperthermic or liquid nitrogen local treatment have been used experimentally with positive outcomes; however, experience with this treatment modality is limited.²

Sarcoidosis is an immune-mediated systemic disorder that most commonly affects the lungs and skin. Histopathology shows sarcoidal granulomas with features similar to M marinum infection. The clinical presentation often is described as red-brown macules or papules affecting the face, rarely with overlying scale or ulceration.⁵ Majocchi granuloma is a dermatophyte fungal infection involving the hair follicles. Although application of topical steroids can worsen the involvement, it commonly displays perifollicular pustules,⁶ which were not seen in our patient. Granuloma annulare is a benign granulomatous disorder that will spontaneously resolve, typically within 2 years of onset. It presents as an annular or arcuate red-brown papule or plaque without overlying scale or ulceration,⁷ unlike the lesion seen in our patient. Cutaneous lymphoma is a malignant lymphoproliferative disease most commonly affecting middle-aged White men. The presentation is variable and may include an ulcerated plaque⁸; the lack of systemic symptoms and notable progression over several years in our patient made this a less likely diagnosis.

Family physicians receive less private insurer reimbursement for the human papillomavirus (HPV) vaccine than do pediatricians, according to a new analysis in Family Medicine.

HPV is the most expensive of all routine pediatric vaccines and the reimbursement by third-party payers varies widely. The concerns about HPV reimbursement often appear on clinician surveys.

This study, led by Yenan Zhu, PhD, who was with the department of public health sciences, college of medicine, Medical University of South Carolina, Charleston, at the time of the research, found that, on average, pediatricians received higher reimbursement ($216.07) for HPV vaccine cost when compared with family physicians ($211.33), internists ($212.97), nurse practitioners ($212.91), and “other” clinicians who administer the vaccine ($213.29) (P values for all comparisons were < .001).

The final sample for this study included 34,247 clinicians.

The net return from vaccine cost reimbursements was lowest for family physicians ($0.34 per HPV vaccine dose administered) and highest for pediatricians ($5.08 per HPV vaccine dose administered).

“Adequate cost reimbursement by third-party payers is a critical enabling factor for clinicians to continue offering vaccines,” the authors wrote.

The authors concluded that “reimbursement for HPV vaccine costs by private payers is adequate; however, return margins are small for nonpediatric specialties.”
 

CDC, AAP differ in recommendations

In the United States, private insurers use the Centers for Disease Control and Prevention vaccine list price as a benchmark.

Overall in this study, HPV vaccine cost reimbursement by private payers was at or above the CDC list price of $210.99 but below the American Academy of Pediatrics recommendations ($263.74). 

The study found that every $1 increment in return was associated with an increase in HPV vaccine doses administered. That was highest for family physicians at 0.08% per dollar.

The modeling showed that changing the HPV vaccine reimbursement to the AAP-recommended level could translate to “an estimated 18,643 additional HPV vaccine doses administrated by pediatricians, 4,041 additional doses by family physicians, and 433 doses by ‘other’ specialties in 2017-2018.”

The authors noted that U.S. vaccination coverage has improved in recent years but initiation and completion rates are lower among privately insured adolescents (4.6% lower for initiation and 2.0% points lower for completion in 2021), compared with adolescents covered under public insurance.

Why the difference among specialties?

Variation in reimbursements might be tied to the ability to negotiate reimbursements for adolescent vaccines, the authors said.

“For instance, pediatricians may be able to negotiate higher cost reimbursement, compared with nonpediatric specialties, given that adolescents constitute a large fraction of their patient volume,” they wrote.

Dr. Zhu and colleagues wrote that it should be noted that HPV vaccine cost reimbursement to family practitioners was considerably less than other specialties and they are barely breaking even though they have the second-highest volume of HPV vaccinations (after pediatricians).

The authors acknowledged that it may not be possible to raise reimbursement to the AAP level, but added that “a reasonable increase that can cover direct and indirect expenses (acquisition cost, storage cost, personnel cost for monitoring inventory, insurance, waste, and lost opportunity costs) will reduce the financial strain on nonpediatric clinicians.” That may encourage clinicians to stock and offer the vaccine.
 

Limitations

The researchers acknowledged several limitations. The models did not account for factors such as vaccination bundling, physicians’ recommendation style or differences in knowledge of the vaccination schedule.

The models were also not able to adjust for whether a clinic had reminder prompts in the electronic health records, the overhead costs of vaccines, or vaccine knowledge or hesitancy on the part of the adolescents’ parents.

Additionally, they used data from one private payer, which limits generalizability.

Researchers identified a sample of adolescents eligible for the HPV vaccine (9-14 years old) enrolled in a large private health insurance plan during 2017-2018. Data from states with universal or universal select vaccine purchasing were excluded. These states included Alaska, Hawaii, Idaho, Maine, Massachusetts, South Dakota, New Hampshire, New Mexico, Rhode Island, Vermont, Washington, Wisconsin, and Wyoming.

The models were also not able to adjust for whether a clinic had reminder prompts in the electronic health records, the overhead costs of vaccines, or vaccine knowledge or hesitancy on the part of the adolescents’ parents.

Additionally, they used data from one private payer, which limits generalizability.

Researchers identified a sample of adolescents eligible for the HPV vaccine (9-14 years old) enrolled in a large private health insurance plan during 2017-2018. Data from states with universal or universal select vaccine purchasing were excluded. These states included Alaska, Hawaii, Idaho, Maine, Massachusetts, South Dakota, New Hampshire, New Mexico, Rhode Island, Vermont, Washington, Wisconsin, and Wyoming.

One coauthor reported receiving a consulting fee from Merck on unrelated projects. Another coauthor has provided consultancy to Value Analytics Labs on unrelated projects. All other authors declared no competing interests.

The Diagnosis: Majocchi Granuloma

Histopathology showed rare follicular-based organisms highlighted by periodic acid–Schiff staining. This finding along with her use of clobetasol ointment on the hands led to a diagnosis of Majocchi granuloma in our patient. Clobetasol and crisaborole ointments were discontinued, and she was started on oral terbinafine 250 mg daily for 4 weeks, which resulted in resolution of the rash.

Majocchi granuloma (also known as nodular granulomatous perifolliculitis) is a perifollicular granulomatous process caused by a dermatophyte infection of the hair follicles. Trichophyton rubrum is the most commonly implicated organism, followed by Trichophyton mentagrophytes and Epidermophyton floccosum, which also cause tinea corporis and tinea pedis.¹ This condition most commonly occurs in women aged 20 to 35 years. Risk factors include trauma, occlusion of the hair follicles, immunosuppression, and use of potent topical corticosteroids in patients with tinea.^2,3 Immunocompetent patients present with perifollicular papules or pustules with erythematous scaly plaques on the extremities, while immunocompromised patients may have subcutaneous nodules or abscesses on any hair-bearing parts of the body.³

Majocchi granuloma is considered a dermal fungal infection in which the disruption of hair follicles from occlusion or trauma allows fungal organisms and keratinaceous material substrates to be introduced into the dermis. The differential diagnosis is based on the types of presenting lesions. The papules of Majocchi granuloma can resemble folliculitis, acne, or insect bites, while nodules can resemble erythema nodosum or furunculosis.⁴ Plaques, such as those seen in our patient, can mimic cellulitis and allergic or irritant contact dermatitis.⁴ Additionally, the plaques may appear annular or figurate, which may resemble erythema gyratum repens or erythema annulare centrifugum.

The diagnosis of Majocchi granuloma often requires fungal culture and biopsy because a potassium hydroxide preparation is unable to distinguish between superficial and invasive dermatophytes.³ Histopathology will show perifollicular granulomatous inflammation. Fungal elements can be detected with periodic acid–Schiff or Grocott-Gomori methenamine-silver staining of the hairs and hair follicles as well as dermal infiltrates.⁴

Topical corticosteroids should be discontinued. Systemic antifungals are the treatment of choice for Majocchi granuloma, as topical antifungals are not effective against deep fungal infections. Although there are no standard guidelines on duration or dosage, recommended regimens in immunocompetent patients include terbinafine 250 mg/d for 4 weeks; itraconazole pulse therapy consisting of 200 mg twice daily for 1 week with 2 weeks off therapy, then repeat the cycle for a total of 2 to 3 pulses; and griseofulvin 500 mg twice daily for 8 to 12 weeks (Table).³ For immunocompromised patients, combination therapy with more than one antifungal may be necessary.
