AI markers can predict progression, survival in prostate cancer

Article Type
Changed

Artificial intelligence (AI)–based Gleason scores correlated with pathologists’ Gleason scores for predicting survival in patients with prostate cancer, according to a cohort-based analysis.

An AI-based Gleason score – derived from 7,267 digitized biopsy slides, pathology reports, and clinical data from patient electronic medical records – was calculated for each of 599 prostate cancer patients.

The AI scores were compared with pathologists’ Gleason scores, which were obtained from pathology reports for each of the patients.

The two scores were “highly correlated,” according to investigators. The area under the curve (AUC) for the 7-year mortality rate was 0.667 for the AI-based scores and 0.659 for the pathologists’ scores.

The investigators also found that markers extracted using AI-based algorithms could predict disease progression in patients with low- and higher-grade disease.

Daphna Laifenfeld, PhD, chief scientific officer of Ibex Medical Analytics in Tel Aviv, reported these results in a poster at the AACR virtual meeting II. Ibex Medical Analytics is the company that developed the AI-based algorithms and Gleason score (the Ibex score).

In addition to comparing the Ibex Gleason scores with pathologists’ scores, Dr. Laifenfeld and colleagues sought to “develop AI markers – computational features extracted from slides using AI-based algorithms – that can predict disease progression in low-, and separately, higher-grade patients.”

Information extracted using the algorithms included Gleason scores; perineural invasion; and other characteristics such as inflammation, high-grade prostatic intraepithelial neoplasia, and atrophy.

“We used data ... to address each aim, analyzing hundreds of patients in each comparison, and employed logistic regression to develop the predictive models,” Dr. Laifenfeld said.

Of the 357 patients evaluated, 180 had low-grade disease, defined by a prebiopsy prostate-specific antigen (PSA) level less than 10 ng/mL (Gleason group 1), and 177 patients had higher-grade disease (Gleason group 2 or higher).

Gleason group 1 patients were considered to have progressed if they developed higher-grade cancer, underwent prostatectomy, or if their cancer had metastasized. Gleason group 2 and above patients were considered to have progressed if their cancer metastasized or if they had a postprostatectomy PSA level greater than 4 ng/ml.

In Gleason group 1 patients, combining multiple features from the pathology report with prebiopsy PSA levels was shown to predict disease progression better than prebiopsy PSA levels alone (AUC, 0.687).

“Importantly, AI markers that combine features automatically extracted by Ibex with prebiopsy PSA levels are even better associated with progression (AUC, 0.748),” Dr. Laifenfeld said.

Similarly, in the Gleason group 2 and above patients, the AI markers that combine Ibex-extracted features with prebiopsy PSA levels were also highly associated with progression (AUC, 0.862 vs. AUC, 0.77 for the non–Ibex-based approach) and can be used for patient stratification, Dr. Laifenfeld said.

“For each patient, we can predict whether or not their disease will progress,” she said. “[T]his type of stratification can then be used to support clinical disease management decisions, and [it can be used] in the course of drug development for patient stratification and trial enrichment strategies.”

Hyperglycemia predicts COVID-19 death even without diabetes

Article Type
Changed

 

Nearly half of hospitalized COVID-19 patients without a prior diabetes diagnosis have hyperglycemia, and the latter is an independent predictor of mortality at 28 days, new research indicates.

The findings, from a retrospective analysis of 605 patients with COVID-19 seen at two hospitals in Wuhan, China, were published online July 10 in Diabetologia by Sufei Wang, of the department of respiratory and critical care medicine, Union Hospital, Tongji Medical College, Huazhong University of Science and Technology, and colleagues.

Several previous studies have demonstrated a link between hyperglycemia and worse outcomes in COVID-19, and at least one diabetes diagnosis, but this is the first to focus specifically on that group of patients.

Wang and colleagues found that a fasting blood glucose of 7.0 mmol/L (126 mg/dL) or greater on admission – present in 45.6% of those without a prior diabetes diagnosis – was an independent predictor of 28-day mortality.

Although A1c data weren’t analyzed, the population is believed to include both individuals with preexisting but undiagnosed diabetes and those without diabetes who have acute stress hyperglycemia.

“Glycemic testing and control should be recommended for all COVID-19 patients even if they do not have preexisting diabetes, as most COVID-19 patients are prone to glucose metabolic disorders,” they emphasized.

“Addressing elevated fasting blood glucose at an early stage can help clinicians better manage the condition and lower the mortality risk of COVID-19 patients,” Wang and colleagues noted.
 

Hyperglycemia predicts COVID-19 death, complications

The study involved consecutive patients with COVID-19 and definitive 28-day outcome and fasting blood glucose measurement on admission to two Wuhan-area hospitals between Jan. 24 to Feb. 10, 2020. A total of 605 patients did not have a previous diabetes diagnosis. They were a median age of 59 years and 53.2% were men.

Just over half, 54.4%, had a fasting blood glucose below 6.1 mmol/L (110.0 mg/dL). The rest had dysglycemia: 16.5% had a fasting blood glucose of 6.1-6.9 mmol/L (110-125 mg/dL), considered the prediabetes range, and 29.1% had a fasting blood glucose of 7 mmol/L (126 mg/dL) or above, the cutoff for diabetes.

“These results indicate that our study included both undiagnosed diabetic patients and nondiabetic patients with hyperglycemia caused by an acute blood glucose disorder,” the authors noted.

Over 28 days of hospitalization, 18.8% (114) of the patients died and 39.2% developed one or more in-hospital complications. 

The authors used the CRB-65 score, which assigns 1 point for each of four indicators – confusion, respiratory rate >30 breaths/min, systolic blood pressure ≤90 mm Hg or diastolic blood pressure ≤60 mm Hg, and age ≥65 years – to assess pneumonia severity.

Just over half, 55.2%, had a CRB-65 score of 0, 43.1% had a score of 1-2, and 1.7% had a score of 3-4.

In multivariable analysis, significant independent predictors of 28-day mortality were age (hazard ratio, 1.02), male sex (HR, 1.75), CRB-65 score 1-2 (HR, 2.68), CRB-65 score 3-4 (HR, 5.25), and fasting blood glucose ≥7.0 mmol/L (HR, 2.30).

Compared with patients with normal glucose (<6.1 mmol/L), 28-day mortality was twice as high (HR, 2.06) for those with a fasting blood glucose of 6.1-6.9 mmol/L and more than threefold higher for ≥7.0 mmol/L (HR, 3.54).

Pneumonia severity also predicted 28-day mortality, with hazard ratios of 4.35 and 13.80 for patients with CRB-65 scores of 1-2 and 3-4, respectively, compared with 0.

Inhospital complications, including acute respiratory distress syndrome or acute cardiac, kidney, or liver injury or cerebrovascular accident, occurred in 14.2%, 7.9%, and 17.0% of those in the lowest to highest fasting blood glucose groups.

Complications were more than twice as common in patients with a fasting blood glucose of 6.1-6.9 mmol/L (HR, 2.61) and four times more common (HR, 3.99) among those with a fasting blood glucose ≥7.0 mmol/L, compared with those with normoglycemia.

The study was supported by the National Natural Science Foundation of China and Major Projects of the National Science and Technology. The authors have reported no relevant financial relationships.

Does obesity reduce drug efficacy in breast cancer?

Article Type
Changed

Obesity has been shown to have an impact on the risk of developing breast cancer and on prognosis. A new study suggests that it may also have an effect on treatment.

A high body mass index (BMI) at the time of breast cancer diagnosis could reduce the efficacy of taxane-based adjuvant chemotherapy, worsening survival outcomes, the study suggests.

That study investigated docetaxel (Taxotere), which is a “lipophilic drug, suggesting that fat present in the body could absorb part of the drug before it can reach the tumor,” commented lead author Christine Desmedt, PhD, of the Laboratory for Translational Breast Cancer Research, Department of Oncology, Leuven, Belgium.

“These results also make us wonder whether other chemotherapy drugs from the same family, like paclitaxel (Taxol), will show the same effect,” she said in a statement.

If follow-up research confirms that the findings are related solely to the pharmacologic characteristics of docetaxel, the results may also apply to its use in other types of cancer, including prostate cancer and lung cancer, she added.

The finding that taxane chemotherapy was less effective in overweight patients “is a provocative observation,” commented Harold Burstein, MD, PhD, an oncologist and clinical investigator at Dana-Farber Cancer Institute and Brigham and Women’s Hospital in Boston, Massachusetts.

“It should be explored in other trials that looked at adding taxanes to standard chemotherapy,” he told Medscape Medical News.
 

Worse outcomes in patients with high BMI

The study, published online in the Journal of Clinical Oncology, was a retrospective reanalysis of data from the phase 3 BIG 2-98 trial.

It shows that overweight and obese patients treated with a chemotherapy regimen based on docetaxel had significantly worse disease-free survival (DFS) and overall survival (OS) compared with lean patients treated with the same chemotherapy regimen.

Conversely, for patients treated with an adjuvant chemotherapy regimen that did not include docetaxel, there was no difference in DFS, OS, or in the rates of distant metastases in regard to BMI.

The finding “highlights a differential response to docetaxel according to BMI, which calls for a body composition–based re-evaluation of the risk-benefit ratio of the use of taxanes in breast cancer,” say the researchers. “These results now must be confirmed in additional series.”

The findings call into question results from earlier randomized clinical trials that did not evaluate the efficacy of most cancer drugs on the basis of patient adiposity, the researchers say.

Desmedt emphasized that more research is needed “before changes in treatment can be implemented.”

Experts approached by Medscape Medical News for comment agreed.

“It is important to remember that breast cancer patients needing chemotherapy should still receive the usual chemotherapy regimens, including taxanes, regardless of their weight or habitus,” commented Burstein, who is also professor of medicine at Harvard University.

These data highlight a persistent disparity in breast cancer outcomes, he told Medscape Medical News. Previous studies have shown that overweight patients often have less favorable outcomes. “There are many contributors to poor health outcomes in people with higher BMI, including concurrent health issues such as diabetes and/or hypertension, and unfortunately, the clear link between socioeconomic status and obesity,” he added.

Megan Kruse, MD, of the department of hematology and medical oncology at the Cleveland Clinic, said she “would not make changes in my treatment recommendations based on this study alone.”

Kruse was surprised that when the analysis was restricted to patients who received a relative dose intensity ≥85% for docetaxel, the same reduced rates of DFS and OS were seen as in patients with a high BMI.

“One may have suspected, based on the overall results, that patients with inferior survival outcomes actually received less chemotherapy due to [the] tendency to cap doses of chemotherapy in patients with high BMIs,” she explained.

“Since this analysis keeps dose intensity in mind, the association between BMI and survival outcomes is stronger in my mind. It does not, however, rule out that there are other confounding factors,” Kruse told Medscape Medical News.

Whether the results can be replicated in other retrospective clinical trials remains to be seen, she commented. Noting that the investigators plan to develop a prospective pharmacokinetics study across the BMI spectrum, Kruse added: “This will be of great interest as we plan curative-intent chemotherapy trials moving forward.”

 

 



Study details

For the current study, the investigators analyzed data from all 2,887 breast cancer patients enrolled in the adjuvant BIG 2-98 trial. They compared the survival outcomes of those who received docetaxel-based chemotherapy with those who received non-docetaxel-based chemotherapy in relation to their BMI. Patients with a BMI of 18.5 to 25 kg/m were classified as lean; patients with a BMI of 25-30 were classified as overweight; and those with a BMI ≥30 were classified as obese.

The researchers also assessed a second-order interaction on the basis of treatment, BMI, and estrogen receptor (ER) status.

The results showed that in the overweight women, compared with lean women, the adjusted hazard ratios (HRs) for DFS and OS were 1.12 (95% CI, 98 – 1.50; P = .21) and 1.27 (95% CI,101 – 1.60; P = .04), respectively. For obese vs lean patients, the HRs for DFS and OS were 1.32 (95% CI, 108 – 162; P = .007) and 1.63 (95% CI, 1.27 – 2.09; P < .001), respectively.

The survival outcomes were similar when only those patients who received a relative dose intensity ≥85% for docetaxel were considered. However, when ER-negative and ER-positive tumors were considered separately, the researchers found evidence of a joint modifying role of BMI and ER status on treatment effect for DFS (adjusted P =.06) and OS (adjusted P = .04).

“[I]t appears that the benefit for docetaxel-based versus nondocetaxel-based treatment could be limited to lean and overweight patients with ER-positive tumors and, possibly, to lean patients with ER-negative tumors…,” Desmedt and colleagues comment.

It may even be possible that docetaxel-based treatment could be detrimental for overweight patients with ER-negative tumors, they note, but warn that these results should be interpreted with caution.

The investigators note that, worldwide, the proportion of women with increased adiposity has been increasing for decades. In Europe, it is estimated that more than 50% of women are overweight and obese. In the United States, almost 64% of women have a BMI >25 kg/mg2.

Previous studies have shown that, in postmenopausal women, a high BMI is associated with a higher risk of developing breast cancer and that, in women who do develop breast cancer, the prognosis is worse. In addition, a recent study demonstrated that increased adiposity can raise the risk for breast cancer in postmenopausal women whose BMI is in the normal range.

The study was funded in part by Fondation Cancer Luxemburg and Associazione Italiana per la Ricerca sul Cancro AIRC. Desmedt has disclosed no relevant financial relationships. A number of study coauthors reported relationships with industry.

The study, published online in the Journal of Clinical Oncology, was a retrospective reanalysis of data from the phase 3 BIG 2-98 trial.

It shows that overweight and obese patients treated with a chemotherapy regimen based on docetaxel had significantly worse disease-free survival (DFS) and overall survival (OS) compared with lean patients treated with the same chemotherapy regimen.

Conversely, for patients treated with an adjuvant chemotherapy regimen that did not include docetaxel, there was no difference in DFS, OS, or in the rates of distant metastases in regard to BMI.

The finding “highlights a differential response to docetaxel according to BMI, which calls for a body composition–based re-evaluation of the risk-benefit ratio of the use of taxanes in breast cancer,” say the researchers. “These results now must be confirmed in additional series.”

The findings call into question results from earlier randomized clinical trials that did not evaluate the efficacy of most cancer drugs on the basis of patient adiposity, the researchers say.

Desmedt emphasized that more research is needed “before changes in treatment can be implemented.”

Experts approached by Medscape Medical News for comment agreed.

“It is important to remember that breast cancer patients needing chemotherapy should still receive the usual chemotherapy regimens, including taxanes, regardless of their weight or habitus,” commented Burstein, who is also professor of medicine at Harvard University.

These data highlight a persistent disparity in breast cancer outcomes, he told Medscape Medical News. Previous studies have shown that overweight patients often have less favorable outcomes. “There are many contributors to poor health outcomes in people with higher BMI, including concurrent health issues such as diabetes and/or hypertension, and unfortunately, the clear link between socioeconomic status and obesity,” he added.

Megan Kruse, MD, of the department of hematology and medical oncology at the Cleveland Clinic, said she “would not make changes in my treatment recommendations based on this study alone.”

Kruse was surprised that when the analysis was restricted to patients who received a relative dose intensity ≥85% for docetaxel, the same reduced rates of DFS and OS were seen as in patients with a high BMI.

“One may have suspected, based on the overall results, that patients with inferior survival outcomes actually received less chemotherapy due to [the] tendency to cap doses of chemotherapy in patients with high BMIs,” she explained.

“Since this analysis keeps dose intensity in mind, the association between BMI and survival outcomes is stronger in my mind. It does not, however, rule out that there are other confounding factors,” Kruse told Medscape Medical News.

Whether the results can be replicated in other retrospective clinical trials remains to be seen, she commented. Noting that the investigators plan to develop a prospective pharmacokinetics study across the BMI spectrum, Kruse added: “This will be of great interest as we plan curative-intent chemotherapy trials moving forward.”

 

 



Study details

For the current study, the investigators analyzed data from all 2,887 breast cancer patients enrolled in the adjuvant BIG 2-98 trial. They compared the survival outcomes of those who received docetaxel-based chemotherapy with those who received non-docetaxel-based chemotherapy in relation to their BMI. Patients with a BMI of 18.5 to 25 kg/m were classified as lean; patients with a BMI of 25-30 were classified as overweight; and those with a BMI ≥30 were classified as obese.

The researchers also assessed a second-order interaction on the basis of treatment, BMI, and estrogen receptor (ER) status.

The results showed that in the overweight women, compared with lean women, the adjusted hazard ratios (HRs) for DFS and OS were 1.12 (95% CI, 98 – 1.50; P = .21) and 1.27 (95% CI,101 – 1.60; P = .04), respectively. For obese vs lean patients, the HRs for DFS and OS were 1.32 (95% CI, 108 – 162; P = .007) and 1.63 (95% CI, 1.27 – 2.09; P < .001), respectively.

The survival outcomes were similar when only those patients who received a relative dose intensity ≥85% for docetaxel were considered. However, when ER-negative and ER-positive tumors were considered separately, the researchers found evidence of a joint modifying role of BMI and ER status on treatment effect for DFS (adjusted P =.06) and OS (adjusted P = .04).

“[I]t appears that the benefit for docetaxel-based versus nondocetaxel-based treatment could be limited to lean and overweight patients with ER-positive tumors and, possibly, to lean patients with ER-negative tumors…,” Desmedt and colleagues comment.

It may even be possible that docetaxel-based treatment could be detrimental for overweight patients with ER-negative tumors, they note, but warn that these results should be interpreted with caution.

The investigators note that, worldwide, the proportion of women with increased adiposity has been increasing for decades. In Europe, it is estimated that more than 50% of women are overweight and obese. In the United States, almost 64% of women have a BMI >25 kg/mg2.

Previous studies have shown that, in postmenopausal women, a high BMI is associated with a higher risk of developing breast cancer and that, in women who do develop breast cancer, the prognosis is worse. In addition, a recent study demonstrated that increased adiposity can raise the risk for breast cancer in postmenopausal women whose BMI is in the normal range.

The study was funded in part by Fondation Cancer Luxemburg and Associazione Italiana per la Ricerca sul Cancro AIRC. Desmedt has disclosed no relevant financial relationships. A number of study coauthors reported relationships with industry.

Obesity has been shown to have an impact on the risk of developing breast cancer and on prognosis. A new study suggests that it may also have an effect on treatment.

A high body mass index (BMI) at the time of breast cancer diagnosis could reduce the efficacy of taxane-based adjuvant chemotherapy, worsening survival outcomes, the study suggests.

That study investigated docetaxel (Taxotere), which is a “lipophilic drug, suggesting that fat present in the body could absorb part of the drug before it can reach the tumor,” commented lead author Christine Desmedt, PhD, of the Laboratory for Translational Breast Cancer Research, Department of Oncology, Leuven, Belgium.

“These results also make us wonder whether other chemotherapy drugs from the same family, like paclitaxel (Taxol), will show the same effect,” she said in a statement.

If follow-up research confirms that the findings are related solely to the pharmacologic characteristics of docetaxel, the results may also apply to its use in other types of cancer, including prostate cancer and lung cancer, she added.

The finding that taxane chemotherapy was less effective in overweight patients “is a provocative observation,” commented Harold Burstein, MD, PhD, an oncologist and clinical investigator at Dana-Farber Cancer Institute and Brigham and Women’s Hospital in Boston, Massachusetts.

“It should be explored in other trials that looked at adding taxanes to standard chemotherapy,” he told Medscape Medical News.

FDA expands Dysport use for cerebral palsy–related spasticity

Article Type
Changed

The Food and Drug Administration has approved expanded use of Dysport to treat upper- and lower-limb spasticity – including that caused by cerebral palsy – for patients as young as 2 years and older, according to manufacturer Ipsen Biopharmaceuticals.

When Dysport (abobotulinumtoxinA) initially was approved for treating pediatric lower limb spasticity by the FDA in 2016, Ipsen was granted Orphan Drug exclusivity for children whose lower-limb spasticity was caused by cerebral palsy. In 2019, Dysport was approved by the FDA for treating of upper-limb spasticity in children 2 years older. But if that spasticity was caused by cerebral palsy, Dysport could be used to treat it only through Orphan Drug exclusivity granted to another manufacturer, according to an Ipsen press release.

“The proactive step to resolve the uncertainty created by the previous CP [cerebral palsy] carve out enables us as physicians to prescribe consistent therapy for pediatric patients experiencing both upper- and lower-limb spasticity,” Sarah Helen Evans, MD, division chief of rehabilitation medicine in the department of pediatrics at the Children’s Hospital of Philadelphia, said in the press release.

The most common adverse effects among children with lower-limb spasticity treated with Dysport were nasopharyngitis, cough, and pyrexia. Among children with upper-limb spasticity, the most common effects associated with Dysport treatment were upper respiratory tract infection and pharyngitis.

The press release also included a warning of the distant spread of the botulinum toxin from the area of injection hours to weeks afterward, causing symptoms including blurred vision, generalized muscle weakness, and swallowing and breathing difficulties that can be life threatening; there have been reports of death.

Suspected adverse effects can be reported to the FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.

Subcutaneous nemolizumab eases itching for atopic dermatitis

Article Type
Changed

Adding subcutaneous nemolizumab to topical treatments for atopic dermatitis patients significantly improved their itching, compared with a placebo, in a phase 3 study of 215 patients in Japan.

Controlling the pruritus associated with atopic dermatitis (AD) can have a significant impact on patients’ quality of life, wrote Kenji Kabashima, MD, PhD, of the department of dermatology at Kyoto University, and coauthors. Frequent scratching can cause not only mechanical skin damage, but also may enhance inflammatory reactions and contribute to sleep problems.

In earlier phase studies, nemolizumab, a humanized monoclonal antibody against interleukin-31 receptor A, showed efficacy in reducing pruritus in patients with AD, but has not been well studied in patients who are also using topical agents, they wrote.

In the study published in the New England Journal of Medicine, the researchers randomized 143 patients with AD and moderate to severe pruritus to 60 mg of subcutaneous nemolizumab and 72 patients to a placebo every 4 weeks for 16 weeks. All patients were aged 13 years and older with a confirmed AD diagnosis and a history of inadequate response to or inability to use treatments, including topical glucocorticoids and oral antihistamines. Their average age was 40 years, approximately two-thirds were male, and the average disease duration was approximately 30 years. Topical treatments included a medium potency glucocorticoid in 97% of patients in both groups, and a topical calcineurin inhibitor in 41% of those on nemolizumab, and 40% of those on placebo; almost 90% of the patients in both groups were on oral antihistamines.

At 16 weeks, scores on the visual analog scale for pruritus (the primary outcome) significantly improved from baseline in the nemolizumab group, compared with the placebo group (a mean change of –42.8% and –21.4%, respectively, P < .001).

In addition, more patients in the nemolizumab group, compared with the placebo group (40% vs. 22%) achieved a score of 4 or less on the Dermatology Life Quality Index, with lower scores reflecting less impact of disease on daily life. In addition, more patients in the nemolizumab group, compared with the placebo group (55% vs. 21%) achieved a score of 7 or less on the Insomnia Severity Index.

During the study, 71% of the patients in each group reported adverse events, most were mild or moderate. The most common adverse event was worsening AD, reported by 24% of the nemolizumab patients and 21% of the placebo patients. Reactions related to the injection occurred in 8% of nemolizumab patients and 3% of placebo patients. Cytokine abnormalities, which included an increased level of thymus and activation regulated chemokine, were reported in 10 (7%) of the patients on nemolizumab, none of which occurred in those on placebo. “Most were not accompanied by a worsening of signs of or the extent of atopic dermatitis,” the authors wrote.



Severe adverse events were reported in three patients (2%) in the nemolizumab group, which were Meniere’s disease, acute pancreatitis, and AD in one patient each. No severe adverse events were reported in the placebo group. In addition, three patients in the nemolizumab group experienced four treatment-related adverse events that led them to discontinue treatment: AD, Meniere’s disease, alopecia, and peripheral edema.

The study findings were limited by several factors including the relatively short treatment period, inclusion only of Japanese patients, inclusion of patients aged as young as 13 years, and the inability to draw conclusions from the secondary endpoints such as quality of life and sleep issues, the researchers noted.

However, the results suggest that “nemolizumab plus topical agents may ameliorate both pruritus and signs of eczema and may lessen the severity of atopic dermatitis by disrupting the itch-scratch cycle,” they added.

“Novel therapies [for AD] are needed, as there are still patients who need better disease control despite current therapies, and AD is a heterogeneous disease that may need different treatment approaches,” Eric Simpson, MD, professor of dermatology at Oregon Health & Science University, Portland, said in an interview.

Dr. Simpson, who was not an investigator in this study, said that he was somewhat surprised that the itch reduction was lower in the current study, compared with previous studies by the same group. Also surprising was the increase in cytokine abnormalities in the nemolizumab group, which “needs further study.”

Overall, the data “provide support that blockade of the IL-31 receptor improves itch in AD and appears to have some effect on inflammation,” Dr. Simpson said.

One challenge to the clinical use of nemolizumab will be identifying “where this type of drug fits into the treatment paradigm,” and determining whether specific patients whose disease is driven more by this neuroimmune pathway could benefit more than with the traditional IL-4 or IL-13 blockade, he said.

The study was supported by Maruho. Dr. Kabashima disclosed consulting fees from Maruho and two coauthors were Maruho employees. Dr. Simpson had no financial conflicts relevant to this study, but he reported receiving research grants and other financial relationships with manufacturers of AD therapies.

Infants around the world with bronchiolitis received excess tests despite guidelines

Article Type
Changed

 

While guidelines for bronchiolitis aim to reduce gratuitous tests and treatments, one-third of infants presenting at EDs with bronchiolitis receive an unnecessary intervention, according to a new global study.

For infants with symptoms of bronchiolitis, viral testing, blood tests, and chest x-rays are discouraged in most cases. Antibiotics are not recommended as treatment.

In a study published in Pediatrics, Amy Zipursky, MD, of the Hospital for Sick Children and the University of Toronto, and colleagues, reviewed records for 2,359 infants aged 2-11 months diagnosed with bronchiolitis during the year 2013. The data came from a network of 38 EDs in the Australia, Canada, Ireland, New Zealand, Portugal, Spain, the United Kingdom, and the United States.

Dr. Zipursky and colleagues found that, while 8% of infants in the cohort had been treated with antibiotics, 33% had received at least one nonrecommended test, with rates ranging widely across regions. In the United Kingdom and Ireland, for example, only 15% received such a test, compared with 50% in Spain and Portugal.

Of the children given antibiotics, two-thirds had suspected bacterial infections, the researchers found. Antibiotic use was highest in the United States, at 11% of infants seen for bronchiolitis, and lowest in the United Kingdom and Ireland at 4%. Administration of chest x-rays – which occurred in nearly a quarter of the cohort – increased the likelihood of antibiotics being administered (odds ratio, 2.29; 95% confidence interval, 1.62-3.24) independent of fever or severe symptoms.

The most common nonrecommended tests performed in the study were:

  • Nasopharyngeal viral testing without admission to hospital (n = 591).
  • Chest x-ray without ICU admission (n = 507).
  • Complete blood counts (n = 222).
  • Blood cultures (n = 129).
  • Urinalysis in the absence of fever (n = 86).
  • Febrile infants 3 months of age or less had blood cultures (n = 49).

In some treatment centers the rate of nonrecommended tests performed was 6%, while others saw rates of 74%.

“Despite the evidence that laboratory testing rarely impacts bronchiolitis management and that bacterial infections in bronchiolitis are uncommon, our study reveals that these tests continue to be performed frequently in many parts of the world,” Dr. Zipursky and colleagues wrote in their analysis.

“Plausible reasons may include ‘automatic’ blood draws with intravenous placement, uncertainty about institutional policies, perceived need for reassurance about the diagnosis, perception of ‘doing something,’ and parental desire for a viral label,” the authors surmised. “Because parental pressure to provide interventions may be a driver of care in infants with bronchiolitis in some countries, ED clinicians need to have higher confidence in the evidence-based bronchiolitis care and convey this trust to families.”

The researchers listed among the weaknesses of their study its retrospective design, and that results from x-rays and lab tests performed were not available.

In an editorial comment accompanying the study, Joseph J. Zorc, MD, of Children’s Hospital of Philadelphia and the University of Pennsylvania in Philadelphia, noted that some of the regional differences seen in the study may be attributable to different clinical criteria used to diagnose bronchiolitis. In the United Kingdom, for example, national guidelines include the presence of crackles, while in North America guidelines focus on wheeze. “Perhaps clinicians in the United Kingdom accept the presence of crackles as an expected finding in infant with bronchiolitis and are less likely to order imaging,” Dr. Zorc said (Pediatrics. 2020 Jul 13;146[2]:e20193684).

He also pointed out that the coronavirus pandemic caused by SARS-CoV-2 (COVID- 19) could have an impact on global testing and treatment practices for bronchiolitis, as coronaviruses are a known cause of bronchiolitis. The Pediatric Emergency Research Network, comprising the 38 EDs from which Dr. Zipursky and colleagues drew their data, is conducting a prospective study looking at pediatric disease caused by SARS-CoV-2.

The “collaboration of international networks of pediatric emergency providers is an encouraging sign of potential opportunities to come ... [providing] an opportunity to evaluate variation that can lead to innovation,” Dr. Zorc concluded.

Dr. Zipursky and colleagues reported no external funding or relevant financial disclosures. Dr. Zorc reported no relevant conflicts of interest.

Influenza vaccine efficacy called undiminished in MS

Article Type
Changed

 

The efficacy of the influenza vaccine when given to patients with multiple sclerosis (MS) is similar to that in healthy controls, Jackie Nguyen reported at the virtual annual meeting of the Consortium of Multiple Sclerosis Centers (CMSC). She presented a systematic review and meta-analysis of nine published cohort studies including 417 MS patients and more than 500 healthy controls, all of whom received inactivated seasonal influenza vaccine.

The impetus for this project was a recognition that the great majority of the research on the impact of influenza vaccine in patients with MS has focused on safety and MS relapse rates. In contrast, the nine studies included in the meta-analysis contained data on influenza vaccine efficacy as reflected in the ability to mount an adequate immune response. This was defined in standard fashion either by seroconversion, which required at least a fourfold increase in antibody titers following vaccination, or seroprotection, with a postvaccination antihemagglutination immunoglobulin G titer of at least 40. The analysis included patients with MS irrespective of disease duration or severity or treatment regimen, noted Ms. Nguyen, a third-year medical student at Nova Southeastern University College of Allopathic Medicine in Davie, Fla.

The researchers found that there was no significant difference between patients with MS and healthy controls in the rates of an adequate immune response for influenza H1N1, H3N2, or influenza B virus. “The vaccine should thus continue to be recommended for MS patients, as the data shows it to be efficacious,” she said.

Her conclusion is consistent with guidance provided in the American Academy of Neurology’s 2019 practice guideline update on immunization in MS, highlighted elsewhere at CMSC 2020 in a presentation by Marijean Buhse, PhD, of Stony Brook University in New York.

The guideline, updated for the first time in 17 years, states that all MS patients should be advised to receive influenza vaccine annually: “With known risks of exacerbation and other morbidity with influenza infection and no identified risks of exacerbation with influenza vaccines, benefits of influenza vaccination outweigh the risks in most scenarios. The exception involves the relatively few MS patients having a specific contraindication to the influenza vaccine, such as a previous severe reaction, noted Dr. Buhse, who wasn’t involved in developing the evidence-based guidelines.

The available evidence indicates that some but not all disease-modifying therapies for MS reduce the effectiveness of vaccination against influenza.

According to the guideline, “it is possible” that persons with MS being treated with glatiramer acetate have a reduced likelihood of seroprotection from influenza vaccine, a conclusion the guidelines committee drew with “low confidence in the evidence.” Further, the guideline states that “it is probable” MS patients on fingolimod have a lower likelihood of obtaining seroprotection from influenza vaccine than patients not on the drug, with moderate confidence in the evidence. Also, it is deemed probable that patients with MS who are taking mitoxantrone have a reduced likelihood of response to influenza vaccination, compared with healthy controls. But it is probable that patients with MS who are receiving interferon-beta have no diminution in the likelihood of seroprotection. According to the guideline, there is insufficient evidence to say whether patients with MS who are on natalizumab, teriflunomide, or methotrexate have a diminished response to influenza vaccination.

Dr. Buhse noted that rituximab is off-label therapy for MS, so there are no data available regarding the likelihood of seroprotection in response to influenza vaccination in that setting. However, rituximab profoundly decreases the immunogenicity of influenza and pneumococcal vaccines in rheumatoid arthritis patients. It is therefore recommended that inactivated influenza vaccine be given to patients with MS at least 2 weeks prior to starting rituximab or 6 months after the last dose in order to optimize the humoral results. Ms. Nguyen reported having no financial conflicts regarding her presentation. Dr. Buhse reported having received honoraria from Genzyme and Biogen.

More proof that fruit, vegetables, whole grains may stop diabetes

Article Type
Changed

Two studies published this week in BMJ provide support for eating more fruits, vegetables, and whole grain foods to lower the risk of developing diabetes.

In a pooled analysis of three large prospective American cohorts, people with the highest versus lowest total consumption of whole grain foods had a significantly lower risk of type 2 diabetes.

“These findings provide further support for the current recommendations of increasing whole grain consumption as part of a healthy diet for the prevention of type 2 diabetes,” wrote the authors led by Yang Hu, a doctoral student at Harvard School of Public Health, Boston.

Similarly, in a large European case-cohort study, people with higher values for plasma vitamin C and carotenoids (fruit and vegetable intake) had a lower incidence of type 2 diabetes.

“This study suggests that even a modest increase in fruit and vegetable intake could help to prevent type 2 diabetes ... regardless of whether the increase is among people with initially low or high intake,” wrote Ju-Sheng Zheng, PhD, University of Cambridge (England), and colleagues.
 

Individual whole grain foods

Previous studies have shown that high consumption of whole grains is associated with a lower risk of developing chronic diseases, including type 2 diabetes, cardiovascular disease, obesity, and some types of cancer, Mr. Hu and colleagues wrote.

Although research has shown that whole grain breakfast cereal and brown rice are linked with a lower risk of type 2 diabetes, the effect of other commonly consumed whole grain foods – which contain different amounts of dietary fiber, antioxidants, magnesium, and phytochemicals – has not been established.

Mr. Hu and colleagues analyzed pooled data from 158,259 U.S. women who participated in the Nurses’ Health Study (1984-2014) or the Nurses’ Health Study II (1991-2017) and 36,525 U.S. men who took part in the Health Professionals Follow-Up Study (1986-2016), who were free of diabetes, cardiovascular disease, and cancer.

Participants’ baseline consumption of seven types of whole grain foods – whole grain breakfast cereal, oatmeal, dark bread, brown rice, added bran, wheat germ, and popcorn – was based on self-replies to food frequency questionnaires.

During an average 24-year follow-up, 18,629 participants developed type 2 diabetes.

After adjusting for body mass index, lifestyle, and dietary risk factors, participants in the highest quintile of total whole grain consumption had a 29% lower risk of incident type 2 diabetes than those in the lowest quintile.

The most commonly consumed whole grain foods were whole grain cold breakfast cereal, dark bread, and popcorn.

Compared with eating less than one serving a month of whole grain cold breakfast cereal or dark bread, eating one or more servings a day was associated with a 19% and 21% lower risk of developing diabetes, respectively.

For popcorn, a J-shaped association was found for intake, where the risk of type 2 diabetes was not significantly raised until consumption exceeded about one serving a day, which led to about an 8% increased risk of developing diabetes – likely related to fat and sugar added to the popcorn, the researchers wrote.

For the less frequently consumed whole grain foods, compared with eating less than one serving a month of oatmeal, brown rice, added bran, or wheat germ, participants who ate two or more servings a week had a 21%, 12%, 15%, and 12% lower risk of developing type 2 diabetes, respectively.

Lean or overweight individuals had a greater decreased risk of diabetes with increased consumption of whole grain foods; however, because individuals with obesity have a higher risk of diabetes, even a small decrease in risk is still meaningful.

Limitations include the study was observational and may have had unknown confounders, and the results may not be generalizable to other populations, the authors note.
 

 

 

‘Five a day’ fruits and vegetables

Only one previous small published study from the United Kingdom has examined how blood levels of vitamin C and carotenoids are associated with incident type 2 diabetes, Dr. Zheng and colleagues wrote.

They investigated the relationship in 9,754 adults who developed new-onset type 2 diabetes and a comparison group of 13,662 adults who remained diabetes free during an average 9.7-year follow-up, from 340,234 participants in the European Prospective Investigation Into Cancer and Nutrition–InterAct study.

Participants were from Denmark, France, Germany, Italy, the Netherlands, Spain, Sweden, and the United Kingdom, and incident type 2 diabetes occurred between 1991 and 2007.

The researchers used high-performance liquid chromatography–ultraviolet methods to determine participants’ plasma levels of vitamin C and six carotenoids (alphta-carotene, beta-carotene, lycopene, lutein, zeaxanthin, beta-cryptoxanthin), which they used to calculate a composite biomarker score.

The recommendation to eat at least five fruits and vegetables a day corresponds to eating ≥400 g/day, according to Dr. Zheng and colleagues. The self-reported median fruit and vegetable intake in the current study was 274, 357, 396, 452, and 508 g/day from lowest to highest quintile.

After multivariable adjustment, higher levels of plasma vitamin C and carotenoids were associated with an 18% and 25% lower risk of incident type 2 diabetes per standard deviation, respectively.

Compared with patients whose vitamin C and carotenoid composite biomarker scores were in the lowest 20%, those with scores in the top 20% had half the risk of incident diabetes. Increasing fruit and vegetable consumption by 66 g/day was associated with a 25% lower risk of developing diabetes.

“These findings provide strong evidence from objectively measured biomarkers for the recommendation that fruit and vegetable intake should be increased to prevent type 2 diabetes,” according to the researchers.

However, consumption of fruits and vegetables remains far below guideline recommendations, they observed. “Although five portions a day of fruit and vegetables have been recommended for decades, in 2014-2015, 69% of U.K. adults ate fewer than this number, and this proportion is even higher in European adults (86%).”

Dr. Zheng and colleagues acknowledged that study limitations include those that are inherent with observational studies.

Although they could not distinguish between juice, fortified products, or whole foods, the analyses “were adjusted for vitamin supplement use, and suggest that as biomarkers of fruit and vegetable intake these findings endorse the consumption of fruit and vegetables, not that of supplements,” they maintained.

The study by Mr. Hu and colleagues was funded by the National Institutes of Health. The InterAct project was funded by the EU FP6 program. Biomarker measurements for vitamin C and carotenoids were funded by the InterAct project, EPIC-CVD project, MRC Cambridge Initiative, European Commission Framework Program 7, European Research Council, and National Institute for Health Research. Dr. Zheng has reported receiving funding from Westlake University and the EU Horizon 2020 program.

Similarly, in a large European case-cohort study, people with higher values for plasma vitamin C and carotenoids (fruit and vegetable intake) had a lower incidence of type 2 diabetes.

“This study suggests that even a modest increase in fruit and vegetable intake could help to prevent type 2 diabetes ... regardless of whether the increase is among people with initially low or high intake,” wrote Ju-Sheng Zheng, PhD, University of Cambridge (England), and colleagues.
 

Individual whole grain foods

Previous studies have shown that high consumption of whole grains is associated with a lower risk of developing chronic diseases, including type 2 diabetes, cardiovascular disease, obesity, and some types of cancer, Mr. Hu and colleagues wrote.

Although research has shown that whole grain breakfast cereal and brown rice are linked with a lower risk of type 2 diabetes, the effect of other commonly consumed whole grain foods – which contain different amounts of dietary fiber, antioxidants, magnesium, and phytochemicals – has not been established.

Mr. Hu and colleagues analyzed pooled data from 158,259 U.S. women who participated in the Nurses’ Health Study (1984-2014) or the Nurses’ Health Study II (1991-2017) and 36,525 U.S. men who took part in the Health Professionals Follow-Up Study (1986-2016), who were free of diabetes, cardiovascular disease, and cancer.

Participants’ baseline consumption of seven types of whole grain foods – whole grain breakfast cereal, oatmeal, dark bread, brown rice, added bran, wheat germ, and popcorn – was based on self-replies to food frequency questionnaires.

During an average 24-year follow-up, 18,629 participants developed type 2 diabetes.

After adjusting for body mass index, lifestyle, and dietary risk factors, participants in the highest quintile of total whole grain consumption had a 29% lower risk of incident type 2 diabetes than those in the lowest quintile.

The most commonly consumed whole grain foods were whole grain cold breakfast cereal, dark bread, and popcorn.

Compared with eating less than one serving a month of whole grain cold breakfast cereal or dark bread, eating one or more servings a day was associated with a 19% and 21% lower risk of developing diabetes, respectively.

For popcorn, a J-shaped association was found for intake, where the risk of type 2 diabetes was not significantly raised until consumption exceeded about one serving a day, which led to about an 8% increased risk of developing diabetes – likely related to fat and sugar added to the popcorn, the researchers wrote.

For the less frequently consumed whole grain foods, compared with eating less than one serving a month of oatmeal, brown rice, added bran, or wheat germ, participants who ate two or more servings a week had a 21%, 12%, 15%, and 12% lower risk of developing type 2 diabetes, respectively.

Lean or overweight individuals had a greater decreased risk of diabetes with increased consumption of whole grain foods; however, because individuals with obesity have a higher risk of diabetes, even a small decrease in risk is still meaningful.

Limitations include the study was observational and may have had unknown confounders, and the results may not be generalizable to other populations, the authors note.
 

 

 

‘Five a day’ fruits and vegetables

Only one previous small published study from the United Kingdom has examined how blood levels of vitamin C and carotenoids are associated with incident type 2 diabetes, Dr. Zheng and colleagues wrote.

They investigated the relationship in 9,754 adults who developed new-onset type 2 diabetes and a comparison group of 13,662 adults who remained diabetes free during an average 9.7-year follow-up, from 340,234 participants in the European Prospective Investigation Into Cancer and Nutrition–InterAct study.

Participants were from Denmark, France, Germany, Italy, the Netherlands, Spain, Sweden, and the United Kingdom, and incident type 2 diabetes occurred between 1991 and 2007.

The researchers used high-performance liquid chromatography–ultraviolet methods to determine participants’ plasma levels of vitamin C and six carotenoids (alphta-carotene, beta-carotene, lycopene, lutein, zeaxanthin, beta-cryptoxanthin), which they used to calculate a composite biomarker score.

The recommendation to eat at least five fruits and vegetables a day corresponds to eating ≥400 g/day, according to Dr. Zheng and colleagues. The self-reported median fruit and vegetable intake in the current study was 274, 357, 396, 452, and 508 g/day from lowest to highest quintile.

After multivariable adjustment, higher levels of plasma vitamin C and carotenoids were associated with an 18% and 25% lower risk of incident type 2 diabetes per standard deviation, respectively.

Compared with patients whose vitamin C and carotenoid composite biomarker scores were in the lowest 20%, those with scores in the top 20% had half the risk of incident diabetes. Increasing fruit and vegetable consumption by 66 g/day was associated with a 25% lower risk of developing diabetes.

“These findings provide strong evidence from objectively measured biomarkers for the recommendation that fruit and vegetable intake should be increased to prevent type 2 diabetes,” according to the researchers.

However, consumption of fruits and vegetables remains far below guideline recommendations, they observed. “Although five portions a day of fruit and vegetables have been recommended for decades, in 2014-2015, 69% of U.K. adults ate fewer than this number, and this proportion is even higher in European adults (86%).”

Dr. Zheng and colleagues acknowledged that study limitations include those that are inherent with observational studies.

Although they could not distinguish between juice, fortified products, or whole foods, the analyses “were adjusted for vitamin supplement use, and suggest that as biomarkers of fruit and vegetable intake these findings endorse the consumption of fruit and vegetables, not that of supplements,” they maintained.

The study by Mr. Hu and colleagues was funded by the National Institutes of Health. The InterAct project was funded by the EU FP6 program. Biomarker measurements for vitamin C and carotenoids were funded by the InterAct project, EPIC-CVD project, MRC Cambridge Initiative, European Commission Framework Program 7, European Research Council, and National Institute for Health Research. Dr. Zheng has reported receiving funding from Westlake University and the EU Horizon 2020 program.

Melanoma in Hispanics: We May Have It All Wrong

Article Type
Changed

To the Editor: 

We read with interest the commentary by Srivastava et al,1 "The Dayanara Effect: Increasing Skin Cancer Awareness in the Hispanic Community," concerning former Miss Universe Dayanara Torres and her diagnosis of metastatic melanoma; however, we believe it misses the mark. A quick Google search shows that Ms. Torres has fair skin and blue eyes. She has lived most of her life in Puerto Rico, the Philippines, and California--places where sun exposure is high and may have contributed to her diagnosis. Factors that have been linked to an increased risk for melanoma are fair skin, red or blonde hair, blue or green eyes, intense intermittent sun exposure and sunburns, a weakened immune system, and a family history of skin cancer.2 Although we do not know her complete medical history, Ms. Torres' skin phenotype and likely chronic UV exposure made her a candidate for skin cancer. Although Srivastava et al1 acknowledged that the Hispanic community encompasses a wide variety of individuals with varying levels of skin pigmentation and sun sensitivity, they overlooked Ms. Torres' risk for skin cancer because of her ethnic background. This form of generalization may negatively affect patient care and safety. By 2060, Hispanics are projected to account for almost 30% of the US population,3 and we must acknowledge the flaws that exist in our overall methodology for assessing skin cancer risk among this population to provide patients with unbiased care.  

In the early 1970s, the United States adopted the ethnonym Hispanic as a way of conglomerating Spanish-speaking individuals from Spain, the Caribbean, and Central and South America.4 The goal was to implement a common identifier that enabled the US Government to study the economic and social development of these groups. Nevertheless, considerable differences exist among distinct Hispanic communities, and variations in skin pigmentation and sun sensitivity are no exception. Although Hispanic countries are an amalgam of diverse races due to colonization, some have stronger European, African, or Amerindian influences, limiting the use of ethnicity during melanoma risk assessment. Another misconception reflected in the commentary by Srivastava et al1 is the belief that the terms white and Hispanic are mutually exclusive. A study examining melanoma rates in the Chilean population supports this claim.5 The genetic composition of the Chilean high socioeconomic strata is 5% Amerindian and 95% white, while the low socioeconomic strata is approximately 40% Amerindian and 60% white. Patients from the low socioeconomic strata had higher rates of acral malignant melanoma, which typically is seen in patients with skin of color. On the other hand, males from the high socioeconomic strata had higher rates of truncal melanoma, which is more common among the white population.5 These results suggest that while both groups are considered Hispanic, it is ancestral origin that contributes to the differential rates and types of malignant melanoma.  

When analyzing data regarding melanoma rates in Hispanics, particularly data collected in the United States, we must question if the results are representative of the entire population. One point worth emphasizing is that melanoma data in the Hispanic community often is flawed. The North American Association of Central Cancer Registries considers Europeans such as Spaniards, as well as citizens of Andorra, the Canary Islands, and the Balearic Islands as Hispanic.6 Additionally, the Florida Cancer Data System uses data such as country of birth, ethnicity, and surname or maiden name recorded by the hospital tumor registry to identify Hispanic patients with melanoma.7 In 2006, Hu et al7 used the Florida Cancer Data System to analyze melanoma data in Miami-Dade County in South Florida, which has the second largest Hispanic community in the United States. One limitation to such data is that ethnicity often is self-reported by patients or assigned by a health care provider. In addition, women whose maiden names are not available may be misclassified through marriage depending on whether their husbands have Spanish or non-Spanish last names.7 Finally, with societal norms evolving, Americans are now more accepting of interracial marriages. In 2017, the Pew Research Center reported that 17% of all newlyweds in the United States were intermarried and 42% of these marriages were between a white individual and a Hispanic individual, comprising the most prevalent form of intermarriage reported.8 In 2015, 27% of newlywed Hispanics were intermarried. This percentage varied depending on whether they were born in the United States or abroad. Although 15% of Hispanic immigrants married a spouse from another race, 39% of Hispanics born in the United States married a non-Hispanic (eg, white, black, Asian, or Native American who is not Hispanic).8 This type of marriage and subsequent offspring might lead to an increase in the white genetic pool. As a result, the risk for melanoma development may be increased or misrepresented. Remaining aware of these changes in the population is crucial, as it exemplifies why the current methodology for gathering and reporting melanoma data is unreliable. 

Labeling Ms. Torres as Hispanic due to her Puerto Rican nationality did not tell us anything about her risk for developing melanoma. To correctly assess the risk for melanoma among Hispanics, it is imperative that we re-evaluate our approach. We agree with He et al9 that our efforts should be dedicated to better understanding the impact of pigmentation, race, genetics, and sunburn on the risk for melanoma. Until we know more about this possible correlation, we should reconsider how we study melanoma using Hispanics as an ethnicity. We may have it all wrong.

Authors' Response 

While Ms. Cruzval-O'Reilly and Dr. Lugo-Somolinos highlight many important points on conducting meaningful research for the Hispanic community, they seem to have misunderstood the overall purpose of our commentary,1 which was to highlight the increased skin cancer awareness that a notable and vocal member of the Hispanic community brought to our academic dermatology clinic, rather than to discuss skin types within the Hispanic community. As the authors mentioned, the term Hispanic is a descriptor of ethnicity rather than race, and Hispanic patients may have varying levels of skin pigmentation and sun sensitivity. While Dayanara Torres may have risk factors for developing melanoma, minimizing her connection with the Hispanic community because of her fair skin and light eyes would be a mistake. It not only isolates members of the Hispanic community that are of skin types I and II, but it also discounts the power of her story and language in raising awareness. We observed an increase in Hispanic patients presenting to our clinic who were concerned about skin cancer after Ms. Torres shared her diagnosis of metastatic melanoma through social media, followed by Spanish language educational videos on melanoma.  

Several studies have described disparities among Hispanic patients diagnosed with melanoma as compared to their non-Hispanic white counterparts, including younger age at diagnosis, later stage of presentation, increased presence of regional involvement, and worse mortality.2-6 Furthermore, a small study of high school students by Ma et al7 showed disparities in skin cancer knowledge, perceived risk, and sun-protective behaviors among Hispanic whites and non-Hispanic whites, which remained significant (P<.05) after controlling for skin pigmentation and sun sensitivity. We agree with the authors that further analysis of skin type, race, genetics, and other risk factors may help refine the research on skin cancer disparities within the Hispanic community. We suspect that disparities may persist even when examining these factors. There have been several studies showing that knowledge-based interventions, especially when delivered in Spanish, improve understanding of skin cancer, personal risk, and self-examinations, and we support Ms. Torres' efforts in utilizing her platform to provide information about melanoma in Spanish.8-12

Authors' Response 

While Ms. Cruzval-O'Reilly and Dr. Lugo-Somolinos highlight many important points on conducting meaningful research for the Hispanic community, they seem to have misunderstood the overall purpose of our commentary,1 which was to highlight the increased skin cancer awareness that a notable and vocal member of the Hispanic community brought to our academic dermatology clinic, rather than to discuss skin types within the Hispanic community. As the authors mentioned, the term Hispanic is a descriptor of ethnicity rather than race, and Hispanic patients may have varying levels of skin pigmentation and sun sensitivity. While Dayanara Torres may have risk factors for developing melanoma, minimizing her connection with the Hispanic community because of her fair skin and light eyes would be a mistake. It not only isolates members of the Hispanic community that are of skin types I and II, but it also discounts the power of her story and language in raising awareness. We observed an increase in Hispanic patients presenting to our clinic who were concerned about skin cancer after Ms. Torres shared her diagnosis of metastatic melanoma through social media, followed by Spanish language educational videos on melanoma.  

Several studies have described disparities among Hispanic patients diagnosed with melanoma as compared to their non-Hispanic white counterparts, including younger age at diagnosis, later stage of presentation, increased presence of regional involvement, and worse mortality.2-6 Furthermore, a small study of high school students by Ma et al7 showed disparities in skin cancer knowledge, perceived risk, and sun-protective behaviors among Hispanic whites and non-Hispanic whites, which remained significant (P<.05) after controlling for skin pigmentation and sun sensitivity. We agree with the authors that further analysis of skin type, race, genetics, and other risk factors may help refine the research on skin cancer disparities within the Hispanic community. We suspect that disparities may persist even when examining these factors. There have been several studies showing that knowledge-based interventions, especially when delivered in Spanish, improve understanding of skin cancer, personal risk, and self-examinations, and we support Ms. Torres' efforts in utilizing her platform to provide information about melanoma in Spanish.8-12

To the Editor: 

We read with interest the commentary by Srivastava et al,1 "The Dayanara Effect: Increasing Skin Cancer Awareness in the Hispanic Community," concerning former Miss Universe Dayanara Torres and her diagnosis of metastatic melanoma; however, we believe it misses the mark. A quick Google search shows that Ms. Torres has fair skin and blue eyes. She has lived most of her life in Puerto Rico, the Philippines, and California--places where sun exposure is high and may have contributed to her diagnosis. Factors that have been linked to an increased risk for melanoma are fair skin, red or blonde hair, blue or green eyes, intense intermittent sun exposure and sunburns, a weakened immune system, and a family history of skin cancer.2 Although we do not know her complete medical history, Ms. Torres' skin phenotype and likely chronic UV exposure made her a candidate for skin cancer. Although Srivastava et al1 acknowledged that the Hispanic community encompasses a wide variety of individuals with varying levels of skin pigmentation and sun sensitivity, they overlooked Ms. Torres' risk for skin cancer because of her ethnic background. This form of generalization may negatively affect patient care and safety. By 2060, Hispanics are projected to account for almost 30% of the US population,3 and we must acknowledge the flaws that exist in our overall methodology for assessing skin cancer risk among this population to provide patients with unbiased care.  

In the early 1970s, the United States adopted the ethnonym Hispanic as a way of conglomerating Spanish-speaking individuals from Spain, the Caribbean, and Central and South America.4 The goal was to implement a common identifier that enabled the US Government to study the economic and social development of these groups. Nevertheless, considerable differences exist among distinct Hispanic communities, and variations in skin pigmentation and sun sensitivity are no exception. Although Hispanic countries are an amalgam of diverse races due to colonization, some have stronger European, African, or Amerindian influences, limiting the use of ethnicity during melanoma risk assessment. Another misconception reflected in the commentary by Srivastava et al1 is the belief that the terms white and Hispanic are mutually exclusive. A study examining melanoma rates in the Chilean population supports this claim.5 The genetic composition of the Chilean high socioeconomic strata is 5% Amerindian and 95% white, while the low socioeconomic strata is approximately 40% Amerindian and 60% white. Patients from the low socioeconomic strata had higher rates of acral malignant melanoma, which typically is seen in patients with skin of color. On the other hand, males from the high socioeconomic strata had higher rates of truncal melanoma, which is more common among the white population.5 These results suggest that while both groups are considered Hispanic, it is ancestral origin that contributes to the differential rates and types of malignant melanoma.  

When analyzing data regarding melanoma rates in Hispanics, particularly data collected in the United States, we must question if the results are representative of the entire population. One point worth emphasizing is that melanoma data in the Hispanic community often is flawed. The North American Association of Central Cancer Registries considers Europeans such as Spaniards, as well as citizens of Andorra, the Canary Islands, and the Balearic Islands as Hispanic.6 Additionally, the Florida Cancer Data System uses data such as country of birth, ethnicity, and surname or maiden name recorded by the hospital tumor registry to identify Hispanic patients with melanoma.7 In 2006, Hu et al7 used the Florida Cancer Data System to analyze melanoma data in Miami-Dade County in South Florida, which has the second largest Hispanic community in the United States. One limitation to such data is that ethnicity often is self-reported by patients or assigned by a health care provider. In addition, women whose maiden names are not available may be misclassified through marriage depending on whether their husbands have Spanish or non-Spanish last names.7 Finally, with societal norms evolving, Americans are now more accepting of interracial marriages. In 2017, the Pew Research Center reported that 17% of all newlyweds in the United States were intermarried and 42% of these marriages were between a white individual and a Hispanic individual, comprising the most prevalent form of intermarriage reported.8 In 2015, 27% of newlywed Hispanics were intermarried. This percentage varied depending on whether they were born in the United States or abroad. Although 15% of Hispanic immigrants married a spouse from another race, 39% of Hispanics born in the United States married a non-Hispanic (eg, white, black, Asian, or Native American who is not Hispanic).8 This type of marriage and subsequent offspring might lead to an increase in the white genetic pool. As a result, the risk for melanoma development may be increased or misrepresented. Remaining aware of these changes in the population is crucial, as it exemplifies why the current methodology for gathering and reporting melanoma data is unreliable. 

Labeling Ms. Torres as Hispanic due to her Puerto Rican nationality did not tell us anything about her risk for developing melanoma. To correctly assess the risk for melanoma among Hispanics, it is imperative that we re-evaluate our approach. We agree with He et al9 that our efforts should be dedicated to better understanding the impact of pigmentation, race, genetics, and sunburn on the risk for melanoma. Until we know more about this possible correlation, we should reconsider how we study melanoma using Hispanics as an ethnicity. We may have it all wrong.

Diagnosing molluscum contagiosum can be tricky

Article Type
Changed

The way James R. Treat, MD, sees it, if there ever were a truism in the field of dermatology, it’s that everyone hates molluscum contagiosum.

Dr. James Treat

“It tortures all of us,” Dr. Treat, a pediatric dermatologist at Children’s Hospital of Philadelphia, said during the virtual Pediatric Dermatology 2020: Best Practices and Innovations Conference. “It’s very distressing to parents, but often more distressing to parents than to kids.”

A viral disorder of the skin and mucous membranes characterized by discrete single or multiple, flesh-colored papules, molluscum contagiosum (MC) lesions often appear on the face, neck, armpits, arms, and tops of the hands in children. The abdomen and inner thighs can also be affected. “When you look at inflamed molluscum it can be very difficult to recognize because it looks like a more complicated infection,” said Dr. Treat, who is also associate professor of clinical pediatrics and dermatology, at the University of Pennsylvania, Philadelphia.

An epidemiologic review of 302 MC cases found that 80% of patients were aged younger than 8 years, 63% had more than 15 lesions, and 24% had concomitant atopic dermatitis (J Am Acad Dermatol. 2006; 2006;54[1]:47-54). “Children with atopic dermatitis often have their molluscum last longer,” he said. “The average time course for molluscum is 18 months, but it can certainly be longer than that. So if you say, ‘it’s probably going to go away in a few months,’ that’s probably not going to happen.”

The telltale MC lesion is glossy and contains a white core in the center that can be revealed by shining an otoscope sideways on the lesion. “Umbilication doesn’t always occur, but if the center part looks white, that will help with diagnosis,” Dr. Treat said. “If they’re inflamed and they’re red and you’re worried that there’s a bacterial infection, do a culture, pop the lesion open, and get some of the pus out. If you’re concerned, start them on antibiotics. It’s always worse to miss an infection than to overtreat molluscum. But once you’ve done it a few times and you realize that the cultures are coming back negative, then you’ll probably have your threshold a little higher.”



The most useful clinical sign of MC is the so-called “BOTE” (beginning of the end) sign, which is characterized by erythema and swelling of MC skin lesions. “When the parents come to us in pediatric dermatology, often it’s because their kids have had molluscum for a while,” he said. “It spreads and becomes inflamed and the parents ask, ‘Is it infected?’ The answer is, yes, it’s an infection, but it’s not infected with what you think it is [which is Staphylococcus or Streptococcus], it’s the virus being recognized by the body. When the virus is recognized by the body, it creates a huge inflammatory reaction. That’s usually the time at which the body has had enough of the virus, and it eradicates the rest of it. It means the inflammatory response is finding the molluscum and it’s going to take care of it.”

MC brings its own eczematous response, which can complicate efforts to confirm the diagnosis. Dr. Treat spoke of a young patient he recently saw who had an eczematous reaction on the inner parts of the arms and the upper flank – with no such clinical history. “It kind of came out of the blue,” he said. “You think about contact allergies and other types of dermatitis, but molluscum brings its own eczema. Often what the parents recognize is the eczematous eruption and not the little dots of molluscum. So if you see someone with a new eruption in typical molluscum areas – the flank and your thighs and the back of the legs – and they’ve never had eczema in the past, or they’ve only had mild eczema, think about eczema as a response to molluscum.”

MC can also result in a Gianotti-Crosti syndrome-like reactions (Arch Dermatol. 2012;148[11]:1257-64). “These are angry, inflamed red papules on the knees and on the elbows and on the buttocks and on the cheeks,” Dr. Treat said. “It typically spares the trunk, and they look like molluscum.”

He went on to note that MC can present as cysts, and that MC in the gluteal cleft is a mimicker of condyloma. MC can also cause conjunctivitis, which is increased in HIV patients and in those with atopic dermatitis. “These are patients who should probably see an ophthalmologist” to make no damage has occurred, Dr. Treat said.

He closed his remarks by noting that rarely, MC can be the presenting sign of an immunodeficiency. “The immune system dysregulation that shows up this way is called a DOCK8 mutation, which have eczema and widespread viral disease including warts and molluscum,” Dr. Treat said.

He reported having no financial disclosures.

An epidemiologic review of 302 MC cases found that 80% of patients were aged younger than 8 years, 63% had more than 15 lesions, and 24% had concomitant atopic dermatitis (J Am Acad Dermatol. 2006; 2006;54[1]:47-54). “Children with atopic dermatitis often have their molluscum last longer,” he said. “The average time course for molluscum is 18 months, but it can certainly be longer than that. So if you say, ‘it’s probably going to go away in a few months,’ that’s probably not going to happen.”

The telltale MC lesion is glossy and contains a white core in the center that can be revealed by shining an otoscope sideways on the lesion. “Umbilication doesn’t always occur, but if the center part looks white, that will help with diagnosis,” Dr. Treat said. “If they’re inflamed and they’re red and you’re worried that there’s a bacterial infection, do a culture, pop the lesion open, and get some of the pus out. If you’re concerned, start them on antibiotics. It’s always worse to miss an infection than to overtreat molluscum. But once you’ve done it a few times and you realize that the cultures are coming back negative, then you’ll probably have your threshold a little higher.”



The most useful clinical sign of MC is the so-called “BOTE” (beginning of the end) sign, which is characterized by erythema and swelling of MC skin lesions. “When the parents come to us in pediatric dermatology, often it’s because their kids have had molluscum for a while,” he said. “It spreads and becomes inflamed and the parents ask, ‘Is it infected?’ The answer is, yes, it’s an infection, but it’s not infected with what you think it is [which is Staphylococcus or Streptococcus], it’s the virus being recognized by the body. When the virus is recognized by the body, it creates a huge inflammatory reaction. That’s usually the time at which the body has had enough of the virus, and it eradicates the rest of it. It means the inflammatory response is finding the molluscum and it’s going to take care of it.”

MC brings its own eczematous response, which can complicate efforts to confirm the diagnosis. Dr. Treat spoke of a young patient he recently saw who had an eczematous reaction on the inner parts of the arms and the upper flank – with no such clinical history. “It kind of came out of the blue,” he said. “You think about contact allergies and other types of dermatitis, but molluscum brings its own eczema. Often what the parents recognize is the eczematous eruption and not the little dots of molluscum. So if you see someone with a new eruption in typical molluscum areas – the flank and your thighs and the back of the legs – and they’ve never had eczema in the past, or they’ve only had mild eczema, think about eczema as a response to molluscum.”

MC can also result in a Gianotti-Crosti syndrome-like reactions (Arch Dermatol. 2012;148[11]:1257-64). “These are angry, inflamed red papules on the knees and on the elbows and on the buttocks and on the cheeks,” Dr. Treat said. “It typically spares the trunk, and they look like molluscum.”

He went on to note that MC can present as cysts, and that MC in the gluteal cleft is a mimicker of condyloma. MC can also cause conjunctivitis, which is increased in HIV patients and in those with atopic dermatitis. “These are patients who should probably see an ophthalmologist” to make no damage has occurred, Dr. Treat said.

He closed his remarks by noting that rarely, MC can be the presenting sign of an immunodeficiency. “The immune system dysregulation that shows up this way is called a DOCK8 mutation, which have eczema and widespread viral disease including warts and molluscum,” Dr. Treat said.

He reported having no financial disclosures.
