Atopy was not related to development of eczema or asthma in children under age 13 years, according to Ann-Marie Malby Schoos, Ph.D., and her associates at the University of Copenhagen.

Allergic sensitization increased with age in the 399 children tested, rising from 12% at 6 months to 54% at 13 years. The incidence of asthma was highest at age 4 years at 16%, but decreased afterward, falling to 12% at 13 years. The incidence of eczema peaked at 39% in children aged 1.5 years old, but decreased steadily to only 12% in 13-year-olds.

Asthma and allergic sensitization were related only in late childhood, with an odds ratio of 4.49 in 13-year-olds. This pattern was seen throughout allergic sensitization subgroups. There were strong associations between eczema and allergic sensitization at 6 months (OR, 6.02), 1.5 years (OR, 2.06), and 6 years (OR, 2.77), but no association at 13 years. The proportion of children with allergic sensitization who did not have asthma or eczema also increased with age.

“The tradition of using atopy as a particular endotype of asthma and eczema seems unfounded because it depends on the method of testing for sensitization, type of allergens, and age of the patient. This questions the relevance of the terms atopic asthma and atopic eczema as true endotypes,” the investigators concluded.

LOS ANGELES – Children who pass oral food challenges to baked egg and milk with wheat flour are at risk for reacting to baked goods made with nonwheat flours, according to a review of more than 200 pediatric food challenges at National Jewish Health in Denver.

The children were already known to be sensitive to egg and milk, and some were being challenged to see if exposure therapy was helping. Unbeknown to the pediatric food allergy team, a kitchen worker at National Jewish had started making muffins with rice flour, thinking it would be safer.

During the month of muffins with rice flour, the failure rate for baked egg challenge muffins rose from 28% (33/120) to 58% (11/19) with rice flour. Failure to baked milk muffins rose from 14% (9/66) to 36% (5/14) (J Allergy Clin Immunol. 2016 Feb. doi: 10.1016/j.jaci.2015.12.579).

Adjusting for age, gender, and atopic dermatitis, children were more than five times more likely to fail baked eggs without wheat (odds ratio, 5.4; P = .002), and more than four times more likely to fail baked milk (OR, 4.06; P = .05).

Given that the phenomenon hasn’t been reported before, “This was very surprising to us,” said study investigator Dr. Bruce Lanser, director of the pediatric food allergy program at National Jewish. “You have to warn parents that if children pass a baked challenge with wheat, they have to continue to eat their baked milk and egg with wheat. Gluten-free products are not going to have the same effect.

“If somebody is avoiding wheat because it causes a bit of redness and itchiness, you have to clear that wheat allergy” before moving to baked egg and milk, Dr. Lanser added.

There’s also concern that “kids will go home after passing a wheat muffin challenge, eat something that’s gluten-free, and have a reaction,” he noted. Wheat-free baked goods might also not build tolerance as well, although that’s not clear from the study, Dr. Lanser said at the annual meeting of the American Academy of Allergy, Asthma, and Immunology.

Wheat seems to have something unique that alters the allergic properties of egg and milk proteins to help children outgrow their sensitivities. “Rice doesn’t have the same effect,” he observed, and it’s not known if any other grains do. Dr. Lanser said he is interested in looking into rye, barley, oats, and other alternatives.

The mean age of the children in the study was 6 years, and most children had multiple food allergies. Sensitization was confirmed by skin tests and specific IgE.

Meanwhile, there’s a new rule in the National Jewish kitchen: Unless a child has true celiac disease, “always make [challenge] muffins with wheat,” Dr. Lanser said.

There was no industry funding for the work, and the investigators had no disclosures.

Neonates with the highest transepidermal water loss at birth, likely mediated through an impaired epidermal barrier, show significantly elevated chymotrypsinlike protease activity and reduced levels of filaggrin-derived natural moisturizing factors, which may predispose them to the development of atopic dermatitis, according to a report published online in the British Journal of Dermatology.

John Chittock of the University of Sheffield, England, and his colleagues assessed the biophysical, biologic, and functional properties of the developing neonatal stratum corneum (SC) from birth to 4 weeks of age in 115 healthy, full-term (at least 37 weeks’ gestation) neonates from the OBSERVE (Oil in Baby Skincare) randomized study birth cohort recruited at Saint Mary’s Hospital, Central Manchester NHS Foundation Trust, between September 2013 and June 2014.

For comparative purposes, an unrelated cohort of 20 adults with healthy skin was recruited from the local community between January and April 2015 (Br J Dermatol. 2016 Mar 19. doi: 10.1111/bjd.14568).

The researchers found that the biophysical properties of the neonatal SC are transitional from birth. For example, overall transepidermal water loss (TEWL) increased significantly during the first 4 weeks of infant life. Compared with adult skin, the newborn infant SC was found to be drier and more alkaline. In addition, levels of superficial chymotrypsinlike protease activity at birth did not differ between newborns and adults, while levels of filaggrin-derived natural moisturizing factors (NMF) were significantly lower at birth than in adulthood.

The increased chymotrypsinlike protease activity and NMF at 4 weeks of age exceeded levels found in healthy adults, rather than reaching their mature state. Compared with adult skin, the skin of infants is functionally immature, with undeveloped mechanisms of desquamation and differentiation, the investigators noted.

Further analysis revealed a correlation between TEWL and both superficial chymotrypsinlike protease activity and filaggrin-derived NMF at birth.

To explore that link, the researchers stratified the neonatal cohort according to TEWL percentile. The neonates in the 76th-100th percentile, the highest TEWL at birth, showed significantly elevated chymotrypsinlike protease activity and reduced levels of filaggrin-derived NMF, compared with neonates in lower percentiles. Therefore, those neonates are at highest risk for developing atopic dermatitis, the study authors said.

The findings indicate a need for infant skin care regimens that protect and support normal barrier development from birth, the researchers noted. They also suggested that clinical strategies targeting the early mechanisms of barrier breakdown could act as preventive measures in neonates at increased risk of developing atopic dermatitis.

The research was funded jointly by the University of Sheffield and a doctoral research fellowship supported by the National Institute for Health Research. The authors declared no conflicts of interest.

New findings confirm that although it is rare, postvaccination anaphylaxis can still occur with certain vaccines.

Dr. Michael M. McNeil of the Centers for Disease Control and Prevention, Atlanta, and his associates identified 17,606,500 vaccination visits from Jan. 1, 2009, through Dec. 31, 2011, at which 25,173,965 vaccine doses were administered. The researchers identified 76 cases of chart-confirmed anaphylaxis; 33 anaphylaxis cases were associated with vaccination, and 43 were attributed to other causes.

Inactivated trivalent influenza vaccine (TIV) was the major contributor to vaccine-triggered anaphylaxis cases in the population, although the rate (1.35 cases per 1 million vaccine doses of TIV given alone) was similar to the rate for all vaccines. The postvaccination anaphylaxis case rate not involving TIV was 1.32 per million vaccine doses.

The study factored in race, age, gender, symptoms, and history of the patients. There were no deaths, and only 1 patient (3%) was hospitalized. A total of 28 of the 33 vaccine-triggered anaphylaxis cases involved patients with a history of atopy.

“Although anaphylaxis after immunization is rare, its immediate onset (usually within minutes) and life-threatening nature require that all personnel and facilities providing vaccinations have procedures in place for anaphylaxis management,” the investigators noted. “Additional provider education concerning current recommendations for treatment and follow-up appears to be warranted.”

A third straight week of reduced influenza-like illness (ILI) left the U.S. with no states at the highest level of ILI activity for the first time since early February, according to the Centers for Disease Control and Prevention.

The states with the highest activity for the week ending April 2, 2016, were New Jersey and New Mexico, and both were at level 8 on the CDC’s 1-10 scale, putting them on the low end of the “high” range. States in the “moderate” range were Georgia and North Carolina at level 7 and Alabama, Alaska, Arkansas, Missouri, and Virginia at level 6, according to a report from the CDC’s Influenza-like Illness Surveillance Network (ILINet).

The proportion of outpatient visits for ILI was 2.4% for the week, down from 2.9% the week before but still above the national baseline of 2.1%, the CDC said. The CDC also reported a cumulative rate of 24.4 laboratory-confirmed influenza-associated hospitalizations per 100,000 population for the 2015-16 flu season.

There were seven flu-related pediatric deaths reported – all of them occurring during earlier weeks. So far, 40 flu-related pediatric deaths have been reported during the 2015-2016 season, with California having the highest number (9). The CDC said 7.4% of all deaths reported through the 122 Cities Mortality Reporting System were due to pneumonia and influenza. This percentage was above the epidemic threshold of 7.1% for week 13 of the flu season.

WAIKOLOA, HAWAII – The list of nonatopic comorbid conditions associated with atopic dermatitis is rapidly expanding.

Just in the past year, published studies have linked pediatric atopic dermatitis to increased risks of obesity, high blood pressure, headaches, anemia, and speech disorders. Meanwhile, adult atopic dermatitis was reported to be associated with increased rates of fracture and cardiovascular disease. And in the dermatologic arena, a link between atopic dermatitis, vitiligo, and alopecia areata was identified, Dr. Lawrence F. Eichenfield noted at the Hawaii Dermatology Seminar provided by the Global Academy for Medical Education/Skin Disease Education Foundation.

Actually, these reported associations published in 2015-2016 might best be termed “emerging comorbidities,” as they are first reports and thus need confirmation, said Dr. Eichenfield, professor of dermatology and pediatrics at the University of California, San Diego, and chief of pediatric and adolescent dermatology at Rady Children’s Hospital San Diego.

Much of this work on emerging comorbidities has been done by dermatologist Dr. Jonathan I. Silverberg of Northwestern University, Chicago, and various coinvestigators. They have been prolific.

For example, in a multivariate logistic regression analysis of 207,007 children and adolescents included in the cross-sectional 1997-2013 U.S. National Health Interview Survey, Dr. Silverberg and coinvestigators found that eczema was independently associated with a 1.83-fold increased odds of anemia. They bolstered this observation with an analysis of more than 30,000 children and adolescents in the 1992-2012 National Health and Nutrition Examination Survey (NHANES) in which they found that current eczema was associated with a 1.93-fold increased odds of anemia, particularly microcytic anemia. The underlying mechanism is unknown; however, the investigators noted that chronic inflammation and systemic immunosuppressant drugs have been shown to be associated with anemia (JAMA Pediatr. 2016;170[1]:29-34).

Dr. Silverberg also found in a multivariate logistic regression analysis of data on more than 400,000 pediatric participants in the National Survey of Children’s Health and the National Health Interview Survey that mild and severe eczema were independently associated with 1.79-fold and 2.72-fold, respectively, increased odds of headaches (J Allergy Clin Immunol. 2016 Feb;137[2]:492-9).

Using these same two data sources, with multivariate analysis adjusted for potential confounders, the investigators found that eczema was associated with a 1.81-fold increased risk of speech disorder (J Pediatr. 2016 Jan;168:185-92).

In a case-control study involving 132 children and adolescents with current moderate to severe atopic dermatitis and 143 healthy controls, Dr. Silverberg and coinvestigators found in a logistic regression analysis that atopic dermatitis was independently associated with a doubled risk of having a systolic blood pressure in the 90th percentile or higher – as well as 3.92-fold increased odds of central obesity, as defined by a waist circumference in the 85th percentile or higher (JAMA Dermatol. 2015 Feb;151[2]:144-52).

In a systematic review and meta-analysis of 16 published vitiligo studies and 17 published studies of alopecia areata, Dr. Silverberg and medical student Girish C. Mohan found that patients with vitiligo or alopecia areata were respectively 7.8 and 2.6 times more likely to have atopic dermatitis than controls without those disorders (JAMA Dermatol. 2015 May;151[5]:522-8).

In a logistic regression analysis of data on 34,500 adults with a history of eczema within the prior year who participated in the 2012 National Health Interview Survey, Drs. Nitin Garg and Dr. Silverberg concluded that the results suggested that adult atopic dermatitis is a previously unrecognized risk factor for fracture and other bone or joint injuries causing limitation. Adults with atopic dermatitis were at a 1.67-fold increased risk for such injuries in an analysis controlling for sociodemographics, other forms of atopic disease, and psychiatric and behavioral disorders (JAMA Dermatol. 2015 Jan;151[1]:33-41).

In another large cross-sectional study, Dr. Silverberg found that adults with atopic dermatitis had significantly higher odds of a history of acute MI, coronary artery disease, heart failure, and stroke (Allergy. 2015 Oct;70[10]:1300-8).

Dr. Eichenfield said that while he would like to see these hot-off-the-presses 2015-2016 findings on nonatopic comorbidities backed up by confirmatory studies in other populations, the evidence is stronger for an association between pediatric atopic dermatitis and several mental health disorders. The initial reports came mainly from Europe, but were then supported by a large study by Dr. Eric L. Simpson and coinvestigators at Oregon Health and Science University, Portland.

In their analysis of data on nearly 93,000 noninstitutionalized children and adolescents included in the 2007 National Survey of Children’s Health, the investigators found after controlling for potential confounders that atopic dermatitis was associated with a 1.87-fold increased risk of having attention-deficit/hyperactivity disorder, a 3-fold increased risk of diagnosed autism, an adjusted 1.81-fold increase in depression, and 1.87-fold increased odds of conduct disorder. The Oregon group found a clear dose-dependent relationship between the reported severity of the skin disease and the likelihood of those mental health disorders (J Allergy Clin Immunol. 2013 Feb;131[2]:428-33).

The hope is that emerging strategies to prevent atopic dermatitis or aggressively treat it early on will reduce the risk of many of these comorbid conditions, Dr. Eichenfield said.

WAIKOLOA, HAWAII – The list of nonatopic comorbid conditions associated with atopic dermatitis is rapidly expanding.

Just in the past year, published studies have linked pediatric atopic dermatitis to increased risks of obesity, high blood pressure, headaches, anemia, and speech disorders. Meanwhile, adult atopic dermatitis was reported to be associated with increased rates of fracture and cardiovascular disease. And in the dermatologic arena, a link between atopic dermatitis, vitiligo, and alopecia areata was identified, Dr. Lawrence F. Eichenfield noted at the Hawaii Dermatology Seminar provided by the Global Academy for Medical Education/Skin Disease Education Foundation.

Actually, these reported associations published in 2015-2016 might best be termed “emerging comorbidities,” as they are first reports and thus need confirmation, said Dr. Eichenfield, professor of dermatology and pediatrics at the University of California, San Diego, and chief of pediatric and adolescent dermatology at Rady Children’s Hospital San Diego.

Much of this work on emerging comorbidities has been done by dermatologist Dr. Jonathan I. Silverberg of Northwestern University, Chicago, and various coinvestigators. They have been prolific.

For example, in a multivariate logistic regression analysis of 207,007 children and adolescents included in the cross-sectional 1997-2013 U.S. National Health Interview Survey, Dr. Silverberg and coinvestigators found that eczema was independently associated with a 1.83-fold increased odds of anemia. They bolstered this observation with an analysis of more than 30,000 children and adolescents in the 1992-2012 National Health and Nutrition Examination Survey (NHANES) in which they found that current eczema was associated with a 1.93-fold increased odds of anemia, particularly microcytic anemia. The underlying mechanism is unknown; however, the investigators noted that chronic inflammation and systemic immunosuppressant drugs have been shown to be associated with anemia (JAMA Pediatr. 2016;170[1]:29-34).

Dr. Silverberg also found in a multivariate logistic regression analysis of data on more than 400,000 pediatric participants in the National Survey of Children’s Health and the National Health Interview Survey that mild and severe eczema were independently associated with 1.79-fold and 2.72-fold, respectively, increased odds of headaches (J Allergy Clin Immunol. 2016 Feb;137[2]:492-9).
