What are the main findings? Response: Self management plans are recommend for patients with asthma but previous studies have shown that doubling the dose of inhaled steroids when asthma starts deteriorating is ineffective at preventing the development of an exacerbation. This study shows that quadrupling the dose is effective and in a real-life setting can reduce severe exacerbations by about 20%

What are the main findings? Response: I was motivated to study the maternal asthma-infant microbiome link by the well-established fact that maternal asthma affects infant birth weight in a sex-specific manner. Based on data from AllerGen’s CHILD birth cohort, Caucasian baby boys born to pregnant moms with asthma—putting them at the highest risk for developing asthma in early childhood—were one-third as likely to have high levels of the microbe, Lactobacillus, in their gut microbiome at 3-4 months after birth.

What are the main findings? Response: The Canadian Healthy Infant Longitudinal Development (CHILD) Study was initiated in 2008, funded by AllerGen NCA and CIHR, to determine root causes of allergy and asthma. We recruited 3623 pregnant mothers in 4 centers across Canada and are following 3495 eligible children from pregnancy to age 5 years. In this paper we describe some of the findings in early childhood, namely that children who develop skin conditions generally called eczema or atopic dermatitis, who are also sensitized to food allergens (milk, egg, peanut) at 1 year are at high risk of developing subsequent asthma, whereas those with these skin conditions but not sensitized are not at such risk.

What are the main findings? Response: We studied asthma prescription drug use in Ontario children aged 2 to 18 years with physician diagnosed asthma between 2003 and 2014. We found that:
  1. Currently in Ontario, nearly 50% of children with asthma did not fill a prescription for an inhaled corticosteroid during the study period, despite these medications being considered the gold-standard for asthma management.
  2. Our findings did not show clinically important association between inhaled corticosteroids and fracture among children with asthma.
  3. However, systemic corticosteroids (oral or injection) are associated with higher fracture risk in children with asthma (17% higher risk).

Response: Lungprint is an interactive digital tool that creates a dynamic visual representation of a person’s lungs based on their unique experiences with asthma. It is meant to provide people with asthma a better understanding of the role of asthma in their life and motivate them to have a more personalized conversation with their healthcare provider about the severity of their symptoms, a more individualized treatment plan and a blood test that measures eosinophil levels. Each person’s Lungprint, which is generated as they respond to a digital questionnaire about their experience with asthma, will help reveal information about their individual experience with asthma.

What are the main findings? Response: This study proves that asthmatic children already have a hyperactive calcium channel that’s extremely sensitive to environmental triggers. If these children contract a virus, such as RSV, the hyperactive channel causes more severe symptoms that may require care in a hospital setting. When a child developed asthma or bronchitis in the past, doctors thought these conditions could only be triggered by environmental allergens. There was no explanation why two out of three children ages five and under who wheeze and cough – and still test negative for allergies. We needed to explore the mechanisms of the calcium molecule and the epithelial cells, which seem to trigger these symptoms without an allergic reaction. If the molecule’s behavior is producing the cough, we just need to figure out how to control the molecule to properly deactivate the cough mechanism in the asthmatic child

Response: Asthma affects more than 300 million people worldwide and is estimated to cause almost 400,000 deaths annually. Asthma deaths arise primarily during episodes of acute worsening of symptoms, known as attacks or ‘exacerbations’, which are commonly triggered by viral upper respiratory infections. Vitamin D is thought to protect against such attacks by boosting immune responses to respiratory viruses and dampening down harmful airway inflammation. Several clinical trials have tested whether vitamin D supplementation might protect against asthma attacks, but individually their results are inconclusive. In the current study, we pooled raw data from 955 asthma patients who took part in 7 separate trials, which allowed us to answer two questions: 1, Does vitamin D protects against asthma attacks overall, when data from all trials are pooled? 2, Do people who have lower vitamin D levels to start with particularly benefit from supplementation?

What are the main findings? Response: Adults with asthma are at increased risk for pneumococcal infection. Adults with asthma who get pneumococcal pneumonia are at risk for additional complications including asthma exacerbation and invasive pneumococcal disease. Our results indicated that adults with work-related asthma were more likely to have received a pneumococcal vaccine than adults with non-work-related asthma—54 percent compared to 35 percent respectively; however, pneumococcal vaccination coverage among all adults with asthma, work-related or not, who have ever been employed in this study falls short of achieving the coverage public health experts recommend. Among adults with work-related asthma, pneumococcal vaccine coverage was lowest among Hispanics (36 percent), those without health insurance (39 percent), and adults aged 18 to 44 years (42 percent).

What are the main findings? Response: Observational studies have limitations in their ability to examine disparities in asthma, as these studies have relied on self-reported measures of medication use, asthma diagnosis, severity, outcomes, and access to care. Using data collected from a randomized controlled trial, we found that subjects with lower income had a significantly higher number of asthma treatment failures and asthma exacerbations, independent of race, BMI, education, perceived stress, baseline lung function, hospitalizations, inhaled corticosteroid adherence, inhaled corticosteroid dose, environmental allergen sensitization, and second-hand smoke exposure.

What are the main findings? Response: Some previous epidemiological studies have suggested that low vitamin D levels are associated with increased rates of asthma, atopic dermatitis—an itchy inflammation of the skin—and elevated levels of IgE, an immune molecule linked to atopic disease (allergies). In our study, we looked at genetic and health data on more than 100,000 individuals from previous large studies to determine whether genetic alterations that are associated with vitamin D levels predispose people to the aforementioned conditions. We found no statistically significant difference between rates of asthma (including childhood-onset asthma), atopic dermatitis, or IgE levels in people with and without any of the four genetic changes associated with lower levels of 25-hydroxyvitamin D, the form of vitamin D routinely measured in the blood.

Pound MD The Ottawa Children’s Treatment Centre Dr. Catherine Pound[/caption] Catherine M. Pound MD The Ottawa Children’s Treatment Centre MedicalResearch.com: What is the background for this study? Response: Asthma is the most common chronic disease of childhood and contributes to a large portion of Canadian hospital pediatric admissions.  Once patients are admitted to hospitals, they receive salbutamol, a medication used for acute asthma exacerbations, at a pre-determined frequency.  In most hospitals, physicians are the ones to decide of the frequency of administration of the salbutamol, and they decide when to wean patients off it. However, children whose salbutamol treatment administration can be decreased are usually considered stable, and often do not require immediate medical attention, which may results in delays in reassessments as well as administration of unneeded salbutamol treatments, particularly if physicians are busy looking after other sicker patients.  Additionally, physicians’ assessments of children with asthma and their decisions to wean salbutamol frequency are not standardized, and vary among physicians. Therefore, in order to improve efficiency and standardize patient assessments, we developed a clinical pathway allowing nurses to wean salbutamol for children hospitalized with asthma based on a validated asthma scoring system.

MedicalResearch.com Interview with: Rauno Joks, MD Associate Professor of Clinical Medicine Chief, Division of Allergy & Immunology Program Director, Allergy &Immunology Fellowship SUNY Downstate Medical Center MedicalResearch.com: What is the background for this study? What are the main findings? Response: There are circadian and circannular patterns to many diseases, including allergy and asthma. Humans spend roughly one-third of their lifetimes asleep. Your immune system never sleeps, but shifts its activity when you sleep. It is known that asthma disease activity can be worse at night - the reasons for this are complex, and may involve changes in allergic responses. We found, in a preliminary study of both adults with and without asthma, that longer duration of nighttime sleep was associated with lower levels of exhaled nitric oxide, a biomarker which is elevated in exhaled breath of those with allergic asthma. This may carry over into the afternoon as well, but the sample size was too small to fully conclude that.

Sullivan, Ph.D. Professor Regis University School of Pharmacy Denver, CO 80221 MedicalResearch.com: What is the background for this study? Response: Asthma is one of the most common chronic disorders among children. It affects 7.1 million children in the U.S. Of these, 4.1 million children suffered an asthma attack in 2011. An asthma attack is an acute period of extreme difficulty breathing. It can be life threatening and is always very frightening for children. Because asthma can be dangerous and frightening, it ends up costing a lot because patients need to go the doctor, hospital or take medications to try to control it. Asthma also has a negative effect on the patient’s health and outlook about their health – both mentally and physically. Previous studies have focused on adults with asthma and have found that it is very expensive – it costs $18 billion in the U.S. to manage adults with asthma. Those studies also showed that adults with asthma have lower quality of life. However, there is not a lot of good evidence on the burden of asthma in children. This study was designed to quantify the cost and mental and physical health of children with asthma in the U.S.

Response: Asthma prevalence varies across and within countries, and markedly increased rates of asthma have been observed in recent decades. Recent time-trends may be attributed to increased urbanization and dissemination of a Western lifestyle. In the US, asthma disproportionally affects African-Americans and Hispanics/Latinos living in urban areas. Among Hispanics/Latinos, asthma prevalence varies from 5.7 % for Mexicans/Mexican-Americans to 16.5% for Puerto Ricans. Besides national background, US nativity, longer duration of US residence, and having one or two parents born in the US have been previously reported as acculturation-related risk factors for asthma in foreign born children. Asthma prevalence was also higher in foreign-born Latinos who relocated to the US as children.

COPSAC, Herlev and Gentofte Hospital University of Copenhagen Copenhagen, Denmark MedicalResearch.com: What is the background for this study? Response: Asthma and lower respiratory infections are leading causes of morbidity and mortality in pediatric populations. Thus, having low cost, effective, safe options for prevention could have important implications for both clinical practice and public health. The increased use of vegetable oils in cooking and of grain in the feeding of livestock has resulted in an increase in the intake of n−6 polyunsaturated fatty acids and a decrease in the intake of n−3 polyunsaturated fatty acids, especially the long-chain poly-unsaturated fatty acids (LCPUFAs) — eicosapentaenoic acid (20:5n–3, EPA) and docosahexaenoic acid (22:6n–3, DHA) — found in cold-water fish. N3-LCPUFAs are known to have immune-modulatory effects, and observational studies have suggested an association between a diet that is deficient in n−3 LCPUFA during pregnancy and an increased risk of asthma and wheezing disorders in offspring. Only a few randomized, controlled trials of n−3 LCPUFA supplementation during pregnancy have been performed and these have generally been underpowered and produced ambiguous results. Therefore, we conducted a double-blind, randomized, controlled trial of n−3 LCPUFA supplementation during the third trimester of pregnancy in a total of 736 Danish women to assess the effect on the risk of persistent wheeze and asthma in offspring. The clinical follow-up rate among children was 96% (N=664) by the end of the 3 years double-blind period and 93% (N=647) after an additional follow-up to age 5 years.

Response: Asthma is the most prevalent chronic disease of childhood. Epidemiological evidence suggests that the disease often begins during the pre-school years even when chronic symptoms appear much later in life. However, firm criteria to pinpoint how early a child’s trajectory to asthma truly begins are currently lacking. The mechanisms underlying asthma inception also remain largely unknown. Although epigenetic mechanisms likely contribute to asthma pathogenesis, little is known about their role in asthma inception.

MedicalResearch.com Interview with: Zhen LI, MD, MPH, PhD Candidate INSERM UMR-S 1168 (ex-Equipe 5 du CESP) (VIMA : Aging and chronic diseases. Epidemiological and public health approaches.), Hôpital Paul Brousse France MedicalResearch.com: What is the background for this study? What are the main findings? Response: -Cured meat, which is rich in nitrite, has been known as a probable carcinogen. However, although some studies have suggested a potential deleterious role of cured meat intake in lung health, its role in asthma remained unknown. This study was conducted using data from the French Epidemiological study on the Genetics and Environment of Asthma (EGEA). Using data from 971 participants with seven years' follow-up, we found that participants who ate frequently cured meat, including ham, sausages, and dried sausages, had a high likelihood of having worsening asthma symptoms. The highest likelihood (76% more) was observed among participants who ate cured meats four or more servings per week, compared with those who ate less than one serving per week. Moreover, as previous studies suggested that obesity is linked to worsening asthma, we used a newly developed method to estimate if this effect was mediated by Body Mass Index (BMI), and we found that overweight/obesity only partly explained the association (14%).

What are the main findings? Response: In 2012, Missouri House Bill 1188 was passed, which allowed trained employees in Missouri schools to administer asthma related rescue medications at their discretion to students experiencing an asthma exacerbation, even if the individual student did not have their own supply of the medication. The Asthma and Allergy Foundation of America St. Louis Chapter (AAFA-STL) was instrumental in facilitating passage of this bill and also created the RESCUE (Resources for Every School Confronting Unexpected Emergencies) program, which provides equipment and access to free medications to treat acute asthma symptoms, mainly supporting schools with lower income populations. AAFA-STL tracked how often RESCUE supplies were used and found that equipment was used 1357 individual times in 2013-2014 school year, with students going back to class 86.07%, sent home 10.83%, and sent to emergency department (ED) only 1.33% of the time. In the 2014-2015, they found similar results with equipment used 1720 individual times, with students going back to class 84.48%, sent home 10.81%, and sent to ED 3.14% of the time.

It is particularly important for children with asthma, who are at high risk of hospitalization or severe illness if they contract influenza infection. The rates of influenza vaccination in children with asthma have not previously been well studied, but Healthy People 2020 has set a target goal to vaccinate 70% of all children for influenza. We found that rates of vaccination in our large primary care population was much lower than the target rate, with less than 50% of all children receiving the vaccine each year over a 5 year period; however rates were higher in children with asthma, albeit still only at 55%.

Response: Obesity is a risk factor for new-onset asthma, but the association is incompletely understood. Our aim was, therefore, to investigate the association between body mass index (BMI) BMI in childhood and asthma admissions in early adulthood (until age 45 years). We used data on BMI measured annually (age 7-13 years) in 321,830 children enrolled in the Copenhagen School Health Records Registry. During the 36-years of follow-up, a total of 2,059 first-time ever hospital admissions for asthma were observed.

Response: For almost thirty years there has been evidence that we are all born with a certain predisposition to what are called non communicable diseases (NCD) such as high blood pressure, type II diabetes and heart disease. The evidence comes from studies which have linked reduced birth weight with increased risk for these NCDs in later life. The question which arises, and which has been more difficult to answer, is “when during pregnancy is the predisposition to for NCDs first seen?” This is important to any attempt to reduce the unborn baby’s risk for NCD. We and other researchers have used fetal ultrasound data to link size before birth to non communicable diseases outcomes. In childhood, NCDs include asthma.

Ducharme, MD, FRCPC Professor, Departments of Paediatrics and Social and Preventive Medicine University of Montreal Associate Director of Clinical Research and Knowledge Transfer, Research Centre, CHU Ste-Justine MedicalResearch.com: What is the background for this study? What are the main findings? Response: The management of asthma attacks in preschoolers has been the subject of much recent debate. The results of a study published in 2009 had shaken the pediatric world. The study reported that preschool children with viral-triggered flare-ups did not respond to standard treatment and, suggesting that this was due to their young age. Such finding was particularly worrisome as the majority of asthma-related emergency room visits and hospitalizations involve preschool children. We conducted this large cohort study in which children aged 1 to 17 years with a moderate or severe asthma attack were treated using the established evidence-based therapy adjusted to the severity of exacerbation assessed by the Pediatric Respiratory Assessment Measure (PRAM), administered rapidly. We explored the determinants of the failure of emergency therapy. Age was not a factor. Instead, in addition to attack severity and symptoms between attacks, it was rather the presence of respiratory viral infection or fever triggering the attack that was more often associated with treatment failure, i.e., higher hospitalization rates, more returns to the emergency room, and reduced speed of recovery over the 10 days after discharge. Viral detection occurred more frequently in preschoolers (67%) than in older children (46%) with asthma. Nevertheless, the results confirm the overall effectiveness of standard treatment, adjusted to the severity of the attack and administered early, in the vast majority of children, regardless of age and viral detection. Indeed, although a failure rate of nearly 40% was expected in this group of children with moderate to severe attack, only 17% of the participants did not respond to standard treatment. This rate was significantly higher (19%) in children with viral infection compared to uninfected children (13%).

Response: Long-acting beta-agonists (LABAs) have been shown to increase the risk of asthma-related death among adults and the risk of asthma-related hospitalization among children. It is unknown whether the concomitant use of inhaled glucocorticoids with LABAs mitigates those risks. This trial prospectively evaluated the safety of the LABA salmeterol, added to fluticasone propionate, in a fixed-dose combination in children.

Hill, M.D., Ph.D. Fellow Physician Division of Allergy and Immunology The Children's Hospital of Philadelphia Philadelphia, PA 19104-3375 MedicalResearch.com: What is the background for this study? What are the main findings? Response: Eczema, asthma, allergic rhinitis, and food allergies are among the most common childhood medical conditions in the United States. Importantly, disease rates for these conditions are thought to be changing, prompting the need for continued surveillance. In our study, we examined electronic medical record data of over 1 million children to measure incidence and prevalence rates of these conditions in our community. We found that 1 in 5 children seen in our network are diagnosed with asthma, a rate that is among the highest in the nation. Additionally, the large size of our study allowed us to measure the extent to which food allergies are associated with asthma or allergic rhinitis. In this analysis, we found that children with food allergies are 2 to 3 times more likely to develop asthma or allergic rhinitis, as compared with children without food allergy.

What are the main findings? Response:  Acetaminophen (e.g., Tylenol, Panadol) and ibuprofen (e.g., Advil, Motrin) are the only available treatments for pain and fever in toddlers and the most commonly utilized medications worldwide. Recently there has been controversy and even alarm with suggestive observational data that acetaminophen makes asthma worse. This has led some experts to recommend the avoidance of acetaminophen in children with asthma. We sought to find the answer to this burning question through the first prospective, double-blind, randomized clinical trial comparing acetaminophen versus ibuprofen head to head for use when clinically indicated for fever or pain. Is there a difference in asthma morbidity (exacerbations) in young children between the age of 12-59 months, who have asthma?

Response: By probing the differences between two farming communities—the Amish of Indiana and the Hutterites of South Dakota—our interdisciplinary team (which included, among others, Erika von Mutius from Ludwig-Maximilians University in Munich, Carole Ober and Anne Sperling from the University of Chicago, and myself) found that substances in the house dust from Amish, but not Hutterite, homes shape the innate immune system in ways that may prevent the development of allergic asthma. Growing up in a microbe-rich farm environment has been known to protect against asthma. Our current study extends these findings by showing that in both humans and mice protection requires engagement of the innate immune system. The Amish and Hutterite farming communities in the United States, founded by immigrants from Central Europe in the 18th and 19th centuries, provide textbook opportunities for comparative studies. The Amish and the Hutterites have similar genetic ancestry and share lifestyles (e.g., family size, diet, lack of exposure to indoor pets) known to affect asthma risk. However, their farming practices differ. The Amish have retained traditional methods, live on single-family dairy farms and rely on horses for fieldwork and transportation. In contrast, the Hutterites live on large communal farms and use modern, industrialized farm machinery. This distances young Hutterite children from the constant daily exposure to farm animals.
