Dietary Fatty Acid Modification in The Childhood Asthma Prevention Study

Two factors thought to influence the risk factor asthma are the promoting effect of sensitization to house dust mites and the preventive effect of increased omega-3 fatty acids. Although the avoidance of house dust mites allergen has been used as a preventive strategy in several trials, the effect of omega-3 fatty acid supplementation in the primary prevention of asthma and allergic disease is not known.

The Canadian Childhood Asthma Primary Prevention Study

Avoidance of any one of the individual risk factors associated with childhood asthma has not been successful in preventing its development. The purpose of this study was to determine the effectiveness of a multifaceted intervention programme for the primary prevention of asthma in high-risk infants at 7 years of age. Five hundred and forty-five high-risk infants with an immediate family history of asthma and allergies were prospectively randomized into intervention and control groups pre-natally. (more…)

Prevalence of Childhood Asthma and Allergies

Asthma is a complex syndrome rather than a single disease entity. Different phenotypes with varying prognosis and determinants have been described, particularly over childhood years 2 and will be discussed in detail in the following. For example, transient early wheezing is characterized by the occurrence of wheezing in infants up to the age of 2 to 3 years which disappears thereafter. The main predictor of these wheezing illnesses is premorbid reduced lung function before the manifestation of any wheeze. These decrements in pulmonary function are in part determined by passive smoke exposure in utero 4 and result in symptoms of airway obstruction when infants get infected with respiratory viruses.

Environmental Tobacco Smoke and Risk of Asthma

Environmental Tobacco Smoke
The effects of exposure to environmental tobacco smoke (ETS) on children have been extensively studied and numerous surveys have consistently reported an association between environmental tobacco smoke exposure and respiratory diseases or respiratory allergies. Strong evidence exists that passive smoking increases the risk of lower respiratory tract illnesses such as bronchitis, wheezy bronchitis and pneumonia in infants and young children. (more…)

Allergen Exposure And The Development Of Atopic Sensitization

There is much controversy as to the role of allergen exposure for the development of atopic sensitization towards this allergen. While in some studies, a clear, almost linear dose-response relation between allergen exposure and sensitization has been found, others described a bell-shaped association with higher levels of exposures relating to lower rates of atopic sensitization. Part of the discrepancy may relate to the type of allergen, since mostly cat but not house dust mite allergy allergen exposure has been shown, in some studies, to exert protective effects at higher levels of exposure.

The Benefit of Sports and Exercise for Childhood Asthma

exercise asthma

It is very common in asthmatic children where overprotective parents prevent a normal level of exercise to their kids. However, a controlled sport appropriate to the course of their disease is very healthy.

Asthma is an inflammatory disease of the airways characterized by variable bronchial obstruction and reversible, either spontaneously or with treatment, (more…)

Maternal Fish Consumption During Pregnancy & Childhood Asthma

fish asthma
Maternal fish consumption during pregnancy may affect children’s risk of asthma by modulating early-life immune development. The type of fish consumed may be important because of differences in fatty acid content. To test this hypothesis, the authors conducted a nested case–control study, selecting subjects from the Children’s Health Study, a population-based study of school-aged children in southern California. Cases had physician-diagnosed asthma and controls were asthma-free by age 5 years. (more…)

Allergies and Age - When Likely Allergy to Occur the First Time

Allergies can be defined as inappropriate immune system reactions to a foreign substance entering body. Allergies are kind of diseases of immune system works to react to certain substances called allergens. Normally when a person is exposed to a harmless substance such as pollen, causes the body natural immune system to respond as if the substance is harmful. Some allergies are inherited from their parents or can be gained in environmental exposure. There are several common allergen exposures like mold, animal dander, pollen, dust mites, and many others.

Infection and Atopy in the Pathogenesis of Childhood Asthma

infection atopy childhood asthma
It is clear from the results of large epidemiologic studies that while atopy is a major risk factor for asthma, it is usually not sufficient by itself to drive the disease process to chronicity, as less than 25% of atopics develop persistent asthma. The situation in childhood is further complicated by an additional series of development factors, related to postnatal maturation of respiratory function. (more…)

Do Children Grow Out of Asthma?

children grow out asthma
Parents are usually the ones who are greatly affected, when they see their child having an asthma attack. It bothers them so much especially when they can do nothing but comfort their child. It is certainly very painful for any parent to see their child suffering. The question ‘Do children grow out of asthma?’ is often asked by parents to their child’s physician. (more…)
