A clinical description of asthma and its prevalence

Health characteristics of patients with asthma, COPD and asthma–COPD overlap in the NHANES database

When asked about her own history, Laura recalls periodic episodes of wheezing and coughing when she was a young girl, but she was never screened for asthma.

The pool of potential study participants in the Pediatric Asthma Clinical Research Network should include children ages years and consist of appropriate gender approximately 50 percent women and minority approximately 30 percent representation.

A separate Data Coordinating Center will support protocol development and provide sample size calculations, statistical advice, common questionnaires, data analysis, and overall study coordination and quality assurance.

It will also be important to include strategies to assure adherence to therapy as part of the protocol. Asthma symptoms vary from patient to patient. It is known that fat tissue produces inflammatory substances, and a number of studies have suggested these substances contribute to asthma.

Under normal conditions, mucus protects the airways and moistens the air. Children born to mothers who smoked have a higher asthma prevalence risk. Asthma epidemics have occurred under such circumstances and have affected people who have never had asthmatic symptoms before.

Samples were tested for dust mite, cockroach, cat, and dog allergens. The prevalence of asthma in children in New Zealand and Australia has been reported to be higher than that found in other countries 3.

Asthma is one of the most common chronic conditions affecting both children and adults, yet much remains to be learned of its etiology. During normal vaginal delivery the infant is exposed to a microbiome different from the one encountered during a cesarean section in an operating room.

Studies have also shown that people with asthma and a BMI over 30 do not respond to medications in the same way that those with lower BMI.

Asthma Patient Care

This can occur more than 30 times in a typical night, and the person may be unaware of it. Data Coordinating Center Applicants: The exact number is not clear. These smaller grains contain allergens of the right size to reach the bronchial tree, resulting in asthma symptoms.

Alpha-tocopherol is found in olive oil, wheat germ, and almond and sunflower oils and has been found to have beneficial effects on lung function. For example, asthma hospitalization rates are highest among persons age years, and have increased over 28 percent in the last 15 years; mortality rates increased faster among those aged 5 to years than among those age years and neither changes in disease coding nor improved recognition of asthma fully explain these increases.

During a thunderstorm, however, these grains are carried up by a dry updraft, ruptured by high humidity at the cloud base, and then forced down by colder air. The authors noted that part of this increase may have been due to increased awareness of both asthma and the symptom of wheeze by health care providers and the public.

Using a self-administered questionnaire, they found significant increases in both populations in the prevalence of doctor diagnosed asthma, recent use of an asthma drug, and episode of wheeze.

Materials are not available for widespread distribution.

Children with Asthma

The letter of intent is to be faxed or mailed to Dr. Annals of Allergy, Asthma, and Immunology. Bottrell, Bacterial Infections Chlamydia pneumonia is a bacterium known for causing bronchitis and pneumonia.

An algorithm was developed that described an entire hospital-based asthma encounter from presentation in the emergency setting through an inpatient stay and, finally, to discharge planning. In year-old Swedish military conscripts, the prevalence of asthma increased from 1.

The review was updated in July RhLF's anti-asthma activity appears to act by a novel mechanism. A genetic deficiency in the plasma antioxidant platelet-activating factor acetylhydrolase PAF-AH has been shown to play a role in inflammatory diseases including asthma.

The accuracy of the self-reported data was not verified or verifiable through medical records or other sources. Women should be counseled to eat a healthy diet during pregnancy, which includes plenty of fruits and vegetables as well as whole grains, low-fat dairy, a variety of proteins, and oils and foods containing alpha-tocopherol.

People with a BMI of 30 or more have a much higher risk of having asthma. Learn More Exercise Induced Asthma If you start wheezing or coughing during exercise, or if physical exertion makes it difficult for you to breathe, you may have exercise-induced bronchoconstriction, or EIB.

Effects beyond one year are unknown. The effect was similarly evaluated in New Zealand year olds, and an expected increase of just 2. Interventions included education and use of clinical practice guidelines. Lung function tests and computed tomography CT scans can help distinguish cough-variant asthma from other causes of cough.

Yet the burden of asthma disproportionately affects children. To enable comparisons across a standardized age, an asthma subgroup age-matched to the ACO group was also used and comprised participants.

Statistical analysis Descriptive statistics included mean, standard deviation, and median values for continuous data, and frequencies and proportions for categorical data. Their analyses of data regarding admissions for lower respiratory tract disease and bronchitis showed decreases that suggested diagnostic transfer may have contributed in part to increased hospitalizations.

Introduction. Asthma is a heterogeneous, complex and common chronic respiratory disease that affects over million people worldwide, resulting in a considerable clinical and socio-economic burden.

This is mainly due to clinical studies excluding participants meeting the description of ACO.

Allergic Asthma

1,7,9 To van den Berge M, Aalbers R. The asthma-COPD overlap syndrome: how is it defined and what are its clinical implications? J Asthma Allergy Mincheva R, Hagstad S, et al. Prevalence, clinical characteristics and morbidity of the Asthma. Sex specific differences in prevalence of allergic rhinitis and asthma over the life span were recognized, showing a higher prevalence of allergic rhinitis and asthma as single entities in boys than in girls during childhood followed by an equal distribution in adolescence [2, 3].

Data, Statistics, and Surveillance

Chronic respiratory diseases are a group of chronic diseases affecting the airways and the other structures of the lungs. Common chronic respiratory Figure 4 World map of the prevalence of clinical asthma Proportion of population (%) Source: reference.

DESCRIPTION (provided by applicant): The purpose of this research is to determine the efficacy of orally administered recombinant human lactoferrin (rhLF) in Phase II clinical trials in patients with mild to moderate asthma.

Children with sensitization had a higher prevalence of symptoms of asthma and eczema (two to three times more common) and a higher prevalence of reported physicians’ diagnoses of food allergy and asthma than non-sensitized children.
