Two long-acting ß 2 -adrenergic agonists (LABAs), salmeterol and formoterol, have been demonstrated to be safe and effective agents in children, both in terms of bronchodilation and prevention of exercise-induced bronchospasm. Their onsets of action differ, with formoterol having an onset similar to albuterol (3 minutes), while salmeterol has a slower onset of action (10–20 minutes). Following a single-dose administration, both agents demonstrate durations of action up to 12 hours. Following regular twice-daily administration, bronchodilation remains effective; however, a level of tolerance (or tachyphylaxis) (more…)

Exposure and allergic sensitization to cockroach was associated with a significantly greater risk of asthma hospitalization and greater healthcare utilization among 476 children aged 4 to 9 years who participated in the National Cooperative Inner-City Asthma Study. Allergic sensitization to the mold Alternaria has been identified as a significant allergen in terms of increasing airway hyperresponsiveness and was associated with a nearly 200-fold increased risk of respiratory arrest due to asthma, emphasizing the importance of determining underlying allergic sensitivities in patients with asthma and providing patients with accurate and practical advice on allergen avoidance techniques.

More severe asthma can persist from childhood into adulthood without remission. Another important tendency in the natural history is for symptoms to remit in adolescence only to return again in adulthood. In general, the amount of wheezing in early adolescence seems to be a guide for severity in early adult years, with 73% of those with few symptoms at age 14 years continuing to have little or no asthma progression at age 28 years. Similarly 68% of those with frequent wheezing at 14 years still suffered from recurrent asthma at age 28 years. Most subjects with frequent wheezing at 21 years continued to have comparable asthma at 28 years. In addition to the importance of symptoms in childhood, childhood degree of bronchial responsiveness in combination with a low FEV-1 were also related to the outcome of asthma in adulthood. (more…)

Leukotrienes can be found in the airway and urine following both spontaneous exacerbations of asthma and acute exposure to bronchoconstrictor stimuli in the laboratory. This in turn indicates that they may have a role in the pathogenesis of acute episodes of bronchoconstriction. Although antileukotrienes are not currently advocated in the management of acute asthma, there are data to suggest that they might be of some potential benefit. Prior treatment with montelukast asthma has been shown in several studies to significantly shorten the time taken to recover (in terms of FEV 1 ) following exposure to a bronchoconstrictor stimulus.

In 2004, there were 2.4 million children aged 5 to 14 years, or 5.9% of this population group, with a self-reported asthma attack, with no decrease in prevalence since 1997 1 in spite of the much improved therapies available. In this interval, the number of physician office visits for asthma doubled, from 1.7 to 3.3 million which many leads to asthma morbidity and asthma mortality. (more…)

In the UK, Europe and the USA, montelukast is licensed for once-daily oral administration in adults and is also available as a cherry flavored pink tablet or as granules for use in children over the age of 6 months. Zafirlukast is licensed for use in individuals over 12 years of age (Fig above). In some countries such as Japan, another leukotriene receptor antagonists (LTRA), pranlukast, is available for use. In the USA, zileuton is licensed for use in those over 12 years of age (Table below). (more…)

Negative family characteristics such as family conflict and family dysfunction discriminated children who died of asthma from children with equally severe asthma who did not die. Parenting difficulties have been associated with a higher risk for the development of asthma early in life. In addition, children with the highest risk of developing early-onset asthma were those in families with both parenting problems and high stress. Evidence for a asthma and stress link has been demonstrated through temporal studies, as experiencing an acute negative life event increased children’s risk for an asthma attack 4 to 6 weeks after the occurrence of the event.

Two main strategies have been developed to block the effects of cysteinyl leukotrienes in the airway. One method is to use drugs that prevent their synthesis (using a 5-lipoxygenase inhibitor) and the other involves interfering with the binding of cysteinyl leukotrienes to their cellular receptor using a leukotriene receptor antagonist (LTRA).

The immunologic mechanisms of sublingual immunotherapy are less established. In Cochrane analysis, the authors concluded that there was an increase in IgG4 but no stable effect on IgE levels in adults. In addition, the induction of allergen-specific IgA has been reported. There are conflicting data concerning lympho-proliferative responses. So far the evidence on changes in Th1/Th2/Treg activity induced by sublingual immunotherapy need to be confirmed. The effects on T-cell reactivity and cytokine secretion show strong variation in a number of studies. (more…)
