Adolescents randomized to the ASMA school-based intervention (education and self-assessment tools for kids & their providers) had better control of their asthma on multiple hard and soft outcome measures, compared to kids getting usual care, Bruzzese et al report. (n=345).AJRCCM 2011;183:998-1006.
Busse et al randomized 419 inner-city kids (age 6-20) with uncontrolled, skin-test-positive, mostly severe allergic asthma and IgE < 1,300 IU/mL to 60 weeks of omalizumab or placebo. The treated group had modest improvements: ~1 fewer day of symptoms per month and a 5% absolute reduction in hospitalizations (1.5% vs 6.3%); 18% fewer of them [… read more]
After analyzing all AstraZeneca’s clinical trials data on budesonide for asthma (26 placebo-controlled, n~14,000; 60 non-placebo-controlled, n~33,000), O’Byrne et al found no increased risk of pneumonia with use of budesonide by asthmatics, who contracted 1-2 detected pneumonias per 100 patient-years of treatment. AJRCCM 2011;183:589-595.

People (n=21) with inadequately controlled asthma in a supervised exercise program for 12 weeks followed by self-motivated exercise for 12 weeks had “clinically significant” 0.5-point lower scores on the Asthma Control Questionnaire, as well as improved aerobic fitness, compared to 16 nonrandomized matched controls. Astonishingly, no serious trial testing exercise in asthma control has ever [… read more]
Daily inhaled corticosteroids (ICS) may retard growth in children, who would rather play than take daily inhalers. Martinez et al randomized children with mild persistent asthma to four groups, one of which was beclomethasone + albuterol as rescue therapy only (i.e., no daily ICS), for 44 months. They did slightly worse than children taking daily [… read more]
Ciclesonide, a new inhaled corticosteroid that seems to cause thrush less often than others, reached for equivalency with salmeterol/fluticasone in mild persistent asthma. Ciclesonide was better than placebo in controlling asthma but Advair users had a longer time to first asthma exacerbation. CHEST 2011;139: online supplement. A Cochrane review on ciclesonide could not establish its [… read more]
The hygiene hypothesis got a boost from Ege et al, who analyzed dust from 16,000 European children’s bedrooms and mattresses (stored with clinical/demographic data in two huge repositories, GABRIELA and PARSIFAL), for bacterial DNA or growth on bacterial/fungal culture media. Children living on farms had odds ratios for asthma of 0.49 to 0.76, compared to [… read more]
