BACKGROUND Acute wheezing illnesses in preschoolers require better management strategies to reduce morbidity. OBJECTIVES We sought to examine the effectiveness of episodic use of an inhaled corticosteroid and a leukotriene receptor antagonist in preschoolers with intermittent wheezing. METHODS In a randomized, double-blind, placebo-controlled 12-month(More)
RATIONALE Stress-elicited disruption of immunity begins in utero. OBJECTIVES Associations among prenatal maternal stress and cord blood mononuclear cell (CBMC) cytokine responses were prospectively examined in the Urban Environment and Childhood Asthma Study (n = 557 families). METHODS Prenatal maternal stress included financial hardship, difficult life(More)
BACKGROUND More evidence is needed on which to base recommendations for treatment of mild-moderate persistent asthma in school-aged children. OBJECTIVE The Pediatric Asthma Controller Trial (PACT) compared the effectiveness of 3 regimens in achieving asthma control. METHODS A total of 285 children (ages 6-14 years) with mild-moderate persistent asthma(More)
Pediatric asthma remains an important public health concern as its prevalence and cost to the health care system is rising. In order to promote innovative research in asthma therapies, the National Heart, Lung and Blood Institute created the Childhood Asthma Research and Education Network in 1999. As its first study, the steering committee of the Childhood(More)
Studies of asthma admissions in the St. Louis metropolitan area have disclosed substantial numbers of children with readmissions. To determine the magnitude of readmissions and attributes of children with readmissions, a retrospective analysis of 8,761 children with 14,905 asthma hospitalizations for January 1, 1990 through December 31, 1999 at the two(More)
BACKGROUND Responses to inhaled corticosteroids (ICSs) and leukotriene receptor antagonists (LTRAs) vary among asthmatic patients. OBJECTIVE We sought to determine whether responses to ICSs and LTRAs are concordant for individuals or whether asthmatic patients who do not respond to one medication respond to the other. METHODS Children 6 to 17 years of(More)
Morbidity and mortality due to asthma continues to increase despite advances in understanding the pathophysiology and treatment of the disease. We evaluated the potential risk factors for asthma morbidity and mortality in a large metropolitan city (St. Louis, MO) using small area geographic analysis. We found that the risk of hospitalization for children(More)
BACKGROUND Preliminary evidence is equivocal about the role of exhaled nitric oxide (NO) in clinical asthma management. We aimed to assess whether measurement of exhaled NO, as a biomarker of airway inflammation, could increase the effectiveness of asthma treatment, when used as an adjunct to clinical care based on asthma guidelines for inner-city(More)
