Abstract

Background Few studies have examined the effects of in utero smoke exposure (IUS) on lung function in children with asthma, and there are no published data on the impact of IUS on treatment outcomes in children with asthma.Objectives To explore whether IUS exposure is associated with increased airway responsiveness among children with asthma and whether IUS modifies the response to treatment with inhaled corticosteroids (ICSs).Methods To assess the impact of parent-reported IUS exposure on airway responsiveness in childhood asthma, we performed a repeated-measures analysis of methacholine PC(20) data from the Childhood Asthma Management Program, a 4-year, multicenter, randomized, double-masked, placebo-controlled trial of 1041 children age 5 to 12 years comparing the long-term efficacy of ICS with mast cell stabilizing agents or placebo.Results Although improvement was seen in both groups, children with asthma and IUS exposure had on average 26% less of an improvement in airway responsiveness over time compared with unexposed children (P = .01). Moreover, while children who were not exposed to IUS who received budesonide experienced substantial improvement in PC(20) compared with untreated children (1.25-fold increase; 95% CI, 1.03-1.50; P = .02), the beneficial effects of budesonide were attenuated among children with a history of IUS exposure (1.04-fold increase, 95% CI, 0.65-1.68; P = .88).Conclusion In utero smoke exposure reduces age-related improvements in airway responsiveness among children with asthma. Moreover, IUS appears to blunt the beneficial effects of ICS use on airways responsiveness. These results emphasize the importance of preventing this exposure through smoking cessation counseling efforts with pregnant women.

  • SHS exposure may impair the effectiveness of corticosteroids used for the treatment of small airway disease.

    “SHS exposure may also impair the effectiveness of corticosteroids used for the treatment of small airway disease.21”

    From Impact of Tobacco Smoke and Nicotine Exposure on Lung Development (2016) · cites this paper as [21]

    The Results and Discussion report that children with asthma exposed to tobacco smoke in utero had a blunted response to inhaled budesonide. The claim extends that finding to SHS exposure generally and to treatment of small airway disease, neither of which the study establishes; current environmental tobacco smoke exposure was adjusted for, not identified as the exposure driving the result.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
