Serum periostin is a potential biomarker of response to therapies that target type 2 inflammation in asthma. The objectives of this study were to describe: 1) the distribution of serum periostin levels in adults with symptomatic airflow obstruction; 2) its relationship with other variables, including type 2 biomarkers; and 3) the effect of inhaled corticosteroids on periostin levels.Serum periostin levels were measured in a cross-sectional study exploring phenotypes and biomarkers in 386 patients aged 18-75 years who reported wheeze and breathlessness in the past 12 months. In 49 ICS-naïve patients, periostin levels were measured again after 12 weeks of budesonide (800 μg·day(-1)).The distribution of serum periostin levels was right skewed (mean±sd 57.3±18.6 ng·mL(-1), median (interquartile range) 54.0 (45.1-65.6) ng·mL(-1), range 15.0-164.7 ng·mL(-1)). Periostin was positively associated with exhaled nitric oxide (Spearman's rho=0.22, p<0.001), blood eosinophil count (Spearman's rho=0.21, p<0.001), and total IgE (Spearman's rho=0.14, p=0.007). The Hodges-Lehmann estimator (95% CI) of change in periostin level after ICS therapy was -4.8 (-6.7- -3.2) ng·mL(-1) (p<0.001).These findings provide data on the distribution of serum periostin in adults with symptomatic airflow obstruction, the weak associations between periostin and other type 2 markers, and the reduction in periostin with inhaled corticosteroid therapy.

Attention Score in Context
Attention Score in Context
This research output has an Altmetric Attention Score of 9. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 06 June 2016.
All research outputs
#4,758,758
of 28,574,713 outputs
Outputs from European Respiratory Journal
#3,344
of 9,987 outputs
Outputs of similar age
#62,051
of 317,884 outputs
Outputs of similar age from European Respiratory Journal
#41
of 135 outputs
Altmetric has tracked 28,574,713 research outputs across all sources so far. Compared to these this one has done well and is in the 83rd percentile: it's in the top 25% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 9,987 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 16.3. This one has gotten more attention than average, scoring higher than 66% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 317,884 tracked outputs that were published within six weeks on either side of this one in any source. This one has done well, scoring higher than 80% of its contemporaries.
We're also able to compare this research output to 135 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 69% of its contemporaries.
