Efficacy and predictors of response to inhaled corticosteroid treatment for chronic cough.

Korean J Intern Med 2018 Dec 13. Epub 2018 Dec 13.

Lung Research Institute of Hallym University College of Medicine, Chuncheon, Korea.

Background/aims: Inhaled corticosteroids (ICS) are a treatment of choice for eosinophilic airway diseases, but their efficacy for other causes of chronic cough is controversial.

Methods: We conducted a prospective observational study to determine the ICS efficacy and clinical predictors of response to ICS in patients with upper airway cough syndrome (UACS) or unexplained chronic cough (UCC). Sixty-eight patients with UACS and 33 patients with UCC (duration of cough ≥ 8 weeks) were treated with ICS: 250 µg of fluticasone propionate or 400 µg of budesonide twice a day at physician's discretion.

Eosinophil Counts in Mucosal Biopsies of the Ileum and Colon: Interobserver Variance Affects Diagnostic Accuracy.

Patholog Res Int 2018 4;2018:2638258. Epub 2018 Nov 4.

Department of Gastroenterology and Hepatology, University Medical Center Brandenburg, Brandenburg, Germany.

Primary eosinophilic gastroenteritis and colitis (EGE) is a rare entity with unspecific clinical and endoscopic findings. Validated histopathologic criteria for confirming the diagnosis are lacking, because numeric values for normal or elevated concentrations of eosinophils in mucosal biopsies are varying between observers. To quantify this interobserver variance, we had the same set of 30 slides of eosinophilic-rich mucosal biopsies from the ileum and colon systematically reviewed by a panel of six independent pathologists, each with more than a ten-year experience in the field.
