BACKGROUND The use of Childhood Asthma Control Test (C-ACT) has been advised for monitoring asthma control by the Global Initiative for Asthma (GINA) guidelines. OBJECTIVE To validate the tool C-ACT for the assessment of control of asthma and to examine the correlation between C-ACT score and lung function assessed by forced expiratory volume in one second (FEV1). METHODS This was a prospective observational study conducted between January 2010 to January 2011. Children diagnosed to have bronchial asthma and aged 5 to 14 years, were enrolled in the study. Asthma severity and control status were classified according to the National Asthma Education and Prevention Programme (NAEPP) and GINA guidelines, respectively. Patients were followed-up at three and six months and C-ACT and spirometric measurements were obtained. RESULTS Significant positive correlations were found between C-ACT score and FEV1 at enrollment (r = 0.772) (p < 0.001), three months (r = 0.815) (p < 0.001) and at six months follow-up (r = 0.908) (p < 0.001). Baseline C-ACT score was useful for predicting the levels of control of asthma upto three months (0.004), but not at six months follow-up (0.787). A cut-off C-ACT value of > or = 19 had a sensitivity, specificity, positive predictive value, negative predictive value and area under the curve (AUC) 98.5%, 89.1%, 94.9%, 96.6%, 0.717, respectively for the control of asthma. CONCLUSION C-ACT is a simple and feasible tool to assess and predict the levels of control in children with bronchial asthma upto three months.

Determination the Role of Endothelial Cell-Specific Molecule-1(ESM-1) in Childhood Bronchial Asthma

  Background Endothelial Cell-Specific Molecule-1 (ESM-1) is a 50 kDa soluble proteoglycan that is produced mainly the vascular endothelial cells of the kidney and lung. It is produced by the effects of proangiogenic and pro-inflammatory cytokines, and it indicates activation and dysfunction of the vascular endothelium. We aimed to detect the role of ESM-1 in childre...

IL-23 Gene and Protein Expression in Childhood Asthma

Background: Asthma is the chronic inflammation of airways characterized by eosinophilic infiltration, mucus overproduction, airway hyper-responsiveness and airway remodeling. These changes are induced mostly by cytokines which are produced by T helper (Th) 2 cells. Recently, the role of interleukin-23 (IL-23) in the pathogenesis of adultallergic asthma has been studied. Objective: To explore IL...
