When asthma and rhinitis coexist, could rhinitis reduce asthma control in children?
Bronchial asthma and rhinitis are among the most common diseases in children and frequently coexist in the patient. The primary aim of anti-asthmatic therapy is disease control. Several questionnaires can be used in pediatrics to assess asthma control and the Children Asthma Control Test (C-ACT) is one of the most used.
To evaluate the percentage of asthma control in our cohort of patients with asthma and correlate C-ACT with bronchial and nasal function tests.
We enrolled all children ages between 5 and 11 years with persistent bronchial asthma, sensitized to dust mite, and who presented to our center during an 8-month period. All the children had skin-prick tests, spirometry, measurement of fractional exhaled nitric oxide levels, active anterior rhinomanometry, measurement of nasal nitric oxide level, and C-ACT.
Sixty patients were enrolled; 80% of these children had rhinitis. According to C-ACT, 31% of our patients had uncontrolled asthma. Nasal flow values were significantly lower in patients with uncontrolled asthma, who also had higher nasal inflammation.
The disease is not controlled in a significant percentage of children with asthma. In patients with uncontrolled asthma, worse nasal flow was detected. These results supported the relationship between upper and lower airways, and highlighted the importance of performing nasal function tests in all patients with asthma, which could be useful to determine whether better control of asthma symptoms can be reached through an appropriate treatment of rhinitis.

- Allergy and Asthma Proceedings is a peer reviewed publication dedicated to distributing timely scientific research regarding advancements in the knowledge and practice of allergy, asthma and immunology. Its primary readership consists of allergists and pulmonologists.
The goal of the Proceedings is to publish articles with a predominantly clinical focus which directly impact quality of care for patients with allergic disease and asthma and by having the potential to directly impact the quality of patient care. AAP welcomes the submission of original works including peer-reviewed original research and clinical trial results. Additionally, as the official journal of the Eastern Allergy Conference (EAC), AAP will publish content from EAC poster sessions as well as review articles derived from EAC lectures.
Featured topics include asthma, rhinitis, sinusitis, food allergies, allergic skin diseases, diagnostic techniques, allergens, and treatment modalities. Published material includes peer-reviewed original research, clinical trials and review articles.
Articles marked "F" offer free full text for personal noncommercial use only.
The journal is indexed in Thomson Reuters Web of Science and Science Citation Index Expanded, plus the National Library of Medicine's PubMed service.
