Insights

Persistent allergic rhinitis in children is significantly associated with otitis media with effusion (OME) and delayed mucociliary transport time. Middle ear effusion also showed higher eosinophil cationic protein (ECP) levels in persistent cases.

Area of Science:

  • Pediatric Otolaryngology
  • Allergy and Immunology
  • Pediatric Respiratory Medicine

Background:

  • The link between middle ear pathology and nasal allergies has been a long-standing debate.
  • Otitis media with effusion (OME) is a common pediatric condition, and allergic rhinitis affects a significant portion of children.
  • Understanding the interplay between these conditions is crucial for effective diagnosis and management.

Purpose of the Study:

  • To investigate the relationship between otitis media with effusion (OME) and persistent allergic rhinitis symptoms compared to intermittent rhinitis in children.
  • To evaluate specific clinical and immunological markers associated with OME in children with allergic rhinitis.

Main Methods:

  • A cohort of 100 atopic children aged 5-9 years with otological symptoms underwent comprehensive ear, nose, and throat evaluations.
  • Diagnostic tools included tympanometry, skin prick tests (SPTs) for allergens, mucociliary transport time (MCTt) measurements, and Eustachian tube function tests.
  • Middle ear effusion analysis included eosinophil cationic protein (ECP) levels.

Main Results:

  • Skin prick tests identified sensitization to common allergens like Dermatophagoides pteronyssinus, grass pollen, and Parietaria.
  • A significant proportion of children experienced moderate to severe symptoms, with a notable number having persistent rhinitis.
  • Delayed mucociliary transport time (MCTt) was observed in children with persistent rhinitis (21 ± 2 mins) compared to intermittent rhinitis (16 ± 2 mins) (P <0.01).
  • Middle ear effusion was present in 45 children, and significantly elevated eosinophil cationic protein (ECP) levels were found in middle ear effusions (251 ± 175.2 μg/L) and blood (25.5 ± 16.3 μg/L) (P < 0.001).

Conclusions:

  • A significant association exists between otitis media with effusion (OME), delayed mucociliary transport time, and elevated eosinophil cationic protein (ECP) levels in middle ear effusions of children with persistent allergic rhinitis.
  • These findings suggest that the middle ear mucosa may act as a direct target organ in the pathophysiology of persistent allergic rhinitis in children.

Microbiota of the Respiratory Tract

The human respiratory tract, comprising the upper and lower segments, serves as a critical interface with the external environment. The upper respiratory tract (URT)—including the nostrils, sinuses, pharynx, and oropharynx—is heavily colonized by microbes, while the lower respiratory tract (LRT), composed of the larynx, trachea, bronchi, and lungs, was long thought to be sterile. However, recent molecular studies have revealed that the lungs are not devoid of microbes but act more...

Asthma I: Introduction01:28

Asthma I: Introduction

Asthma is a chronic inflammatory disorder of the airways characterized by variable airflow obstruction and heightened bronchial responsiveness to a wide range of triggers. The underlying inflammation leads to airway swelling, mucus hypersecretion, and smooth muscle constriction, all of which narrow the airway lumen and impede airflow. Clinically, asthma presents with recurrent episodes of wheezing, shortness of breath, chest tightness, and coughing, symptoms that typically vary in intensity and...

Olfactory Receptors: Location and Structure01:03

Olfactory Receptors: Location and Structure

The process of olfaction, also known as the sense of smell, is a sophisticated chemical response system. The specialized sensory neurons that facilitate this process, known as olfactory receptor neurons, are situated in an upper segment of the nasal cavity, known as the olfactory epithelium. Olfactory sensory neurons are bipolar, with their dendrites extending from the epithelium's apex into the mucus that lines the nasal cavity. Airborne molecules, when inhaled, traverse the olfactory...

Nose and Nasal Cavity01:24

Nose and Nasal Cavity

The nose is composed of an observable exterior segment (external nose) and an internal segment within the skull known as the nasal cavity (internal nose). The external nose, visible on the face, consists of a framework of bone and hyaline cartilage enveloped in skin and muscle and lined with a mucous membrane. This structure is supported by the frontal bone, nasal bones, and maxillary bone and is supplemented by a cartilaginous framework comprising the septal nasal cartilage, lateral nasal...

Drugs Used in Upper Respiratory Disorders: Overview

Upper respiratory tract disorders, including viral infections and allergic rhinitis, cause significant discomfort and disrupt daily life. Managing these conditions involves a variety of drugs, such as antihistamines, intranasal steroids, decongestants, antitussives, expectorants, and mucolytics. Specific examples of drugs in each category are provided.
Antihistamines (e.g., Benadryl) block histamines from binding. Histamines are chemicals released during an allergic reaction in the body. As a...
