Abstract:
Adenoids removed for airway obstruction and-or recurrent infections have been studied to identify a possible mechanism to explain chronicity. In this regard, macrophages may play a relevant pathogenic role as well as neutrophils during bacterial infections and eosinophils in allergic inflammation. Therefore, this study aimed at investigating some mediators as surrogate markers of inflammation in children who had to undergo to adenoidectomy. Globally, 67 children (25 females, 42 males, mean age 4.9 years), affected by persistent obstruction caused by adenoid hypertrophy were consecutively enrolled into the study. Blood samples were collected from patients and controls to determine serum CD163, Myeloperoxidase (MPO) and ECP. There were significant differences between patients and controls for serum CD163 (p less than 0.0001); MPO (p less than 0.0001); serum ECP (p less than 0.0001). This study demonstrated some risk factors for severe AH: apnoea, recurrent respiratory infections, and high serum CD163 levels.
Insights
This study found that high levels of serum CD163, along with apnea and recurrent respiratory infections, are risk factors for severe adenoid hypertrophy in children. These findings help understand the inflammation mechanisms behind this condition.
Area of Science:
- Pediatric Otolaryngology
- Immunology
- Respiratory Medicine
Background:
- Adenoid hypertrophy (AH) is a common condition in children, often leading to airway obstruction and recurrent infections.
- The underlying mechanisms of chronic inflammation in AH are not fully understood.
- Macrophages, neutrophils, and eosinophils may play roles in the pathogenesis of AH.
Purpose of the Study:
- To investigate serum levels of inflammation markers in children undergoing adenoidectomy.
- To identify potential surrogate markers for inflammation in adenoid hypertrophy.
- To explore risk factors associated with severe adenoid hypertrophy.
Main Methods:
- A study was conducted on 67 children (mean age 4.9 years) with persistent obstruction due to adenoid hypertrophy.
- Blood samples were collected from patients and controls.
- Serum levels of CD163, Myeloperoxidase (MPO), and Eosinophil Cationic Protein (ECP) were measured.
Main Results:
- Significant differences were observed in serum CD163, MPO, and ECP levels between children with AH and controls (p < 0.0001 for all).
- High serum CD163 levels were identified as a significant risk factor for severe AH.
- Apnea and recurrent respiratory infections were also identified as risk factors for severe AH.
Conclusions:
- Serum CD163, MPO, and ECP levels are significantly elevated in children with adenoid hypertrophy.
- Elevated serum CD163, presence of apnea, and recurrent respiratory infections are risk factors for severe AH.
- These mediators may serve as valuable markers for assessing inflammation in pediatric adenoid disease.

Chronic Pharyngitis
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants.
