Livelli di periostina nei bambini con ipertrofia adenoide

16 settembre 2026 aggiornato da: Bezmialem Vakif University

This prospective observational study evaluated serum and tissue periostin levels in children with adenoid hypertrophy. Children with grade 3-4 adenoid hypertrophy who were scheduled for adenoidectomy were compared with children with grade 1 adenoid hypertrophy without symptoms attributable to adenoid enlargement. Serum periostin levels were compared between the two groups. In the adenoidectomy group, periostin levels in adenoid tissue were also compared with paired samples of normal nasopharyngeal mucosa obtained from the same patients. The study aimed to investigate whether periostin may be associated with the development of adenoid hypertrophy and to explore its potential role in local tissue remodeling.

Descrizione dettagliata

Adenoid hypertrophy (AH) is a common condition in children and may result in nasal obstruction, mouth breathing, sleep-disordered breathing, recurrent upper respiratory symptoms, and other related clinical manifestations. Although allergic inflammation has been proposed as one of the mechanisms contributing to adenoid hypertrophy, the pathophysiological mechanisms underlying tissue enlargement are multifactorial and remain incompletely understood. Periostin is a matricellular protein involved in extracellular matrix organization and tissue remodeling and has been associated with inflammatory and remodeling processes in several airway diseases. However, limited information is available regarding the role of periostin in adenoid hypertrophy.

This prospective observational study was designed to investigate serum and local tissue periostin levels in children with adenoid hypertrophy. The study included children aged 2-8 years who were evaluated for adenoid hypertrophy. The adenoid hypertrophy group consisted of children with grade 3-4 adenoid hypertrophy who were scheduled for adenoidectomy based on their clinical condition. The control group consisted of children with grade 1 adenoid hypertrophy (0-25% nasopharyngeal obstruction) who had no symptoms attributable to adenoid enlargement.

Serum periostin levels were measured in both groups and compared between children with grade 3-4 and grade 1 adenoid hypertrophy. In children undergoing adenoidectomy, adenoid tissue samples were obtained during the clinically indicated surgical procedure. Paired samples of normal nasopharyngeal mucosa were also obtained from the posterior pharyngeal wall of the same patients. Periostin concentrations in adenoid tissue and paired normal nasopharyngeal mucosa were measured and compared using a within-subject paired analysis. No tissue samples were obtained from the control group.

The primary objective was to determine whether serum periostin levels differ between children with clinically significant adenoid hypertrophy and children with grade 1 adenoid hypertrophy without symptoms attributable to adenoid enlargement. A secondary objective was to evaluate whether periostin expression is increased locally in adenoid tissue compared with paired normal nasopharyngeal mucosa in the same patients.

The study was conducted prospectively after obtaining approval from the institutional ethics committee (Approval No. 8/8.11.04.18), and written informed consent was obtained from the legal guardians of all participants. The study was conducted in accordance with the principles of the Declaration of Helsinki.

Popolazione di studio

The study population consisted of 37 children aged 2-8 years. The study group included 19 children with grade 3-4 adenoid hypertrophy who were scheduled for adenoidectomy due to clinical indications. The control group included 18 children with grade 1 adenoid hypertrophy and no symptoms attributable to adenoid enlargement. All participants had previously documented negative skin prick test results. Children with a history of allergic rhinitis, asthma, immunodeficiency, chronic systemic or endocrine disease, recent upper respiratory tract infection, or prior adenoid surgery were excluded. Serum samples were obtained from all participants, while adenoid tissue and paired normal nasopharyngeal mucosal samples were obtained only from children undergoing adenoidectomy

Intervento / Trattamento
Adenoid Hypertrophy (Grade 3-4)

Children aged 2-8 years with grade 3-4 adenoid hypertrophy who were scheduled for adenoidectomy based on their clinical condition. Serum periostin levels were measured in this group. Adenoid tissue and paired normal nasopharyngeal mucosa samples were obtained from the same patients during the clinically indicated surgical procedure for tissue periostin analysis.

The serum periostin levels were planned to compare between the serum samples that were obtained from the two groups. The evaluation of the periostin levels of adenoid tissue and normal healthy mucosa were also planned.

Control (Grade 1 Adenoid Hypertrophy)

Children aged 2-8 years with grade 1 adenoid hypertrophy (0-25% nasopharyngeal obstruction) who had no symptoms attributable to adenoid enlargement. Serum periostin levels were measured for comparison with the adenoid hypertrophy group. No adenoid tissue samples were obtained from participants in this group.

The serum periostin levels were planned to compare between the serum samples that were obtained from the two groups. The evaluation of the periostin levels of adenoid tissue and normal healthy mucosa were also planned.
