Insights
Children with obstructive sleep apnea (OSA) caused by chronic tonsillitis and adenoid hypertrophy (CT-AH) show lower mean platelet volume (MPV) values. This finding suggests a potential link between CT-AH-induced OSA and altered platelet characteristics in pediatric patients.
Area of Science:
- Pediatric Otolaryngology
- Sleep Medicine
- Hematology
Background:
- Chronic tonsillitis and adenoid hypertrophy (CT-AH) are primary causes of obstructive sleep apnea (OSA) in children, leading to nocturnal hypoxia.
- Limited research exists on the connection between childhood OSA and cardiovascular conditions like atherosclerosis.
- Mean platelet volume (MPV) is an indicator of platelet activation and size, potentially reflecting underlying inflammatory or cardiovascular risks.
Purpose of the Study:
- To investigate the relationship between mean platelet volume (MPV) and CT-AH, a common cause of pediatric OSA.
- To assess if MPV levels differ in children with CT-AH-induced OSA compared to healthy controls.
Main Methods:
- A retrospective study analyzed 200 children diagnosed with CT-AH who underwent adenoidectomy or adenotonsillectomy.
- 240 healthy children served as a control group.
- Blood samples were analyzed for white blood cell count, platelet count, hemoglobin, and mean platelet volume (MPV).
Main Results:
- Children with CT-AH (Groups I and II) exhibited significantly lower MPV values compared to the healthy control group.
- MPV values were 6.6±0.8 fL in the adenoidectomy group and 6.6±0.7 fL in the adenotonsillectomy group, versus 7.3±0.9 fL in controls.
- No significant difference in MPV was observed between the adenoidectomy and adenotonsillectomy groups.
Conclusions:
- Obstructive sleep apnea in children resulting from chronic tonsillitis and adenoid hypertrophy is associated with reduced mean platelet volume.
- Low MPV in this pediatric population may indicate altered platelet function or an increased risk for cardiovascular complications.
- Further research is warranted to explore the long-term implications of these findings on cardiovascular health in children with CT-AH and OSA.
Objectives:
Chronic tonsillitis (CT)-adenoid hypertrophy (AH) is the most common cause of obstructive sleep apnea (OSA), which is one of the most common reasons of nocturnal hypoxia in children. However, there is limited information about the relationship between childhood OSA and atherosclerosis or cardiac diseases. In the present study, we evaluated the relationship between mean platelet volume (MPV) and CT-AH which is the most frequent cause leading OSA in children. Methodology : The medical records of 200 children, who underwent adenoidectomy or adenotonsillectomy with a diagnosis of adenoid hypertrophy and/or chronic tonsillitis between October, 2010 and June, 2012, and 240 healthy controls were evaluated. Subjects were classified into 3 groups. Group I consisted of patients who underwent adenoidectomy, whereas Group II consisted of patients who had adenotonsillectomy. Healthy children were employed as control group. White blood cell count (WBC), platelet count (PLT), hemoglobin (Hb) levels and mean platelet volume (MPV) values were recorded individually.
Results:
MPV values were 6.6±0.8, 6.6±0.7 and 7.3±0.9 in Group I, Group II and control group, respectively. It was found that MPV values in groups I and II were significantly lower than control group. There was no significant difference between group I and II. Conclusion : Obstructive sleep apnea (OSA) caused by CT-AH is associated with low MPV values in childhood.

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.
