Abstract

Aims: This study aimed to investigate whether adenoid hypertrophy-related obstructive sleep apnea syndrome (OSAS) affects hematological inflammatory parameters in children. Specifically, this study focused on evaluating the mean platelet volume (MPV), neutrophil-to-lymphocyte ratio (NLR), and platelet-to-lymphocyte ratio (PLR), which have been proposed as potential biomarkers of systemic inflammation in various pediatric and adult airway disorders. Methods: A retrospective case-control analysis was performed, including children diagnosed with OSAS secondary to adenoid hypertrophy and age-matched healthy controls without respiratory symptoms. Complete blood count parameters, including MPV, platelet, lymphocyte, neutrophil, and white blood cell counts, were obtained from the medical records. Inflammatory markers (NLR and PLR) were calculated and compared between groups. Receiver operating characteristic (ROC) curve analysis was conducted to evaluate the diagnostic performance of the significant hematological markers and to determine the optimal cutoff values. Results: A total of 129 pediatric patients were included in this study. The adenoidectomy group consisted of 61 children, while 68 children who underwent minor urological procedures served as controls. MPV, lymphocyte count, and PLR values did not differ significantly between the groups (p>0.05). However, hemoglobin levels were significantly lower in the OSAS group, whereas platelet count, white blood cell count, neutrophil count, and NLR were significantly higher (p<0.05). ROC analysis showed that NLR had limited diagnostic value, with an AUC of 0.644 and an optimal cutoff value of 0.977. Conclusion: Although MPV and PLR showed no significant variation, the elevated NLR suggests increased systemic inflammation in children with OSAS due to adenoid hypertrophy. Despite its modest diagnostic performance, NLR may be considered an auxiliary inflammatory marker. Further large-scale prospective studies are necessary to better define the diagnostic and prognostic roles of MPV, NLR, and PLR in pediatric airway obstruction.

Özet

ÖZET Amaç: Bu çalışma, adenoid hipertrofisine bağlı obstrüktif uyku apne sendromunun (OSAS) çocuklardaki hematolojik inflamatuvar parametreleri etkileyip etkilemediğini araştırmayı amaçladı. Özellikle, çeşitli pediatrik ve yetişkin hava yolu hastalıklarında sistemik inflamasyonu yansıtan potansiyel biyobelirteçler olarak önerilen ortalama trombosit hacmi (MPV), nötrofil/lenfosit oranı (NLR) ve trombosit/lenfosit oranının (PLR) değerlendirilmesine odaklanıldı. Yöntemler: Adenoid hipertrofisine sekonder OSAS tanısı alan çocuklar ile yaş uyumlu, solunum semptomu olmayan sağlıklı kontrolleri içeren retrospektif bir olgu-kontrol analizi yapıldı. Ortalama trombosit hacmi (MPV), trombosit sayısı, lenfosit sayısı, nötrofil sayısı ve lökosit sayısı dahil olmak üzere tam kan sayımı parametreleri tıbbi kayıtlardan elde edildi. İnflamatuvar belirteçler (NLR ve PLR) hesaplandı ve gruplar arasında karşılaştırıldı. Anlamlı hematolojik belirteçlerin tanısal performansını değerlendirmek ve optimal kesim değerlerini belirlemek için ROC eğrisi analizi gerçekleştirildi. Bulgular: Toplam 129 pediatrik hasta çalışma kapsamına alındı. Adenoidektomi grubunda 61 çocuk bulunurken, küçük ürolojik işlemler geçiren 68 çocuk kontrol grubunu oluşturdu. MPV, lenfosit sayısı ve PLR değerleri gruplar arasında anlamlı fark göstermedi (p > 0.05); bu durum, pediatrik OSAS kohortunda trombosit aktivasyonu ile belirgin bir ilişki olmadığını düşündürmektedir. Bununla birlikte, OSAS grubunda hemoglobin düzeyleri anlamlı derecede daha düşük; trombosit sayısı, lökosit sayısı, nötrofil sayısı ve NLR ise anlamlı derecede daha yüksek bulundu (p < 0.05). Bu sonuçlar artmış inflamatuvar yanıtı işaret etmektedir. ROC analizi, NLR’ın sınırlı tanısal değere sahip olduğunu ve 0.644 AUC ile en uygun kesim değerinin 0.977 olduğunu gösterdi. Sonuç: MPV ve PLR anlamlı farklılık göstermese de, yükselmiş NLR değeri adenoid hipertrofisine bağlı OSAS’lı çocuklarda artmış sistemik inflamasyonu düşündürmektedir. Tanısal performansı sınırlı olsa da NLR yardımcı bir inflamasyon belirteci olarak değerlendirilebilir. Bu parametrelerin pediatrik hava yolu obstrüksiyonundaki tanısal ve prognostik rollerini daha net belirleyebilmek için geniş ölçekli, prospektif çalışmalara ihtiyaç vardır.
