Down sendromlu çocuklarda hematolojik parametrelerin değerlendirilmesi

Amaç: Konjenital hematolojik bozukluklar Down sendromunda (DS) sıklıkla gözlenmektedir. Bu çalışmada Down sendromlu hastalarda nötrofil/lenfosit oranı, trombosit/lenfosit oranı ve eozinofil/monosit oranı gibi periferik kan kaynaklı inflamasyon biyobelirteçlerini araştırmayı amaçladık. Gereç ve yöntem: Çalışmaya karyotipik olarak tanısı konulan DS’li 98 hasta ve 103 sağlıklı kontrol dahil edildi. Hasta ve kontroller üç yaş grubuna ayrıldı: 0-2 yaş (34 hasta, 34 kontrol), 2-6 yaş (32 hasta, 33 kontrol) ve 6-18 yaş (32 hasta, 36 kontrol). Haziran 2010 ile Aralık 2021tarihleri arasındaki demografik, klinik ve laboratuvar verileri, Çocuk Alerji ve İmmünoloji bölümündeki dosya kayıtlarından yazıldı. Bulgular: Lenfosit, eozinofil ve EMR, DS'li çocuklarda grup 2 (2-6 yaş) ve grup 3'te (>6 yaş) kontrollere göre anlamlı derecede düşük bulundu. Grup 2 ve grup 3'te DS'li çocuklarda PLO daha yüksek bulundu. Grup 1'de (

Evaluation of hematologic parameters in children with Down syndrome

Objective: Congenital hematological disorders are frequently observed in Down syndrome (DS). In this study, we aimed to investigate peripheral blood-derived inflammation biomarkers such as neutrophil/lymphocyte ratio, platelet/lymphocyte ratio, and eosinophil/monocyte ratio in patients with Down syndrome. Material and Methods: Ninety-eight patients with karyotypically ascertained DS and 103 healthy controls were included. All subjects were divided into three age groups: 0-2 years (34 patients, 34 controls), 2-6 years (32 patients, 33 controls), and >6 years (32 patients, 36 controls). Demographic, clinical, and laboratory data between June 2010 and December 2021 were written from the file records from the pediatric allergy and immunology department. Results: Lymphocyte, eosinophil, and EMR were found to be significantly lower in children with DS compared to controls in group 2 (2-6 years) and group 3 (>6 years). PLR was found to be higher in children with DS in group 2 and group 3. There was no statistically significant difference between DS and controls in group 1 (6 years), there was a statistically significant difference between DS and controls in terms of lymphocyte, eosinophil, PLR, and EMR variables (P>0.05). Conclusion: We found significant differences among lymphocyte, eosinophil, PLR, and EMR in patients with DS. As a result, these parameters should be evaluated carefully for clinical outcomes.
