Serum interleukin-6 levels in differential diagnosis of sepsis and transient tachypnea of newborn

Amaç: Bu çalışmanın amacı yenidoğanlarda serum interlökin 6 düzeyinin bakteriyel sepsis ve yenidoğanın geçici takipnesinin ayrımında rolünün araştırılmasıdır. Hastalar ve Yöntemler: Solunum sıkıntısı olan ve gestasyonel yaşı 35 haftadan büyük olan 58 yenidoğan çalışmaya alındı. Hastalar, kanıtlanmış veya klinik sepsisi olanlar ve yenidoğanın geçici takipnesi olanlar olmak üzere iki gruba ayrıldı. Klinik bulgular beyaz küre sayısı, C reaktif protein, serum IL-6 düzeyi, periferik yaymada immature nötrofil sayısının toplam nötrofil sayısına oranı kaydedilerek gruplar arasında karşılaştırıldı. Bulgular: Her iki grupta da serum CRP ve IL-6 düzeyleri normal limitlerden yüksek bulunmasına rağmen iki grup arasında fark yoktu. Solunum sıkıntısının süresi ve I/T oranı yenidoğanın geçici takipnesi olan grupta belirgin olarak fazla bulundu. Sonuç: IL-6 ve I/T oranı solunum sıkıntısı olan sepsisli yenidoğanların erken tanısı konusunda katkıda bulunurken IL-6 düzeyi tek başına yenidoğanlarda sepsis ve yenidoğanın geçici takipnesinde kullanılamaz.

Yenidoğanlarda sepsis ve yenidoğanın geçici takipnesinin ayırıcı tanısında serum interlökin-6 düzeyleri

Objectives: The aim of this study was to evaluate the role of serum interleukin-6 (IL-6) levels in the differentiation of neonatal bacterial sepsis and TTN. Patients and Methods: The hospital records of 58 newborns with respiratory distress that were above 35 weeks of gestational age were investigated. Patients were divided into two groups. The infection group consisted of patients with proven sepsis and clinical sepsis and the remaining one was TTN group. Clinical findings and white blood cell count, serum C-reactive protein (CRP), IL-6 levels and the ratio of immature neutrophils to total neutrophils count (I/T) were recorded and were compared between the two groups. Results: Serum CRP and IL-6 levels were found higher than normal limits in both of the groups. However there was no significant difference between them. Duration of respiratory distress was longer and I/T ratio was significantly higher in the infection group than TTN group. Conclusion: I/T ratio and IL-6 may contribute to the early diagnosis of sepsis with respiratory symptoms in newborn but IL-6 alone can not distinguish TTN and sepsis.
