Abstract

This study was aimed to investigate the prognostic value of tumor necrosis factor-alpha (TNF-a), interleukin-10 (IL-10), leptin and C-reactive protein (CRP) levels in newborn sepsis. A total of 57 new-boms with nosocomial sepsis and 30 healthy newborns were included to the study. Serum TNF-a, IL-10, leptin (Biosource, Belgium) and CRP (Dade Behring, Germany) levels were investigated by ELISA methodology before the initiation of the therapy (day 0) and on the third and fifth days of therapy. Initial leptin levels were found to be high in the control group (p= 0.00) and CRP levels were found to be high in the patient group (p= 0.00). No significant difference was detected for IL-10 and TNF-a levels (p> 0.05). CRP levels were significantly higher in the patient group than the controls on the third day of the therapy (p= 0.001), however, no significant difference was detected for the other parameters (p> 0.05). On the fifth day of the therapy CRP (p= 0.023) and leptin (p= 0.00) levels were significantly high in the patient group and TNF-a in the control group (p= 0.00) while no significant difference was observed for IL-10 levels (p> 0.05). Mortality rate was 24.5%. When the mean TNF-a, IL-10, leptin and CRP levels on the 0th, 3rd and 5th days were analysed for alive (n= 43) and dead (n=14) newborns with sepsis, it was observed that TNF-a, IL-10 and CRP levels were related with poor prognosis (p< 0.05). The ROC analysis performed for the determination of the prognostic performance of TNF-a and IL-10 revealed that these parameters had predictive value about mortality when their levels were above certain cut-off values (on the 5th day of therapy for IL-10 > 1.8 ng/ml and for TNF-a > 21.1 ng/ml). It can be concluded that besides routine laboratory parameters, serum TNF-a and IL-10 levels at the initiation of therapy and afterwards may help to predict prognosis and guide treatment in newborns with sepsis.

Özet

Bu çalışmada, sepsisli yenidoğanlarda tümör nekrozis faktör-alfa (TNF-a), interlökin-10 (IL-10), lep-tin ve C-reaktif protein (CRP) düzeylerinin prognostik değerinin araştırılması amaçlanmıştır. Çalışmaya, nozokomiyal sepsisli 57 yenidoğan ile kontrol grubu olarak 30 sağlıklı yenidoğan dahil edilmiş; serum TNF-a, IL-10, leptin (Biosource, Belçika) ve CRP (Dade Behring, Almanya) düzeyleri tedavi başlamadan önce (0. gün) ve tedavinin üçüncü ve beşinci günlerinde ticari ELISA kitleriyle araştırılmıştır. Çalışmada, başlangıç leptin düzeyleri kontrol grubunda (p= 0.00), CRP düzeyleri ise hasta grubunda (p= 0.00) anlamlı düzeyde yüksek bulunmuş; TNF-a ve IL-10 düzeylerinde anlamlı bir fark saptanmamıştır (p> 0.05). Tedavinin üçüncü gününde, sepsisli yenidoğanlarda CRP düzeyleri kontrollere göre anlamlı olarak yüksek bulunmuş (p= 0.001); diğer parametreler için gruplar arasında önemli bir fark saptanmamıştır (p> 0.05). Tedavinin beşinci gününde ise CRP (p= 0.023) ve leptin (p= 0.00) düzeylerinin hasta grubunda; TNF-a düzeyinin ise kontrollerde (p= 0.00) anlamlı olarak yüksek olduğu izlenmiş, IL-10 düzeyindeki fark anlamlı bulunmamıştır (p> 0.05). Çalışmamızda mortalite oranı %24.5 olarak belirlenmiş; yaşayan (n= 43) ve ölen (n= 14) sepsisli yenidoğanların 0, 3 ve 5. günlerdeki ortalama serum TNF-a, IL-10, leptin ve CRP düzeyleri karşılaştırıldığında; leptin düzeyleri hariç (p> 0.05), TNF-a, IL-10 ve CRP değerlerinin kötü prog-nozla ilişkili olduğu izlenmiştir (p 1.8 ng/mL, TNF-a için > 21.1 ng/mL) mortaliteyi tahmin etmede ayırıcı özellikte olduğu gözlenmiştir. Sonuç olarak; sepsisli yenidoğanlarda rutin laboratuvar parametrelerinin yanında, tedavinin başlangıcında ve tedavi sırasında serum TNF-a ve IL-10 düzeylerinin belirlenmesinin, hastalığın prognozunda ve uygun tedavi değişikliklerinin yapılmasında yol gösterici olacağı düşünülmüştür.
