GİRİŞ ve AMAÇ: Human paraoksonaz-1 (PON1), oksidatif strese karşı çalışan endojen antioksidan moleküllerden biridir. Bu çalışmada akut bronşiolitli çocuklarda serum PON1 aktivitesini araştırmayı amaçladık.

YÖNTEM ve GEREÇLER: Akut bronşiyolitli 3-21 aylık 29 çocuk ile yaş uyumlu 35 sağlıklı kontrol çalışmaya dahil edildi. Bronşiolit hastaları hafif (% 65) ve orta (% 35) olarak sınıflandırıldı. Akut bronşiolitli hastalar ile kontrol grubu arasında PON1'in paraoksonaz ve arilesteraz aktiviteleri karşılaştırıldı.

BULGULAR: Akut bronşiyolitli çocukların paraoksonaz aktivitesi sağlıklı kontrollere göre daha düşüktü, ancak fark anlamlı değildi (127.53 ± 64.17 U / L'ye karşı 153.95 ± 74.40 U / L) (p = 0.13). Hafif ve orta derecede bronşiyolitli çocuklarda arilesteraz aktivitesi kontrol grubuna göre anlamlı olarak daha azdı (142.43 ± 56.60 kU / L ve 103.05 ± 26.03 kU / L'ye karşılık 201.09 ± 57.26 kU / L) (p <0.001).

TARTIŞMA ve SONUÇ: Akut bronşiolitli çocuklarda serum PON1 aktivitesi kontrol grubuna göre daha düşüktü. Antioksidan kapasitenin arttırılması, viral kaynaklı akciğer hastalığında etkili bir tedavi aracı olabilir

Human Paraoxonase-1 Activity in Children with Acute Bronchiolitis

Öz

INTRODUCTION: Human paraoxonase-1 (PON1) is one of the endogenous antioxidant molecules working against oxidative stress. We aimed to investigate serum PON1 activity in children with acute bronchiolitis.

MATERIALS and METHODS: A total of 29 children aged between 3-21 months with acute bronchiolitis and 35 age-matched healthy controls were included in the study. Bronchiolitis patients were further classified as mild (65%) and moderate (35%). Paraoxonase and arylesterase activities of PON1 were compared between patients with acute bronchiolitis and the control group.

RESULTS: Paraoxonase activity of children with acute bronchiolitis was lower than healthy controls but the difference was not significant (127.53 ± 64.17 U/L versus 153.95 ± 74.40 U/L) (p=0.13). Arylesterase activity was significantly decreased in children with mild and moderate bronchiolitis in comparison to the control group (142.43± 56.60 kU/L and 103.70± 26.03 kU/L versus 201.09± 57.26 kU/L) (p<0.001).

CONCLUSIONS: Serum PON1 activity was lower in children with acute bronchiolitis compared to controls. Increasing antioxidant capacity may be an effective means of therapy in viral induced lung disease.
