Abstract

Aim: To assess the utility of serum C-reactive protein (CRP) and Procalcitonin (PCT) as a screening method for occult bacterial infection (OBI) in 3-36 month old children. Materials and Methods: Febrile children, who were admitted to emergency department with ages ranging from 3 to 36 months, temperatures > 38.3°C, and clinically undetectable source of fever, were enrolled in this study. Sex, age, degree of fever, Yale Observation Scale (YOS) score, antibiotic treatment and hospitalization were recorded at the time of the initial evaluation. Routine urine analysis, white blood cell count (WBC) count, CRP and PCT determination tests were performed at the initial evaluation. Viral serology was done and patients having specific IgM positivity during the acute phase and/or a four-fold increase in specific IgG titer during convalescence phase were considered to be positive. A chest radiograph, blood culture and urine cultures were taken from all patients. The patients were divided into two groups: OBI group and viral infection group. These two groups were compared for each predictor. Results: There were 10 patients with OBI, six with urinary tract infection two with pneumonia, one with bacterial meningitis and one with bacteremia and 16 patients with viral infection, (five Adenovirus, five Respiratory syncytial virus, four Enterovirus, one Parainfluenza type 1, one Epstein- Barr virus. Regarding the CRP values, there was no statistical difference between OBI and viral infection groups (respectively, median 44.84 mg/L and 23.3 mg/L, p=0.097), but PCT values were significantly higher in OBI group (respectively, median 2.38 ng/mL and 0.28 ng/mL, p=0.014). Conclusion: This study showed that PCT is superior than CRP in detecting OBI and could be used for screening purposes in pediatric emergency departments while elevated levels might be found in some viral infections.

Özet

Amaç: Üç–36 ay arası gizli bakteriyel enfeksiyon riski taşıyan hastaların saptanmasında C-reaktif proteinin (CRP) ve Prokalsitoninin (PCT) kullanılabilirliğini saptamak. Gereç ve Yöntem: Yaşları 3-36 ay arası olan, 38.3oC üzerinde ateş yüksekliği şikayeti ile acil servise başvuran ve ateş odağı saptanamayan hastalar çalışmaya alındı. Başvuru anında, cinsiyetleri, yaşları, ateş yüksekliğinin derecesi, Yale Gözlem Ölçeği (YGÖ) skoru, hastaneye yatma ve antibiyotik başlanma durumları kaydedildi. Başvuru anında, rutin idrar analizi, beyaz küre sayıları, CRP ve PCT’nin düzeylerinin ölçümü için testler yapıldı. Viral serolojik inceleme yapıldı ve akut faz dönemindeki spesifik IgM pozitifliği ve/veya konvalasan fazda spesifik IgG düzeylerinde 4 katlık artış pozitif olarak kabul edildi. Tüm hastalardan kan kültürü, idrar kültürü yapıldı ve akciğer grafileri çekildi. Hastalar gizli bakteriyal enfeksiyon ve viral enfeksiyon grubu olmak üzere ikiye ayrıldı. İki grup verileri her bir belirleyici açısından karşılaştırıldı. Bulgular: Gizli bakteriyel enfeksiyonlu 10 hastada, altı idrar yolu enfeksiyonu, iki bronkopnömoni, bir menenjit, bir bakteriyemili hasta saptanırken, viral enfeksiyon saptanan 16 hastada, beş Adenovirus, beş Respiratory syncytial virus, dört Enterovirus, bir Parainfluenza Tip1 ve bir Epstein-Barr virus enfeksiyonlu hasta saptandı. Gizli bakteriyel enfeksiyon grubu, viral enfeksiyon grubu ile CRP değerleri açısından karşılaştırıldığında istatistiksel olarak anlamlı fark saptanmazken (sırasıyla, ortanca 44.84 mg/L ve 23.3 mg/L, p=0.097), PCT değerleri istatistiksel olarak anlamlı saptandı (sırasıyla, ortanca 2.38 ng/mL, 0.28 ng/mL, p=0.014). Sonuç: Bu çalışma, çocuk acil bölümlerinde PCT’nin gizli bakteriyel enfeksiyonları saptamada CRP’ye göre daha üstün bir belirleyici olduğunu ve tarama amaçlı kullanılabileceğini, ancak bazı viral enfeksiyonlarda yüksek saptanabileceğini göstermiştir.
