GNB group was further divided intoEnterobacteriaceae bacteremia (GNEB) and Non-Enterobacteriaceae (GNNEB).Results: Procalcitonin levels of GNB and GPB groups were significantly different (P= 0.0001).Procalcitonin and CRP levels of GNEB and GNNEB groups were also significantly different(P=0.015 and P= 0.003, respectively).Conclusion: Our findings suggest that procalcitonin levels may be discriminative between GNBand GPB groups and levels >4.055 ng/mL may be evidence of GNB.

Abstract

Objective: Patients with sepsis constitute a significant proportion of critically ill patients. Althoughoutcomes have significantly improved in the last decade, mortality still remains high 25-30% and40-50% when shock is present. Procalcitonin has been studied in sepsis for diagnosis, andguidance of antibiotic therapy. We investigated the levels of C-reactive protein (CRP) andprocalcitonin in patients with bacteremia seen in various departments of the hospital and toevaluate the possible discriminative role of procalcitonin in differentiating bacterial etiology ofinfection.Materials and methods: Serum procalcitonin and CRP levels of patients with Gram negative andpositive bacteremia were recorded retrospectively. CRP and procalcitonin levels of 407consecutive patients with 636 positive blood cultures were included in the study. The blood cultureswere first grouped as Gram-positive bacteremia (GPB) and Gram-negative bacteremia (GNB). 316(49.7%) of 636 positive blood culture were in GPB group. GNB group was further divided intoEnterobacteriaceae bacteremia (GNEB) and Non-Enterobacteriaceae (GNNEB).Results: Procalcitonin levels of GNB and GPB groups were significantly different (P= 0.0001).Procalcitonin and CRP levels of GNEB and GNNEB groups were also significantly different(P=0.015 and P= 0.003, respectively).Conclusion: Our findings suggest that procalcitonin levels may be discriminative between GNBand GPB groups and levels >4.055 ng/mL may be evidence of GNB.

Özet

Amaç: Sepsis hastaları, kritik durumdaki hastaların önemli bir bölümünü oluşturmaktadır. Sonuçlar bakımından son on yılda önemli ölçüde gelişme kaydedilse de, mortalite oranı halen %25-30 düzeylerinde seyretmekte ve şok eşliğinde %40-50’ye kadar yükselebilmektedir. Prokalsitonin, tanı amacıyla ve antibiyotik tedavisinin yönetimi bakımından sepsiste üzerinde çalışılmış bir peptiddir. Çalışmada bakteriyemi hastalarında hastanemizin çeşitli bölümlerinde C-reaktiv protein (CRP) ve prokalsitonin düzeylerini araştırdık ve prokalsitoninin bakteriyel enfeksiyon etiyolojisini ayırt etme bakımından ne tür bir rolü olabileceğini değerlendirildi. Gereç ve Yöntem: Gram negatif ve pozitif bakteriyemisi olan hastaların serum prokalsitonin ve CRP düzeyleri, retrospektif olarak kayıt altına alındı. Çalışmaya, 636 pozitif kan kültürü olan 407 hastanın CRP ve prokalsitonin düzeyleri dahil edildi. Kan kültürlerine göre bakteriyemik ataklar, önce Gram-pozitif bakteriyemi (GPB) ve Gram-negatif bakteriyemi (GNB) olarak gruplandırıldı. GPB grubunda 636 kültür arasından 316 (%49.7) pozitif kan kültürü tespit edildi. GNB grubu ayrıca Enterobacteriaceae bakteriyemi (GNEB) ve Non-Enterobacteriaceae (GNNEB) olarak ikiye ayrıldı. Bulgular: GNB ve GPB gruplarının prokalsitonin düzeyleri anlamlı olarak farklıydı (P= 0.0001). GNEB ve GNNEB gruplarının prokalsitonin ve CRP düzeyleri de anlamlı şekilde farklıydı (sırasıyla P= 0.015 ve P= 0.003). Sonuç: Bulgularımız, prokalsitonin düzeylerinin, GNB ve GPB grupları arasında ayırt edici olabileceğini ve 4.055 ng/mL’nin üzerindeki düzeylerin GNB'nin kanıtı olabileceğini düşündürmektedir.
