Abstract

Amaç: Bakteriyel enfeksiyonların erken teşhisi, tedavinin planlanmasında çok önemlidir. Bu nedenle, bakteriyel enfeksiyonun yanı sıra bakterilerin gram boyanma özelliğinin belirlenmesi de önem arzeder. Akut bakteriyel enfeksiyon, nötrofillerde morfolojik değişikliklere yol açar. Bu çalışmada, bakteriyel enfeksiyonların hızlı tanısı ile gram pozitif ve gram negatif bakterilerin neden olduğu enfeksiyonları ayırt etmek için nötrofil hacim, iletkenlik ve ışık saçılımı (VCS) parametrelerinin potansiyel bir gösterge olarak kullanımı araştırıldı.
Gereç ve Yöntemler: Çalışmaya, üriner sistem enfeksiyonu, pnömoni, yara yeri enfeksiyonu ve sepsisi olan hastalar dahil edildi. Kontrol grubu, bakteriyel enfeksiyonu saptanmamış hastalardan oluşturuldu. Hastalarının kan örnekleri beyaz kan hücresi ve nötrofil sayımı için incelendi; nötrofil VCS parametreleri, bir Coulter Analizörü kullanılarak belirlendi. Üreyen bakteri türlerini tespit etmek için VITEK 2 Kompakt Sistemi kullanıldı.
Bulgular: Çalışmada, çeşitli kliniklerden tam kan sayımı için laboratuvarımıza gönderilen 472 hastanın kan örneği analiz edildi. Bu hastaların 370’inin bakteriyolojik kültürlerinde anlamlı üremesi mevcut iken, 102’sinin anlamlı bakteri üremesi yoktu. Bakteriyel enfeksiyonu saptamada, medyan nötrofil hacmi (MNV) ve medyan nötrofil iletkenliğinin (MNC) özgüllükleri sırasıyla %96 ve %99 olarak bulundu. Ayrıca, medyan nötrofil ışık saçılımının (MNS), gram-negatif bakteri üremesi saptananlarda, gram-pozitif bakteri üremesi saptananlara göre daha yüksek olduğu görüldü.
Sonuç: Bakteriyel enfeksiyonları belirlemek ve gram-pozitif ve gram-negatif bakteriyel enfeksiyon varlığını birbirinden ayırt etmek için nötrofil VCS parametrelerinin kullanımı, etkin ve zaman kazandırıcı bir yöntemdir.

Abstract

Aim: Early diagnosis of bacterial infections is crucial in planning treatment. Thus, it is important to determine the gram staining property of bacteria as well as the presence of bacterial infection. The acute bacterial infection leads to morphological changes in neutrophils. In this study, we investigated the use of neutrophil volume, conductivity and light-scattering (VCS) parameters as potential indicators for rapid diagnosis of bacterial infections, and to distinguish infections caused by gram-positive and gram-negative bacteria.
Material and Methods: Patients with urinary tract infections, pneumonia, wound site infections and sepsis were included. The control group comprised patients without bacterial infections. The blood samples of the patients were examined for white blood cell and neutrophil counts; neutrophil VCS parameters were determined using a Coulter Analyzer. The VITEK 2 Compact System was used to detect microbial growth.
Results: The blood sample data of 472 patients sent to our laboratory for Complete Blood Count analyses from various clinics were analyzed in this study. A total of 370 samples showed significant growth in their bacteriological culturing, whereas the remaining 102 samples showed no growth. For the detection of bacterial growth, the specificities of median neutrophil volume (MNV) and median neutrophil conductivity (MNC) were found to be 96% and 99%, respectively. In addition, median neutrophil light scattering (MNS) was higher in the gram-negative bacterial group than in the gram-positive bacterial group.
Conclusion: The use of neutrophil VCS parameters is an effective and time-saving method to identify bacterial infections and distinguish between gram-positive and gram-negative bacterial infections.
