Abstract

Introduction: Sepsis is a clinical picture closely associated with mortality that affects a large number of patients worldwide every year. This condition, which is frequently associated with infection, can also develop due to noninfectious causes such as burns. Sepsis is also associated with disseminated intravascular coagulation (DIC). Fibrinogen is a coagulation factor secreted from the liver. Liver failure, cardiac diseases, malignancies and some chemotherapy drugs may affect fibrinogen levels. Especially fibrinogen tends to decrease due to sepsis. This is of critical importance especially in sepsis-associated DIC. Material and method: In this retrospective study of 80 patients aged 18-90 years who were hospitalized in the anesthesiology and reanimation intensive care unit, fibrinogen, platelet, WBC, INR, aPTT, CRP, procalcitonin, SOFA and ISTH scores measured on days 0 and 3 were collected and their relationships with mortality were compared. Statistical analyses were performed using SPSS 22.0 for. Patients were divided into 3 groups according to fibrinogen trend. Results: According to statistical analysis, SOFA and ISTH scores were found to be high in the group with low fibrinogen level (p:0,032 - p:0,005 for SOFA, p:0,026 - p:0,038 for ISTH score, respectively), and WBC, Platelet, Procalcitonin and D-Dimer were found to be high among laboratory parameters (p: 0.013 - p:0.020 for WBC, p:0.030 for Platelet, p:0.009 - p:0.008 for Procalcitonin, p:0.001 - p:0.008 for D-Dimer, respectively) and mortality was higher in the group with decreased fibrinogen level compared to the other groups (p<0.001). Discussion: In sepsis and DIC, it is critical to rapidly diagnose, initiate treatment and predict mortality. Although many scoring systems have been developed for this purpose, SOFA is the most commonly used scoring system for sepsis and ISTH for DIC. According to our results, SOFA and ISTH scoring systems as well as decreased fibrinogen level can be used to predict mortality. Decreased fibrinogen level in sepsis can be used as a predictor of mortality.

Özet

Giriş: Sepsis dünya genelinde her yıl çok sayıda hastanın etkilendiği mortaliteyle yakından ilişkisi olan klinik bir tablodur. Sıklıkla enfeksiyonla ilişkili olan bu durum yanık gibi nonenfeksiyöz nedenlere bağlı olarak da gelişebilmektedir. Sepsis aynı zamanda dissemine intravasküler koagülasyon (DİK) ile karşılıklı ilişkisi bulunan bir durumdur. Fibrinojen karaciğerden salgılanan bir koagülasyon faktörüdür. Karaciğer yetmezliği, kardiyak hastalıklar, maligniteler ve bazı kemoterapi ilaçları fibrinojen seviyesini etkileyebilmektedir. Özellikle fibrinojen sepsise bağlı olarak azalma eğilimindedir. Bu durum özellikle sepsise bağlı gelişen DİK tablosunda kritik bir öneme sahiptir. Materyal metot: Kanuni Sultan Süleyman hastanesi anesteziyoloji ve reanimasyon yoğun bakım ünitesinde yatmış olan 18-90 yaş arasındaki 80 hastada retrospektif olarak yapılan bu çalışmada 0.ve 3.günlerde ölçülmüş olan fibrinojen, platelet, WBC, INR, aPTT, CRP, prokalsitonin değerleri ile birlikte SOFA ve ISTH skorları toplanmış ve mortalite ile olan ilişkileri karşılaştırılmıştır. İstatistiksel analizler SPSS 22.0 for kullanılarak yapılmıştır. Fibrinojen trendine göre hastalar 3 gruba ayrılmıştır. Bulgular: İstatistiksel analize göre fibrinojen seviyesi düşük olan grupta SOFA ve ISTH skorları yüksek bulunmuş (SOFA için sırasıyla p:0,032 – p:0,005, ISTH skoru için sırasıyla p:0,026 – p:0,038), laboratuvar parametrelerinden WBC, Platelet, Prokalsitonin ve D-Dimer yüksek bulunmuştur (WBC için sırasıyla p:0,013 – p:0,020, Platelet için p:0,030, Prokalsitonin için sırasıyla p:0,009 – p:0,008, D-Dimer için sırasıyla p:0,001 – p:0,008) ve mortalite için fibrinojen seviyesi azalmış olan grupta mortalite diğer gruplara kıyasla daha yüksek bulunmuştur (p<0,001). Tartışma: Sepsiste ve DİK’te hızlıca tanıyı koyabilmek, tedaviyi başlayabilmek ve mortaliteyi öngörebilmek kritik öneme sahiptir. Bu amaçla çok sayıda skorlama sistemi geliştirilmiş olmakla sepsis için günümüzde en sık kullanılan skorlama sistemi SOFA iken DİK için ISTH skorlamalarıdır. Bizim elde ettiğimiz sonuçlara göre SOFA ve ISTH skorlama sistemleri ile birlikte azalmış fibrinojen seviyesi de mortaliteyi ön görmek amacıyla kullanılabilir. Sepsiste fibrinojen seviyesinde meydana gelen azalma mortalite açısından bir prediktör olarak kullanılabilir.
