Abstract

Objective: Determination of the factors associated with the intensive care unit (ICU) prognosis and mortality has important role in the clinical follow-up of the patients. Definition of novel biomarkers, beside older biomarkers available for evaluation of the outcome of these patients has been proposed. Platelet-activating factor acetylhydrolase (PAF-AH) is an enzyme that inactivates the platelet-activating factor. A reduction in the level of the PAF-AH has been demonstrated during systemic inflammation and multiple organ failure. This research aims to determine whether measurement of PAF-AH enzyme activity in ICUs can be used as a prognostic indicator like conventional biomarkers.Methods: Eighty five adult patients have been included. Following data have been recorded: preliminary C-reactive protein (CRP), lactate, albumin and PAF-AH values, APACHE II scores and discharge forms from ICU. Patients were divided in two groups with respect to APACHE II values: Group 1 and Group 2 (>=20).Results: Observed mortality was 51.2%. In the APACHE II Group 2 patients, the values of CRP (p=0.001) and lactate (p=0.040) were significanty high, and the values of PAF-AH (p=0.008) and albumin (p=0.001) were significantly low. A statistically significant difference was found between PAF-AH values of exitus and alive patients (p=0.001). According to ROC analysis, the sensitivity and specificity of predicting mortality was 70.5% and 70.7%for CRP, 63.6% and 70.7% for lactate, 90.2% and 61.4% foralbumin and 63.6% and 70% PAF-AH, respectively.Conclusion: Our study demonstrated that, in predictingthe ICU mortality risk, sensitivity of the PAF-AH is similarto the sensitivity of the lactate, and specificity of thePAF-AH is better than that of the albumin. According to ourresults, PAF-AH can be included in the novel biomarkers.

Özet

Amaç: Yoğun Bakım ünitelerinde mortalite ve prognozu etkileyen faktörlerin belirlenmesi, hastanın klinik durumunun takibi için faydalıdır. Bu amaçla rutin kullanılan diagnostik belirteçlerin yanı sıra yeni belirteçlerin kullanımı da gündemdedir. Platelet aktive edici faktör asetil hidrolaz (PAF-AH), PAF'ı inaktive eden enzimdir. Sistemik enflamasyonda ve multipl organ yetmezliklerinde dolaşımdaki PAF-AH düzeylerinde azalma gösterilmiştir. Bu araştırmada PAF-AH enzim aktivitesi ölçümünün Yoğun Bakım ünitelerinde prognoz göstergesi olarak kullanılıp kullanılamayacağını araştırdık.Metod: Seksen beş erişkin hasta çalışmaya dahil edildi. Hastaların Yoğun Bakım'a kabuldeki C-reaktif protein (CRP), laktat, albümin ve PAF-AH değerleri ile APACHE II skorları ve yoğun bakımdan çıkış biçimleri kaydedildi. Hastalar APACHE II değerlerine göre iki gruba ayrıldılar; Grup 1 ve Grup 2 (>=20).Bulgular: Yoğun Bakım Ünitemizde gözlenen mortalite oranı %51.2 idi. APACHE II 2. grupta CRP (p=0.001) ve laktat (p=0.040) seviyeleri anlamlı olarak yüksek iken, PAF-AH (p=0.008) ve albümin (p=0.001) değerleri düşüktü. PAF-AH düzeyleri açısından ölen hastalarla yaşayan gruplar arasında anlamlı bir farklılık tespit edildi (P=0.001). Yapılan ROC analizine göre, CRP'nin mortaliteyi göstermedeki duyarlılığı %70.5, özgüllüğü %70.7, laktatın duyarlılığı %63.6, özgüllüğü %70.7, albüminin duyarlılığı %90.2, özgüllüğü %61.4, PAF-AH'ın duyarlılık ve özgüllüğü ise sırasıyla %63.6 ve %70 idi.Sonuç: Çalışmamızda PAF-AH'ın Yoğun Bakım mortalite riskini belirlemede laktat ile eşit duyarlılıkta olduğu, özgüllüğünün ise albüminden daha yüksek olduğu tespit edilmiştir. PAF-AH, Yoğun Bakım hastalarında prognozun değerlendirilmesi amacıyla kullanılabilecek yeni bir biyo belirteçtir.
