Abstract

INTRODUCTION: Pulmonary Function Tests (PFT) are important and frequently used for the preoperative evaluation of patients that will undergo cardiothoracic surgery and PFT are routinely required by anesthesiologists and surgical teams. Neutrophil Lymphocyte Ratio (NLR) is a biomarker recently reported by several studies to be associated with many diseases, and Platelet Lymphocyte Ratio and systemic immune inflammation index similarly. The aim of this study is to evaluate the presence of any correlation between PFT and theese ratios in patients without pulmonary disease or risk factors due to undergo CABG. METHODS: The retrospective study was conducted at our hospital and performed by reviewing data of patients undergoing CABG between January 2014 and August 2015. Demographical features, echocardiological results, complete blood count results, ratios of NLR, PLR, SII and PFT results were evaluated in patients undergoing CABG. RESULTS: Data of 61 patients were analyzed. A negative linear correlation was found between NLR and FEV1/FVC and NLR and MEF 75-25 % (p<0.01). ROC analysis was used to determine the cut off value for NLR when MMEF 75-25 < 80% and FEV1/FVC<80%. Cut off value of 2.105 was chosen for NLR with a sensitivity of 67.74% and specificity of 73.33% for FEV1/FVC <80% and sensitivity of 68.75% and specificity of 75.86% for MMEF75-25 <80%. DISCUSSION AND CONCLUSION: In patients without respiratory disease, due to undergo CABG, NLR shows an inverse correlation with PFT results. Our study is the first to put forth simple biomarkers calculated from CBC that can predict PFT

Özet

GİRİŞ ve AMAÇ: Pulmoner Fonksiyon Testleri (PFT) kardiyotorasik cerrahi öncesi preoperatif değerlendirmede sık başvurulan önemli bir testtir. Nötrofil lenfosit oranı ise birçok çalışmaya konu olmuş, bir çok hastalık ile ilişkisi olduğu ortaya konmuş bir biyomarkerdır. Benzer şekilde platellet lenfosit oranı (PLR) ve sistemik immun inflamatuar indexte çalışmalara konu olmaktadır. Bu çalışmada amacımız; CABG hastalarında yapılan PFT ile bu oranlar arasında bir ilişki olup olmadığını araştırmaktır. YÖNTEM ve GEREÇLER: Bu retrospektif çalışmada Ocak 2014 ile Austos 2015 tarihleri arasında merkezimizde CABG uygulanan hastaların verilerini değerlendirilmiştir. CABG uygulanan hastaların demografik özellikler, kan sayımları, NLR, PLR, SIII ve PFT sonuçları kayıt altına alınarak değerlendirilmiştir. BULGULAR: CABG uygulanan 61 hastanın verileri değerlendirildi. NLRile FEV1/FVC ve NLR ile MMEF75-25 arasında negatif yöne bir korelasyon tespit edildi (p<0.01).NLR için MMEF 75-25 < %80 ve FEV1/FVC<%80 olduğunda cut-off değeri belirlemek için ROC analizi yapıldı ve cut off değeri 2.105 olarak belirlendi (Sensitivity %67 ve specificity % 73) TARTIŞMA ve SONUÇ: Respiratuar hastalık öyküsü olmayan ve CABG uygulanacak hastalarda NLR pılmoner fonksiyon testleri ine ters yönlü bir korelasyon göstermektedir. Çalışmamız, tam kan sayımından türetilen basit bir biyomarker olan NLR ile pulmoner fonksiyon testleri ilişkisini ortaya koyan ilk çalışmadır.
