Abstract

Objectives: The prognostic importance of red cell distribution width (RDW) and neutrophil/lymphocyte ratio (NLR) in cardio- vascular diseases has been shown. Ascending aortic dilata- tion (AAD) is a common cardiovascular disease and is associ- ated with aortic wall inflammation and cystic degeneration. In this study, we aimed to investigate the relationship between serum levels of RDW, NLR and the presence of AAD. Study design: Two-hundred consecutive patients with AAD diagnosed by transthoracic echocardiography were pro- spectively recruited and were compared to 170 age-gender- matched subjects with normal aortic diameters. Complete blood counts (CBCs) were analyzed for hemoglobin, RDW and NLR counts, as well as mean corpuscular volume (MCV). If possible, results of CBC tests within the previous two years were also included and the averages were used. Results: RDW [median 13.9, interquartile range (IQR) 1.40 vs. median 13.3, IQR 1.05%, p=0.01], NLR (median 2.04, IQR 1.09 vs. median 1.78, IQR 0.90, p=0.01) and high-sensitive C- reactive protein (hs-CRP) (median 0.60, IQR 0.80 vs. median 0.44, IQR 0.68 mg/L, p=0.01) levels were significantly higher in the AAD group compared to the control group. In univariate correlation analysis, ascending aortic diameters were corre- lated with RDW levels (r=0.31, p=0.01), NLR levels (r=0.15, p=0.01) and hs-CRP levels (r=0.12, p=0.03). In multivariate logistic regression analysis, increased levels of RDW and hs- CRP remained as the independent correlates of AAD in the study population. Receiver operating characteristic (ROC) curve analysis revealed that a RDW measurement higher than >13.8% predicted AAD with a sensitivity of 49.5% and a speci- ficity of 82.8% (area under the curve [AUC] 0.681, p=0.01). Conclusion: In patients with AAD, RDW and hs-CRP levels are increased, which may indicate the role of inflammation in the pathogenesis of AAD.

Özet

Amaç: Kırmızı hücre dağılım genişliği (KHDG) ve nötrofil lenfosit oranı (NLO) ölçümlerinin kardiyovasküler hastalıklarda prognostik önemi olduğu gösterilmiştir. Çıkan aort genişlemesi (ÇAG) aort duvarında enflamasyon ve kistik dejenerasyonla seyreden ve sık görülen kardiyovasküler bir hastalıktır. Bu çalışmada, ÇAG olan hastalarda KHDC ve NLO değerlerini araştırmayı hedefledik.Çalışma planı: Transtrorasik ekokardiyografide ÇAG saptanan 200 hasta ileriye dönük olarak çalışmaya alındı ve çıkan aort çapı normal olan, yaş ve cinsiyet dağılımı benzer 170 bireyle karşılaştırıldı. KHDG, NLO ve ortalama eritrosit hacmi ölçümü için tam kan sayımı (TKS) yapıldı. Geçmiş iki yıl içindeki TKS sonuçları da toplanarak analizlerde ortalama değerler kullanıldı.Bulgular: Çıkan aort genişlemesi olan grupta, KHDG (ortanca 13.9, çeyreklerarası aralık [IQR] 1.40 ve ortanca 13.3, IQR %1.05; p=0.01), NLO (ortanca 2.04, IQR 1.09 ve ortanca 1.78, IQR 0.90; p=0.01) ve yüksek duyarlıklı C-reaktif protein (hs-CRP) ölçümleri (ortanca 0.60, IQR 0.80 ve ortanca 0.44, IQR 0.68 mg/L; p=0.01) kontrol grubuna göre istatistiksel olarak anlamlı şekilde daha yüksekti. Tekli korelasyon analizinde, çıkan aort çapı ile KHDG (r=0.31, p=0.01), NLO (r=0.15, p=0.01) ve hs-CRP (r=0.12, p=0.03) seviyeleri arasında korelasyon saptandı. Çoklu regresyon analizinde ise KHDG ve hs-CRP yüksekliği, ÇAG varlığının bağımsız bir belirteci olarak saptandı. Receiver operating characteristic (ROC) analizinde KHDG için >%13.8 sınır değerinin, ÇAG tanısı için %49.5 duyarlılık ve %82.8 özgüllüğe sahip olduğu bulundu (EAA 0.681, p=0.01).Sonuç: Çıkan aort genişlemesi olan hastalarda, KHDG ve hs- CRP yükselmiştir. Bu değerler, AAD patogenezinde enflamasyonun rolü olabileceğini göstermektedir.
