Giriş: Kardiyovasküler hastalıklar halen dünyada mortalite ve morbiditenin en önemli nedenidir. Kalp cerrahisi hastanelerde en sık uygulanan büyük cerrahi girişimler olup, cerrahi sonrası gelişen akut böbrek hasarı (ABH) sıklıkla karşılaşılan ve mortaliteyi arttıran önemli bir durumdur. Operasyon sonrası gelişebilecek ABH erken tanısının belirlenmesi tedavi başarısını yükseltebilir. Biz de bu çalışmada kardiyak cerrahi geçiren hastalarda postoperative Cystatin C düzeyinin erken dönem akut böbrek yetmezliği ile ilişkisini değerlendirmeyi amaçladık.
Yöntemler: Çalışmamız 2016 - 2017 yılları arasında kardiyak operasyon geçiren, 18 yaşından büyük, başlangıç böbrek fonksiyonu normal (kreatinin <1,2 mg/dL) 40 erişkin hasta ile yapıldı. Hastaların bazal demografik özellikleri, biyokimya parametreleri kayıt edildi. Plazma Cystatin C seviyesi postop 6. saat ve 24. saat örnekleri alınarak postop ABH arasındaki ilişkisi araştırıldı.
Bulgular: Çalışmamızda 40 hastadan 12’sine Akut Kidney Injury Network (AKIN) ve 14’üne Risk-Injury-Failure-Loss-End stage (RIFLE) sınıflamasına göre ABH tanısı konuldu. ABH gelişmesi ile hastanede kalış süresinin anlamlı olarak arttığı, 24. saat Cystatin C seviyesinin ABH gelişmesi ile korele olduğu (p=0.048) ve ABH gelişen grupta anlamlı olarak yüksek olduğu belirlendi. Başlangıç diyabet varlığı ABH gelişen hastalarda anlamlı olarak yüksekti (p=0.045). Plazma Cystatin C 24. saat AUCROC değeri 0,78 (0,75-0,90 Güven aralığı, p:0.002) olarak hesaplandı. 6.saatte bakılan Cystatin C seviyesi ile ABH arasında korelasyon yoktu (p=0.358).
Sonuç: Kardiyak cerrahi sonrası ABH gelişmesi olumsuz klinik olay sıklığı ile ilişkilidir. 6.saat bakılan Cystatin C erken tanıda duyarlılığı düşük, 24.saat bakılan Cystatin C ise erken tanıda güçlü tanısal değere sahiptir. Postoperatif Cystatin C düzeyi ABH tanısında (özellikle 24.saatte) önemli katkı sağlayabilir.

THE RELATIONSHIP OF POSTOPERATIVE CYSTATIN C LEVEL WITH EARLY ACUTE RENAL FAILURE IN ADULT PATIENTS UNDERGOING CARDIAC SURGERY

Öz

Introduction: Cardiovascular diseases are still the most important cause of mortality and morbidity in the world. Cardiac surgery is the most frequently performed major surgical intervention in hospitals, and acute kidney injury (AKI) that develops after surgery is an important condition that is frequently encountered and increases mortality. The success of treatment may be increased by early detection of AKI that may appear following surgery. In this study, we sought to assess how early stage acute renal failure and postoperative Cystatin C levels related in patients underwent cardiac surgery.
Methods: 40 adult patients over the age of 18 who underwent cardiac surgery between 2016 and 2017 participated in our study. All of the participants had baseline renal function that was normal (creatinine 1.2 mg/dL). The patients' baseline biochemistry values and demographics were noted. The link between postoperative AKI and plasma cystatin C level was examined using samples collected at 6 hours and 24 hours.
Results: In our study, 12 out of 40 patients were diagnosed with AKI according to the Akut Kidney Injury Network (AKIN) classification and 14 according to the Risk-Injury-Failure-Loss-End stage (RIFLE) classification.It was determined that the duration of hospital stay increased significantly with the development of AKI, the 24th hour Cystatin C level was correlated with the development of AKI (p:0.048) and was significantly higher in the group developing AKI. Presence of baseline diabetes was significantly higher in patients who developed AKI (p:0.045). Plasma Cystatin C 24-hour AUCROC value was calculated as 0.78 (0.75-0.90 Confidence interval, p:0.002). There was no correlation between Cystatin C level measured at 6th hour and AKI (p:0.358).
Conclusion: The development of AKI after cardiac surgery is associated with the frequency of adverse clinical events. Cystatin C tested at 6 hours has low sensitivity in early diagnosis, while Cystatin C at 24 hours has a strong diagnostic value in early diagnosis. Postoperative Cystatin C level can make a significant contribution to the diagnosis of AKI (especially at the 24th hour).
