Abstract

Worldwide, cardiac surgery is a common procedure requiring a large quantity of allogeneic blood prod- ucts, which are associated with postoperative complications. Leukocytes present in blood products may play a role in these complications, which are referred to as transfusion-related immunomodulation (TRIM). Several randomized controlled trials (RCTs) in different settings investigated the effects of allo- geneic leukocytes in red blood cells (RBCs). Cardiac surgery studies reported a reduction in postoperative infections and mortality in patients that received leukocyte-reduced RBCs compared with leukocyte-con- taining RBCs; this was mainly due to more deaths due to infections and multiple organ dysfunction syn- drome (MODS) in the group that received leukocyte-containing RBCs. Patients with postoperative com- plications had higher concentrations of inflammatory mediators. These findings suggest that leukocyte- containing transfusion during cardiac surgery induces a second insult to the systemic inflammatory response. In the present review we discuss the possible role of blood transfusions in cardiac surgery. Especially, we focus on the possible role of allogeneic leukocytes associated with postoperative complica- tions after cardiac surgery

Özet

Kalp cerrahisi, postoperatif komplikasyonlarla ilişkilendirilen çok sayıda allogeneik kan ürünlerini gerektiren dünya genelinde yaygın bir girişimdir. Kan ürünlerinde bulunan lökositler, transfüzyon ile ilişkili immünomodülasyon (TRIM) olarak adlandırılan bu tür etkilerde bir rol oynayabilir. Alyuvarlarda (RBC) allogeneik lökositlerin etkisinin araştırılması için farklı koşullarda çeşitli rasgele (randomize) kontrollü çalışmalar yapılmaktadır. Kalp cerrahisi çalışmalarında lökosit içeren RBC uygulanan hastalarda postoperatif enfeksiyonlar ve mortalitede maliyet etkinliği sağlayan bir azalma gösterilmiştir. Bu etkiler temelde enfeksiyonlar ve çoklu organ disfonksiyonu sendromuna bağlı daha fazla ölümden kaynaklanır. Postoperatif komplikasyonlu hastalarda enflamatuvar mediyatörler daha yüksek konsantrasyonlarda mevcuttur. Bu bulgular kalp cerrahisi sırasında lökosit içeren transfüzyonların sistemik enflamatuvar yanıta bağlı bir hasara neden olduğunu düşündürmektedir. Bu incelemede kalp cerrahisinde allogeneik lökositlerin olası rolleri ele alınmaktadır. Allogeneik lökositlerin rolünün anlaşılabilmesi için olası mekanizmalar önerilmektedir.
