Abstract (2. Language): 
Lipid disorder is a well-known problem in hemodialysis (HD) patients. This condition is an important risk factor for cardiovascular disease. Although a positive effect of l ow molecular weight heparin (LMWH) upon lipid profile has been proposed in HD patients, this consequence is still controversial. Furthermore, HD patients are exposed to chronic inflammation that is also known as a risk factor for cardiovascular disease. In this study, we compared the effect of LMWH and standard heparin (SH) on lipid profile and Creactive protein that is one of the inflammation markers. In this prospective, randomized, and cross-over study, 30 HD patients were enrolled in the study. They were randomly divided into two groups. SH was administered to group I and LMWH was administered to group II. Blood samples were drawn before HD sessions at the beginning, eight weeks before and after switching the therapy. The study was finished at the sixteenth week. Lipid profile, high sensitivity-CRP and albumin were determined. Serum lipid parameters and serum albumin levels, which we¬ re determined at the beginning, before and after switching the the¬ rapy, were not significantly changed (p>0.05). However, CRP was significantly reduced in patients treated with LMWH before and af¬ ter switching therapy (p<0.05). Neither LMWH nor SH has an effect upon serum lipid and albumin levels. More than two months may be required to cause significant changes in lipid profile and serum albumin levels in HD patients. However, we demonstrated a decrease in the inflammation, which is responsible for the cardiovascular morbidity and mortality, independently from the serum lipid and albumin levels. Although long-term studies are warranted, our results indicate that LMWH should be preferred for anticoagulation in HD patients due to its beneficial effects upon inflammation.
Abstract (Original Language): 
Hemodiyaliz (HD) hastalarında lipid profilinde bozulma olduğu bilinmektedir. Bu durum kardiyovasküler hastalık açısından önemli bir risk faktörüdür. Düşük moleküler ağırlıklı heparinin (DMAH) HD hastalarında serum lipid profili üzerine olumlu etkileri olduğu ileri sürülmesine rağmen, bu konu halen tartışmalıdır. Ayrıca HD hastalarında kronik bir inflamasyon olduğu ve bunun da kardiyovasküler hastalık açısından bir risk faktörü ol¬ duğu bilinmektedir. Bu çalışmada, DMAH'nin ve standart heparinin (SH) lipid profili üzerine ve inflamasyon parametrelerinden biri olan C-reaktif protein (CRP) üzerine olan etkileri, ileriye dönük, çapraz değişimli olarak karşılaştırıldı. ileriye dönük, rasgele yöntemli, çapraz değişimli çalışma olarak tasarlanmış olan bu çalışmada, çalışma şartlarına uygun 30 kronik hemodiyaliz hastası alındı. Hastalar rasgele yöntemle 15'er kişilik iki gruba ayrıldı. Grup I'deki hastalara SH, grup Il'deki hastalara ise DMAH (dalteparin) verildi. Hastalar 16 hafta boyunca takip edildi. Çalışmanın başlangıcında, sekizinci haftanın sonunda tedavi rejimi değiştirilmeden önce ve takip eden sekiz hafta sonra her iki gruptan diyalizden hemen önce kan örnekleri alınarak on altıncı hafta sonunda çalışma bitirildi. Lipid profili ile birlikte yüksek duyarlılıklı CRP ve albümin değerlendirildi. Başlangıçta, tedavi rejimi değiştirilmeden hemen önce ve değiştiril¬ dikten sonra değerlendirilen lipid parametrelerinde ve serum albümin se¬ viyelerinde istatistiksel olarak anlamlı bir değişim gözlenmezken (p>0.05), değişim öncesi ve değişim sonrasında DMAH kullanılan olgularda CRP istatistiksel olarak anlamlı azalma gösterdi (p<0.05). HD hastalarında iki aylık süre içinde lipid profiline etki açısından SH ile DMAH arasında fark gözlenmedi. Ancak lipid profilindeki ve albümin seviyelerindeki değişimden bağımsız olarak kardiyovasküler morbiditeden ve belki de mortaliteden sorumlu olan inflamasyon, DMAH ile anlamlı olarak azalmıştır. Daha uzun dönemli çalışmaların yapılması gerekmekle birlikte, lipid parametrelerinde değişim olmaksızın inflamasyonda gözlenen olumlu etkisini göz önünde bulundurduğumuzda, antikoagülasyonun zorunlu olduğu HD'de DMAH'lerin SH'ye oranla daha avantajlı olduğu ifade edilebilir.
