Abstract (2. Language): 
Homocysteine (Hey) is an independent risk factor for atherosclerosis. Since atherosclerotic cardiovascular events are the most frequent death causes in end stage renal disease patients, in the present study, plasma total Hey levels, their relationship with renal functions and nutritional status and the effect of hemodialysis on plasma total Hey levels were investigated in hemodialysis patients. In 16 hemodialysis patients, pre- and postdialysis plasma total Hey , serum urea, creatinine and albumin levels were determined. As an indicator of dialysis adequacy, URR (urea reduction rate) values of the patients were calculated. The control group was consisted of 16 healthy subjects and their plasma total Hey levels were also measured. Predialysis plasma total Hey levels of the patients were compared to those of the controls and to the postdialysis levels. Additionally, it was also investigated whether predialysis and postdialysis plasma total Hey levels of the patients had relationship with serum urea, creatinine, albumin levels and URR values. The both of pre- and postdialysis levels of plazma total homosistein were higher than those of controls. While pre- and postdialysis plazma total homosistein levels had no correlation with nutritional statues of the patients, they had significant correlation with URR values. In conclusion, hemodialysis patients have elevated plasma total Hey levels. Although there is a reduction in plasma total Hey levels after hemodialysis session, they do not return to the normal in postdialysis period.
Abstract (Original Language): 
Homosistein (Hey) ateroskleroz için bağımsız bir risk faktörüdür. Son dönem böbrek hastalarında aterosklerotik kardiyovasküler olaylar en sık ölüm nedeni olduğundan bu çalışma hemodiyaliz hastalarından oluşan bir grupta plazma Hey düzeylerinin durumunu belirlemek, böbrek fonksiyonları ile ilişkisini incelemek, beslenme durumu ile olan ilişkisini saptamak ve hemodiyalizin plazma Hey düzeyleri üzerine olan etkisini araştırmak amacıyla gerçekleştirildi. On altı hemodiyaliz hastasının diyaliz öncesi ve sonrası plazma total Hey, serum üre, kreatinin ve albümin değerleri belirlendi. Hemodiyaliz yeterliliğinin bir göstergesi olarak URR (urea reduction rate) değerleri belirlendi. Kontrol grubu 16 sağlıklı bireyden oluşturuldu ve plazma total Hey düzeyleri saptandı. Hastaların diyaliz öncesi ve sonrası plazma total Hey düzeyleri kontrollerinkilerle ve birbirleri ile kıyaslandı. Ayrıca hastaların diyaliz öncesi ve sonrası plazma total Hey düzeylerinin serum üre, kreatinin, albümin düzeyleri ve URR değerleri ile olan ilişkisi araştırıldı. Çalışma grubunun diyaliz öncesi ve sonrası plazma total Hey düzeylerinin kontrollerinkinden anlamlı olarak yüksek olduğu, beslenme durumu ile ilişkili olmadığı ancak URR ile anlamlı ilişkili olduğu belirlendi. Sonuç olarak hemodiyaliz hastaları yüksek plazma total Hcyin düzeylerine sahiptirler. Son dönem böbrek hastalarında hemodiyaliz tedavisi tek başına plazma Hey düzeylerinin normal değerlerine dönmesi için yeterli olamamaktadır.
