Abstract (2. Language): 
Peritoneal dialysis (PD) is a commonly used renal replacement method. These patients lose 5-10 gram/ day protein during the dialysis procedure. The losses are greater in high transporters, during the peritonitis attack and in case of peritoneal fibrosis. Urine Protein / Creatinine ratio is a practical method and used to estimate daily protein loss in clinical nephrology. The aim of the present study was to investigate the relationship between dialysate proteine/creatinine ratio and daily protein loss. We studied 12 stable PD patients [6 men, 6 women; mean age: 31 ± 8 years. Patients underwent a standard peritoneal equilibration test (PET). In addition, dialysate protein was measured in fourth hour samples and 24 hours dialysate samples. Daily protein loss calculated from protein/creatinine ratio and from protein in the 24 hours samples* daily dialysate volume. The mean of protein loss in the dialysate was 9.3±2.8 g/day and 11.5+3.5 g/day in the 24 hours sample and protein/creatinine ratio, respectively. There is a significant correlation between two methods (r=0.71, p< 0.05). In conclusion, according to our results, Protein/ Creatinine ratio is a useful method to estimate daily protein loss in the patients underwent routine PET
Abstract (Original Language): 
Periton diyalizi (PD), günümüzde sıkça kullanılan bir renal replasman tedavisidir. Diyalizat ile ortalama olarak 5-10 gr/gün kadar protein kaybedilmektedir. Yüksek geçirgen olanlarda, peritonit sırasında ve peritoneal fibrozis durumlarında diyalizat protein kaybı artmaktadır. Diyalizattaki protein kaybı ile düşük serum albumin ve peritoneal transport arasında ilişki olduğu bilinmektedir. Spot idrarda protein/kreatinin oranı, günlük protein kaybım saptamak için nefrolojide sıkça kullanılan pratik bir yöntemdir. Bu çalışmada, benzer bir yaklaşımla, PET diyalizat örneğinde P/Kr oranı ile günlük diyalizat protein kaybı arasındaki ilişkiyi araştırmayı amaçladık. PD poliklinik takibinde olan stabil 12 hasta (ortalama yaş 31 ±8 yıl; 6 K, 6E) çalışmaya alındı. 24 saatlik diyalizat ve PET3 (4 saat) diyalizat örnekleri alındı. Turbimetrik yöntemle örneklerde protein çalışıldı. Günlük protein kaybı: protein x günlük diyalizat volumü ve PET3 diyalizat örneğinde P/Kr oranı kullanılarak hesaplandı ve korelasyon analizi uygulandı. Ortalama günlük diyalizat protein kaybı; 24 saatlik örneğe göre 9.3±2.8 g/gün bulunurken; Pr/ Kr' ne göre ise 11.5+3.5 gr/gün bulundu. İki yöntem arasında yapılan korelasyon analizinde r =0.71 bulundu (p< 0.05). Tarafımızca yapılan bu ön çalışmada; PET örneğinden bakılan Pr/kret oranının günlük protein kaybını %71 oranında yansıttığı saptanmıştır. Kanımızca PET3 prot/kreat oranı günlük diyalizat protein kaybını tahmin etmede kullanılabilecek, PET sırasında ek bir işlem gerektirmeden yapılabilecek, kolay bir yöntem olabilir.
