    Abstract:
    Clinical feature and creatinine metabolism were studied in 86 diabetic patients who had newly initiated dialysis treatment. In 32.5% of the patients, serum creatinine was below 8.0 mg/dl at the initiation of dialysis treatment. Gastrointestinal symptoms, general malaise, pulmonary edema and uremic encephalopathy were the causes which required dialysis treatment in those patients, and the frequency of pulmonary edema was significantly higher than in patients whose serum creatinine was above 8.0 mg/dl at the initiation of dialysis (p less than 0.05). There were no significant differences in serum urea nitrogen, potassium, sodium, albumin levels and hematocrit between low serum creatinine group (3.0-7.9 mg/dl) and high serum creatinine group (8.0-11.9 mg/dl) at the initiation of dialysis. Serum creatinine levels were highly correlated with creatinine generation rate (r = 0.788, p greater than 0.01). There was a significant correlation between creatinine generation rate and muscle volume (r = 0.863, p less than 0.001). Muscle volume of diabetic dialyzed patients was 29.5 +/- 7.0 cm3/cm in males and 26.9 +/- 5.0 cm3/cm in females, and those values were lower than those of non-diabetic dialyzed patients (p greater than 0.005). Frequency of the patients whose creatinine generation rate was below 1500 mg/day was 81.3% in diabetic hemodialyzed patients and this was significantly higher than in non-diabetic hemodialyzed patients (p less than 0.005). In conclusion, in patients with diabetic nephropathy who have to initiate dialysis treatment, uremic symptoms have progressed though serum creatinine levels are relatively low. This low serum creatinine levels in patients with diabetic end-stage renal disease are resulted from their low muscle volume.
