title: [Serum beta 2-microglobulin as a index of the initiation of dialysis therapy for diabetic patients with chronic renal failure].
abstract: This study was designed whether serum beta 2-microglobulin is good index for the initiation of dialysis therapy in diabetic patients with chronic renal failure. Serum creatinine (S. Cr), beta 2-microglobulin (S. beta 2-MG) and guanidinoacetic acid (S. GAA) were measured in dialyzed or undialyzed diabetic patients with chronic renal failure in comparison with non diabetic patients. 28.6% of diabetic patients showed S. Cr below 8.0 mg/dl at the initiation of dialysis therapy although all of non diabetic patients showed it over 8.0 mg/dl. On the other hand, there was no significant difference in S. beta 2-MG between diabetic and non diabetic patients, and all patients of the two groups showed S. beta 2-MG over 12.0 mg/l. In non diabetic patients whose S. Cr was below 8.0 mg/dl, undialyzed patients had a significant correlation between S. Cr and S. beta 2-MG (r = 0.840, P less than 0.01), and all non diabetic patients showed relatively high value of S. Cr as compared with that of beta 2-MG at the initiation of dialysis therapy. Undialyzed diabetic patients whose S. Cr was below 8.0 mg/dl also revealed a close correlation between serum creatinine and beta 2-MG (r = 0.864, P less than 0.01), but dialyzed diabetic patients showed different correlation between S. Cr and S. beta 2-MG from it of non diabetic patients and S. Cr was underestimated as compared with S. beta 2-MG. Undialyzed diabetic patients showed significant lower values of S. Cr and S. GAA of non diabetic patients whose S. beta 2-MG were almost same as diabetics.(ABSTRACT TRUNCATED AT 250 WORDS)
