Sustained normoglycemia in newly diagnosed type I diabetic subjects. Short-term effects and one-year follow-up

K Perlman, RM Ehrlich, RM Filler and AM Albisser

The impact on remission of normalizing blood glucose levels immediately after diagnosis of type I diabetes was studied in 14 adolescents. Accordingly, in this randomized prospective primary intervention study, 7 of the subjects (i.v. group) received insulin by continuous intravenous (i.v.) infusion via a portable preprogrammed system for 28-62 days and 7 (s.c. group) received conventional subcutaneous (s.c.) therapy. Before therapy, the two groups did not differ significantly with respect to glycosylated hemoglobin, fasting plasma C-peptide, or 24-h urinary C-peptide excretion. During the infusion period, the overall mean fasting plasma glucose (FPG) concentration for the i.v. group was 84 mg/dl with a mean coefficient of variation of 18 +/- 4% (mean +/- SD). During the comparable period for the s.c. group, the mean FPG was 253 mg/dl with a coefficient of variation of 30 +/- 20%. Twenty-four-hour urinary glucose excretions for the two groups were 0.29 +/- 0.06 (mean +/- SEM) and 59 +/- 11 g/day, respectively. Daily insulin requirements in the i.v. group decreased from 1.47 +/- 0.19 U/kg body wt/day at the start to 0.47 +/- 0.10 U/kg/day at the end of the infusion period. Notably, 10-25 days after the infusion period, 5 of 7 subjects experienced a further decrease to a low of 0.27 +/- 0.01 U/kg/day. The mean peak and low requirements in the s.c. group were 0.71 +/- 0.15 and 0.33 +/- 0.13 U/kg/day, respectively, with the only peak requirements being significantly different (P less than 0.01). No patient was able to discontinue insulin therapy.(ABSTRACT TRUNCATED AT 250 WORDS)
