Reduction of urinary albumin excretion after 4 years of continuous subcutaneous insulin infusion in insulin-dependent diabetes mellitus. The Oslo Study.
Urinary albumin was studied in 45 patients with insulin-dependent diabetes in a 4-year prospective randomized trial, comparing continuous sc insulin infusion (CSII), multiple insulin injections, and conventional treatment with twice daily injections. Strict blood glucose control was obtained with CSII and multiple injections, better than with conventional treatment (2P less than 0.01): mean glycosylated haemoglobin (% HbA1 +/- SEM) after 4 years: CSII 9.0 +/- 0.4%; multiple injections 9.4 +/- 0.4%; conventional treatment 10.5 +/- 0.5. A total of 696 24-h urine specimens were collected. After 4 years of CSII from the time of randomization, urinary albumin excretion was reduced (26 +/- 5 to 16 +/- 4 mg/24 h, mean +/- SEM, 2P less than 0.01), when compared with conventional treatment (2P = 0.01), when compared with conventional treatment (2P = 0.01) where no change was observed (21 +/- 4 to 22 +/- 6 mg/24 h, n.s.). The reduction observed during multiple injection treatment was not significant (17 +/- 3 to 14 +/- 3 mg/24 h). Long-term near-normoglycaemia may influence the mechanisms leading to albuminuria in diabetes, if introduced at an early stage of the disease.
