insulin--isophane and Albuminuria

To analyse data from a randomised, controlled study of prandial insulin aspart versus human insulin, both with NPH insulin, in pregnant women with type 1 diabetes for potential factors predicting poor pregnancy outcomes. RESEARCH DESIGN/METHOD: Post hoc analysis including 91 subjects randomised prior to pregnancy with known outcome in early pregnancy and 259 subjects randomised prior to pregnancy/during pregnancy of <10 weeks' gestation with known late-pregnancy outcomes. Poor early-pregnancy outcomes included fetal loss <22 gestational weeks and/or congenital malformation (n=18). Poor late-pregnancy outcomes included: composite endpoint including pre-eclampsia, preterm delivery and perinatal death (n=78); preterm delivery (n=63); and excessive fetal growth (n=88).. 18 patients experienced a malformed/lost fetus in early pregnancy - none preceded by severe hypoglycaemia. Albuminuria in early pregnancy was a significant predictor of poor late-pregnancy outcome (composite endpoint; p=0.012). In the third trimester, elevated HbA1c, ≥ 1 plasma glucose (PG) measurement >11 mmol/L (198 mg/dL) and %PG values outside 3.9-7.0 mmol/L (70-126 mg/dL) were significant predictors of poor late-pregnancy outcomes (all p<0.05).. Elevated HbA1c, high glucose spikes and out-of-range %PG in the third trimester, and albuminuria in early pregnancy, are associated with poor late-pregnancy outcomes.

The aim of this study was to compare the metabolic effects of a combination of daytime glibenclamide and evening NPH insulin with intensive insulin treatment (rapid acting insulin before meals and NPH insulin at bedtime) in patients exhibiting secondary failure to sulphonylurea treatment. Thirty-nine mildly obese NIDDM patients (BMI 25.6 +/- 0.5) were randomized after 6 weeks of intensive insulin treatment to either a combination treatment (CT, n = 20) or continued intensive insulin treatment (IT, n = 19). There were no differences between the two groups in age, diabetes duration, BMI, HbA1c, or basal and glucagon stimulated C-peptide. The patients were followed for 1 year and the findings were analysed on an intent to treat basis. Two patients in the CT group were excluded after 2 and 6 months, respectively, due to unacceptably high postprandial glucose values. There was a significant difference in HbA1c between the CT and IT groups at 6 months (8.2 +/- 0.2, n = 19, vs 6.8 +/- 0.4%, n = 19, p < 0.001)), but not at 12 months (7.8 +/- 0.3, n = 18, vs 7.5 +/- 0.4%, n = 19). After the initial intensive insulin treatment, BMI was constant in the CT group but increased significantly at 6 and 12 months in the IT group. We conclude that both treatments are associated with a marked and long-term improvement of glycaemic control. The intensive insulin treatment leads to a more pronounced weight increase which in the long run might have negative effect on overall metabolic control. Therefore, the combination treatment together with intensified education and dietary advice should be regarded as the initial treatment of choice for oral agent failure in moderately obese NIDDM patients.

It was decided to demonstrate by the present observations to which extent beneficial long-term effects on metabolic control, body weight and microalbuminuria can be attained by applying intensive insulin therapy (IIT) to type 2 diabetic patients, particularly when using insulin lispro.. In our observational study, clinical data were evaluated during 6, 12 and 36 months after participation in our structured inpatient insulin treatment and teaching programme in 25 patients with conventional insulin therapy (CT), in 10 patients with IIT using human normal insulin and in 15 patients with IIT using insulin lispro who all could be followed for 3 years in our outpatient diabetic clinic.. In the CT-treated patients, HbA1c decreased from 10.2 +/- 0.4% to 7.6 +/- 0.2% (average +/- SEM) after 3 years. Body weight increased from 27.8 +/- 0.9 kg/m2 to 28.6 +/- 0.9 kg/m2, insulin dose increased from 29 +/- 3 U/day to 48 +/- 5 U/day (all p < 0.05), urinary albumin concentration was only transiently reduced. In the IIT-treated patients using human normal insulin, HbA1c fell from 10.6 +/- 0.8% to 7.9 +/- 0.5%, body weight increased from 27.8 +/- 1.4 kg/m2 to 29.8 +/- 1.3 kg/m2, urinary albumin concentration was reduced from 26 +/- 10 mg/l to 13 +/- 3 mg/l (all p < 0.05). Insulin dose increased only slightly from 57 +/- 6 U/day to 63 +/- 7 U/day. In the IIT-treated patients using insulin lispro HbA1c fell from 8.4 +/- 0.5% to 6.7 +/- 0.3%, body weight increased from 27.6 +/- 1.0 kg/m2 to 28.7 +/- 1.3 kg/m2, insulin dose from 36 +/- 5 U/day to 50 +/- 7 U/day, urinary albumin concentration was reduced from 23 +/- 4 mg/l to 13 +/- 4 mg/l (all p < 0.05). Blood pressure remained uninfluenced by insulin therapy.. In our patients, we observed a beneficial long-term effect on metabolic control of IIT-treatment using insulin lispro, which was evident over the complete 3-year observation period, together with an only moderate increase in insulin dose and a clinically acceptable increase in body weight, but a remarkable reduction of microalbuminuria. Thus, clinical outcome was superior to that in patients treated with CT or IIT using human normal insulin.
