We evaluated in maintenance hemodialysis patients the potassium lowering effects of intravenous insulin with glucose, nebulized albuterol, and a regimen combining both modalities. There was a similar decrease in plasma potassium following either insulin with glucose (0.65 +/- 0.09 mmol/liter) or albuterol (0.66 +/- 0.12 mmol/liter), and a substantially greater fall with the combined regimen (1.21 +/- 0.19 mmol/liter, P less than 0.02 vs. either drug alone). Baseline plasma glucose concentrations were similar (about 4.8 mmol/liter) prior to all three treatments. Following insulin with glucose, plasma glucose increased transiently. but then fell to 2.8 +/- 0.3 mmol/liter at one hour, with concentrations below 3 mmol/liter in 9 of 12 patients. None of the patients had symptoms of hypoglycemia. Plasma glucose increased to 6.8 +/- 0.5 mmol/liter with albuterol. After the combined drug regimen plasma glucose rose transiently and was back to baseline (4.7 +/- 0.7 mmol/liter) at one hour. Treatment with insulin or albuterol produced trivial increases in heart rate, whereas the combined drug regimen was associated with a significant rise (15.1 +/- 6.0 min-1). These observations suggest that albuterol and insulin with glucose are equally efficacious in lowering plasma potassium in uremic patients, and that the hypokalemic effects of the two drugs is additive. The hypoglycemic effect of insulin is attenuated by coadministration albuterol. Combined therapy with insulin, glucose and albuterol is efficacious and safe for the acute treatment of hyperkalemia in hemodialysis patients. To compare the safety, efficacy and management of insulin lispro (LP) with regular human insulin (RH) in young diabetic children treated with continuous subcutaneous insulin infusion (CSII).
                27 very young diabetic children (age 4.6 +/- 2.2 years) treated with CSII participated in an open-label, randomized cross-over multicenter study comparing 2 periods of 16 weeks of CSII with LP or RH.
                Mean daily basal rate was significantly higher during the LP period (p = 0.04). No differences were seen in changes in HbA1c levels, number of hypoglycemic events, cutaneous infections and catheter occlusions. There was no significant difference between the two treatments for preprandial and postprandial glucose values, although prandial glucose excursions tended to be lower with LP (significant at dinner, p = 0.01). Mean blood glucose levels were significantly higher at 0.00 and 3.00 a.m. during LP therapy (p < 0.05). No episode of ketoacidosis occurred during LP treatment. More parents indicated that LP made their own and the child's daily life easier (p = 0.02) and preferred LP (p = 0.01).
                LP in CSII therapy in children is safe, as effective as RH, improved postprandial excursions, met the needs of young children in their daily life well, and gained their parents' satisfaction and preference. However, a shorter duration of LP resulted in hyperglycemia during the first part of the night, which must be compensated for by increasing nocturnal basal rates during this time. Ten patients with acute and 60 with chronic renal failure (both groups having hyperkalaemia), were managed at Kenyatta National Hospital in the medical wards and Renal Unit between August, 1995 and January, 1996. They were divided into seven different treatment groups, each consisting of ten patients. Treatment A glucose 25g i.v. with insulin 10 units i.v., treatment B 50 mmol of 8.4% sodium bicarbonate infusion, treatment C 0.5mg of salbutamol i.v. in 50mls 5% dextrose, treatment D was a combination of treatments A and B, treatment E was a combination of treatment B and C, treatment F was a combination of treatments A and C while treatment G was a combination of treatments A and B and C. Serum potassium was measured, 30 minutes, 1 hour, 2 hours, 4 hours and 8 hours after treatment. Plasma glucose concentration was measured before treatment was given and 1 hour after in all patients. Electrocardiography was done before treatment on all patients and repeated 30 minutes and 1 hour after treatment for the patients with hyperkalaemic changes on the initial recording. All treatment modalities had satisfactory potassium lowering effects. Of the single therapeutic approaches, treatment A and C were equieffective, but better than treatment B (P < 0.001). Amongst the two regimen combinations, treatment D and F were more efficacious than treatment E and all the single therapeutic approaches (P < 0.001). Treatment G was the most efficacious in lowering serum potassium in this study. All treatment modalities had maximum serum potassium lowering effect at 1-2 hours. A fall in plasma glucose concentration was a notable feature of treatments A and D, but significant hypoglycaemia occurred in 20% of patients receiving treatment A and in none on treatment D. The ECG changes of hyperkalaemia did not correlate with serum potassium levels. The normalisation of hyperkalaemic ECG alteration occurred within the first 30 minutes after treatment. In conclusion, combination therapies for hyperkalaemia appear to be more efficacious than single therapeutic approaches. Inclusion of salbutamol seems to protect against insulin induced hypoglycaemia. The maximum potassium lowering effect is observed 1-2 hours of administration of either agents. The potassium reducing effect remains significant compared to baseline values even after 8 hours. If dialysis cannot be instituted early enough it seems reasonable to repeat treatment every 4-6 hours to sustain the effect. Repeated administration of glucose with insulin may not be safe because of the hypoglycaemic effect. Other single and combination therapies can theoretically be repeated regularly until dialysis is initiated although this requires further clinical evaluation. nan This study was undertaken to test the hypothesis that, given equal arterial pressure reductions, the combination of an angiotensin converting enzyme (ACE) inhibitor and calcium antagonist slows declines in renal function and yields greater reductions in albuminuria over either agent alone. This hypothesis was evaluated in four groups of hypertensive, non-insulin dependent, diabetic subjects with renal insufficiency (N = 30). Renal hemodynamics, albuminuria and metabolic parameters were evaluated for a period of one year. Subjects were all placed on a 90 mEq sodium, 0.8 g/kg protein, 1500 calorie American Diabetes Association diet for the entire length of the study. Subjects were followed for two weeks off antihypertensive medications and were subsequently randomized to either lisinopril, alone (group I), sustained release verapamil, alone (group II), reduced doses of both lisinopril and sustained release verapamil (group III), and hydrochlorothiazide with guanfacine (group IV). At the end of one year group III had the greatest reduction in albuminuria (78 +/- 7%, group III vs. 59% +/- 4, group I: P less than 0.05). In addition, the decline in glomerular filtration rate (GFR) was the lowest in this group (0.28 +/- 0.07, group III vs. 0.69 +/- 0.12, group I; P less than 0.05) although there was no significant difference between groups II and IV. The highest side effect profiles were noted in group IV, the least in group III. The greatest reductions in renal hemodynamics occurred in all groups within the first month; however, striking differences between groups were noted (7.4 +/- 2%, group I vs. 1.4 +/- 2%, group III; P less than 0.05). We conclude that the combination of reduced doses of an ACE inhibitor and calcium antagonist attenuate both albuminuria and the rate of decline in glomerular filtration rate. Furthermore, the combination of these classes of agents appear to yield the lowest side effect profile over either agent alone. Lastly, high doses of ACE inhibition alone may be detrimental to renal function in late stage diabetics with renal insufficiency. Studies involving adults and children being treated in intensive care units indicate that insulin therapy and glucose control may influence survival. Hyperglycemia in very-low-birth-weight infants is also associated with morbidity and mortality. This international randomized, controlled trial aimed to determine whether early insulin replacement reduced hyperglycemia and affected outcomes in such neonates.
                In this multicenter trial, we assigned 195 infants to continuous infusion of insulin at a dose of 0.05 U per kilogram of body weight per hour with 20% dextrose support and 194 to standard neonatal care on days 1 to 7. The efficacy of glucose control was assessed by continuous glucose monitoring. The primary outcome was mortality at the expected date of delivery. The study was discontinued early because of concerns about futility with regard to the primary outcome and potential harm.
                As compared with infants in the control group, infants in the early-insulin group had lower mean (+/-SD) glucose levels (6.2+/-1.4 vs. 6.7+/-2.2 mmol per liter [112+/-25 vs. 121+/-40 mg per deciliter], P=0.007). Fewer infants in the early-insulin group had hyperglycemia for more than 10% of the first week of life (21% vs. 33%, P=0.008). The early-insulin group had significantly more carbohydrate infused (51+/-13 vs. 43+/-10 kcal per kilogram per day, P<0.001) and less weight loss in the first week (standard-deviation score for change in weight, -0.55+/-0.52 vs. -0.70+/-0.47; P=0.006). More infants in the early-insulin group had episodes of hypoglycemia (defined as a blood glucose level of <2.6 mmol per liter [47 mg per deciliter] for >1 hour) (29% in the early-insulin group vs. 17% in the control group, P=0.005), and the increase in hypoglycemia was significant in infants with birth weights of more than 1 kg. There were no differences in the intention-to-treat analyses for the primary outcome (mortality at the expected date of delivery) and the secondary outcome (morbidity). In the intention-to-treat analysis, mortality at 28 days was higher in the early-insulin group than in the control group (P=0.04).
                Early insulin therapy offers little clinical benefit in very-low-birth-weight infants. It reduces hyperglycemia but may increase hypoglycemia (Current Controlled Trials number, ISRCTN78428828.)
                2008 Massachusetts Medical Society Effects of pump treatment vs. four times daily injections were explored in children with diabetes with regard to quality of life and impact of disease as well as adverse effects and parameters of metabolic control.
                An open, parallel, randomized controlled prospective comparative study lasting 14 months was completed by 38 type 1 children with diabetes (age 4-16 yr) following a 3.5-months run-in phase. Standardized quality-of-life Pediatric Quality of life Inventory (PedsQL) and impact of disease scores were obtained every 3.5 months as well as regular medical parameters. Parallel treatment group data and longitudinal within-patient data were analysed for each treatment modality.
                Within-patient comparisons of the two treatment modalities showed significant improvement in PedsQL and impact scores after pump treatment. Treatment group comparisons did not show significant improvement. Pump treatment resulted in decreased symptomatic hypoglycaemia and lowered haemoglobin A1c by 0.22% after run in.
                Within-patient comparison suggests that metabolic control, frequency of severe hypoglycaemia (a threefold decrease), quality of life and impact of disease scores are improved by pump treatment in comparison to regular treatment with four daily insulin injections. Several studies have demonstrated that diabetic patients with cirrhosis require insulin treatment because of insulin resistance. As chronic alcoholic liver damage is partly due to the lipoperoxidation of hepatic cell membranes, anti-oxidizing agents may be useful in treating or preventing damage due to free radicals. The aim of this study was to ascertain whether long-term treatment with silymarin is effective in reducing lipoperoxidation and insulin resistance in diabetic patients with cirrhosis.
                A 12-month open, controlled study was conducted in two well-matched groups of insulin-treated diabetics with alcoholic cirrhosis. One group (n=30) received 600 mg silymarin per day plus standard therapy, while the control group (n=30) received standard therapy alone. The efficacy parameters, measured regularly during the study, included fasting blood glucose levels, mean daily blood glucose levels, daily glucosuria levels, glycosylated hemoglobin (HbA1c) and malondialdehyde levels.
                There was a significant decrease (p<0.01) in fasting blood glucose levels, mean daily blood glucose levels, daily glucosuria and HbA1c levels already after 4 months of treatment in the silymarin group. In addition, there was a significant decrease (p<0.01) in fasting insulin levels and mean exogenous insulin requirements in the treated group, while the untreated group showed a significant increase (p<0.05) in fasting insulin levels and a stabilized insulin need. These findings are consistent with the significant decrease (p<0.01) in basal and glucagon-stimulated C-peptide levels in the treated group and the significant increase in both parameters in the control group. Another interesting finding was the significant decrease (p<0.01) in malondialdehyde/levels observed in the treated group.
                These results show that treatment with silymarin may reduce the lipoperoxidation of cell membranes and insulin resistance, significantly decreasing endogenous insulin overproduction and the need for exogenous insulin administration. Improved blood-glucose control decreases the progression of diabetic microvascular disease, but the effect on macrovascular complications is unknown. There is concern that sulphonylureas may increase cardiovascular mortality in patients with type 2 diabetes and that high insulin concentrations may enhance atheroma formation. We compared the effects of intensive blood-glucose control with either sulphonylurea or insulin and conventional treatment on the risk of microvascular and macrovascular complications in patients with type 2 diabetes in a randomised controlled trial.
                3867 newly diagnosed patients with type 2 diabetes, median age 54 years (IQR 48-60 years), who after 3 months' diet treatment had a mean of two fasting plasma glucose (FPG) concentrations of 6.1-15.0 mmol/L were randomly assigned intensive policy with a sulphonylurea (chlorpropamide, glibenclamide, or glipizide) or with insulin, or conventional policy with diet. The aim in the intensive group was FPG less than 6 mmol/L. In the conventional group, the aim was the best achievable FPG with diet alone; drugs were added only if there were hyperglycaemic symptoms or FPG greater than 15 mmol/L. Three aggregate endpoints were used to assess differences between conventional and intensive treatment: any diabetes-related endpoint (sudden death, death from hyperglycaemia or hypoglycaemia, fatal or non-fatal myocardial infarction, angina, heart failure, stroke, renal failure, amputation [of at least one digit], vitreous haemorrhage, retinopathy requiring photocoagulation, blindness in one eye, or cataract extraction); diabetes-related death (death from myocardial infarction, stroke, peripheral vascular disease, renal disease, hyperglycaemia or hypoglycaemia, and sudden death); all-cause mortality. Single clinical endpoints and surrogate subclinical endpoints were also assessed. All analyses were by intention to treat and frequency of hypoglycaemia was also analysed by actual therapy.
                Over 10 years, haemoglobin A1c (HbA1c) was 7.0% (6.2-8.2) in the intensive group compared with 7.9% (6.9-8.8) in the conventional group--an 11% reduction. There was no difference in HbA1c among agents in the intensive group. Compared with the conventional group, the risk in the intensive group was 12% lower (95% CI 1-21, p=0.029) for any diabetes-related endpoint; 10% lower (-11 to 27, p=0.34) for any diabetes-related death; and 6% lower (-10 to 20, p=0.44) for all-cause mortality. Most of the risk reduction in the any diabetes-related aggregate endpoint was due to a 25% risk reduction (7-40, p=0.0099) in microvascular endpoints, including the need for retinal photocoagulation. There was no difference for any of the three aggregate endpoints between the three intensive agents (chlorpropamide, glibenclamide, or insulin). Patients in the intensive group had more hypoglycaemic episodes than those in the conventional group on both types of analysis (both p<0.0001). The rates of major hypoglycaemic episodes per year were 0.7% with conventional treatment, 1.0% with chlorpropamide, 1.4% with glibenclamide, and 1.8% with insulin. Weight gain was significantly higher in the intensive group (mean 2.9 kg) than in the conventional group (p<0.001), and patients assigned insulin had a greater gain in weight (4.0 kg) than those assigned chlorpropamide (2.6 kg) or glibenclamide (1.7 kg).
                Intensive blood-glucose control by either sulphonylureas or insulin substantially decreases the risk of microvascular complications, but not macrovascular disease, in patients with type 2 diabetes.(ABSTRACT TRUNCATED)
In view of the limited information from small studies of uncertain quality, no firm recommendations for clinical practice can be made. It appears that the combination of insulin and glucose is preferred over treatment with rectal cation-resin for hyperkalaemia in preterm infants. Both the combination of insulin and glucose and albuterol inhalation deserve further study. The two interventions could possibly be tested against each other. The effectiveness of other potentially effective interventions for non-oliguric hyperkalaemia (diuretics, exchange transfusion, peritoneal dialysis and calcium) have not been tested in randomised controlled trials.
