RESUMEN

INTRODUCTION: Using pooled data from the REALI European database, we evaluated the impact of previous basal insulin (BI) type on real-life effectiveness and safety of switching to insulin glargine 300 U/ml (Gla-300) in people with suboptimally controlled type 2 diabetes. METHODS: Patient-level data were pooled from 11 prospective, open-label, 24-week studies. Participants were classified according to the type of prior BI. Of the 4463 participants, 1282 (28.7%) were pre-treated with neutral protamine Hagedorn (NPH) insulin and 2899 (65.0%) with BI analogues (BIAs), and 282 (6.3%) had undetermined prior BI. RESULTS: There were no meaningful differences in baseline characteristics between subgroups, except for a higher prevalence of diabetic neuropathy in the NPH subgroup (21.6% versus 7.8% with BIAs). Mean ± standard deviation haemoglobin A1c (HbA1c) decreased from 8.73 ± 1.15% and 8.35 ± 0.95% at baseline to 7.71 ± 1.09% and 7.82 ± 1.06% at week 24 in the NPH and BIA subgroups, respectively. Least squares (LS) mean change in HbA1c was - 0.85% (95% confidence interval - 0.94 to - 0.77) in NPH subgroup and - 0.70% (- 0.77 to - 0.64) in BIA subgroup, with a LS mean absolute difference between subgroups of 0.16 (0.06-0.26; p = 0.002). Gla-300 mean daily dose was slightly increased at week 24 by 0.07 U/kg/day (approximately 6 U/day) in both subgroups. Incidences of symptomatic and severe hypoglycaemia were low, without body weight change. CONCLUSIONS: Irrespective of previous BI therapy (NPH insulin or BIAs), switching to Gla-300 improved glycaemic control without weight gain and with low symptomatic and severe hypoglycaemia incidences. However, a slightly greater glucose-lowering effectiveness was observed in people pre-treated with NPH insulin.

RESUMEN

INTRODUCTION: Hospitalized patients with diabetes receiving corticosteroids are at risk of developing hyperglycemia and related complications. This study evaluated a neutral protamine Hagedorn (NPH) insulin-based protocol in improving glycemic control in hospitalized patients receiving corticosteroids. METHODS: This was a randomized, prospective, non-blinded study in an inpatient setting involving patients with diabetes who were hospitalized and receiving prednisone ≥ 10 mg per day or equivalent. High dose corticosteroids group (prednisone > 40 mg/day or equivalent) received NPH insulin 0.3 U/kg between 0600 and 2000 hours if eating or 0.2 U/kg between 2000 and 0600 hours if not eating. Low dose corticosteroids group (prednisone 10-40 mg/day or equivalent) received 0.15 U/kg between 0600 and 2000 hours if eating or 0.1 U/kg between 2000 and 0600 hours if not eating. Primary outcome measure was mean blood glucose level measured pre-meal and at bedtime for days 1-5. RESULTS: Mean blood glucose level was lower in the intervention (n = 29) than in the usual care (n = 31) group [226.12 vs. 268.57 mg/dL, respectively, (95% CI for difference - 63.195 to - 21.695), p < 0.0001]. Significant differences in mean glucose level were noted at fasting [170.96 vs. 221.13 mg/dL, respectively, (95% CI for difference - 72.70 to - 27.63), p < 0.0001] and pre-lunch [208 vs. 266.48 mg/dL, respectively, (95% CI for difference - 86.61 to - 30.36), p < 0.0001]. CONCLUSION: In hospitalized patients with diabetes receiving corticosteroids, an NPH insulin-based protocol improves glycemic control. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT01970241.

RESUMEN

AIM: To compare the safety and efficacy or 3 basal-bolus regimens of neutral protamine hagedorn (NPH)/regular insulin in the management of inpatient hyperglycemia. METHODS: We randomized 105 patients with blood glucose levels between 140 and 400 mg/dL to a basal-bolus regimen of NPH insulin given once (n = 30), twice (n = 40) or three times (n = 35) daily, in addition to pre-meal regular insulin. Major outcomes included were differences in glycemic control, frequency of hypoglycemia and total insulin dose. RESULTS: NPH insulin given in a once-daily regimen was associated with better glycemic control (58.3%) compared to twice daily (42.4%) and three times daily (48.9) regimens (P = 0.031). The frequency of hypoglycemia was similar between the three groups (2.0%, 0.7% and 1.2%, P = 0.21). The mean insulin dose at discharge was 0.48 ± 0.14 U/kg in the once-daily group compared to 0.69 ± 0.28 in the twice-daily, and 0.65 ± 0.20 in the three times daily regimens (P < 0.001). CONCLUSION: NPH insulin administered in a once-daily regimen resulted in improvement in glycemic control with similar rates of hypoglycemia compared to a twice-daily and a three times-daily regimen. Further studies are needed to evaluate whether this regimen could be implemented in all hospitalized patients with hyperglycemia.

RESUMEN

AIMS: Evaluate efficacy and hypoglycaemia according to concomitant oral antidiabetes drug (OAD) in people with type 2 diabetes initiating insulin glargine 100U/mL (Gla-100) or neutral protamine Hagedorn (NPH) insulin once daily. METHODS: Four studies (target fasting plasma glucose [FPG] ⩽100mg/dL [⩽5.6mmol/L]; duration ⩾24weeks) were included. Standardised data from 2091 subjects (Gla-100, n=1024; NPH insulin, n=1067) were analysed. Endpoints included glycated haemoglobin (HbA1c) and FPG change, glycaemic target achievement, hypoglycaemia, weight change, and insulin dose. RESULTS: Mean HbA1c and FPG reductions were similar with Gla-100 and NPH insulin regardless of concomitant OAD (P=0.184 and P=0.553, respectively) and similar proportions of subjects achieved HbA1c <7.0% (P=0.603). There was a trend for more subjects treated with Gla-100 achieving FPG ⩽100mg/dL versus NPH insulin (relative risk [RR] 1.09 [95% confidence interval (CI) 0.97-1.23]; P=0.135). Plasma glucose confirmed (<70mg/dL) overall and nocturnal hypoglycaemia incidences and rates were lower with Gla-100 versus NPH insulin (overall RR 0.93 [95% CI 0.87-1.00]; P=0.041; nocturnal RR 0.73 [95% CI 0.65-0.83]; P<0.001). After 24weeks, weight gain and insulin doses were higher with Gla-100 versus NPH insulin (2.7kg vs 2.3kg, P=0.009 and 0.42U/kg vs 0.39U/kg; P=0.003, respectively). Insulin doses were higher when either insulin was added to sulfonylurea alone. CONCLUSIONS: Pooled results from treat-to-target trials in insulin-naïve people with type 2 diabetes demonstrate a significantly lower overall and nocturnal hypoglycaemia risk across different plasma glucose definitions with Gla-100 versus NPH insulin at similar glycaemic control. OAD therapy co-administered with Gla-100 or NPH insulin impacts glycaemic control and overall nocturnal hypoglycaemia risk.

RESUMEN

AIM: To explore the clinical safety and effectiveness of insulin detemir (IDet) in a subgroup of Indian patients with type 2 diabetes (T2D) switched from either insulin glargine (IGlar) or neutral protamine Hagedorn (NPH) insulin in the 24-week, non-interventional A1chieve study. MATERIALS AND METHODS: Indian patients with T2D switching from pre-study IGlaror NPH insulin to IDet were included. Safety and effectiveness outcomes were evaluated by the physicians in local clinical settings. RESULTS: A total of 102 patients switched from IGlar to IDet (GLA group) and 39 patients switched from NPH insulin to IDet (NEU group). At baseline, the mean glycated hemoglobin A1c (HbA1c) levels were 9.9 ± 1.8% in the GLA group and 9.1 ± 1.2% in the NEU group. No serious adverse drug reactions, serious adverse events, or major hypoglycemic events were reported in either group throughout the study. At baseline and Week 24, 11.8% and 7.5% of patients, respectively, reported overall hypoglycemic events in the GLA group. No hypoglycemic events were reported at Week 24 in the NEU group. At Week 24, the mean HbA1c levels were 7.6 ± 0.9% in the GLA group and 7.3 ± 0.7% in the NEU group. The mean fasting plasma glucose, postprandial plasma glucose and quality of life also appeared to improve over 24 weeks. CONCLUSION: Switching to IDet therapy from IGlar and NPH insulin was well-tolerated and appeared to be associated with improved glycogenic control in Indian patients.

RESUMEN

OBJECTIVES: To construct a clinical management matrix using serial fetal abdominal circumference measurements (ACMs) that will predict normal birth weight in pregnancies complicated by gestational diabetes (GDM) and reduce unnecessary ultrasound examination in women with GDM. STUDY DESIGN: Retrospective cohort study of 144 women with GDM in a specialist obstetric-diabetes clinic. Women with GDM who delivered singleton infants were identified from a clinical register. Regression analysis was used to identify associations between serial ACMs, maternal parameters and normal birth weight (birth weight between the 10th and 90th percentiles). Predictive clinical models were designed with the aim of identifying normal birth weight infants with the lowest number of fetal ultrasound scans. RESULTS: Compared to mothers of large-for-gestational-age (LGA) infants, mothers of normal weight infants had lower fasting glucose measurements at diagnosis (5.9 mmol/l±1.0 vs. 6.6 mmol/l±0.7, p<0.05), lower maternal weight at delivery (90 kg±17 vs. 96 kg±17, p<0.05), and a lower rate of prior LGA infants (31% vs. 60%, p<0.05). Maternal weight and a history of prior LGA delivery were identified as useful predictors of fetal birth weight in predictive models. Serial ACMs below the 50th, 75th and 90th percentiles could predict normal birth weight with 100%, 97% and 96% positive predictive value respectively when used in these risk factor based models. Two measurements sufficed in low-risk pregnancies. CONCLUSION: Serial ACMs can predict normal birth weight in GDM.

RESUMEN

UNLABELLED: Aims/Introduction: The aim of the present study was to evaluate the efficacy of replacing neutral protamine Hagedorn insulin (NPH) with the long-acting insulin analogue, detemir, in clinical practice. MATERIALS AND METHODS: We carried out a retrospective study to compare the effects of replacing NPH with detemir in basal-bolus insulin therapy in Japanese patients with type 1 diabetes. A total of 19 patients were enrolled in the study, and changes in hemoglobin A1c (HbA1c), insulin dose, bodyweight, fasting blood glucose levels (FBG), within-patient variability in FBG and prevalence in hypoglycemia were monitored for 12 weeks before replacement and during three periods after replacement; 1-12 weeks (period 1), 13-24 weeks (period 2) and 25-36 weeks (period 3). RESULTS: HbA1c values improved significantly in periods 2 and 3. Despite the total insulin dose remaining unchanged throughout the study, the basal insulin dose increased from 0.24 to 0.27 IU/kg/day in period 2 and 0.28 IU/kg/day in period 3. Bodyweight decreased from 61.8 to 60.8 kg in period 1, whereas FBG improved throughout the study. Within-patient variability in FBG was lower with detemir treatment than with NPH, despite the number of hypoglycemic episodes increasing significantly after replacement. CONCLUSIONS: These findings show that the weight loss observed in patients was independent of the reduction in calorie intake resulting from less frequent hypoglycemic attacks. In Japanese patients with diabetes who received NPH, replacing NPH with detemir led to improvements in glycemic control without any weight gain.
