Scheduled Subcutaneous Insulin therapy has been recommended for better glycemic control. Aims: To compare efficacy and safety of traditional sliding scale insulin (SSI) versus modified 70/30 insulin versus basal plus supplemental scale (SS) insulin regimens for glycemic control of inpatients with diabetes. Methods: In a prospective trial, 62 patients with diabetes were randomized to receive either hospital SSI (N = 22), or twice daily 70/30 insulin plus supplemental lunchtime insulin for BG ≥ 150 mg/dL (N = 21) or once every night glargine plus prandial glulisine for BG ≥ 150 mg/dL (N = 19). 70/30 insulin and glargine were started respectively at 0.4 and 0.2 U/kg/day for BG ≤ 200 mg/dL or 0.5 and 0.3 U/kg/day for BG above 200 mg/dL. Results: Starting at BG level of 204 ± 68, 200 ± 50 and 241 ± 94 mg/dL in SSI, 70/30 insulin and glargine/glulisine groups respectively, (F(2,35.47) = 1.467, p = 0.244, Welch test), mean daily BG after first day of hospitalization was statistically significant (F(2,35.58) = 7.043, p = 0.003, Welch test) lower in 70/30 insulin group (171 ± 38 mg/dL) compared to (218 ± 71 mg/dL) in SSI group (p = 0.026) and (225 ± 65 mg/dL) in glargine/glulisine group (p = 0.01). Conclusions: With poorly educated nursing staff, basal plus SS insulin failed to provide adequate glycemic control. However, tailored 70/30 insulin regimen resulted in statistically significant glycemic control compared to traditional SSI.展开更多

We hypothesized that insulin concentrations determined during the last four hours of a 24 hour period would be greater when identical doses of insulin glargine were administered twice-daily as compared to once-daily among type 1 diabetes patients. Research Methods: Ten subjects with insulin deficient type 1 diabetes were admitted for two 38-hour studies at least one week apart. Patients received full-dose insulin glargine once daily at 0800 and half-dose insulin glargine twice-daily at 0800 and 2000 for at least one week in random order prior to overnight studies. Overnight glucose was stabilized with intravenous insulin on the evening prior to study, and subjects fasted and did not receive short acting insulin during the study period. Insulin concentrations were assessed every 30 minutes with an ultrasensitive assay between study hours 20 and 24. Results: Insulin concentrations for the final four hours of study period did not differ between once-daily and twice-daily insulin glargine administration (p = 0.38). Home glucose testing results and overnight plasma glucose concentrations did not differ between study conditions. Conclusions: These results demonstrate that insulin concentrations are equivalent during the last four hours of a 24-hour period when insulin glargine is administered once- or twice-daily. These findings do not support a role for twice-daily insulin glargine in the management of patients with type 1 diabetes.展开更多

Methods: Patients with T2DM, who had previously received insulin injection therapy and who had had their treatment switched to BPT (liraglutide), were retrospectively recruited. The efficacy of BPT was assessed by determining changes in HbA1c, body weight and total daily insulin dose from baseline to 4 months after BPT initiation. Safety was assessed by comparing the frequency of hypoglycemic episodes at baseline and after 4 months. The Wilcoxon test was used to analyze changes in parameters throughout the study period. Results: Twenty-nine patients, previously treated with basal-supported oral therapy (BOT), basal-bolus insulin, or pre-mixed insulin, were recruited. When analyzed together, there was no change in HbA1c throughout the study period, but body weight decreased (baseline 68.8 ± 13.2 kg vs. month 4 67.3 ± 13.1 kg;p < 0.001). Total daily insulin dose decreased after 4 months (baseline 24.4 ± 15.5 U/day vs. month 4 14.7 ± 9.2 U/day;p < 0.001), and there was no change in the frequency of hypoglycemic episodes. Analysis was conducted within sub-groups based on previous treatment modality. In the BOT group, HbA1c decreased from baseline after 2 months and body weight did not change throughout the study period. In both the basal-bolus insulin group and the pre-mixed insulin group, HbA1c remained steady throughout and there was a decrease in body weight. No change in the frequency of hypoglycemia was observed in any of the sub-groups. Conclusion: BPT in T2DM was associated with weight loss without changes in glycemic control over 4 months, suggesting that it may be an effective and safe therapy.展开更多

Type 2 diabetes mellitus (T2DM) is currently a high-burden disease in Nepal with a prevalence of 8.4%. Of these 8% - 18% patients are on insulin and 42% patients were reported to have uncontrolled diabetes in the past year. This suggests a need for better therapy options in terms of efficacy and safety. The current study was designed to investigate the effects of Insulin glargine-based therapy in Nepalese with T2DM who could not achieve adequate glycemic control with oral and non-glargine-insulin therapy. Methods: This is a prospective, multi-centric, single arm and post marketing observational study to assess the safety and effectiveness of Glaritus®(Wockhardt’s Insulin Glargine) in 52 T2DM patients from 3 (three) different study sites in Nepal (Bharatpur, Kathmandu and Pokhra) from September 2015 to December 2016. The primary objective of the study was to evaluate the safety of Glaritus®, mainly in terms of hypoglycemia, renal function tests and liver function tests. The secondary objectives were to evaluate the effectiveness of Glaritus®in terms of percentage of patients achieving HbA1c goal of less than 7%, mean changes in HbA1c & fasting plasma glucose (FPG) levels from baseline till the end of study. Results: 3.85% of subjects experienced hypoglycemia during first 3 months of therapy whereas 1.92% had similar experience in next 3 months of therapy. The mean HbA1c values reduced from 9.16% to 7.15% at the end of study. 21.05% of the enrolled subjects achieved the goal of HbA1c ®was well tolerated by the study patients. Conclusion: In patients with type 2 diabetes mellitus inadequately controlled on oral hypoglycemic agents and/or insulin, initiation with Glaritus®significantly improved glycemic control with good tolerability and acceptability. This analysis in T2DM Nepalese patients shows that by significantly improving glycemic control while not increasing risk of hypoglycemia, Glaritus®provides safer basal insulin and may be suited to aggressive treatment regimens. From a societal perspective, it will help more patients reach the glycemic control target as recommended by the current treatment guidelines.展开更多

Methods: 5-point capillary blood glucose was moni- tored in pre- and post-CSII and the insulin dose which could stabilize blood glucose was defined as the total daily dose of insulin, including basal and bolus total dose. Correlation between HbA1c level and total daily dose of insulin in patients with type 2 dia- betes mellitus was analyzed. Correlation between HbA1c level and 5-point capillary blood glucose was also analyzed. Results: Obvious correlation was observed between HbA1c level and the basal total daily dose of insulin if HbA1c was more than 9.3% (r=0.635, P<0.05). The average of 5-point capillary blood glucose was best correlated with HbA1c and fasting blood glucose next best. Conclusion: HbA1c level can forecast basal total daily dose of insulin in CSII.展开更多
