Comparison of additional metformin or NPH insulin to mealtime insulin lispro therapy with mealtime human insulin therapy in secondary OAD failure

DIABETES OBESITY & METABOLISM, Issue 6 2003

Aim:, It has been found that non-fasting plasma glucose is a better marker of diabetic control than fasting plasma glucose in type 2 diabetes. The main aim of treatment of type 2 diabetic patients is to control plasma glucose and HbA1c levels. In this study, we aimed to assess the effects of three different insulin regimens (group I: lispro insulin + NPH insulin, group II: lispro insulin + metformin and group III: regular insulin + NPH insulin) on overall glycaemic control and metabolic parameters in type 2 diabetic patients with secondary oral anti-diabetic drug failure. Methods:, Sixty type 2 diabetic patients with secondary OAD failure were randomly allocated into three different treatment groups equally. There were no significant differences between groups concerning age, body mass index, diabetes duration, HbA1c and serum lipid levels at the beginning of the study. During the 6-month treatment period, blood glucose levels were determined 10 times during 24 h at pre-meal, post-prandial 1 and 2 h and at bedtime. Results:, Group I was found to be the most effective treatment regimen in controlling HbA1c levels (group I vs. group II, p = 0.013; group I vs. group III, p = 0.001; group II vs. group III, p > 0.05). When the comparison was made in each group, change in HbA1c was statistically significant for all groups (,3.18%, p = 0.001; ,2.02%, p = 0.043 and ,2.66%, p = 0.008 respectively). Group I was found to be more effective in controlling fasting and post-prandial plasma glucose levels measured at all times during the day when compared with group II and group III. In group II triglyceride levels were found to be significantly reduced, whereas other groups had no effect on lipids. No serious hypoglycaemic episodes were observed in any of the cases, whereas in group I hypoglycaemic episode rates were increased (,2 = 8.843, p = 0.012). Conclusions:, Lispro insulin plus NPH insulin regimen is more effective in controlling both pre- and post-prandial glucose levels and HbA1c when compared to regular insulin plus NPH insulin combination. Mealtime lispro insulin plus metformin combination therapy should also be seriously considered as an effective and alternative treatment regimen. It is worthy of attention that insulin lispro plus metformin lowered triglyceride levels. [source]

Efficacy and tolerance of intranasal insulin administered during 4 months in severely hyperglycaemic Type 2 diabetic patients with oral drug failure: a cross-over study

Abstract Aims We have evaluated the local tolerance and the metabolic efficacy of a lyophilized nasal insulin preparation in 10 severely hyperglycaemic Type 2 diabetic patients. Methods The study included two 4-month randomized periods: (A) three preprandial doses of nasal insulin secondarily combined with one evening subcutaneous NPH if the desired glycaemic control was not achieved; (B) two NPH injections daily. We assessed: (i) diabetes control on monthly HbA1c levels and occurrence of hypoglycaemic events; (ii) local tolerance on clinical symptoms, rhinoscopy, nasal muco-ciliary clearance and nasal biopsies; (iii) insulin absorption at months 0 and 4. Results One patient was withdrawn because of cough and dizziness after each nasal application. HbA1c was not significantly different at month 4 (9.4 ± 0.5% vs. 8.8 ± 0.2%, A vs. B). Blood glucose control remained only fair in the majority of our patients. Nasal insulin was able to replace the daytime fraction of the subcutaneous insulin with a 18% efficacy. Side-effects included transient nasal hyperactivity (pruritis, sneezing and rhinorrhoea) and chronic persistence of nasal crusts. Plasma insulin profiles were not significantly different between months 0 and 4. Conclusions The utilization of nasal insulin (with or without NPH) was associated with similar diabetes control compared with NPH twice daily. Nasal insulin alone was able to achieve an adequate glycaemic control in three of the 10 patients. Diabet. Med. 18, 614,618 (2001) [source]

Remission of epilepsy after two drug failures in children: A prospective study,

ANNALS OF NEUROLOGY, Issue 5 2009
Anne T. Berg PhD
Objective Determine the probability of a more than 1-year remission after failure of a second drug in children prospectively followed from initial diagnosis of epilepsy and then from time of second drug failure. Identify prognostic factors for remission after second drug failure. Methods Of 613 children, 128 did not respond favorably to 2 drugs, had a trial of at least a third drug (median, 3), and were followed for more than 1 year (median, 10.1 years) since second drug failure. Product limit and proportional hazards techniques were used to analyze predictors of any 1-year remission (Rem1) and 1- and 3-year remission at last contact (Rem1/3-LC). Results Seventy-three patients (57%) had a remission. Repeated remissions and relapses were common. Only 48 (37.5%) achieved Rem1-LC and 28 (23%) Rem3-LC. Idiopathic epilepsy (Rem1: rate ratio [RR], 3.64, p < 0.0001; Rem1-LC: RR, 2.57, p = 0.008) and seizure frequency (Rem1: RR, 0.76, p = 0.003; Rem1-LC: RR, 0.82, p = 0.04 per increase in category) were the most robust predictors. Symptomatic cause was the only correlate of Rem3-LC. Remission before second drug failure did not predict remission after second drug failure. Interpretation Remission after second drug failure is common but often temporary. Children who have not responded to two appropriate drugs should be carefully evaluated to maximize therapy and possibly considered for more aggressive treatments. Ann Neurol 2009;65:510,519 [source]
