Assessment of Alimentación Normal con Ajuste de Insulina (ANAIS), a Spanish version of the DAFNE programme, in people with Type 1 diabetes: a randomized controlled parallel trial.

AIM: To evaluate the effects of Alimentación Normal con Ajuste de Insulina (ANAIS), a group-based, therapeutic education programme for Type 1 diabetes based on a flexible insulin regimen adjusted to the individual's food intake. METHODS: Participants with Type 1 diabetes and HbA1c levels of 53-86 mmol/mol (7-10%) were recruited from outpatient clinics at a tertiary care centre. They were randomized (using opaque, sealed envelopes, with a 2:1 treatment allocation ratio) to attend the training course immediately (immediate ANAIS; intervention group) or a year later (delayed ANAIS; control group). The main outcome was HbA1c level at 1 year. Secondary outcomes included lipid levels, weight, hypoglycaemic events, insulin dose, treatment satisfaction, self-perceived dietary freedom, quality of life and participant-defined goals. RESULTS: A total of 48 participants were assigned to the intervention group and 32 to the control group. Twelve months after completing the training, adjusted HbA1c was not significantly different in the intervention group [64 ± 1.3 vs 68 ± 1.6 mmol/mol (8.0 ±0.1% vs 8.4 ±0.1%); P=0.081]. Treatment satisfaction was significantly higher in the intervention group, but no differences were found in hypoglycaemic events, weight, insulin dose or changes in dietary freedom. At 1 year after the intervention, 72% of the participants (vs 33% in the control group; P=0.046) reported exceeding their expectations regarding achievement of their main personal goal. CONCLUSION: Promoting dietary freedom and empowering people with Type 1 diabetes through structured education programmes, such as ANAIS, improves treatment satisfaction and self-defined goals. No significant improvement in HbA1c level was achieved.

Effect of liraglutide on physical performance in type 2 diabetes: Results of a randomized, double-blind, controlled trial (LIPER2).

AIMS: To assess the effect of the GLP-1 analogue liraglutide on measures of cardiac function and physical performance in patients with type 2 diabetes (T2D). METHODS: In this phase-IV randomized double-blind placebo-controlled parallel-group clinical trial at a tertiary hospital, T2D patients with HbA1c levels of 7-10% with oral agents and/or intermediate-/long-acting insulin were allocated (computer-generated randomization, ratio 1:1) to either liraglutide 1.8 mg/day or a placebo for 6 months. The primary endpoint was maximum oxygen consumption (VO2max) during cycle ergometry, while other procedures included a 6-min walk test, echocardiography, anthropometry and blood tests. Safety endpoints were also monitored, and an intention-to-treat analysis was performed. RESULTS: A total of 24 patients (15 women) aged 52 (11.7) years, with diabetes duration of 8.7 (5.8) years, BMI 34.98 (6.2) kg/m2 and HbA1c 8.2% (0.68%), were randomized to liraglutide 1.8 mg daily or placebo. There were no differences in VO2max [17.98 (4.8) vs. 15.90 (4.96) mL/kg/min; P > 0.10], VE/VCO2 slope [30.18 (4.8) vs. 32 (4.49)], left ventricular ejection fraction or 6-min walk test [530.7 (86) vs. 503.9 (84) m] at 6 months. HbA1c was lower (6.7% vs. 7.7%; P = 0.005), with a trend towards lower maximum systolic blood pressure during ergometry [171.7 (24.4) vs. 192.5 (25.6); P = 0.052] in the liraglutide group at the end of the study. There were no severe adverse events. CONCLUSION: In this trial, liraglutide improved glycaemic control in T2D, but had no significant effects on either physical performance or myocardial function.

[Effectiveness of treatment with metformin in patients with type 2 diabetes mellitus poorly controlled with insulin treatment]. / Eficacia del tratamiento con metformina en pacientes con diabetes mellitus tipo 2 pobremente controlada con insulinoterapia.

Combined treatment with insulin plus metformin could be a good alternative to improve the glycemic control in patients with type 2 diabetes mellitus poorly controlled with insulin therapy. We retrospectively studied 21 obese insulin-treated type 2 diabetic patients with deficient metabolic control (HbA1c 9.2 +/- 1.2%) who were treated with metformin for a minimum of 8 months. After 4 months of treatment, a significant decrease in the percentage of HbA1c was observed (delta HbA1c -1.07 +/- 1.12%; p < 0.01), with maintained values since then. Non changes in body weight or insulin requirement were noted. Our results suggest that the addition of metformin to insulin treatment is a safe and effective strategy for the improvement of glycemic control among obese type 2 diabetic patients.
