Background Liraglutide 3·0 mg was shown to reduce bodyweight and improve glucose metabolism after the 56-week period of this trial, one of four trials in the SCALE programme. In the 3-year assessment of the SCALE Obesity and Prediabetes trial we aimed to evaluate the proportion of individuals with prediabetes who were diagnosed with type 2 diabetes. Methods In this randomised, double-blind, placebo-controlled trial, adults with prediabetes and a body-mass index of at least 30 kg/m2, or at least 27 kg/m2 with comorbidities, were randomised 2:1, using a telephone or web-based system, to once-daily subcutaneous liraglutide 3·0 mg or matched placebo, as an adjunct to a reduced-calorie diet and increased physical activity. Time to diabetes onset by 160 weeks was the primary outcome, evaluated in all randomised treated individuals with at least one post-baseline assessment. The trial was conducted at 191 clinical research sites in 27 countries and is registered with ClinicalTrials.gov, number NCT01272219. Findings The study ran between June 1, 2011, and March 2, 2015. We randomly assigned 2254 patients to receive liraglutide (n=1505) or placebo (n=749). 1128 (50%) participants completed the study up to week 160, after withdrawal of 714 (47%) participants in the liraglutide group and 412 (55%) participants in the placebo group. By week 160, 26 (2%) of 1472 individuals in the liraglutide group versus 46 (6%) of 738 in the placebo group were diagnosed with diabetes while on treatment. The mean time from randomisation to diagnosis was 99 (SD 47) weeks for the 26 individuals in the liraglutide group versus 87 (47) weeks for the 46 individuals in the placebo group. Taking the different diagnosis frequencies between the treatment groups into account, the time to onset of diabetes over 160 weeks among all randomised individuals was 2·7 times longer with liraglutide than with placebo (95% CI 1·9 to 3·9, p<0·0001), corresponding with a hazard ratio of 0·21 (95% CI 0·13–0·34). Liraglutide induced greater weight loss than placebo at week 160 (–6·1 [SD 7·3] vs −1·9% [6·3]; estimated treatment difference −4·3%, 95% CI −4·9 to −3·7, p<0·0001). Serious adverse events were reported by 227 (15%) of 1501 randomised treated individuals in the liraglutide group versus 96 (13%) of 747 individuals in the placebo group. Interpretation In this trial, we provide results for 3 years of treatment, with the limitation that withdrawn individuals were not followed up after discontinuation. Liraglutide 3·0 mg might provide health benefits in terms of reduced risk of diabetes in individuals with obesity and prediabetes. Funding Novo Nordisk, Denmark
Summary Aims: To evaluate the efficacy and safety of alogliptin, a new dipeptidyl peptidase‐4 inhibitor, for 26 weeks at once‐daily doses of 12.5 and 25 mg in combination with metformin in patients whose HbA1c levels were inadequately controlled on metformin alone. Methods and patients: Patients with type 2 diabetes and inadequate glycaemic control (HbA1c 7.0‐10.0%) were randomised to continue a stable daily metformin dose regimen (≥ 1500 mg) plus the addition of placebo (n = 104) or alogliptin at once‐daily doses of 12.5 (n = 213) or 25 mg (n = 210). HbA1c, insulin, proinsulin, C‐peptide and fasting plasma glucose (FPG) concentrations were determined over a period of 26 weeks. Results: Alogliptin at either dose produced least squares mean (SE) decreases from baseline in HbA1c of −0.6 (0.1)% and in FPG of −17.0 (2.5) mg/dl [−1.0 (0.1) mmol/l], decreases that were significantly (p < 0.001) greater than those observed with placebo. The between treatment differences (alogliptin – placebo) in FPG reached statistical significance (p < 0.001) as early as week 1 and persisted for the duration of the study. Overall, adverse events (AEs) observed with alogliptin were not substantially different from those observed with placebo. This includes low event rates for gastrointestinal side effects and hypoglycaemic episodes. There was no dose‐related pattern of AE reporting between alogliptin groups and few serious AEs were reported. Conclusion: Alogliptin is an effective and safe treatment for type 2 diabetes when added to metformin for patients not sufficiently controlled on metformin monotherapy.
BackgroundWe have previously shown that many chronic, inflammatory diseases are accompanied, and possibly partly caused or exacerbated, by various coagulopathies, manifested as anomalous clots in the form of ‘dense matted deposits’. More recently, we have shown that these clots can be amyloid in nature, and that the plasma of healthy controls can be induced to form such clots by the addition of tiny amounts of bacterial lipopolysaccharide or lipoteichoic acid. Type 2 diabetes (T2D) is also accompanied by raised levels of LPS.MethodsWe use superresolution and confocal microscopies to investigate the amyloid nature of clots from healthy and T2D individuals.ResultsWe show here, with the established stain thioflavin T and the novel stains Amytracker™ 480 and 680, that the clotting of plasma from type 2 diabetics is also amyloid in nature, and that this may be prevented by the addition of suitable concentrations of LPS-binding protein.ConclusionThis implies strongly that there is indeed a microbial component to the development of type 2 diabetes, and suggests that LBP might be used as treatment for it and its sequelae.
We retrospectively reviewed the presentation and management of children with primary hyperparathyroidism (PHPT) from 1973 to 1995 at a paediatric tertiary-care centre. There were 11 patients (6 females), aged 12.3-17.7 years at presentation, with sporadic PHPT confirmed by histopathology (single adenoma). Presentation consisted of renal colic, or non-specific gastrointestinal, musculoskeletal or neurological symptoms. Misdiagnosis was common until hypercalcaemia was identified, 0.5-24 months after onset of symptoms (mean 7.7 months). All patients had hypercalcaemia and low-normal serum phosphate. The parathyroid hormone (PTH) radioimmunoassay used before 1986 was elevated in 1/4 patients; the intact PTH assay used after 1986 was elevated in 7/7 patients. At presentation, six had end-organ damage: band keratopathy, renal lesions, and/or bone disease. Preoperative localization was accurate in 0/4 patients diagnosed before 1986, but 5/7 patients diagnosed after 1986: three by ultrasound or sestamibi scan alone, and two by ultrasound and technetium scan. Surgical outcome was not dependent upon the accuracy of pre-operative localization. PHPT is rare in children but usually associated with end-organ damage, presumably due to delayed diagnosis. It should be considered in the differential diagnosis of unexplained non-specific complaints. The intact PTH assay greatly assists pre-operative diagnosis. The usefulness of pre-operative localization requires further research.
Insulin glulisine (glulisine), a human insulin analogue with a rapid-acting time-action profile, has been developed to fulfil the mealtime (bolus) insulin requirement in patients with diabetes. The aim of this multinational, multi-centre, controlled, open-label, randomized, parallel-group study was to compare the efficacy and safety of insulin glulisine (glulisine) to that of insulin lispro (lispro) in adults diagnosed with Type 1 diabetes. Of the 683 patients randomized, 672 received treatment (339 patients received glulisine, 333 patients received lispro). Over the 26-week study, a similar reduction in mean HbA1c occurred in both groups (adjusted mean change from baseline -0.14% in both groups). The basal insulin dose was relatively unchanged from baseline in the glulisine group but increased in the lispro group (glulisine: 0.12 IU vs. lispro: 1.82 IU; p = 0.0001). As a consequence, total daily insulin dose decreased in the glulisine group but increased in the lispro group (glulisine: -0.86 IU vs. lispro: 1.01 IU; p = 0.0123). There was no relevant difference between the two groups in the reporting of symptomatic hypoglycaemia (overall, nocturnal and severe). This study demonstrates that glulisine provides equivalent glycaemic control to lispro. The clinical relevance of any difference in total daily insulin dose remains to be established.
