RESUMO

AIM: To investigate the effects of once-daily oral semaglutide 50 mg on energy intake, appetite, control of eating and gastric emptying. METHODS: A clinical pharmacology, double-blind study was conducted in 61 adults with obesity randomized to once-daily oral semaglutide (dose-escalated to 50 mg) or placebo for 20 weeks. Energy intake was measured during an ad libitum lunch, and participant-reported appetite ratings and Control of Eating Questionnaire responses were assessed. Gastric emptying was measured using paracetamol absorption following a standardized breakfast. RESULTS: The relative change from baseline in ad libitum energy intake at week 20 (primary endpoint) was -39.2% points (95% confidence interval -59.0%, -19.4%) with semaglutide compared with placebo. Body weight was reduced by 9.8% with semaglutide and by 1.5% with placebo. Semaglutide reduced hunger, increased fullness and satiety, and was associated with fewer food cravings and better control of eating versus placebo. No statistically significant difference in gastric emptying was observed at week 20. CONCLUSIONS: In participants with obesity, once-daily oral semaglutide 50 mg reduced energy intake, body weight and appetite, and improved control of eating. There was no evidence of delayed gastric emptying at week 20, as measured through paracetamol absorption.

RESUMO

BACKGROUND: Weight loss is reported with oral roflumilast, which is approved for chronic obstructive pulmonary disease (COPD). Recently, the drug has shown efficacy in psoriasis, a disease strongly linked to overweight/obesity. OBJECTIVE: To describe the effects of oral roflumilast on body weight and cardio-metabolic parameters in patients with psoriasis. METHODS: Posthoc analyses from the PSORRO study, where patients with moderate-to-severe plaque psoriasis were randomized 1:1 to oral roflumilast 500 µg once-daily or placebo for 12 weeks, followed by active, open-label treatment through week 24 in both groups. Changes in body weight, blood pressure, gastrointestinal symptoms, and laboratory tests were registered. No lifestyle or dietary interventions were applied. RESULTS: Forty-six patients were randomized. Baseline characteristics across groups were comparable; mean weight was 103.6 kg. In patients receiving roflumilast, median weight change was -2.6% and -4% at week 12 and 24, respectively. Corresponding numbers were 0.0% and 1.3% in patients initially allocated to placebo. Reduced appetite was more frequent with active therapy. No changes in blood pressure or laboratory tests were observed. LIMITATIONS: Posthoc analyses and low numbers. CONCLUSION: Oral roflumilast induced weight loss and reduced appetite, which support the growing evidence of roflumilast as an attractive treatment alternative for patients with psoriasis.

RESUMO

OBJECTIVE: Bile acid diarrhoea (BAD) is debilitating yet treatable, but it remains underdiagnosed due to challenging diagnostics. We developed a blood test-based method to guide BAD diagnosis. DESIGN: We included serum from 50 treatment-naive patients with BAD diagnosed by gold standard 75selenium homotaurocholic acid test, 56 feature-matched controls and 37 patients with non-alcoholic fatty liver disease (NAFLD). Metabolomes were generated using mass spectrometry covering 1295 metabolites and compared between groups. Machine learning was used to develop a BAD Diagnostic Score (BDS). RESULTS: Metabolomes of patients with BAD significantly differed from controls and NAFLD. We detected 70 metabolites with a discriminatory performance in the discovery set with an area under receiver-operating curve metric above 0.80. Logistic regression modelling using concentrations of decanoylcarnitine, cholesterol ester (22:5), eicosatrienoic acid, L-alpha-lysophosphatidylinositol (18:0) and phosphatidylethanolamine (O-16:0/18:1) distinguished BAD from controls with a sensitivity of 0.78 (95% CI 0.64 to 0.89) and a specificity of 0.93 (95% CI 0.83 to 0.98). The model was independent of covariates (age, sex, body mass index) and distinguished BAD from NAFLD irrespective of fibrosis stage. BDS outperformed other blood test-based tests (7-alpha-hydroxy-4-cholesten-3-one and fibroblast growth factor 19) currently under development. CONCLUSIONS: BDS derived from serum metabolites in a single-blood sample showed robust identification of patients with BAD with superior specificity and sensitivity compared with current blood test-based diagnostics.

RESUMO

OBJECTIVE: The objective of this study was to assess the association between clinically indicated liraglutide treatment and coronary artery plaque progression during 1-year follow-up in asymptomatic diabetes. METHODS: Patients were divided into a group receiving liraglutide (Lira+) and a group not receiving liraglutide (Lira-). Coronary computed tomography angiography (CCTA) was performed to assess total atheroma volume (TAV) and subtypes of plaque volumes (dense calcium, fibrous, fibrous-fatty, and necrotic core plaque) and the plaque progression during one year follow-up. RESULTS: Fifty-five patients (27%) receiving liraglutide and 149 (73%) how did not were included. Changes in TAV during 1-year of follow-up were similar in the two groups (38 ± 180 (Lira+) vs. -1 ± 160 mm3 (Lira-), P = 0.13). A greater increase in fibrous plaque volume was seen in the Lira + vs. the Lira- group (34 ± 129 vs. -2 ± 101 mm3, P = 0.04). Changes over 1-year in the other plaque subtypes were similar in the two groups. Treatment duration of liraglutide was not associated with changes in TAV. CONCLUSION: In patients with T2D without known prior coronary artery disease, liraglutide treatment was associated with a significant increase in coronary artery fibrous plaque volume during 1-year follow-up.

RESUMO

BACKGROUND: Exercise is recommended to protect physical health among people with severe mental illness and holds the potential to facilitate long-term recovery. An inclusive exercise community provides an opportunity for life skill training and social connectedness and may reduce the experience of loneliness and internalized stigmatization which together may improve personal recovery. Using a pragmatic randomized design, we aim to examine the effectiveness of a gym-based exercise intervention tailored to young adults in antipsychotic treatment (i.e., Vega Exercise Community) compared to usual care. It is hypothesized that the Vega Exercise Community will be superior to usual care for personal recovery at four months. METHODS: The trial will be conducted at four sites in Denmark from which 400 participants, aged 18 to 35 years, who are in current treatment with antipsychotic medications for the management of schizophrenia spectrum or affective disorders, will be recruited. Participants will be randomized (2:1) to Vega Exercise Community or usual care. Vega Exercise Community includes three weekly group-based exercise sessions hosted in commercial functional training centers delivered by certified Vega instructors. After four months, participants in Vega Exercise Community will be randomized (1:1) to minimal versus extended support with regards to sustained physical activity. Data will be collected at baseline, four, six and 12 months. The primary outcome is personal recovery assessed by Questionnaire about the Process of Recovery at four months. Behavioral symptoms, health-related quality of life, metabolic health, and program costs will be evaluated to further determine the effectiveness and cost-effectiveness of the Vega Exercise Community. Finally, the quality of life and physical and mental health of the participants' primary relative will be evaluated. DISCUSSION: The results of this trial may have important implications for health, sustained physical activity, and recovery for individuals in treatment with antipsychotics. Given the pragmatic design, positive results may readily be implemented by mental health care professionals to promote exercise as an integrated part of treatment of severe mental illness. TRIAL REGISTRATION: Clinical Trials.gov (NCT05461885, initial registration June 29th, 2022). WHO Universal Trial Number (UTN): U1111-1271-9928.

RESUMO

AIM: To present an overview of exendin(9-39)NH2 usage as a scientific tool in humans and provide recommendations for dosage and infusion regimes. METHODS: We systematically searched the literature on exendin(9-39)NH2 and included for review 44 clinical studies reporting use of exendin(9-39)NH2 in humans. RESULTS: Exendin(9-39)NH2 binds to the orthosteric binding site of the glucagon-like peptide-1 (GLP-1) receptor with high affinity. The plasma elimination half-life of exendin(9-39)NH2 after intravenous administration is ~30 minutes, requiring ~2.5 hours of constant infusion before steady-state plasma concentrations can be expected. Studies utilizing infusions with exendin(9-39)NH2 in humans have applied varying regimens (priming with a bolus or constant infusion) and dosages (continuous infusion rate range 30-900 pmol/kg/min) with subsequent differences in effects. Administration of exendin(9-39)NH2 in healthy individuals, patients with diabetes, obese patients, and patients who have undergone bariatric surgery significantly increases fasting and postprandial levels of glucose and glucagon, but has inconsistent effects on circulating concentrations of insulin and C-peptide, gastric emptying, appetite sensations, and food intake. Importantly, exendin(9-39)NH2 induces secretion of all L cell products (ie, in addition to GLP-1, also peptide YY, glucagon-like peptide-2, oxyntomodulin, and glicentin) complicating use of exendin(9-39)NH2 as a tool to study the isolated effect of GLP-1. CONCLUSIONS: Exendin(9-39)NH2 is selective for the GLP-1 receptor, with numerous and complex whole-body effects. To obtain GLP-1 receptor blockade in humans, we recommend an initial high-dose infusion, followed by a continuous infusion rate aiming at a ratio of exendin(9-39)NH2 to GLP-1 of 2000:1. Highlights Exendin(9-39)NH2 is a competitive antagonist of the human GLP-1 receptor. Exendin(9-39)NH2 has been used as a tool to delineate human GLP-1 physiology since 1998. Exendin(9-39)NH2 induces secretion of GLP-1 and other L cell products. Reported effects of exendin(9-39)NH2 on insulin levels and food intake are inconsistent. Here, we provide recommendations for the use of exendin(9-39)NH2 in clinical studies.

RESUMO

Since the first glucagon-like peptide 1 (GLP-1) receptor agonist (GLP-1RA) was approved in 2005 (exenatide twice daily) for type 2 diabetes (T2D), the class has developed with newer compounds having more pronounced effects on glycaemic control and body weight. Also, administration regimes have become more convenient with once weekly injections, and recently an oral administration has become available. Large-scale randomized controlled cardiovascular (CV) outcome trials (CVOTs) have shown that GLP-1RA therapy can reduce the risk of CV disease (CVD) in high-risk individuals with T2D. In addition, GLP-1RAs may have renal benefits driven by new-onset macroalbuminuria, although no effect on hard renal endpoints has been found. Subsequently, the place for GLP-1RA therapy has changed over recent years, with most societies endorsing GLP-1RA therapy in patients with established or high risk of CVD independently of glycaemia. Initiation of GLP-1RA therapy can be complex due to differences in efficacy, side effects and safety profiles as well as administration forms within the class. Implementing guideline recommendations into ideal patient selection may be challenging both in specialty and non-specialty settings. To ensure adequate and proactive use of modern glucose-lowering medications in the treatment of T2D, it is essential to recognize patients with high risk or documented CVD. The present review provides an overview of the efficacy and benefits of the currently available GLP-1RA compounds. Furthermore, we review the results from recent large-scale CVOTs in a clinical context and suggest improving the implementation of GLP-1RA therapy across specialties to improve overall patient selection.

RESUMO

The glucose-dependent insulinotropic polypeptide (GIP) fragment GIP(3-30)NH2 is a selective, competitive GIP receptor antagonist, and doses of 800 to 1200 pmol/kg/min inhibit GIP-induced potentiation of glucose-stimulated insulin secretion by >80% in humans. We evaluated the effects of GIP(3-30)NH2 across a wider dose range in eight healthy men undergoing six separate and randomized 10-mmol/L hyperglycaemic clamps (A-F) with concomitant intravenous infusion of GIP (1.5 pmol/kg/min; A-E) or saline (F). Clamps A to E involved double-blinded, infusions of saline (A) and GIP(3-30)NH2 at four rates: 2 (B), 20 (C), 200 (D) and 2000 pmol/kg/min (E), respectively. Mean plasma concentrations of glucose (A-F) and GIP (A-E) were similar. GIP-induced potentiation of glucose-stimulated insulin secretion was reduced by 44 ± 10% and 84 ± 10% during clamps D and E, respectively. Correspondingly, the amounts of glucose required to maintain the clamp during D and E were not different from F. GIP-induced suppression of bone resorption and increase in heart rate were lowered by clamps D and E. In conclusion, GIP(3-30)NH2 provides extensive, dose-dependent inhibition of the GIP receptor in humans, with most pronounced effects of the doses 200 to 2000 pmol/kg/min within the tested range.

RESUMO

AIM: To determine the risk of type 2 diabetes onset associated with accumulated inhaled corticosteroids (ICS) dose during the previous year in patients with chronic obstructive pulmonary disease (COPD). MATERIALS AND METHODS: We conducted a nationwide observational cohort study based on data from patients with COPD between 1 January 2010 and 31 December 2017 extracted from Danish health databases. Patients were followed for 7 years, until death or a type 2 diabetes event. A propensity-matched Cox model and an adjusted Cox proportional hazards model (stratified on body mass index [BMI]) were used to estimate the hazard ratio (HR) for new-onset type 2 diabetes. RESULTS: A total of 50 148 patients with COPD were included, 3566 (7.1%) of whom had a type 2 diabetes event. During the previous year before study entry, 35 368 patients (70.5%) used ICS. The propensity-matched Cox model (N = 33 466) showed an increased risk of type 2 diabetes, which progressed with increasing accumulated ICS dose (low-ICS: HR 1.076, confidence interval [CI] 1.075-1.077, P < .0001; medium-ICS: HR 1.106, CI 1.105-1.108, P < .0001; high-ICS: HR 1.150, CI 1.148-1.151, P < .0001), compared with no ICS use. Results were confirmed in the adjusted Cox analysis on the entire study population, but only for patients with BMI <30 kg/m2 . CONCLUSIONS: In patients with COPD, ICS use was associated with a moderate dose-dependent increase in the occurrence of type 2 diabetes.

RESUMO

Acute and adaptive changes in systemic markers of oxidatively generated nucleic acid modifications (i.e., 8-oxo-7,8-dihydro-2'-deoxyguanosine (8-oxodG) and 8-oxo-7,8-dihydroguanosine (8-oxoGuo)) as well as inflammatory cytokines (i.e., C-reactive protein, interleukin-6, interleukin-10, and tumour necrosis factor alpha), a liver hormone (i.e., fibroblast growth factor 21 (FGF21)), and bone metabolism markers (sclerostin, osteocalcin, C-terminal telopeptide, and N-terminal propeptide of type 1 procollagen) were investigated following a marathon in 20 study participants. Immediate changes were observed in inflammatory cytokines, FGF21, and bone metabolism markers following the marathon. In contrast, no immediate changes in urinary excretion of 8-oxodG and 8-oxoGuo were evident. Four days after the marathon, decreased urinary excretion of 8-oxodG (-2.9 (95% CI -4.8;-1.1) nmol/24 h, P < 0.01) and 8-oxoGuo (-5.8 (95% CI -10.3;-1.3) nmol/24 h, P = 0.02) was observed. The excretion rate of 8-oxodG remained decreased 7 days after the marathon compared to baseline (-2.3 (95%CI -4.3;-0.4) nmol/24 h, P = 0.02), whereas the excretion rate of 8-oxoGuo was normalized. In conclusion marathon participation immediately induced a considerable inflammatory response, but did not increase excretion rates of oxidatively generated nucleic acid modifications. In fact, a delayed decrease in oxidatively generated nucleic acid modifications was observed suggesting adaptive antioxidative effects following exercise.

RESUMO

OBJECTIVE: The aim of this explorative study was to evaluate double-balloon enteroscopy (DBE) as a new tool for collecting mucosal biopsies from well-defined parts of the entire small and large bowel in patients with type 2 diabetes and in matched healthy subjects. MATERIAL AND METHODS: Twelve subjects with type 2 diabetes and 12 body mass index and age-matched healthy subjects underwent anterograde and retrograde DBE under nurse-administered propofol sedation on two separate days. We attempted to collect two mucosal biopsies from every 30 cm from pylorus to rectum. RESULTS: A mean of 21 biopsy sites were sampled in the diabetic group versus 25 in the healthy group. In 4 out of 24 patients (2 [17%] from each group) sampling from the entire gastrointestinal system was possible. Mean depth of maximal insertion (anterograde) was 478 ± 32 cm in patients with type 2 diabetes versus 465 ± 44 cm in healthy subjects (p = 0.81) and with retrograde access 230 ± 36 cm (type 2 diabetes) versus 207 ± 26 cm (healthy subjects). CONCLUSIONS: DBE is a minimally invasive way of collecting fresh biopsies from the entire gastrointestinal tract and, thus provides research and clinical communities with a new possibility to access hitherto unexplored human anatomy and physiology.

RESUMO

CONTEXT: Hyperglucagonemia is observed in individuals with obesity and contributes to the hyperglycemia of patients with type 2 diabetes. Hyperglucagonemia may develop due to steatosis-induced hepatic glucagon resistance resulting in impaired hepatic amino acid turnover and ensuing elevations of circulating glucagonotropic amino acids. OBJECTIVE: We evaluated whether glucagon resistance could be induced in healthy individuals by a hypercaloric diet intervention designed to increase hepatic fat content. METHODS: We recruited 20 healthy male individuals to follow a hypercaloric diet and a sedentary lifestyle for 2 weeks. Amino acid concentrations in response to infusion of glucagon were assessed during a pancreatic clamp with somatostatin and basal insulin. The reversibility of any metabolic changes was assessed 8 weeks after the intervention. Hepatic steatosis was assessed by magnetic resonance spectroscopy. RESULTS: The intervention led to increased hepatic fat content (382% [206%; 705%], P < .01). Glucagon infusion led to a decrease in the concentration of total amino acids on all experimental days, but the percentage change in total amino acids was reduced (-2.5% ± 0.5% vs -0.2% ± 0.7%, P = .015) and the average slope of the decline in the total amino acid concentration was less steep (-2.0 ± 1.2 vs -1.2 ± 0.3 µM/min, P = .016) after the intervention compared to baseline. The changes were normalized at follow-up. CONCLUSION: Our results indicate that short-term unhealthy behavior, which increases hepatic fat content, causes a reversible resistance to the effect of glucagon on amino acid concentrations in healthy individuals, which may explain the hyperglucagonemia associated with obesity and diabetes.

RESUMO

CONTEXT: People with type 1 diabetes (T1D) are at increased risk of thrombosis, however, the underlying mechanisms remain unclear. Hypoglycemia induced at rest can induce coagulation activation, but little is known about the hemostatic effects of exercise-related hypoglycemia in people with T1D. OBJECTIVE: We compared hemostatic profiles of individuals with T1D with healthy controls and explored hemostatic effects of hypoglycemia, induced with or without exercise, in participants with T1D. METHODS: Thrombelastography (TEG) was used for a baseline hemostatic comparison between fifteen men with T1D and matched healthy controls. In addition, the participants with T1D underwent two euglycemic-hypoglycemic clamp days in a randomized, crossover fashion. Hypoglycemia was induced with the participants at rest (Hypo-rest) or during exercise (Hypo-exercise). TEG provides data on the rate of coagulation activation (R-time), the rate of clot formation (K-time, α-Angle), the maximum clot amplitude (MA), the functional fibrinogen contribution to the clot strength (MA-FF) and the fibrinolysis (LY-30). RESULTS: The T1D group exhibited shorter R-time and K-time and a greater α-Angle compared to the controls. During the clamp experiments, Hypo-exercise induced an increased clot strength (MA) with a mean difference from baseline of 2.77 mm [95% confidence interval 2.04; 3.51] accompanied with a decreased fibrinolysis (LY-30) of -0.45 percentage points [-0.60; -0.29]. Hypo-rest resulted in increased functional fibrinogen (MA-FF) of 0.74 mm [0.13; 1.36] along with an increased fibrinolysis (LY-30) of 0.54 percentage points [0.11; 0.98]. CONCLUSION: Individuals with T1D exhibit a hypercoagulable hemostatic profile compared to healthy controls and exercise-related hypoglycemia may increase the susceptibility to thrombosis via both procoagulant and antifibrinolytic effects.

RESUMO

In type 1 diabetes, average life expectancy is reduced by ˃10 years as compared with outside of diabetes. Residual cardiovascular risk defines high cardiovascular event rate despite modern, guideline-recommended standard of care of established risk factors like hypertension, dyslipidaemia, and glycaemic control, and it adds importantly to these lost years of life in type 1 diabetes due to atherosclerotic cardiovascular diseases like myocardial infarction and ischaemic stroke. With a growing understanding of inflammation as an important driver of atherosclerotic cardiovascular disease, residual inflammatory risk is a novel and common risk factor and a promising target for lowering residual cardiovascular risk in type 1 diabetes. Interestingly, the inexpensive anti-inflammatory agent colchicine reduced the risk of major adverse cardiovascular events by 25% in cardiovascular outcome trials in the secondary prevention of atherosclerotic cardiovascular disease. Here, we summarize the role of inflammation as a driver of atherosclerosis and review current evidence linking inflammation and atherosclerotic cardiovascular disease in type 1 diabetes. Also, we provide an overview of the evidence base for targeting residual inflammatory risk with colchicine for lowering residual cardiovascular risk in type 1 diabetes.

RESUMO

Bile acid diarrhea (BAD) is a socially debilitating disease. Typical symptoms include loose stools, urgency, and high stool frequency. Recently, we reported the superior efficacy of the glucagon like-peptide 1 receptor agonist (GLP-1RA) liraglutide (administered subcutaneously once daily) in reducing daily bowel movements compared with the traditionally used bile acid sequestrant colesevelam (considered the standard of care). This has generated proposals of testing longer acting and more potent GLP-1RAs for treating BAD. Here, we present a patient with severe BAD who experienced minimal effect of the once-weekly administered GLP-1RA semaglutide, but total remission of BAD symptoms during treatment with liraglutide.

RESUMO

Bile acid diarrhoea is a socially debilitating disease caused by irritation of the colonic mucosa due to a spillover of bile acids from the small intestine into the colon. Studies estimate a prevalence of 1-2% of the adult population, but many patients never seek help or are misdiagnosed. Bile acid diarrhoea is treated with bile acid sequestrants, however, new research shows superior effect on reported symptoms with the glucagon-like peptide 1 receptor agonist liraglutide.

RESUMO

Background: Diabetes-induced gastrointestinal (GI) symptoms are common but difficult to correctly diagnose and manage. We used multi-segmental magnetic resonance imaging (MRI) to evaluate structural and functional GI parameters in diabetic patients and to study the association with their symptomatic presentation. Methods: Eighty-six participants (46 with diabetes and GI symptoms, 40 healthy controls) underwent baseline and post-meal MRI scans at multiple timepoints. Questionnaires were collected at inclusion and following the scans. Data were collected from the stomach, small bowel, and colon. Associations between symptoms and collected data were explored. Utilizing machine learning, we determined which features differentiated the two groups the most. Key Results: The patient group reported more symptoms at inclusion and during MRI scans. They showed 34% higher stomach volume at baseline, 40% larger small bowel volume, 30% smaller colon volume, and less small bowel motility postprandially. They also showed positive associations between gastric volume and satiety scores, gastric emptying time and reflux scores, and small bowel motility and constipation scores. No differences in gastric emptying were observed. Small bowel volume and motility were used as inputs to a classification tool that separated patients and controls with 76% accuracy. Conclusions: In this work, we studied structural and functional differences between patients with diabetes and GI symptoms and healthy controls and observed differences in stomach, small bowel, and colon volumes, as well as an adynamic small bowel in patients with diabetes and GI symptoms. Associations between recorded parameters and perceived symptoms were also explored and discussed.

RESUMO

BACKGROUND: Non-alcoholic fatty liver disease (NAFLD), and particularly liver fibrosis, has been suggested as a risk factor of chronic kidney disease (CKD). Given that NAFLD affects every fourth person globally, better insight is needed. Our aim was to investigate the association between hepatic fibrosis and CKD in patients with type 2 diabetes and to compare different methods for diagnosing liver fibrosis in this study population. METHODS: Cross-sectional study including patients with type 2 diabetes with CKD stages 3-5 (N = 50) or without CKD (N = 50). CKD was defined as estimated glomerular filtration rate <60 mL/min/1.73 m2 with or without proteinuria. Three methods were used to detect significant liver fibrosis defined as either ≥8 kilopascal measured by transient elastography (FibroScan®), fibrosis-4 (FIB-4) score ≥2.67, or NAFLD fibrosis score (NFS) >0.675. RESULTS: Significant liver fibrosis was found in 38% and 28% of the patients with and without CKD, respectively, using at least one of the three methods. Both FIB-4 score and NFS were significantly higher in patients with CKD (p < 0.0009 and p < 0.0001, respectively), although insignificant after adjustments for age, sex, body mass index, and duration of diabetes. In patients without CKD, a significant association between steatosis and fibrosis was observed (p = 0.0007). CONCLUSION: Our data do not support any strong independent association between liver fibrosis and established CKD as assessed by FibroScan, FIB-4 score, and NFS, respectively.
