ABSTRACT

Obesity is a very common pathology worldwide. Among the management alternatives are glucagon-like peptide-1 (GLP-1) analogues, a hormone secreted mainly by the intestine. Apart from its effects as an incretin, effects on gastrointestinal motility have been described, which seem to be fundamental for its effect on obesity, but also the cause of its most frequent potential adverse effects. There is discussion regarding the large number of case reports in relation to the retention of gastric contents at the time of endoscopy. There is currently insufficient evidence to state categorically that they produce a significant change in gastric emptying. Nevertheless, it is recommended to inquire about the use of these drugs before endoscopic procedures that require sedation and, in the presence of symptoms, to suggest changes in the preparation


La obesidad es una patología muy frecuente a nivel global. Dentro de las alternativas del manejo están los análogos del péptido 1 similar al glucagón (GLP-1), hormona secretada principalmente por el intestino. Aparte de sus efec- tos como incretina, se han descrito efectos sobre la motilidad gastrointestinal, los que parecen ser fundamentales para su efecto sobre la obesidad, pero también los causales de sus potenciales efectos adversos más frecuentes. Existe discusión en relación con la gran cantidad de reportes de casos en relación con la retención de contenido gástrico al momento de una endoscopia. Actualmente no existe evidencia suficiente para afirmar categóricamente que producen un cambio significativo en el vaciamiento gástrico. No obstante, se recomienda indagar sobre el uso de estos fármacos antes de procedimientos endoscópicos que requieran sedación y, ante la presencia de síntomas, sugerir cambios en la preparación.

ABSTRACT

OBJECTIVES@#To explore the effects of somatostatin on the levels of gastrointestinal hormones and clinical outcomes in critically ill infants after gastrointestinal surgery.@*METHODS@#Using a random number table method, critically ill infants after gastrointestinal surgery who were admitted to the Intensive Care Unit of Xuzhou Children's Hospital from June 2019 to June 2021 were randomly divided into an observation group (29 cases) and a control group (30 cases). The control group received routine treatment such as anti-infection and hemostasis after surgery, while the observation group received somatostatin in addition to the routine treatment [3.5 μg/(kg·h) infusion for 7 days]. The levels of serum gastrin (GAS), motilin (MTL), insulin, and glucagon-like peptide-1 (GLP-1) before surgery, on the 3rd day after surgery, and on the 7th day after surgery were compared between the two groups. The recovery progress and incidence of complications after surgery were also compared between the two groups.@*RESULTS@#There was no significant difference in the levels of serum GAS, MTL, insulin, and GLP-1 between the two groups before surgery (P>0.05). On the 3rd and 7th day after surgery, the levels of serum GAS, MTL, insulin, and GLP-1 in the observation group were higher than those in the control group (P<0.05). In the observation group, the levels of GAS, MTL, insulin, and GLP-1 on the 7th day after surgery were higher than those before surgery and on the 3rd day after surgery (P<0.05), and the levels on the 3rd day after surgery were higher than those before surgery (P<0.05). There was no significant difference in the levels of serum GAS, MTL, and insulin before surgery, on the 3rd day after surgery, and on the 7th day after surgery in the control group (P>0.05). The level of GLP-1 on the 7th day after surgery was higher than that before surgery and on the 3rd day after surgery (P<0.05), and the level on the 3rd day after surgery was higher than that before surgery (P<0.05) in the control group. The observation group had shorter first time of anal exhaust, recovery time of bowel sounds, and first time of defecation after surgery compared to the control group (P<0.05). The incidence of complications after surgery in the observation group was lower than that in the control group (10% vs 33%, P<0.05).@*CONCLUSIONS@#Somatostatin can increase the levels of serum GAS, MTL, insulin, and GLP-1 in critically ill infants after gastrointestinal surgery, promote the recovery of gastrointestinal function, and reduce the incidence of postoperative complications.

ABSTRACT

To explore the application value of serum Gal-13, GLP-1 and VEGF in the prevention and guidance of adverse pregnancy outcomes in gestational diabetes (GDM). A retrospective study with case-control method was used to select 1 012 GDM patients from Haikou Maternal and Child Health Hospital from January 2019 to December 2022 as the study objects, and they were divided into poor pregnancy outcome group (n=342) and good pregnancy outcome group (n=670) according to whether they had adverse pregnancy outcomes. The medical records of 521 healthy women with normal glucose metabolism were selected as the control group. Serum Gal-13 and GLP-1 were detected by enzyme-linked immunosorbent assay and VEGF was determined by IAMMGE specific protein analyzer. After comparing the differences of the above factors among the three groups, multivariate logistic regression model was used to analyze the influencing factors of adverse pregnancy outcomes in GDM patients, and ROC curve was drawn to analyze the predictive value of serum Gal-13, GLP-1 and VEGF levels on adverse pregnancy outcomes in GDM patients. The results showed that Fasting blood glucose (FPG), glycosylated hemoglobin (HbA1c) and fasting insulin (FINS) in the adverse pregnancy outcome group were 5.92(4.98, 6.41) mmol/L, 5.32(4.96, 5.47)%, 62.56(49.21,99.50) pmol/L, VEGF was 495.47(389.14, 567.13) ng/L, TSH was 1.48(1.34, 1.58) mIU/L, right ventricular myocardial work index (Tei index) was 0.59(0.45, 0.67), 89 cases of elderly parturients; FPG was 4.45(4.16, 5.03) mmol/L, HbA1c was 5.04(4.86, 5.29)%, FINS was 57.41(46.90, 74.08) pmol/L, VEGF was 405.84(348.02, 462.68) ng/L, TSH was 1.42(1.25, 1.50) mIU/L, Tei index was 0.50(0.47, 0.64), there were 142 cases of old women. In the control group, FPG was 4.33(4.05, 4.75) mmol/L, HbA1c was 5.01(4.13, 5.18)%, FINS was 38.48(36.76, 41.72) pmol/L and VEGF was 302.45(283.14, 336.56) ng/L, TSH was 1.32(1.24, 1.47)mIU/L, Tei index was 0.48(0.39, 0.59), and there were 106 elderly parturiencies. The levels of FPG, HbA1c, FINS, VEGF, TSH and Tei index in the adverse pregnancy outcome group and the good pregnancy outcome group were higher than those in the control group, and the proportion of elderly parturients was higher than that in the control group, and the adverse pregnancy outcome group was higher than that in the good pregnancy outcome group. The differences were statistically significant (H=8.620, P<0.001, H=2.616, P=0.014, H=6.156, P<0.001, H=3.051, P<0.001, H=4.892, P=0.044, χ2=2.548, P=0.045). In the adverse pregnancy outcome group, Gal-13 was 15.27(8.35, 24.45)pg/ml, GLP-1 was 9.27(8.26, 12.35) pmol/L and FT4 was 11.59(9.67, 13.48) pmol/L. In the group with good pregnancy outcome, Gal-13 was 25.34(20.14, 29.73) pg/ml, GLP-1 was 12.38(10.25, 15.63) pmol/L and FT4 was 13.86(10.67, 15.10) pmol/L. In the control group, Gal-13 was 31.21(27.48, 34.45) pg/ml, GLP-1 was 11.34(10.40, 14.37) pmol/L and FT4 was 14.15(10.75, 15.43)pmol/L. The levels of Gal-13, GLP-1 and FT4 in the adverse pregnancy outcome group and the good pregnancy outcome group were significantly lower than those in the control group, and the adverse pregnancy outcome group was lower than that in the good pregnancy outcome group. The differences were statistically significant (H=6.458, P=0.011, H=8.445, P<0.001, H=5.694, P<0.001). The levels of Gal-13 and GLP-1 in normal blood glucose recovery group were higher than those in non-normal blood glucose recovery group, and the levels of VEGF were lower than those in non-normal blood glucose recovery group (P<0.05).In multivariate logistic regression analysis, Gal-13, GLP-1, VEGF, TSH, FT4 and Tei indexes were independent influencing factors for adverse pregnancy outcomes with GDM (P<0.05). ROC curve analysis showed that the AUC of Gal-13, GLP-1 and VEGF alone in predicting adverse pregnancy were 0.779, 0.761 and 0.615, respectively. The value of the combined diagnosis was the highest (AUC=0.912), the sensitivity was 90.1%, and the specificity was 80.0%. In conclusion, Gal-13, GLP-1 and VEGF may be independent influencing factors for adverse pregnancy outcomes in GDM patients, and the combined detection of the three may help to improve the auxiliary diagnostic efficacy for predicting adverse pregnancy outcomes.

ABSTRACT

A raiz do yacon (Smallanthus sonchifolius), em função da rica concentração de fruto-oligossacarídeos, é classificada como prebiótico e tornou-se promissora da obesidade pelo aumento da saciedade. O objetivo deste estudo foi avaliar a inclusão de um produto à base de yacon (PBY) em ratas ovariectomizadas (OVX) no consumo alimentar, na modulação de medidas antropométricas e do imunomarcador da saciedade glucagon-like peptide-1 (GLP-1) em ratas Wistar ovariectomizadas (OVX). Analisou-se o consumo alimentar pela pesagem diária de sobra de dieta, a porcentagem de gordura corporal foi determinada pelo índice de Lee e também foram avaliados o peso, o índice de massa corporal (IMC) e circunferência abdominal. Fragmentos do ceco foram utilizados para imunomarcação de GLP-1, de ratas OVX, após serem alimentadas por 24 semanas com dieta padrão adicionadas ou não de 6% de FOS/inulina/PBY. Observou-se diminuição da circunferência abdominal (p=0,2173) em 3,5%, também houve decréscimo de IMC (p=0,3822) em 6,25% e de percentual de gordura corporal (p=0,3528) em 2,14% em animais que receberam PBY durante 24 semanas (G4) comparado aos animais do grupo controle. No grupo G4 o GLP-1 aumentou (p<.0001), os animais aumentaram o consumo (p=0,0064) e, paradoxalmente, tiveram menor ganho de peso (p<.0001), o que pode estar associado ao fato de que as fibras diminuem a eficiência de absorção de lipídeos ao longo do intestino delgado, o que pode diminuir a assimilação calórica de nutrientes. Esse fenômeno demonstra que o PBY possui potencial na modulação da obesidade, portanto, melhoria da qualidade de vida de mulheres na menopausa.(AU)


The yacon root (Smallanthus sonchifolius), due to the rich concentration of fructo-oligosaccharides, is classified as prebiotic and has become promising for obesity due to increased satiety. The aim of this study was to evaluate the inclusion of a yacon-based product (PBY) in ovariectomized rats (OVX) in food consumption, in the modulation of anthropometric measurements and in the satiety immunosorbent glucagon-like peptide-1 (GLP-1) in rats Wistar ovariectomized (OVX). Food consumption was analyzed by daily weighing of leftover diet, the percentage of body fat was determined by the Lee index, and weight, body mass index (BMI) and waist circumference were also evaluated. Cecum fragments were used for immunostaining GLP-1, from OVX rats, after being fed for 24 weeks with a standard diet with or without 6% FOS / inulin / PBY. There was a decrease in abdominal circumference (p = 0.2173) in 3.5%, there was also a decrease in BMI (p = 0.3822) in 6.25% and a percentage of body fat (p = 0.3528) 2.14% in animals that received PBY for 24 weeks (G4) compared to animals in the control group. In the G4 group GLP-1 increased (p <.0001), the animals increased their consumption (p = 0.0064) and paradoxically, they gained less weight gain (p <.0001), which may be associated with the fact that fibers decrease the efficiency of absorption of lipids along the small intestine, which can decrease the caloric assimilation of nutrients. This phenomenon demonstrates that PBY has the potential to modulate obesity, thus improving the quality of life of women in menopause. (AU)

ABSTRACT

ABSTRACT Introduction: The wide net of physiological issues involved in metabolic surgery is extremely complex. Nonetheless, compared anatomy and phisiology can provide good clues of how digestive tracts are shaped for more or less caloric food, for more or less fiber, for abundance and for scarcity. Objective: To review data from Compared Anatomy and Physiology, and in the Evolutionary Sciences that could help in the better comprehension of the metabolic surgery. Method: A focused review of the literature selecting information from these three fields of knowledge in databases: Cochrane Library, Medline and SciELO, articles and book chapters in English and Portuguese, between 1955 and 2019, using the headings "GIP, GLP-1, PYY, type 2 diabetes, vertebrates digestive system, hominid evolution, obesity, bariatric surgery ". Results: The digestive tract of superior animals shows highly specialized organs to digest and absorb specific diets. In spite of the wide variations of digestive systems, some general rules are observed. The proximal part of the digestive tract, facing the scarcity of sugars, is basically dedicated to generate sugar from different substrates (gluconeogenesis). Basic proximal gut tasks are to proportionally input free sugars, insulin, other fuels and to generate anabolic elements to the blood, some of them obesogenic. To limit the ingestion by satiety, by gastric emptying diminution and to limit the excessive elevation of major fuels (sugar and fat) in the blood are mostly the metabolict asks of the distal gut. A rapid and profound change in human diet composition added large amounts of high glycemic index foods. They seem to have caused an enhancement in the endocrine and metabolic activities of the proximal gut and a reduction in these activities of the distal gut. The most efficient models of metabolic surgery indeed make adjustments in this proximal/distal balance in the gut metabolic activities. Conclusion: Metabolic surgery works basically by making adjustments to the proximal and distal gut metabolic activities that resemble the action of natural selection in the development the digestive systems of superior animals.


RESUMO Introdução: A rede de questões fisiológicas envolvidas na cirurgia metabólica é muito complexa. No entanto, a anatomia e fisiologia comparadas podem fornecer boas pistas sobre como o trato digestivo é moldado para alimentos mais ou menos calóricos, para mais ou menos fibras, para abundância e escassez. Objetivo: Selecionar e analisar dados de Ciências Evolucionárias e Anatomia e Fisiologia Comparadas que ajudam na compreensão da cirurgia metabólica. Método: Revisão focada da literatura, selecionando informações desses três campos de conhecimento em bancos de dados da Cochrane Library, Medline e SciELO, artigos e capítulos de livros em inglês e português, entre 1950 e 2019, usando como descritores "GIP, GLP-1, PYY, type 2 diabetes, vertebrates digestive system, hominid evolution, obesity, bariatric surgery". Resultado: O trato digestivo de animais superiores mostra órgãos altamente especializados para digerir e absorver dietas específicas..A parte proximal, diante da escassez de açúcares, é basicamente dedicada à geração de açúcar a partir de diferentes substratos (gliconeogênese). As tarefas básicas do intestino proximal consistem em fornecer proporcionalmente açúcares livres, insulina e outros combustíveis e gerar elementos anabólicos no sangue, alguns deles obesogênicos. Limitar a ingestão pela saciedade, por diminuir o esvaziamento gástrico e limitar a elevação excessiva dos principais combustíveis (açúcar e gordura) no sangue são principalmente as tarefas metabólicas do intestino distal. Mudança rápida e profunda na composição da dieta humana causa elevação nas atividades endócrinas e metabólicas do intestino proximal e redução no intestino distal. Os modelos mais eficientes de cirurgia metabólica fazem ajustes nesse equilíbrio proximal-distal das atividades metabólicas intestinais. Conclusão: A cirurgia metabólica funciona basicamente fazendo ajustes nas atividades metabólicas do intestino proximal e distal que se assemelham à ação da seleção natural no desenvolvimento dos sistemas digestivos de animais superiores.

ABSTRACT

Background: Chinese hamster ovary (CHO) cells are the most dependable mammalian cells for the production of recombinant proteins. Replication-incompetent retroviral vector (retrovector) is an efficient tool to generate stable cell lines. Multiple copies of integrated genes by retrovector transduction results in improved recombinant protein yield. HEK-293 and their genetic derivatives are principal cells for retrovector production. Retrovectors packaged in HEK-293 cells pose a risk of infectious agent transmission, such as viruses and mycoplasmas, from serum and packaging cells. Results: In this report, retrovectors were packaged in CHO cells cultured in chemically defined (CD) media. The retrovectors were then used to transduce CHO cells. This method can block potential transmission of infectious agents from serum and packaging cells. With this method, we generated glucagon-like protein-1 Fc fusion protein (GLP-1-Fc) stable expression CHO cell lines. Productivity of GLP-1-Fc can reach 3.15 g/L. The GLP-1-Fc protein produced by this method has comparable bioactivity to that of dulaglutide (Trulicity). These stable cell lines retain 95­100% of productivity after 40 days of continuous culture (~48­56 generations). Conclusions: Suspension CHO cells are clean, safe, and reliable cells for retrovector packaging. Retrovectors packaged from this system could be used to generate CHO stable cell lines for recombinant protein expression.

ABSTRACT

La diabetes mellitus tipo 1 (DM1), es una enfermedad crónica caracterizada por la deficiencia de insulina debido a la pérdida de células ß pancreáticas, las alteraciones hormonales en la DM 1 no se limitan a la deficiencia de insulina; existiendo también secreción inadecuadada de glucagón en el período postprandial. Aunque el control glucémico con terapias intensivas con insulina ha reducido la incidencia de complicaciones microvascular y macrovasculares. La mayoría de las personas con DM1 tienen un control glucémico subóptimo; Por lo tanto, el uso de farmacoterapia adyuvante para mejorar el control ha sido de interés clínico. El uso de estos nuevos medicamentos brindaría la oportunidad de imitar más de cerca la fisiología pancreática normal, y contrarrestar otros mecanismos fisiopatológicos diferentes a Insulinopenia; contribuyendo a lograr un mejor control metabólico y expectativa de vida.


Type 1 diabetes mellitus (T1DM), is a chronic disease characterized by insulin deficiency due to the loss of pancreatic ß cells, the hormonal alterations in T1DM are not limited to insulin deficiency; there is also a deregulated glucagon secretion in the postprandial period. Although glycemic control with intensive therapies with insulin has reduced the incidence of microvascular and macrovascular complications, most people with T1DM1 glycemic control; therefore, the use of adjuvant pharmacotherapy to improve control has been of clinical interest. The use of these new drugs would offer the opportunity to imitate more closely the normal pancreatic physiology, and to counteract other physiopathological mechanisms different from insulinopenia; contributing to achieve better metabolic control and life expectancy.

ABSTRACT

BACKGROUND: A premeal load of protein can increase satiety and reduce energy intake. Dietary fiber also conveys metabolic benefits by modulating energy intake. We made a protein-enriched, dietary fiber-fortified bar (PFB) and aimed to investigate its effects on food intake and gut hormone secretion in healthy individuals.METHODS: Twenty subjects with normal glucose tolerance were enrolled. On three separate visits, the subjects received, in a randomized order, one of the following: a PFB containing 73 kcal with 10.7 g of protein and 12.7 g of dietary fiber; a usual bar (UB) containing the same calories as the PFB but only 0.9 g of protein and no dietary fiber; or water (control). After 15 minutes, the subjects had ad libitum intake of a test meal. Food consumption, appetite, and plasma gut hormone levels were measured.RESULTS: Total energy intake, including the bar and the test meal, was significantly reduced with the PFB preload compared to the water (904.4±534.9 kcal vs. 1,075.0±508.0 kcal, P=0.016). With the UB preload, only the intake of the test meal was reduced (P=0.044) but not the total energy intake (P=0.471) than the water. Fullness was also significantly increased after the PFB. In addition, postprandial glucose levels decreased and glucagon-like peptide-1 levels increased with the PFB compared with both the UB and water.CONCLUSION: In healthy individuals, a premeal supplementation of PFB reduced total energy intake and decreased postprandial glucose excursion.

ABSTRACT

BACKGROUND: We performed this study to identify factors related to intact incretin levels in patients with type 2 diabetes mellitus (T2DM). METHODS: We cross-sectionally analyzed 336 patients with T2DM. Intact glucagon-like peptide 1 (iGLP-1) and intact glucose-dependent insulinotropic polypeptide (iGIP) levels were measured in a fasted state and 30 minutes after ingestion of a standard mixed meal. The differences between 30 and 0 minute iGLP-1 and iGIP levels were indicated as ΔiGLP-1 and ΔiGIP. RESULTS: In simple correlation analyses, fasting iGLP-1 was positively correlated with glucose, C-peptide, creatinine, and triglyceride levels, and negatively correlated with estimated glomerular filtration rate. ΔiGLP-1 was positively correlated only with ΔC-peptide levels. Fasting iGIP showed positive correlations with glycosylated hemoglobin (HbA1c) and fasting glucose levels, and negative correlations with ΔC-peptide levels. ΔiGIP was negatively correlated with diabetes duration and HbA1c levels, and positively correlated with Δglucose and ΔC-peptide levels. In multivariate analyses adjusting for age, sex, and covariates, fasting iGLP-1 levels were significantly related to fasting glucose levels, ΔiGLP-1 levels were positively related to ΔC-peptide levels, fasting iGIP levels were related to fasting C-peptide levels, and ΔiGIP levels were positively related to ΔC-peptide and Δglucose levels. CONCLUSION: Taken together, intact incretin levels are primarily related to C-peptide and glucose levels. This result suggests that glycemia and insulin secretion are the main factors associated with intact incretin levels in T2DM patients.

ABSTRACT

BACKGROUND: Based on reported results of three large cardiovascular outcome trials (CVOTs) of glucagon-like peptide 1 receptor agonists (GLP-1 RAs), we aimed to investigate the overall effect of GLP-1 RAs on major adverse cardiovascular events (MACEs) and to identify subpopulations exhibiting the greatest cardiovascular (CV) benefit. METHODS: Three CVOTs reporting effects of long-acting GLP-1 RAs were included: LEADER (liraglutide), SUSTAIN-6 (semaglutide), and EXSCEL (exenatide once weekly). In all studies, the primary endpoint was three-point MACE, comprising CV death, non-fatal myocardial infarction, and non-fatal stroke. Overall effect estimates were calculated as hazard ratios and 95% confidence intervals (CIs) using the random-effects model; subgroup analyses reported in the original studies were similarly analyzed. RESULTS: Overall, statistically significant risk reductions in MACE and CV death were observed. Subgroup analysis indicated a significant racial difference with respect to CV benefit (P for interaction <0.001), and more substantial risk reductions were observed in subjects of African origin (relative risk [RR], 0.78; 95% CI, 0.60 to 0.99) and in Asians (RR, 0.35; 95% CI, 0.09 to 1.32). However, post hoc analysis (Bonferroni method) revealed that only Asians exhibited a significantly greater CV benefit from treatment, compared with white subjects (P<0.0001). CONCLUSION: Long-acting GLP-1 RAs reduced risks of MACE and CV deaths in high-risk patients with type 2 diabetes mellitus. Our findings of a particularly effective reduction in CV events with GLP-1 RA in Asian populations merits further exploration and dedicated trials in specific populations.

ABSTRACT

The Committee of Clinical Practice Guidelines of the Korean Diabetes Association revised and updated the 6th Clinical Practice Guidelines in 2019. Targets of glycemic, blood pressure, and lipid control in type 2 diabetes mellitus (T2DM) were updated. The obese and overweight population is increasing steadily in Korea, and half of the Koreans with diabetes are obese. Evidence-based recommendations for weight-loss therapy for obesity management as treatment for hyperglycemia in T2DM were provided. In addition, evidence from large clinical studies assessing cardiovascular outcomes following the use of sodium-glucose cotransporter-2 inhibitors and glucagon-like peptide 1 receptor agonists in patients with T2DM were incorporated into the recommendations.

ABSTRACT

The prevalence of type 2 diabetes mellitus (T2DM), which is associated with cardiovascular morbidity and mortality, is increasing worldwide. Although there have been advances in diabetes treatments that reduce microvascular complications (nephropathy, neuropathy, retinopathy), many clinical studies have found that conventional oral hypoglycemic agents and glucose control alone failed to reduce cardiovascular disease. Thus, incretin-based therapies including glucagon-like peptide 1 (GLP-1) receptor agonists (RAs) and sodium-glucose cotransporter 2 inhibitors (SGLT-2Is) represent a new area of research, and may serve as novel therapeutics for treating hyperglycemia and modifying other cardiovascular risk factors. Recently, it has been confirmed that several drugs in these classes, including canagliflozin, empagliflozin, semaglutide, and liraglutide, are safe and possess cardioprotective effects. We review the most recent cardiovascular outcome trials on GLP-1RAs and SGLT-2Is, and discuss their implications for treating patients with T2DM in terms of protective effects against cardiovascular disease.

ABSTRACT

Weight loss is an important goal in the management of several chronic conditions, including type 2 diabetes mellitus, and pharmacological therapies that aid weight loss are appealing. Glucagon-like peptide-1 receptor agonists (GLP-1RAs) and sodium-glucose cotransporter 2 inhibitors (SGLT2is) are novel glucose-lowering therapies that have been shown to induce clinically significant reductions in body weight. However, this weight loss may not be attributed solely to fat mass (FM). Given the importance of skeletal muscle and lean body mass (LBM) on cardio-metabolic health and physical function, we reviewed the available literature reporting the effects of GLP-1RAs and SGLT2is on body composition. Results demonstrate that, in most circumstances, the weight loss associated with both therapies predominantly comprises a reduction in FM, although significant heterogeneity exists between studies. In over half of the studies identified, the proportion of LBM reduction ranged between 20% and 50% of total weight lost, which is consistent with diet-induced weight loss and bariatric surgery. No clear differences existed between GLP-1RAs and SGLT2is. Consequently, the loss of LBM and skeletal muscle associated with weight loss induced by GLP-1RAs and SGLT2is warrants attention. Strategies to preserve skeletal muscle and improve physical function, for example through structured exercise, are of great importance.

ABSTRACT

IL-18 is a crucial pro-inflammatory cytokine that mediates chronic intestinal inflammation. Metformin, an anti-diabetic drug, was reported to have ameliorative effects on inflammatory bowel disease. Recently, the mechanism of action of metformin was explained as a modulation of gut microbiota. In this study, fecal microbiota transplantation (FMT) using fecal material from metformin-treated mice was found to upregulate the expression of GLP-1 and pattern-recognition receptors TLR1 and TLR4 for the improvement in hyperglycemia caused by a high-fat diet. Further, FMT downregulated the expression of the inflammatory cytokine IL-18. Within the genera Akkermansia, Bacteroides, and Butyricimonas, which were promoted by metformin therapy, Butyricimonas was found to be consistently abundant following FMT. Our findings suggest that modulation of gut microbiota is a key factor for the anti-inflammatory effects of metformin which is used for the treatment of hyperglycemia.

ABSTRACT

Patients with hyperglycemia are at a high risk of cardio- and cerebrovascular diseases. Diabetes patients also have poor outcomes after cerebrovascular disease development. Several classes of drugs are used for diabetes management in clinical practice. Thiazolidinedione (TZD) was introduced in the late 1990s, and new antidiabetic agents have been introduced since 2000. After issues with rosiglitazone in 2007, the U.S. Food and Drug Administration strongly recommended that trials investigating cardiovascular risk associated with new antidiabetic medications should be conducted before drug approval in the United States, to prove the safety of these new drugs and to determine their superiority to previous medications. Currently, results are available from two studies with TZD focusing on cardiovascular diseases, including stroke, and from 12 cardiovascular outcome trials focusing on major adverse cardiovascular events associated with new antidiabetic agents (four with dipeptidyl peptidase-4 inhibitors, three with sodium-glucose cotransporter-2 inhibitors, and five with glucagon-like peptide-1 analogues). These studies showed different results for primary cardiovascular outcomes and stroke prevention. It is important to determine whether prescription of TZD or new antidiabetic medications compared to conventional treatment, such as sulfonylurea or insulin, is better for stroke management. Furthermore, it is unclear whether drugs in the same class show greater safety and efficacy than other drugs for stroke management.

ABSTRACT

In 2018, the American Diabetes Association (ADA) and the European Association for the Study of Diabetes (EASD) published a consensus recommendation on management of hyperglycemia. This consensus report emphasized the need for patient-centered management considering multimorbidity and individual patient preferences and barriers. Patients with type 2 diabetes with established atherosclerotic cardiovascular disease who fail to control blood glucose with the initial glucose-lowering medication are recommended a sodium-glucose cotransporter 2 (SGLT2) inhibitor or a glucagon-like peptide 1 (GLP-1) receptor agonist. For patients with chronic kidney disease and heart failure, SGLT2 inhibitors are recommended. In patients who need an injectable medication, GLP-1 receptor agonists are the preferred choice over insulin. In this section, we summarize “Management of Hyperglycemia in Type 2 Diabetes, 2018. A Consensus Report by the American Diabetes Association (ADA) and the European Association for the Study of Diabetes (EASD).”

ABSTRACT

Globally, the problem of obesity is increasing, and the prevalence of obesity in Korea is also rising rapidly. Obesity is a risk factor for cardiometabolic diseases including type 2 diabetes mellitus, hypertension, cardiovascular disease, and some types of cancer. Therefore, prevention of various metabolic diseases or symptom relief through effective treatment of obesity is a very important problem. According to the obesity guidelines of the Obesity Society of Korea in 2018, obesity medication is recommended for patients with a body mass index (BMI) of 30 kg/m² or more or a BMI of 27 kg/m² or more, and one or more obesity accompanying diseases (type 2 diabetes, hypertension, dyslipidemia). In this case, it is recommended that the basic treatment for obesity (diet, exercise, and behavior therapy) should be performed in parallel with Saxenda® treatment. The glucagon-like peptide 1 analogue, Saxenda®, has been validated as a long-term effective and safe treatment for obesity, and is expected to be a promising drug for the treatment of obesity and the prevention of pre-diabetes in the future. However, in Korea, where non-standard obesity treatments are widely practiced, it is necessary to improve the health of obese patients by being treated with Saxenda® along with diet, exercise and behavior therapy.

ABSTRACT

According to the American Diabetes Association (ADA) and the European Association for the Study of Diabetes guideline for treatment of diabetes, glucagon-like peptide-1 receptor agonist (GLP-1 RA) is recommended in diabetic patients with established atherosclerotic cardiovascular disease. This recommendation is based on the results of recent cardiovascular outcome trials of this kind of medications. GLP-1 RAs have a glucose lowering effect with weight loss and a lower incidence of hypoglycemia, and can improve cardiovascular outcomes such as three-point major cardiovascular events composed of death from cardiovascular causes, non-fatal myocardial infarction, and non-fatal stroke. Also, several GLP-1 RAs have beneficial effects on renal outcomes, mainly due to improvement in macroalbuminuria. In addition, high-dose liraglutide (3 mg/day subcutaneous injection) showed efficacy for reducing body weight. Therefore GLP-1 RA may be effective in patients with established cardiovascular disease, chronic kidney disease, and/or metabolic syndrome.
