RESUMO

INTRODUCTION: The efficacy of liraglutide for treating type 2 diabetes mellitus and obesity is well established, but their role in the treatment of weight regain after bariatric surgery remains unclear. METHODS: We searched PubMed, Embase, and Cochrane Library databases in January 2024. A random-effects model was employed to compute mean differences (MD) and events per 100 observations with 95% confidence intervals (CI) for continuous and binary endpoints. Statistical analysis was performed using R software. RESULTS: A total of 16 studies were included and 881 individuals. Patients were mostly female (50%), aged 36 to 55 years, with a mean body mass index (BMI) of 39.4 kg/m2, and had BS surgery 5 years prior. Over a mean follow-up time ranging from 3 months to 4 years, it was observed a statistically significant reduction in BMI (MD - 8.56 kg/m2; 95% CI 3.34 to 13.79; p < 0.01) and a mean reduction in total weight (MD - 16.03 kg; 95% CI 0.03 to 32.02; p = 0.05) after liraglutide use. Additionally, 65% of patients undertaking liraglutide showed total body weight loss (BWL) above 5% (65.8 events per 100 observations; 95% CI 54.96 to 75.20; p < 0.01), while 26% lost more than 10% of total BWL (26.77 events per 100 observations; 95% CI 19.17 to 36.02; p < 0.01). A limitation is a variability between the studies. CONCLUSIONS: Our findings support the use of liraglutide for weight management in patients who experience weight regain after BS. Liraglutide is well tolerated and promotes significant weight loss, providing clinicians with a therapeutic option for this clinical challenge.

RESUMO

INTRODUCTION: Leukocytoclastic vasculitis (LCV) is a small vessel vasculitis involving arterioles, capillaries and postcapillary venules. LCV is generally confined to the skin, with extracutaneous manifestations occurring less frequently. LCV has multiple potential etiologies. Indeed, histological LCV can be found in anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis, immune complex vasculitis, vasculitis associated with systemic diseases (i.e. sarcoidosis, Sjögren's syndrome, rheumatoid arthritis, and systemic lupus erythematosus), or in vasculitis associated with cancer, infections, sepsis and use of certain medications. LCV can also be idiopathic in up to 50% of cases. CASE REPORT: Semaglutide is a glucagon-like peptide 1 (GLP-1) receptor agonist used for management of type 2 diabetes mellitus (T2DM), obesity and overweight associated with one or more weight-related comorbidities. A case of drug-induced LCV has already been described with the use of once-daily oral semaglutide. Herein, we describe the first case of skin-limited LCV induced by once-weekly subcutaneous semaglutide in a 73-year-old man with T2DM, who experienced the complete resolution of the skin lesions shortly after the discontinuation of semaglutide therapy. CONCLUSION: Future prospective studies, adverse event reporting and post-marketing surveillance will certainly contribute to establishing if LCV represents a less rare than expected side effect of both oral and subcutaneous semaglutide formulations.

RESUMO

Chronic kidney disease (CKD) is a growing global public health challenge worldwide. In Mexico, CKD prevalence is alarmingly high and remains a leading cause of morbidity and mortality. Diabetic kidney disease (DKD), a severe complication of diabetes, is a leading determinant of CKD. The escalating diabetes prevalence and the complex regional landscape in Mexico underscore the pressing need for tailored strategies to reduce the burden of CKD. This narrative review, endorsed by the Mexican College of Nephrologists, aims to provide a brief overview and specific strategies for healthcare providers regarding preventing, screening, and treating CKD in patients living with diabetes in all care settings. The key topics covered in this review include the main cardiometabolic contributors of DKD (overweight/obesity, hyperglycemia, arterial hypertension, and dyslipidemia), the identification of kidney-related damage markers, and the benefit of novel pharmacological approaches based on Sodium-Glucose Co-Transporter-2 Inhibitors (SGLT2i) and Glucagon-Like Peptide-1 Receptor Agonists (GLP-1 RA). We also address the potential use of novel therapies based on Mineralocorticoid Receptor Antagonists (MRAs) and their future implications. Emphasizing the importance of multidisciplinary treatment, this narrative review aims to promote strategies that may be useful to alleviate the burden of DKD and its associated complications. It underscores the critical role of healthcare providers and advocates for collaborative efforts to enhance the quality of life for millions of patients affected by DKD.

RESUMO

This review examines the impact of obesity on the pathophysiology of heart failure with preserved ejection fraction (HFpEF) and focuses on novel mechanisms for HFpEF prevention using a glucagon-like peptide-1 receptor agonism (GLP-1 RA). Obesity can lead to HFpEF through various mechanisms, including low-grade systemic inflammation, adipocyte dysfunction, accumulation of visceral adipose tissue, and increased pericardial/epicardial adipose tissue (contributing to an increase in myocardial fat content and interstitial fibrosis). Glucagon-like peptide 1 (GLP-1) is an incretin hormone that is released from the enteroendocrine L-cells in the gut. GLP-1 reduces blood glucose levels by stimulating insulin synthesis, suppressing islet α-cell function, and promoting the proliferation and differentiation of ß-cells. GLP-1 regulates gastric emptying and appetite, and GLP-1 RA is currently indicated for treating type 2 diabetes (T2D), obesity, and metabolic syndrome (MS). Recent evidence indicates that GLP-1 RA may play a significant role in preventing HFpEF in patients with obesity, MS, or obese T2D. This effect may be due to activating cardioprotective mechanisms (the endogenous counter-regulatory renin angiotensin system and the AMPK/mTOR pathway) and by inhibiting deleterious remodeling mechanisms (the PKA/RhoA/ROCK pathway, aldosterone levels, and microinflammation). However, there is still a need for further research to validate the impact of these mechanisms on humans.

RESUMO

OBJECTIVE: Glucagon-like peptide-1 receptor belongs to the B family of G protein-coupled receptors, serving as a binding protein in membranes and is widely expressed in human tissues. Upon stimulation by its agonist, the glucagon-like peptide-1, the receptor plays a role in glucose metabolism, enhancing insulin secretion, and regulating appetite in the hypothalamus. Mutations in the glucagon-like peptide-1 receptor gene can lead to physiological changes that may explain phenotypic variations in individuals with obesity and diabetes. Therefore, this study aimed to evaluate missense variants of the glucagon-like peptide-1 receptor gene. METHODS: Data mining was performed on the single nucleotide polymorphism database, retrieving a total of 16,399 variants. Among them, 356 were missense. These 356 variants were analyzed using the PolyPhen-2 and filtered based on allele frequency, resulting in 6 pathogenic variants. RESULTS: D344E, A239T, R310Q, R227H, R421P, and R176G were analyzed using four different prediction tools. The D344E and A239T resulted in larger amino acid residues compared to their wild-type counterparts. The D344E showed a slightly destabilized structure, while A239T affected the transmembrane helices. Conversely, the R310Q, R227H, R421P, and R176G resulted in smaller amino acid residues than the wild-type, leading to a loss of positive charge and increased hydrophobicity. Particularly, the R421P, due to the presence of proline, significantly destabilized the α-helix structure and caused severe damage to the receptor. CONCLUSION: Elucidating the glucagon-like peptide-1 receptor variants and their potentially detrimental effects on receptor functionality can contribute to an understanding of metabolic diseases and the response to available pharmacological treatments.

RESUMO

Obesity is a chronic, recurring, progressive disease and a major public health problem associated with several other diseases that lead to disability, morbidity, and mortality. The prevalence of obesity has increased at pandemic levels, along with increasing weight-related comorbidities and deaths worldwide. Lifestyle interventions alone provide clinically significant long-term weight loss in only a small proportion of individuals, and bariatric surgery is not suitable or desirable for all patients. Historically, anti-obesity medications achieved a mean efficacy with weight loss between 5 and 10%, which significantly impacted several comorbidities and risk factors, but the average efficacy of these medications remained lower than that expected by both patients and health care professionals and eventually curbed long-term use. Moreover, there is no direct evidence on the impact of anti-obesity medications on cardiovascular outcomes. Semaglutide is a newer anti-obesity medication that changes the overall landscape, as phase 3 studies show a mean weight loss near the 15% threshold and significant proportions of patients with a weight loss of greater than 20%. In this review, we focus on the currently available anti-obesity medications, discuss the results of semaglutide, and present perspectives on the future of obesity treatment after semaglutide.

RESUMO

RESUMEN Inicialmente desarrollados como medicamentos para la diabetes mellitus, los agonistas GLP-1 han ganado mucha popularidad en el tratamiento de la obesidad y la pérdida de peso. El presente caso describe a una mujer de 69 años con antecedente de úlcera péptica y consumo de AINES, quien cursó con dolor abdominal e intolerancia oral refractaria al manejo convencional, por lo que se realizó una endoscopía digestiva alta, diagnosticándose gastroparesia severa. Al ampliar la anamnesis, se reveló el uso subrepticio de semaglutida. Se continuó con terapia de soporte y los síntomas remitieron espontáneamente. El presente reporte de caso tiene como objetivo advertir los riesgos potenciales del uso de análogos de GLP-1 en el contexto de una endoscopía con sedación.


ABSTRACT Initially developed as medications for diabetes mellitus, GLP-1 agonists have gained much popularity in the treatment of obesity and weight loss. The present case describes a 69-yearold woman with a history of peptic ulcer and use of NSAIDs, who presented with abdominal pain and oral intolerance refractory to conventional management, for which an upper digestive endoscopy was performed, diagnosing severe gastroparesis. Asking more about the story, revealed surreptitious use of semaglutide. She continued with supportive therapy and the symptoms resolved spontaneously. The present case report aims to warn of the potential risks of the use of GLP-1 analogues in the context of endoscopy with sedation.

RESUMO

Nausea is an uncomfortable sensation that accompanies many therapeutics, especially diabetes treatments involving glucagon-like peptide-1 receptor (GLP1R) agonists. Recent studies in mice have revealed that GLP1R-expressing neurons in the area postrema play critical roles in nausea. Here, we characterized a ligand-conjugated saporin that can efficiently ablate GLP1R+ cells from humans, mice, and the Suncus murinus, a small animal model capable of emesis. This new tool provides a strategy to manipulate specific neural pathways in the area postrema in the Suncus murinus and may help elucidate roles of area postrema GLP1R+ neurons in emesis during therapeutics involving GLP1R agonists.

RESUMO

BACKGROUND: Metabolic dysfunction-associated steatotic liver disease (MASLD) is the most common liver disease affecting 30% of the world's population and is often associated with metabolic disorders such as metabolic syndrome, type 2 diabetes (T2D), and cardiovascular disease. This review is an update of the Brazilian Diabetes Society (Sociedade Brasileira de Diabetes [SBD]) evidence-based guideline for the management of MASLD in clinical practice. METHODS: The methodology was published previously and was defined by the internal institutional steering committee. The SBD Metabolic Syndrome and Prediabetes Department drafted the manuscript, selecting key clinical questions for a narrative review using MEDLINE via PubMed with the MeSH terms [diabetes] and [fatty liver]. The best available evidence was reviewed, including randomized clinical trials (RCTs), meta-analyses, and high-quality observational studies related to MASLD. RESULTS AND CONCLUSIONS: The SBD Metabolic Syndrome and Prediabetes Department formulated 9 recommendations for the management of MASLD in people with prediabetes or T2D. Screening for the risk of advanced fibrosis associated with MASLD is recommended in all adults with prediabetes or T2D. Lifestyle modification (LSM) focusing on a reduction in body weight of at least 5% is recommended as the first choice for these patients. In situations where LSMs are insufficient to achieve weight loss, the use of anti-obesity medications is recommended for those with a body mass index (BMI) ≥ 27 kg/m2. Pioglitazone and glucagon-like peptide-1 receptor agonists (GLP-1RA) monotherapy are the first-line pharmacological treatments for steatohepatitis in people with T2D, and sodium-glucose cotransporter-2 (SGLT2) inhibitors may be considered in this context. The combination of these agents may be considered in the treatment of steatohepatitis and/or fibrosis, and bariatric surgery should be considered in patients with a BMI ≥ 35 kg/m2, in which the combination of LSM and pharmacotherapy has not been shown to be effective in improving MASLD.

RESUMO

Thyroid cancer has shown a parallel increase with diabetes in the last few years. This narrative review aims to explain the association between these two entities, focusing on insulin resistance as the mediator and exploring the effects of antidiabetic agents on thyroid cancer incidence and progression.We searched Pubmed for English-written articles on insulin resistance, diabetes, antidiabetic treatments, and thyroid cancer reported from January 2019 to April 2023. Exclusion criteria were preclinical and clinical studies involving a population with thyroid dysfunction, benign nodular goiter, or those that only analyzed thyroid cancer's association with obesity.The results of the narrative literature review revealed 96 articles. Additionally, four studies from a manual search were retrieved. After the exclusion criteria were applied, we included 20 studies. Out of 8 studies on insulin-resistant or Metabolic Syndrome patients, all suggest a positive association with thyroid cancer. At the same time, for diabetes, four out of five publications support a link with thyroid cancer. The seven remaining studies on antidiabetics suggest that metformin might benefit thyroid cancer. In contrast, the evidence for an association between Glucagon-like peptide-1 receptor agonists (GLP-1 RA) and increased thyroid cancer findings is limited.In conclusion, the association between thyroid cancer and diabetes may be explained by insulin resistance, as shown in observational studies. However, the causal role is yet to be defined. Although the wide use of different antidiabetic agents has been related to thyroid cancer prevalence and progression, future research with drugs such as metformin or GLP-1 RA is still needed.

RESUMO

BACKGROUND: The escalating prevalence of type 2 diabetes (T2DM) poses an unparalleled economic catastrophe to developing countries. Cardiovascular diseases remain the primary source of costs among individuals with T2DM, incurring expenses for medications, hospitalizations, and surgical interventions. Compelling evidence suggests that the risk of cardiovascular outcomes can be reduced by three classes of glucose-lowering therapies (GLT), including SGLT2i, GLP-1A, and pioglitazone. However, an evidence-based and cost-effective protocol is still unavailable for many countries. The objective of the current study is to compare the effectiveness and cost-effectiveness of GLT in individuals with T2DM in Brazil. METHODS: We employed Bayesian Networks to calculate the incremental cost-effectiveness ratios (ICER), expressed in international dollars (Int$) per disease-adjusted life years [DALYs] averted. To determine the effectiveness of GLT, we conducted a systematic review with network meta-analysis (NMA) to provide insights for our model. Additionally, we obtained cardiovascular outcome incidence data from two real-world cohorts comprising 851 and 1337 patients in primary and secondary prevention, respectively. Our cost analysis took into account the perspective of the Brazilian public health system, and all values were converted to Int$. RESULTS: In the NMA, SGLT2i [HR: 0.81 (95% CI 0.69-0.96)], GLP-1A [HR: 0.79 (95% CI 0.67-0.94)], and pioglitazone [HR: 0.73 (95% CI 0.59-0.91)] demonstrated reduced relative risks of non-fatal cardiovascular events. In the context of primary prevention, pioglitazone yielded 0.2339 DALYs averted, with an ICER of Int$7,082 (95% CI 4,521-10,770) per DALY averted when compared to standard care. SGLT2i and GLP-1A also increased effectiveness, resulting in 0.261 and 0.259 DALYs averted, respectively, but with higher ICERs of Int$12,061 (95% CI: 7,227-18,121) and Int$29,119 (95% CI: 23,811-35,367) per DALY averted. In the secondary prevention scenario, all three classes of treatments were deemed cost-effective at a maximum willingness-to-pay threshold of Int$26,700. Notably, pioglitazone consistently exhibited the highest probability of being cost-effective in both scenarios. CONCLUSIONS: In Brazil, pioglitazone presented a higher probability of being cost-effective both in primary and secondary prevention, followed by SGLT2i and GLP-1A. Our findings support the use of cost-effectiveness models to build optimized and hierarchical therapeutic strategy in the management of T2DM. TRIAL REGISTRATION: CRD42020194415.

RESUMO

INTRODUCTION: This study developed a simple algorithm based on clinical results described in medical literature and which allows one to simplify complex insulin regimes with IdegLira to avoid adverse events related to the complexity of some insulin treatments. METHODS: We conducted a systematic review of the literature that allowed us to identify studies that evaluated the clinical result of simplifying complex insulin regimes. The authors reviewed the common factors these simpler regimes had, including the type of patients who used them. RESULTS: We found nine clinical studies published between 2017 and 2022, eight performed in Europe and one in Latin America. The monitoring time of the studies ranged between 3 and 18 months. The size of the study populations was between 61 and 611 patients (the latter was in five countries). In all studies, HbA1c decreased by 0.6-1.7% and the weight decreased by 0.1-3.11 kg. CONCLUSIONS: On the basis of the findings of these studies, we made some recommendations for clinical practice to simplify treatment. The results of these studies support an algorithm that simplifies the treatment of complex insulin regimens.

RESUMO

Obesity is a prevalent chronic disorder and a well-known risk factor for cardiovascular disease. However, the evidence of treating obesity for primary prevention of major cardiovascular events is still scarce and controversial. In this review, we provided a comprehensive description of the current evidence in treating obesity regarding cardiovascular protection. Bariatric surgery appears to be the most robust method to reduce events in people without established cardiovascular disease. High compliance to lifestyle interventions can further reduce cardiovascular risk. Concerning pharmacological therapies, a post hoc analysis from SUSTAIN-6 and a meta-analysis from STEP trials suggest that semaglutide, a GLP-1 receptor agonist, could reduce cardiovascular events in people without established cardiovascular disease. The first study addressed specifically a high-risk population with diabetes and, the second, low- or intermediary-risk individuals without diabetes. Tirzepatide, a novel dual GIP/GLP-1 agonist, although not yet tested in specific cardiovascular outcomes trials, could be an alternative since it induces loss in weight similar to the achieved by bariatric surgery. Therefore, extrapolated data in distinct baseline cardiovascular risk populations suggest that these two drugs could be used in primary prevention with the aim of preventing cardiovascular events, but the grade of this evidence is still low. Specifically designed studies are needed to address this specific topic.

RESUMO

BACKGROUND: The management of antidiabetic therapy in people with type 2 diabetes (T2D) has evolved beyond glycemic control. In this context, Brazil and Portugal defined a joint panel of four leading diabetes societies to update the guideline published in 2020. METHODS: The panelists searched MEDLINE (via PubMed) for the best evidence from clinical studies on treating T2D and its cardiorenal complications. The panel searched for evidence on antidiabetic therapy in people with T2D without cardiorenal disease and in patients with T2D and atherosclerotic cardiovascular disease (ASCVD), heart failure (HF), or diabetic kidney disease (DKD). The degree of recommendation and the level of evidence were determined using predefined criteria. RESULTS AND CONCLUSIONS: All people with T2D need to have their cardiovascular (CV) risk status stratified and HbA1c, BMI, and eGFR assessed before defining therapy. An HbA1c target of less than 7% is adequate for most adults, and a more flexible target (up to 8%) should be considered in frail older people. Non-pharmacological approaches are recommended during all phases of treatment. In treatment naïve T2D individuals without cardiorenal complications, metformin is the agent of choice when HbA1c is 7.5% or below. When HbA1c is above 7.5% to 9%, starting with dual therapy is recommended, and triple therapy may be considered. When HbA1c is above 9%, starting with dual therapyt is recommended, and triple therapy should be considered. Antidiabetic drugs with proven CV benefit (AD1) are recommended to reduce CV events if the patient is at high or very high CV risk, and antidiabetic agents with proven efficacy in weight reduction should be considered when obesity is present. If HbA1c remains above target, intensification is recommended with triple, quadruple therapy, or even insulin-based therapy. In people with T2D and established ASCVD, AD1 agents (SGLT2 inhibitors or GLP-1 RA with proven CV benefit) are initially recommended to reduce CV outcomes, and metformin or a second AD1 may be necessary to improve glycemic control if HbA1c is above the target. In T2D with HF, SGLT2 inhibitors are recommended to reduce HF hospitalizations and mortality and to improve HbA1c. In patients with DKD, SGLT2 inhibitors in combination with metformin are recommended when eGFR is above 30 mL/min/1.73 m2. SGLT2 inhibitors can be continued until end-stage kidney disease.

RESUMO

Obesity and type 2 diabetes mellitus (T2DM) cause morphofunctional alterations in pancreatic islet alpha and beta cells. Therefore, we hypothesize that the new GLP-1/Glucagon receptor dual agonist cotadutide may benefit islet cell arrangement and function. Twelve-week-old C57BL/6 male mice were fed a control diet (C, 10 % kJ fat) or a high-fat diet (HF, 50 % kJ fat) for ten weeks. Then, the animals were divided into four groups for an additional 30 days and daily treated with subcutaneous cotadutide (30 nmol/kg) or vehicle: C, CC (control+cotadutide), HF, and HFC (high-fat+cotadutide). Cotadutide led to weight loss and reduced insulin resistance in the HFC group, increasing insulin receptor substrate 1 and solute carrier family 2 gene expressions in isolated islets. Also, cotadutide enhanced transcriptional factors related to islet cell transdifferentiation, decreasing aristaless-related homeobox and increasing the paired box 4 and 6, pancreatic and duodenal homeobox 1, v-maf musculoaponeurotic fibrosarcoma oncogene family protein A, neurogenin 3, and neurogenic differentiation 1. In addition, cotadutide improved the proliferating cell nuclear antigen, NK6 homeobox 1, B cell leukemia/lymphoma 2, but lessening caspase 3. Furthermore, cotadutide mitigated the endoplasmic reticulum (ER) stress-responsive genes, reducing transcription factor 4, DNA-damage-inducible transcript 3, and growth arrest and DNA-damage-inducible 45. In conclusion, our data demonstrated significant beneficial actions of cotadutide in DIO mice, such as weight loss, glycemic control, and insulin resistance improvement. In addition, cotadutide counteracted the pathological adaptive cellular arrangement of the pancreatic islet in obese mice, improving the markers of the transdifferentiating pathway, proliferation, apoptosis, and ER stress.

RESUMO

Introduction: The modern food environment facilitates excessive calorie intake, a major driver of obesity. Glucagon-like peptide 1 (GLP1) is a neuroendocrine peptide that has been the basis for developing new pharmacotherapies against obesity. The GLP1 receptor (GLP1R) is expressed in central and peripheral tissues, and activation of GLP1R reduces food intake, increases the expression of thermogenic proteins in brown adipose tissue (BAT), and enhances lipolysis in white adipose tissue (WAT). Obesity decreases the efficiency of GLP1R agonists in reducing food intake and body weight. Still, whether palatable food intake before or during the early development of obesity reduces the effects of GLP1R agonists on food intake and adipose tissue metabolism remains undetermined. Further, whether GLP1R expressed in WAT contributes to these effects is unclear. Methods: Food intake, expression of thermogenic BAT proteins, and WAT lipolysis were measured after central or peripheral administration of Exendin-4 (EX4), a GLP1R agonist, to mice under intermittent-short exposure to CAF diet (3 h/d for 8 days) or a longer-continuous exposure to CAF diet (24 h/d for 15 days). Ex-vivo lipolysis was measured after EX4 exposure to WAT samples from mice fed CAF or control diet for 12 weeks. . Results: During intermittent-short exposure to CAF diet (3 h/d for 8 days), third ventricle injection (ICV) and intra-peritoneal administration of EX4 reduced palatable food intake. Yet, during a longer-continuous exposure to CAF diet (24 h/d for 15 days), only ICV EX4 administration reduced food intake and body weight. However, this exposure to CAF diet blocked the increase in uncoupling protein 1 (UCP1) caused by ICV EX4 administration in mice fed control diet. Finally, GLP1R expression in WAT was minimal, and EX4 failed to increase lipolysis ex-vivo in WAT tissue samples from mice fed CAF or control diet for 12 weeks. . Discussion: Exposure to a CAF diet during the early stages of obesity reduces the effects of peripheral and central GLP1R agonists, and WAT does not express a functional GLP1 receptor. These data support that exposure to the obesogenic food environment, without the development or manifestation of obesity, can alter the response to GLP1R agonists. .

RESUMO

AIMS: This subanalysis of the SoliMix trial assessed the efficacy and safety of advancing basal insulin (BI) therapy with iGlarLixi versus BIAsp 30 in people with type 2 diabetes (T2D) living in Latin American (LATAM) countries, i.e. Argentina and Mexico (N = 160). MATERIALS AND METHODS: SoliMix (EudraCT: 2017-003370-13) was a 26-week, open-label, multicentre study, where adults with T2D suboptimally controlled with BI plus one or two oral glucose-lowering drugs and glycated haemoglobin (HbA1c) ≥7.5% to ≤10% were randomized to once-daily iGlarLixi or twice-daily BIAsp 30. Primary efficacy endpoints were non-inferiority in HbA1c reduction (margin 0.3%) or superiority in body weight change for iGlarLixi versus BIAsp 30. RESULTS: Both primary efficacy endpoints were met in the LATAM region. After 26 weeks, HbA1c was reduced by 1.8% with iGlarLixi and 1.4% with BIAsp 30, meeting non-inferiority [least squares mean difference -0.47% (95% confidence interval: -0.82, -0.11); p < .001]. iGlarLixi was superior to BIAsp 30 for body weight change [least squares mean difference -1.27% (95% confidence interval: -2.41, -0.14); p = .028]. iGlarLixi was also superior to BIAsp 30 for HbA1c reduction (p = .010). A greater proportion of participants achieved HbA1c <7% without weight gain and HbA1c <7% without weight gain and without hypoglycaemia with iGlarLixi versus BIAsp 30. Incidence and rates of American Diabetes Association Level 1 and 2 hypoglycaemia were lower with iGlarLixi versus BIAsp 30. CONCLUSIONS: Once-daily iGlarLixi provided better glycaemic control with weight benefit and less hypoglycaemia than twice-daily premix BIAsp 30. iGlarLixi may be a favourable alternative to premix BIAsp 30 in people with suboptimally controlled T2D to advance BI therapy in the LATAM region.

RESUMO

Introducción: La diabetes mellitus (DM) es una enfermedad crónica inflamatoria muy frecuente y por ende una de las emergencias sanitarias mundiales de más rápido crecimiento en las últimas décadas. Hay tres ejes que impactan en la progresión del compromiso renal del paciente diabético. El eje hemodinámico, metabólico e inflamatorio. Resaltamos la importancia del componente inflamatorio como actor protagónico en el desarrollo de la Enfermedad renal diabética (ERD). El manejo del paciente con ERD debe ser holístico, con tres objetivos claros: buen control metabólico, disminuir progresión de la enfermedad renal y disminuir los desenlaces cardiovasculares adversos. Actualmente además de las intervenciones no farmacológicas, el control de los factores de riesgo, el uso de los IECAS/ARA II hay nuevos pilares en el tratamiento de la ERD. Objetivos: El objetivo de esta comunicación es revisar los nuevos pilares en el manejo de la ERD. En la revisión bibliográfica que se hizo, encontramos que hay tres nuevos pilares en el tratamiento. Los inhibidores SGLT-2, los agonistas del receptor GLP-1 y por último finerenona, que es un antagonista selectivo no esteroideo del receptor mineralocorticoide (ARM), no es un antidiabético. Con estas nuevas terapias el manejo actual de estos pacientes ha cambiado considerablemente. Conclusión: Hay nuevos pilares en el tratamiento de la ERD. Los inhibidores SGLT-2, los Agonistas del receptor GLP-1 y el uso de ARM como finerenona, que nos brindan beneficios cardio­renales y que hacen que hoy en día el tratamiento de la ERD tenga un mejor panorama.


Introduction: Diabetes mellitus (DM) is a very common chronic inflammatory disease and finally one of the fastest-growing global health emergencies in recent decades. Three axes impact the progression of renal compromise in diabetic patients. The hemodynamic, metabolic, and inflammatory axis. We highlight the importance of the inflammatory component as a leading actor in developing Diabetic Kidney Disease (DKD). The management of the patient with CKD must be holistic, with three clear objectives: reasonable metabolic control, slowing the progression of kidney disease, and reducing adverse cardiovascular outcomes. Currently, in addition to non-pharmacological interventions, the control of risk factors, and the use of ACE inhibitors/ARA II, there are new pillars in the treatment of CKD. Objectives: The objective of this communication is to review the new pillars in the management of DKD. In the bibliographic review that was carried out, we found that there are three new pillars in the treatment. SGLT-2 inhibitors, GLP-1 receptor agonists, and finally finerenone, which is a selective non-steroidal antagonist of the mineralocorticoid receptor (MRA), not an antidiabetic. With these new therapies, the current management of these patients has changed considerably. Conclusion: There are new pillars in the treatment of DKD. The SGLT-2 inhibitors, the GLP-1 receptor agonists, and the use of MRAs such as finerenone provide us with cardio-renal benefits and which today make the treatment of CKD have a better outlook.
