RESUMEN
INTRODUCTION: Type 2 diabetes mellitus (T2DM) is associated with dysbiosis in the gut microbiota (MB). Individually, each medication appears to partially correct this. However, there are no studies on the response of the MB to changes in A1c. Therefore, we investigated the MB's response to intensive glycemic control. RESEARCH DESIGN AND METHODS: We studied two groups of patients with uncontrolled T2DM, one group with an A1c <9% (18 patients-G1) and another group with an A1c >9% (13 patients-G2), aiming for at least a 1% reduction in A1c. We collected A1c and fecal samples at baseline, 6, and 12 months. G1 achieved an average A1c reduction of 1.1%, while G2 a reduction of 3.13%. RESULTS: G1's microbiota saw a decrease in Erysipelotrichaceae_UCG_003 and in Mollicutes order (both linked to metabolic syndrome and associated comorbidities). G2, despite having a more significant reduction in A1c, experienced an increase in the proinflammatory bacteria Megasphaera and Acidaminococcus, and only one beneficial genus, Phascolarctobacterium, increased, producer of butyrate. CONCLUSION: Despite a notable A1c outcome, G2 could not restore its MB. This seeming resistance to change, leading to a persistent inflammation component found in G2, might be part of the "metabolic memory" in T2DM.

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.
RESUMEN
OBJECTIVES: To evaluate the effect of whey protein (WP) supplementation associated with resistance training (RT) on glycemic control, functional tasks, muscle strength, and body composition in older adults living with type 2 diabetes mellitus (T2DM). Secondly, to evaluate the safety of the protocol for renal function. METHODS: The population comprised twenty-six older men living with T2DM (68.5 ± 11.5 years old). The participants were randomly assigned to the Protein Group (PG) and the Control Group (CG). The handgrip test and evolution of exercise loads, according to the Omni Resistance Exercise Scale, evaluated muscle strength. Functional tasks were assessed by force platform in three different protocols: Sit-to-Stand, Step/Quick Turn, and Step Up/Over. Body composition was evaluated by bioimpedance and glycemic control and renal function were assessed by biochemical analyses. Both groups performed RT for 12 weeks, twice a week, prioritizing large muscle groups. Protein supplementation was 20 g of whey protein isolate and the CG was supplemented with an isocaloric drink, containing 20 g of maltodextrin. RESULTS: There was a significant difference in muscle strength, according to the evolution of the exercise loads, but it was not confirmed in the handgrip test. However, there was no significant difference between the groups, regarding performance in functional tasks, glycemic control, or body composition. Renal function showed no alteration. CONCLUSION: The intake of 20 g of WP in older male adults living with T2DM did not increase the effect of RT on muscle strength, functional tasks, and glycemic control. The intervention was proven safe regarding renal function.

OBJECTIVE: The main aim of the study was to evaluate the patients' glycemic control and adherence to self-care tasks. METHODS: Patients with type 1 diabetes mellitus (T1DM) or latent autoimmune diabetes of the adult (LADA) using a multiple daily injection (MDI) regimen with carbohydrate counting (n = 25, Subgroup B) or fixed insulin dose (n = 25, Subgroup C) were allocated to use the application (app) for 12 weeks. Both subgroups were compared with each other and against a control group (n = 25, Group A) comprising patients with T1DM or LADA treated with continuous subcutaneous insulin infusion (CSII) in a parallel-group, open-label, clinical treatment trial. All patients had glycated hemoglobin (A1C) levels measured and were asked to fill out the Diabetes Self-Management Profile (DSMP) questionnaire at study start and end. The patients were instructed to measure capillary glucose six times daily in study weeks 4, 8, and 12. RESULTS: Mean A1C levels decreased 0.725% in Subgroup C in intragroup analysis (p = 0.0063), and had a mean variation of 0.834% compared with Group A (p = 0.003). Mean DSMP scores increased 5.77 points in Subgroup B in intragroup analysis (p = 0.0004) and increased by a mean of 6.815 points in relation to Group A (p = 0.002). CONCLUSION: OneTouch Reveal improved both A1C levels and DSMP scores in patients with T1DM or LADA compared with standard treatment (CSII).

BACKGROUND: In current management of type 2 diabetes (T2DM), cardiovascular and renal prevention have become important targets to be achieved. In this context, a joint panel of four endocrinology societies from Brazil and Portugal was established to develop an evidence-based guideline for treatment of hyperglycemia in T2DM. METHODS: MEDLINE (via PubMed) was searched for randomized clinical trials, meta-analyses, and observational studies related to diabetes treatment. When there was insufficient high-quality evidence, expert opinion was sought. Updated positions on treatment of T2DM patients with heart failure (HF), atherosclerotic CV disease (ASCVD), chronic kidney disease (CKD), and patients with no vascular complications were developed. The degree of recommendation and the level of evidence were determined using predefined criteria. RESULTS AND CONCLUSIONS: In non-pregnant adults, the recommended HbA1c target is below 7%. Higher levels are recommended in frail older adults and patients at higher risk of hypoglycemia. Lifestyle modification is recommended at all phases of treatment. Metformin is the first choice when HbA1c is 6.5-7.5%. When HbA1c is 7.5-9.0%, dual therapy with metformin plus an SGLT2i and/or GLP-1RA (first-line antidiabetic agents, AD1) is recommended due to cardiovascular and renal benefits. If an AD1 is unaffordable, other antidiabetic drugs (AD) may be used. Triple or quadruple therapy should be considered when HbA1c remains above target. In patients with clinical or subclinical atherosclerosis, the combination of one AD1 plus metformin is the recommended first-line therapy to reduce cardiovascular events and improve blood glucose control. In stable heart failure with low ejection fraction (< 40%) and glomerular filtration rate (eGFR) > 30 mL/min/1.73 m2, metformin plus an SGLT-2i is recommended to reduce cardiovascular mortality and heart failure hospitalizations and improve blood glucose control. In patients with diabetes-associated chronic kidney disease (CKD) (eGFR 30-60 mL/min/1.73 m2 or eGFR 30-90 mL/min/1.73 m2 with albuminuria > 30 mg/g), the combination of metformin and an SGLT2i is recommended to attenuate loss of renal function, reduce albuminuria and improve blood glucose control. In patients with severe renal failure, insulin-based therapy is recommended to improve blood glucose control. Alternatively, GLP-1RA, DPP4i, gliclazide MR and pioglitazone may be considered to reduce albuminuria. In conclusion, the current evidence supports individualizing anti-hyperglycemic treatment for T2DM.
RESUMEN
Diabetes mellitus (DM) is an increasingly prevalent condition that has a significant impact on health systems worldwide, particularly in older people. It is estimated that 30% of people aged > 65 years fulfil the diagnostic criteria for DM, with 90% having type 2 DM (T2DM). Generally, specific guidelines for the treatment of T2DM in older people address in a very limited manner the use of more recent therapies, such as sodium-glucose co-transporter-2 inhibitors (SGLT2i), which have important benefits for older people, such as a low risk of hypoglycemia, reduction of cardiovascular and renal risk, and an insulin-independent mechanism, allowing its use in disease of any duration. The SGLT2i class is well-tolerated, though some caution is also suggested, including adjustment of concomitant therapies, such as insulin and antihypertensives, especially loop diuretics. This review discusses the pathophysiological characteristics of the older patient with T2DM and evaluates the main benefits of and cautions for the use of SGLT2i in this population.

Resumo Fundamentação: desde o primeiro posicionamento da Sociedade Brasileira de Diabetes (SBD) sobre diabetes e prevenção cardiovascular, em 2014,1 importantes estudos têm sido publicados na área de prevenção cardiovascular e tratamento do diabetes,2 os quais contribuíram para a evolução na prevenção primária e secundária nos pacientes com diabetes. Ferramentas de estratificação de risco mais precisas, novos fármacos hipolipemiantes e novos antidiabéticos com efeitos cardiovasculares e redução da mortalidade, são parte desta nova abordagem para os pacientes com diabetes. O reconhecimento de que o diabetes é uma doença heterogênea foi fundamental, sendo claramente demonstrado que nem todos os pacientes diabéticos pertencem a categorias de risco alto ou muito alto. Um porcentual elevado é composto por pacientes jovens, sem os fatores de risco clássicos, os quais podem ser classificados adequadamente em categorias de risco intermediário ou mesmo em baixo risco cardiovascular. O presente posicionamento revisa as melhores evidências atualmente disponíveis e propõe uma abordagem prática, baseada em risco, para o tratamento de pacientes com diabetes. Estruturação: perante este desafio e reconhecendo a natureza multifacetada da doença, a SBD uniu-se à Sociedade Brasileira de Cardiologia (SBC) e à Sociedade Brasileira de Endocrinologia e Metabolismo (SBEM), e formou um painel de especialistas, constituído por 28 cardiologistas e endocrinologistas, para revisar as melhores evidências disponíveis e elaborar uma diretriz contendo recomendações práticas para a estratificação de risco e prevenção da Doença Cardiovascular (DVC) no Diabetes Melito (DM). As principais inovações incluem: (1) considerações do impacto de novos hipolipemiantes e das novas medicações antidiabéticas no risco cardiovascular; (2) uma abordagem prática, baseada em fator de risco, para orientar o uso das estatinas, incluindo novas definições das metas da Lipoproteína de Baixa Densidade-colesterol (LDL-colesterol) e colesterol não Lipoproteína de Alta Densidade HDL; (3) uma abordagem baseada em evidências, para avaliar a isquemia miocárdica silenciosa (IMS) e a aterosclerose subclínica em pacientes com diabetes; (4) as abordagens mais atuais para o tratamento da hipertensão; e (5) recomendação de atualizações para o uso de terapia antiplaquetária. Esperamos que esta diretriz auxilie os médicos no cuidado dedicado aos pacientes com diabetes. Métodos: inicialmente, os membros do painel foram divididos em sete subcomitês para definirem os tópicos principais que necessitavam de uma posição atualizada das sociedades. Os membros do painel pesquisaram e buscaram no PubMed estudos clínicos randomizados e metanálises de estudos clínicos e estudos observacionais de boa qualidade, publicados entre 1997 e 2017, usando termos MeSH: [diabetes], [diabetes tipo 2], [doença cardiovascular], [estratificação de risco cardiovascular] [doença arterial coronária], [rastreamento], [isquemia silenciosa], [estatinas], [hipertensão], [ácido acetilsalicílico]. Estudos observacionais de baixa qualidade, metanálises com alta heterogeneidade e estudos transversais não foram incluídos, embora talvez tenham impactado no Nível de Evidência indicado. A opinião de especialistas foi usada quando os resultados das buscas não eram satisfatórios para um item específico. É importante salientar que este posicionamento não teve a intenção de incluir uma revisão sistemática rigorosa. Um manuscrito preliminar, destacando recomendações de graus e níveis de evidência (Quadro 1), foi esboçado. Este passo levou a várias discussões entre os membros dos subcomitês, que revisaram os achados e fizeram novas sugestões. O manuscrito foi, então, revisto pelo autor líder, encarregado da padronização do texto e da inclusão de pequenas alterações, sendo submetido à apreciação mais detalhada pelos membros dos comitês, buscando uma posição de consenso. Depois desta fase, o manuscrito foi enviado para a banca editorial e edição final, sendo encaminhado para publicação. Quadro 1 Graus de recomendações e níveis de evidências adotados nesta revisão Grau de recomendação Classe I A evidência é conclusiva ou, se não, existe consenso de que o procedimento ou tratamento é seguro e eficaz Classe II Há evidências contraditórias ou opiniões divergentes sobre segurança, eficácia, ou utilidade do tratamento ou procedimento Classe IIa As opiniões são favoráveis ao tratamento ou procedimento. A maioria dos especialistas aprova Classe IIb A eficácia é bem menos estabelecida, e as opiniões são divergentes Classe III Há evidências ou consenso de que o tratamento ou procedimento não é útil, eficaz, ou pode ser prejudicial Níveis de Evidência A Múltiplos estudos clínicos randomizados concordantes e bem elaborados ou metanálises robustas de estudos clínicos randomizados B Dados de metanálises menos robustas, um único estudo clínico randomizado ou estudos observacionais C Opinião dos especialistas

BACKGROUND: Since the first position statement on diabetes and cardiovascular prevention published in 2014 by the Brazilian Diabetes Society, the current view on primary and secondary prevention in diabetes has evolved as a result of new approaches on cardiovascular risk stratification, new cholesterol lowering drugs, and new anti-hyperglycemic drugs. Importantly, a pattern of risk heterogeneity has emerged, showing that not all diabetic patients are at high or very high risk. In fact, most younger patients who have no overt cardiovascular risk factors may be more adequately classified as being at intermediate or even low cardiovascular risk. Thus, there is a need for cardiovascular risk stratification in patients with diabetes. The present panel reviews the best current evidence and proposes a practical risk-based approach on treatment for patients with diabetes. MAIN BODY: The Brazilian Diabetes Society, the Brazilian Society of Cardiology, and the Brazilian Endocrinology and Metabolism Society gathered to form an expert panel including 28 cardiologists and endocrinologists to review the best available evidence and to draft up-to-date an evidence-based guideline with practical recommendations for risk stratification and prevention of cardiovascular disease in diabetes. The guideline includes 59 recommendations covering: (1) the impact of new anti-hyperglycemic drugs and new lipid lowering drugs on cardiovascular risk; (2) a guide to statin use, including new definitions of LDL-cholesterol and in non-HDL-cholesterol targets; (3) evaluation of silent myocardial ischemia and subclinical atherosclerosis in patients with diabetes; (4) hypertension treatment; and (5) the use of antiplatelet therapy. CONCLUSIONS: Diabetes is a heterogeneous disease. Although cardiovascular risk is increased in most patients, those without risk factors or evidence of sub-clinical atherosclerosis are at a lower risk. Optimal management must rely on an approach that will cover both cardiovascular disease prevention in individuals in the highest risk as well as protection from overtreatment in those at lower risk. Thus, cardiovascular prevention strategies should be individualized according to cardiovascular risk while intensification of treatment should focus on those at higher risk.
RESUMEN
INTRODUCTION: Metabolic syndrome (MS) is characterized by dyslipidemia, central obesity, hypertension and hyperglycemia. However, type 2 diabetes mellitus (T2DM) may or may not be present in metabolic syndrome. MS and T2DM are considered important cardiovascular risk factors, but the role of hyperglycemia in coronary disease is still contested in the literature. Therefore, we decided to evaluate the effect of hyperglycemia on the severity of coronary disease in MS patients, with or without T2DM, submitted to coronary angiography (CA) and intravascular ultrasonography (IVUS). MATERIALS AND METHODS: This is a cross sectional, observational study with 100 MS patients (50% with T2DM), 60% male. All of the patients had been referred for CA procedures. The obstruction was considered severe when stenosis was greater than 70% and moderate if it was between 50-69%. Patients detected with a moderate obstruction by CA were indicated to IVUS. A minimal luminal area of less than 4mm2 detected by IVUS was also considered severe. IDF criteria were used to define Metabolic Syndrome and T2DM diagnosis was defined according to the American Diabetes Association criteria. Student's t-test and Pearson Chi-square were used for statistical analysis, considering p < 0.05 statistically significant. RESULTS AND DISCUSSION: The majority of T2DM patients presented severe arterial lesions (74% vs 22%, p<0.001). Using CA procedure, 12% of T2DM had moderate obstructions, compared to 38% of the non-diabetic group (p< 0.05). 8% of patients with moderate lesions by CA were diagnosed with a luminal area less than 4mm2 using IVUS. This luminal area was significantly smaller in the T2DM group than in the control group (3.8mm2 ± 2.42. vs 4.6mm2 ± 2.58, p = 0.03). CONCLUSION: Patients with MS and T2DM submitted to angiography and IVUS, had more severe coronary lesions compared to MS patients without diabetes. This finding suggests that beyond insulin resistance that is present in MS, hyperglycemia may also play a role in the development of atherosclerotic disease. IVUS was useful for diagnosing 8% of severe cases initially considered to be moderate obstructions when using just CA in this scenario.

BACKGROUND: Type 2 diabetes mellitus (DM) globally affects 18-20 % of adults over the age of 65 years. Diabetic kidney disease (DKD) is one of the most frequent and dangerous complications of DM2, affecting about one-third of the patients with DM2. In addition to the pancreas, adipocytes, liver, and intestines, the kidneys also play an important role in glycemic control, particularly due to renal contribution to gluconeogenesis and tubular reabsorption of glucose. METHODS: In this review article, based on a report of discussions from an interdisciplinary group of experts in the areas of endocrinology, diabetology and nephrology, we detail the relationship between diabetes and kidney disease, addressing the care in the diagnosis, the difficulties in achieving glycemic control and possible treatments that can be applied according to the different degrees of impairment. DISCUSSION: Glucose homeostasis is extremely altered in patients with DKD, who are exposed to a high risk of both hyperglycemia and hypoglycemia. Both high and low glycemic levels are associated with increased morbidity and shortened survival in this group of patients. Factors that are associated with an increased risk of hypoglycemia in DKD patients include decreased renal gluconeogenesis, deranged metabolic pathways (including altered metabolism of medications) and decreased insulin clearance. On the other hand, decrease glucose filtration and excretion, and inflammation-induce insulin resistance are predisposing factors to hyperglycemic episodes. CONCLUSION: Appropriate glycaemic monitoring and control tailored for diabetic patients is required to avoid hypoglycaemia and other glycaemic disarrays in patients with DM2 and kidney disease. Understanding the renal physiology and pathophysiology of DKD has become essential to all specialties treating diabetic patients. Disseminating this knowledge and detailing the evidence will be important to initiate breakthrough research and to encourage proper treatment of this group of patients.
RESUMEN
INTRODUÇÃO: O Diabetes Mellitus (DM) consiste em uma doença crônica ocasionada pela hiperglicemia. Sabe-se que essa patologia esta presente em aproximadamente 10% das internações hospitalares, e que uma porcentagem significativa dos pacientes com Diabetes Mellitus apresenta-se sem diagnóstico prévio no momento da internação. A hiperglicemia pode provocar efeitos deletérios no organismo como processo inflamatório. OBJETIVO: Avaliar a HbA1c como ferramenta diagnóstica e preditiva da evolução clínica de pacientes com e sem diagnóstico de Diabetes Mellitus, avaliada durante período de internação hospitalar e sua relação com as complicações hospitalares. MÉTODOS: Foram avaliados 100 pacientes no período de um ano e verificado através do protocolo Institucional NUMAD (Núcleo de assistência ao Paciente Diabético) os valores de hemoglobina glicada HbA1c em pacientes com hiperglicemia. RESULTADOS: Os pacientes sem diagnóstico prévio de Diabetes Mellitus apresentaram HbA1c entre 5,8% e 7,5%, com a mediana do tempo de internação de 9 dias, sem complicações. Os pacientes com Diabetes Mellitus que evoluíram com complicações, apresentaram HbA1c entre 7,3% e 12,4% e correspondiam a 20% do estudo, com tempo de internação de 34,5 dias. DISCUSSÃO: Estudos descrevem a prevalência de hiperglicemia relacionada a mortalidade e período de internação hospitalar, e principalmente em relação a hemoglobina glicada como marcador de gravidade independente da patologia. Nosso estudo demonstrou a importância dessa ferramenta como um aliado ao tratamento hospitalar. CONCLUSÃO: A HbA1c demonstrou em nosso estudo ser um marcador prognóstico e preditivo importante em pacientes com hiperglicemia hospitalar.
INTRODUCTION: Diabetes Mellitus (DM) is a chronic disease caused by hyperglycemia. It is known that this disease is present in approximately 10% of hospital admissions, and there is a significant percentage of patients with Diabetes Mellitus presents with no previous diagnosis at admission. Hyperglycemia can cause deleterious effects in the body as an inflammatory process. OBJECTIVE: To evaluate the HbA1c as a diagnostic and predictive tool outcome of patients with and without diagnosis of Diabetes Mellitus, performed during hospital stay and its relation with the hospital complications. METHODS: A total of 100 patients in the period of a year and verified by the Institutional NUMAD protocol (service core to Diabetic Patients) the glycated hemoglobin HbA1c in patients with hyperglycemia. RESULTS: Patients with no previous diagnosis of Diabetes Mellitus had HbA1c between 5.8% and 7.5%, with the median length of stay of nine days without complications. Patients with Diabetes Mellitus who developed complications, had HbA1c between 7.3% and 12.4% and accounted for 20% of the study, with hospital stay of 34.5 days. DISCUSSION: Studies describe the prevalence of hyperglycemia related mortality and hospital stay, and especially in relation to glycated hemoglobin as a marker of severity regardless of pathology. Our study demonstrated the importance of this tool as an ally to the hospital treatment. CONCLUSION: HbA1c demonstrated in our study to be a prognostic and predictive marker important in patients with hospital hyperglycemia.

There is a very well known correlation between diabetes and cardiovascular disease but many health care professionals are just concerned with glycemic control, ignoring the paramount importance of controlling other risk factors involved in the pathogenesis of serious cardiovascular diseases. This Position Statement from the Brazilian Diabetes Society was developed to promote increased awareness in relation to six crucial topics dealing with diabetes and cardiovascular disease: Glicemic Control, Cardiovascular Risk Stratification and Screening Coronary Artery Disease, Treatment of Dyslipidemia, Hypertension, Antiplatelet Therapy and Myocardial Revascularization. The issue of what would be the best algorithm for the use of statins in diabetic patients received a special attention and a new Brazilian algorithm was developed by our editorial committee. This document contains 38 recommendations which were classified by their levels of evidence (A, B, C and D). The Editorial Committee included 22 specialists with recognized expertise in diabetes and cardiology.
