RESUMO

Bariatric surgery was initially developed as a tool for weight reduction only, but it is gaining popularity because of its remarkable effect on glucose metabolism in morbidly obese and less obese patients. Recent publications have shown the superiority of metabolic surgery over medical treatment for diabetes, creating a new field of clinical research that is currently overflowing in the medical community with outstanding high-quality data. Metabolic surgery is effective in treating diabetes, even in non-morbidly obese patients.

RESUMO

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.

RESUMO

OBJECTIVE: To establish recommendations through the consensus of a Latin American experts panel on the use of the flash glucose monitoring system (fCGM) in people living with type 2 diabetes mellitus (T2DM) regarding the benefits and challenges of using the fCGM. METHODS: An executive committee of experts was created, comprised by a panel of fifteen physicians, including endocrinologists and internal medicine physicians, with expertise in management of adult patients with T2DM. The experts were from various countries: Colombia, Chile, Peru, Mexico, Argentina, and Brazil. The modified Delphi method was used, considering a consensus level of at least 80% of the participants. A seventeen-item instrument was developed to establish recommendations on the use of fCGM in patients with T2DM in Latin American. RESULTS: The number of glucose scans recommended per day with the fCGM for patients managed with oral antidiabetic drugs or basal insulin was a median of 6 scans per day, and for those managed with multiple insulin doses, a median of 10 scans per day was recommended. Additionally, a holistic and individualized management approach was recommended, taking into account new treatment directions and identifying patients who would benefit from the use of the fCGM. CONCLUSION: Continuous use of the fCGM is recommended for people living with T2DM, regardless of their type of treatment. These metrics must be evaluated individually for each patient profile.

RESUMO

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.

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

The epidemic of obesity or adiposity-based chronic diseases presents a significant challenge with the rising prevalence of morbidities and mortality due to atherosclerotic cardiovascular diseases (ASCVD), especially in low- and middle-income countries (LMIC). The underlying pathophysiology of metabolic inflexibility is a common thread linking insulin resistance to cardiometabolic-based chronic disease (CMBCD), including dysglycemia, hypertension, and dyslipidemia progressing to downstream ASCVD events. The complex CMBCD paradigm in the LMIC population within the socio-economic and cultural context highlights considerable heterogeneity of disease predisposition, clinical patterns, and socio-medical needs. This review intends to summarize the current knowledge of CMBCD. We describe recently established or emerging trends for managing risk factors, assessment tools for evaluating ASCVD risk, and various pharmacological and non-pharmacological measures particularly relevant for LMICs. A CMBCD model positions insulin resistance and ß-cell dysfunction at the summit of the disease spectrum may improve outcomes at a lower cost in LMICs. Despite identifying multiple pathophysiologic disturbances constituting CMBCD, a large percentage of the patient at risk for ASCVD remains undefined. Targeting dysglycemia, dyslipidemia, and hypertension using antihypertensive, statins, anti-glycemic, and antiplatelet agents has reduced the incidence of ASCVD. Thus, primordial prevention targeting pathophysiological changes that cause abnormalities in adiposity and primary prevention by detecting and managing risk factors remains the foundation for CMBCD management. Therefore, targeting pathways that address mitochondrial dysfunction would exert a beneficial effect on metabolic inflexibility that may potentially correct insulin resistance, ß cell dysfunction and, consequently, would be therapeutically effective across the entire continuum of CMBCD.

RESUMO

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).

RESUMO

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

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.

RESUMO

BACKGROUND/AIM: In several populations, major histocompatibility complex and CTLA-4 (cytotoxic T lymphocyte antigen-4) gene polymorphisms are related to adult subjects with Graves' disease (GD). Our aim was to study the association of +49A>G polymorphism of the CTLA-4 gene in Brazilian children and adults with GD and its correlation with clinical and laboratory markers of disease severity. METHODS: CTLA-4 +49A>G polymorphism was established by polymerase chain reaction-restriction fragment length polymorphism analysis in 44 children and 72 adults with GD and compared to a stringent control group consisting of octogenarians with no history of thyroid disease; free T4 and T3 levels and T3/T4 ratio, antithyroid antibodies, and Graves' ophthalmopathy were also evaluated according to genotype. RESULTS: No significant difference was found in the frequency of CTLA-4 +49A>G polymorphism among children and adults with GD compared to controls and within groups. There was no significant correlation between the presence of G allele and Graves' ophthalmopathy, gender, age at diagnosis, and biochemical markers of disease severity. CONCLUSION: The frequency of CTLA-4 +49A>G polymorphism is not different in children and adults with GD compared to the normal control population and does not seem to contribute independently to the severity of the clinical presentation of GD.

RESUMO

AIMS: We aimed to explore insulin initiation barriers in the Brazilian Type 2 Diabetes Mellitus (T2DM) elderly population, according to the physician's perspective, and suggest strategies to overcome them. METHODS: A 45-questions survey addressing issues as clinical characteristics, barriers to insulinization, and treatment strategies in elderly patients with T2DM, was sent to six endocrinologists from different Brazilian locations. Thereafter, all the respondents participated in a panel discussion to validate their responses and collect additional relevant data. RESULTS: Endocrinologists had at least 15 years of experience, with a mean of 63 elderly patients per month. Nearly 25% of the elderly patients were treated in the Brazilian public healthcare system (SUS, Unified Health System); only a quarter presented proper glycemic control. In contrast, 55% of the patients from private healthcare system presented adequate glycemic control. The main barriers for insulin initiation for patients, according to physicians' perspective, are side effects and negative perception over treatment (100%). For endocrinologists, main barriers were lack of time to guide patients and concern over side effects (83%). Therefore, specialists considered education for both healthcare professionals and patients as one of the most important strategies to circumvent the current scenario related insulin therapy among elderly patients in the country. CONCLUSION: Insulin therapy remains underused due to several barriers, such as concern over side effects and negative perception. Educational measures for patients and HCPs could improve the current scenario.

RESUMO

UNLABELLED: Maternal inherited diabetes and deafness (MIDD) has been related to an A to G transition in the mitochondrial RNA Leu (UUR) at base pair 3243. The prevalence of MIDD in the diabetes population ranges between 0.5-3.0% depending on the ethnic background. AIM: To examine the frequency and clinical features of diabetes associated with this mutation in Brazilian patients with glucose intolerance. METHODS: The study population comprised: 78 type 1 diabetic subjects (group I), 148 patients with type 2 diabetes (group II), 15 patients with either type 1 or type 2 diabetes and hearing loss (group III) and 492 Japanese Brazilians with varying degrees of glucose intolerance. DNA was extracted from peripheral blood leucocytes and the A3243G mutation was determined by PCR amplification and Apa 1 digestion. In some individuals DNA was also extracted from buccal mucosa and hair follicles. The 3243 bp mutation was found in three individuals, all from group III, resulting in a prevalence of 0.4%. These subjects had an early age of diagnosis of diabetes, low or normal body mass index and requirement of insulin therapy. In conclusion MIDD is rare in our population and should be investigate in patients with diabetes and deafness.

RESUMO

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.

RESUMO

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.

RESUMO

Maternally-inherited diabetes and deafness (MIDD) has been related to an A to G transition in the mitochondrial tRNA Leu (UUR) gene at the base pair 3243. Although some previous articles have reported that this mutation may be a cause of cardiomyopathy in diabetes, the degree of cardiac involvement and a specific treatment has not been established. Here, we reported a case of a patient with MIDD who developed congestive heart failure and the therapeutic usefulness of Coenzyme Q10 (CoQ10). In our patient, after the introduction of Coenzyme Q10 150 mg/day, there was a gradual improvement on left ventricular function evaluated by echocardiography. The fractional shortening (FS) and ejection fraction (EF) increased from 26 to 34% and from 49 to 64%, respectively. No side effects were noted. Three months after CoQ10 discontinuation, the parameters of systolic function evaluated by echocardiography decreased, suggesting that CoQ10 had a beneficial effect. Identification of diabetes and cardiomyopathy due to mitochondrial gene mutation may have therapeutic implications and Coenzyme Q10 is a possible adjunctive treatment in such patients.

RESUMO

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.

ABSTRACT Objective: The main aim of the study was to evaluate the patients' glycemic control and adherence to self-care tasks. Materials and 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).

RESUMO

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.

RESUMO

CONTEXT: The duodenal-jejunal bypass liner (DJBL) is a device that mimics the intestinal portion of gastric bypass surgery and has been shown to improve glucose metabolism rapidly in obese subjects with type 2 diabetes (T2DM). OBJECTIVE: To assess the safety of the DJBL and to evaluate its potential to affect glycemic control beneficially in subjects with T2DM who were not morbidly obese. PATIENTS AND DESIGN: Adult men and women with T2DM of ≤ 10 years' duration with hemoglobin A1c (HbA1c) ≥ 7.5% and ≤ 10% and having a body mass index ≥ 26 to ≤ 50 kg/m(2) were enrolled in this prospective, 52-week, single-center, open-label clinical study. MAIN OUTCOME MEASURES: Adverse events and changes in body weight, fasting plasma glucose (FPG) levels, and HbA1c levels. RESULTS: Sixteen of 20 subjects implanted with the DJBL completed the 1-year study (mean body mass index = 30.0 ± 3.6, mean ± SD). Gastrointestinal disorders were reported by 13 subjects, and metabolic or nutritional disorders occurred in 14 subjects. FPG levels dropped from 207 ± 61 mg/dL at baseline to 139 ± 37 mg/dL at 1 week and remained low throughout the study. Mean body weight also declined, but the change in body weight was not significantly associated with change in FPG at 52 weeks. HbA1c declined from 8.7 ± 0.9% at baseline to 7.5 ± 1.6% at week 52. CONCLUSIONS: The improvements in glycemic status were observed at 1 year in moderately obese subjects with T2DM, suggesting that the DJBL may represent an effective adjuvant to standard medical therapy of T2DM in this population.
