Tratamiento no farmacológico de la diabetes mellitus tipo 2. Cirugía de la obesidad. Nuevas estrategias terapéuticas

The incidence and prevalence of type 2 diabetes mellitus (DM2) and obesity are increasing globally and are closely interrelated. Obesity surgery (metabolic surgery) is a valid, effective tool for weight reduction and remission of DM2. This update describes the different surgical techniques in obesity surgery. It also lists the available evidence on the observational studies and clinical trials that have supported recommendations for this intervention in patients with DM2 and obesity. Lastly, emerging treatment strategies related to peptides involved with the incretin effect (GLP-1, GIP, and glucagon) and glucose receptor inhibitors (SGLT) are described.

Analysis of quality of life in patients with clinically severe obesity and type 2 diabetes mellitus after laparoscopic sleeve gastrectomy – a 12-month prospective observational study

<b>Introduction:</b> Due to a short history of laparoscopic sleeve gastrectomy (LSG) as an independent bariatric procedure, we still lack studies providing analysis of the quality of life (QoL) in patients with type 2 diabetes mellitus (DM2).<b>Aim:</b> We aimed to assess the influence of LSG on QoL in obese patients with DM2.<b>Material and Methods:</b> Prospective, observational study included patients with: morbid obesity; BMI ≥35 kg/m and ≤50 kg/m, DM2 shorter than 10 years; qualified for LSG. Bariatric Analysis and Reporting Outcome System (BAROS) that included the MA-QoLQII score, and the SF-36 questionnaire were used for repetitive assessment of QoL before LSG and after 1 and 12 months following surgery. Selected clinical and biochemical parameters were also repeatedly measured.<b>Results:</b> Thirty-three patients were included in the study (23 females). Patients’ mean age was 4510 years. BAROS significantly increased before LSG, 1 month, and 1 year after surgery (0.631.12; 2.941.90, and 4.972.08, respectively). The MA-QoLQII score significantly rose with an increase of EBMIL (P=0.002) and remission of DM2 (P=0.049), while inversely correlated with HOMA-IR (P=0.003). Degenerative joint disease (P=0.025) and average time of low glucose concentration in Continuous Glucose Monitoring (CGM) (P=0.005) had an inverse correlation with SF-36 Physical Component Summaries, standardized for cardiovascular comorbidity, EBMIL and HOMA-IR (P=0.839; P=0.086; P=0.571, respectively). EBMIL (P=0.003), remission of DM2 (P<0.001) had a positive correlation with MCS, while HOMA-IR (P<0.001) and count of low glucose concentration events (P=0.022) had an inverse correlation with Mental Component Summaries, while standardized for average glucose concentration in CGM after 12 months (P=0.586).<b>Discussion:</b> Significant improvement in QoL was observed in patients with DM2 after LSG. Remission of DM2, higher EBMIL, lower HOMA-IR, less and shorter low glucose concentration events in CGM after 12 months were factors that increased selected QoL scores.

Comparative Study between the Effect of Single Anastomosis Gastric Bypass versus Roux-en-Y Gastric Bypass in Morbidly Obese Patient as Regard Remission of Type-2 DM

Abstract Background Accumulating evidence obviously supports the superiority of weight loss surgery over non-surgical treatments for management of morbidly obese patients in terms of outcomes as sustained weight loss, improved quality of life and prevention, reduction, or resolution of comorbidities (e.g., Type 2 Diabetes Mellitus, dyslipidemia), as well as reduced overall mortality. Objective To compare Type 2 DM remission as well as the metabolic effects of 2 types of bariatric surgery; Single Anastomosis gastric Bypass and Roux-en-Y Gastric bypass, in the first year postoperative follow up in relation to DiaRem Scoring system. Patients and Methods This is a prospective randomized clinical trial study conducted in AinShams University Hospitals bariatric surgery unit over 40 patients with minimal follow-up of 12 months. 2 groups of patients: Group A: composed of 20 patients that undergoing OAGB as a metabolic surgery for control of Type 2 DM. Group B: composed of 20 patients that undergoing Reux-en-Y gastric bypass as a metabolic surgery for control of Type 2 DM. Patients were randomly distributed among both groups using simple randomization odds and evens where odd patients were included in group A and even patients were included in group B. Results We find that Roux-en-Y operation is more potent as regard remission of DM than MGB/OAGB (80% versus 65%) and that remission of DM depends on diabetes itself (duration, HBA1C, C-PEPTIDE) and these are the main determinants of remission. And DiaRem score is good predictor of DM remission in low scoring categories however in high scoring categories it is poor in prediction of DM remission Conclusion No statistical difference between both groups as regard remission of DM however numerically it is obvious that Roux-en-Y is more potent metabolic surgery in order to be statistically significant the study needs to be repeated over larger sample size. The main determinant noticed during the study influencing remission is the duration of DM and preoperative C-peptide level-in addition to HBA1C level. We must put into our consideration the post operative complications of MGB/OAGB as regard biliary reflux and failure which are more less in Roux-enY operation but in order to be evaluated longer duration of follow up is needed. We recommend Roux-en-Y as a metabolic surgery for patients with early onset DM type II with BMI ranging from 30-40. The study needs to be repeated over larger sample size and longer duration to determine the long term effects of metabolic surgery.

The Effects of Laparoscopic Sleeve Gastrectomy (LSG) on Obesity-Related Type 2 Diabetes Mellitus: a Prospective Observational Study from a Single Center.

The objective of the study is to evaluate the effects of laparoscopic sleeve gastrectomy (LSG) on mid- to long-term regulation of blood glucose in patients with obesity and type 2 diabetes mellitus (T2DM) MATERIALS AND METHODS : In this prospective and observational single-center study, a total of 234 patients with obesity and a diagnosis of T2DM who underwent LSG between 2015 and 2020 were evaluated. The demographics and laboratory data, consisting of body mass index (BMI), glycosylated hemoglobin (HbA1c%), and fasting plasma glucose (FPG) and total weight loss (TWL%), were compared preoperative and postoperative at 12th and 18th months and annual follow-up for seven consecutive years. The mean age of 234 patients (female(n)/male(n):191/43) included in the study was 44.69±9.72 years, while the preoperative mean BMI, FPG, and HbA1c values were 47.9±6.82, 132.09±42.84 mg/dl, and 7.02±1.35% respectively. The mean rate of weight loss (TWL%), which was 34.7 in the 18 months, decreased to 23.15 in the 7th year. While the HbA1c % value was 7.02±1.35 in the preoperative, it was found 5.71 ± 0.75 (p<0.001) and 6.30 ± 1.77 (p<0.05) at the 18th month and 7th year after the operation, respectively. While the DM remission rate was 71.1% at the postoperative 18th month, it was 45.4% at the 7th year, despite the patients regaining weight in the follow-ups. Our study revealed that LSG resulted in high remission rates that continued for 7 years after the surgery, although sustained improvement or remission of diabetes despite some weight regain after the first 18 months.

Evaluation of Persistent Efficacy of Diabetes Remission and Decline of Cardiovascular Risk After Laparoscopic Sleeve Gastrectomy: a Preliminary 1-Year Study.

Laparoscopic sleeve gastrectomy (LSG) is a relative safe procedure in bariatric surgery. However, relatively few studies had been assessed its comprehensive efficacies. In the current study, the efficacies of LSG were comprehensively explored on glycemic control and cardiovascular disease (CVD) risk reduction. A total of 95 obese patients, who owned body mass index (BMI) of more than 35, were recruited. All of them primarily underwent LSG from 2014 to 2016. Type 2 diabetes mellitus (T2DM) remission was defined as levels of glycated hemoglobin (A1C) and fasting blood glucose (FBG) of less than 6.4% and 125mg/dL, respectively. The further efficacies of LSG on CVD and coronary heart disease (CHD) risks were explored by using original- and recalibrated Framingham 10-year CHD risk scores and the other 3 well-established CVD risk prediction models. Systolic blood pressure (SBP), serum FBG, A1C, triglyceride (TG), BMI, and body weight showed significantly declined and high-density lipoprotein-cholesterol (HDL) displayed twice higher than beginning level after LSG. The 71 of 95 patients with obesity were T2DM; 62 of them exhibited persistent DM remission until 1year after LSG. Cardiovascular age, general cardiovascular risk (GCVR), and atherosclerotic cardiovascular disease risk (ASCVD) also showed significant decrements after LSG. We also observed significant reductions in estimated CVD and CHD risks. LSG resulted in a persistent T2DM remission and corrected metabolic abnormalities. Subsequently, LSG also benefits declined risks of CVD and 10-year CHD developments. LSG may be helpful for primary CVD care in obese patients with BMI of more than 35.

Fibroblast Growth Factor 19 and Fibroblast Growth Factor 21 Regulation in Obese Diabetics, and Non-Alcoholic Fatty Liver Disease after Gastric Bypass.

Background: Gastric bypass (GB) is an effective treatment for those who are morbidly obese with coexisting type 2 diabetes mellitus (T2DM) or non-alcoholic fatty liver disease (NAFLD). Fibroblast growth factors (FGFs) are involved in the regulation of energy metabolism. Methods: We investigated the roles of FGF 19, FGF 21, and total bile acid among those with morbidly obese and T2DM undergoing GB. A total of 35 patients were enrolled. Plasma FGF 19, FGF 21, and total bile acid levels were measured before surgery (M0), 3 months (M3), and 12 months (M12) after surgery, while the hepatic steatosis index (HSI) was calculated before and after surgery. Results: Obese patients with T2DM after GB presented with increased serum FGF 19 levels (p = 0.024) and decreased total bile acid (p = 0.01) and FGF 21 levels (p = 0.005). DM complete remitters had a higher FGF 19 level at M3 (p = 0.004) compared with DM non-complete remitters. Fatty liver improvers tended to have lower FGF 21 (p = 0.05) compared with non-improvers at M12. Conclusion: Changes in FGF 19 and FGF 21 play differential roles in DM remission and NAFLD improvement for patients after GB. Early increases in serum FGF 19 levels may predict complete remission of T2DM, while a decline in serum FGF 21 levels may reflect the improvement of NAFLD after GB.

Evaluation of Metabolic Outcomes Following SADI-S: a Systematic Review and Meta-analysis.

Single anastomosis duodeno-ileal bypass with sleeve gastrectomy (SADI-S) offers a novel bariatric procedure. This systematic review and meta-analysis evaluates observational and comparative studies evaluating SADI-S, with meta-analysis comparing outcomes to other malabsorptive procedures (MPs). Systematic search of MEDLINE, Embase, Scopus, and Web of Science was conducted in March 2021. The study followed PRISMA guidelines. Studies evaluating SADI-S with n > 5 were included. Primary outcome was diabetes (DM) remission, and secondary outcomes included perioperative outcomes, comorbidity resolution, and weight loss. We reviewed 2285 studies with 16 included evaluating 3319 patients and 1704 (51.3%) undergoing SADI-S. SADI-S patients had increased BMI (49.6kg/m2 vs 48.8kg/m2) and weight (139.7kg vs 137.1kg), were more likely to have DM (46.3% vs 42.1%), and dyslipidemia (36.6% SADI-S vs 32.7%). SADI-S had a shorter operative duration than MPs (MD - 36.74, p < 0.001), 0.85-day shorter post-operative stay (p < 0.001), and trended towards fewer complications (OR 0.69, p = 0.06). Rate of reoperation (OR 0.83, p = 0.59) was similar and DM remission was similar (OR 0.07, p = 0.1). Subgroup analysis suggested greater DM remission than Roux-en-Y gastric bypass (OR 4.42, p = 0.04). SADI-S had fewer malabsorptive complications, though follow-up was shorter. Weight loss was 37.3% compared to 35.6% total weight loss after SADI-S and MPs, respectively. SADI-S demonstrates improved metabolic and weight loss outcomes with lower perioperative risks. SADI-S represents a promising bariatric procedure but long-term outcomes are needed to guide future uptake.

Bariatric Surgery: Late Outcomes in Patients Who Reduced Comorbidities at Early Follow-Up.

Backgroundand Objectives: In severe obesity, a relevant weight loss can promote the reduction of comorbidities, such as systemic arterial hypertension (SAH), dyslipidemia, and diabetes mellitus (DM2). Bariatric surgery (BS) has been an essential resource in the therapy of this disease with a short-term reduction of cardiometabolic risk (CR). This study aimed to evaluate the reduction of factors associated with the CR in patients undergoing BS at a 5-year follow-up. Materials and Methods: This is a longitudinal, retrospective study carried out with patients undergoing BS by the Brazilian Public Healthcare System (PHS). Anthropometric and clinical parameters related to the CR (DM2, dyslipidemia, and SAH), quantified by the Assessment of Obesity-Related Comorbidities (AORC) score, were evaluated at the following moments: admission and preoperative and postoperative returns (3 months, 6 months, 1 to 5 years). Results: The sample had a mean age of 44.69 ± 9.49 years and were predominantly in the age group 20–29 years (34.80%) and women (72.46%). At admission to the service, 42.3% had DM2, 50.7% dyslipidemia, and 78.9% SAH. Regarding BS, the gastric bypass technique was used in 92.86% of the sample, and the waiting time for the procedure was 28.3 ± 24.4 months. In the pre- and postoperative period of 3 months, there was a significant reduction in the frequency of DM2 (p < 0.003), dyslipidemia (p < 0.000), and SAH (p < 0.000). However, at postoperative follow-up from 6 months to 5 years, there was no significant reduction in the comorbidities studied. After five years, 35.7% had total remission of DM2 and 2.9% partial remission of DM2, 44.2% had control and remission of dyslipidemia, and 19.6% of SAH (AORC score ≤ 2 for the comorbidities). Conclusion: BS promoted a reduction of the CR in the first three months after BS in severely obese PHS users.

Factors associated with resolution of type-2 diabetes mellitus after sleeve gastrectomy in obese adults

Many bariatric procedures are more effective for improving type-2 diabetes mellitus (T2DM) than conventional pharmacotherapy. The current research evaluated factors linked to complete and partial remission or improvement of T2DM after laparoscopic sleeve gastrectomy (LSG). The current prospective study included all diabetic patients who were submitted LSG between January 2015 and June 2018 and completed a 2-year follow-up period. Patients were assessed at baseline and 2 years after LSG. This work comprised of 226 diabetic cases. Two years after LSG, 86 patients (38.1%) achieved complete remission of DM, and 24 (10.6%) reached partial remission. Only 14 patients (6.2%) showed no change in their diabetic status. On univariate analysis, age ≤ 45 years, duration of diabetes ≤ 5 years, use of a single oral antidiabetic, HbA1c ≤ 6.5%, HOMA-IR ≤ 4.6, C-peptide > 2.72 ng/mL, and BMI ≤ 40 kg/m2 predicted complete remission. The independent predictors of complete remission were age ≤ 45 years, duration of diabetes ≤ 5 years, use of a single oral antidiabetic, HOMA-IR ≤ 4.6, and C-peptide > 2.72 ng/mL. A combined marker of young age, short duration of DM, and low HOMA-IR predicted complete remission with sensitivity 93% and specificity 82%. Independent predictors of complete remission of T2DM after LSG were younger age, shorter duration, single oral antidiabetic, lower HOMA-IR, and higher C-peptide.

Impact of Metabolic Surgery on Type-2 Diabetes Remission.

Diabetes Mellitus is characterized by numerous metabolic disorders, which have in common the serum elevation of glucose, caused for a pancreatic malfunction in insulin secretion and / or its action. It is a non-communicable disease, considered major public health problems and generalized growth worldwide, being a chronic disease, which can generate a high treatment cost. Metabolic surgery is a safe treatment, regulated by the Federal Council of Medicine and useful in treating people with BMI over 30 years of age, who are unable to control pathologies associated with obesity, primarily type 2 diabetes. The general objective of this study is to understand through a literature review the main impacts of metabolic surgery about the remission of DM 2. This present study it is an exploratory and descriptive study carried out through a literature review. Data were collected through research in virtual health databases, at the Virtual Health Library - VHL, Latin American and Caribbean Health Sciences Information System, LILACS, National Library of Medicine - MEDLINE, Scielo, USP database, PUBMED theses and books. Metabolic surgery proof be a good and effective treatment for having and maintaining good weight loss, as well as a significant clinical and metabolic improvement that extends beyond weight loss. Metabolic surgery is a satisfactory way of achieving long-term weight reduction in obese individuals, increasing survival for these patients. Obese patients with DM2 have a long-term remission of DM2 after bariatric / metabolic surgery. Therefore, it concludes that such procedure is effective in the treatment of the disease and other diseases associated with obesity.

Weight loss dynamics following laparoscopic Roux-en-Y gastric bypass. An analysis of 10-year follow-up data.

Laparoscopic Roux-en-Y gastric bypass (LRYGB) still remains the gold-standard bariatric procedure. Short-term weight loss and improvement of type 2 diabetes mellitus (DM2) after LRYGB are well-documented. Little data are available on long-term weight loss and continued remission of DM2 in these patients. This study reports on weight loss and remission of DM2 in 576 consecutive patients who underwent primary LRYGB between August 2001 and August 2009 with at least 10-year follow up. All patients were treated at a single institution by a single surgeon. All data were collected and entered into the database prospectively. A total of 576 patients were included in the study. Patients' mean age was 38.2 ± 10.9years and females represented 88.2% of patients. Patients' ethnicity was diverse, including African Americans (44.4%), Caucasians (34.0%), Hispanics (18.1%), and 3.5% from other backgrounds. On average, there were 6.9 ± 2.7 comorbidities per patient and DM2 was initially present in 150/576 patients (26.0%). Mean preoperative weight and BMI were 132.4 ± 22.0kg and 48.3 ± 6.7kg/m2, respectively. Ten-year follow-up reporting rate was 145/576 (25.2%). Maximum weight loss occurred at 18months (mean weight 83.4 ± 16.5kg, mean BMI 30.5 ± kg/m2). At 10years, mean weight was maintained at 94.8 ± 20.5kg and mean BMI was 34.3 ± 6.8kg/m2. The average weight regain between one and ten years was 8.27kg. Among patients with preoperative DM2, continued remission of DM2 at 10years occurred in 19/32 (59.4%) patients. LRYGB provides durable long-term weight loss, as well as successful remission of DM2 at 10years. More long-term follow-up studies evaluating weight loss and comorbidities extending beyond the initial 10-year period are needed. Such studies are essential for projecting late outcomes of LRYGB, particularly in younger patients with life expectancy exceeding several decades.

Correlation of PMN elastase and PMN elastase-to-neutrophil ratio with disease activity in patients with myositis

BackgroundPolymorphonuclear (PMN) elastase plays an important role in a variety of inflammatory disorders. Our aim was to analyse PMN elastase in idiopathic inflammatory myopathies (IIMs) and its association with disease activity.MethodsPMN elastase levels were measured using enzyme-linked immunosorbent assay in serum samples obtained from 74 patients with myositis (58 with dermatomyositis [DM] and 16 with polymyositis [PM]) and 22 healthy controls. Receiver operating characteristic (ROC) curve analysis was performed to evaluate the discriminant capacity of PMN elastase level and PMN elastase-to-neutrophil ratio (ENR) in patients with active and remission myositis. The association of serum PMN elastase level and ENR with disease variables was evaluated in patients with IIMs. The disease specificity of PMN elastase level and ENR was further examined in 60 patients with other systemic autoimmune diseases.ResultsPMN elastase level and ENR were significantly higher in patients with active IIMs, DM, and PM than in patients with remission. ROC curve analysis revealed that PMN elastase level and ENR both outperformed creatine kinase (CK), the currently used laboratory marker, and strongly discriminated patients with active disease and those with remission of IIMs, DM, and PM (area under the ROC curve [AUC] 0.9, 0.9, and 0.88 for PMN elastase; AUC 0.96, 0.96, and 1.0 for ENR; AUC 0.72, 0.70, and 0.80 for CK, respectively). PMN elastase level and ENR were positively correlated with myositis disease activity assessment, CK, lactate dehydrogenase, aspartate aminotransferase, alanine aminotransferase, C-reactive protein, and erythrocyte sedimentation rate. PMN elastase level and ENR were higher in the anti-PM-Scl positive myositis group than those in the anti-PM-Scl negative myositis group. Nevertheless, PMN elastase was not a specific disease marker for IIMs when compared with other autoimmune diseases.ConclusionsPMN elastase, particularly ENR, were significantly correlated with disease activity and could serve as useful biochemical markers for evaluating the disease activity of patients with IIMs. Thus, they are potentially helpful in monitoring disease progression and guiding treatment.

Dieta low carb como estratégia de manejo na remissão do diabetes mellitus insulinorresistente: síntese de evidências

Introdução: O DM tipo II está associado à deficiência no funcionamento de determinados mecanismos responsáveis pela regulação da sensibilidade tecidual à ação da insulina, em concomitância à secreção deficiente do hormônio pelas células beta pancreáticas. As dietas LC restringem os carboidratos diários para algo entre 20 e 50g, mostrando associação com uma considerável perda de peso. Todavia, os efeitos da dieta LC no controle do DM II são bastante controversos. Objetivo: Realizar uma revisão da literatura englobando ensaios clínicos que comprovadamente testaram os efeitos da dieta LC na remissão do DM II. Método: Para seleção dos trabalhos foi utilizada a seguinte estratégia de busca: (low-carb OR "low carb" OR “low carbohydrate” OR low-carbohydrate OR ketogenic OR Atkins) AND (diabetes OR diabetics) AND (type-2 OR "type 2" OR type-II OR "type II" OR "insulinresistant") AND "clinical trial", na base de dados PUBMED/MEDLINE. Resultados: Foram revisados 12 artigos que preencheram os critérios de inclusão. Síntese de Evidências: A dieta LC melhora o equilíbrio glicêmico, devendo ser considerada em pacientes portadores de DM tipo II e que necessitam de suporte nutricional. A referida dieta ainda reduz a gordura visceral, melhora a sensibilidade à insulina e aumenta os níveis de HDL. A estabilidade da glicemia diurna e do perfil lipídico podem ser mantidos com a dieta LC, sem efeitos adversos renais, e sem a necessidade de medicamentos hipoglicemiantes. A dieta é bem tolerada e se mostra bastante segura, mesmo quando prescrita em longo prazo.

A405 - Remission of type 2 diabetes one year after bariatric surgery among Asian population

Background: Bariatric procedures are effective treatment for type 2 DM with either improvement of glycaemic control or remission of DM. The aim of this study is to look at remission of DM 1 year after Bariatric procedures (Laparoscopic Roux-En-Y Gastric bypass LRYGB and Laparoscopic sleeve gastrectomy LSG) among Asian population.

Metabolic Surgery Counseling, Diabetes Remission, and A1C Control in Patients with Diabetes and Obesity

Metabolic surgery (MS) can lower A1c and achieve DM remission. Counseling by a healthcare provider is an important initial step in considering MS. We hypothesized that MS counseling results in a significant increase in DM remission and A1c improvement. We retrospectively studied 3,676 adults aged 18-65 with T2DM, BMI ≥35 kg/m2, and A1c ≥6.5% followed at two academic medical centers between 2000-2015, using a software tool to identify MS counseling in EMR notes. Counseling and outcomes were assessed over one and three years after study entry, respectively. Study patients’ mean age was 50.8 years and mean baseline A1c was 8.2%. Over one year after study entry, 20.2% of patients had MS counseling. In univariate analyses, patients who received MS counseling had a higher rate of DM remission (A1c&amp;lt;6.5% and no DM medications besides metformin) and were more likely to have achieved A1c control (&amp;lt;7.0%) vs. those who did not (Figure). In multivariable analyses adjusted for patient demographics and comorbidities, MS counseling was associated with an OR of 1.43 (95% CI 1.11-1.84; p=.0051) for achieving DM remission and an OR of 1.44 (95% CI 1.15-1.81; p=.0015) for achieving A1c control. In this large study of patients with T2DM and obesity, MS counseling was associated with significantly greater rates of DM remission and A1c control. These findings suggest MS counseling is an important step in the treatment of DM and obesity. Disclosure L. Chang: None. S. Malmasi: None. N. Hosomura: None. H. Zhang: None. C.J. Brown: None. V.J.

Five-Year Glycemic and Metabolic Outcomes after Bariatric Surgery in an Asian Population with Type 2 Diabetes

Background: Metabolic-bariatric surgery (MBS) leads to durable weight loss and significant metabolic improvement in type 2 diabetes mellitus (T2DM) patients with obesity. However, data on durability of control is often lacking in Asia. Aim: We report 5-year glycemic and metabolic outcomes in a T2DM cohort who had MBS from 2008-2012 at a tertiary center in Singapore. Methodology: Patient demographics and biochemical parameters were retrieved from a web-based data repository. DM remission was defined as HbA1c ≤6% without DM medications. Results: There were 59 patients with a mean age of 43.0±9.5 years and 37.3% were males (Table 1). Most (76.3%) had gastric bypass while 23.7% had sleeve gastrectomy. Baseline mean weight and BMI were 114.4±27.4 kg and 42.5±10.5 kg/m2 respectively. Mean weight loss of 26% was achieved at 1 year and sustained over 5 years. Mean HbA1c decreased from 8.3% to 5.8% and 6.3% at 1 and 5 years respectively, with use of fewer DM, anti-hypertensive and lipid-lowering medications. At 5 years, 18 of 43 (41.9%) patients achieved sustained remission of diabetes with 6 (14.0%) having relapse of DM after initial remission at 1 year. Conclusion: MBS is effective therapy for obesity and DM with durable glycemic and metabolic control associated with lower medication use over 5 years in this Asian population.Table 1.

Metabolic Surgery for the Treatment of Diabetes Mellitus Positioning of Leading Medical Associations in Mexico

IntroductionMetabolic surgery (MS) can be a useful therapeutic strategy in patients with type 2 diabetes (DM2) and obesity.ObjectiveTo define the place of MS within DM2 treatment in Mexico.MethodsA committee of experts consisting of internists and surgeons representing the leading Mexican associations involved in the field was created. Each one responded to a specific question regarding mechanisms involved in controlling DM2, surgical procedures, and the indications and contraindications for MS. This document was prepared based on the presentation and discussion of such answers.ResultsObesity through insulin resistance, incretins, bile salts, and intestinal microbiota plays a determining role in the appearance of DM2. MS improves glucose homeostasis by reducing weight and intake, increasing incretins, and modifying bile salts and microbiota. MS leads to remission of DM2 and reduces cardiovascular risk factors in well-selected cases. We recommend MS as a therapeutic option in DM2 and grade III obesity regardless of metabolic control and grade II and grade I obesity with poor glycemic control. MS could be considered an option in grade II obesity with good metabolic control in the presence of associated comorbidities. Gastric bypass presents the most favorable risk-benefit profile.ConclusionsCurrent evidence endorses the inclusion of MS in the algorithm for treatment of DM2 and obesity. The therapeutic approach must be multidisciplinary at experienced centers.

The Predictive Factors for Diabetic Remission in Chinese Patients with BMI > 30kg/m2 and BMI < 30kg/m2 Are Different.

Roux-en-Y gastric bypass has been proven to be beneficial for patients with obesity and type 2 diabetes mellitus (T2DM). In less-obese patient (BMI 30-35kg/m2), surgical treatment is indicated when medication fails to control the T2DM. Asian develops diabetes at a lower BMI. For lower-BMI patients, the rate of diabetes amelioration varies significantly with patients of higher BMI after surgical treatment. The factors that contribute to the post-operative diabetes response rate in lower-BMI patients have not been elucidated. Between 2010 and 2014, a total of 144 patients who underwent gastric bypass for the treatment of T2DM were included for study. Patients were divided into two groups for subgroup analysis, namely BMI > 30kg/m2 and BMI < 30kg/m2. Factors affecting the remission rate were examined. Of the studied patients, the DM remission rate for the high-BMI group (BMI > 30kg/m2) was 80% (n = 90) whereas for the lower BMI (BMI < 30kg/m2) was 50% (n = 54), p < 0.001. For high-BMI group, low HbA1c and high fasting C-peptide are predictive factors whereas for lower-BMI group, along with elevated C-peptide level, disease duration is the positive predictive factor for DM remission. Patients with BMI > 30kg/m2 and those with BMI < 30kg/m2 have distinct remission predicting factors. Low HbA1c is a predictor of remission in low-high-BMI patients while duration of diabetes is for high-low-BMI patients. C-peptide is a predictor of remission in both groups. Further large-scale studies are required to define the predictors of diabetes remission after gastric bypass in low- and high-BMI patients.

Association of 5-HT2C (rs3813929) and UCP3 (rs1800849) gene polymorphisms with type 2 diabetes in obese women candidates for bariatric surgery.

Obesity can cause systemic arterial hypertension (SAH) and type 2 diabetes mellitus (DM2) factor that is also influenced by genetic variability. The present study aims to investigate the association between gene polymorphisms related with obesity on the prevalence of SAH and DM2 in the preoperative period and 1 year after Roux-en-Y gastric bypass surgery. In total, 351 obese women in a Brazilian cohort completed the study. The clinical diagnosis of SAH and DM2 was monitored from medical records. Twelve gene polymorphisms (rs26802; rs572169; rs7799039; rs1137101; rs3813929; rs659366; rs660339; rs1800849; rs7498665; rs35874116; rs9701796; and rs9939609) were determined using real-time polymerase chain reaction and TaqMan assay. In the preoperative period, prevalence of SAH and DM2 was 57% and 22%, respectively. One year postoperatively, 86.8% subjects had remission of DM2 and 99.5% had control of SAH. Subjects with T allele from the serotonin receptor gene (5-HT2C, rs3813929) had five times greater chance of DM2, and the CC genotype from uncoupling protein 3 gene (UCP3, rs1800849) had three times greater chance in the preoperative period. These findings indicate that polymorphisms rs3813929 and rs1800849 from 5-HT2C and UCP3 genes were related to DM2 prevalence among the Brazilian obese women candidates for bariatric surgery.

Type 2 Diabetes Mellitus remission eighteen months after Roux-en-Y gastric bypass.

to evaluate the effectiveness of Roux-en-Y gastric bypass in improving the glycemic profile of obese patients with type 2 Diabetes Mellitus (DM2) after 18 months of follow-up. four hundred sixty-eight pacients with DM2 and BMI ≥35 were submitted to Roux-en-Y gastric bypass, from 1998 to 2010. All patients were submitted to glycemic control analysis in the 3rd, 6th, 9th, 12th and 18th postoperative months. We considered: type 2 diabetic patients, the ones with fasting glucose ≥126mg/dl and HbA1C ≥6.5 in two dosages; high risk patients for diabetes, those who presented fasting glucose ≥ 100 to 125 mg/dl and HbA1C between 5.7%-6.4%; and normal patients, those presenting glucose <100mg/dl and HbA1C <5.7%. Such diagnostic criteria were based on the official position of Sociedade Brasileira de Diabetes, published in July, 2011. The remission of DM2 was seen in 410 (87.6%) out of 468 patients 18 months after the surgery, that being a meaningful difference, with p<0.001. Fourty-eight (10.3%) patients sustained criteria for the disease and ten (2.1%) continued at high risk for DM2. Roux-en-Y gastric bypass was effective in the promotion and maintaince of long-term glycemic control. There are evidences showing that the remission of DM2 is not only related to weight loss and that other enteroinsular axis mechanisms must be involved. avaliar a eficácia da gastroplastia com derivação em Y-de-Roux, em pacientes obesos e portadores de Diabetes Mellitus tipo 2 (DM2), na melhoria do perfil glicêmico após 18 meses de seguimento. foram submetidos à derivação gástrica em Y-de-Roux 468 pacientes com IMC ≥35 e portadores de DM2, no período de 1998 a 2010. Todos os pacientes tiveram a análise do controle glicêmico realizadas no terceiro, sexto, nono, 12o e 18o meses de pós-operatório. Os critérios diagnósticos de diabetes foram baseados no Posicionamento Oficial da Sociedade Brasileira de Diabetes, publicado em julho de 2011. observou-se a remissão do DM2 em 410 pacientes (87,6%) após 18 meses da cirurgia, sendo essa diferença significativa com p-valor <0,001. A doença se manteve inalterada em 48 pacientes (10,3%), e dez pacientes (2,1%) permaneceram com o risco aumentado para DM2. a gastroplastia com derivação em Y-de-Roux foi efetiva na promoção e manutenção do controle glicêmico em longo prazo.
