Navigating the Predictive Landscape: DiaRem's Role in Unveiling Outcomes for Diabetes Remission following ESG.

Rising obesity and type 2 diabetes mellitus (T2DM) rates can be mitigated by various strategies, with a 10% total body weight loss (TBWL) threshold often required for T2DM remission. T2DM remission rates after bariatric surgery like Roux-en-Y gastric bypass (RYGB) are well established; endoscopic sleeve gastroplasty (ESG) is a less invasive option that averages 15% TBWL and allows for T2DM remission. This study explores the DiaRem (Diabetes Remission post-RYGB) score's ability to predict T2DM remission 1-year post-ESG. We conducted a retrospective cohort study on 39 individuals with T2DM who underwent ESG. Age, utilization of diabetes medications, insulin administration, and hemoglobin A1c levels were used to calculate the DiaRem score. The area under the receiver operating characteristic curve (AUC) was employed to evaluate the discriminative ability of DiaRem in distinguishing diabetes remission. Among the 39 patients with a median hemoglobin A1c of 6.7, 12.8% required insulin, and 43.6% used diabetes medication. At 1-year post-ESG, 69.2% of patients experienced diabetes remission with a median %TWBL of 12.7. The DiaRem score's ability to detect diabetes resolution for ESG patients had a sensitivity of 100% and a specificity of 58.3%, at the optimal cutoff value of 10. The AUC was 0.779 (95% CI 0.546-0.959). Our study demonstrated the DiaRem score's predictive value for T2DM remission post-ESG, highlighting its utility in clinical decision-making for ESG-related outcomes. Further investigation is needed to identify alternative indicators that may enhance predictive accuracy, thus refining personalized decision-making for this patient group.

Remission of Type II Diabetes Mellitus after Duodenal Switch: the Contribution of Common Channel Length

IntroductionThe role of the common channel length in duodenal switch (DS) on remission of type II diabetes mellitus (DM), when stratifying patients based on diabetes severity, is not well understood.MethodsWe retrospectively reviewed 341 consecutive patients with DM undergoing DS with one of three different common channel (CC) lengths (100 cm, 150 cm, and 200 cm), each with a fixed 300 cm alimentary limb (AL). Patients were stratified by insulin dependence (IDDM) versus non-insulin dependent diabetes (NIDDM). Data was collected at one year and at the last available follow-up.ResultsThe NIDDM group had a similar average HbA1c at last follow-up for each of the CC lengths. However, the IDDM group had lower average HbA1c with shorter CC lengths (100 cm = 5.4%, 150 cm = 6%, 200 cm = 6.4%, p < 0.05). Shorter CC lengths resulted in a greater proportion of patients achieving remission in the IDDM group (66%, 50%, 32% in the 100 cm, 150 cm, and 200 cm CC, respectively, p < 0.01). Improvements in HbA1c were independent of weight loss and average DiaRem scores were similar between CC lengths. Rates of nutritional deficiencies were higher in shorter common channel lengths. Revision for malnutrition was similar between common channel lengths (100 cm group: 3.7%; 150 cm group: 1.8%; 200 cm group: 0%, p = NS).ConclusionsWhen the AL is fixed, shortening CC lengths results in improved glycemic control and remission of DM in patients with the need for insulin preoperatively. Milder forms of DM are treated well with any of the CC lengths.Graphical

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.

Comparison of scoring systems for predicting remission of type 2 diabetes in sleeve gastrectomy patients.

Introduction: This study aims to compare the predictive capacity of ABCD, DiaRem2, Ad-DiaRem, and DiaBetter scoring systems for type 2 diabetes mellitus (T2DM) remission in Turkish adult morbidly obese patients who underwent SG. Methods: This retrospective cohort study included 80 patients who underwent sleeve gastrectomy (SG) operation who were diagnosed with T2DM preoperatively, and had at least one-year follow-up after surgery. Because bariatric surgery is performed on patients with class III obesity (BMI ≥ 40 kg/m2) or class II obesity (BMI ≥ 35 kg/m2) with obesity releated comorbid conditions in our hospital, our study cohort consisted of these patients. Results: The diagnostic performance of the DiaBetter, DiaRem2, Ad-DiaRem and ABCD for identifying diabetes remission, assessed by the AUC was 0.882 (95% CI, 0.807-0.958, p < 0.001), 0.862 (95% CI, 0.779-0.945, p < 0.001), 0.849 (95% CI, 0.766-0.932, p < 0.001) and 0.726 (95% CI, 0.601-0.851, p = 0.002), respectively. The AUCs of the Ad-Diarem, DiaBetter and DiaRem2 were statistically higher than AUC of the ABCD (all p-value < 0.001). Besides, there was no statistically significant difference in AUCs of the Ad-Diarem, DiaBetter and DiaRem scores (all p-value > 0.05). Conclusion: Ad-Dairem, DiaBetter and DaiRem scoring systems were found to provide a successful prediction for diabetes remission in sleeve gastrectomy patients. It was observed that the predictive power of the ABCD scoring system was lower than the other systems. We think that the use of scoring systems for diabetes remission, which have a simple use, will become widespread.

IDF21-0401 How accurate are DiaRem, Ad-DiaRem or DiaBetter scores in predicting diabetes remission 10 years after gastric bypass?

Background: The vast majority of patients submitted to Roux-en-Y Gastric Bypass (RYGB) experience substantial and sustained weight loss, as well as significant improvement or resolution of obesity-associated comorbidities, and most particularly Type 2 Diabetes (T2D). However, up to 20% of operated patients fail to benefit from surgery in terms of weight loss or diabetes control. A percentage that tends to increase along the post-operative timespan. The accuracy of DiaRem, Ad-DiaRem and DiaBetter scores, based on pre-operative parameters, for predicting short-term T2D remission after bariatric surgery was previously demonstrated. None of these scores were yet assessed for the possibility of predicting long-term T2D remission. Aim: This study aim was to evaluate DiaRem, Ad-DiaRem and DiaBetter accuracy at predicting T2D remission more than 10 years after RYGB surgery. Method: Patients with obesity and T2D (n=72) submitted to RYGB for the primary treatment of obesity with 10 or more years of follow-up were included in this study. All patients had surgery performed by the same team at a single hospital center. From those patients pre-operative anthropometric and clinical data was retrieved to calculate DiaRem, Ad-DiaRem and DiaBetter scores and a clinical evaluation was conducted to assess diabetes status. Scores accuracy in predicting long-term T2D remission was estimated by calculating the receiver operating characteristic (ROC) area under the curve (AUC). Results: From all patients with pre-operative T2D (n=72), 39 subjects (53.4%) achieved and maintained T2D remission 10 or more years after RYGB. The DiaRem score (AUC=0.826) depicted the highest discriminative power to predict long-term T2D remission than Ad-DiaRem (AUC=0.760) and DiaBetter (AUC=0.778). Pre-operative T2D diagnosis duration does not seem to be a good predictor of long-term T2D remission, in contrast to what is reported for short-term T2D remission prediction. Discussion: Our study demonstrated that DiaRem has a higher accuracy than Ad-DiaRem and DiaBetter scores to predict long-term T2D remission after RYGB surgery. Nevertheless, these scores accuracy to predict long-term T2D remission is lower than reported for short-term T2D remission prediction by previous studies. Thus, a better scoring system optimized for predicting long-term T2D after bariatric surgery is still needed.

Sensitivity of DiaRem Scoring System in Predicting Type Two Diabetes Mellitus Resolution After Bariatric Surgery in Qassim Region.

Introduction: Type two diabetes mellitus (T2DM) remission has been observed as an additional benefit of bariatric surgery for morbidly obese diabetic patients. There are many scoring systems for identifying factors that predict diabetes remission; however, there is as yet no universally applicable scoring system.Aim: This study aims to test the sensitivity of the DiaRem scoring system for predicting the resolution of T2DM in morbidly obese patients who underwent bariatric surgery at King Fahad Specialist Hospital in Buraydah, Saudi Arabia.Methods: This was a non-randomized controlled trial conducted at King Fahd Specialist Hospital in Buraydah, Saudi Arabia. Visiting patients at first screening were enrolled based on eligibility criteria. Data were collected according to the given parameters such as gender, age, body mass index (BMI), duration of diabetes mellitus (DM), medications (insulin, oral antihyperglycemic agents, number of tablets if used, or no medications use), presence of comorbidities, such as hypertension and dyslipidemia, HbA1c level (before surgery and at third, sixth, and 12th months after surgery), and fasting blood glucose (FBG) level (before and after surgery).Results: A total of 96 diabetic patients were enrolled (35 males vs 61 females) with a mean age of 46.5 years. Laparoscopic sleeve gastrectomy was the most commonly performed surgery. The most common associated comorbidities were hypertension (50%) and hypothyroidism (14.6%). Results of the DiaRem scoring system showed 0-2 points in 15.6% patients, 3-7 points in 39.6% patients, 8-12 in 26% patients, 13-17 in 9.4% patients, and 18-22 in 9.4% patients. The lowest DiaRem score was associated with a higher value of BMI, shorter DM duration, and lower mean values of HbA1c and FBG post-surgery.Conclusion: Consistent with the literature, our results indicated that those with an increased BMI, shorter duration of DM, and lower values of HbA1c post-FBG had a greater chance of diabetes remission postoperatively.

Remission of Type II Diabetes Mellitus 1-Year Postoperative Following One Anastomosis Gastric Bypass in Correlation with ABCD, DiaRem, and DRS Scores.

Diabetes mellitus (DM) is a debilitating chronic illness. Roux en-Y gastric bypass (RYGB) and one anastomosis gastric bypass (OAGB) present a potential solution to type II DM. Several scoring systems predict DM remission as ABCD score, DiaRem score, and diabetes remission score (DRS). This was a retrospective study that included 138 patients with DM and underwent OAGB. BMI, HbA1C, insulin, and oral hypoglycemics need were recorded pre- and postoperatively with calculation of ABCD, DiaRem, and DRS scores. Effects of OAGB on DM were observed and correlated with the scoring systems to detect their sensitivity and specificity. Age, preoperative, and postoperative BMI were 47.38 ± 7.632, 45.096 ± 4.465, and 31.173 ± 3.799 respectively. The preoperative and stimulated C-peptides were 3.357 ± 0.995 and 4.158 ± 0.897ng/ml respectively. The preoperative and postoperative HbA1C were 7.396 ± 0.743% and 6.564 ± 0.621% respectively. Patients with complete remission were 32 patients (23.2%) and with partial remission were 46 patients (33.3%) adding to 56.5% considered in remission. There was significant decrease of BMI, HbA1C, insulin, and oral hypoglycemic use postoperatively. Receiver operator characteristics (ROC) curve showed that ABCD, DiaRem, and DRS scores had AUC of 0.853 with cut-off > 5, 0.921 with cut-off ≤ 8, and 0.805 with cut-off ≤ 8 respectively. The DiaRem score had the highest AUC followed by ABCD score then DRS score. OAGB significantly reduced BMI and HbA1C values 1year postoperatively with 56.5% DM remission. DiaRem score had more remission predictive value following OAGB than ABCD and DRS scores especially when ≤ 8 with 90.6% sensitivity and 83% specificity.

Metabolites and diabetes remission after weight loss

There is marked heterogeneity in the response to weight loss interventions with regards to weight loss amount and metabolic improvement. We sought to identify biomarkers predictive of type 2 diabetes remission and amount of weight loss in individuals with severe obesity enrolled in the Longitudinal Assessment of Bariatric Surgery (LABS) and the Look AHEAD (Action for Health in Diabetes) studies. Targeted mass spectrometry-based profiling of 135 metabolites was performed in pre-intervention blood samples using a nested design for diabetes remission over five years (n = 93 LABS, n = 80 Look AHEAD; n = 87 remitters), and for extremes of weight loss at five years (n = 151 LABS; n = 75 with high weight loss). Principal components analysis (PCA) was used for dimensionality reduction, with PCA-derived metabolite factors tested for association with both diabetes remission and weight loss. Metabolic markers were tested for incremental improvement to clinical models, including the DiaRem score. Two metabolite factors were associated with diabetes remission: one primarily composed of branched chain amino acids (BCAA) and tyrosine (odds ratio (95% confidence interval) [OR (95% CI)] = 1.4 [1.0–1.9], p = 0.045), and one with betaine and choline (OR [95% CI] = 0.7 [0.5–0.9], p = 0.02).These results were not significant after adjustment for multiple tests. Inclusion of these two factors in clinical models yielded modest improvements in model fit and performance: in a constructed clinical model, the C-statistic improved from 0.87 to 0.90 (p = 0.02), while the net reclassification index showed improvement in prediction compared to the DiaRem score (NRI = 0.26, p = 0.0013). No metabolite factors associated with weight loss at five years. Baseline levels of metabolites in the BCAA and trimethylamine-N-oxide (TMAO)-microbiome-related pathways are independently and incrementally associated with sustained diabetes remission after weight loss interventions in individuals with severe obesity. These metabolites could serve as clinically useful biomarkers to identify individuals who will benefit the most from weight loss interventions.

C Peptide Fails to Improve the Utility of the DiaRem Algorithm in Predicting Remission of Type II Diabetes After Bariatric Surgery.

We evaluated the utility of C peptide as an addition to the DiaRem score for predicting type 2 diabetes (T2D) remission 1 year after bariatric surgery in 175 patients. DiaRem score was significantly correlated with C peptide (r = - .43; p < .001). Both DiaRem and C peptide were significant predictors of remission of T2D (OR (95% CI) = .81 (.75-.86); p < 0001 and OR (95% CI) = 1.35 (1.15-1.60); p < .001, respectively). ROC analysis indicated that DiaRem was a significantly stronger predictor than C peptide (p < .001). Hierarchical regression indicated that C peptide failed to significantly improve the prediction of diabetes remission after accounting for DiaRem (OR (95% CI) = 1.079 (.87-1.26); p = .406). This study does not support the inclusion of C peptide in the DiaRem algorithm.

Role of DiaRem Score in Preoperative Prediction of Type 2 Diabetes Mellitus Remission After Laparoscopic Roux-en-Y Gastric Bypass: Indian Perspective.

Roux-en-Y gastric bypass (RYGB) has emerged as the most effective treatment in reversing insulin resistance in patients with type 2 diabetes mellitus (T2DM). A number of models and statistical tools have been proposed to predict patients likely to experience diabetes remission post-RYGB. The purpose of our study was to evaluate the preoperative accuracy of DiaRem score in predicting T2DM remission at 1year of follow-up in a retrospective analysis of diabetic morbidly obese patients who underwent RYGB. One hundred and forty-three patients underwent RYGB between January 2018 and December 2018. We conducted a retrospective analysis in 55 patients (38.46%) with T2DM with 1year of follow-up. DiaRem score was calculated, and patients were stratified in five groups. At a 1-year follow-up, we found a higher proportion of patients with T2DM remission in the lower score group compared to a lower proportion of patients with remission in the higher score group. We derived a DiaRem cut-off score of 6.5 that had high sensitivity and specificity to predict T2DM remission preoperatively. We found a significant decrease in BMI and HbA1C values post-operatively at 1year following RYGB. DiaRem score is an easy to determine score based on basic clinical parameters that could identify patients with T2DM who would achieve maximal benefit in terms of remission after bariatric surgery. The development of a suitable scoring tool would be clinically useful as it would enable clinicians to better triage patients for RYGB.

Type 2 Diabetes Remission 5\xa0Years After Laparoscopic Sleeve Gastrectomy: Multicenter Cohort Study

PurposeBariatric surgery is no longer considered only as a weight loss surgery but also a way of treating obesity-related comorbidities such as type 2 diabetes mellitus (T2DM). Short-term T2DM remissions in patients undergoing laparoscopic sleeve gastrectomy (LSG) have been shown, but there are very few reports on the mid-term results. We aimed to assess the remission rate of T2DM in obese patients after LSG throughout 5-year follow-up.Materials and MethodologyWe performed a retrospective multicenter cohort analysis of 240 patients who underwent LSG. We assessed the remission rate of T2DM 1 year and 5 years after surgery.ResultsForty-six percent of patients achieved T2DM remission 5 years after LSG. The remission group had better weight loss results (median% of total weight loss 5 years after: 30.1% (22.9–37.0) vs 23.0% (13.7–30.2), p < 0.001) and were significantly younger than the no remission group (43 (38–52) vs 52 (44–58) years, p < 0.001). Duration of T2DM was significantly shorter (2 (1–5) vs 5 (3–10) years, p < 0.001) with less insulin requirement and less diabetes-related complications (7.2% vs 19.8%, p < 0.001) and significantly lower median DiaRem score (4.0 (IQR 2.0–6.0) vs 12.0 (IQR 5.0–16.0), p < 0.001). Preoperative body mass index (BMI) had no effect on remission.ConclusionsOur study suggests that diabetes remission after laparoscopic sleeve gastrectomy occurs frequently, and in the 5-year follow-up, it may remain at the level of 46%. We identified the age of patients, duration, and severity of T2DM as factors affecting mid-term diabetes remission. Nevertheless, further well-designed trials are needed to support our findings.

Eligibility and Awareness Regarding Metabolic Surgery in Patients With Type 2 Diabetes Mellitus in the Real-World Clinical Setting; Estimate of Possible Diabetes Remission.

Despite high-quality evidence highlighting metabolic surgery as an effective treatment option for type 2 diabetes mellitus (T2DM), the number of patients receiving bariatric surgery (BS) remains low. Since the introduction of the Diabetes Surgery Summit II (DSS-II) eligibility criteria, data on eligibility rates for BS in T2DM cohorts remain scarce. The aims of the present study were to examine in a real-world clinical setting: (i) what is the percentage of T2DM patients visiting diabetes outpatient clinics who meet the DSS-II eligibility criteria, (ii) how many of these have been informed about the option of BS, and (iii) what are the characteristics associated with eligibility and awareness of BS. Demographic, anthropometric, clinical and socioeconomic data were obtained for all patients with T2DM who were consecutively examined in the outpatient clinics of three large-volume university hospitals (n = 1167). A medical registry form was completed to screen for BS eligibility. Patients were considered eligible if the recommendation by DSS-II criteria was either to “consider” or “recommend” BS. Eligible patients were further inquired whether they had ever been informed about the option of BS by their physicians. The advanced DiaRem score (ADRS) was applied to eligible patients to assess their probability of achieving postoperative T2DM remission. A significant percentage of T2DM patients who are routinely assessed in outpatient clinics meet the DSS-II eligibility criteria (15.3%). Eligible patients are younger and more obese, have a shorter T2DM duration, worse glycaemic control and better renal function, compared to non-eligible ones. Among eligible patients, only 39.3% have been medically informed about the option of BS. Informed patients are younger and more severely obese than non-informed ones. A significant percentage of non-informed patients (35%) have an ADRS ≤10, indicating a considerable probability for T2DM remission after BS, and are thus deprived of this opportunity due to lack of appropriate medical counseling. Screening and awareness of BS remain an unmet need in current T2DM management. Future research should focus on intensifying screening for BS eligibility at every medical visit and promoting evidence-based clinical recommendations for patients expected to benefit the most.

1993-P: Impact of Laparoscopic Sleeve Gastrectomy on Glycemic Control in Japanese Patients with Obesity and Type 2 Diabetes

Background and Aims: Metabolic surgery has been proven to be effective for improving long-term outcome in patients with obesity and T2DM in Western countries. We aimed to evaluate the effects of this treatment in Japanese patients. Methods: We enrolled Japanese patients with obesity and T2DM who underwent laparoscopic sleeve gastrectomy (LSG) in our hospital from October 2016 to November 2019. We compared changes in body weight, HbA1c, antidiabetic drugs, and various metabolic parameters from preoperative baseline and 6 months after LSG. Results: Fifty-one patients with obesity underwent LSG; 26 had T2DM (age, 46.2±9.2 years; duration of diabetes, 9.5±7.4 years; female sex, 65.0%). Patients’ body weight, BMI and HbA1c decreased significantly (108.1±16.7 to 88.4±15.7 kg, 39.9±5.8 to 32.7±5.9 kg/m2 and 7.4±1.2 to 6.0±0.8%, respectively). The number of antidiabetic drugs significantly decreased postoperatively (2.1±1.2 to 0.6±1.0). Among them, 18 patients completely discontinued antidiabetic drugs. And all of five patients on insulin preoperatively maintained good glycemic control without insulin injections after LSG. The T2DM remission rate (HbA1c &amp;lt; 6.5% and no antidiabetic medications for 6 months) was 76.9%. ROC curve analysis revealed that the remission rates were low in patients with preoperative mABCD score ≤ 5 and DiaRem score ≥ 6. Dyslipidemia, hypertension and liver enzyme elevation improved significantly after LSG as well. There were no serious complications related to LSG; one patient experienced suture failure. Conclusion: LSG for Japanese patients with obesity and T2DM improved both body weight and glycemic control, as well as other various metabolic-related diseases. Six months after LSG, the T2DM remission rate was comparable in Japanese patients to Westerns. In addition, LSG significantly reduced the amount of antidiabetic drugs, suggesting that LSG has some advantage in healthcare costs. Disclosure Y. Oe: None. T. Takase: None. K. Cho: None. A.

Performance and improvement of the DiaRem score in diabetes remission prediction: a study with diverse procedure types.

The DiaRem score has proven to be a reliable predictor tool for diabetes remission in Roux-en-Y gastric bypass (RYGB), as well as laparoscopic adjustable gastric band (LAGB) and laparoscopic sleeve gastrectomy (LSG). To our knowledge there are no studies that analyze DiaRem in patients undergoing biliopancreatic diversion with duodenal switch (BPD/DS). To test the validity of the DiaRem score as a predictor of type 2 diabetes remission at 1 year post surgery in patients who underwent LABG, LSG, RYGB, and BPD/DS, as well as to develop and test a novel model that uses DiaRem to predict type 2 diabetes remission by procedure type (LABG, LSG, RYGB, and BPD/DS). University Medical Center, United States. A retrospective review of institutional records identified patients who underwent primary bariatric procedures (LAGB, LSG, RYGB, and BPD/DS) between January 1, 2000 to April 10, 2017, had a diagnosis of diabetes and had complete preoperative and 1-year postoperative follow-up information. A univariable logistic regression model was fit to assess the association between DiaRem score and diabetes remission. A multivariable logistic regression model was created, including procedure type and other preoperative characteristics. The area under the receiver operating curve (AUROC) was calculated to analyze the performance of both models for the entire cohort as well as a BPD/DS only subgroup. A total study cohort of 602 was obtained. The majority of patients underwent RYGB (456; 75.7%), followed by LSG (84; 14.0%), BPD/DS (35; 5.8%), and LAGB (27; 4.5%). The multivariable regression model with RYGB as the reference procedure, showed that BPD/DS results in higher odds of type 2 diabetes remission at 1 year post surgery (adjusted odds ratio [OR] 3.29, 95% confidence interval [CI] 1.27, 8.51), while LSG (adjusted OR .52, 95%CI .29, .93) and LAGB resulted in lower odds (adjusted OR.23, 95% CI.09,.60). The univariable DiaRem model and the novel model were determined to be moderately strong in classifying diabetes remission in the entire cohort (AUROC: .79, 95% CI: .75, .83 and .82, 95% CI: .79, .85, respectively) as well as in the BPD/DS sub-group (AUROC: .85, 95% CI: .70, .99 and .84, 95% CI .69, .99, respectively). Our study shows that the DiaRem score is a reliable tool to predict diabetes remission, amongst a wide variety of different procedures as well as specifically those receiving BPD/DS. Our novel model, which takes into account procedure type, not only shows that BPD/DS patients have thehighest odds of diabetes remission than other procedures, but also that this model performs significantly better at predicting diabetes remission than DiaRem alone.

Bariatric surgery is safe and effective in Medicare patients regardless of age: an analysis of primary gastric bypass and sleeve gastrectomy outcomes

BackgroundNumerous studies have shown that bariatric surgery in older patients is safe and effective. However, both the Agency for Healthcare Research and Quality (AHRQ) and a Medicare Evidence Advisory Committee (MEDCAC) have cited gaps in the evidence for outcomes in Medicare patients undergoing bariatric surgery. These gaps are predominantly in the safety and outcomes evidence in Medicare patients younger than 65 years old (Centers for Medicare and Medicaid Services [CMS] < 65). ObjectivesThe aim of our study was to review both the safety and efficacy of gastric bypass (RYGB) and sleeve gastrectomy (SG) in Medicare patients compared with other payers. SettingA single academic medical center. MethodsA prospectively maintained database of 3300 patients who underwent bariatric surgery between January 2007 and December 2017 was utilized. The outcomes of Medicare patients undergoing RYGB and SG were analyzed and compared to those of similar patients covered by Medicaid or Commercial insurers. ResultsThere were too few patients with commercial insurance older than 65 to compare to those with Medicare (CMS ≥ 65). Mortality at 90 days for CMS ≥ 65 was 1.3% and the overall complication rate was 20.1% (minor 15.6%; major 7.1%). Total weight loss (TWL) at 6 months and 1, 2, and 3 years was 25.3%, 30.0%, 29.9%, and 29.4% respectively. For any time after surgery, 23% of CMS ≥ 65 had complete remission of diabetes and 45% had partial remission.Demographic analysis of CMS < 65 found Medicare patients were significantly older with more diabetes, hypertension and hyperlipidemia than those with commercial payers. Mortality at 90 days for CMS < 65 was 0.6% and the overall complication rate was 18.3% (minor 14.3%; major 4.7%). Mortality was not significantly different between payers. After adjustment for baseline differences and comparing to the Medicare group, the commercial group was less likely to have minor complications (P = .019), any complications (P = .007), and extended length of stay (P < .001). The TWL for the entire cohort age <65 at 6 months and 1, 2, and 3 years was 28.1%, 34.1%, 34.1%, and 31.8% respectively. After adjusting for differences, there was no significant difference in TWL between payers. For any time after surgery, complete remission of diabetes was 45% in CMS < 65 patients and partial remission was 59%. The comparison of remission between groups was then adjusted for DiaRem score and surgery type. CMS < 65 patients had significantly less partial remission of diabetes than commercial patients (P = .034) but no difference in complete remission. ConclusionsRYGB and SG are both safe and effective in Medicare patients of all ages. CMS ≥ 65 have acceptable mortality and complication rates with TWL and diabetes remission similar to younger patients. CMS < 65 patients are older than those with commercial insurance with more comorbid disease. While they have longer hospital stays after bariatric surgery, their weight loss and complete remission of diabetes are no different than patients with Medicaid or commercial insurance. This study helps fill an important evidence gap in bariatric surgical patients raised by both Agency for Healthcare Research and Quality, and a Medicare Evidence Advisory Committee.

Discordance in prediction for prognosis of type 2 diabetes after metabolic surgery: comparison of the ABCD, DiaRem, and individualized metabolic surgery models.

PurposeMetabolic surgery has been performed as a treatment option for uncontrolled type 2 diabetes (T2D), and several scoring systems for predicting postoperative T2D remission have been proposed. This study was designed to assess consistency of 3 existing scoring systems in patients with T2D duration <1 year.MethodsThis study included 186 patients with T2D enrolled in a university hospital prospective database between 2011 and 2013. Externally validated scoring systems for predicting T2D prognosis after metabolic surgery were identified and selected through systematic literature search. We assessed concordance between ABCD, DiaRem, and individualized metabolic surgery (IMS) scores in participants using kappa statistical analysis and 1-way analysis of variance.ResultsOf the participants, 52 and 82 patients were expected to have favorable T2D remission after metabolic surgery with ABCD score of 10–5 and DiaRem score of 0–7, respectively, and a slight-to-fair concordance was shown between the 2 scoring systems (kappa measure, 0.07; standard error [SE], 0.05 and kappa measure, 0.25; SE, 0.19, respectively). The DiaRem score increased with T2D severity determined by IMS score (P < 0.001), while the ABCD score showed no significant association with IMS score.ConclusionABCD and DiaRem scores showed significant discordance when applied to potential metabolic surgery candidates in whom postoperative T2D remission rate was highly expected. The IMS score showed a dose-response association with DiaRem score but had no significant association with the ABCD score.

A 5-dimension patient education program targeting type 2 diabetes remission

Introduction: Type 2 diabetes (T2D) reversal has been demonstrated in patients undergoing bariatric surgery or low caloric diets. Objective: To investigate the effects of therapeutic patient education alone on T2D reversal in early diagnosed patients. Methods: Seventeen T2D patients underwent a one-week therapeutic education program, followed by 12 months of 1 hour sessions every month, targeting diabetes reversal. This reversal was determined using the DiaRem score which integrates glycated hemoglobin levels and antidiabetic drug treatment. Patient’s conceptions, perceptions and motivation were assessed using a 5-dimensional psychopedagogic score. Results: After 1 year, the mean HbA1C fell from 7.2% (± 1.9) to 6.2% (± 0.8) (p &lt; 0.05), antidiabetic drug doses decreased by 25% (p &lt; 0.05), and the DiaRem score increased by 15% (p &lt; 0.01), indicating a reversal of the disease, not correlated to weight loss. At the end of the study, 15 out of 17 patients had excellent glycemic control (HbA1C &lt; 7.0%) and 4 patients had parameters compatible with partial diabetes remission. A significant improvement in glycemic control coupled with a lowering of antidiabetic drug treatment was observed. Conclusions: Following an initial therapeutic education program and regular consultation sessions thereafter, early diagnosed patients may reverse their type 2 diabetes.

A167 - DiaREM scores predict diabetes remission after bariatric surgery

Background: Bariatric surgery has been proven to be highly effective in controlling diabetes. However, not all patients who undergo the procedure achieve diabetes remission. The DiaREM score has been used to predict diabetes remission in patients with RYGB, but there are no studies that show its performance amongst the other bariatric surgery procedures.

A5143 - DiaRem Score Association with Remission of Type 2 Diabetes Following Modified Duodenal Switch

Bariatric surgery is an established treatment of type 2 diabetes mellitus (T2DM). Meta-analysis suggests more positive outcomes following duodenal switch (DS) but DS modifications are largely unstudied. The DiaRem score uses a 4 variable (insulin and antidiabetic medication use, age, and HbA1c) algorithm to predict the probability of T2DM remission following Roux-en-Y gastric bypass (RYGB) based on well-defined probability ranges; lower scores correspond to greater probability of T2DM remission following RYGB.
