Abstract
AIMS/HYPOTHESIS Roux-en-Y gastric bypass surgery (RYGB) frequently results in remission of type 2 diabetes as well as exaggerated secretion of glucagon-like peptide-1 (GLP-1). Here, we assessed RYGB-induced transcriptomic alterations in the small intestine and investigated how they were related to the regulation of GLP-1 production and secretion in vitro and in vivo. METHODS Human jejunal samples taken perisurgically and 1 year post RYGB (n=13) were analysed by RNA-seq. Guided by bioinformatics analysis we targeted four genes involved in cholesterol biosynthesis, which we confirmed to be expressed in human L cells, for potential involvement in GLP-1 regulation using siRNAs in GLUTag and STC-1 cells. Gene expression analyses, GLP-1 secretion measurements, intracellular calcium imaging and RNA-seq were performed in vitro. OGTTs were performed in C57BL/6j and iScd1-/- mice and immunohistochemistry and gene expression analyses were performed ex vivo. RESULTS Gene Ontology (GO) analysis identified cholesterol biosynthesis as being most affected by RYGB. Silencing or chemical inhibition of stearoyl-CoA desaturase 1 (SCD1), a key enzyme in the synthesis of monounsaturated fatty acids, was found to reduce Gcg expression and secretion of GLP-1 by GLUTag and STC-1 cells. Scd1 knockdown also reduced intracellular Ca2+ signalling and membrane depolarisation. Furthermore, Scd1 mRNA expression was found to be regulated by NEFAs but not glucose. RNA-seq of SCD1 inhibitor-treated GLUTag cells identified altered expression of genes implicated in ATP generation and glycolysis. Finally, gene expression and immunohistochemical analysis of the jejunum of the intestine-specific Scd1 knockout mouse model, iScd1-/-, revealed a twofold higher L cell density and a twofold increase in Gcg mRNA expression. CONCLUSIONS/INTERPRETATION RYGB caused robust alterations in the jejunal transcriptome, with genes involved in cholesterol biosynthesis being most affected. Our data highlight SCD as an RYGB-regulated L cell constituent that regulates the production and secretion of GLP-1.

Obes Surg 2023; 33:3051-3061. [PMID: 37561268 DOI: 10.1007/s11695-023-06765-2] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/15/2023] [Revised: 07/15/2023] [Accepted: 07/25/2023] [Indexed: 08/11/2023]
Abstract
BACKGROUND Bariatric surgery (BS) is known to improve the components of metabolic syndrome (MS) in patients with obesity. However, few studies have evaluated the effect of BS on patients with MS at low BMI levels. The study aims to assess the effect of BS on MS in patients with low BMI by comparing BS with medical therapy (MT). METHODS A total of 271 patients with MS who underwent BS and MT at a single institution were reviewed in this retrospective cohort study. A 1:1 propensity score matching was performed for the BS and MT groups with BMI<35 kg/m2. We analyzed the 5 years effect of BS versus MT on the remission of MS, its components, atherosclerotic cardiovascular disease (ASCVD) risk, and medication used. RESULTS Patients in the MT group showed a decrease in the prevalence of MS to 62% at the 1st year and 10% at the 5th year. In the BS group, MS prevalence in patients with BMI<35 kg/m2 decreased to 30% and 9% at the 1st and 5th year, whereas in patients with BMI≥35 kg/m2 was 26% and 7%, respectively. The 10-year ASCVD risk and the lifetime ASCVD were significantly decreased 5 years after BS in patients with BMI<35 kg/m2. The number and daily drug dose of hypoglycemic drugs, antihypertensive medications, and lipid-lowering drugs were reduced from baseline in both BS and MT groups. CONCLUSION Bariatric surgery significantly improves MS remission rates and long-term cardiovascular risk in Chinese patients with metabolic syndrome and a BMI <35 kg/m2.

Abstract
Obesity is a leading cause of hypertension (i.e., high blood pressure [BP]). While hypertension can be managed with antihypertensive medication, substantial weight loss can also lower BP, reducing the need for antihypertensive medication. Articles in this review (n = 60) presented data on antihypertensive medication use among adults pre- and postoperatively. Roux-en-Y gastric bypass was the most studied surgical approach followed by Laparoscopic Sleeve Gastrectomy. Antihypertensive medication was discontinued in a large proportion of patients after surgery, and the mean number of antihypertensive medications decreased by approximately one. In almost a third of the studies, over 75% of participants experienced hypertension remission. All articles aside from two reported a decrease in systolic BP, with about 40% reporting a decrease of ≥ 10 mm Hg.

Abstract
BACKGROUND Metabolic syndrome (MetS) is common among morbidly obese patients undergoing bariatric surgery. The aim of this study is to analyse prevalence and evolution of MetS in patients suffering from morbid obesity, before and after bariatric surgery, during a follow-up period of 5 years. METHODS A before-after study was carried out including 156 patients with MetS. The definition of metabolic syndrome according to the Joint Interim Statement (JIS) definition was used. Demographic, as well as anthropometric, biochemical, and clinical analyses were assessed before, as well as 2 and 5 years after performing laparoscopic Roux-en-Y gastric bypass (RYGB). RESULTS High BMI (100%), elevated blood pressure (78%) and low levels of high density lipoprotein (70%) were the most prevalent criteria for MetS. The percentage of people with MetS decreased significantly to 48.9% at 2 years and 24.1% at 5 years. The weight was also significantly reduced at 2 years, although at 5 years a rebound effect is already observed. Percentage of total weight loss (%TWL) and excess BMI loss (%EBMIL) were. 49.7 ± 19.4% and 68.2 ± 18.9%, respectively, at 2 years and 29.3 ± 11.6% and 62.0 ± 24.9 at 5 years, both presenting significant differences (p < 0.001). CONCLUSION RYGB in obese patients is associated with a significant improvement of MetS and its comorbidities. Insufficient weight loss is the main factor related to the prevalence of MetS.

Abstract
BACKGROUND Bariatric surgery is known to decrease weight and the prevalence of comorbidities, but there is little evidence on the differential effect of Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) on the remission of the aggregate outcome, metabolic syndrome, 4 years after surgery. The purpose of this study was to determine the effectiveness of RYGB and SG on metabolic syndrome in veterans. METHODS We retrospectively reviewed consecutive patients who underwent SG and RYGB at the Dallas Veterans Affairs Medical Center from 2003 to 2012. We determined the effect of both the operations on the remission of metabolic syndrome, its individual components, and medium-term morbidity and mortality. A sensitivity analysis was performed using propensity matching. RESULTS A total of 266 patients were identified (159 RYGB and 107 SG) with 96% follow-up after 4 years. The mean age of the cohort was 51.4 years; the majority of patients were male (59%) and Caucasian (69%). RYGB patients had a greater mean body mass index and were more likely to have hypertension or hypertriglyceridemia. RYGB was associated with a similar metabolic syndrome remission to SG (37.6% vs 26.8%; P=0.09). The percentage of weight loss was 26.5% after RYGB and 10.8% after SG at 4 years post operation (P<0.01). Predictors of metabolic syndrome persistence were male gender, type 2 diabetes, and low high-density lipoprotein. While both the operations were associated with similar mortality (RYGB 4.4%, SG 2.8%; P=0.74), RYGB was associated with a greater rate of morbidity. CONCLUSION RYGB and SG seem to be associated with similar remission rates of metabolic syndrome at 4 years. RYGB yields greater weight loss with greater medium-term complications.

Abstract
OBJECTIVES the aim of this study was to evaluate the efficacy of Roux-en-Y Gastric Bypass (RYGB), compared with nonsurgical treatment (NS group), as an instrument for inducing remission of co-morbidities related to Metabolic Syndrome (MetS) in patients with Obesity, grades 2 and 3 (Ob2,3). METHODS two hundred and fifty eight Ob2,3 patients were selected in a retrospective analysis and included in a case control study. MetS was defined as described by the International Diabetes Federation. One hundred and twenty-nine of these patients underwent RYGB (S group), and 129 were assessed as an NS group. RESULTS at baseline, S and NS groups did not differ in BMI, age, female sex and prevalence of MetS (p>0.05). For the S group the outcomes were a reduction in BMI of 38.1% (p<0.001), waist circumference of 28.6% (p<0.001), fasting plasma glucose of 10.5% (p<0.001), serum LDL-cholesterol of 21.9% (p<0.001) and of 85% in the number of patients with MetS (p<0.001). For the NS group, only a decrease of 4.12%(p=0.047) in triglyceride levels and of 5.9%(p=0.031) in Diastolic Blood Pressure was observed. In the NS group, 98.6% of the patients continued to have MetS. The number needed to treat (NNT) with surgery to resolve one case of MetS was 1.2 (CI 95%: 1.1 - 1.4). CONCLUSION in the real world, in the South of Brazil, compared with NS treatment and after 1 year of observation, RYGB is highly effective for decreasing the prevalence of MetS.

Abstract
BACKGROUND Bariatric surgery has proven to provide durable weight loss and control of comorbid conditions, including the metabolic syndrome (MS). Existing definitions of MS have caused substantial confusion regarding their concordance for identifying the same individuals. The aim of this study was to assess the value of 2 different diagnostic guidelines criteria (National Cholesterol Education Adult Treatment Panel III [ATP III] and International Diabetes Federation [IDF]) for the evaluation of remission of MS after Roux-en-Y gastric bypass (RYGB). PATIENTS AND METHODS A cohort of 381 patients who underwent a primary RYGB, satisfied the criteria for MS, and had at least o1 postoperative visit were selected. Weight loss and MS remission were analyzed 6 and 12 months after surgery by ATP III and IDF criteria. RESULTS Before surgery, 381 (48.9%) and 354 (45.4%) patients fulfilled the criteria for MS according to the ATP III and IDF, respectively. According to the ATP III definition, remission of MS after bariatric surgery occurred in 209 of 239 (87.4%) and 98/102 (96.1%) patients at 6 and 12 months, respectively. According to the IDF definition, this occurred in 180 of 232 (77.6%) and 54 of 64 (84.4%) at the same time periods. On the basis of different percentage of excess body weight loss cut-off values, the area under the curve in receiver operating characteristic analysis at 12 months was slightly better for ATP III (0.77) than IDF criteria (0.68) for remission of MS. CONCLUSIONS With the use of the IDF definition, the remission rate of MS was 10% more rigorous than with use of the ATP-III criteria. This feature is attributable to a greater discrimination of patients with high blood pressure, glycemia, and dyslipidemia. The IDF criteria seem more accurate to evaluate MS remission.

Abstract
Background Early detection and treatment of the metabolic syndrome may prevent diabetes and cardiovascular disease. Our aim was to assess remission of the metabolic syndrome and its determinants after a population based screening without predefined intervention in the Netherlands. Methods In 2006 we detected 406 metabolic syndrome cases (The National Cholesterol Education Program’s Adult Treatment Panel III (NCEP ATP III) definition) among apparently healthy individuals with an increased waist circumference. They received usual care in a primary care setting. After three years metabolic syndrome status was re-measured. We evaluated which baseline determinants were independently associated with remission. Results The remission rate among the 194 participants was 53%. Baseline determinants independently associated with a remission were the presence of more than three metabolic syndrome components (OR 0.46) and higher levels of waist circumference (OR 0.91), blood pressure (OR 0.98) and fasting glucose (OR 0.60). Conclusions In a population with screen-detected metabolic syndrome receiving usual care, more than half of the participants achieved a remission after three years. This positive result after a relatively simple strategy provides a solid basis for a nation-wide implementation. Not so much socio-demographic variables but a higher number and level of the metabolic syndrome components were predictors of a lower chance of remission. In such cases, primary care physicians should be extra alert.

Abstract
BACKGROUND The link between diabetes mellitus and gastroesophageal reflux disease (GERD) is controversial. We assessed the relationship between glycemic control (GC) and GERD in morbidly obese patients. METHODS Consecutive patients with morbid obesity (n = 86) underwent manometry, pH-metry, endoscopy, and contrasted X-ray after responding to a GERD questionnaire and dosing fasting plasma glucose (FPG) and glycated hemoglobin (HbA1c). Patients with poor GC (HbA1c, 6.1-10% and FPG < 140 mg/dl) and those with very poor GC (HbA1c > 10% or FPG > 140 mg/dl) were compared. RESULTS There were 63 patients with poor GC and 17 with very poor GC. Compared to patients with very poor GC, patients with poor GC showed higher heartburn scores [8 (0-12) vs. 0 (0-4); P = 0.003]; higher total esophageal acid exposure [5.2% (2.5-10.5%) vs. 2.3% (0.8-7.5%); P = 0.041]; lower distal esophageal amplitude (105 ± 38 vs. 134 ± 63 mmHg; P = 0.019); higher expiratory gastroesophageal pressure gradient (GEPG, 7 ± 3.4 vs. 5.2 ± 3 mmHg; P = 0.050); lower ventilatory gradient (inspiratory-expiratory GEPG, 10.9 ± 3.8 vs. 13.6 ± 4.1 mmHg; P = 0.012); lower waist-to-hip ratio (0.95 vs. 1; P = 0.040); and more hiatal hernia (38% vs. 6%; P = 0.016). CONCLUSIONS This study suggests an inverse relation between glycemic control and GERD in morbidly obese patients. This can be partially explained by a lower frequency of hiatal hernia in patients with very poor glycemic control.

Abstract
OBJECTIVES To evaluate the relations between liver markers (GGT, ALT and AST) and the metabolic syndrome (and its components) in morbidly obese subjects, and to determine the response of these metabolic factors and hepatic enzymes after weight loss induced by Roux-en-Y gastric bypass. METHODS This study was carried out at a university hospital, in Santo André (SP), Brazil. We evaluated 140 morbidly obese subjects aged from 18 to 60 years submitted to a Roux-en-Y gastric bypass, who were followed for a mean period of 8 months. Patients with a history of heavy drinking, type 1 diabetes, and/or liver disease were excluded. RESULTS Liver markers, most notably GGT, were strongly associated with metabolic abnormalities, mainly hyperglycemia. The prevalence of type 2 diabetes significantly increased with increasing levels of GGT (highest versus lowest quartile GGT: odds ratio 3.89 [95%CI: 1.07-14.17]). Liver markers significantly decreased 8 months after the Roux-en-Y gastric bypass and the reduction of GGT levels were associated with the reduction of glucose levels (Pearson r = 0.286; p = 0.001). CONCLUSIONS Elevated levels of liver markers, principally GGT, in morbidly obese subjects are associated with metabolic abnormalities. In addition to the well-known benefits of bariatric surgery, Roux-en-Y gastric bypass, reduced the levels of liver markers to the normal range.

Abstract
OBJECTIVE: The purpose of the study was to investigate the prevalence of hyperuricemia in morbidly obese subjects before and after Roux-en-Y gastric bypass (RYGBP) and its relationship with metabolic syndrome abnormalities. SUBJECTS AND METHOD: We evaluated 420 morbidly obese patients. Pre and postoperative (8 months after RYGBP) blood samples were drawn. Obese patients underwent laparoscopic RYGBP and after eight months all the tests were repeated. RESULTS: The overall prevalence of hyperuricemia was 34.28%. Hyperuricemia was more common in men than in women (51.72 vs. 29.72%; p = 0.0002). Men with hyperuricemia were more likely to have diabetes (p = 0.034) and more elevated fasting plasma glucose levels (p = 0.027). Women with hyperuricemia were more likely to have hypertension (p = 0.003), metabolic syndrome (p = 0.001), elevated triglycerides (p = 0.001) and GGT (p = 0.009), and decreased HDL (p = 0.011). After surgery, uric acid levels decreased from 5.60 ± 1.28 to 4.23 ± 1.20 (p < 0.0001). The prevalence of hyperuricemia decreased from 33.6% to 6.4% (p < 0.0001), in men from 48.3% to 17.2% (p < 0.0001) and in women from 29.7% to 3.6% (p < 0.0001). CONCLUSION: Concentrations of uric acid were associated with the prevalence of metabolic abnormalities in this sample of morbidly obese patients. Also, weight loss after RYGBP can reduce uric acid levels and the prevalence of hyperuricemia.

Abstract
PURPOSE OF REVIEW Diabetes resolves in 80% of individuals undergoing successful Roux-en-Y gastric bypass. Absolute caloric restriction alone resulting from gastric anatomic changes indeed leads to weight loss; however, immediate effects in glycemic control often precede substantial weight loss typically associated with insulin sensitivity. One putative explanation relates to hormonal effects accompanying Roux-en-Y gastric bypass. We reviewed the existing and recent literature to investigate the hormonal changes accompanying Roux-en-Y gastric bypass. RECENT FINDINGS Changes in levels of five candidate enteric hormones have been recently associated with early postoperative glycemic control following Roux-en-Y gastric bypass; the strongest effects are seen with variations in glucagon-like peptide-1, glucose-dependent insulinotropic peptide and ghrelin. SUMMARY The unique hybridization of static anatomic restriction and dynamic absorptive bypass lends a duality to the beneficial effects of Roux-en-Y gastric bypass. This duality likely explains the short-term and long-term resolution of diabetes in patients undergoing Roux-en-Y gastric bypass.

Percentage of excess BMI lost correlates better with improvement of metabolic syndrome after Roux-en-Y gastric bypass in morbidly obese subjects: anthropometric indexes and gastric bypass. Surg Obes Relat Dis 2008; 5:11-8.

Abstract
BACKGROUND The metabolic syndrome (MS) is a complex disorder characterized by a number of cardiovascular risk factors usually associated with central fat deposition and insulin resistance. Many different medical treatments are available for MS, including bariatric surgery, which improves all risk factors. The present study aimed to evaluate, at the Clinic of Gastroenterology and Obesity Surgery (Brazil), the accuracy of different anthropometric indexes and their correlation with improvement of the MS factors in the postoperative (6-month) period. METHODS This was a retrospective study of 140 patients who had undergone gastric bypass. Most of the patients were women (79.3%). The mean body mass index was 44.17 kg/m(2). We evaluated the weight of the subjects, the presence of diabetes mellitus and hypertension as co-morbidities, and the biochemical parameters. The anthropometric indexes tested included the percentage of excess weight loss, amount lost in kilograms, difference in the body mass index, percentage of initial weight lost, percentage of excess body mass index lost (%EBL), and percentage of initial fat mass lost. RESULTS The %EBL had a Spearman's correlation coefficient of 0.55 (P <.0001) for the difference between the MS factors before and after Roux-en-Y gastric bypass. The receiver operating characteristic curve for the %EBL resulted in an area under the curve of 0.846 (P = 0.0001) and a sensitivity and specificity of 100% and 61.29%, respectively, for a cutoff value of 64.55%. CONCLUSION The %EBL was the best method to report weight loss and the improvement in MS in morbidly obese subjects after Roux-en-Y gastric bypass.
