Zhou X, Ke Z, Sun F, Li F, You Z, Zhang J, Gao Y, Zhu Z, Tong W. Effect of Bariatric Surgery on Metabolic Syndrome in Chinese Patients with Low Body Mass Index: a Propensity Score Matching Study. 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.

Sex-Specific Changes in Body Composition Following Metabolic and Bariatric Surgery Are Associated with the Remission of Metabolic Syndrome. Obes Surg 2023; 33:2780-2788. [PMID: 37481470 DOI: 10.1007/s11695-023-06741-w] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2023] [Revised: 06/30/2023] [Accepted: 07/14/2023] [Indexed: 07/24/2023]
Abstract
PURPOSE Metabolic and bariatric surgery (MBS) is the most effective treatment for metabolic syndrome (MetS). However, the mechanism of MetS remission after MBS remains unclear. We aimed to explore the relationship between sex differences, body composition, and the remission of MetS after MBS. MATERIALS AND METHODS Cross-sectional study of 80 patients with obesity and MetS who underwent MBS with case-control design. The International Diabetes Federation criteria were used to define MetS. Body composition was measured using dual-energy X-ray absorptiometry before and 1 year after the operation. In addition to calculating changes in MetS and its prevalence, we performed a multiple logistic regression to determine predictors of MetS remission. RESULTS There were significant differences in body composition between males and females after MBS. Both males and females had significant improvements in the overall prevalence of MetS, decreasing from 100 to 21.74% (P <0.001) and from 100 to 35.29% (P <0.001), respectively. A higher percentage of visceral adipose tissue (VAT) reduction tends to be associated with a higher chance of MetS remission in men. In females, the MetS nonremission subgroup had a higher %Trunk lean body mass (LBM), and %Android LBM reduction than the remission subgroup, but the multiple logistic regression analysis result was not statistically significant. CONCLUSION After MBS, reduced VAT might be related to MetS reversibility in males, while reduced LBM may result in MetS nonremission in females.

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
Bariatric surgery has become increasingly common due to the worldwide obesity epidemic. A shift from open to laparoscopic surgery, specifically, laparoscopic sleeve gastrectomy (LSG), has occurred in the last two decades because of the low morbidity and mortality rates of LSG. Although LSG is a promising treatment option for patients with morbid obesity due to restrictive and endocrine mechanisms, it requires modifications for a subset of patients because of weight regain and tough complications, such as gastroesophageal reflux, strictures, gastric leak, and persistent metabolic syndrome., Revision surgeries have become more and more indispensable in bariatric surgery, accounting for 7.4% in 2016. Mainstream revisional bariatric surgeries after LSG include Roux-en-Y gastric bypass, repeated sleeve gastrectomy, biliopancreatic diversion, duodenal switch, duodenal-jejunal bypass, one-anastomosis gastric bypass, single anastomosis duodeno-ileal bypass (SAID) and transit bipartition. This review mainly describes the revisional surgeries of LSG, including the indication, choice of surgical method, and subsequent effect.

Abstract
Metabolic syndrome (MS) is defined as the constellation of obesity, insulin resistance, high serum triglycerides, low high-density lipoprotein cholesterol, and high blood pressure. It increasingly affects more and more people and progressively evolves into a serious issue with widespread healthcare, cost, and quality of life associated consequences. MS is associated with increased morbidity and mortality due to cardiovascular or chronic liver disease. Conservative treatment, which includes diet, exercise, and antidiabetic agents, is the mainstay of treatment, but depends on patient compliance to medical treatment and adherence to lifestyle modification recommendations. Bariatric surgery has recently emerged as an appropriate alternative treatment with promising long-term results. Sleeve gastrectomy and Roux-en-Y gastric bypass constitute the most commonly performed procedures and have been proven both cost-effective and safe with low complication rates. Liver transplantation is the only definitive treatment for end-stage liver disease and its utilization in patients with non-alcoholic steatohepatitis has increased more than fivefold over the past 15 years. In this review, we summarize current state of evidence on the surgical treatment of MS.

Abstract
The prevalence of diabetes in China has increased rapidly from 0.67% in 1980 to 10.4% in 2013, with the aging of the population and westernization of lifestyle. Since its foundation in 1991, the Chinese Diabetes Society (CDS) has been dedicated to improving academic exchange and the academic level of diabetes research in China. From 2003 to 2014, four versions of Chinese diabetes care guidelines have been published. The guidelines have played an important role in standardizing clinical practice and improving the status quo of diabetes prevention and control in China. Since September 2016, the CDS has invited experts in cardiovascular diseases, psychiatric diseases, nutrition, and traditional Chinese medicine to work with endocrinologists from the CDS to review the new clinical research evidence related to diabetes over the previous 4 years. Over a year of careful revision, this has resulted in the present, new version of guidelines for prevention and care of type 2 diabetes in China. The main contents include epidemiology of type 2 diabetes in China; diagnosis and classification of diabetes; primary, secondary, and tertiary diabetes prevention; diabetes education and management support; blood glucose monitoring; integrated control targets for type 2 diabetes and treatments for hyperglycaemia; medical nutrition therapy; exercise therapy for type 2 diabetes; smoking cessation; pharmacologic therapy for hyperglycaemia; metabolic surgery for type 2 diabetes; prevention and treatment of cardiovascular and cerebrovascular diseases in patients with type 2 diabetes; hypoglycaemia; chronic diabetic complications; special types of diabetes; metabolic syndrome; and diabetes and traditional Chinese medicine.

Abstract
AIM To assess metabolic effects and safety of Roux-en-Y gastric bypass (RYGB) versus conventional medication (CM) in obese Chinese patients with type 2 diabetes (T2DM). METHODS This retrospective cohort study included 40 patients who underwent RYGB (mean age 44.1 years, body mass index [BMI] 33.3 kg/m2 ) and 36 patients administered CM (mean age 49.4 years, BMI 32.1 kg/m2 ). The primary endpoint was achievement of the triple endpoint (haemoglobin A1C [HbA1c] < 7.0%, low-density lipoprotein cholesterol < 2.6 mmol/L, and systolic blood pressure < 130 mmHg). Changes in weight, BMI, medication usage, complications, and adverse events were assessed. RESULTS After 1-year follow-up, 35% of RYGB patients and 8% of CM patients achieved the triple endpoint (P = 0.005). More patients in the RYGB group achieved complete (48% vs 3%, P < 0.001) and partial (23% vs 0%, P = 0.007) remission of diabetes, and complete remission of hypertension (58% vs 24%, P = 0.019). Patients in the RYGB group had greater weight loss and decrease in BMI, waist circumference, fasting and postprandial of blood glucose and insulin levels, HbA1c, blood pressure, triglycerides, and increased high-density cholesterol (P < 0.001- < 0.05). A lower proportion of the RYGB group received antidiabetics, antihypertensives, or antilipemic treatments, and had non-alcoholic fatty liver disease (NAFLD) than the CM group during follow-up. More patients had nutrient deficiency-related diseases in the RYGB group over 1-year follow-up. CONCLUSIONS For obese Chinese patients with T2DM, RYGB resulted in better metabolic control, greater weight loss, and lower medication usage and NAFLD, but more frequently resulted in diseases related to nutrient deficiency.

Decreased Leptin Is Associated with Alterations in Thyroid-Stimulating Hormone Levels after Roux-en-Y Gastric Bypass Surgery in Obese Euthyroid Patients with Type 2 Diabetes. Obes Facts 2019; 12:272-280. [PMID: 31079115 PMCID: PMC6696777 DOI: 10.1159/000499385] [Citation(s) in RCA: 17] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/28/2018] [Accepted: 02/25/2019] [Indexed: 12/23/2022] Open
Abstract
BACKGROUND Leptin has been shown to stimulate the hypothalamus-pituitary-thyroid (HPT) axis in vivo and vitro. Its role in thyroid axis regulation after weight loss induced by bariatric surgery is still unknown. The aim of this study was to evaluate the influence of leptin on weight loss and thyroid function variation induced by Roux-en-Y gastric bypass (RYGB) surgery in euthyroid individuals with obesity and type 2 diabetes mellitus (T2DM). METHODS 65 Chinese individuals with obesity and T2DM who underwent RYGB, and 27 healthy volunteers were enrolled in this retrospective study. Participants were evaluated for changes in anthropometric parameters, metabolic indexes, thyroid function, and leptin levels before and 12 months after surgery. RESULTS After RYGB, all of these patients experienced significant weight reduction and improved glucose control. Metabolic parameters were significantly ameliorated after surgery compared with baseline. Thyroid hormones including free triiodothyronine (FT3), free thyroxine (FT4), and thyroid-stimulating hormone (TSH) declined in parallel. Median (IQR) plasma leptin levels decreased from 33.7 ng/mL (17.9-63.1) to 10.3 ng/mL (4.0-18.5). Pearson correlation analysis showed that TSH was significantly positively correlated with body mass index, C-reactive protein (CRP), and leptin. Multiple stepwise linear regression indicated that leptin and CRP were independent factors affecting TSH. The β coefficients were 0.38 (p = 0.001) and 0.32 (p = 0.004), respectively. There was a significant positive correlation between ΔTSH and Δleptin (r = 0.33, p = 0.01). CONCLUSION Decreased or normalized TSH levels after weight loss induced by RYGB might be mediated by the decline in leptin. There could be cross talk between adipose tissue and the HPT axis.

Abstract
INTRODUCTION The Joint Committee for Developing Chinese Guidelines (JCDCG) introduced the Chinese definition for metabolic syndrome (MS), which has been verified in southern Chinese people but not in northwestern Chinese people. We evaluated the MS definition proposed by the JCDCG in a northwestern Chinese population, in comparison with those of the revised National Cholesterol Education Program Adult Treatment Panel III (NCEP-ATPIII) and the International Diabetes Federation (IDF). METHODS This population-based cross-sectional study was a part of the China National Diabetes and Metabolic Disorders Study conducted in Shaanxi province. We included 3243 participants aged ≥ 20 years. The age-adjusted MS prevalence was assessed per the 2007 Chinese population structure. The agreement between different definitions was assessed by the kappa statistic. RESULTS The standardized prevalence of JCDCG-MS, revised ATPIII-MS, and IDF-MS was 22.4%, 29.4%, and 24.9%, respectively. Among women, the agreement of the JCDCG definition with the revised ATPIII and the IDF definition was not good (κ = 0.599 and 0.601, respectively); 54.6% of the revised ATPIII-MS and 56% of the IDF-MS were defined as MS according to the JCDCG definition. Among men, the agreement of JCDCG definition with the revised ATPIII and IDF definitions was very good (κ = 0.863) and substantial (κ = 0.741), respectively. CONCLUSION The agreement of the JCDCG definition with the revised ATPIII and IDF definitions was insufficient in women. Compared with the other two definitions, the JCDCG definition underestimates MS prevalence in northwestern women.

Abstract
Insufficient hepatic O2 in animal and human studies has been shown to elicit a hepatorenal reflex in response to increased hepatic adenosine, resulting in the stimulation of renal as well as muscle sympathetic nerve activity and activating the renin angiotensin system. Low hepatic ATP, hyperuricemia, and hepatic lipid accumulation reported in metabolic syndrome (MetS) patients may reflect insufficient hepatic O2 delivery, potentially accounting for the sympathetic overdrive associated with MetS. This theoretical concept is supported by experimental results in animals fed a high fructose diet to induce MetS. Hepatic fructose metabolism rapidly consumes ATP resulting in increased adenosine production and hyperuricemia as well as elevated renin release and sympathetic activity. This review makes the case for the hepatorenal reflex causing sympathetic overdrive and metabolic syndrome in response to exaggerated splanchnic oxygen consumption from excessive eating. This is strongly reinforced by the fact that MetS is cured in a matter of days in a significant percentage of patients by diet, bariatric surgery, or endoluminal sleeve, all of which would decrease splanchnic oxygen demand by limiting nutrient contact with the mucosa and reducing the nutrient load due to loss of appetite or dietary restriction.

Abstract
OBJECTIVE To investigate the association between hypertriglyceridemic waist (HTGW) phenotype and arterial stiffness in a Chinese population without hypertension, diabetes and cardiovascular diseases. METHODS A total number of 3028 subjects aged 40 years and over were enrolled in this cross-sectional study. All participants provided a clinical history and underwent a physical examination. Brachial-ankle pulse wave velocity (baPWV) was used to evaluate arterial stiffness. HTGW phenotype was defined as the simultaneous presence of waist circumference ≥90/80 cm and triglycerides ≥2.0/1.5 mmol/L in men/women. RESULTS The prevalence of HTGW phenotype was 7.5% among healthy participants in China (Beijing), 7.4% in men and 7.5% in women. Women with HTGW phenotype had a higher level of baPWV compared with normal WC and normal triglyceride (NWNT) group (P < 0.05), but no significant difference was observed in men (P > 0.05). Multiple logistic regression analysis showed HTGW phenotype was significantly associated with baPWV after controlling for multiple factors in women. However, no significant relationship was observed in men. CONCLUSIONS The present study supports that HTGW phenotype is associated with increased arterial stiffness in women but not in men.
