Abstract
Bariatric surgery is being undertaken more frequently in response to rising levels of obesity but is increasingly also requested as a cosmetic choice. Nutritional deficiencies are a recognised consequence of gastrectomy, with potentially severe and permanent neurological sequelae. We present two cases of acute, severe polyneuropathy following sleeve gastrectomy. Severe thiamine deficiency was considered in both cases but with delayed proof and a significant initial differential diagnosis. Neurologists must have a high index of suspicion for the peripheral as well as central presentations of thiamine deficiency to avoid permanent disability. We also call for explicit information resources warning of the risk and signs of thiamine deficiency to be provided routinely to patients after gastrectomy.

Nutrients 2024; 16:2226. [PMID: 39064668 PMCID: PMC11280029 DOI: 10.3390/nu16142226] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/26/2024] [Revised: 07/06/2024] [Accepted: 07/08/2024] [Indexed: 07/28/2024] Open
Abstract
INTRODUCTION Vitamin B1 (thiamine) deficiency (TD) after metabolic and bariatric surgery (MBS) is often insidious and, if unrecognized, can lead to irreversible damage or death. As TD symptoms are vague and overlap with other disorders, we aim to identify predictors of recurrent TD and failure to collect B1 labs. METHODS We analyzed a large sample of data from patients with MBS (n = 878) to identify potential predictors of TD risk. We modeled recurrent TD and failure to collect B1 labs using classical statistical and machine learning (ML) techniques. RESULTS We identified clusters of labs associated with increased risk of recurrent TD: micronutrient deficiencies, abnormal blood indices, malnutrition, and fluctuating electrolyte levels (aIRR range: 1.62-4.68). Additionally, demographic variables associated with lower socioeconomic status were predictive of recurrent TD. ML models predicting characteristics associated with failure to collect B1 labs achieved 75-81% accuracy, indicating that clinicians may fail to match symptoms with the underlying condition. CONCLUSIONS Our analysis suggests that both clinical and social factors can increase the risk of life-threatening TD episodes in some MBS patients. Identifying these indicators can help with diagnosis and treatment.

The Weight of Bariatric Surgery: Wernicke-Korsakoff Syndrome after Vertical Sleeve Gastrectomy-A Case Series. J Pers Med 2024; 14:638. [PMID: 38929859 PMCID: PMC11204981 DOI: 10.3390/jpm14060638] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/18/2024] [Revised: 06/05/2024] [Accepted: 06/08/2024] [Indexed: 06/28/2024] Open
Abstract
In this case series, the simultaneous occurrence of Wernicke's encephalopathy (WE) and dry beriberi was reported in three patients who underwent vertical sleeve gastrectomy (VSG) between May 2021 and May 2023. All patients were obese women who underwent vertical sleeve gastrectomy (VSG) without immediate postoperative complications, but two weeks later, hyperemesis and subsequent encephalopathy with ocular movement abnormalities and weakness were observed over the following thirty days. Patients were referred to neurology, where due to the high suspicion of WE, thiamine replacement therapy was initiated; meanwhile, diagnostic neuroimaging and blood tests were conducted. Neurological and psychiatric evaluations and neuroconduction studies were performed to assess the clinical evolution and present sequelae. One year after diagnosis, all patients exhibited affective and behavioral sequelae, anterograde memory impairment, and executive functioning deficits. Two patients met the criteria for Korsakoff syndrome. Additionally, peripheral nervous system sequelae were observed, with all patients presenting with sensorimotor polyneuropathy. In conclusion, Wernicke's encephalopathy requires a high diagnostic suspicion for timely intervention and prevention of irreversible sequelae, which can be devastating. Therefore, raising awareness among medical professionals regarding the significance of this disease is essential.

Abstract
Deficiency for thiamine (vitamin B1), traditionally assessed via the activity of the thiamine-dependent enzyme erythrocyte transketolase, has been reported in individuals with alcohol use disorder (AUD) and in people with HIV; concentrations of the metabolically active diphosphate form, however, have yet to be reported in HIV cohorts and results in AUD are equivocal. In this cross-sectional study, samples from 170 AUD, 130 HIV, and 100 healthy control individuals were analyzed to test the hypothesis that AUD and HIV groups relative to healthy controls would show low whole blood thiamine diphosphate (TDP) concentrations related to peripheral neuropathy. TDP concentrations were not different in the 3 study groups (P = .6141) but were lower in Black (n = 172) relative to White (n = 155) individuals (P < .0001) regardless of group. In a multiple regression, race relative to diagnoses explained more than 10 times the variance in whole blood TDP concentrations (F4,395 = 3.5, P = .0086; r2 = 15.1]. Performance on a measure of peripheral neuropathy (2-point discrimination) was worse in the HIV and AUD cohorts relative to the healthy control group (P < .0001) but was not associated with TDP concentrations. These findings suggest that Black individuals carry a heightened vulnerability for low whole blood TDP concentrations, but the clinical significance and mechanisms underlying these results remain to be determined.

Abstract
BACKGROUND Bariatric surgery has been associated with numerous micronutrient deficiencies. Several observational studies have found that these deficiencies are more common in racially/ethnically minoritized patients. OBJECTIVES To conduct a systematic review to investigate whether racially/ethnically minoritized patients experience worse nutritional outcomes after bariatric surgery. SETTING University of Wisconsin-Madison. METHODS PubMed, CINAHL, PsychINFO, and Cochrane databases were queried. We searched for manuscripts that reported micronutrient levels or conditions related to micronutrient deficiencies according to race/ethnicity (White, African American/Black, and Hispanic) after laparoscopic sleeve gastrectomy or Roux-en-Y gastric bypass between 2002 and 2022. Eleven micronutrients (vitamins A, B1 [thiamine], B12, D, E, K, calcium, copper, folate, iron, and zinc), and four conditions (anemia, bone loss, fractures, and hyperparathyroidism) were assessed. RESULTS Abstracts from 953 manuscripts were screened; 18 full-text manuscripts were reviewed for eligibility, and ten met the inclusion criteria. Compared to White patients, African Americans had a higher prevalence of thiamine, vitamin D, and vitamin A deficiencies. There were no differences in calcium and vitamin B12 deficiencies. The other six micronutrients were not assessed according to race/ethnicity. Hyperparathyroidism was more prevalent in African Americans than White patients in the three studies that evaluated it. The prevalence of fractures was mixed. Anemia and bone loss were not evaluated according to race/ethnicity. CONCLUSIONS Although the literature on micronutrient outcomes following bariatric surgery according to race/ethnicity is limited, African Americans appear to experience a higher prevalence of vitamin deficiencies and associated conditions. Qualitative and quantitative research to explore these disparities is warranted.

Abstract
BACKGROUND Thiamine deficiency (TD) among adolescents following metabolic and bariatric surgery (MBS) has not been assessed. OBJECTIVE We assessed TD among adolescents following MBS. SETTING University Hospital. METHODS A retrospective chart review was conducted for all adolescents and young adults (aged 10-25 years) who had MBS and subsequently presented with TD at our institution (n = 30). Diagnosis used clinical, laboratory, brain imaging, and neurophysiology criteria. Of 1575 patients, 7 subsequently had TD. Another 23 adolescents had MBS at private hospitals or overseas and presented at our institution with TD. RESULTS Based on MBS undertaken at our institution, TD prevalence was .45 cases per 100 MBS. The mean age of patients was 19.5 ± 3.23 years, 53.3% were male, 96.7% had sleeve gastrectomy, and time from MBS to admission averaged 4.97 ± 11.94 months. Mean weight loss from surgery to admission was 33.68 ± 10.90 kg. Associated factors included poor oral intake (90%), nausea and vomiting (80%), and noncompliance with multivitamins (71%). Signs and symptoms included generalized weakness, nystagmus, numbness, and paraparesis (83.3%-80%). Seven patients had Wernicke encephalopathy full triad; 16 displayed a mixed picture of Wernicke encephalopathy and dry beriberi; and there were no cases of wet beriberi. Half the patients achieved complete resolution of symptoms, whereas 47% and 40% had residual weakness or persistent sensory symptoms, respectively. There was no mortality. Most common concurrent nutritional deficiencies were of vitamins K, D, and A. CONCLUSIONS This is the first in-depth study of TD among adolescents after MBS. Although TD is uncommon among adolescents after MBS, it is serious, requiring diligent suspicion and prompt treatment. Bariatric teams should emphasize compliance with multivitamin regimens and follow it up.

Abstract
Thiamine deficiency is a life-threatening nutritional abnormality observed in the patients with obesity and following bariatric surgery. The aim of the present study is to determine the prevalence of thiamine deficiency prior to and after bariatric procedures. PubMed, Web of Science, Google scholar, CENTRAL, ProQuest, and Scopus were searched to retrieve relevant studies containing data on thiamine deficiency in patients with obesity who underwent bariatric surgery. A proportional meta-analysis approach was used to pool the prevalence of thiamine deficiency prior and after surgery. Our comprehensive literature search retrieved 41 studies with relevant data. The pooled prevalence of thiamine deficiency was 7% (95% CI: 4-12%) at baseline. We observed that 19% (95% CI: 0-68%), 9% (95% CI: 3-17%), and 6% (95% CI: 3-9%) of patients had developed thiamine deficiency at 3 months, 6 months, and 1 year after surgery, respectively. We also report that the prevalence of thiamine deficiency in pregnant women who had history of bariatric surgery. The rate was highest in the first trimester (12%) compared to that in the second (8%) and third (10%) trimesters. The baseline prevalence is 7% for thiamine deficiency in bariatric surgery candidates. The prevalence rate of thiamin deficiency increased to 19% and 9% 3 and 6 months after surgery; however, the rate decreased to 6% 1 year after surgery. Due to the higher prevalence of thiamine deficiency in the early post-operative phase, close monitoring during this period is recommended. A similar strategy should be implemented for pregnant women with history of bariatric surgery in their first trimester.

Abstract
Wernicke encephalopathy (WE) is an acute neurological disorder classically characterized by ataxia, ophthalmoplegia, and altered mental status. This is caused by thiamine deficiency and is usually seen in malnourished populations. However, with the advent and rise of bariatric surgery in the last 50 years, WE has become an increasingly recognized and potentially deadly complication. Here, we review the populations at risk, clinical presentation, and the incidence of WE in the bariatric surgery population from 1985 to 2023. While the predominant procedure shifts throughout the years, the overall incidence of WE per 100,000 cases for the following procedures are sleeve gastrectomy (1.06), gastric band (1.16), RYGB (4.29), and biliopancreatic diversion with duodenal switch (8.92). Thus, early intervention and post-operative supplementation is recommended to prevent WE.

Abstract
Wernicke's encephalopathy (WE) and Korsakoff Syndrome (KS) are distinct neurological disorders that may have overlapping clinical features. Due to the overlap, they are collectively known as Wernicke-Korsakoff syndrome. WE is related to diencephalic and mesencephalic dysfunction due to thiamine. WE typically manifests as confusion, ophthalmoplegia, nystagmus, and gait ataxia (Wernicke's triad), although they may not consistently occur together. Although WE mostly occurs in alcoholics, other etiologies, such as post-bariatric surgery, must be considered. Early diagnosis and therapy by intravenous thiamine are essential to prevent WE complications and to reduce morbidity and mortality. Therefore, physicians' and patients' awareness of WE is essential for early diagnosis and therapy. Accordingly, this narrative review aimed to provide an update on WE by reviewing articles published between April 2015 to April 2022 about the etiology, pathophysiology, diagnosis, and WE management updates. EMBASE, PubMed, Google Scholar, Google, and Scopus search engines were used to conduct the literature search.

Abstract
AIMS Bariatric surgery remains an effective treatment for the condition of obesity. However it predisposes patients to nutritional deficiencies and related complications. The aim of this study was to identify nutritional abnormalities, weight loss, adherence to supplements, and presence of gastrointestinal symptoms in a cohort of bariatric surgical patients. METHODS An analysis of the electronic medical records of patients attending a multidisciplinary private clinic in Sydney, Australia from August 2020 to August 2021 was conducted. Data on anthropometric measures, nutritional indices, adherence to supplements and gastrointestinal symptoms preoperatively and then at ≤6 months, 1 and 2 years or more postoperatively were collected. RESULTS A total of 231 patients were included in the study. The majority of patients were female (76.2%), with a sleeve gastrectomy (78.8%). Average preoperative BMI was 43.4 ± 7.1 kg/m2 . Weight loss ≥2 years postsurgery was 33.5 ± 12.4 kg. The most common abnormalities preoperatively were: C-reactive protein (47.7%), vitamin D (39%), B12 (31%), parathyroid hormone (27.6%) and ferritin (12.7%). Vitamin B12 (23.2%), parathyroid hormone (23%), vitamin D (17.7%) and ferritin (15.9%) remained common abnormalities postoperatively. Adherence to multivitamins was 90% in the first year following surgery, declining to 77% at ≥2 years. Gastrointestinal symptoms were predominantly present in the initial stages following surgery, manifesting thiamin deficiency in 6.5% of patients. CONCLUSIONS Despite achieving durable weight loss, nutritional and related abnormalities remain an ongoing challenge for bariatric surgery. Adherence to nutrient supplements, gastrointestinal symptoms and related complications are important considerations in addressing the problem.

Abstract
BACKGROUND Wernicke encephalopathy (WE) is an acute neurological disease resulting from vitamin B1 deficiency, and there are only very few case reports of WE after liver transplantation. The present study aimed to investigate the clinical characteristics, etiology, magnetic resonance imaging (MRI) features, treatment and prognosis of patients with WE after liver transplantation. METHODS Twenty-three patients with WE after liver transplantation from the First Affiliated Hospital, Zhejiang University School of Medicine and Jiangxi Provincial People's Hospital between January 2011 and December 2021 were retrospectively analyzed. RESULTS Among the 23 patients diagnosed with WE after liver transplantation, 6 (26%) had a classic triad of impaired consciousness, oculomotor palsy and ataxia, 17 (74%) had two features. The misdiagnosis rate was 65%. After treatment with high-dose vitamin B1, 19 (83%) patients showed improvement, whereas 4 showed no improvement, including 3 with residual short-term memory impairments and 1 with residual spatial and temporal disorientation and ataxia. CONCLUSIONS The misdiagnosis rate is high in the early stage of WE, and the prognosis is closely associated with whether WE is diagnosed early and treated timely. High-dose glucose or glucocorticoids can trigger WE and cannot be administered before vitamin B1 treatment. Vitamin B1 is suggested to be used as a prophylactic treatment for patients with WE after liver transplantation.

B1 Vitamin Deficiency After Bariatric Surgery, Prevalence, and Symptoms: a Systematic Review and Meta-analysis. Obes Surg 2022; 32:3104-3112. [PMID: 35776243 DOI: 10.1007/s11695-022-06178-7] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2022] [Revised: 06/21/2022] [Accepted: 06/22/2022] [Indexed: 10/17/2022]
Abstract
B1 deficiency is a very prevalent complication of bariatric surgery. This study reviews prevalence and symptoms of B1 vitamin deficiency after bariatric surgery. PubMed, Scopus, and Web of Science published were searched up to 10 Feb 2022, with the following keywords: Roux-en-Y gastric bypass, one anastomosis gastric bypass, Omega bypass, Mini bypass, Bariatric surgery OR Bariatric surgery, metabolic surgery, Weight loss surgery, Classic gastric bypass, Loop gastric bypass, Gastric Bypass, thiamine OR thiamin, beriberi, B1. A total of 11 studies examining 1494 patients were included in this meta-analysis. Twenty-seven percent of patients who underwent bariatric surgeries experience vitamin B1 deficiency. Thiamine supplements should be prescribed for the patients for the rest of their lives, and also standard post-surgery follow-ups are necessary in terms of monitoring dietary factors.

Abstract
Obesity in childbearing women leads to pregnancy-related complications such as gestational diabetes mellitus, pregnancy-associated hypertensive disorders, and macrosomia. Weight loss helps reduce these complications. Studies show bariatric surgery reduces obesity-related complications during and after pregnancy. However, bariatric surgery might be associated with adverse outcomes, such as low birth weight and small-for-gestational-age infants. In addition, several studies suggest pregnancy occurring less than a year post-bariatric surgery adversely affects pregnancy outcomes and causes micronutrients deficiency since the dramatic weight loss occurs in the first year. These adverse outcomes may lead to nutritional malabsorption, such as anemia and low vitamin B12 and folic acid levels. The review aims to overview obesity-related complications during pregnancy and the benefits and risks of bariatric surgery on pregnancy outcomes and maternal nutrition status.

Abstract
ABSTRACT Few studies have reported an increase in vitamin B12 (VitB12) levels after bariatric surgery. This study reports the phenomenon and adverse reactions of serum VitB12 elevation 1 month after surgery and explores the possible etiologies.Retrospective analysis was performed on VitB12 data for 112 patients from January 2018 to October 2019. Then, 87 patients were included between November 2019 and August 2020. They were divided into 2 groups according to the level of VitB12 after surgery, and the demographic and clinical data were analyzed. Then, LASSO regression model analysis and multiple logistic regression analysis were performed to explore the risk factors for VitB12 elevation after surgery.Retrospective data showed that the VitB12 level was significantly increased 1 month after surgery. Comparison of data between the 2 groups found that more patients also had diabetes in the nonelevated group. The postoperative folic acid and VitB12 levels of the elevated group were significantly higher than those of the nonelevated group. More patients had concurrent constipation in the elevated group than in the nonelevated group. Two meaningful variables in LASSO regression analysis were incorporated into the multivariate logistic regression analysis, and constipation was found to be an independent risk factor for the increase in VitB12 after surgery. Of the 199 patients in this study, 111 patients had elevated VitB12 levels after surgery. Among them, 7 patients had peripheral nerve symptoms.Constipation is an independent risk factor for increased VitB12 levels after surgery. High levels of VitB12 may cause some peripheral nerve symptoms. Therefore, it is necessary to pay attention to patients with postoperative constipation, monitor their VitB12 level as soon as possible, and take measures to improve constipation to avoid some adverse reactions caused by elevated VitB12 levels.

Clinical diagnosis, outcomes and treatment of thiamine deficiency in a tertiary hospital. Clin Nutr 2021; 41:33-39. [PMID: 34864453 DOI: 10.1016/j.clnu.2021.10.021] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/24/2021] [Revised: 10/09/2021] [Accepted: 10/29/2021] [Indexed: 11/23/2022]
Abstract
BACKGROUND Acute thiamine deficiency can occur in patients with or without history of alcohol abuse and can lead to life-threatening complications. Clinical diagnosis is challenging, often resulting in delayed recognition and treatment. Patients may present with heterogenous symptoms, more diverse than the historical neurological description. Cerebral MRI can contribute to the diagnosis in patients with neurological signs but it is not always feasible in emergency settings. Prompt parenteral supplementation is required to obtain the improvement of symptoms and avoid chronic complications. AIMS To describe the clinical presentation of reported cases of thiamine deficiency, assess prescription and results of cerebral imaging, review treatments that had been prescribed in accordance or not with available guidelines, and study the short-term outcome of these patients. METHODS This is a monocentric retrospective analysis of all reported cases of thiamine deficiency in a French tertiary hospital between January 1st 2008 and December 31st 2018. RESULTS Fifty-six cases were identified during the study period. Forty-five (80%) patients had a history of alcohol abuse. Most patients were diagnosed based on neurological symptoms but non-specific and digestive symptoms were frequent. Thirty-four percent of patients fulfilled clinical criteria for malnutrition. A brain MRI was performed in 54% of patients and was abnormal in 63% of these cases. Eighty-five percent of patients were treated by parenteral thiamine administration and the supplementation was continued orally in 55% of them. The majority of patients initially received 1000 mg daily of IV thiamine but the dose and duration of thiamine supplementation were variable. At the time of discharge, partial or complete improvement of symptoms was noted in 59% of patients. CONCLUSION This study highlights the clinical and radiological heterogeneity of thiamine deficiency. These observations should encourage starting thiamine supplementation early in patients with risk factors or suggestive symptoms even in non-alcoholic patients, and underline the importance of early nutritional support.

Abstract
We report a case of a 29-year-old woman admitted twice to our hospital with diabetic ketoacidosis (DKA) within 45 days following her bariatric surgery. The first admission required intensive care during her postoperative days after bariatric surgery. Subsequently, she continued to report high level of ketones on a daily basis. At her second admission, she presented with all three criteria of DKA. She was treated with a standard protocol for DKA, but ketones plasma level remained high despite significant improvement in pH and glycemic control. The administration of thiamine replacement was associated with normalization of the hyperketonemia. Thiamine deficiency can be associated with bariatric surgery and can lead to high ketone level in individuals with type 1 diabetes.

Abstract
We describe a case of Wernicke's encephalopathy secondary to thiamine (B1) deficiency in a patient status post-bariatric sleeve gastrectomy. The presenting symptoms of new-onset weakness, diplopia, and confusion in a young female patient raised suspicion for multiple sclerosis (MS), but given a history of bariatric surgery, thiamine levels were checked, revealing significant Vitamin B1 (thiamine) deficiency. This case highlights the importance of thorough history taking, as a misdiagnosis of MS in this case could have resulted in irreversible neurological deterioration and hematological and infectious consequences associated with the inappropriate administration of disease-modifying therapies. It is also important to note that severe vitamin deficiency occurred despite medication compliance.

Abstract
INTRODUCTION Thiamine is a water-soluble vitamin and is necessary for energy metabolism. Critically ill patients are at particular risk of developing thiamine deficiency and related complications. One of the complications that can occur is delirium. Delirium is a disorder that affects the body's response to treatment, length of stay in the ward, mortality, long-term cognitive impairment, and significantly increases treatment costs. In addition, studies show that delirium medication is more effective in preventing than in treating delirium. Given its low cost, availability, and minimal risk of side effects, thiamine supplementation could prove to be a relevant strategy in the prevention and treatment of delirium. METHODS PubMed, Cochrane Library, Ovid, and ClinicalTrials.gov databases were searched using relevant keywords that focus on the use of thiamine to prevent or treat delirium in critically ill patients. RESULTS Seven articles were included in the analysis. CONCLUSION The small number of studies and considerable heterogeneity prevent conclusions supporting the use of thiamine as an adjuvant in the prevention and treatment of delirium among critically ill patients. There is a need for high-quality, large-scale randomized clinical trials to confirm the beneficial effects of thiamine in the prevention and treatment of delirium.

Clin Gastroenterol Hepatol 2021; 19:1531-1537. [PMID: 33741500 DOI: 10.1016/j.cgh.2021.03.020] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/20/2020] [Revised: 01/20/2021] [Accepted: 03/12/2021] [Indexed: 02/06/2023]
Abstract
DESCRIPTION Endoscopic techniques are paramount in the identification and management of complications after surgery, though collaboration with other specialties is obligatory. Unfortunately, the evaluation and treatment algorithms are not standardized and there is a paucity of high-quality prospective studies to provide clarity regarding the best approach. The purpose of this clinical practice update is to apprise the clinician with respect to the endoscopic evaluation and management of patients with early (<90 days) complications after undergoing bariatric/metabolic surgery. METHODS The best practice advice outlined in this expert review are based on available published evidence, including observational studies and systematic reviews, and incorporates expert opinion where applicable. BEST PRACTICE ADVICE 1: Clinicians performing endoscopic approaches to treat early major postoperative complications should do so in a multidisciplinary manner with interventional radiology and bariatric/metabolic surgery co-managing the patient. Daily communication is advised. BEST PRACTICE ADVICE 2: Clinicians embarking on incorporating endoscopic management of bariatric/metabolic surgical complications into their clinical practice should have a comprehensive knowledge of the indications, contraindications, risks, benefits, and outcomes of each of the endoscopic treatment techniques. They should also have knowledge of the risks and benefits of alternative methods such as surgical and interventional radiological based approaches. BEST PRACTICE ADVICE 3: Clinicians incorporating endoscopic management of bariatric/metabolic surgical complications into their clinical practice should have expertise in interventional endoscopy techniques, including but not limited to: using concomitant fluoroscopy, stent deployment and retrieval, managing stenosis, and managing percutaneous drains. BEST PRACTICE ADVICE 4: Clinicians should screen all patients undergoing endoscopic management of bariatric/metabolic surgical complications and dietary intolerance for comorbid medical (nutrient deficiencies, infection, pulmonary embolism) and psychological (depression, anxiety) conditions. BEST PRACTICE ADVICE 5: Endoscopic approaches to managing complications of bariatric/metabolic surgery may be considered for patients in the immediate, early and late postoperative periods depending on hemodynamic stability. BEST PRACTICE ADVICE 6: Clinicians incorporating endoscopic management of bariatric/metabolic surgical complications into their clinical practice should have a detailed understanding of the pathophysiologic mechanisms initiating and perpetuating conditions such as staple-line leaks. This will allow for a prompt diagnosis and appropriate therapy to be targeted not only at the area of interest, but also any concomitant downstream stenosis. BEST PRACTICE ADVICE 7: Clinicians should recognize that the goal for endoscopic management of staple-line leaks are often not necessarily initial closure of the leak site, but rather techniques to promote drainage of material from the perigastric collection into the gastric lumen such that the leak site closes by secondary intention.

Abstract
The micronutrient status and optimal monitoring schedule after bariatric surgery have not been sufficiently assessed. This systematic review and meta-analysis investigated the longitudinal changes in micronutrient status after bariatric surgery. PubMed, EMBASE, and Cochrane Library were searched for articles that measured preoperative and postoperative serum micronutrient levels in patients undergoing Roux-en-Y gastric bypass (RYGB) or sleeve gastrectomy (SG). Among guideline-adherent studies, the longitudinal changes in micronutrient status were investigated using weighted mean difference (WMD) using a random-effects model. Among the 82 included studies, the guideline adherence rates for micronutrient supplementation after bariatric surgery did not exceed 20%. In patients supplemented per guidelines, vitamin A significantly decreased after RYGB by -7.54 (95% confidence interval [CI], -10.16 to -4.92) μg/dl at 12-23 months, vitamin E decreased after RYGB by -2.35 (95% CI, -3.65 to -1.05) μg/dl at ≥24 months, and ferritin by -54.93 (95% CI, -77.19 to -32.67] μg/L at ≥24 months after SG, compared with baseline, with moderate level of evidence. Significant decreases in micronutrient levels at certain follow-up intervals in studies with supplementation per guidelines need to be considered to establish a post-bariatric micronutrient monitoring schedule for timely detection and management of micronutrient deficiencies.

Abstract
Pediatric obesity is a multifaceted disease that can impact physical and mental health. It is a complex condition that interweaves biological, developmental, environmental, behavioral, and genetic factors. In most cases lifestyle and behavioral modification as well as medical treatment led to poor short-term weight reduction and long-term failure. Thus, bariatric surgery should be considered in adolescents with moderate to severe obesity who have previously participated in lifestyle interventions with unsuccessful outcomes. In particular, laparoscopic sleeve gastrectomy is considered the most commonly performed bariatric surgery worldwide. The procedure is safe and feasible. The efficacy of this weight loss surgical procedure has been demonstrated in pediatric age. Nevertheless, there are barriers at the patient, provider, and health system levels, to be removed. First and foremost, more efforts must be made to prevent decline in nutritional status that is frequent after bariatric surgery, and to avoid inadequate weight loss and weight regain, ensuring successful long-term treatment and allowing healthy growth. In this narrative review, we considered the rationale behind surgical treatment options, outcomes, and clinical indications in adolescents with severe obesity, focusing on LSG, nutritional management, and resolution of metabolic comorbidities.

Abstract
Beriberi is a nutritional complication of gastric surgery, caused by deficiency of vitamin B1, or thiamine. Thiamine deficiency leads to impaired glucose metabolism, decreased delivery of oxygen by red blood cells, cardiac dysfunction, failure of neurotransmission, and neuronal death. This review describes the history and pathophysiology of beriberi as well as the relationship between beriberi and nutritional deficiencies after gastric surgery. A literature review of the history and pathophysiology of beriberi and the risk factors for thiamine deficiency, particularly after gastric resection or bariatric surgery, was performed. Recommendations for nutritional follow-up post gastric surgery are based on current national guidelines. Patients may have subclinical thiamine deficiency after upper gastrointestinal surgery, and thus beriberi may be precipitated by acute illness such as sepsis or poor dietary intake. This may occur very soon or many years after gastrectomy or bariatric surgery, even in apparently well-nourished patients. Prompt recognition and administration of supplemental thiamine can decrease morbidity and mortality in patients with beriberi. Dietary education post surgery and long-term follow-up to determine nutritional status, including vitamin and mineral assessment, is recommended for patients who undergo gastric surgery.

Abstract
BACKGROUND Many patients complain of nutritional symptoms after bariatric surgery (BS), including hair loss, cramps, and paresthesia, but their link with biological alterations has been poorly studied. OBJECTIVES To assess in a large cohort of subjects the relationship between nutritional symptoms and biological deficits both in the short term (ST ≤ 1 year) and long term (LT ≥ 3 years) after the 2 most common procedures, Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG). METHODS Nutritional symptoms and biological parameters (including vitamins, minerals, and protein parameters) were prospectively recorded. All subjects with complete clinical and biological assessments from 2011 to 2018 were included. RESULTS After BS, 555 subjects were studied in the ST (50% RYGB) and 494 in the LT (79% RYGB); multivitamin intake was 97% and 78%, respectively. The proportion of patients with hair loss decreased from 65 (ST) to 35% (LT) (p < 0.001). In contrast, cramps increase from 7 to 32% and paresthesia from 11 to 18% (p < 0.001). No significant difference was found between SG and RYGB. In subjects with hair loss, blood parameters of protein and iron metabolism were significantly lower than in subjects without hair loss, both in the ST and LT. In contrast, neither zinc nor group B vitamin levels were significantly different. None of the nutritional parameters tested was clearly associated with cramps and paresthesia. CONCLUSION After BS, the most frequent nutritional symptom is hair loss, essentially linked to iron and protein deficiencies. The causes of other nutritional symptoms are less clear and probably more heterogeneous.

Abstract
Nutritional care after bariatric surgery is an issue of major importance, especially insofar as risk of deficiency has been extensively described in the literature. Subsequent to the deliberations carried out by a multidisciplinary working group, we are proposing a series of recommendations elaborated using the Delphi-HAS (official French health authority) method, which facilitates the drawing up of best practice and consensus recommendations based on the data of the literature and on expert opinion. The recommendations in this paper pertain to dietary management and physical activity, multivitamin and trace element supplementation and the prevention and treatment of specific deficiencies in vitamins B1, B9, B12, D and calcium, iron, zinc, vitamins A, E and K, dumping syndrome and reactive hypoglycemia.

Abstract
Obesity is a major factor in the worldwide rise in the prevalence of type 2 diabetes mellitus. The obesity "epidemic" will require novel, effective interventions to permit both the prevention and treatment of diabetes caused by obesity. Laparoscopic vertical sleeve gastrectomy is a newer bariatric surgical procedure with a lower risk of complications (compared to Roux-en-Y gastric bypass surgery). Based in part on restriction of daily caloric intake, sleeve gastrectomy has a major role in inducing significant weight loss and weight loss is maintained for at least 10 years. Prior studies have supported the utility of the vertical sleeve gastrectomy for the treatment and management of subgroups of individuals with diabetes mellitus. There are reports of 11% to 76.9% of obese individuals discontinuing use of diabetic medications in studies lasting up to 8 years after vertical sleeve gastrectomy. Major ongoing issues include the preoperative determination of the suitability of diabetic patients to undergo this bariatric surgical procedure. Understanding how this surgical procedure is performed and the resulting anatomy is important when vertical sleeve gastrectomy is being considered as a treatment option for diabetes. In the postoperative periods, specific macronutrient goals and micronutrient supplements are important for successful and safer clinical results. An understanding of immediate- and long term- potential complications is important for reducing the potential risks of vertical sleeve gastrectomy. This includes the recognition and treatment of postoperative nutritional deficiencies and disorders. Vertical sleeve gastrectomy is a component of a long term, organized program directed at treating diabetes related to obesity. This approach may result in improved patient outcomes when vertical sleeve gastrectomy is performed to treat type 2 diabetes in obese individuals.

Abstract
BACKGROUND Patients undergoing metabolic and bariatric surgery are prone to developing micronutrient deficiencies, necessitating life-long nutritional supplementation and monitoring. Historically, these deficiencies were thought to be driven by postsurgical changes in absorption. Recent data, though, have demonstrated that obesity alone is also associated with micronutrient deficiencies. Thiamine deficiency, in particular, can lead to permanent neurologic deficits. OBJECTIVE Identify thiamine deficiency prevalence within the preoperative metabolic and bariatric surgery patient population. SETTING Single institution academic medical center. METHODS A retrospective review of deidentified data was examined that included whole blood thiamine measured from consecutive patients from April 2018 to June 2019 (n = 346). Cohort characteristics were assessed including age, operation, preoperative weight, and race/ethnicity. The majority of the cohort were women (83%) with an average age of 44.9 years. Racial representation included White/Caucasian (73%) and Black (21%), while operations included Roux-en-Y gastric bypass (58%), sleeve gastrectomy (31%), and revisions (10%). RESULTS Thiamine concentration was normally distributed with a mean of 144 nM. Overall, 3.5% of patients had thiamine concentrations below the lower limit of normal of <70 nM, while 35 additional patients (14%) were at risk for thiamine deficiency with concentrations <100 nM. On the average, these patients were of similar age and were all undergoing primary procedures (50% gastric bypass, 50% sleeve gastrectomy). Regression methods demonstrated that patients with thiamine deficiency tended to be females with higher body mass index, even after controlling for sex, height, and preoperative weight. After covariate adjustment, male sex and increasing height were both associated with higher thiamine concentration. CONCLUSION Previously quoted rates of thiamine deficiency in the preoperative patient are variable, but we describe a significant number of patients with, or at risk of, thiamine deficiency. Male sex and increasing height are likely associated with increased skeletal muscle mass, which is enriched with thiamine. Routine thiamine measurement, either preoperatively or at the time of surgery, is warranted given its limited stores within the body and potential catastrophic complications associated with acute or chronic deficiency.

Abstract
Wernicke’s encephalopathy (WE) is an acute neurological disorder resulting from thiamine deficiency, commonly found in alcohol use disorder (AUD) patients. Liver transplantation (LT) could represent a risk factor for the onset of WE in AUD patients, due to the onset of chronic depletion of thiamine in this population and the high metabolic demand of surgery and the postoperative period. However, few data are available about the risk of the onset of WE in AUD patients after LT. Here we report three cases of AUD patients who developed WE with confusion and delirium after LT. Prompt parenteral administration of thiamine led to a rapid improvement of the clinical condition and a complete remission of neurological symptoms after 3–4 days. In addition, a search of the available English literature was conducted in order to perform a review of the possible association between the onset of WE and LT in AUD patients. A prophylactic treatment regimen based on the administration of thiamine could be suggested in AUD patients before and after LT. Further studies are needed to determine the optimal regimen of thiamine in the prevention of WE in this setting.

Abstract
Introduction Bariatric surgery has a significant impact on dietary intake, weight loss, patient’s metabolism and also on defaecation stereotypes. Aim To investigate changes in bowel habits of morbidly obese patients after laparoscopic sleeve gastrectomy (LSG). Material and methods This was a prospective clinical cohort study conducted to assess changes in bowel habits after LSG in a single institution. Results In total, 124 patients were enrolled in the study (age 47.1 ±11.2 years, body mass index (BMI) 44.3 ±6.8 kg/m2). The mean weight loss 6 months after LSG was 29.1 ±11.1 kg; percentage excess weight loss was 56.2 ±20.4%. Before surgery, 35.5% of patients had constipation and 6.5% of patients had faecal incontinence (FI). No correlation was found between rising level of BMI and constipation or incontinence prevalence/severity. Data analysis has not confirmed increased prevalence/severity of postoperative constipation or incontinence 6 months after LSG. Out of the group of patients with preoperative constipation, clinically relevant improvement was noted in 45.5% of patients after the surgery. Among patients without constipation before surgery, impairment was noted in 21.2% of patients. Out of the group of patients with preoperative incontinence, improvement was found in 37.5% of patients; none of these patients reported clinically relevant impairment of incontinence symptoms. Conclusions The present study has not revealed increased prevalence/severity of postoperative constipation or anal incontinence 6 months after LSG. Our findings suggest that weight loss in patients after LSG might be associated with an improvement of constipation symptoms of individual patients.

Abstract
In order to develop evidence-based recommendations and expert consensus for nutrition management of patients undergoing bariatric surgery and postoperative follow-up, we conducted a systematic literature search using PRISMA methodology plus critical appraisal following the SIGN and AGREE-II procedures. The results were discussed among all members of the GARIN group, and all members answered a Likert scale questionnaire to assess the degree of support for every recommendation. Patients undergoing bariatric surgery should be screened preoperatively for some micronutrient deficiencies and treated accordingly. A VLCD (Very Low-Calorie Diet) should be used for 4-8 weeks prior to surgery. Postoperatively, a liquid diet should be maintained for a month, followed by a semi-solid diet also for one month. Protein requirements (1-1.5 g/kg) should be estimated using adjusted weight. Systematic use of specific multivitamin supplements is encouraged. Calcium citrate and vitamin D supplements should be used at higher doses than are currently recommended. The use of proton-pump inhibitors should be individualised, and vitamin B12 and iron should be supplemented in case of deficit. All patients, especially pregnant women, teenagers, and elderly patients require a multidisciplinary approach and specialised follow-up. These recommendations and suggestions regarding nutrition management when undergoing bariatric surgery and postoperative follow-up have direct clinical applicability.

Abstract
Objective: Postoperative delirium is a common complication after gastrointestinal surgery that is associated with adverse outcomes. Thiamine is an essential cofactor for the glycolysis, oxidative metabolism, production of neurotransmitters in the crebs cycle. In this study, efficacy of thiamine was assessed as a preventive strategy of delirium in patients undergoing gastrointestinal surgery. Methods: In this randomized clinical trial, 96 adult patients admitted to the intensive care unit (ICU) following gastrointestinal surgery were included. Patients were allocated to receive either 200 mg intravenous thiamine daily or an equal volume of 0.9% saline for 3 days. Delirium was evaluated twice daily based on the confusion assessment method-ICU. The incidence of postoperative delirium was considered as the primary outcome, and total analgesic use and ventilation days has been defined as secondary outcomes of the study. Findings: The incidence rate of delirium was significantly lower in the thiamine group than the placebo group on the first day (8.3% vs. 25%; Odds ratio: 0.27 [95% confidence interval (CI): 0.08–0.92]; P= 0.026) and on the second day (4.2% vs. 20.8%; or: 0.16 [95% CI: 0.03–0.81]; P= 0.014). No adverse effect related to thiamine was detected during the study course. Conclusion: Study results suggest that thiamine is a safe option for the prevention of postoperative delirium in patients after gastrointestinal surgery.

Abstract
Sleeve gastrectomy is a restrictive-type weight loss surgery that can result in nutritional deficiencies, such as vitamin B1 (thiamine) deficiency. Although Wernicke’s encephalopathy is a known complication following bariatric surgery, bilateral sensorineural hearing loss is a rare presenting symptom of this condition. We present a case of a patient two months postoperative following a sleeve gastrectomy whose chief complaint was hearing loss. While initial laboratory evaluation of her complaint showed elevated inflammatory markers, prompting an autoimmune workup, ultimately the diagnosis of Wernicke’s encephalopathy was confirmed by a low thiamine level and magnetic resonance imaging findings. A correction of the patient’s thiamine deficiency led to an improvement of her symptoms.

Abstract
Obesity is associated with reduced gut microbial diversity and a high rate of micronutrient deficiency. Bariatric surgery, the therapy of choice for severe obesity, produces sustained weight loss and improvements in obesity-related comorbidities. Also, it significantly alters the gut microbiota (GM) composition and function, which might have an important impact on the micronutrient status as GM is able to synthesize certain vitamins, such as riboflavin, folate, B12, or vitamin K2. However, recent data have reported that GM is not fully restored after bariatric surgery; therefore, manipulation of GM through probiotics represents a promising therapeutic approach in bariatric patients. In this review, we discuss the latest evidence concerning the relationship between obesity, GM and micronutrients, the impact of bariatric surgery on GM in relation with micronutrients equilibrium, and the importance of the probiotics' supplementation in obese patients submitted to surgical treatment.

Hanachi M, Dicembre M, Rives-Lange C, Ropers J, Bemer P, Zazzo JF, Poupon J, Dauvergne A, Melchior JC. Micronutrients Deficiencies in 374 Severely Malnourished Anorexia Nervosa Inpatients. Nutrients 2019; 11:nu11040792. [PMID: 30959831 PMCID: PMC6520973 DOI: 10.3390/nu11040792] [Citation(s) in RCA: 36] [Impact Index Per Article: 7.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2019] [Revised: 03/27/2019] [Accepted: 04/01/2019] [Indexed: 12/18/2022] Open
Abstract
Introduction: Anorexia nervosa (AN) is a complex psychiatric disorder, which can lead to specific somatic complications. Undernutrition is a major diagnostic criteria of AN which can be associated with several micronutrients deficiencies. Objectives: This study aimed to determinate the prevalence of micronutrients deficiencies and to compare the differences between the two subtypes of AN (restricting type (AN-R) and binge-eating/purging type (AN-BP)). Methods: We report a large retrospective, monocentric study of patients hospitalized in a highly specialized nutrition unit between January 2011 and August 2017 for severe malnutrition treatment in the context of anorexia nervosa. Results: Three hundred and seventy-four patients (360 (96%) women, 14 (4%) men), age: 31.3 ± 12.9 years, Body Mass Index (BMI): 12.5 ± 1.7 kg/m2 were included; 253 (68%) patients had AN-R subtype while, 121 (32%) had AN-BP. Zinc had the highest deficiency prevalence 64.3%, followed by vitamin D (54.2%), copper (37.1%), selenium (20.5%), vitamin B1 (15%), vitamin B12 (4.7%), and vitamin B9 (8.9%). Patients with AN-BP type had longer disease duration, were older, and had a lower left ventricular ejection fraction (LVEF) (p < 0.001, p = 0.029, p = 0.009), when compared with AN-R type, patients who instead, had significantly higher Alanine Aminotransferase (ALT) and Brain Natriuretic Peptide (BNP) levels (p < 0.001, p < 0.021). In the AN-BP subgroup, as compared to AN-R, lower selenium (p < 0.001) and vitamin B12 plasma concentration (p < 0.036) were observed, whereas lower copper plasma concentration was observed in patients with AN-R type (p < 0.022). No significant differences were observed for zinc, vitamin B9, vitamin D, and vitamin B1 concentrations between the two types of AN patients. Conclusion: Severely malnourished AN patients have many micronutrient deficiencies. Differences between AN subtypes are identified. Micronutrients status of AN patients should be monitored and supplemented to prevent deficiencies related complications and to improve nutritional status. Prospective studies are needed to explore the symptoms and consequences of each deficiency, which can aggravate the prognosis during recovery.
