RESUMO

INTRODUCTION: Obesity is a major global health problem associated with comorbidities such as diabetes, cardiovascular disease, and cancer. Bariatric surgery is recognized to be the most effective weight loss intervention, but it is highly invasive and costly and can have serious side effects. Intragastric balloon (IGB) placement by endoscopy and hypocaloric diets are among a number of techniques that have been used in patients unsuitable for, or unwilling to undergo, obesity surgery. In this study, we compared the efficacy, safety, and cost-effectiveness of the hypocaloric OPTIFAST program (OPT) with endoscopic IGB placement for weight loss. METHODS: In this retrospective observational cohort propensity score-weighted comparison (performed May 2014 to December 2020), participants with a BMI of 30-55 kg/m2, aged 18-70 years, were randomized to OPT or IGB for 26 weeks, followed by a weight maintenance phase. Patients were matched according to age, gender, and BMI. The study outcomes were percentage excess body weight lost, total body weight lost (TBWL), and percentage TBWL (%TBWL). RESULTS: A total of 148 participants (75% of those randomized; 74 OPT, 74 IGB) made up the ITT population. Mean age was 44.1 ± 10.4 years, and the patients were predominantly female (77%). Baseline BMI was 44.1 ± 10.4 kg/m2. At 26 weeks, %TBWL in the OPT group was 19.6 ± 6.8% versus 11.9 ± 6.7% for IGB (p < 0.001). At 52 weeks, %TBWL for OPT was 18.2 ± 9.0% versus 12.0 ± 6.6% for IGB (p < 0.001). The OPT cohort also experienced significantly fewer adverse events compared with the IGB group. CONCLUSION: IGB placement and OPT induce clinically meaningful weight loss. However, OPT appears to induce clinically superior weight loss and has economic advantages through lower rates of complications and adverse events.

RESUMO

Iron deficiency is the primary cause of anaemia worldwide and is particularly common among children and adolescents. Intravenous (IV) iron therapy is recommended for paediatric patients with certain comorbidities or if oral iron treatment has been unsuccessful. IV ferric carboxymaltose (FCM) has recently been approved by the US Food and Drug Administration for use in children aged > 1 year. This narrative review provides an overview of the available publications on the efficacy and safety of IV FCM in children and adolescents. A literature search using PubMed and Embase yielded 153 publications; 33 contained clinical data or reports on clinical experience relating to IV FCM in subjects < 18 years of age and were included in the review. No prospective, randomised controlled studies on the topic were found. Most publications were retrospective studies or case reports and included patients with various underlying conditions or patients with inflammatory bowel disease. Efficacy data were included in 27/33 publications and improvements in anaemia, and/or iron status parameters were reported in 26 of them. Safety data were included in 25/33 publications and were in line with the adverse events described in the prescribing information. CONCLUSION: The available publications indicate that IV FCM, a nanomedicine with a unique and distinctive therapeutic profile, is an effective and generally well-tolerated treatment for iron deficiency or iron deficiency anaemia in children and adolescents. Despite the wealth of retrospective evidence, prospective, randomised controlled trials in the paediatric setting are still necessary. WHAT IS KNOWN: • Iron deficiency and iron deficiency anaemia are usually managed using oral iron therapy, but intravenous iron therapy is recommended for certain paediatric patients. • Intravenous ferric carboxymaltose (FCM) has recently been approved in the US for use in children aged > 1 year. WHAT IS NEW: • Despite evidence that FCM is effective and generally well tolerated in children and adolescents, so far, only retrospective studies, non-randomised uncontrolled prospective studies, or case reports have been published in full. • There is a strong need for prospective, randomised controlled trials on FCM in the paediatric setting.

RESUMO

INTRODUCTION: Both laparoscopic Roux-en-Y gastric bypass (RYGB) and duodenojejunal bypass liner (DJBL) have been shown to induce weight loss and dramatically ameliorate type 2 diabetes mellitus (T2DM). Since DJBL implantation causes nutrients to pass through the duodenum without contact with the digestive juices and the duodenal mucosa, its mechanisms have been suggested to mimic those of RYGB. This study aimed to compare the outcomes of these two bariatric procedures in terms of glycemic control and BMI in patients with obesity and T2DM. RESEARCH DESIGN AND METHODS: A retrospective observational cohort propensity score-weighted comparison of laparoscopic Roux-en-Y gastric bypass (RYGB) vs duodenojejunal bypass liner (DJBL) was conducted in patients with obesity and T2DM undergoing either procedure from 05/2014 to 12/2017. Propensity scores were weighted for body weight, body mass index (BMI), and glycated hemoglobin A1c (HbA1c). The primary outcome was comparative improvement of HbA1c. Secondary comparative effectiveness outcomes were decrease of body weight and BMI. RESULTS: Forty-six patients were included: 21 (10 male, 11 female; mean age 50.6 ± 11.7 years) underwent RYGB, while DJBL was implanted in 25 (10 male, 15 female; 52.5 ± 9.5 years). After twelve months, mean ΔBMI was 11.54 ± 4.47 kg/m2 for RYGB vs. 6.23 ± 2.36 kg/m2 for DJBL (p < 0.05). Mean total weight loss was 27.93 ± 8.57% for RYGB vs. 15.04 ± 5.73% for DJBL (p < 0.05). Glycemic control after one year improved significantly in both groups but did not differ significantly. CONCLUSION: RYGB and DJBL seem to be associated with similar remission rates of hyperglycemia after one year. However, RYGB induces more significant weight loss than DJBL.

RESUMO

BACKGROUND: Biotin, a water-soluble B vitamin, has demonstrable anti-inflammatory properties. A biotin-deficient diet induced a colitis-like phenotype in mice, alleviable by biotin substitution. Mice with dextran sulfate sodium (DSS)-induced colitis showed biotin deficiency and diminished levels of sodium-dependent multivitamin transporter, a protein involved in biotin absorption. Biotin substitution induced remission by reducing activation of NF-κB, a transcription factor involved in intestinal permeability and inflammatory bowel disease (IBD). We investigated for the first time a possible clinical role of biotin status in IBD. METHODS: In a comparative, retrospective, cross-sectional study, serum samples of 138 patients with IBD (67 female; 72 Crohn's disease (CD), 66 ulcerative colitis (UC)) aged 18-65 years and with a mean age (±SD) of 42.5 ± 14.3 years as well as 80 healthy blood donors (40 female; 40.0 ± 10.0 years; range 20-60 years) were analyzed. Inflammation was defined as hsCRP ≥5 mg/L, and to determine biotin status, serum 3-hydroxyisovaleryl carnitine (3HIVc) levels were measured by LC-MS/MS. RESULTS: A total of 138 patients with IBD (67f; 72CD/66 UC; 42.5 ± 14.3 years) were enrolled: 83/138 had inflammation. Mean serum 3HIVc levels were significantly higher in IBD patients but unaffected by inflammation. Biotin deficiency (95th percentile of controls: >30 nmol/L 3HIVc) was significantly more common in IBD patients versus controls. CONCLUSION: High serum 3HIVc levels and biotin deficiency were associated with IBD but not inflammatory activity or disease type. Our findings suggest biotin may play a role as cause or effect in IBD pathogenesis. Routine assessment and supplementation of biotin may ameliorate IBD and support intestinal integrity.

RESUMO

Background: Osteopontin (OPN) is a glycosylated phosphoprotein found in human tissues and body fluids. OPN in breast milk is thought to play a major role in growth and immune system development in early infancy. Here, we investigated maternal factors that may affect concentrations of OPN in breast milk, and the possible associated consequences for the health of neonates. Methods: General characteristics, health status, dietary patterns, and anthropometric measurements of 85 mothers and their babies were recorded antenatally and during postnatal follow-up. Results: The mean concentration of OPN in breast milk was 137.1 ± 56.8 mg/L. Maternal factors including smoking, BMI, birth route, pregnancy weight gain, and energy intake during lactation were associated with OPN levels (p < 0.05). Significant correlations were determined between body weight, length, and head circumference, respectively, and OPN levels after one (r = 0.442, p = < 0.001; r = -0.284, p = < 0.001; r = -0.392, p = < 0.001) and three months (r = 0.501, p = < 0.001; r = -0.450, p = < 0.001; r = -0.498, p = < 0.001) of lactation. A negative relation between fever-related infant hospitalizations from 0-3 months and breast milk OPN levels (r = -0.599, p < 0.001) was identified. Conclusions: OPN concentrations in breast milk differ depending on maternal factors, and these differences can affect the growth and immune system functions of infants. OPN supplementation in infant formula feed may have benefits and should be further investigated.

RESUMO

BACKGROUND: In the absence of a feasible noninvasive gold standard, iron deficiency (ID) anemia (IDA) is best measured using multiple indicators. However, the choice of an appropriate single iron biomarker for ID screening continues to be debated. Low hemoglobin density (LHD%) from Coulter counters has been suggested as a useful tool to detect ID. This study investigated the reliability of LHD% for the assessment of iron status in patients with inflammatory bowel disease (IBD) and IDA, anemia of chronic disease (ACD) or mixed anemia (MIX). METHODS: The study population consisted of 143 patients with IBD (aged 39.03±12.53 years, 61.5% female). Blood count, transferrin saturation, serum ferritin, and C-reactive protein were determined by routine assays. Patients with anemia were divided into 3 groups: IDA, ACD and MIX, according to specific criteria. Receiver operator characteristic (ROC) curves were constructed. RESULTS: ROC analysis for LHD% in the detection of ID yielded a cutoff value of 3.8%. In anemic patients, LHD% values did not differ statistically significantly between groups (IDA, ACD, MIX) and no significant difference in LHD% values was observed between patients with IDA and ID. CONCLUSIONS: These results demonstrate that LHD% is a reliable biomarker for the detection of iron deficiency in patients with IBD and anemia, regardless of whether inflammation is present. Our findings indicate that LHD% can provide added value in diagnosing iron deficiency.

RESUMO

Chronic intestinal failure (CIF) is a rare but feared complication of Crohn's disease. Depending on the remaining length of the small intestine, the affected intestinal segment, and the residual bowel function, CIF can result in a wide spectrum of symptoms, from single micronutrient malabsorption to complete intestinal failure. Management of CIF has improved significantly in recent years. Advances in home-based parenteral nutrition, in particular, have translated into increased survival and improved quality of life. Nevertheless, 60% of patients are permanently reliant on parenteral nutrition. Encouraging results with new drugs such as teduglutide have added a new dimension to CIF therapy. The outcomes of patients with CIF could be greatly improved by more effective prevention, understanding, and treatment. In complex cases, the care of patients with CIF requires a multidisciplinary approach involving not only physicians but also dietitians and nurses to provide optimal intestinal rehabilitation, nutritional support, and an improved quality of life. Here, we summarize current literature on CIF and short bowel syndrome, encompassing epidemiology, pathophysiology, and advances in surgical and medical management, and elucidate advances in the understanding and therapy of CIF-related complications such as catheter-related bloodstream infections and intestinal failure-associated liver disease.

RESUMO

INTRODUCTION: In patients with inflammatory bowel disease (IBD), iron deficiency anaemia (IDA) can impair quality of life and increase healthcare costs. Treatment options for IDA-associated IBD include oral iron and intravenous iron formulations (such as ferric carboxymaltose [FCM], ferric derisomaltose [FD, previously known as iron isomaltoside 1000], and iron sucrose [IS]). The present analysis compared the cost-effectiveness of FCM versus FD, IS, and oral iron sulfate in terms of additional cost per additional responder in the UK setting. METHODS: Cost-effectiveness was calculated for FCM versus FD, IS, and oral iron individually in terms of the additional cost per additional responder, defined as haemoglobin normalisation or an increase of ≥2 g/dL in haemoglobin levels, in a model developed in Microsoft Excel. Relative efficacy inputs were taken from a previously published network meta-analysis, since there is currently no single head-to-head trial evidence comparing all therapy options. Costs were calculated in 2020 pounds sterling (GBP) capturing the costs of iron preparations, healthcare professional time, and consumables. RESULTS: The analysis suggested that FCM may be the most effective intervention, with 81% of patients achieving a response. Response rates with FD, IS, and oral iron were 74%, 75%, and 69%, respectively. Total costs with FCM, FD, IS, and oral iron were GBP 296, GBP 312, GBP 503, and GBP 56, respectively. FCM was found to be more effective and less costly than both FD and IS, and therefore was considered dominant. Compared with oral iron, FCM was associated with an incremental cost-effectiveness ratio of GBP 2045 per additional responder. CONCLUSIONS: FCM is likely to be the least costly and most effective IV iron therapy in the UK setting. Compared with oral iron, healthcare payers must decide whether the superior treatment efficacy of FCM is worth the additional cost.

RESUMO

Iron deficiency (ID) is a common manifestation of inflammatory bowel disease (IBD), arising primarily due to chronic inflammation and/or blood loss. There is no gold standard for ID diagnosis, which is often complicated by concomitant inflammation. Zinc protoporphyrin (ZnPP) correlates with parameters of iron homeostasis and has been identified as a promising marker for ID, irrespective of inflammation. We investigated the diagnostic performance of ZnPP in ID, iron deficiency anemia, anemia of chronic disease and mixed anemia in a cross-sectional study in 130 patients with IBD. Different parameters were compared by receiver operator characteristic (ROC) analysis as detectors of iron-restricted erythropoiesis (IRE). IRE was detected in 91 patients (70.0%); fifty-nine (64.8%) had absolute ID and 23 (25.4%) functional ID. When inflammation was present, ZnPP was a more reliable sole biomarker of IRE than MCV, transferrin saturation (TSAT) or ferritin (AUC; 0.855 vs. 0.763, 0.834% and 0.772, respectively). The specificity of TSAT was significantly lower than ZnPP when inflammation was present (38% vs. 71%, respectively). We conclude that ZnPP is a reliable biomarker of functional ID in patients with IBD and more dependable than ferritin or TSAT, which are influenced by chronic inflammation. We propose that ZnPP may also have utility in patients with other chronic diseases.

RESUMO

Iron deficiency, with or without anemia, is the most frequent hematological manifestation in individuals with cancer, and is especially common in patients with colorectal cancer. Iron is a vital micronutrient that plays an essential role in many biological functions, in the context of which it has been found to be intimately linked to cancer biology. To date, however, whereas a large number of studies have comprehensively investigated and reviewed the effects of excess iron on cancer initiation and progression, potential interrelations of iron deficiency with cancer have been largely neglected and are not well-defined. Emerging evidence indicates that reduced iron intake and low systemic iron levels are associated with the pathogenesis of colorectal cancer, suggesting that optimal iron intake must be carefully balanced to avoid both iron deficiency and iron excess. Since iron is vital in the maintenance of immunological functions, insufficient iron availability may enhance oncogenicity by impairing immunosurveillance for neoplastic changes and potentially altering the tumor immune microenvironment. Data from clinical studies support these concepts, showing that iron deficiency is associated with inferior outcomes and reduced response to therapy in patients with colorectal cancer. Here, we elucidate cancer-related effects of iron deficiency, examine preclinical and clinical evidence of its role in tumorigenesis, cancer progression and treatment response. and highlight the importance of adequate iron supplementation to limit these outcomes.

RESUMO

INTRODUCTION: Iron deficiency anemia (IDA) is a common complication of inflammatory bowel disease (IBD) and can result in reduced quality of life and increased healthcare costs. IDA is treated with iron supplementation, either with oral iron therapy (OI) or intravenous iron formulations, including ferric carboxymaltose (FCM), iron isomaltoside 1000 (IIM), and iron sucrose (IS). This analysis compared the cost-effectiveness of FCM versus IIM, IS, and OI in terms of additional cost per additional responder in Switzerland. METHODS: A health economic model was developed to assess the additional cost per additional responder, defined as normalization or an increase of at least 2 g/dL in hemoglobin levels, for FCM versus IIM, IS, and OI. To date, no single head-to-head trial comparing all therapies is available, and therefore relative efficacy data were taken from a published network meta-analysis. Costs of treatment were calculated in 2020 Swiss francs (CHF) using a microcosting approach, and included the costs of iron, healthcare professional time, and consumables. Costs are also presented in euros (EUR) based on an exchange rate of CHF 1 = EUR 0.94. RESULTS: Response rates with FCM, IIM, IS, and OI were 81%, 74%, 75%, and 69%, respectively, with FCM projected to be the most effective treatment. FCM was associated with cost savings of CHF 24 (EUR 23) versus IIM and of CHF 147 (EUR 138) versus IS, and increased costs by CHF 345 (EUR 324) versus OI. Therefore FCM was considered dominant versus both IIM and IS, improving clinical outcomes with cost savings. FCM was associated with an incremental cost-effectiveness ratio of CHF 2970 (EUR 2792) per additional responder versus OI. CONCLUSIONS: FCM was projected to be the most cost-effective intravenous iron therapy in Switzerland, increasing the number of responders and leading to cost savings for healthcare payers.

RESUMO

Background Obesity and obesity-related diseases are one of the common health problems worldwide and have also been proposed to be important predictors of blood pressure and cardiovascular disease risk. The aim of our study is to determine the utility of different anthropometric measurements (body mass index [BMI], skinfold thickness [SFT], waist circumference [WC], mid-upper arm circumference [MUAC], arm circumference-height ratio [AHtR], and waist circumference-height ratio [WHtR]) as markers of hypertension (HT) risk in adolescents. Methods In this cross-sectional study, 544 participants aged between 12 and 13 years were included. Anthropometric measurements and blood pressure of participants were measured. The association of different anthropometric measurements with blood pressure was evaluated. Results The frequency of both elevated blood pressure and HT was 30.2%. Biceps, triceps, and suprailiac SFT have an impact on HT in girls but only suprailiac SFT in boys. WC measurements above the 85th percentile were strongly correlated with HT conditions, and this relationship was stronger in boys than in girls (3.3 vs. 2.6 fold). MUAC, WHtR, and AHtR measurements also have strong correlation with HT in boys but only WHtR has a poor relation in girls. In boys and girls with obesity, there was a positive association between obesity and blood pressures. Conclusions Not only age-related BMI z scores but also a number of other anthropometric measurements, such as WC, SFT, MUAC, WHtR, and AHtR, could have an influence on high blood pressure. The influence changes with gender during adolescence.

RESUMO

Evidence gained from recent studies has generated increasing interest in the role of vitamin D in extraskeletal functions such as inflammation and immunoregulation. Although vitamin D deficiency has been implicated in the pathophysiology of inflammatory diseases including inflammatory bowel disease (IBD), evidence as to whether vitamin D supplementation may cure or prevent chronic disease is inconsistent. Since 25OH-vitamin D (25OHD) has been suggested to be an acute-phase protein, its utility as a vitamin D status marker is therefore questionable. In this study, possible interactions of vitamin D and inflammation were studied in 188 patients with IBD, with high-sensitivity C-reactive protein (hsCRP) levels ≥ 5 mg/dL and/or fecal calprotectin ≥ 250 µg/g defined as biochemical evidence of inflammatory activity. Levels of 25OHD and vitamin D-binding protein (VDBP) were determined by ELISA, and 1,25-dihydroxyvitamin D (1,25OHD) and dihydroxycholecalciferol (24,25OHD) by LC-MS/MS. Free and bioavailable vitamin D levels were calculated with the validated formula of Bikle. Serum 1,25OH2D and vitamin D binding protein (VDBP) levels were shown to differ between the inflammatory and noninflammatory groups: patients with inflammatory disease activity had significantly higher serum concentrations of 1,25OH2D (35.0 (16.4-67.3) vs. 18.5 (1.2-51.0) pg/mL, p < 0.001) and VDBP (351.2 (252.2-530.6) vs. 330.8 (183.5-560.3) mg/dL, p < 0.05) than patients without active inflammation. Serum 24,25OH2D levels were negatively correlated with erythrocyte sedimentation rate (ESR) (-0.155, p = 0.049) while concentrations of serum 1,25OH2D correlated positively with hsCRP (0.157, p = 0.036). Correlations with serum VDBP levels were found for ESR (0.150, p = 0.049), transferrin (0.160, p = 0.037) and hsCRP (0.261, p < 0.001). Levels of serum free and bioavailable 25OHD showed a negative correlation with ESR (-0.165, p = 0.031, -0.205, p < 0.001, respectively) and hsCRP (-0.164, p = 0.032, -0.208, p < 0.001 respectively), and a moderate negative correlation with fecal calprotectin (-0.377, p = 0.028, -0.409, p < 0.016, respectively). Serum total 25OHD concentration was the only vitamin D parameter found to have no specific correlation with any of the inflammatory markers. According to these results, the traditional parameter, total 25OHD, still appears to be the best marker of vitamin D status in patients with inflammatory bowel disease regardless of the presence of inflammation.

RESUMO

BACKGROUND AND AIMS: Anaemia is common in patients with inflammatory bowel disease [IBD], its two main aetiologies being iron deficiency anaemia [IDA] and anaemia of chronic inflammation [ACI]. Impaired intestinal iron absorption due to inflammatory cytokines is thought to play a role in ACI. We undertook for the first time a controlled prospective study investigating effects of differing underlying diseases, disease locations, and types of iron deficiency or anaemia on oral iron absorption in adult IBD patients with and without inflammation. METHODS: This study was a comparative, single-centred open clinical trial in adults with IBD [n = 73] and healthy controls [n = 22]. Baseline parameters included blood count, iron status [ferritin, transferrin, transferrin saturation, soluble transferrin receptor, hepcidin, serum iron], high-sensitivity C-reactive protein [hsCRP] and interleukin-6. Iron absorption was tested using one oral, enteric-coated capsule containing 567.7 mg iron[II]-glycine-sulphate complex. Serum iron was determined 60/90/120/180/240 min after ingestion. RESULTS: Iron absorption capacity was shown to be influenced by inflammation and anaemia or iron deficiency [ID] type but not by underlying disease type or localisation. The ACI group showed a significantly lower iron absorption capacity than all others. Whereas hsCRP levels [-0.387, p < 0.001], IL-6 [-0.331, p = 0.006], ferritin [-0.531, p < 0.001], and serum hepcidin [-0.353, p = 0.003] correlated negatively with serum iron change at 2 h, transferrin showed a positive correlation at the same time point [0.379, p < 0.001]. CONCLUSIONS: Underlying disease type and localisation appear to have little effect on iron absorption capacity, whereas lack of response to oral iron correlates well with serum markers of inflammation. Iron absorption capacity is thus significantly reduced in the presence of inflammation.

RESUMO

BACKGROUND: Obesity is an independent risk factor for cardiovascular disease and diabetes weight reduction not only reduces the risk for these diseases but leads to an alteration of the circulating adipokine levels. The aim of our study was to evaluate the effect of weight loss and lifestyle changes implemented in the form of the interdisciplinary weight management programme Optifast52® on cardiovascular and diabetic risk factors and on key adipokines. METHODS: 72 morbidly obese patients were included in the programme, which consisted of a very low-calorie diet followed by incremental food introduction and dietary stabilisation, accompanied by medical surveillance, physical activity, dietary counselling and psychological support. At baseline, and after 14, 26 and 49 weeks, risk factor profiles and adipokine levels were evaluated. RESULTS: 43 patients completed the programme with an average weight reduction of about 20%. Significant improvement was observed in the lipid and diabetic laboratory panels of all patients. In addition, adiponectin levels increased significantly (7.79 vs. 12.38µg/ml, p<0.001), while leptin levels decreased (7.29 vs 3.09ng/ml, p<0.001) during the course of the programme. CONCLUSION: In this study, Optifast52®, a multidisciplinary programme focusing on diet and lifestyle changes, was found not only to affect a decrease in parameters associated with diabetes and cardiovascular disease, but also to ameliorate in part the obesity-related imbalance of pro- and anti-inflammatory adipokines.

RESUMO

BACKGROUND: Hepcidin has been shown to be inversely associated with iron absorption and the expression of iron transport proteins in healthy females and patients with iron deficiency. Data describing the relationship between hepcidin expression and iron absorption in patients with inflammatory bowel disease (IBD) are lacking. The objective of this study was to assess the relationship between serum concentrations of hepcidin and iron absorption in patients with IBD and iron deficiency by means of an oral iron absorption test. METHODS: This study was conducted as a comparative, single-centered, open clinical trial. After overnight fasting, an oral iron absorption test was performed, serum iron concentrations were measured 60, 90, 120, 180, and 240 minutes. Changes in iron levels between baseline and the 2-hour timepoint were calculated and recorded. RESULTS: Both ferritin and serum hepcidin levels are found to be good predictors of iron malabsorption, with sensitivity and specificity both at levels > 95%. When the two markers are compared, in our analysis, serum hepcidin levels (AUC: 0.817) tended to predict iron malabsorption slightly better than serum ferritin (AUC: 0.788). CONCLUSIONS: The evidence from our study suggests that serum hepcidin levels are a promising predictor of absorptive capacity in patients treated with oral iron compounds.
