- Proposal of an obesity classification based on weight history: an official document by the Brazilian Society of Endocrinology and Metabolism (SBEM) and the Brazilian Society for the Study of Obesity and Metabolic Syndrome (ABESO)(2022) HALPERN, Bruno; MANCINI, Marcio C.; MELO, Maria Edna de; LAMOUNIER, Rodrigo N.; MOREIRA, Rodrigo O.; CARRA, Mario K.; KYLE, Theodore K.; CERCATO, Cintia; BOGUSZEWSKI, Cesar LuizObesity is a chronic disease associated with impaired physical and mental health. A widespread view in the treatment of obesity is that the goal is to normalize the individual's body mass index (BMI). However, a modest weight loss (usually above 5%) is already associated with clinical improvement, while weight losses of 10%-15% bring even further benefits, independent from the final BMI. The percentage of weight reduction is accepted as a treatment goal since a greater decrease in weight is frequently difficult to achieve due to metabolic adaptation along with environmental and lifestyle factors. In this document, the Brazilian Society of Endocrinology and Metabolism (SBEM) and the Brazilian Society for the Study of Obesity and Metabolic Syndrome (ABESO) propose a new obesity classification based on the maximum weight attained in life (MWAL). In this classification, individuals losing a specific proportion of weight are classified as having ""reduced"" or ""controlled"" obesity. This simple classification - which is not intended to replace others but to serve as an adjuvant tool - could help disseminate the concept of clinical benefits derived from modest weight loss, allowing individuals with obesity and their health care professionals to focus on strategies for weight maintenance instead of further weight reduction. In future studies, this proposed classification can also be an important tool to evaluate possible differences in therapeutic outcomes between individuals with similar BMIs but different weight trajectories.
- Tratamento de curto prazo com liraglutide no reganho de peso após cirurgia bariátrica(2013) PAJECKI, Denis; HALPERN, Alfredo; CERCATO, Cintia; MANCINI, Marcio; CLEVA, Roberto de; SANTO, Marco AurélioOBJECTIVE: To evaluate the results of the use of liraglutide in a group of patients undergoing surgical treatment of morbid obesity with unsatisfactory weight loss or regain of more than 15% of minimum reached weight. METHODS: The authors conducted a retrospective analysis of 15 operated patients who had excess weight loss <50% after two years of follow-up or regained weight more than 15% of the minimum reached weight. We included only patients who had the expected ""surgical anatomy"", assessed by contrast radiography and endoscopy. Mean age was 47.2 ± 12.5 years, and patients received liraglutide at doses from 1.2 to 3.0 mg/day for eight to 28 weeks follow-up. RESULTS: Surgical treatment induced a weight loss of 34.1 ± 16.5 kg. The average weight regain after 5.3 ± 3.3 years was 14.2 ± 12.1 Kg. The average weight was significantly reduced after treatment with liraglutide (100.9 ± 18.3 kg. vs Kg 93.5 ± 17.4, p <0.0001). Six patients had nausea and two discontinued therapy due to the cost of medication. CONCLUSION: medical treatment directed to the control of satiety using liraglutide may be an alternative treatment of patients with poor weight loss or weight regain after surgery when no technical problem has been identified.
- Lack of mutations in the leptin receptor gene in severely obese children(2012) DIAS, Natasha Favoretto; FERNANDES, Ariana Ester; MELO, Maria Edna de; REINHARDT, Heidi Lui; CERCATO, Cintia; VILLARES, Sandra Mara Ferreira; HALPERN, Alfredo; MANCINI, Marcio C.Objective: To analyze the LEPR gene in obese children and to investigate the associations between molecular findings and anthropometric and metabolic features. Subjects and methods: Thirty-two patients were evaluated regarding anthropometric characteristics, blood pressure, heart rate, serum glucose, insulin, leptin levels, and lipid profile. The molecular study consisted of the amplification and automatic sequencing of the coding region of LEPR in order to investigate new mutations. Results: We identified a high prevalence of metabolic disorders: impaired fasting glucose in 12.5% of the patients, elevated HOMA-IR in 85.7%, low HDL-cholesterol levels in 46.9%, high triglyceride levels in 40.6%, and hypertension in 58.6% of the patients. The molecular study identified 6 already described allelic variants: rs1137100 (exon-2), rs1137101 (exon-4), rs1805134 (exon-7), rs8179183 (exon-12), rs1805096 (exon-18), and the deletion/insertion of the pentanucleotide CTTTA at 3'untranslated region. Conclusions: The frequency of alleles observed in this cohort is similar to that described in the literature, and was not correlated with any clinical feature. The molecular findings in the analysis of the LEPR did not seem to be implicated in the etiology of obesity in these patients.
- Non-invasive methods for iron overload evaluation in dysmetabolic patients(2022) BRANISSOA, Paula Pessin Fabrega; OLIVEIRA, Claudia Pinto Marques Souza de; FILHO, Hilton Muniz Leao; LIMA, Fabiana Roberto; SANTOSE, Aritania Sousa; MANCINI, Marcio Correa; MELO, Maria Edna de; CARRILHO, Flair Jose; ROCHA, Manoel de Souza; CLARK, Paul; BRANISSOK, Henrique Jose Pereira; CERCATO, CintiaIntroduction: Although hyperferritinemia may reflect the inflammatory status of patients with non-alcoholic fatty liver disease (NAFLD), approximately 33% of hyperferritinemia cases reflect real hepatic iron overload. Aim: To evaluate a non-invasive method for assessing mild iron overload in patients with NAFLD using 3T magnetic resonance imaging (MRI) relaxometry, serum hepcidin, and the expression of ferritin subunits. Methods: This cross-sectional study assessed patients with biopsy-proven NAFLD. MRI relaxometry was performed using a 3T scanner in all patients, and the results were compared with iron content determined by liver biopsy. Ferritin, hepcidin, and ferritin subunits were assessed and classified according to ferritin levels and to siderosis identified by liver biopsy. Results: A total of 67 patients with NAFLD were included in the study. MRI revealed mild iron overload in all patients (sensitivity, 73.5%; specificity, 70%). For mild (grade 1) siderosis, the transverse relaxation rate (R2*) threshold was 58.9 s-1 and the mean value was 72.5 s-1 (SD, 33.9), while for grades 2/3 it was 88.2 s-1 (SD, 31.9) (p < 0.001). The hepcidin threshold for siderosis was > 30.2 ng/mL (sensitivity, 87%; specificity, 82%). Ferritin H and ferritin L subunits were expressed similarly in patients with NAFLD, regardless of siderosis. There were no significant differences in laboratory test results between the groups, including glucose parameters and liver function tests. Conclusions: MRI relaxometry and serum hepcidin accurately assessed mild iron overload in patients with dysmetabolic iron overload syndrome.(c) 2022 Fundacion Clinica Medica Sur, A.C.
- The new obesity classification based on weight history is not proposed as a guideline(2022) HALPERN, Bruno; MANCINI, Marcio C.; MELO, Maria Edna de; LAMOUNIER, Rodrigo N.; MOREIRA, Rodrigo O.; CARRA, Mario K.; CERCATO, Cintia; BOGUSZEWSKI, Cesar Luiz
- Efficacy and safety of evogliptin in the treatment of type 2 diabetes mellitus in a Brazilian population: a randomized bridging study(2019) CERCATO, Cintia; FELICIO, Joao Soares; RUSSO, Luis Augusto Tavares; BORGES, Joao Lindolfo Cunha; SALLES, Joao; MUSKAT, Patricia; BONANSEA, Teresa; CHACRA, Antonio Roberto; ELIASCHEWITZ, Freddy Goldberg; FORTI, Adriana CostaBackground Evogliptin (EVO) is a potent and selective dipeptidyl peptidase-4 inhibitor (DPP4i) developed for the treatment of type 2 diabetes mellitus (T2DM). DPP4is are known to exhibit a better glucose-lowering effect in Asians compared to other ethnic groups. Once EVO's clinical development program was conducted in Asian patients, this bridging study was designed to validate for the Brazilian population the efficacy and safety of the approved dose regimen (once-daily 5.0 mg). Methods In this randomized, double-blind, double-dummy, parallel trial, 146 patients with T2DM with inadequate glycemic control on diet and exercise (7.5% <= HbA1c <= 10.5%) were randomly assigned to a 12-week once-daily treatment with EVO 2.5 mg (N = 35), EVO 5 mg (N = 36), EVO 10 mg (N = 36), or sitagliptin (SITA) 100 mg (N = 39). Absolute changes (Week 12-baseline) in HbA1c, fasting plasma glucose (FPG) and body weight (BW) were obtained. One-sided one sample t test was used to determine if mean HbA1c reduction in each group was < - 0.5% (beneficial metabolic response). An analysis of covariance estimated the change in HbA1c and FPG adjusted by baseline HbA1c, FPG, body mass index (BMI) and study site. Response rates to treatment were also established. No between-group statistical comparisons were planned. Results HbA1c mean reductions were - 1.26% (90% CI - 1.7%, - 0.8%), - 1.12% (90% CI - 1.4%, - 0.8%), - 1.29% (90% CI - 1.6%, - 1.0%), and - 1.15% (90% CI - 1.5%, - 0.8%) in groups EVO 2.5 mg, EVO 5 mg, EVO 10 mg, and SITA 100 mg, respectively. FPG levels showed a mean increase of 10.89 mg/dL in group EVO 2.5 mg, with significant mean reductions of - 18.94 mg/dL, - 21.17 mg/dL, and - 39.90 mg/dL in those treated with EVO 5 mg, EVO 10 mg, and SITA 100 mg, respectively. BW showed significant reductions of approximately 1 kg in patients treated with EVO 5 mg, EVO 10 mg, and SITA 100 mg. Mean adjusted reductions of HbA1c and FPG levels confirmed the significant clinical benefit of all study treatments. The clinical benefit of EVO's ""target"" dose (5 mg) was confirmed. No safety concerns were identified. Conclusions These results validate for the Brazilian population the approved dose regimen of EVO (once-daily 5 mg). Trial registration ClinicalTrials.gov Identifier: NCT02689362 (first posted on 02/23/2016).
- Genetic Variations in Sweet Taste Receptor Gene Are Related to Chocolate Powder and Dietary Fiber Intake in Obese Children and Adolescents(2018) PIOLTINE, Marina B.; MELO, Maria Edna de; SANTOS, Aritania S.; MACHADO, Alisson D.; FERNANDES, Ariana E.; FUJIWARA, Clarissa T.; CERCATO, Cintia; MANCINI, Marcio C.Childhood obesity is a major public health problem. It has a direct impact on the quality of life of children and adolescents, as well as on their future risk of developing chronic diseases. Dietary patterns rich in fats and sugars and lacking dietary fibers, vitamins, and minerals, as well as lack of physical exercise have been associated with the rise of obesity prevalence. However, factors that contribute to the preference for foods rich in these nutrients are not well established. Taste is recognized as an important predictor of food choices, and polymorphisms in taste-related genes may explain the variability of taste preference and food intake. The aim of this research is to evaluate the influence of polymorphisms of the sweet taste receptor gene TAS1R2 on diet and metabolic profile in obese children and adolescents. A cross-sectional study with 513 obese children and adolescents and 135 normal-weight children was carried out. A molecular study was performed for the single nucleotide polymorphisms (SNPs) rs9701796 and rs35874116 of TAS1R2, and dietary intake, anthropometric parameters (weight, height, waist circumference, waist-to-height ratio (WHtR)), and metabolic profile (including fasting glucose, insulin, triglyceride, high-density lipoprotein (HDL)-cholesterol, and leptin levels) were analyzed. The variant rs9701796 was associated with increased waist-height ratio, as well as with a higher chocolate powder intake in obese children. The variant rs35874116 was associated with a lower dietary fiber intake. In conclusion, there was no relationship between genotypes and risk of obesity. Obese adolescents carrying the serine allele of SNP rs9701796 in TAS1R2 showed higher waist-to-height ratio and chocolate powder intake, whereas those carrying the valine allele of SNP rs35874116 in TAS1R2 were characterized by lower dietary fiber intake.
- Cardiovascular risk and obesity(2019) CERCATO, C.; FONSECA, F. A.BackgroundThis is an overview of the mechanisms of obesity and its relation to cardiovascular risks, describing the available treatment options to manage this condition.Main bodyThe pathogenesis of obesity includes the balance between calories consumed and energy expenditure followed by the maintenance of body weight. Diet, physical activity, environmental, behavioral and physiological factors are part of the complex process of weight loss, since there are several hormones and peptides involved in regulation of appetite, eating behavior and energy expenditure. The cardiovascular complications associated to obesity are also driven by processes involving hormones and peptides and which include inflammation, insulin resistance, endothelial dysfunction, coronary calcification, activation of coagulation, renin angiotensin or the sympathetic nervous systems. Pharmacological treatments are often needed to insure weight loss and weight maintenance as adjuncts to diet and physical activity in people with obesity and overweight patients.ConclusionTo accomplish satisfactory goals, patients and physicians seek for weight loss, weight maintenance and improvement of the risk factors associated to this condition, especially cardiovascular risk.
- Brazilian evidence-based guideline for screening, diagnosis, treatment, and follow-up of metabolic dysfunction-associated steatotic liver disease (MASLD) in adult individuals with overweight or obesity: A joint position statement from the Brazilian Society of Endocrinology and Metabolism (SBEM), Brazilian Society of Hepatology (SBH), and Brazilian Association for the Study of Obesity and Metabolic Syndrome (Abeso)(2023) MOREIRA, Rodrigo Oliveira; VALERIO, Cynthia Melissa; VILLELA-NOGUEIRA, Cristiane Alves; CERCATO, Cintia; GERCHMAN, Fernando; LOTTENBERG, Ana Maria Pita; GODOY-MATAS, Amelio Fernando; OLIVEIRA, Ricardo de Andrade; MELLO, Carlos Eduardo Brandao; ALVARES-DA-SILVA, Mario Reis; LEITE, Nathalie Carvalho; COTRIM, Helma Pinchemel; PARISI, Edison Roberto; SILVA, Giovanni Faria; MIRANDA, Paulo Augusto Carvalho; HALPERN, Bruno; OLIVEIRA, Claudia PintoIntroduction: Metabolic dysfunction-associated steatotic liver disease (MASLD), previously known as Nonalcoholic fatty liver disease (NAFLD), is one of the most common hepatic diseases in individuals with overweight or obesity. In this context, a panel of experts from three medical societies was organized to develop an evidence-based guideline on the screening, diagnosis, treatment, and follow-up of MASLD. Material and methods: A MEDLINE search was performed to identify randomized clinical trials, meta-analyses, cohort studies, observational studies, and other relevant studies on NAFLD. In the absence of studies on a certain topic or when the quality of the study was not adequate, the opinion of experts was adopted. Classes of Recommendation and Levels of Evidence were determined using prespecified criteria. Results: Based on the literature review, 48 specific recommendations were elaborated, including 11 on screening and diagnosis, 9 on follow-up, 14 on nonpharmacologic treatment, and 14 on pharmacologic and surgical treatment. Conclusions: A literature search allowed the development of evidence-based guidelines on the screening, diagnosis, treatment, and follow-up of MASLD in individuals with overweight or obesity.

Only patients positive for COVID-19 (real-time PCR or serology) were included. Data were collected from medical records and included clinical and demographic information, weight and height, SAPS-3 score, comorbidities, and patient-centered outcomes (mortality, and need for mechanical ventilation, renal replacement therapy, or vasoactive drugs). Patients were divided into categories according to their BMI (underweight, eutrophic, overweight and obesity) for comparison porpoise.Results A total of 2547 patients were included. The mean age was 60.3 years, 56.2% were men, 65.2% were white and the mean BMI was 28.1 kg/m(2). SAPS-3 score was a risk factor for all patient-centered outcomes (HR 1.032 for mortality, OR 1.03 for dialysis, OR 1.07 for vasoactive drug use, and OR 1.08 for intubation, p < 0.05). Male sex increased the risk of death (HR 1.175, p = 0.027) and dialysis (OR 1.64, p < 0.001), and underweight was protective for vasoactive drug use (OR 0.45, p = 0.027) and intubation (OR 0.31, p < 0.003).Conclusion Obesity itself was not an independent factor for worse patient-centered outcomes. Critical clinical state (indirectly evaluated by SAPS-3) appears to be the most important variable related to hard outcomes in patients infected with COVID-19.
