RESUMO

BACKGROUND: Mesenchymal stem cell infusion and vitamin D supplementation may have immunomodulatory actions that could prolong the preservation of residual insulin secretion in patients with type 1 diabetes (T1D). Intervention with these agents after onset of T1D could favor the development of a remission phase, with potential clinical impact. We aimed to compare the presence of clinical remission (CR), glycemic control and daily insulin requirement at 6, 12, 18, 24 and 36 months after the diagnosis of T1D using IDAA1c in patients who received therapy with adipose tissue-derived mesenchymal stem cell (ASC) infusion and vitamin D supplementation and a control group. METHODS: This retrospective cohort study analyzed data from the medical records of patients with T1D diagnosed between 15 and 40 years. Partial CR was defined as an IDAA1c index < 9. Patients in the intervention group received an infusion of adipose tissued-derived mesenchymal stem cells (ASCs) within 3 months after diagnosis and supplementation with 2000 IU of cholecalciferol for 1 year, started on the day following the infusion. Partial CR was also determined using the ISPAD criteria, to assess its agreement with IDAA1c. RESULTS: A total of 28 patients were evaluated: 7 in the intervention group (group 1) and 21 in the control group (group 2). All patients in group 1 evolved with partial CR while only 46.7% of patients in group 2 had this outcome. Group 1 had a higher frequency of CR when evaluated with IDAA1c and ISPAD criteria. The mean duration of CR varied between the two criteria. Although HbA1c was similar between groups during follow-up, group 1 had a lower total daily insulin requirement (p < 0.005) at all time points. At 36 months, group 1 used 49% of the total daily insulin dose used by group 2 with similar glycemic control. CONCLUSION: The intervention with infusion of ASC + vitamin D supplementation was associated with partial CR at 6 months. Although there were no differences in CR established by the IDAA1c and ISPAD criteria after three years of follow-up, patients who underwent intervention had nearly the half insulin requirement of controls with conventional treatment, with similar glycemic control. TRIAL REGISTRATION: 37001514.0.0000.5257.

RESUMO

ABSTRACT Objective: Binge eating disorder (BED) is the most prevalent eating disorder in individuals with obesity. Its association with factors that control hunger and satiety has not yet been elucidated. We evaluated whether levels of inflammatory markers, frequency of psychiatric comorbidities, and appetite-related hormones levels differ between individuals with obesity with and without BED. Materials and methods: The Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders-5 - Clinician Version (SCID-5-CV), Binge Eating Scale, and Hospital Anxiety and Depression Scale were evaluated in 39 individuals with obesity. Plasma levels of C-reactive protein (CRP), tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), leptin, ghrelin, and glucagon-like peptide-1 (GLP-1) were measured. Results: Individuals of the BED group exhibited significantly higher percentages of altered eating patterns (hyperphagia, bingeing, post-dinner eating, feeling "stuffed", and emotional eating), higher depressive symptom scores and levels of leptin, CRP, and TNF-α, compared to those from the non-BED group. Logistic regression showed that BED was independently associated with depressive symptoms and CRP levels. Conclusions: Individuals with obesity and BED showed greater psychiatric comorbidity, worse eating patterns and worse inflammatory profile than those without BED. BED should be assessed as an indicator of clinical severity in patients with obesity.

RESUMO

ABSTRACT Objective: The aim of the study was to assess the autoimmunity in first degrees relatives (FDR) of patients with type 1 diabetes (T1DM) and the progression to T1DM after 10 years of follow up in the Brazilian population. Subjects and methods: Non-diabetic FDR of T1DM patients were interviewed and blood was drawn for autoantibodies measurement (GADA, IA-2A, IAA, ZnT8A). Serum samples were analyzed by standard radioligand binding assays performed at the Federal University of Rio de Janeiro (GADA, IAA and IA2A), and at the Skäne University Hospital, Sweden (ZnT8A). The FDR were interviewed by phone after 10 years to determine if they had developed T1DM. Descriptive statistical analysis was performed and results were described as means and standard deviation (SD). Results: 81 individuals were analyzed. Thirteen subjects had positive autoantibodies associated with T1DM.10 were positive for 1 autoantibody and 3 subjects were positive for multiple autoantibodies (1 of them showed positivity for 2 autoantibodies - GADA, ZnT8A - and the other two were positive for 3 autoantibodies - GADA, IA2A, ZnT8A). The 3 subjects with multiple positive autoantibodies developed T1DM within 10 years. Conclusions: In Brazilian FDR of T1DM patients, the positivity for multiple autoantibodies indicate a greater chance of progression to T1DM, similar to observed in Caucasians. ZnT8A was helpful in the risk assessment for T1DM development.

RESUMO

ABSTRACT Objective: Adipose tissue-derived stromal/stem cells (ASCs) and vitamin D have immunomodulatory actions that could be useful for type 1 diabetes (T1D). We aimed in this study to investigate the safety and efficacy of ASCs + daily cholecalciferol (VIT D) for 6 months in patients with recent-onset T1D. Materials and methods: In this prospective, dual-center, open trial, patients with recent onset T1D received one dose of allogenic ASC (1 x 106 cells/kg) and cholecalciferol 2,000 UI/day for 6 months (group 1). They were compared to patients who received chol-ecalciferol (group 2) and standard treatment (group 3). Adverse events were recorded; C-peptide (CP), insulin dose and HbA1c were measured at baseline (T0), after 3 (T3) and 6 months (T6). Results: In group 1 (n = 7), adverse events included transient headache (all), mild local reactions (all), tachycardia (n = 4), abdominal cramps (n = 1), thrombophlebitis (n = 4), scotomas (n = 2), and central retinal vein occlusion at T3 (n = 1, resolution at T6). Group 1 had an increase in basal CP (p = 0.018; mean: 40.41+/-40.79 %), without changes in stimulated CP after mixed meal (p = 0.62), from T0 to T6. Basal CP remained stable in groups 2 and 3 (p = 0.58 and p = 0.116, respectively). Group 1 had small insulin requirements (0.31+/- 0.26 UI/kg) without changes at T6 (p = 0.44) and HbA1c decline (p = 0.01). At T6, all patients (100%; n = 7) in group 1 were in honeymoon vs 75% (n = 3/4) and 50% (n = 3/6) in groups 2 and 3, p = 0.01. Conclusions: Allogenic ASC + VIT D without immunosuppression was safe and might have a role in the preservation of β-cells in patients with recent-onset T1D. ClinicalTrials.gov: NCT03920397.

RESUMO

INTRODUCTION: To evaluate the efficacy and clinical safety of bariatric arterial embolization (BAE) in adults with body mass index (BMI) between 30 and 39.9 kg/m2 and metabolic syndrome (MS). MATERIALS AND METHODS: Between March and August 2018, ten female participants between 21 and 48-years-old, median BMI of 36.37 ± 2.58 kg/m2 and MS were enrolled in this prospective trial. We embolized the fundal branches from the left gastric and other artery sources, which resulted in embolization of at least two arteries in 9 out 10 participants. Six months after bariatric embolization, efficacy was assessed by changes in total body weight (TBW), ghrelin and Homeostatic Model Assessment-Insulin Resistance (HOMA-IR) levels and by changes in quality of life (QOL) and in binge eating scale (BES) scores. Safety was assessed by the identification of any related complications, including gastric ulcers, screened by gastrointestinal endoscopy, performed before and one week and one month after BAE. RESULTS: Six months after embolization, TBW decreased by 6.8% (6.22 kg ± 3.6;p = .01), serum ghrelin dropped from 25.39 pg/ml ± 10.63 to 17.1 ± 8.07 (p = 0.01), and HOMA-IR decreased from 7.29 ± 5.66 to 3.73 ± 1.99 (p = 0.01). The QOL scores improved from 59.64 ± 5.59 to 69.02 ± 11.97 (p < 0.05) and in the BES from 21.50 ± 8.89 to 9.60 ± 4.40 (p = 0.01). Endoscopy revealed symptomatic gastric ulcers in two participants, which had healed without sequelae. In one participant, ultrasound revealed an asymptomatic focal arterial thrombus at the left distal radial artery puncture site. CONCLUSION: BAE is effective in reducing weight, insulin resistance and ghrelin levels and improving BES and QOL scores in patients with class I and II obesity and MS, with no major complications.

RESUMO

ABSTRACT Objective To test the influence of oral fructose and glucose dose-response solutions in blood glucose (BG), glucagon, triglycerides, uricaemia, and malondialdehyde in postprandial states in type 1 diabetes mellitus (T1DM) patients. Subjects and methods The study had a simple-blind, randomized, two-way crossover design in which T1DM patients were selected to receive fructose and glucose solutions (75g of sugars dissolved in 200 mL of mineral-water) in two separate study days, with 2-7 weeks washout period. In each day, blood samples were drawn after 8h fasting and at 180 min postprandial to obtain glucose, glucagon, triglycerides, uric acid, lactate, and malondialdehyde levels. Results Sixteen T1DM patients (seven men) were evaluated, with a mean age of 25.19 ± 8.8 years, a mean duration of disease of 14.88 ± 4.73 years, and glycated hemoglobin of 8.13 ± 1.84%. Fructose resulted in lower postprandial BG levels than glucose (4.4 ± 5.5 mmol/L; and 12.9 ± 4.1 mmol/L, respectively; p < 0.01). Uric acid levels increased after fructose (26.1 ± 49.9 µmol/L; p < 0.01) and reduced after glucose (-13.6 ± 9.5 µmol/L; p < 0.01). The malondialdehyde increased after fructose (1.4 ± 1.6 µmol/L; p < 0.01) and did not change after glucose solution (-0.2 ± 1.6 µmol/L; p = 0.40). Other variables did not change. Conclusions Fructose and glucose had similar sweetness, flavor and aftertaste characteristics and did not change triglycerides, lactate or glucagon levels. Although fructose resulted in lower postprandial BG than glucose, it increased uric acid and malondialdehyde levels in T1DM patients. Therefore it should be used with caution. ClinicalTrials.gov registration: NCT01713023.

RESUMO

Objective Thyroid diseases are common in individuals with type 1 diabetes mellitus (T1DM) and should be investigated annually in these individuals. The aim of this study was to evaluate the frequency of thyroid diseases in first degree relatives (FDR) of patients with T1DM. Subjects and methods Eighty individuals (40 patients with T1DM and 40 FDR) were interviewed and blood was sampled for thyroid-stimulating hormone (TSH), free thyroxine (FT4) and thyroid peroxidase (TPO) antibodies measurement. Autoantibodies against glutamic acid decarboxylase 65 (GAD65), islet antigen-2 (IA2) and autoantibodies against insulin (AAI) were measured in FDR. Results We found a similar prevalence of thyroid dysfunction in patients with T1DM and their FDR (22.5% vs. 27.5%; p = 0,79). There were no differences in serum TSH levels (p = 0.29), FT4 (p = 0,45), frequency of abnormal TSH (p = 0.28), positive TPO antibodies (p = 0.13), titers of TPO antibodies (in positive cases) between patients with T1DM and their FDR (p = 0.94). Conclusions Thyroid abnormalities seem to be common not only in patients with T1DM but also in their FDR, which suggests that screening strategies for thyroid diseases might also be useful to these individuals. .

RESUMO

Objective Zinc transporter 8 autoantibodies (ZnT8A) have been poorly studied in non-Caucasian individuals. We aimed to investigate the prevalence of ZnT8 autoantibodies in patients with T1D and their first degree relatives (FDR) from a multiethnic population, as well as its relation with the insulin (INS) or the protein tyrosine phosphatase non-receptor 22 (PTPN22) gene polymorphisms. Subjects and methods ZnT8A were analyzed in sera from T1D patients (n = 72, mean age of 30.3 ± 11.4 years) of variable duration (15.7 ± 11.8 years) and their FDR (n = 78, mean age of 18.3 ± 9.1 years) by a triple mix Radioligand Binding Assay (RBA) for the ZnT8 autoantibody (ZnT8-RWQ) variants. SNP (single nucleotide polymorphism) for INS and PTPN22 were genotyped. Results The prevalence of ZnT8A was higher in T1D patients than FDR, for ZnT8TripleA (24% vs. 4%,p = 0.001), ZnT8RA (24% vs. 4%, p < 0.001) and ZnT8QA (15% vs. 3%, p = 0.004). All FDR with ZnT8A (n = 3) had at least another positive antibody. Heterozygosis for PTPN22 was associated with a higher frequency of ZnT8TripleA (p = 0.039) and ZnT8RA (p = 0.038). Conclusions ZnT8A is observed in non-Caucasian patients with T1D, even years after the disease onset, as well as in their FDR. In those, there was an overlap between ZnT8A and other T1D antibodies. ZnT8A was associated with PTPN22 polymorphisms. Further longitudinal studies are necessary to elucidate the importance of these findings in the natural history of T1D patients with multiethnic background. .


Objetivo Os autoanticorpos transportadores de zinco 8 (ZnT8A) foram pouco estudados em indivíduos não caucasianos. Nosso objetivo foi investigar a prevalência de autoanticorpos ZnT8 em pacientes com T1D e seus parentes de primeiro grau (PPG) em uma população multiétnica, assim como a sua relação com os polimorfismos genéticos da insulina (INS) ou proteína tirosina fosfatase não receptora tipo 22 (PTPN22). Sujeitos e métodos ZnT8A foram analisados no soro de pacientes com T1D (n = 72, idade média de 30,3 ± 11,4 anos) de duração variável (15,7 ± 11,8 anos) e seus PPG (n = 72, idade média de 30,3 ± 11,4 anos) usando-se um ensaio de competição com radioligantes (RBA) para variantes dos autoanticorpos ZnT8 (ZnT8-RWQ). Os polimorfismos de nucleotídeo único para a INS e PTPN22 foram genotipados. Resultados A prevalência de ZnT8A foi mais alta em pacientes T1D do que nos PPG, para ZnT8TriploA (24% contra 4%, p = 0,001), ZnT8RA (24% contra 4%, p < 0,001) e ZnT8QA (15% contra 3%, p = 0,004). Todos os PPG com ZnT8A (n = 3) apresentaram positividade para pelo menos outro anticorpo. A heterozigose para PTPN22 foi associada a uma frequência mais alta de ZnT8TriploA (p = 0,039) e de ZnT8RA (p = 0,038). Conclusões Os ZnT8A foram observados em pacientes não caucasianos com T1D, mesmo depois de anos do início da doença, assim como em seus PPG. Nos parentes, houve uma sobreposição entre os ZnT8A e outros anticorpos para T1D. Os ZnT8A mostraram-se associados aos polimorfismos PTPN22. São necessários outros estudos longitudinais para se elucidar a importância desses achados na história natural de pacientes com T1D com antecedentes étnicos variados. .

RESUMO

A hipoglicemia é um evento potencialmente grave, com significativa morbidade. É rara em indivíduos sem diabetes, e pode ocorrer com frequência variável em pacientes com diabetes mellitus, especialmente naqueles que utilizam insulina. Para minimizar esse risco é imprescindível que se individualize o tratamento, estabelecendo metas glicêmicas de acordo com a idade, expectativa de vida, comorbidades e estilo de vida


Hypoglycemia is a potentially serious event with significant morbidity. It is rare in individuals without diabetes and can occur in a quite variable frequency in diabetic patients, especially in those that use insulin. In order to minimize its risk in these groups, it is essential to individualize treatment, establishing glycemic targets according to age, life expectancy, comorbidities and lifestyle
