Congenital hyperinsulinism and surgical outcome in a single tertiary center in Brazil

Abstract Objective: Congenital hyperinsulinism (CHI) is a heterogeneous genetic disease characterized by increased insulin secretion and causes persistent hypoglycemia in neonates and infants due to dysregulation of insulin secretion by pancreatic β cells. Babies with severe hypoglycemia and for whom medical treatment has been ineffective usually require surgical treatment with near-total pancreatectomy. To evaluate the clinical and surgical aspects affecting survival outcomes in babies diagnosed with CHI in a single tertiary care center. Methods: Retrospective Cohort study involving a single university tertiary center for the treatment of CHI. The authors study the demographics, clinical, laboratory, and surgical outcomes of this casuistic. Results: 61 % were female, 39 % male, Birth weight: 3576 g (±313); Age of onset of symptoms: from the 2nd hour of life to 28 days; Time between diagnosis and surgery ranged between 10 and 60 days; Medical clinical treatment, all patients received glucose solution with a continuous glucose infusion and diazoxide. 81 % of the patients used corticosteroids, 77 %. thiazide, 72 % octreotide, 27 % nifedipine; Neurological sequelae during development and growth: 54 % had some degree of delay in neuropsychomotor development, 27 % obesity. Surgery was performed open in 6 and 12 minimally invasive surgery (MIS). Histopathology: 2 focal and 16 diffuse, Length of stay (days) was lower in MIS (p < 0.05). Survival was 100 %. Conclusions: CHI is a rare and difficult-to-manage tumor that must be performed in a multidisciplinary and tertiary center. Most surgical results are good and the laparoscopic approach to disease has been the best choice for patients.

Carbohydrate counting and insulin analogs to treat type 1 diabetes mellitus. How to improve metabolic control?

Abstract Objectives: Clinical-laboratory comparison of a population of children and adolescents with DM1 followed at a Brazilian outpatient university clinic, at two different periods (2014 and 2020), regarding changes made both to the insulin therapy scheme and to the nutritional approach to carbohydrate counting. Methods: The data of patients with DM1 aged 0-19 years enrolled in the service in 2014 and 2020 were collected. Student's t-test was performed to compare the means of HbA1c and the variables of interest. Results: NPH + regular insulin was predominantly used in 2014 (49.1%), while in 2020, the predominance shifted to insulin analogs (48.4%). Pump use tripled from 1.3% in 2014 to 4.4% in 2020, and the percentage of patients performing carbohydrate counting reduced from 28.3% to 17.8%. Regarding HbA1c, the 2014 group of patients had a mean of 9.8%, while the 2020 group had a mean of 9.6% (p = 0.49). Conclusion: The change in treatments between 2014 and 2020 did not result in a significant improvement in HbA1c levels. However, it was identified the importance of carbohydrate counting and the use of insulin analogs to improve metabolic control in this population at both times.

Continuous interstitial glucose monitoring for term newborns: analysis of the first day of life.

OBJECTIVE: Glycaemia in newborns changes significantly after birth; however, little is known about these changes. The objective was to describe continuous interstitial glucose values in term newborns who were exclusively breast fed on the first day of life. DESIGN: We studied 159 newborns with appropriate weights for gestational age, who were exclusively breast fed on the first day of life, using a continuous glucose monitoring device that calculates interstitial glucose every 5 min. The device was removed after 24 hours, and the results were analysed using the R program, which provides the minimum, maximum, median and a standard curve with centiles. RESULTS: At the second hour of life, the moment in which the sensor started to identify the newborn's glycaemia, interstitial glucose levels were 2.59-4.43 mmol/L (46.7-79.9 mg/dL). The median interstitial glucose level of the newborns during the first day of life was 3.33±0.48 mmol/L (60±8.6 mg/dL). Interstitial glucose levels dropped until the sixth hour of life, reaching 2.19-3.95 mmol/L (39.5-71.1 mg/dL), and then increased again. The maximum values were found at the 20th and 21st hours of life, which were 2.81-4.64 mmol/L (50.6-83.6 mg/dL). CONCLUSION: The interstitial glucose during the first 24 hours of life declined until the sixth hour of life, then increased around the 20th hour and remained stable until the end of the first day of life.

Teleconsultation for pediatric patients with type 1 diabetes mellitus during the COVID-19 pandemic: experience of a university hospital in Brazil

Abstract Objective: Evaluate the impact of teleconsultation on glycemic control and prevention of acute complications related to diabetes mellitus in children and adolescents treated in a reference hospital during the COVID-19 pandemic in 2020. Method: Descriptive study of data from pediatric diabetic patients who received teleconsultation between April and September 2020. Results: During this period, 143 diabetic patients were evaluated, with a median of 3.4 teleconsultations per patient in the studied period, requiring adjustment of insulin doses in 84.6% of cases. The hospital admission rate was 8,4% due to diabetic decompensation. The metabolic control (HbA1c) became worse in 46% of the sample and improved in 37%. Conclusion: The teleconsultation promoted health care for patients with diabetes mellitus during the COVID-19 pandemic but was not able to guarantee adequate glycemic control.

DKA and new-onset type 1 diabetes in Brazilian children and adolescents during the COVID-19 pandemic

ABSTRACT We assess the severity and frequency of diabetic ketoacidosis (DKA) in new-onset type 1 diabetes mellitus (T1D) patients and in patients with previous diagnosis of T1D in a referral Brazilian university hospital in the first five months of the COVID-19 pandemic. We also compare the data with data from pre-pandemic periods. Forty-three new-onset T1D patients were diagnosed between April and August of the years 2017, 2018, 2019, and 2020. During the COVID-19 pandemic, the number of new-onset T1D was over twice the number of new-onset T1D in the same period in the three previous years. All the 43 patients survived and are now on outpatient follow-up. We also compared the characteristics of the T1D patients hospitalized between April and August of the years 2017, 2018, and 2019 (32 hospitalizations) to the characteristics of the T1D patients hospitalized between April and August/2020 (35 hospitalizations; 1 patient was hospitalized twice in this period). Fourteen of the 34 patients admitted during the pandemic presented with COVID-19-related symptoms (any respiratory symptom, fever, nausea, vomiting, and diarrhea), but only one had positive SARS-CoV-2 RT-PCR test. Samples from 32 out of these 34 patients were assayed for SARS-CoV-2 antibodies, and four patients were positive for total antibodies (IgM and IgG). In agreement with recent reports from European countries, we observed increased frequency of DKA and severe DKA in new-onset and previously diagnosed T1D children and adolescents in a large referral public hospital in Brazil in the first five months of the COVID-19 pandemic. The reasons for this outcome might have been fear of SARS-CoV-2 infection in emergency settings, the more limited availability of primary healthcare, and the lack of school personnel's attention toward children's general well-being.

Continuous insulin therapy versus multiple insulin injections in the management of type 1 diabetes: a longitutinal study / Insulinoterapia contínua versus múltiplas injeções de insulina no tratamento da diabetes tipo 1: um estudo longitudinal

To compare multiple doses of insulin and continuous insulin infusion therapy as treatment for type 1 diabetes mellitus. Methods: 40 patients with type 1 diabetes mellitus (21 female) with ages between 10 and 20 years (mean=14.2) and mean duration of diabetes of 7 years used multiple doses of insulin for at least 6 months and after that, continuous insulin infusion therapy for at least 6 months. Each one of the patients has used multiple doses of insulin and continuous insulin infusion therapy. For analysis of HbA1c, mean glycated hemoglobin levels (mHbA1c) were obtained during each treatment period (multiple doses of insulin and continuous insulin infusion therapy period). Results: Although mHbA1c levels were lower during continuous insulin infusion therapy the difference was not statistically significant. During multiple doses of insulin, 14.2% had mHbA1c values below 7.5% vs. 35.71% while on continuous insulin infusion therapy; demonstrating better glycemic control with the use of continuous insulin infusion therapy. During multiple doses of insulin, 15–40 patients have severe hypoglycemic events versus 5–40 continuous insulin infusion therapy. No episodes of ketoacidosis events were recorded. Conclusions: This is the first study with this design comparing multiple doses of insulin and continuous insulin infusion therapy in Brazil showing no significant difference in HbA1c; hypoglycemic events were less frequent during continuous insulin infusion therapy than during multiple doses of insulin and the percentage of patients who achieved a HbA1c less than 7.5% was greater during continuous insulin infusion therapy than multiple doses of insulin therapy.

Comparar terapia com múltiplas doses de insulina e o sistema de infusão continua de insulina no tratamento da diabetes melito tipo 1. Métodos: 40 pacientes com diabetes melito tipo 1 (21 mulheres) com idades entre 10 e 20 anos (média=14,2) e duração média do diabetes de sete anos utilizaram múltiplas doses de insulina durante pelo menos seis meses e, depois disso, sistema de infusão continua de insulina por pelo menos seis meses. Todos os pacientes usaram múltiplas doses de insulina e sistema de infusão continua de insulina. Para a análise de HbA1c, níveis médios de hemoglobina glicada (mHbA1c) foram obtidos em cada período de tratamento (múltiplas doses de insulina e sistema de infusão continua de insulina). Resultados: Embora os níveis de mHbA1c tenham sido menores com o uso de sistema de infusão continua de insulina a diferença não foi estatisticamente significante. Durante o uso de múltiplas doses de insulina, 14,2% tiveram valores de mHbA1c <7,5% vs. 35,71% quando usando sistema de infusão continua de insulina; demonstrando melhor controle glicêmico com o uso de sistema de infusão continua de insulina. Durante o uso de múltiplas doses de insulina, 15-40 pacientes tiveram eventos hipoglicêmicos graves contra 5–40 com sistema de infusão continua de insulina. Não foram registrados episódios de cetoacidose. Conclusões: Esse é o primeiro estudo cujo desenho comparou o uso de múltiplas doses de insulina e sistema de infusão continua de insulina no Brasil, não demonstrando nenhuma diferença significativa nos níveis de HbA1c. Eventos hipoglicêmicos foram menos frequentes com o uso de sistema de infusão continua de insulina do que com múltiplas doses de insulina e a porcentagem de pacientes que obteve um HbA1c <7,5% foi maior com sistema de infusão continua de insulina do que com múltiplas doses de insulina.

Avaliação de depressão, problemas de comportamento e competência social em crianças obesas

O objetivo deste estudo foi avaliar a ocorrência de depressão, problemas comportamentais e competência social em crianças obesas, comparativamente a crianças não obesas. Participaram do estudo 90 crianças, das quais 60 eram obesas e 30 não eram, com idade entre 7 e 13 anos. Na coleta de dados foram utilizados: Ficha de Identificação, Inventário de Depressão para Crianças e Inventário de Comportamentos da Infância e Adolescência. Os dados foram analisados quantitativamente, com testes estatísticos não paramétricos e paramétricos, com nível de significância de 0,05. Os resultados apontaram diferença significativa entre as crianças obesas e as crianças não obesas em relação às variáveis psicológicas estudadas. Na análise multivariada, a depressão e os distúrbios internalizantes foram as variáveis que mais discriminaram as crianças obesas das não obesas. Os dados indicam, portanto, a necessidade de uma intervenção precoce e a realização de programas de prevenção.(AU)

Ninety children, ages between 7 and 13, participated in this study; 60 were obese and 30 were not. Data was collected using the following methods: Identity Cards; Children's Depression Inventory and the Child Behavior Checklist. Data analysis was performed quantitatively, using parametric and non-parametric statistical tests, with a significance level of 0.05. Results demonstrated a significant difference between obese and non-obese children, as regards the psychological variables studied. Based on a multivante analysis, depression and internal disorders distinguished obese children from those who were not obese. The data indicates, however, that there is a need for early intervention and a need to establish programs of prevention.(AU)

Perfil clínico e laboratorial de pacientes pediátricos e adolescentes com diabetes tipo 1 / Clinical and laboratory profile of pediatric and adolescent patients with type 1 diabetes

OBJETIVO: Realizar a avaliação clínica e laboratorial dos pacientes com diabetes melito tipo 1 em três hospitais públicos em São Paulo (SP), uma vez que o diabetes melito tipo 1 é uma doença crônica que ocorre principalmente em crianças e adolescentes. MÉTODOS: Estudo transversal com pacientes em acompanhamento em centros de referência em São José do Rio Preto (FAMERP), Campinas (UNICAMP) e São Paulo (Conjunto Hospitalar do Mandaqui). Dados como gênero, idade, duração do diabetes, dose diária de insulina, número de aplicações diárias de insulina e hemoglobina glicosilada (HbA1c) foram analisados. RESULTADOS: Foram avaliados 239 pacientes (131 do sexo feminino); a idade média foi de 13,1±4,7 anos e o tempo médio de duração do diabetes foi de 6,6±4,2 anos. As doses diárias de insulina variaram de 0,1 a 1,78 unidades/kg/dia (0,88±0,28), e 180 (74,7 por cento) pacientes faziam somente duas aplicações por dia. A HbA1c variou de 4,6 a 17,9 por cento (10,0±2,3 por cento). CONCLUSÕES: Embora os hospitais incluídos neste estudo sejam centros de referência para o seguimento de pacientes com diabetes melito em três cidades do estado de São Paulo, um dos estados mais desenvolvidos do Brasil, o controle da glicemia avaliado através da HbA1c não foi adequado. Isso confirma o fato de que, embora haja esforço de todos os profissionais envolvidos, grandes desafios ainda deverão ser vencidos.

OBJECTIVE: To evaluate clinical and laboratory profiles of patients with type 1 diabetes mellitus in three public hospitals in São Paulo, Brazil, since type 1 diabetes mellitus is a chronic illness that occurs mainly in the pediatric age group in the Brazilian population. METHODS: Cross-sectional study with patients followed up in reference centers in São José do Rio Preto (FAMERP), Campinas (UNICAMP) and São Paulo (Conjunto Hospitalar do Mandaqui). Data about gender, age, diabetes duration, daily insulin dose, number of daily insulin injections, and glycosylated hemoglobin (HbA1c) were analyzed. RESULTS: Two hundred and thirty-nine patients (131 females) were evaluated; mean age was 13.1±4.7 years and mean diabetes duration was 6.6±4.2 years. Daily insulin doses ranged from 0.1 to 1.78 units/kg/day (0.88±0.28), and 180 (74.7 percent) patients had two daily injections. HbA1c ranged from 4.6 to 17.9 percent (10.0±2.3 percent). CONCLUSIONS: Although the hospitals included in this study are excellence centers for the follow-up of patients with diabetes in three municipalities in the state of São Paulo, one of the most developed states in Brazil, blood glucose control evaluated according to HbA1c was not adequate. Findings confirm that, despite the efforts of all the professionals involved, great challenges still lie ahead.

Association between obesity and asthma among teenagers.

CONTEXT AND OBJECTIVE: Obesity and asthma are serious and growing problems. Since adipose tissue produces inflammatory substances, the aim of this study was to estimate the prevalence of asthma among students at schools in São José do Rio Preto (Phase 1), and to corroborate the hypothesis for an association between obesity and asthma among these students (Phase 2). DESIGN AND SETTING: Cross-sectional study at Faculdade de Medicina de São José do Rio Preto (Famerp). METHODS: The study consisted of two successive and dependent stages. Phase I was a cross-sectional study on 4103 randomly selected students (13-14 years old), to determine the prevalence and severity of asthma. Phase II was an analytical cross-sectional study on 431 students (190 asthmatics and 231 non-asthmatics) from Phase I, to evaluate the hypothesis of an association between obesity measured by the body mass index (BMI) and asthma. To diagnose asthma and obesity, the criteria of the International Study of Asthma and Allergies in Childhood (ISAAC) and the chart from the Centers for Disease Control (CDC; 2000) were used. The data were analyzed using Student's t test. RESULTS: We found that 5.6% of the students analyzed in Phase I were asthmatic. The BMI among the asthmatic students (21.84 kg/m(2)) was higher than the BMI among the non-asthmatics (21.73 kg/m(2)), although the p value was 0.766. CONCLUSION: In our study group, we did not find any association between increased BMI and the prevalence of asthma.

CONTEXTO AND OBJETIVO: Obesidade e asma são sérios e crescentes problemas em nossa sociedade. Como o tecido adiposo produz substâncias inflamatórias, o objetivo foi estimar a prevalência de asma entre os estudantes (Fase 1), e verificar uma hipótese de associação entre obesidade e asma (Fase 2), em escolares de São José do Rio Preto, São Paulo. TIPO DE ESTUDO E LOCAL: Estudo transversal realizado pela Faculdade de Medicina de São José do Rio Preto (Famerp), São Paulo. MÉTODOS: O estudo foi realizado em duas etapas sucessivas e dependentes. A Fase I, em estudo transversal de prevalência com 4.103 escolares (13-14 anos de idade), para determinar a prevalência e a gravidade da asma. A Fase II, transversal analítico, com 431 (190 asmáticos e 231 não asmáticos), provenientes do grupo da Fase I, avaliou a associação entre obesidade, classificada por índice de massa corporal (IMC) e asma. As amostras foram selecionadas aleatoriamente. Para os diagnósticos de asma e obesidade foram empregados os critérios do International Study of Asthma and Allergies in Childhood (ISAAC) e a tabela do Centers for Disease Control (CDC) 2000. Os dados obtidos foram analisados utilizando o teste t de Student. RESULTADOS: Notou-se que 5,6 por cento do grupo analisado na Fase I são asmáticos; e observou-se um aumento do IMC de asmáticos (21,8 kg/m²) em relação ao dos não-asmáticos (21,73 kg/m²). No entanto, o valor de p obtido foi de 0,766. CONCLUSÃO: Neste estudo não foi encontrada uma associação entre IMC elevado e prevalência de asma, no grupo estudado.

Prevalência de obesidade em crianças e adolescentes com diabetes melito tipo 1 / Prevalence of obesity in children and adolescents with type 1 diabetes mellitus

OBJETIVO: Conhecer a prevalência de obesidade e sua distribuição por sexo e idade em pacientes com diabetes melito tipo 1 (DM1), em acompanhamento em Serviço de Endocrinologia Pediátrica. MÉTODOS: Estudo transversal descritivo de pacientes em acompanhamento no Serviço de Endocrinologia Pediátrica do Hospital de Base de São José do Rio Preto, avaliando as seguintes variáveis: sexo, idade, dose e número de aplicações diárias de insulina, hemoglobina glicada (HbA1c), peso, estatura e índice de massa corpórea (IMC). A definição de sobrepeso e obesidade baseou-se nas curvas de IMC para a idade do Centers for Disease Control and Prevention (CDC, 2000). RESULTADOS: Foram incluídos 77 portadores de DM1 (44 meninas e 33 meninos) com idade entre três e 18 anos (média: 13,4). A determinação de HbA1c variou de 4,1 a 10,6 por cento (média: 7,7 por cento) e o IMC, de 15,1 a 28,6 kg/m² (média: 23,2). Conforme critérios do CDC, 8 por cento dos pacientes (três meninas e três meninos) apresentavam obesidade e 8 por cento (duas meninas e quatro meninos), sobrepeso. CONCLUSÕES: Nesta casuística de pacientes diabéticos, a prevalência de sobrepeso e obesidade não se mostrou diferente de populações não diabéticas.

OBJECTIVE: To describe the prevalence of obesity according to gender and age in patients with type 1 diabetes mellitus of a pediatric endocrinology follow-up clinic. METHODS: This cross-sectional descriptive study enrolled patients of the follow-up clinic of the Pediatric Endocrinology Unit of Hospital de Base of São José do Rio Preto, São Paulo, Brazil. The following data were collected: gender, age, insulin dosage, glycated hemoglobin (HbA1c), weight, height and body mass index (BMI). The cutoff criteria for overweight and obesity were based on BMI-for-age growth charts of the Centers for Disease Control and Prevention (CDC, 2000). RESULTS: 77 patients with type 1 diabetes mellitus were included (44 females and 33 males), with three to 18 years old (mean: 13.4). The value of HbA1c varied from 4.1 to 10.6 percent (mean: 7.7 percent) and the BMI ranged from 15.1 to 28.6 kg/m² (average: 23.2). Based on BMI charts, 8 percent (three girls and three boys) were obese and 8 percent (two girls and four boys) had overweight. CONCLUSION: Compared to the prevalence of obesity and overweight in non-diabetic pediatric population, the presence of these nutritional disturbances in the studied children was not significantly different.
