Debut de diabetes tipo 1 en niños durante la pandemia Covid-19 en el Hospital de Pediatría Juan P. Garrahan / Debut of type-1 diabetes in children during the COVID-19 pandemic at Hospital de Pediatría Juan P. Garrahan

Introducción: Según numerosos reportes, la pandemia por COVID­19 aumentó la incidencia de diabetes tipo 1 (DBT1) y cetoacidosis (CAD). Nuestro objetivo fue describir la frecuencia de nuevos casos de DBT1 y su severidad al ingreso en el Hospital J. P. Garrahan durante la pandemia, comparando con el periodo anterior. Material y métodos: Se realizó un estudio descriptivo, observacional, con análisis retrospectivo. Se incluyeron todos los nuevos casos entre 19/03/20- 31/12/21, comparados con el período 19/03/18-31/12/19. El diagnóstico de DBT1, CAD y su severidad se realizó según la International Society for Pediatric and Adolescent Diabetes. Se analizó el requerimiento de cuidados intensivos (UCI), presencia de COVID-19, hemoglobina glicosilada A1C (HbA1C) y autoanticuerpos (GADA, IAA, IA2, ZNT8). Se consideró significativa una p < 0,05. Resultados: En el período 2020-2021 se observó un incremento del 107% de nuevos casos, ingresando 56 pacientes con DBT1. La media y mediana de edad disminuyeron (8 vs 9,1 y 7,7 vs 10,4, respectivamente), con un incremento del 35% de menores de 5 años. Aumentó la frecuencia de CAD severa (41.1% vs 25.9%) y de requerimiento de UCI (17.9% vs 11.1%). La Hb A1C y la glucemia de ingreso mostraron incremento significativo (10.1% vs 12.32%, p<0.003 y 580 mg/dl ± 220 vs 490 mg/dl ± 188; p<0.05, respectivamente). Conclusión: En 2020-2021 se incrementó el número de nuevos casos de DBT1 en nuestra institución. Al ingreso hubo mayor proporción de niños pequeños y casos severos. Las dificultades de acceso a la consulta de atención primaria podrían relacionarse con nuestro hallazgo (AU)

Introduction: Numerous reports have shown that during the COVID-19 pandemic the incidence of type-1 diabetes (T1DB) and ketoacidosis (DKA) increased. The aim of this study was to describe the frequency of new cases and their severity on admission of T1DB at Hospital J. P. Garrahan during the pandemic, compared with the previous period. Material and methods: A descriptive, observational study with a retrospective analysis was conducted. All new cases seen between 19/03/20-31/12/21 were included and compared with the period 19/03/18-31/12/19. The diagnosis of T1DB, DKA, and its severity was made according to the International Society for Pediatric and Adolescent Diabetes. Intensive care (ICU) requirement, presence of COVID-19, glycosylated hemoglobin A1C (HbA1C), and autoantibodies (GADA, IAA, IA2, ZNT8) were analyzed. A p < 0.05 was considered significant. Results: In the period 2020-2021, a 107% increase in new cases was observed including 56 patients with T1DB. Mean and median age decreased (8 vs 9.1 and 7.7 vs 10.4, respectively), with a 35% increase in children under 5 years of age. The frequency of severe DKA (41.1% vs 25.9%) and ICU requirement (17.9% vs 11.1%) increased. Hb A1C and glycemia on admission also showed a significant increase (10.1% vs 12.32%, p<0.003 and 580 mg/dl ± 220 vs 490 mg/dl ± 188; p<0.05, respectively). Conclusion: In 2020-2021 an increase in the number of new cases of T1DB was observed at our institution. On admission, a higher rate of young children and severe cases was found. Difficulties to access primary care may have been related to our finding (AU)

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.

Marcadores inmunológicos de diabetes tipo 1: análisis de 4.164 perfiles en un centro de salud de Chile / Analysis of 4, 164 type 1 diabetes antibody profiles in a Chilean health centre

Background: Previous studies have assessed the role of Type 1 diabetes (DM1) antibodies as predictors of the natural history of disease. Aim: To determine the frequency and combinations of positivity for DM1 antibodies in patients with DM1 and the relationship between antibody positivity and the age of the patient. To explore the relationship between history of insulin therapy or diabetic ketoacidosis (DKA) at the onset of the disease with antibody positivity in a subsample. Material and Methods: Data was gathered from every sample processed for DM1 antibodies in our laboratory between January 2015 and September 2019. Medical records from 84 patients who tested positive for at least one antibody were revised to study the relationship between insulin therapy or DKA at the onset of the disease with antibody positivity. Results: Forty percent of DM1 antibody tests were positive. Among positive tests, 1, 2, 3 or 4 DM1 antibodies were detected in 48%, 33%, 17% and 3% of cases, respectively. The likelihood of testing positive was inversely related with age for ICA, GAD, IA-2, ZnT8 and directlyproportionalforIAA (p= −0,012; −0,013; −0,014; −0,009; 0,005 respectively). An association between DKA at the onset of the disease and IA-2 positivity was observed (Odds ratio (OR) 5.38 95% confidence intervals (CI) 1.79 − 16.16, P < 0.01). No association was found between IAA positivity and history of insulin therapy (OR 2.25 95%CI 0.63 − 7.90, P = 0.2403). The results obtained from this study represent a novel local profile of DM1 antibody data, highlighting a relationship between antibody positivity and age.

Incidence, characteristics and long-term outcomes of patients with diabetic ketoacidosis: a prospective prognosis cohort study in an emergency department

ABSTRACT BACKGROUND: Diabetic ketoacidosis is the most frequent hyperglycemic complication in the evolution of diabetes mellitus. Common precipitating factors include newly diagnosed diabetes mellitus, noncompliance with therapy and infections. However, few studies have been conducted in Brazil and none were prospective in design. OBJECTIVE: To describe the incidence, clinical and laboratory characteristics and precipitating factors of diabetic ketoacidosis among emergency department patients in a tertiary-level teaching hospital in Brazil. We also aimed to identify immediate and long-term mortality within two years. DESIGN AND SETTING: Prospective prognosis cohort study conduct at a tertiary-level teaching hospital in São Paulo, Brazil. METHODS: All patients > 12 years old presenting diabetic ketoacidosis who were admitted to the emergency department from June 2015 to May 2016 were invited to participate. RESULTS: The incidence of diabetic ketoacidosis per 1,000 admissions was 8.7. Treatment noncompliance and infection were the most common causes of diabetic ketoacidosis. The immediate mortality rate was 5.8%, while the six-month, one-year and two-year mortality rates were 9.6%, 13.5% and 19.2%, respectively. Death occurring within two years was associated with age, type 2 diabetes, hypoalbuminemia, infection at presentation and higher sequential organ failure assessment (SOFA) score at admission. CONCLUSIONS: Diabetic ketoacidosis among patients presenting to the emergency department was relatively frequent in our hospital. Treatment noncompliance and infection were major precipitating factors and presence of diabetic ketoacidosis was associated with immediate and long-term risk of death.

Diabetic ketoacidosis as the initial presentation of type 1 diabetes in children and adolescents: epidemiological study in southern brazil / Cetoacidose diabética como apresentação inicial de diabetes tipo 1 em crianças e adolescentes: estudo epidemiológico no sul do brasil

ABSTRACT Objective: To analyze the variables associated with the presence of diabetic ketoacidosis in type 1 diabetes mellitus (T1DM) diagnosis and its impact on the progression of the disease. Methods: We reviewed the records of 274 children and adolescents under 15 years, followed in a Pediatric Endocrinology clinic of a university hospital in Curitiba-PR. They had their first appointment between January 2005 and April 2015. Results: Most patients received their T1DM diagnosis during a diabetic ketoacidosis episode. The associated factors were: lower age and greater number of visits to a physician's office prior to diagnosis; diabetic ketoacidosis was less frequent in patients who had siblings with T1DM and those diagnosed at the first appointment. Nausea and vomiting, abdominal pain, tachydyspnea, and altered level of consciousness were more common in the diabetic ketoacidosis group. There was no association with socioeconomic status, duration of symptoms before diagnosis, and length of the honeymoon period. Conclusions: Prospective studies are necessary to better define the impact of these factors on diagnosis and disease control. Campaigns to raise awareness among health professionals and the general population are essential to promote early diagnosis and proper treatment of diabetes mellitus in children and adolescents.

RESUMO Objetivo: Avaliar as variáveis associadas ao diagnóstico de diabetes melito tipo 1 (DM1) na vigência de cetoacidose diabética e seu impacto na evolução da doença. Métodos: Foram avaliadas 274 crianças e adolescentes com idade até 15 anos acompanhados em um ambulatório de endocrinologia pediátrica de um hospital universitário de Curitiba, Paraná, cuja primeira consulta ocorreu entre janeiro de 2005 e abril de 2015. Resultados: A maioria dos pacientes teve diagnóstico de DM1 na vigência de cetoacidose diabética. Os fatores associados foram: menor idade e maior número de consultas prévias ao diagnóstico; a cetoacidose diabética foi menos frequente quando havia um irmão com DM1 e quando o diagnóstico foi feito na primeira consulta médica. Náuseas ou vômitos, dor abdominal, taquidispneia e alteração do nível de consciência foram mais frequentes no grupo com cetoacidose diabética ao diagnóstico. Não se observou associação com nível socioeconômico, tempo de sintomas antes do diagnóstico e duração do período de lua de mel. Conclusões: São necessários estudos prospectivos para definir melhor o impacto desses fatores no diagnóstico e no controle da doença. Campanhas de conscientização dos profissionais de saúde e da população são necessárias para que haja diagnóstico precoce e tratamento adequado do diabetes melito em crianças e adolescentes.

Estudio descriptivo de las cetoacidosis atendidas en urgencias de un hospital de la Comunidad de Madrid mediante la herramienta Savana Manager / Diabetic ketoacidosis in a emergency department of a hospital in Madrid (Spain) using the Savana Manager tool

Objetivo: El objetivo del estudio fue describir las características y evolución de los pacientes que acudieron a las urgencias de nuestro hospital y fueron diagnosticados de cetoacidosis diabética (CAD) utilizando la novedosa herramienta de Big Data Savana. Método: Estudio retrospectivo descriptivo de los pacientes atendidos en urgencias del Hospital Universitario Infanta Leonor durante los años 2011 al 2016 con diagnóstico de CAD. La búsqueda se realizó con Savana Manager. Resultados: Se diagnosticaron 95 episodios de CAD en 68 pacientes. Del total de episodios de CAD, 57 fueron en diabéticos tipo 1 (de ellos 4 LADA), 25 en diabéticos tipo 2, 2 en diabéticos postpancreatectomía y 12 fueron debuts diabéticos. Del total, 61 (64,2%) requirieron ingreso hospitalario, de ellos 23 (24,2%) ingresaron en UCI. La media de HbA1c fue de 10,6 ± 2,1%. Tres pacientes requirieron reingreso tras el alta. La mortalidad fue muy baja con el fallecimiento en 1 paciente diagnosticado simultáneamente de cáncer pulmonar. Los desencadenantes de la CAD fueron: 35 casos (36,8%) falta de adherencia al tratamiento, 31 (32,6%) infecciones, 12 (12,6%) debuts, 8 (8,4%) varias causas y 9 (9,5%) no se pudo determinar la causa. Se clasificaron como CAD de gravedad leve un 28%, un 38% como de gravedad moderada y 34% como graves. La duración del ingreso no se relacionó con la severidad de la cetoacidosis. Conclusiones: La CAD es una complicación grave que afecta tanto a diabéticos tipo 1 como a tipo 2 con elevado porcentaje de ingresos hospitalarios y en UCI, aunque con baja mortalidad en nuestro medio. La duración de los ingresos no se relaciona con la severidad del cuadro.

Objective: the study was designed to describe the clinical features and evolution of the diabetic patients attended in our hospital emergency department with diabetic ketoacidosis (DKA) using the novel Big Data tool Savana. Method: Retrospective descriptive study of the patients attended in the emergency room of the Infanta Leonor University Hospital during the years 2011 to 2016 with diagnosis of CAD. The search was made with Savana. Results: 95 episodes of DKA were diagnosed in 68 patients. Of the total episodes of CAD 57 were in type 1 diabetics (of which 4 were LADA), 25 in type 2 diabetics, 2 in diabetics postpancreatectomy and 12 were new onset of diabetes. Of the total, 61 (64.2%) required hospital admission, of which 23 (24.2%) were admitted to the intensive care unit (ICU). The mean HbA1c was 10.6 ± 2.1%. Three patients required readmission after discharge. Mortality was very low with death in 1 patient simultaneously diagnosed of lung cancer. The triggers of CAD were: 35 cases (36,8%) lack of adherence to treatment, 31 (32.6%) infections, 12 (12.6%) new onset, 8 (8,4%) various causes and 9 (9.5%) the cause could not be determined. They were classified as mild DKA 28%, 38% as moderate and 34% as severe. The duration of admission was not related to the severity of ketoacidosis. Conclusions: DKA is a serious complication that affects both, type 1 and type 2 diabetics patients, with a high percentage of hospital and ICU admissions, although with low mortality in our environment. The lenght of the stay in hospital is not related to the severity of the DKA.

Profils épidémiologiques des acidocétoses diabètiques aux urgences

Introduction: l'acidocétose diabétique (ACD) est une complication métabolique grave du diabète. Son incidence est en augmentation ces dernières années, cependant sa mortalité reste faible. L'objectif de cette étude a été de décrire les caractéristiques épidémiologiques, cliniques, thérapeutiques et pronostiques des patients admis aux urgences pour ACD sévère ou modérée. Méthodes: il s'agissait d'une étude prospective, descriptive qui a inclus les ACD modérée ou sévère. Standardisation du protocole de prise en charge thérapeutique. Nous avons étudié les caractéristiques épidémiologiques, cliniques, thérapeutiques et pronostiques chez ces patients. Résultats: nous avons inclus 185 patients avec ACD sévère ou modérée. L'âge moyen a été de 38±18 ans; le sexe ratio=0,94. Diabète connue= 159 patients (85%) dont 116 étaient des diabétiques type 1. Les facteurs de décompensation les plus fréquents étaient l'arrêt du traitement chez 42% et l'infection chez 32%. La glycémie moyenne a été de 32,7±12mmol/L, pH =7,14±0,13, HCO-3 =7,2±3,56 mmol /L. La durée moyenne de l'insuline intraveineuse était de 17,3±16 heures. L'hypoglycémie a été observée chez 26 patients (14%), l'hypokaliémie chez 80 (43%). La mortalité au cours de l'hospitalisation a été de 2,1%. Conclusion: l'acidocétose diabétique survient chez les sujets jeunes traités par insulinothérapie. Le traitement est à base d'insuline par voie intraveineuse en plus de la correction du déficit hydrique. Les complications sont essentiellement l'hypokaliémie et l'hypoglycémie; et la mortalité reste faible

Prevalence of markers of celiac disease in Colombian children with diabetes mellitus type 1 / Prevalencia de marcadores de enfermedad celíaca en niños Colombianos con diabetes mellitus tipo 1

Abstract Introduction: Although the association between diabetes mellitus type 1 (T1DM) and celiac disease (CD) is well established; there are only a few studies that focus on South American children, haplotypes and their possible associations. Objective: To determine the prevalence of CD markers in a group of children with T1DM and to analyze the associated clinical, immunological and genetic manifestations. Methods: A prevalence study focusing on children with T1DM who were assessed based on variables including sociodemographics, anthropometric information, disease characteristics, laboratory results and family medical history. In partitipants a positive tTG2 (Ig A anti-transglutaminase), a duodenal biopsy and genotype were performed. The proportion of children with T1DM and CD was estimated (CI 95%). Determinations of central tendency, univariate and bivariate analysis, were also performed; p <0.05 was considered significant. Results: Thirteen (8.4%) of the 155 children (53.6% girls, 11.0 ±3.6 years, 2-18 years) with T1DM were tTG2 positive, four had CD (2.6%), seven had potential CD (4.5%) and nine were HLA DQ2/DQ8 positive (5.8%). Children with T1DM and CD had their last ketoacidotic episode (21.5 ±30.4 months versus 69.5 ±38.8 months, p= 0.0260) earlier than children with T1DM and potential CD. There were no differences with anthropometry or with the laboratory results regarding glycemic control. Conclusions: The prevalence of CD in these children with T1DM is higher than that reported in other South American countries. The prevalence of CD was found to be associated with the time of presentation of T1DM and its main allele, the DQ2/DQ8. These findings are different from what has been described in other places around the world.

Resumen Introducción: A pesar que la asociación entre diabetes mellitus tipo 1 (DMT1) y enfermedad celíaca (EC) está bien establecida; hay pocos estudios en niños suramericanos sobre haplotipos y sus posibles asociaciones. Objetivo: Determinar la prevalencia de marcadores de EC en un grupo de niños con DMT1, analizando las manifestaciones clínicas, inmunológicas y genéticas. Métodos: Estudio de prevalencia en niños con DMT1 a quienes se les tomaron variables sociodemográficas, antropométricas, de la enfermedad, paraclínicas y familiares metabólicas. A los niños con IgA anti-transglutaminasa (tTG2) positivos, se les realizó biopsia duodenal y genotipo. Se estimó la proporción de niños con DMT1 y EC y su IC 95%; medidas de tendencia central, análisis univariado y bivariado, siendo significativa una p <0.05. Resultados: Trece (8.4%) de los 155 niños (53.6% niñas, de 11.0 ±3.6 años, 2-18 años) con DMT1 fueron tTG2 positivos, cuatro presentaron EC (2.6%), siete EC potencial (4.5%) y nueve HLA DQ2/DQ8 (5.8%). Los niños con DMT1 y EC presentaron más pronto su último episodio cetoacidótico (21.5 ±30.4 meses versus 69.5 ±38.8 meses, p= 0.0260) que los niños con DMT1 y EC potencial. No hubo diferencias con la antropometría ni con los paraclínicos del control glicémico. Conclusiones: La prevalencia de EC en estos niños con DMT1 es superior a la de otros países suramericanos; estando asociada al tiempo de presentación de la DMT1 y su principal alelo el DQ2/DQ8, hallazgos diferentes a lo descrito a nivel mundial.

Complicaciones agudas de la Diabetes mellitus, visión práctica para el médico en urgencias: Revisión de tema / Acute complications of diabetes mellitus, practical vision for the emergency physician: Review

La Diabetes Mellitus (DM) representa una de las Enfermedades Crónicas No Transmisibles (ECNT) más prevalentes del mundo, cuyas complicaciones agudas o emergencias hiperglucémicas más importantes, en el escenario de la medicina de urgencias, son la Cetoacidosis Diabética (CAD), el Estado Hiperglucémico Hiperosmolar (EHH) y la Hipoglucemia, todas ellas asociadas a un control inadecuado o insuficiente de la enfermedad. Con el objetivo de mejorar eficazmente la condición clínica de los pacientes que presentan algún tipo de emergencia hiperglucémica, los médicos del servicio de urgencias deben tener claridad en diversos aspectos clave relacionados con la fisiopatología y el abordaje apropiado para cada situación. En este artículo se reúne la información más actualizada respecto a la definición, epidemiología, etiopatogenia, manifestaciones clínicas, diagnóstico, tratamiento y prevención, de las tres complicaciones agudas de la DM, a fin de ofrecer al clínico una guía práctica para el abordaje y manejo adecuado de los pacientes diabéticos en el contexto de las emergencias hiperglucémicas.

Diabetes Mellitus (DM) represents one of the most prevalent Chronic Noncommunicable Diseases (NCDs) in the world, which acute complications or major hyperglycemic emergencies, in the scenario of emergency medicine, are Diabetic Ketoacidosis (DKA), the State Hyperosmolar hyperglycemic (EHH) and Hypoglycaemia, all associated with inadequate or insufficient control of the disease. In order to effectively improve the clinical condition of patients presenting with some type of hyperglycaemic emergency, emergency department physicians should be clear about various key aspects related to the pathophysiology and the appropriate approach for each situation. This article gathers the most up-to-date information regarding the definition, epidemiology, etiopathogenesis, clinical manifestations, diagnosis, treatment and prevention of the three acute complications of DM mentioned above, in order to offer the clinician a practical guide for the approach and proper management of diabetic patients in the context of hyperglycemic emergencies.

Objetivos: Conocer las características clínicas, epidemiológicas (sexo, edad, antecedentes, factores desencadenantes) y las diferencias del tratamiento con insulina endovenosa vs intramuscular en los pacientes con diagnóstico de CAD (cetoacidosis) que ingresaron en el servicio de emergencia del Hospital Nacional Daniel Alcides Carrión durante el periodo Agosto 2005-Mayo 2012. Material y métodos: Se realizó un estudio observacional, analítico, retrospectivo y transversal. Se revisaron 51 historias clínicas de pacientes con diagnóstico de CAD que ingresaron en el periodo de tiempo del estudio. Resultados: la media de la edad de los pacientes fue 46.01+/-14.5 años. El 58.8 por ciento de los pacientes fueron del sexo femenino. El 35.3 por ciento debutaban con un episodio de cetoacidosis diabética. La medicación más frecuente que recibían los pacientes eran los hipoglicemiantes orales en un 35.3 por ciento de los casos. El 47.1 por ciento de los pacientes eran obesos. EL 47.1 por ciento de los pacientes tenían el antecedente de diabetes. El 35.3 por ciento de los pacientes tuvieron poliuria como síntoma más frecuente. El 23.5 por ciento de los pacientes presentaron somnolencia. El 62.7 por ciento de los pacientes abandonaron el tratamiento. El 58.8 por ciento de los pacientes recibieron insulina por infusión continua y el 41.2 por ciento recibieron insulina por dosis horaria intramuscular. La complicación más frecuente fue la hipoglicemia que se presentó en el 45.1 por ciento de los casos. Conclusiones: La infusión continua fue más usada en los pacientes del sexo femenino (73.3 por ciento), y las dosis horarias fueron usadas con mayor frecuencia en el sexo masculino (61.9 por ciento) (P<0.05). La insulina horaria fue más usada en pacientes obesos (76.2 por ciento) (P<0.05). Hubo una diferencia estadísticamente significativa entorno al PH, potasio final y menor tiempo de hospitalización con la insulina por infusión continua, y menor dosis de insulina con las...

The Clinical Measures Associated with C-peptide Decline in Patients with Type 1 Diabetes over 15 Years

This study was done to characterize the natural course of C-peptide levels in patients with type 1 diabetes and identify distinguishing characters among patients with lower rates of C-peptide decline. A sample of 95 children with type 1 diabetes was analyzed to retrospectively track serum levels of C-peptide, HbA1c, weight, BMI, and diabetic complications for the 15 yr after diagnosis. The clinical characteristics were compared between the patients with low and high C-peptide levels, respectively. The average C-peptide level among all patients was significantly reduced five years after diagnosis (P < 0.001). The incidence of diabetic ketoacidosis was significantly lower among the patients with high levels of C-peptide (P = 0.038). The body weight and BMI standard deviation scores (SDS) 15 yr after diagnosis were significantly higher among the patients with low C-peptide levels (weight SDS, P = 0.012; BMI SDS, P = 0.044). In conclusion, C-peptide level was significantly decreased after 5 yr from diagnosis. Type 1 diabetes patients whose beta-cell functions were preserved might have low incidence of diabetic ketoacidosis. The declines of C-peptide level after diagnosis in type 1 diabetes may be associated with changes of body weight and BMI.

Pattern of presentation in type 1 diabetic patients at the diabetes center of a university hospital

Diabetes mellitus [DM] is a major health problem worldwide. This study aimed to investigate the pattern of presentation and complications of pediatric diabetes. Retrospective study of children treated at a diabetes clinic at a university hospital for diabetes over 12-year period. We collected data on the age at onset, sex, clinical presentation, duration of symptoms before diagnosis, and partial remission rate that were obtained from the hospital medical records, the National Diabetes Registry, and the statistics department. Of 369 diabetic children, most [n=321] children had polyuria [92%] 321/369=87% as the presenting symptom; other symptoms included polydipsia [310 patients, 88.8% 310/369=84%], weight loss [292 patients, 83.9%], nocturia [240 patients, 68.8% 240/369=65%], diabetic ketoacidosis [DKA] [174 patients, 49.9% 174/369=47.20%], and abdominal pain [172 patients, 49.3% 174/369=46.6%]. Presenting symptoms were missing in 20 files, so the percentages were calculated among 349 patients. Most patients had acute diabetic complications such as hypoglycemia [222 patients, 62%] and DKA [88 patients, 38.1%, but none had severe complications such as coma and cerebral edema. Chronic complications included retinopathy [4 patients, 1.3%], neuropathy [2 patients, 0.6%], coronary heart disease [2 patients, 0.6%], and nephropathy [1 patient, 0.4%]. The pattern of presentation of type 1 diabetes has changed as the incidence of DKA has decreased; unlike in previous studies, DKA was not the most common presenting symptom in this study. Chronic complications of diabetes, such as retinopathy, neuropathy, coronary heart disease, and nephropathy are mostly rare but still present. These complications might be prevented by achieving better awareness of the need for glycemic control

Cetoacidosis diabética en adultos: causas y su manejo en un hospital regional / Management of diabetic ketoacidosis: retrospective analysis of 117 episodes

Background: In 2005, the Chilean Ministry of Health developed Clinical Guidelines to ensure the correct diagnosis and acute treatment of diabetic ketoacidosis (DKA). Aim: To analyze the real impact of the use of the Clinical Guidelines, comparing the diagnosis and treatment of DKA beforeand after 2005. Patients and Methods: Retrospective analysis of clinical records of adults with DKA, treated between 2001 and 2008 in a regional hospital. Results: One hundred seventeen DKA episodes, that occurred in 82 patients aged 15 to 90 years (47 percent females), were analyzed. Eightytwo percent of patients were known diabetics. Treatment discontinuation was the cause of DKA in 37 percent of patients, followed by infections in 37 percent and onset of diabetes mellitus in 17 percent. Ninety seven percent of patients previous episode of DKA were using insulin. Two patients died (1.7 percent) and DKA complications were uncommon. Bicarbonate and potassium were over prescribed despite therecommendation of Clinical Guidelines (p < 0.05). The use of infusion pumps increased after the incorporation of the Clinical Guidelines. Conclusions: A low impact of Clinical Guidelines on themanagement of DKA was observed in this group of patients. Insulin users have a higher risk for developing DKA.

The found symptoms most common in the admission had been vomits, polidipsia, poliúria. Blood gasanalisys was carried through in 15 of 22 cases, being 11 diabetic positive for cetoacidose. The average age of diagnosis was of 7,5 years. Great part of the patients more than had an internment related with diabetes duringthe period of the sample. Conclusion: Diabetes is a cronical disease that needna adequate glicemic control to prevent complications and is necessary an early diagnosis and treatment to improve quality of life of this patient.

Type 1 diabetes mellitus with ketoacidosis in infancy.

Type 1 diabetes mellitus is considered a common form of diabetes mellitus in young people. Type 1 diabetes in infants is rare. However, the condition is rare in infants. Type 1 diabetes has not been reported in the literature in 45 days old child of an Indian population. Type 1 diabetes typically begins between the ages of 7 and 13 years, but 1-3% of patients are under 1 year of age. This communication describes a case of type 1 diabetes in a 45 days old male child which presented as diabetic ketoacidosis. It was effectively managed with continuous intravenous regular insulin infusion. The present report is made because of the rarity of the condition in the early age group of Indian children.

Maternal and neonatal metabolic complications in cases of gestational diabetes about 220 cases

We report a retrospective study of 220 cases of gestational diabetes collected during a 5 year period [2001-2006]. Hypoglycemia was the most frequent maternal metabolic complication [11%], whereas ketoacidosis was rare, seen in only two patients [0.8%]. Neonatal metabolic complications were mostly hypoglycemia [19%] and hypocalcaemia [7%]. Pregnancy in diabetic women involves more risks than pregnancy in non-diabetic women. However, these risks are now better controlled

Diabetes en el senescente / Diabetes in the senescent

La diabetes mellitus (DM) en el senescente muestra un notable aumento de prevalencia, 15 a 18 por ciento actualmente, constituyendo un problema de salud pública por las complicaciones crónicas que la acompañan, las que determinan una menor expectativa y calidad de vida. Su escasa sintomatología hace que el diagnóstico se haga generalmente por exámenes de rutina, por complicaciones de la enfermedad o en un coma hiperosmolar, de allí la necesidad de pesquisar la DM en las etapas precoces. La DM del adulto mayor corresponde generalmente a una diabetes tipo 2. El tratamiento de la DM en el senescente no difiere sustancialmente del efectuado en sujetos más jóvenes, pero en más del 50 por ciento la DM se controla con medidas no farmacológicas. Cuando se requiere el uso de drogas orales, deben emplearse las de más baja potencia- preferentemente tolbutamida o gliclazida- en las dosis mínimas necesarias, a objeto de no provocar hipoglicemias, las que suelen ser severas e incluso mortales. Pueden presentar complicaciones agudas metabólicas, coma hiperosmolar no cetósico con mayor frecuencia y, en forma excepcional, cetoacidosis diabética grave, ambos cuadros de elevada mortalidad en estos pacientes. La hipoglicemia es la complicación aguda más relevante, la que debe prevenirse con un adecuado tratamiento y controles periódicos. Las complicaciones crónicas micro y macrovasculares son de alta prevalencia, así como las patologías asociadas. De allí que estos pacientes requieren de una atención integral

Hidratacion en la cetoacidosis diabetica. ¿Como influye la velocid de infusion / Hydration in diabetic ketoacidosis. How much influence does the rate of infusion have?

La cetoacidosis diabética (CAD) se acompaña de severa depleción hidroelectrolítica; aunque habitualmente se utiliza hidratación abundante, el ritmo de reposición de fluidos en esta patología continúa siendo controvertido. A fin de determinar la velocidad de infusión de líquidos adecuada en la CAD sin patología asociada, se realizó un estudio prospectivo, randomizado, en 27 pacientes sometidos a dos planes terapéuticos diferentes sólo en el ritmo del aporte de líquidos. Un grupo (14 pacientes) recibió solución salina al 0,9 por ciento a una velocidad de 1000 ml/h, y otro grupo (13 pacientes) a 500 ml/h; el flujo de reposición hidrosalina se redujo a la mitad después de 4 horas de tratamiento. Al ingreso y a las 2, 4, 8, 12 y 24 horas se realizaron determinaciones del estado ácido-base en sangre arterial, y de sodio, potasio y cloro en plasma. Ambos grupos fueron similares en las determinaciones bioquímicas al ingreso. Todos los pacientes corrigieron el cuadro de cetoacidosis y no se observó mortalidad ni complicaciones. No se hallaron diferencias significativas para ninguna de las variables metabólicas entre los grupos de tratamiento en ningún momento de la evolución. Se concluye que resulta igualmente efectivo utilizar una velocidad de reposición de líquidos de 500 ml/h que de 1000 ml/h, en cuanto a la morbimortalidad de los pacientes con CAD no asociada a severa depleción de volumen. El uso de cantidades modestas de fluidos para la hidratación en estos pacientes resultaría en menores costos.
