RESUMO

BACKGROUND: Although the importance of walking for promoting a better cardiometabolic health is widely known (this includes both cardiovascular and metabolic/endocrine systems), there is little knowledge regarding its appropriate pace to provide adults with more cardiometabolic benefits. AIM: To analyze the associations between different walking pace categories and cardiometabolic health markers in the adult Chilean population. METHODS: Cross-sectional study. A total of 5520 participants aged 15 to 90 years old from the Chilean National Health Survey (CNHS) 2016-2017 were included. Walking pace categories (slow, average, and brisk) were collected through self-reported methods. Glycaemia, glycosylated hemoglobin (HbA1c), gamma glutamyl transferase (GGT), vitamin D2, vitamin D3, systolic and diastolic blood pressure, and lipid profile (Total, HDL, LDL, VLDL, No HDL cholesterol and triglycerides) were determined using blood sample tests and measured with the standardized methods described in the CNHS 2016-2017. RESULTS: People who had a brisk walking pace were associated with lower levels of glycaemia, HbA1c, GGT, systolic and diastolic blood pressure, and higher vitamin D3 levels compared with those with a slow walking pace. Moreover, people with a brisk walking pace had lower levels of VLDL cholesterol compared with those with a slow walking pace. However, after adjusting the model to include sociodemographic background, nutritional status, and lifestyle variables, the differences remained only for glycaemia, HbA1c and systolic blood pressure levels. CONCLUSIONS: A brisk walking pace was associated with better cardiometabolic health markers and lipid profile compared with a slow walking pace.

RESUMO

Introducción: La retinopatía diabética es la principal causa de ceguera en personas diabéticas de 20 a 64 años de edad, e incrementa su aparición frente a un mal control de la enfermedad, que se expresa con valores altos de hemoglobina glucosilada (HbA1C). Objetivo: Establecer la relación entre los niveles de hemoglobina glucosilada y la presencia de retinopatía en los pacientes con diabetes mellitus tipo 2. Métodos: Se llevó a cabo un estudio descriptivo, prospectivo y transversal, en el que se obtuvieron, mediante ficha de observación, datos sociodemográficos, de evaluación oftalmológica y niveles de HbA1C, de los pacientes atendidos en consulta externa del Hospital General Isidro Ayora de la ciudad de Loja, Ecuador, en el período febrero-junio de 2018. Se aplicaron medidas de frecuencia y asociación para el análisis estadístico. Resultados: Se incluyeron 160 pacientes: 108 mujeres y 52 hombres, todos de raza mestiza. Se identificó retinopatía en 26,8 por ciento (N = 43) de los pacientes, de quienes 41 por ciento (N = 18) tenía más de 65 años de edad. La media de HbA1C en pacientes sin retinopatía fue de 7,4 por ciento, y en aquellos con retinopatía de 9,8 por ciento en mayor porcentaje de pacientes con valores de HbA1C de 7 por ciento o más presentaron retinopatía diabética, en comparación con aquellos de HbA1C menores a 7 por ciento (p < 0,0001), la retinopatía no proliferativa moderada fue el principal diagnóstico realizado. Conclusiones: El mal control glucémico en las personas con diabetes mellitus tipo 2 se asocia con mayor probabilidad de aparición de lesiones retinianas(AU)

Introduction: Diabetic retinopathy is the main cause of blindness in diabetic people aged 20 to 64 years; it increases its occurrence due to poor control of the disease, expressed by high values of glycosylated hemoglobin (HbA1c). Objective: To establish the relationship between glycosylated hemoglobin levels and the presence of retinopathy in patients with type 2 diabetes mellitus. Methods: A descriptive, prospective and cross-sectional study was carried out, in which sociodemographic data, others from an ophthalmologic evaluation and HbA1c levels were obtained, by means of an observation card, from patients seen in the outpatient clinic of Hospital General Isidro Ayoraof the city of Loja, Ecuador, in the period February-June 2018. Frequency and association measures were applied for statistical analysis. Results: The study included 160 patients: 108 women and 52 men, all of mixed race. Retinopathy was identified in 26.8percent (N=43) of patients, of whom 41percent (N=18) were over 65 years of age. The mean HbA1c in patients without retinopathy was 7.4percent, and 9.8percent in those with retinopathy. A higher percentage of patients with HbA1c values of 7percent more had diabetic retinopathy, compared to those with HbA1C under 7percent (p<0.0001). Moderate nonproliferative retinopathy was the main diagnosis. Conclusions: Poor glycemic control in persons with type 2 diabetes mellitus is associated with increased likelihood of retinal lesions(AU)

RESUMO

Abstract Objective: To assess whether depression and quality of life scores correlate with glycosylated hemoglobin A (HbA1c) levels in type 2 diabetes mellitus (T2DM) patients of predominant Mayan ethnicity, from a rural community in the state of Yucatán, Mexico. Materials and methods: Instruments: for depression, CES-D (cutoff ≥ 16); for quality of life, D-39; criterion for poor glycemic control, HbA1c ≥ 8%. Results: Depression was detected in 36.3% of 33 diabetic subjects (10 men, 23 women), and their HbA1c levels (mean ± SD) were higher (10.7 ± 2.5%) than for those without depression (8.6 ± 2.2%, p = 0.015; unpaired Student's t-test, two-tailed). Depression occurred in 33.3% of diabetics with HbA1c ≥8%, but only in 3.0% of those with HbA1c < 8% (p = 0.027, Fisher's exact test). HbA1c levels positively correlated with CES-D scores (r2 =0.135; p = 0.035; Pearson). D-39 "Anxiety-Worry" (AW) dimension scores were higher in diabetics with depression (43.3 ± 22.2) than in those without depression (17.7 ± 17.8; p = 0.005, Mann-Whitney U-test). A positive correlation was found between CES-D and AW scores (r2 = 0.304; p = 0.001; Pearson). Conclusions: Considering that depression and anxiety have been related to poor self-care for achieving a good glycemic control, we propose the concomitant use of CES-D and D-39, which are validated and easy-to-apply instruments, as screening tests to detect depression and anxiety in T2DM patients residing in rural communities. Therefore, if patients test positive on one or both instruments, they can be referred to a psychiatrist to confirm the diagnosis and provide appropriate therapy. This would help to promote adherence to diabetes control measures and improve their quality of life.

Resumen Objetivo: Evaluar si las puntuaciones de depresión y calidad de vida se correlacionan con los niveles de hemoglobina glucosilada (HbA1c) en pacientes con diabetes mellitus tipo 2 (DM2) de etnia maya predominante, de una comunidad rural en el estado de Yucatán, México. Materiales y Métodos: Instrumentos: para depresión, CES-D (punto de corte ≥ 16); para calidad de vida, D-39; criterio de mal control glucémico, HbA1c ≥ 8%. Resultados: Se detectó depresión en el 36.3% de 33 sujetos diabéticos (10 hombres, 23 mujeres), y sus niveles de HbA1c (media ± DE) fueron más altos (10.7 ± 2.5%) que para los que no tenían depresión (8.6 ± 2.2%, p = 0.015; prueba t de Student, no pareada). La depresión se presentó en el 33.3% de los diabéticos con HbA1c ≥ 8%, pero solo en el 3.0% de aquellos con HbA1c <8% (p = 0.027, prueba exacta de Fisher). Los niveles de HbA1c se correlacionaron positivamente con las puntuaciones CES-D (r2 = 0.135; p = 0.035; Pearson). Los puntajes de la dimensión "Ansiedad-Preocupación" (AW) del D-39 fueron más altos en diabéticos con depresión (43.3 ± 22.2) que en aquellos sin depresión (17.7 ± 17.8; p = 0.005, prueba U de Mann-Whitney). Se encontró una correlación positiva entre las puntuaciones CES-D y AW (r2 = 0.304; p = 0.001; Pearson). Conclusiones: Considerando que la depresión y la ansiedad han sido asociadas a autocuidados inadecuados para alcanzar un buen control glicémico, proponemos el uso concomitante de CES-D y D-39, que son instrumentos validados y de fácil aplicación, como pruebas de cribado para detectar depresión y ansiedad en pacientes con DM2 residentes en comunidades rurales. Por lo tanto, si los pacientes dan positivo en uno o ambos instrumentos, se les puede derivar a un psiquiatra para confirmar el diagnóstico y proporcionar la terapia adecuada. Esto ayudaría a promover el cumplimiento de las medidas de control de la diabetes y a mejorar su calidad de vida.

RESUMO

La diabetes es una enfermedad crónica que aparece cuando el páncreas no produce insulina suficiente o cuando el organismo no utiliza eficazmente la insulina que produce. La insulina es una hormona que regula el azúcar en la sangre. El efecto de la diabetes no controlada es la hiperglucemia (aumento del azúcar en la sangre), que con el tiempo daña gravemente muchos órganos y sistemas, especialmente los nervios y los vasos sanguíneos.

Diabetes is a chronic disease that appears when the pancreas does not produce enough insulin or when the body does not use the insulin it produces effectively. Insulin is a hormone that regulates blood sugar. The effect of uncontrolled diabetes is hyperglycemia (increased blood sugar), which over time severely damages many organs and systems, especially nerves and blood vessels.

RESUMO

La diabetes mellitus (DM) es una enfermedad crónica que se define por la hiperglucemia prolongada en el tiempo, que trae como consecuencia daño a nivel microangiopático - macrovascular y representa uno de los mayores problemas de salud pública a nivel mundial. Actualmente, no se ha podido definir en la población chilena los diferentes factores que influyen en la adherencia al tratamiento de los pacientes con DM2. Objetivo: Analizar la asociación entre la baja adherencia terapéutica en personas adultas con DM2 que se atienden en el CESFAM Jean et Marie Thierry y las variables propias del paciente como sexo, edad, presencia de otras enfermedades crónicas y polifarmacia. Materiales y métodos: Se realizó un estudio observacional y analítico de corte transversal, en pacientes con DM2 pertenecientes al CESFAM Jean et Marie Thierry en el año 2019 y 2020. Se recolectaron datos desde la cartola del programa cardiovascular, parte de la ficha clínica, correspondiente a cada paciente con DM2 del CESFAM. Resultados: Se obtuvieron datos de 253 participantes del CESFAM. En total, un 43,87% de los pacientes no fueron adherentes y un 56,13% fue adherente al tratamiento. El promedio de edad fue de 67,3 años y la adherencia en pacientes con enfermedades crónicas concomitantes 44,1%. Conclusión: No hubo una asociación significativa entre las variables estudiadas y la adherencia terapéutica. A pesar de esto, es importante continuar el estudio debido al gran número de pacientes diabéticos no adherentes a su tratamiento.

Diabetes mellitus (DM) is a chronic disease defined as hyperglycemia over a prolonged period leading to damage at the microangiopathic and macrovascular level and is one of the largest public health problems worldwide. Currently, it has not been possible to define the different factors influencing treatment adherence in DM2 patients in the Chilean population. Objectives: Analyze the association between adherence to treatment in adults with DM2 attending CESFAM Jean et Marie Thierry and the patients' variables such as gender, age, concomitant chronic disease and polypharmacy. Material and Methods: In 2019 and 2020 an observational and analytical study was done in a cross section of DM2 patients from CESFAM Jean y Marie Thierry. Data from each of the CESFAM's DM2 patients was collected from the cardiovascular program register in the clinical file. Results: Data was obtained from 253 participants. In total, 43.87% did not adhere to treatment and 56.13% adhered to treatment. The average age was 67.3 years and the adherence in patients with concomitant chronic disease was 44.1%. Conclusion: There was no significant association between the variables studied and adherence to treatment. Despite this, it is important to continue the study because of the large number of diabetics not adhering to treatment.

RESUMO

Objetivos: El estudio tuvo como objetivo identificar la presencia de bacilos negro pigmentantés (BNP) en bolsas periodontales de pacientes diabéticos tipo 2 y determinar una relación con su control glicémico. Material y métodos: Se evaluó un número total de 46 pacientes que cumplían con los criterio de inclusión en el estudio, de los cuales quedaron 20 por haber concluido con todas las pruebas realizadas en el estudio, como el estudio microbiológico de sus muestras de placa subgingival y las pruebas de hemoglobina glicosilada que se realizó en forma periódica en los 3 meses que se evaluó a los pacientes. Resultados: De los 20 pacientes evaluados que completaron todas sus pruebas, 14 eran mujeres y 6 varones, con un rango de edad de 40 a 68 años, pudiéndose identificar estos bacilos negro pigmentantés (BNP) en el 20 % de casos con diagnóstico de periodontitis moderada a severa (periodontitis moderada: bolsa periodontal de 6 a 7 mm y Periodontitis severa: bolsa periodontal mayor de 7 mm), presentando estos pacientes un control glicémico de condición bueno a moderado (control bueno: = 6.9 % HbAc1y control moderado: 7 a 7.9 % HbAc1). La prueba estadística realizada para valorar la relación presencia BNP y el control glicémico fue de Chi cuadrado el cual no determino significancia de la relación (P > 5 %). Conclusiones: Se identificó la presencia de BNP en pacientes diabéticos tipo 2 pero más relacionado a pacientes con cuadros de periodontitis moderada a severa y con un control glicémico de bueno a moderado, no presentando significancia estadística.

Objectives: The study aimed to identify the presence of bacilli black pigments in periodontal pockets of type 2 diabetic patients and determine a relationship with glycemic control. Material and methods: A total of 46 patients who met the criteria for inclusion in the study, of which were 20 for having completed all tests in the study, such as microbiological analysis of samples of subgingival plaque and evaluated glycosylated hemoglobin tests held periodically in the 3 months patients were assessed. Results: Of the 20 patients evaluated, 14 were women and 6 men, with an age range of 40 to 68 years, being able to identify these black bacilli pigments (BNP) in 20% of cases diagnosed with moderate to severe periodontitis (periodontitis. moderate: periodontal pocket of 6 to 7 mm and severe periodontitis: greater periodontal pocket of 7 mm), presenting these patients glycemic control in good condition to moderate (good control: = 6,9 % HbAc1 and moderate control: 7 to 7,9 % HbAc1) . The statistical test performed to assess the presence relationship BNP and glycemic control was Chi square which does not determine significance of the relationship (P> 5%). Conclusions: It was possible to identify the presence of BNP in patients with type 2 diabetes but more related to patients with moderate to severe pictures periodontitis and with good glycemic control to moderate, showing no statistical significance.

RESUMO

BACKGROUND: Diabetes is a serious health problem for pediatrics. In pediatric patients control depends on correct insulin administration. The most usual is subcutaneous administration according to the glycemic control. The aim was to analyze the indications for continuous subcutaneous insulin infusion (CSII) in type 1 diabetes mellitus (T1DM) children and adolescents. METHODS: It was carried out a descriptive study in patients from 1 to 16 years with T1DM who underwent CSII therapy. The main cause to use this therapy was analyzed, and also if that cause was different regarding age, sex and disease progression. RESULTS: 61 patients underwent CSII therapy. The median age at the beginning of treatment was 9 years old; 43 patients (71.6 %) had more than one year of diagnosis. The main reasons to use CSII were: 42.6 % had to improve their quality of life, 34.4 % had to reduce the high glycemic variability, 13.1 % had to control severe recurrent hypoglycemia, and 9.8 % had to control their HbA1c. For children under 6 years of age (n = 14) the more frequent indication were recurrent hypoglycemia and to improve their quality of life; children from 6 to 12 years of age (n = 27) had to improve their quality of life, and in children over 12 years CSII was indicated for high glycemic variability and severe recurrent hypoglycemia. There was no different indication related between sexes. CONCLUSION: Improve their quality of life and reach a better glycemic control were the main reasons to start CSII in our patients.

Introducción: la diabetes es un problema serio de salud para la pediatría. En pacientes de ese grupo etario, el control depende de la adecuada administración de la insulina.Se buscó analizar las indicaciones para el uso de terapia de infusión continua subcutánea de insulina (ICSI) en niños y adolescentes con diabetes mellitus 1 (DM1). Métodos: estudio descriptivo en pacientes de 1 a 16 años con DM1, en quienes se propuso el inicio de la terapia con ICSI. Se analizó el motivo principal para justificar su inicio y si este fue diferente según edad, sexo y tiempo de evolución. Resultados: en 61 pacientes se aceptó el inicio de ICSI. La mediana de edad fue de 9 años al momento de la colocación y 43 pacientes (71.6 %) tuvieron más de un año de diagnóstico. Los motivos principales para su inicio fueron: 42.6 % (26 de 61) ante un deseo de mejorar su calidad de vida; 34.4 % (21 de 61) para reducir una variabilidad glucémica importante; 13.1 % (8 de 61) para controlar hipoglucemias recurrentes, y 9.8 % (6 de 61) para lograr metas de control en su valor de HbA1c. En los menores de 6 años (n = 14) se indicó más por hipoglucemias recurrentes y para mejorar su calidad de vida; para los de 6 a 12 años (n = 27) para mejorar su calidad de vida; y en los mayores de 12 años (n = 20) por variabilidad glucémica importante e hipoglucemias recurrentes. No hubo diferencias por sexos. Conclusión: los principales motivos que influyeron en la indicación de la ICSI en nuestros pacientes pediátricos fueron mejorar su calidad de vida y lograr un mejor control glucémico.

RESUMO

Objetivo Avaliar se há correlação das dosagens de frutosamina e de hemoglobina glicosilada (HbA1c) com as frequências de desvios de glicemia capilar em gestantes com diabetes mellitus. Métodos estudo observacional, retrospectivo, de corte transversal, incluindo todas as gestantes comdiabetes que iniciaram o pré-natal emhospital terciário de ensino durante o ano de 2014 e que apresentavam pelo menos 20 dias de auto monitoramento glicêmico previamente às dosagens séricas de frutosamina e de HbA1c. Os desvios de glicemia capilar foram considerados "hipoglicemias" quando menores que 70mg/dL ou "hiperglicemias" quando acima do alvo glicêmico terapêutico para o horário. Foram testadas as correlações lineares par a par das dosagens de frutosamina e de HbA1c com as frequências de hipoglicemias e de hiperglicemias capilares pelo teste Tau-b de Kendall. Na sequência, foi avaliada a regressão linear entre as dosagens de HbA1c e de frutosamina e as frequências de hipoglicemias e de hiperglicemias. Resultados Foram incluídas 158 gestantes que contribuíram com 266 amostras para dosagem sérica de frutosamina e HbA1c. As dosagens de frutosamina e de HbA1c apresentaram, respectivamente, coeficientes τ de Kendall de 0,29 (p < 0,001) e 0,5 (p < 0,001) com a frequência de hiperglicemias, e de 0,09 (p = 0,04) e 0,25 (p < 0,001) com a frequência de hipoglicemias capilares. No modelo de regressão linear, as dosagens de frutosamina e de HbA1c apresentaram, respectivamente, coeficientes de determinação R2 = 0,26 (p < 0,001) e R2 = 0,51 (p < 0,001) para a predição de hiperglicemias, e R2 = 0,03 (p = 0,003) e R2 = 0,059 (p < 0,001) para a predição de hipoglicemias. Conclusão As dosagens de frutosamina e de HbA1c apresentam correlação fraca a moderada com as frequências de hiperglicemias e hipoglicemias capilares no auto monitoramento glicêmico e não são capazes de traduzir com precisão os desvios da meta glicêmica no tratamento de gestantes com diabetes.

Objective To evaluate the correlation of the levels of fructosamine and of glycated hemoglobin (HbA1c) with the frequency of blood glucose self-monitoring values out of the treatment target range in pregnant women with diabetes mellitus. Methods We performed an observational, retrospective, cross-sectional study, including all pregnant women with diabetes who attended prenatal care visits at a tertiary teaching hospital during the year of 2014 and who presented at least 20 days of blood glucose self-monitoring prior to assessment of serum levels of fructosamine and HbA1c. Capillary blood glucose values out of the treatment target range were considered "hypoglycemia" when lower than 70 mg/dL and "hyperglycemia" when above the glycemic therapeutic target. We evaluated the correlation of the levels of fructosamine and of HbA1c with the frequencies of hyperglycemia and hypoglycemia recorded in the glucometer device by performing Tau-b of Kendall correlation tests. Next, linear regression tests were performed between the levels of HbA1c and of fructosamine and the frequencies of hypoglycemia and hyperglycemia. Results We included 158 pregnant women, from whom 266 blood samples were obtained for assessing fructosamine and HbA1c levels. Measurements of fructosamine and of HbA1c presented, respectively, Kendall's τ coefficient of 0.29 (p < 0.001) and 0.50 (p < 0.001) regarding the frequency of hyperglycemia, and of 0.09 (p = 0.046) and 0.25 (p < 0.001) regarding the frequency of hypoglycemia. In the linear regression model, levels of fructosamine and of HbA1c respectively presented determination coefficients R2 = 0.265 (p < 0.001) and R2 = 0.513 (p < 0.001) for the prediction of hyperglycemia, and R2 = 0.033 (p = 0.003) and R2 = 0.059 (p < 0.001) for the prediction of hypoglycemia. Conclusion Levels of fructosamine and of HbA1c presented a weak to moderate correlation with the frequencies of hyperglycemia and hypoglycemia at blood glucose self-monitoring and were not able to accurately translate the deviations from the glycemic goals in pregnant women with diabetes.

RESUMO

BACKGROUND: In 2009 it was introduced a new diagnostic criteria based on hemoglobin A1c (HbA1c) greater than or equal to 6.5 % in the adult population; some studies suggest that the cutoff may be smaller in pediatric population. The objective was to determine the utility of HbA1c greater than or equal to 6.5 % as a diagnostic test for DM in Mexican adolescents with overweight or obesity. METHODS: Full somatometry was performed. Also, Tanner stage, blood pressure, blood glucose, glucose tolerance curve (GTC) and HbA1c were analyzed. Specificity, sensitivity, positive and negative predictive values and ROC curve were calculated for the diagnosis of DM with HbA1c. RESULTS: 109 adolescents between 10 and 16 years referred for obesity or overweight plus comorbidities were studied; 58 % were females, the age was of 13 ± 1.74 years, the BMI percentile 95.3, and the HbA1c 5.73 ± 0.9 %. It was made a diagnosis of DM in 9 cases (8.3 %), prediabetes in 8 (7.3 %) and normal glucose tolerance in 92 (84.4 %). The HbA1c mean was 5.6 ± 0.04, 5.7 ± 0.4, and 5.6 ± 0.73 %, respectively. HbA1c greater than or equal to 6.5 % had a sensitivity of 12.5 %, a specificity of 89.8 %, a PPV of 10.65 and a NPV of 14.28. The best cutoff point for diagnosing DM through ROC curve was 5.45 %, with a sensitivity of 62.5 %, a specificity of 57.1 %, PPV 2.53 and NPV 33.3. CONCLUSIONS: The level of HbA1c greater than or equal to 6.5 % had low sensitivity and specificity for the diagnosis of DM. A lower cutoff point is insufficient to use HbA1c as a diagnostic criterion. These results are consistent with the ones of other journals.

Introducción: en 2009 se introdujo un criterio diagnóstico para la diabetes mellitus 2 (DM2) en población adulta, basado en los niveles de hemoglobina glucosilada (HbA1c) mayor o igual a 6.5 %; el punto de corte en población pediátrica podría ser menor. Se buscó determinar la utilidad de este criterio en adolescentes mexicanos con sobrepeso u obesidad. Métodos: se hizo somatometría completa, revisión del estadio de Tanner y presión arterial, glucemia, curva de tolerancia a la glucosa (CTOG) y HbA1c. Se calculó especificidad, sensibilidad, valores predictivos positivos y negativos y curva ROC para el diagnóstico de DM con HbA1c. Resultados: se estudiaron 109 pacientes entre 10 y 16 años referidos por obesidad o sobrepeso más comorbilidades, 58 % mujeres, edad 13 ± 1.74 años, IMC percentil 95.3 y HbA1c 5.73 ± 0.9 %. Se estableció el diagnóstico de DM en 9 casos (8.3 %), prediabetes en 8 (7.3 %) y tolerancia normal a la glucosa en 92 (84.4 %), el promedio de HbA1c fue de 5.6 ± 0.04, 5.7 ± 0.4 y 5.6 ± 0.73 %, respectivamente. La HbA1c mayor o igual a 6.5 % tuvo una sensibilidad de 12.5 %, especificidad de 89.8 %, VPP 10.65 y VPN 14.28. El mejor punto de corte para diagnosticar DM por curva ROC de HbA1c fue de 5.45 %, con sensibilidad de 62.5 % y especificidad de 57.1 %, VPP 2.53 y VPN 33.3. Conclusiones: el nivel de HbA1c mayor o igual a 6.5% tuvo baja sensibilidad y especificidad para diagnosticar DM. Un punto de corte menor es insuficiente para utilizar la HbA1c como criterio diagnóstico.

RESUMO

El objetivo de este estudio fue determinar la relación entre los parámetros de control metabólico y la calidad de los hidratos de carbono (H de C) de la dieta, en sujetos diabéticos tipo 2 (DM 2), controlados con dieta y/o metformina. A 108 hombres y mujeres con edades comprendidas entre 18 y 60 años, hemoglobinas glicosiladas (HbA1c) entre 6% y 10%, sin sulfonilureas ni insulinoterapia; se les aplicó dos encuestas de recordatorio de 24 horas. Se determinó la ingesta de H de C, el índice glicémico (IG) y la carga glicémica (CG) de la dieta. Desde las fichas clínicas se obtuvieron valores recientes de HbA1c. Los datos fueron tabulados en el programa SPSS versión 17. Se utilizó el test de correlación de Pearson para analizar el grado de asociación entre las variables, considerándose significativo un p < 0,05. El promedio de HbA1c fue de 7,3 ± 1,3 %, el consumo de H de C fue de 219,8 ± 27,0 g/día; el IG fue de 74,9 ± 11,3 % y la CG fue de 164,0 ± 22,04 g. Se encontró correlación positiva y significativa entre el consumo de H de C (r=0,290; p<0,05), IG (r=0,70; p<0,001) y CG (r=0,225; p<0,05) de la dieta con los niveles de HbA1c de los sujetos estudiados. En conclusión la calidad de los H de C, especialmente el IG, de la dieta de los sujetos estudiados se asocia fuertemente al control metabólico de la DM 2.

The Objective of this study was to determine the relationship between the parameters of metabolic control and quality of carbohydrates (CHO) of the diet in individuals with type 2 diabetes, controlled with diet and / or Metformin. In 108 men and women aged between 18 and 60 years, glycosylated hemoglobin A (HbA1c) between 6 % and 10 %, without sulfonylureas or insulintheraphy; were examined through two separate surveys of 24-hour recall. The CHO intake, GI, GL of diet was analyzed. Values of HbA1c were collected from medical records. Data was tabulated in SPSS version 17 software. The Pearson correlation test was used to analyze the degree of association between variables, considering significant at p < 0.05. The mean HbA1c was 7.3 ± 1.3%, CHO consumption was 219.8 ± 27.0 g / day; GI was 74.9 ± 11.3% and GL was 164.0 ± 22.04 g. A significant positive correlation was found out between the CHO intake (r = 0.290, P < 0.05), GI (r = 0.70, p < 0.001), GL (r = 0.225, p < 0.05) of diet and HbA1c levels in the individuals. In conclusion the study showed that the quality of CHO, mainly GI, are strongly associated with metabolic control of DM 2.

RESUMO

O diabete mellitus (DM) é uma doença multifatorial que acomete diversos sistemas corporais com complicações teciduais e vasculares. Diversas hipóteses bioquímicas estão implicadas na indução das complicações tardias da diabete, como: radicais livres, rota dos polióis e glicação não enzimática de proteínas. O objetivo do presente estudo foi correlacionar o perfil lipídico e lipoperoxidação em indivíduos diabéticos. Realizou-se uma análise do perfil lipídico de 30 pacientes diabéticos do tipo 2, com uma média de 4 anos da evolução da doença. Analisou-se a concentração sanguínea de glicose, colesterol total, HDLc, LDLc, VLDLc, triglicerídeos, hemoglobina glicada e peroxidação lipídica (TBARS). Encontrou-se uma forte correlação entre a concentração de triglicerídeos, colesterol total e VLDLc com o dano oxidativo e uma fraca correlação com colesterol LDLc e HDLc. A análise dos resultados mostra uma forte correlação da lipoperoxidação lipídica com o perfil lipídico dos pacientes que pode reafirmar a necessidade de monitoramento dos lipídios plasmáticos como forma de prevenir complicações tardias inerentes ao diabete.

Diabete mellitus (DM) is a multifactorial disease that affects several body systems, with vasculacomplications and tissue damage. Several biochemical mechanisms are hypothetically implicated in the induction of the late complications of diabete, such as the action of free radicals, glucose metabolism by the polyol pathway and non-enzymatic glycation of proteins. The aim of this study was to correlate the lipid profile and lipid peroxidation in diabetic subjects. An analysis of the lipid profile of 30 diabetic patients, with an average of 4 years since diagnosis. We analyzed the concentration of glucose, total cholesterol, HDLc, LDLc, VLDLc, triglycerides, glycated hemoglobin and lipid peroxidation (TBARS). Oxidative damage (TBARS) showed a strong correlation with the concentration of triglycerides, total cholesterol and VLDLc, and a weak correlation with LDLc cholesterol and HDLc. The strong correlation found between lipid peroxidation and the lipid profile of these patients reinforces the need to monitor plasma lipids in order to prevent late complications associated with diabete.

RESUMO

Objetivo: Avaliar a condição periodontal dos pacientes diabéticos tipo 2, relacionando com o controle de marcadores metabólicos.Método: Para este estudo foram selecionados 92 pacientes diabéticos que recebiam tratamento em dois centros de referência em Recife, Brasil. Foram realizados exames clínicos periodontais em seis sítios de cada dente, avaliando a profundidade de sondagem, sangramento à sondagem, perda de inserção, índice de placa dentária e número de dentes presentes. A doença periodontal foi definida pela presença de mais de 4 sítios com perda de inserção ≥ 5 mm, sendo um ou mais destes sítios com profundidade de sondagem de 4 mm ou mais. Foram realizados exames hematológicos para avaliar os marcadores metabólicos (hemoglobina glicosilada, glicemia de jejum, triglicérides, colesterol total, colesterol HDL e LDL). Foi realizada análise estatística bi-variada para verificar a associação entre as variáveis em estudo.Resultados: A avaliação da condição periodontal dos pacientes avaliados mostrou que 59,8% dos pacientes diabéticos eram portadores de doença periodontal, caracterizada por periodontite. A média de idade observada foi de 54,8 anos com DP = 9,3, o sangramento gengival à sondagem e o índice de placa foram de 33,8% e 61,07%, respectivamente. A maioria dos pacientes com níveis elevados de glicemia (≥ 126 mg / dL) apresentaram doença periodontal (62,3%),o perfil lipídico dos pacientes com doença periodontal se mostrou controlado.Conclusão: Não foi observada associação entre a condição periodontal e os marcadores do controle metabólico dos pacientes diabéticos

Objective: Evaluate the periodontal condition in diabetic patients type 2, relating to markers of metabolic control.Methods: 92 diabetic patients who received treatment in two centers in Recife, Brazil, had been invited to participate in this study. It was carried through periodontal clinical examinations in six sites of each tooth, evaluating the depth probing, bleeding probing, attachment loss, dental plaque and the number of teeth present. Periodontal disease was defined as the presence of 4 + sites with attachment loss of ≥ 5 mm with one or more than these sites with depth probing of 4 + mm. Hematologic examinations were carried out to evaluate the metabolic markers (Glycosylated Hemoglobin, fasting blood glucose, triglycerides, total cholesterol, cholesterol HDL and LDL). Bi-variate analysis were used to verified the association between variables.Results: Evaluation of periodontal condition in the sample have shown 59.8% of diabetic patients had periodontal diseases, characterized as periodontitis. The average of age observed was 54.8 years with DP= 9.3, average of bleed on probing and plaque index were 33.8% and 61.07%, respectively. The majority of patients with raised glicemic levels (≥126 mg/dL) had presented DP (62,3%), in relation to the lipidic profile the patients with periodontal disease had been presented controlled. Conclusion: In the studied population there were no signs of any association between the periodontal condition and the markers of metabolic control

RESUMO

Objetivos: dois estudos prospectivos comparativos de intervenção foram realizados para avaliar o efeito do tratamento periodontal não-cirúrgico sobre parâmetros clínicos periodontais e imunológicos do fluido sulcular gengival e do plasma sanguíneo de pacientes com periodontite crônica portadores ou não de Diabetes mellitus Tipo 2. Material e Método: Vinte e três indivíduos com Diabetes mellitus Tipo 2 com controle metabólico inadequado e periodontite crônica (grupo diabetes) e 26 indivíduos sistemicamente saudáveis com periodontite crônica (grupo controle) foram avaliados quanto a parâmetros periodontais, marcadores inflamatórios do fluido sulcular gengival (interleucinas, metaloproteinases de matriz e atividade de elastase), marcadores inflamatórios no plasma sanguíneo (interleucinas, fator de necrose tumoral alfa, proteína C-reativa e fibrinogênio) e perfil lipídico, antes e após 3 meses do tratamento periodontal. Adicionalmente foi avaliada a influência do tratamento periodontal no controle glicêmico do grupo com diabetes. Resultados: houve redução significativa de todos os marcadores inflamatórios avaliados no fluido gengival, exceto a interleucina 18, após tratamento periodontal, associado a uma melhora da condição clínica periodontal em ambos os grupos. Sistemicamente, o grupo diabetes apresentou maiores níveis de proteina C reativa e triglicérides em ambos os períodos ao se comparar com o grupo controle. O tratamento periodontal foi efetivo em reduzir os níveis de TNF-_ e fibrinogênio no grupo diabetes. Houve melhora no controle glicêmico embora não significativa. Conclusão: os resultados do presente estudo sugerem que os pacientes portadores de Diabetes mellitus Tipo 2 com controle metabólico inadequado apresentam boa resposta ao tratamento periodontal nãocirúrgico, com redução de marcadores inflamatórios no fluido gengival.

Objetive: Two prospective comparative interventional studies were performed in order to evaluate the effect of non-surgical periodontal therapy on periodontal clinical and immunological parameters in gingival crevicular fluid (CGF) and plasma of patients with chronic periodontitis with or without type 2 Diabetes mellitus (T2DM). Material and Method: Twenty three individuals with inadequately controlled T2DM and chronic periodontitis (diabetes group) and 26 systemically healthy individuals with periodontitis (control group) were assessed for clinical parameters, inflammatory biomarkers in GCF (interleukins, matrix metalloproteinases and elastase activity), circulating markers of inflammation (interleukins, tumor necrosis factor alpha, C-reactive protein and fibrinogen and lipid profile before and 3 months after periodontal therapy. Additionally, the influence of periodontal treatment on glycemic control was evaluated in the diabetes group. Results: There was a significant reduction of all inflammatory biomarkers in GCF after therapy, except for interleukin 18 levels, and it was associated with improvement on periodontal status in both groups. Systemically, the diabetes group showed high levels of C-reactive protein and triglycerides compared with the control group in both periods. The periodontal therapy was effective in reducing TNF-_ circulating and fibrinogen in the diabetes group. The treatment did not change the glycemic control significantly. Conclusion: The results of the present study suggest that patients with inadequately controlled T2DM present a good response to nonsurgical periodontal treatment, with reduction of inflammatory biomarkers in GCF. However, 3 months after therapy, its influence on systemic inflammatory condition is limited.
