ABSTRACT

Abstract: There is a conflict in the literature regarding the association between serum uric acid (SUA) levels and glycemic status. Therefore, we evaluated the association between SUA level and glycemic status - impaired fasting glucose (IFG), impaired glucose tolerance (IGT), and diabetes mellitus - and insulin resistance, in a large Brazilian study. This is a cross-sectional, observational study with 13,207 participants aged 35-74 years, at baseline (2008-2010) of the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil). A multinomial regression analysis was performed to test the association between SUA and glycemic status (IFG, IGT, and newly diagnosed type 2 diabetes at the cohort baseline) after adjustments by age, sex, skin color, body mass index, physical activity, smoking, alcohol consumption, comorbidities, and medicines use. Logistic regression model was used to evaluate the association between SUA and insulin resistance by HOMA-IR. Stratified analyses by sex were performed. The mean age (standard deviation) was 51.4 (8.9) years, 55.2% of participants were women. There were 1,439 newly diagnosed diabetes. After all adjustments, higher SUA was associated with IFG, IGT, and diabetes, with odds ratio (OR) = 1.15 (95%CI: 1.06; 1.25), 1.23 (95%CI: 1.14; 1.33), and 1.37 (95%CI: 1.24; 1.51), respectively. There was association between SUA levels and insulin resistance with OR = 1.24 (95%CI: 1.13; 1.36). In analysis stratified by sex, higher SUA persisted independently associated with impaired glycemic status. Our results suggest that a higher SUA levels were significantly associated with glycemic status in a large Latin American population, mainly among women.


Resumo: Há uma controvérsia na literatura a respeito da associação entre níveis de ácido úrico sérico (AUS) e glicemia. Portanto, avaliamos a associação entre AUS e glicemia (glicemia em jejum alterada, intolerância glicêmica e diabetes mellitus), além da resistência insulínica, em uma amostra grande no Brasil. O estudo transversal observacional incluiu 13.207 participantes com idade entre 35 e 74 anos na linha de base (2008-2010) do Estudo Longitudinal de Saúde do Adulto (ELSA-Brasil). Foi realizada análise de regressão multivariada para testar a associação entre AUS e glicemia (glicemia em jejum alterada, intolerância glicêmica e diagnóstico novo de diabetes tipo 2 na linha de base da coorte) depois de ajustar para idade, sexo, cor, índice de massa corporal, atividade física, tabagismo, consumo de álcool, comorbidades e uso de medicação. O modelo de regressão logística foi usado para avaliar a associação entre AUS e resistência insulínica por HOMA-IR. Foram realizadas análises estratificadas por sexo. A média de idade (DP) foi 51,4 (8,9) anos, e 55,2% dos participantes eram mulheres. Houve 1.439 novos diagnósticos de diabetes. Depois de todos os ajustes, o AUS esteve associado à glicemia em jejum alterada, intolerância glicêmica e diabetes, com odds ratio (OR) = 1,15 (IC95%: 1,06; 1,25), 1,23 (IC95%: 1,14; 1,33) e 1,37 (IC95%: 1,24; 1,51), respectivamente. Houve uma associação entre níveis de AUS e resistência insulínica, com OR = 1,24 (IC95%: 1,13; 1,36). Na análise estratificada por sexo, persistiu a associação independente entre AUS elevado e glicemia. Os resultados sugerem que níveis elevados de AUS estão associados de maneira significativa com a glicemia em uma população latino-americana grande, sobretudo entre mulheres.


Resumen: Hay un conflicto en la literatura respecto a la asociación entre los niveles de ácido úrico sérico (AUS) y el estado glucémico. Por eso, evaluamos la asociación entre el nivel AUS y el estatus glucémico: glucosa alterada en ayunas (GAA), tolerancia a la glucosa alterada (TGA) y diabetes mellitus (diabetes), comparados con la resistencia a la insulina en un amplio estudio en Brasil. Se realizó un estudio transversal, observacional con 13.207 participantes, con edades comprendidas entre los 35-74 años, en la base de referencia del Estudio Longitudinal de Salud entre Adultos brasileños (2008-2010) (ELSA-Brasil). Se realizó un análisis de regresión multinomial para probar la asociación entre AUS y el estado glucémico (GAA, TGA y de nuevo la diabetes tipo 2, diagnosticada en la cohorte como base de referencia) tras los ajustes por edad, sexo, color de piel, índice de masa corporal, actividad física, fumar, consumo de alcohol, comorbilidades, uso de medicinas. Se usó el modelo de regresión logística para evaluar la asociación entre AUS y la resistencia a la insulina por el HOMA-IR. Se realizó también un análisis estratificado por sexo. La media de edad (desviación estándar) fue 51,4 (8,9) años, un 55,2% de los participantes eran mujeres. Hubo 1.439 nuevos casos de diabetes diagnosticados. Tras todos los ajustes, una AUS más alta estuvo asociada con GAA, TGA y diabetes, con odds ratio (OR) = 1,15 (IC95%: 1,06; 1,25), 1,23 (IC95%: 1,14; 1,33), y 1,37 (IC95%: 1,24; 1,51), respectivamente. Hubo asociación entre los niveles AUS y la resistencia a la insulina con OR = 1,24 (IC95%: 1,13; 1,36). En el análisis estratificado por sexo, una AUS más alta persistía independientemente asociada con un estado glucémico alterado. Nuestros resultados sugieren que unos niveles más altos de AUS estuvieron significativamente asociados con el estado glucémico en una amplia población latinoamericana, principalmente entre mujeres.

ABSTRACT

BACKGROUND@#The prevalence of skin diseases and diabetes mellitus (DM) are prominent around the world. The current scope of knowledge regarding the prevalence of skin diseases and comorbidities with type 2 DM (T2DM) is limited, leading to limited recognition of the correlations between skin diseases and T2DM.@*METHODS@#We collected 383 subjects from the Da Qing Diabetes Study during the period from July 9th to September 1st, 2016. The subjects were categorized into three groups: Normal glucose tolerance (NGT), impaired glucose tolerance (IGT), and T2DM. The prevalence and clinical characteristics of skin diseases were recorded and investigated.@*RESULTS@#In this cross-sectional study, 383 individuals with ages ranging from 53 to 89-year-old were recruited. The overall prevalence of skin diseases was 93.5%, and 75.7% of individuals had two or more kinds of skin diseases. Additionally, there were 47 kinds of comorbid skin diseases in patients with T2DM, of which eight kinds of skin diseases had a prevalence >10%. The prevalence of skin diseases in NGT, IGT, and T2DM groups were 93.3%, 91.5%, and 96.6%, respectively; stratified analysis by categories showed a statistically significant difference in "disturbances of pigmentation" and "neurological and psychogenic dermatoses". The duration of T2DM also significantly associated with the prevalence of "disturbances of pigmentation" and "neurological and psychogenic dermatoses". Subsequently, the prevalence of "disturbances of pigmentation" was higher in males than females in NGT (P < 0.01) and T2DM (P < 0.01) groups. In addition, the difference in the prevalence of "disturbances of pigmentation" was also significant in NGT and T2DM groups (P < 0.01).@*CONCLUSIONS@#There was a high prevalence of skin diseases in the Da Qing Diabetes Study. To address the skin diseases in the Da Qing Diabetes Study, increased awareness and intervention measures should be implemented.

ABSTRACT

Vitamin D deficiency and diabetes mellitus are two common conditions and they are widely prevalent across all ages, races, geographical regions, and socioeconomic conditions. Epidemiologic studies have shown association of vitamin D deficiency and increased risk of chronic diseases, such as cancer, cardiovascular disease, type 2 diabetes, and autoimmune diseases, such as multiple sclerosis and type 1 diabetes mellitus. The identification of 1,25(OH)2D receptors and 1-α-hydroxilase expression in pancreatic beta cells, in cells of the immune system, and in various others tissues, besides the bone system support the role of vitamin D in the pathogenesis of type 2 diabetes. Observational studies have revealed an association between 25(OH) D deficiency and the prevalence of type 1 diabetes in children and adolescents. This review will focus on the concept of vitamin D deficiency, its prevalence, and its role in the pathogenesis and risk of diabetes mellitus and cardiovascular diseases.


A deficiência de vitamina D e o diabetes melito são enfermidades comuns na população e são altamente prevalentes em todas as raças, idades, regiões geográficas e situação socioeconômica. Estudos epidemiológicos mostram uma associação entre hipovitaminose D com o aumento do risco de doenças crônicas, tais como câncer, doença cardiovascular, diabetes melito do tipo 2 e doenças autoimunes como a esclerose múltipla e o diabetes mellitus do tipo 1. A identificação de receptores da 1,25(OH)2 D e da expressão da 1 α-hidroxilase nas células betapancreáticas, em células do sistema imunológico e em uma variedade de células do organismo além do tecido ósseo, suporta o papel da vitamina D na patogênese do diabetes tipo 2 e do tipo 1. Esta revisão apresenta e discute o conceito de deficiência de vitamina D, sua prevalência e seu papel na patogênese e no risco de desenvolvimento do diabetes melito e doenças cardiovasculares.

ABSTRACT

Objective: Estimating the prevalence of diabetes mellitus (DM) and impaired glucose tolerance (IGT) in the urban population aged between 30 and 69 years in the municipality of Campo Grande, state of Mato Grosso do Sul, Brazil. Methods: Population-based cross-sectional study conducted between October/2009 and February/2011. The investigation included the determination of fasting glucose and participants with blood glucose ≥ 200 mg/dL were considered diabetic. Nondiabetic patients, which showed blood glucose ≥ 100 mg/dL and < 200 mg/dL, underwent an oral glucose tolerance test (OGTT) to investigate whether they had DM or IGT. Results: 1.429 individuals participated in this investigation. The general prevalence, adjusted for sex and age, were: 12.3% for DM (95%CI: 10.5 to 13.9%) and 7.1% for IGT (95%CI: 5.7 to 8.4%). There was a higher prevalence of DM with increasing age in people with low educational level, family history of diabetes, overweight, obesity and central obesity. Among diabetic patients (n = 195), 25% were unaware they had the disease and were diagnosed through investigation. Among patients who already knew they had DM (n = 146), 37% were unaware of the potential chronic complications. Conclusion: This study confirms the increased prevalence of DM in Brazil and emphasizes the need for early diagnosis, as well as the importance of strict adherence to medical treatment in order to prevent its much feared complications. .


Objetivo: estimar a prevalência de diabete melito (DM) e a tolerância diminuída à glicose (TDG) na população urbana de idade entre 30 e 69 anos do município de Campo Grande/MS. Métodos: estudo transversal de base populacional realizado entre 10/2009 e 2/2011. Na investigação, foi realizada a dosagem da glicemia capilar em jejum e os participantes com glicemia ≥ 200 mg/dL foram considerados diabéticos. Os não diabéticos, que apresentaram glicemia ≥ 100 mg/dL e < 200 mg/dL, foram submetidos a um teste oral de tolerância à glicose (TOTG) para investigar se tinham DM ou TDG. Resultados: nesta investigação, participaram 1.429 indivíduos. As prevalências gerais, ajustadas por sexo e faixa etária, foram: para DM de 12,3% (IC95%: 10,5 a 13,9%) e para TDG de 7,1% (IC95%: 5,7 a 8,4%). Houve maior prevalência de DM com o aumento da idade, em pessoas com baixa escolaridade, histórico de diabete na família, sobrepeso, obesidade e obesidade central. Do total de diabéticos (n= 195), 25% não sabiam que tinham a doença e obtiveram o diagnóstico por meio da investigação. Dos pacientes que já sabiam ter DM (n= 146), 37% desconheciam as potenciais complicações crônicas. Conclusão: este estudo corrobora o aumento da prevalência de DM no Brasil e enfatiza a necessidade de sua constatação precoce, bem como da importância da adesão rigorosa ao tratamento médico com o intuito de prevenir suas temíveis complicações. .

ABSTRACT

OBJETIVO: Avaliar a prevalência de diabetes melito (DM) e de tolerância à glicose diminuída em indígenas da Aldeia Jaguapiru, em Dourados, Estado de Mato Grosso do Sul. MÉTODOS: Foram avaliados indígenas de 18 a 69 anos de idade entre agosto de 2007 e julho de 2008. A amostra aleatória simples foi obtida pelo sorteio de 349 de 1 255 casas da Aldeia. Excluíram-se as mulheres grávidas, os indivíduos não indígenas e seus descendentes moradores na Aldeia, além dos usuários de glicocorticoide. A amostra incluiu 606 pessoas, 268 ho-mens e 338 mulheres. Realizaram-se dosagens da glicemia capilar com glicosímetro e teste de tolerância oral à glicose, quando necessário. RESULTADOS: A prevalência de DM foi de 4,5 por cento, e a de tolerância diminuída à glicose, de 2,2 por cento, com maior frequência entre as mulheres. Dos diabéticos, 44,4 por cento não tinham diagnóstico. A obesidade esteve presente em 14,2 por cento dos homens e em 30,8 por cento das mulheres. A prevalência de hipertensão arterial foi de 29,7 por cento entre todos os sujeitos participantes e de 67,5 por cento entre os diabéticos e os indivíduos com tolerância à glicose diminuída. Não foi encontrada associação estatística entre fumar e presença de DM ou de tolerância à glicose diminuída. CONCLUSÕES: As prevalências de DM e de tolerância à glicose diminuída foram inferiores nesta amostra em relação à população brasileira; entretanto, a prevalência de obesidade foi maior e a de hipertensão arterial foi semelhante. São recomendáveis orientações nutricionais e incentivo à prática de atividades físicas entre os indígenas da Aldeia Jaguapiru como forma de prevenção do DM.


OBJECTIVE: To determine the prevalence of diabetes mellitus (DM) and impaired glucose tolerance in indigenous people from Aldeia Jaguapiru, in Dourados, state of Mato Grosso do Sul. METHODS: Between August 2007 and July 2008, individuals aged 18-69 years were evaluated. To obtain the simple random sample for the study, 349 houses were picked from among the total 1 255 houses in the village. Pregnant women, nonindigenous individuals, and their descendents, and those using glucocorticoids were excluded from the sample. Six hundred and six people were studied (268 men and 338 women). Capillary glucose was measured with a glucose meter, and the oral glucose tolerance test was performed as necessary. RESULTS: A 4.5 percent prevalence was observed for DM and 2.2 percent for impaired glucose tolerance, with higher frequency among women. Among diabetics, 44.4 percent had not been previously diagnosed. Obesity was present in 14.2 percent of men and 30.8 percent of women. The prevalence of hypertension was 29.7 percent for the overall group and 67.5 percent in diabetics and individuals with impaired glucose tolerance. There was no statistical relationship between smoking and the presence of DM and impaired glucose tolerance. CONCLUSIONS: The prevalence of DM and impaired glucose tolerance was lower in this sample compared to the Brazilian population. However, the prevalence of obesity was higher, and that of hypertension was similar. Nutritional guidance and encouragement of physical activity are recommended in Jaguapiru as preventive measures for DM.

ABSTRACT

ANTECEDENTES: La obesidad en mujeres en edad reproductiva es cada vez más frecuente y complica el embarazo aumentando el riesgo de enfermedades como la diabetes mellitus gestacional (DMG). OBJETIVO: Determinar el riesgo de presentar DMG e intolerancia a la glucosa (ITG) de acuerdo con el índice de masa corporal pregestacional (IMCPG). MÉTODO: Muestra de 489 pacientes, se clasificaron por IMCPG y se les realizó una curva de tolerancia oral a la glucosa (CTOG) de 100 g de 120 minutos. Se definió DMG con dos valores alterados en la CTOG e ITG con un solo valor alterado. Se aplicó prueba de chi cuadrada para determinar diferencia entre grupos y se obtuvo un Odds Ratio (OR), con intervalo de confianza del 95%. RESULTADOS: 9 pacientes con bajo peso, 194 con peso normal, 158 con sobrepeso y 128 con obesidad, edad gestacional promedio 31,3 ± 5,6 semanas. El 13% de las pacientes presentaron DMG, el 10,6% ITG. Las mujeres con sobrepeso presentaron un OR de 3,81 para desarrollar ITG (IC95% 1,62-8,95) y un OR de 3,7 para DMG (IC95% 1,65-8,38), mientas que las pacientes con obesidad pregestacional presentaron un OR de 6,6 para desarrollar ITG (IC95% 2,83-15,66) y un OR de 8,8 para DMG (IC95% 4,05-19,51), comparadas con mujeres con peso pregestacional normal. CONCLUSIÓN: La población mexicana tiene mayor riesgo de DMG que otras poblaciones y mayor prevalencia de sobrepeso y obesidad, por lo que se debe realizar un diagnóstico y tratamiento oportuno de DMG, previniendo complicaciones y diabetes mellitus tipo 2.


BACKGROUND: Obesity in women in reproductive age is becoming more frequent and it self complicates preg-nancy increasing the risk of diseases such as gestational diabetes mellitus (GDM). AIMS: To determine the risk of gestational diabetes mellitus (GDM) and impaired glucose tolerance (IGT) according to the pregestational body mass index (PGBMI). METHODS: Sample of 489 patients, they were classified by PGBMI and underwent an oral glucose tolerance test (OGTT) with 100 g of glucose during 120 minutes. GDM was defined with two altered valúes in the OGTT and IGT with a single altered value. A chi-square test was applied to determine difference between groups, and we obtained an Odds Ratio (OR), with a confidence level of 95%. RESULTS: 9 patients were low weight, 194 normal weight, 158 overweight and 128 obese, average gestational age 31.3 ± 5.6 weeks. 13% of the patients had GDM, 10.6% had IGT. Overweight women had an OR of 3.81 of developing IGT (95% Cl 1.62-8.95) and an OR of 3.7 of developing GDM (95% Cl 1.65-8.38), while women with prepregnancy obesity showed an OR of 6.6 of developing ITG (95% Cl 2.83-15.66) and an OR of 8.8 of developing GDM (95% Cl 4.05-19.51), all compared to women with prepregnancy normal weight. CONCLUSIONS: Mexican population has a higher risk of GDM than other populations and also a higher prevalence of overweight and obesity, so that every pregnant woman should be screening for GDM, has a diagnosis and receive treatment, preventing complications and Type 2 Diabetes.

ABSTRACT

CONTEXT AND OBJECTIVE: Early diagnosis of prediabetes should be done to avoid complications relating to diabetes mellitus (DM). The aim here was to assess the prevalence of prediabetes among individuals at high risk of developing DM, and to seek variables relating to glucose intolerance (GI) among individuals with normal fasting plasma glucose (FPG). DESIGN AND SETTING: Cross-sectional study at Hospital do Servidor Público Estadual, São Paulo. METHODS: The FPG and glucose tolerance test (GTT) were analyzed, from which the subjects were divided as follows: group 1 (FPG and GTT both normal), group 2 (normal FPG but abnormal GTT), group 3 (abnormal FPG but normal GTT), and group 4 (FPG and GTT both abnormal). The subjects' clinical, laboratory and anthropometric profile was determined. RESULTS: 138 subjects were studied: 44 in group 1, 11 in group 2, 33 in group 3 and 50 in group 4. The prevalence of prediabetes was 68.0 percent. Group 4 individuals were older than group 1 individuals [69.0 (55.5-74.0) versus 58.9 ± 11.8 years; P < 0.05], with greater prevalence of risk conditions for DM [5.0 (4.0-5.0) versus 4.0 (3.0-5.0); P < 0.05]. Among individuals with normal FPG, GI prevalence was 20.0 percent. No variables analyzed correlated with GTT. CONCLUSION: The prevalence of prediabetes was 68.0 percent, and 20.0 percent of subjects with normal FPG had GI. Although some anthropometric, clinical and laboratory variables have been correlated with DM and prediabetes, none, except for GTT, was able to screen for GI among subjects with normal FPG in the present study.


CONTEXTO E OBJETIVO: Deve-se diagnosticar o estado pré-diabético precocemente para evitar as complicações do diabetes mellitus (DM). Objetiva-se avaliar a prevalência de estado pré-diabético entre indivíduos sob risco de desenvolvimento de DM, buscando variáveis relacionadas à intolerância à glicose (IG) naqueles com glicemia de jejum (GJ) normal. TIPO DE ESTUDO E LOCAL: Estudo transversal no Hospital do Servidor Público Estadual, São Paulo. MÉTODOS: Analisou-se GJ e teste oral de tolerância a glicose (GTT), que determinaram a seguinte divisão: grupo 1 (GJ e GTT normais), grupo 2 (GJ normal e GTT alterado), grupo 3 (GJ alterada e GTT normal) e grupo 4 (GJ e GTT alterados). Determinou-se o perfil clínico, laboratorial e antropométrico dos indivíduos estudados. RESULTADOS: Estudaram-se 138 indivíduos: 44 no grupo 1, 11 no grupo 2, 33 no grupo 3 e 50 no grupo 4. A prevalência de estado pré-diabético foi 68,0 por cento. Indivíduos do grupo 4, em relação ao grupo 1, demonstraram idade mais avançada [69,0 (55,5-74,0) versus 58,9 ± 11,8 anos, P < 0,05] e maior prevalência de condições de risco para o DM [5,0 (4,0-5,0) versus 4,0 (3,0-5,0), P < 0,05]. Dentre aqueles com GJ normal, 20,0 por cento apresentaram IG. Nenhuma variável se correlacionou com o GTT. CONCLUSÃO: A prevalência de estado pré-diabético foi 68,0 por cento; 20,0 por cento daqueles com GJ normal apresentaram IG. Apesar de algumas variáveis clínicas, antropométricas e laboratoriais estarem descritas como relacionadas ao DM e ao estado pré-diabético, no presente estudo, nenhuma, à exceção do GTT, foi capaz de rastrear a presença de IG entre aqueles com GJ normal.

ABSTRACT

Background: The prevalence obesity, type 2 diabetes (DM2) and glucose intolerance among children is increasing worldwide. Aim: To assess the frequency of DM2 and GI among severely obese children and adolescents. Patients and methods: Cross sectional study of 69 children and adolescents aged 12 +/- 3 years with a mean body mass index (BMI) z score of 2.9 +/- 0.6. An oral glucose tolerance test (OGTT) was performed, measuring fasting and 120 minutes blood glucose and insulin. According to these results two patients had diabetes mellitus and 4 had glucose intolerance. Previously studied patients, five with diabetes mellitus and two with glucose intolerance were incorporated to the present study. These 13 participants were compared with the remaining 63 children without abnormalities in glucose metabolism, considered as controls. Results: Body mass index among children with glucose intolerance, diabetes mellitus and controls was 33.8 +/- 6.4, 26.7 +/- 5.1 and 29.4 +/- 4.5 kg/m2, respectively, p = 0.03. Basal and 120 min insulin levels were also significantly higher among children with glucose intolerance compared with diabetics and controls. Homeostasis model assessment for insulin resistance was significantly lower in controls than in children with diabetes or glucose intolerance. Conclusions: Eight percent of this group of obese children and adolescents had DM2 or glucose intolerance. Oral glucose tolerance test should be included in the routine assessment of obese children to diagnose abnormalities of glucose metabolism.

ABSTRACT

CONTEXT: Cirrhosis, diabetes mellitus, impaired glucose tolerance, insulin resistance, and protein calorie malnutrition are important issues in cirrhotic patients because they can increase the progression of liver disease and worsen its prognosis. OBJECTIVE:To determine the prevalence of diabetes mellitus, impaired glucose tolerance and insulin resistance in cirrhotic patients being evaluated for liver transplantation and their impacts on a 3-month follow-up, and to compare fasting glycemia and oral glucose tolerance test. METHODS: A cross-sectional study was performed in consecutively included adult patients. Diabetes mellitus was established through fasting glycemia and oral glucose tolerance test in diagnosing diabetes mellitus in this population. HOMA-IR and HOMA-β indexes were calculated, and nutritional assessment was performed by subjective global assessment, anthropometry and handgrip strength through dynamometry. RESULTS: Diabetes mellitus was found in 40 patients (64.5 percent), 9 (22.5 percent) of them by fasting glycemia and 31 (77.5 percent) of them by oral glucose tolerance test. Insulin resistance was found in 40 (69 percent) of the patients. There was no relationship between diabetes mellitus and the etiology of cirrhosis. Protein calorie malnutrition was diagnosed in a range from 3.22 percent to 45.2 percent by anthropometry, 58.1 percent by subjective global assessment and 88.7 percent by handgrip strength. Diabetes mellitus identified by oral glucose tolerance test was related significantly to a higher prevalence of infectious complications and deaths in a 3-month period (P = 0.017). CONCLUSION: The prevalence of diabetes mellitus, impaired glucose tolerance, insulin resistance and protein calorie malnutrition is high in cirrhotic patients on the waiting list for liver transplantation. There were more infectious complications and/or deaths in a 3-month follow-up period in patients with diabetes mellitus diagnosed ...


CONTEXTO: Cirrose, diabetes mellitus, intolerância à glicose e resistência insulínica é uma associação que vem sendo discutida, bem como a desnutrição nesta população, pelo risco de pior evolução de hepatopatia. OBJETIVO: Determinar a prevalência de diabetes mellitus, intolerância à glicose e resistência insulínica e desnutrição protéico-calórica em cirróticos (vírus C+ ou -) candidatos a transplante hepático e avaliar a capacidade diagnóstica dos testes de diabetes mellitus e seu impacto na evolução em 3 meses. MÉTODOS: Estudo transversal prospectivo de pacientes consecutivos, com avaliação de diabetes mellitus por glicemia de jejum e/ou teste de tolerância oral à glicose, cálculo dos índices HOMA-IR e avaliação nutricional através da avaliação subjetiva global, antropometria e força do aperto de mão não-dominante. RESULTADOS: Sessenta e quatro virgula cinco por cento tinham diabetes mellitus, 9 (22,5 por cento) deles foram diagnosticados por glicemia de jejum e 31 (77,5 por cento) por tolerância oral à glicose. A resistência insulínica foi encontrada em 40 pacientes (69 por cento). Não houve relação com a causa da cirrose. A desnutrição protéico-calórica foi encontrada em 3,22 por cento dos pacientes através do índice de massa corporal, 45,2 por cento por antropometria, 58,1 por cento pela avaliação subjetiva global e 88,7 por cento pela força do aperto de mão não-dominante. Houve associação entre diabetes mellitus diagnosticado pelo teste de tolerância oral à glicose e a maior prevalência de complicações infecciosas e/ou morte em 3 meses (P = 0,017). CONCLUSÃO: A prevalência de diabetes mellitus, intolerância à glicose, resistência insulínica e desnutrição protéico-calórica é alta em cirróticos em lista de transplante hepático. A evolução em 3 meses é pior quando há diabetes mellitus. O teste de tolerância oral à glicose teve rendimento superior à glicemia de jejum no diagnóstico de diabetes mellitus. Sugere-se o emprego rotineiro ...

ABSTRACT

OBJECTIVES: This study was performed to investigate the prevalence of impaired fasting glucose (IFG) and its related characteristics among healthy adults in some Korean rural areas. METHODS: We conducted a cross-sectional study using the data from 1352 adults who were over the age 40 and under the age 70 and who were free of diabetes mellitus (DM), cardiovascular diseases and other diseases and who participated in a survey conducted as part of the Korean Rural Genomic Cohort Study. IFG was defined as a serum fasting glucose level between 100 and 125 mg/dL. RESULTS: The prevalence of IFG was 20.4% in men, 15.5% in women and 12.7% overall. Multivariate logistic regression analysis demonstrated that the independent risk factors for IFG were male gender, having a family history of DM, the quartiles of gamma glutamyltransferase and high sensitive C-reactive protein and the waist circumference. The homeostatis model assessment for insulin resistance was very strongly associated with IFG. The prevalence of metabolic syndrome (MS) and MS components was higher in the subjects with IFG then in those with normal fasting glucose (NFG). CONCLUSIONS: The result of study could supply evidence to find the high risk population and to determine a strategy for treating IFG. Further research is needed to explain the causal relationship and mechanisms of IFG.

ABSTRACT

Introdução: Cerca de 20% dos adolescentes com fibrose cística têm diabetes melito (DM) relacionado à fibrose cística (FC). O teste oral de tolerância à glicose (TOTG) tem sido utilizado para identificar alterações no metabolismo da glicose. Objetivo: O objetivo deste estudo foi identificar as alterações no metabolismo da glicose em crianças e adolescentes com FC e descrever as características clínicas e laboratoriais relacionadas à tolerância diminuída à glicose (TDG) e DM nesse grupo de pacientes. Pacientes e métodos: Foi realizado um estudo transversal envolvendo crianças e adolescentes com diagnóstico de FC em atendimento no Hospital de Clínicas de Porto Alegre. TOTG com glicose na dose de 1,75 g/kg de peso com dose máxima de 75 g foi realizado. Resultados: No total foram avaliados 58 pacientes (1,9-16,9 anos). TDG foi encontrada em 6 pacientes e presença de DM em 1, todos acima de dez anos de idade. Estes 7 pacientes foram comparados com os outros 29 pacientes de mesma faixa etária com TOTG normal. Os pacientes com o TOTG alterado eram mais velhos (14±1,2 vs. 10,6±4 anos, P<0,001), apresentaram maior tempo de duração da FC (13±2,6 vs. 9±4 anos, P<0,0006) e apresentaram maior número de internações (6 [5-16] vs. 3 [1,5-8,5], P<0,029). Conclusão: Neste estudo foi observada uma prevalência de alteração da tolerância à glicose de 12% em crianças e adolescentes com FC.


Background: About 20% of adolescents with cystic fibrosis (CF) present diabetes related to this condition. The oral glucose tolerance test (OGTT) has been used to identify alterations in glucose metabolism in these patients. Aim: The aim of this study was to identify changes in glucose metabolism in children and adolescents with CF and to describe the clinical and laboratory characteristics related to impaired glucose tolerance (IGT) and diabetes. Patients and methods: This was a cross-sectional study involving children and adolescents with cystic fibrosis (CF). An OGTT with 1.75 g glucose/kg - max 75 g was performed. Results: Fifty-eight individuals (1.9-16.9 years) were evaluated. IGT was found in six and diabetes in one; all were older than 10 years. These 7 patients were compared to the 29 with normal OGTT with the same age. The patients with altered OGTT were older (14±1.2 vs 10.6±4years, P<0.001), had longer FC duration (13±2.6 vs. 9±4 years, P<0.006), and had a higher number of hospitalizations (6 [5-16] vs 3[1.5- 8.5], P<0.029). Conclusion: In this study the prevalence of impaired glucose tolerance was 12% in children and adolescents with CF.

ABSTRACT

OBJETIVO: Estimar a prevalência de diabetes melito (DM) e tolerância à glicose diminuída (TGD) na população urbana de 30 a 79 anos da cidade de São Carlos, São Paulo. MÉTODOS: Foi realizado estudo de base populacional entre agosto de 2007 e junho de 2008. Todos os indivíduos, exceto mulheres grávidas, não diabéticos e aqueles com glicemia capilar em jejum < 199 mg/dl foram submetidos a teste oral de tolerância à glicose e classificados em diabéticos, com TGD ou com tolerância normal à glicose. RESULTADOS: Participaram da pesquisa 1.116 voluntários. As prevalências gerais de DM e TGD foram 13,5 por cento e 5 por cento, respectivamente. Houve associação entre DM e TGD e as variáveis "idade", "escolaridade", "índice de massa corpórea" e "circunferência abdominal". Não houve associação entre DM ou TGD e as variáveis "gênero", "cor da pele" e "rendimento mensal". CONCLUSÕES: Houve aumento na prevalência de DM em comparação a estudos anteriores no Brasil e na região. Embora tenha havido avanços no diagnóstico, o tratamento do DM requer otimização.


OBJECTIVE: To assess the prevalence of diabetes mellitus (DM) and impaired glucose tolerance (IGT) in the urban population aged 30-79 years of the city of São Carlos, São Paulo, Brazil. METHODS: It was performed a population survey, from August 2007 to June 2008. Non diabetic individuals, excluding pregnant women, and those with fasting capillary glycemia < 199 mg/dl were administered oral glucose tolerance test and classified as diabetic, with IGT or with normal glucose tolerance. RESULTS: The number of individuals who participated in the study was 1,116. The overall rates of DM and IGT were 13.5 percent and 5 percent, respectively. DM and IGT were associated with age, education, body mass index and waist. They were not associated with gender, race or income. CONCLUSIONS: The prevalence of DM has increased when compared with previous studies in Brazil and in the state. Improvement in the diagnosis has occurred, however, treatment requires optimization.

ABSTRACT

AIMS AND OBJECTIVES: The aim of this study was to estimate the prevalence of diabetes as well as IFG in a population of policemen and to evaluate the possible influence of some risk factors. MATERIAL AND METHODS: It was an epidemiological study on a group of policemen in Kolkata. Diagnosis of diabetes was based on history and fasting plasma glucose. The study population was divided in three categories: normoglycaemic, IFG and diabetes. BMI, waist circumference, WHR and waist-to-height ratio were estimated. RESULTS: Out of 2160 subjects with a mean age of 36.4 yrs (between 20 and 60 yrs), diabetes was found in 11.5% (10.4% known and 1.1% newly diagnosed) and 6.2% had IFG. Prevalence of diabetes was found to be increasing with age (p < 0.001). There was no statistically significant difference in BMI when compared between groups (normoglycaemic, IFG and diabetes). Waist circumference, waist-to-height ratio and WHR of normoglycaemic group were significantly less than those with IFG and diabetes; however there was no statistically significant difference between the diabetes and IFG groups. Parental history had significant influence on the prevalence of diabetes; a 37.5% prevalence was found in persons with history of biparental diabetes and 20.8% with uniparental diabetes, whereas it was only 9.9% without any family history (p < 0.01 and p < 0.05, respectively.). CONCLUSION: The prevalence of diabetes in the study population was high and was strongly influenced by family history, age and abdominal adiposity, without having any appreciable impact of BMI.

ABSTRACT

OBJETIVOS: Determinar a prevalência do diabetes melito (DM) e da hiperglicemia de estresse (HE) em pacientes com infarto agudo do miocárdio (IAM) admitidos em unidade de emergência cardiológica. MÉTODOS: Análise retrospectiva de 2.262 pacientes com IAM, avaliando, além da prevalência de diabetes referido, o diagnosticado e a hiperglicemia de estresse. RESULTADOS: Apesar de referido em 12,1 por cento dos pacientes (H: 10,7 por cento, M: 15,8 por cento), o DM ocorria efetivamente em 24,8 por cento (H: 22,9 por cento, M: 29,7 por cento) e a HE em 13,6 por cento (H: 14,3 por cento, M: 11,7 por cento) dos indivíduos dessa população. Portanto, alterações glicêmicas ocorreram em 37,4 por cento dos indivíduos com IAM (H: 37,2 por cento, M: 41,4 por cento). Nos pacientes com DM, observou-se maior precocidade etária do IAM, maior prevalência de óbitos (DM: 20,7 por cento, ND:13,8 por cento, HE: 13,4 por cento) e de procedimentos cirúrgicos (ND: 33,8 por cento, HE: 18,0 por cento, DM: 21,7 por cento). CONCLUSÃO: A elevada prevalência de DM e hiperglicemia de estresse observada em nosso estudo indica que as alterações glicêmicas constituem um dos mais importantes fatores de risco para o IAM.


OBJECTIVES: To evaluate in our population the real prevalence of diabetes (DM) and stress hyperglycemia (HE) in patients with myocardial infarction (IAM) admitted in a cardiologic emergency unit. METHODS: A retrospective analysis of 2262 patients with AMI evaluating the prevalence of DM (referred and diagnosed) and stress hyperglycemia. RESULTS: Besides 12,1 percent of subjects were previously referred to be diabetic (men: 10.7 percent and women: 15.8 percent), diabetes was effectively diagnosed in 24,8 percent (M: 22,9 percent, W: 29,7 percent) and stress hyperglycemia in 13,6 percent HE of the patients (M: 14,3 percent, W: 11,7 percent) indicating that glycemic alterations were effectively observed in 37.2. percent of the patients with IAM (M: 37,2 percent, W: 41,4 percent). In DM subjects IAM events occurred earlier, total intra-hospital mortality was higher (DM: 20.7 percent, ND: 13,8 percent, HE: 13,4 percent) and less surgical procedures were performed (ND 33.8 percent, DM: 21.7 percent, HE: 18.0 percent). CONCLUSION: The elevated DM and stress hyperglycemia prevalence observed in our study indicates that glycemic alterations is one of the most important risk factors for IAM.

ABSTRACT

Evidence suggests that risk of chronic diseases may be programmed during the foetal and early life of the infant. With high rates of low birthweight coupled with a rapid nutritional transition, low-income countries are facing an epidemic of chronic diseases. Follow-up of a cohort of adults born during 1964-1978 in an urban slum in Lahore, Pakistan, is presented in this paper. In 695 of these adults (mean age=29.0 years, males=56%), blood pressure, fasting blood glucose, and body mass index (BMI) were measured to assess early-life predictors of risk of chronic diseases. Sixteen percent of the study population was born with a low birthweight (<2,500 g). A significant positive association (p=0.007) was observed between birthweight and BMI; additionally, adjusting for age and gender, the association with BMI was highly significant (p=0.000). Conversely, a significant negative association (p=0.016) was observed between birthweight and adult levels of fasting plasma glucose; after adjustment for age and gender, the association was more significant (p=0.005) No association was observed between birthweight and adult blood pressure. The results suggest that low birthweight may increase later risk of impaired glucose tolerance in urban Pakistani adults. Further research in this area is warranted.

ABSTRACT

INTRODUÇÃO: O Diabetes mellitus (DM) é um grave e crescente problema de saúde pública no mundo, sobretudo nos países em desenvolvimento. O Brasil apresenta prevalência alta (7,6 por cento), semelhante à de países mais desenvolvidos. OBJETIVO: Estimar a prevalência de DM nos policiais do sexo masculino, em serviço ativo de Teresina, Piauí. METODOLOGIA: Foi realizado um estudo seccional em uma amostra aleatória 484 policiais do sexo masculino, com 30 a 59 anos de idade, lotados em Teresina. Os selecionados responderam a uma entrevista que contemplava variáveis relativas a identificação, dados demográficos e condições de saúde. Os indivíduos que apresentaram glicemia capilar abaixo de 100 mg/dl foram considerados normais, aqueles entre 100 e 125mg/dl foram submetidos ao teste de tolerância oral a glicose, os com resultado entre 126 e 199mg/dl fizeram glicemia plasmática e os que apresentaram níveis mais elevados foram encaminhados para uma consulta médica. Foram mensurados peso, altura e circunferência abdominal.RESULTADOS: A glicemia capilar apresentou níveis normais em 64,5 por cento, valores entre 100 e 125 mg/dl em 28,7 por cento, entre 126 e 199 mg/dl em 5,5 por cento e acima de 200 mg/dl em 1,3 por cento da amostra analisada. O inquérito detectou 28 diabéticos, sendo que 11 já se sabiam diabéticos e faziam tratamento (2,3 por cento), enquanto 17 (3,5 por cento) foram diagnosticados pelo estudo, resultando em uma prevalência de DM de 5,8 por cento e de Tolerância Diminuída à Glicose de 8,0 por cento. A análise de potenciais fatores de risco para DM mostrou associação direta da prevalência com a idade e inversa com a escolaridade, ambas estatisticamente significativas. A regressão logística apontou que a probabilidade de ser diabético aumentava em 10 por cento a cada acréscimo de 1 ano na idade e era 3,7 vezes maior nos que tinham menos de 8 anos de estudo do que naqueles que tinham maior escolaridade, independente da idade. CONCLUSÃO: Os resultados subsidiam a implantação de medidas e ações preventivas no controle da doença, com a finalidade de impedir seu aparecimento e complicações.

ABSTRACT

The aim of this study was to determine the prevalences of diagnosed and undiagnosed diabetes mellitus, impaired fasting glucose [IFG], impaired glucose tolerance [IGT], and combined IFG/IGT and to develop an effective screening strategy for undiagnosed diabetes in a large urban Iranian community. The study population included 9,519 participants of the Tehran Lipid and Glucose Study, aged > 20 years, with full relevant clinical data. Age-standardized prevalence of diabetes and glucose intolerance categories were reported according to the 2003 American Diabetes Association definitions. The numbers needed to screen [NNTS] to find one person with undiagnosed diabetes were estimated from age-adjusted logistic regression models. The prevalences of diagnosed and undiagnosed diabetes, isolated IFG, isolated IGT, and combined IFG/IGT were 8.1%, 5.1%, 8.7%, 5.4% and 4.0% in men and 10%, 4.7%, 6.3%, 7.6%, and 4.5% in women respectively. Un-diagnosed diabetes was associated with family history of diabetes, increased body mass index [BMI >/= 25 kg/m2], abdominal obesity, hypertriglyceridemia, hypertension and low HDL-C levels. Among men, a combination of increased BMI, hypertension, and family history of diabetes led to an NNTS of 1.6 [95%CI: 1.57-1.71] and among women a combination of family history of diabetes and abdominal obesity, yielded an NNTS of 2.2 [95%CI: 2.1-2.4]. Approximately 32% of Tehranian adults had either diabetes or some degree of other glucose tolerance abnormalities. Nearly 40% of total cases with diabetes were undiagnosed. Screening individuals with family history of diabetes, BMI25 kg/m2, abdominal obesity and hypertension may have substantial advantages

ABSTRACT

Thalassemia major is a genetic disorder. Blood transfusion is critical for survival in these patients. Over the course of the past two and three decade's hyper transfusion therapy in these patients has increased significant improvement in life expectancy and quality of life. Unfortunately this type of therapy increased the frequency of complication due to iron overloud. The aim of this study was to evaluate the prevalencey of diabetes, impaired fasting glucose and impaired glucose tolerance in patients with thalassemia major, with 10-27 years of age in Tabriz. This descriptive study was done on 56 patients between 10-27 years of age with thalassemia major. The demographic informaiton theraputic regiment, the age of first trasfussion. The level of blood transfusion, the history and dosage of familial history of diabetes, Fe, TIBC, ferritin levels were assessed and recorded. For each patient glucose tolerance test, blood glucose level are performed. In this study prevalence of diabetes mellitus, impaired fasting glucose and impaired glucose tolerance test were found in 8.9%, 28.6% and 7.1% of patients respectively. This study showed that despite recent therapy with Desferal in the management of beta-thalassemia major, the risk of secondary endocrine dysfunction remains high. Prevalence of diabetes mellitus, impaired fasting glucose and impaired glucose tolerance test are greater than general population. Endocrine evaluation in patients with thalassemia major must be carried out regularly especially in those patients over the age of 10 years

ABSTRACT

AIMS: This analysis was done to compare the risk of development of diabetes among subjects with impaired glucose tolerance (IGT) and early glucose intolerance (EGI; intermediary post glucose level > or = 160 mg/dl) when compared with normal (NGT). Profile of insulin secretion and insulin resistance was compared in a subgroup of subjects with EGI, IGT and diabetes. PATIENTS AND METHODS: A program on 'primary prevention of diabetes' was initiated and high risk subjects were encouraged to join the program and were followed up. Out of 4084 (M:F 2344:1740) subjects enrolled in the program, a total of 1659 (M:F 1044:615) subjects with mean age 41.3 +/- 10.2 years who had at least two follow up visits were selected for this analysis. OGTTs were performed once in every 6 months. The median follow up duration was 5 years. The conversion rate to diabetes in subjects with persistent IGT or EGI was determined. In a subgroup of subjects, NGT (n = 118), IGT (n = 68), EGI (n = 106) and new DM (n = 126), plasma insulin at fasting, 30 min and 2 hr were measured and insulin resistance (HOMA-IR) was calculated by HOMA method. Insulinogenic index (DeltaI/G) was also calculated. RESULTS: The rate of conversion of IGT 251 (40.5%) and EGI 210 (36.5%) subjects to diabetes was similar and significantly higher when compared with the NGT subjects 99 (21.3%). Similar results were noted both in men and women. By using ROC procedure, a cut - off value of one hour post glucose of > or = 160 mg/dl gave a sensitivity of 80% and specificity of 70% to detect abnormal glucose tolerance. In a subset of subjects studied, it was noted that subjects with EGI had significantly higher fasting insulin values than NGT. Insulin resistance (IR) was the highest in DM [Geometric mean (SD)] 6.6 (1.9)), followed by EGI (4.5 (2.3)) (p < 0.0001 vs NGT, 2.9 (2.4)) and IGT (3.9 (2.2)). Insulinogenic index was normal in EGI, NGT and IGT, and it was lower in DM in comparison with other groups. The multiple logistic regression analysis showed that EGI (odds ratio (OR) 2.11) and development of diabetes was strongly associated. The survival curve (time free from diabetes) showed that the median survival time for NGT, EGI and IGT were 18.7, 11.6 and 9.6 yrs respectively. CONCLUSION: EGI which is a distinct entity with abnormal intermediate glucose response in glucose tolerance test (GTT) appears to be a risk factor similar to IGT in the development of diabetes. They had higher insulin resistance with normal insulin secretion. Therefore, it is important to determine the intermediate value also during the GTT in addition to fasting and 2 hr post glucose values.
