ABSTRACT

ABSTRACT Introduction Diabetes is a metabolic disease characterized by hyperglycemia. It is a metabolic syndrome in which blood sugar levels increase due to defects in insulin secretion or impaired function, or even both defects. Object To understand the effect of diabetic patients in controlling blood sugar through physical exercise, the paper analyzes the correlation between the exercise status and physiological indicators of diabetic patients in our hospital. Methods We randomly selected 41 diabetic patients and monitored their exercise. At the same time, we check the physiological indicators of the patients after the exercise is completed and analyze the control of blood sugar by sports. Results After healthy physical exercise, the blood sugar level of diabetic patients tended to stabilize, and the glycosylated hemoglobin level decreased. The blood sugar levels of patients who did not participate in healthy physical exercises were not stable, and their glycosylated hemoglobin levels did not improve. Conclusion Healthy sports is a simple, easy, safe and effective adjuvant therapy for the prevention and treatment of diabetes, and it is worthy of clinical promotion. Level of evidence II; Therapeutic studies - investigation of treatment results.


RESUMO Introdução O diabetes é uma doença metabólica caracterizada por hiperglicemia. É uma síndrome metabólica em que os níveis de açúcar no sangue aumentam devido a defeitos na secreção de insulina ou função prejudicada, ou mesmo ambos os defeitos. Objetivo Para compreender os pacientes diabéticos no controle da glicemia por meio do exercício físico, o artigo analisa a correlação entre o estado de exercício e os indicadores fisiológicos de pacientes diabéticos em nosso hospital. Métodos Selecionamos aleatoriamente 41 pacientes diabéticos e monitoramos seus exercícios. Ao mesmo tempo, verificamos os indicadores fisiológicos dos pacientes após a realização do exercício e analisamos o controle da glicemia pelo esporte. Resultados Após exercícios físicos saudáveis, o nível de açúcar no sangue de pacientes diabéticos tendeu a se estabilizar e o nível de hemoglobina glicosilada diminuiu. Os níveis de açúcar no sangue dos pacientes que não praticavam exercícios físicos saudáveis não foram estáveis e os níveis de hemoglobina glicosilada não melhoraram. Conclusão O esporte saudável é uma terapia adjuvante simples, fácil, segura e eficaz para a prevenção e tratamento do diabetes e merece divulgação clínica. Nível de evidência II; Estudos terapêuticos - investigação dos resultados do tratamento.

ABSTRACT

Objective@#The relationship between serum uric acid (SUA) levels and glycemic indices, including plasma glucose (FPG), 2-hour postload glucose (2h-PG), and glycated hemoglobin (HbA1c), remains inconclusive. We aimed to explore the associations between glycemic indices and SUA levels in the general Chinese population.@*Methods@#The current study was a cross-sectional analysis using the first follow-up survey data from The China Cardiometabolic Disease and Cancer Cohort Study. A total of 105,922 community-dwelling adults aged ≥ 40 years underwent the oral glucose tolerance test and uric acid assessment. The nonlinear relationships between glycemic indices and SUA levels were explored using generalized additive models.@*Results@#A total of 30,941 men and 62,361 women were eligible for the current analysis. Generalized additive models verified the inverted U-shaped association between glycemic indices and SUA levels, but with different inflection points in men and women. The thresholds for FPG, 2h-PG, and HbA1c for men and women were 6.5/8.0 mmol/L, 11.0/14.0 mmol/L, and 6.1/6.5, respectively (SUA levels increased with increasing glycemic indices before the inflection points and then eventually decreased with further increases in the glycemic indices).@*Conclusion@#An inverted U-shaped association was observed between major glycemic indices and uric acid levels in both sexes, while the inflection points were reached earlier in men than in women.

ABSTRACT

ABSTRACT Objectives: Our study aimed to investigate the associations of glucose tolerance status with insulin-like growth factor-I (IGF-I) and other clinical laboratory parameters of acromegalic patients before and after the patients underwent transsphenoidal adenomectomy (TSA) by conducting a single-center, retrospective study. Subjects and methods: A total of 218 patients with acromegaly who had undergone TSA as the first treatment were retrospectively analyzed. Serum IGF-I, growth hormone (GH) and glucose levels were measured before and after surgery. Results: The follow-up levels for random GH, GH nadir, and the percentage of the upper limit of normal IGF-I (%ULN IGF-I) were decreased significantly. The percentages of normal (39.0%), early carbohydrate metabolism disorders (33.0%) and diabetes mellitus (28.0%) changed to 70.2%, 16.5% and 13.3%, respectively, after TSA. %ULN IGF-I at baseline was higher in the diabetes mellitus (DM) group than in the normal glucose tolerance group and impaired glucose tolerance (IGT) /impaired fasting glucose (IFG) groups before TSA, and the DM group exhibited a greater reduction in %ULN IGF-I value after surgery. The follow-up %ULN IGF-I value after surgery was significantly lower in the improved group, and Pearson's correlation analysis revealed that the reductions in %ULN IGF-I corresponded with the reductions in glucose level. Conclusion: This study examined the largest reported sample with complete preoperative and follow-up data. The results suggest that the age- and sex-adjusted IGF-I level, which reflects altered glucose metabolism, and the change of it are associated with improved glucose tolerance in acromegalic patients both before and after TSA.

ABSTRACT

Abstract Objective: The diabetic population has a high prevalence of coronary artery disease, and frequently patients with diabetes undergo coronary artery bypass graft (CABG) surgery. Elevated glycated hemoglobin (HbA1c) in diabetics is shown to be associated with morbidity and mortality, but the association of HbA1c with postoperative length of hospital stay (LOS) has conflicting results. In this study, we aim to identify if elevated HbA1c levels are associated with prolonged LOS after CABG surgery. Methods: A retrospective chart review study was performed, using a total of 305 patients who were referred for CABG surgery. HbA1c levels were measured before the day of surgery. Patients were classified into two groups according to HbA1c levels: <7% and ≥7%. A LOS of more than 14 days was proposed as an extended LOS. HbA1c and the LOS relationship were assessed using appropriate statistical methods. Results: Patients who had diabetes mellitus comprised 81.6% of our studied population. Sixty-four percent had HbA1c levels ≥ 7%. There was no significant difference in the total LOS in HbA1c <7% compared to HbA1c ≥7% patients (P=0.367). Conclusion: Our study results rejected the proposed hypothesis that elevated HbA1c levels ≥7% would be associated with prolonged hospital stay following CABG surgery in a Saudi population.

ABSTRACT

SUMMARY Obesity, diabetes and hypertension are risk factors for cardiovascular diseases (CVD) because they promote a state of hypercoagulability. It is known that platelets play an important role in the development of atherosclerosis. Recent studies have evaluated platelet volume indexes (PVIs) in individuals with risk factors for CVD to better understand the platelet mechanisms involved in their development. The IVPs indirectly estimate platelet function and are easily obtained from automated hematology analyzers, which provide platelet counts, mean platelet volume (MPV), platelet distribution width (PDW) and the platelet-large cell ratio (P-LCR). The present study aims to review literature studies that investigated the association between PVIs and obesity, diabetes, and arterial hypertension, in order to evaluate its use as a potential subclinical marker of CVD. Studies have shown promising results for MPV, an index that allows for early detection of platelet activation and may be useful in identifying patients before the onset of CVD development so that preventive strategies can be implemented. The PDW, although evaluated by a smaller number of studies, also showed promising results. However, there is still a long way to go in order for the MPV and PDW to be used in clinical practice, since there is still a need for more epidemiological evidence, establishing reference values, and standardizing the way results are presented.


RESUMO A obesidade, o diabetes e a hipertensão arterial são fatores de risco para as doenças cardiovasculares (DCV) por promoverem um estado de hipercoagulabilidade. É sabido que as plaquetas desempenham um importante papel no desenvolvimento da aterosclerose. Diante disso, estudos recentes têm avaliado os índices de volumes plaquetários (IVPs) em indivíduos com fatores de risco para DCV, para melhor se entenderem os mecanismos plaquetários envolvidos no seu desenvolvimento. Os IVPs estimam indiretamente a função plaquetária e são facilmente obtidos a partir de analisadores hematológicos automáticos, que fornecem contagens de plaquetas, volume médio de plaquetas (VPM), largura de distribuição de plaquetas (PDW) e a proporção de plaquetas grandes (P-LCR). O presente trabalho tem por objetivo revisar na literatura estudos que investigaram a associação entre os IVPs e obesidade, diabetes e hipertensão arterial, a fim de avaliar o seu uso como potencial marcador subclínico das DCV. Estudos demonstraram resultados promissores quanto ao VPM, um índice que permite uma detecção precoce da ativação de plaquetas e que pode ser útil na identificação de pacientes antes do início do desenvolvimento de DCV, de tal forma que estratégias preventivas possam ser implantadas. O PDW, embora tenha sido avaliado por um número menor de estudos, também demonstrou resultados promissores. Entretanto, ainda existe um longo caminho a se percorrer para que o VPM e o PDW sejam utilizados na prática clínica, pois ainda são necessárias mais evidências epidemiológicas, o estabelecimento de valores de referência e a padronização da forma de expressar os resultados.

ABSTRACT

Abstract The aim of this study was to investigate salivary levels of TGFβ1 and proliferation/ maturation of epithelial mucosa cells in diabetic and hypertensive patients. Design: in this cross-sectional study, whole stimulated saliva and oral mucosa exfoliative cytology specimens were collected from 39 patients that were healthy (control, n=10) or presented history of arterial hypertension (HAS, n=9), diabetes mellitus (DM, n=10) or both (DM+HAS, n=10). Salivary flow rate (SFR), TGFβ1 level in saliva, AgNORs and the epithelial maturation were evaluated. Non-parametric Kruskal-Wallis test, followed by Dunn's multiple comparison post-test and the Spearman test correlation analysis were used. SFR showed a significant decreased in DM and DM+HAS (0.47±0.11 and 0.64±0.43 mL/min) when compared to control (1.4±0.38 mL/min). DM+HAS presented the highest value of TGFβ1 concentration (24.72±5.89 pg/mL). It was observed a positive correlation between TGFβ1 and glycaemia (R=0.6371; p<0.001) and a negative correlation between TGFβ1 and saliva (R=-0.6162; p<0.001) and glycaemia and SFR (R=-0.5654; P=0.001). AgNORs number and status of maturation of mucosa cells were similar for all conditions. DM and DM+HAS presented the lowest SFR, which correlated with increased TGFβ1 levels. Despite the higher TGFβ1 secretion it was not observed changes in the morphology or proliferation of epithelial cells when diabetes or hypertension was present.


Resumo O objetivo deste estudo foi investigar os níveis de TGFβ1 na saliva e a proliferação/maturação das células epiteliais da mucosa em paciente diabéticos e hipertensos. Neste estudo transversal, saliva estimulada e amostras de citologia exfoliativa de mucosa oral foram coletadas de um total de 39 pacientes que se apresentavam saudáveis (controle, n=10) ou com história de hipertensão arterial (HAS, n=9), diabetes mellitus (DM, n=10) ou ambos (DM+HAS, n=10). Taxa de fluxo salivar (SFR), níveis de TGFβ1 na saliva, AgNORs e maturação epitelial foram avaliados. Teste não-paramétrico de Kruskal-Wallis, seguido de comparação múltipla de Dunn e correlação de Spearman foram utilizados para as análises. SFR diminuiu significantemente em DM e DM+HAS (0,47±0,11 e 0,64±0,43 mL/min) quando comparado ao controle (1,4±0,38 mL/min). DM+HAS apresentou os maiores valores de concentração de TGFβ1 (24,72±5,89 pg/mL). Foi observada uma correlação positiva entre TGFβ1 e glicemia (R=0,6371; p<0,001) e uma correlação negativa entre TGFβ1 e saliva (R=-0,6162; p<0,001) e glicemia e SFR (R=-0,5654; p=0,001). Número de AgNORs e o padrão da maturação das células epiteliais foram similares entre os todos grupos. DM e DM+HAS apresentaram os menores valores de SFR, os quais foram correlacionados com o aumento nos níveis de TGFβ1. Apesar da maior secreção de TGFβ1, não foram observadas mudanças na morfologia ou proliferação das células epiteliais quando o paciente apresentava diabetes ou hipertensão.

ABSTRACT

PURPOSE: We investigated associations between family history of diabetes (FHD) and hemoglobin A1c (HbA1c) level, among people with and without diabetes. MATERIALS AND METHODS: In total, 7031 people without diabetes and 1918 people with diabetes who participated in the Dong-gu Study were included. Data on FHD in first-degree relatives (father, mother, and siblings) were obtained. Elevated HbA1c levels in people without diabetes and high HbA1c levels in people with diabetes were defined as the highest quintiles of HbA1c ≥5.9% and ≥7.9%, respectively. RESULTS: In people without diabetes, the odds of elevated HbA1c levels [odds ratio (OR) 1.34, 95% confidence interval (CI) 1.13−1.59] were significantly greater in people with any FHD than in those without. Specifically, the odds of elevated HbA1c levels in people without diabetes with an FHD involving siblings were greater than in those without an FHD involving siblings. Additionally, in people with diabetes, the odds of high HbA1c levels (OR 1.33, 95% CI 1.02−1.72) were greater in people with any FHD than in those without such history. Moreover, people with diabetes with maternal FHD had increased odds of high HbA1c levels. CONCLUSION: FHD was associated not only with high HbA1c levels in people with diabetes, but also with elevated HbA1c levels in people without diabetes.

ABSTRACT

ABSTRACT Diabetes mellitus (DM) is a chronic and metabolic disease that presents a high global incidence. Glycated hemoglobin (A1C) is the reference test for long-term glucose monitoring, and it exhibits an association with diabetic chronic complications. However, A1C is not recommended in clinical situations which may interfere with the metabolism of hemoglobin, such as in hemolytic, secondary or iron deficiency anemia, hemoglobinopathies, pregnancy, and uremia. The glycated albumin (GA) is a test that reflects short-term glycemia and is not influenced by situations that falsely alter A1C levels. GA is the higher glycated portion of fructosamine. It is measured by a standardized enzymatic methodology, easy and fast to perform. These laboratory characteristics have ensured the highlight of GA in studies from the last decade, as a marker of monitoring and screening for DM, as well as a predictor of long-term outcomes of the disease. The aim of this review was to discuss the physiological and biochemistry characteristics of the GA, as well as its clinical utility in DM.

ABSTRACT

Background: Structured educative programs have demonstrated their usefulness as a strategy to improve metabolic control in diabetic patients. Aim: To evaluate the effectiveness of a structured educative program for Chilean diabetic patients. Material and Methods: A randomized clinical trial in diabetic patients with glycosylated hemoglobin over 7.5%. One hundred fifteen patients were studied, 59 patients participated in the structured educative program (experimental group) and 56 patients received no structured education (control group). Patients were followed for 12 months. Results: Between baseline and 12 months of follow-up, glycosylated hemoglobin changed from 10.05 to 9.11% in experimental patients and from 9.86 to 9.25% in controls. No significant differences between experimental and control groups in other clinical and metabolic parameters were observed. In the experimental group, glycosylated hemoglobin reductions differed among the different educators who carried out the program. Conclusions: A structured educative program resulted in a 35% greater reduction in glycosylated hemoglobin levels, compared with a control group. Metabolic control improvement differed between the educators who carried out the program.

ABSTRACT

OBJECTIVES: To analyse the frequency of metabolic syndrome in young adult female dermatomyositis patients and its possible association with clinical and laboratory dermatomyositis-related features and serum adipocytokines. METHOD: This cross-sectional study included 35 dermatomyositis patients and 48 healthy controls. Metabolic syndrome was defined according to the 2009 Joint Interim Statement. RESULTS: Patient age was comparable in the dermatomyositis and control groups, and the median disease duration was 1.0 year. An increased prevalence of metabolic syndrome was detected in the dermatomyositis group (34.3% vs. 6.3%; p=0.001). In addition, increased serum adiponectin and resistin levels were noted in contrast to lower leptin levels. In dermatomyositis patients, adipocytokine levels were correlated with the levels of total cholesterol, low-density cholesterol, triglycerides and muscle enzymes. A comparison of dermatomyositis patients with (n=12) and without (n=23) syndrome metabolic revealed that adipocytokine levels were also correlated with age, and that dermatomyositis patients with metabolic syndrome tended to have more disease activity despite similar adipocytokine levels. CONCLUSIONS: Metabolic syndrome is highly prevalent in young adult female dermatomyositis patients and is related to age and disease activity. Moreover, increased serum adiponectin and resistin levels were detected in dermatomyositis patients, but lower serum leptin levels were observed.

ABSTRACT

ABSTRACT Objective The goal of this study was evaluate the conicity index (C index) in women and its association with hypertension (SAH) and diabetes mellitus (DM). Subjects and methods This was a cross-sectional study, with 573 women between 20 and 59 years of age. After analysis of clinical and demographic characteristics, anthropometric variables were measured and used to calculate the C index. Plasma glucose and lipid profile were evaluated by standard methods. The analysis of the results was based on logistic regression and the odds ratio (OR) was calculated, which was used to assess the association of the variable outcome with the variable exposure using two logistic regression models that tested the possible influence of the C index in the chance of developing SAH or DM. A confidence interval of 95% was used. Results In the crude and adjusted models, the OR confirmed the association of the C index with DM and SAH. Compared with women that showed C index p < 75, the risk of women with C index (p ≥ 75) developing DM and SAH was 1.72 and 1.75, respectively. Results demonstrated that the negative impact of age on these associations significantly raised the odds of women having DM and SAH. The high C index was also linked to low HDL-C. Conclusion The C index is an important tool in estimating the risk of diabetes and hypertension in women. Besides, high C indexes are negatively associated with HDL-C, an important lipid marker related to cardiovascular risk.

ABSTRACT

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.

ABSTRACT

A glicação não enzimática das proteínas é um fator comum para a fisiopatologia de uma série de transtornos relacionados ao envelhecimento e a doenças como o diabetes mellitus (DM). O geração dos produtos de glicação, os AGEs (do inglês: Advanced Glycation End Products) se dá através de reações de glicação da mariz extracelular (MEC) na derme e têm sido apontado como um dos fatores responsáveis pela perda de elasticidade e deficiência de cicatrização da pele. A permeação cutânea de compostos anti-AGE é uma limitação importante para eficiência terapêutica de compostos que devem atingir camadas mais profundas da pele. Modelos de pele reconstruída contendo equivalente dérmico glicado são estruturas tridimensionais geradas in vitro que mimetizam a pele humana e representam um eficiente modelo para o estudo de células e modificações provocadas na MEC no processo de envelhecimento e DM. O modelo 3D de pele reconstruída tem características metabólicas, de permeabilidade e atividade semelhantes à da pele original, potencializando seu papel nas investigações sobre permeabilidade de drogas, toxicidade, irritação, eficácia e segurança de compostos e diferenciação de queratinócitos. Uma série de compostos naturais ou sintéticos inibidores de AGEs têm sido descobertos e apresentados recentemente e podem representar inovação terapêutica no tratamento de modificações causadas pela a formação e acúmulo destes AGEs também na pele. Este estudo avaliou o desenvolvimento da pele reconstruída glicada e posteriormente, a avaliação da eficácia e toxicidade de compostos anti-glicação como aminoguanidina e carnosina em modelo de pele reconstruída glicada. Em perspectiva, este estudo contribuiu para o desenvolvimento de uma nova tecnologia in vitro, a pele reconstruída glicada, que auxiliará a compreensão da biologia da interação célula-MEC mimetizando processos fisiopatológicos importantes como o envelhecimento e o DM


The Advanced Glycation End Products (AGEs) of proteins is a common factor to the pathophysiology of a number of disorders related to aging and diseases such as diabetes mellitus (DM). The generation of the AGEs products on skin occurs mainly through non-enzymatic glycation reactions of the dermal extracellular matrix and has been touted as one of the factors responsible for loss of elasticity and disability of skin healing. The skin permeation of compounds is an important limitation for therapeutic/cosmetic efficacy of anti-AGE compounds, which must reach the deepest layers of the skin. Reconstructed skin model containing dermal equivalent modified by in vitro glycation is able to mimic the elderly human skin and represent an efficient model for the study of cells interactions and changes in extracellular matrix induced by aging and diabetes. The 3D reconstructed skin model has metabolic characteristics, permeability and activity similar to the original skin, reinforcing its role in drug permeability of investigations toxicity, irritation, safety and efficacy evaluation of compounds and differentiation of keratinocytes. A number of natural or synthetic AGEs inhibitor compounds have been recently discovered and displayed and can represent therapeutic innovation for the treatment of changes caused by the aging of the skin. In this study we performed the development of reconstructed glycated skin model and evaluated the efficacy and toxicity of anti-glycation compounds such as aminoguanidine and carnosine. In perspective, this study has contributed to the development of a new technology in vitro, and for the understanding cell-extracellular matrix interaction during the aging of skin

ABSTRACT

CONTEXT AND OBJECTIVE: To monitor glycemic control in diabetic patients, regular measurement of glycated hemoglobin (HbA1c) is recommended, but this can be difficult in remote places without access to laboratories. Portable point-of-care testing devices can prove a useful alternative. Our study aimed to assess the performance of one of them: A1CNow+, from Bayer. DESIGN AND SETTING: Cross-sectional accuracy study conducted at a university hospital in Brazil. METHODS: We made three successive measurements of capillary HbA1c using the A1CNow+ in 55 diabetic volunteers, while the same measurement was made on venous blood using the hospital reference method (Vitros 5,1 FS). We used the Bland-Altman graphical method to assess the A1CNow+ in relation to the Vitros 5,1 FS method. We also evaluated clinical usefulness by calculating the sensitivity and specificity of A1CNow+ for detecting patients with HbA1c lower than 7%, which is the usual limit for good glycemic control. RESULTS: The coefficient of variation between repeat testing for the A1CNow+ was 3.6%. The mean difference between A1CNow+ and Vitros 5,1 FS was +0.67% (95% confidence interval, CI: +0.52 to +0.81). The agreement limits of our Bland-Altman graph were -0.45 (95% CI: -0.71 to -0.19) and +1.82 (95% CI: +1.52 to +2.05). The sensitivity and specificity in relation to the 7% limit were respectively 100% and 67.7%. CONCLUSIONS: Although the A1CNow+ had good sensitivity, its accuracy was insufficient for use as a replacement for laboratory measurements of HbA1c, for glycemic control monitoring in diabetic patients.


CONTEXTO E OBJETIVO: Para monitorar o controle glicêmico dos diabéticos, é recomendado medir regularmente a hemoglobina glicada (HbA1c). Isso pode ser difícil em locais distantes sem acesso a laboratórios. Uma alternativa é usar aparelhos portáteis à beira do leito do paciente. Nosso estudo visou avaliar o desempenho de um deles: A1CNow+, da Bayer. TIPO DE ESTUDO E LOCAL: Estudo transversal de acurácia realizado em hospital universitário no Brasil. MÉTODOS: Medimos, com o A1CNow+, três vezes seguidas, a HbA1c capilar de 55 diabéticos voluntários, enquanto a mesma medida era feita em sangue venoso pelo método de referência do hospital (Vitros 5,1 FS). Usamos a análise gráfica de Bland-Altman para avaliar o A1CNow+ em relação ao Vitros 5,1 FS. Verificamos a utilidade clínica através do cálculo da sensibilidade e da especificidade do A1CNow+ para detectar pacientes com HbA1c abaixo de 7%, limite usual indicando glicemia controlada. RESULTADOS: O coeficiente de variação entre testes repetidos do A1CNow+ foi de 3,6%. A diferença média entre o A1CNow+ e o Vitros 5,1 FS foi de +0,67% (95% intervalo de confiança, IC: +0,52 para +0,81). Os limites de concordância do gráfico de Bland-Altman foram -0,45 (95% IC: -0,71 para -0,19) and +1,82 (95% IC: +1,52 para +2,05). A sensibilidade e a especificidade em relação ao limite de 7% foram 100% e 67,7%, respectivamente. CONCLUSÃO: Apesar da boa sensibilidade, o A1CNow+ não tem acurácia suficiente para ser utilizado no monitoramento do controle glicêmico de pacientes diabéticos em substituição das medidas da HbA1c em laboratório.

ABSTRACT

En ninos y adolescentes con diabetes tipo 1 (DT1) puede aparecer precozmente un estado de inflamacion subclinica. El objetivo del trabajo fue determinar los niveles plasmaticos de moleculas proinflamatorias en una poblacion infanto-juvenil con DT1, sin evidencias clinicas de complicaciones vasculares y correlacionar estos parametros entre si y con el grado de control glucemico y tiempo de evolucion de la enfermedad. Se estudiaron 42 pacientes con DT1 (21M/21F), de 10 a 13 anos, que se compararon con un grupo control. Se evaluaron: recuento de leucocitos, formas solubles de E-selectina (sE-S) y molecula de adhesion celular vascular 1 (VCAM-1), mieloperoxidasa (MPO), TNF-á, Fibrinogeno (Fg) y uPCR. Los datos se expresaron como mediana y rango intercuartil. Los diabeticos presentaron niveles aumentados de: sE-S [108 (69-150) vs. 68 (52-86) ng/mL, p=0,003], VCAM-1 [785 (732-835) vs 712 (658-758) ng/mL, p=0,04], uPCR [1,00 (0,67-1,70) vs. 0,20 (0,18-0,87) mg/L, p=0,01]. No se observaron diferencias en las moleculas estudiadas segun el grado de control glucemico y tiempo de evolucion de la enfermedad. La uPCR se correlaciono con glucemia en ayunas, HbA1c, sE-S y VCAM1. Los niveles elevados de uPCR, sE-S y VCAM-1 sugieren un estado proinflamatorio asociado a activacion endotelial en ninos con DT1, potenciando el riesgo de enfermedad vascular.


In children and adolescents with type 1 diabetes (T1D), clinical manifestations of vascular complications are uncommon; however, endothelial disturbance and a pro-inflammatory state can emerge early. The objectives of this work were: I) to determine plasma levels of proinflammatory molecules in a T1D pediatric population with no clinical evidence of vascular complications; II) to correlate these parameters with each other, and with glycemic control degree and disease duration. Forty-two patients with T1D (21 M/21W), aged 10 and 13 years and an evolution time not more than 6 years were compared with a control group. The biochemical parameters evaluated were: WBC, sE-S and VCAM-1, MPO, TNF-á, hsCRP and plasma Fg. Glycemic control was performed by determining fasting glucose and HbA1c. Data were expressed as the median and interquartile range. Increased levels of sE-S [108 (69-150) vs. 68 (52-86) ng/mL, p=0.003], VCAM-1 [785 (732-835) vs. 712 (658-758) ng/mL, p=0.04], hsCRP [1.00 (0.67-1.70) vs. 0.20 (0.18- 0.87) mg/L, p=0.01] were found in diabetic patients compared with the control group. No differences in the studied molecules were observed when diabetic patients were grouped according to glycemic control degree and evolution of the disease. hsCRP correlated with fasting glucose, HbA1c, sE-S and VCAM-1. High hsCRP, sE-S and VCAM-1 levels suggest a proinflammatory state associated with endothelial activation in children and adolescents with T1D, potentiating the risk of vascular disease.

O objetivo do trabalho foi determinar os níveis plasmáticos de moléculas pró-inflamatórias em uma população infanto-juvenil com DM1 sem evidências clínicas de complicações vasculares e correlacionar estes parâmetros, entre si com o grau de controle glicêmico e tempo de evolução da doença. Foram estudados 42 pacientes com DM1 (21M/21F), de 10 a 13 anos, que foram comparados com um grupo controle. Foram avaliadas a contagem de leucócitos, formas solúveis de E-selectina (sE-S) e molécula de adesão celular vascular 1 (VCAM-1), mieloperoxidase (MPO), TNF-á, fibrinogênio (Fg) e PCRus. Os dados foram expressos como mediana e intervalo interquartil. Os pacientes diabéticos apresentaram níveis aumentados de SE-S [108 (69-150) vs. 68 (52-86) ng/mL, p=0,003], VCAM-1 [785 (732-835) vs. 712 (658-758) ng/mL, p=0,04], PCRus [1,00 (0,67-1,70) vs. 0,20 (0,18-0,87) mg/L, p=0,01]. Não foram observadas diferenças nas moléculas estudadas segundo o grau de controle glicêmico e tempo de evolução da doença. O PCRus foi correlacionado com glicemia em jejum, HbA1c, sES e VCAM1. Os níveis elevados de PCRus, sE-S e VCAM-1 sugerem um estado pró-inflamatório associado com a ativação do endotélio em crianças com DM1, aumentando o risco de doença vascular.

ABSTRACT

ABSTRACT CONTEXT AND OBJECTIVE: To evaluate predictors of changes in lipid parameters consisting of LDL-C (low-density lipoprotein cholesterol), TC (total cholesterol) and non-HDL-C (non-high density lipoprotein cholesterol) among primary care patients. DESIGN AND SETTING: Retrospective study conducted on family medicine patients. METHODS: Demographic features and other clinically relevant information were abstracted from medical records. The primary outcome was the difference in LDL-C level from initial testing to the index test. Secondary outcomes were the changes in TC and non-HDL-C levels between two measurements. RESULTS: Three hundred and eleven participants were included in the final secondary analysis. Multiple linear regression revealed that male patients (β = 4.97, P = 0.040), diabetes (β = 9.75, P = 0.003) and higher LDL-C levels at baseline (β = 0.35, P < 0.001) were positively associated with LDL variance, whereas longer time period (β = -0.15, P = 0.045) and familial hypercholesterolemia history (β = -7.56, P = 0.033) were negatively associated. Male patients (β = 8.45, P = 0.002), DM (β = 9.26, P = 0.011), higher TC levels at baseline (β = 0.35, P < 0.001) and taking statins (β = 7.31, P = 0.023) were positively associated with TC variance, whilst longer time period (β = -0.183, P = 0.031) and familial hypercholesterolemia (β = -10.70, P = 0.008) were negatively associated. CONCLUSION: In the present study, patients who were male, on statin treatment, diagnosed with diabetes and had higher baseline lipid values were more likely associated with better lipid outcomes at future testing.


RESUMO CONTEXTO E OBJETIVO: Avaliar preditores de alterações nos parâmetros lipídicos que consistem em LDL-C (colesterol de lipoproteína de baixa densidade), TC (colesterol total) e não HDL-C (não colesterol de lipoproteína de alta densidade) entre os pacientes de cuidados primários. TIPO DE ESTUDO E LOCAL: Estudo retrospectivo realizado em pacientes de medicina familiar. MÉTODOS: Aspectos demográficos e outras informações clinicamente relevantes foram extraídos dos prontuários médicos. O desfecho primário foi a diferença de nível de LDL-C entre os exames iniciais e o exame índice. Os desfechos secundários foram as mudanças dos níveis de TC e não HDL-C entre as duas medidas. RESULTADOS: Trezentos e onze participantes foram incluídos na análise secundária final. Regressão linear múltipla revelou que os pacientes do sexo masculino (β = 4,97, P = 0,040), diabetes (DM) (β = 9,75, P = 0,003) e níveis de LDL mais elevados no início do estudo (β = 0,35, P < 0,001) foram associados positivamente com variância LDL, enquanto longo período de tempo (β = -0,15, P = 0,045) e história hipercolesterolemia familiar (β = -7,56, P = 0,033) foram associados negativamente. Pacientes do sexo masculino (β = 8,45, P = 0,002), com DM (β = 9,26, P = 0,011), níveis elevados de CT na linha de base (β = 0,35, P < 0,001) e tomar estatinas (β = 7,31, P = 0,023) associaram-se positivamente com a variância TC, enquanto longo período de tempo (β = -0,183, P = 0,031), hipercolesterolemia familiar (β = -10,70, P = 0,008) foram associados negativamente. CONCLUSÕES: No presente estudo, os pacientes que eram do sexo masculino, em tratamento com estatinas, com diagnóstico de DM e que tinham valores lipídicos basais mais elevados foram mais provavelmente associados a melhores resultados de lipídios em testes futuros.
