The effect of physical exercise on blood sugar control in diabetic patients / O efeito do exercício físico no controle do açúcar no sangue em pacientes diabéticos / El efecto del ejercicio físico sobre el control del azúcar en sangre en pacientes diabéticos

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.

Inverted U-Shaped Associations between Glycemic Indices and Serum Uric Acid Levels in the General Chinese Population: Findings from the China Cardiometabolic Disease and Cancer Cohort (4C) Study / 生物医学与环境科学（英文）

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.

Can diabetes mellitus modify the plasma concentrations of rifampicin in patients under treatment for tuberculosis?

Abstract Rifampicin is a key component of treatment for tuberculosis and its efficacy is determined by the blood levels attained after therapeutic doses. However, there is a high variability of rifampicin blood levels that is related to both the patient and the formulation used. To date, the effect of diabetes mellitus on the plasma levels of rifampicin was low exploited, which could be relevant either by the significant increase of the comorbidity worldwide as by the probable influence of diabetes on the rifampicin exposure. The study aims to evaluate whether diabetes mellitus contribute to the variation of the maximum concentration of rifampicin in patients with tuberculosis treated with a daily dose of 10 mg/kg. Rifampicin and glycated hemoglobin were measured by high-performance liquid chromatography, and blood glucose by spectrophotometry. A total of 62 male patients were included in the study, and 26 presented diabetes mellitus. Rifampicin plasma levels in 2-h plasma samples collected at day 61 ranged from 3 µg/mL to 14.2 µg/mL. Drugs levels were similar between diabetic and non-diabetic patients and were not correlated with blood glucose and glycated hemoglobin. Moreover, a high percentage of patients in both groups presented low levels of rifampicin.

Perfil bioquímico de pacientes diabéticos de um laboratório privado da região sul do Brasil / Biochemical profile of diabetic patients in a private laboratory in southern Brazil

O diabetes é uma doença crônica decorrente de hiperglicemia permanente. A hemoglobina glicada (HbA1c) resulta da ligação não enzimática entre a hemoglobina e a glicose. A dosagem da mesma é o principal determinante para avaliação do controle glicêmico em pacientes diabéticos. Este estudo objetivou correlacionar idade, perfil glicêmico e lipídico em uma amostra de prontuários de portadores de Diabetes Melito (DM), em um laboratório privado da região sul do Brasil. Foram analisados 776 prontuários no período entre janeiro a março de 2018, sendo que os prontuários foram obtidos a partir de registros dos meses entre março de 2016 a março de 2018. Analisamos HbA1c, glicose, triglicerídeos, colesterol total, LDL-colesterol e HDL-colesterol. Nossos resultados mostram predominância de mulheres idosas (61%), não havendo variação de idade entre os gêneros, em ambos foi possível observar correlação negativa e significativa entre idade e LDL-C. Não houve clara associação entre HbA1c e perfil lipídico na amostra estudada. Os resultados demonstraram aumento nos níveis de HbA1c e redução no colesterol total e LDL-C nos pacientes acima de 60 anos. Encontramos uma forte correlação positiva entre os parâmetros HbA1c e glicose, em ambos os gêneros. As correlações entre idade e demais variáveis foram fracas, entre ambos.

Diabetes is a chronic disease characterized by the presence of permanent hyperglycemia. Glycated Hemoglobin (HbA1c) is formed through the non-enzymatic binding of hemoglobin and glucose. Its dosage in blood is one of the most relevant factors in the evaluation of the glycemic control. The aim of this study is to correlate age, glycemic and lipid profiles in a sample of 776 patients diagnosed with Diabetes Mellitus (DM), from a laboratory in southern Brazil. A total of 776 medical records were analyzed between January and March 2018, and the records were obtained from the records of the months between March 2016 and March 2018. HbA1c, glucose, triglyceride, total cholesterol, LDL-cholesterol and HDL-cholesterol values were analyzed. Our results show a predominance of elderly women (61%), with no age variation between genders, in both it was possible to observe negative and significant correlation between age and LDL-C. There was no clear association between HbA1c and lipid profile. The results showed increased levels of HbA1c and a reduction in total cholesterol and LDL-C in patients over 60 years. A strong positive correlation was found between HbA1c and glucose parameters in both genders. The correlations between age and other variables were weak between both.

A Study of the Association between Diabetes Mellitus and Chronic Hepatitis B Virus Infection / Un Estudio de la Asociación entre la Diabetes Mellitus y la Infección Crónica por el Virus de la Hepatitis B

ABSTRACT Background: Hepatitis B virus (HBV) infection and diabetes mellitus are major health problems associated with significant morbidity and mortality. The published literature suggests an association of diabetes mellitus with liver disease. However, the role of HBV infection in diabetes aetiology is still controversial. The present study was conducted to explore the veracity of this enigmatic association among Pakistani subjects. Methodology: The blood samples and clinical information were collected from chronic HBV-positive patients Group 1 (n = 120), and their age and gender were matched with those of the healthy control subjects Group 2 (n = 120). Hepatitis B virus-positive patients were also subdivided into two groups; (Group 1a and Group 1b) with and without liver cirrhosis for evaluation of the prevalence of diabetes. Results: The study revealed that there were statistically significant differences in the biochemical parameters in the HBV-positive and control groups. There was no correlation between diabetes and HBV with the prevalence of diabetes mellitus being similar in subjects with and without HBsAg (11.7% in the positive group and 10% in the controls). Since there were a relatively large number (32.5%) of HBV-positive patients with liver cirrhosis, a comparison of biochemical parameters was also carried out to evaluate the extent of the liver damage and its association with diabetes. During the comparison of HBV patients with and without cirrhosis for the prevalence of diabetes, no aetiologic association was found with diabetes. Conclusion: Study revealed that there was no correlation between HBV infection and diaabetes despite the significantly different biochemical parameters in the HBV-infected group and control subjects.

RESUMEN Antecedentes: La infección por el virus de la hepatitis B (VHB) y la diabetes mellitus son problemas de salud importantes asociados con morbilidad y mortalidad significativas. La literatura publicada sugiere una asociación de la diabetes mellitus con las enfermedades hepáticas. Sin embargo, el papel de la infección por VHB en la etiología de diabetes sigue siendo contro-versial. El presente estudio fue conducido con el propósito de explorar la veracidad de esta enigmática asociación entre sujetos paquistaníes. Metodología: Se recogieron muestras de sangre e información clínica de pacientes crónicos VHB positivos Grupo 1 (n = 120), y su edad y género fueron comparados con los de los sujetos sanos del control Grupo 2 (n = 120). Los pacientes positivos al virus de la hepatitis B también se subdividieron en dos grupos, a saber, (Grupo 1a y Grupo 1b) con y sin cirrosis hepática en relación con la prevalencia de la diabetes. Resultados: El estudio reveló que hubo diferencias significativas en estos dos grupos en los parámetros bioquímicos entre el grupo de control y el grupo VHB positivo. En estos dos grupos no hubo correlación entre la diabetes y el VHB. Puesto que hubo un número relativamente grande (32.5%) de pacientes VHB positivos con cirrosis hepática, se realizó también una comparación de los parámetros bioquímicos a fin de comprender el grado del daño hepático y su asociación con la diabetes. Durante la comparación de los pacientes con VHB con y sin cirrosis en relación con la prevalencia de diabetes, no se halló asociación etiológica con la diabetes. Conclusión: Este estudio reveló que no hubo correlación entre la infección por VHB y la diabetes, a pesar de los parámetros bioquímicos significativamente diferentes entre el grupo infectado por el VHB y los sujetos del control.

Correlation analysis between short-term insulin-like growth factor-I and glucose intolerance status after transsphenoidal adenomectomy in acromegalic patients: a large retrospective study from a single center in China

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.

Glycated hemoglobin as a predictor of the length of hospital stay in patients following coronary bypass graft surgery in the saudi population

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.

Platelets volume indexes and cardiovascular risk factors

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.

Effects of diabetes and hypertension on oral mucosa and tgfß1 salivary levels

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.

Effect of Family History of Diabetes on Hemoglobin A1c Levels among Individuals with and without Diabetes: The Dong-gu Study

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.

Glycated albumin: a potential biomarker in diabetes

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.

Eficacia de un programa educativo estructurado en población diabética chilena / Effectiveness of a structured educative program in Chilean diabetic patients

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.

Serum adipocytokine profile and metabolic syndrome in young adult female dermatomyositis patients

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.

Association of the conicity index with diabetes and hypertension in Brazilian women

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.

Correlação das dosagens de frutosamina e de hemoglobina glicosilada com o perfil glicêmico em gestantes com diabetes mellitus / Correlation of the Levels of Fructosamine and Glycated Hemoglobin with the Blood Glucose Profile in Pregnant Women with Diabetes Mellitus

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.
