Prevalencia de diabetes y descontrol glucémico en México: resultados de la Ensanut 2016 / Prevalence of diabetes and poor glycemic control in Mexico: results from Ensanut 2016

Resumen: Objetivo: Estimar la prevalencia de diabetes (total, diagnosticada y no diagnosticada), de descontrol glucémico en México y sus factores asociados. Material y métodos: Se analizaron 3 700 adultos participantes en la Encuesta Nacional de Salud y Nutrición de 2016. Se estimaron las prevalencias con ponderadores poblacionales y los factores asociados con diabetes total y descontrol glucémico con modelos de regresión de Poisson. Resultados: La prevalencia total de diabetes fue de 13.7% (9.5% diagnosticada, 4.1% no diagnosticada); 68.2% de los diagnosticados presentó descontrol glucémico. Mayor tiempo de diagnóstico, vivir en el centro/sur del país y ser atendido en farmacias se asoció con descontrol glucémico, mientras que ser atendido en los servicios de seguridad social se asoció con mejor control glucémico. Conclusión: Se requieren esfuerzos multisectoriales para fortalecer el tamizaje, diagnóstico oportuno y control de la enfermedad, considerando las diferencias por región y tipo de servicio de salud.

Abstract: Objective: To estimate the prevalence of total, diagnosed and undiagnosed diabetes, and the prevalence of poor glycemic control in Mexico, and its associated factors. Materials and methods: Data from 3 700 adult participants were analysed in the 2016 National Health and Nutrition Survey. Diabetes prevalences were estimated with population weights, and the factors associated with total diabetes and poor glycemic control with Poisson regression models. Results: The total prevalence of diabetes was 13.7% (9.5% diagnosed, 4.1% undiagnosed); 68.2% of people with diagnosed diabetes presented poor glycemic control. Longer disease duration, living in the centre or south of the country and being treated in pharmacies were associated with poor glycemic control. Being treated in a social security system was associated with better glycemic control. Conclusion: Multisectoral efforts are needed to strengthen screening, timely diagnosis and disease control, considering differences by region and type of health service.

Niveles de colesterol no HDL en la población chilena y su asociación con enfermedad cardiovascular y diabetes mellitus: estudio de corte transversal en Encuesta Nacional de Salud 2009-2010 / Non-HDL cholesterol levels in Chilean population and their association with diabetes mellitus and cardiovascular disease

Background Despite aggressive treatment aimed at lowering LDL cholesterol (LDL-C) levels with statins, there is a high residual prevalence of cardiovascular diseases, which may depend on plasma cholesterol transported in other atherogenic lipoproteins. Aims To describe non-HDL cholesterol (non-HDL-C) levels in the Chilean population and their association with diabetes mellitus and cardiovascular disease. To evaluate compliance with non-HDL-C therapeutic goals -according to individual cardiovascular risk- at different levels of triglycerides, in comparison with LDL-C goal achievement. Material and Methods: We analyzed data from 2,792 Chilean subjects aged ≥ 15 years who were included in the 2009-2010 National Health Survey and had valid data for blood lipids, diabetes, and cardiovascular disease. Results Forty five percent of subjects had high non-HDL-C levels. The proportion of diabetic and non-diabetic subjects with high non-HDL-C levels was 81 and 42%, respectively (p < 0.01). A significant discordance was observed in the achievement of therapeutic objectives when LDL-C or non-HDL-C levels were considered, particularly in presence of triglycerides ≥ 150 mg/dl. Namely, 8% of the population showed elevated levels of high non-HDL-C despite adequate LDL-C levels. Conclusions Evaluation and management of elevated non-HDL-C in patients with adequate levels of LDL-C seems worthwhile considering the discordance observed between these blood cholesterol fractions. This strategy may be effective to reduce the residual cardiovascular risk in the Chilean population.

Evaluative Research on Pharmacist-managed Diabetes Care: Focus on Self-Monitoring of Blood Glucose / Investigación Evaluativa sobre Atención a la Diabetes Gestionada por los Farmacéuticos: Enfoque del Automonitoreo de la Glucosa en Sangre

ABSTRACT Objective: Pharmacists have not demonstrated the ability to manage chronic diseases such as Type 2 Diabetes Mellitus, which is an ongoing problem in Trinidad and Tobago. The primary objective was to demonstrate that pharmacists can assist patients to achieve at least a 1% decrease in glycosylated haemoglobin (HbA1c). Methods: A randomized, controlled Pharmacist Evaluative Research Study compared the efficacy of pharmacist-managed care (the intervention), and routine standard management (control) of poorly controlled (abnormal HbA1c, blood pressure, blood glucose and lipid panel) adult diabetic patients. Participants in the intervention group met with the pharmacist at their respective primary care sites on a regular basis for an assessment of adherence to medications, barriers to adherence and education. Control group participants consisted of patients receiving routine care by their primary physician but with no direct intervention by the pharmacist except for the filling of prescriptions. Results: Seventy-five patients were initially recruited. Of these, 48 (20 intervention and 28 control) met the inclusion criteria. It was only possible to analyse the result from 20 patients: 14 (70%) intervention and 6 (21.4%) control because of incomplete collected data. A minimum decrease of at least 1% HbA1c was obtained by 8 (57%) intervention participants compared to 2 (33%) in the control group; while HbA1c remained unchanged for two participants, each in the intervention and control groups (14% and 33%, respectively). Conclusion: We could not conclude any statistical or clinical significance in the paper as the data could only be analysed using descriptive methods. Building a culture of research among pharmacists may promote the use of pharmacists as adjunctive healthcare practitioners to achieve better patient outcomes.

RESUMEN Objetivo: Los farmacéuticos no han demostrado ser capaces de manejar el tratamiento de enfermedades crónicas como el tipo 2 Diabetes mellitus, que es un problema actual en Trinidad y Tobago. El objetivo principal fue demostrar que los farmacéuticos pueden ayudar a los pacientes a lograr al menos una disminución del 1% en hemoglobina (Hba1C). Métodos: Un Estudio de Investigación Evaluativa Farmacéutico controlado aleatorio, comparó la eficacia de la atención gestionada por los farmacéuticos (intervención) y el manejo estándar de rutina (control) de pacientes diabéticos adultos con pobre control (niveles anormales de hemoglobina glicosilada, presión arterial, glucosa en sangre, y perfil lipídico). Los participantes en el grupo de intervención se reunieron de manera regular con el farmacéutico en sus respectivos centros de atención primaria para evaluar el cumplimiento con los medicamentos, así como los obstáculos a la observancia y la educación. Los participantes del grupo de control eran pacientes que recibían atención de rutina de parte de su médico primario, pero sin intervención directa del farmacéutico, excepto para el llenado de prescripciones. Resultados: Setenta-cinco pacientes fueron reclutados inicialmente. De estos, 48 (20 de intervención y 28 de control) cumplían los criterios de inclusión. Debido a que los datos recopilados estaban incompletos, sólo fue posible analizar el resultado de 20 pacientes: 14 (70%) de intervención y 6 (21.4%) de control. Una disminución mínima de al menos 1% de HbA1C fue obtenida por 8 (57%) participantes de intervención en comparación con 2 (33%) en el grupo de control, mientras que el HbA1C permaneció inalterado para 2 participantes, cada uno en los grupos de intervención y control (14% y 33%, respectivamente). Conclusión: Los datos apoyan la hipótesis de que la gestión de los farmacéuticos como profesionales complementarios de la salud, posibilita lograr mejores resultados en los pacientes, a diferencia de lo que ocurre en ausencia de tal gestión.

Diabetic regulation of subjects with type 2 diabetes mellitus is associated with serum vitamin D levels

SUMMARY OBJECTIVE Vitamin D deficiency is not only associated with bone metabolism but also with diabetes mellitus. We aimed to study the possible association between serum vitamin D concentration and HbA1c level in patients with type 2 diabetes mellitus (T2DM) in this retrospective report. METHODS Patients with T2DM were enrolled to the study either in regulated or non-regulated T2DM groups, according to HbA1c levels. An HbA1c level of <8% was considered as relatively controlled and others were considered as poorly controlled T2DM. RESULTS Serum vitamin D levels in poorly controlled T2DM subjects (9.4 (4.9-34) ng/ml) were significantly lower than that of the relatively well regulated T2DM patients (13.5 (3.4-36) ng/ml) (p=0.03). Vitamin D was strongly and inversely correlated with HbA1c levels (r= -0.295, p=0.005). CONCLUSION Whatever the cause or result of the diabetes mellitus, it is clear that lower vitamin D is strongly associated with worse diabetic regulation in T2DM subjects. Randomized controlled larger studies, which research the relation between diabetic regulation and vitamin D status, are needed to claim whether it could be a therapeutic target in future in diabetic subjects.

RESUMO CONTEXTO E OBJETIVO A deficiência de vitamina D não é apenas associada ao metabolismo ósseo, mas também ao diabetes mellitus. Procurou-se estudar a possível associação entre os níveis de concentração do soro de vitamina D e de HbA1c em pacientes com diabetes mellitus tipo 2 neste relatório retrospectivo. MÉTODOS Os pacientes com diabetes mellitus tipo 2 foram inscritos no estudo em regulada ou não regulada de acordo com os grupos de níveis de HbA1c DM2. HbA1c nível de <8% caracterizava DM2 controlada e HbA1c > 8% DM2 descontrolada. RESULTADOS Os níveis de vitamina D no soro em indivíduos com DM2 mal regulados (9,4 (4,9 a 34) ng/ml) foram significativamente menores do que o do bem regulado em doentes DM2 (13,5 (3,4-36) ng/ml) (p = 0,03). A vitamina D foi forte e inversamente correlacionada com os níveis de HbA1c (p = 0,005). CONCLUSÃO Seja qual for a causa ou o resultado do diabetes mellitus, é claro que níveis baixos de vitamina D são fortemente associados com pior regulação em indivíduos diabéticos com DM2. Maiores estudos randomizados e controlados que pesquisam a relação entre o status de vitamina D e a regulação em diabéticos são necessários para molusco se é, no futuro, poderia ser um alvo terapêutico em indivíduos diabéticos.

Efecto del ejercicio sobre la inflamación y ferritina sérica en pacientes con obesidad y diabetes mellitus 2 / Effect of exercise on inflammation and serum ferritin in patients with obesity and type 2 diabetes mellitus

Type 2 Diabetes Mellitus (DM2) is considered a chronic inflammatory and systemic disease of low degree of intensity that promotes other pathologies such as cardiovascular disease, cancer and cognitive impairment. The relationship between inflammatory markers and insulin resistance in obese patients is known. Low-grade inflammation is an independent predictor of chronic diseases and mortality from all causes. Ferritin may be increased in DM2, but it is not clear if its cause is hyperglycemia or chronic inflammation. Objective: To evaluate the impact of a twenty-week program of exercise and diet on the markers of inflammation, metabolic control and the value of ferritin in a sample of obese patients with DM2, assisted in our National Health System. Materials and Methods: Open, controlled and randomized clinical trial in primary care patients. Of 161 patients with DM2 evaluated 35 fulfilled the inclusion criteria. They were divided into two homogeneous groups (control and intervention). Blood was taken from both groups to measure Ferritin along with other inflammatory and metabolic markers, before and after the exercise and diet program. These variables and the changes in serum Ferritin were analyzed. Results: At the beginning of the study Ferritin was elevated in 72.2% and 52.9% of the control and intervention group respectively. In the end, there was a significant difference between the groups, with benefit of the intervention group in the decrease of Interleukin-6, glycosylated hemoglobin, waist and body mass index. There was a non-significant decrease in C-reactive protein and Ferritin. This last one was not related to the other variables. The control group showed no significant decrease of any variable Conclusions: To apply a program of controlled exercise and diet, in the usual treatment of patients with DM2, improves inflammation and glucose homeostasis, discernible by the decrease in inflammatory parameters and by the improvement in the glycemic control. Serum ferritin was not useful to predict the metabolic control of these patients and assess the response to treatment.

Introducción: La diabetes mellitus 2 (DM2) es considerada una enfermedad inflamatoria crónica y sistémica de bajo grado de intensidad que promueve otras patologías. Es conocida la relación entre |inflamación e insulino resistencia en pacientes obesos, siendo un predictor independiente de morbimortalidad por todas las causas. Ferritina puede estar aumentada en la DM2, no es claro si su causa es la hiperglucemia o la inflamación crónica. Objetivo: Evaluar el impacto de un programa de veinte semanas de ejercicio y dieta sobre los marcadores de inflamación, control metabólico y el valor de ferritina en una muestra de pacientes con DM2 obesos. Materiales y Métodos: Ensayo clínico abierto, controlado y randomizado en pacientes del nivel primario de atención. Se evaluaron 35 pacientes con DM2 que se dividieron en dos grupos homogéneos (control e intervención). Se extrajo sangre para medir Ferritina, marcadores inflamatorios y metabólicos, antes y luego del programa de ejercicio y dieta. Analizamos los cambios de esas variables. Resultados: Ferritina estaba elevada en el 72.2% y 52.9% del grupo control e intervención respectivamente. Al final hubo una diferencia significativa entre los grupos, con beneficio del grupo intervención en el descenso de Interleucina-6, hemoglobina glicosilada, cintura e índice de masa corporal. Hubo un descenso no significativo de Ferritina y Proteína C reactiva. Ferritina no presentó relación con las demás variables. En el grupo control no hubo descenso significativo de ninguna variable. Conclusiones: Aplicar un programa de ejercicio controlado y dieta, en el tratamiento de pacientes con DM2, mejora la inflamación y la homeostasis de la glucosa, discernible por el descenso de parámetros inflamatorios y por la mejora en el control glucémico. Ferritina sérica no fue útil para predecir el control metabólico y valorar la respuesta al tratamiento.

Diabetes Gestacional: asociación con grupo ABO / Association of abo blood groups with gestational diabetes mellitus

Background: ABO and Rhesus blood systems are associated with type 2 Diabetes Mellitus (DM2). Gestational Diabetes (GDM) is a model to study DM. Aim: To study the association between GDM and ABO and Rhesus groups. Material and Methods: A retrospective cohort study was performed in 1,078 women who gave birth to a singleton in Talca Regional Hospital, Chile, during 2008. We analyzed personal, obstetric, medical data and ABO and Rh blood groups. Results: GDM was diagnosed in 6.6% of women. Age and body mass index were significantly associated with GDM. There were no differences in Rh blood groups (p = 0.604), while ABO groups were different between GDM and controls. B antigen was present in 3% of GDM women and in 10.8% of controls (p = 0.037), with an odds ratio of 0.25 after adjusting for other associated risk factors (p = 0.06). Conclusions: ABO group is suggested as a possible protector marker for GDM.

Drug-induced Liver Injury Caused by Ipragliflozin Administration with Causality Established by a Positive Lymphocyte Transformation Test (LTT) and the Roussel Uclaf Causality Assessment Method (RUCAM): A Case Report

ABSTRACT A 75-year old male patient had been regularly visiting our hospital for the management of his type 2 diabetes mellitus since he was diagnosed at age 64 years. When he developed hypoglycemic episodes with sulfonylurea, ipragliflozin (50 mg/day) was started to replace the sulfonylurea therapy. However, 49 days after starting ipragliflozin, his AST increased from 13 to 622 U/L, ALT increased from 9 to 266 U/L, ALP increased from 239 to 752 U/L, and γ-GTP increased from 19 to 176 U/L. ZTT was 3.5 U, TTT was 0.4 U, and total bilirubin was 0.7 mg/dL. IgM hepatitis A antibody, hepatitis B antigen, hepatitis C virus antibody, IgM CMV antibody, and IgM EB VCA antibody were negative, whereas a lymphocyte transformation test for ipragliflozin was positive. Abdominal CT scan showed mild fatty liver but no sign of nodular lesions. Following admission to our hospital, he received liver supportive therapy with the discontinuation of ipragliflozin therapy. He was discharged from the hospital 18 days later with AST and ALT levels reduced to 20 U/L and 13 U/L, respectively. Based on the clinical presentation of this patient, it is highly important to monitor liver function along with other possible clinical complications (e.g., dehydration, ketosis, and urinary tract infection) associated with SGLT2 inhibitor therapy.

Bradykinin, insulin, and glycemia responses to exercise performed above and below lactate threshold in individuals with type 2 diabetes

The aim of this study was to analyze the acute responses of bradykinin, insulin, and glycemia to exercise performed above and below lactate threshold (LT) in individuals with type 2 diabetes mellitus (T2D). Eleven participants with a diagnosis of T2D randomly underwent three experimental sessions 72 h apart: 1) 20 min of exercise performed at 120% of LT (120%LT), 2) 20 min of exercise performed at 80% of LT (80%LT), and 3) 20 min of control session. Blood glucose was analyzed before, during, and at 45 min post-exercise. Bradykinin and insulin were analyzed before and at 45 min post-exercise. Both exercise sessions elicited a parallel decrease in glucose level during exercise (P≤0.002), with a greater decrease being observed for 120%LT (P=0.005). Glucose decreased 22.7 mg/dL (95%CI=10.3 to 35, P=0.001) at the 45 min post-exercise recovery period for 80%LT and decreased 31.2 mg/dL (95%CI=18.1 to 44.4, P<0.001) for 120%LT (P=0.004). Insulin decreased at post-exercise for 80%LT (P=0.001) and control (P≤0.035). Bradykinin increased at 45 min post-exercise only for 80%LT (P=0.013), but was unrelated to the decrease in glucose (r=-0.16, P=0.642). In conclusion, exercise performed above and below LT reduced glycemia independently of insulin, but exercise above LT was more effective in individuals with T2D. However, these changes were unrelated to the increase in circulating bradykinin.

Glycemic control and adipokines after periodontal therapy in patients with Type 2 diabetes and chronic periodontitis

Abstract: The mechanism by which chronic periodontitis (CP) affects type 2 diabetes (T2DM) remains unclear. Therefore, the aim of this study is to evaluate the effects of periodontal therapy (PT) on the glycemic control and adipokines of patients with T2DM and CP with the purpose of elucidating the possible mechanisms by which CP influences T2DM. Forty-four patients with T2DM and CP were randomly divided into two groups according to whether they underwent PT. Periodontal status, blood glucose, and the levels of serum tumor necrosis factor α (TNF-α), interleukin-6 (IL-6), adiponectin (APN), and fibroblast growth factor-21 (FGF-21) were measured at baseline and after 3 months. The results revealed that the probing depth (PD) and attachment loss (AL) were significantly improved, the serum levels of TNF-α and IL-6 were significantly decreased, and APN and FGF-21 exhibited substantial increases in the intervention group after 3 months (p < 0.05), whereas no significant changes were observed in the control group. The glycated hemoglobin (HbA1c) levels in both groups decreased significantly after 3 months compared with baseline (p < 0.05), but the intervention group exhibited a significantly greater change (p < 0.05). In conclusion, PT may relieve periodontal inflammation, which causes a reduction of insulin-antagonizing adipokines and an increase in insulin-sensitizing adipokines, thereby eliciting an improvement in glycemic control.

Factors associated with glycemic control in people with diabetes at the Family Health Strategy in Pernambuco / Factores asociados con el control glucémico en personas con diabetes en la Estrategia Salud de la Familia en Pernambuco / Fatores associados ao controle glicêmico em pessoas com diabetes na Estratégia Saúde da Família em Pernambuco

Abstract OBJECTIVE Identifying factors associated with glycemic control in people with type 2 Diabetes Mellitus (DM) registered in the Family Health Strategy (FHS) in Pernambuco, Brazil. METHOD Associations between glycemic control (glycosylated hemoglobin A lower or equal to 7%) presented by people with DM and variables related to sociodemographic conditions, lifestyle, characteristics of diabetes, treatment and follow-up of patients by health services were investigated by multiple regression. RESULTS More than 65% of the participants presented inadequate glycemic control, especially those with lower age, longer illness duration, more annual contacts with FHS and complex therapeutic regimen. People with DM without referrals to specialists presented greater glycemic control. Associations with education level and obesity did not remain significant in the multivariate model. CONCLUSION The evolution of diabetes hinders adequate control, however, attention to younger people with DM and referrals to specialists are factors that can improve glycemic control.

Resumen OBJETIVO Identificar los factores asociados con el control glucémico en personas con Diabetes Mellitus (DM) tipo 2 registradas en la Estrategia Salud de la Familia (ESF) en Pernambuco, Brasil. MÉTODO Fueron investigadas, por regresión múltiple, las asociaciones entre el control glucémico (hemoglobina A glicosilada menor o mayor o igual al 7%) presentado por las personas con DM y variables relacionadas con condiciones sociodemográficas, hábitos de vida, características de la diabetes, de su tratamiento y seguimiento de los pacientes por los servicios sanitarios. RESULTADOS Más del 65% de los participantes presentaron control glucémico inadecuado, especialmente aquellos de menos edad, duración de la enfermedad más larga, más contactos anuales con la ESF y régimen terapéutico complejo. Personas con DM sin derivaciones a especialistas presentaron un mayor descontrol glucémico. Asociaciones con escolaridad y obesidad no permanecieron significativas en el modelo multivariado. CONCLUSIÓN La evolución de la diabetes dificulta el control adecuado. Sin embargo, la atención a las personas con DM más jóvenes y las derivaciones a especialistas son factores susceptibles de mejora del control glucémico.

Resumo OBJETIVO Identificar fatores associados ao controle glicêmico em pessoas com Diabetes Mellitus (DM) tipo 2 cadastradas na Estratégia Saúde da Família (ESF) em Pernambuco, Brasil. MÉTODO Foram investigadas, por regressão múltipla, as associações entre o controle glicêmico (hemoglobina A glicosilada menor ou maior ou igual a 7%) apresentado pelas pessoas com DM e variáveis relacionadas com condições sociodemográficas, hábitos de vida, características do diabetes, de seu tratamento e acompanhamento dos pacientes pelos serviços de saúde. RESULTADOS Mais de 65% dos participantes apresentaram controle glicêmico inadequado, principalmente aqueles com idade menor, duração da doença mais longa, mais contatos anuais com a ESF e regime terapêutico complexo. Pessoas com DM sem encaminhamentos para especialistas apresentaram um maior descontrole glicêmico. Associações com escolaridade e obesidade não permaneceram significativas no modelo multivariado. CONCLUSÃO A evolução do diabetes dificulta o controle adequado, todavia, a atenção às pessoas com DM mais jovens e os encaminhamentos para especialistas são fatores suscetíveis de melhora do controle glicêmico.

Serum uric acid and its association with hypertension, early nephropathy and chronic kidney disease in type 2 diabetic patients / Ácido úrico sérico e sua associação com hipertensão, nefropatia precoce e doença renal crônica em pacientes diabéticos tipo 2

Abstract Introduction: Early detection diabetic nephropathy (DN) is important. Whether serum uric acid (SUA) has a role in the development of DN is not known. Objective: To study the relationship between SUA and hypertension, early nephropathy and progression of chronic kidney disease (CKD) in type 2 diabetes mellitus (T2DM). Methods: The total number of the study was 986 participants, according to presence and duration of diabetes were classified into three groups. Group I; including 250 healthy participants. Group II; including 352 with onset of diabetes < 5 years. Group III; including 384, with the onset of diabetes > 5 years. All participants were submitted to complete clinical examination, anthropometric measurements, laboratory investigations, including glycosylated hemoglobin (HbA1C), as well triglycerides to high-density lipoprotein ratios (TG/HDL-C), SUA, urinary albumin/creatinine ratio (ACR) and estimated glomerular filtration rate (eGFR). Results: SUA, BP, HbA1c, TG/HDL-C ratio, and ACR levels were significantly higher in group III than group I, II and in II than I. eGFR significantly lower in group III than group I, II and in II than I (p < 0.001). Age, BMI, BP, HbA1c, TG/HDL-C, ACR, were positively correlated with SUA, while GFR negatively correlated. SUA at level of > 6.1 mg/dl, > 6.2 mg/dl and > 6.5 mg/dl had a greater sensitivity and specificity for identifying hypertension, early nephropathy and decline eGFR respectively. Conclusion: Even high normal SUA level, was associated with the risk of hypertension, early nephropathy and decline of eGFR. Moreover SUA level may identify the onset of hypertension, early nephropathy and progression of CKD in T2DM.

Resumo Introdução: A detecção precoce da nefropatia diabética (ND) é importante. O ácido úrico sérico (AUS) tem um papel ainda desconhecido no desenvolvimento de ND. Objetivo: Estudar a relação entre AUS e hipertensão, nefropatia precoce e progressão da doença renal crônica (DRC) no diabetes mellitus tipo 2 (DM2). Métodos: O estudo contou com 986 participantes, de acordo com a presença e a duração do diabetes, os pacientes foram classificados em três grupos. O Grupo I incluiu 250 participantes saudáveis. O Grupo II incluiu 352 pacientes com início de diabetes < 5 anos. O Grupo III incluiu 384 pacientes com o aparecimento de diabetes > 5 anos. Todos os participantes foram submetidos a exame clínico completo, medidas antropométricas, exames laboratoriais - incluindo hemoglobina glicosilada (HbA1C), bem como a razão entre triglicérides e lipoproteína de alta densidade (TG/HDL-C), AUS, razão creatinina/albumina (RCA) urinária, e taxa estimada de filtração glomerular (eTFG). Resultados: A razão AUS, PA, HbA1c, TG/HDL-C e RCA foi significativamente maior no grupo III do que no grupo I, II e em II do que I. A eTFG foi significativamente menor no grupo III do que nos grupos I, II e no II do que no I (p < 0,001). Idade, IMC, PA, HbA1c, razão TG/HDL-C, RCA, foram positivamente correlacionados com AUS, enquanto que a TFG esteve negativamente correlacionada. O AUS a níveis > 6,1 mg/dl, > 6,2 mg/dl e > 6,5 mg/dl apresentou maior sensibilidade e especificidade para identificar hipertensão, nefropatia precoce e declínio da eTFG, respectivamente. Conclusão: Mesmo elevados níveis de AUS, foi associado ao risco de hipertensão, nefropatia precoce e declínio da eTFG. Além disso, o nível de AUS pode identificar o início da hipertensão, nefropatia precoce e progressão da DRC em DM2.

The individual contribution and relative importance of self-management and quality of care on glycaemic control in type 2 diabetes / Contribución individual e importancia relativa del auto-cuidado y la calidad de la atención en el control glucémico de la diabetes tipo 2

Abstract: Objective: To evaluate the relative importance of selfmanagement (SM) and quality of care (QoC) inpredicting glycaemic control in patients with type 2 diabetes. Materials and methods: A longitudinal cohort study was conducted in 204 adults diagnosed with type 2 diabetes. Self-management and quality of care were measured at baseline. HbA1c was measured at baseline and at six-month follow-up. Results: None of the measures of self-management were significantly associated with HbA1c.Treatment intensification (TI) (a proxy for quality of care) resulted in lower HbA1c at follow-up. Other variables were associated with HbA1c at follow-up: HbA1c at baseline, age, diabetes duration, and combination of oral glucose-lowering medications. An exploratory analysis showed that patients who did not receive treatment intensification but performed more self-management behaviours had lower HbA1c levels at follow-up. Conclusion: Treatment intensification might be more important for glycaemic control than self-management but the interaction between treatment intensification and self-management needs further research.

Resumen: Objetivo: Evaluar la importancia relativa del autocuidado (AU) y calidad de la atención (CA) para predecir control glucémico en diabetes mellitus tipo 2 (DM2). Material y métodos: Estudio longitudinal en 204 adultos con DM2. AU y CA evaluados en la medición basal. HbA1c evaluada en la medición basal y a los seis meses. Resultados: A los seis meses, ninguna de las mediciones de AU se asoció significativamente con HbA1c. La intensificación en el tratamiento (IT) (proxy de CA) se asoció con disminución de HbA1c. Otras variables asociadas con HbA1c: HbA1c en medición basal, edad, duración de diabetes, y combinación de anti-hiperglucemiantes. En un análisis exploratorio, los participantes que no recibieron IT pero desempeñaron más conductas de AU tuvieron niveles más bajos de HbA1c. Conclusión: IT parece ser más importante para el control glucémico que AU, pero la interacción entre IT y conductas de AU se deben estudiar con más profundidad.

Type 2 Diabetes Mellitus remission eighteen months after Roux-en-Y gastric bypass / Remissão do Diabetes Mellitus Tipo 2 dezoito meses após gastroplastia com derivação em Y-de-Roux

ABSTRACT Objective: to evaluate the effectiveness of Roux-en-Y gastric bypass in improving the glycemic profile of obese patients with type 2 Diabetes Mellitus (DM2) after 18 months of follow-up. Methods: four hundred sixty-eight pacients with DM2 and BMI ≥35 were submitted to Roux-en-Y gastric bypass, from 1998 to 2010. All patients were submitted to glycemic control analysis in the 3rd, 6th, 9th, 12th and 18th postoperative months. We considered: type 2 diabetic patients, the ones with fasting glucose ≥126mg/dl and HbA1C ≥6.5 in two dosages; high risk patients for diabetes, those who presented fasting glucose ≥ 100 to 125 mg/dl and HbA1C between 5.7%-6.4%; and normal patients, those presenting glucose <100mg/dl and HbA1C <5.7%. Such diagnostic criteria were based on the official position of Sociedade Brasileira de Diabetes, published in July, 2011. Results: The remission of DM2 was seen in 410 (87.6%) out of 468 patients 18 months after the surgery, that being a meaningful difference, with p<0.001. Fourty-eight (10.3%) patients sustained criteria for the disease and ten (2.1%) continued at high risk for DM2. Conclusions: Roux-en-Y gastric bypass was effective in the promotion and maintaince of long-term glycemic control. There are evidences showing that the remission of DM2 is not only related to weight loss and that other enteroinsular axis mechanisms must be involved.

RESUMO Objetivo: avaliar a eficácia da gastroplastia com derivação em Y-de-Roux, em pacientes obesos e portadores de Diabetes Mellitus tipo 2 (DM2), na melhoria do perfil glicêmico após 18 meses de seguimento. Métodos: foram submetidos à derivação gástrica em Y-de-Roux 468 pacientes com IMC ≥35 e portadores de DM2, no período de 1998 a 2010. Todos os pacientes tiveram a análise do controle glicêmico realizadas no terceiro, sexto, nono, 12o e 18o meses de pós-operatório. Os critérios diagnósticos de diabetes foram baseados no Posicionamento Oficial da Sociedade Brasileira de Diabetes, publicado em julho de 2011. Resultados: observou-se a remissão do DM2 em 410 pacientes (87,6%) após 18 meses da cirurgia, sendo essa diferença significativa com p-valor <0,001. A doença se manteve inalterada em 48 pacientes (10,3%), e dez pacientes (2,1%) permaneceram com o risco aumentado para DM2. Conclusão: a gastroplastia com derivação em Y-de-Roux foi efetiva na promoção e manutenção do controle glicêmico em longo prazo.

Diabetes education in primary care: a randomized clinical trial / Educação em diabetes na atenção primária: um ensaio clínico randomizado / Educación sobre diabetes en la atención primaria: un ensayo clínico aleatorizado

Abstract: The aim of the study was to evaluate the effect of a structured group education program administered by a primary care nurse in patients with type 2 diabetes mellitus. The sample included 137 patients with type 2 diabetes mellitus, randomized into two groups: intervention (5-week educational course and reinforcements every 4 months for one year) and control (with no structured diabetes mellitus education) with an evaluation of metabolic control, weight, blood pressure, distress scores, and knowledge on diabetes. There were no differences between the two groups in HbA1c at 4, 8, or 12 months when compared to baseline values. An increase in HbA1c was observed in the control group after adjusting for baseline HbA1c and insulin dose (p = 0.044 between groups). Knowledge scores and diabetes-related distress improved after the intervention. A structured educational program administered to type 2 diabetes mellitus patients seen at a primary care unit improved the knowledge and distress associated with the disease. The results also suggest the prevention of an increase in HbA1c.

Resumo: O objetivo deste estudo foi avaliar o efeito de um programa de educação estruturado em grupo, aplicado por enfermeira de cuidados primários a pacientes com diabetes mellitus tipo 2. A amostra contou com 137 pacientes com diabetes mellitus tipo 2, randomizados em dois grupos: intervenção, (curso educativo de cinco semanas e reforços a cada 4 meses, durante um ano) e grupo controle (sem educação estruturada) com avaliação do controle metabólico, peso, pressão arterial, escores de estresse e conhecimento relacionados ao diabetes. Não houve diferenças entre os grupos na HbA1c em 4, 8 ou 12 meses, quando comparado aos valores basais. Foi observado um incremento na HbA1c no grupo controle após ajustes para HbA1c no basal e dose de insulina (p = 0,044 entre grupos). Os escores de conhecimento e estresse relacionados ao diabetes melhoraram após a intervenção. Um programa educacional estruturado ministrado à pacientes com diabetes mellitus tipo 2 atendidos em atenção primaria melhorou o conhecimento e estresse associados à doença. Além disso, nossos resultados sugerem uma prevenção de elevação da HbA1c.

Resumen: El objetivo de este estudio fue evaluar el efecto de un programa de educación estructurada en grupo, aplicado por la enfermera de atención primaria para pacientes con diabetes mellitus tipo 2. La muestra incluyó a 137 pacientes con diabetes mellitus tipo 2, aleatorizados en dos grupos: intervención (curso de formación de 5 semanas, com refuerzos cada 4 meses durante un año) y el grupo de control (sin educación estructurada) para evaluar el control metabólico, peso, presión arterial, niveles de estrés y conocimientos relacionados con la diabetes. No hubo diferencias entre los grupos en HbA1c en 4, 8 ó 12 meses en comparación con los valores basales. Se observó un aumento de HbA1c en el grupo de control después del ajuste de HbA1c en la línea de base y a la dosis de la insulina (p = 0,044 entre grupos). Las puntuaciones de los conocimientos y del estrés relacionadas con la diabetes mejoraron después de la intervención. Un programa educativo estructurado ofrecido a los pacientes con diabetes mellitus tipo 2 tratados en la atención primaria mejoró el conocimiento y el estrés asociado con la enfermedad. Por otra parte, nuestros resultados sugieren una prevención elevada de la HbA1c.

Medium-term glycemic control in diabetics before coronary bypass surgery

The aim of this study was to determine the association between preoperative medium-term (60-90 days) glycemic control, as reflected by glycosylated hemoglobin levels (HbA1c), and the incidence of major complications (mediastinitis, perioperative infarction, heart failure, stroke and kidney failure dialysis) and mortality in diabetic patients undergoing elective coronary artery by-pass graft surgery (CABG). This study suggests that aggressive glycemic control three months before surgery, achieving HbA1c ≤ 7% improvement results with less postoperative morbidity and mortality.

El propósito de este estudio fue determinar la asociación entre el control glucémico a mediano plazo, 2-3 meses previos a la cirugía cardiaca, evaluado mediante el dosaje de hemoglobina glicosilada (HbA1c), y la incidencia de muerte y complicaciones mayores (mediastinitis, infarto perioperatorio, insuficiencia cardíaca, accidente cerebrovascular e insuficiencia renal dialítica) en pacientes diabéticos tipo 2. Este estudio sugiere que el control glucémico 3 meses antes de la cirugía en pacientes con diabetes mellitus tipo 2, logrando HbA1c ≤ 7%, mejora los resultados en el posoperatorio observándose menor morbilidad y mortalidad.
