Acute-to-chronic glycemic ratio as an outcome predictor in ischemic stroke in patients with and without diabetes mellitus.

OBJECTIVE: Elevated plasma glucose levels are common in patients suffering acute ischemic stroke (AIS), and acute hyperglycemia has been defined as an independent determinant of adverse outcomes. The impact of acute-to-chronic glycemic ratio (ACR) has been analyzed in other diseases, but its impact on AIS prognosis remains unclear. The main aim of this study was to assess whether the ACR was associated with a 3-month poor prognosis in patients with AIS. RESEARCH, DESIGN AND METHODS: Retrospective analysis of patients admitted for AIS in Hospital del Mar, Barcelona. To estimate the chronic glucose levels (CGL) we used the formula eCGL= [28.7xHbA1c (%)]-46.7. The ACR (glycemic at admission / eCGL) was calculated for all subjects. Tertile 1 was defined as: 0.28-0.92, tertile 2: 0.92-1.13 and tertile 3: > 1.13. Poor prognosis at 3 months after stroke was defined as mRS score 3-6. RESULTS: 2.774 subjects with AIS diagnosis were included. Age, presence of diabetes, previous disability (mRS), initial severity (NIHSS) and revascularization therapy were associated with poor prognosis (p values < 0.05). For each 0.1 increase in ACR, there was a 7% increase in the risk of presenting a poor outcome. The 3rd ACR tertile was independently associated with a poor prognosis and mortality. In the ROC curves, adding the ACR variable to the classical clinical model did not increase the prediction of AIS prognosis (0.786 vs. 0.781). CONCLUSIONS: ACR was positively associated with a poor prognosis and mortality at 3-months follow-up after AIS. Subjects included in the 3rd ACR tertile presented a higher risk of poor prognosis and mortality. Baseline glucose or ACR did not add predictive value in comparison to only using classical clinical variables.

Síndromes pluriglandulares autoinmunes / Autoinmune polyendocrinopathy

Los síndromes pluriglandulares autoinmunes (SPA) afectan a múltiples glándulas endocrinas y asocian otras enfermedades autoinmunes. El SPA tipo 1 se presenta con hipoparatiroidismo, candidiasis mucocutánea y enfermedad de Addison, se debe a una mutación en el gen AutoImmune Regulator (AIRE). El diagnóstico es clínico además de la secuenciación del gen AIRE. El SPA tipo 2 se presenta con enfermedad de Addison, diabetes mellitus tipo1 o enfermedad tiroidea autoinmune, se han implicado múltiples genes, entre ellos los del complejo mayor de histocompatibilidad tipo 2. El SPA tipo 3 se caracteriza por la presencia de enfermedad tiroidea autoinmune y otra enfermedad autoinmune, excluyendo la enfermedad de Addison y el hipoparatiroidismo, se han implicado cuatro genes que pueden conferir susceptibilidad. El diagnóstico del SPA tipo 2 y tipo 3 es clínico, aunque la determinación de autoanticuerpos puede ser útil para la evaluación del riesgo de presentar la enfermedad y para confirmar la enfermedad autoinmune en algunos casos.

Pluriglandular autoimmune syndrome (APS) can affect multiple endocrine glands and is associated with other autoimmune diseases. APS type 1 presents with hypoparathyroidism, mucocutaneous candidiasis and Addison's disease. It is caused by AutoImmune Regulator (AIRE) gene mutation. The diagnosis includes clinical manifestations in addition to AIRE gene sequencing. SPA type 2 presents with Addison's disease, type 1 diabetes, or autoimmune thyroid disease. Multiple genes have been implicated, including those of the class II major histocompatibility complex. SPA type 3 is characterized by autoimmune thyroid disease and other autoimmune disease, excluding Addison's disease and hypoparathyroidism, 4 genes have been implicated and confer susceptibility. The diagnosis of APS type 2 and type 3 includes clinical manifestations, nevertheless, the determination of autoantibodies can be useful to predict the risk of disease manifestation and to confirm the autoimmune disease in some cases.

Déficit de testosterona, síndrome metabólico y diabetes mellitus / Testosterone deficiency, metabolic syndrome and diabetes mellitus

El déficit de testosterona en la edad adulta se relaciona con depresión, disminución de la libido, energía, hematocrito, masa muscular y de la densidad mineral ósea. En los últimos años, también se ha asociado con diversos componentes del síndrome metabólico, que a su vez se relacionan con un aumento de hasta 5 veces en el riesgo de enfermedad cardiovascular. Así, las concentraciones bajas de testosterona se asocian con una mayor resistencia a la insulina, incremento de la masa grasa, colesterol HDL bajo, triglicéridos elevados e hipertensión arterial. Inversamente, el tratamiento sustitutivo en pacientes con déficit de testosterona y diabetes mellitus tipo 2 y/o síndrome metabólico ha demostrado reducciones en la resistencia a la insulina, colesterol total, LDL y triglicéridos, y una mejoría del control glucémico y los parámetros antropométricos (AU)

Testosterone deficiency in adult age is associated with a decrease in libido, energy, hematocrit, muscle mass and bone mineral density, as well as with depression. More recently, testosterone deficiency has also been associated with various components of the metabolic syndrome, which in turn is associated with a five-fold increase in the risk of cardiovascular disease. Low testosterone levels are associated with increased insulin resistance, increase in fat mass, low HDL cholesterol, higher triglyceride levels and hypertension. Testosterone replacement therapy in patients with testosterone deficiency and type 2 diabetes mellitus and/or metabolic syndrome has shown reductions in insulin resistance, total cholesterol, LDL cholesterol and triglycerides and improvement in glycemic control and anthropometric parameters (AU)

Objectives To evaluate the efficiency of a unit for detection of chronic complications of diabetes, and to analyze the incidence and prevalence of complications in a sample of patients from our area of interest and concern

Tratamiento de la diabetes mellitus durante el Ramadán / Treatment of diabetes mellitus during Ramadan

En el tratamiento de las personas con diabetes es fundamental adaptar los esquemas terapéuticos a las características de cada paciente, como la edad, las enfermedades asociadas y las complicaciones de la enfermedad. Esta individualización del tratamiento debe contemplar también los estilos de vida y condicionantes socioculturales y religiosos, como la celebración del Ramadán. Las personas diabéticas de religión musulmana, aunque en teoría están exentas del Ramadán, en la práctica frecuentemente desean cumplir el ayuno. En consecuencia, es necesario un correcto abordaje del paciente durante este período. En la siguiente revisión se exponen la prevalencia de la diabetes en las diferentes etnias y las posibles complicaciones de la diabetes relacionadas con la fisiopatología del ayuno, así como los estudios realizados para el manejo adecuado del paciente con diabetes tipo 1 y tipo 2 durante el Ramadán. Es necesario adaptar la pauta terapéutica, tanto para los pacientes tratados con dieta o fármacos orales como para los tratados con insulina. Es también importante la implicación de los profesionales sanitarios en el consejo, orientación y adaptación del régimen terapéutico de las personas musulmanas con diabetes

In the treatment of patients with diabetes mellitus it is fundamental that the therapeutic schemes are adapted to each's patient characteristics such as age, associated diseases and diabetes complications. This therapeutic individualization must also include lifestyles and socio-cultural and religious factors as the celebration of Ramadan. Although Muslin diabetics are theoretically free from Ramadan, they commonly wish to fast in practice. It is therefore needed a right approach of the patient during this period. In this Review, we analyze the prevalence of diabetes among different ethnicities, the possible complications of the disease in relation to fasting's pathophysiology, and the studies performed to rightly manage type 1 and 2 diabetic patients during Ramadan. It is necessary to adapt the therapeutic scheme both for patients treated with dietetic measures or oral drugs and for patients receiving insulin. It is also important the involvement of health professionals in the advice, orientation and adaptation of the therapeutic regimen of Muslin people with diabetes
