Lixisenatida en pacientes con diabetes tipo 2 y obesidad: más allá del control glucémico / Lixisenatide in patients with type 2 diabetes and obesity: Beyond glycaemic control

OBJETIVO: Evaluar la tolerancia a lixisenatida y sus efectos sobre el peso y el control metabólico de pacientes con diabetes tipo 2 y obesidad. DISEÑO: Estudio prospectivo. Emplazamiento: Consultas de atención especializada de Endocrinología y Nutrición en Almería, Granada y Málaga. PARTICIPANTES: Pacientes con diabetes tipo 2 y obesidad. INTERVENCIONES: Respuesta y tolerancia al tratamiento con lixisenatida. Mediciones principales: Se analizaron datos clínicos y analíticos con medidas de cambio intrasujeto antes-después del tratamiento. RESULTADOS: Evaluamos 104 pacientes (51% mujeres) con diabetes tipo 2 y obesidad (Almería 18,3%; Granada 40,4%; Málaga 41,3%). Edad media 58,4±10,5 años y duración media de diabetes 11,2±6,7 años. El tiempo medio desde la visita basal a la revisión tras inicio de tratamiento con lixisenatida fue de 3,8±1,6 meses. Encontramos mejoría significativa del peso (p < 0,001), índice de masa corporal (p < 0,001), circunferencia de cintura (p = 0,002), presión arterial sistólica (p < 0,001) y diastólica (p = 0,001), glucemia en ayunas (p < 0,001), HbA1c (p = 0,022), colesterol total (p < 0,001), colesterol LDL (p = 0,046) y triglicéridos (p = 0,020). No se observó alteración de cifras de amilasa en relación con el tratamiento con lixisenatida, y el 7,9% no lo toleraron. CONCLUSIONES: Lixisenatida consigue: 1) mejoría significativa de parámetros antropométricos y control glucémico (glucemia basal y HbA1c); 2) descenso significativo de la presión arterial y del perfil lipídico, y 3) seguridad y buena tolerancia en la mayoría de los pacientes. Además, encontramos una significativa intensificación del tratamiento antihipertensivo e hipolipemiante

AIM: To evaluate tolerance to lixisenatide and its effects on weight and metabolic control in type 2 diabetes and obese patients. DESIGN: Prospective study. SETTING: Endocrinology clinics in Almeria, Granada and Malaga. PARTICIPANTS: Patients with type 2 diabetes and obesity. INTERVENTIONS: Response and tolerance to lixisenatide treatment. MAIN MEASUREMENTS: Clinical and analytical data of the subjects were evaluated at baseline and after treatment. RESULTS: The study included 104 patients (51% women) with type 2 diabetes and obesity (Almeria 18.3%; Granada 40.4%; Malaga 41.3%). The mean age was 58.4±10.5 years, and the mean duration of diabetes was 11.2±6.7 years. The patients were re-evaluated at 3.8±1.6 months after treatment with lixisenatide. Significant improvements were found in weight (P<.001), body mass index (P<.001), waist circumference (P=.002), systolic blood pressure (P<.001), diastolic blood pressure (P=.001), fasting glucose (P<.001), HbA1c (P=.022), Total cholesterol (P<.001), LDL-cholesterol (P=.046), triglycerides (P=.020), hypertension drugs (P<.001), and lipids drugs (P<.001). No changes were observed in levels of amylase related to lixisenatide treatment, and 7.9% of patients did not tolerate it. CONCLUSIONS: Lixisenatide achieved significant improvements in anthropometric parameters, glycaemic control (fasting glucose and HbA1c), blood pressure and lipids. It was safe and well tolerated in most patients. In addition, there was a significant increase in the use of antihypertensive and lipid-lowering therapy

Reduction of false-negative papillary thyroid carcinomas by the routine analysis of BRAF(T1799A) mutation on fine-needle aspiration biopsy specimens: a prospective study of 814 thyroid FNAB patients.

OBJECTIVES: To evaluate prospectively the usefulness of the routine determination of BRAF(T1799A) mutation on thyroid fine-needle aspiration biopsy (FNAB) to detect cytopathology false negative papillary thyroid carcinomas (PTC) and, therefore, as a tool to improve the sensitivity of the preoperative cytopathological diagnosis of PTC in thyroid nodules. BACKGROUND: FNAB is the most reliable diagnostic test to discriminate between malignant and benign thyroid nodules, but nondiagnostic results remain a clinical management dilemma. BRAF(T1799A) mutation is the most prevalent genetic alteration in thyroid cancers and is specific for PTC, characteristics that make it the most potentially helpful genetic tool to improve the diagnostic accuracy of FNAB. METHODS: An exhaustive recruitment of all patients subjected to thyroid FNAB in our institution during 4 years was performed. BRAF(T1799A) mutation was determined on thyroid FNAB specimens by PCR and restriction fragment length polymorphism, plus direct sequencing in positive samples. RESULTS: BRAF(T1799A) mutation on FNAB detected 47.2% (17/36) of PTC cases. It confirmed preoperatively 45.5% (5/11) of the PTC cases in the indeterminate category and decreased the rate of cytopathology false-negatives in 33.3% (6/18), improving the combined (BRAF(T1799A) mutation + cytopathological analysis) sensitivity of the detection of PTC on FNAB in 16.7%. CONCLUSIONS: BRAF(T1799A) mutation improves the diagnosis of PTC on FNAB, mainly because of the detection of cytopathology false-negatives, and it can be helpful in the routine analysis of thyroid nodules, especially in clinical settings with moderate sensitivity to detect PTC on FNAB.
