Screening of Fabry Disease in Patients with Chest Pain Without Obstructive Coronary Artery Disease.

Identification of Anderson-Fabry disease (AFD) in cardiac patients has been restricted so far to patients with left ventricular hypertrophy. Coronary microvascular dysfunction has been described in AFD with and without cardiac hypertrophy and may represent the only manifestation in AFD patients, offering a possible earlier diagnosis. We studied the prevalence of AFD in 663 patients with chest pain with normal or non-obstructive coronary arteries. The overall prevalence of AFD in this cohort was only 0.15% (1/663). AFD is not a frequent cause of chest pain without obstructive coronary artery disease and screening efforts should not be conducted in this patient population.

Clinical guide for the diagnosis and follow-up of myotonic dystrophy type 1, MD1 or Steinert's disease. / Guía clínica para el diagnóstico y seguimiento de la distrofia miotónica tipo 1, DM1 o enfermedad de Steinert.

BACKGROUND AND OBJECTIVES: Steinert's disease or myotonic dystrophy type 1 (MD1), (OMIM 160900), is the most prevalent myopathy in adults. It is a multisystemic disorder with dysfunction of virtually all organs and tissues and a great phenotypical variability, which implies that it has to be addressed by different specialities with experience in the disease. The knowledge of the disease and its management has changed dramatically in recent years. This guide tries to establish recommendations for the diagnosis, prognosis, follow-up and treatment of the complications of MD1. MATERIAL AND METHODS: Consensus guide developed through a multidisciplinary approach with a systematic literature review. Neurologists, pulmonologists, cardiologists, endocrinologists, neuropaediatricians and geneticists have participated in the guide. RECOMMENDATIONS: The genetic diagnosis should quantify the number of CTG repetitions. MD1 patients need cardiac and respiratory lifetime follow-up. Before any surgery under general anaesthesia, a respiratory evaluation must be done. Dysphagia must be screened periodically. Genetic counselling must be offered to patients and relatives. CONCLUSION: MD1 is a multisystemic disease that requires specialised multidisciplinary follow-up.

Antecedentes y objetivos: La enfermedad de Steinert o distrofia miotónica tipo 1 (DM1), (OMIM 160900) es la miopatía más prevalente en el adulto. Es una enfermedad multisistémica con alteración de prácticamente todos los órganos y tejidos y una variabilidad fenotípica muy amplia, lo que implica que deba ser atendida por diferentes especialistas que dominen las alteraciones más importantes. En los últimos años se ha avanzado de manera exponencial en el conocimiento de la enfermedad y en su manejo. El objetivo de la guía es establecer recomendaciones para el diagnóstico, el pronóstico, el seguimiento y el tratamiento de las diferentes alteraciones de la DM1. Material y métodos: Esta guía de consenso se ha realizado de manera multidisciplinar. Se ha contado con neurólogos, neumólogos, cardiólogos, endocrinólogos, neuropediatras y genetistas que han realizado una revisión sistemática de la literatura. Recomendaciones: Se recomienda realizar un diagnóstico genético con cuantificación precisa de tripletes CTG. Los pacientes con DM1 deben seguir control cardiológico y neumológico de por vida. Antes de cualquier cirugía con anestesia general debe realizarse una evaluación respiratoria. Debe monitorizarse la presencia de síntomas de disfagia periódicamente. Debe ofrecerse consejo genético a los pacientes con DM1 y a sus familiares. Conclusión: La DM1 es una enfermedad multisistémica que requiere un seguimiento en unidades especializadas multidisciplinares

Enfermedad cardiovascular y función renal. Mecanismos patogénicos / Cardiovascular disease and renal function. Pathogenetic mechanisms

Los pacientes con insuficiencia renal crónica tienen más probabilidad de morir por causa cardiovascular que de progresar a insuficiencia renal terminal. La excreción urinaria de albúmina es un marcador de riesgo tanto de enfermedad renal como de enfermedad cardiovascular en diabéticos y no diabéticos. En la insuficiencia renal crónica, la hipertensión, la dislipemia y la diabetes mellitus son los principales factores de riesgo de disfunción endotelial, inflamación, estrés oxidativo y arteriosclerosis acelerada. La inhibición del sistema renina-angiotensina enlentece la progresión de la enfermedad renal en la diabetes mellitus tipos 1 y 2 y en los no diabéticos con nefropatía. El grado de reducción de albuminuria se relaciona con el riesgo cardiovascular en la diabetes mellitus tipo 2 y la nefropatía. La excreción urinaria de albúmina debe ser utilizada como objetivo terapéutico similar a la presión arterial para reducir las complicaciones renales y cardiovasculares en pacientes con nefropatía (AU)

Patients with chronic kidney failure are more likely to die of cardiovascular disease than to develop end-stage kidney failure. Urinary albumin excretion is a risk marker for both renal and cardiovascular disease in diabetics and nondiabetics. In patients with chronic kidney failure, hypertension, dyslipidemia and diabetes are the main risk factors for the development of endothelial dysfunction, inflammation, oxidative stress and accelerated atherosclerosis. Inhibition of the renin-angiotensin system slows the progression of renal disease in patients with type-1 or type-2 diabetes as well as in nondiabetic patients with nephropathy. In those with type-2 diabetes or nephropathy, there is an association between the degree of albuminuria reduction and cardiovascular risk. The level of urinary albumin excretion should be used as a therapeutic target, like blood pressure, for reducing renal and cardiovascular complications in patients with nephropathy (AU)
