El incremento de la excreción de albúmina urinaria es predictivo de insuficiencia renal terminal y de eventos vasculares. Por ello es prioritaria su detección para realizar una actuación agresiva y simultánea sobre todos los factores de riesgo vascular.

Resumen
La nefropatía diabética es la afección renal secundaria a la hiperglucemia crónica. Aunque la excreción de albúmina urinaria es la clave del diagnóstico de la nefropatía diabética, hasta 30% de pacientes con diabetes tipo 2 con normoalbuminuria pueden tener una tasa de filtración glomerular < 60 ml/min. Por ello es conveniente determinar simultáneamente ambas para la detección sistemática de nefropatía. El incremento de excreción de albúmina urinaria predice la progresión a nefropatía terminal e incrementa el riesgo vascular del paciente diabético. Recientemente describimos en nuestra población que tanto el incremento de la excreción de albúmina urinaria como la disfunción renal leve son capaces de predecir la aparición de eventos cardiovasculares. Los factores de riesgo más consistentes para la aparición y progresión de la nefropatía son la hiperglucemia (sobre todo en fases iniciales) y la hipertensión (principalmente en fases avanzadas). Hay nivel de evidencia A para recomendar en pacientes con nefropatía: optimización del control de la glucosa (HbA1c < 7%), optimización del control de la presión arterial (< 130/80 mm Hg) y uso de fármacos inhibidores del sistema renina-angiotensina. Debido a su elevado riesgo vascular, podría ser conveniente además lograr objetivos de colesterol asociado a lipoproteínas de baja densidad < 70 mg/dl. En cualquier caso lo fundamental es una actuación simultánea y agresiva sobre todos los factores de riesgo vascular.

Abstract
Diabetic nephropathy is the kidney disease due to chronic hyperglycaemia. Although elevation of urinary albumin excretion rate (UAER) is the earlier manifestation of diabetic nephropathy, it has been described that 30% of normoalbuminuric type 2 diabetic patients have a glomerular filtration rate (GFR) of less than 60 ml/minute. So, it is recommended to determine simultaneously UAER and GFR in the screening for diabetic nephropathy. The elevation of UAER is a predictor of chronic renal failure and a predictor of cardiovascular disease. We have recently described that both, microalbuminuria and mild renal failure, are involved in the incidence of cardiovascular events. The main risk factors for the development and progression of diabetic nephropathy are hyperglycaemia and hypertension. There is Level A of evidence in diabetic nephropathy to recommend a HbA1c level of less than 7%, a blood pressure level of less than 130/80 and the utilization of ACE inhibitors or angiotensin blockers. Due to the very high vascular risk of these patients, it is also necessary to obtain a LDL cholesterol level of less than 70 mg/dl. In conclusion, it is necessary to act simultaneously and aggressively on all cardiovascular risk factors.
