Enfermedad renal crónica en España: prevalencia y factores relacionados en personas con diabetes mellitus mayores de 64 años / Chronic renal disease in spain: prevalence and related factors in persons with diabetes mellitus older than 64 years

INTRODUCCIÓN: La diabetes mellitus tipo 2 y la enfermedad renal crónica (ERC) son afecciones de elevada prevalencia en personas ≥ 65 años y constituyen un importante problema de salud pública. OBJETIVOS: Conocer la prevalencia de la ERC, sus categorías y su relación con diversos factores demográficos y clínicos, en pacientes ancianos con diabetes mellitus tipo 2 en España. MÉTODOS: Estudio epidemiológico, observacional, transversal, multicéntrico, ámbito nacional. Se incluyeron pacientes con diabetes mellitus tipo 2 conocida, edad ≥ 65 años atendidos en Atención Primaria. Se recogieron variables demográficas, antropométricas y analíticas de los últimos 12 meses, incluyendo el cociente albúmina-creatinina y el filtrado glomerular estimado para evaluar la función renal. RESULTADOS: La prevalencia de ERC fue del 37,2% (IC95%, 34,1-40,3%), de insuficiencia renal del 29,7% (IC95%, 26,8-32,6%) y de elevación de la albuminuria del 20,6% (IC95%, 17,3-23,9%), moderadamente elevada 17,8% (IC95%, 14,7-20,9%), severamente elevada 2,8% (IC95%, 1,4-4,2%). La prevalencia de las categorías de ERC fueron: G1 1,3% (IC95%, 0,6-2%), G2 6,2% (IC95%, 4,6-7,8%), G3a 17,2% (IC95%, 14,8-19,6%), G3b 9,8% (IC95%, 7,9-11,7%), G4 2% (IC95%, 1,1-2,9%) y G5 0,7% (IC95%, 0,2-1,2%). En el análisis multivariante, después de ajustar por el resto de variables, la ERC se asoció a mayor edad OR 5,13, (IC95%, 3,15-8,35), alta comorbilidad OR 3,36 (IC95%, 2,2-5,12) y la presencia de tratamiento antihipertensivo OR 2,43 (IC95%, 1,48-4,02). CONCLUSIONES: La ERC es frecuente en la población diabética ≥ 65 años y se asocia con mayor edad, alta comorbilidad e hipertensión tratada. No se ha encontrado asociación con el género y años de evolución de la diabetes

INTRODUCTION: Type 2 diabetes mellitus and chronic kidney disease (CKD) are conditions which have a high prevalence in individuals ≥ 65 years of age and represent a major public health problem. OBJECTIVES: To determine the prevalence of CKD, its categories and its relationship with various demographic and clinical factors in elderly patients with type 2 diabetes mellitus in Spain. METHODS: Observational, cross-sectional, multicenter, Spanish epidemiological study. Patients with known type 2 diabetes mellitus, age ≥ 65 years of age treated in Primary Care were included. We collected demographic, anthropometric and analytical variables from the previous 12 months, including the albumin-to-creatinine ratio and estimated glomerular filtration rate to evaluate renal function. RESULTS: The prevalence of CKD was 37.2% (95% CI, 34.1-40.3%), renal failure was 29.7% (95% CI, 26.8-32.6%) and increased albuminuria was 20.6% (95% CI, 17.3-23.9%), moderately increased albuminuria was 17.8% (95% CI, 14.7-20.9%) and severely increased albuminuria was 2.8% (95% CI, 1.4-4.2%). In turn, the prevalence of CKD categories were: G1 1.3% (95% CI, 0.6-2%), G2 6.2% (95% CI, 4.6-7.8%), G3a 17.2% (95% CI, 14.8-19.6%), G3b 9.8% (95% CI, 7.9-11.7%), G4 2% (95% CI, 1.1-2.9%) and G5 0.7% (95% CI, 0.2-1.2%). In the multivariate analysis, after adjusting for the remaining variables, CKD was associated with elderly age (OR 5.13, 95% CI, 3.15-8.35), high comorbidity (OR 3.36. 95% CI, 2.2-5.12) and presence of antihypertensive treatment (OR 2.43. 95% CI, 1.48-4.02). CONCLUSIONS: CKD is frequent in the diabetic population ≥ 65 years of age and is associated with elderly age, high comorbidity and with treated hypertension. No relationship has been found with gender and time in years since onset of diabetes
