Concordancia entre las ecuaciones "Chronic Kidney Disease Epidemiological Collaboration" y "Modification of Diet in Renal Disease" con la "Berlin Initiative Study" para estimar la función renal en las personas mayores / Concordance between the equations "Chronic Kidney Disease Epidemiological Collaboration" and "Modification of Diet in Renal Disease" with the "Berlin Initiative Study" to estimate renal function in the elderly

OBJETIVO: El filtrado glomerular estimado (FGe) se determina de forma cotidiana mediante fórmulas basadas en creatinina, pero su fiabilidad en personas mayores es limitada. El objetivo fue analizar la concordancia entre la ecuación BIS1, específica del anciano, y las habituales CKD-EPI y MDRD-IDMS, en una amplia población mayor de 70 años. MATERIAL Y MÉTODOS: Estudio transversal retrospectivo. Se calculó FGe por BIS1, CKD-EPI y MDRD-IDMS a partir de datos de sexo, edad y creatinina en 85.089 personas (58,5% mujeres, mediana edad 78 años [RIC 73-83]). Se realizan: test de Wilcoxon, análisis gráfico de Bland-Altman, estudio de la concordancia con el coeficiente de correlación intraclase y tablas comparativas para la clasificación de ERC. RESULTADOS: Las medianas de FGe fueron por BIS1 58mL/min/1,73m2 (RIC 48-70), por CKD-EPI 68mL/min/1,73m2 (RIC 53-84) y por MDRD-IDMS 68mL/min/1,73m2 (RIC 53-82). Se encontró una aceptable concordancia entre BIS1 y CKD-EPI (coeficiente de correlación intraclase =0,87), menor con MDRD-IDMS (coeficiente de correlación intraclase =0,81) y una diferencia media de BIS1 vs. CKD-EPI de 8mL/min/1,73m2 (DE 2,6-18) y de BIS1 vs. MDRD-IDMS de 10mL/min/1,73m2 (DE 6-27), mantenida al estratificar por sexos y grupos de edad. CONCLUSIONES: A pesar del aceptable acuerdo estadístico, el FGe obtenido con la ecuación BIS1 no es intercambiable ni con CKD-EPI ni con MDRD-IDMS. La ecuación BIS1 presenta valores más bajos que CKD-EPI y clasifica en un estadio mayor de ERC a los pacientes, principalmente, cuando FGe está por encima de 30mL/min/1,73m2

OBJECTIVE: Estimated glomerular filtration rate (eGFR) is calculated routinely using creatinine-based formulas, but their reliability in the elderly is limited. The aim of this study was to analyse the concordance between the BIS1 equation which is specific for the elderly, and the usual CKD-EPI and MDRD-IDMS in a large population over 70 years of age. MATERIAL AND METHODS: Retrospective cross-sectional study in which the eGFR was calculated using BIS1, CKD-EPI and MDRD-IDMS equations based on gender, age, and creatinine data of 85,089 subjects (58.5% women, mean age 78 years [IQR 73-83]). The following statistics were carried out: Wilcoxon test, Bland-Altman graphic analysis, study of the concordance using the intraclass correlation coefficient (ICC), and comparison tables for the classification of CKD. RESULTS: The median of the eGFRs using BIS1 was 58mL/min/1.73m2 (IQR 48-70), using CKD-EPI was 68mL/min/1.73m2 (IQR 53-84), and using MDRD it was 68mL/min/1.73m2 (IQR 53-82). The concordance between BIS1 and CKD-EPI (intraclass correlation coefficient =0.87) was found to be acceptable. It was lower with MDRD (intraclass correlation coefficient =0.81). A mean difference of 8mL/min/1.73m2 (SD 2.6-18) was found BIS1 vs. CKD-EPI, and 10mL/min/1.73m2 (SD 6-27) with BIS1 vs. MDRD, which was maintained when stratifying by gender and age groups. CONCLUSIONS: Despite the acceptable statistical agreement, the eGFR obtained with the BIS1 equation is not interchangeable with CKD-EPI or with MDRD-IDMS. The BIS1 equation gives lower values than CKD-EPI, and classifies patients into a higher level of CKD, mainly when the eGFR is above 30mL/min/1.73 m2

Prevalencia de diabetes, utilización de antidiabéticos y grado de control glucémico en la provincia de Cádiz (2014-2016): un estudio de base poblacional / Prevalence of diabetes, use of antidiabetic drugs and degree of glycaemic control in the province of Cadiz (2014-2016): A population-based study

Antecedentes y objetivo: Los objetivos de este estudio fueron evaluar la prevalencia de diabetes mellitus tratada farmacológicamente, analizar los patrones de prescripción de los fármacos antidiabéticos y evaluar el grado de control de la enfermedad en la provincia de Cádiz. Pacientes y métodos: Estudio observacional retrospectivo utilizando las bases de datos del Sistema Público de Salud del Servicio Andaluz de Salud entre los años 2014 a 2016, ambos inclusive. Se consideró persona adulta con diabetes tratada (PADT) aquella persona mayor de 14 años que había consumido al menos un envase de medicación del grupo A10 a lo largo de cada uno de los años correspondientes de estudio. Resultados: La prevalencia de PADT varió entre el 8,65% y el 8,83% de 2014 a 2016, respectivamente. Un 71% de PADT estaban tratadas solo con fármacos no insulínicos, un 11% con insulinas y un 18% con una combinación de ambos. En aproximadamente un tercio de las PADT no se había realizado una determinación de HbA1c a lo largo de cada año. El 69% de las PADT evaluadas tenía en 2016 un adecuado grado de control de acuerdo a los criterios de la RedGDPS (según HbA1c y edad). Conclusión: La prevalencia de diabetes tratada farmacológicamente en la provincia de Cádiz es elevada y parece ir en aumento. Los pacientes presentan un limitado control glucémico, al que puede contribuir de forma predominante el seguimiento inadecuado en casi una tercera parte de los mismos

Background and objective: The aim of the study was to assess the prevalence of diabetes mellitus treated pharmacologically, analyse the prescription patterns of antidiabetic drugs and assess the degree of control over the disease in the province of Cadiz. Patients and methods: An observational retrospective study was conducted with the databases of the public health system of the Andalusian Health Service between 2014 and 2016, inclusive. Adults with treated diabetes (ATD) were considered those older than 14 years who had consumed at least 1 package of medication from the A10 group during the corresponding year covered by the study. Results: The prevalence of ATD varied between 8.65% and 8.83% from 2014 to 2016, respectively. Seventy-one percent of the ATD were treated with only noninsulin drugs, 11% were treated with insulin, and 18% were treated with a combination of both. For approximately one-third of the ATD, an HbA1c reading was not performed during each year. Sixty-nine percent of the assessed ATD in 2016 had an appropriate degree of control according to RedGDPS criteria (based on HbA1c and age). Conclusion: The prevalence of pharmacologically treated diabetes in the province of Cadiz is high and appears to be increasing. The patients presented limited glycaemic control, to which inadequate follow-up in almost a third of the patients could be the major contributor
