E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Compare the progression of CKD defined as the number of patients increasing by 50 % the baseline serum creatinine value or reach CKD stage 5 , dialysis or transplantation , or death between the group receiving 25 OH vitamin D and the group without active treatment |
Comparar la progresión de ERC definida como número de paciente que incrementan en 50 % la cifra de creatinina sérica inicial o alcanzan enfermedad renal crónica estadio 5, diálisis o trasplante, o muerte entre el grupo que recibe 25 OH vitamina D y el grupo sin tratamiento activo |
|
E.2.2 | Secondary objectives of the trial |
- Compare proteinuria decrease between groups - To evaluate and compare the safety and tolerance to treatment with 25 OH vitamin D - Compare cardiovascular morbidity and mortality (death from CV causes , MI, hospitalization for heart failure , coronary angiography and / or coronary revascularization , stroke, and amputation and / or revascularization of lower limbs ) between groups - Compare the time of diagnosis of secondary hyperparathyroidism (PTH KDOQI > 250 pg / mL ) between groups |
- Comparar la reducción de proteinuria entre los grupos - Evaluar y comparar la seguridad y tolerancia al tratamiento con 25 OH vitamina D entre los grupos - Comparar la Morbi-mortalidad cardiovascular (muerte de causa CV, IAM, hospitalización por IC, coronariografía y/o revascularización coronaria, ACVA, amputación y/o revascularización de MMII) entre los grupos - Comparar el tiempo del diagnóstico de hiperparatirodismo secundario (PTH KDOQI > 250 pg/mL) entre los grupos |
