PTH levels and not serum phosphorus levels are a predictor of the progression of kidney disease in elderly patients with advanced chronic kidney disease.

Background: At present, there is a high incidence of elderly patients with advanced chronic kidney disease (CKD) and it is important to know the long term progression and the factors that influence it.

Objectives: To analyse the progression of advanced CKD in elderly patients and the influence of bone-mineral metabolism.

Methods: Retrospective study of 125 patients ≥70years of age with CKD stages 4-5 who started follow-up from January 1, 2007 to December 31, 2008, showing the progression of CKD (measured by the slope of the regression line of the estimated glomerular filtration rate [eGFR] by MDRD-4) over 5years.

Survival of patients ≥70 years with advanced chronic kidney disease: Dialysis vs. conservative care.

Introduction: The number of elderly patients with advanced chronic kidney disease (ACKD) has increased in recent years, and the best therapeutic approach has not been determined due to a lack of evidence.

Objectives: To observe the progression of elderly patients with ACKD (stages 4 and 5) and to compare the survival of stage 5 CKD patients with and without dialysis treatment.

Material And Methods: All patients ≥70 years who began ACKD follow-up from 01/01/2007 to 31/12/2008 were included, and their progression was observed until 31/12/2013.
