Manejo de la osteoporosis en el paciente con enfermedad renal crónica (Estudio ERCOS): un desafío en la asistencia nefrológica

Abstract

Fracture risk assessment in patients with chronic kidney disease (CKD) has been included in the Chronic Kidney Disease-Mineral and Bone Disorders (CKD-MBD) complex in international and national nephrology guidelines, suggesting for the first time the assessment of bone mineral density (BMD) if the results will impact treatment decisions. However, there is very little information on actual clinical practice in this population. The main objective of the ERC-Osteoporosis (ERCOS) study is to describe the profile of patients with CKD G3-5D with osteoporosis (OP) and/or fragility fractures treated in specialized nephrology, rheumatology and internal medicine clinics in Spain. Fifteen centers participated and 162 patients (mostly women [71.2%] postmenopausal [98.3%]) with a median age of 77 years were included. Mean estimated glomerular filtration rate (eGFR) was 36ml/min/1.73m2 and 38% of the included patients were on dialysis. We highlight the high frequency of prevalent fragility fractures ([37.7%], mainly vertebral [52.5%] and hip [24.6%]), the disproportionate history of patients with glomerular disease compared to purely nephrological series (corticosteroids) and undertreatment for fracture prevention, especially in nephrology consultations. This study is an immediate call to action with the dissemination of the new, more proactive, clinical guidelines, and underlines the need to standardize a coordinated and efficient multidisciplinary care/therapeutic approach to these patients to avoid current discrepancies and therapeutic nihilism.
