Osteoporosis in Advanced Kidney Disease

Depression disproportionately affects patients with kidney disease, including those with nondialysis chronic kidney disease, end-stage kidney disease requiring dialysis, and kidney transplant recipients. Patients across the spectrum of kidney disease should be screened for depression every 6 to 12 months using self-report questionnaires, followed by an interview with a clinician to confirm the presence of sadness or anhedonia when depressive symptoms are identified. Pharmacologic treatment with selective serotonin reuptake inhibitors has not consistently shown benefit compared with placebo and may be associated with serious adverse outcomes including cardiovascular events, bleeding, and fractures. However, based on the availability of alternative therapies, a watchful trial with close monitoring for therapeutic and adverse effects is reasonable. Several clinical trials have suggested that cognitive behavioral therapy and physical activity improve depressive symptoms when compared with a control group. Given the low risk associated with these therapies, they should be recommended to patients who have access and are amenable to such interventions. Future trials are needed to study therapeutic options for depression in nondialysis chronic kidney disease, peritoneal dialysis, or kidney transplant recipients, as well as alternative pharmacologic therapy and combination therapies.Osteoporosis and fractures are common in persons with advanced chronic kidney disease (CKD) and on maintenance dialysis.
Although the diagnosis of osteoporosis in this population can be difficult, imaging, especially with dual-energy x-ray absorptiometry (DXA), is helpful in identifying persons with CKD at the highest risk of fracture. Although blood biomarkers including parathyroid hormone and bone-specific alkaline phosphatase concentrations can aid in assessing bone turnover state, bone biopsy remains the gold standard in determining bone turnover in persons with advanced kidney disease and osteoporosis. With the increasing armamentarium of osteoporosis drugs, it now may be possible to prevent many fractures in advanced CKD. Unfortunately, data on these drugs are limited in persons with advanced CKD. Clinicians, aided by advances in imaging, biomarkers, and bone biopsy can now use these novel agents to target bone turnover abnormalities such as adynamic bone disease and high bone turnover disease. This review will discuss the most recent literature surrounding the diagnosis, management, and monitoring of osteoporosis and fractures in persons with advanced CKD or on maintenance dialysis.
