Diagnosing bone disease in patients with kidney issues

Diagnosis of Renal Osteodystrophy in Patients With Reduced Renal Function Can 18F-PET Replace Bone Histomorphometry

Observational Herlev Hospital · NCT03716128

This study is testing if a special imaging scan can help doctors better understand bone health in patients with kidney problems and different levels of parathyroid hormone.

What this trial studies

This observational study aims to characterize bone morphology in patients with reduced renal function and varying levels of parathyroid hormone (PTH). It investigates the use of 18-Fluoride Positron Emission Tomography (18F-PET) as a non-invasive method to assess bone turnover and its correlation with bone histomorphologic changes. Patients with suspected high or low turnover bone disease will undergo a bone biopsy and an 18F-PET scan to determine the effectiveness of this imaging technique in differentiating between the two conditions.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older with reduced renal function and specific PTH levels.

Not a fit: Patients with ongoing malignancies, allergies to tetracycline, or those who are pregnant may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved diagnostic methods for renal osteodystrophy, allowing for better-targeted treatments.

How similar studies have performed: While the use of 18F-PET in this context is relatively novel, similar imaging techniques have shown promise in other studies assessing bone health.
