Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Patients with chronic kidney disease (CKD) who require a kidney biopsy (native and transplant) will undergo contrast-enhanced kidney magnetic resonance imaging (MRI). The maximum anticipated time of scanning will be 1 hour, and participants will undergo a single parametric scan (utilising 8 different MRI techniques including volumetry, T1/T2/T2* mapping, phase contrast, diffusion weighted imaging, dynamic contrast enhancement and post-contrast T1-mapping) within 1 month following their kidney biopsy. A single intravenous injection of a gadolinium-based contrast agent (Dotarem) will be administered at 0.05mmol/kg via a peripheral intravenous cannula. The scan will be conducted by a MRI radiographer, and an MRI safety checklist will be conducted for each participant prior to scanning.

Diagnosis / Prognosis
Comparator / control treatment
The control group will include healthy volunteers without CKD who will undergo the same contrast-enhanced magnetic resonance imaging as the CKD cohort, however will not undergo kidney biopsy.

Efficacy
Statistical methods / analysis
A healthy control group (n=10) will determine a normal MRI reference range for baseline comparison. The disease control group will include those with minimal change disease on kidney biopsy as there will be no evidence of tubulointerstitial fibrosis. A derivation cohort (n=24) will be recruited to develop the model and a validation cohort (n=24) will be recruited to test the accuracy and sensitivity of the model. A multivariable linear regression model will be tested to determine the correlation between the MRI techniques outlined above and severity of kidney fibrosis on biopsy, level of eGFR and degree of albuminuria. All statistical tests will be performed at a 0.05 level of significance.

Summary
Brief summary
Chronic kidney disease (CKD) is increasingly becoming more common, and is associated with increased disability and death rates. The best predictor for progression to kidney failure is the amount of kidney scarring detected on a biopsy. Biopsies are useful however are limited by their invasive nature and inability to collect large or multiple samples. MRI is used in other organs like the heart and the liver to check for scarring, but is not yet available for the kidney. The NIMBLE-CKD project aims to develop an MRI marker to estimate the amount of kidney scarring by comparing images with biopsy samples. Ultimately this will provide a less intrusive and safer way to detect and monitor CKD, with a hope to guide early treatment and prevent kidney failure.
