Increased Blood-Brain Barrier Permeability and Cognitive Impairment in Patients With ESKD.

ABSTRACT:

Introduction

Chronic kidney disease (CKD) is associated with an increased risk of cognitive impairment. This cognitive impairment is associated with an increased permeability of blood-brain barrier (BBB) in rodents with CKD, linked to activation of aryl hydrocarbon receptor (AhR) by indoxyl sulphate (IS). The objective of the BREIN study was to confirm the increased BBB permeability in humans with CKD.

Method

The BREIN comparative study (NCT04328415) prospectively included patients with end-stage kidney disease (ESKD) and controls healthy volunteers matched in age, sex, and level of education to a patient. In all participants, BBB permeability was quantified by brain ^99mTc-DTPA SPECT/CT as a percentage of injected activity (% IA). A battery of neurocognitive tests
