Investigating Vascular Properties of HEMI and SPG Signals in Individuals With or at Risk for Chronic Kidney Disease (STIMULUS-CKD)

2026년 6월 4일 업데이트: Institut National de la Santé Et de la Recherche Médicale, France
This prospective, single-center clinical investigation conducted in France will evaluate two non-invasive investigational devices (HEMI and SPG-NINOX) designed to assess microcirculation in adults. The study will include 165 participants divided into five groups (33 per group): healthy volunteers, patients with hypertension without chronic kidney disease (CKD), patients with type 2 diabetes without CKD, patients with moderate CKD, and patients with severe CKD. The primary objective is to compare baseline small vessel pressure measured with the HEMI (Multi-spectral optical system for microcirculation hemodynamics) device across groups in order to identify microvascular alterations associated with cardiometabolic and renal disease. Secondary objectives include assessment of microvascular responses after post-ischemic hyperemia, evaluation of SPG-derived (Speckle plethysmography) small vessel flow and volume parameters, comparison with reference vascular measurements (including SphygmoCor and ultra-high frequency ultrasound), and evaluation of feasibility, acceptability, and measurement reproducibility. Participation is non-randomized, based on participants' pre-existing clinical condition, and study procedures are non-invasive with an expected visit duration of approximately 60 minutes.
