Microvascular and Fibrosis Imaging Study

September 10, 2020 updated by: Duke University

Mechanistic Study: Non-Invasive Cutaneous Microvascular and Fibrosis Imaging of Patients With Systemic Sclerosis, Sickle Cell Disease and Chronic Graft-Versus-Host Disease (GVHD) Compared to Healthy Subjects

In this study, Laser Doppler Flowmetry (LDF), Laser Doppler Imaging (LDI), Orthogonal Polarization Spectral Imaging (OPSI), Nail fold video capillaroscopy (NVC) and Optical Coherence Tomography (OCT) will be used to assess differences in microvascular function and density of oral mucosa and skin in subjects with 1) autoimmune diseases with cutaneous involvement: systemic sclerosis (SSc), morphea, dermatomyositis, cutaneous lupus and vasculitis, 2) sickle cell disease (SCD) and 3) chronic graft-versus-host disease (GVHD) compared to healthy subjects. The microvascular changes will be compared to overall treatment response in patients with scleroderma and chronic GVHD as assessments will be made before and after the patients start treatment for their diseases and determine if these imaging techniques provide valuable and reproducible data when assessing a patient's response to treatment for those diseases. In addition, the application of Acoustic Radiation Force Impulse (ARFI) in determining cutaneous thickness in patients with SSc, GVHD and morphea will be evaluated.

The investigators hypothesize that the vascular and dermal structures are altered in patients with autoimmune disease, SCD and chronic GVHD. In addition, they hypothesize that imaging modalities such as LDF, LDI, OCT, NVC, OPSI and ARFI can quantify such structural alterations and can be used to 1) detect early disease activity, 2) quantify and assess response to therapy and 3) quantify and correlate with overall disease activity.

Cohorts and Interventions

Group / Cohort
Intervention / Treatment
Systemic Sclerosis
Patients with SSc will have imaging studies performed at baseline and at 3, 6, 9, 12, 15, 18, 21 and 24 months.
GVHD
Patients with GVHD will have imaging studies performed at baseline and at 3, 6, 9, 12, 18 and 24 months.
Undergoing HSCT
Patients who are about to undergo HSCT will have imaging studies performed at 1 week pre-transplantation, day 40 and 80 post transplantation and at 3 months, 6 months, 12 months 18 months and 24 months post-transplant.
Controls
Healthy Controls and Controls with hematologic and solid organ malignancies and dermatitis will have imaging studies performed at a single point in time.
Sickle cell disease
Patients with SCD will have imaging studies performed at baseline and at 3, 6, 9, 12, 15, 18, 21 and 24 months.
Cutaneous fibrosing disorder
Patients with active cutaneous fibrosing disorder will have imaging studies performed at a single point in time.
