  • All Genders

Study Summary

The Vendys II, an FDA-approved device, uses finger digital thermal monitoring (DTM) after a period of blood flow restriction to evaluate vascular health. This study will evaluate the feasibility of using this device to measure the Vascular Reactivity Index (VRI) in children and adolescents/young adults (AYA) undergoing hematopoietic cell transplantation (HCT).

Eligibility Criteria

Inclusion

Inclusion Criteria for HCT candidates:

  • Children, adolescents and young adults (AYA) 6-26 years of age who are HCTcandidates

  • Recipients within 30 days prior to or within 14 days after autologous and allogeneicHCT.

-. Any preparative regimen.

  • Willing and eligible to enroll on PA19-0756

Inclusion Criteria for Healthy Donors:

  • Healthy HCT donors between the ages of 6-26 years of age.

Exclusion

Exclusion Criteria:

  • Any subject who does not consent/assent to participation.

-. Any subject with an injury or deformation to the index finger which preventsproper fit of the device.

  • Any subject with skin toxicity or neuropathy which prevents comfortable use of thedevice.

Study Description

Primary Objective:

-Assess the feasibility of the use of VENDYS-II in children and AYA as a measure of vascular endothelial function, where feasibility is defined as completion of the evaluation by at least 70% of consented participants.

Secondary Objective:

-Summarize the incidence of any adverse events that precludes completion of assessment of endothelium-dependent vasodilation using the Vendys II in children and AYA.
