Specific Aim: Compare the endothelial function, arterial stiffness and components of metabolic syndrome of childhood Acute Lymphoblastic Leukemia (ALL) survivors to healthy sibling controls. Plan: A cross sectional study comparing ALL survivors to sibling controls including measures of endothelial function and arterial stiffness obtained form a peripheral artery tonometry device, height, weight, waist circumference, fasting lipid, glucose and insulin.

Study Population

This descriptive, healthy sibling control study will utilize a convenience sample of 20 childhood ALL survivors, recruited from the Survivorship Program at Johns Hopkins (SPJH). The study will be introduced to survivors/parent/guardians during routine clinic visits. If they are interested in participation the consent form for both the survivor and sibling will be reviewed and taken home to discuss with the sibling and other family members. Follow-up phone call and questions will be encouraged. If all parties agree to participate an appointment will be set up to enroll the survivor/sibling and face to face informed consent will be obtained.

A second method for recruitment will include mailings (see attached) to ALL survivors seen/treated at Johns Hopkins. Letters will include phone and email contacts to acquire further information and a post card to decline further contact.


Inclusion Criteria:



  1. Ages 8-28 (8 is chosen as lower age limit because developmental understanding will allow survivor to follow instructions for procedures, 28 is chosen as upper limit to include age ranges seen for treatment in the pediatric program)
  2. Off therapy for at least 6 months and not more than 10 years (6 months


  1. Biological sibling
  2. Ages 8-28 (when more than one sibling is available the one closest in age will be chosen.))

Exclusion Criteria:

  1. Uncontrolled medical conditions that could interfere with participation or interpretation of results
  2. History of relapsed ALL or history of bone marrow transplantation
