About this study

Official title: Metabolic Syndrome Following Transplant for Leukemia

RATIONALE: Gathering information about how often metabolic syndrome occurs in young survivors of childhood leukemia who have undergone stem cell transplant may help doctors learn more about the disease and the long-term effects of leukemia treatment. It may also help improve the quality of life for future cancer survivors.

PURPOSE: This clinical trial is studying metabolic syndrome in adolescent and young adult survivors of childhood leukemia who have undergone stem cell transplant.

Read the detailed description

OBJECTIVES:

  • To determine the prevalence of metabolic syndrome in adolescent and young adult survivors of childhood leukemia who have undergone hematopoietic stem cell transplantation (HSCT) and compare the extent to which prevalence is higher in HSCT survivors than in age- and gender-matched population norms derived from the Third National Health and Nutrition Examination Survey (NHANES III).
  • To evaluate the relationship between insulin resistance and risk factors associated with metabolic syndrome (e.g., hypertension, obesity, hyperinsulinemia, and dyslipidemia) as measured by euglycemic insulin clamp, fasting serum insulin, glucose, lipids (total cholesterol, triglycerides, LDL-C, and HDL-C), blood pressure and anthropometric measurements, and DEXA scan in these patients and compare to age- and gender-matched population norms.
  • To assess the extent to which prevalent obesity and insulin resistance are correlated with other factors that have been identified in the causal pathway associated with the development of metabolic syndrome and that may be altered after HSCT, including growth hormone secretion, adipokines (adiponectin and leptin), and inflammatory mediators (interleukin-6, tumor necrosis factor-α, and C-reactive protein).
  • To evaluate the association of metabolic syndrome and early signs of impaired endothelial function and cardiovascular changes.
  • To evaluate health behaviors related to prevention of cardiovascular disease, diabetes, and obesity, including a physical activity assessment, a dietary assessment, and a health knowledge assessment that will be used in the analyses of metabolic syndrome, growth hormone deficiency, and indicators of cardiovascular disease.

OUTLINE: Patients are stratified according to post-transplant follow-up period (2-9 years vs 10-15 years vs > 15 years).

Patients and their siblings undergo physical examination, a review of medical and family history, and blood pressure and anthropometric measurements. Patients and their siblings also undergo blood sample collection for laboratory studies (including analysis of C-reactive protein and CBC; lipid profile and triglycerides; leptin and adipokines; free thyroxine, TSH, IGF1, IGF3, and LH; and estradiol [females] or testosterone [males]); urine sample collection for microalbumin determination; and other study procedures (including euglycemic insulin clamp study; body composition and bone density [DEXA] study; bone-age x-ray [for patients < 18 years of age]; and vascular studies). Patients also undergo growth hormone stimulation testing.

Patients and their siblings complete questionnaires about their physical activity, dietary habits, and health knowledge.

PROJECTED ACCRUAL: A total of 193 childhood leukemia survivors and 193 healthy siblings will be accrued for this study.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Comparison of the prevalence of metabolic syndrome in adolescent and young adult survivors of childhood leukemia who have undergone hematopoietic stem cell transplantation (HSCT) with age- and gender-matched controls

    Measured: ≥2 years post-HSCT

  2. Comparison of insulin resistance in patients with age- and gender-matched controls

    Measured: ≥2 years post-HSCT

  3. Correlation between insulin sensitivity and risk factors associated with metabolic syndrome

    Measured: ≥2 years post-HSCT

  4. Influence of time since transplant on insulin resistance

    Measured: ≥2 years post-HSCT

  5. Peak growth hormone secretion in patients with insulin resistance and in those without

    Measured: ≥2 years post-HSCT

  6. Growth hormone deficiency in patients with metabolic syndrome and in those without

    Measured: ≥2 years post-HSCT

  7. Association of interleukin-6, tumor necrosis factor-α, C-reactive protein, and leptin with insulin resistance and central obesity

    Measured: ≥2 years post-HSCT

  8. Correlation of adiponectin with insulin resistance and central obesity

    Measured: ≥2 years post-HSCT

  9. Differences in markers for endothelium dysfunction and early indicators of cardiovascular disease

    Measured: ≥2 years post-HSCT

  10. Difference in important health behaviors related to obesity and cardiovascular disease between patients with metabolic syndrome and those without

    Measured: ≥2 years post-HSCT

Questions about this trial

What is this clinical trial studying?

An observational study of Cardiovascular Complications and Leukemia, run by Fred Hutchinson Cancer Center at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 3 Dec 2012. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Comparison of the prevalence of metabolic syndrome in adolescent and young adult survivors of childhood leukemia who have undergone hematopoietic stem cell transplantation (HSCT) with age- and gender-matched controls (time frame: ≥2 years post-HSCT). The study lists 10 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Dec 2012.
