Assessment of Endothelial Function and IMT in Survivors Hodgkin's Lymphoma Patients
Disease free survival of Hodgkin's disease (HD) patients has improved dramatically over the
past few decades. With the dramatic advance in patient's survival, the prevention and
treatment of long-term adverse effects of chemotherapy and radiotherapy has become a major
focus of interest. HD survivors have excess mortality compared with the age-matched general
population, even after excluding disease relapse. A considerable proportion of the excess
mortality is due to cardiovascular disease (CVD), principally ischemic heart disease and
stroke.
The proposed study will assess endothelial function in HD survivors, using the non-invasive
technique of brachial artery flow-mediated dilation (FMD), by high-resolution
ultrasonography. We will also assess IMT. The results of these tests are independent
predictors of atherosclerosis disease progression and cardiovascular event rates. This is a
prospective study comprising 40 young-adult (aged 18-30 years) . The study will comprise 40
survivors of HD: 20 patients treated with chemotherapy and radiotherapy to the chest and 20
patients treated with chemotherapy alone. The patients will be compared to age and
sex-matched patients from the data base of the endothelial function laboratory at the heart
institute of the Sheba Medical Center. In addition to brachial artery endothelial function
assessment, the patients will also undergo a physical examination including anthropometric
measurements (height, weight, waist and hip circumference), and blood pressure. The
evaluation will also include blood tests for glucose, lipid profile, CRP, AST, ALT and
insulin. A medical history including smoking history and family history of CVD and
dyslipidemia will be obtained.
Patients treated with radiotherapy to the chest will be compared to patients treated with
chemotherapy alone and both patients will be compared to healthy controls. The patients will
be characterized by age, risk factors for coronary heart disease and endothelial function as
assessed by brachial artery FMD. We will establish the rate of endothelial function
abnormalities in survivors of HD and its correlation with the other risk factors.
