Abstract

This study examined the effects of hematopoietic cell transplantation (HCT) and associated preparative regimens on vascular structure and function. Measures of carotid artery stiffness and brachial artery endothelial-dependent dilation were obtained in patients who had survived ≥ 2 years after HCT for hematologic malignancy and were diagnosed at ≤21 years. HCT survivors (n = 108) were examined: 66 received total body irradiation (TBI) alone or with a low-dose cranial radiation boost (TBI±LD-CRT), 19 received TBI plus high-dose cranial radiation (TBI+HD-CRT), and 23 received a chemotherapy-only preparative regimen (CHEMO). Siblings (n = 83) were invited to participate as control subjects. Although endothelial-dependent dilation did not differ between siblings and HCT survivors, carotid cross-sectional compliance, cross-sectional distensibility, diameter compliance, and diameter distensibility were greater in siblings than HCT survivors. Comparing the HCT preparative regimens, carotid cross-sectional compliance, cross-sectional distensibility, diameter compliance, diameter distensibility, and incremental elastic modulus were significantly lower in the TBI+HD-CRT group compared with siblings or with TBI±LD-CRT and CHEMO treatment groups. Cross-sectional distensibility and diameter compliance were significantly lower in the TBI±LD-CRT group compared with siblings. TBI±LD-CRT and CHEMO groups did not differ from each other in these vascular measures. HCT preparative regimens containing TBI+HD-CRT resulted in greater arterial decrements, indicating increased risk for cardiovascular disease.
