Prediction of cardiovascular disease among hematopoietic cell transplantation survivors.

ABSTRACT: Cardiovascular disease (CVD) is a leading cause of late morbidity and mortality in hematopoietic cell transplantation (HCT) survivors. HCT-specific CVD risk prediction models are needed to facilitate early screening and prevention. In the current study, patients who underwent HCT at City of Hope (COH) and survived 1-year free of clinically evident CVD (N = 1828) were observed for the development of heart failure (HF) or coronary artery disease (CAD) by 10-years from index date (1 year from HCT). CVD occurred in 135 individuals (92 HF, 43 CAD). Risk prediction models were developed for overall CVD (HF and/or CAD) using COH-derived integer risk scores. Risk scores based on selected variables (age, anthracycline dose, chest radiation, hypertension, diabetes, smoking) achieved an area under the curve (AUC) and concordance (C) statistic of 0.74 and 0.72 for CVD; these varied from 0.70 to 0.82 according to CVD subtype (HF or CAD). A Fred Hutchinson Cancer Research Center case cohort (N = 580) was used to validate the COH models. Validation cohort AUCs ranged from 0.66 to 0.75. Risk scores were collapsed to form statistically distinct low-, intermediate-, and high-risk groups, corresponding to 10-year cumulative incidences of CVD of 3.7%, 9.9%, and 26.2%, respectively. Individuals in the high- and intermediate-risk groups were at 7.8-fold (95% confidence interval, 5.0-12.2) and 2.9-fold (95% confidence interval, 1.9-4.6) risk of developing CVD (referent group: low risk). These validated models provide a framework on which to modify current screening recommendations and for the development of targeted interventions to reduce the risk of CVD after HCT.

Project description:Sickle cell disease (SCD) is a severe autosomal recessively inherited disorder of the red blood cell characterized by erythrocyte deformation caused by the polymerization of the abnormal hemoglobin, which leads to erythrocyte deformation and triggers downstream pathological changes. These include abnormal rheology, vaso-occlusion, ischemic tissue damage, and hemolysis-associated endothelial dysfunction. These acute and chronic physiologic disturbances contribute to morbidity, organ dysfunction, and diminished survival. Hematopoietic cell transplantation (HCT) from HLA-matched or unrelated donors or haploidentical related donors or genetically modified autologous hematopoietic progenitor cells is performed with the intent of cure or long-term amelioration of disease manifestations. Excellent outcomes have been observed following HLA-identical matched related donor HCT. The majority of SCD patients do not have an available HLA-identical sibling donor. Increasingly, however, they have the option of undergoing HCT from unrelated HLA matched or related haploidentical donors. The preliminary results of transplantation of autologous hematopoietic progenitor cells genetically modified by adding a non-sickling gene or by genomic editing to increase expression of fetal hemoglobin are encouraging. These approaches are being evaluated in early-phase clinical trials. In performing HCT in patients with SCD, careful consideration must be given to patient and donor selection, conditioning and graft-vs.-host disease regimen, and pre-HCT evaluation and management during and after HCT. Sociodemographic factors may also impact awareness of and access to HCT. Further, there is a substantial decisional dilemma in HCT with complex tradeoffs between the possibility of amelioration of disease manifestations and early or late complications of HCT. The performance of HCT for SCD requires careful multidisciplinary collaboration and shared decision making between the physician and informed patients and caregivers.

Project description:Hematopoietic stem cell transplantation (HCT) survivors are burdened by a high prevalence and early onset of chronic diseases. Healthy dietary patterns have been associated with lower risks of chronic health conditions in the general population. HCT survivors are susceptible to multiple complications that may result in chronic illness. Unfortunately, no study to date has comprehensively documented the adherence of HCT survivors to the Dietary Guidelines for Americans (DGA), which are designed specifically to provide guidance for making healthy food choices. The primary aim of this study was to evaluate diet quality and nutrient intake adequacy of HCT survivors. A secondary aim was to assess these survivors' willingness to take part in a future dietary intervention. The dietary intake of adults who had undergone autologous or allogeneic HCT for a hematologic disease and were at least 1 year post-transplantation was assessed using the Block 2014 food frequency questionnaire, and diet quality was estimated using the Healthy Eating Index 2015. Nutrient intake adequacies of the group were estimated by the estimated average requirement cutpoint method. Survivors' (n = 90) HEI-2015 scores averaged 61.6 ± 1.1. Adherence to a good-quality diet was reported by only 10% of survivors. Intakes of vitamins A, C, and D, as well as magnesium and calcium, suggested inadequacy. Fiber intake at 8.9 g per 1000 kcal/day fell below the recommended adequate intake. "Change in taste" was associated with lower quality of diet (P = .02). HCT survivors within 2 years post-transplantation were more receptive than survivors beyond 2 years to participating in a dietary intervention (95% versus 65%; P = .0013). Adult HCT survivors reported less-than-optimal adherence to the 2015-2020 DGA and had numerous shortfall nutrient intakes; however, their willingness to participate in a dietary intervention was relatively high. These findings reinforce the need to incorporate nutrition into HCT survivor care.
