The metabolic profiles of patients with autologous hematopoietic stem cell transplantation with graft versus host disease.

Abstract

e24010 Background: Graft versus host disease (GvHD) is a serious inflammatory complication of hematopoietic stem cell transplant (HSCT) and a leading contributor to morbidity and mortality in HSCT patients. Previous studies have identified increased risk of cardiovascular death in HSCT patients who develop GvHD and characterized echocardiographic changes associated with chronic GvHD. However, details of the metabolic derangements in HSCT patients who develop GvHD remain poorly studied. Methods: This is a retrospective study of patients who underwent HSCT at H. Lee Moffitt Cancer Center and later developed severe chronic GVHD at 1 year. Metabolic data including weight, blood pressure, and lipid profile were recorded at baseline and at 1 year after HSCT. Results: Between January 1, 2010, and December 31, 2020, 1805 patients who received allogeneic HSCT were reviewed. At 1 year, 371 patients (20.5%) had severe GVHD. Compared to baseline, patients had higher total cholesterol (209 vs 183 mg/dL, P < 0.001), high-density lipoprotein (61 vs 47 mg/dL, P < 0.001), and triglycerides (211 vs 163 mg/dL, P < 0.001) at 1 year of follow up. Low-density lipoprotein values were not significantly different (107 vs 102 mg/dL, p = 0.15). Patient weight was significantly less at 1 year (163 vs 183 lbs, p < 0.001). Although blood pressure was not significantly different between baseline and 1 year, more patients were placed on antihypertensive medications at 1 year (50% vs 31%). Conclusions: This study finds that patients who undergo allogeneic HSCT and subsequently develop severe GVHD are at risk for metabolic derangements that may worsen cardiovascular health. We specifically demonstrate an increased need for antihypertensive therapy and elevations in total cholesterol and serum triglycerides. Further research is needed on the impact of these derangements on major adverse cardiac events and the role of cardiovascular risk factor management in these patients.
