Current approaches to prevent and treat GVHD after allogeneic stem cell transplantation.

ABSTRACT: Allogeneic hematopoietic cell transplantation is a potentially curative therapy for many malignant and nonmalignant hematologic diseases. Graft-versus-host disease (GVHD) is a common complication after transplantation and remains a major cause of morbidity and mortality, limiting the success of a potentially curative transplant. This paper reviews the current and emerging strategies in GVHD prevention and treatment. New insights are leading the way to the development of novel targeted approaches to minimize the risk of disease relapse and infection. Continued collaborative efforts to conduct high-quality, multicenter clinical trials with standard end points and risk stratification are needed to determine the optimal approach to minimize GVHD and limit toxicities.

Project description:BACKGROUND:There are very few studies investigating metabolic biomarkers to predict acute graft-versus-host disease (aGVHD) after allogeneic hematopoietic stem cell transplantation (HSCT). Metabolic models can provide a framework for analyzing the information-rich omics data sets in this setting. METHODS:Four hundred and fifty-six samples from one hundred and fourteen consecutive patients who underwent HSCT from January 2012 to May 2014 were collected for this study. The changes in serum metabolite levels were investigated using a gas chromatography-mass spectrometry-based metabolomics approach and underwent statistical analysis. RESULTS:Significant metabolic changes were observed on day 7. The stearic acid/palmitic acid (SA/PA) ratio was effective in the diagnosis of grade II-IV aGVHD. Multivariate analysis showed that patients with high SA/PA ratios on day 7 after HSCT were less likely to develop II-IV aGVHD than patients with low SA/PA ratios (odds ratio [OR] = 0.06, 95% CI 0.02-0.18, P < 0.001). After the adjustment for clinical characteristics, the SA/PA ratio had no significant effect on overall survival (hazard ratio [HR] = 1.95, 95% CI 0.92-4.14, P = 0.08), and patients in the high SA/PA ratio group were significantly more likely to relapse than those in the low ratio group (HR = 2.26, 95% CI 1.04-4.91, P = 0.04). CONCLUSION:Our findings suggest that the SA/PA ratio on day 7 after HSCT is an excellent biomarker to predict both aGVHD and relapse. The serum SA/PA ratio measured on day 7 after transplantation may improve risk stratification for aGVHD and relapse after allogeneic stem cell transplantation.
