The Role of Galectin-3 in Predicting Acute GvHD and Mortality after Reduced Intensity Allo-HCT: Findings from a BMT-CTN Biorepository Study in Bone Marrow Transplantation<\/p>\n

Bone marrow transplantation (BMT) is a life-saving procedure for patients with various hematological malignancies and other disorders. However, one of the major complications associated with BMT is graft-versus-host disease (GvHD), which occurs when the transplanted immune cells recognize the recipient’s tissues as foreign and attack them. Acute GvHD can lead to significant morbidity and mortality, making it crucial to identify biomarkers that can predict its occurrence and severity.<\/p>\n

In recent years, researchers have focused on galectin-3, a protein involved in various biological processes, including inflammation and immune response. Galectin-3 has been implicated in the pathogenesis of several diseases, including cancer, fibrosis, and cardiovascular diseases. Its role in acute GvHD and mortality after reduced intensity allo-HCT (allogeneic hematopoietic cell transplantation) has also gained attention.<\/p>\n

A recent study conducted by the Blood and Marrow Transplant Clinical Trials Network (BMT-CTN) biorepository aimed to investigate the predictive value of galectin-3 in acute GvHD and mortality after reduced intensity allo-HCT. The study included 1,000 patients who underwent allo-HCT between 2008 and 2015. Blood samples were collected before transplantation, and galectin-3 levels were measured using a validated assay.<\/p>\n

The findings of the study revealed that higher pre-transplant galectin-3 levels were associated with an increased risk of developing acute GvHD. Patients with galectin-3 levels above a certain threshold had a significantly higher incidence of acute GvHD compared to those with lower levels. This suggests that galectin-3 could serve as a potential biomarker for predicting the development of acute GvHD in patients undergoing reduced intensity allo-HCT.<\/p>\n

Furthermore, the study also found that elevated galectin-3 levels were associated with increased mortality after allo-HCT. Patients with higher galectin-3 levels had a higher risk of death within the first year post-transplantation. This association remained significant even after adjusting for other known risk factors, such as age, disease type, and donor characteristics. These findings suggest that galectin-3 could also serve as a prognostic marker for mortality in patients undergoing reduced intensity allo-HCT.<\/p>\n

The exact mechanisms by which galectin-3 contributes to the development of acute GvHD and increased mortality are not fully understood. However, it is believed that galectin-3 plays a role in promoting inflammation and immune dysregulation, which are key factors in the pathogenesis of acute GvHD. Galectin-3 may also contribute to tissue damage and fibrosis, further exacerbating the complications associated with GvHD.<\/p>\n

The identification of galectin-3 as a potential biomarker for predicting acute GvHD and mortality after reduced intensity allo-HCT has significant clinical implications. Early identification of patients at high risk for developing acute GvHD can allow for closer monitoring and timely intervention, potentially improving patient outcomes. Additionally, the use of galectin-3 as a prognostic marker for mortality can help identify patients who may benefit from more aggressive treatment strategies or closer follow-up.<\/p>\n

Further research is needed to validate these findings and determine the optimal cutoff values for galectin-3 levels in predicting acute GvHD and mortality. Additionally, investigating the underlying mechanisms by which galectin-3 contributes to these outcomes could provide insights into potential therapeutic targets for preventing or treating acute GvHD.<\/p>\n

In conclusion, the BMT-CTN biorepository study has shed light on the role of galectin-3 in predicting acute GvHD and mortality after reduced intensity allo-HCT. Galectin-3 levels before transplantation can serve as a potential biomarker for identifying patients at high risk for developing acute GvHD and experiencing increased mortality. These findings have important implications for risk stratification and personalized treatment approaches in the field of bone marrow transplantation.<\/p>\n
