ORAL CLINICAL OUTCOMES OF GRAFT-VERSUS-HOST DISEASE IN 147 PATIENTS SUBMITTED TO ALLOGENEIC HEMATOPOIETIC STEM CELL TRANSPLANTATION: AN EXPERIENCE OF A SINGLE CANCER CENTER

The aim of the study was to systematize and summarize the current available data on ruxolitinib use in patients with myelofibrosis (MF) prior to allogeneic hematopoietic stem cell transplantation (allo-HSCT) to improve its results. The review includes data from foreign and domestic articles found in the PubMed and elibrary.ru databases describing the results of the use of ruxolitinib in patients with MF prior to allo-HSCT, including clinical cases, original scientific studies and reviews. It is reported that ruxolitinib therapy is safe, reduces mortality in the early post-transplantation period, reduces the incidence of acute and chronic graft-versus-host disease, and decreases the frequency of relapses. Clinical improvement with ruxolitinib therapy prior to allo-HSCT can be considered a prognostically favorable factor.

Cd26 Expression

BACKGROUND: Allogeneic hematopoietic stem cell transplantation (ASCT) is the preferred treatment option for patients with several hematologic disorders and immunodeficiency syndromes. Graft versus host disease (GVHD) is an immune mediated post-transplant complication which has a major impact on long term transplant outcomes. OBJECTIVE: Current efforts are focused on identification of new markers that serve as potential predictors of GVHD and other post-transplant clinical outcomes. METHODS: This study includes donor harvests collected from twenty-three allogeneic donors during period 2008–2009 and respective transplant recipients followed for clinical outcomes till March 2019. Percent CD26+ and CD34+ cells in donor harvest were analyzed using flow cytometry. Percent expression and infused dose of CD26+ and CD34+ cells were evaluated for association with various clinical outcomes. RESULTS: Total 23 healthy donors 28 years (13 males), and transplant recipients with median age 24 years (17 males) formed the study cohort. The diagnosis included malignant (n= 13) and non-malignant (n= 10) disorders. Median CD34brCD45lo HSC expression was 057% (IQR 024–103) while median CD26 expression was 1964% (IQR 896–3356) of all nucleated cells. CD26 expression was associated with donor age (P= 0.37). CD26 percent expression correlated with WBC engraftment (P= 0.015) and with acute GVHD (P= 0.023) whereas infused CD26 cell dose correlated with WBC engraftment (P= 0.004) and risk of CMV reactivation (P= 0.020). There was no statistically significant correlation of either CD26 expression or cell dose with chronic GVHD, EFS or OS.
