Risk Factors of Graft-Versus-Host Disease in the Iranian Allogeneic Hematopoietic Stem Cell Transplantation: A 10-Year Experience
Background: Graft-versus-host disease (GVHD) is a serious complication associated with allogeneic hematopoietic stem cell transplantation (allo-HSCT). Thus, it is necessary to evaluate the risk factors of GVHD in allo-HSCT. Herein, ..... see more
Decreased Plasma Level of Cytokeratin 20 (KRT20) Is Indicative of the Emergence and Severity of Acute GvHD Irrespective to the Type of Organ Involvement - PubMed
Accurate risk prediction of acute graft versus host disease (aGvHD) is currently an unmet clinical need. This study sought to analyze whether three plasma proteins expressed in a largely skin- ..... see more
Conclusion/Relevance: The discovery cohort (n = 39) revealed that at the time of diagnosis, plasma KRT20 showed a progressive decrease from unaffected individuals to patients with single-, and patients with multi-organ aGvHD. KRT20 was affected by cutaneous (p = 0.0263) and gastrointestinal aGvHD (p = 0.0242) independently and in an additive...
Can transfusion-associated graft-versus-host disease (TA-GvHD) be prevented with leukoreduction alone?
Transfusion-associated graft-versus-host disease (TA-GvHD) is a rare but devastating disease with a very high mortality rate. Because of the high mortality and lack of effective treatments, the current state of ..... see more
Source : https://www.trasci.com/article/S1473-0502(22)00064-7/fulltext
Conclusion/Relevance: “Given that TA-GvHD is driven by contaminating white blood cells, and the fact that the international transfusion community has largely embraced leukoreduction, this raises the question as to whether the quantitative reduction of leukocytes via filtration can itself prevent TA-GvHD, thus allowing hospitals to skip...

Conclusion: Overall, development of new strategies such as RTC and generalisation of in vivo T-cell depletion with ATG and/or PTCy, translate into a decreased incidence of haGVHD. Furthermore, despite a higher incidence of cGVHD in patients with haGVHD compared to aGVHD after day 14, NRM and OS were similar. This suggests that patients with...

Day 4 vs. day 12 G-CSF administration following reduced intensity peripheral blood allogeneic stem cell transplant - PubMed
Compared to day + 4, day + 12 G-CSF initiation following RIC alloHCT had a longer time to neutrophil and platelet engraftment. Day + 12 initiation also resulted in longer ..... see more
Conclusion: Compared to day 4, day 12 G-CSF initiation following RIC alloHCT had a longer time to neutrophil and platelet engraftment. Day 12 initiation also resulted in longer LOS, which while statistically significant, was potentially of limited clinical significance. These findings are hypothesis generating.

Conclusion/Relevance: In the multivariate analysis, young age and Haplo-cord HSCT were favorable factors for HRQoL, while moderate to severe cGVHD was associated with lower HRQoL. These results suggest that for SAA patients, Haplo-cord HSCT could achieve at least comparable efficacy and HRQoL to MRD-HSCT.

Conclusions: LTV prophylaxis delays HCMV infection and HCMV-specific immune reconstitution, therefore immunological and virological monitoring should be implemented post-prophylaxis discontinuation. The potential effect of LTV prophylaxis in reducing chronic GvHD should be evaluated by prospective studies.
