<b>Conclusions:</b> IL6 may contribute to the risk stratification of patients at major risk for aGvHD and TRM, potentially providing a window for additional prophylactic or preemptive strategies to improve the quality of life in the early post-transplant phase and the outcome of allo-HSCT.
Acute graft-versus-host disease (GVHD) is a primary T-cell-mediated complication of allogeneic hematopoietic stem cell transplantation (HSCT), occurring when donor-derived T cells are stimulated by host antigen-presenting cells (APCs), enhanced by proinflammatory cytokines such as interleukin (IL)-1, IL-6, IL-8, and tumor necrosis factor (TNF)-alpha.

Acute GvHD grades II-IV occurred in 27 of 46 (59%) recipients with a CD31 codon 125 leucine / valine heterozygous donor compared to nine of 39 (23%) recipients with a CD31 codon 125 homozygous donor (P=0.0019, relative-risk 2.45, 95% confidence interval 1.3-4.5).
Acute graft-versus-host disease (GVHD), a major complication of allogeneic stem cell transplantation, involves cytotoxic soluble and cellular effectors that selectively induce apoptosis in normally apoptosis-resistant, cytokeratin 15 (K15)-expressing epithelial stem cells residing at the tips of rete ridges of human epidermis and in analogous rete-like prominences (RLPs) of murine dorsal lingual epithelium.
Acute GVHD was positively associated with HLA-A10 (P = 0.0007), HLA-A26 (P = 0.002), B55 (P = 0.001), DRB1*15 (P = 0.0211) and DQB1*05 (P = 0.038), while HLA-B16 (P = 0.0333) was more frequent in patients without acute GVHD.

Acute GVHD (aGVHD) has been diagnosed by clinical manifestations, laboratory data and pathological effects until now, but recently the discovery of specific biomarkers such as suppression of tumorigenicity 2 (ST2), elafin and regenerating islet-derived 3α (REG3α) is challenging this approach.
CD31 is a candidate human mHag relevant to acute GVHD, but reports disagree about its level of significance, the role of HLA restriction, and the relative importance of different polymorphic codons within the molecule.
HSP70-hom gene polymorphism in allogeneic hematopoietic stem-cell transplant recipients correlates with the development of acute graft-versus-host disease.
HLA-DPB1 allele mismatches were significantly associated with an increased incidence of acute graft-versus-host disease (aGvHD) and worse overall survival (OS).
MBL levels <400 ng/ml were associated with increased susceptibility to fungal pneumonia (7/12 vs 35/111; P=0.04, adjusted P=0.002), HSV/VZV (7/12 vs 26/111; P=0.03), CMV reactivation and acute GVHD.Donor genotypes had no influence.

TGF-beta1 seems to be an additional regulator of donor engraftment; its low levels probably being one of the factors contributing to the development of acute GVHD.
IL-10 is made by a variety of donor and host cells, but the functional relevance of its source and its role in the biology of acute GVHD are not well understood.
MiR-34a expression level was higher in severe aGVHD compared with non-aGVHD subjects or non-transplanted patients, and significantly related to apoptotic cell numbers across the three groups of FA patients.
