Paired oral cGVHD biopsies obtained before (n = 12) and 1 month after treatment (n = 12) with topical dexamethasone (n = 8) or tacrolimus (n = 4) were characterized by immunohistochemistry using a panel of CD1a, CD3, CD4, CD8, CD20, CD31, CD62E, CD103, CD163, c-kit, and FoxP3.
Our results demonstrate that CD19(+)CD21(low) B cells and CD4(+)CD45RA(+)CD31(+) T cells are significantly elevated in patients with newly diagnosed cGVHD.
We evaluated the association of 4 SNPs in ICAM1 (rs5498), PECAM1 (rs668 and rs1131012) and SELL (rs2229569) genes with acute and chronic graft-versus-host disease (GvHD) and those experiencing transplant-related mortality (TRM) within 1 year among 425 allogeneic HCT recipient-donor pairs.
The CD31 noncompatibility showed statistical non-significant relation with aGVHD (G 0-I, and G II-IV) and chronic GVHD (De-novo and chronic on acute) (p = 0.59, p = 0.62, p = 036 and p = 0.83, respectively).
