AI Article Synopsis
- There is a pressing need for better biomarkers to assess chronic graft-versus-host disease (cGvHD), which is a serious risk for patients after hematopoietic stem cell transplantation.
- This review aims to identify new potential biomarkers for cGvHD beyond the already accepted ones, focusing on various sources like cellular markers, alloantibodies, glycans, and microbiome factors.
- While no validated biomarkers for cGvHD are currently available for clinical use, promising areas such as epigenetic changes and microbiome influences indicate potential for future research and development of treatment strategies.
Article Abstract
Prognostic, diagnostic or predictive biomarkers are urgently needed for assessment of chronic graft-versus-host disease (cGvHD), a major risk for patients undergoing allogeneic hematopoietic stem cell transplantation. The main goal of this review generated within the COST Action EUROGRAFT "Integrated European Network on Chronic Graft Versus Host Disease" was to identify potential novel biomarkers for cGvHD besides the widely accepted molecular and cellular biomarkers. Thus, the focus was on cellular biomarkers, alloantibodies, glycomics, endothelial derived particles, extracellular vesicles, microbiome, epigenetic and neurologic changes in cGvHD patients. Both host-reactive antibodies in general, and particularly alloantibodies have been associated with cGvHD and require further consideration. Glycans attached to IgG modulate its activity and represent a promising predictive and/or stratification biomarker for cGVHD. Furthermore, epigenetic changes such as microRNAs and DNA methylation represent potential biomarkers for monitoring cGvHD patients and novel targets for developing new treatment approaches. Finally, the microbiome likely affects the pathophysiology of cGvHD; bacterial strains as well as microbial metabolites could display potential biomarkers for dysbiosis and risk for the development of cGvHD. In summary, although there are no validated biomarkers currently available for clinical use to better inform on the diagnosis, prognosis or prediction of outcome for cGvHD, many novel sources of potential markers have shown promise and warrant further investigation using well characterized, multi-center patient cohorts.

Comparative retrospective analysis of cord blood transplantation with ATG-containing conditioning regimens and haploidentical stem cell transplantation: similar survival outcomes with reduced incidence of GVHD.

Background: Cord blood (CB) is widely used in treating haematologic disorders due to its broad availability, tolerance to significant histocompatibility antigen disparities, and low incidence of chronic graft-versus-host disease (cGVHD). The cord blood transplantation (CBT) with anti-thymocyte globulin (ATG)-containing conditioning regimens shows promise in this regard.
Methods: We conducted a retrospective review of data from patients who underwent CBT at our centre from August 2003 to December 2022.

Systemic administration of Janus kinase (JAK) inhibitors is effective in treating chronic graft-versus-host disease (cGVHD) but is associated with side effects. Topical drug administration effectively minimizes side effects. We aimed to investigate potential trends of the efficacy of topical delgocitinib administration in a mouse model.

Bronchiolitis obliterans (BO) is a disease characterized by airway obstruction and fibrosis that can occur in all age groups. Bronchiolitis obliterans syndrome (BOS) is a clinical manifestation of BO in patients who have undergone lung transplantation or hematopoietic stem cell transplantation. Persistent inflammation and fibrosis of small airways make the disease irreversible, eventually leading to lung failure.

Background: Bronchiolitis obliterans syndrome (BOS) is one of the most devastating outcomes of chronic graft-versus-host disease (cGVHD) after allogeneic hematopoietic stem cell transplantation (allo-HSCT). This remains an area of unmet clinical need for optimal therapy for BOS patients partly due to the limited understanding of pathogenic mechanisms.
Methods: We collected blood samples from 22 patients with cGVHD and 11 patients without cGVHD following allo-HSCT.

Chronic graft versus host disease (cGVHD), occurs in approximately one in five pediatric allogeneic HCT patients and is a leading cause of late morbidity and mortality. Late effects of HCT may lead to long-term chronic health conditions and shortened life expectancy. In addition to direct physiological challenges from cGVHD and other late-effects, numerous patient-important outcomes impact the quality of life (QOL) of patients and their families.
