Incidence of Viral and Fungal Infectious Complications after utilization of alternative donor sources in hematopoietic cell transplantation (HCT)

AbstractAllogeneic hematopoietic cell transplantation (HCT) remains the only curable option for adult patients with hematologic malignancies. According to guidelines published by the American Society for Transplantation and Cellular Therapy, allogeneic HCT should be offered to all intermediate ‐ and high‐risk patients with acute leukemia. While matched‐related donor (MRD) grafts continue to be the preferred stem cell source for allogeneic HCT, studies comparing MRD grafts to matched‐unrelated donor (MUD) grafts showed comparable outcomes in patients with acute leukemia. Unfortunat ely, for those without a suitable matched‐related graft, the probability of finding a suitable matched‐unrelated donor varies significantly depending on racial and ethnic background. With allogeneic HCT procedures increasing year after year due to the increased availability of suitable donors, e ach of these alternative donor sources merits special clinical considerations, specifically with regards to infections. Infections remain a significant cause of morbidity and mortality after allogeneic transplant, especially in those receiving alternative donor graft. Due to the high‐risk nature a ssociated with these donor grafts, it is important to understand the true risk of developing infectious complications. While there are a multitude of infections that have been described in patients post‐allogeneic HCT, this review seeks to focus on the incidence of cytomegalovirus (CMV) and invasi v...

CONCLUSION: This study found that childhood cancer survivors in New Zealand had a high prevalence of developmental dental abnormalities and it identified potential risk factors related to their cancer treatment. Inequitable access to oral rehabilitation for this patient group argues for a mechanism for consistent improved access to publicly funded dental care across district health boards in New Zealand.

CONCLUSION: DAAs are effective and safe in the treatment of recurrent HCV infection in LT recipients with history of HCC. Relapse to pre- and post-LT DAA therapy is associated with post-transplantation HCC recurrence. PMID: 33033569 [PubMed]

Authors: Singh G, Yoshida EM, Rathi S, Marquez V, Kim P, Erb SR, Salh BS Abstract Hepatocellular carcinoma (HCC) is the third leading cause of cancer-related deaths worldwide. If diagnosed early, curative treatment options such as surgical resection, loco-regional therapies, and liver transplantation are available to patients, increasing their chances of survival and improving their quality of life. Unfortunately, most patients are diagnosed with late stage HCC where only palliative treatment is available. Therefore, biomarkers which could detect HCC early with a high degree of sensitivity and specificity, may play...

Infectious diseases are still a significant cause of morbidity and mortality worldwide. Despite the progress in drug development, the occurrence of microbial resistance is still a significant concern. Alternative therapeutic strategies are required for non-responding or relapsing patients. Chimeric antigen receptor (CAR) T cells has revolutionized cancer immunotherapy, providing a potential therapeutic option for patients who are unresponsive to standard treatments. Recently two CAR T cell therapies, Yescarta® (Kite Pharma/Gilead) and Kymriah® (Novartis) were approved by the FDA for the treatments of certain types ...

In this study they also showed PTX3 localized in NETs formed after neutrophil activation (5). Proteomics analysis revealed that PTX3 forms complexes with two anti-microbial proteins [azurocidin (AZU1) and myeloperoxidase (MPO)] associated to NETs (30). More recently, PTX3 localization in NETs has been confirmed, and the colocalization with AZU1 and MPO has been defined more accurately (31). Further investigation will be needed to understand the involvement of PTX3 interaction with AZU1 and MPO in their antibacterial role during NET formation. Regulation of Complement Activation PTX3 interaction with microorganisms is not...

Allogeneic hematopoietic stem cell transplantation (HSCT) is an effective treatment for hematological malignancies. Graft-versus-host disease (GVHD) is an important cause of graft failure and death. At present, the classic prevention program of GVHD is cyclosporine and calcineurin inhibitor (CNI; i.e. tacrolimus) plus methotrexate (CTX) or mycophenolate mofetil (MMF). However, the incidence of aGVHD is about 30-50%. Furthermore, the classic preventive regimen can also inhibit the graft-versus-leukemia effective (GVL) effect while reducing aGVHD, thereby increasing the recurrence rate, slowing the immune reconstitution, inc...

CONCLUSIONS: The Delphi method was useful for the classification and stratification of risk factors for IFI-FF in patients with onco-haematological diseases. Identifying key risk factors will contribute to a better management of IFI-FF in this group of patients at high or changing risk. PMID: 28198173 [PubMed - as supplied by publisher]
