Incidence and impact of community respiratory viral infections in post-transplant cyclophosphamide-based graft-versus-host disease prophylaxis and haploidentical stem cell transplantation.

Br J Haematol 2021 Jun 14. Epub 2021 Jun 14.

Department of Medicine, City of Hope, Duarte, CA, USA.

Community respiratory viral infections (CRVIs) are associated with pulmonary function impairment, alloimmune lung syndromes and inferior survival in human leucocyte antigen (HLA)-matched allogeneic haematopoietic stem cell transplant (HCT) recipients. Although the incidence of viral infections in HLA-haploidentical HCT recipients who receive post-transplant cyclophosphamide (PTCy)-based graft-versus-host disease (GVHD) prophylaxis is reportedly increased, there are insufficient data describing the incidence of CRVIs and the impact of donor source and PTCy on transplant outcomes. Analysing patients receiving their first HCT between 2012 and 2017 for acute myeloid leukaemia, acute lymphoblastic leukaemia and myelodysplastic syndromes, we describe comparative outcomes between matched sibling transplants receiving either calcineurin-based GVHD prophylaxis (SibCNI, N = 1605) or PTCy (SibCy, N = 403), and related haploidentical transplants receiving PTCy (HaploCy, N = 757).

NLRP3 Inflammasome Assembly in Neutrophils Is Supported by PAD4 and Promotes NETosis Under Sterile Conditions.

Front Immunol 2021 28;12:683803. Epub 2021 May 28.

Program in Cellular and Molecular Medicine, Boston Children's Hospital, Boston, MA, United States.

Neutrophil extracellular trap formation (NETosis) and the NLR family pyrin domain containing 3 (NLRP3) inflammasome assembly are associated with a similar spectrum of human disorders. While NETosis is known to be regulated by peptidylarginine deiminase 4 (PAD4), the role of the NLRP3 inflammasome in NETosis was not addressed. Here, we establish that under sterile conditions the cannonical NLRP3 inflammasome participates in NETosis. Read More

The lung microbiome in lung transplantation.

J Heart Lung Transplant 2021 May 7. Epub 2021 May 7.

Division of Pulmonary, Allergy and Critical Care Medicine, Perelman School of Medicine at the University of Pennsylvania, Philadelphia, Pennsylvania; Department of Microbiology, Perelman School of Medicine at the University of Pennsylvania, Philadelphia, Pennsylvania.

Culture-independent study of the lower respiratory tract after lung transplantation has enabled an understanding of the microbiome - that is, the collection of bacteria, fungi, and viruses, and their respective gene complement - in this niche. The lung has unique features as a microbial environment, with balanced entry from the upper respiratory tract, clearance, and local replication. There are many pressures impacting the microbiome after transplantation, including donor allograft factors, recipient host factors such as underlying disease and ongoing exposure to the microbe-rich upper respiratory tract, and transplantation-related immunosuppression, antimicrobials, and postsurgical changes.

Palliative care in lung transplantation.

Ann Palliat Med 2021 Jun 1. Epub 2021 Jun 1.

Division of Thoracic Surgery, The Johns Hopkins Hospital, Baltimore, MD, USA.

The role of palliative care in lung transplantation has grown exponentially in the past two decades. From assisting with evaluating and optimizing candidates for transplant, to playing a crucial role in patients requiring extracorporeal cardiopulmonary life support (ECLS) as a bridge to lung transplant, perioperatively, or even during their first year post-transplant, palliative care has been shown to be an effective if underutilized tool in the armamentarium used to care for lung transplant patients. For patients being considered for primary transplantation and for lung transplant recipients, palliative care can decrease symptom burden and help to lessen the psychological distress experienced by patients and family members.
