Engraftment syndrome following hematopoietic stem cell transplant: A review of the literature

Abstract

Engraftment syndrome (ES) is a poorly understood condition which continues to present a significant cause of morbidity following haematopoietic stem cell transplantation (HSCT). Yet a standard approach to diagnosis and treatment of ES remains elusive and has the potential to impact patient outcomes. A literature search was performed using the databases ProQuest Health, PubMed, Medline and Embase. Included studies were published in English from 2001-2019 that reported on engraftment syndrome following HSCT. Articles were organized by study design, ES diagnostic criteria, symptom classification and treatment. The review consolidated an array of literature relating to all types of HSCT. Timing of ES onset, risk factors and outcomes were compared within the literature. Signs and symptoms of reported ES were collated to establish a concise set of diagnostic criteria that can provide rapid recognition. The use of a standard approach to ES diagnosis has the potential to improve patient outcomes and provide a uniform approach to future research.
