Engraftment syndrome (ES) is a complication of hematopoietic stem cell transplantation characterized by fever, rash, and non-cardiogenic pulmonary edema. Acute kidney injury (AKI) has been recognized but is considered a minor criterion in one and excluded another definition of ES. We have noted a high incidence of AKI in patients with immunoglobulin light-chain amyloidosis (AL) undergoing autologous stem cell transplant (ASCT) around the time of leukocyte engraftment. This study was conducted to further investigate the relationship between AKI and ES. Data were collected from 377 AL patients who underwent ASCT from 7/1997 to 10/2009. Patients who experienced an elevation of serum creatinine >0.5 mg/dL within 4 days of leukocyte engraftment and anyone who presented with signs associated with ES regardless of renal manifestations were included. Forty-one patients met criteria. Twelve were excluded for positive cultures (10), acute interstitial nephritis (1), and acute cellular rejection (1). In addition to AKI (93.1%), patients also exhibit fever (82.7%), hypotension (51.7%), rash (48.2%), edema (93.1%), diarrhea (69.0%), conjunctival hemorrhage (31.0%), pulmonary edema (31.0%), pulmonary hemorrhage (13.8%), and transient encephalopathy (17.2%). Patient with pulmonary involvement were more likely to require dialysis but was not statistically significant. AKI was very common during leukocyte engraftment in AL patients. While infectious etiology accounted for some of the AKI, most appeared to be associated with ES. After infection is ruled out, ES should be considered in the differential diagnosis when evaluating AKI in this population.
