BackgroundEnd-stage renal disease (ESRD) is a known immunocompromising status that predisposes patients to developing infections. Disease from Listeria monocytogenes may affect any host but tends to be more severe in the immunocompromised.MethodsWe used a large population of patients with ESRD to identify risk factors for listeriosis and mortality. Patients with a diagnosis of Listeria and other risk factors for listeriosis were identified using claims data from the United States Renal Data System database from 2004-2015. Demographic parameters and risk factors associated with Listeria were modeled using logistic regression while association with mortality was assessed with Cox Proportional Hazards modeling.ResultsA diagnosis of Listeria was identified in 291 (0.01%) of a total 1,071,712 patients with ESRD. Cardiovascular disease, connective tissue disease, upper gastrointestinal ulcerative disease, liver disease, diabetes, cancer, and human immunodeficiency virus were all associated with an increased risk of Listeria. Patients with Listeria had an increased risk of death relative to patients without Listeria (adjusted hazard ratio=1.79; 95% confidence interval 1.52-2.10).ConclusionsIncidence of listeriosis in our study population was over 7 times higher than what has been reported for the general population. The independent association of a Listeria diagnosis with increased mortality is also consistent with the disease's high mortality in the general population. Due to limitations with diagnosis, providers should maintain high clinical suspicion for listeriosis when patients with ESRD present with a compatible clinical syndrome. Further prospective study may help precisely quantify the increased risk of listeriosis in patients with ESRD.Published by Elsevier Inc.
