ABSTRACT
BACKGROUND:
Diarrhea is a common symptom among liver transplant (LT) recipients and can result in significant morbidity. The utility of PCR-based multiplex gastrointestinal (GI) pathogen panels in this population is unknown.METHODS:
We assessed incidence, predictors, and outcomes of GI PCR positivity among inpatients who underwent stool pathogen testing with the FilmArray multiplex GI PCR panel at our institution within 1 year following LT from April 2015 to December 2019.RESULTS:
A total of 112 patients were identified. Of these, 14 (12.5%) had a positive PCR for any pathogen. Escherichia coli (n = 9) and Norovirus (n = 5) were the most common pathogens detected. Recipients with a positive PCR were significantly further from LT (median 74.5 vs. 15.5 days, p < .01) and tested earlier during hospitalization (median 1.0 vs. 9.0 days, p < .01). C. difficile was positive in 20.0% of patients with a positive PCR and 11.4% with a negative PCR. CMV viremia was observed in 11.6% of patients, all in the negative PCR group. Following a positive PCR, patients were more likely to have a change in antimicrobial regimen (71.4% vs. 28.6%, p = .02), a shorter length of stay (median 7.5 vs. 17.5 days, p < .01), and a trend toward lower rates of readmission and colonoscopy within 30 days.CONCLUSIONS:
In hospitalized LT recipients with diarrhea, GI PCR pathogen identification was associated with the use of targeted antimicrobial therapy and a shorter length of stay. GI PCR testing should be considered early during admission and later in the post-LT period.Palavras-chave
