The
prevalence of
antibiotic resistance is higher in
patients undergoing
renal replacement therapy (RRT) than in
patients who did not undergo RRT. We investigated the presence of KP (
Klebsiella pneumoniae) in
patients who underwent RRT. All data were collected retrospectively by accessing
patient medical records from 2004 to 2011 for the
culture results of all
patients who were positive for KP. We grouped the
patients by the presence of extended-spectrum
beta-lactamase (ESBL) into a KP ESBL(-) group (KP[-]) and a KP ESBL(+) group (KP[+]). In total, 292
patients (23.1%) were in the KP(+) group, and 974
patients (76.9%) were in the KP(-) group. A greater percentage of KP(+) was found in
patients who underwent RRT (7.5%) than in
patients who did not undergo RRT (3.2%) (OR, 2.479; 95% CI,1.412-4.352). A Cox's
hazard proportional model
analysis was performed, and for
patients with
pneumonia, the
risk of KP(+) was 0.663 times higher in
patients who had lower
albumin levels, 2.796 times higher in
patients who had an inserted Levin tube, and 4.551 times higher in
patients who underwent RRT. In conclusion, RRT can be a
risk factor for KP(+) in
patients with
pneumonia.
