Clinical Significance of Gastrointestinal Carriage of Klebsiella Pneumoniae-Producing Extended-Spectrum Beta-Lactamases in Kidney Graft Recipients.

The burden of Klebsiella pneumoniae (KP) producing extended-spectrum beta-lactamases (ESBL+) urinary tract infections (UTIs) is a growing problem after kidney transplantation (KTX). The study was aimed at evaluating the incidence of KP ESBL+ gut colonization in KTX recipients and its correlation with clinical outcomes with special regard to UTIs. The study included all KTX patients hospitalized in our department between January 2014 and December 2016.

Successful Treatment of Urinary Tract Infection in Kidney Transplant Recipients Caused by Multiresistant Klebsiella pneumoniae Producing New Delhi Metallo-Beta-Lactamase (NDM-1) With Strains Genotyping.

Background: Klebsiella pneumoniae New Delhi metallo-beta-lactamase-1 (NDM-1) strains have recently become a new threat in kidney transplant recipients due to the strains' resistance to almost all antibiotics, including carbapenems.

Methods: We present a case series of 3 patients with urinary tract infections (UTIs) caused by multiresistant K pneumoniae NDM-1 strains who were treated with the same protocol. Genotyping sequencing with pulsed-field gel electrophoresis was performed in all cases.

Epidemiological and Drug-Resistance Types of Methicillin-Resistant Staphylococcus Aureus Strains Isolated From Surgical and Transplantation Ward Patients During 2010 to 2011.

Background: The increasing prevalence of multi-drug-resistant methicillin-resistant Staphylococcus aureus (MRSA) is a substantial problem in hospitals worldwide, especially in wards with immunocompromised patients undergoing organ transplant. Epidemiological characteristics and antibiotic susceptibility profiles of hospital-acquired (HA) MRSA strains isolated from surgical/transplantation ward patients were studied.

Methods: We analyzed 26 HA-MRSA strains isolated from 22 patients hospitalized at 3 different surgical and transplantation wards at a Warsaw clinical hospital during 2010 to 2011.

Drug Susceptibility Assessment in Stenotrophomonas Maltophilia Strains Isolated From the Blood of Organ Transplantation Recipients in a Warsaw Teaching Hospital During 2011 to 2014.

Background: Blood infections with multidrug-resistant Gram-negative carbapenem-resistant bacilli are particularly dangerous and challenging to treat in organ transplant recipients. Resistance to carbapenems may be acquired, for example, in Enterobacteriaceae, Pseudomonas, or Acinetobacter spp. or innate, for example, in Stenotrophomonas maltophilia.

Blood infections in patients treated at transplantation wards of a clinical hospital in Warsaw.

Establishment of the etiology in blood infection is always advisable. The purpose of this study was to evaluate the proportion of different bacterial species, including aerobic and anaerobic bacteria in blood cultures of patients hospitalized in transplantation wards of a large clinical hospital between 2010 and 2012. A total of 1994 blood samples from patients who were treated at one of two transplantation wards of a large hospital in Warsaw were analyzed using an automated blood culture system, BacT/ALERT (bioMerieux, France).
