Occurrence of carbapenemase-producing Klebsiella pneumoniae and Escherichia coli in the European survey of carbapenemase-producing Enterobacteriaceae (EuSCAPE): a prospective, multinational study
Background Gaps in the diagnostic capacity and heterogeneity of national surveillance and reporting standards in Europe make it difficult to contain carbapenemase-producing Enterobacteriaceae. We report the development of a consistent sampling framework and the results of the first structured survey on the occurrence of carbapenemase-producing Klebsiella pneumoniae and Escherichia coli in European hospitals. Methods National expert laboratories recruited hospitals with diagnostic capacities, who collected the first ten carbapenem non-susceptible clinical isolates of K pneumoniae or E coli and ten susceptible same-species comparator isolates and pertinent patient and hospital information. Isolates and data were relayed back to national expert laboratories, which made laboratory-substantiated information available for central analysis. Findings Between Nov 1, 2013, and April 30, 2014, 455 sentinel hospitals in 36 countries submitted 2703 clinical isolates (2301 [85%] Kpneurnoniae and 402 (15%) Ecoli). 850 (37%) of 2301 Kpneumoniae samples and 77 (19%) of 402 Ecoli samples were carbapenemase (KPC, NDM, OXA-48-like, or VIM) producers. The ratio of K pneumoniae to E coli was 11:1.1.3 patients per 10000 hospital admissions had positive clinical specimens. Prevalence differed greatly, with the highest rates in Mediterranean and Balkan countries. Carbapenemase-producing K pneumoniae isolates showed high resistance to last-line antibiotics. Interpretation This initiative shows an encouraging commitment by all participants, and suggests that challenges in the establishment of a continent-wide enhanced sentinel surveillance for carbapenemase-producing Entero-bacteriaeceae can be overcome. Strengthening infection control efforts in hospitals is crucial for controlling spread through local and national health care networks
Epidemic of carbapenem-resistant Klebsiella pneumoniae in Europe is driven by nosocomial spread
Public health interventions to control the current epidemic of
carbapenem-resistant Klebsiella pneumoniae rely on a comprehensive
understanding of its emergence and spread over a wide range of
geographical scales. We analysed the genome sequences and
epidemiological data of >1,700 K. pneumoniae samples isolated from
patients in 244 hospitals in 32 countries during the European Survey of
Carbapenemase-Producing Enterobacteriaceae. We demonstrate that
carbapenemase acquisition is the main cause of carbapenem resistance and
that it occurred across diverse phylogenetic backgrounds. However, 477
of 682 (69.9%) carbapenemase-positive isolates are concentrated in four
clonal lineages, sequence types 11,15,101, 258/512 and their
derivatives. Combined analysis of the genetic and geographic distances
between isolates with different beta-lactam resistance determinants
suggests that the propensity of K. pneumoniae to spread in hospital
environments correlates with the degree of resistance and that
carbapenemase-positive isolates have the highest transmissibility.
Indeed, we found that over half of the hospitals that contributed
carbapenemase-positive isolates probably experienced within-hospital
transmission, and interhospital spread is far more frequent within,
rather than between, countries. Finally, we propose a value of 21 for
the number of single nucleotide polymorphisms that optimizes the
discrimination of hospital clusters and detail the international spread
