Abstract
BackgroundInfections with multidrug-resistant K. pneumoniae is associated with high morbidity and mortality especially among critically ill patients. This was the main principle to conduct a detailed study about this organism, its resistance pattern, and type of its resistance genesSubjects and methodsA cross-sectional study was carried out in a pediatric intensive care unit on patients with age range from 1 month to 12 years over a period of 1 year with positive K. pneumoniae using standard microbiological culture and antibiogram sensitivity testing. All collected samples were processed using multiplex PCR technique to identify the most relevant resistant genes.ResultsForty-four patients had 54 positive cultures for K. pneumoniae, out of which 17 patients (38.6%) passed away. The most prevalent-resistant gene was New Delhi metallo-beta lactamase (NDM) gene (65.4%) followed by cefotaximase (CTX-M) gene (57.7%). Extensively drug-resistant K. pneumoniae was detected in (15.9%) of the results and was proved to be independent risk factor increasing mortality odds 139 folds.ConclusionThe evolution of resistance of Klebsiella pneumoniae was proved to be associated with a high mortality rate. Continuous widespread surveillance of Klebsiella pathogen focusing on identification of resistance genes and antibiotic resistance pattern is highly recommended.
