Study Motivation: After assessing electronic databases of medical scientific literature, we have observed that the interrelation between urinary tract infections (UTIs) and chronic kidney disease (CKD) is poorly studied, especially when UTIs are caused by Klebsiella pneumoniae (K. pneumoniae). Materials and methods: K. pneumoniae was isolated in 14 urine samples from patients with CKD addmited in the Nephrology Department of the County Emergency Clinical Hospital Craiova. The isolated strains were statistically analyzed in the correlation with the different clinical and functional parameters (age, gender, CKD stage, comorbidities, biochemical parameters-serum urea, creatinine, uric acid and blood electrolytes). The degree of K. pneumoniae susceptibility to antibiotics from different pharmacodynamic classes was assessed. Results: UTIs with K. pneumoniae in patients with CKD in the investigated period represented 0.51% from the total admissions in the clinic and 32.60% from cases of UTI. Eleven patients with this type of infection (78.56%) were in stage 4 and 5 CKD, and from them 4 also had diabetes mellitus type 2 (28.57%). We observed an increased level for serum creatinine (100%), blood urea (85.71%), and serum uric acid (45.45%). Two patients died after installation of cardiovascular changes in CKD, at advanced ages and in the presence of urinary infection. Multiple drug resistance occurred in 6 strains of K. pneumoniae correlated with the degree of kidney failure, advanced age, male gender, and diabetes mellitus. Conclusions: UTI with K. pneumoniae in patients with CKD is the second cause of urinary infection which raises problems of unfavorable evolution of CKD and also the recurrence of UTI with multiple drug resistance in CKD, which may lead to pharmacotherapeutical problems.
