JAIMES-VELEZ, AM.  and  SOLIS-AYALA, E.. Previous administration of antibiotic as factor related to urinary infection due to E. coli producers of ESBL of community origin in diabetic patients. Med. interna Méx. [online]. 2017, vol.33, n.5, pp.605-611. ISSN 0186-4866.


Urinary tract infections caused by gram-negative bacilli producers of extended-spectrum beta-lactamases (ESBL) are a global public health problem.


An analytical, cross-sectional, pilot study was carried out in Nuevo Sanatorio Durango, Mexico City, in which the cases of urinary tract infection in diabetic patients were reviewed. Two groups were compared depending on the result of the urinary culture. Data were collected taking into account the antecedent of antibiotic treatment, glycosylated hemoglobin (Hb1Ac), history of hospitalization, history of urinary catheter (Foley catheter) and diagnosis of chronic kidney disease.


There were included 103 patients, divided according to the result of the urinary culture: E. coli (n = 49) and E. coli ESBL (n = 54). We found a greater association with ESBL-producing urinary tract infections in individuals aged 68 ± 14.04 years. We calculated odds ratios for each of the items, finding a statistically significant association by means of X2 test (p < 0.05), calculating an OR of 10.2 with the antecedent of antibiotic use and a OR of 2.97 with the diagnosis of chronic kidney disease, when there was isolation of E. coli producing ESBL.


There is an association between the use of antibiotic treatment and the presence of chronic kidney disease with E. coli ESBL isolation in community-acquired infections in diabetic patients.
