Patients with cystitis/urethritis present a lower incidence of urinary tract symptoms: urgency, dysuria and frequency, which are caused by inflammation of the mucosal epithelium where the urinary bacteria adhere. Although it may frequently be self-limiting and easily treated with antibiotics, it frequently does not completely resolve and may cause recurrences despite the use of antibiotics. Uncomplicated acute UTI is one of the most common bacterial infections responsible for significant morbidity as well as elevated health care costs. However, in the second decade of life it predominates in girls at a ratio of 4:1. Generally, the risk of a UTI during the first decade of life is 1% for males and 3% for females. Symptomatic infection occurs in 1/1,000 newborns and infants 1 month of age, being most common in males (ratio 2.7:0.7) up to the first year of life.

The frequency of a urinary tract infection (UTI) may vary according to the age and gender of the patient. Conclusions: Frequently prescribed empirical agents for uncomplicated urinary tract infection demonstrate lowered in vitro susceptibilities when tested against recent clinical isolates. faecalis) and 49.9 for Enterococcus faecium (E. mirabilis and Enterobacter spp., 92.5 for Enterococcus faecalis (E. The resistance to trimetoprim/sulfametoxazol (%) was 73.7, 62.2, 100, 52, and 50, respectively, for E. aeruginosa) (34, 7.5%), Proteus mirabilis (P. pneumoniae) (40, 8.7%), Pseudomonas aeruginosa (P. Results: The most frequently isolated urinary pathogens were as follows: Escherichia coli (E. All isolates were identified and the in vitro activities of antimicrobials were determined. Midstream and catheter urine specimens were collected. Patients who had had symptoms for >7 days and those who had had previous episodes of urinary tract infection, received antibiotics or other complicated factors were excluded. Methods: A total of 457 consecutive children attending the emergency room at the Hospital Infantil de México Federico Gómez with symptoms of uncomplicated lower urinary tract infection were eligible for inclusion. The goal of this study was to determine antibiotic susceptibility to commonly used agents for urinary tract infection against recent urinary isolates. As a result, appropriate use of antimicrobial agents, however, increases antibiotic resistance and complicates its treatment due to increased patient morbidity, costs, rates of hospitalization, and use of broader-spectrum antibiotics. faecium.Ĭonclusiones: Los antimicrobianos frecuentemente prescritos para el tratamiento empírico de la infección del tracto urinario no complicada demuestran resistencia importante o baja susceptibilidad cuando se les probó frente a las cepas aisladas.īackground: Urinary tract infection in children is well recognized as a cause of acute morbidity and chronic medical conditions.

La orina fue tomada a la mitad del chorro o por cateterismo, y se realizó la identificación y la susceptibilidad antimicrobiana. Métodos: Se incluyeron en el estudio 457 niños que asistieron a la consulta externa y a urgencias del Hospital Infantil de México Federico Gómez, con síntomas de infección del tracto urinario baja no complicada. El propósito de este estudio fue determinar la susceptibilidad antimicrobiana de los uropatógenos aislados en niños. Sin embargo, la resistencia creciente complica su tratamiento ya que aumenta la morbilidad, los costos, la estancia hospitalaria y el uso de fármacos de mayor espectro antimicrobiano. Introducción: La infección del tracto urinario en los niños es reconocida como una causa de morbilidad y de condiciones médicas crónicas, por lo que resulta indispensable conocer con claridad la patogénesis de esta enfermedad.
