Study summary

Antimicrobial treatment of asymptomatic bacteriuria (AB) in kidney transplant recipients (KTR) is controversial. The investigators performed a comparative, parallel-group, randomized, open-label study to assess, in a real clinical setting, the feasibility of and benefit derived from systematic search and antimicrobial treatment of all episodes of AB.

Read the detailed description

All patients undergoing KT between January 2011 and December 2013 in a tertiary-care center with an active transplantation program were systematically searched for AB within the first 2 years after transplantation on a regular basis. During the first 2 months after transplantation all episodes of AB were treated. Thereafter, patients were assigned, according to a computer-generated randomization sequence, to group A (systematic antimicrobial treatment of all episodes of AB) or group B (no treatment). Treatment was chosen according to the results of the urine culture.

Study arms

  • Experimental
    A: Antibiotic adjusted to antibiogram

    A course of 3-14 days of antimicrobial treatment, according to the antibiogram results, will be prescribed for every episode of asymptomatic bacteriuria beyond 2 months after transplantation and during the first 2 years after transplantation

    Other: Antibiotic adjusted to antibiogram

  • No intervention
    B: no treatment

    No treatment of any episode of asymptomatic bacteriuria beyond 2 months after transplantation in kidney transplant recipients.

Interventions

  • OtherAntibiotic adjusted to antibiogram

    A course of 3-14 days of antimicrobial treatment, according to the antibiogram results, will be prescribed for every episode of asymptomatic bacteriuria during the first 2 years after transplantation.

What researchers measure

Primary outcomes

  1. Incidence of Pyelonephritis

    The number of patients that develope pyelonephritis in the first 2 years after transplantation in each group, divided by the number of patients allocated in each group at randomization.

    Time frame: 2 years after transplantation

Secondary outcomes

  1. Incidence of lower tract urinary infection

    The number of patients that develope lower tract urinary infection in the first 2 years after transplantation in each group, divided by the number of patients allocated in each group at randomization.

    Time frame: 2 years after transplantation

  2. Incidence of Clostridium difficile infection

    The number of patients that develope Clostridium difficile infection in the first 2 years after transplantation in each group, divided by the number of patients allocated in each group at randomization.

    Time frame: 2 years after transplantation

  3. Incidence of multidrug resistant bacteria colonization/infection

    The number of patients that develope multidrug resistant bacteria colonization/infection in the first 2 years after transplantation in each group, divided by the number of patients allocated in each group at randomization.

    Time frame: 2 years after transplantation

  4. Long-term graft function

    Long-term graft function measured by average serum creatinine at several points until the end of follow-up.

    Time frame: At 1 year and 2 years after transplantation

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Feb 26, 2015, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
