Bladder and kidney infections (urinary tract infections - UTI) are common in children. Bladder infections cause pain on passing urine and frequency of urination. Some children keep getting repeat bouts. Standard courses of antibiotics (7-10 days) are used to clear the infection. Shorter courses may reduce adverse effects and costs, but there has been concern that they might reduce the chances of clearing the infection and increase the risk of recurrence. A review of studies found that short courses of antibiotics (2-4 days) used for bladder infections are as effective as standard courses at clearing UTI, with no increase in recurrence.

The optimal duration of oral antibiotic therapy for urinary tract infection (UTI) in children has not been determined. A number of studies have compared single dose therapy to standard therapy for UTI, with mixed results. A course of antibiotics longer than a single dose but shorter than the usual 7-10 days might decrease the relapse rate and still provide some of the benefits of a shortened course of antibiotics.
Ciljevi
The objective of this review was to assess the benefits and harms of short-course (2-4 days) compared to standard duration (7-14 days) oral antibiotic treatment for acute UTI in children.
Metode pretraživanja
We searched the Cochrane Central Register of Controlled Trials (CENTRAL in The Cochrane Library) MEDLINE (from1966) and EMBASE (from 1988) without language restriction.
Kriteriji odabira
Randomised and quasi-randomised controlled trials comparing short-term (2-4 days) with standard (7-14 days) oral antibiotic therapy were selected if they studied children aged three months to 18 years with culture proven UTI.
Prikupljanje podataka i obrada
Two authors independently assessed study quality and extracted data. Statistical analyses were performed using the random effects model and the results expressed as relative risk (RR) with 95% confidence intervals (95% CI).
Glavni rezultati
Ten studies were identified in which 652 children with lower tract UTI were evaluated. There was no significant difference in the frequency of positive urine cultures between the short (2-4 days) and standard duration oral antibiotic therapy (7-14 days) for UTI in children at 0-10 days after treatment (eight studies: RR 1.06; 95% CI 0.64 to 1.76) and at one to 15 months after treatment (10 studies: RR 0.95; 95% CI 0.70 to 1.29). There was no significant difference between short and standard duration therapy in the development of resistant organisms in UTI at the end of treatment (one study: RR 0.57, 95% CI 0.32 to 1.01) or in recurrent UTI (three studies: RR 0.39, 95% CI 0.12 to 1.29).
Zaključak autora
A 2-4 day course of oral antibiotics appears to be as effective as 7-14 days in eradicating lower tract UTI in children.
