Three-day therapy with cephalexin for lower urinary tract infections in children
Insights
A 3-day course of cephalexin effectively treats acute lower urinary tract infections in children, offering a viable alternative to longer nitrofurantoin treatments. This approach shows comparable cure rates and low relapse incidence.
Area of Science:
- Pediatrics
- Infectious Diseases
- Pharmacology
Background:
- Acute lower urinary tract infections (LUTIs) are common in children.
- Standard treatment durations for pediatric LUTIs can be lengthy.
- Identifying shorter, effective antibiotic regimens is crucial for improving adherence and reducing potential side effects.
Purpose of the Study:
- To compare the effectiveness of a 3-day course of cephalexin with a 10-day course of nitrofurantoin for treating acute lower urinary tract infections in children.
- To evaluate immediate cure rates, relapse rates, and reinfection rates between the two treatment groups.
- To assess the safety and tolerability of both antibiotic regimens.
Main Methods:
- A prospective study involving children diagnosed with acute lower urinary tract infections.
- Participants were randomized to receive either a 3-day course of cephalexin (25-50 mg/kg/day) or a 10-day course of nitrofurantoin (3-4 mg/kg/day).
- Outcomes assessed included immediate cure, relapses, reinfections, and adverse events over a mean follow-up of 7-8 months.
Main Results:
- Immediate cure rates were high for both groups: 90% for cephalexin and 96% for nitrofurantoin.
- Relapse rates were low, with 2 cases in the cephalexin group and 1 in the nitrofurantoin group.
- Reinfection rates during follow-up were comparable, with 2 cases in the cephalexin group and 4 in the nitrofurantoin group.
- No significant side effects were reported for either treatment.
Conclusions:
- A 3-day course of cephalexin is an effective and well-tolerated treatment for acute lower urinary tract infections in children.
- Cephalexin offers a reasonable alternative to standard nitrofurantoin therapy, particularly when shorter treatment durations are preferred or other medications are less tolerated.
- The study supports the use of shorter antibiotic courses for pediatric LUTIs, demonstrating comparable efficacy and safety profiles.
Abstract:
In a prospective study of children with an acute infection of the lower urinary tract, the effectiveness of a 3-day course of cephalexin, 25-50 mg/kg body weight and day was compared with that of a 10-day course of nitrofurantoin, 3-4 mg/kg/day. 19 children were allotted to treatment with cephalexin and 24 were treated with nitrofurantoin. The immediate cure rates were 90% and 96%, respectively. Two relapses were noted in the cephalexin group and 1 in the nitrofurantoin group. During a mean follow-up period of 7-8 months 2 of the cephalexin treated patients and 4 patients treated with nitrofurantoin had a reinfection. No side effects were noted in either of the treatment groups. The results suggest that treatment with cephalexin for 3 days is a reasonable alternative in children with an acute lower urinary tract infection when commonly used medications for one reason or another are less well tolerated.
