OBJECTIVE. Effective treatment of acute lobar nephronia (ALN ) can prevent its progression to renal abscess. The goal of this prospective study was to compare the treatment efficacy for pediatric patients who had ALN with a 3- vs 2-week intravenous plus oral antimicrobial-therapy regimen.METHODS. Patients who were suspected of having an upper urinary tract infection underwent a systematic scheme of ultrasonographic and computed tomographic(CT) evaluation for ALN diagnosis. Patients with positive CT findings were enrolled and randomly allocated with serial entry for either a total 2-week or a 3-week antibiotic treatment regimen. Antibiotics were changed from an intravenous form to an oral form 2 to 3 days after defervescence of fever. Follow-up clinical evaluations and urine-culture analyses were performed 3 to 7 days after cessation of antibiotic treatment. Patients with persistent infection or relapse were considered as treatment failures. RESULTS.A total of 80 patients with ALN were enrolled. Forty-one patients were treated with a 2-week antimicrobial protocol, and the other 39 patients were treated with a 3-week course. Seven treatment failures, 1 persistent infection, and 6 infection relapses were identified, all of which were in the 2-week treatment group. Prolonged fever before admission and positive Escherichia coli growth (105 colony-forming units per mL) in urine culture were noted as risk factors for treatment failure. All treatment failures were managed successfully with an additional 10-day antibiotic course. CONCLUSION.A total of 3 weeks of intravenous and oral antibiotic therapy tailored to the pathogen noted in cultures should be the treatment of choice for pediatric patients with ALN.
