Aim To investigate the efficacy and safety of home‐treatment with oral piv‐mecillinam or amoxicillin‐clavulanate in children with acute pyelonephritis. Methods Children aged over 6 months diagnosed with culture confirmed pyelonephritis at Danish Paediatric Departments were home‐treated with piv‐mecillinam (tablets) or amoxicillin‐clavulanate (liquid or tablets). Follow‐up was performed by phone (second treatment day) and clinical review of the patients in the hospital (day three). Results Four hundred eighteen children were included. In total, 333/418 (80%) responded well to the initial oral antibiotic treatment. 85/418 (20%) were changed to another treatment of these 47/418 (11%) to a second‐line oral antibiotic and 38/418 (9%) to intravenous antibiotics due to insufficient clinical improvement or bacterial resistance. Bacterial resistance was similar for piv‐mecillinam and amoxicillin‐clavulanate: 4/74 (5%) versus 33/333 (10%) ( p = 0.22). Insufficient clinical improvement, despite no resistance, primarily occurred in children treated with piv‐mecillinam: 16/74 (22%) versus 28/344 (8%) ( p < 0.001), and predominantly occurred in piv‐mecillinam treated children <5 years: 7/20 (35%) versus 9/54 (17%) ( p < 0.05), potentially because of problems with piv‐mecillinam tablets. In the study population no cases of death or septicemia developed after start of initial oral treatment. Conclusion A home‐treatment regime for pyelonephritis in children >6 months is safe; however, during treatment, clinical re‐evaluation is required as in 20% of cases a change in treatment was necessary.
