title: Successful treatment of ctx-m ESBL producing Escherichia coli relapsing pyelonephritis with long term pivmecillinam.
abstract: Oral therapy options for pyelonephritis caused by ESBL producing E. coli are limited. We describe a woman with relapsing pyelonephritis due to a CTX-M ESBL E. coli who was cured with a prolonged course of pivmecillinam. This suggests pivmecillinam may be effective treatment for selected patients with pyelonephritis with these organisms.
