Erythema migrans in solid-organ transplant recipients.

Six adult solid-organ transplant recipients who had chronic drug-induced immunosuppression and who presented with solitary erythema migrans were treated with antibiotics administered at the same dosage and for the same duration used for the treatment of early, localized Lyme borreliosis in immunocompetent patients. The patients had a smooth course of illness and a favorable outcome but did not develop a measurable borrelial serum antibody response.
