Exacerbation of chronic renal failure because of inhaled tobramycin in a lung transplant patient

Abstract

61-year-old man, with a history of years of unknown etiology bronchiectasis, with chronic bronchial infection by Burkholderia multivorans, who received treatment with a double lung transplant on 08/20/2020. Persistent positive cultures of Burkholderia multivorans after transplant in respiratory samples was observed, and treatment with inhaled tobramycin 300 mg/12 hours was started. One month after treatment, a significant worsening of renal function was observed, which was already altered, and toxic levels of tobramycin were measured in blood samples 12 hours after the last inhaled administration. After stopping treatment, kidney function returned to its baseline values.
