Mucosal Bacterial Immunotherapy in Solid Organ Recipients with Recurrent Respiratory Tract Infections: Case Report

Bacterial infections are the most frequent infectious complications among solid organ recipients. These complications are associated with a high morbidity and mortality, despite recent advances in antimicrobial prophylaxis in the transplant setting. New therapeutic modalities are warranted. We present here a retrospective study based on medical records review of 2 solid organ recipients that were treated with mucosal bacterial immunotherapy because of recurrent bacterial respiratory infections long time after transplantation. A successful decrease of the frequency of bacterial respiratory infections during a period of up to 8 years was observed in one of the patients. We suggest that clinical trials in this field are warranted.
