[Reccurent Clostridium difficile infection in patient after kidney transplantation on rituximab therapy due to PTLD (Post-Transplant Lymphoprolipherative Disorder). First experience with Fidaxomicin use--case report]. / Nawracajaca infekcja Clostridium difficile u chorego po przeszczepieniu nerki leczonego rytuksymabem z powodu PTLD (Post- Transplant Lymphoprolipherative Disorder). Pierwsze doswiadczenie ze stosowaniem fidaksomycyny--opis przypadku.

Clostridium difficile infection (CDI) is an increasingly problem in everyday clinical practice. The most important risk factor of this infection is antibiotics use. The incidence of Clostridium difficile associated diarrhea (CDAD) in patients after renal transplantation is estimated to be about 6% in the early postoperative period. Due to the applied immunosuppression and frequent infections requiring intensive, broad spectral antibiotics, the later prevalence of CDAD may remain at a similar level. Massive diarrhea caused by Clostridium difficile may lead to fluctuations in immunosuppressive drugs concentration, in renal transplant patients. The authors present a case study of a 23-year old patient after kidney transplantation from deceased donor, with diagnosed polymorphic PTLD (Post-Transplant Lymphoproliferative Disorder). During biological treatment with rituximab in this patient 4 recurrences of CDI were observed. In this article the clinical manifestation of recurrent CDAD are presented. The authors discuss therapeutic procedure with fidaxomicin use, its results and influence on immunosuppressive drugs concentration.
