PEREZ VALIENTE, Dayana et al. Renal alterations in hematopoietic progenitor cell transplantation. Rev cubana med [online]. 2005, vol.44, n.3-4. ISSN 0034-7523.

A retrospective and descriptive study was conducted among 97 patients that underwent hematopoietic progenitor cell transplantation (HPCT) between 1985 and 2004 to evaluate their renal alterations. An incidence of this complication of 27.5 % was observed in the analysed sample. The most frequent renal alterations were acute renal dysfunction and failure. (51.6 and 22.5 %, respectively). During the first 120 days of the transplantation, there was a predominance of acute renal dysfunction, whereas in the period of more than 120 days there was a prevalence of radiogenic nephritis. The prevailing causes were the multifactorial (54.2 %) and nephrotoxicity due to cyclosporin A (17.1 %): up to 30 days, the multifactorial (72.7 %); between 31 and 120 days, the nephrotoxicity due to cyclosporin A (71.4 %); and in the period over 120 days, the radiations (50 %). More alterations were observed in the allogenous transplant recipients (61.5 %) than in the autologous transplant recipients (15.4 %). Among those who underwent CMT + RT as a conditioning regime (30.8 %) there were also more alterations than among those who received only CMT (11.7 %). The application in the conditioning regime of the unique doses of radiotherapy was correlated with the appearance of radiogenic nephritis.
