ABSTRACT

O presente relato apresenta o caso clínico de uma paciente com leucemia promie-locítica aguda tratada com ácido todo-transretinoico (ATRA), que apresentou suspeita de síndrome do ácido transreti-noico (síndrome de ATRA). Com a ocor-rência de leucopenia febril inespecífica, foram associados ao tratamento antimi-crobianos e antifúngicos. A diminuição da função renal, observada inicialmente, contribuiu para a suspeita de síndrome de ATRA, que foi agravada pelos antifúngi-cos. Assim, o uso de ATRA foi suspenso, mas somente 8 dias depois foi caracteriza-da pneumonia e descartada a hipótese de síndrome de ATRA. Nesse contexto, foi discutida a nefrotoxicidade do ATRA e a potencialização desse efeito adverso pelo uso de antifúngicos nefrotóxicos, em par-ticular da anfotericina B, assim como a im-portância do diagnóstico diferencial entre síndrome de ATRA e doença infecciosa.


This is a report of the case of a patient with acute promyelocytic leukemia treated with all trans-retinoic acid (ATRA), who had suspected all-trans retinoic acid syndrome (ATRA syndrome). The nonspecific febrile leukopenia observed justified the association with antimicrobial and antifungal therapy. Signs and symptoms contributed to the sus-picion of ATRA syndrome, and renal func-tion was impaired by the combination with antifungal agents. The decrease in renal function observed initially contributed to the suspicion of ATRA syndrome and was aggravated by antifungals. Thus, the use of ATRA was discontinued. Eight days after the pneumonia characterization, the possibil-ity of ATRA syndrome was dismissed. In this context, ATRA's nephrotoxicity and the syn-ergic adverse effect by the use of nephrotoxic antifungal agents were discussed, particularly amphotericin B, as well as the importance of differential diagnosis between ATRA syn-drome and infectious diseases.
