[Nocardial infection after allogeneic hematopoietic stem cell transplantation].
In order to explore the diagnosis and therapeutic effectiveness of nocardiosis after allogenic hematopoietic stem cell transplantation (allo-HSCT), the features of clinical manifestation, laboratory examination and response to TMP-SMZ treatment in two cases of nocardiosis after allo-HSCT were analyzed retrospectively. The result showed that the attack happened to 2 patients at day 15 and 170 after allo-HSCT respectively, displaying fever and chest pain. Chest CT scan indicated bilateral pulmonary tuberculous shadow. Nocardiosis was diagnosed by the culture of sputum, bronchoalveolar lavage (BAL) fluid and pus samples as well. Both of these cases exhibited good response to combined therapy containing TMP-SMZ for half a year. It is concluded that nocardiosis is a rare complication after allo-HSCT, in which pulmonary involvement is commonly observed. The culture of BAL fluid is helpful for its diagnosis and this disease might be sensitive to the treatment of TMP-SMZ-containing regimens.
