RESUMO

OBJETIVO:

Analisar os resultados da espirometria de pacientes submetidos a transplante de medula óssea e verificar sua importância na detecção de complicações pulmonares e sua correlação com a evolução dos pacientes.

MÉTODOS:

Foram analisados retrospectivamente os resultados da espirometria em 120 pacientes, maiores de doze anos, de ambos os sexos, e comparados com o tipo de transplante de medula óssea, doença de base, sorologia para citomegalovírus, fonte de células para o transplante, tabagismo, infecção pulmonar, doença pulmonar prévia, duração da doença hematológica, quimioterapia utilizada, regime de condicionamento, doença do enxerto contra o hospedeiro aguda e crônica e óbito.

RESULTADOS:

Dezesseis pacientes apresentaram alterações da espirometria antes do transplante, sendo 5 por cento com obstrução pura, 5,8 por cento com restrição pura e 2,5 por cento com obstrução com redução da capacidade vital. Após o transplante 29 pacientes apresentaram alterações desses exames. A chance de alteração da espirometria foi maior nos pacientes com doença do enxerto contra o hospedeiro aguda (p = 0,02), idade menor que 30 anos (p = 0,02), sexo feminino (p = 0,02) e naqueles que receberam células tronco (p = 0,01). As presenças de doença pulmonar prévia e doença do enxerto contra o hospedeiro crônica associaram-se com aumento da mortalidade. Alterações prévias da espirometria não estiveram relacionadas com o óbito pós-transplante.

CONCLUSÃO:

As alterações detectadas na espirometria não foram capazes de predizer a ocorrência de complicações pulmonares e óbito pós-transplantes. Também não foram determinantes para a não realização do procedimento. A espirometria simples realizada na avaliação desses pacientes parece ter pouca importância prática.
ABSTRACT

OBJECTIVE:

To analyze the spirometry findings in patients undergoing bone marrow transplant, determining the importance of such findings in predicting postoperative pulmonary complications and looking for correlations with postoperative outcomes.

METHODS:

The spirometry findings in 120 male and female patients, all above the age of 12, were evaluated retrospectively and compared in terms of the following parameters the type of bone marrow transplant; the underlying disease; cytomegalovirus serology; source of the transplanted cells; smoking; pulmonary infection; history of lung disease; duration of the hematological disease; chemotherapy employed; conditioning regimen; acute or chronic rejection of the transplant; and post-operative mortality.

RESULTS:

In the pre-operative spirometry, 16 patients (13.3 percent) presented alterations 6 (5 percent) presented pure obstruction; 7 (5.8 percent) presented pure restriction; and 3 (2.5 percent) presented obstruction accompanied by a reduction in vital capacity. In the post-operative spirometry, 29 patients (24.2 percent) presented alterations. The chance of presenting post-operative spirometry alterations was greater in patients presenting acute transplant rejection (p = 0.02), patients older than 30 (p = 0.02), female patients (p = 0.02) and patients receiving stem cells (p = 0.01). Having a history of lung disease was found to be associated with greater mortality, as was suffering from chronic transplant rejection. No relationship was found between pre-operative spirometry alterations and post-operative mortality.

CONCLUSION:

In bone marrow transplant patients, the alterations found through pre-operative spirometry were not predictive of post-operative pulmonary complications or mortality. Nor were such alterations determinant of whether or not a given patient was a good candidate for bone marrow transplant. Simple spirometry seems to be of little practical importance in the evaluation of such patients.
