Modern immunosuppressive therapy may be responsible for toxic, immunologic and infectious pulmonary diseases.
We report the case of a 58-year old woman treated for rheumatoid arthritis who received leflunomide, corticosteroids, methotrexate and adalimumab. She developed disseminated tuberculosis, which presented with neurological symptoms (brainstem) and also pneumocystis pneumonia.
Modern immunosuppressive therapy used to treat inflammatory disorders in connective tissue diseases and in transplantation may induce new respiratory diseases, new patterns of known respiratory diseases or co-infections that are very seldom seen outside the context of HIV. Pulmonologists, rheumatologists, internists and intensivists should be aware of this new spectrum of diseases whose presentation may be atypical.
