Background:
Identifying causes of alemtuzumab induced respiratory symptoms in Multiple Sclerosis (MS) patients is crucial.
Case Presentation:
We report a case of diffuse alveolar damage (DAD) in a patient with MS after the first course of alemtuzumab treatment. A 42-year-old female developed progressive non-productive cough and exertional dyspnea 2 months after alemtuzumab treatment. DAD was diagnosed histopathologically by lung biopsy. The patient recovered completely, alemtuzumab was not continued.
Conclusions:
Our case highlights another pathomechanism for non-infective lung-disorders in alemtuzumab treated MS patients. DAD is a potential, albeit rare side effect of alemtuzumab, broadening the spectrum of non-infective lung disorders that should be considered in the diagnostic work-up.
