Hemoptysis Resolution with Rituximab in Behçet's Disease: A Case Report.

Behçet's disease (BD) is a multisystem, progressive, and inflammatory disorder of unknown etiology. Vasculitis is believed to underlie various clinical manifestations of BD and is known to be one of the main causes of death due to BD, in cases of large vessel involvement. The current study is done in order to examine the effects of rituximab on the patient's debilitating clinical manifestations, as a result of not responding to the standard treatment regimens. The present case is a 28-year-old female patient with BD associated vasculitis. She was referred to the respiratory referral center, chiefly complaining of intermittent episodes of massive hemoptysis. She had also recurrent oral and genital ulcers, and difficulty in walking, despite considering the common treatment approaches for BD. Our patient received two courses of rituximab in combination with intravenous methylprednisolone. Over six months follow-up period from the date of treatment initiation with rituximab, symptoms of BD such as recurrent hemoptysis and aphthous ulcers were reduced in both frequency and severity. Lower limb weakness and difficulty in walking were improved as well. To summarize, rituximab appears to be an effective alternative for treatment-resistant vasculitis in BD patients.
