Abstract:


Background: Granulomatosis with polyangiitis is a systemic anti-neutrophil cytoplasmic antibody-associated vasculitides (AAVs), mainly involving the respiratory tract and renal system. Treatment by Rituximab as a next-generation therapy in ANCA-associated vasculitis was associated with promising outcomes in GPA patients. Despite symptoms improvements, disease recurrence and drug reaction was a challenging topic nowadays.

Objectives: In this study, we examined six GPA patients who were confirmed to have paradoxical reactions to rituximab and then described How to control their symptoms.

Methods: In this study, all the systemic GPA patients (diagnosed based on ACR/EULAR criteria) who received RTX in Amir-Allam hospital, were monitored for any sign of disease exacerbation up to 3 months after RTX exposure.

Results: From 78 GPA-diagnosed patients, six, including one man and five women with the mean age of 37.3 ± 13.8, were identified for exacerbation after RTX administration.

Conclusion: According to our observation, it could be recommended that not to deprive the patient of the benefits of RTX treatment due to the early patient's possible complications.
