Objective: This study aims to observe the clinical efficacy of low-dose rituximab in patients with cryoglobulinaemia secondary to connective tissue diseases.
Methods: Rituximab (100 mg) was infused in patients once a week for four weeks, combined with prednisone (20 mg) once a day, and reduced regularly. Treatment effect was observed regularly.
