Plasmapheresis therapy in combination with TNF-α inhibitor and DMARDs: A multitarget method for the treatment of rheumatoid arthritis

Abstract

Objective: To evaluate the effects of a multitarget method involving plasmapheresis therapy combined with tumor necrosis factor (TNF)-α inhibitor and disease-modifying antirheumatic drugs (DMARDs) on disease activity parameters in the treatment of active rheumatoid arthritis (RA).Methods: Sixty-five patients with active RA were divided into two groups according to the treatment administered: the plasmapheresis combination therapy group (Plasmapheresis combination group; 38 cases), in which patients received plasmapheresis therapy along with a TNF-α inhibitor (recombinant human tumor necrosis factor-Fc; rhTNFR:Fc; Etanercept biosimilars) and DMARDs, and a TNF-α inhibitor therapy group (biological agent group; 27 cases), in which patients received a TNF-α inhibitor and DMARDs. Clinical parameters were measured before and at 4 and 24 weeks after treatment.Results: ACR20, ACR50, and ACR70 responses at week 4 were achieved in 84.2%, 78.9%, and 60.5% of the patients in the plasmapheresis combination group, respectively, and 74.1%, 55.6%, and 29.6% of the patients in the biological agent group, respectively. The ACR50 and ACR70 response rates were superior in the former than the latter group (p < 0.05). Similar patterns of statistical significance were observed for ACR20, ACR50, and ACR70 responses at week 24 after the treatment. ACR50 responses were achieved in 84.2% patients and ACR70 responses were achieved in 76.3% patients in the plasmapheresis combination group, and these proportions were better than those in the biological agent group (p < 0.05).Conclusions: The multitarget method combining plasmapheresis, TNF-α inhibitor, and DMARDs for RA therapy was superior to the combination of TNF-α inhibitor for reducing disease activity parameters in patients with active RA.
