Abstract:
The treatment of rheumatoid arthritis (RA) has advanced from the use of steroids to disease-modifying anti-rheumatic drugs (DMARDs) and biologics such as tumor necrosis factor (TNF) and interleukin-6 (IL-6) inhibitors. Historically, steroids have been the mainstream in the clinical treatment of RA; however, the development of DMARDs has changed the RA treatment structure. In addition, biologics can alleviate RA symptoms. This case report describes the secondary failure of tocilizumab in treating RA with fatigue symptoms. Treatment with tocilizumab decreases C-reactive protein (CRP) levels, which may make detecting RA exacerbation difficult; therefore, obtaining the patient's precise history and thorough physical examinations are necessary. This case demonstrates the complexity of treating elderly-onset RA and reports practical methods for effective treatment.
