Benefit and Risk of Tofacitinib in the Treatment of Rheumatoid Arthritis: A Focus on Herpes Zoster

Abstract The biologics have revolutionized the treatment of rheumatoid arthritis (RA). However, there are still patients that are difficult to control and a cure is still not achievable. Tofacitinib, a Janus kinase (JAK) inhibitor is an orally available, new-in-class, disease-modifying anti-rheumatic drug with similar efficacy to biologics. JAK is activated by multiple cytokines involved in the pathology of RA, and affects non-immune and immune cells, mainly the lymphocytes. Besides its anti-rheumatic effect, the recent focus has been on adverse events. As with other biologics, serious infections have been observed especially with patients with lymphopenia, consistent with the mechanism of action. The major difference in adverse events from other disease-modifying anti-rheumatic drugs is the prominent increase in the occurrence of herpes zoster; it is increased worldwide, especially in Asia. There are other concerns such as malignancies and hyperlipidemia that may cause cardiovascular events that deserve further attention. The first JAK inhibitor for RA is demonstrating great benefit along with some risk, providing insights into the post-biologic era.

CONCLUSION: In RA patients with an inadequate response to MTX, baricitinib 4 mg + MTX and upadacitinib 15 mg + MTX showed the highest ACR response rates, suggesting a difference in efficacy among the different JAK inhibitors. PMID: 32055928 [PubMed - as supplied by publisher]

Abstract OBJECTIVE: To assess vaccination coverage and predictors of vaccination among a Canadian population of rheumatology patients in routine clinical care. METHODS: In this cross-sectional study, consecutive adult patients presenting to a tertiary rheumatology clinic at the McGill University Health Center between May and September 2015 were asked to fill a survey on vaccination. Patients self-identified as having rheumatoid arthritis (RA), systemic autoimmune rheumatic diseases (SARD), spondyloarthropathies (SpA), or other diseases (OD). Multivariate logistical regression analyses were performed to evalua...

AbstractObjectiveTo evaluate efficacy, including inhibition of radiographic progression, and safety of upadacitinib, a JAK1 ‐selective inhibitor, vs placebo and adalimumab in patients with rheumatoid arthritis and an inadequate response to methotrexate.Methods1629 patients with inadequate response to methotrexate were randomized (2:2:1) to once ‐daily upadacitinib 15mg, placebo, or adalimumab 40mg, on stable background methotrexate. Primary endpoints were ACR20 and DAS28CRP

ConclusionThis population-based study revealed an increasing prevalence of biologic prescribing. Results from the study described the long-term retention rates and incidence rates of serious infections of biologic treatments for all indications, and confirmed the safety of biologic treatments. Since this study provides an overview of all biologic utilization, further studies on cost effectiveness, safety and compliance of treatment in different patient groups are still warranted.

Discussion The mandible normally grows in a symmetric downward and forward movement relative to the skull base. The condyle is the primary growth center. “The mandible is unique in that its 2 joints and growth centers function together as a single unit.” It is the last bone in the body to reach skeletal maturity. The mandible and its growth are important for maxillary growth and therefore many problems that affect the mandible affect the facial and skulls structures as well. These growth problems can be relatively insidious and therefore may need monitoring over longer periods of time such as patients with unde...

This study is active but not recruiting and is registered with ClinicalTrials.gov, number NCT02706951.FindingsPatients were screened between Feb 23, 2016, and May 19, 2017 and 648 were randomly assigned to treatment. 598 (92%) completed week 14. At week 14, an ACR20 response was achieved by 89 (41%) of 216 patients (95% CI 35–48) in the continued methotrexate group, 147 (68%) of 217 patients (62–74) receiving upadacitinib 15 mg, and 153 (71%) of 215 patients (65–77) receiving upadacitinib 30 mg (p

We present a case of an elderly, immunosuppressed patient with rheumatoid arthritis who was not appropriately vaccinated, and subsequently developed herpes zoster ophthalmicus, which initially presented similar to giant cell arteritis. Evidence ‐based vaccinations are integral in decreasing the incidence of preventable diseases and promoting optimal health at the individual and population level. Although the patient ultimately did not suffer any long‐term adverse sequelae, this case highlights the importance of vaccination in the rheum atology setting, and to consider both inflammatory and infectious causes of headache...
