On Oct. 15, the U.S. Food & Drug Administration (FDA) approved the first interchangeable biosimilar product to treat certain inflammatory diseases. Cyltezo (adalimumab-adbm), originally approved in August 2017, is both biosimilar to and interchangeable with (i.e, may be substituted for) its reference product Humira (adalimumab) for Cyltezo’s approved uses. Cyltezo is the second interchangeable biosimilar…

Therapeutic Drug Monitoring May Offer Little Benefit to Patient Remission Rates During Infliximab Induction Therapy
Although rheumatologists prescribe tumor necrosis factor inhibitors (TNFi’s) to treat several rheumatic diseases, they recognize immunogenicity influences the efficacy and safety of TNFi’s. Example: The formation of anti-drug antibodies can affect infusion reactions and cause low-serum drug levels and therapeutic failure. The induction phase is a period of high incidence of immunogenicity, and observational data…
Case Report: A Mycobacterium kansasii Infection
A 61-year-old white woman presented to our rheumatology clinic in New England to establish care in early June 2018, following a move from Texas. She reported a medical history of inflammatory bowel disease, uveitis and seronegative inflammatory arthritis, which was difficult to control and required the use of multiple medications.

The Effects of IL-17A Inhibitors on the Microbiota
The use of an interleukin (IL) 17A inhibitor resulted in gut microbial dysbiosis and features of subclinical intestinal inflammation in a subgroup of psoriatic arthritis (PsA) and spondyloarthritis (SpA) patients, according to a multidisciplinary, collaborative study across several institutions published in Arthritis & Rheumatology.1 Understanding the downstream effects of these perturbations is an important step…
